The invention provides an immersed tube sinking device with adjustable distance.

Please refer to FIG. 1 and FIG. 2 in combination, in an embodiment of the present invention, the immersed tube sinking device includes a guide member 1 and a sinking assembly 2; wherein, at least part of the structure of the guide member 1 is used to be inserted on the bottom of the water; The sinking assembly 2 includes a connecting frame 22 and a sinking body 21. The connecting frame 22 is used for fixed connection with the sinking tube 8. The sinking body 21 is detachably connected to the side of the connecting frame 22 away from the sinking tube 8. The sinking body 21 It is connected with the guide piece 1 and can move along the extension direction of the guide piece 1 .

In an embodiment of the present invention, the guide member 1 is mainly used to locate the preset placement position of the immersed tube 8, and at the same time guide the immersed tube 8 when it is sunk, so as to accurately sink the immersed tube 8. Place the preset placement position. It can be fixed by inserting it on the bottom of the water. Of course, in order to improve the fixing effect of the guide member 1, a clamping block can be further arranged on the part of the guide member 1 exposed on the water surface to connect the fixed object on the shore. In this way, the guide member 1 is stably fixed to the preset placement position of the immersed tube 8 , reducing the shaking of the guide member 1 caused by the fluctuation of the water flow, thereby improving the guiding accuracy of the sinking tube 8 of the guide member 1 . The connecting frame 22 is mainly used for fixed connection with the sinking tube 8, so that the sinking tube 8 can be driven to descend with the sinking assembly 2 when the sinking tube 8 is sinking. The sinking body 21 is mainly used to connect with the guide member 1, so that the sinking assembly 2 can descend along the extending direction of the guide member 1 when the sinking tube 8 is sinking, thereby indirectly realizing the sinking of the sinking tube 8. put to guide.

When the immersed tube sinking device according to the technical solution of the present invention sinks the immersed tube 8, at least part of the structure of the guide member 1 is inserted into the water bottom of the preset placement position of the immersed tube 8, so that the guide member 1 can be placed in the immersed tube 8. 8 The positioning of the preset sinking position. Then, the connecting frame 22 of the sinking assembly 2 and the sinking tube 8 are fixedly connected to realize the fixation between the sinking device and the sinking tube 8 . Since the sink body 21 of the sink assembly 2 is connected with the guide member 1 , it can move along the extension direction of the guide member 1 . During the process of sinking the immersed tube 8 under its own gravity, the movement of the sinking body 21 is guided by the guide member 1, which indirectly realizes the guidance of the sinking process of the sinking tube 8, that is, the sinking is achieved. The tube 8 can only be deposited along the extension direction of the guide 1 . In this way, compared with the prior art, the sinking barge is easily affected by the impact of water flow during the sinking process, so that the sinking position of the immersed tube 8 is easily deviated from the preset sinking position. In this solution, the immersed tube 8 can be positioned by the guide member 1 during the sinking process, so that the immersed tube 8 can be accurately placed above the preset sinking position; and under the indirect guiding action of the guide member 1, the immersed tube 8 can be Accurately sinking to the preset sinking position, thereby improving the sinking construction accuracy of the immersed tube 8 .

Moreover, the sinking assembly 2 is set to include a connecting frame 22 and a sinking body 21, so that the sinking assembly 2 can be connected to the sinking tube 8 through the connecting frame 22, and a fixing structure is conveniently arranged on the connecting frame 22 to fix the sinking The assembly 2 and the immersed tube 8 can improve the convenience of fixing the immersed tube 8 to the immersed tube sinking device. Further, the sink body 21 is detachably connected to the side of the connection frame 22 away from the sink tube 8 , so that when the sink body 21 is damaged, it can be removed from the connection frame 22 for replacement. In this way, when a part of the sinking body 21 is damaged, the sinking assembly 2 needs to be replaced as a whole, thereby reducing the replacement cost of the sinking device. The sinking body 21 is connected to the side of the connecting frame 22 away from the sinking tube 8 , so that the sinking body 21 , the connecting frame 22 and the sinking tube 8 are sequentially distributed from top to bottom. It can make the sink body 21 and the sink tube 8 have a larger installation space on the connection frame 22 to facilitate their installation, and also avoid the sink body 21 and the sink tube 8 because they are located on the same side of the connection frame 22. The possibility of interference occurs, thereby improving the safety of the immersed body 21 and the immersed tube 8 during installation and fixation.

In an embodiment of the present invention, the sink body 21 is provided with a slideway 21a, the slideway 21a is extended along the movement direction of the sinker body 21, and at least part of the structure of the guide member 1 is embedded in the slideway 21a, and abuts against the slideway 21a. Connected to the inner wall of the slideway 21a.

