The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model gas-liquid systems figure;
Fig. 2 is the utility model structural representation;
Fig. 3 is brake cylinder brake structure figure.
Among the figure: 1, brake cylinder; 2, Centrifugal Releaser; 3, gas-liquid systems; 31, pressurized cylinder; 32, compressed air line; 33, air-pressure gauge; 34, energy storage; 35, change-over valve; 36, directional control valve; 37, pressure-gradient control valve; 371, by pass valve; 372, inserted valve; 4, connecting rod; 5, band-type brake.
The specific embodiment
As depicted in figs. 1 and 2, a kind of mining aerobraking shuttle car is equipped with a plurality of brake cylinders 1 that are used to brake in shuttle base, and Centrifugal Releaser 2 is installed on the shuttle car wheel; Installation gas-liquid systems 3 and gas-liquid systems 3 are connected with a plurality of brake cylinders 1, Centrifugal Releaser 2 on shuttle car.Above-mentioned gas-liquid systems 3 comprises a pressurized cylinder 31, and an end of pressurized cylinder 31 is connected with compressed air line 32, and the other end is connected with the pressure-gradient control valve 37 that pressurized cylinder 31 is carried out voltage stabilizing, pressure regulation; Described pressure-gradient control valve 37 is made up of by pass valve 371 and the inserted valve 372 that is connected on by pass valve 371 import and exports, and the control port of inserted valve 372 is connected with pressurized cylinder 31.This gas-liquid systems also has a plurality of directional control valves 36, and pressurized cylinder 31 is connected with energy storage 34 by a directional control valve 36; Connect a change-over valve 35 on the energy storage 34; Change-over valve 35 is connected with a plurality of brake cylinders 1 by both direction control cock 36; Directional control valve 36 in the whole gas-liquid systems all adopts inserted valve; Can reduce system's leakage of oil like this.Above-mentioned Centrifugal Releaser 2 is connected with the spool of change-over valve 35, and change-over valve 35 adopts two-position four-way valve.Discharge when regulating Centrifugal Releaser 2 to the speed set, Centrifugal Releaser just can promote the two-position four-way valve in the hydraulic efficiency pressure system.In order clearly to understand the pressure of pressurized cylinder 31, on pressurized cylinder 31, also be connected with the air-pressure gauge 33 that is used to show pressurized cylinder 31 pressure.
As shown in Figure 3, brake cylinder 1 adopts the form of band-type brake to brake, and is connected with two connecting rods 4 on each brake cylinder 1, is connected with band-type brake 5 on each connecting rod 4.Brake cylinder 1 adopts the form of band-type brake, and in the time of shuttle car stall or disconnected rope, brake cylinder 1 pressure descends rapidly, and the brake cylinder friction lining can be embraced track, reaches the purpose of safety arrestment.
Principle of work: in the time of shuttle car stall, because Centrifugal Releaser links to each other with the shuttle car wheel shaft, discharge when regulating Centrifugal Releaser to the speed of setting, Centrifugal Releaser can promote the two-position four-way valve in the gas-liquid systems.Thereby the pressure in brake cylinder piston cylinder chamber is linked to each other with liquid return hole, and brake-cylinder pressure reduces to 0, and brake cylinder is embraced track under the effect of dish spring, play brake action.After the braking, at first get rid of the transportation fault, be the pressurized cylinder inflation by compressed air line then, the pressurized cylinder booster cavity fills hydraulic oil, after the hydraulic oil supercharging, reopen brake cylinder, shuttle car can continue operation, and when the shuttle car normal transport, inserted valve plays the check valve effect, hydraulic coupling is locked in the brake cylinder piston rod chamber, and brake cylinder is an open mode.Under the normal operating condition, the gas end of pressurized cylinder does not need to connect compressed air line.
