As shown in fig. 1 to 11, an embodiment of the present application discloses an aerial work platform structure for installing a cable bridge 730 or a cable, comprising a bearing assembly 100, the bearing assembly 100 comprising a bridge support 200, a telescopic frame 300 and a cross arm 400, the bridge support 200 being used for installing the cable bridge 730. Alternatively, a cross arm 740 may be provided on the side of the bridge post 200, and the cable bridge 730 may be mounted on the cross arm 740.

Both the bridge pillar 200 and the telescopic frame 300 can be suspended on the top foundation 710, the bridge pillar 200 and the telescopic frame 300 are distributed at intervals in the transverse direction (the direction indicated by the y arrow line in fig. 1), the first end of the cross arm 400 is detachably connected with the bridge pillar 200, the second end of the cross arm 400 is connected with the telescopic frame 300, the cross arm 400 is located below the cable bridge 730, the cross arm 400 is used for laying a supporting plate 720 capable of carrying an operator, the telescopic frame 300 can drive the cross arm 400 to move in the vertical direction, that is, the telescopic frame 300 can drive the cross arm 400 to ascend or descend. Alternatively, the bridge support 200 may be connected to and suspended from the top foundation 710 by expansion screws, or the bridge support 200 may be connected to and suspended from the hooks of the top foundation 710 by the suspension rings 311 or hooks; the telescopic frame 300 may also be connected to the top base 710 by the two connection methods, which are not described herein.

It should be noted that, the top foundation 710 may be a concrete floor slab located at high altitude, a steel structure floor slab located at high altitude, or other installation foundation located at high altitude.

In the embodiment of the present application, the first end of the cross arm 400 is detachably connected to the bridge pillar 200, the second end of the cross arm 400 is connected to the telescopic frame 300, the cross arm 400 is used for laying the support plate 720, and an operator can stand on the support plate 720 to perform an operation, because the cross arm 400 and the telescopic frame 300 can be suspended on the top foundation 710, that is, the bridge pillar 330, the telescopic frame 300 and the cross arm 400 are not erected on the ground, the high-altitude operation platform structure of the present application does not occupy the ground and the installation space of the equipment above the ground, so that the equipment or the construction ground can be installed at the same time when the cable bridge 730 or the cable is laid, and the construction period can be shortened.

In addition, the embodiment of the present application uses the bridge pillar 200 for installing the cable bridge 730 to connect the first end of the cross arm 400, which does not require additional components on the top foundation 710 to connect the first end of the cross arm 400, thereby simplifying the structure of the aerial work platform structure; and after the first end of the cross arm 400 is separated from the bridge pillar 200, the telescopic frame 300 can drive the cross arm 400 to ascend or descend, so that the elevation of the cross arm 400 can be adjusted, and the height of the operator can be adjusted, so that the cable bridges 730 or cables with different heights can be conveniently installed.

Optionally, the first end of the cross arm 400 may be detachably connected to the bridge pillar 200 by a bolt, but when the structure is adopted and the height of the operator needs to be lifted, the bolt at the first end of the cross arm 400 needs to be detached to separate the first end of the cross arm 400 from the bridge pillar 200, and then the telescopic frame 300 can drive the cross arm 400 to move in the vertical direction, which obviously makes it cumbersome to lift the height of the operator.

In an alternative embodiment, referring to fig. 1 and 2, a plurality of clamping structures are disposed on a bridge pillar 200, the plurality of clamping structures are distributed at intervals in a vertical direction, the clamping structures include a first elastic member (not shown in the figure) and a clamping member 510, the clamping member 510 can move relative to the bridge pillar 200, a matching structure is disposed at a first end of a cross arm 400, and the first elastic member is connected with the clamping member 510 and can drive the clamping member 510 to move towards a direction close to the matching structure, so that the clamping member 510 is in clamping fit with the matching structure; the clamping member 510 can move away from the mating structure along with the ascending of the bridge pillar 200 to release the clamping engagement with the mating structure.

