Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a tape guide for a tape stretched along the ascending and descending direction of a hoistway for use in driving an elevator floor controller.

[Background of the idea]

In a normal elevator, as shown in Fig. 1, an elevator car 1 is connected to one end of a main rope 5 wound around a steel wheel 2 and a deflection wheel 3 of a hoisting machine, and connected to the other end of the main rope 5. It is suspended in a hanging style with a counterweight 4. A floor controller 6 is installed in parallel on the machine room floor 7 where the hoisting machine is installed, and is suspended between upper and lower pulleys 9 and 10 provided between the hoistway floor 8 and the hoistway floor 8. With the floor controller tape 11, the car 1
It is driven as the elevator goes up and down and is used to detect the position to control the elevator. The tape 11 is made of metal and is provided with claws 21 on the upper and lower pulleys 9 and 10 as shown in FIG. 2 to ensure that no slipping occurs when the pulley 9 on the floor controller 6 side is driven. It engages with a protrusion (not shown).

By the way, as the height of the building increases and the elevator travel becomes longer, the width of sway of the floor controller tape 11 increases due to the lateral vibration of the building and the vertical movement of the elevator. It may come into contact with various equipment and cause damage. Therefore, as shown in Figure 1,
A tape guide 12 for guiding the floor controller tape 11 is arranged at an appropriate location in the hoistway.

However, as shown in Figure 3, conventional tape guides are made of materials such as nylon and have a round hole 31 in the center.
Since it has a structure that guides the tape 11, the inner diameter of the round hole 31 wears out due to the sliding of the tape 11, and when replacing it, it is necessary to remove the long tape 11, which requires a lot of effort. It requires effort.

[Purpose of invention]

The present invention has been devised in view of the above points, and its purpose is to provide a reliable elevator floor controller tape guide that is easy to replace and can guide the tape smoothly.

[Summary of the idea]

In order to achieve the above object, the present invention forms the guide hole of the tape guide in a round shape, and configures the tape guide to be divisible so that the guide hole is divided into two, and the guide hole The dividing portion is formed at a position different from the widthwise extension of the floor controller tape.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIG. The tape guide 12 according to the embodiment of the present invention, which is placed at an appropriate location in the hoistway, is made of a material such as nylon so as not to generate noise even when it slides into contact with the floor controller tape 11, and has a semicircular shape divided into two parts. Guides 12A and 1 with shaped holes
2B are integrated with a through bolt 41 to form a round hole 31 in the center. That is, the tape 11 is guided by both widthwise ends of the tape 11 and the inner wall of the round hole 31. In addition, here guide 12
The reason why the guide hole is a round hole is because the tape 11 has a characteristic of not only constantly swinging but also trying to rotate. In addition, as shown in FIG. 2, the tape 11 is provided with a claw 21 for driving purposes, so that even if the guide 12 is worn out, the claw 21 will not be caught and damaged. . Furthermore, the dividing surface 42 of the guide 12 is also formed at a position 90 degrees different from the extension of the tape 11 in the width direction, so that the widthwise end of the tape 11 is not caught on the dividing surface 42 to ensure smooth guidance. I try to do it.

As explained above, according to one embodiment of the present invention, even if the tape guide 12 is worn out due to contact sliding of the tape 11, the guide 12 can be easily replaced by removing the through bolt 41. I can do it. Further, since the guide 12 is made of nylon or the like and there is no split surface in the round hole 31 corresponding to the end in the tape width direction, quiet, smooth and reliable tape guidance can be performed.

FIG. 5 shows another embodiment of the present invention, which differs from FIG. 4 in that a step 52 is provided on the mating surface (dividing surface) 51 of the guides 12A and 12B. In this embodiment, by combining the steps 52, it is easy to align the semicircular holes of the guides 12A and 12B. In addition, in the case of FIG. 4, since the material is nylon or the like, the mating surface (dividing surface) 42 tends to be deformed as shown by the chain line (exaggerated), and as a result, the tape 11 is and 1
There is a risk that it will get caught in the gap 43 of the mating surface (divided surface) of 2B, but in the case of FIG.
Therefore, the possibility that the tape 11 gets caught on the mating surface (dividing surface) of the guide 12 is very small.

[Effect of idea]

As detailed above, according to the present invention, the tape guide has a split structure, and the split portion is formed at a position different from the tape width direction, so that the tape guide can be easily replaced, and the tape guide can be easily removed when the building is swaying. It is possible to obtain a reliable tape guide that effectively prevents lateral wobbling and provides smooth guidance.
