A clamping device 100 and a work vehicle 200 for a track beam 300 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, a working vehicle 200 for a track beam 300 includes a vehicle body 210 and a clamping device 100 according to an embodiment of the present invention. The vehicle body 210 may travel on the track beam 300 so that the working vehicle 200 may move along the track beam 300 to a position where work such as inspection and lifting is required. The clamping device 100 is mounted on the vehicle body 210, and the clamping device 100 can clamp the track beam 300 to fix the vehicle body 210 on the track beam 300 and limit the vehicle body 210 to walk, so as to prevent the vehicle body 210 from moving or turning over during the operation process to influence the normal operation, and even cause safety accidents.
Referring to fig. 2, a clamping device 100 according to an embodiment of the present invention may include a clamping body 20.
Specifically, the clamp body 20 may include: a clamping assembly 40 and a drive assembly 50. The clamping assembly 40 comprises a first clamping piece 41 and a second clamping piece 42, and the driving assembly 50 can be used for driving the first clamping piece 41 to rotate and the second clamping piece 42 to rotate, so that the first clamping piece 41 and the second clamping piece 42 can clamp the track beam 300, the locking of the vehicle body 210 and the track beam 300 is realized, and the vehicle body 210 is prevented from moving relative to the track beam 300; or the first and second clamps 41 and 42 can be released from the track beam 300 so that the vehicle body 210 can be moved relative to the track beam 300 to move the work vehicle 200 to an optimum position for performing work.
In the related art, the clamping device occupies a large space, which is disadvantageous for installation and layout on a work vehicle. For example, in some related technologies, the clamping device clamps the track beam through the movement of the connecting rod structure, during the movement of the connecting rod structure, a plurality of motions such as swinging and moving are required to be matched, the track beam moves in a plurality of dimensions, and a guide structure is required to guide the connecting structure, so that the structure is complex, the required working space is large, and the occupied space is large.
In the present invention, the clamping assembly 40 clamps or releases the track beam 300 only by rotating the first clamping member 41 and the second clamping member 42, the clamping device 100 has a simple structure, occupies a small space, and only includes the action of rotating, so that the required working space is small, the space is saved, and the installation and layout of the clamping device 100 on the working vehicle 200 are facilitated. In addition, the process of clamping the track beam 300 by the clamping device 100 is not limited by the structure of the track beam 300, that is, by changing the rotation angle of the first clamping member 41 and the second clamping member 42, the clamping device 100 can clamp the track beam 300 with any height and any width, so as to meet the requirements of more working conditions.
According to the clamping device 100 provided by the embodiment of the invention, the clamping assembly 40 clamps and releases the track beam 300 through the rotation of the first clamping piece 41 and the second clamping piece 42, the structure of the clamping device 100 is simple, the required working space is small, the space is saved, and the connection and the layout with the vehicle body 210 are convenient.
The working vehicle 200 for the track beam 300 according to the embodiment of the present invention includes the clamping device 100 according to the embodiment of the present invention, and since the clamping device 100 according to the embodiment of the present invention has the above-mentioned advantageous technical effects, the working vehicle 200 for the track beam 300 according to the embodiment of the present invention clamps and releases the track beam 300 by the clamping assembly 40 through the rotation of the first clamping member 41 and the second clamping member 42, the structure of the clamping device 100 is simple, the required working space is small, the space is more saved, and the connection and layout of the clamping device 100 and the vehicle body 210 are easier.
According to some embodiments of the invention, the axis of rotation of the first clamp 41 and the axis of rotation of the second clamp 42 coincide. Therefore, the structure of the clamping body 20 is simpler and more symmetrical, the positions of the first clamping piece 41 and the second clamping piece 42 are more compact in the direction perpendicular to the rotation axis of the first clamping piece 41 and the second clamping piece 42, which is beneficial to further reducing the occupied space, and when the first clamping piece 41 and the second clamping piece 42 clamp the track beam 300, the clamping force applied to the track beam 300 is more symmetrical, which is beneficial to improving the clamping effect.
According to some embodiments of the present invention, as shown in fig. 2, the first clamping member 41 may include a first driving rod 412 and a first clamping portion 411, the first clamping portion 411 may be disposed at one end of the first driving rod 412, and the other end of the first driving rod 412 may be in driving connection with the driving assembly 50. The second clamping member 42 may include a second transmission rod 422 and a second clamping portion 421, the second clamping portion 421 may be disposed at one end of the second transmission rod 422, and the other end of the second transmission rod 422 may be in transmission connection with the driving assembly 50.
