Description
- The present invention relates to a gripping structure of elevator ropes. Embodiments of the present invention may be used in a traction-type elevator.
- In a conventional elevator, the ends of the ropes that suspend the elevator car or the counterweight are gripped by a plurality of rope grippers. The rope grippers are parallelly arranged, and supported by a supporting part provided on, for example, the machineroom floor, via elastic bodies such as coil springs or the like.
- Here, in such a case where the elevator car is stopped at the lowest floor, that is, in the case where there is ample distance between the rope grippers and the suspension sheave for the car mounted on the elevator car, the rope grippers are supported almost vertically by the supporting part. However, when the rope grippers and the suspension sheave for the car get close to each other according to the ascent or descent of the elevator car, the distances between the elevator ropes in the vicinity of the rope grippers become short, and there is the fear of mutual interference of the rope grippers. For this reason, in order to solve this problem, it is necessary to widen the arrangement interval between the rope grippers at the supporting part, or to enlarge the clearance in the top part of the hoistway, i.e., the distance between the suspension sheave for the car and the rope grippers in the case where the elevator car becomes the closest to the rope grippers. As a result of this, the problem that the space occupied by the elevator becomes large arises.
- Furthermore, in Japanese unexamined laid-open utility model publication No.
Sho 52-27052 - The present invention has as its object the prevention of mutual interference of the rope grippers without widening the arrangement interval between the rope grippers at the supporting part or enlarging the clearance in the top part of the hoistway, as in the conventional way.
- Reference is also made to
JP 2003 002558 A - The invention is defined by the independent claim below. Dependent claims are directed to optional features and preferred embodiments.
- Disclosed is a gripping structure of elevator ropes which comprises a plurality of rope grippers which grip an end of each rope of a plurality of parallel elevator ropes, and a supporting part which supports the plurality of rope grippers. A rope regulator with through holes corresponding to each rope of the plurality of elevator ropes is arranged in the vicinity of the rope grippers, and each rope of the plurality of elevator ropes is passed with a gap through the through holes of the rope regulator and gripped by a rope gripper.
- Furthermore, the rope regulator is suspended by a flexible member, and the flexible member is fastened to the rope grippers or to the supporting part.
- Moreover, at least around the inner wall of the through holes of the rope regulator is formed of a material softer than the material of the outer layer of the elevator rope.
- According to the aforementioned configuration, it is possible to prevent mutual interference of the rope grippers without widening the arrangement interval between the rope grippers at the supporting part or enlarging the clearance in the top part of the hoistway, and to secure the original durability of the rope grippers. Moreover, since the elevator ropes are passed with a gap through the rope regulator, and more preferably, the rope regulator is formed of a material softer than the material of the outer layer of elevator rope, damage to the elevator ropes may be prevented, and the original durability of the elevator rope may be secured.

