Title:
WINDING STRUCTURE OF TRACTION TYPE BUILDING CONSTRUCTION ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2021/035864
Kind Code:
A1
Abstract:
A winding structure of a traction type building construction elevator, comprising a traction medium (1), a first reversing wheelset (2), a second reversing wheelset (3), a traction machine (4), a third reversing wheelset (5), and a fourth reversing wheelset (6). One end of the traction medium (1) is sequentially reversed by the second reversing wheelset (3) and the first reversing wheelset (2), and then is connected to a suspension cage (7) in a mode of fixing a middle part; the other end of the traction medium (1) is sequentially reversed by the third reversing wheelset (5) and the fourth reversing wheelset (6), and then is connected to a counterweight (8); an elevator changes the direction of the traction medium (1) of a hoistway traction machine (4) by means of a horizontal beam (9) and the winding structure, and can pull the suspension cage (7) to move up and down; the horizontal beam (9) can move up and down. The winding structure has the advantages of being high in lifting efficiency and low in noise. The traction medium (1) is connected to the suspension cage (7) in the mode of fixing the middle part, and a sufficient length of traction medium is reserved at one end of the traction medium (1), and therefore, the reserved traction medium (1) can be directly used in the floor-adding process of a building, the traction medium (1) does not need to be cut off, and a continuous wire connecting and extending mode does not need to be used, either.
