Title:
COLUMN BENDING MOMENT ADAPTIVE BALANCING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/124510
Kind Code:
A1
Abstract:
A column bending moment adaptive balancing mechanism, comprising a column (10), a masthead (20), a working device (30), a lever-type balancing mechanism (40), a winch steel wire rope (50), and a back rope (60). The masthead (20) comprises a masthead frame (21) and a front fixed pulley block (22), the masthead frame (21) is mounted on the column (10), and the front fixed pulley block (22) is mounted at the front end of the masthead frame (21). The working device (30) is mounted on the column (10); the lever-type balancing mechanism (40) is hinged to the masthead frame (21); the winch steel wire rope (50) penetrates through the masthead frame (21), and is then wound between the front fixed pully block (22) and a movable pulley block (31) of the working device (30) by several turns, penetrates through one end of the lever-type balancing mechanism (40), and is finally fixed to the masthead frame (21); the back rope (60) is connected to the other end of the lever-type balancing mechanism (40). The column bending moment adaptive balancing mechanism can adaptively reduce the bending moment of the column, improve the stability of the column, reduce deformation of the column, and improve the hole forming quality of equipment.
