Description

Pile cutting machine with protection function for constructional engineering Technical Field The utility model relates to the technical field of pile cutting machines, in particular to a pile cutting machine with a protection function for construction engineering. Background The pile cutting machine for the building engineering is mechanical equipment capable of guaranteeing construction safety and improving construction efficiency in pile cutting operation. The pile cutting machine moves to the position where pile cutting is needed through the travelling mechanism, and the equipment is adjusted to be stable. And starting a hydraulic system to drive the pile cutting tool to rotate or reciprocate. Meanwhile, the protection device is in a working state, so that construction safety is ensured. After the pile cutting tool is contacted with the concrete pile, the pile body is cut off by the cutting force of the tool. The cut pile body is cleaned and carried by constructors or auxiliary equipment. In the prior art, a pile cutting machine for building engineering as disclosed in publication number CN220150310U comprises a connecting ring, wherein a connecting hanging column is arranged at the top of the connecting ring in a rectangular shape, a hanging ring piece is arranged at the top of the connecting hanging column, and an electric telescopic rod is arranged at the bottom of the connecting ring in a rectangular shape.
