In impeller dynamic test, one of them important test event is placed in super sized type water tank by guide plate to test.This superhuge water tank, wide 3 meters, long 6 meters, weigh 132 tons when storing full water.In test process, water tank can require to fall after rise to ground in the flat surface from surface uplift to 3.2m and from flat surface, and be very difficult thing on water tank large and heavy for this span is from surface uplift to plane, especially, after water tank is lifted to flat surface, how to be fixed in flat surface by super large jumbo such for such as water tank is very difficult thing.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of plugging pin oil cylinder system with auto-lock function, by the mode of hydraulic pressure, super large jumbo being fixed in flat surface, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
There is a plugging pin oil cylinder system for auto-lock function, it is characterized in that:
Comprise fuel tank, four plugging pin oil cylinder and hydraulic pressure installation;
Described hydraulic pressure installation comprises by motor-driven gear pump, solenoid directional control valve, inserts formula relief valve, hydraulic lock, the first unidirectional adjustable restrictive valve, the second unidirectional adjustable restrictive valve;
The filler opening of described gear pump is connected to described fuel tank, the oil outlet of described gear pump is connected to the first hydraulic fluid port of described solenoid directional control valve and the filler opening of described slotting formula relief valve through one-way valve, second hydraulic fluid port of described solenoid directional control valve is connected to the reverse hydraulic fluid port of four groups of plugging pin oil cylinder through one of them one-way valve of described hydraulic lock, described first unidirectional adjustable restrictive valve, and the 3rd hydraulic fluid port of described solenoid directional control valve is connected to the forward hydraulic fluid port of plugging pin oil cylinder described in four groups through another one-way valve of described hydraulic lock, described second unidirectional adjustable restrictive valve;
4th hydraulic fluid port of described solenoid directional control valve is connected back described fuel tank with the oil outlet of slotting formula relief valve by return line.
The oil outlet of described one-way valve is connected with charge oil pressure sensor.
In the present invention, described return line is connected to cooler and filter in the location strings close to fuel tank.Described fuel tank has level meter, liquid level relay, air filter and temperature transducer.
The oil outlet of described one-way valve also connects and has pressure gauge.
Described first unidirectional adjustable restrictive valve and the second unidirectional adjustable restrictive valve are also connected with pressure gauge.
Adopt technique scheme, after super large jumbo is lifted to flat surface, on the support cylinder that hydraulic pressure installation can drive plugging pin oil cylinder to be stretched out by latch to be seated in and to be positioned in flat surface, thus super large jumbo reliably, is firmly fixed in the plane, and the self-locking of plugging pin oil cylinder can be achieved by hydraulic lock, ensure that plugging pin oil cylinder can not split away off from support cylinder.Therefore, the present invention have steadily, the advantage reliably super large jumbo is fixed in flat surface.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is hydraulic schematic of the present invention.
Embodiment
As shown in Figure 1, the plugging pin oil cylinder system with auto-lock function of the present invention, comprises fuel tank 1, four plugging pin oil cylinder 22 and hydraulic pressure installation 300.
Hydraulic pressure installation 300 comprise driven by motor 9 gear pump 10, solenoid directional control valve 163, insert formula relief valve 13, the unidirectional adjustable restrictive valve 272 of hydraulic lock the 19, first unidirectional adjustable restrictive valve 271, second.Hydraulic lock 19 is made up of two one-way valves, the forward hydraulic fluid port mutual induction of two one-way valves in hydraulic lock 19, as long as the forward hydraulic fluid port of one of them one-way valve has pressure to be opened, the forward hydraulic fluid port of another one one-way valve also can be opened by the pressure responded to simultaneously, and namely hydraulic lock 19 has two one-way valves and opens the function of simultaneously closing simultaneously.
The filler opening of gear pump 10 is connected to fuel tank 1 through ball valve 152, the oil outlet of gear pump 10 is connected to the first hydraulic fluid port of solenoid directional control valve 163 and the filler opening of slotting formula relief valve 13 through one-way valve 112, second hydraulic fluid port of solenoid directional control valve 163 is connected to the reverse hydraulic fluid port of four plugging pin oil cylinder 22 through one of them one-way valve of hydraulic lock 19, the first unidirectional adjustable restrictive valve 271, and the 3rd hydraulic fluid port of solenoid directional control valve 163 is connected to the forward hydraulic fluid port of four plugging pin oil cylinder 22 through another one-way valve of hydraulic lock 19, the second unidirectional adjustable restrictive valve 272.
4th hydraulic fluid port of solenoid directional control valve 163 is connected oil sump tank 1 with the oil outlet of slotting formula relief valve 13 by return line.
The oil outlet of the first unidirectional adjustable restrictive valve 271 and the oil outlet of the second unidirectional adjustable restrictive valve 272 are also connected with pressure gauge 17.The oil outlet of one-way valve 112 is also connected with charge oil pressure sensor 146 and pressure gauge 17.
The working method of this hydraulic pressure installation 300 is: gear pump 10 to hydraulic pressure installation 300 fuel feeding, inserts formula relief valve 13 for setting the oil pressure entering hydraulic pressure installation 300 under motor 9 drives.
Solenoid directional control valve 163 also has two kinds of getting types: when the first hydraulic fluid port of solenoid directional control valve 163 is communicated with the second hydraulic fluid port, when 3rd hydraulic fluid port is communicated with the 4th hydraulic fluid port, hydraulic oil then enters from the reverse hydraulic fluid port of four plugging pin oil cylinder 22, drives plugging pin oil cylinder 22 to retract to be separated with support cylinder 21.When the first hydraulic fluid port of solenoid directional control valve 163 is communicated with the 3rd hydraulic fluid port, when the second hydraulic fluid port is communicated with the 4th hydraulic fluid port, hydraulic oil then enters from the forward hydraulic fluid port of four plugging pin oil cylinder 22, drives plugging pin oil cylinder 22 to extend can be seated on the support cylinder in flat surface.
And when the 3rd solenoid valve selector valve 163 ends, two one-way valves all can end in hydraulic lock 19, thus the hydraulic oil of plugging pin oil cylinder 22 piston both sides can not be flowed, thus make plugging pin oil cylinder 22 hold mode.
Return line is connected to cooler 23 and filter 24 close to the location strings of fuel tank 1.
Fuel tank 1 has level meter 3, liquid level relay 4, air filter 5 and temperature transducer 6.
Can be found out by foregoing detailed description, the present invention has steadily, the advantage reliably super large jumbo is fixed in flat surface.
