Electronic readable-type ball for vehicle ball-passage test

Abstract

The invention relates to an electronic readable-type ball for a vehicle ball-passage test, which is characterized by comprising a solid ball body, wherein an external mark is disposed on the surface of the ball body, an electronic mark concentric with the ball body and a metal mark vertical to the electronic mark are disposed in the ball body, and the electronic mark and the metal mark are disposed at an interval. The ball body can be made from a thermoplastic polyester elastomer material, and integrally moulded with the electronic mark and the metal mark via injection process. The information of the code of a unit which uses the test ball and the sequence number of the test ball recoded by the external mark, the electronic mark and the metal mark is completely the same. When the external mark on the surface of the ball body cannot be identified due to wear, the information of the internal marks of the ball body can be read via an electronic information reading device or an X-ray transmissometer; and when the ball body is broken, identification can be directly performed by viewing the metal mark. Therefore, finding out the related information at any time, especially when an accident happens can be ensured, thus realizing liability traceability for the unit which uses the test ball.

Description

technical field [0001] The invention relates to a test ball, in particular to an electronically readable vehicle ball passing test ball used for a railway vehicle brake pipe resistance test. Background technique [0002] The vehicle ball passing test is the first step in the single vehicle braking test of the vehicle braking system. The purpose is to check whether the main brake system of the vehicle is unimpeded. During the test, put the test ball into the brake hose connector body at one end of the vehicle, connect the bicycle tester, and make the test ball pass through the brake main pipe from the brake hose at one end of the vehicle under the action of a certain amount of compressed air. If the brake hose and the other end of the brake hose are completely inserted into the test ball receiver, the ball passing test is qualified. [0003] The existing test ball is a solid nylon ball with a diameter of 25.4 mm, which has the disadvantages of poor wear resistance, unstable ...

AI Technical Summary

Problems solved by technology

In addition, in the ball passing test, if the test ball is missed in the brake pipe system or damaged in the brake pipe system, if it is not detected in time, it will cause a driving accident.

Since the existing test balls are only numbered on the surface of the ball, it is easy to be unrecognizable due to wear and tear during use, so there is no traceability to the user unit, making it difficult to find the responsible person after an accident

There was once a general class D accident in railway traffic. The test ball blocked the train pipe and caused the brake failure of the railway freight car. Because the test ball did not have a clear mark, it was impossible to determine the relevant responsible person.
