Title:
CONCRETE SURFACE CUTTING APPARATUS CAPABLE OF AUTOMATICALLY ADJUSTING DIRECTION
Document Type and Number:
WIPO Patent Application WO/2022/124713
Kind Code:
A1
Abstract:
The present invention relates to a concrete surface cutting apparatus capable of automatically adjusting the direction thereof, the concrete surface cutting apparatus comprising: a mounting part for mounting on heavy equipment; and a drum header including a bit drum which is connected to the mounting part and is rotatable by a hydraulic motor, wherein an angle adjusting tool is coupled between the mounting part and the drum header. The angle adjusting tool comprises: an outer rotation coupling plate coupled to the mounting part via a bolt; an inner ring separation preventing tool coupled to one side surface of the outer rotation coupling plate; and an inner rotation coupling tool which is formed between the outer rotation coupling plate and the inner ring separation preventing tool and is coupled to the drum header via an angle adjusting tool coupling bolt. The present invention has the effects of reducing the working time and labor intensity of a worker, to thereby improve working efficiency, because, even when a concrete surface is inclined like a slope or inner wall of a tunnel, the worker does not need to separate the bit drum from the heavy equipment and adjust the angle of the bit drum according to the inclination angle of the working site, and the worker only needs to allow the bit drum to come into close contact with the working surface, and then, while the drum header itself is rotated, the angle can be adjusted by the angle adjusting tool according to the inclination angle of the working surface.