The specific working process is as follows, scalable frame 300 is at the in-process that drive cross arm 400 risees, and cross arm 400 can touch and extrude joint spare 510, and joint spare 510 can be to the direction activity of keeping away from cross arm 400, and first elastic component takes place elastic deformation, along with cross arm 400 continues to rise, cross arm 400 no longer extrudees joint spare 510 at a moment, at this moment first elastic component resumes elastic deformation, joint spare 510 can be towards the direction activity of being close to cross arm 400 under the drive of first elastic component, thereby make joint spare 510 and cooperation structure joint cooperation, cross arm 400 is connected with crane span structure pillar 200 this moment, in order to bear backup pad 720 and the load of exerting on backup pad 720. After the clamping piece 510 is clamped and matched with the matching structure, if the cross arm 400 is further driven to ascend, the cross arm 400 will extrude the clamping piece 510 again, and the clamping piece 510 moves towards the direction away from the cross arm 400 again, so that the clamping and matching with the matching structure is released, and the purpose of improving the operators is achieved. Therefore, after the embodiment of the application is adopted, the first end of the cross arm 400 can be lifted by using the telescopic frame 300 without detaching the first end of the cross arm 400 from the bridge support 200, so that operators can be lifted, and the operation flow of the high-altitude operation platform structure can be simplified.

Optionally, the bridge support 200 is provided with an accommodating groove, the clamping member 510 is slidably disposed in the accommodating groove, two ends of the first elastic member are respectively connected with the bridge support 200 and the clamping member 510, one end of the clamping member 510 can extend out of the accommodating groove under the driving of the first elastic member to be in clamping fit with the matching structure, and in the process of lifting the bridge support 200, the portion of the clamping member 510 extending out of the accommodating groove can be extruded into the accommodating groove by the bridge support 200. The engaging member 510 may be a plate member, and the mating structure may be a slot 421.

In an alternative embodiment, referring to fig. 3 and 4, the number of the clamping members 510 is two, the two clamping members 510 are symmetrically arranged, the clamping members 510 include a stopping portion 511, a connecting portion 512 and a clamping portion 513 which are sequentially connected, the stopping portion 511 and the clamping portion 513 are respectively bent by the connecting portion 512, the stopping portion 511 and the clamping portion 513 are located on the same side of the connecting portion 512, the clamping portion 513 is located above the stopping portion 511, the bent portions of the stopping portion 511 and the connecting portion 512 are rotatably arranged on the bridge pillar 200, and the first elastic member can drive the two clamping members 510 to rotate in opposite directions. Alternatively, the number of the first elastic members may be two, each of the first elastic members is correspondingly connected to one of the clamping members 510, and one end of the first elastic member away from the clamping member 510 is connected to the bridge pillar 200, where the first elastic member may be a spring, a shrapnel, a torsion spring, or the like; or the number of the first elastic members may be only one, and at this time, two ends of the first elastic members are respectively connected to the two clamping members 510, and at this time, the first elastic members may be springs, elastic sheets, and the like. In addition, the grooves 250 may be formed on the bridge pillar 200, and the two clamping members 510 may be located in the grooves 250, so that the clamping members 510 occupy less space outside the bridge pillar 200 than if the clamping members 510 were formed on the outer surface of the bridge pillar 200.

The cross arm 400 is provided with a fitting piece 420 protruding towards one side of the bridge pillar 200, the fitting piece 420 is provided with a clamping groove 421, the fitting structure comprises the clamping groove 421, the fitting piece 420 can be supported by the two stopping portions 511, that is, the position of the fitting piece 420 can correspond to the position of the two stopping portions 511, the transverse distance between the two stopping portions 511 is smaller than the transverse length of the fitting piece 420, and under the condition that the fitting piece 420 is supported by the two stopping portions 511, the two clamping portions 513 are in clamping fit with the clamping groove 421. Alternatively, the number of the clamping grooves 421 may be only one, and the clamping grooves 421 may be annular grooves, and the clamping members 510 on both sides may be in clamping fit with the clamping grooves 421; or the number of the clamping grooves 421 can be two, at this time, the clamping grooves 421 are disposed at two sides of the matching piece 420, and the clamping pieces 510 at two sides can be respectively clamped and matched with the clamping grooves 421 at two sides.

