The hydraulic conversion type lifting device has the advantages of time saving and labor saving.
Description
Technical field:
The present invention relates to hydraulic gear, particularly a kind of being applicable to raising compared with heavy object or mobile hydraulic pressure change type hoisting device.
Background technology:
Current hydraulic lift, be pressure by a hydraulic actuating cylinder by hydraulic pressure transfer to piston, move or lifting heavy through piston rod.The problem that this hydraulic gear exists is, because the piston barrel diameter of hydraulic actuating cylinder and area are certain, it is also constant when work, being added in the pressure on hydraulic pressure in hydraulic actuating cylinder, so piston ultimate range of transmission in hydraulic actuating cylinder is certain, weight can not be passed to higher or farther position.The object of constant weight row to be moved on to higher or farther position, must strengthen the diameter of hydraulic reservoir and corresponding increase piston.Change fuel tank and diameter of piston and both took a lot of work, require great effort, increase again economic input cost.
Summary of the invention:
The object of this invention is to provide a kind of saving of labor, laborsaving, the hydraulic pressure change type hoisting device that input cost is low.
Technical solution of the present invention completes as follows, it comprises a lifting hydraulic cylinder, it is characterized in that: in a side of lifting hydraulic cylinder, a hydraulic fluid tank is installed, in hydraulic fluid tank, be horizontally installed with a Hydraulic Pump, Hydraulic Pump two bottom sides is provided with respectively a stay bearing plate downwards, liquid nowel the latter half is divided into left and right two parts by two stay bearing plates, in hydraulic fluid tank, centered by Hydraulic Pump, be horizontally installed with a pressure converter, the flush fit that slides respectively in pressure converter two-port has a sliding cap, left sliding cap is connected on the connecting rod of hydraulic pump piston, right sliding cap is connected on a telescopic pipe being communicated with hydraulic actuating cylinder, in Hydraulic Pump bottom centre to having a check valve, on check valve, be outwards provided with inlet, the telescopic pipe of Hydraulic Pump right-hand member and right sliding cap junction are provided with check valve, between hydraulic fluid tank top and the piston tube of hydraulic actuating cylinder, be connected with a hydraulic hose, a load-carrying piston head is upwards installed in the piston tube of hydraulic actuating cylinder, be provided with a blowdown valve at a side lower part of hydraulic actuating cylinder, on the left sliding cap of pressure converter, be extended with to the left a connecting rod, connecting rod outer end is provided with a crank, crank two ends are rotatably connected on the outstanding casing in hydraulic fluid tank left side, be provided with a handle in one end of crank, on pressure converter, be respectively equipped with a spacing stop near the cap outside that horizontally slips, in the piston tube of Hydraulic Pump, be provided with an equalizing pipe being communicated with hydraulic fluid tank.
The present invention compared with prior art has advantages of that lifting weight is laborsaving, saves time, cost is low.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Describe embodiment in detail in conjunction with above accompanying drawing.The present invention is that a side at a lifting hydraulic cylinder 13 is through being provided with a hydraulic fluid tank 1 communicating pipe 11, in hydraulic fluid tank, be horizontally installed with a Hydraulic Pump 20, the two bottom sides of Hydraulic Pump is provided with a pair of stay bearing plate 8 downwards, hydraulic fluid tank the latter half is divided into left and right two parts by stay bearing plate, in hydraulic fluid tank, centered by Hydraulic Pump, be horizontally installed with a pressure converter 18, in pressure converter two-port, sealing is sliding combined with a sliding cap 5 respectively, left sliding cap is connected on the connecting rod of hydraulic pump piston 7, right sliding cap is arranged on a telescopic pipe being communicated with hydraulic actuating cylinder 10, in Hydraulic Pump bottom centre to having a check valve 19, on check valve, be outwards provided with inlet 9, the telescopic pipe of Hydraulic Pump right-hand member and right sliding cap junction are provided with a check valve 17, between the cavity of the piston tube 14 of hydraulic fluid tank top and hydraulic actuating cylinder, be connected with a telescopic hydraulic hose 16, a load-carrying piston head 15 is upwards installed in hydraulic cylinder piston pipe, for lifting weight.Be provided with a blowdown valve 12 at a side lower part of hydraulic actuating cylinder, on the left sliding cap of pressure converter, be extended with to the left a connecting rod 4, connecting rod outer end is provided with a crank 3, crank two ends are rotatably connected on the outstanding casing in hydraulic fluid tank left side, be provided with a handle 2 in the upper end of crank, the right sliding cap outside that keeps left on pressure converter is respectively equipped with a spacing stop 6, is provided with an equalizing pipe being communicated with hydraulic fluid tank 21 in the piston tube of Hydraulic Pump.
Principle of work of the present invention is, while being moved to the left with external force turning handle, drive the sliding cap of Hydraulic Pump to be moved to the left together with piston by crank and connecting rod, liquid non-return valve in pressure converter is closed, the feed liquor one-way valve opens of Hydraulic Pump bottom simultaneously, in draws fluid Hydraulic Pump, in the time that left sliding cap moves to left limit stop, equalizing pipe is communicated with hydraulic fluid tank automatically, feed liquor check valve 19 is closed, then turning handle moves right, pass through crank, connecting rod drives the sliding cap on pressure converter to move right together with piston, pressure in Hydraulic Pump is outputed in hydraulic actuating cylinder through telescopic pipe check valve 17, hydraulic cylinder piston is raise together with load-carrying piston head.In the time that turning handle moves right, the telescopic pipe closed check valve in pressure converter on sliding cap, keeps the hydraulic pressure of hydraulic actuating cylinder to make piston and load-carrying piston head constantly be elevated to certain altitude.If the area of hydraulic pump pressure converter piston equates with the area of hydraulic cylinder piston, so each turning handle makes both miles of relative movement also identical with rise height.
