Abstract

The utility model relates to a hydraulic machine, particularly an electric hydraulic lifting jack, which comprises a chassis, a motor, an oil storage tank, a hydraulic pump and a hydraulic lifting jack, wherein the chassis has a folding type structure, the lower part of the chassis is provided with a moving wheel, the upper part of the chassis is successively provided with the hydraulic lifting jack, the hydraulic pump, the oil storage tank, the motor and an arm rest, an oil-in pipeline between the hydraulic pump and the hydraulic lifting jack is provided with a one-way valve, and an oil return pipeline between the oil storage tank and the hydraulic lifting jack is provided with a manual globe valve. During vehicle repair, the lifting jack can be directly pushed under a vehicle. The traditional manual oil supply is replaced by electric oil supply, and the extension quantity can reach to one meter. The utility model has the advantages of small ground occupation, convenient operation, low labor intensity, high work efficiency, high safety and long service life.

Description

The electric hydaulic jack
Technical field:
The utility model relates to hydraulic machinery, particularly a kind of electric hydaulic jack.
Background technology:
Hydraulic jack is a motor repair trade lifting instrument commonly used.This class instrument that uses mostly is the hand-hydraulic jack at present, relies on manual operation during use, promptly time-consuming effort again, and stroke is little, and load is restricted, poor safety performance, service life is short.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve defective and the deficiency that above-mentioned hand-hydraulic jack exists, and provide a kind of easy to use, save manpower, improve work efficiency, electric hydaulic jack that stroke is big.
The technical scheme that realizes the foregoing invention purpose is: this electric hydaulic jack comprises chassis, motor, petrol storage tank, Hydraulic Pump, hydraulic jack, this chassis is an accordion structure, be equipped with under it and move wheel, hydraulic jack, Hydraulic Pump, petrol storage tank, motor, handrail are housed on it successively, on the chargine line between this Hydraulic Pump and the hydraulic jack check valve is housed, on the oil return line between this petrol storage tank and the hydraulic jack manual shutoff valve is housed.
According to this electric hydaulic jack that this case provides, because complete engine set installation on removable folding chassis, therefore, can directly be pushed into it under car when carrying out automobile repair, floor area is little, has made things convenient for operation; This machine substitutes traditional manual fuel feeding by electronic fuel feeding, has not only reduced labour intensity, and has improved work efficiency; Its stroke of the hydraulic jack of this machine can reach one meter, and safety performance is improved, and it prolongs in event of overload not following service life greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
The described electric hydaulic jack of present embodiment is made of chassis 1, handrail 2, motor 3, petrol storage tank 4, manual shutoff valve 5, oil return line 6, Hydraulic Pump 7, check valve 8, chargine line 9, hydraulic jack 10, mobile wheel 11, this chassis 1 is an accordion structure, this is housed under it moves wheel 11, hydraulic jack 10, Hydraulic Pump 7, petrol storage tank 4, motor 3, handrail 2 are housed on it successively, on the chargine line 9 between this Hydraulic Pump 7 and the hydraulic jack 10 check valve 8 is housed, on the oil return line 6 between this petrol storage tank 4 and the hydraulic jack 10 manual shutoff valve 5 is housed.
During this machine of use, close manual shutoff valve 5, connect the power supply of motor 3, then by Hydraulic Pump 7 hydraulic oil in the petrol storage tank 4 is pumped into hydraulic jack 10, under the effect of high pressure oil, the piston jack-up jacked object of hydraulic jack 10 is shut down; When operation finishes, open manual shutoff valve 5, then high pressure oil flows back to petrol storage tank 4 by oil return line 6, and this moment, check valve 8 was closed.
