Pipeline interior cutting device

Abstract

The invention discloses a pipeline interior cutting device. The device comprises a cutting box of a regular triangle structure, cutter outlets are formed at the three top ends of the cutting box correspondingly, fixing plates are fixedly connected to the inner walls of the two sides of each cutter outlet correspondingly, and dense bristles are fixedly connected to the opposite sides of the two fixing plates correspondingly. Sliding grooves are formed at the positions of three angular bisectors of the inner walls of the two sides of the cutting box correspondingly, sliding blocks are slidably connected into the sliding grooves, and the sides, away from the sliding grooves, of the sliding blocks in every two opposite sliding grooves are jointly and fixedly connected with a mounting plate. The pipeline interior cutting device has the advantages that before cutting operation, a cutting tool is located in the cutting box all the time, then the device can be smoothly fed into a pipeline, theposition clamping phenomenon is avoided, the protection performance on the cutting tool is good, and the safety of the device is higher; and through cross powering on of a first electromagnet and a second electromagnet, adjustment of the cutting tool and conversion of cutting work are conducted, and workers can conveniently conduct cutting work in the pipeline.

Description

technical field [0001] The invention relates to the technical field of pipe cutting, in particular to a pipe internal cutting device. Background technique [0002] Circular pipes are the most common fluid transportation channels in daily life. With the increase in use, damage to pipes of various diameters will inevitably occur, and the first part of the maintenance process is to cut the pipes. In real life In order to seal off a pipe, it is often necessary to cut the pipe, whether underground or above ground, from the inside. [0003] With some cutting devices in the prior art, when cutting the inner wall of the pipeline, it is often difficult to send the cutting knife into the pipeline smoothly because the cutting belt knife is too large, or when cutting the pipeline, the cutting knife is damaged due to the high hardness of the pipeline. The problem that the cutter head is easily damaged makes it difficult for the staff to cut the inside of the pipeline. [0004] To solve...
