Specific implementation

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0022] As Figures 1-5 shown, an assembled hanging basket for a steel bridge, comprising a bridge body 1, which is provided with a crash barrier 11, further comprising a mounting frame 21, which is provided with a traveling wheel 25, the mounting frame 21 is further provided with a hanging basket 24 through a cross beam frame 22 and a vertical beam frame 23, the movable seat 3 is arranged on the cross beam frame 22 to slide vertically, the supporting wheel 4 is arranged on the movable seat 3 to rotate horizontally, and the movable seat 3 is driven to slide vertically so that the supporting wheel 4 rolls against the top surface of the crash barrier 11.

[0023] Specifically, the supporting wheel 4 is arranged to rotate in the rotating hole 33 of the movable seat 3, as Figure 1As shown, the mounting frame 21 is mounted on the bridge body 1 via traveling wheels 25, while the hanging basket 24 is connected to the mounting frame 21 via a crossbeam frame 22 and a vertical beam frame 23. The hanging basket 24 is located on the outer side of the bridge body 1. When sliding parts 31 are symmetrically arranged on the movable seat 3, and a vertical groove 221 is provided on the crossbeam frame 22, the sliding parts 31 are slidably disposed in the vertical groove 221 so that the movable seat 3 can be vertically slidably arranged. At this time, the movable seat 3 is first located on the crossbeam frame 22, which strengthens the vertical deformation resistance of the crossbeam frame 22 and improves the support of the crossbeam frame 22 for the hanging basket. The support stability of the beam 24 is improved, and a second elastic element 92 is provided inside the beam 22. The second elastic element 92 pushes the movable seat 3 to slide vertically close to the anti-collision wall 11 so that the supporting wheel 4 abuts against the top surface of the anti-collision wall 11. This achieves the following: when the mounting frame 21 moves the hanging basket 24 by driving the traveling wheel 25, the supporting wheel 4 abuts against the top surface of the anti-collision wall 11 and rolls, thereby improving the movement stability of the beam 22 and avoiding the problem of large vertical shaking of the beam 22 during the movement, which would cause the hanging basket 24 to shake, thus reducing safety hazards.

[0024] In the above technical solution, the movable seat 3 slides vertically close to the anti-collision wall 11 so that the supporting wheel 4 abuts against the top surface of the anti-collision wall 11. This achieves the following: when the mounting frame 21 moves the hanging basket 24 by driving the walking wheel 25, the supporting wheel 4 rolls against the top surface of the anti-collision wall 11 to improve the movement stability of the crossbeam frame 22. This avoids the problem of the hanging basket 24 shaking due to large vertical shaking of the crossbeam frame 22 during movement, thus reducing safety hazards.

[0025] As a further embodiment provided by this utility model, a telescopic seat 5 is symmetrically slidably arranged on the movable seat 3, and a side guide wheel 6 is horizontally rotatably arranged on the telescopic seat 5. The telescopic seat 5 is driven to slide and move closer to each other so that the side guide wheel 6 rolls against the side of the anti-collision wall 11, and the rotation axis of the side guide wheel 6 is perpendicular to the rotation axis of the supporting wheel 4.

[0026] Specifically, such as Figure 2 As shown, the movable seat 3 is provided with a first elastic element 91, which pushes the telescopic seat 5 to slide closer to each other so that the side guide wheel 6 on the telescopic seat 5 abuts against the two sides of the anti-collision wall 11. When the mounting frame 21 drives the hanging basket 24 to move through the traveling wheel 25, the side guide wheel 6 abuts against the two sides of the anti-collision wall 11 and rolls forward, while the support wheel 4 abuts against the top surface of the anti-collision wall 11 and rolls forward. Thus, the support wheel 4 and the side guide wheel 6 are used to further improve the stability of the hanging basket 24 when the crossbeam frame 22 drives it to move.

[0027] Further, a horizontal sliding slot 32 is formed on the movable seat 3, a horizontal sliding block 51 is symmetrically arranged on the telescopic seat 5 and is slidingly arranged in the horizontal sliding slot 32, and a first elastic member 91 is arranged in the movable seat 3 and is used to drive the telescopic seat 5 to slide and approach, wherein the first elastic member 91 and the second elastic member 92 can be springs.

[0028] As further provided in the embodiments of the utility model, a guide sleeve 7 is arranged, and a fixed block 81 is fixedly connected to the guide sleeve 7 and is axially slidingly arranged on the supporting wheel 4 so that the guide sleeve 7 is coaxially arranged on the supporting wheel 4, and the fixed block 81 drives the guide sleeve 7 to axially slide so that a guide portion 71 arranged on a first end of the guide sleeve 7 abuts against a side surface of the crash barrier 11.

