Special independent arm head for wind electricity

Abstract

The invention relates to a special independent boom head for wind electricity. The special independent boom head for wind electricity comprises a lifting boom head assembly, a connecting frame assembly and a super pulling plate assembly, wherein the lifting boom head assembly comprises a trussed-type boom head, a guide rope pulley and a pulley block; the guide rope pulley and the pulley block are respectively installed on two end parts of the trussed-type boom head; the trussed-type boom head is connected with the connecting frame assembly; the connecting frame assembly is connected with a tail boom of the main lifting boom; the super pulling plate assembly is installed on the end part, where the guide rope pulley is arranged, on the trussed-type boom head; and the lifting boom head assembly and the connecting frame assembly are integrally installed and detached on the tail boom of the main lifting boom. According to the special independent boom head disclosed by the invention, the lifting boom head assembly and the connecting frame assembly which are integrally installed and detached act as a special independent boom head for the installation scene of a wind electricity machine unit; the independent boom head can be installed rapidly under the condition of increasing the shorter boom length; and moreover, the trussed-type boom head is adopted for the lifting boom head, the boom length is short; the wind resistance is low; the compression resistance and bending resistance are high.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an independent arm head dedicated to wind power. Background technique [0002] The jib is an essential part of the construction crane. The traditional jib is either not high enough or wide enough for wind power hoisting, or the height and width are sufficient but interferes with the head of the last jib, making it difficult to install and disassemble wind power. With the development and market demand of super-large tonnage cranes, different hoisting forms are required for different use environments and working conditions. [0003] In order to meet the needs of large-scale equipment installed at high places such as wind turbines, it is necessary to have strong lifting performance within a certain height and amplitude range, so an independent arm head structure with a pulley device is adopted, and it is installed on the last arm to meet heavy loads. lifting and hoisting.
