Driving system layout structure of 4:1 machine-room-free elevator

Abstract

The invention relates to the technical field of an elevator, in particular to a driving system layout structure of a 4:1 machine-room-free elevator, which is characterized in that: a wire rope is vertically wound downwards into a counterweight sheave A from a counterweight rope end, and the wire rope is vertically wound upwards into a guide sheave A after being led out from the counterweight sheave A; the wire rope is vertically wound downwards into the counterweight sheave B after being led out from the guide sheave A, and the wire rope is vertically wound upwards into a driving sheave after being led out from the counterweight sheave B; the wire rope is vertically wound downwards into a crosshead sheave A after being led out from the other end of the driving sheave and then is horizontally wound into a crosshead sheave B; the wire rope is vertically wound upwards into a guide sheave B after being led out from the crosshead sheave B, and the wire rope can be vertically wound downwards into a crosshead sheave D after being led out from the guide sheave B and then is horizontally wound into a crosshead sheave C; and the wire rope is vertically connected upwards to a cage rope end after being led out from the crosshead sheave C. The driving system layout structure has the advantages of reasonable and compact structure, reasonable utilization of shaft, simplicity and convenience in installation and positioning, higher driving capacity and longer service life of parts.

Description

Technical field: [0001] The invention relates to the technical field of elevators, in particular to a traction system layout structure of a 4:1 machine room-less elevator. Background technique: [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. As a means of transportation in the vertical direction, elevators have become important construction equipment in high-rise buildings and public places and are indispensable. With the development of computer technology, automation technology and power electronics technology, modern elevators have become typical mechatronic products. With the improvement of the overall national economic strength, people's living consumption level has increased significantly, and real estate developers have vigorously launched mid-to-high-end small high-rise and high-rise residential buildings, which has driven the rapid gr...

Problems solved by technology

In the existing machine room-less elevator, side guide wheels are provided on the counterweight side or the car side, so that the wrap angle of the traction wheel is less than 180°, the traction capacity of the whole elevator is low, and the wire rope is easy to run off, resulting in unilateral Abnormal wear of the guide shoes reduces the service life of the wire rope and the guide shoes. In addition, the layout of the existing machine room-less elevator traction system still has the disadvantages of unreasonable structural design and well utilization, difficult installation and positioning, and insufficient energy saving. Disadvantages of environmental protection and safety and comfort
