Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] figure 1 The method of winding the rope 5 of the elevator apparatus in the first embodiment of the present invention is shown. figure 2 It is a top sectional view of the hoistway in the elevator apparatus of this embodiment. image 3 This is a cross-sectional view of the hoisting machine in the elevator apparatus of this embodiment. Figure 4 It is a right side view of the hoistway in the elevator apparatus of this embodiment. Figure 5 It is a front view of the hoistway in the elevator apparatus of this embodiment.

[0024] The elevator apparatus of the present embodiment is configured such that the elevator car 1 is raised and lowered along the guide rails 16a and 16b for the elevator car, and the balance weight 12 is raised and lowered along the guide rails 17a and 17b for the balance weight. In addition, the elevator car 1 and the counterweight 12 are suspende...

Abstract

An elevator device is provided. In the elevator device of the present invention, the elevator car (1) and the balance counterweight (12) suspended by the sling (5) are driven in the hoistway by the winch, wherein there is a The suspension pulley (8), the sling fixing part (4) arranged on the elevator car (1), the suspension pulley (13) arranged on the top of the balance weight (12), and the suspension pulley (13) arranged on the balance weight (12) ), the vertical projection of the driving sheave (11) of the hoist does not overlap with the vertical projection of the elevator car (1), and the braking part (21) of the hoist or the position detector ( 22) The vertical projection of the opposite end of the drive sheave (11) is located within the vertical projection of the elevator car (1). The driving device of the elevator device is small in size, and the maintenance work of the braking part or the position detector can be easily performed.

Description

Technical field [0001] The present invention relates to an elevator device. The elevator car and balance weight of the elevator device move along guide rails in a hoistway. Background technique [0002] As the prior art, an elevator device that suspends an elevator car and a counterweight in a 3:1 winding manner has been disclosed. For example, the elevator device disclosed in the following patent document 1 reduces the tension applied to the sling to two-thirds compared with the elevator device using the traditional 2:1 winding method, thereby reducing the tension applied to the drive. The hoisting moment on the device, as a result, can realize the miniaturization of the drive device. [0003] Patent Document 1: JP 2004-83231 Bulletin (paragraph No. 0023 and figure 1 , Figure 7 Wait) [0004] However, in the elevator apparatus disclosed in the aforementioned Patent Document 1, the vertical projection of the end portion on the opposite side of the sheave of the drive apparatus ...
