Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As described in Figure 1, the lowering or hoisting gear with hydraulic booster, including support meanss, the support meanss include hollow branch
Dagger 11, elevating screw 2 is installed on the support column 11, is provided with the support column 11 of the lower section of elevating screw 2
Supporting plate 12, hydraulic servo, the hydraulic booster are installed between the bottom of the elevating screw 2 and the support meanss
Device is arranged between the elevating screw 2 and the supporting plate 12, and the hydraulic servo includes power-assisted oil cylinder 31, described
The plunger end of power-assisted oil cylinder 31 is fixedly connected with the supporting plate 12, cylinder body of the power-assisted oil cylinder 31 away from plunger end with it is described
Elevating screw 2 is fixedly connected, and the power-assisted oil cylinder 31 is connected with hydraulic station 32, the power-assisted oil cylinder 31 and the liquid by oil circuit
Overflow valve 33 is installed on oil circuit between pressure station 32, the elevating screw 2 is connected with lifting drive, the lifting
Drive device includes motor (not shown), and the clutch end of the motor is connected with worm screw 41, institute
State worm screw 41 and be connected with screw 42, the elevating screw 2 is through the screw 42 and is threadedly coupled.
Lowering or hoisting gear operation principle with power-assisted oil cylinder：
The technical program is mounted with the basis of conventional lowering or hoisting gear for reducing elevating screw 2 to the pressure of screw 42
Power-assisted oil cylinder 31, power-assisted oil cylinder 31 can effectively extend the life-span of lifting drive.
The cylinder body of power-assisted oil cylinder 31 is connected with elevating screw 2, and piston-rod lower end is withstood in a fixed supporting plate 12.Support
Plate 12 and support column 11 link together, and the housing of support column 11 and lifting drive links together.
The pressure of whole hydraulic system is first set on overflow valve 33 according to the weight that lowering or hoisting gear to be lifted.Starting
Before lowering or hoisting gear, first start the fuel feeding of hydraulic station 32, when the pressure in power-assisted oil cylinder 31, which reaches, sets pressure, lowering or hoisting gear driving
Motor can just start.
For lowering or hoisting gear during raising and lowering, power-assisted oil cylinder 31 keeps constant pressure duty (if instantaneous pressure
Too high, overflow valve 33 can automatically release unnecessary pressure oil), cylinder piston rod is withstood in supporting plate 12, in reaction force
Under effect, to one upward power of cylinder body of power-assisted oil cylinder 31, power passes to elevating screw 2, to offset elevating screw 2 and screw
Active force before 42, and then reduce worm screw 41, screw 42, the bearing capacity of elevating screw 2, extend lowering or hoisting gear uses the longevity
