Description

A segment beam rapid demoulding transfer device and method

Technical Field

The present invention relates to the technical field of demoulding of segment beams, and in particular to a device and method for quickly demoulding and transferring segment beams.

Background technique

At present, in the casting construction of segmental beams, it is necessary to refer to the design drawings to number the beam structure. The segment block located at the top of the middle pier is block 0#, and the bracket method is used for cast-in-place construction at the construction site; the segments extending to both sides are prefabricated segments, and the segments adjacent to the position of block 0# are block 1#, which are numbered 2#, 3#, etc. In the prefabrication of segments, the 1# segment block is prefabricated first, that is, steel end molds are set on both sides of the 1# segment, and then the 1# segment is used as one side end mold and the other side as steel end mold, and so on, so as to achieve the purpose of multi-segment prefabrication. After the prefabrication of the segmental beam is completed, the beam segment needs to be hoisted from the prefabrication area to the beam storage area. When the segment is separated, one side is lifted first, and then dropped when a gap appears at the bottom of the beam segment, so that the beam segment is separated. However, this separation method is very likely to cause problems such as collision of the structural edges and corners of the segmental beam, especially the damage of the shear key, and it needs to be lifted and dropped twice, which is more troublesome.

As shown in Fig. 1, Fig. 2 and Fig. 3, a segment beam rapid demoulding and transfer system of the present invention comprises a longitudinal array guide mold device 200, a transverse guide frame 300, an adjustable sliding seat 500, a hoisting and pulling device 400 and a material taking and releasing device. The longitudinal array guide mold device 200 is installed at the lower end of the multi-segment arc bottom mold 100, and a transverse guide frame 300 is arranged above the multi-segment arc bottom mold 100. The transverse guide frame 300 spans the longitudinal array guide mold device 200, and the lower end of the transverse guide frame 300 is fixedly installed on the ground. A transverse rail 800 is installed on the transverse guide frame 300, and the adjustable sliding seat 500 is installed on the transverse rail 800. The material taking and releasing device is installed at the lower end of the adjustable sliding seat 500, and the first steel wire rope 403 and the second steel wire rope 409 wound on the hoisting and pulling device 400 are respectively stretched on the lateral ends of the adjustable sliding seat 500. The working principle and advantages of the embodiment of the present invention are as follows: a plurality of segmented beams 700 are prefabricated on a mold, and then other molds except the multi-segmented arc bottom mold 100 are removed; then the longitudinal array guide mold device 200 is operated, and since the bottom surface of the multi-segmented arc bottom mold 100 is an arc surface, and the multi-segmented arc bottom mold 100 is formed by sequentially splicing a plurality of segments, thus, under the drive of the longitudinal array guide mold device 200, the multi-segmented arc bottom mold 100 is gradually arrayed, and since the arc bottom 701 at the lower end of the segmented beam 700 is in contact with the multi-segmented arc bottom mold 100, during the process of the multi-segmented arc bottom mold 100 being arrayed in one direction, under the horizontal component of the friction force between the multi-segmented arc bottom mold 100 and the arc bottom 701, the plurality of segmented beams 700 are arrayed along with the array of the multi-segmented arc bottom mold 100. Until all the segment beams 700 are moved to the material discharging device, the hoisting and pulling device 400 is controlled to move, so that it drives the adjustable sliding seat 500 to move along the transverse track 800, thereby realizing the transportation of the segment beam 700. When the segment beam 700 is transported to the storage area, the material discharging device puts down the segment beam 700, thereby completing the entire process operation. In summary, the embodiment of the present invention can realize the rapid demoulding of the segment beam 700 after prefabrication, avoid collision and damage between the segment beams 700, and improve the demoulding and transportation efficiency.

