Apparatus for supporting telescopic boom for mounting crane to construct pillar of tower shaped structure and method for constructing pillar

Abstract

The present invention provides an apparatus for supporting a telescopic boom for mounting a crane to construction a pillar of a tower shaped structure and a method for constructing the pillar. For the telescopic boom for mounting the crane to construct high-rise tower shaped structure such as pillar and tower frame, through successively supporting the telescopic boom on stacked pillar components, the telescopic boom can be used for stably constructing higher pillars. A pillar receiving base is equipped on a mounting base through a free advancing / retreating mode. The mounting base is fixed on each boom of the telescopic boom and is provided with a pair of holding arms. The holding arms hold the pillar components between a holding position on the pillar receiving base and a releasing position through a swingable mode. A roller chain is configured at inside part of the holding arms through a mode that the diameter of the roller chain can be reduced and the roller chain can be connected with the holding arms. The pillar receiving base advances and pushes the pillar component. The holding arms hold the pillar component. When a chain opening / closing cylinder operates and the roller chain is pulled for reducing the diameter, the roller chain fastens the pillar components for supporting the booms on the pillar component.

Description

technical field [0001] The present invention relates to a support device for a telescopic boom that supports a telescopic boom on a pillar to be constructed and a construction method for the pillar using a construction crane mounted on the telescopic boom supported by the support device. The arm is used to mount the above-mentioned construction crane on the front end to raise and lower the construction crane to the top of the tower structure, and to construct a high place that extends to the sky like a pillar, tower, monument, etc. on the ground. For tower structures, the construction cranes mentioned above are used. Background technique [0002] There are various structures such as towers, monuments, and chimneys as tower-like structures built on the ground, and one of them is a windmill tower used as a pillar of a windmill for wind power generation. On the top of the windmill tower, there are a plurality of propeller blades (blades) supported by horizontal shafts, and a n...

Problems solved by technology

When the operator performs the connection work of the above-mentioned connection members, a crane or the like is required to lift the operator up, and the crane must be carried to the construction site, which increases the number of heavy equipment for construction and may complicate the construction work.
