Abstract
The invention discloses a lifting tool. The lifting tool comprises a telescopic support arm, two pull ropes and a lifting hook, wherein two slide ways are arranged at the top end of the support arm and are arranged in a diverged manner; the two pull ropes are fixedly connected with the lifting hook respectively through the two slide ways. According to the lifting tool, the diverged slide ways are arranged at the top end of the telescopic support arm, and heavy objects are lifted by adopting the two ropes, so that the degree of swinging resulting from that the heavy objects are lifted by a single rope is reduced, the stability is strong, and the safety is high; the acting force is strong, and the operation is simple and convenient.
Description
Technical field
The present invention relates to engineering tools technical field, especially a kind of lifting device.
Background technology
Lifting appliance is widely used in the every field of productive life, and existing lifting appliance comprises suspension hook, stay cord and flexible lifting arm, when triggering weight process, often be difficult to the vertical property ensureing stay cord, this will inevitably produce and rock, and the efficiency of impact lifting, also can bring danger.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of lifting device, structure is ingenious, use safety.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of lifting device, comprising telescopic hold-down arm, stay cord and suspension hook, this hold-down arm top is provided with two slideways, for fork is arranged; This stay cord is set to two strands, is fixedly connected with respectively through two slideways with suspension hook.
Further, this suspension hook upper end is provided with reverse V-shaped pulley structure, and this reverse V-shaped two-arm is equipped with pulley, and two strands of stay cords are wrapped on two pulleys respectively.
Further, the exit of two passes is provided with the fixed pulley forming assembly pulley with pulley, and this stay cord is wound around assembly pulley.
Compared with prior art, the present invention has the following advantages: establish bifurcated slideway on retractable support arm top, adopts two strand ropes to realize pull-up weight, and reduce sub-thread rope and to sling the shaking degree of weight, stability is strong, and safety is high; And application force is strong, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of lifting device of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of lifting device as shown in Figure 1, comprises telescopic hold-down arm 1, stay cord 2 and suspension hook 3, and this hold-down arm 1 top is provided with two slideways 11, for fork is arranged; This stay cord 2 is set to two strands, is fixedly connected with respectively through two slideways 11 with suspension hook 3.
Hold-down arm 1 is arranged with the slideway that two are convenient to settle rope, and bifurcated is arranged, and makes two strands of stay cords 2 separately fixing suspension hook 3, guarantees two bursts of stay cord 2 institutes in the plane, not easily to shake, improve stability.
This suspension hook 3 upper end is provided with reverse V-shaped pulley structure 4, and this reverse V-shaped two-arm is equipped with pulley, and two strands of stay cords 2 are wrapped on two pulleys respectively.By reverse V-shaped pulley structure 4, utilize this movable pulley structure to reduce kinetic equation loss, reduce the friction force of stay cord 2 simultaneously, saved resource.
Corresponding with the movable pulley structure above suspension hook 3, be provided with the fixed pulley forming assembly pulley with pulley in the exit of two passes, this stay cord is wound around assembly pulley.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