As shown in FIG4 , the multi-segment arc bottom mold 100 includes a plurality of arc bottom mold bodies 101 longitudinally spliced in sequence, and a support seat 102 is installed at the lower end of each arc bottom mold body 101. Among them, the longitudinal array guide mold device 200 includes an array drive mechanism, a plurality of sliding seats 201 and two longitudinal rails 203, each sliding seat 201 is fixedly installed on the corresponding support seat 102, and two U-shaped slide grooves 202 are constructed side by side at the lower end of the sliding seat 201. The two longitudinal rails 203 of this embodiment are arranged side by side below the multi-segment arc bottom mold 100, each U-shaped slide groove 202 is slidably assembled on the corresponding longitudinal rail 203, and each sliding seat 201 is drivingly connected to the array drive mechanism. The working principle and advantages of this embodiment are: when the array drive mechanism is driven to array the multi-segment arc bottom mold 100, the array direction of the multi-segment arc bottom mold 100 is the direction indicated by the arrow in Figure 5, so that during the array process, friction is generated between the arc bottom mold body 101 and the segment beam 700 thereon, and the horizontal component of the friction makes the segment beam 700 move with the arc bottom mold body 101, so as to achieve the purpose of disengaging the segment beam 700 array. Moreover, during the array process, the sliding seat 201 moves along the longitudinal track 203 through the U-shaped slide groove 202, thereby reducing the friction between the sliding seat 201 and the longitudinal track 203, and avoiding the sliding seat 201 from disengaging the longitudinal track 203.

As shown in Fig. 4 and Fig. 5, the array drive mechanism includes a fixed seat 207 and two transmission screws 204, and the two transmission screws 204 are respectively arranged on both sides of the multi-segment arc bottom mold 100. Among them, the fixed seat 207 is fixedly installed on the ground, one end of the two transmission screws 204 is rotatably connected to the fixed seat 207, and the other end of the two transmission screws 204 is respectively equipped with a transmission wheel 206. This embodiment achieves the purpose of synchronous rotation of the two transmission screws 204 by driving the two transmission wheels 206 to rotate synchronously. Two screw transmission clutch mechanisms 900 are symmetrically installed on both sides of each sliding seat 201, and each of the screw transmission clutch mechanisms 900 is threadedly connected to the corresponding transmission screw 204. The specific structure of the transmission screw 204 of this embodiment is as shown in FIG6 , the transmission screw 204 includes a screw body, and a plurality of transmission threads 205 are spaced apart on the screw body, and the pitch of these transmission threads 205 increases along the axial direction of the screw body toward the fixed seat 207 (i.e., toward the array direction), and each screw transmission clutch mechanism 900 is connected to the screw body through the corresponding transmission thread 205. The working principle and advantage of this embodiment are: when multiple arc bottom mold bodies 101 are synchronously arrayed, two transmission screws 204 are driven to rotate synchronously, and during the synchronous rotation of the two transmission screws 204, due to the special setting of the pitch of the transmission thread 205 on the screw body, the arc bottom mold body 101 located at the front moves faster with the corresponding sliding seat 201, and the arc bottom mold body 101 located at the rear moves slower with the corresponding sliding seat 201, thereby realizing that multiple arc bottom mold bodies 101 move in a direction 5 , the arc bottom mold body 101 is moved in the opposite direction of the arrow in FIG. 5 , so that the arc bottom mold body 101 and the arc bottom 701 of the segmented beam 700 are quickly separated, thereby avoiding friction during the separation of the arc bottom mold body 101 and the segmented beam 700, which affects the return efficiency. The present embodiment can also independently arrange multiple arc-shaped bottom mold bodies 101 in an array in one direction in sequence. Specifically, the two lead screw transmission clutch mechanisms 900 on the sliding seat 201 closest to the fixed seat 207 are controlled to be in an engaged state, and the lead screw transmission clutch mechanisms 900 on the other sliding seats 201 are in a disengaged state, driving the two transmission lead screws 204 to rotate synchronously in the positive direction. Under the action of the transmission lead screw 204 and the lead screw transmission clutch mechanisms 900 in the engaged state, the sliding seat 201 closest to the fixed seat 207 drives the arc-shaped bottom mold body 101 and the segment beam 700 to move toward the fixed seat 207, and the other sliding seats 201 and The corresponding arc-shaped bottom mold body 101 does not move; when it moves into place, the two screw transmission clutch mechanisms 900 in the engaged state are converted to the disengaged state, and the screw transmission clutch mechanism 900 on the sliding seat 201 close to the fixed seat 207 and not arrayed is converted to the engaged state, and the screw transmission clutch mechanisms 900 on other sliding seats 201 are all in the disengaged state, and the two transmission screws 204 are driven to rotate synchronously in the positive direction again, so that the corresponding sliding seat 201 and the arc-shaped bottom mold body 101 and the segment beam 700 thereon move toward the fixed seat 207; this operation is repeated until the array of all sliding seats 201 is completed.

