Problems solved by technology

However, when the material is fixed by the hook and transferred, the telescopic boom will cause the material to shake in the air. The single sling fixation can easily cause the material to tilt or rotate, and even cause the material to be thrown or fall off, causing material and personnel safety issues.

Abstract

The invention discloses a mechanical hoisting apparatus. The apparatus comprises a pedestal; a rotary table which can rotate horizontally is arranged on the pedestal; a hoist boom is arranged on the rotary table, the hoist boom is provided with the first hoister, and the top of the hoist boom is provided with a pulley for carrying articles; a suspension cable in the first hoister protrudes and extends as well as surrounds a pulley for loading articles at the top of the hoist boom, and the end of the suspension cable is provided with a main suspension hook; the end of the hoist boom far from the rotary table is provided with a horizontally arranged slide arm, and the side arm is provided with an electric hoist which can move along the slide arm. An auxiliary suspension hook which protrudesby the electric hoist is matched with the main suspension hook, in order to realize the effects for facilitating fixation of articles and enhancing stability of fixed articles; compared with the single suspension cable fixed article, the electric hoist and double suspension cables of the first hoister are used for carrying out fixation of double ends of the articles which need to be carried, and judgment of center of gravity of an object and selection of fixed hoisting points, adjustment and other workloads are reduced; inclination resistance and migration capability of the object during air suspension and movement are enhanced, and throwing and falling probability of the object are reduced.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a mechanical hoisting device. Background technique [0002] In the prior art, the Chinese patent document whose application publication number is CN105621286A discloses a material hoisting device with a retractable boom. A turntable that can rotate horizontally is installed on the base. There is a guide groove, one end of the boom is connected to the inner wall of the guide groove through a spring, and the other end is exposed to the guide groove and is equipped with a guide wheel. The lifting rope connected with the hook passes through the guide wheel and connects to the hoisting winch on the boom . A stretching wheel is installed on the side of the boom, and a stretching winch matched with the stretching wheel is installed on the side of the boom. One end of the stretching rope is connected to the stretching winch, and the other end is fixedly connected to the boom after bypassing the stre...
