JP 2008-13302 A

  The governor rope steady-state device described in Patent Literature 1 has a rotating body that comes into contact with a pulling lever. For this reason, the noise caused by the rotating sound of the rotating body and the contact resistance between the lifting lever and the rotating body are large, the rotating body itself requires a large space in the hoistway, and the other length of the elevator is added to the rotating body itself. There were problems such as the scale being easily caught.

  An object of the present invention is to provide a governor rope steady rest apparatus having a compact and simple configuration, and having a small sound and resistance when coming into contact with a pulling lever, and an elevator equipped with the governor rope steady rest apparatus.

  The governor rope steadying device of the present invention is a device that prevents the governor rope from swinging by passing the governor rope of the elevator inward, and includes a steadying portion and a hinge formed of an elastic body, and is connected to the governor rope. The lifting lever is in contact with the hinge as the elevator car moves up and down.

  ADVANTAGE OF THE INVENTION According to this invention, the governor rope steadying apparatus of an elevator is made into a compact and simple structure, and the sound and resistance at the time of contacting with a raising lever can be reduced.

It is a longitudinal cross-sectional view of the hoistway which shows the whole structure of the elevator of this invention. It is a top view which shows arrangement | positioning of the governor rope steady rest apparatus of Example 1. FIG. It is a top view which shows the governor rope steady rest apparatus of Example 1. FIG. It is a front view of the governor rope steadying apparatus of FIG. It is a front view which shows the governor rope steady rest apparatus of Example 2 partially.

  The governor rope steady rest device of the present invention has a configuration in which a hinge formed of an elastic body is attached to a lever passage portion which is a gap between the steady rest portions. The hinge is openable. When the lifting lever connected to the governor rope comes into contact with the hinge as the elevator car moves up and down, the hinge opens and closes.

  FIG. 1 is a longitudinal sectional view of a hoistway showing the overall structure of an elevator according to the present invention.

  As shown in the figure, the elevator has a structure in which the car 5 is moved up and down by connecting the car 5 and the counterweight 8 with a rope 21 and operating a hoisting machine 22 installed in the machine room 1. An emergency stop device 9 is attached to the lower part of the car 5. The emergency stop device 9 has a lifting lever 6.

  The machine room 1 is provided with a governor 2 (speed governor). A tension wheel 4 is installed in the lower part of the hoistway 3. A governor rope 7 is stretched endlessly between the governor 2 and the tension wheel 4. The governor rope 7 is connected to the lifting lever 6 at one position on one side. Of the governor rope 7, the portion on the lifting lever 6 side is called a moving object-side governor rope 7 a, and the portion opposite to the lifting lever 6 is called a non-moving object-side governor rope 7 b.

  In the embodiment described later, the lifting lever 6 passes through the inside of the governor rope steadying device.

  Examples will be described below.

  FIG. 2 is a plan view showing the arrangement of the governor rope steady rest device of the present embodiment.

  FIG. 3 is a plan view showing the governor rope steady rest device of the present embodiment.

  FIG. 4 is a front view of the governor rope steadying device of FIG.

  As shown in FIG. 2, the car 16 is moved up and down by the guide rail 17 so as not to swing in the horizontal direction. The guide rail 17 is supported by the bracket 12. The bracket 12 is fixed to a building (wall surface of the hoistway). The governor rope 11 is disposed so as to pass through a region surrounded by the moving object-side governor rope steady rest 13 (also simply referred to as a “rest portion”) and a region surrounded by the non-moving object-side governor rope steady rest 18. This is to prevent the governor rope 11 from swinging and being caught by other equipment.

  In addition, a raising lever 15 is attached to the car 16. The lifting lever 15 passes through the moving object side governor rope steady rest 13 by raising and lowering the car 16. The moving object side governor rope steady rest 13 and the non-moving object side governor rope steady rest 18 are supported by the bracket 12.

  As shown in FIG. 3, the moving object side governor rope steady rest 13 has two symmetrical plate members. Each of the two plate members is provided with a hinge 14. The hinge 14 is an openable and closable leaf spring, and is deformed when the lifting lever 15 contacts, so that the lifting lever 15 can easily pass therethrough.

  The governor rope steady rest device of the present invention includes a moving object side governor rope steady rest 13 and a hinge 14.

  When the lifting lever 15 does not pass, the hinge 14 is closed, so the periphery of the governor rope 11 including the moving object side governor rope steady rest 13 is closed, and the governor rope 11 is not detached from the moving object side governor rope steady rest 13 and the hinge 14. Absent.

  As shown in FIG. 4, as the car is raised and lowered, the lifting lever 15 is also raised and lowered. FIG. 4 shows a state in which the lifting lever 15 has reached above the hinge 14.

  When the lifting lever 15 is lifted, it passes between the moving object side governor rope steady rests 13 while pushing up the hinge 14. On the other hand, when the lifting lever 15 is lowered, it passes between the moving object side governor rope steady rests 13 while pushing down the hinge 14. In any case, the hinge 14 is an elastic body, and opens due to the elasticity while interfering with the pulling lever 15. For this reason, movement of a cage | basket | car, governor rope 11, etc. is not inhibited.

  On the other hand, the non-moving object-side governor rope steady rest 18 is composed of one plate material and does not have a hinge because the lifting lever 15 does not pass therethrough.

  The moving body side governor rope steady rest 13 is the same size as the non-moving body side governor rope steady rest 18 and has a compact and simple configuration. For this reason, no special parts other than the hinge are required, the steady swing of the governor rope 11 can be ensured, and the lifting lever 15 can be easily passed.

  Further, the moving object side governor rope steady rest 13 generates a contact sound when the pulling lever 15 comes into contact with the hinge 14, but does not generate a sound like a rotating sound of the rotating body.

  Since the hinge 14 has a simple opening / closing structure, there is no contact resistance between the hinge 14 and the lifting lever 15, but there is no resistance around the reversal of the rotating body due to the upside down movement of the car 16. For this reason, resistance can be made extremely small.

  FIG. 5 is a front view partially showing the governor rope steadying device of the present embodiment.

  In this figure, the moving body side governor rope steady rest 13 has two symmetrical plate materials. One of the two plate members is provided with a hinge 54. The hinge 54 is an openable and closable leaf spring, and is deformed when the lifting lever contacts, so that the lifting lever can easily pass therethrough.

  Compared with the first embodiment, the number of the hinges 54 is only one, so that the configuration is further simplified and the manufacture is facilitated.

  In the above-described embodiment, the moving object-side governor rope steady rest is composed of two plate materials, but the moving object-side governor rope steady rest of the present invention is not limited to this, and one plate material is used. An anti-sway part having a gap to which a hinge is attached may be formed by bending.

  In addition, this invention is not limited to the Example mentioned above, A various modification is included. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
