Problems solved by technology

[0003] At present, the hand brakes for domestic vehicles to achieve parking braking have the following defects: the braking force depends on the strength of the operator, which results in a high degree of dependence on the operator. If the operator's strength is small, it will not be able to fully Braking; and the operator forgets to release the hand brake before the vehicle is running, which will cause the tread and the wheel to not be disengaged, resulting in scuffing of the tread, etc.

Abstract

The invention provides a brake parking cylinder manual relieving mechanism and a railway vehicle braking parking cylinder device, and belongs to the technical field of rail transit vehicle braking. The brake parking cylinder manual relieving mechanism comprises a mounting base, a taper shank and a relieving screw, wherein the taper shank and the relieving screw are arranged in the mounting base, one end of the taper shank extends out of the mounting base, and the taper shank can move in the axial direction of the taper shank in the mounting base; a plurality of pin holes penetrating through the circumferential wall of the mounting base are formed in the circumferential wall of the mounting base in the direction perpendicular to the axis of the taper shank, a clamping pin is arranged in each pin hole, one end of each clamping pin is provided with a state abutting against the taper surface of the taper shank, and each clamping pin is provided with a clamping pin spring in a sleeved mode;and the relieving screw is used for being connected to an external connection component. In the parking braking state, the force is transmitted to the external connection component through pulling the taper shank and the relieving screw, so that a locking mechanism of the external connection component is relieved, and the relieving state can be kept.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicle braking, in particular to a brake parking cylinder manual release mechanism and a railway vehicle brake parking cylinder device. Background technique [0002] The braking system of railway vehicles is usually equipped with a set of brake cylinders and a set of hand brakes. The brake cylinders complete the service braking (normal braking, emergency braking). The hand brake is usually used in the following situations Use when parking: If the vehicle needs to stay on the ramp for a long time during operation, in order to prevent the leakage of the brake cylinder and naturally alleviate the loss of braking effect, tighten the hand brake at this time; stop on the ramp to prevent rolling accidents , you need to tighten the hand brake; to prevent the vehicle from being blown away by the strong wind, you need to tighten the hand brake. [0003] At present, the hand brakes for domestic vehicl...
