DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a governor rope tensioning wheel adjusting device.

[0002]

2. Description of the Related Art Generally, a governor rope elongates after a long period of time. For this purpose, a governor rope tensioning wheel and a governor rope tensioning weight are provided so that the governor rope tension is always constant. As a structure for keeping the governor rope tension constant, as shown in FIGS. 5 and 6, a support 101 fixed to a guide rail 100 is used.
A bracket 102 rotatably attached to the support 101; a governor rope tensioning wheel 103 rotatably attached to the center of the bracket 102; and a weight 104 for a governor rope tensioning 105 fixed to the free end of the bracket 102. A governor rope tensioning wheel adjusting device is known.

[0003]

In the conventional governor rope tensioning wheel adjusting device, the bracket 10 is normally used.
6 is installed horizontally, the governor rope 105 shrinks in a rainy season.
As shown in FIG. 1, a phenomenon that the weight 104 comes into contact with the governor rope 105 has occurred. Governor rope 105
However, when the governor rope 105 moves, the problem that contact noise occurs between the governor rope 105 and the weight 104 cannot be avoided.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a governor rope tensioning wheel adjusting device in which a weight does not contact the governor rope even if the governor rope shrinks.

[0005]

An object of the present invention is to provide a support fixed to a guide rail, a bracket rotatably mounted on the support, and a governor rope tensioning wheel rotatably mounted on the center of the bracket. And a governor rope tensioning wheel adjustment device having a governor rope tensioning weight fixed to the free end of the bracket, wherein the weight is a first weight member attached to the free end of the bracket, and the first weight member is And a second weight member attached to the first weight member using an attachment member so that a gap is formed between the bracket and the second weight member. The gap is set to be larger than the diameter of the governor rope, and the bracket rotates upward. A configuration in which the first weight member and the second weight member are arranged so that the governor rope can be fitted between the gaps. In Rukoto, it is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, the elevator has a traction machine and a governor 3 installed in a machine room, and a car 4 and guide rails 5 installed in a hoistway. In the hoistway, a governor rope 6, a governor rope tensioning wheel adjusting device 7, a buffer 8, a counterweight 10 attached to a main rope 9, and the like are provided.

The governor rope tensioning wheel adjusting device 7 includes a support 12 fixed to the guide rail 5 using a rail clip 11, a bracket 13 rotatably attached to the support 12, and a central portion of the bracket 13. A governor rope tensioning wheel 14 and a bracket 13 which are rotatably mounted.
And a weight 15 fixed to the free end of

As shown in FIGS. 2 and 3, a gap G is formed between the plate-shaped first weight member 16 attached to the free end 13a of the bracket 13 and the first weight member 16, as shown in FIGS. The plate-shaped second weight member 1 attached to the first weight member 16 using the attachment member 17
It consists of eight. The gap G is set to be larger than the outer diameter of the governor rope 6.

The bracket 13 is attached to the support 12 so as to be rotatable by a support 19.
The governor rope tensioning wheel 14 is rotatably attached to the bracket 13 by a rotating shaft 20. As shown in FIG. 4, the first member 16 and the second weight member 18 are free ends 13 a of the bracket 13 so that the governor rope 6 fits between the gaps G when the bracket 13 rotates upward. It is arranged in. Bracket 1 on support
3 is a steel plate.

In the above configuration, when the governor rope 6 is contracted in a rainy season and the governor rope tensioning wheel 14 is lifted upward, the bracket 13 rotates upward around the support 19 and the weight 15 becomes It approaches the governor rope 6. However, as shown in FIG. 4, the governor rope 6 enters the gap G between the first weight member 16 and the second weight member 18, and the first weight member 16 and the second weight constituting the weight 15. There is no contact with the member 18. Therefore, the governor rope 6 has the weight 15
And no contact noise due to the weight 15 is generated.

[0012]

As described above, according to the present invention, even when the governor rope shrinks, the weight does not come into contact with the governor rope, so that the governor rope can be prevented from being damaged and the contact noise of the weight can be prevented. A governor rope tensioner adjuster was obtained.
