Abstract

The utility model relates to a hydraulic vehicle lift with a rotary disk for vehicles. The upper end of a hydraulic jack tray is provided with the rotary disk; a plane thrust bearing is arranged between the lower plane of the rotary disk and the upper plane of the tray. The rotary disk is sheathed on the central shaft of the tray via a central hole. The utility model has two executive plans: manual rotation and power-driven rotation. A power-driven rotary disk is provided with a gear ring actuated by a pinion driven by a motor and a decelerating machine. The utility model can lift a whole vehicle in the mechanical drive way, and work for turning around, pulling away from a mud puddle, replacing tires, etc. The hydraulic vehicle lift has the advantages of multiple functions, mobility, labor saving, convenient operation, small size, portability on vehicles, etc.

Description

The hydraulic pressure vehicle lift of rotating disc is housed

The utility model relates to holds up the turner tool, a kind of specifically hydraulic pressure vehicle lift that rotating disc is housed.

Hold up the turner tool for example oil jack be the indispensable car repair tool of automobile, it is little that it has a volume, can carry with car, advantage easy to use, present hydraulic jack is generally manually, and its function is automobile one side jack-up can be convenient to carry out such as changeing operations such as tire, this mixed jack exists function few, the time-consuming shortcoming of manually requiring great effort.

The purpose of this utility model provides a kind of hydraulic pressure vehicle lift that rotating disc is arranged, and it is provided with tracker action, vehicle complete vehicle can be held up and vehicle body is rotated, and conveniently carries out operations such as somerset, repairing.

The purpose of this utility model is to realize like this

A kind of hydraulic pressure vehicle lift that rotating disc is housed, its structure comprises hydraulic jack, base is fixed in the hydraulic actuating cylinder lower end of jack, its piston rod upper end is fixedly connected with pallet, it is characterized in that: rotating disc is housed in the pallet upper end, between the plane plain thrust bearing is housed on this rotating disc lower plane and the pallet, this rotating disc centre hole is set in the pallet center shaft, between its fitting surface radial bearing is housed.

In one embodiment, the described plane roller bearing that is installed between rotating disc and the pallet is to be contained on the annular groove of rotating disc lower plane and the pallet by some steel balls to constitute in the corresponding annular groove in plane, this annular groove is an angle of 90 degrees, described steel ball contacts with the square edge of following annular groove, this annular groove degree of depth is suitable, and making on rotating disc lower plane and the pallet has certain interval between the plane.

In preferred embodiment, on the described rotating disc gear ring is arranged, this gear ring is driven by miniature gears, this miniature gears is by motor---the reductor transmission, this motor---reductor is packed in the lower plane of pallet, and this motor is powered by automobile power source through plug, and this motor is handled by hand switch.

In preferred embodiment, described motor---reductor is connected with oil pump, and this oil pump connects hydraulic jack with flexible pipe, forms oil supply loop, and this oil pump is handled by hand switch.

The utlity model has following actively useful effect:

1. rotating disc is placed in the appropriate location under the vehicle body, vehicle complete vehicle can be held up;

2. can carry out somerset, when the garage relaxation needs tune on limited road, use this vehicle lift that roof is played the Rotate 180 degree, it is convenient especially to reverse end for end;

3. behind the rain, when automobile falls in mud, do not need to look for three or five people to push away, more do not need to look for other self-propelled vehicle traction, as long as with vehicle lift car is propped up, car load rotates to suitable position, just can easily car be driven away.

4. when motor tire needs out of joint are changed,, no longer need car is propped up, deducted the chaufeur worries of earth from head to foot with the manual control jack for the hydraulic pressure vehicle lift that tracker action is housed.

5. being particularly suitable for lilliput cars such as car, micro-bus, small tools car uses.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the external form scheme drawing of a kind of embodiment of the utility model, is oblique drawing, does not have motor-driven device.

Fig. 2 is the front elevation of Fig. 1, and local parting shows its structure.

Fig. 3 is the profile scheme drawing of another embodiment of the utility model, and tracker action is arranged.

Fig. 4 is the local parting front elevation of Fig. 3.

Fig. 5 is the scheme drawing that the utility model is applied to somerset.

Fig. 6 is the scheme drawing that the utility model is applied to automobile repair.

The hydraulic pressure vehicle lift that rotating disc is housed of the present utility model, its structure comprises that hydraulic jack please refer to Fig. 1, Fig. 2, base 2 is fixed in hydraulic actuating cylinder 1 lower end of jack, its piston rod 3 upper ends are fixedly connected with pallet 4, in the pallet upper end rotating disc 5 are housed, and between the plane plain thrust bearing are housed on this rotating disc lower plane and the pallet, this rotating disc centre hole is set in pallet center shaft 7, and radial bearing 8 is housed between its fitting surface.

In one embodiment, the described plane roller bearing that is installed between rotating disc and the pallet is to be contained on the annular groove of rotating disc lower plane and the pallet by some steel balls 6 to constitute in the corresponding annular groove in plane, this annular groove is an angle of 90 degrees, described steel ball contacts with the square edge of upper and lower annular groove, this annular groove degree of depth is suitable, and making on rotating disc lower plane and the pallet has certain interval between the plane.

The utility model has type hand and two kinds of embodiments of motor driven type:

Fig. 1 Fig. 2 is type hand embodiment, and hoisting of hydraulic jack driven by hand lever, and it is configured to prior art, when body mount rotates on rotating disc, promotes the vehicle body rotation by manpower.

Fig. 3 Fig. 4 is motor driven type embodiment, on the described rotating disc 5 gear ring 9 is arranged, this gear ring is driven by miniature gears 10, this miniature gears is by motor---reductor 11 transmissions, this motor---reductor is packed in the case of lower plane of pallet, this motor is powered by automobile power source through plug, and this motor is handled by hand switch.

During enforcement, described plain thrust bearing can use standard flat thrust ball bearing or plane axial roller bearing.

During enforcement, described radial bearing can use radial ball bearing shown in the accompanying drawing, also can use the plain bearing of copper material or nylon material.

During enforcement, in tracker action embodiment was arranged, the described gear ring that is loaded on the rotating disc can use involute straight-tooth gear ring shown in the drawings, also can use the finishing bevel gear cuter gear ring, this finishing bevel gear cuter gear ring is contained on the rotating disc lower plane, by motor---and the conelet tooth of reductor transmission drives.

Fig. 5 Fig. 6 shows that the utility model uses scheme drawing, and Fig. 5 shows somerset, props up place under repair but Fig. 6 shows automobile.
