Description
Technical field
The present invention relates to a kind of and plates of automobile maintenance platform supporting draw tower.The invention still further relates to described using method of drawing tower.
Background technology
Existing stretching chain the inner of drawing tower is connected draws cat head bar upper end, and under the effect of king-post inner cylinder, push rod rises and drives the stretching chain and implemented to stretch in automobile deformed position and reset during work.In above-mentioned motion process, the stroke of oil cylinder piston bar, push rod and stretching chain is identical.
Use and to draw tower accordingly, the stretching chain does not have pretension with after automobile is connected, have only oil cylinder to move behind the segment distance, the stretching chain is just understood pretension, and oil cylinder delivery stroke afterwards is only the stretching travel that needs, and pretension stroke before is actually inevitable idle work.Such as, the oil cylinder fixed journey system is 257mm, in like manner, the maximum stroke movement of push rod also is 257mm, deduct above-mentioned pretension stroke after, the actual effectively stretching travel of stretching chain has only about 150mm.When caving in when dark in certain position to be repaired, once fixingly can not satisfy the stretching demand, also need the stretching chain is fixed again complex operation, inefficiency.And if address this problem by the mode that lengthens oil cylinder, the volume of oil cylinder will become greatly so, the speed of oil return will be corresponding slack-off, still influences operating efficiency.
On the other hand, when car roof position panel beating being resetted maintenance, the stretching chain need be by drawing the work of tower crane arm.Existing plates of automobile maintenance platform is with drawing in the tower crane arm mechanism, as the square tube of drawing the tower crane arm by two bolts with draw the cat head bar to link together.When work, draw the tower crane arm just to become a cantilever beam, the flexural deformation easily of stressed back.If drawing the tower crane arm to strengthen, will damage drawing the cat head bar.
Summary of the invention
Technical problem to be solved by this invention is, a kind of plates of automobile maintenance La Ta and drawing process thereof are provided, the first, according to action need, the stretching chain has two kinds of strokes, strokes such as a kind of and oil cylinder piston bar, second kind is the twice of the oil cylinder piston throw of lever, and two kinds of strokes are distinguished or the merging use, to overcome the existing ineffective defective of tower of drawing.The second, make and to draw the tower crane arm stressed more reasonable, can flexural deformation after stressed.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme that adopts:
A kind of plates of automobile maintenance is with drawing tower, comprise king-post, be installed in the oil cylinder in the king-post, be installed in the king-post and by the push rod of hydraulic oil cylinder driving and by the stretching chain of top rod driving, also comprise the guiding wheel seat that is installed on the king-post, be connected with the chain directive wheel on this guiding wheel seat, it is characterized in that: the upper end of described push rod is provided with turning rolls, at this turning rolls roller is installed; Described stretching chain is walked around described roller and chain directive wheel successively; Offer the clamp draw-in groove on the described turning rolls; Also comprise for being plugged on described clamp draw-in groove the stretching chain is fixed on chain clamp on the turning rolls; Offer the chain clamp bar slot that cooperates with described clamp draw-in groove on the described chain clamp.
Side by side two about described roller is preferably.
Also comprise and be clamped on the described king-post and be positioned at the lower support element of described guiding wheel seat below and the transverse arm on the inner wheel shaft that is connected described chain directive wheel; Also comprise the oblique arm that lower end and described lower support element are hinged, be connected to each other between oblique arm and the transverse arm; And be provided with the oblique arm directive wheel in oblique arm upper end; The stretching chain is also walked around the oblique arm directive wheel after walking around roller and chain directive wheel successively.
Offer several transverse arm locating holes on the described transverse arm, offer several oblique arm locating holes on described this oblique arm; Link together by the bolt that is plugged on simultaneously in described transverse arm locating hole and the oblique arm locating hole between oblique arm and the transverse arm.
Use the described plates of automobile maintenance drawing process that draws tower, it is characterized in that:
When the panel beating reparation needs big pulling force, utilize the chain clamp that the stretching chain is blocked, strokes such as stretching chain and oil cylinder piston bar are exported bigger pulling force; Perhaps, in stretching pretension process, chain is moved at roller, the stretching chain is the twice of the oil cylinder piston throw of lever, exports less pulling force; After pretension puts in place, utilize the chain clamp that the stretching chain is blocked, strokes such as stretching chain and oil cylinder piston bar are exported bigger pulling force;
When the panel beating reparation needs less pulling force, chain is moved at roller, the stretching chain is the twice of the oil cylinder piston throw of lever, exports less pulling force.
Good effect of the present invention is:
The present invention has utilized the operation principle of movable pulley, and the stretching chain has two kinds of strokes, and strokes such as a kind of and oil cylinder piston bar are exported bigger pulling force; Second kind is the twice of the oil cylinder piston throw of lever, exports less pulling force but has saved oil cylinder stroke.
Such as, the stroke of oil cylinder is 257mm, so, the exportable stroke of chain just can reach 514mm, has increased effective tensile elongation of chain greatly, has improved operating efficiency.
Movable pulley reaches the labour-saving purpose by sacrificing active length, counter pushing away in like manner, and the tensile force of stretching chain output on automobile also dwindled half, such as, the La Tala oil cylinder power of stretching is 10 tons, so, the active force that acts on the automobile has just become 5 tons.Generally, when repairing automobile, 5 tons active force can satisfy big extremely department work requirements.If the power that maintenance needs has exceeded 5 tons really, utilize the chain clamp that the stretching chain is blocked, just can guarantee that the power output of chain reaches 10 tons, in this state, the stretching distance of chain also just has only 257mm.
Therefore, according to the practical operation needs, the present invention can selectively export two kinds of strokes, and the drawing process of two kinds of strokes uses respectively or merges use, has increased substantially the operating efficiency of drawing tower on the whole.
Car roof position panel beating is being resetted when maintenance, the stretching chain passes to the diverse location of king-post with the power that is subjected to by oblique arm and transverse arm, and oblique arm is subjected to the dual support of lower support element and transverse arm simultaneously, thus oblique arm is stressed can flexural deformation.
By adjusting the height of lower support element and upper supporting piece, and adjust the various combination between a plurality of transverse arm locating holes and a plurality of oblique arm locating hole, in the time of can adapting to work to the needs of different stretch position height and stretching angle.
