[0005] With the above structure design, the assembly type platform is closed around the pier body, and a protective fence is provided at the edge, so that the working space is large, the stability is good, the safety measures are in place, the height of the pier is not limited, the construction environment is improved, and the construction difficulty and safety risk of high-altitude work are reduced.

[0006] Preferably, the pulley assembly includes two installation boxes fixedly connected symmetrically on one side of the footboard, a sliding rod is fixedly connected vertically in the installation box, a sliding support is symmetrically and slidably connected on the sliding rod, the sliding support extends out of the installation box and is rotatably connected with a push rod, both the push rods are rotatably connected to a support, a roller is rotatably connected between the two supports, a tension spring is sleeved on the sliding rod, and both ends of the tension spring are fixedly connected with the sliding support.

[0007] With the above scheme design, since the bridge pier facade has an arc, the tension spring can control the roller to always contact the bridge pier sidewall, thereby avoiding large shaking of the platform body, and improving the stability and smoothness of platform lifting.

[0008] Preferably, two pulley assemblies are symmetrically installed on the inner side of the pedal, and the roller abuts against the sidewall of the bridge pier.

[0009] With the above scheme design, the setting of the roller can prevent the pedal from colliding with the bridge pier, and also protects the fence to a certain extent.

[0010] Preferably, a counterweight box is arranged at the middle position of the upper end of the support frame.

[0011] With the above structure design, the counterweight box arranged on the support frame ensures the stability of the support frame, and prevents the support frame from overturning due to unbalanced stress when the two ends of the support frame are cantilevered.

[0012] Preferably, fences are arranged on the inner and outer sides of the pedal.

[0013] With the above structure design, the protective fence is arranged on the edge, the working space is large, the stability is good, the safety measures are in place, and the safety of the construction personnel is ensured.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] 1. The assembled platform is designed to be closed around the pier body, the protective fence is arranged on the edge, the working space is large, the stability is good, the safety measures are in place, the construction environment is improved, the construction difficulty and safety risk of high-altitude work are reduced, and the pier height is not limited.

[0016] 2. Since the bridge pier facade has an arc, the tension spring can control the roller to always contact the bridge pier sidewall, thereby avoiding large shaking of the platform body, and improving the stability and smoothness of platform lifting, and the construction personnel are more stable when installing the basket, and the installation quality and efficiency of the basket are effectively improved.
