A hoisting device for prefabricated building parts

Abstract

A hoisting device for prefabricated prefabricated buildings, comprising a control box, two multi-stage hydraulic telescopic arms are symmetrically and fixedly installed at the left and right ends of the control box, and the two multi-stage hydraulic telescopic arms are coaxial and perpendicular to the left end face of the control box, The upper side of the multi-stage hydraulic telescopic arm on the left and right ends of the control box is provided with a first through hole, and the upper side of the multi-stage hydraulic telescopic arm is provided with a multi-stage telescopic shaft, and the inner end of the multi-stage telescopic shaft passes through the corresponding No. A through hole is located inside the control box, and the multi-stage telescopic shafts are connected with the corresponding first through-hole bearings. The number of the first bevel gears in each group is two, and the small diameter ends of the two first bevel gears in the same group are fixedly connected. The control box of the present invention can be fixedly installed on the upper part of the building through the bracket, can also be installed on the telescopic arm of a crane, and can also be installed on the boom of a tower crane for use.

Description

technical field [0001] The invention belongs to the field of hoisting devices, in particular to a hoisting device for prefabricated prefabricated buildings. Background technique [0002] With the continuous development of the construction industry, various concrete prefabricated parts have been widely used in various buildings. The production of concrete prefabricated parts generally adopts the combination of production line and transportation line. In the production process of prefabricated parts, due to the weight and volume of prefabricated parts, the transfer process is time-consuming and laborious. It is often necessary to use cranes or cranes to lift them, and then transfer them by prefabricated parts transport vehicles. However, hoisting prefabricated parts by driving or cranes not only takes up space, but also has low hoisting efficiency. The existing hoisting equipment is large in size and inconvenient for transportation; most of the existing hoisting equipment onl...

AI Technical Summary

Problems solved by technology

However, hoisting prefabricated parts by driving or cranes not only takes up space, but also has low hoisting efficiency. The existing hoisting equipment is large in size and inconvenient for transportation; most of the existing hoisting equipment only Lifting both ends will easily lead to unbalanced force on the prefabricated parts, which will easily lead to dangerous situations such as deformation or breakage; the existing prefabricated parts lifting device has a complex structure and large volume, and the position of the lifting point cannot be adjusted according to the length of the floor and prefabricated slabs , it is difficult to ensure the stability during hoisting; the number of steel wire ropes that the existing hoisting equipment bears is small, and if the wire rope breaks, it is easy to cause the prefabricated parts to fall, which is likely to cause life danger to the construction workers
