A self-running mine car deceleration device

Abstract

The invention discloses a reduction gear of a gravity haulage mine car. The reduction gear comprises an electric control part and a mechanical part, wherein the electric control part comprises a circuit breaker, a contactor, a thermal relay, a first relay, a second relay, a first time relay, a second time relay, a first proximity switch, a second proximity switch and a motor, wherein the first proximity switch is used for detecting the position of the mine car; the second proximity switch is used for resetting a car blocking plate; when the mine car reaches the first proximity switch, the first proximity switch detects that the mine car reaches, the first time relay begins working, a coil of the contactor is electrified through set time relay, the contactor is closed, the motor begins running, and the car blocking plate moves downwards; when the car blocking plate returns to the highest point through one cycle, the second proximity switch detects that the car blocking plate returns to an original state, the coil of the contactor loses power, and the motor stops running, the car blocking plate is reset and waits for a next mine car; the mechanical part comprises a drive part and a resistance device part.

Description

[0001] Technical field: [0002] The invention relates to the field of mine cars, in particular to a self-running mine car deceleration device. Background technique [0003] In the prior art, the narrow-gauge railway transport vehicles used for conveying bulk materials such as coal, ore and waste rock in self-slipping mines in metal and non-metallic mine ring yards generally must be pulled by locomotives or winches, but self-slipping mine cars The system will have the following problems: the self-sliding car in the circular yard will collide with and damage the mine car when it arrives at the designated location due to different car conditions, and the mine car will fall off the road due to its self-slipping speed being too fast. [0004] Invention content: [0005] The object of the present invention is to provide a self-running mine car deceleration device, which solves the above-mentioned problems in the prior art. A self-running mine car deceleration device implementing ...
