[0028] A limit frame 7 is installed on the top of the support frame 2, and the load-bearing beam 5 is installed on the limit frame 7. Specifically, a through hole can be opened on the limit frame 7, and the load-bearing beam 5 is inserted into the through hole, and the distance between the hanging basket body 1 and the side of the bridge body is adjusted by adjusting the position of the load-bearing beam 5 on the limit frame 7. Further, in order to ensure the stability and safety of the hanging basket body 1 during use, the load-bearing beam 5 and the limit frame 7 in this embodiment are both matched with two, and are respectively arranged on both sides of the top of the support frame 2. One end of the two load-bearing beams 5 is connected to the counterweight frame 3, and the other end is connected to the connecting beam 8. The connecting beam 8 is connected to the adjustment frame 6 through connecting bolts and other connecting parts. In order to reduce the difficulty of adjustment, the limit frame 7 in this embodiment is a hollow structure and the inner wall is installed with two rows of limit rollers 9 arranged opposite to each other up and down, and the load-bearing beam 5 is inserted between the two rows of limit rollers 9. The load-bearing beam 5 is provided with a limiting groove matched with the limiting roller 9, so that the load-bearing beam 5 can stably slide on the inner wall of the limiting frame 2, thereby adjusting the distance between the hanging basket body 2 and the side of the bridge body.

[0029] In order to reduce the difficulty of installing the bridge deck track 4, in this embodiment, a mounting hole is opened on the bridge deck track 4, and a detachable connection between the bridge deck track 4 and the bridge deck is achieved by inserting locking bolts and other connecting parts into the mounting hole, making the disassembly and assembly of the bridge deck more convenient and facilitating subsequent repairs.

[0030] The bottom of the counterweight frame 3 is provided with brake wheels 11 near the four corners, which facilitates synchronous movement with the basket body 1 on the one hand, and prevents the movement of the basket body 1 due to the movement of the counterweight frame 3, thereby ensuring the stability of the basket body 1. The bottom of the support frame 2 is provided with moving pulleys 12 near the four corners, and the inner wall of the bridge deck track 4 is adapted to the moving pulleys 12, thereby realizing the movement of the support frame 2.

[0031] In order to realize the movement of the above-mentioned hanging basket body 1 in the up and down direction, in this embodiment, an adjustment mechanism for adjusting the up and down position of the above-mentioned hanging basket body 1 is also installed on the inner wall of the above-mentioned adjustment frame 6, and the above-mentioned adjustment mechanism includes a load screw 13, a screw nut 14, a transmission wheel 15, a transmission belt 16 and a drive motor 17. The above-mentioned load screws 13 are two and are both arranged close to the side of the above-mentioned adjustment frame 6. The two screw nuts 14 are respectively installed on the outer walls of the two load screws 13. The two load screws 13 are both installed with a transmission wheel 15. The two transmission wheels 15 are connected through the transmission belt 16. One of the above-mentioned load screws 13 is installed at the output end of the above-mentioned drive motor 17, and the above-mentioned hanging basket body 1 is connected to the screw nut 14.

The brake stepper motor has no power loss during operation and only consumes energy when rotating. It has high energy efficiency, which helps save energy and reduce the operating cost of the basket.

[0032] The above-mentioned hanging basket body 1 is provided with an auxiliary pulley 19, and the above-mentioned auxiliary pulley 19 is set in contact with the side of the bridge. The hanging basket body 1 can be lifted and lowered by fitting the side of the bridge body through the auxiliary pulley 19, thereby reducing the wear on the side of the bridge body and reducing the friction resistance of the hanging basket body 1 during the movement, so that the hanging basket can be quickly moved to the desired position. In order to balance and stabilize the movement of the hanging basket, the above-mentioned auxiliary pulleys 19 are multiple, and the multiple auxiliary pulleys 19 are symmetrically installed on the above-mentioned hanging basket body 1, so that the hanging basket body 1 is more stable when moving horizontally or vertically, and the shaking and swaying of the hanging basket body 1 during the movement are reduced. The arrangement of the auxiliary pulleys 19 makes the weight of the hanging basket body 1 evenly distributed on each pulley, reducing the load of a single pulley and improving the stability and safety of the entire hanging basket. At the same time, the symmetrical arrangement of the auxiliary pulleys 19 also helps to reduce friction, making the movement of the hanging basket smoother and easier, so as to improve the movement efficiency and stability of the hanging basket and ensure the safety of construction workers.

[0033] The hanging basket in this embodiment, in which the load-bearing beam 5 can slide in the limit frame 7, can adjust the distance between the hanging basket body 1 and the bridge deck. After the adjustment is completed, the limit frame 7 and the load-bearing beam 5 can be positioned by bolting. During the sliding process, the limit roller 9 can slide in the limit grooves on both sides of the load-bearing beam 5, so that the adjustment process is smoother. The counterweight block 10 can be placed on the top of the counterweight frame 3 for counterweighting to improve stability; start the brake stepping motor to rotate one side of the load screw 13, the transmission wheels 15 of the load screws 13 on both sides are connected by the transmission belt 16, and the load screws 13 on both sides rotate synchronously and can drive the hanging basket body 1 to fit the adjustment through the screw nut 14 The section frame 6 is raised and lowered, so that the workers in the basket body 1 can raise and lower the side plates of the bridge body, thereby adjusting the construction position vertically; when the brake wheel 11 is turned on, the counterweight frame 3 and the support frame 2 can move synchronously on the bridge deck, and the bridge deck track 4 can limit the support frame 2, so that the basket body 1 can move stably laterally on the side of the bridge body, thereby adjusting the construction area laterally; such a mobile bridge basket does not need to be equipped with a crane, and only the bridge deck track 4 needs to be installed on the bridge deck to fit and push the bridge body to move smoothly, thereby adjusting the construction area, facilitating disassembly and movement, and can be raised and lowered, with a larger construction area, thereby facilitating construction operations on the side of the bridge.
