Passive braking system of mining transportation equipment

Abstract

The invention discloses a passive braking system of mining transportation equipment. A main sprocket is mounted on a driving shaft and connected with auxiliary sprockets through a chain, the auxiliary sprockets are connected with a centrifugal clutch through a booster engine, the centrifugal clutch is connected with a stop valve, one end of the stop valve is connected with a brake cylinder while the other end is connected with an oil tank, the brake cylinder is mounted at the pliers handle end of a pliers type damper brake, a pressing shaft is mounted at the pliers handle end of the pliers type damper brake, and disc springs are mounted on the pressing shaft. An oil inlet pipe of the manual pump is connected with the oil tank, an oil outlet pipe is connected with the brake cylinder, an energy accumulator is connected on the oil outlet pipe of the manual pump, and a pressure gauge is connected on an oil pipe between the energy accumulator and the brake cylinder. The passive braking system has the technical advantages that passive braking can be realized, in other words, additional external power such as a motor is omitted; difficulty in maintenance can be lowered, few control valve banks are adopted, and leakage of hydraulic oil is less relatively; speed transmission is realized through positive driving of the booster engine, the sprockets and the centrifugal clutch, strength is higher, and difficulty and cost of maintenance are further lowered; due to a passive mode, explosion risk factors are avoided, and safety is higher; a pressure supplementing device is arranged, so that time of safety operation of the system is prolonged.

Description

technical field [0001] The invention relates to a braking system of mining transport equipment. Background technique [0002] At present, the braking system of traditional rail transportation equipment is to drive the pump to rotate directly through the wheels, and then brake the equipment through a series of valve groups. Because this braking control method uses a large number of valve groups, there are many brake systems. There are many leakage points and corresponding maintenance points, which increases the difficulty of equipment maintenance, and also brings a lot of trouble to maintenance personnel, and the cost also increases accordingly. And there is no supplementary pressure measure, resulting in a shorter safe running time of the system. Contents of the invention [0003] The purpose of the present invention is to provide a passive braking system for mining transport equipment [0004] The technical solution of the present invention is a passive braking system f...

Because this braking control method uses a large number of valve groups, there are many brake systems. There are many leakage points and corresponding maintenance points, which increases the difficulty of equipment maintenance, and also brings great trouble to maintenance personnel, and the cost also increases accordingly.
