Abstract
The utility model relates to a diameter different winding engine which is also composed of an electromotor 8, wound rolls, a rope 9, etc. The utility model is characterized in that each of the wound rolls is divided into a thick and a thin sections, and the two end sections of the rope are respectively wound on a major diameter wound roll 6 and a minor diameter wound roll 7; when the wound rolls rotate, one side of the rope rises, the other side of the rope descends, while the speeds of both sides of the rope are unequal to each other; thus, the operation of lifting and lowering heavy objects can be carried out. Without a decelerator, the winding engine still can realize a large transmission ratio; at the same time, as the force moments of the two sections of the rope to the shaft centers of the wound rolls are mutually canceled, lifting torque can be lowered. Therefore, the utility model has the advantages of simplified structure, deadweight and fabricating cost reduction, performance improvement and convenient transportation and installation.
Description
The utility model is a kind of mechanical device, promptly a kind of difference footpath winch that is used for hoisting heavy.
The purposes of winch is a lot, as hoisting heavy, and gate opening/closing in the hydraulic engineering or the like.Present winch is many by engine, formations such as speed reduction gearing, reel, rope.This winch, complex structure, weight is big, and the expense of price and transportation, installation is all than higher.
The purpose of this utility model is that development is a kind of simple in structure, and it is less to conduct oneself with dignity, and cost is low, transports and install all winch eaily.
Technical scheme: this winch also is to be made of engine, drg, reel, rope etc., different is: said reel is the reel that is not waited by two sections diameters, promptly big footpath reel and path reel constitute, the two ends section of lifting rope is wrapped in respectively on two sections reels, when reel rotated, the rope that is wrapped on the two winding drum moved towards opposite up and down.
But said big footpath reel is with the path reel with coaxial integral body.
Said big footpath reel and path reel can be tapered drums.
Said big footpath reel and path reel can be two disalignment reels.
Also can assemble the reducing watt plate that changes external diameter on the said reel.
The winch that adopts such scheme to make, rope is entangled on the different reel of thickness, when reel rotates, has on rope has down, put while twining, but speed does not up and down wait, thereby can realize landing to weight.This difference footpath reel has replaced speed reduction gearing in the past, and structure is greatly simplified.In addition, for coaxial reel,, make the starting torque of hoisting heavy greatly reduce because two sections ropes are cancelled out each other to the moment major part in reel axle center.Thereby reached simple in structure, cost is low, the purpose of easy transportation and installation.
Introduce three kinds of embodiment below in conjunction with accompanying drawing.
Fig. 1 is the front view of first kind of embodiment, and Fig. 2 is its left view, and Fig. 3 is its birds-eye view.
Among the figure as seen, frame 1, drum shaft 2, bearing 3, worm gear 4, worm screw 5, big footpath reel 6, path reel 7, electrical motor 8, rope 9, pulley 10, drg 11.
As shown in the figure, the reel of this winch is divided into two sections of thicknesses, and rope ends is wrapped in respectively on one section reel, articulates weight below by pulley 10.When big footpath reel 6 coiling ropes, rope on the path reel 7 is decontroled, because the radius difference, up rope lengths is greater than descending rope lengths, thereby can the lifting weight.Otherwise, rouleau tube coiling rope, parent roll is decontroled rope, and up rope is less than descending rope, promptly carries out weight landing process.
This reel can be driven by worm gear 4, worm screw 5 by motor 8, and can realize bigger transmitting ratio by the diameter difference of two winding drum.In addition, can also change its diameter, thereby reach the purpose that changes transmitting ratio by reel being installed additional modes such as arc watt plate.
Second kind of embodiment: reel is conical cylinder, and big end and small end are arranged, and also can reach the purpose of first kind of embodiment.
The third embodiment: two sections reel disalignments that diameter is different, parallel axes or installation at an angle, be provided with transmission gear between the two winding drum, and be all mutually with rotating speed, also can achieve the above object, but structure is comparatively complicated, be suitable for the installation site be restricted or other certain conditions under use.
Claims (5)
1, a kind of poor directly winch, also be by engine (8), brake equipment, reel, rope formations such as (9), it is characterized in that: said reel is the reel that is not waited by two sections diameters, promptly big footpath reel (6) and path reel (7) constitute, the two ends of lifting rope (9) are wrapped in respectively on two sections reels, when two sections reels rotated, the rope that is wrapped on the two winding drum moved towards opposite up and down.
2, poor directly winch according to claim 1, it is characterized in that: said big footpath reel (6) is with path reel (7) but with coaxial integral body.
3, poor directly winch according to claim 1, it is characterized in that: said big footpath reel (6) can be a tapered drum with path reel (7).
4, poor directly winch according to claim 1, it is characterized in that: said big footpath reel (6) can be two disalignment reels with path reel (7).
5, poor directly winch according to claim 1 is characterized in that: also can assemble the reducing watt plate that changes external diameter on the said reel.
