Abstract

The invention discloses a tower crane used for a high-stability pipe. The tower crane used for the high-stability pipe comprises a tower body, wherein a rotating table is arranged at the upper end ofthe tower body, a tower top is arranged at the upper end of the rotating table, a balance arm and a cargo boom are oppositely arranged on the two sides of the tower top, a jack mechanism is movably installed on the cargo boom, the jack mechanism comprises a jack box, a winding roller and a first driving device which drives the winding roller to rotate are arranged in the jack box, a pull wire is installed on the winding roller, a pipe clamping mechanism is fixedly connected with an end portion of the pull wire, the pipe clamping mechanism comprises a positioning head connected with the pull wire, clamping devices are arranged on the positioning head, the clamping devices comprise telescoping parts and lifting hooks, the lifting hooks comprise connection heads, first lifting jaws and secondlifting jaws, and the upper ends of the first lifting jaws and the second lifting jaws extend to the upper ends of the connection heads, and are hinged to the lower ends of the telescoping parts separately. By means of the tower crane used for the high-stability pipe, the pipe is fixed, and not only is clamping very convenient, but also clamping is stable.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a tower crane for high-stability pipes. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Tower crane, referred to as tower crane for short, is a rotating crane whose boom is installed on the upper part of a tall tower. The function space is large, and it is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. [0003] In existing tower cranes, the heavy objects are generally fixed on the ho...