As shown in Fig. 7, Fig. 8, Fig. 9 and Fig. 10, the lead screw transmission clutch mechanism 900 comprises a first assembly seat body 901 and a second assembly seat body 902 which are interlocked with each other, and a connecting edge 903 is respectively constructed on the side of the first assembly seat body 901 and the second assembly seat body 902 close to the sliding seat 201, and the two connecting edges 903 are detachably connected with the corresponding sliding seat 201 by bolts. In this embodiment, a plurality of connecting holes 904 are respectively opened on the first assembly seat body 901 and the second assembly seat body 902, and the connecting holes 904 on the first assembly seat body 901 and the second assembly seat body 902 are arranged one by one, and then the first assembly seat body 901 and the second assembly seat body 902 are connected and fixed by a plurality of connecting bolts. In this embodiment, an internally threaded guide sleeve 905 is rotatably mounted on the first assembly seat body 901, and a hydraulic limiting component is installed on the second assembly seat body 902 at a position corresponding to the internally threaded guide sleeve 905. A first toothed disc 907 and a second toothed disc 917 are respectively constructed at the ends where the internally threaded guide sleeve 905 and the hydraulic limiting component are close to each other. A plurality of first engaging teeth 908 are constructed on an end face of the first toothed disc 907 close to the second toothed disc 917, and these first engaging teeth 908 are uniformly arranged along the circumference of the first toothed disc 907. A plurality of second engaging teeth 918 are constructed on an end face of the second toothed disc 917 close to the first toothed disc 907, and these second engaging teeth 918 are uniformly arranged along the circumference of the second toothed disc 917. A limiting flange 906 is constructed at the other end of the internally threaded guide sleeve 905. The hydraulic limiting member of this embodiment includes a hydraulic sleeve 909, a movable sleeve 911 and a sleeve-shaped piston 912, wherein the hydraulic sleeve 909 is constructed on the second assembly seat body 902, the hydraulic sleeve 909 has an annular hydraulic cavity, and the hydraulic sleeve 909 has a conducting channel 910 for the transmission screw 204 to pass through, and the conducting channel 910 is aligned with the threaded channel of the internal threaded guide sleeve 905. The second toothed disc 917 of this embodiment is constructed at one end of the movable sleeve 911, and the sleeve-shaped piston 912 is constructed at the other end of the movable sleeve 911. The sleeve-shaped piston 912 extends into the hydraulic cavity, and the radial cross-sections of the outer circumference of the sleeve-shaped piston 912 and the outer circumference of the hydraulic cavity are mutually adapted regular polygons to prevent relative rotation between the sleeve-shaped piston 912 and the hydraulic sleeve 909. The hydraulic chamber of this embodiment is divided into a first chamber 913 and a second chamber 914 by a sleeve-shaped piston 912, and a first hydraulic joint 915 and a second hydraulic joint 916 are constructed on the hydraulic sleeve 909, and the first hydraulic joint 915 and the second hydraulic joint 916 are respectively connected to the first chamber 913 and the second chamber 914. The working principle and advantage of this embodiment are: when it is necessary to drive the sliding seat 201 to move, the hydraulic oil is controlled to drive the sleeve-shaped piston 912 to drive the second toothed disc 917 to move toward the first toothed disc 907 until the first meshing teeth 908 on the first toothed disc 907 and the second meshing teeth 918 on the second toothed disc 917 mesh with each other, so that in the process of driving the transmission screw 204 to rotate, the internal threaded guide sleeve 905 does not have a relative displacement with the sliding seat 201 under the restriction of the hydraulic restriction member, and then under the transmission of the internal threaded guide sleeve 905 and the transmission screw 204, the sliding seat 201 moves along the axial direction of the transmission screw 204. When the driving screw 204 is driven to rotate, and the sliding seat 201 does not need to move, the sleeve-shaped piston 912 is driven by hydraulic oil to drive the second toothed disc 917 to move away from the first toothed disc 907 until the first meshing teeth 908 on the first toothed disc 907 and the second meshing teeth 918 on the second toothed disc 917 are disengaged from each other. In this way, during the rotation of the driving screw 204, the internal thread guide sleeve 905 rotates relative to the sliding seat 201 along with the driving screw 204, that is, the internal thread guide sleeve 905 rotates idly in the sliding seat 201, thereby achieving the purpose of preventing the sliding seat 201 from rotating when the driving screw 204 rotates.

