Abstract
The invention relates to a power-driven hydraulic jack. The power-driven hydraulic jack comprises a base plate, a hydraulic oil cylinder, a motor, a hydraulic oil tank, a hydraulic gear pump, a flange, a distributor, a motor hydraulic solenoid valve and a hydraulic oil pipe. The power-driven hydraulic jack is mainly used for replacing manual operation when a vehicle is maintained; an operator can jack the vehicle from a great distance; the advantages of being safe, compact in structure, convenient to move and simple in operation and saving labor are achieved; and the power-driven hydraulic jack is more even and stable in lifting speed compared with a pneumatic jack and manual operation during work.
Description
Technical field
The present invention relates to a kind of jack, particularly relate to a kind of electric hydraulic lifting jack.
Background technology
Jack is that part is lifted as equipment in one rigidity top, by the light little weight-lifting equipment of top bracket jacking weight in stroke, is a kind of conventional tool often used when automobile, truck maintenance.There is the product that two kinds of the same type in the market: 1. hand jack 2. Pneumatic jack.Hand jack carrys out jack-up with M/C to rise thing, and operative employee must near hoisting thing, and such danger is higher.Pneumatic jack needs air compressor to connect jack, uses inconvenience, and air pressure requires high, and lifting velocity is unstable, and air pump and jack junction leakage of oil especially severe, enters winter and also will change hydraulic oil.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric hydraulic lifting jack, and this electric hydraulic lifting jack can make lifting heavy goods convenient, and lifting velocity is stablized.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of electric hydraulic lifting jack, this electric hydraulic lifting jack comprises base plate, hydraulic ram, electrical motor, hydraulic reservoir, hydraulic gear pump, flange, distributing box, electrical motor hydraulic buttery valve and hydraulic oil pipe, it is characterized in that: described electrical motor is fixedly mounted on base plate, hydraulic reservoir is arranged on the left side of electrical motor, the bottom of hydraulic reservoir is arranged on base plate, and the both sides of base plate are provided with hydraulic ram;
The mouth of described electrical motor has hydraulic gear pump by Flange joint, and the upper end of hydraulic gear pump is connected with distributing box, distributing box is provided with hydraulic oil pipe interface, and the right side of distributing box is provided with an electrical motor hydraulic buttery valve;
One end of described hydraulic oil pipe connects on the dispenser, and the other end of hydraulic oil pipe is connected to two oil-collecting holes up and down of hydraulic ram.
Described electrical motor hydraulic buttery valve adopts three position four-way electromagnetic valve;
There is protrusion otic placode the bottom of described hydraulic ram case, this otic placode has waist type groove, adopts assembling bolt to be connected between otic placode with base plate.
The invention has the advantages that: motor-driven jack of the present invention, mainly during maintenance vehicle, manual operations can be replaced, operator can jack-up vehicle at a distance, there is safety labor-saving, compact conformation, conveniently moving, advantage simple to operate, more uniform and stable than pneumatic and manual lifting velocity during motor-driven jack work.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the constructional drawing of electric hydraulic lifting jack.
As shown in Figure 1: 1, base plate; 2, hydraulic ram; 3, electrical motor; 4, hydraulic reservoir; 5, hydraulic gear pump; 6, flange; 7, distributing box; 8, electrical motor hydraulic buttery valve; 9, hydraulic oil pipe; 10, otic placode; 11, assembling bolt.
Detailed description of the invention
The following examples can make the present invention of professional and technical personnel's comprehend, but therefore do not limit the present invention among described scope of embodiments.
A kind of electric hydraulic lifting jack as shown in Figure 1, this electric hydraulic lifting jack comprises base plate 1, hydraulic ram 2, electrical motor 3, hydraulic reservoir 4, hydraulic gear pump 5, flange 6, distributing box 7, electrical motor hydraulic buttery valve 8 and hydraulic oil pipe 9, it is characterized in that: described electrical motor 3 is fixedly mounted on base plate 1, hydraulic reservoir 4 is arranged on the left side of electrical motor 3, the bottom of hydraulic reservoir 4 is arranged on base plate 1, and the both sides of base plate 1 are provided with hydraulic ram 2;
The mouth of described electrical motor 3 is connected with hydraulic gear pump 5 by flange 6, and the upper end of hydraulic gear pump 5 is connected with distributing box 7, distributing box 7 is provided with hydraulic oil pipe interface, and the right side of distributing box 7 is provided with an electrical motor hydraulic buttery valve 8;
One end of described hydraulic oil pipe 9 is connected on distributing box 7, and the other end of hydraulic oil pipe 9 is connected to two oil-collecting holes up and down of hydraulic ram 2.
Described electrical motor hydraulic buttery valve 8 adopts three position four-way electromagnetic valve;
The bottom of described hydraulic reservoir 4 has protrudes otic placode 10, this otic placode 10 has waist type groove, adopts assembling bolt 11 to be connected between otic placode 10 with base plate 1.
The principle of work of electric hydraulic lifting jack of the present invention is: hydraulic ram 2 has two, the lifting while that two hydraulic rams 2 being taken blame for others, and two hydraulic rams 2 are separately positioned on the two ends of base plate 1, this base plate is wider longer, lifting is quick, the flow velocity that the electrical motor hydraulic buttery valve 8 be connected with electrical motor 3 in addition controls liquid makes electric hydraulic lifting jack lifting speed more at the uniform velocity, three position four-way electromagnetic valve controls all can not slide voluntarily when generation power failure or hydraulic pipe fracture are popped, necessary actuating motor 3, hydraulic gear pump 5 is driven to start pump oil, electrical motor hydraulic buttery valve 8 is opened, hydraulic ram just can one save and slides, fully ensure that the safety of use.
The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
