Abstract

The utility model discloses a movable electric jack, which comprises a motor, an oil tank, an oil pump and an electromagnetic directional valve in a movable vehicle, wherein the front end of the movable vehicle is hinged with an adjustable carrier, and a plunger hydraulic cylinder is mounted on the adjustable carrier. When in use, the utility model can be pushed to be under an object via the movable vehicle, user starts the motor and operates a directional switch to lift object and user is not demanded to be under the object, to improve safety, with high speed operation, improved working efficiency, reduced labor strength and eliminated accident. The utility model can lift object in narrow space, to expand application range, with wide application for vehicle maintenance.

Description

The mobile type electric jack

Technical field:

The utility model relates to a kind of instrument of lifting heavy thing that is used to push up, the technical field that belongs to lifting equipment, specifically a kind of mobile type electric jack, it is particularly suitable for that automobile is detected repairing, dismounting assembling, tire patching and changes working spaces such as tire and daily maintenance and use.

Background technology:

We know that jack also claims " erector ", and it is the big and little weight-lifting equipment of lift height of a kind of top weight lifting amount, and existing jack generally is divided into several structural shapes such as hydraulic pressure, spiral and tooth bar, are mostly to rely on manpower to drive and push up act work.Because characteristics such as jack has simple to operate, easy to use and top weight lifting amount is big have been widely used in various fields such as automobile repair, mechanical assembling, hydraulic and electric engineering and rescue and relief work.But, need not to dare not or would not speak up, existing jack also exists some defectives in actual use, it mainly shows as: need artificial back and forth carrying jack device when lifting object on the top, also needing the workman to climb to below top act object installs, the troublesome operation that heavy thing is lifted on dismounting jack and top, this is inefficiency not only, and it is careless slightly, also cause the accident that weighs wounded easily, exist great potential safety hazard, in the comparatively narrow occasion in individual operation space, because the workman can't install jack and push up the act operation, cause existing jack device to have bigger limitation in the use, in order further to expand effective range of use of jack, increase work efficiency, alleviate labor strength and thoroughly stop potential safety hazard, should improve this problem to be solved in the utility model just at the defective that existing jack exists.

The utility model content:

The purpose of this utility model is to propose a kind of mobile type electric jack in order to overcome the defective that existing jack in use exists, its technical scheme is achieved in that it mainly comprises moving body, oil pump, change-over valve, electrical motor and plunger-type cylinder, it is characterized in that: on moving body, be fitted with adjustable support, plunger-type cylinder is fixedly installed on the adjustable support, can easily moving body be pushed into when manipulating required top lift object below, the plunger-type cylinder that is fixedly installed on the adjustable support is lifted object over against pushing up, actuating motor drives oil pump work, press change-over swith by change-over valve to the plunger hydraulic oil supply cylinder, promoting plunger upwards rises slowly and the object top can be lifted to required operating altitude, when need return, press change-over swith again and make the change-over valve conversion direction, oil in object action of gravity lower plunger formula hydraulic actuating cylinder flows out and descends, and moving body is released to get final product again.

The utility model also has following technical characterictic:

Adjustable support is the car body front end that is fitted to moving body by the mode of being hinged, and can regulate the angle position of adjustable support easily, lifts adjustable support and can push moving body easily.

Between adjustable support and moving body, be provided with the location suspension member, can adjustable support stably be fixed on the moving body, make moving body transhipment displacement light and fast, manipulate very convenient by the location suspension member.

The utility model has following advantage in actual use:

1. can come and go to move to be transported to by moving body and lift the control position that weighs thing, can alleviate labor strength greatly by the top;

2. not needing the workman to climb to below top act object carries out installing/dismounting and pushes up the manual operations of lifting heavy thing, only moving body need be pushed into to be pushed up and lift below the object, Push switch can push up lifts heavy thing, easy for operation quick, can thoroughly eliminate safe hidden trouble, increase work efficiency;

3. as long as in can holding the narrow space scope of moving body, can both push up the operation of lifting heavy thing, the range of use of having widened greatly.

4. the utility model is simple in structure, easy to manufacture, long service life, and wide accommodation is particularly suitable for keeping in repair the bigger automobile maintenance enterprise of portfolio and uses.

Description of drawings:

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

Fig. 2 is a hydraulic schematic diagram of the present utility model.

The specific embodiment:

The embodiment of the mobile type electric jack that the utility model proposes is as follows: it is mainly by the electrical motor 3 that is installed on moving body 4, fuel tank 8, gear type pump 11, oil pipe 9, solenoid directional control valve 10, adjustable support 2 and plunger-type cylinder 1 constitute, adjustable support 2 is connected in the car body front end of moving body 4 by the mode of being hinged, plunger-type cylinder 1 is fixedly installed on the adjustable support 2, on the handrail 6 of moving body 4, be equipped with change-over swith 7, at the bottom of the car of moving body 4, be fitted with roller 5, need push up and lift when weighing the thing operation, by location suspension member 12 adjustable support 2 is upwards lifted and can easily moving body 4 to be pushed into by below the top act object, put down adjustable support 2, plunger-type cylinder 1 is lifted object over against pushing up, actuating motor 3 driven gear pumps 11, press change-over swith 7 and make electromagnet 15 energisings, by gear type pump 11 through solenoid directional control valve 10 to plunger-type cylinder 1 fuel feeding, make

plunger

14,13 upwards rise the act of object top successively to required operating altitude, when needs return, press change-over swith 7 again and make electromagnet 16 energisings, make solenoid directional control valve 10 conversion directions, by gravity plunger 13,14 returns that slowly descend, in the defeated oil sump tank 8 of the fluid in the plunger-type cylinder 1, adjustable support 2 is upwards lifted again and fixed by location suspension member 12, releasing moving body 4 is complete operation.