The lower end of each lifting cylinder 601 is connected to a transfer seat 602, and these transfer seats 602 are all connected to the corresponding parts of the end support plate 603. When the segmented beam 700 is moved and arrayed to the material loading and unloading device, the lower end faces of each wing of the segmented beam 700 are close to or in contact with the upper end faces of the corresponding end support plates 603 in the vertical direction. In this embodiment, a side limiting plate 604 is provided on one side of the end support plate 603 close to the segment beam 700, and a plurality of connecting columns 608 are constructed on the side limiting plate 604 at intervals along the width direction of the transverse rail 800. A connecting plate 606 is constructed at the lower end of the end support plate 603, and each connecting column 608 passes through a corresponding position of the connecting plate 606, and a locking nut 609 is threadedly connected to the connecting column 608, that is, two locking nuts 609 are threadedly connected to each connecting column 608, and the two locking nuts 609 are screwed on two opposite sides of the side limiting plate 604. The working principle and advantage of this embodiment are as follows: when the segment beam 700 is arrayed to the position of the material taking and unloading device by the longitudinal array guide mold device 200, the two end support plates 603 support the two wings of the segment beam 700, and the two side limiting plates 604 limit the segment beam 700 therebetween, and then when the segment beam 700 is transported, the two end support plates 603 bear the gravity of the segment beam 700 and carry the segment beam 700 to move, and the two side limiting plates 604 limit the deflection or swing of the segment beam 700, so that the segment beam 700 can be smoothly transported. When arriving at the storage area, all the lifting cylinders 601 are controlled to move synchronously so that it is placed in the storage area; then, the drive motor 503 is controlled to drive the transmission rod 504 to rotate forward, so that the first sliding seat body 501 and the second sliding seat body 502 drive the two material-limiting lifting mechanisms 600 to move away from each other until the distance between the two material-limiting lifting mechanisms 600 is greater than the width of the segment beam 700, and then all the lifting cylinders 601 are controlled to drive the end support plate 603 and the side limit plate 604 to move upward until the end support plate 603 and the side limit plate 604 are higher than the upper end surface of the segment beam 700, finally, the winch pulling device 400 is controlled to gradually return the adjustable sliding seat 500 to its original position, and before, during or after the return, the drive motor 503 is controlled to drive the transmission rod 504 to rotate in the opposite direction, so that the first sliding seat body 501 and the second sliding seat body 502 drive the two material-limiting lifting mechanisms 600 to move closer to each other to a predetermined distance. In this embodiment, the distance between the side limiting plate 604 and the end support plate 603 can be adjusted, that is, all the locking nuts 609 can be loosened to make the connecting column 608 in an adjustable state, and then the distance between the side limiting plate 604 and the end support plate 603 can be adjusted. After the adjustment is completed, the locking nuts 609 are tightened to restrict the segment beams 700 of different types and different waists (widths). In order to avoid the situation in which the corresponding end faces or sides of the segment beams 700 collide with the end support plate 603 or the side limiting plate 604 when the segment beams 700 are driven to the material loading and unloading device and cause damage, the measures taken in this embodiment are that the end guide edge 605 and the end guide head 607 are respectively constructed at the leading end of the end support plate 603 and the side limiting plate 604, and the end guide edge 605 is bent downward, and the end guide head 607 is bent toward the connecting plate 606.

