Hoisting tool of wind screen of cooling tower and detaching and installing method of wind screen of cooling tower

Abstract

The invention discloses a hoisting tool of a wind screen of a cooling tower.. The hoisting tool (10) of the wind screen of the cooling tower comprises a main rod (11) and a suspension rod (12). The suspension rod (12) is fixed on the end part of the main rod (11) and vertical to the main rod (11). A pulley (13) is installed on the suspension rod (12). In addition, the invention further discloses a method for installing and detaching the wind screen of the cooling tower by using the hoisting tool. The invention can adopt the hoisting tool to install and detach the wind screen of the cooling tower, so that installation and detachment dead angles on the outer wall of the cooling tower can be prevented, and the wind screen can be fully hung on the outer wall of the cooling tower. Compared with the method for installing and detaching the wind screen by using automobile cranes, according to the method disclosed by the invention, the installation and detachment cost can be saved, and the installation and detachment period can be reduced.

Description

technical field [0001] The invention relates to the field of cooling towers in power plants, in particular to a hoisting tool for a cooling tower windshield and a method for disassembling and assembling the cooling tower windshield. Background technique [0002] In order to prevent the cooling tower from freezing in winter, it is necessary to hoist the windshield outside the cooling tower in October-November every year. By installing wind deflectors, drafts can be reduced and cooling towers can be prevented from freezing. From April to May of the coming year, due to the rise in temperature, it is necessary to remove the windshield to increase the ventilation of the cooling tower and strengthen the water cooling of the cooling tower. [0003] In the disassembly and assembly of the existing windshield, the disassembly and assembly of the windshield usually requires the use of a truck crane. That is, the windshield is lifted by a truck crane during installation, and then the ...

AI Technical Summary

Problems solved by technology

[0004] However, due to the influence of the ground environment and the limitation of the volume of the truck crane, there are positions that the truck crane may not be able to reach

In other words, there is a dead angle when the truck crane is hoisted, and all the windshields cannot be hung on the cooling tower, that is, the dead angle area of ​​the cooling tower is not covered by the windshield, and the cooling tower may freeze

[0005] In addition, with the help of a truck crane to disassemble and assemble the windshield, the operating cost may include car rental costs, lawn ground repair costs, labor costs, etc., so it has a relatively high operating cost

Moreover, when using a truck crane, it takes about five days to install a cooling tower, which makes the disassembly and assembly of the windshield relatively long
