Abstract
The utility model provides a colliery support carrier emergency stop apparatus, has hand -operated direction valve, energy storage ware and parking brake, and parking brake includes brake cylinder, gas bag, stop valve, installs the emergency stopping button valve on the driver's cabin instrument face plate and control hydraulic directional control valve with the gas of the adjacent installation of parking brake, the gas bag passes through the stop valve and is connected with the air inlet NO mouth of emergency stopping button valve, the gas outlet OUT mouth of emergency stopping button valve is connected with gas accuse hydraulic directional control valve's a gas accuse mouthful K mouth, the oil inlet P mouth and the energy storage ware of hand -operated direction valve are connected, the working hole A mouth and gas accuse hydraulic directional control valve's the oil inlet P mouth of hand -operated direction valve are connected, gas accuse hydraulic directional control valve's working hole B mouth is connected with the pole chamber that has of brake cylinder, gas accuse hydraulic directional control valve's oil return opening T mouth, the oil return opening T mouth of hand -operated direction valve is all connected with the oil tank. The utility model discloses only need can realize emergency stop with pressing the emergency stopping button valve, brake fastly.
Description
Technical field
The utility model relates to colliery bracket carrier lugs.
Background technology
Colliery bracket carrier is the vehicle of transporting supports on down-hole combined mining working, so have requirement to sudden stop.At present, the sudden stop of bracket carrier is the oil cylinder directly being controlled parking brake by shut-off valve.Shut-off valve is hand change over valve or manual apportioning valve.In transporting supports process, when needing sudden stop, chaufeur realizes sudden stop by the handle pulled on shut-off valve, but because the operating time of pulling handle needs 2-3 second, and the hydraulic oil in parking brake brake cylinder is back to fuel tank by shut-off valve, the draining time is relatively long, and these all directly affect sudden stop speed.
Summary of the invention
The purpose of this utility model is to propose a kind of colliery bracket carrier emergency stop mechanism that can improve sudden stop speed.
For achieving the above object, the utility model takes following technical scheme:
A kind of colliery bracket carrier emergency stop mechanism, there is hand change over valve, energy storage and parking brake, parking brake comprises brake cylinder, also has gas bag, shutoff valve, is installed on the pneumatic control hydraulic reversing valve of emergency stop push button valve on bridge instrumentation panel and installation adjacent with parking brake; Gas bag is connected with the admission port NO mouth of emergency stop push button valve by shutoff valve, the air extractor duct OUT mouth of emergency stop push button valve is connected with the gas control mouth K mouth of pneumatic control hydraulic reversing valve, the oil inlet P mouth of hand change over valve is connected with energy storage, the working hole A mouth of hand change over valve is connected with the oil inlet P mouth of pneumatic control hydraulic reversing valve, the working hole B mouth of pneumatic control hydraulic reversing valve is connected with the rod chamber of brake cylinder, and the oil return inlet T mouth of pneumatic control hydraulic reversing valve, the oil return inlet T mouth of hand change over valve are all connected with fuel tank.
The utility model has following good effect: the utility model only needs with pressing the emergency stop push button valve be installed on bridge instrumentation panel, and the in-oil cylinder hydraulic oil of stopping brake is back to fuel tank by Pneumatic reversal valve, can realize sudden stop.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Embodiment 1
See Fig. 1, the present embodiment has gas bag 1, shutoff valve 2, emergency stop push button valve 3, parking brake 4, pneumatic control hydraulic reversing valve 5, hand change over valve 6 and energy storage 7.
Gas bag 1 is connected with the admission port NO mouth of emergency stop push button valve 3 by shutoff valve 2, the air extractor duct OUT mouth of emergency stop push button valve 3 is connected with the gas control mouth K mouth of pneumatic control hydraulic reversing valve 5, the oil inlet P mouth of hand change over valve 6 is connected with energy storage 7, the working hole A mouth of hand change over valve 6 is connected with the oil inlet P mouth of pneumatic control hydraulic reversing valve 5, the working hole B mouth of pneumatic control hydraulic reversing valve 5 and the rod chamber of parking brake 4 are connected, and pneumatic control hydraulic reversing valve 5 is all connected with fuel tank with the oil return inlet T mouth of hand change over valve 6.
Above-mentioned emergency stop push button valve is installed on bridge instrumentation panel, pneumatic control hydraulic reversing valve installation adjacent with parking brake.
When parking brake 4 is in brake release state, the A mouth of hand change over valve 6 communicates with the P mouth of pneumatic control hydraulic reversing valve 5, and the B mouth of control hydraulic directional control valve 5 communicates with the rod chamber of stopping brake oil cylinder 4-1, and stopping brake oil cylinder 4 has been in pressure condition.During orderly shutdown, pilot control hand change over valve 6, hand change over valve 6 commutates, and the hydraulic oil in stopping brake oil cylinder 4-1 is back to fuel tank by control hydraulic directional control valve 5.
If need sudden stop in bracket carrier driving process, chaufeur can be pressed very rapidly and be installed on emergency stop push button valve on bridge instrumentation panel, pneumatic control hydraulic reversing valve 5 controls the commutation of gas port decompression rear valve body, hydraulic oil in stopping brake oil cylinder 4 is back to fuel tank fast by Pneumatic reversal valve 5, parking brake braking, can realize sudden stop and stopping speed is very fast.Because pneumatic control hydraulic reversing valve is adjacent with parking brake, the oil circuit that the hydraulic oil of parking brake gets back to fuel tank by pneumatic control hydraulic reversing valve is very short, and draining is very fast, contributes to improving stopping speed.
