Installation method of non-contact spreader for high tower mast of precious metal

Abstract

The invention provides an installation method of a non-contact-point lifting appliance for a towering noble metal tower mast. The method comprises the steps that four vertically-unfolded rods, a non-contact insurance support and a lower hoop of the non-contact-point lifting appliance are opened; a claw-shaped insertion type cantilever stress lever support of the non-contact-point lifting appliance is inserted into a preformed hole in the lower portion of the towering noble metal tower mast; the lower hoop is connected to the four vertically-unfolded rods; the non-contact insurance support is extended in place to fix and support the towering noble metal tower mast; and after the non-contact-point lifting appliance is hoisted in place through a crane, the non-contact-point lifting appliance is dismounted from the towering noble metal tower mast. The installation method can hoist the towering noble metal tower mast without damage, and can support the towering noble metal tower mast and protect the towering noble metal tower mast against damage by external force friction, so that the hoisting process is safe enough, horizontal and vertical movement and accurate one-time installation in place of the towering noble metal tower mast without damage and high-altitude dismounting and mounting rapidness and convenience of the lifting appliance can be achieved, and one-time hoisting is achieved.

Description

technical field [0001] The invention relates to an installation method of a high-rise noble metal tower mast non-contact spreader. Background technique [0002] In construction projects, it is often encountered that the tower mast cannot be mechanically installed by mechanical equipment such as tower cranes, and there is no place for the tower crane to attach to the wall on site. The components are often lifted and spliced ​​by pulling rods, which has the characteristics of high construction difficulty and high risk factor. On the other hand, there are many tower mast parts, and the assembly is complicated. Its technical requirements are also relatively high, especially when it comes to the tower mast structure of precious metals. The composition of its artistic components is more complicated than that of ordinary tower masts, and the requirements for the protection of semi-finished products are more stringent. The on-site hoisting must be non-destructive hoisting. [0003]...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to bind and fix the components before lifting, which will damage the surface of the hanger to varying degrees. At present, there is no suitable non-contact and non-destructive lifting tool;

[0005] 2. The component needs to be split into multiple units for multiple positioning, and the installation speed is slow;

[0006] 3. For high-altitude hoisting, it is necessary to set up supporting scaffolding equipment of more than 50m;

[0007] 4. It cannot be hoisted as a whole at one time, and it is necessary to use vertical transportation equipment to transport the components to a high place in advance, making the construction more difficult;

[0008] 5. It is inconvenient to disassemble and assemble at high altitude, and the safety is insufficient

[0009] Therefore, the above-mentioned existing hoisting technology cannot meet the hoisting requirements of precious metal tower masts. In order to ensure that the surface gold layer and exquisite carvings are not damaged during the overall hoisting process, the traditional binding method cannot be used for hoisting. Therefore, there is an urgent need Design special precious metal tower mast non-contact overall hoisting supporting spreader
