Turnover device and method used for single crane hoisting of prefabricated stand pillars

Abstract

The invention discloses a turnover device and method used for single crane hoisting of prefabricated stand pillars. The device comprises a roadbed box detachably installed on the horizontal plane and turnover mechanisms installed on the roadbed box. In the single crane hoisting process of the prefabricated stand pillars, the ends, away from the hoisting point, of the prefabricated stand pillars are connected to the turnover mechanisms; the turnover mechanisms provide supporting points for the single crane hoisting turnover of the prefabricated stand pillars. By means of the scheme, the defects that the cost is high, pillar legs are prone to being destroyed and safety is poor in the prior art can be overcome, and the beneficial effects of reducing the cost, protecting the pillar legs and improving safety can be achieved.

Description

technical field [0001] The invention relates to the technical field of bridge prefabricated assembly construction, in particular to an overturning device and method for single-machine hoisting of prefabricated columns. Background technique [0002] With the promotion and popularization of prefabricated assembly construction technology in urban bridge construction, a large number of prefabricated columns need to be hoisted during the construction process. When hoisting, the prefabricated columns transported horizontally to the site need to be turned 90 degrees to be vertical for hoisting. [0003] Due to the heavy weight of the prefabricated column itself, the traditional method needs to use two cranes to turn over, which requires a lot of equipment and labor, and the cost is high; however, the method of placing the column foot directly on the ground and turning it over with a crane will cause Problems such as column foot damage. [0004] In the prior art, there are defects...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the above-mentioned defects and propose a flipping device and method for single-machine hoisting of prefabricated columns to solve the problem of saving lifting equipment and supporting operators by providing support fulcrums for the single-machine hoisting and flipping of prefabricated columns, effectively reducing the Safety risks at the hoisting site, reducing construction land occupation and impact on surrounding traffic, so as to save costs, protect column feet and improve safety, etc.
