Assembling highway steel bridge transporting and erecting vehicle

Abstract

The invention discloses an assembling highway steel bridge transporting and erecting vehicle which comprises a goods shelf, a pedal, an oil cylinder base, an oil cylinder and a handle. A vertical plate is fixed on the goods shelf, a top plate is fixed on the vertical plate, and the vertical plate is connected with the oil cylinder base through a left A connection sheet and a right A connection sheet. The oil cylinder comprises a large plunger and a small plunger, wherein the large plunger is connected with the top plate, and the top end of the small plunger is contacted with the bottom end of the handle. A back wheel is arranged at the lower end of the oil cylinder base, and a universal wheel is arranged on each of two sides at the front end of the goods shelf. The universal wheels are connected with a front wheel cross plate, the front end of the front wheel cross plate is hinged to a front wheel front frame, the front wheel front frame is hinged to a front wheel support seat disposed at the bottom at the front end of the goods shelf, the back end of the front wheel cross plate is hinged to a front wheel back frame, and the front wheel back frame is hinged to the goods shelf. A pivot point of the pedal is hinged to the back end of the goods shelf, and the pedal is connected with the vertical plate or the top plate through an A spring. The assembling highway steel bridge transporting and erecting vehicle can solve 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 highway steel bridge handling equipment, and in particular relates to an assembled highway steel bridge handling and erecting vehicle. 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 high, and it costs a lot of mon...
