Problems solved by technology

[0004] In order to solve the problem that the vehicle bottom, skirt and other parts of the existing Q6W light rail vehicles are very close to the steel rails, making it difficult for the operator to drill under the vehicle, and at the same time, it is very difficult to directly pull the piston rod to relieve the pull ring to overcome its locking pressure. Difficult, the technical problem that the parking brake cylinder is not easy to be manually relieved, the invention provides a manual relief device for the parking brake cylinder of light rail vehicles

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Such as Figure 2 to Figure 6 As shown, the manual release device for the light rail vehicle parking brake cylinder of the present invention includes a lever mechanism 4 , a rope mechanism 5 and a pulley mechanism 6 . The lever mechanism 4 is integrally formed, which includes two lever arms 4-1 and a connecting seat 4-2. The front end of the lever arm 4-1 is a cam 4-1-1, and the cam 4-1-1 is provided with a shaft hole 4 -1-1-1. The two lever arms 4-1 are placed in parallel, and their tail ends are fixedly connected with the connecting seat 4-2, and the center of the connecting seat 4-2 is provided with a through hole 4-2-1.

[0016] The pulley mechanism 6 includes two pulley assemblies 6-1 and two brackets 6-2, and the two brackets 6-2 are placed parallel and vertically. The pulley assembly 6-1 includes a fixed pulley and a fixed shaft, the fixed pu...

Abstract

The invention discloses a manual release device for a parking brake cylinder of a light rail vehicle, and belongs to the field of manual release auxiliary devices for parking brake cylinders of railway vehicles. The manual release device comprises a lever mechanism, a rope mechanism and a pulley mechanism. By the aid of the pulley mechanism, the lever mechanism, a cam mechanism and the like, original extremely strenuous manual parking brake cylinder release operation in a lower narrow space of a train is changed into manual operation which can be easily completed inside a compartment. Operational reliability is enhanced while efficiency is improved, operation difficulty of operators is reduced, and potential safety hazards are eliminated. Besides, the manual release device for the parking brake cylinder of the light rail vehicle has the advantages of simple and practical structure, low cost, convenience in operation and popularization and the like.

Description

technical field [0001] The invention belongs to the field of manual relief auxiliary devices for parking brake cylinders of railway vehicles, and in particular relates to a manual relief device for parking brake cylinders of light rail vehicles. Background technique [0002] The light rail vehicle parking brake cylinder is a mechanical brake device that is relieved when inflated and applied when exhausted. Such as figure 1 As shown, the release device of the existing Q6W type light rail vehicle parking brake cylinder is a manual mode, and the manual release device is installed under the vehicle. 1, the through hole on the end of the piston rod 1-2 is fixedly connected with a piston rod release pull ring 3 through a pin 2. When the stopped train needs to release the braking state, the operator needs to come to the outside of the carriage and drill under the car body, pull the piston rod by hand to release the pull ring 3, so that it drives the piston rod 1-2 from the parkin...