It can be understood that the sinking body 21 is connected with the guide member 1 through the slideway 21a, so that the sinking body 21 can move along the extending direction of the guide member 1, that is, it is ensured that the guide member 1 can guide the sinking assembly 2 along with the sinking tube. 8 is placed and guided. At the same time, the connection structure of the sinking body 21 and the guide member 1 is simplified, so that the two do not need to be connected with a complicated structure, thereby reducing the processing and manufacturing cost of the immersed tube sinking device. The slideway 21a is arranged on the sinking body 21, which ensures the strength of the guide member 1 and improves its resistance to fluctuations in water flow, thereby improving the stability of the guide member 1 to the immersed tube 8 during the sinking process. sex. Further, since the inner wall of the slideway 21a can be distinguished from other wall surfaces of the sink body 21, the roughness is relatively low, that is, the inner wall of the slideway 21a is relatively smooth, which can reduce the speed of the sinker body 21 along the guide member 1. The friction force when moving in the extending direction of the immersed tube can improve the efficiency of the sinking tube 8; it also reduces the relatively large wear of the sinking body 21 and the guide 1 due to the relative movement, so that the sinking body 21 and the guide can be extended. 1 years of use. Of course, the present application is not limited to this. In other embodiments, the connection between the sink body 21 and the guide member 1 may also be the cooperation of the slide rail and the slider, that is, the guide member 1 is provided with a slide rail, and the slide rail is guided along the guide. The extension direction of the part 1 is extended and arranged; the sink body 21 is provided with a sliding block, and the sliding block is slidably connected to the sliding rail.

Please refer to FIG. 1 and FIG. 7 , in an embodiment of the present invention, the sink body 21 includes a main body 211 and two clamping arms 212 ; the main body 211 has opposite ends, and one end of the main body 211 Removably connected to the side of the connecting frame 22 away from the sinking tube 8 ; the two clamping arms 212 are provided at the other end of the main body portion 211 and are located on opposite sides of the main body portion 211 perpendicular to the movement direction of the sinking body 21 , the opposite surfaces of the two clamping arms 212 and the end surface of the main body portion 211 close to one end of the two clamping arms 212 are enclosed to form a slideway 21a.

It can be understood that since the guide member 1 is pre-fixed to the preset placement position of the sinker tube 8, the connection process between the main body 211 of the sinker body 21 and the guide member 1 is generally performed by the sinking body 21 approaching the guide member 1 and then performing butt connection. of. The slideway 21a is formed by enclosing the two clamping arms 212 and the main body 211, so that the slideway 21a does not form a closed shape. Therefore, when the main body portion 211 of the sink body 21 is approaching the guide member 1, the guide member 1 can be inserted into the slideway 21a from the opening formed by the ends of the two clamping arms 212 away from the main body portion 211, which can be quickly completed. The guide member 1 of the sink body 21 is connected. In this way, the complexity of docking between the two under relatively complex water conditions is reduced, so that the docking efficiency of the sinking body 21 and the guide member 1 can be improved. At the same time, the sliding is only formed by the main body 211 of the sink body 21 and the two clamping arms 212, that is, the slideway 21a only includes three connected inner walls, which can reduce the complexity of forming the slideway 21a; The road 21a requires less production raw materials, so that the production cost can be reduced. Moreover, the facing surfaces of the two clamping arms 212 and the end surface of the main body portion 211 close to one end of the two clamping arms 212 are enclosed to form a slideway 21a, so that the two clamping arms 212 are parallel to the centerline of the horizontal plane and the main body portion. The centerlines of 211 parallel to the horizontal plane may be located on the same horizontal plane. In this way, the thickness of the sink body 21 can be reduced, thereby reducing the occupation of space. Further, the two clamping arms 212 and the main body 211 may be provided in an integral structure, so as to improve the strength of the two at the connection point and ensure the clamping and connection effect of the sink body 21 on the guide member 1 , thereby improving the guide member 1 . Guiding effect on the sink body 21 . Of course, the two clamping arms 212 and the main body portion 211 may be provided in separate structures and fixed by welding. In this way, it can be separately manufactured to reduce the complexity of processing, and welding is adopted to ensure a relatively stable connection effect between the two when assembled as a whole; at this time, the formation of the slideway 21a does not need to be on the main body portion 211. The opening can be formed by assembling the two clamping arms 212 and the main body 211 , so that the complexity of forming the slideway 21 a can be further reduced. In addition, it should be noted that the present application is not limited to this, and in other embodiments, the slideway 21 a may also be formed by opening a through hole inside the main body 211 of the sink body 21 . In an embodiment of the present invention, two slideway reinforcing ribs 213 are provided at the connection between each clamping arm 212 and the main body portion 211 . opposite sides of the direction of motion.

