1be provided with counterweight.Further preferably, according to practical application, carrying section L can be made
1can carry and wait to draw object, buffer field L
2can be carried another wait to draw object.For all carrying the situation needing to draw object, such as in hoisting operations, when carrying section carries in time drawing object and rise to summit, buffer field drops to nadir, make buffer field carry another to wait to draw object, then run by reversion, make buffer field increase, carrying section declines, thus realizes the lifting effect of buffer field.Such lifting scheme also add the work efficiency of hoisting operations, saves the energy.
Counterweight can for the appearance rope device for storing and provide stepless rope.Holding rope device can be the proprietary container for holding stepless rope, also can as shown in this embodiment, make appearance rope device be configured to assembly pulley 3.Here, assembly pulley 3 is arranged to three rows, and each row can arrange multiple pulley, and the quantity of pulley can be determined according to the length of the stepless rope that will store and provide.By making the position of assembly pulley fix, location buffer field L further
2, make the buffer field L of stepless rope
2regularly be wrapped on assembly pulley, avoid being deposited in together mussily, prevent knotting and save space.
In a preferred embodiment, carrying section L
1also positioned by this assembly pulley, but also carrying section L can be shared by this assembly pulley
1load.As shown in Figure 3, carrying section L
1first turned to by the strong point 31 fixed point, then through two fixed pulleys, then reserve the part of carrying object.One of advantage of this embodiment is, the angle of two parts hauling rope of the carrying object of stepless rope is diminished, closer to parallel with the lead of object, thus cuts down the swing of stepless rope, make the process of traction object more steady.In addition, at buffer field L
2carry and wait to draw object, carrying section L
1when being provided with assembly pulley (not shown), assembly pulley can needing carrying section L according to assembling
1position, and share carrying section L further
1load, make carrying section L
1with buffer field L
2load coordinate mutually.
Here it is to be noted, the distance will drawn due to the draw gear in practical application is very long, and the radius of roll device that stepless rope reels is far smaller than the length that will draw, therefore two parts hauling rope of the carrying object of stepless rope is negligible relative to the angle of the lead of object.That is, 1/2nd of weight of object shared by every part hauling rope.Accordingly, Fig. 4 shows the schematic diagram of the relation between tractive force and trailed weight of object realized according to draw gear of the present invention.Embody the situation that draw gear draws object on the direction vertical relative to ground in this embodiment, wherein, stepless rope reels on such two roll devices, achieves such mechanical relationship:
(R
1-R
2) × G/2=F × R
1; That is, F/G=(R
1-R
2)/(2 × R
1).
Wherein, R
1the radius of parent roll, R
2be the radius of little reel, F is tractive force, and G is trailed object.Therefore, the ratio of F and G can have very large scope, and then realizes large-scale reduction ratio.And so large-scale reduction ratio is only had in the prior art and could be realized by large-scale retarding device.Obviously, draw gear of the present invention solves the excessive problem that takes up room, and then avoids the consumption of large-scale retarding device to mass energy.
In addition, draw gear also can draw object by other any direction spatially.As previously mentioned, draw gear of the present invention can according to actual needs such as except in elevator or other weight-lifting equipment for except vertical direction traction, can also aloft draw for horizontal direction in object transfer.Under special circumstances, draw gear of the present invention can also be utilized under the effect of auxiliary device along the direction of tilt traction object relative to ground.
