A kind of transversely movable double pulleies unit vertical lifting equipment
Technical field
The present invention relates to a kind of transversely movable double pulleies unit vertical lifting equipment.
Background technology
Prior art exists a kind of vertical lifting equipment, including frame, rigidly-fixed power plant in frame, pay off rack, fixed pulley group, pleasure boat frame, power set drive pay off rack folding and unfolding pull rope, the pull rope drawn by pay off rack is successively via pleasure boat frame, fixed pulley group guides, pull rope drives and connects suspender, the existing suspender for hoisting heavy includes suspension hook, suspension hook is connected with pull rope, in suspender use procedure, serious wear between pull rope and suspension hook, long-time use, may result in fracture, security incident occurs, simultaneously, crossbeam is installed after fixing, its lifting position can be fixed, if again to lift by crane elsewhere, need mobile and retighten crossbeam, waste time and energy, urgently improve.
Summary of the invention
For prior art Problems existing, it is an object of the invention to propose a kind of transversely movable double pulleies unit vertical lifting equipment, can vertical lifting weight, and adopt the dynamic friction of many pull ropes to replace the static friction of single pull rope, make to reduce the pressure-bearing of pull rope and the abrasion of pull rope and equipment as far as possible, so that in use safer, and when needing the weight that lifting horizontal level is different again, it is not necessary to dismantle whole equipment.
For reaching this purpose, the present invention by the following technical solutions:
A kind of transversely movable double pulleies unit vertical lifting equipment, including frame, frame is fixing connects the first power set, pay off rack, pleasure boat frame, suspender, slide rail, second power set, slide rail is slidably connected the first fixed pulley group, second fixed pulley group, driven by the second power set, first fixed pulley group, second fixed pulley group can be slided on slide rail, first power set drive pay off rack folding and unfolding pull rope, the pull rope drawn by pay off rack is successively via pleasure boat frame, first fixed pulley group, second fixed pulley group guides, suspender includes suspension hook, the supporting seat of fixing suspension hook, it is rotationally connected the first pulley of supporting seat, second pulley, first fixed pulley group is driven by pull rope and connects the first pulley, second fixed pulley group is driven by pull rope and connects the second pulley.First power set and pleasure boat frame are placed in frame both sides, and the first fixed pulley group, the second fixed pulley group are between the first power set and pleasure boat frame.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention is possible not only to realize vertical lifting weight, and adopt the dynamic friction of many pull ropes to replace the static friction of single pull rope, make to reduce the pressure-bearing of pull rope and the abrasion of pull rope and equipment as far as possible, so that it is in use safer, and when needing the weight that lifting horizontal level is different again, it is not necessary to dismantle whole equipment.

Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention:
Embodiment 1
nullA kind of transversely movable double pulleies unit vertical lifting equipment is proposed,Including frame 1,Frame 1 is fixing connects the first power set 2、Pay off rack 3、Pleasure boat frame 6、Suspender、Slide rail 11、Second power set 10,Slide rail 11 is slidably connected the first fixed pulley group 51、Second fixed pulley group 52,Driven by the second power set 10,First fixed pulley group 51、Second fixed pulley group 52 can be slided on slide rail 11,First power set 2 drive pay off rack 3 folding and unfolding pull rope 4,The pull rope 4 drawn by pay off rack 3 is successively via pleasure boat frame 6、First fixed pulley group 51、Second fixed pulley group 52 guides,Suspender includes suspension hook 8、The supporting seat 9 of fixing suspension hook 8、It is rotationally connected the first pulley 71 of supporting seat 9、Second pulley 72,First fixed pulley group 51 is driven by pull rope 4 and connects the first pulley 71,Second fixed pulley group 52 is driven by pull rope 4 and connects the second pulley 72.First power set 2 and pleasure boat frame 6 are placed in frame 1 both sides, and first fixed pulley group the 51, second fixed pulley group 52 is between the first power set 2 and pleasure boat frame 6.
nullDisclosing of technique scheme,Hoisting heavy can be realized,First fixed pulley group 51 is driven by pull rope 4 and connects the first pulley 71,Second fixed pulley group 52 is driven by pull rope 4 and connects the second pulley 72,Pull rope 4 is made to coordinate the first pulley 71、Second pulley 72,Make pulling the first pulley 71 by pull rope 4、During the second pulley 72,By the first pulley 71、Second pulley 72 uses as movable pulley,So that pulling the first pulley 71、In the process that second pulley 72 rises,Sliding friction is made to replace static friction,Make pull rope 4 and the first pulley 71、Abrasion between second pulley 72 is minimum,To ensure safety,Additionally,Owing to this device comprising the first pulley 71、Second pulley 72,The pulling force that can ensure that weight in the process drawing lift heavy thing is not only made to be shared by four pull ropes 4,Pull rope 4 is made to be not susceptible to fracture,And weight can be made more stable in drawing the process of hanging,It is not susceptible to security incident.When needing other position hoisting heavies again in the horizontal direction, it is only necessary to promote first fixed pulley group the 51, second fixed pulley group 52 to slide on slide rail 11 by the second power set 10, thus adjusting the horizontal level of suspension hook 8.This device is possible not only to realize vertical lifting weight, simple in construction, it is easy to install, it is easy to carrying, and when needing the weight that lifting horizontal level is different again, it is not necessary to dismantle whole equipment.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
