Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a rope removing device for an elevator governor.

[Conventional technology]

Generally, in an elevator, the traveling speed of a car is controlled via a loop-shaped rope by a speed governor provided in a machine room above the hoistway. Further, both ends of this rope are fastened to a car, an upper portion of the rope is wound around a pulley of the governor, and a lower portion of the loop is wound around a tension pulley arranged near the pit at the bottom of the hoistway. When conducting a performance test of the governor, remove the rope from the pulley of the governor, and drive the pulley at a specified number of revolutions with a rotating device to check the operating condition of the governor. ing.

Conventionally, for removing the rope of this speed governor, for example, as shown in JP-A-61-263583, in the machine room,
It has been proposed to provide a gripping device for gripping the hanging portion of the two speed governor ropes on the side separated from the car. Then, hold the hanging part of the rope away from the car with this gripping device and move the car upward to loosen the rope between the car and the gripping device, and remove the rope from the pulley of the governor. It has become.

[Problems to be solved by the device]

By the way, in the conventional rope removing device as described above,
It is necessary to release the brake that holds the car hoisting machine in a stopped state and move the car upward due to the weight difference between the car and the counterweight, but this work requires a brake release device. Not only that, but there was the problem that opening the brake was dangerous. Especially for high-speed elevators, the hoisting machine and the hoisting machine brake will be large, and a large brake release device will be required to accommodate this, making it difficult to move the car upward. There was also the problem of being there.

The present invention has been made in view of the actual situation in the related art as described above, and an object thereof is to provide a rope detaching device capable of detaching a rope from a pulley of a speed governor without requiring movement of a car. is there.

[Means for Solving the Problems]

In order to achieve this object, the present invention wraps around a pulley of a speed governor provided in a machine room above the hoistway and hangs down from both sides of the pulley into the hoistway. In the rope removing device used when removing the rope from which the rope is coupled from the pulley, which is installed at any time, holds one hanging portion of the rope, and holds the position of the rope, and A pull-up device comprising a lever having a fastener for holding the other hanging portion of the rope and a support body for rotatably supporting one end side of the lever. is there.

[Action]

Since the present invention is configured as described above, the gripping device is arranged near the hanging portion on the car side of the rope wound around the pulley of the speed governor, and the pulling device is arranged near the other hanging portion. Holds the hanging portion of the rope on the car side, and pulls up the other hanging portion of the rope by the pulling device to loosen the rope between the holding device and the pulling device. This allows the rope to be removed from the pulley of the governor without the need to move the car.

〔Example〕

The rope removing device of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the rope removing device of the present invention, FIG. 2 is a side view showing a portion of a gripping device provided in the rope removing device of FIG. 1, and FIG. FIG. 4 is a side view showing a portion of a pulling device provided in the rope removing device, and FIG. 4 is a vertical cross-sectional view showing a main configuration of an elevator including the rope removing device of FIG.

In FIG. 4, 11 is a hoistway, 12 is a pit at the bottom of the hoistway 11, 13 is a machine room formed on the top of the hoistway 11, 13a is the floor of the machine room 13, and 14 is the inside of the machine room 13. It is a car that is driven by a hoist and moves up and down in the hoistway 11. Further, 1 is a speed governor installed in the machine room 13, 2 is a pulley mounted on the speed governor 1, 3 is a rope whose upper part is wound around the pulley 2, and 3a is a rope 3 hanging from the car 14 side. Part 3b is the other hanging part of the rope 3 which is separated from the car 14, 4 is a tension pulley which is provided near the pit 12, and the lower part of the rope 4 engages, and 5 is a fastener which connects both ends of the rope 3 and the car 14. In the device, the rope 3 has both ends connected to each other, and is formed in a loop shape between the pulley 2 and the tension pulley 4.
A gripping device 7 is provided in the machine room 13 for gripping the hanging portion 3a of the rope 3 on the car 5 side, and 8 is arranged on the opposite side of the gripping device 7 with the pulley 2 interposed therebetween. It is a pulling device that pulls up the hanging portion 3b.

As shown in FIG. 2, the gripping device 7 is composed of a support 7a fixed to the floor 13a and a fastener 7b fastened to the support 7a. The hanging portion 3a of the rope 3 on the car 14 side is gripped between the metal fittings 7b. On the other hand, as shown in FIG. 3, the pulling device 8 includes a support 8a fixed to the floor 13a, a vertically rotatable lever portion 8b provided at one end on the support 8a, and a lever 8b. It is fastened to the portion 8b and comprises a fastener 8c that holds the other hanging portion 3b of the rope 3.

In this embodiment, at the time of removing the rope, first, the hanging portion 3a of the rope 3 on the side of the car 14 is sandwiched between the support 7a of the gripping device 7 and the fastener 7b, and the fastener 7b is supported. By connecting it to 7a, the hanging part 3a on the car 14 side
To hold. Next, as shown in FIG. 3, the other hanging portion 3b of the rope 3 is sandwiched between the lever portion 8b and the metal fitting 8c which are arranged horizontally, and the metal fitting 8c is fastened to the lever portion 8b. , One end of the lever portion 8b is raised, and the other hanging portion 3b of the rope 3 is pulled up. At this time, as the tension pulley 4 rises, the upper portion of the rope 3 loosens between the gripping device 7 and the pulling device 8, and the portion where this loosening has occurred is removed from the pulley 2.

In the embodiment configured as described above, the rope 3 is pulled up by the pulling device 8 to loosen it without moving the car 14, and the rope 3 is removed from the pulley 2 of the speed governor 1. be able to.

[Effect of device]

Since the present invention is configured as described above, it is possible to remove the rope from the pulley of the governor without the need to move the car, and therefore, the work of releasing the car hoisting machine brake, There is an effect that the rope releasing operation is not required and the rope removing work can be performed safely and easily.
