Problems solved by technology

[0004] Including the elevator device described in Patent Document 1, in the existing non-counterweight elevator device, since the main rope 6 is connected to the upper part and the lower part of the car room 1, the rope end devices 8a and 8b are connected to the There is a problem that the space inside the shaft 7 cannot be effectively used and the size of the shaft 7 becomes large due to the interference of various devices on the top of the shaft 7 and the bottom pit.
On the other hand, since the above-mentioned problem can also occur between the hoisting machine 9 installed in the pit portion of the hoistway 7 and the rope head device 8b installed below the car room 1, the car 5 can reach the At the bottom of the lifting range, the rope end device 8b also tilts

Abstract

A balance weight-less elevator apparatus enabling a reduction in the size of the hoistway of an elevator by minimizing spaces at the tip part and the pit part of the hoistway is closed. The elevator apparatus comprises a car lifting in the hoistway of the elevator, drive pulleys or return pulleys installed at the tip part and the pit part of the hoistway, and main ropes wrapped around the drive pulleys or the return pulleys and having one end parts fitted to the car from the upper side of the car and the other end parts fitted to the car from the lower side of the car. Both end parts of the main ropes are fitted to one side-face of the car, and one end parts of the main ropes are fitted to one side-face lower part of the car from the upper side or the other end parts of the main ropes are fitted to one side-face upper part of the car from the lower side.

Description

technical field [0001] The present invention relates to an elevator installation without a counterweight (a counterweight-less elevator installation). Background technique [0002] The traction type non-counterweight elevator device usually has such a structure that each end of the main rope is connected to the car of the elevator, and the car of the elevator is raised and lowered in the hoistway in conjunction with the rotation of the driving sheave on which the main rope is wound. . Figure 4 It is a front view of a conventional counterweight-less elevator apparatus having such a structure, and shows a schematic structure of an elevator apparatus described in Patent Document 1 below. exist Figure 4 Among them, the car chamber 1 on which elevator users ride when moving is fixed to the car frame 3 by buffer members 2 and the like. On the car frame 3, one end of the main rope 6 is elastically arranged on the central part of the upper frame 3c through the rope end device 8a,...
