Description of invention (13) Miscellaneous and above and below the elevator shaft must maintain the above It can be seen that in the case of appropriately reducing the straightness of the moon wheel, the upper and lower positions of the elevator shaft can be two: 3 spaces' and the size of these spaces is completely based on the rope slip 3 疋 = right to the wheel 101 On the frame of the upper and / or car 101 and 2: in some cases, the design of all or part of the folding pulley is advantageous, and the traction sheave is advantageous, and in particular, it is arranged in the upper part. The deflecting pulley can have a larger size. For example, when =t is 4.1 and a folding pulley having a large size is provided on the upper portion of the elevator shaft, a space is available at the position where the rope passages are arranged. In addition to the above, the method can be applied to a lift having a machine room at the bottom, and also to an elevator having a machine room at the top. FIG. 3 is a partial cross-section of the rope pulley 2 according to the present invention. The rim of the plurality of rope grooves 2〇1 of the rim 2〇6 has a coating 202, and a space (51) is formed in the hub of the rope pulley 200: 6) 2〇3, whereby the space 2〇3 is used to accommodate the bearing used for the rope pulley 2〇〇. In addition, a plurality of holes 205 for bolts are formed on the rope pulley, and one side of the rope pulley can be fixed to the wrong tool in the driving machine 6 by the bolt passing through the hole 2〇5. That is, one side of the rope pulley can be fixed to one of the rotating flanges of the drive machine 6 by bolts through the holes 2〇5 to form a traction sheave. And in this example it is not necessary to separate the bearings in the traction sheave 7. Use 6038-5682-PF1(Nl).ptc Page 18 1286117 Case No. 92115007 发明5, invention description (14) The coating material on the traction sheave and rope pulley can be rubber (robber) Polyurethane or a similar elastomeric material that increases friction. In addition, if the material of the traction sheave and/or the rope pulley is simultaneously considered and selected under the material of the hoisting rope, the hoisting rope can still be attached to the rope pulley after the coating of the rope pulley is worn. Produces considerable bite force. Although the coating 2 〇 2 on the rope pulley 20 0 has been worn, there is still sufficient grip force (gri P ) between the rope pulley 2 〇〇 and the hoisting rope 3 when an emergency occurs. Thus, the elevator can ensure its functionality and operational reliability in the above-mentioned operation. In addition, in the manufacturing method of the rope pulley 200 and/or the rope pulley, only the rim 20 6 of the rope pulley 200 may be made of a material capable of increasing the grip force, thereby performing with the hoisting rope 3 For use with. When a high-strength hoisting rope with a smaller size than a normal rope is used, the size of the wheel and the rope pulley used in combination with the rope is smaller than that when the standard size rope (: rops) is used. The size of the rope pulley, = motor with smaller size and lower torque (secret or) 22:: The drive motor used, this can effectively reduce the power. For example, an elevator of the present invention having a nominal load of 1 000 kg is used, and 1 20-200 mm is preferred, but the straight line of the traction and the rare sheave is determined by the thickness. In the present invention:: root f; the use of the lifting rope, that is, i "lift with small diameter traction sheave" in the elevator with a front load of less than 1 〇〇〇 kg, which uses 6038 -5682-PFl(Nl).ptc Page 19 1286117

9211500L V. The weight of the drive machine of the invention (15) is about 1/2 of the weight of the drive machine currently used, that is to say the weight of the drive machine is about 100-150 kg or less than 100-150 kg. As apparent from the above description, the drive machine of the present invention includes a traction sheave, an electric motor, a machine housing structure, and brakes. The diameter of the traction sheave is determined by the thickness of the hoisting rope used. The ratio D/d between the diameter of the traction sheave and the thickness of the hoisting rope is 40 or less, where D is the diameter of the traction sheave and d is the thickness of the hoisting rope. In the case of damage caused by the wear resistance of the hoisting rope, the ratio D/d between the diameter of the traction sheave and the thickness of the hoisting rope is slightly reduced. On the other hand, by not increasing the service life (service 1 i fe), by increasing the number of hoisting ropes, it is possible to simultaneously reduce the D/d ratio, and the stresses of the hoisting ropes are small. of. Taking the ratio of D/d below 4 〇 as an example, the D/d value can be about 30, or D/d = 25 less than 30. Although it is compensated by the hoisting rope = the special structure, the diameter and the starting of the traction sheave are reduced! The ratio of D/d will also reduce the use of lifting weights. The D/d ratio on the service is by the specially designed hoisting rope with ^ * ”, 沄 沄 less than Μ, but the cost must be relatively high, the same purpose relative to the elevator shaft The weight of the support element of the machine is the weight of the support unit, the heavy machine and the crane is used to maintain the crane system only by a single: 1, 5 of the rated load of the machine. When the weight guide is used for support, Then = more f, the weight of the guide rails and / or support elements of the elevator can be about small weight machine and used to keep the crane; 1 / 6 or 1 / 8 of the neck load.

