A method for segmental hoisting and aerial assembly of heavy-duty tower equipment

Abstract

The invention discloses a hoisting and overhead-assembling method for sections of heavy tower equipment, and belongs to the technical field of equipment manufacturing and mounting. The hoisting and over-head assembling method comprises the following steps of: mounting supporting tools on the peripheral wall, close to an assembling and welding position, of a lower section of a tower, and welding guide posts on each tool; mounting guide rings on positions, above an assembling welding seam, of a to-be-hoisted tower section, uniformly distributing the guide rings on the peripheral wall, close to the assembling and welding position, of the lower section of the tower so as to correspond to the guide posts on the lower section of the tower, hoisting the upper section of the tower to the upper part of the lower section of the tower, pulling, regulating and controlling the direction of the upper section of the tower through a hemp rope which is tied and suspended in advance, dropping a lifting hook, nesting guide rings mounted on the lower part of the upper section of the tower into the guide posts mounted on the upper part of the lower section of the tower, and guiding the upper tower section and the lower tower section to quickly and precisely align. The invention designs a brand-new hoisting and perpendicularly assembling method for sections of heavy tower equipment. With the adoption of the technical scheme, assembling for the upper section and the lower section can be completed more safely, quickly and precisely.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing and installation, and more specifically, relates to a construction method in which the equipment hoisting section and the lower section of the installed equipment are accurately and quickly combined in the air during the section hoisting of heavy tower equipment. Background technique [0002] With the large-scale design of petrochemical production equipment, there are more and more large-scale and heavy-duty tower equipment in construction projects. However, due to the limitation of transportation conditions, often some over-limit equipment cannot be transported into the construction site as a whole, and can only be transported in sections. Field, and then group butt welding. On-site pairing can be divided into horizontal pairing and vertical pairing. Horizontal pairing is due to the large construction site required, the need to use supporting roller support frames, and the need to...

Problems solved by technology

The key process of vertical alignment is the matching operation of the upper and lower sections of the equipment. The upper section of the hoisted equipment is affected by the high-altitude wind force and the crane's lifting, luffing, rotating, etc., and the shaking is relatively large. In the past construction, it was carried out manually. Control the shaking of the upper cylinder of the equipment and complete the assembly of the upper and lower cylinders, which requires more construction workers, high labor intensity, low efficiency, and difficult to guarantee the accuracy of the assembly
