Brake air pipe pressure detection device

Abstract

A brake air pipe pressure detection device disclosed by the present invention comprises a barometer, a fixing frame is fixedly arranged at the lower end of the barometer, a connecting pipe is fixedly arranged in the middle of the lower end of the barometer, a tensioning mechanism is arranged in the fixed frame, and the tensioning mechanism comprises a telescopic rod, a tensioning wheel, a connecting rod and a guide wheel; a plurality of telescopic rods are evenly and fixedly arranged on the side wall of the inner side of the fixing frame, tensioning wheels are movably arranged at the ends, away from the side wall of the inner side of the fixing frame, of the telescopic rods through rotating shafts, the outer portions of the tensioning wheels are attached to the outer side surfaces of the connecting pipes, and connecting rods are fixedly arranged on the two sides of the lower ends of the telescopic rods in the fixing frame. The brake air pipe pressure detection device is good in use effect, a high-speed train inspector can conveniently detect the pressure of a high-speed train brake air pipe, and meanwhile the connecting pipe for detection can be conveniently stretched when used and can be conveniently stored when not used.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a brake air pipe pressure detection device. Background technique [0002] The brake control device of each vehicle of the high-speed rail EMU is controlled by a microcomputer, which is composed of the electric brake (regenerative brake) of the motor car and the air brake (disc brake) of each car. [0003] When the vehicle brakes, it mainly passes through (press brakes, and the air pressure during braking affects the braking force. Therefore, considering the safety of vehicle braking, the detection of vehicle brake air pressure is essential for vehicle maintenance. However, the brake air pressure detection of the current vehicle will have the problems of cumbersome detection and complex structure of the detection device. Contents of the invention [0004] The object of the present invention is to provide a brake air pipe pressure detection device to solve the problems...

Problems solved by technology

[0003] When the vehicle brakes, it mainly passes through (press brakes, and the air pressure during braking affects the braking force. Therefore, considering the safety of vehicle braking, the detection of vehicle brake air pressure is essential for vehicle maintenance. , and the current brake pressure detection of vehicles will have the problems of cumbersome detection and complex structure of the detection device, which is troublesome to carry, time-consuming and labor-intensive, and more obstructive when carrying, which makes the brake pressure detection of vehicles more troublesome than other detection tasks