Invention description (16) Load 2:, heavy and 5, the front load indicates the load defined by the lift The supporting components of the elevator include a standard (b_Bu dripping crane #ΓΓ plus 1a/e) or a suspension bracket (SUSpensi〇n bracket), wherein the county has a wall structure for the elevator shaft (wa11 strUcture; Use the wall structure or top of the shaft above the guide or counterweight guide rail or clamp (cl_s), lifter; = = = = hang hang, where == = Supporting the crane to carry out the support. Without the support member, it is made to have a crane piano that is less than /, and has about 1/10 of the rated load. For the lift, the ratio between the =====easy is the actual weight of the counterweight and the rated load is the weight of the counterweight. The weight is ί1/2 rated load. For example, when the suspension ratio is 2:1:y, the diameter of the traction sheave is 160m and the load is 6, and the crane is crying and used to protect the surname. The diameter of the lifting rope is 4mm. The total weight of the combined secondary bearing member of the weight-only support member is approximately the load of the elevator = the embodiment of the crane, when the suspension ratio is 2: Q, u.

The embodiment is mainly for elevators with a rated load of 1 600 kg, wherein when the suspension ratio is 2 ··1, the diameter of the traction sheave is 240 mm and the diameter of the hoisting rope is 6 mm, the crane And the total weight of the support members for holding the crane is about 3 〇〇 kg, that is, the total weight of the crane and the supporting members for holding the crane accounts for about 1 / 7 of the rated load of the elevator. Therefore, the total weight of the crane and the supporting members for holding the crane can be achieved to a relatively low value by appropriately changing the suspension configuration of the hoisting rope. For example, when the suspension ratio is 4:

1. The diameter of the traction sheave is 16〇mm and the diameter of the lifting rope is 4mm. When used for an elevator with a rated load of 50 0kg, the total weight of the crane and the supporting components for holding the crane is about 5 〇kg. And the total weight of the crane and the supporting elements for holding the crane is about 1 / 10 of the rated load. However, even if the size of the traction sheave is substantially reduced and a higher suspension ratio is employed, it is not helpful to improve the motor torque output requirement required at the start state. For example, if the increased loss is neglected, if the suspension ratio is 4:1 instead of 2:1, and the diameter of the traction sheave is i6〇min instead of 400mm, then the motor torque output cannot be 1 / 5, and can reduce the actual size of the crane.

In practice, the coating of the rope pulley includes a plurality of groove-specific sub-coatings that are separated from each other, and must be detailed when making the coating of the rope I pulley or its characteristics. In addition, this coating can be formed on all the grooves in a continuous manner. The strain formed by the rope acting on the bottom of the rope groove can be completely avoided or reduced to a minimum value by the thickness of the coating on the side of the rope groove being smaller than the thickness of the coating at the bottom of the rope groove. . When the pressure is not released by the lateral direction, but can be guided by the combined effect of the shape of the substrate groove 220 and the thickness variation of the coating layer 20 (combi ned ef f ect ), the effect is on the rope. Lower values can be achieved with maximum surface pressures above the coating 202. Another method of fabricating the trench coating 202 similar to the above is to first fill the substrate trench 220 with a material for the coating, and then form a rope trench over the substrate trench 220. 201. The shape of the rope groove 201 is a good support effect, and the load-bearing surface layer at the bottom of the rope provides a good resistance to prevent the compressive stress generated by the circumferential rope.

It is known that the thickness of the steel wire in the rope is preferably between 0.15 mm and 0.5 mm, and the wire between the ranges can have quite good strength properties, and the individual wires can also be used. Provides sufficient wear resistance and a minimum impact on damage. The above discussion is mainly for the description of the round wire and the steei wires. Under the same principle, the rope can also be smashed in whole or in part by a non-circular steel wire (n〇n_r〇und steel). The cross-sectional area of the steel wire is substantially The cross-sectional area equal to the round steel and the wire is better, that is, the cross-sectional area of the steel wire 〇· 〇15 is off between 2 and 0.2 mm2. In this thickness range, the steel wire strength can be more than 2000 N/mm 2 A rope of between mm15mm2_〇.2mm2, and may also include a rope having a large cross-sectional area made of steel, for example, a rope made of Warrington c〇nstructi〇n. During the implementation of the invention, especially for wires having a strength range of 23 〇〇N/mm 2 _ 2700 N/mm 2 , the rope made of the wire in this range can have a considerable bearing capacity. Therefore, the rope for the elevator can be made by reinforcing the wire with high hardness. The coating thickness of the traction sheave suitable for such a rope is limited to less than.
