Specific implementation mode
The present invention is described in further details in the following with reference to the drawings and specific embodiments.As shown in Figure 1, a kind of safety electricity
The pressure driving special integrated hydraulic power source of train re-railing equipment, including power supply 1, integrated hydraulic system 2, the first answer hydraulic cylinder 3-
1 and second multiple hydraulic cylinder 3-2.
As shown in Fig. 2, integrated hydraulic system 2 includes the motor 9 powered by power supply 1, and the low-pressure plunger driven by motor 9
Pump 8-1 and high-pressure plunger pump 8-2；The oil inlet of low-pressure plunger pump 8-1 and high-pressure plunger pump 8-2 is connected to by filter 10
The oil outlet of fuel tank 11, low-pressure plunger pump 8-1 is connected to the oil inlet and low pressure pilot relief valve 7- of low pressure check valve 6-1 simultaneously
1 oil inlet, the oil outlet of high-pressure plunger pump 8-2 are connected to oil inlet and the high pressure hydraulic control overflow of high pressure check valve 6-2 simultaneously
The oil inlet of valve 7-2；The oil outlet of high-pressure overflow valve 7-2 and low pressure pilot relief valve 7-1 is all connected to fuel tank 11；Low pressure is unidirectional
The oil outlet of valve 6-1 and high pressure check valve 6-2 are connected to an oil inlet of three position four-way directional control valve 5 simultaneously；3-position 4-way changes
The first is connected to by first throttle valve 4-1 to an oil outlet of valve 5 and answers hydraulic cylinder 3-1, three position four-way directional control valve 5 it is another
One oil outlet is connected to second multiple hydraulic cylinder 3-2 by second throttle 4-2.
The power supply 1 of the present embodiment is the accumulator of two 12V, and stable energy input is provided for integrated hydraulic power source.It adopts
With this energy-provision way it is safe and reliable, be readily transported, it is and of low cost, and the voltage of accumulator is only 12V, in safety electricity
Within pressure, danger when installation and operation is reduced.Certainly the also accumulator and electricity of replaceable disposable type according to actual needs
Machine matches.
Plunger pump includes that high-pressure plunger pump 8-2 and low-pressure plunger pump 8-1 so that equipment can be lightly loaded high-speed motion and heavy duty
Low-speed motion.
Motor, plunger pump, control valve and fuel tank are integrated, cumbersome installation process when having eliminated multiple, significantly
Improve the reliability of service efficiency and equipment.As shown in Fig. 3 Fig. 4, compact overall structure is light, the equipment operation letter after integrating
It is single, reduce human cost.
In order to meet the operation of large-tonnage, big stroke, oil reserve is insufficient, can otherwise designed fuel tank, or increase service tank.
The operation principle of hydraulic system is：
When return to work make when, accumulator 1 and motor 9 are run wires to, integrated hydraulic system 2 and two are risen multiple
Hydraulic cylinder is connected with oil pipe.After installing re-railing equipment, it is first turned on 9 power supply of motor, motor 9 is started to work, and high-pressure column is driven
Plug pump 8-2 and low-pressure plunger pump 8-1 pump oils.Due to just having started multiple hydraulic cylinder with the train that derails also not in contact with so liquid at this time
Cylinder pressure load is almost nil, and oil circuit pressure is low, and high-pressure overflow valve 7-2 and low pressure pilot relief valve 7-1 are in off state, hydraulic pressure
Oil flows to three position four-way directional control valve 5 through high pressure check valve 6-2 and low pressure check valve 6-1, and three position four-way directional control valve 5 is switched on one side
To any position of non-middle position, and the first throttle valve 4-1 on the side is opened, closes the second throttle 4-2 of another side.With beat
The first for the first throttle valve 4-1 connections opened answers hydraulic cylinder 3-1 setting in motions.Due to high-pressure plunger pump 8-2 and low-pressure plunger
Pump 8-1 has flow input, especially low-pressure plunger to pump 8-1, and flow is larger, so elongation speed is fast, makees low load high speed and transports
It is dynamic.When being elongated to a certain suitable position, open first throttle valve 4-1 is closed, stops answering hydraulic cylinder 3-1 to the first at this time
Fuel feeding, and pressurize.Three position four-way directional control valve 5 is switched to another side, and opens the second throttle 4-2 on the side.Then with
Second of two throttle valve 4-2 connections is multiple, and hydraulic cylinder 3-2 starts rapid elongation.Aforesaid operations are repeated and so that two are played multiple liquid
Cylinder pressure alternately extend, until with derailing vehicle contact.
After a multiple hydraulic cylinder is elongated to suitable position with derailing vehicle contact, multiple operation has been proceeded by.Due to it is de-
Start load after rail vehicle contact to start to become very large, the hydraulic pressure of oil circuit rapidly rises, due to low pressure pilot relief valve 7-1's
Control oil circuit is connected with high-pressure oil passage, so low pressure pilot relief valve 7-1 is connected, low pressure oil way and fuel tank are connected.It is low at this time
The not outside fuel feeding of hydraulic plunger pump 8-1, so the state is only done work by high-pressure plunger pump 8-2, the oil pressure that high-pressure plunger pump 8-2 is generated
Under high-pressure overflow valve 7-2 effect, hydraulic pressure setting safe pressure hereinafter, then flowing to three by high pressure check valve 6-2
Four-way reversing valve 5, at this time low pressure check valve 6-1 cut-offs.It is identical with operation when low load high-speed motion, so that two multiple hydraulic cylinders is handed over
Temporary substitute is made, and then jacks up derailing vehicle.Due to only having high-pressure plunger pump 8-2 to have flow input, flow is smaller, so playing multiple liquid
Cylinder pressure makees heavy-duty low-speed movement, and vehicle to be derailed rises to certain altitude, and the elongation by having controlled multiple hydraulic cylinder makes
The vehicle that derails adjusts above position to rail.
After derailing vehicle is moved to right over rail, two throttle valves are closed, during three position four-way directional control valve 5 is switched to
Position, is then shut off power supply 1, then adjusts two throttle valves, starts, to playing multiple hydraulic cylinder off-load, to put down derailing vehicle, complete
Multiple operation.
