Abstract

The invention discloses a safety lifting hook of a tower crane. The safety lifting hook comprises a lifting hook part and lifting rods; a counterweight block is arranged at the upper part of the lifting hook part; the mutually symmetrical lifting rods are arranged on the two sides of the counterweight block; a reel bracket is arranged on the counterweight block; a reel is arranged on the reel bracket, and is connected with a cross beam of the tower crane through a crane rope; lifting rod ropes are arranged on the lifting rods; and the lifting hook part is rotationally connected with a lifting hook baffle through a lifting hook rotating shaft. The safety lifting hook has the beneficial effects that the symmetrical lifting rods are arranged on the two sides of the counterweight block of the lifting hook of the tower crane, and when the lifting hook of the tower crane hooks and lifts tubular heavy objects or strip-type heavy objects and is unsafe, the objects can be bound and lifted through the two lifting rod ropes on the lifting rods. Through such mode, the incident safety problems of the lifting hook are solved, and the safety of ground staff is guaranteed.

Description

technical field [0001] The invention belongs to the related technical field of construction equipment, and in particular relates to a safety lifting hook of 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. my country's tower crane industry started in the 1950s. ...
