Embodiment approach 1

[0031] figure 1 It is a general configuration diagram showing an elevator apparatus according to Embodiment 1 for carrying out the present invention.

[0032] exist figure 1 Among them, the hoistway 1 has: the car 2, which is used to carry passengers and lift; the guide rails 3a and 3b of the car 2, which are respectively arranged on both sides of the car 2, are used to guide the lifting of the car 2; the counterweight 4, which lifts in the direction opposite to the lifting direction of the car 2; and the guide rails 5a, 5b of the counterweight 4, which are respectively arranged on both sides of the counterweight 4, for guiding the lifting of the counterweight 4. On the upper side of the counterweight 4 and in the upper part of the hoistway 1, a traction machine 6 serving as a power source for raising and lowering the car 2 and the counterweight 4 is provided. The hoisting machine 6 has a driving sheave 6a around which the suspension unit 10 suspending the car 2 and the co...

Abstract

An elevator device in which bending moment on a guide rail is reduced. The elevator device has a hoist installation section on which a hoist is installed and placed so that, when viewed in the horizontal direction, at least a portion of the hoist installation section is included in a region in the longitudinal direction of the guide rail. A rail installation section is attached to the hoist installation section so as to be in the region in the longitudinal direction of the guide rail. The rail installation section is also attached to the guide rail so as to cover the installation range, in the longitudinal direction of the guide rail, of the hoist installation section.

Description

technical field [0001] The present invention relates to a mounting structure for mounting a traction machine installed in a hoistway on a guide rail in an elevator apparatus in which the traction machine is installed in the hoistway. Background technique [0002] In an existing elevator device, a support platform is installed on a guide rail for guiding the counterweight to go up and down, and the installation part on which the traction machine is installed is installed on the support platform through an elastic member. The mounting member is held so as to be slidable in the longitudinal direction of the guide rail, and anti-vibration members are provided above and below the mounting member to prevent vibration of the mounting member in the horizontal direction. The anti-vibration component clamps the guide rail via the elastic component. [0003] The hoisting machine has a driving sheave on which a main rope serving as a suspension unit for suspending the car and the count...