It can be understood that the provision of the slideway reinforcement rib 213 can enhance the strength of the clamping arm 212 and the main body portion 211 at the connection position and improve the connection effect of the two, thereby further ensuring the clamping connection of the sink body 21 to the guide member 1 effect, so as to further improve the guiding effect of the guide member 1 on the sink body 21 . The two slideway reinforcing ribs 213 are respectively located on opposite sides of the main body portion 211 in the movement direction of the sinking body 21 , which can ensure the enhancement of the connection strength of the slideway reinforcing ribs 213 to the clamping arm 212 and the main body portion 211 . Effect; also reduces the number of slideway reinforcing ribs 213 and reduces the structural complexity of the two at the connection, as well as the manufacturing cost. In an embodiment of the present invention, one end of the two clamping arms 212 away from the main body portion 211 is provided with a first lifting member 2111 , the two first lifting members 2111 are disposed oppositely, and the main body portion 211 is away from the two clamping arms 212 There are two second hoisting members 2111 at one end, the two second hoisting members 2111 are located on opposite sides of the main body portion 211 perpendicular to the movement direction of the sink body 21, the two first hoisting members 2111 and the two second hoisting members 2111 Each of the components 2111 is provided with a lifting hole 2111a.

It can be understood that the arrangement of the first hoisting member 2111 and the second hoisting member 2111 facilitates the lifting, assembly and transportation of the sink assembly 2, that is, the locking hook of the hoisting device can pass through the hoisting hole 2111a and be hooked to the first hoisting member 2111 and the second hoisting member 2111. By lifting the hoisting member 2111, the connection between the sinking body 21 and the hoisting device can be realized, and the sinking body 21 can be hoisted by the hoisting device. The first hoisting member 2111 and the second hoisting member 2111 are provided with hoisting holes 2111a, which can simplify the connection structure of the sinking body 21 and the hoisting device, which is convenient for the operator to connect the lock hook to the hoisting device under complex underwater or underwater conditions. The first lifting member 2111 and the second lifting member 2111 are connected. Of course, the present application is not limited to this, and in other embodiments, the connection between the locking hook and the first hoisting member 2111 and the second hoisting member 2111 may also be connected by a snap. In addition, the two first hoisting members 2111 are arranged at one end of the two clamping arms 212 away from the main body portion 211, and are arranged opposite to each other; Located on opposite sides of the main body portion 211 perpendicular to the movement direction of the sinking body 21, so that the two first lifting members 2111 and the two second lifting members 2111 are distributed on the opposite ends of the sinking body 21, namely the two first lifting members 2111. The hanging piece 2111 and the two second hoisting pieces 2111 have a large span, which improves the stability of the connection to the sinking body 21 and reduces the possibility of the perimeter of the sinking body 21 shaking.

In an embodiment of the present invention, the immersed tube sinking device further includes at least two abutting members 3, wherein one of the two abutting members 3 is selectively and movably connected to one clamping arm 212, and two The abutting members 3 move in the direction of approaching or moving away from each other, the two abutting members 3 can be limited and fixed to the clamping arms 212 corresponding to the abutting members 3, and the two clamping members 23 are close to each other and can clamp and fix the guide Part 1, the two abutting parts 3 and the end face of the main body part 211 close to one end of the guide part 1 can all abut against the guide part 1 located in the slideway 21a.

It can be understood that the two abutting members 3 are movably disposed on the clamping arm 212, so that the distance between the two abutting members 3 can be adjusted. At this time, the distance between the two clamping arms 212 can be set greater than the distance between the opposite sides of the guide member 1 on the longitudinal section parallel to the end face of the main body portion 211 close to the end face of the guide member 1, so that the body 21 is placed When the main body portion 211 is connected to the guide member 1 , the two clamping arms 212 can be used for preliminary alignment, and then the two abutting arms 212 can approach the guide member 1 for clamping and fixing. In this way, the alignment accuracy of the main body portion 211 of the sinking body 21 and the guide member 1 during butt connection is reduced, so that the sinking efficiency of the sinking tube 8 can be further improved. Moreover, the distance between the two abutting members 3 can be adjusted so that the main body 211 of the sink body 21 can be connected with guide members 1 of different sizes, thereby improving the versatility of the sink body 21 in use. At the same time, the two abutting members 3 and the end face of the main body 211 close to the guide member 1 can abut against the guide member 1 located in the slideway 21a, so that the clamping area of the sink body 21 to the guide member 1 can be reduced. By reducing the friction force between the two, the friction force caused by the movement of the sinking body 21 relative to the guide member 1 can be improved, thereby improving the sinking efficiency of the immersed tube 8 . In addition, the two abutting members 3 are close to each other to clamp and fix the guide member 1, and the two abutting members 3 are far away from each other to realize the separation of the guide member 1, so that the two can be disassembled and separated to facilitate their recycling. Wherein, the number of abutting members 3 may be two, of course, there may be more, and more are distributed at intervals along the circumferential direction of the guide member 1 to clamp, abut and fix the guide member 1 from different directions. .

