[0020] In this embodiment, the lower sides of the first bent horizontal beam 1 - 1 and the second bent oblique beam 1 - 2 are both equipped with walking rollers 5 for contacting the upper plane of the bridge 4 and the inner side of the bridge 4 .

[0021] Positioning devices 6 are respectively installed on the first bent horizontal beam 1 - 1 and the second bent oblique beam 1 - 2 .

[0022] like Figure 4 As shown, the positioning device 6 includes a screw rod 6-1 with an external thread, a turntable 6-2 and a positioning member 6-3. A through hole with an internal thread is opened at the corresponding positions of the first bending horizontal beam 1-1 and the second bending oblique beam 1-2. The screw rod 6-1 is inserted into the through hole. The outer end of the screw rod 6-1 is connected to the turntable 6-2, and the inner end of the screw rod 6-1 is connected to the positioning member 6-3. Rotating the turntable 6-2 drives the screw rod 6-1 to rotate, and the rotation of the screw rod 6-1 drives the positioning member 6-3 to move.

[0023] Wherein, the positioning member 6-3 is selected as a suction cup, and a high-power suction cup can be used.

[0024] When the device is in use, embodiment 1 is directly hung on the side of the bridge as a whole. Personnel enter the hanging basket through a ladder to perform corresponding construction operations. The device is displaced accordingly through the provided walking rollers and can also be positioned through the positioning device. The implementation of this device facilitates corresponding operations on the bridge, improves the comfort and safety of personnel while ensuring construction safety, and further improves the efficiency of bridge construction.

[0027] In this embodiment, the positioning device 6 includes a screw rod 6-1 with an external thread, a turntable 6-2 and a positioning member 6-3. A through hole with an internal thread is opened at the corresponding positions of the first bent horizontal beam 1-1 and the second bent oblique beam 1-2. The screw rod 6-1 is inserted into the through hole.
