Tower type hauling-up device capable of effectively bolting and anchoring lifting arm

Abstract

The invention discloses a tower type hauling-up device capable of effectively bolting and anchoring a lifting arm. The tower type hauling-up device comprises a base, a counterweight body, a lifting hook, a connecting bolt and a connecting block. A tower frame is welded to the upper side of the base, and a climbing ladder is welded to the right side of the tower frame. A fixed frame is mounted on the right side of the counterweight body. The lifting arm is fixedly connected to the inner side of the fixed frame, and the upper end of the lifting hook is connected with the lifting arm. The connecting bolt is internally embedded into the fixed frame, the inner side of the connecting block wraps the lifting arm, and a connecting frame is mounted on the upper side of the connecting block. According to the tower type hauling-up device, the connecting mode between traditional main components is changed, so that connecting is more convenient and stable; and meanwhile the anti-shaking capacity ofthe device is improved, and the use safety of the device is greatly improved.

Description

technical field [0001] The invention relates to the field of tower lifting devices, in particular to a tower lifting device capable of effectively bolting and anchoring booms. Background technique [0002] Tower crane (tower crane) referred to as tower crane, also known as tower crane, originated in Western Europe. The installation of components consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes tower body, boom and base, etc. The working mechanism includes four parts: lifting, luffing, slewing and walking. The electrical system includes motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices. [0003] Most of the current tower cranes are connected by welding between the tower body and the boom, which is easy to cause breakage after long-term use. At the same time, the connection method between the boom and the boom is relatively simple. It is very dangerous when the type ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a tower type lifting device that can effectively bolt the anchor boom to solve the problem that the connection between the main parts of the current tower type lifting device proposed by the above-mentioned background technology is relatively simple, and there are certain potential safety hazards , at the same time, the exhaust effect of the boom is poor, and it is easy to shake when it is blown by the wind.
