A railway locomotive vehicle foundation braking device and its manual release device

Abstract

The invention discloses a manually relieving device of a foundation brake rigging of a railway rolling stock. The lower end of a traction component (1) of the manually relieving device is vertically arranged and connected with a ratchet pin component (3) through a conversion component (2); the conversion component (2) converts the vertical movement of the traction component (1) into the longitudinal movement of the ratchet pin component (3); and the upper end of the traction component (1) is connected with a framework (200) of the railway rolling stock. With the adoption of the structure, an operator can relieve braking only through pulling a handle (16) at the upper end of the traction component (1) mounted on the framework (200), therefore, remote control of the ratchet pin component (3) is achieved, and the operation convenience and safety are improved greatly. The invention further discloses the foundation brake rigging of the railway rolling stock, which comprises the manually relieving device and has the same effects.

Description

technical field [0001] The invention relates to the technical field of railway locomotive braking, in particular to a railway locomotive foundation braking device and a manual release device thereof. Background technique [0002] In order to ensure the parking braking force requirements of the rolling stock in the depot or on the ramp, the foundation braking device of the railway rolling stock is usually equipped with a parking braking device. The parking braking device usually includes a spring energy storage mechanism, which is provided by the spring when the rolling stock is parked. required braking force. In order to ensure that the rolling stock can be dragged under the condition of no total wind (for example, the air compressor of the rolling stock does not work, and the main air cylinder has no wind pressure), the foundation brake device is usually equipped with a manual release device, whose function is to completely relieve the parking load. The spring parking brak...

Problems solved by technology

[0004] like figure 1 As shown, in the prior art, the manual relief device 100' is usually located under the bogie. When it is necessary to release the parking braking force, the operator needs to bring his own tools and drill under the bogie to pull the manual relief device 100' for relief. The operation is very difficult. Inconvenient, especially for rolling stock on the third rail, it brings great safety hazards to operators
