Multifunctional rotating adjusting lifting appliance special for section beams

Abstract

The invention discloses a multifunctional rotating adjusting lifting appliance special for section beams. The lifting appliance comprises a lifting column and a supporting disc rotationally arranged at the bottom end of the lifting column, wherein a driving motor used for driving the supporting disc to rotate is further arranged on the lifting column; the outer side of the supporting disc is symmetrically and fixedly provided with two cantilever beams, and each cantilever beam is provided with a horizontal adjusting piece used for adjusting the horizontal position of supporting columns; and each supporting column is provided with a height-adjustable lifting supporting plate, and the lifting supporting plates are further provided with locking assemblies used for locking and fixing the lifting supporting plates. According to the embodiment, the cantilever beams of the lifting appliance can be rotated, the problem that the placed angle of the section beams is different is solved, and thelifting supporting plate arranged on a supporting part has the advantages of being flexible in adjustment and stable in structure.

Description

technical field [0001] The invention relates to a hoist, in particular to a special multi-function rotary adjustment hoist for segmental beams. Background technique [0002] At present, with the development of science and technology, the modern construction industry pays more and more attention to speeding up the project progress and product quality through technology, and component prefabrication has gradually become the development trend of engineering construction. In highway and bridge engineering, the prefabrication of beams and slabs has become the first choice of the industry, which not only speeds up the progress of the project, saves cost and resources, but also improves the overall quality of the project. [0003] The spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used lifting tools for lifting items are hooks and slings, and others include rings, lifting suction cups, clamps and forks. It is widely used in th...

AI Technical Summary

Problems solved by technology

Due to the placement angle of the segmental beams in the beam field, the existing spreader has a large error in the size of the hoisting hole, and the fixed spreader cannot solve this problem. Moreover, when the spreader is in use, its adjustment flexibility to the support plate of the suspended object is relatively small. Poor, and the stability is not high, it is easy to cause the failure of the support plate loaded with objects, and the safety is low
