Abstract

<P>PROBLEM TO BE SOLVED: To provide an elevator capable of precluding collision sounds emitted in association with contacting of ropes with one another. <P>SOLUTION: The elevator is composed of a plurality of ropes 1 with the two ends fixed to the upper part of a building 2, an elevator car 3 hung by the ropes 1, and a winch 6 to drive the ropes 1 through a sheave 5, wherein a buffer 11 to prevent the ropes from colliding with one another is attached to each end of the ropes 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an elevator for preventing a collision between ropes that suspend a car.

Recently, a machine room comprising a plurality of ropes whose ends are fixed to the upper part, a ride suspended by the plurality of ropes, and a hoisting machine that drives the plurality of ropes through a sheave. Less elevators are generally used (for example, see Patent Document 1).
JP-A-11-278768 (see paragraph numbers 0005 and 0006)

  However, the elevator has a problem that as the car rises from the lower side to the upper side, the swing of the rope is amplified and changed into vibration, and the ropes come into contact with each other to generate a collision sound.

  The objective of this invention is providing the elevator which can prevent the collision sound accompanying the contact of ropes.

  In order to achieve the above-mentioned object, according to claim 1 of the present invention, a plurality of ropes having both ends fixed to the upper part, a cage suspended by the plurality of ropes, and the plurality of ropes are sheaveed. In an elevator comprising a hoisting machine driven via a cushioning material for preventing collision of ropes is provided at the end of the rope.

  According to a fourth aspect of the present invention, there are a plurality of ropes whose ends are fixed to the upper part, a ride suspended by the plurality of ropes, and a winding for driving the plurality of ropes through a sheave. In an elevator composed of an upper machine, a cylindrical cushioning material is provided on a side of the car via a joint, and the circumference of the rope is covered with the cylindrical cushioning material.

  In the present invention configured as described above, since the shock absorber is provided at the end of the rope to prevent the collision between the ropes, even if the rope vibrates and collides, the shock is alleviated by the shock absorber, and a collision sound is generated. There is no. Moreover, since the circumference | surroundings of a rope are covered with the cylindrical buffer material, a collision does not arise and a collision sound is not generated.

  According to the present invention, even if the rope vibrates and collides, the shock is alleviated by the cushioning material and no collision sound is generated. Moreover, since the circumference | surroundings of a rope are covered with the cylindrical buffer material, it does not produce a collision and does not generate | occur | produce a collision sound.

  Hereinafter, an embodiment of an elevator concerning the present invention is described based on figures.

  FIG. 1 is an explanatory diagram showing the overall configuration of an elevator that is the subject of the present invention, FIG. 2 is a partial side view of an elevator equipped with a cushioning material according to an embodiment of the present invention, and FIG. 3 is another embodiment of the present invention. It is a partial side view of the elevator provided with the buffer material which becomes a form.

  In FIGS. 1 and 2, reference numeral 1 denotes a plurality of ropes whose both ends are fixed to the upper part of the building 2, and a car 3 is suspended from the rope 1 via a pulley 4. A sheave 5 is driven by a hoisting machine 6 fixed below, and the rope 1 is wound around the sheave 5. 7 and 8 are idle pulleys supported by the building 2, and the rope 1 is wound around the idle pulley. A counterweight 9 is supported by a pulley 10, and the rope 1 is wound around the pulley 10. 11 is a cushioning material that is wound around the end of the rope 1 on the side of the car 3, and this cushioning material 11 is composed of a mesh sheet knitted with a fine wire of steel wire, a foamed rubber, a resin sheet or the like. ing.

  Now, when the hoisting machine 6 is driven, the sheave 5 is rotated and the car 3 and the counterweight 9 are moved up and down via the rope 1. When the car 3 moves from below to above, the swaying rope 1 amplifies as the car 3 rises and turns into vibration and collides with the adjacent rope 1 but hits the shock absorber 11 so that the shock is mitigated and noise Is prevented from occurring.

  In addition, as the buffer material 11, the mesh sheet knitted with the fine wire of the steel wire is optimal when considering the strength, the buffer effect, and the like.

  In FIG. 3, reference numeral 12 denotes a cylindrical cushioning material provided on the side of the car 3 via a joint 13. The cylindrical cushioning material 12 covers the periphery of the rope 1.

  Therefore, the rope 1 that is swaying as the car 3 is lifted is covered with the periphery of the rope 1 and hits the cylindrical cushioning material 12 so that the swaying is suppressed and no collision between the ropes 1 occurs. Will not occur.

It is explanatory drawing which shows the whole structure of the elevator used as the object of this invention. It is a partial side view of the elevator provided with the shock absorbing material which becomes one Embodiment of this invention. It is a partial side view of the elevator provided with the shock absorbing material which becomes other embodiment of this invention.
