Description

Dumping car driving and lifting combined control system
Technical field
The utility model relates to the driving of a kind of dumping car and lifting combined control system.
Background technology
The a lot of vehicle of underground coal mine need have self-unloading function, as explosion-proof pipe car needs to be unloaded by the pipe in loading space with self-unloading function after appointed place transported to by pipe, mud in tank body need be poured out with self-unloading function by explosion-proof suction-type sewer scavenger, and lorry needs to be poured out by the material in loading space with self-unloading function after arriving and giving directions place.Because the size design of the vehicle used at underground coal mine must be less, cause the space of operator's compartment less, and the hand change over valve of Tipper Lifting oil cylinder generally all designs in operator's compartment, easy generation makes loading space or tank body lift when driving because of chaufeur maloperation elevating ram hand change over valve, and the places such as coal mine underground air door are highly lower, easily crash.
Utility model content
The purpose of this utility model is to propose one when dumping car is driven a vehicle, and the dumping car of loading space or tank body lifting can not be driven a vehicle and lifting combined control system by elevating ram.
For achieving the above object, the utility model takes following technical scheme: a kind of dumping car driving and lifting combined control system, comprise fuel tank, filter, Hydraulic Pump, safety valve, explosion-proof solenoid valve, hand change over valve, elevating ram, air control switch, flame proof power supply, gear selecting cylinder, gear selecting change-over valve, gas bag and block selecting maneuvering valve, gear selecting cylinder comprises piston rod, and block selecting maneuvering valve comprises joystick, the first pipeline be connected with the oil outlet of Hydraulic Pump, second pipe respectively with the oil inlet of safety valve, the oil inlet P mouth of explosion-proof solenoid valve is connected, the execution mouth A mouth of explosion-proof solenoid valve is connected with the oil inlet P mouth of hand change over valve, two of hand change over valve perform mouth A mouths and B mouth respectively with the rodless cavity of elevating ram, rod chamber connects, the power connection end of explosion-proof solenoid valve is connected described air control switch with between flame proof power supply, the execution mouth A mouth of described gear selecting change-over valve is respectively by the 3rd pipeline, the gas control mouth A mouth of the 4th pipeline and air control switch, the rodless cavity of gear selecting cylinder connects, the execution mouth B mouth of gear selecting change-over valve is connected with the rod chamber of gear selecting cylinder, the piston rod of described gear selecting cylinder is connected with the joystick of block selecting maneuvering valve, the admission port P mouth of gear selecting change-over valve is connected with gas bag, the oil inlet of Hydraulic Pump is all connected with fuel tank with the oil outlet of safety valve.
Elevating ram of the present utility model can not lifting in dumping car driving conditions, and the loading space therefore controlled by elevating ram or tank body can not be picked up, thus enables dumping car safely by coal mine underground air door equal altitudes lower ground side.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of driving and lifting combined control system.
Detailed description of the invention
Embodiment 1
This self-unloading driving and lifting combined control system comprise fuel tank 1, filter 2, Hydraulic Pump 3, safety valve 4, explosion-proof solenoid valve 5, hand change over valve 6, elevating ram 7, air control switch 8, flame proof power supply 9, gear selecting cylinder 10, gear selecting change-over valve 11, gas bag 12 and block selecting maneuvering valve 13, gear selecting cylinder 10 comprises piston rod 10-1, and block selecting maneuvering valve 13 comprises joystick 13-1.Elevating ram 7 is used for controlling the loading space of dumping car or the lifting of tank body.
The oil inlet of Hydraulic Pump 3 is connected with fuel tank 1 by filter 2, the first pipeline 14 be connected with the oil outlet of Hydraulic Pump 3, second pipe 15 are connected respectively and with the oil inlet of safety valve 4, the oil inlet P mouth of explosion-proof solenoid valve 5, the oil outlet of safety valve 4 is connected with fuel tank 1, the execution mouth A mouth of explosion-proof solenoid valve 5 is connected with the oil inlet P mouth of hand change over valve 6, and two of hand change over valve 6 perform mouth A mouths and B mouth and are connected with the rodless cavity of elevating ram 7, rod chamber respectively.The power connection end of described explosion-proof solenoid valve 5 be connected described air control switch 8 between flame proof power supply 9, the execution mouth A mouth of described gear selecting change-over valve 11 is connected with the gas control mouth A mouth of air control switch 8, the rodless cavity of gear selecting cylinder 10 respectively by the 3rd pipeline 16, the 4th pipeline 17, the execution mouth B mouth of gear selecting change-over valve 15 is connected with the rod chamber of gear selecting cylinder 14, the admission port P mouth of gear selecting change-over valve 11 is connected with gas bag 12, and the piston rod 10-1 of described gear selecting cylinder 10 is connected with the joystick 13-1 of block selecting maneuvering valve 13.
When dumping car needs forward travel, operation gear selecting change-over valve 11, the admission port P mouth of gear selecting change-over valve 11 is communicated with execution mouth A mouth, gas in gas bag 12 is divided into two tunnels after gear selecting change-over valve 11, the 4th pipeline 17 of leading up to enters in gear selecting cylinder 10, and the piston rod 10-1 promoting gear selecting cylinder 10 moves downward, because the piston rod 10-1 of gear selecting cylinder 10 is connected with the joystick 13-1 of block selecting maneuvering valve 13, thus drive manipulation valve rod 13-1 to move downward, complete the action selecting D Drive; The 3rd pipeline 16 of separately leading up to arrives the gas control mouth A mouth of air control switch 8, air control switch 8 is closed, P mouth and the A mouth of explosion-proof solenoid valve 5 are obstructed, explosion-proof solenoid valve 5 is in obtain electricity condition (as shown in Figure 1), under this state, the pressure oil of Hydraulic Pump 3 does not enter hand change over valve 6 by explosion-proof solenoid valve 5, the P mouth of hand change over valve 6 and A mouth, B mouth are all obstructed, without pressure oil input elevating ram 7, at this moment, even if maloperation hand change over valve 6, elevating ram 7 also can not action, and the compartment of dumping car can not lifting.
When dumping car is in dead ship condition, operation gear selecting change-over valve 11, its admission port P mouth is obstructed with execution mouth A, and the gas of gas bag 12 can not arrive gear selecting cylinder 10, the piston rod 10-1 of gear selecting cylinder 10 can only drive the joystick 13-1 upward movement of block selecting maneuvering valve 13, completes the action selecting neutral gear; Now the gas control mouth A mouth of air control switch 8 does not have gas to input, air control switch 8 is opened, explosion-proof solenoid valve 5 is in power failure state, at this moment the P mouth of explosion-proof solenoid valve 5 communicates with A mouth, the pressure oil of Hydraulic Pump 3 enters hand change over valve 6 by explosion-proof solenoid valve 5, operation hand change over valve 6, just can make elevating ram 7 action thus be lifted by the envelope of dumping car.
