Abstract

The invention provides a stable lifting and conveying type tower crane. The tower crane comprises a base, a tower body, a rotary platform, a tower top, a lifting arm, a balance arm and a lifting mechanism. The lifting mechanism comprises a guide wire box, a first positioning wheel set, a second positioning wheel set, a guide wire wheel, a drawn wire, a wire winding device and a first object hanging device. The upper end of the guide wire box is provided with a wire inlet hole and a wire outlet hole. The first positioning wheel set comprises two first rolling wheels which can be rotationally installed in the guide wire box. The second positioning wheel set comprises two second rolling wheels which can be rotationally installed in the guide wire box. The first object hanging device comprises a first hook, a limiting frame, a semi-annular clamping part, a moving shaft and a rotating shaft. The first hook is provided with an object clamping opening. The moving shaft vertically penetrates through the first hook and the limiting frame and is connected with the limiting frame through a reposition key. The periphery of the rotating shaft is provided with a first tooth groove. The moving shaft and the semi-annular clamping part are provided with a second tooth groove and a third tooth groove correspondingly. The stable lifting and conveying type tower crane is convenient to use and stable in structure.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a hoisting and stable tower crane. Background technique [0002] Tower crane (towercrane) referred to as tower crane, also known as tower crane, 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 tower body, jib and base etc. When lifting heavy objects by tower cranes, the heavy objects are generally bound by ropes, etc., and then hung on the ropes by hooks for lifting, but the safety of current tower cranes is not high enough. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present inventi...
