Problems solved by technology

During the erection process of the prefabricated highway steel bridge, with the increase of assembled components, the ground will subside unevenly after the erection roller bears a large pressure, resulting in the unevenness of the original erected rolling surface, making it difficult to assemble and align the components of the prefabricated highway steel bridge. After the road steel bridge was launched, it tilted, and it was difficult to correct the deviation, which affected the rapid installation and erection of the prefabricated road steel bridge
When pushing the bridge, when the ground subsidence at the front-end erection roll is too large, there will be dangers of the assembled highway steel bridge slipping forward and overturning, especially in the plateau and cold areas of our country, where the air is thin, the physical energy of the operators is exhausted quickly, and the physical strength is difficult to support , When pushing and pulling the bridge to the bridge position, more operators are needed, it takes a long time, and even the bridge erection guarantee task cannot be completed

Abstract

The invention discloses a foldable assembled highway steel bridge erecting platform, which is composed of an oil cylinder outrigger assembly, a side bracket, a double-row erection roller assembly, a single-row erection roller assembly, an oil cylinder latch assembly, and an oil cylinder turning mechanism assembly. It is composed of Cheng and Zhong brackets, hydraulic winch and hydraulic control system. The erection platform is compact in structure, foldable, and easy to transport; when erecting a prefabricated highway steel bridge without a prefabricated abutment, the height of the erection platform can be adjusted through the outriggers of the oil cylinder to meet the requirements of ramp erection; the single-row erection roller assembly can Quickly adjust the positioning to meet the erection requirements of different types of prefabricated highway steel bridges; fully mechanized operations reduce the labor intensity of the prefabricated highway steel bridge erectors and improve the speed and safety of the prefabricated highway steel bridge erection.

Description

technical field [0001] The invention relates to a foldable assembled highway steel bridge erecting platform. Background technique [0002] The cantilever push method is a commonly used erection method for existing prefabricated highway steel bridges. It usually takes a long time to level the erection site when erecting with this method, stake out and mark the line to determine the erection roll position, and place multiple erection rolls on the ground to form the erection roll. flat. During the erection process of the prefabricated highway steel bridge, with the increase of assembled components, the ground will subside unevenly after the erection roller bears a large pressure, resulting in the unevenness of the original erected rolling surface, making it difficult to assemble and align the components of the prefabricated highway steel bridge. After the highway steel bridge was launched, it tilted, and it was difficult to correct the deviation, which affected the rapid insta...
