  • 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.
  • 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.
  • 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.
  • the rope regulator is suspended by a flexible member, and the flexible member is fastened to the rope grippers or to the supporting part.
  • 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.
  • 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.
  • 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
  • Figure 2 is a cross-sectional view taken on line A-A.
  • the elevator ropes 5 which are arranged in parallel, have one end passed around a suspension sheave 4 that is provided at an upper part of the elevator car 3 that ascends and descends through the hoistway 1.
  • Each of the elevator ropes 5 has an end gripped by a plurality of rope grippers 6.
  • the rope grippers 6 are arranged in parallel, and are fastened with nuts 9 to a supporting part 7 which is provided on the machineroom floor 2 via elastic bodies formed of coil springs 8.
  • a rope regulator 10 is arranged in the vicinity of the rope grippers 6.
  • the rope regulator 10 has a plurality of through holes 15 which are formed by assembling two outer plates 11 and an inner plate 12 which all have semicircle-shaped grooves.
  • the outer plates 11 and the inner plate 12 are fixed with throughbolts 13 and nuts 14.
  • These through holes 15 are formed so as to correspond to each rope 5 of the plurality of elevator ropes 5, and the elevator ropes 5 are passed with a gap through the through holes 15. That is, the diameter of the through holes 15 of the rope regulator 10 is formed to be larger than the diameter of the elevator ropes 5.
  • the through holes 15 are provided at an interval in which the rope grippers 6 do not interfere with each other in the case where the elevator 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 the car 3 become the closest.
  • the rope regulator 10 is formed of a material softer than the material of the outer layer of the steel elevator ropes 5, for example, synthetic resin such as polyethylene or wood. That is, the material used for the rope regulator 10 is a material that does not damage the elevator ropes 5 when touched by the ropes 5.
  • the rope regulator 10 is suspended by a flexible member 17. Both ends of the flexible member 17 are fastened to the rope grippers 6.
  • the rope grippers 6 are in positions near the rope regulator 10, thus they are suitable as locations to which the flexible member 17 is to be fastened.
  • a wire for example, is used; however, other objects may also be used as long as they are capable of supporting the weight of the rope regulator 10 without problems.
  • the elevator ropes 5, which have an end gripped by a plurality of rope grippers 6 arranged in parallel, are passed through through holes 15 that are formed in the rope regulator 10 and maintained at a designated interval. For this reason, even in the case where the suspension sheave 4 becomes close to the rope grippers 6 due to the ascent and descent of the elevator car 3, although the elevator ropes 5 in the vicinity of the rope grippers 6 tend to approach each other, mutual interference of the rope grippers 6 is avoided since the positions of the ropes 5 are maintained because the ropes 5 touch the through holes 15.
  • the elevator ropes 5 are passed with a gap through the rope regulator 10, thus the elevator ropes 5 may rotate in the circumferential direction against the through holes 15. For this reason, even in the case where untwisting of the elevator ropes 5 occurs, no load is applied to the ropes since the elevator ropes 5 are not caught by the rope regulator 10. Accordingly, the durability of the elevator ropes 5 is not damaged.
  • the elevator ropes 5 are movable also in the longitudinal direction of the ropes 5, in the case where the tension of the elevator ropes 5 is to be adjusted at maintenance, it is possible to adjust the tension of each of the elevator ropes 5 without removing the rope regulator 10.
  • the rope regulator 10 is formed of a material softer than the material of the outer layer of the elevator ropes 5, even in the case where the elevator ropes 5 touch the rope regulator 10, it is possible to avoid damage to the elevator ropes 5.
  • Figure 3 is a cross-sectional view illustrating the rope regulator in accordance with the second embodiment of the present invention.
  • a rope regulator 10 is arranged in the vicinity of rope grippers 6 and the rope regulator 10 is suspended by a flexible member 17 in accordance with Figure 1 , as in the first embodiment. Further, both ends of the flexible member 17 are fastened to the rope grippers 6.
  • the rope regulator 10 is formed by assembling two outer plates 11 and an inner plate 12.
  • the rope regulator 10 is formed by assembling two outer plates 11 and an inner plate 12.
  • a material softer than the material of the outer layer of the elevator ropes 5 such as a synthetic resin material such as polyethylene or the like.
