Description

  The present invention relates to a drive device support structure for a traction elevator that eliminates the need for a machine room in which the elevator drive device is installed.

  In recent years, for the purpose of eliminating the machine room of the rope type elevator provided at the top of the hoistway due to the problem of the right of sunshine, an elevator in which a hoisting machine is installed in the gap between the carriage and the hoistway wall has been proposed.

  Examples thereof are described in Japanese Utility Model Publication No. 4-50297 (“small elevator device”) or Japanese Patent No. 2593288 (“traction sheave elevator”).

  In the example of actual fair 4-50297, as shown in FIG. 18, an electric motor is used as the driving device 53, and the car 55 and the counterweight 56 are suspended in a slidable manner. A traction sheave 57 is arranged above the hoistway 54, a car 55 is arranged at one end of a suspension rope 58 wound around the traction sheave 57, a counterweight 56 is arranged at the other end, and the traction sheave 57 is driven by an electric motor. The driving force is transmitted to the suspension rope 58 by the friction between the suspension rope 58 and the traction sheave 57, and the car 55 and the counterweight 56 are moved up and down. In this structure, since the drive device 53 is large, the conventional machine room is not required by enlarging the hoistway 54, and the drive device 53 is arranged in an empty space of the hoistway 54.

  In the example of Japanese Patent No. 2593288, as shown in FIGS. 19A and 19B, the operation principle is basically the same as that of FIG. An electric motor is used as the driving device 53, and a car 55 and a counterweight 56 are suspended in a slidable manner. A traction sheave 57 is disposed at the upper part of the hoistway 54, a car 55 is disposed at one end of a suspension rope 58 wound around the traction sheave 57, and a counterweight 56 is disposed at the other end. The traction sheave 57 is driven by an electric motor. Thus, the driving force is transmitted to the suspension rope 58 by the friction between the suspension rope 58 and the traction sheave 57, and the car 55 and the counterweight 56 are moved up and down. However, in the structure according to the present system, as a method of disposing the driving device 53 in the empty space of the hoistway 54, the driving device 53 is attached to the balance weight guide rails 59a and 59b via a fixing member, and the driving device 53 is attached. The suspension rope 58 passes through turning pulleys 60a to 60c for the purpose of disposing in the empty space of the hoistway 54. This arrangement makes a conventional machine room unnecessary.

  In the example of the driving device support structure in which the driving device is installed in the gap between the top of the hoistway, the hoistway wall and the car described with reference to FIG. 18, the rotation surface of the traction sheave 57 is arranged so as to be orthogonal to the side surface of the car. Therefore, the size of the gap between the car and the wall has to be larger than that of a normal elevator, and there is a problem that the effective use area of the building is reduced.

  In addition, in another example described with reference to FIG. 19, when the rated load capacity of the car increases, the thickness of the traction sheave 57 increases, so that the car cannot fit into the gap of the hoistway wall. Since the drive device is supported by the guide rail, there is a problem that the load on the guide rail is increased and it is impossible to cope with the increase in the size of the elevator. In addition, since the return car is provided in the car, the support structure of the driving device is complicated, the number of parts is increased, and there are problems in terms of cost and installation maintenance.
