Scissor lifting and retractable time-division overpass

Abstract

A scissor lifting and retractable time-division overpass belongs to the field of road transportation facilities, and is composed of a main bridge body, a sub-bridge body and a scissor lifting platform. Both ends of the bridge have the same structure and are symmetrically distributed. The scissor lifting and retractable time-division overpass has the beneficial effects that the main bridge body canrise and fall and the sub-bridge body can be retracted, when the sub-bridge body is retracted to the inside of the main bridge body, the overall length can be reduced, the space can be saved, thus the entire overpass can be conveniently transported, in times of heavy traffic, at areas with dense crowds, the scissor lifting and retractable time-division overpass can be temporarily constructed to serve as a temporary overpass, so that pedestrians and vehicles can pass conveniently, the rise and fall of the main bridge body and the retracting of the sub-bridge body can be carried out at the sametime, the construction and transfer efficiency is high, convenience and efficiency are achieved, and traffic jams can be effectively solved.

Description

technical field [0001] The invention relates to a time-sharing overpass with scissor lifting and retractable, specifically an overpass adopting a special structure, equipped with a scissor lifting platform and a lead screw device, and belongs to the field of road traffic facilities. Background technique [0002] With the development of society and the increase of urban population, the number of private cars has also increased, which has brought a great burden to urban roads. Traffic congestion has become the norm, especially during holidays and commuting hours, which puts pressure on the traffic police It is very large, although there are already overpasses, but because most of the overpasses are made of reinforced concrete, and the construction is very high, the construction technology is difficult and the cost is expensive. Once the overpass is damaged, it is very difficult to repair the overpass. Many cities have not built overpasses , can not solve the road congestion we...

AI Technical Summary

Problems solved by technology

[0004] The scissor lift is a professional equipment for high-altitude operations with a wide range of uses. Its scissor-type mechanical structure makes the lift have high stability after lifting, and the wide operating platform and high carrying capacity enable it to be more Good support for the main bridge deck, although it is often used in mobile high-altitude operations such as high-altitude equipment installation and maintenance in various industries, it is relatively rare in the application of overpasses
