Hoisting device for green building assembly type building assembly wallboard

Abstract

The invention belongs to the technical field of hoisting, and particularly relates to a hoisting device for a green building assembly type building assembly wallboard. The device comprises steel wireropes and an installation block. According to the device, in the using process, after one of the two steel wire ropes is broken, two sliding blocks are closed towards the middle through ingenious design, the hanging point of the unbroken steel wire rope and the installation block moves to the middle point of the installation block as much as possible, and the facts that the hoisting device reciprocates to swing under the action of gravity of an assembly wallboard and the device, large dynamic loads are generated on the remaining steel wire ropes, the assembly wallboard falls off, and the lifeand property safety on the ground is endangered are prevented. When one of the two steel wire ropes breaks, an installation sliding block on the side moves downwards relative to the corresponding sliding block, and the installation sliding block moves downwards to trigger a corresponding limiting mechanism, so that the limiting mechanism on the side controls the other limiting mechanism to limit an installation sliding block on the other side through the transmission of a gear and a rack; and the resistance in the sliding block moving process is reduced.

Description

[0001] Technical field [0002] The invention belongs to the technical field of lifting, and in particular relates to a lifting device for green building assembly type building assembly wall panels. 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 ...

[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
