Abstract

The invention provides a braking device, which relates to the technical field of braking, comprising: a base provided with a through hole, a lock ring provided on the wall of the through hole, and a driving device. The component to be braked passes through the through hole, and the lock ring is used to sleeve on the component to be braked. When the brake part needs to be braked, because the lock ring has a gap, the control linear drive device will push the end of the lock ring with the gap to the other end, thereby reducing the inner diameter of the lock ring and making it tightly attached to the brake ring. on the moving part to limit the stopping of the part to be braked or to limit the movement of the part to be braked. This braking device can stop and brake the brake parts for a long time, and by controlling the driving device, the automation is improved, which avoids the low-efficiency operation that requires the operator to tighten the braking system one by one, and at the same time improves the braking performance of the braking device. scope of application.

Description

technical field [0001] The present invention relates to the technical field of braking, in particular to a braking device. Background technique [0002] With the rapid development of my country's economy, commodity trade presents the characteristics of large quantity and intensive exchanges. When it comes to transporting large quantities of goods over long distances, traditional cars are no longer sufficient. Therefore, railway freight has become the main mode of transportation. [0003] In the existing braking system of railway freight cars, two sets of braking systems of a brake cylinder and a hand brake are configured. Among them, the brake cylinder mainly completes the speed control braking during the driving process until the vehicle stops, while the hand brake is mainly used in trucks that need to stay on the slope for a long time. In order to avoid the brake cylinder braking for a long time Leakage occurs naturally and the braking effect is lost. At this time, the ...
