Small lifting rack for building construction

Abstract

The invention discloses a small lifting rack for building construction. The small lifting rack for building construction comprises a clamping bracket and a rotary shaft base, wherein the rotary shaftbase is arranged at the top end of the clamping bracket, the clamping bracket and the rotary shaft base are fixedly connected in a welding mode, a fastening screw is arranged on the left side of the clamping bracket, a fastening screw is arranged on the left side, above the fastening screw, of the clamping bracket, a rotary shaft is arranged above the rotary shaft base, a fixed plate is welded tothe right end of the rotary shaft, a motor is arranged at the upper end of the fixed plate, a hinge fixing device is arranged at the upper end, located on the right side of the motor, of the fixed plate, a mechanical arm is arranged at the top end of the rotary shaft, a fixed pulley is arranged at the right top end of the mechanical arm, and the clamping bracket can balance a problem of centre-of-gravity shift by way of removing a counterweight base and the hinge fixing device can solve the problem of air suspension of a hoisted counterweight in a specific site, so that the stability and practicality of the small lifting rack can be improved.

Description

technical field [0001] The invention belongs to the related technical field of lifting frames, and in particular relates to a small-sized lifting frame for building construction. Background technique [0002] Small cranes, also known as cranes, small cranes, portable cranes, miniature cranes, miniature cranes, and electric cranes, are small mechanical devices with excellent performance and a wide range of applications. It is suitable for the lifting operation of high-rise buildings, such as various building materials and various decoration materials, especially for long and wide materials such as wooden boards and woodworking boards that are inconvenient to carry in corridors, and has its unique advantages. At the same time, it can also be used for loading and unloading machine tools of large workpieces in machining workshops, production and assembly lines of home factories, food factories, warehouses and household lifting items, etc. [0003] The existing technology has th...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: 1. In the use of the original small crane equipment, in order to prevent the center of gravity from shifting during the lifting process, a heavy object is often added to the base to lower the center of gravity. When being hoisted, the change of the center of gravity is a dynamic process. Adding heavy objects to the base cannot completely solve this problem. 2. During the hoisting operation, the original hoisting equipment does not have the function of hovering in the air
