Abstract

The utility model provides a movable electrical jack for vehicles which is a device which can lift the repaired automobiles or machine tools to be conveniently repaired. The movable electrical jack for vehicles comprises a motor, a worm, a worm gear case, a screw, a wheel, etc. The repairing way of the building ground hole or lying under the vehicles is altered. The utility model has the advantages of high safety, simple structure and low cost, and is a useful tool in maintain service plants (stations) and other lifting operations.

Description

Movable electrical jack for vehicles

The utility model proposes a kind of device that makes things convenient for vehicle maintenance and repair---can move spiral motorcar electric and lift high device.

At present, also do not find this type of device as yet, automobile can be lifted height, the vehicle maintenance and repair personnel can keep in repair under by the auto repair abdomen easily, generally all are building melt pits, are sailed on the melt pit by auto repair, and the maintainer squats and has a car overhauled in the hole.

The purpose of this utility model is to propose a kind ofly can easily this device be moved to the device that is lifted under the auto repair, carries out maintenance operation for the maintainer.

Technical solution of the present utility model: structure as shown in drawings.It mainly contains and is contained in that wheel 1 supports on four jiaos of the frames, between two transmission worm cases, be provided with electric control box 2 and electrical motor 3, two transmission worm screws 4, two spirals 5 are located at worm case inboard and top respectively, frame two ends are equipped with worm case 6 respectively, have bearing 7, worm case center that worm gear 8 is arranged on the worm case inner bottom surface, it is bearing on the bearing, nut 11 is connected with worm gear, and big screw rod 9, small screw 10 are all in worm case stamen portion, vertical layout.Its working process is such, and electrical motor 3 is as power, by 4 rotations of pulley drive worm screw, the worm gears that drive in two worm cases 6 rotate synchronously, and two screw pairs are arranged in the worm gear, when needs with being added to three screw pairs, can make that spiral 5 stretches out, indentation, reach the purpose of lifting high landing.When work, dolly can move to the operation point with wheel 1 hand push, and this takes turns spring also is housed, and can be compressed into sleeve by hoisting force, and lifting weight is so directly passed on ground by frame, avoids wheel to damage.Whole mechanical device makes electrical motors to forward and backward and restriction with knob operation electric control box 2.After worm screw is by electric motor drive, worm gear 8 promptly rotates, nut 11 is equipped with on its top, the big screw rod 9 of assembling in this nut is equipped with little one small screw 10 that encloses, when starting working again in big screw rod, because small screw 10 friction force are less than big screw rod 9, so it rises action earlier, after waiting to be raised to the position, and then big screw rod 9 just continues to rise moving.It is that two screw rods are exsertile apart from sum that whole process is lifted high height.When returning landing, otherwise by this process.When having a power failure, also available worm screw afterbody jack is manually lifted.

This lifts high device can be high 1.2 meters with automobile (or facility) act, can change custom building melt pit and maintainer and lie on the back, be drilled in the mode that repairs under the car abdomen.Safe and reliable, simple in structure, cheap.

Accompanying drawing 1 is a structure front elevation of the present utility model.

Accompanying drawing 2 is structure cutaway views of the present utility model.

In the accompanying drawing 1 is wheel, the 2nd, electric control box, the 3rd, electrical motor, the 4th, transmission worm screw, the 5th, spiral, the 6th, worm case, the 7th, bearing, the 8th, worm gear, the 9th, big screw rod, the 10th, small screw, the 11st, nut.

Claims

1, can move spiral motorcar electric and lift high device, it is characterized in that having the wheel 1 on four jiaos of frames of being contained in to support, between two transmission worm cases, be provided with electric control box 2 and electrical motor 3, be respectively equipped with two transmission worm screws 4 and two spirals 5 in worm case inboard and top, frame two ends are equipped with worm case 6 respectively, and bearing 7 arranged on the worm case inner bottom surface, there is worm gear 8 at the worm case center, it is bearing on the bearing, nut 11 is connected with worm gear, and large and small screw rod 9,10 is located at worm case stamen portion vertical unit.
