Embodiment 1

[0020] Such as Figure 1 to Figure 3 As shown, a safe working platform for girder bridge steel web coating is composed of a main truss system 1, a working platform system 2, a walking system 3 and a counterweight system 4; the main truss system 1 consists of a horizontal main truss 11 and a vertical The main trusses 12 are connected to form an L-shaped structure; the working platform system 2 is fixedly connected by the working platform 21 and the guardrail 22. Oppositely set; walking system 3 is composed of walking truss 31 and roller group 32. Walking system 3 is pulled by a car to drive the entire safety work platform to move. Walking truss 31 is connected with transverse main truss 11 to form a T-shaped structure; counterweight system 4 Including the main counterweight box 41 and the auxiliary counterweight box 42, the main counterweight box 41 is set on the end of the horizontal main truss 11 away from the vertical main truss 12, and is used to balance the self-weight of ...

Embodiment 2

[0029] When carrying out steel web coating and steel web decoration, the horizontal main truss 11 and the walking system 3 are installed and fixed, and erected on the end of the bridge deck close to the bridge edge, and the vertical main truss 12 and the working platform system 2 are installed and fixed. Use the crane to lift the vertical main truss 12 and the working platform system 2, use the bolts to connect and install the horizontal main truss 11 and the vertical main truss 12, and adjust the length of the vertical main truss 12 according to the site conditions. After the whole system is assembled, two strip steel plates with a thickness of 0.5cm, a width of 35cm and a length of 2m are laid under the four wheels 32 of the walking system 3, and they are laid while walking, alternately in turn, to play a role in asphalt pavement. protective effect. The fixed end of the safety rope is arranged at the water discharge hole, and the staff fastens the safety rope, boards the wor...

Embodiment 3

[0031] When the safe work platform is running, the work platform system 2 may be unbalanced, because the whole system is balanced according to the principle of leverage, so it may be that the counterweights of the main counterweight box 41 and the auxiliary counterweight box 42 are related to the staff and operating equipment. Unbalanced weight. Within the allowable range of the carrying capacity of the platform equipment, add and subtract water to the counterweight box in a timely manner according to the actual situation on site to ensure the balance and stability of the entire system.

Abstract

A safe working platform for girder bridge steel web coating is composed of a main truss system, a working platform system, a travelling system and a counterweight system. The main truss system is of an L-shaped structure composed of a transverse main truss and a vertical main truss which are connected. The working platform system is formed by a working platform body and guardrails which are fixedly connected, and the working platform body is fixedly mounted at the lower end of the vertical main truss. The travelling system is composed of a travelling truss and idler wheel sets which are matched, and the travelling truss and the transverse main truss are connected into a T-shaped structure. The counterweight system comprises a main counterweight box and an auxiliary counterweight box, the main counterweight box is arranged at the end, away from the vertical main truss, on the transverse main truss, and the auxiliary counterweight box is arranged at the end, close to the vertical main truss, on the working platform body. The safe working platform for girder bridge steel web coating has the beneficial effects of being simple in structure, convenient to mount and dismount, flexible inuse, reliable and stable in performance, high in controllability and adaptability, large in operating range, wide in span, high in construction efficiency, capable of lowering labor and material waste, safe and reliable.

Description

technical field [0001] The invention belongs to the field of girder bridge steel web coating, in particular to a safe working platform for girder bridge steel web coating. Background technique [0002] Bridge engineering is an important part of highway, railway, and municipal road engineering; and the bridge web is an indispensable part of the bridge superstructure. In a highway construction project, the quality and appearance of the bridge web structure affects the quality and appearance of the entire bridge structure. The web of the bridge is divided into ordinary concrete web and steel web. The maintenance, modification, maintenance and repair of ordinary concrete webs after formwork removal are inseparable from the working platform, while the secondary coating, inspection and later maintenance and repair of steel webs of steel web girder bridges are also inseparable from safety work platform. When the steel web bridge is painted on site after the construction of the s...
