Abstract
A kind of railless free-wheeled vehicle power cutoff automatic parking system, comprise Parking Brake oil cylinder, Parking Brake, solenoid directional control valve, stopping brake change-over valve, energy storage, the oil inlet P mouth of described stopping brake change-over valve is connected with energy storage, the execution hydraulic fluid port A mouth of stopping brake change-over valve is connected with the oil inlet P mouth of flame proof solenoid directional control valve, the execution hydraulic fluid port B mouth of flame proof solenoid directional control valve is connected with Parking Brake oil cylinder, Parking Brake oil cylinder is connected with Parking Brake, and flame proof solenoid directional control valve and stopping brake change-over valve oil return inlet T mouth separately is all connected with oil sump.The utility model is provided with solenoid directional control valve, after locomotive starts, solenoid directional control valve obtains electric, stopping brake change-over valve dead electricity, pressure oil does not enter Parking Brake oil cylinder by solenoid directional control valve, so chaufeur forgets pull-up shutdown handle and cause slip by slope problem when effectively can avoid parking on ramp.
Description
Technical field
The utility model relates to railless free-wheeled vehicle power cutoff automatic parking system.
Background technology
At present, coal mine-used trackless rubber wheel vehicle does not generally have the measure of power cutoff automatic parking, when the temporary term stop of inclined shaft tunnel, once cause vehicle anti-slide owing to forgetting pull-up rim brake after chaufeur parking, can cause safety misadventure at underground coal mine.
Utility model content
The purpose of this utility model is to propose a kind of power cutoff automatic parking system, and when effectively can avoid parking on ramp, chaufeur forgets pull-up shutdown handle and cause slip by slope problem.
For achieving the above object, the utility model takes following technical scheme: this railless free-wheeled vehicle power cutoff automatic parking system comprises Parking Brake oil cylinder, Parking Brake, stopping brake change-over valve, energy storage, Parking Brake oil cylinder is connected with Parking Brake; Also comprise solenoid directional control valve, the oil inlet P mouth of described stopping brake change-over valve is connected with energy storage, the execution hydraulic fluid port A mouth of stopping brake change-over valve is connected with the oil inlet P mouth of flame proof solenoid directional control valve, the execution hydraulic fluid port B mouth of flame proof solenoid directional control valve is connected with Parking Brake oil cylinder, and flame proof solenoid directional control valve and stopping brake change-over valve oil return inlet T mouth separately is all connected with oil sump.
The utility model is provided with solenoid directional control valve, and solenoid directional control valve has two states: when solenoid directional control valve obtains electric, and energy storage carrys out brake off to Parking Brake oil cylinder fuel feeding; When solenoid directional control valve dead electricity, the in-oil cylinder hydraulic oil of Parking Brake is back to fuel tank, implements braking.After locomotive starts, solenoid directional control valve obtains electric, stopping brake change-over valve dead electricity, and pressure oil does not enter Parking Brake oil cylinder by solenoid directional control valve, so chaufeur forgets pull-up shutdown handle and cause slip by slope problem when effectively can avoid parking on ramp.The utility model belongs to fail safe, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
Embodiment 1
See Fig. 1, this railless free-wheeled vehicle power cutoff automatic parking system comprises Parking Brake oil cylinder 1, Parking Brake 2, solenoid directional control valve 3, stopping brake change-over valve 4, energy storage 5.
The oil inlet P mouth of described stopping brake change-over valve 4 is connected with energy storage 5, the execution hydraulic fluid port A mouth of stopping brake change-over valve 4 is connected with the oil inlet P mouth of solenoid directional control valve 3, the execution hydraulic fluid port B mouth of solenoid directional control valve 3 is connected with the rod chamber of Parking Brake oil cylinder 1, Parking Brake oil cylinder 1 is by the motion of the pressure oil control plunger of pressure itself spring and energy storage 5, Parking Brake 2 adopts multiple-piece closed brake device, the piston rod of Parking Brake oil cylinder 1 is connected with the axle of Parking Brake 2, the solenoid directional control valve 3 oil return inlet T mouth respective with stopping brake change-over valve 4 is all connected with oil sump.
Start diesel engine of locomotive, namely solenoid directional control valve 3 is energized after locomotive starts, P mouth and the B mouth of solenoid directional control valve 3 communicate, the handle of stopping brake change-over valve 4 is placed on " declutching " position by " parking " position, P mouth and the A mouth of stopping brake change-over valve 4 communicate, and from the pressure oil of energy storage through stopping brake change-over valve 4 and solenoid directional control valve 3, enter parking brake oil cylinder 2, moving plate in drg is separated with still, thus removes braking during standstill.After locomotive fulfils assignment, close key switch, locomotive stops working, car load power-off, and solenoid directional control valve power-off back valve core resets, and the oil return of B mouth, drg oil cylinder 2, under spring pressure effect, is reset to braking mode, realizes power cutoff automatic parking.Put to " parking " position by stopping brake change-over valve handle, when preventing next time from opening car, pressure oil directly enters parking brake brake off, causes locomotive automatic moving simultaneously.
