Abstract

The invention discloses an automatic lifting type assembling highway steel bridge transporting and erecting vehicle which comprises a base, wherein an electric control box and a handrail are arranged at the back end of the base, a lifting goods shelf is arranged on the upper surface of the base, and a motor used for starting the lifting goods shelf is arranged in the base and is connected with the electric control box through a lead wire. The automatic lifting type assembling highway steel bridge transporting and erecting vehicle leads equipment loading and unloading to be simple, convenient, efficient, safe, fast, accurate and stable, and accordingly remarkably improves operation efficiency and saves various resources; and achieves mechanization of truss transporting and splicing, solves problems of large labor intensity and long time wasted on member connection and transport due to pure manual operation, and buys time for emergent campaign of our military and rescue and relief.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment for highway steel bridges, and in particular relates to an automatic lift-type conveying and erecting vehicle for assembled highway steel bridges. 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. However, in the erection and withdrawal operations of prefabricated highway steel bridges, especially when using the cantilever push-out method to erect and withdraw them, there are many types of parts and components, and the weight of a single component is large. The labor intensity during erection and withdrawal operations is...
