Description

  Embodiments described herein relate generally to an elevator balancing weight device.

  2. Description of the Related Art Conventionally, there has been known an elevator apparatus in which a car and a counterweight device are connected by a main rope, and the car is moved up and down by hoisting the main rope with a hoisting machine. When the main rope is connected to the riding cage and the counterweight device by the 1: 1 roping method, one end of the main rope is fixed to the rope hitch portion of the counterweight device.

  When renewing such an elevator apparatus, the hoisting machine may be replaced. When the hoisting machine is installed in the machine room provided in the upper part of the hoistway, the existing hoisting machine is removed in the machine room and the new hoisting machine is installed. However, since the hoisting machine is relatively large and has a large mass, it is difficult to install the hoisting machine in the machine room. For this reason, in order to improve the installation workability, there is a case where a smaller hoisting machine (ranking down hoisting machine) is adopted as a new hoisting machine than the existing hoisting machine. In this case, since the driving force of the hoisting machine is reduced, the main rope roping method is changed to the 2: 1 roping method that can reduce the hoisting torque rather than the 1: 1 roping method.

JP 2001-348176 A

  However, when the main rope and the counterweight device are connected by the 2: 1 roping method, a counterweight sheave for winding the main rope is required on the counterweight device instead of the rope hitch portion.

  In order to cope with such a situation, for example, a countermeasure can be considered in which the counterweight device before the renewal having the rope hitch portion (existing) is replaced with a new counterweight device having a counterweight sheave. . However, in this case, there is a problem that parts of the counterweight device before the renewal cannot be diverted and many waste products can be generated. In this case, the renewal cost increases.

  In addition, a countermeasure may be considered in which a counterweight sheave mounting hole is additionally processed in the counterweight device before renewal to mount the counterweight sheave. However, since the counterweight device is arranged near the wall of the hoistway (near the wall), it is difficult to remodel the counterweight device by performing additional processing at the site where the elevator device is installed. . For this reason, there is a problem that it is difficult to cope with the change from the 1: 1 roping system to the 2: 1 roping system.

  The present invention has been made in consideration of such points, and when changing from a 1: 1 roping system to a 2: 1 roping system at the time of renewal, the parts before renewal are diverted to generate waste. An object of the present invention is to provide an elevator balancing weight device that can be easily suppressed and cope with a change in the roping method.

  An elevator balancing weight device according to an embodiment is an elevator balancing weight device that is connected to an elevator car via a main rope. This elevator balancing weight device is attached to a main rope including a weight main body frame including a rope hitch portion that can be connected to the main rope by a 1: 1 roping method, a weight body mounted on the weight main body frame, and the rope hitch portion.
