Suspension type air railway measurement device

Abstract

The invention belongs to the technical field of railway measurement, particularly relates to a suspension type air railway measurement device, and aims to meet the daily detection and maintenance of the suspension type railway. The technical scheme of the device comprises a main body, a supporting structure, a positioning structure, a center line upright tube and a laser target, wherein the supporting structure can be movably installed along the length direction of a rail plate; the supporting structure and the positioning structure are fixed on the main body; the positioning structure is in contact with the side edges of rail plates which are symmetrically arranged in a left and right direction so as to position the main body between two rail plates; the center line upright tube is connected to the main body, is vertically arranged and points to the geometric center of the main body; the laser target is hinged to the center line upright tube; and the movement of the main body is driven by a power device or is manually controlled by an operation person. The device disclosed by the invention has the advantages of simple structure and low cost, can accurately measure railway coordinate information and meets the detection and the maintenance of the suspension type railway.

Description

technical field [0001] The invention belongs to the technical field of track measurement, and in particular relates to a suspended track measuring device for empty railways. Background technique [0002] The regular inspection of track beams is an important part of the track beam maintenance management system, which plays an important role in ensuring the safety of empty trains. In recent years, with the rapid development of the national rail transit industry, many new rail transit systems have emerged, such as suspended track The transportation system is also called aerial track, or empty track for short. Its characteristic is that the vehicle is suspended under the box-shaped track beam, and the track beam is supported in the air by steel columns or reinforced concrete columns. And travel along the track set inside the beam body. [0003] The track beam is not only the load-bearing structure of the train, but also the track on which the train runs. It has multiple functio...

Problems solved by technology

In addition, the center line between the left and right track slabs is the center line of the track. After the track beam is installed, the center line of the track changes with the influence of various factors such as the settlement of the underground foundation, the deformation of the frame parts, and the dynamic load of the train. When the change value exceeds the specification Requirements, will affect the stability of the train running, and even cause traffic safety hazards
