Detachable road steel bridge handling and erecting vehicle with general height installation

Abstract

The invention provides a detachable highway steel bridge carrying and erecting vehicle of average height installation. The vehicle comprises a middle lifting roller assembly, a vehicle body and a lifting plate assembly; the middle lifting roller assembly is detachable and the position is adjustable, two forks crossing the vehicle body is horizontally installed in the middle of the vehicle body in the vertical direction; the lifting plate assembly mounted behind the vehicle body is detachable and the position is adjustable. Compared with the prior art, most of the components are detachable and it is not necessary to change any structures of the existing forklift; modular design is adopted, most of the components in assemblies is in common use and easy to maintain and manage; the structure of the erecting vehicle is adjustable, which is capable of completing ultralow posture work; a guider roller is replaced by a detachable retainer ring and therefore the work flexibility is increased. And the retainer ring can adjust position according to the need and is suitable for beams with various specifications and sizes; after the vehicle body is additionally provided with a front lifting roller assembly, the labor intensity is reduced and posture of devices including a truss and the like can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of engineering operation equipment, and in particular relates to a detachable highway steel bridge transporting and erecting vehicle installed at a general height. Background technique [0002] Prefabricated highway steel bridges, as one of the war preparation materials reserved by the Ministry of Communications on behalf of the country, have been widely used for decades, whether in wartime highway bridge repairs and rush construction, overcoming river obstacles, or in peacetime earthquake and flood rescue and disaster relief , traffic security are playing an irreplaceable role. [0003] During the erection process of the prefabricated highway steel bridge, it is necessary to rely on manpower to move the trusses, beams, etc. to the transport and erection vehicle, and then carry out docking. There are currently two types of auxiliary erection equipment for prefabricated highway steel bridges. One is propulsi...

AI Technical Summary

Problems solved by technology

There are currently two types of auxiliary erection equipment for prefabricated highway steel bridges. One is propulsion equipment, such as flat rolls, rockers, lower string joints, and inclined chords, and the other is installation tools, such as wrenches, crowbars, and mallets. etc., but none of these devices can realize the handling and erection of trusses and beams

[0004] Although the existing transport and erection equipment (vehicles) can carry and erect trusses and beams, most of the existing transport and erection equipment (vehicles) are integrally non-detachable, and their positions are fixed and invariable. The lifting of the hydraulic oil pipe of the auxiliary operation equipment is adjusted, and the equipment itself cannot be adjusted, so it is difficult to carry items of different specifications; considering the complex and changeable operation area, sometimes the height of the truss may be close to the height of the upper surface of the forklift, and it will not be possible to operate at this time, and it will not be possible to achieve super Low-level operation; due to the excessive friction between the surface of the shelf and the truss, the movement is laborious, which affects the efficiency of the truss docking
