Problems solved by technology

[0002] When installing pipelines in sewage wells, due to the narrow space inside the sewage wells, a hand-held cutting machine is used to cut the pipelines. The cutting knife rotates at high speed to cut the pipelines. At the same time, the cutting machine is equipped with a clamping block, which can clamp the pipelines. The clamping block is provided with a rotating ring, and the rotating ring cooperates with the pipe to make the cutting machine rotate around the outside of the pipe to cut the pipe. The mud sticks to the outer wall of the pipe with the flow of sewage. When the rotating ring contacts the outer wall of the pipe, the sludge will stick to the outer wall of the rotating ring and solidify, causing the surface of the outer wall of the rotating ring to be uneven. When cutting different pipes again, the rotating ring will The friction with the outer wall of the pipe increases, and the cutting machine rotates around the outer wall of the pipe to slow down, further slowing down the cutting speed of the cutting machine on the pipe

Abstract

The invention discloses pipeline cutting equipment based on a narrow space. The structure of the pipeline cutting equipment comprises a machine body, a cutting knife and a clamping block. Sludge reversely adheres to the outer wall of a rotating ring and is solidified, consequently, the surface of the outer wall of the rotating ring is uneven, a removing rod in a removing mechanism is movably matched with the rotating ring, the sludge on the outer wall of the rotating ring is removed by a removing block in a removing ring, so that the sludge left on the outer wall of the rotating ring can be reduced, the friction between the rotating ring and the outer wall of a pipeline is reduced, the rotating speed of a cutting machine around the outer wall of the pipeline is increased, and the cutting speed of the cutting machine to the pipeline is further increased; and since the sludge is left on the outer wall of the removing ring, when the removing ring is in contact with the rotating ring, sludge on the outer wall of the removing ring easily reversely adheres to the outer wall of the rotating ring, the sludge on the outer wall of the removing ring is removed through a push rod in a contact ring, the outer wall of the removing ring can be kept clean, sludge left on the outer wall of the removing ring is reduced, and sludge on the outer wall of the removing ring is prevented from reversely adhering to the outer wall of the rotating ring.
