A device for detecting and melting ice and snow on the tip rail and basic rail of a railway turnout

Abstract

A device for preventing a railway turnout from freezing is characterized by comprising control boxes, heat conduction plates, temperature sensors, rain and snow sensors, the temperature sensors and the rain and snow sensors which are the same are installed close to sleepers on the outer sides of a left stock rail and a right stock rail, sleepers on the inner sides of a left switch rail and a rightswitch rail, sleepers on the outer sides of two wing rails, and intersections of a frog center. The temperatures around the railway turnout are detected through the temperature sensors, and the rainand snow states of the railway turnout are detected through the rain and snow sensors. The heat conduction plates are laid on ballast beds below the stock rails, the switch rails, guide curve rails, the wing rails and the frog enter and are closely attached to steel rails and are controlled by the control boxes installed outside the stock rails, that is, when the temperature sensor set in a certain railway turnout detects that the temperature is smaller than 2 DEG C and the rain and snow sensor detects rain or snow at the position, a control circuit board judges that the freezing condition exists at the position and the left and right heat conduction plates are controlled by the control circuit board to conduct heating.

Description

technical field [0001] The invention relates to automatic ice and snow detection and rapid ice melting equipment for railway turnouts, in particular to a device for detecting and melting ice and snow on tip rails and basic rails of railway turnouts. Background technique [0002] Turnout is an important part of railway track and an indispensable important equipment for railway vehicles to transfer from one track line to another track line. It plays an indispensable role in railway transportation business. In winter, railway turnouts tend to freeze, especially the point where the point rail and the point rail meet the basic rail. Once it freezes, the gap between the point rail and the basic rail will be too large, causing train derailment accidents. [0003] In the prior art, there are two common ways to deal with the icing of railway turnouts. 1. Check whether there is ice or snow on the turnouts by employees along the line. When ice and snow are detected, manually sweep the ...

AI Technical Summary

Problems solved by technology

However, these two methods have the following problems and disadvantages: 1. It is a relatively traditional method for employees to check and remove snow along the line, but it requires more personnel and low operating efficiency, and it is not suitable for the situation where the snow freezes after melting; 2. 1. The method of processing with a blowtorch is to use a blowtorch with a small gas tank, burn it with fire, and evaporate the water to dryness, but this method has relatively low operating efficiency, requires many personnel, and has a heavy load.