Referring to fig. 10 and 11, the specific working process is as follows, because the lateral distance between the two stopping portions 511 is smaller than the lateral dimension of the mating member 420, when the mating member 420 is located under the two clamping members 510 and just contacts the two stopping portions 511, the mating member 420 touches and presses the two stopping portions 511, and the two stopping portions 511 rotate away from the mating member 420 back to the opposite direction, at this time, the first elastic member elastically deforms, the cross arm 400 and the mating member 420 are continuously lifted, the mating member 420 does not press the two stopping portions 511, the first elastic member returns to elastic deformation, the two clamping members 510 rotate in opposite directions under the action of the first elastic member until the clamping portions 513 contact the mating member 420, and when the mating member 420 is supported by the stopping portions 511, the clamping portions 513 are in clamping engagement with the clamping grooves, and because the mating member 420 applies downward pressure to the stopping portions 511, the two clamping members 510 have opposite directions, so that the clamping portions 513 further clamp the mating member 420, and the bridge frame 400 can be prevented from being separated from the bridge frame 400, and the bridge frame 400 is not required to be separated from the bridge frame 330.

It should be noted that, because the cable bridge 730 and the cable are laid from bottom to top, after the cable bridge 730 and the cable at the lower position are laid, the operator does not need to drop to the lower position, so that the aerial working platform structure is only suitable for the scene of lifting the operator upwards. In view of this, in the present embodiment, after the locking portion 513 is engaged with the locking groove 421, the cross arm 400 cannot move downward any more due to the structure of the locking member 510, so that the cross arm 400 can be prevented from being separated from the bridge upright 330.

In an alternative embodiment, referring to fig. 6, both sides of the mating member 420 are provided with first guiding surfaces 422, the first guiding surfaces 422 are located below the clamping grooves 421 and extend to the bottom surface of the mating member 420, the first guiding surfaces 422 gradually extend from top to bottom toward the inside of the mating member 420, that is, the distance between the two guiding surfaces gradually decreases from top to bottom, and the first guiding surfaces 422 can guide the stopping portion 511 from the side surface of the mating member 420 toward the bottom surface of the mating member 420. Alternatively, the first guide surface 422 herein may be a slope, a cambered surface, or the like.

If the first guide surfaces 422 are not disposed on the two sides of the mating member 420, as shown in fig. 10, when the first elastic member drives the two locking members 510 to rotate in opposite directions and the locking portion 513 contacts the mating member 420, the mating member 420 will be higher than the stopping portion 511, and if the mating member 420 is desired to support and press the locking portion 513, the telescopic frame 300 needs to drive the cross arm 400 to move downward, which obviously increases the operation complexity of the platform structure of the high-altitude work industry. Therefore, in the embodiment of the present application, the first guiding surfaces 422 are disposed at two sides of the matching piece 420, as shown in fig. 11, in the process of moving up the matching piece 420, the stopping portion 511 will contact with the first guiding surfaces 422 on the matching piece 420, and since the first guiding surfaces 422 have a certain inclination, the first guiding surfaces 422 cannot stop the stopping portion 511, the stopping portions 511 at two sides will rotate in opposite directions under the action of the first elastic member and move to a position closer to the bottom surface of the matching piece 420 along with the first guiding surfaces 422, at this time, the matching piece 420 can be separated from the stopping portions 511 at two sides only by moving up a small distance, and thus the matching piece 420 can be supported on the stopping portions 511 by moving down a small distance; even the two side stopping portions 511 move to the bottom surface of the mating member 420 along the first guiding surface 422, at this time, the mating member 420 is just supported by the stopping portions 511, and the clamping portions 513 just engage with the clamping grooves 421. Therefore, in the present embodiment, after the first guiding surface 422 is disposed on the matching member 420, the downward moving distance of the cross arm 400 can be reduced, and even the matching member 420 can be supported on the supporting portion 511 without moving the cross arm 400 downward, so that the control flow of the aerial work platform structure can be simplified.