In an embodiment of the present invention, the two clamping arms 212 are provided with a sliding hole 212a communicating with the slideway 21a, and an abutting member 3 is slidably embedded in one sliding hole 212a.

It can be understood that the abutting member 3 is slidably connected to the clamping arm 212 , so that the abutting force of the abutting member 3 to the guide member 1 is parallel to the sliding direction of the abutting member 3 . At this time, the abutting member 3 is opposite to the guide member 1 The abutting force of can be relatively perpendicular to the guide member 1, so that the abutting effect of the abutting member 3 on the guide member 1 can be improved. However, embedding the abutting member 3 in the sliding hole 212a can make the distribution of the abutting member 3 and the clamping arm 212 more compact, reduce the overall volume of the sinking body 21 and reduce the sinking body 21 when the sinking tube 8 sinks. The descending movement resistance caused by the buoyancy of the water current can further improve the sinking efficiency of the immersed tube 8 . Moreover, the sliding hole 212a also has a guiding effect on the sliding of the abutting member 3, so that the abutting member 3 can only slide along the extending direction of the sliding hole 212a, thereby improving the stability of the abutting member 3 during the sliding process. The accurate abutment of the abutting member 3 to the guide member 1 is ensured, thereby improving the clamping and abutting effect of the abutting member 3 to the guide member 1 . In addition, the sliding hole 212 a also provides a certain installation space for the abutting member 3 , which can prevent the abutting member 3 from being easily damaged because most of the abutting member 3 is exposed, so as to extend the service life of the abutting member 3 . Wherein, the shape of the sliding hole 212 a can be set in a square shape, and of course can also be set in a circular shape, and its shape can be set according to the shape of the cross section of the abutting member 3 . In addition, it should be noted that in other embodiments, one end of the abutting member 3 may also be rotatably connected to the clamping arm 212 , and the other end is abutted against the sliding arm 212 through the rotation of the abutting member 3 relative to the clamping arm 212 . The abutment 3 in the channel 21a.

In an embodiment of the present invention, the guide member 1 is arranged in a circular shape on a projection plane perpendicular to the moving direction of the sink body 21 , and the two abutting members 3 abut a part of the half peripheral surface of the guide member 1 . position, the end surface of the main body portion 211 close to one end of the clamping arm 212 is in contact with a part of the other half peripheral surface of the guide member 1 .

It can be understood that the end surface of the main body portion 211 close to one end of the clamping arm 212 is in contact with the other half of the peripheral surface of the guide 1 by the two abutting members 3 abutting on the part of the half peripheral surface of the guide member 1 . Location. The guide member 1 is limited in the length direction of the main body portion 211 , and the two abutting members 3 are arranged opposite to each other, so that the guide member 1 is also limited in the width direction of the main body portion 211 . That is to say, only two abutting members 3 and one main body portion 211 can limit the position of the guide member 1 in four directions, but only along the height direction of the main body portion 211 (the extension direction of the guide member 1 ). The relative movement can ensure the clamping and fixing effect of the guide member 1, thereby improving the guiding accuracy of the guide member 1 to the sink body 21; it can also simplify the setting of the clamping mechanism, thereby reducing the manufacturing cost.

In an embodiment of the present invention, the side of the two abutting members 3 facing the guide member 1 is provided with abutting guide inclined surfaces 31 . The distance between the

It can be understood that the setting of the abutment guide slope 31 makes the abutment guide slope 31 of the abutment member 3 parallel to the tangent of the guide member 1 in the circumferential direction, and can abut the guide member 1 at the middle position of the abutment guide slope 31 It is ensured that the abutting member 3 and the abutting surface can be well matched and abutted, so that the abutting member 3 can exert an abutting force on the guide member 1 through the abutting guiding inclined surface 31, thereby further improving the pairing of the abutting member 3 to the guide member 1. The clamping and abutting effect of the guide 1 . Moreover, the abutting member 3 is provided with abutting guide slopes 31, so that when the sink body 21 is separated from the guide member 1, that is, when the sink body 21 moves in a direction away from the guide member 1, the two abutting members 3. Under the guidance of the abutting guide inclined surface 31, it can automatically slide in a direction away from each other, so as to improve the convenience of disassembling and separating the sink body 21 and the guide member 1.

In an embodiment of the present invention, in the direction in which the guide member 1 is close to the main body portion 211 , the distance between the two slideway reinforcing ribs 213 is increased.

