Turnover hoisting method for gantry structure of stockyard stacker-reclaimer

Abstract

The invention belongs to the technical field of hoisting, and discloses a turnover hoisting method for a gantry structure of a stockyard stacker-reclaimer. Four first main hoisting points, two second main hoisting points, a first auxiliary tailing hoisting point and a second auxiliary tailing hoisting point are arranged on the gantry structure of the stockyard stacker-reclaimer; two main cranes and two tailing cranes are connected with the four hoisting points separately; the gantry structure of the stockyard stacker-reclaimer is jointly lifted through the two main cranes and the two tailing cranes to enable the gantry structure so that the gantry structure is separated from a placement support pier; then, the two main cranes raise and lift, the two tailing cranes lift and slip, till the gantry structure of the stockyard stacker-reclaimer is turned over and is upright; and the two tailing cranes are unhooked, and the gantry structure of the stockyard stacker-reclaimer is hoisted in place through the two main cranes. According to the turnover hoisting method, on the premise that the hoisting load capacity is reserved, the whole hoisting process is safe and stable, and the technology is reliable; the operation is completed on the ground, and high-altitude operation is avoided; and the torsion degree of equipment is reduced, not only is the construction safety guaranteed, but also the cost reduction and efficiency improvement are achieved.

Description

technical field [0001] The invention belongs to the technical field of hoisting, and in particular relates to a hoisting and turning method for equipment with a specific shape. Background technique [0002] With the rapid development of the national energy and chemical industry, in order to better optimize and utilize resources, the petrochemical industry is also constantly creating and developing new processes and technologies, so many new forms of equipment have emerged. These new forms of equipment are not only complex and diverse in type, but also more novel and irregular in shape, and their installation forms are also complex and diverse, which is accompanied by an increase in the difficulty of hoisting. Traditional hoisting methods are generally applied to structures with regular shapes. When hoisting irregular structures, the hoisting difficulty increases, and the equipment is easy to eccentric, resulting in shaking of the hoisting wire rope, which in turn makes the h...

Problems solved by technology

[0005] The present invention focuses on solving the technical problem of unstable hoisting of the stacker-reclaimer gantry structure in the stockyard, and provides a method for flipping and hoisting the gantry structure of the stacker-reclaimer in the stockyard, ingeniously setting multiple lifting points, using balance beams and The combined use of pulleys is realized through the "slip" cooperation of four cranes working together