[0029] Specifically, as shown in Figure 3 the fixed block 81 is axially slidingly arranged on the supporting wheel 4, the left end of the guide sleeve 7 is the first end, a rounded corner is arranged at the first end of the guide sleeve 7 to form the guide portion 71, the fixed block 81 drives the guide sleeve 7 to axially slide along the supporting wheel 4 so that the guide portion 71 abuts against the side surface of the crash barrier 11, when the mounting frame 21 drives the beam frame 22 and the hanging basket 24 to move, the supporting wheel 4 rolls on the top of the crash barrier 11, and the supporting wheel 4 drives the guide sleeve 7 to synchronously axially rotate, thereby making the guide portion 71 of the guide sleeve 7 continuously move in the circumferential direction to approach both sides of the top of the crash barrier 11, at this time, the guide portion 71 can contact and limit the horizontal position between the crash barrier 11 and the supporting wheel 4, thereby reducing the horizontal error when the mounting frame 21, the beam frame 22 and the hanging basket 24 move, reducing the horizontal shaking of the hanging basket 24 during the movement, and improving the movement stability and safety of the hanging basket 24.

[0030] As further provided in the embodiments of the utility model, a plurality of protruding strips 72 are circumferentially arranged on the guide sleeve 7, and the supporting wheel 4 drives the guide sleeve 7 to rotate so that the protruding strips 72 are sequentially rotated in the circumferential direction into the space between the crash barrier 11 and the lateral guide wheel 6.

[0031] Specifically, as shown in Figure 3As shown, the guide sleeve 7 is circumferentially arranged with a plurality of protruding strips 72, when the mounting frame 21 drives the hanging basket 24 to move, the supporting wheel 4 and the lateral guide wheel 6 are in contact with the crash wall 11 to roll, and the supporting wheel 4 drives the guide sleeve 7 to rotate to make the protruding strips 72 rotate circumferentially to enter between the crash wall 11 and the lateral guide wheel 6 and be extruded by the lateral guide wheel 6, and then leave, so that the lateral guide wheel 6 forms a pressure mark on the side of the crash wall 11 through the protruding strips 72 periodically, and the moving distance of the mounting frame 21 and the hanging basket 24 is quickly judged by using the pressure mark, which is convenient for actual use, and since the protruding strips 72 are extruded by the lateral guide wheel 6, the lateral guide wheel 6 and the supporting wheel 4 are difficult to resonate even if they rotate synchronously, thereby avoiding the problem that the vibration amplitude of the cross beam frame 22 is increased due to the resonance of the lateral guide wheel 6 and the supporting wheel 4 caused by rolling. The moving stability of the hanging basket 24 is improved.

[0032] As further provided in the embodiments of the utility model, a hollow cavity 73 for storing water is arranged in the guide sleeve 7, and a plurality of extrusion holes 74 are arranged on the protruding strips 72 and are in communication with the hollow cavity 73.

[0033] Specifically, as shown in the drawings, Figure 3 The hollow cavity 73 can store water, and when the supporting wheel 4 drives the guide sleeve 7 to rotate to make the protruding strips 72 rotate circumferentially to enter between the crash wall 11 and the lateral guide wheel 6 and be extruded by the lateral guide wheel 6, the protruding strips 72 are extruded to make the water in the hollow cavity 73 extruded from the extrusion holes 74 to the crash wall 11, so that a clear travel mark is formed by using the water stain, and the travel distance of the mounting frame 21 and the hanging basket 24 is quickly judged, and the water extruded to the side of the crash wall 11 reduces the dust flying caused by the contact of the lateral guide wheel 6 with the crash wall 11, which is convenient for actual use.

[0034] As further provided in the embodiments of the utility model, a locking bolt 82 is further included, a guide sliding groove 41 is symmetrically arranged on the supporting wheel 4, a fixed block 81 is slidingly arranged in the guide sliding groove 41, and the locking bolt 82 is threadedly installed on the fixed block 81 and in contact with the guide sliding groove 41 to lock the fixed block 81.

[0035] Specifically, as shown in the drawings, Figure 3 A threaded hole 811 is arranged on the fixed block 81, the locking bolt 82 is threadedly installed in the threaded hole 811, and the end of the locking bolt 82 is in contact with the guide sliding groove 41 to lock the fixed block 81, so that the guide sleeve 7 is stably locked, and the position of the guide sleeve 7 is adjusted and locked.

[0036] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