Further, the second guiding surface 5112 is formed on the lower side of the first edge 5111 of the abutment 511, and the distance between the second guiding surface 5112 and the ground plane gradually increases in the direction in which the end of the abutment 511 connected to the connecting portion 512 extends toward the other end of the abutment 511, the second guiding surface 5112 may be an arc surface, an inclined surface, or the like, the second guiding surface 5112 may be slidably engaged with the first guiding surface 422, and the provision of the second guiding surface 5112 may reduce the distance between the lower side of the abutment 511 and the rotation axis of the locking member 510, so that the abutment 511 is more easily guided to the bottom surface of the engaging member 420.

In an alternative embodiment, referring to fig. 4, the edge of the stopping portion 511 facing away from the connecting portion 512 is a first edge 5111, the edge of the holding portion 513 facing away from the connecting portion 512 is a second edge 5131, and the first edge 5111 is laterally closer to the rotation axis of the clamping member 510 than the second edge 5131, that is, the lateral distance between the first edge 5111 and the rotation axis of the clamping member 510 is smaller than the lateral distance between the second edge 5131 and the rotation axis of the clamping member 510. In this embodiment, since the engaging member 420 first contacts the first edge 5111 of the abutting portion 511 during the upward movement, so as to drive the entire engaging member 510 to rotate, if the distance between the first edge 5111 and the rotation axis of the engaging member 510 is too large, i.e. the extending length of the abutting portion 511 is too large, the abutting portion 511 rotates by a larger angle when contacting the outer peripheral surface of the engaging member 420, which may cause the connecting portion 512 and the retaining portion 513 to also rotate by a larger angle, which may cause the engaging member 510 to interfere with the adjacent component, while the first edge 5111 of the present embodiment is closer to the rotation axis of the engaging member 510 than the second edge 5131 in the transverse direction, so that the transverse distance between the first edge 5111 and the rotation axis is reduced, and the extending length of the abutting portion 511 is reduced, so as to reduce the required rotation angle when the abutting portion 511 contacts the outer peripheral surface of the engaging member 420, thereby preventing the engaging member 510 from interfering with the adjacent component.

In an alternative embodiment, referring to fig. 3 and 5-7, the cross arm 400 includes a mating member 420 and a body portion 410 extending in a lateral direction, the mating member 420 being slidable laterally relative to the body portion 410 between a first position and a second position, and a second resilient member 430 being coupled between the mating member 420 and the body portion 410. Optionally, a sliding groove 411 extending in a transverse direction may be disposed on the main body 410, the mating member 420 is in limit fit with the sliding groove 411 in a circumferential direction, a sidewall of the sliding groove 411 is recessed inward to form a deepened portion 4111, an anti-pulling protrusion 423 is convexly disposed on an outer peripheral surface of the mating member 420, the anti-pulling protrusion 423 is slidingly engaged with the sliding groove 411, and the mating member 420 is prevented from being separated from the sliding groove 411 by the anti-pulling protrusion 423; or a part of the matching piece 420 is sleeved outside the main body part 410, and the matching piece 420 is in limit fit with the main body part 410 in the circumferential direction.

