Wallboard lifting equipment used for green buildings

Abstract

The invention belongs to the technical field of lifting, and particularly relates to wallboard lifting equipment used for green buildings. The wallboard lifting equipment comprises steel wire ropes and a mounting block. According to the wallboard lifting equipment, through designed sliding blocks, second gear and winding wheel, during use, after one of the two steel wire ropes is broken, the two sliding blocks draw close to the middle through the ingenious design, so that the hanging point of the unbroken steel wire rope and mounting block is moved to the midpoint of the mounting block as muchas possible to prevent that the lifting equipment swings back and forth under the gravity action of and assembled wallboard and equipment to generate a relatively large dynamic load on the remainingsteel wire rope, so that the assembled wallboard falls to endanger the safety of life and property on the ground. Limiting columns perform reverse moving limiting of corresponding first racks so as toachieve the purpose that after the two sliding blocks slide to the middle of the mounting block when one of the steel wire ropes is broken, the situation that the mounting block laterally swings dueto the fact that the barycenter of the assembled wallboard possibly deviates from the center of the mounting block is prevented.

Description

[0001] Technical field [0002] The invention belongs to the technical field of lifting, and in particular relates to a wallboard lifting device for green buildings. Background technique [0003] With the development of green buildings, prefabricated buildings with less pollution are becoming more and more popular. Tower cranes are used for hoisting wall panels. In order to increase the stable lifting of wall panels, there are generally special lifting equipment. It is connected with the wall beam by wire rope. Although the wire rope has a large safety factor, after long-term use, it is inevitable that one or more wire ropes on one side will be squeezed and break during use. However, after the wire rope breaks, Because the lifting equipment is out of balance, although the remaining steel wire ropes have the ability to prevent the wallboard from falling, after the balance is lost, the wallboard will swing due to its gravity, which will generate a large dynamic load on the remai...

[0003] With the development of green buildings, prefabricated buildings with less pollution are becoming more and more popular. Tower cranes are used for hoisting wall panels. In order to increase the stable lifting of wall panels, there are generally special lifting equipment. It is connected with the wall beam by wire rope. Although the wire rope has a large safety factor, after a long time of use, it is inevitable that one or more wire ropes on one side will be squeezed and break during use. However, after the wire rope breaks, Because the lifting equipment is out of balance, although the remaining steel wire ropes have the ability to prevent the wallboard from falling, after the balance is lost, the wallboard will swing due to its gravity, which will generate a large dynamic load on the remaining steel wire ropes, and the dynamic load may If it is higher than the maximum bearing capacity of the remaining wire ropes, it is very likely to cause the wallboard to fall, endangering life and property on the ground. This invention designs a hoisting device. When one side of the wire rope breaks and the wallboard loses balance, The dynamic load of the wire is necessary
