Abstract

The invention discloses a lifting mechanism of a lifter and belongs to the technical field of lifter devices. The lifting mechanism comprises a supporting arm, an installing seat fixedly connected with the supporting arm, a lifting tray device and a lifting device. The lifting tray device comprises trays and lifting pads fixed to the trays, wherein N rubber nails are evenly arranged on the lifting pads. The lifting device comprises a sleeve arranged right above the installing seat, wherein a loop bar movably connected with the sleeve is arranged in the sleeve. The lifting mechanism further comprises a spring fixedly connected with the installing seat and the tray respectively, wherein the other end of the loop bar is fixedly connected with the tray. The lifting mechanism can reduce the load of the lifting tray with large stress, stress balance of the four lifting trays is achieved, flexible lifting of the lifting trays and an automobile chassis is achieved, and damage caused by the fact that the automobile chassis is subjected to the large stress for a long period of time is reduced. In addition, friction force between the lifting mechanism and a part of the automobile chassis is increased, accordingly lifting and slipping phenomena do not occur, and the lifting safety is improved.

Description

A kind of lifting machine lift mechanism

Technical field

The invention belongs to lifting machine equipment technical field, more particularly, relate to a kind of lifting machine lift mechanism.

Background technology

Lifting machine is a kind of equipment being applied to automobile inspection, can by vehicle lifting, vehicle bottom is overhauled, the hold-down arm of lifting machine supports vehicle, hold-down arm is driven to be elevated by actuating unit again, carried out the lifting of vehicle, and hold-down arm is the lift mechanism on hold-down arm to the strong point that vehicle supports.

Current lift mechanism is only that a mount pad and one lift dish, lifts dish and contacts with vehicle bottom.Because lift dish when lifting automobile, on lifting machine, the dish of lifting at four angles place can because different in the position of bottom of car lifting, thus corresponding height is also different, but it is all rigid lifting substantially that lifting machine of the prior art lifts dish, cause and different lift varying in size of the power that dish bears, thus accelerate the damage of lifting dish, the part replacement cycle is short, maintenance cost is high, and dismounting bothers; Car chassis also can be stressed excessive because of part, is also if things go on like this kind of damage that can not be ignored to car chassis.The part replacement cycle is short, and maintenance cost is high, and dismounting bothers.

Summary of the invention

the problem that 1, will solve

For the above-mentioned problems in the prior art, the invention provides a kind of lifting machine lift mechanism, the load of stressed larger lift tray can be reduced, thus realize four lift tray stress equalizations, thus solve four angles place on lifting machine lift dish because different in the position of bottom of car lifting, corresponding height is different and cause different varying in size of the power that dish bears of lifting, and the phenomenon of accelerating to lift the damage of dish occurs, thus the replacement cycle of elongate member, reduce maintenance cost.

2, technical scheme

In order to solve the problem, the technical solution adopted in the present invention is as follows:

A kind of lifting machine lift mechanism, comprise hold-down arm, the mount pad be fixedly connected with described hold-down arm, lift and coil device and lifting device, described dish device of lifting comprises pallet and is fixed on described pallet lifts pad, described in lift that pad is upper evenly distributedly has N number of rubber tack, described N is integer; Described lifting device comprises the sleeve pipe be located at directly over described mount pad, is provided with the loop bar be flexibly connected with it in described sleeve pipe, also comprises the spring be all fixedly connected with described mount pad and pallet respectively, and the described loop bar other end is fixedly connected with described pallet.

Further, described sleeve pipe and loop bar are all located at the inside of described spring.

Further, lift pad and be made up of rubber, and the concentric circles identical with sized by described pallet described in.

3, beneficial effect

Compared to prior art, beneficial effect of the present invention is:

(1) the present invention can reduce the load of stressed larger lift tray by the lifting device arranged, thus realize four lift tray stress equalizations, thus solve four angles place on lifting machine lift dish because different in the position of bottom of car lifting, corresponding height is different and cause different varying in size of the power that dish bears of lifting, and the phenomenon of accelerating to lift the damage of dish occurs, thus the replacement cycle of elongate member, reduce maintenance cost;

(2) the present invention lifts dish device by what arrange, thus realizes lifting dish and lift with the flexibility of car chassis, reduces car chassis because of the stressed comparatively large and damage that produces for a long time; And increase and the friction force of car chassis part carried, thus there will not be and lift skidding, improve the safety of lifting.

(3) the present invention also has the advantage that structure is simple, reasonable in design, be easy to manufacture.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described further.

As shown in Figure 1, a kind of lifting machine lift mechanism, comprise hold-down arm 1, the mount pad 8 be fixedly connected with described hold-down arm 1, lift and coil device and lifting device, described dish device of lifting comprises pallet 4 and is fixed on described pallet 4 lifts pad 2, described lifting evenly distributedly on pad 2 has N number of rubber tack 3, and described N is integer; Described lifting device comprises the sleeve pipe 7 be located at directly over described mount pad 8, the loop bar 6 be flexibly connected with it is provided with in described sleeve pipe 7, also comprise the spring 5 be all fixedly connected with described mount pad 8 and pallet 4 respectively, described loop bar 6 other end is fixedly connected with described pallet 4.The load of stressed larger lift tray can be reduced by the lifting device arranged, thus realize four lift tray stress equalizations, thus solve four angles place on lifting machine lift dish because different in the position of bottom of car lifting, corresponding height is different and cause different varying in size of the power that dish bears of lifting, and the phenomenon of accelerating to lift the damage of dish occurs, thus the replacement cycle of elongate member, reduce maintenance cost; Lift dish device by what arrange, thus realize lifting dish and lift with the flexibility of car chassis, reduce car chassis because of the stressed comparatively large and damage that produces for a long time.

In addition, described sleeve pipe 7 and loop bar 6 are all located at the inside of described spring 5.Described pad 2 of lifting is made up of rubber, and the concentric circles identical with sized by described pallet 4.

During lifting, because the system height of car chassis is different, thus there will be the phenomenon of the stressed size inequality of lift tray, stressed larger lift tray meeting Compress Spring 5, the meanwhile stressed increase of the lift tray device in other corners, thus the pressure reducing this stressed larger lift tray device, and increase the friction force with the car chassis part carried by lift pad 2 and the rubber tack 3 arranged, thus there will not be and lift skidding, improve the safety of lifting.

Schematically above be described the present invention and embodiment thereof, this description does not have restricted, and also just one of the embodiments of the present invention shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the invention aim, designing the frame mode similar to this technical scheme and embodiment without creationary, all should protection scope of the present invention be belonged to.
