Description

  The present invention relates to an improvement in an elevator rope attachment device for fixing a rope for driving a car or the like up and down at an end.

  Rope type elevators with a 2: 1 roping method are generally provided with a car sheave at the top of the car, and the rope (main rope) hung over the car sheave is hung on the drive sheave of the hoisting machine. It is passed over to a counterweight sheave provided at the top of the counterweight.

  With the above configuration, both ends of the rope are fixed to the machine beam in the machine room in which the hoisting machine is installed.

  In recent rope type elevators, a machine room is often not provided on a hoistway due to problems such as effective use of buildings in buildings and the right to sunshine.

  FIG. 11 is a configuration diagram showing a conventional rope attachment device in a rope type elevator in which no machine room is installed.

  That is, a car (not shown) moves up and down along the guide rail 1, but the end of the rope 2 that suspends the car is connected and fixed to the rope attachment device 3 via the shackle rod 2a. The device 3 is attached to the guide rail 1 by a bolt 1a.

  The rope attachment device 3 is made of an L-shaped member, and includes a base portion 3a fixed to the back surface of the guide rail 1, and a rope support portion 3b extending in the horizontal direction from the upper end portion of the base portion 3a. The end of the rope 2 is attached to the rope support 3b via the shackle rod 2a (see Patent Document 1).