Thus, the driving assembly 50 can drive the first driving rod 412 and the second driving rod 422 to rotate. The first driving rod 412 rotates to drive the first holding portion 411 to rotate, and the second driving rod 422 rotates to drive the second holding portion 421 to rotate. The first clamping portion 411 and the second clamping portion 421 can clamp the track beam 300 when rotating and relatively approaching, and the first clamping portion 411 and the second clamping portion 421 can release the track beam 300 when rotating and relatively departing, so that the first clamping member 41 and the second clamping member 42 have simple structures, and the movement of clamping and releasing the track beam 300 is simpler.
The power of the driving assembly 50 is transmitted to the first clamping portion 411 and the second clamping portion 421 through the first driving rod 412 and the second driving rod 422, and the first driving rod 412 and the second driving rod 422 can increase the moment arm for driving the first clamping portion 411 and the second clamping portion 421 to rotate, so that the clamping reliability of the first clamping portion 411 and the second clamping portion 421 to the track beam 300 is improved.
According to some embodiments of the present invention, as shown in fig. 2, the first grip 411 may be located at one end of the first transmission lever 412, the second grip 421 may be located at one end of the second transmission lever 422, the driving assembly 50 may be located at the other ends of the first transmission lever 412 and the second transmission lever 422, and the first transmission lever 412 and the second transmission lever 422 are rotatably coupled at a position between the one end and the other end thereof.
Thus, when the other end of the first driving lever 412 and the other end of the second driving lever 422 approach each other by the driving of the driving assembly 50, the first driving lever 412 and the second driving lever 422 rotate to cause one end of the first driving lever 412 and one end of the second driving lever 422 to approach each other, and further cause the first clamping portion 411 and the second clamping portion 421 to approach each other to clamp the track beam 300; when the other end of the first driving lever 412 and the other end of the second driving lever 422 are moved away from each other by the driving of the driving assembly 50, the first driving lever 412 and the second driving lever 422 are rotated to move one end of the first driving lever 412 and one end of the second driving lever 422 away from each other, and thus move the first clamping portion 411 and the second clamping portion 421 away from each other to release the track beam 300. The clamping device 100 has a simpler work process and a simpler structure for clamping and releasing the track beam 300.
In some embodiments, continuing to refer to fig. 2, clamping device 100 may further include a mount 10, mount 10 being used to mount clamping body 20. Specifically, the mounting seat 10 is mounted on the vehicle body 210, and the driving assembly 50 can be connected to the mounting seat 10 to achieve connection with the vehicle body 210, so that the mounting positions required to be arranged on the vehicle body 210 can be reduced, the number of openings of the vehicle body 210 is reduced, and the structural reliability of the vehicle body 210 is improved.
In some embodiments, referring to fig. 2, the driving assembly 50 may include a first driving member 51 and a second driving member 52, the first clamping member 41 is connected to the first driving member 51 to rotate under the driving of the first driving member 51, and the second clamping member 42 is connected to the second driving member 52 to rotate under the driving of the second driving member 52. In other words, the first and second clamping members 41 and 42 are driven individually, whereby the rotation of the first and second clamping members 41 and 42 does not affect each other, and when one of them is stuck or damaged, the other one can work normally to clamp or unclamp the track beam 300. In addition, the structure of the driving assembly 50 can be simplified by driving alone, the driving force of the driving assembly 50 to the first clamping piece 41 and the second clamping piece 42 is increased, and the clamping effect of the track beam 300 is further increased.
In some embodiments, as shown in fig. 2, the clamping assembly 40 may further include a rotating shaft 43, the first clamping member 41 may be rotatably connected with the rotating shaft 43, and the second clamping member 41 may also be rotatably connected with the rotating shaft 43. In other words, the first clamping member 41 and the second clamping member 42 share the same rotating shaft 43, the axes of the rotating shaft 43, namely the rotating axis of the first clamping member 41 and the rotating axis of the second clamping member 42, achieve the coincidence of the rotating axis of the first clamping member 41 and the rotating axis of the second clamping member 42, no multiple rotating shaft structures need to be arranged, the structure of the clamping device 100 is simplified, and the coincidence of the rotating axes of the first clamping member 41 and the second clamping member 42 is easier to achieve.
In the embodiment including the mounting seat 10, as shown in fig. 2 and 6, the first driving member 51 and the second driving member 52 may be respectively disposed on two sides of the mounting seat 10 away from each other, so as to prevent the first driving member 51 and the second driving member 52 from position interference during operation. For example, in the embodiment shown in fig. 2, the first driving member 51 and the second driving member 52 are respectively disposed on two sides of the mounting seat 10 facing away from each other in the horizontal direction, which not only can prevent the first driving member 51 and the second driving member 52 from interfering with each other in position, but also can reduce the height of the clamping device 100 in the vertical direction, so as to make the structure more compact.
