The output end of the driving assembly is drivingly connected to the pulley 10 and is suitable for driving the pulley 10 to rotate.

[0055] The specific working principle of the operating platform for the construction of the bridge 12 provided in this embodiment is as follows: when it is necessary to construct the bottom of the bridge 12, two sets of mobile components are used to support the bridge deck of the bridge 12, and at the same time, the two sets of mobile components are respectively connected to the two ends of the operating platform 1 through the first support frame 2, the first bracket 3 and the second bracket 4. According to the construction, the whole is embedded in the bridge 12 in a U-shaped shape, which improves the overall stability and safety. Then, the operating platform 1 is connected to the bottom of the bridge 12, and the pulley 10 can be driven to rotate by multiple driving motors 11 to move along the bridge 12. The operating platform 1 is adjusted to an appropriate position. At the same time, before installation, the second The bracket 4 is fixedly connected to the connection position of the first bracket 3 by bolts 7, so as to adjust the working height between the operating platform 1 and the bottom of the bridge 12, so as to facilitate the construction personnel to carry out construction on the operating platform 1 and improve the practicality. The first bracket 3, the second bracket 4 and the frame 101 are all welded by square tubes, with simple structure, short installation period, strong applicability, convenient turnover and low cost. Under the premise of ensuring the efficient construction of welding and painting processes at the bottom of the bridge 12, when the bridge 12 is constructed above the road, the road space below the bridge 12 is not occupied to avoid affecting the traffic. When the bridge 12 is located above the river, the construction content of the bottom of the cross-river bridge can be completed efficiently without polluting the water source. The technical problems that the existing operating platform will affect the road traffic under the bridge 12 and cause pollution to the surrounding environment are solved.
