Contactless lifting sling system for towering precious metal tower mast

Abstract

The invention provides a contactless lifting sling system for a towering precious metal tower mast. A contactless lifting sling comprises a cross-shaped torsion-resistant hanging scaffold type annular loop, four vertical expandable rods, contactless safe supports connected with the upper portions, the lower portions and the bottoms of the rods correspondingly, a lower annular loop and claw-like plug-in overhanging stress lever supports. A blind penetrating installation guide structure comprises an upper flange plate, a lower flange plate and fan-shaped wedges, wherein the upper flange plate and the lower flange plate are both provided with bolt holes in a corresponding mode; flange plate bolts are installed in the bolt holes of the lower flange plate, and guide rods are connected to the ends, away from bolt caps, of the flange plate bolts; and the fan-shaped wedges are inserted into the gap between the upper flange plate and the lower flange plate which are connected. According to the contactless lifting sling system for the towering precious metal tower mast, the towering precious metal tower mast can be lifted without damage, so that the towering precious metal tower mast is safe enough in the lifting process; and horizontal and perpendicular moving, precise installation and one-time in-place of the towering precious metal tower mast under the undamaged condition can be achieved, and high-altitude disassembling and assembling of the lifting sling are quick and convenient.

Description

technical field [0001] The invention relates to a non-contact suspender system for a tall noble metal tower mast. 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] With the rise of...

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
