Technical Field

The invention relates to the technical field of trestles, in particular to an electromechanical-hydraulic integrated self-propelled hydraulic trestle.

Background

The trestle is a bridge building for a locomotive vehicle to go to a ferry, consists of piers, abutments and steel beams, and is a temporary bridge facility built for transporting materials, equipment and personnel in civil engineering, which is divided into a wood trestle and a steel trestle according to the adopted materials; in the projects such as tunnels, the trestle is also adopted to assist in paving the concrete on the road surface.

The existing trestle has defects in the use process, and as most of the trestles are fixed in structure and large in length, the trestles are not convenient and fast in the transportation process and cannot be transported conveniently and fast; and current landing stage is at the inside in-process of marcing in tunnel, because the road surface unevenness, both sides wheel hub is the same, can lead to the landing stage to overlook the face and incline, leads to it to the tunnel both sides interval inequality to in the in-process of continuing to marcing, can increase deflection angle, thereby cause very big degree inconvenience.
