Abstract

A railway line center detection vehicle comprises a walking trolley, a track gauge measuring ruler, a superelevation detector and a prism measuring device, the track gauge measuring ruler comprises a bottom plate and two racks, an intermediate gear is arranged in the dead center of the bottom plate, one rack is arranged on one side of the intermediate gear, scales are arranged on the rack, the other rack is arranged on the other side of the intermediate gear. The rack is provided with a pointer and meshed with the intermediate gear, one end of the rack is sleeved with a spring, the other end of the rack is connected with an electric insulation bearing, the electric insulation bearing makes contact with the inner side face of the steel rail, the bottom plate and the rack are both sleeved with supporting frames, the supporting frames are connected with the walking trolley, and the prism measuring device comprises a prism, a prism rod and a pressing block. One end of the prism rod is connected with the prism, the other end of the prism rod is connected with the pressing block, and the pressing block is fixed to the portion, located over the middle gear, of the bottom plate. The railway line center detection vehicle has the advantages of high measurement precision, high working efficiency and low cost.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a railway line center detection vehicle, which is mainly suitable for improving measurement accuracy, improving work efficiency and reducing costs. Background technique [0002] Because the traditional ballast track measurement operation is to place a prism rod in the center of the rail for measurement, the placement position is estimated by the staff, and the error is relatively large. The prism group is also carried by the staff, so it is laborious; at the same time, the prism bracket is in the ballast. It is not easy to get a foot on it, so the placement speed is slow, and the staff often bend over, and the labor intensity is high and it is easy to get fatigued, so the overall work efficiency is low. At the same time, track fine-tuning requires the use of fine-tuning trolleys, which are expensive and have high rental fees. In addition, the rapid development of railways...
