Description

Technical Field

[0001] The utility model relates to the technical field of train equipment, in particular to a test ball receiving device. Background Art

[0002] The "Rules for Inspection and Maintenance of Railway Passenger Car Braking Devices" requires that after the completion of railway passenger cars, a single-car braking test should be carried out, including a ball test, with the focus on checking the continuity of the brake main line. During the ball test, the test ball enters from one end of the vehicle main line and is ejected from the other end to be qualified. When the test ball is ejected, in order to avoid its loss, a receiver must be installed on the upper part of the vehicle-end hose connector to ensure that all test balls enter the receiver when they are ejected. At present, during the ball test, a nylon mesh bag with a tightened end is usually directly installed on the upper part of the vehicle-end hose connector, and the installation is random and not firm.