-
Figure 1 is a diagram illustrating a gripping structure of elevator ropes in accordance with the first embodiment of the present invention; andFigure 2 is a cross-sectional view taken on line A-A. - In
Figure 1 , theelevator ropes 5, which are arranged in parallel, have one end passed around asuspension sheave 4 that is provided at an upper part of theelevator car 3 that ascends and descends through thehoistway 1. Each of theelevator ropes 5 has an end gripped by a plurality ofrope grippers 6. Therope grippers 6 are arranged in parallel, and are fastened with nuts 9 to a supportingpart 7 which is provided on themachineroom floor 2 via elastic bodies formed ofcoil springs 8. - Next: a
rope regulator 10 is arranged in the vicinity of therope grippers 6. As shown inFigure 2 , therope regulator 10 has a plurality of throughholes 15 which are formed by assembling twoouter plates 11 and aninner plate 12 which all have semicircle-shaped grooves. Theouter plates 11 and theinner plate 12 are fixed withthroughbolts 13 andnuts 14. These throughholes 15 are formed so as to correspond to eachrope 5 of the plurality ofelevator ropes 5, and theelevator ropes 5 are passed with a gap through the throughholes 15. That is, the diameter of the throughholes 15 of therope regulator 10 is formed to be larger than the diameter of theelevator ropes 5. Furthermore, the throughholes 15 are provided at an interval in which therope grippers 6 do not interfere with each other in the case where theelevator car 3 is stopped at the highest floor, i.e., in the case where the rope grippers 6 and the suspension sheave 4 on the upper part of thecar 3 become the closest. - Moreover, the
rope regulator 10 is formed of a material softer than the material of the outer layer of thesteel elevator ropes 5, for example, synthetic resin such as polyethylene or wood. That is, the material used for therope regulator 10 is a material that does not damage theelevator ropes 5 when touched by theropes 5. - Furthermore, since the
elevator ropes 5 is passed with a gap through therope regulator 10, in order to maintain therope regulator 10 in the vicinity of therope grippers 6, therope regulator 10 is suspended by aflexible member 17. Both ends of theflexible member 17 are fastened to therope grippers 6. Therope grippers 6 are in positions near therope regulator 10, thus they are suitable as locations to which theflexible member 17 is to be fastened. As theflexible member 17, a wire, for example, is used; however, other objects may also be used as long as they are capable of supporting the weight of therope regulator 10 without problems. - According to the above-described first embodiment, the
elevator ropes 5, which have an end gripped by a plurality ofrope grippers 6 arranged in parallel, are passed through throughholes 15 that are formed in therope regulator 10 and maintained at a designated interval. For this reason, even in the case where thesuspension sheave 4 becomes close to therope grippers 6 due to the ascent and descent of theelevator car 3, although the elevator ropes 5 in the vicinity of therope grippers 6 tend to approach each other, mutual interference of therope grippers 6 is avoided since the positions of theropes 5 are maintained because theropes 5 touch the throughholes 15. - Moreover, the
elevator ropes 5 are passed with a gap through therope regulator 10, thus theelevator ropes 5 may rotate in the circumferential direction against the throughholes 15. For this reason, even in the case where untwisting of theelevator ropes 5 occurs, no load is applied to the ropes since theelevator ropes 5 are not caught by therope regulator 10. Accordingly, the durability of theelevator ropes 5 is not damaged. - Furthermore, since the
elevator ropes 5 are movable also in the longitudinal direction of theropes 5, in the case where the tension of theelevator ropes 5 is to be adjusted at maintenance, it is possible to adjust the tension of each of theelevator ropes 5 without removing therope regulator 10. - Moreover, since the
rope regulator 10 is formed of a material softer than the material of the outer layer of theelevator ropes 5, even in the case where the elevator ropes 5 touch therope regulator 10, it is possible to avoid damage to theelevator ropes 5. -
Figure 3 is a cross-sectional view illustrating the rope regulator in accordance with the second embodiment of the present invention. - Also in the second embodiment, a
rope regulator 10 is arranged in the vicinity ofrope grippers 6 and therope regulator 10 is suspended by aflexible member 17 in accordance withFigure 1 , as in the first embodiment. Further, both ends of theflexible member 17 are fastened to therope grippers 6. - Here, as shown in
Figure 3 , also in the second embodiment, therope regulator 10 is formed by assembling twoouter plates 11 and aninner plate 12. However, only around theinner wall 16 of the throughholes 15 of therope regulator 10, through which theelevator ropes 5 are passed, is formed of a material softer than the material of the outer layer of theelevator ropes 5 such as a synthetic resin material such as polyethylene or the like. Also by this type of formation, it is possible to avoid damage to theelevator ropes 5 in the case where the elevator ropes 5 touch therope regulator 10. The other structures are the same as the first embodiment, so the same numerals are given to the same parts or the corresponding parts, and repeated explanation will be omitted. - According to the aforementioned second embodiment,
elevator ropes 5 which have an end gripped by therope grippers 6, are passed through throughholes 15 that are formed in therope regulator 10 and maintained at a designated interval. For this reason, even in the case where thesuspension sheave 4 becomes close to therope grippers 6 due to the ascent and descent of theelevator car 3, although theelevator ropes 5 in the vicinity of therope grippers 6 tend to approach each other, mutual interference of therope grippers 6 is avoided since the positions of theropes 5 are maintained because theropes 5 touch the through holes 15. - Moreover, since only around the
inner wall 16 of the throughholes 15 of therope regulator 10 is formed of a material softer than the outer layer of theelevator ropes 5, even in the case where the necessity for replacement of therope regulator 10 arises in the future, it is not necessary to replace thewhole rope regulator 10, but only around theinner wall 16 of the throughholes 15 of therope regulator 10. - In addition to the above, the same effects as the first embodiment may be attained.