It can be understood that, the inclination direction of the side wall of the slideway reinforcement rib 213 and the inclination direction of the abutting guide inclined surface 31 can be symmetrically arranged, that is, the sidewall of the slideway reinforcement rib 213 and the guide member 1 in the circumferential direction can be arranged symmetrically. The tangent lines are also arranged in parallel, so that the slideway reinforcing rib 213 and the guide member 1 can be well matched and abutted, and it is convenient for the slideway reinforcing rib 213 to exert an abutting force on the guide member 1 . At this time, the two semi-circumferential surfaces of the guide member 1 can be clamped, abutted and limited by the cooperation of the abutment guide inclined surfaces 31 of the two abutting members 3 and the side walls of the two slideway reinforcing ribs 213, which can further Improve the clamping and fixing effect of the sinking body on the sinking body 21 on the guide member 1 and improve the stability of the sinking body 21 when moving along the extension direction of the guide member 1, so as to ensure that the sinking tube 8 passes through the sinking body during the sinking process. 21 is placed along the extending direction of the guide member 1 to be accurately placed at the preset placement position.

In an embodiment of the present invention, an abutment cushion is embedded at the abutment between the two abutting members 3 and the guide member 1 ; Abutting buffer pads; abutting buffer pads are embedded in the abutment between the main body portion 211 and the guide member 1 ; the abutting buffer pads can abut on the guide member 1 .

It can be understood that when the two abutting members 3 are in clamping contact with the guide member 1 , when the two slideway reinforcing ribs 213 are in abutment with the guide member 1 , and the main body portion 211 and the guide member 1 When the abutment is performed, buffering is performed to avoid damage to the guide member 1 when the two abutment, the two slideway reinforcing ribs 213 and the end face of the main body portion 211 facing the guide member 1 collide with the guide member 1, so that the sinking can be improved. The safety of the body 21 and the guide member 1 during butt connection. And the setting of the abutting buffer pad can make the abutting buffer pad can be accommodated in the abutting member 3 or the slideway after corresponding deformation when the abutting buffer pad is pressed by the guide member 1 . Inside the reinforcing rib 213 , or inside the main body portion 211 . At this time, the abutting member 3 , the slideway reinforcing rib 213 and the main body portion 211 can still be rigidly abutted with the guide member 1 through the position without the abutting buffer pad, so as to have a better clamping and fixing effect on the guide member 1 . . At the same time, the embedding arrangement of the abutting cushion can also increase the contact area between the abutting cushion and the abutting member 3 , the abutting cushion and the chute reinforcement rib 213 , and the abutting cushion and the main body 211 , thereby enhancing the contact area. The stability of the contact buffer pad is fixed, reducing the possibility of the contact buffer pad falling off due to long-term friction when the sink body 21 moves along the extending direction of the guide member 1, and ensuring the sink body 21 along the extending direction of the guide member 1. The normal and stable progress of the movement. Of course, the embedded arrangement of the abutting buffer pad can also make the installation of the abutting buffer pad more compact.

Please refer to FIG. 1 , FIG. 10 and FIG. 11 , in an embodiment of the present invention, the immersed tube sinking device further includes at least two abutting and limiting components 4 , and each abutting and limiting component 4 includes abutting threads The rod 41, the first abutting nut 42 and the second abutting nut 43; one end of an abutting threaded rod 41 is connected to a clamping arm 212 and extends along the sliding direction of the abutting member 3, and one abutting threaded rod 41 passes through a part of the structure of an abutment member 3, and the abutment member 3 can slide relative to the abutment threaded rod 41 under the action of external force; a first abutment nut 42 and a second abutment nut 43 can be slidably sleeved It is arranged on the side peripheral surface of one abutting threaded rod 41 and abuts on the side of one abutting member 3 facing and facing away from the other abutting member 3 respectively.

