A free lifting system for working aloft comprises a base 1. The free lifting system for working aloft is characterized in that a rotary chassis 2 is arranged on the base 1; a motor 3 and a support 4 are arranged on the rotary chassis 2; a power output shaft of the motor 3 is connected with a first transmission shaft 6 arranged on the support 4 through a reducing gear 5; a first transmission wheel 10 is arranged on the first transmission shaft 6; the first transmission shaft 6 is connected with a first lifting shaft 8 arranged on the support 4 through a first clutch 7; the first lifting shaft 8 is provided with a first arrester 9 and a lifting device 11; and the first clutch 7 and the first arrester 9 are connected with a power supply control tray 18 which is arranged on the rotary chassis 2 through a power cord 17. In the free lifting system, a plurality of sections of lifting rod pieces are mutually connected to form an extensible lifting system, and the motion of each rod piece is not restricted by the motion or stopping of adjacent rod pieces, thereby the invention has remarkable characteristics of fast lifting, free height adjustment, stopping and turning function after lifting, safety, reliability and convenient use.
Description
technical field [0001] The invention relates to the technical field of lifting equipment for working at heights, in particular to a free lifting system for working at heights. Background technique [0002] At present, the lifting equipment used for high-altitude operations generally adopts hydraulic system lifting, which requires high manufacturing precision, high manufacturing cost, and the lifting height is limited. Flexibility is limited. This is far from meeting the needs of higher space operations, especially with the development of science and technology, the construction of super high floors, and the fire protection of super high floors are issues that must be considered. Contents of the invention [0003] The object of the present invention is to provide a self-locking lifting system for high-altitude work in view of the defects in the prior art, which adopts multi-section lifting rods connected by shafts to form an expandable multi-stage lifting system, thereby e...