As shown in Fig. 3 and Fig. 11, the hoisting and pulling device 400 includes a hoist 401, a first guide wheel 402, a second guide wheel 404, a third guide wheel 407, a fourth guide wheel 408, a hydraulic cylinder 405 and a tension wheel 406. The hoist 401 is installed on the ground at one end of the transverse guide frame 300, the first guide wheel 402 and the second guide wheel 404 are respectively installed at both ends of the length direction of the upper end of the transverse guide frame 300, the third guide wheel 407 and the fourth guide wheel 408 are respectively installed at both ends of the length direction of the lower end of the transverse guide frame 300, one end of the first steel wire rope 403 is connected to the first sliding seat 501 through the first guide wheel 402, and one end of the second steel wire rope 409 is connected to the second sliding seat 502 through the fourth guide wheel 408, the third guide wheel 407 and the second guide wheel 404. Moreover, in this embodiment, when the winch 401 rotates forward, the first steel wire rope 403 is unwound and the second steel wire rope 409 is reeled in, so that the adjustable sliding seat 500 drives the material picking and unloading device to move along the transverse track 800 toward the storage area, thereby achieving the purpose of transporting the segment beam 700; when the winch 401 rotates reversely, the first steel wire rope 403 is reeled in and the second steel wire rope 409 is unwound, so that the adjustable sliding seat 500 drives the material picking and unloading device to move along the transverse track 800 away from the storage area, thereby achieving the purpose of the adjustable sliding seat 500 driving the material picking and unloading device to return to its original position. The hydraulic cylinder 405 of this embodiment is installed on the transverse guide frame 300, and the hydraulic cylinder 405 is located between the second guide wheel 404 and the third guide wheel 407. A pressure sensor is installed on the cylinder rod of the hydraulic cylinder 405. The tensioning wheel 406 is rotatably installed on the end of the cylinder rod of the hydraulic cylinder 405, and the second steel wire rope 409 is in a tensioned state due to the action of the tensioning wheel 406. When the driving motor 503 drives the transmission rod 504 to rotate forward, the second sliding seat body 502 moves away from the first sliding seat body 501. At this time, the first sliding seat body 501 does not move on the transverse track 800. In this way, the second steel wire rope 409 will become loose. When the pressure sensor detects that the pressure becomes smaller, the cylinder rod of the hydraulic cylinder 405 will gradually extend out of the cylinder body, and the tensioning wheel 406 will always maintain a predetermined tensioning force to tension the second steel wire rope 409, thereby preventing the second steel wire rope 409 from detaching from the second guide wheel 404 or the third guide wheel 407 or the fourth guide wheel 408. When the driving motor 503 drives the transmission rod 504 to rotate forward, the second sliding seat 502 moves toward the first sliding seat 501. When the pressure sensor detects that the pressure exceeds the predetermined value, the cylinder rod of the hydraulic cylinder 405 will gradually shrink back to the cylinder body, so that the tensioning wheel 406 always maintains the predetermined tension to tension the second steel wire rope 409, so as to avoid excessive tension of the second steel wire rope 409 and excessive pulling of the corresponding components, thereby preventing the components from being damaged. In addition, the second steel wire rope 409 crosses the lower part of the longitudinal array guide mold device 200 and the entire casting mold between the third guide wheel 407 and the fourth guide wheel 408, that is, a separate channel is provided under the longitudinal array guide mold device 200 and the entire casting mold for unwinding and rewinding the second steel wire rope 409, thereby preventing the second steel wire rope 409 from interfering with the array or return of the longitudinal array guide mold device 200 and the multi-segment arc bottom mold 100.

Step 3, stop the longitudinal array guide mold device 200 and remove the end molds between adjacent segment beams 700;

Step 4, continue to control the longitudinal array guide mold device 200 to move until all the segment beams 700 are moved to the position of the material taking and placing device;

Step 5, control the longitudinal array guide mold device 200 to return to its original position, and then control the hoisting and pulling device 400 to move, so that it drives the adjustable sliding seat 500 to drive the material taking and placing device to move along the transverse track 800;

Step 6: When the material picking and placing device moves to the storage area, the adjustable sliding seat 500 and the material picking and placing device are controlled to move so that all the segment beams 700 on the material picking and placing device are put down synchronously;

Step seven, sequentially controlling the material taking and releasing device, the adjustable sliding seat 500 and the hoisting and pulling device 400 to return to their original positions, so that each device returns to its initial position.
