Abstract

The invention relates to a vehicle frame lifting device for a track construction vehicle. The vehicle frame lifting device comprises a vehicle frame (1), wherein a lifting device (2) is arranged on each of the front side and rear side of the vehicle frame (1) and comprises an oil cylinder (3) with a piston rod which is vertically arranged downwards, the oil cylinder (3) is fixedly connected to the vehicle frame (1), and a support plate (10) is arranged on the piston rod of the oil cylinder (3) and is arranged below the vehicle frame (1). The vehicle frame lifting device has the advantages that the structure is simple; when a track needs to be changed during the track construction, the vehicle frame is put up by virtue of the oil cylinders to change the track; the operation is rapid and safe, and the reliability is high; and the vehicle frame lifting device is applicable to the track laying of flat ground and tunnels, the construction progress of the track construction vehicle is accelerated, and the pouring quality of an integrated track bed is guaranteed.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a lifting device for a frame of a track construction vehicle. Background technique [0002] With the development of society, trains, subways, etc. have become a mode of travel commonly used by people in modern society. These means of transportation need to run on tracks. At present, the laying of tracks is the laying of rails that will be assembled at the rail assembly base. On the ballast bed, the entire laying work consists of the assembly, transportation and laying of the rail row, as well as the transportation and laying of the ballast. [0003] At present, most of the subway tracks use ballastless track, that is, the integral ballast bed is poured by concrete. Since the maintenance period of the newly constructed ballast bed needs 48 hours, the traveling device of the track construction vehicle cannot pass on the integral ballast bed in the maintenance period. The...