Specifically, when it is necessary to drive the two abutting members 3 to slide to abut the clamping guide member 1, the first abutting nut 42 is rotated to move a certain distance in the direction facing the guide member 1, so that the first abutment nut 42 is moved for a certain distance. The nut 42 is not in contact with the abutting member 3 . At this time, the abutting member 3 is not limited and fixed, and under the action of external force, the two abutting members 3 can slide relative to the abutting threaded rod 41 to approach the guide member 1 , so as to realize the clamping and abutting of the guide member 1 , and by rotating the second abutting nut 43 to move the same distance in the direction facing the guide member 1 to abut the side of the abutting member 3 away from the guide member 1, so as to realize the limit of the abutting member 3 fixed. Similarly, when the guide member 1 and the abutment member 3 need to be disassembled and detached, the second abutment nut 43 is rotated to move a certain distance in the direction away from the guide member 1, so that the second abutment nut 43 is not abutted on the abutment piece 3. At this time, the abutting member 3 is not limited and fixed, and under the action of external force, the two abutting members 3 can slide relative to the abutting threaded rod 41 and move away from the guiding member 1, so as to realize the connection between the guiding member 1 and the abutting member 3. of disassembly. It can be understood that, in this solution, the first abutment nut 42 and the second abutment nut 43 are used to realize the limit fixation of the abutment member 3, and the threaded connection is relatively stable and simple, so that the abutment member can be ensured The limiting and fixing effect of 3 is also convenient for the operator to release the limitation of the abutting member 3 to separate the sinking body 21 and the guiding member 1 under relatively complex underwater working conditions. Moreover, since there is no electrical/pneumatic circuit arrangement, the threaded connection can ensure that it can work in relatively complex underwater conditions, that is, the first abutment nut 42 and the second abutment nut 43 are used to realize the connection of the abutment member 3. The position-limiting and fixed position-limiting structure avoids being affected by the water flow and ensures the position-limiting and fixing effect on the abutting member 3 . Moreover, the threaded connection also facilitates the operation to control the moving distance of the abutting member 3 relative to the clamping arm 212 , so that the abutting member 3 can be accurately limited and fixed at the preset fixed position, so as to prevent the moving distance of the abutting member 3 from being too large. Clamping the guide 1 too tightly will cause the guide 1 to be clamped and damaged; it is also avoided that the moving distance of the abutment 3 is too small and the guide 1 is clamped too loosely, resulting in the abutment 3 not being able to be stably clamped and abutted. Connecting to the guide member 1 affects the guiding effect of the guide member 1 on the sinking body 21 , thereby affecting the sinking construction accuracy of the immersed tube 8 . In addition, it should be noted that the present application is not limited to this, and in other embodiments, the limiting and fixing structure for the abutting member 3 may also be a combination of a clamping post and a clamping groove. Specifically, the clamping arm 212 is provided with a plurality of card slots, which are distributed at intervals along the sliding direction of the abutting member 3; inside, so that the abutting member 3 is limited and fixed to the clamping arm 212 .

It can be understood that the end of the abutting threaded rod 41 away from the clamping arm 212 can be fixed by the first fixing seat 2141 and the second fixing seat 2142 of the threaded rod fixing frame 214, thereby reducing the possibility of the abutting threaded rod 41 shaking, thereby reducing the possibility of the abutting threaded rod 41 shaking. The stability of the abutting member 3 pierced on the abutting threaded rod 41 can be improved, and the abutting and clamping effect of the abutting member 3 on the guide member 1 can be ensured. Wherein, the first fixing base 2141 and the second fixing base 2142 can be both channel steel, so as to reduce the use of production raw materials and reduce the manufacturing cost of the threaded rod fixing frame 214 . In order to connect the abutting member 3 with the abutting threaded rod 41 , the abutting member 3 may be protruded with abutting connecting lugs 32 , the abutting threaded rod 41 passes through the abutting connecting lugs 32 , and a first abutting nut 42 A second abutting nut 43 is respectively abutted on the side of one abutting connecting lug 32 facing and facing away from the guide member 1 . In this way, the abutting threaded rod 41 does not need to pass through the abutting member 3 to ensure the strength of the abutting member 3 , so that the abutting member 3 can stably abut the guide member 1 . Further, the abutment member 3 may be protruded with two abutment connection ears 32 on two opposite sides of the abutment member 3 . The connecting nut 42 and the two second abutting nuts 43; one end of the two abutting threaded rods 41 is connected to one clamping arm 212, and the other end is connected to the second fixing seat 2142 of the threaded rod fixing member, and the first abutting thread The rod 41 passes through an abutting connecting ear 32 ; a first abutting nut 42 and a second abutting nut 43 are sleeved on an abutting threaded rod 41 and respectively abut on the upper abutment of the abutting threaded rod 41 . The connecting lug 32 faces and faces away from the side of the guide member 1 . In this way, the possibility of shaking of the abutting member 3 can be further reduced, and the stability of the abutting member 3 in the sliding process can be improved; It can also make the limit abutting force of the first abutting nut 42 and the second abutting nut 43 to the abutting piece 3 evenly distributed, so as to avoid stress concentration caused by single-point fixing and affecting the limit of the abutting piece 3 Fixed effect.

It can be understood that after the first abutment nut 42 is rotated to move a certain distance in a direction facing the guide member 1 , the abutment member 3 can be driven to slide in a direction close to the guide member 1 by abutting the driving member. In this way, the operator does not need to manually push the abutting member 3 to slide, so that the labor intensity of the operator can be reduced. At the same time, by controlling the simultaneous activation of the two abutment drive members, the two abutment members 3 can be simultaneously slid in the direction of approaching each other, so that the two abutment members 3 abut the guide member 1 at the same time, so that the guide member 1 is subjected to The collision force of the two abutting members 3 is offset to be firmly placed between the two abutting members 3 , wherein the abutting driving member can be an air cylinder or a jack.

