Description

Brake shoe pressure static detection device

Technical Field

The utility model relates to a static detection device of brake shoe pressure for railway vehicle's brake shoe pressure is gathered, is saved, and the requirement, test method and the inspection rule of the vehicle brake shoe force test of regulation in "about railway freight car static brake shoe pressure experiment technical condition" are designed according to the ministry of transportation of the people's republic of China railway.

Background

Along with the development of society, the safety degree of railway transportation is far higher than that of air transportation and road transportation, and the railway transportation becomes the first-choice vehicle for most people to go on long journey, the detection and maintenance of vehicles become the central importance of safety guarantee work, and the detection of braking system is the first process of vehicle detection, whether normal work of braking system directly relates to whether the vehicle can run safely, the detection of the prior railway vehicle braking system is the detection of artificial striking, because the vehicle volume is larger, the detection is very complicated and fussy, a lot of inconvenience is brought to workers, and the safe running of the vehicle can not be guaranteed due to the reason of artificial detection.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a static detection device for brake shoe pressure, which adopts a distributed test scheme of an upper computer and a lower computer, wherein the lower computer is responsible for the data acquisition of a pressure sensor and is in wireless connection with the upper computer through a 485 communication module and a wireless module, so as to realize the data communication of control and acquisition; the host computer is 1 notebook computer, be responsible for carrying out the communication and the control testing process of pressure detection data with the next computer, manage and print the detection data, fully realize the convenience of test system use and the centralization of data, the sensor that test system adopted is high accuracy, it is ultra-thin, the authenticity, the accuracy of brake shoe pressure have fundamentally been guaranteed to the design scheme that two points gathered simultaneously in the test process, only need in the test process put the brake shoe of vehicle and wheel gap with the sensor can, easy operation is convenient, practice thrift manpower and materials, easy maintenance.

In order to achieve the above object, the present invention provides the following technical solutions:

a static brake shoe pressure detection device is characterized in that the whole machine consists of a notebook computer (7), a PLC (1), an AD041 analog quantity acquisition module (2), a wireless transmission module (3), a 24V power supply (4) and a brake shoe pressure sensor (6); the 24V power supply (4) converts an external 220V voltage into a 24V voltage to supply power to the sensor; the brake shoe pressure sensor (6) is placed in a gap between a brake shoe and a wheel of a vehicle to collect pressure; the AD041 analog quantity acquisition module (2) acquires the numerical value of each brake shoe pressure sensor (6); the PLC (1) is connected with the AD041 analog quantity acquisition module (2) and is used for controlling the acquisition of sensor data; the wireless transmission module (3) is a management center for data transmission and reports the acquired data to a program of a notebook computer (7); the notebook computer (7) can store, inquire and print test data.

The device has reasonable design, compact structure, advanced process, simple and convenient operation, stable operation and higher automation degree, and is intelligent equipment for detecting the pressure of the brake shoe of the railway vehicle; the main characteristics are as follows:

1. the equipment has reasonable process flow and high testing efficiency;
