High-precision lifting hook connecting structure for tower crane

Abstract

The invention relates to the technical field of building machinery, and discloses a high-precision lifting hook connecting structure for a tower crane, the high-precision lifting hook connecting structure comprises a lifting device and a lifting hook, the top of the lifting device is provided with an extension lifting wheel, rotating shafts are connected to the two ends of the interior of the lifting device and the middle of the extension lifting wheel, and transverse plates are mounted at the two ends of the bottom of the lifting device; a monitoring device and a lighting device are arranged at the lower end of the transverse plate, the top of the lifting hook penetrates through the lifting device to be connected with a buffer plate, spring columns are distributed at the two ends of the bottom of the buffer plate in a welded mode, the inner side end of the lifting hook is connected with a locking rope, and a talkback calling device is arranged at the lower end of the side of the lifting device. A solar panel is arranged at the upper end of the side portion of the lifting device, and a fan is arranged in the middle of the interior of the lifting device. The high-precision lifting hook connecting structure for the tower crane is high in stability, capable of achieving intelligent monitoring and lighting, convenient to operate at night, safe, reliable, capable of achieving buffering and damping, capable of efficiently hoisting a rope for heat dissipation and dust removal, energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a high-precision hook connection structure for a tower crane. Background technique [0002] Tower cranes are referred to as tower cranes for short, also known as tower cranes, which originated in Western Europe. A rotating crane with the boom mounted on the top of a tall tower. The working space is large, and it is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, the boom and the base, etc. The working mechanism has four parts: lifting, luffing, slewing and walking. The electrical system includes motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc. [0003] At present, the existing high-precision hook ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-precision hook connection structure for tower cranes, which solves the problem of inconvenient and stable rotating and lifting ropes, which cannot be intelligently monitored and illuminated, and is difficult to be suitable for night work. The safety performance is insufficient and cannot Buffering and shock absorption, it is inconvenient to position and lock the hook, which may cause the lifting goods to fall, and the technical problems of unreasonable design
