Abstract

The utility model relates to a lifting machine, in particular to an opening four-column lifting machine which overcomes the drawbacks that the common four-column lifting machine is inconvenient for entering and leaving while in maintenance which results in difficulties for maintenance work, comprising a main upright column, a vice upright column, a car-bearing running plate and a beam, wherein one end of the car-bearing running plate is supported by the beam and the other end is supported by a cantilever beam, that is an opening is arranged on the beam between the main upright column and the adjacent vice upright column. The utility model has the advantages of simple structure, low cost, convenient entering and leaving while in maintenance, good rigidity, intensity and stability of the overall lifting machine.

Description

Open type four post lifting machines

Technical field

The utility model relates to a kind of lifting machine, specifically a kind of open type four post lifting machines.

Background technology

In the maintenance industry of automobile, car chassis, brake are keeped in repair and during changing of tire, service personnel often need be faced upward to lie on the ground, automobile below and carry out operation, perhaps automobile is left to the trench place, the operating personnel carries out operation in trench, very inconvenience.And along with the increase of automobile quantity, the parking stall is more and more nervous, solves the problem of parking difficulty, becomes to demand the difficult problem that will solve urgently.At present, occurred many lifting equipment both at home and abroad, wherein comparatively desirable lifting equipment is the lifting machine, and it is simple in structure, and cost is low, good stability in the use.

Four-column type lifting machine commonly used as shown in Figure 1, whole lifting machine by a head tree 1, three secondary columns 2, crossbeam 3, slide units 4, hold that car runs plate 5 and power unit 6 is formed, wherein power unit 6 is arranged on the head tree 1.Crossbeam 4 is set respectively between column, and by power unit 2, crossbeam 4 can be done along the slide unit in the column 4 and move up and down.Because whole device is symmetrical structure, so its stability better.When but the lifting machine that utilizes this kind structure keeped in repair, the maintainer passed in and out this device inconvenience very, therefore maintenance work had been caused certain difficulty.

Summary of the invention

The purpose of this utility model is to overcome the defective of existing four post lifting machine inconvenient maintenance, a kind of open type four post lifting machines have been proposed, it not only has the advantage of general lifting machine, promptly simple in structure, cost is low, and turnover is convenient when using the lifting machine of this kind structure, be convenient to the carrying out of maintenance work, have rigidity and intensity preferably, stability better.

The utility model is realized by the following technical solutions: a kind of open type four post lifting machines, comprise head tree, secondary column, hold car race plate, crossbeam and cantilever beam, an end that wherein holds car race plate is supported by crossbeam, the other end is supported by cantilever beam, promptly on the crossbeam between head tree and the adjacent secondary column opening is set.

In the utility model, between other two secondary columns crossbeam is set, the cross-sectional area that the column of cantilever beam wherein is set is greater than the cross-sectional area of the column that crossbeam is set.

The beneficial effects of the utility model are: by on the crossbeam opening being set therein, promptly on head tree and adjacent secondary column, cantilever beam is set respectively, make the maintainer when carrying out maintenance work, can pass in and out this device easily, be convenient to the carrying out of maintenance work.But cantilever beam is set also has certain defective, at first cantilever beam can bear bigger pressure in use, can produce certain moment of torsion by column simultaneously, therefore can reduce the stability of whole lifting machine, and its rigidity and intensity are affected, and by increase the cross-sectional area of the column of cantilever beam is set, overcome the moment of torsion that column produces, and the strength and stiffness of lifting machine can be affected, have stability preferably.

The specific embodiment

As shown in Figure 2, whole lifting machine by head tree 1,

secondary column

6,8 and 9, power unit 2, cantilever beam 4, crossbeam 5, hold car and run plate 3 and form.Power unit 2 is arranged on the head tree 1, on the crossbeam between head tree 1 and the secondary column 6 opening is set, and promptly on head tree 1 and secondary column 6 cantilever beam 4 is set respectively, so that the turnover of service worker.Between

secondary column

8 and 9, crossbeam 5 is set.Wherein cantilever beam 4 and crossbeam 5 all can move up and down along the slide plate in the column 7 by the driving of power unit 2, promote to hold car race plate 3 to suitable position.In four columns, the cross-sectional area of head tree 2 and secondary column 6 is provided with the rigidity and the intensity that have guaranteed whole lifting machine by this and is not affected because of cantilever beam 4 is set greater than the cross-sectional area of

secondary column

8 and 9.

The utility model has the advantages that: turnover conveniently is convenient to the carrying out of maintenance work when carrying out maintenance work, has overcome the moment of torsion that generation is set because of cantilever beam simultaneously, has guaranteed the strength and stiffness of whole lifting machine, and stability better.
