Lifting rod based on pulley principle

Abstract

The pulley principle lifting rod comprises a first-stage pipe joint, a middle pipe joint, a last-stage pipe joint and a steel wire rope, the last-stage pipe joint is arranged in the middle pipe joint, a middle pulley mounting seat is arranged at one end of the bottom of the middle pipe joint, and middle inner pulleys are arranged on the two sides of the bottom of the middle pulley mounting seat; the steel wire rope is controlled to be wound and unwound, the lifting rod is controlled to ascend and descend, the structure is simple and compact, carbon fiber materials of the pipe joints are matched, the steel wire rope is controlled to be wound and unwound, the steel wire rope is controlled to be wound and unwound, the lifting rod is controlled to ascend and descend, and the steel wire rope and the steel wire rope are controlled to be wound and unwound. The self weight of the lifting rod is greatly reduced, more middle pipe joints can be installed, the lifting height of the lifting rod has a wider application range, meanwhile, through cooperation of the steel wire rope and the pulley block, section-by-section lifting is achieved when the lifting rod ascends and descends, and the lifting process is more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of lifting rods, in particular to a lifting rod based on a pulley principle. Background technique [0002] Lifting poles are widely used in golf course lighting, transportation, fire protection, various surveillance, monitoring, environmental monitoring, engineering mobile lighting, road administration, military, communication and other fields. It plays an important role in various natural disasters, emergency communication lighting at night at the scene of emergencies, and rescue. [0003] Due to its simple structure and simple and reliable operation, the lifting rod is widely used in lifting equipment in the fields of daily life, communication, and fire protection. The pipe joint assembly includes a first-stage pipe joint, an intermediate pipe joint and a final-stage pipe joint that are sequentially socketed in a reciprocating and slidable manner from outside to inside. According to different use environ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a pulley-based lifting rod to solve the problem that the existing production lifting rods proposed in the above background technology generally use screw rods or hydraulic structures for lifting. This structure is complex, heavy and costly. And there are generally weak carrying capacity, poor stability, and unreliable shortcomings.
