Multi-cylinder outrigger combined low-level beam transport vehicle with beam support

Abstract

A multi-oil-cylinder-supporting-leg combination type low-position girder transporting vehicle with girder erection supports comprises a vehicle body, telescopic legs fixed at the tail of the vehicle body, a movable girder carrying trolley mounted on the vehicle body, oil cylinder supporting leg groups used for supporting the vehicle body and mounted on the lower portion of the vehicle body, carrying transport cushion boxes mounted on the vehicle body during inter-bridge transfer, traveling and steering wheel sets mounted below the vehicle body, front anchor bars mounted at the front end of the vehicle body, an electrical system, a hydraulic system, an air brake system, a power system and a cab, wherein the electrical system, the hydraulic system, the air brake system, the power system and the cab are mounted at the tail of the vehicle body. The multi-oil-cylinder-supporting-leg combination type low-position girder transporting vehicle with the girder erection supports has the advantages that the telescopic legs can serve as the girder erection supports, and the height of the tail of a bridge erection machine can be adjusted to adapt to ramp girder erection, so that a bridge erection technology and a corresponding support structure design of the bridge erection machine are simplified; by means of the multi-oil-cylinder-supporting-leg combination design, the supporting leg groups can adapt to dispersed girder erection load through force limiting control of oil cylinders, so that the vehicle body and supported girder pieces are balanced in stress.

Description

technical field [0001] The present invention relates to the technical field of railway construction machinery and equipment, in particular to a multi-cylinder outrigger combination with girder support for the transportation and erection of large prefabricated box girders on high-speed railway passenger dedicated lines, and is especially suitable for box girder transportation and erection in tunnels Type low beam transporter. Background technique [0002] With the continuous deepening of railway construction, there are a large number of bridge-tunnel connection problems, especially in mountainous areas. At the same time, the tunnel may span the karst cave section in the tunnel, and the box girder needs to be moved and transported in the tunnel. Erection. The function of the general tunnel beam transport vehicle is only to realize the movement of the box girder, and the beam transport vehicle only bears the weight of the girder. The support of the beam erection is usually ac...

AI Technical Summary

Problems solved by technology

The support of the beam erection is usually achieved through the conversion of the outriggers of the supporting bridge erecting machine, which makes the design of the support system of the bridge erecting machine more complicated, increases the beam erection process, and is very unfavorable for the working conditions of the equipment tunnel and the entrance and exit of the tunnel.