The bridge support 200 is provided with a plurality of limiting tables 210, each limiting table 210 is located below each clamping structure in a one-to-one correspondence manner, a transverse channel 220 for the matching piece 420 to enter is arranged between each limiting table 210 and each adjacent clamping structure, and an extrusion surface 230 is arranged on the lower side of each limiting table 210. Specifically, in the transverse direction, the distance between the pressing surface 230 and the ground plane gradually changes, which may be an inclined surface, an arc surface, or the like, and the fitting 420 may be pressed to one side of the stopper 210 in the transverse direction, i.e., the left side or the right side of the stopper 210, by the pressing surface 230, and then a vertical channel 260 may be provided at the left side or the right side of the stopper 210 for the fitting 420 to move in the vertical direction.

It should be noted that, the clamping structure adjacent to the limiting table 210 may be: the clamping structure located above the limiting platform 210 may be a clamping structure located below the limiting platform 210, that is, when the clamping structures are located above and below the limiting platform 210, the transverse channels 220 are formed between the limiting platform 210 and the lower clamping structure and between the limiting platform 210 and the upper clamping structure.

The pressing surface 230 can drive the matching piece 420 to slide from the first position to the second position, so that the matching piece 420 can avoid the limit table 210; the second elastic member 430 can drive the engaging member 420 to slide from the second position to the first position, so that the position of the engaging member 420 corresponds to the position of the locking structure, that is, two sides of the engaging member 420 are respectively opposite to the two locking members 510 in the vertical direction, and when the engaging member 420 is lifted, the locking groove 421 on the engaging member 420 can be locked and engaged with the locking portions 513 of the locking members 510 on two sides.

The specific working process is that, under the condition that the matching piece 420 is located at the first position, two sides of the matching piece 420 are respectively opposite to the two clamping pieces 510 in the vertical direction, during the upward movement of the cross arm 400, the matching piece 420 can be clamped and matched with the two clamping pieces 510, when the cross arm 400 continues to move upwards, the matching piece 420 can be released from clamping and matched with the two clamping pieces 510 and then is contacted with the limiting table 210 located above the limiting table, and because the limiting table 210 is provided with the extrusion surface 230, the matching piece 420 can slide relative to the main body part 410, under the extrusion of the extrusion surface 230, the matching piece 420 can slide transversely and drive the second elastic piece 430 to deform elastically, and when the matching piece 420 slides to the edge of the extrusion surface 230, the matching piece 420 can be staggered with the limiting table 210 in the vertical direction, thereby bypassing the limiting table 210 to be located at one side of the limiting table 210 along the transverse direction, and at the moment, the matching piece 420 is located at the second position; further lifting of the cross arm 400 may cause the engaging member 420 to be laterally displaced from the stop block 210, i.e., the engaging member 420 is located higher than the stop block 210, and the second elastic member 430 may recover the elastic deformation, so as to drive the engaging member 420 to slide from the second position to the first position.

In this embodiment, the limiting tables 210 are disposed below each clamping structure, so that even if two clamping members 510 are separated from the matching member 420, the limiting tables 210 can limit the matching member 420, so that the stability of the structure of the aerial work platform can be ensured; in addition, after the structure of the present embodiment is adopted, besides the two clamping members 510 can bear the matching members 420 of the cross arm 400, the limiting platform 210 can also bear the matching members 420 of the cross arm 400, that is, the limiting platform 210 can also be connected with the telescopic frame 300 together with the cross arm 400, so as to achieve the purpose of multiple purposes. It should be noted that, because the extrusion surface 230 is disposed on the limiting platform 210, the height of the limiting platform 210 is larger, that is, the height of the limiting platform 210 is larger than the height of the clamping member 510, if all the limiting platforms 210 are used to connect the cross arm 400 with the telescopic frame 300 together, under the condition of the same number, the limiting platforms 210 occupy more space in the vertical direction than the clamping member 510, so as to occupy space below the aerial work platform structure, therefore, the embodiment adopts the combination of the limiting platform 210 and the clamping member 510, which not only can reduce space below the aerial work platform structure, but also can ensure stability of the aerial work platform structure.
