Problems solved by technology

Therefore, there is a problem that when the tension of one of the reference ropes is weak, when the other rope is stretched, the two will move together, so that the correct tension cannot be measured.
[0005] Furthermore, there is also the following problem: when reading the measurement results, it is necessary to maintain the state of pulling the rope by hand, and it requires a considerable amount of labor when the number of ropes is large.

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0019] figure 1 It is a plan view of the rope tension measuring device according to one embodiment of the present invention seen from above. figure 2 is a side view of the measurement device viewed from the side, image 3 It is a front view of the measuring device viewed from the front. The rope tension measuring device of the present invention is mainly used to measure the tension of a plurality of ropes (main hoisting ropes) supporting an elevator car.

[0020] Such as Figure 1 to Figure 3 As shown, the rope tension measuring device 10 of the present embodiment includes a rectangular and thin device main body 11 . A hook member 12 for hooking a rope to be measured is attached to a front end portion of the device main body 11 . A sensor 13 for measuring the tension of the rope via the hook member 12 is incorporated in the device main body 11 .

[0021] The sens...

Abstract

The invention relates to a rope tension measuring device. When a hook component (12) arranged on the front end part of a device main body (11) is hung on a rope to be measured, the end part of one of a pair of arms (18a, 18b) formed on the front end part of a Y-shaped main body supporting component (17) is pressed on the rope, and the end part of the other arm is pulled to body to rotate, thus measuring tension of the rope by a sensor (13) through the hook component (12). Thereby, tension of each rope is accurately and simply measured without depending on tensioning other ropes.

Description

technical field [0001] The present invention relates to a rope tension measuring device used for measuring the tension of a plurality of ropes (main hoisting ropes) supporting an elevator car together with a counterweight, for example. Background technique [0002] The car of the elevator is supported by a plurality of ropes (traction ropes), driven by the traction machine, through these ropes, together with the balance counterweight, the lifting action is performed in the hoistway. Here, in order to make the car go up and down stably, it is necessary to uniformly adjust the tension of each rope in advance. [0003] As an instrument used in this adjustment work, for example, a tension measuring device disclosed in Japanese Unexamined Patent Application Publication No. 2005-345164 is known. This tension measurement device includes: a tension measurement unit that moves any one of the ropes to measure the force required for its movement; The position is used as a reference t...
