Abstract

PURPOSE:To prevent the whole governor rope from shaking by disposing a pair of elastic rope bracing members provided with a curved surface shaped stopper piece which prevents the rope from popping out at its edge part, facing each other so that a governor rope on the moving body side may be put between in a supporting body which is installed at an elevator passage side wall. CONSTITUTION:Plural supporting members 3 are installed in a guide rail 2 which is laid on an elevator passage side wall in a horizontal direction. A semicircle rope bracing material 16 is installed at the suporting member 3 so as to surround a not moving body side governor rope 5. Besides, a rope bracing member 14 provided with a rope guide plate 13 vetrically with a stopper piece 16 which prevents the rope from popping out on its edge part is installed at the central part near the guide rail 2 through a long hole 12 so that the governor rope 10 on the moving body side may be put between. Therefore, the moving body side governor rope 10 is surrounded by the supporting body 3 and the bracing member 14 from three directions, so it is thus possible to prevent the rope from shaking.

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope steadying device for preventing the governor rope of an elevator from swinging.

0003

[Prior Art] When the speed of an elevator car exceeds the rated speed due to mechanical or electrical failure or overloading, a speed governor in the machine room detects this and connects the car to the car. The car comes to an emergency stop by activating the car's emergency stop device via the governor rope (governor rope), which is stretched between the speed governor and the rope tensioning wheel at the bottom of the hoistway. ing.

By the way, the longer the governor rope is, that is, if a strong wind or earthquake occurs while the car is running in a high-rise building, etc., the governor rope may shake and get caught on equipment in the hoistway or the car, affecting the elevator movement of the car. .

For this reason, conventionally, as shown in FIGS. 5 and 6, a governor rope 5 (an emergency stop device operating lever) on the non-moving body side is attached to a support member 3 horizontally fixed at arbitrary intervals to a guide rail 2 in an elevator hoistway 1. Attach the rope steadying material 6 to the fixing metal fitting 7 to prevent the swinging of the rope on the side where the
It is installed by This suppresses the amplitude of the swing of the governor rope 5 on the non-moving body side, so that it does not get caught in equipment in the hoistway, the car 8, etc.

On the other hand, a moving body side governor rope 10 connected to the car 8 is provided with an emergency stop device operating lever 11. Therefore, if a rope steadying material is attached, when the car 8 goes up and down, the governor rope 1 on the moving body side
0 and the emergency stop device operating lever 11 interfere with the rope steadying material. In the end, it is not possible to attach the steady rest of the current configuration to the rope on the side of the moving body.

Therefore, as a countermeasure, an electromagnet was used to create a steady rest that opens and closes when the operating lever passes.
5404) and one using a protective material with an opening (Japanese Utility Model Publication No. 49-7807), but these had problems such as having a complicated structure and not being easy to adjust. For this reason, there is no effective means for preventing the governor rope on the moving object side from swinging, and the risk of the rope getting caught on equipment in the hoistway or on the car remains unresolved.

[0008]

[Problems to be Solved by the Invention] As mentioned above, the governor rope on the side of the non-moving object of the elevator is prevented from swinging by the rope rest, but the governor rope on the side of the moving object cannot be prevented from shaking, so it is difficult to raise or lower the car. There is a risk of it shaking inside and getting caught in hoistway equipment, cars, etc.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a rope steadying device that is effective in suppressing the swinging of a governor rope on the side of a moving object.

[Configuration of the invention]

[0011]

[Means for Solving the Problems] For the above-mentioned purpose, the present invention is a steady rest device for a governor rope on a moving body side, and is provided on support members installed horizontally at arbitrary intervals along a guide rail laid in a hoistway. Two rope steady rest members each having a rope guide plate vertically attached thereto are fixed to face each other on the left and right sides, and the moving body side governor rope is surrounded from three sides by the support member and the rope steady rest members. A governor rope protrusion prevention piece having a curved surface is attached to the opposing tip of the rope guide plate.

0012

[Function] When the moving body side governor rope swings, it is caught by the rope jumping-out prevention piece and prevented from swinging, so the governor rope does not jump out, and when the operating lever passes through the steady rest, the elastic body prevention piece There is no problem because it is interference.

[0013]

EXAMPLE The present invention will be explained based on the example shown in FIGS. 1 and 2.

A plurality of support members 3 are horizontally attached at intervals to a guide rail 2 laid on a side wall of an elevator hoistway 1. A non-moving body side governor rope 5 is surrounded by a support member 3, and a semicircular rope steadying member 6 is attached with a fixing fitting 7.

Next, two elongated holes 12 for attachment are made in the center of the support member 3 near the guide rail 2, and a rope guide plate 13 with a rope protrusion prevention piece 16 attached to the tip is vertically provided. The rope steadying members 14 are fixed to the elongated hole 12 with the fixing fittings 15 with the left and right sides facing each other. With this configuration, the supporting member 3 and the left and right rope steadying members 14 surround the moving body side governor rope 10 from three sides.

The governor rope protrusion prevention piece 16 attached to the tip of the rope guide plate 13 has a curved surface, and is provided facing left and right with the emergency device operating lever 11 in between.
1 is made easier to pass through. The rope guide plate 13 is made elastic so that the rope attachment part 17 can easily pass through it.

In the above structure, the mounting position of the rope steadying member 14 is shifted from side to side using the elongated hole 12 provided in the support member 3, and the position of the emergency stop device operating lever 11 is moved to the left and right governor rope protrusion prevention pieces 16. It is possible to adjust the

Furthermore, when the moving body side governor rope 10 is shaken, it gets caught on the governor rope protrusion prevention piece 16, so that
The governor rope 10 does not fly out and interfere with other ropes and equipment.

In this way, it becomes possible to attach the moving body side rope steadying member 14 and the non-moving body side rope steadying member 6 to the support member 3, and it is possible to prevent the governor ropes 5, 10 from rolling.

Other embodiments of the present invention are shown in FIGS. 3 and 4.
In this example, the rope protrusion prevention piece 16 attached to the tip of the rope guide plate 13 is made of a shape-deformable material such as rubber, and normally the left and right rope protrusion prevention pieces 18 are brought into close contact with each other in the closed state. Then, when the emergency stop device operating lever 11 passes, it may be forcibly pushed open and passed. In this way, the steady rest of the moving body side governor rope 10 can be further ensured.

[0021]

[Effects of the Invention] As described above, by providing a steady rest for the governor rope on the moving body side of the elevator according to the present invention,
Together with the steady rest of the governor rope on the non-moving object side, this prevents the entire governor rope from shaking, improving the safety of the elevator.