-
Figure 4 is a diagram illustrating a gripping structure of elevator ropes in accordance with the third embodiment of the present invention. - Also in the third embodiment, a
rope regulator 10 is arranged in the vicinity ofrope grippers 6 , and therope regulator 10 is suspended by aflexible member 17. - Here, as shown in
Figure 4 , unlike in the first embodiment, both ends of theflexible member 17 are fastened to a supportingpart 7. It is also possible to have therope regulator 10 held in this kind of manner; and to which of therope grippers 6 or the supportingpart 7 theflexible member 17 is to be fastened may be suitably decided taking the workability at installation of the equipment into consideration. - Next: as shown in
Figure 2 , thewhole rope regulator 10 may be formed of a material softer than the material of the outer layer of theelevator ropes 5. It is also possible to form only around theinner wall 16 of the throughholes 15 of therope regulator 10 of a material softer than the material of the outer layer of theelevator ropes 5. The other structures are the same as the first and second embodiments, so the same numerals are given to the same parts or the corresponding parts, and repeated explanation will be omitted. - According to the aforementioned third embodiment, the
elevator ropes 5, which have an end gripped by a plurality ofrope grippers 6 arranged in parallel, are passed through throughholes 15 that are formed in therope regulator 10 and maintained at a designated interval. For this reason, even in the case where thesuspension sheave 4 becomes close to therope grippers 6 due to the ascent and descent of theelevator car 3, although theelevator ropes 5 in the vicinity of therope grippers 6 tend to approach each other, mutual interference of therope grippers 6 is avoided since the positions of theropes 5 are maintained because the ropes touch the through holes 15. - In addition to the above, the same effects as the first and second embodiments may be attained.
- In the above-described embodiments, explanation on the end of the
elevator ropes 5 at the side of theelevator car 3 is given; however, since the other end of theelevator ropes 5 that extend from theelevator car 3 and are passed around the suspension sheave of the counterweight via the hoisting machine is of the same formation, explanation will be omitted. - Furthermore, in the above-described embodiments, an example wherein the supporting
part 7 is provided on themachineroom floor 2 is given. However, there are cases in which the supportingpart 7 is provided at an upper part of the hoistway via a support bench, or on the upper surface of the elevator car or of the counterweight via a beam. In these cases and also in other cases, the gripping structure of elevator ropes in accordance with the present invention may be applied. - As aforementioned, in the gripping structure of elevator ropes in accordance with the present invention, elevator ropes are passed with a gap through a rope regulator in the vicinity of rope grippers. Thus, it is possible to prevent mutual interference of the rope grippers and to secure the original durability of the rope grippers without widening the arrangement interval between the rope grippers at the supporting part or enlarging the clearance at the top part of the hoistway. Furthermore, since the elevator ropes are passed with a gap through the rope regulator, and preferably the rope regulator is formed of a material softer than the outer layer of the elevator ropes, damage to the elevator ropes may be prevented, and the original durability of the elevator ropes may be secured.
- Accordingly, embodiments of the present invention are useful as gripping structures of elevator ropes wherein durability of the rope grippers and the elevator ropes and savings in space may be improved.
