A braking shuttle car system for a mine-used endless rope winch

Abstract

A novel brake shuttle vehicle system of a mining endless rope winch comprises a vehicle bridge, an operating room, a control box and a brake holding rail assembly, wherein the control room is fixedly connected with the vehicle bridge; the control box is arranged on the operating room and is used for controlling a hydraulic transmission pipeline system; the brake holding rail assembly is arranged at the bottom of the vehicle bridge. The novel brake shuttle vehicle system of the mining endless rope winch is characterized in that the brake holding rail assembly comprises an overspeed protection device, a hydraulic holding rail device and the hydraulic transmission pipeline system; the overspeed protection device is fixedly connected with the bottom of the vehicle bridge; a brake system has automatic protection and manual protection functions; a brake adopts pliers-type hydraulic holding rail brake, can be controlled manually and automatically, and is a fail safety type. During operation, brake pliers can be lifted off the rail surface, so the novel brake shuttle vehicle system is suitable for up-and-down common rail operation. During braking, pliers-type brake holds the two sides of the rail head, so the novel brake shuttle vehicle system is high in safety, high in reliability and worthy of large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of a braking system for mining transport vehicles, in particular to a novel braking shuttle car system for 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 ...

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
