Monitoring device for deformation of ballastless track plate

Abstract

The invention discloses a monitoring device for deformation of a ballastless track plate. The monitoring device comprises an energy conveying unit and a monitoring mechanism which is in communicationconnection with the energy conveying unit, wherein the monitoring mechanism comprises a base, a mounting stop block arranged on the base and provided with a horizontal top surface and an inclined surface, and a double-pin joint meter which is in contact with the mounting stop block; the double-pin joint meter comprises a fixing part internally provided with an integrated element, and a first jointmeter and a second joint meter which are arranged on the two sides of the fixing part; the bottom end of the first joint meter is in contact with the inclined surface of the mounting stop block, andthe bottom end of the second joint meter is in contact with the horizontal top surface of the mounting stop block; the fixing part is further provided with a wiring part which is in communication connection with the integrated element; through the combined connecting effect between the double-pin joint meter and the special mounting stop block, synchronous monitoring of vertical arch deformation and horizontal expansion deformation of the ballastless track plate end is effectively realized, and the monitoring device is high in monitoring precision, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of engineering safety monitoring equipment, in particular to a monitoring device for deformation of a ballastless track slab. Background technique [0002] With the vigorous development of high-speed railways in my country, more and more high-speed railway structural deformation monitoring requirements have been put forward to ensure the safety of high-speed railway construction and operation, both in the construction period and in the operation period. Among them, the ballastless track slabs expand longitudinally when heated, thereby squeezing the joints between the track slabs. As expansion continues and cannot be absorbed by the seam, the end of the track slab arches upward relative to the base foundation causing cracks between the track slab and the base foundation. The generation of cracks will affect the structural safety of ballastless track. The vibration and impact of high-speed operating trains w...

AI Technical Summary

Problems solved by technology

The vibration and impact of high-speed operating trains will further increase the impact of cracks on the track structure, thereby endangering the safety of operating trains

The accuracy of monitoring is very high, the operating railway is closed, the existing monitoring mechanism has low monitoring accuracy, poor stability and reliability, and cumbersome operation
