For achieving the above object, the utility model adopts following technical scheme, the utility model comprises hydraulic lifting machine and hydraulic power unit, its structural feature hydraulic lifting machine is provided with each two of double acting single-piston rod master cylinder and single-acting single-piston rod auxiliary oil cylinders, and a double acting single-piston rod master cylinder adopts the synchronous connection mode of connect to form one with a single-acting single-piston rod auxiliary oil cylinder to overlap independent oil cylinder; The double acting single-piston rod master cylinder of the independent oil cylinder of two covers and the cross arrangement of single-acting single-piston rod auxiliary oil cylinder are in the both sides of hydraulic lifting machine, two double acting single-piston rod master cylinders of hydraulic lifting machine are provided with explosion relief valve, and explosion relief valve links to each other with hydraulic power unit by conduit.

The beneficial effects of the utility model:

Because the utility model hydraulic lifting machine is provided with each two of double acting single-piston rod master cylinder and single-acting single-piston rod auxiliary oil cylinders, a double acting single-piston rod master cylinder adopts the synchronous connection mode composition one of connect to overlap independent oil cylinder with a single-acting single-piston rod auxiliary oil cylinder; The double acting single-piston rod master cylinder of the independent oil cylinder of two covers and the cross arrangement of single-acting single-piston rod auxiliary oil cylinder are in the both sides of hydraulic lifting machine, two double acting single-piston rod master cylinders of hydraulic lifting machine are provided with explosion relief valve, explosion relief valve links to each other with hydraulic power unit by conduit, and hydraulic power unit is provided with unloading electromagnetic valve and check valve; , guaranteed safety so the lifting machine did not descend after but actv. was guaranteed the oil pipe explosion.

Description of drawings:

Fig. 1 is a hydraulic lifting machine structural representation of the present utility model;

Fig. 2 is a hydraulic power unit structural representation of the present utility model;

Fig. 3 is an oil channel structures scheme drawing of the present utility model.

The specific embodiment:

The utility model comprises hydraulic lifting machine 5 and hydraulic power unit 7, hydraulic lifting machine 5 is provided with double acting single-piston rod master cylinder 4 and single-acting single-piston rod auxiliary oil cylinder 3 each two, and a double acting single-piston rod master cylinder 4 adopts the synchronous connection mode of connect to form one with a single-acting single-piston rod auxiliary oil cylinder 3 to overlap independent oil cylinder; The double acting single-piston rod master cylinder 4,2 of the independent oil cylinder of two covers and 3,1 cross arrangement of single-acting single-piston rod auxiliary oil cylinder are in the both sides of hydraulic lifting machine 5, two double acting single-piston rod master cylinders 4,2 of hydraulic lifting machine 5 are provided with explosion relief valve F1, F2, and explosion relief valve F1, F2 link to each other with hydraulic power unit 7 by conduit.

As Fig. 2, shown in Figure 3, described hydraulic power unit 7 comprises Hydraulic Pump E, motor M, fuel tank H, unloading electromagnetic valve D1, D2, D3, check valve X, compression indicator Y, ball valve Q1, Q2, flow regulating valve J, oil filter G and by pass valve L, motor M links to each other with Hydraulic Pump E, and the end of Hydraulic Pump E links to each other with fuel tank H by oil filter G; The other end of Hydraulic Pump E links to each other with the lower end of check valve X, the end of by pass valve L respectively, the other end of by pass valve L links to each other with fuel tank H, the upper end of check valve X links to each other with the upper end of compression indicator Y, the first unloading electromagnetic valve D1, the lower end of the second unloading electromagnetic valve D2, the lower end of the 3rd unloading electromagnetic valve D3, the lower end of the first ball valve Q1 and the lower end of the second ball valve Q2 respectively, and the lower end of the first unloading electromagnetic valve D1 links to each other with fuel tank H by flow regulating valve J; The explosion relief valve F1 of the upper end of the described second unloading electromagnetic valve D2 same double acting single-piston rod master cylinder 4 links to each other, the upper end of the 3rd unloading electromagnetic valve D3 links to each other with the explosion relief valve F2 of another double acting single-piston rod master cylinder 2, the rodless cavity of the same single-acting single-piston rod auxiliary oil cylinder 3 of upper end difference of the first ball valve Q1 and the rod chamber of a double acting single-piston rod master cylinder 2 link to each other, and the upper end of the second ball valve Q2 links to each other with the rodless cavity of another single-acting single-piston rod auxiliary oil cylinder 1 and the rod chamber of another double acting single-piston rod master cylinder 4 respectively.

Below in conjunction with description of drawings principle of work of the present utility model:

When using the utility model, hydraulic power unit 7 advances the hydraulic oil pump in the fuel tank 6 rodless cavity of double acting single-piston rod master cylinder 4,2, the hydraulic oil of the single-piston rod of double acting simultaneously master cylinder 4,2 rod chambers acts on the rodless cavity of single-acting single-piston rod auxiliary oil cylinder 3,1, and 5 liang of table tops of hydraulic lifting machine are risen simultaneously; As connecting line generation booster of the present utility model, explosion relief valve F1, F2 will work immediately, stop hydraulic lifting machine 5 to descend; Because the double acting single-piston rod master cylinder 4,2 of the independent oil cylinder of two covers and 3,1 cross arrangement of single-acting single-piston rod auxiliary oil cylinder are in the both sides of hydraulic lifting machine 5 (as Fig. 1), even so the hydraulic oil leakage has taken place the independent oil cylinder of a cover in the course of the work, the phenomenon that single table surface descends or two table top descends simultaneously can not appear in hydraulic lifting machine 5 yet.And unidirectional self-lock unloading electromagnetic valve D1, D2, the D3 of employing ne-leakage, make the hydraulic oil can only nonreturn flow (during no power), simultaneously unloading electromagnetic valve D1, D2 are placed in double acting single-piston rod master cylinder 4,2 oil inlet positions (as Fig. 2), make two cover serial oil cylinders oil circuits relatively independent, guaranteed that any oil pipe explosion can not make hydraulic lifting machine 5 descend.So just reached without mechanical lock and also can guarantee purpose of safety.
