Description

Lifting machine without lever

The utility model is a kind of lifting equipment that is applied to the job space that the cross-check sum of car, utility van and light-duty truck repairs.

At present motor repair trade generally also adopts the repairman to lie in place under repair on the ground of automobile lower, operation form also has living space, but all be the aerial device that pillar (two pillars, four-column type) arranged basically, this equipment occupies the area in certain workshop, and also inconvenience of levelling operation height and repair work operation.In the Chinese patent also report have " parallel four connecting rod automobiles hoist machine " to reach the application of " automobile elevator " two utility model patents, but its constructional feature and the utility model are completely different, so all have different at usage condition with the complete machine aspect of performance.

The purpose of this utility model is to cut and cut down the stent-type roman appearance structure of assembly in a kind of employing of design, is power with hydraulic pressure, is provided with the no post lift of automatic self-locking and release mechanism.

The utility model is realized with following scheme: the upper fixed one of base 60 cooresponding mutually by on cut assembly and cut the support that assembly (40,50) constitutes down, on cut the table top 30 of the upper fixed one elevate a turnable ladder weight of assembly, have support and cut the hydraulic power system that assembly bracket makes that table top 30 rises up and down.Hydraulic power system is made up of electric box, Hydraulic Station 70, actuator cylinder 20 and tight automatically lock and release mechanism.Wherein automatic unlocking and catch gear mainly comprise two toothed rack 8, two ratchets 9 and valve control electromagnets 6.In the both sides of hydraulic ram 20, other end sky is enclosed within on the earrings axle 15 of oil cylinder piston bar 16 one end of two toothed rack 8 by connecting panel 1, step axle 5, cone pulley 3 and bolt and nut contact.Two ratchets 9 are loaded on the two ends of axle 7 respectively, and axle 7 is fixed on the seat board 14 that is welded on the cylinder body 20, and 7. valve control electromagnet 6 also is fixedly connected on the seat board 14 by screw.On cut with the contact point of cutting down assembly bracket (40,50) and base 60, table top 30 in the upper and lower fulcrum in the left side be the hinge type of attachment, the upper and lower fulcrum in the right is provided with the roller that can roll on base and table top raceway.

The utility model complete machine falls into melt pit, does not account for the place, and the vehicle turnover is convenient freely, and the industrial building can be used on a ground more; Jacking capacity is big, can use for multiple vehicle; The Hydraulic Synchronizing device make dipping and heaving steadily, reliable, can highly overhaul in stop arbitrarily, and car door can be opened fully; Automatic self-locking that the lifting stand is firm, the mechanical type ratchet is furnished with valve control electromagnet simultaneously and release insurance guarantee that job safety is reliable; Be furnished with lighting source under the car, the external source output socket can connect various power tools, and is easy to use.

The utility model description of drawings:

Fig. 4 is the A-A view to the left among Fig. 3.

Fig. 5 is that K among Fig. 3 is to birds-eye view.

In conjunction with the accompanying drawings detailed structure of the present utility model and principle thereof are further described:

On to cut with cutting down being connected of each point be to be equipped with the roller with the contacted scissors leg ends of table top and with the contacted scissors of base end except that the right, all the other each points are the hinge connection.One end of oil cylinder 20 is fixed on the base 60, and an end of oil cylinder piston bar 16 links to each other with shear shank by earrings axle 15.One end of two parallel racks 8 by connecting panel 1 bolt 10., step axle 5 and acorn nut are 8., cone pulley 3 etc. interrelates with oil cylinder 20, the other end then sky is enclosed within on the oil cylinder piston bar earrings axle 15, when the piston rod 16 of oil cylinder 20 stretches, then drive tooth bar 8 and make corresponding mobile thereupon, this hour rack 8 promotes connecting panel 1 and does corresponding the rolling by two rollers 3 along the oil cylinder cylindrical, thereby finishes steadily moving of tooth bar.4. two ratchets 9 are loaded on respectively on the axle 7 and with taper pin prevents claw stop and interaxle relatively rotating, and 7 on axle is contained on the seat board 14 that is welded on the cylinder body 20, and axle 7 can rotate on seat board 14.When resting on a certain locus in the lifting machine process of rising or falling, can ratchet be inserted between rack tooth automatically, thereby finish locking function.When the lifting machine rises or descend,,, ratchet finishes the automatic unlocking function thereby being lifted by the effect of valve control electromagnet 6.

It is that push rod by valve control electromagnet 6 stretches out with withdrawal and promotes to be contained in roller 13 on the roller mount 12 that ratchet lifts with falling automatically, moves axially and promote roller mount 12, thereby drives back plate 11 rotations.There is a via hole back plate 11 upper ends, with nut back plate upper end are fixed on the roller mount 12, and the lower end of back plate 11 is contained in the axial dead slot of axle 7 and is connected with spools 7 with two flathead screws 13.So, when roller 12 moves axially, just pass through the swing of the lower end of back plate 11, rotations that make axle 7 produce certain angles are rotated and drive ratchet, finish function engaging-in or the disengagement tooth bar.The compression spring 10 of roller mount 12 ends plays the reset response that makes roller mount 12, promptly makes ratchet in time fall into reliably in the tooth bar teeth groove.

7. four fillister head screws of valve control electromagnet 6 usefulness are connected on the seat board 14, and left end ratchet auto lock and release mechanism then seal with

dihedral cover plate

4, and 5. are connected on the seat board 14 the supporting position that described dihedral cover plate also is a roller mount 12 by four dish screws.

The lifting machine is not when using, and table top and ground are in same plane.When the place under repair operation, automobile sails lifting board face into along accompanying drawing 2 directions of arrow, and below vehicle body, add high body cushion block, press the rising button, then hydraulic efficiency pressure system turns round, drive actuator cylinder 20 and make it to promote to cut assembly 40 and cut assembly 50 down, the roller by the scissors leg end rolls along track, thereby stops after promotion table top 30 maintenance levels rise to desired location.As for the control of the rising extreme higher position of table top, then form switch and realize by the collision of roller end.At this moment by multiple interlocking safety device, guarantee that repair work safety is perfectly safe, in the operation process or during the end of job, can table top be descended by the decline button of pressing on the electric box as required.For this reason, the lifting prow is finished automatic unlocking motion earlier, is automatically converted to descending motion then, after confirming that the lifting table top falls go back to ground fully, unclamps the decline button, can roll away to be repaired.
