Hydraulic railclamping braking system of mine endless rope winch

Abstract

A hydraulic holding rail braking system for a mine-used endless rope winch, comprising a vehicle axle, a control room fixed on the vehicle axle, and a brake holding rail assembly arranged at the bottom of the vehicle axle; it is characterized in that: The brake holding rail assembly includes: an ultra-speed centrifugal release device fixed at the bottom of the axle, a hydraulic holding rail device and a hydraulic transmission pipeline system. The braking system has automatic protection and manual protection functions. The brake adopts caliper hydraulic The rail-holding brake can be controlled manually or automatically, and is a fail-safe type. During operation, the brake caliper can be lifted above the rail surface, which is suitable for undulating common rail operation. When braking, the caliper brake hugs both sides of the rail head, which has high safety and reliability, and is worthy of large-scale application and promotion.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of a mining transport vehicle braking system, in particular to a hydraulic rail-holding braking system of a mining endless rope winch. Background technique [0002] In the prior art, the most common braking method used by rail locomotives is brake shoe braking. The tile-shaped brake block made of cast iron or other materials hugs the wheel tread tightly during braking and stops the wheel through friction. Rotation; In comparison, the newer braking method uses disc brakes, which are mainly installed on the axle or on the side of the wheel spoke plate, and the brake caliper is made of synthetic materials. The two brake pads press against the side of the brake disc to generate a braking force through friction to stop the rail vehicle from moving forward. [0003] The above two braking methods all use the friction force between the wheel and the track to achieve braking, which is e...

AI Technical Summary

Problems solved by technology

[0003] The above two braking methods use the friction between the wheel and the track to achieve braking, which is easy to wear the wheel and the track, and the maximum deceleration of this braking method is only μg (the friction coefficient of the track multiplied by its own weight)

If the traveling mechanism is required to achieve the acceleration, steady speed and deceleration process with a maximum speed of 5m / s in a short stroke, and the running mechanism is required to run smoothly, it is impossible to use the above technology
