Abstract

There is provided a mounting tool for an elevator rope tension measurement device, the mounting tool being capable of preventing the rope tension measurement device from interfering with a rope disposed adjacently to a rope that is a measurement target. A mounting tool for an elevator rope tension measurement device includes: a first holding body configured to hold a rope of an elevator; a second holding body configured to hold a rope tension measurement device that measures a tension of the rope; and a connecting body configured to connect the first holding body with the second holding body so as to dispose the rope tension measurement device at a position away from the rope.

Claims (26)

1. A mounting tool for an elevator rope tension measurement device, the mounting tool comprising:

a first holding body configured to hold a rope in a first row of an elevator having a plurality of ropes arranged in the first row and a second row;

a second holding body configured to hold a rope tension measurement device that measures a tension of the rope; and

a connecting body configured to connect the first holding body with the second holding body so as to dispose the rope tension measurement device at a position away from the rope,

wherein the connecting body connects the first holding body with the second holding body such that, in a state where the first holding body holds the rope in the first row, the rope tension measurement device is disposed on a side of the ropes in the second row that is opposite to the ropes in the first row, and

the first holding body holds the rope by a pair of holding parts arranged in a row in a vertical direction, and a product of a distance between positions where the pair of holding parts hold the rope and a holding force of an upper holding part for holding the rope is greater than a rotational moment by a dead load of the rope tension measurement device.

2. The mounting tool for an elevator rope tension measurement device according to claim 1 , wherein the second holding body holds the rope tension measurement device such that a direction in which a vibration is detected by the rope tension measurement device matches a direction of a vibration of the rope.

3. The mounting tool for an elevator rope tension measurement device according to claim 1 , comprising a first fall preventing body having one side connected to the connecting body and having another side mounted, at a position higher than the rope tension measurement device, to an adjacent rope other than a rope on which a measurement is to be made or to a structural body of an elevator.

4. The mounting tool for an elevator rope tension measurement device according to claim 1 , comprising a second fall preventing body having one side connected to the connecting body and having another side mounted to the rope tension measurement device.

5. The mounting tool for an elevator rope tension measurement device according to claim 1 , wherein the first holding body is a clip having a curvature conforming to an outer diameter of the rope.

6. The mounting tool for an elevator rope tension measurement device according to claim 5 , wherein the first holding body is the clip having a plurality of curvatures respectively conforming to outer diameters of a plurality of ropes.

7. The mounting tool for an elevator rope tension measurement device according to claim 1 , wherein the connecting body has a natural frequency greater than a frequency of the rope.

8. The mounting tool for an elevator rope tension measurement device according to claim 1 , wherein the connecting body has one side connected to one side of the second holding body, and is orthogonal to the second holding body.

9. The mounting tool for an elevator rope tension measurement device according to claim 1 , wherein the second holding body includes

a first holding part configured to hold the rope tension measurement device from a side, and

a second holding part configured to generate a load in the horizontal direction so as to apply a force of holding the rope tension measurement device to the first holding part.

10. A mounting tool for an elevator rope tension measurement device, the mounting tool comprising:

a first holding body configured to hold a rope of an elevator;

a second holding body configured to hold a rope tension measurement device that measures a tension of the rope; and

a connecting body configured to connect the first holding body with the second holding body so as to dispose the rope tension measurement device at a position away from the rope,

wherein the first holding body includes an uneven-shaped tip that fits to unevenness on an outer periphery of the rope, the uneven-shaped tip including an edge having alternating long and short portions, and the long portions are longer than the short portions in a direction of an outer surface of the uneven-shaped tip.

11. The mounting tool for an elevator rope tension measurement device according to claim 10 , wherein the connecting body has a natural frequency higher than a frequency of the rope.

12. The mounting tool for an elevator rope tension measurement device according to claim 10 , wherein the connecting body has one side connected to one side of the second holding body, and is orthogonal to the second holding body.

13. The mounting tool for an elevator rope tension measurement device according to claim 10 , wherein the second holding body includes

a first holding part configured to hold the rope tension measurement device from a side, and

a second holding part configured to generate a load in the horizontal direction so as to apply a force of holding the rope tension measurement device to the first holding part.
