Abstract

The invention provides a braking device, and relates to the technical field of braking. The braking device comprises a base provided with a through hole, a lock ring arranged on the wall of the through hole, and a driving device. A to-be-braked part passes through the through hole, and the lock ring is used for sleeving the to-be-braked part. When the to-be-braked part needs to be braked, becausethe lock ring is provided with a notch, a linear driving device is controlled to push one end part, with the notch, of the lock ring to approach to the other end part, so that the inner diameter of the lock ring is reduced, and the lock ring is tightly attached to the to-be-braked part to limit the to-be-braked part to stop moving or limit the to-be-braked part to move. The braking device can stopand brake the to-be-braked part for a long time, the automation is improved by controlling the driving device, the low-efficiency operation that an operator needs to tighten a brake system one by oneis avoided, and the application range of the braking device is improved.

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, rail 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 han...
