Abstract
The utility model discloses a vertical hoisting device with double assembly pulleys. The vertical hoisting device comprises a frame. A power device, a pay-off rack, a first fixed pulley set, a second fixed pulley set, a loose pulley rack and a suspender are fixed on the frame, wherein the power device drives the pay-off rack to release and withdraw a haulage rope, the haulage rope led out from the pay-off rack is guided sequentially by the loose pulley rack, the first fixed pulley set and the second fixed pulley set, the suspender comprises a suspension hook, a supporting seat for fixing the suspension hook, and a first pulley and a second pulley rotatably connected to the suspension hook, the first fixed pulley is in driving connection with the first pulley through a cable, and the second fixed pulley set is in driving connection with the second pulley through a cable. The vertical hoisting device vertically lifts heavy objects. Static friction of a single cable is replaced by kinetic friction of plurality of cables, which reduces the bearing force of the cable and minimizes wearing of the cables and the device. The vertical hoisting device is safer to use.
Description
Technical field
The utility model relates to a kind of sister block group vertical lifting equipment.
Background technology
There is a kind of vertical lifting equipment in the prior art, comprise frame, rigidly-fixed power plant, pay off rack, fixed pulley group, pleasure boat frame on the frame, engine installation drives pay off rack folding and unfolding hauling rope, guided via pleasure boat frame, fixed pulley group successively by the hauling rope that pay off rack is drawn, hauling rope drives and connects suspender, existing suspender for hoisting heavy comprises suspension hook, suspension hook links to each other with hawser, in the suspender use procedure, and serious wear between hawser and the suspension hook, the long-time use, may cause fracture, safety misadventure occur, demand urgently improving.
The utility model content
Problem for the prior art existence, the purpose of this utility model is to propose a kind of sister block group vertical lifting equipment, but vertical lifting weight, and the dynamic friction of adopting many hawsers replaces the static friction of single cable, so that reduce the pressure-bearing of hawser and the wearing and tearing of hawser and equipment, thereby so that in use safer as far as possible.
For reaching this purpose, the utility model by the following technical solutions:
A kind of sister block group vertical lifting equipment, comprise frame, frame rigidly-fixed power plant, pay off rack, the first fixed pulley group, the second fixed pulley group, pleasure boat frame, suspender, engine installation drives pay off rack folding and unfolding hauling rope, guided via pleasure boat frame, the first fixed pulley group, the second fixed pulley group successively by the hauling rope that pay off rack is drawn, suspender comprises suspension hook, fixedly supporting seat, the first pulley that is rotationally connected supporting seat, second pulley of suspension hook, the first fixed pulley group drives by hawser and connects the first pulley, and the second fixed pulley group drives by hawser and connects the second pulley.Engine installation and the pleasure boat frame frame both sides that are placed in, the first fixed pulley group, the second fixed pulley group are between engine installation and the pleasure boat frame.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model not only can be realized the vertical lifting weight, and adopts the dynamic friction of many hawsers to replace the static friction of single cable, so that reduce the pressure-bearing of hawser and the wearing and tearing of hawser and equipment as far as possible, thus so that in use safer.
Description of drawings
Fig. 1 is the integral structure schematic diagram of the utility model embodiment 1:
Wherein: 1, frame; 2, engine installation; 3, pay off rack; 4, hauling rope; 51, the first fixed pulley group; 52, the second fixed pulley group; 6, pleasure boat frame; 71, the first pulley; 72, the second pulley; 8, suspension hook; 9, supporting seat.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
A kind of sister block group vertical lifting equipment is proposed, comprise frame 1, frame 1 rigidly-fixed power plant 2, pay off rack 3, the first fixed pulley group 51, the second fixed pulley group 52, pleasure boat frame 6, suspender, engine installation 2 drives pay off rack 3 folding and unfolding hauling ropes 4, the hauling rope 4 of being drawn by pay off rack 3 is successively via pleasure boat frame 6, the first fixed pulley group 51,52 guidings of the second fixed pulley group, suspender comprises suspension hook 8, the fixing supporting seat 9 of suspension hook 8, be rotationally connected the first pulley 71 of supporting seat 9, the second pulley 72, the first fixed pulley group 51 drives connection the first pulley 71, the second fixed pulley groups 52 by hawser 4 and connects the second pulley 72 by hawser 4 drivings.Engine installation 2 and pleasure boat frame 6 frame 1 both sides that are placed in, the first fixed pulley group 51, the second fixed pulley group 52 are between engine installation 2 and the pleasure boat frame 6.
Disclosing of technique scheme, can realize hoisting heavy, the first fixed pulley group 51 drives by hawser 4 and connects the first pulley 71, the second fixed pulley group 52 drives by hawser 4 and connects the second pulley 72, make hawser 4 cooperate the first pulley 71, the second pulley 72, make and spurring the first pulley 71 by hawser, during the second pulley 72, with the first pulley 71, the second pulley 72 uses as movable pulley, thereby so that at pulling the first pulley 71, in the process that the second pulley 72 rises, make cliding friction replace static friction, make hawser and the first pulley 71, wearing and tearing between the second pulley 72 are minimum, to guarantee safety, in addition, owing to comprising the first pulley 71 in this device, the second pulley 72 not only makes the pulling force that can guarantee weight in the process of drawing the lift heavy thing be shared by four hawsers, so that hawser is difficult for fracture, and can make weight more stable in drawing the process of hanging, be difficult for occuring safety misadventure.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
