Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
As shown in Figure 1, the utility model is arranged in vehicle structure 19 framework, and air compressor 1 is by track laying machine electric set electric supply, and limit the compressed-air-storing of pressure in storage reservoir 2, air compressor 1 is arranged in the middle part of vehicle.The storage reservoir 2 of air compressor 1 connects with independent brake valve 15 pipeline through shutoff valve 43, oil water separator 4, dirt collector 5, non-return valve 6, and described independent brake valve 15 connects with application valve 9 through blast main 21, and application valve 9 connects with brake cylinder 12 through shutoff valve 1.
The radical function of oil water separator 4 is separated by the moisture of air compressor 1 when pressurized air in air, regulates compressed air pressure, be generally arranged on vehicle side frame inwall.
Independent brake valve 15, for the independent brake of track laying machine, alleviation, the braking of it and vehicle, is alleviated irrelevant, and also have automatic pressure-maintaining performance, can realize the independent release effect after car brakeing, independent brake valve 15 is arranged on operator's compartment simultaneously.
Application valve 9, by the control of independent brake valve 15, for inflation and the discharge of car brakeing cylinder 12, to make vehicle obtain braking and alleviate, is generally arranged on vehicle interior crossbeam.
Brake cylinder 12 adopts railway standard car brakeing cylinder, spring reset; During braking, change the air pressure that storage reservoir 2 or auxiliary reservoir 11 transport into mechanical thrust, brake cylinder 12 airduct connection function valve 9 or air diverter valve 10, be installed on car beam inwall.
When track laying machine autonomous operation needs braking, operation independent brake valve 15 is to retarder location, application valve 9 is opened, pressurized air in storage reservoir 2 is through shutoff valve 43, oil water separator 4, dirt collector 5, non-return valve 6, application valve 9, shutoff valve 1, enter brake cylinder 12, promote brake cylinder 12 internal piston and aerodynamic energy is transformed into mechanical energy, thus realize car brakeing.
When needing to alleviate after the braking of track laying machine autonomous operation, operation independent brake valve 15 is to alleviating position, and application valve 9 discharges the pressurized air in brake cylinder 12, realizes alleviating under the effect of brake cylinder 12 spring force.
Described brake cylinder 12 connects with air diverter valve 10 pipeline through braking earthen pipe 23, shutoff valve 28, and air diverter valve 10 connects with train pipe 13 through shutoff valve 3 20, and air diverter valve 10 also connects with auxiliary reservoir 11, and described train pipe 13 connects with brake hose 16.
Air diverter valve 10 is core components of rolling stock air brake, it acts on train pipe air pressure variations, there are the functions such as pressurization alleviation, pressure m, service lap, the auxiliary reservoir 11, the brake cylinder 12 that have train pipe 13 and connected by pipe that connect with it, be installed on car beam inwall.
Train pipe 13 is whole through vehicle, and its two ends and brake hose 16 are connected, and be connected to locomotive or other vehicle, middle part is connected with air diverter valve 10.
Shutoff valve 1, shutoff valve 28, shutoff valve 3 20, shutoff valve 43 are arranged between airline, for the pressure air cut off or in through pipeline, realize the needs of different change working.
Crosspointer compression indicator 14 is connected with, for showing blast main 21 and brake cylinder 12 inner air pressure between described blast main 21 and braking earthen pipe 23.
The emergency brake valve 17 of sudden stop is needed when being connected with safety hazard between described blast main 21 and effect pipe 22.When independent brake valve 15 needs sudden stop because of fault operation failure or other safety hazard, operation emergency brake valve 17 can realize emergency braking vehicle.