In an embodiment of the present invention, the side of the second fixing base 2142 facing the clamping arm 212 is provided with a driving member bearing seat 2143 , and the driving member bearing seat 2143 includes a first bearing plate 2143a and a second bearing plate 2143b. Both the bearing plate 2143a and the second bearing plate 2143b are connected to the second fixing seat 2142 and are arranged at an included angle, and the abutting driving member is detachably arranged between the first fixing seat 2141 and the second fixing seat 2142, and is held by the first fixing seat 2141 and the second fixing seat 2142. A fixing base 2141 and a second fixing base 2142 are clamped and fixed.

It can be understood that the abutting driving member is detachably arranged on the driving member bearing seat 2143, so that when the abutting member 3 needs to be driven to slide to clamp the guide member 1, the abutting driving member can be installed on the driving member bearing seat 2143 and after the abutting member 3 clamps and fixes the guide member 1, the abutting driving member and thus the driving member bearing seat 2143 can be disassembled. In this way, the abutment driver does not need to be sunk underwater with the sinking body 21 following the immersed tube 8 , thereby avoiding the influence of the water flow on the abutment driver and prolonging the service life of the abutment driver. The driving member bearing base 2143 includes a first bearing plate 2143a and a second bearing plate 2143b, which are arranged at an angle, so that the abutting driving member can be clamped and fixed by the first bearing plate 2143a and the second bearing plate 2143b. In this way, the fixing structure of the abutting driver support base 2143 can be simplified, thereby reducing the manufacturing cost of the driving member bearing base 2143; meanwhile, the placement process of the abutting driving member can also be simplified, thereby reducing the labor intensity of the operator. Wherein, the first bearing plate 2143a and the second bearing plate 2143b may be provided in an integral structure to enhance the strength of the first bearing plate 2143a and the second bearing plate 2143b at the connection, thereby improving the stability of the bearing of the abutting driving member sex. At the same time, the first bearing plate 2143a and the second bearing plate 2143b are provided in an integral structure, so that the two can be integrally formed to improve the manufacturing efficiency of the driving member bearing seat 2143 . In addition, it should be noted that the present application is not limited to this, and in other embodiments, the driving member bearing seat 2143 and the abutting driving member may also be fixed by snaps or magnetic attraction.

In this way, the required accuracy of the moving distance when the sink assembly 2 and the sink tube 8 are initially approached to the guide member 1 can be reduced. 1 butt connection is all it takes, thereby further reducing the complexity of the butt connection between the sink assembly 2 and the guide member 1 . At the same time, since the sinking assembly 2 and the sinking tube 8 are connected, and the volume of the sinking tube 8 is relatively large, the mass is large, so that the sinking assembly 2 and the sinking tube 8 have greater inertia in the process of approaching the guide member 1 . The main body portion 211 is slidably arranged on the connecting frame 22, so that the sinking assembly 2 and the immersed tube 8 can stop moving in advance when they are close to a certain distance, so as to prevent the sinking assembly 2 and the immersed tube 8 from being in contact with each other due to their large inertia. When the guide member 1 is in contact, a large thrust force is generated, which causes damage to the guide member 1 , thereby improving the safety of the guide member 1 during butt connection with the sink assembly 2 .

This enables the driving assembly 5 to stably drive the main body portion 211 to approach the guide member 1 , and accurately move to the position where the guide member 1 and the main body portion 211 are pre-connected. At the same time, it can also reduce the possibility of the main body 211 colliding with the guide member 1 under the driving of the drive assembly 5 , thereby further improving the safety of the guide member 1 when it is connected to the sink assembly 2 . Of course, the present application is not limited to this. In other embodiments, the drive assembly 5 can also be a combination of a motor and a gear, that is, the output shaft of the motor is sleeved with a gear, and the main body 211 is connected with a rack, the rack and the gear meshed. The gear rack is driven to move by the motor driving the gear to rotate, so that the main body moves accordingly.

The connecting frame 22 is provided with a connecting frame connecting lug 22b. The connecting frame connecting lug 22b is inserted between the two cylinder body connecting ears 511 to be clamped. The tightening seat 53 passes through the cylinder body connecting ear 511 and the connecting frame connecting ear 22b, so that the hydraulic cylinder body 51 is connected to the connecting frame 22; the end of the piston rod 52 away from the hydraulic cylinder body 51 is provided with two oppositely arranged piston rod connecting ears 521, the main body 211 is provided with a sinking body connecting ear 2112, the sinking body connecting ear 2112 is inserted between the two piston rod connecting ears 521 to be clamped, and the second locking seat 54 passes through the piston rod connecting ear 521 and the sinking The main body connecting lugs 2112 connect the piston rod 52 to the main body part 211 .