In some embodiments, the first drive member 51 may be a cylinder and the second drive member 52 may be a cylinder. The movement process of the oil cylinder is stable, the stroke of the oil cylinder is controllable, the linear movement of the oil cylinder is converted into the rotary movement of the first clamping piece 41 and the second clamping piece 42, the stroke of the first clamping piece 41 and the stroke of the second clamping piece 42 are controllable, the clamping and the loosening of the track beam 300 are easier to control, and the control of the clamping device 100 is simpler.
In some embodiments of the present invention, as shown in fig. 2, one end of the first driving member 51 may be hinged to the mounting base 10, and the other end of the first driving member 51 may be hinged to the first clamping member 41, so that during the process that the first driving member 51 drives the first clamping member 41 to rotate, the first driving member 51 may rotate relative to the mounting base 10 and the first clamping member 41 to adapt to the rotation of the first clamping member 41, so as to prevent the first clamping member 41 from being jammed, and the first clamping member 41 rotates more smoothly.
In some embodiments of the present invention, as shown in fig. 2, one end of the second driving member 52 may be hinged to the mounting seat 10, and the other end of the second driving member 52 may be hinged to the second clamping member 42, so that during the process of the second driving member 52 driving the second clamping member 42 to rotate, the second driving member 52 may rotate relative to the mounting seat 10 and the second clamping member 42 to adapt to the rotation of the second clamping member 42, so as to prevent the second clamping member 42 from being jammed, and the second clamping member 42 rotates more smoothly.
In some embodiments, as shown in fig. 2 to 5, the first clamping portion 411 may be in surface-to-surface contact with the track beam 300 to increase the matching area of the first clamping portion 411 and the track beam 300, and improve the clamping effect.
In some embodiments, as shown in fig. 2 to 5, the second clamping portion 421 may be in surface-to-surface contact with the track beam 300 to increase a fitting area of the second clamping portion 421 and the track beam 300, so as to improve a clamping effect.
Further, as shown in fig. 2, the first clamping portion 411 may be a clamping plate, and the second clamping portion 421 may be a clamping plate, which includes a polyurethane layer. The polyurethane layer has good vibration damping and buffering effects, so that damage caused by overlarge impact force when the first clamping portion 411 and the second clamping portion 421 collide or contact with the track beam 300 is prevented.
Alternatively, a plate body of the clamping plate facing the rail beam 300 may be formed as a polyurethane layer, that is, the polyurethane layer is in direct contact with the rail beam 300, and vibration damping and buffering effects are better.
According to some embodiments of the present invention, as shown in fig. 2-10, the clamping device 100 may further include a body driving assembly 60, and the body driving assembly 60 may be used to drive the clamping body 20 to move relative to the vehicle body 210 so that the height of the lowest point of the clamping body 20 in the vertical direction is variable.
When the vehicle body 210 does not need to be fixed, the clamping body 20 can move, so that the lowest point of the clamping body 20 is raised in the height of the vertical direction, so as to avoid the structure below the vehicle body 210, and prevent the clamping device 100 from influencing the normal running of the working vehicle 200. When the vehicle body 210 needs to be fixed, the clamping body 20 may move such that the lowest point of the clamping body 20 is lowered in height in the vertical direction, so that the first and second clamping members 41 and 42 may clamp the rail beam 300. Or the clamping body 20 may be moved to accommodate different rail beam 300 heights to select a more optimal clamping position.
It should be noted that "the clamping body 20 moves relative to the vehicle body 210" is broadly understood herein, that is, the clamping body 20 can move relative to the vehicle body 210 through at least one of vertical movement, rotation, extension, retraction, folding, unfolding, and the like.
According to a further embodiment of the present invention, the body driving assembly 60 may be mounted to the vehicle body 210, and the body driving assembly 60 may be used to drive the clamping body 20 to move or rotate between the storage position and the working position. As shown in fig. 1 to 5, when the clamping body 20 is in the working position, the lowest point of the clamping body 20 is lower than the highest point of the track beam 300, so that the first clamping piece 41 and the second clamping piece 42 can rotate to clamp the track beam 300; as shown in fig. 6 to 10, when the clamping body 20 is at the storage position, the lowest point of the clamping body 20 is higher than the highest point of the track beam 300 so as to avoid the track beam 300, so as to prevent the clamping body 20 and the track beam 300 from interfering with each other to affect the running or turning of the working vehicle 200, and also prevent the clamping body 20 from affecting the operation of other devices on the track beam 300, and the structural design is more reasonable.
