Device for controlling temperatures of pole sole of magnetic track brake and track as well as control method thereof

Abstract

The invention discloses a device for controlling temperatures of a pole sole of a magnetic track brake and a track as well as a control method thereof. A first non-contact temperature sensor and a second non-contact temperature sensor are respectively used for detecting the temperature of the pole sole of the magnetic track brake and the steel track; a water through hole is formed in the side face of the pole sole of the magnetic track brake; small water spraying holes are formed at the bottom of the pole sole of the magnetic track brake; the water through hole and the small water spraying holes are communicated inside the pole sole of the magnetic track brake; the water through hole is connected with the lower part of a water tank in a sealed manner by passing through a spiral elastic hose and a first solenoid valve in sequence; a liquid meter is arranged in the water tank; the top of the water tank is communicated with atmosphere through a second solenoid valve; the side part of the water tank is connected with a water pipe connected on a train through a fourth solenoid valve; the side part of the water tank is sequentially connected with an air duct on the train through a one-way valve and a third solenoid valve in sequence; and the liquid meter and the solenoid valves are connected with an electronic control unit. The device provided by the invention can effectively cool the pole sole and the steel track, so that the excessive abrasion and the adhesive welding of the pole sole and the steel track can be prevented when the magnetic track brake works.

Description

technical field [0001] The invention relates to a magnetic rail brake pole shoe and rail temperature control device and a control method thereof, which belong to the technical field of rail vehicle braking technology. Background technique [0002] Magnetic track brakes are mainly composed of brake beams, suspension / lifting devices, magnets, pole shoes, etc. The working principle of the magnetic rail brake is to use the friction resistance generated when the brake pole shoe and the rail surface move relative to each other to decelerate, so as to achieve the purpose of braking. The braking process is a dynamic friction process. Its friction braking system is composed of pole shoes, rail surfaces and interface film. Friction converts the kinetic energy of the train into heat energy, and at the same time causes the temperature of the rail and pole shoes to increase and the wear to increase. . The high temperature generated during the friction process will have a huge impact on...