It can be understood that the arrangement of the cylinder body connecting lugs 511 and the connecting frame connecting lugs 22b, the piston rod connecting lugs 521 and the sink body connecting lugs 2112 enables the connection between the hydraulic cylinder body 51 and the connecting frame 22 and the connection between the piston rod 52 and the main body 211 It is not necessary to provide a fixing structure on the hydraulic cylinder body 51, the connecting frame 22, the piston rod 52 and the main body part 211. By connecting the cylinder body connecting lugs 511 and the connecting frame connecting lugs 22b, the piston rod connecting lugs 521 and the sink body connecting lugs 2112 to connect.

The connection frame connecting lugs 22b are inserted between the two cylinder body connecting ears 511 to be clamped, which can increase the contact area between the connecting frame connecting lugs 22b and the cylinder body connecting lugs 511 and improve the stability of the connection between the hydraulic cylinder body 51 and the connecting frame 22 At the same time, the connecting bracket connecting lugs 22b can be clamped by the two cylinder body connecting lugs 511 to facilitate the insertion of the first locking seat 53 . Similarly, if the sink body connecting lug 2112 is inserted between the two piston rod connecting lugs 521 to be clamped, the contact area of the sink body connecting lug 2112 and the connecting lug 521 of the piston rod connecting lug 521 can be increased, thereby improving the connection between the piston rod 52 and the piston rod connecting lug 521. The stability of the connection of the main body portion 211 also enables the sinking body connecting lugs 2112 to be clamped by the two piston rod connecting lugs 521 to facilitate the insertion of the second locking seat 54 . In addition, the hydraulic cylinder body 51 is connected to the connecting frame 22 through the first locking seat 53 passing through the cylinder body connecting lug 511 and the connecting frame connecting lug 22b, and the second locking seat 54 passing through the piston rod connecting lug 521 and the sink body The connecting lugs 2112 realize that the piston rod 52 is connected to the main body part 211 , so that when the passing parts of the first locking seat 53 and the second locking seat 54 are circular, the hydraulic cylinder body 51 and the piston rod 52 can be respectively relative to the connecting frame 22 and the main body 211 rotate. At this time, the cylinder body and the piston rod 52 can be installed at an angle to the sliding direction of the main body portion 211 , and can also drive the main body portion 211 to approach or move away from the guide member 1 horizontally. In this way, the accuracy of the installation angle between the hydraulic cylinder body 51 and the piston rod 52 is reduced, so that the convenience of installation of the hydraulic cylinder body 51 and the piston rod 52 can be improved. Wherein, the connecting lugs 22b of the connecting frame and the connecting frame 22 can be fixed by welding, so as to ensure the stability of the connection between the hydraulic cylinder body 51 and the connecting frame 22, and simplify the connection process of the two. The connecting structure is used to fix the connecting ears 22b of the connecting frame, so that the strength of the connecting frame 22 can be ensured. Similarly, the sink body connecting ear 2112 and the main body portion 211 can also be fixed by welding.

The screw 533 passes through the first limit block 532 located outside the first limit groove 531a and is inserted into the cylinder body connecting ear 511; the second locking seat 54 includes a second insertion rod 541, a second limit block 542 and a third Two screws 543, the second insertion rod 541 passes through the piston rod connecting ear 521 and the sink body connecting ear 2112, the side surface of the second insertion rod 541 is provided with a second limiting groove 541a, and the second limiting block 542 abuts on the The surface of the piston rod connecting ear 521 is partially inserted into the second limiting groove 541a, and the second screw 543 passes through the second limiting block 542 outside the second limiting groove 541a and is inserted into the piston rod connecting ear 521.

It can be understood that by passing the first insertion rod 531 through the cylinder body connecting lug 511 and the connecting frame connecting lug 22b to realize the fixation of the two, the first locking seat 53 can prevent the cylinder body connecting lug 511 and the connecting frame connecting lug 22b from causing damage to the cylinder body connecting lug 511 and the connecting frame connecting lug 22b. Extrusion facilitates that the hydraulic cylinder body 51 can rotate relative to the connecting frame 22 . By inserting the first limiting block 532 into the first limiting groove 531a, the first insertion rod 531 can be prevented from being detached from the cylinder body connecting ears 511 and the connecting frame connecting ears 22b, so that the hydraulic cylinder body 51 and the connecting frame 22 can be further improved. connection stability. The arrangement of the first limiting groove 531a can simplify the connection structure between the first limiting block 532 and the first inserting rod 531 , and only the first inserting rod 531 is provided with a first limiting block 532 on the side surface of the first limiting block 532 . One limiting groove 531a is sufficient. The arrangement of the first screws 533 can ensure the stability of the fixation of the first limiting block 532 , and also simplifies the fixing process of the first limiting block 532 . At the same time, the first limiting block 532 can be detached from the cylinder body connecting ear 511, and then the first insertion rod 531 can be pulled out from the cylinder body connecting ear 511 and the connecting frame connecting ear 22b, so that the hydraulic cylinder body 51 and the connecting ear 22b can be pulled out. The connection frame 22 is detachable for easy maintenance and replacement.