In embodiments including mount 10, as shown in fig. 2 and 6, mount 10 may include: a base 11 and a mounting 12. The base 11 may be mounted to the vehicle body 210, for example, by welding, fastening, and the like. The clamping body 20 may be connected to a mounting 12, the mounting 12 may be hinged to the base 11, and the mounting 12 may be rotatable relative to the base 11 about a rotation axis extending in a horizontal direction. The body drive assembly 60 may drive the clamping body 20 and the mount 12 to rotate together about the rotational axis of the mount 12 relative to the base 11 such that the lowest point of the clamping body 20 changes in height in the vertical direction and the highest point of the clamping body 20 does not change in height in the vertical direction. Therefore, the space in the vertical direction required to achieve the lowest point height variation of the clamp body 20 is small, reducing the occupied space. The clamp body 20 itself does not need to be provided with a telescopic or folding structure, for example, in the embodiment where the first clamping member 41 includes the first transmission rod 412 and the second clamping member 42 includes the second transmission rod 422, the first transmission rod 412 and the second transmission rod 422 may be complete rod structures, and the structure strength is higher, and is more firm and reliable.
According to an embodiment of the present invention, as shown in fig. 2 and 6, the body driving unit 60 is axially retractable, one axial end of the body driving unit 60 is mounted to the vehicle body 210, and the other axial end of the body driving unit 60 is connected to the clamping body 20. When the body drive assembly 60 is shortened, the clamping body 20 and the mounting 12 can be rotated in the first direction about the rotational axis of the mounting 12, so that the clamping body 20 can be rotated from the working position to the storage position even if the lowest point of the clamping body 20 rises in height in the vertical direction. When the body drive assembly 60 is extended, the clamping body 20 and the mounting member 12 can be rotated about the rotational axis of the mounting member 12 in a second direction, which is opposite to the first direction, so that the clamping body 20 can be rotated from the storage position to the operating position even if the height of the lowest point of the clamping body 20 in the vertical direction is lowered.
In addition, as shown in fig. 4 and 9, since the included angle between the body driving assembly 60 and the clamping body 20 and the included angle between the body driving assembly 60 and the horizontal direction change during the rotation of the clamping body 20 relative to the base 11 under the driving of the body driving assembly 60, the body driving assembly 60 can be hinged to the vehicle body 210, and the body driving assembly 60 can be rotatably connected to the clamping body 20 to adapt to the change of the angle, so as to prevent the clamping body 20 from being locked relative to the rotation of the base 11.
According to some embodiments of the present invention, as shown in fig. 4 and 9, the body driving assembly 60 may be connected to the clamping assembly 40 to drive the clamping body 20 to move, on one hand, the moment arm for the body driving assembly 60 to drive the clamping body 20 to rotate may be increased, and the required driving force may be reduced, on the other hand, the structure of the clamping assembly 40 is simpler, and the clamping assembly is easier to assemble with the body driving assembly 60, and the structural design is more reasonable.
To improve the uniformity of the force applied to the clamping body 20 during the movement or rotation of the clamping body 20 driven by the body driving assembly 60, the body driving assembly 60 may be connected to the first clamping member 41 and the second clamping member 42.
Specifically, as shown in fig. 7, 8 and 10, the first clamping member 41 may be provided with a first connecting member 413, the first connecting member 413 having a first shaft hole, and the second clamping member 42 may be provided with a second connecting member 423, the second connecting member 423 having a second shaft hole. The other axial end of the body driving assembly 60 may be provided with a mounting shaft 61, and the mounting shaft 61 is rotatably inserted into the first shaft hole and the second shaft hole to realize the rotatable connection of the mounting shaft 61 with the first clamping member 41 and the second clamping member 42.
The hinge axis of the body drive assembly 60 to the vehicle body 210 and the axis of the mounting shaft 61 may both be parallel to the rotational axis of the mount 12, and the rotational axis of the first clamp 41 and the rotational axis of the second clamp 42 may both be perpendicular to the rotational axis of the mount 12. Thus, when the body driving assembly 60 drives the clamping body 20 and the mounting member 12 to rotate around the rotation axis of the mounting member 12, the force applied to the clamping body 20 by the body driving assembly 60 will not rotate the first clamping member 41 around the rotation axis of the first clamping member 41 or the second clamping member 42 around the rotation axis of the second clamping member 42, and the first clamping member 41 and the second clamping member 42 are prevented from rotating relatively to each other to influence the body driving assembly 60 to drive the clamping body 20 and the mounting member 12 to rotate.
Since the first and second clamping members 41 and 42 are relatively rotated during clamping and unclamping of the track beam 300, the first and second connectors 413 and 423 may be moved relative to the mounting shaft 61 in the axial direction of the mounting shaft 61 to prevent the body drive assembly 60 from obstructing the relative rotation of the first and second clamping members 41 and 42 while achieving the coupling of the body drive assembly 60 with the first and second clamping members 41 and 42.
