Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator rope detent tool, and more particularly to an elevator rope detent tool suitable for elevators with 2: 1 roping.

[0002]

[Prior Art]

 In the case of a 2: 1 roping elevator, as shown, for example, in Japanese Utility Model Publication No. 57-49872, each of the car and the counterweight is connected by a hoisting rope via a pulley attached to the upper part. The end of the hoisting rope is a machine room at the top of the building, and is fixed to the hoisting plate via thimble rods and tension adjusting springs.

Conventionally, tension adjustment of a rope for lifting an elevator has been performed by rotating a lock nut attached to a thimble rod with a spanner and expanding and contracting a tension adjustment spring. However, it is necessary to fix the thimble rod because the thimble rod rotates together when the lock nut is turned by the spanner. For this fixing method, for example, one person holds the thimble rod by inserting it into the thimble rod from the top of the car and holding it, or by drilling or slitting the upper end of the thimble rod and using these holes and slits. There is a method of holding the thimble rod using.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technique, in the former method of using the detent rod, there are two methods: an operator holding the thimble rod by the detent rod on the car and an operator performing the tension adjustment work in the machine room. There is a problem of requiring human workers. Also, with the latter method of processing thimble rods, it is difficult to carry out the above-mentioned processing locally on existing elevators, and it is costly to carry out processing before factory shipment. There was a problem that I could not do it.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to enable the tension of the hoisting rope to be adjusted by one person without requiring special processing of the thimble rod. It is to provide a rotation stop tool for elevator ropes.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the present invention provides an elevator rope detent tool for adjusting the tension of a hoisting rope in which a terminal is attached to a hanging plate through a thimble rod. Of the thimble rod, and an engaging portion that engages with another thimble rod.

[0007]

[Action]

 Since the present invention is configured as described above, when performing the tension adjustment work of the elevator rope, one thimble rod of the thimble rod is held by the holding portion of the rotation stopping tool, and the engaging portion of the thimble rod is held by another thimble rod. The rotation of the thimble rod is suppressed by engaging with the rod, and the tension is adjusted in this state. As a result, the tension adjustment work can be performed without requiring special processing such as holes and slits for the anti-rotation tool in the thimble rod as in the conventional case. Further, it is possible to perform the tension adjustment work by one person without requiring an operator to control the rotation of the simbu rod.

【Example】

 Hereinafter, an embodiment of an anti-rotation tool for an elevator rope according to the present invention will be described with reference to the drawings. 1 is a front view showing an embodiment of an elevator rope detent tool of the present invention, and FIG. 2 is a perspective view showing a usage state of the detent tool of FIG.

As shown in FIG. 2, the elevator according to the present embodiment is such that the terminals are inserted into the hoisting ropes 3 a and 3 b having the ends attached to the hanging plate 1 via the thimble rods 2 a and 2 b and the thimble rods 2 a and 2 b. Tension adjusting springs 4a and 4b, lock nuts 5a and 5b screwed onto the upper portions of the threaded thimble rods 2a and 2b, and split pins 6a and 6b attached to the upper ends of the thimble rods 2a and 2b. have.

As shown in FIG. 1, the elevator rope detent tool 10 according to the present embodiment has a holding portion that holds one of the thimble rods 2a and 2b, that is, the thimble rod 2a to be adjusted. 10a, an engaging portion 10b that engages with another thimble rod 2b, a cushioning material 10c that is attached to the engaging portion 10b and that prevents the threads of the thimble rod 2b from being crushed, and the anti-rotation tool 10 is thimble rod. It is provided with a split nut 10d that is fixed to 2a and can be moved forward and backward, and a handle 10e that is gripped when the split nut 10d is moved forward and backward.

In this embodiment, when the tension of the hoisting rope 3a is adjusted, the thimble rod 2a to be adjusted by the holding portion 10a is attached to the split pin 6a provided at the upper end of the thimble rod 2a. The position is held according to the position, and the engaging portion 10b is engaged with another thimble rod 2b. Then, the handle 10e is turned to move the split nut 10d forward, and the split pin 6a is fixed by sandwiching the split pin 6a with the holding portion 10a and the split nut 10d. At this time, the cushioning material 10c is applied to the thimble rod 2b so as not to crush the thread of the thimble rod 2b. In this way, the anti-rotation tool 10 is fixed to suppress the rotation of the thimble rod 2a so that the thimble rod 2a does not rotate together with the lock nut 5a, and then the lock nut 5a is turned by the wrench 7 and screwed. The tension adjusting spring 4a is moved forward and backward to expand and contract to adjust the tension of the lifting rope 3a. Also, follow the same procedure to adjust the tension of other lifting ropes.

FIG. 3 is a perspective view showing another embodiment of the rotation stopping tool for an elevator rope according to the present invention.

As shown in FIG. 3, a detent tool 20 according to another embodiment is a nut 20b having a through hole 20a into which the split pin 6a is inserted, which is screwed to the upper end of the thimble rod 2a, the shimble rod 2a, and the nut 20b. One of the 2b, that is, the holding portion 20c that holds the thimble rod 2a to be adjusted, the engaging portion 20d that engages with the other thimble rod 2b, and the detent tool 20 that contacts the nut 20b. A supporting metal fitting 20e for supporting the supporting metal fitting 20e and a screw 20f for fixing the supporting metal fitting 20e to the anti-rotation tool 20 are provided. The other reference numerals are the same as those in FIG. 1 and FIG.

In another embodiment, when adjusting the tension of the hoisting rope 3a, the split pin 6a of the thimble rod 2a is removed and the nut 20b is screwed to the split pin hole of the thimble rod 2a. It is aligned with the through hole 20a, and then the split pin 6a is inserted. The holding portion 20c holds the nut 20b to hold the thimble rod 2a, and the engaging portion 20d is engaged with another thimble rod 2b. Next, the support metal fitting 20e is brought into contact with the nut 20b and fixed to the rotation stopping tool 20 with the screw 20f, and the rotation stopping tool 20 is supported. In this way, the rotation stopping tool 10 suppresses the rotation of the thimble rod 2a so that the thimble rod 2a does not rotate together with the lock nut 5a, and the tension adjustment work is performed in the same procedure as above. ing.

In the embodiment configured as described above, the tension adjustment work of the hoisting ropes 3a, 3b is performed without requiring special processing such as holes and slits for the anti-rotation tool in the thimble rod as in the prior art. be able to. Further, it is possible to perform the tension adjustment work of the lifting ropes 3a and 3b by one person without requiring an operator to suppress the rotation of the simbu rods 2a and 2b.

[0016]

[Effect of the device]

 Since the present invention is configured as described above, since the thimble rod needs special processing such as holes and slits for the rotation stopping tool as in the conventional case, it can be used for lifting without significantly increasing the cost. Rope tension adjustment work can be performed. Further, there is no need for a worker to control the rotation of the simbu rod, and the tension adjustment work of the hoisting rope can be performed by one person, which can improve the efficiency of the work. is there.
