Real-time monitoring close-fitting checker for railway turnout switch rail or point rail state

Abstract

The invention relates to a real-time monitoring close-fitting checker for a railway turnout switch rail or point rail state. The checker comprises a bottom shell, an indication rod, a machine cover, an acquisition extension set, a sensor, an information magnetic strip, a pressing plate, a copper sleeve and a cover barrel. The indication rod is arranged on the bottom shell, and the copper sleeve and a Y-shaped sealing ring are arranged at the joint of the bottom shell and the indication rod; the information magnetic strip is arranged in the indication rod, and the sensor is arranged on the bottom shell and keeps a distance with the information magnetic strip, so that the sensor senses the information magnetic strip, reads data and transmits the data to the acquisition extension set; and theacquisition extension set is fixed on the bottom shell through a pressing plate. Through the information magnetic strip, the sensor and the acquisition extension set, the dynamic gap and the static gap of the switch rail or the point rail state are monitored, pre-alarm and alarm are performed on the gap after operation, monitoring values are transmitted and stored in real time, and a relative chart is generated. The checker has the advantages of being simple in structure, convenient to install, capable of achieving real-time monitoring and early warning, capable of achieving whole-process monitoring and capable of improving the protection performance of the whole machine.

Description

technical field [0001] The invention belongs to a tightness checker for checking the closeness state of a point rail and a center rail of a railway turnout, in particular to a closeness checker for real-time monitoring of the state of a point rail or a center rail of a railway turnout. Background technique [0002] The tightness checker is used to check the tightness of the switch rail and the center rail, and it can also be used to cut off the turnout when the switch is squeezed. [0003] At present, the JM-A type adhesive checker is the largest adhesive checker in the market. The JM-A close-fit checker is suitable for straight-through turnouts towed by trains at speeds above 120km / h, and checks 5mm between two towing points. It can only check the tightness of one tongue rail, so two tongue rails of each set of turnouts need two tightness checkers, which are installed on both sides of the line. [0004] Another commonly used JM2 close-fit checker is suitable for high-spee...

AI Technical Summary

Problems solved by technology

[0006] 1) It is easy to be affected by the structure, resulting in improper contact conversion, jamming, and affecting the display;

[0007] 2) Only manual on-site inspections can be used to check the status of sticking and repelling, and there is no way to warn in advance;

[0008] 3) The indication rod is a square rod and the seal of the guide sleeve is poor, and it is easy to get water and foreign objects to cause the indication rod to jam;

[0009] 4) There are many parts processed in the machine and the assembly and adjustment process is complicated;

[0010] 5) There are many parts in the installation device, and the on-site installation is cumbersome
