Abstract

The invention belongs to the technical field of hole boring, and particularly relates to a hole boring machine for tower crane lug plates. The hole boring machine comprises a hole boring device and apositioning device. The positioning device comprises a guide rod, a first positioning plate and a second positioning plate. A positioning column is embedded in the first positioning plate. Through thedesign of the detachable positioning plates and the action of the positioning column, the requirement for boring holes in the lug plates of different specifications on a tower crane can be met; meanwhile, under the connecting action of a guide frame, through a rocking bar on the guide frame, the hole boring device can move along the guide rod to bore holes in the lug plates; due to the design, the hole boring machine is convenient to install and detach and easy to operate; and meanwhile, due to the design of the guide rod, a motor installing base and a handle, when hole boring is performed aloft, operation can be carried out by a single person, the aloft operation risk generated by cooperation of multiple persons is reduced, and the connectivity of all connecting piece abraded lug platesof the tower crane can be conveniently restored.

Description

technical field [0001] The invention belongs to the technical field of boring, and in particular relates to a tower crane lug plate boring machine. Background technique [0002] Tower crane, the abbreviation of tower crane, is an indispensable construction machinery in the construction site. In high-rise construction such as real estate buildings, tower crane operation is a necessary lifting equipment. Its installation, disassembly and use are safe It is the most important thing related to the safe production of project construction. As a typical steel structure equipment, tower cranes are installed, dismantled and used. The connection methods such as ear plates, pins, and bolts are the most common connection methods, and tower cranes are in use. It is necessary to adjust the height according to the construction progress and strength of the project, and after the installation of a tower crane, the use time varies according to the progress of the project, ranging from one to ...
