Abstract

A railway steel rail center detection vehicle comprises a walking trolley and a prism measuring device. The walking trolley comprises a frame and a hand push rod, a nylon wheel is arranged at the bottom of one end of the frame and arranged on the left steel rail, and a steel groove wheel is arranged at the bottom of the other end of the frame and clamped on the right steel rail; the prism measuring device comprises a prism, a prism bar and a knuckle bearing seat, a mounting hole is formed in the middle of the knuckle bearing seat, a knuckle bearing is arranged in the mounting hole, limiting holes are formed in the two side faces of the knuckle bearing seat, bolts are arranged in the limiting holes and abut against the knuckle bearing, and the knuckle bearing seat is connected with the frame. One end of the prism bar is connected with the prism, the center of the prism coincides with the center of the right steel rail, the other end of the prism bar is in threaded connection with one end of a prism bar connector, the other end of the prism bar connector is inserted into the knuckle bearing, and a universal support is connected between the prism bar and the frame. The railway steel rail 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 rail 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...
