Abstract

The invention discloses a device for combining and splitting a split cutting machine, and belongs to the field of pipeline cutting. The device comprises a left transmission mechanism, a right transmission mechanism and a force applying mechanism, wherein one end parts of the left transmission mechanism and the right transmission mechanism are respectively fixed to a left segment fixed ring and a right segment fixed ring of the split cutting machine; and the force applying mechanism is connected with the other end parts of the left transmission mechanism and the right transmission mechanism, and is used for driving the left transmission mechanism and the right transmission mechanism to move in the opposite directions or move in the backward directions to drive the split cutting machine to be split or combined. According to the device, the split cutting machine can be combined and split with time and effort saved, and safety is high.

Description

technical field [0001] The invention relates to the field of pipe cutting, in particular to a device for folding and splitting a split cutting machine. Background technique [0002] Split-type cutting machine, also known as split-type cold cutting machine or split-type cutting beveling machine, is often used in the construction of long-distance oil and gas pipelines and the repairing process of in-service pipelines, using safe cold cutting technology to cut and pipe steel pipes End bevel is of great significance for improving construction efficiency and quality. The split cutting machine mainly includes a mechanical system and a hydraulic system, and the mechanical system includes a split fixed ring, a rotating ring, a knife holder, a knife feed mechanism, and a clamping mechanism. The left lobe fixed ring and the right lobe fixed ring of the ring are opened and installed, and then connected and closed into a whole through a half-turn lock nut, and then fixed to the pipe wa...
