Arrangement structure of elevator without machine room

Abstract

The invention provides an arrangement structure of an elevator without machine room. The arrangement structure comprises a car going up and down in a shaft; a single beam is arranged on an inner wall of one side of the shaft, while a main track and a second rope head rack are arranged on an inner wall of the other side of the shaft; the single beam is arranged horizontally, and the two ends thereof are fixedly connected to the front and rear walls of the shaft, respectively; the main track is arranged vertically; a traction machine is fixedly connected to the single beam and arranged in a length direction of the single beam; a diversion sheave is arranged on the top of a counterweight device in a vertical direction and arranged in a tilting manner relative to the single beam; one end of a tow rope is fixed on a first rope head rack through the traction machine and the diversion sheave, while the other end of the tow rope is fixed on the second rope head rack through a car bottom sheave located at the bottom of the car. By means of the solution, the single beam is arranged to serve as a load-carrying part, and is good in load-carrying effect, high in strength, high in practicability and relatively low in cost, and further, the height of a top layer of the shaft is reduced; the traction machine is transversely placed on the single beam, and balanced stress is applied to both sides of the traction machine without unbalance loading, and therefore, smooth running of the elevator is guaranteed, and the elevator is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an arrangement structure of an elevator without a machine room. Background technique [0002] In the existing elevator technology, elevators are divided into machine-room elevators and machine-room-less elevators according to the shaft form. Machine-room elevators are safe and reliable in structure, but they are expensive and take up space. Machine-room-less elevators can effectively save costs and space, and machine-room-less elevators are more and more widely used. With the development of machine-room-less elevators, more and more attention has been paid to the safety and reliability of elevators. However, the load-bearing of existing machine-room-less elevators often adopts a double-beam structure, which is cumbersome to install, with low space utilization and high cost. Contents of the invention [0003] In view of this, the present invention aims to propose a machine-ro...
