Description

Fire-fighting pipe cutting device for fire control Technical Field The invention relates to the technical field of fire-fighting equipment processing, in particular to a fire-fighting pipe cutting device for fire fighting. Background In the field of fire engineering, the processing and preparation of fire extinguishing pipelines are vital links. Fire extinguishing pipes (e.g., galvanized steel pipes, plastic coated composite pipes, etc.) typically require fixed length cutting according to installation layout and polishing of the cut pipe ends to remove burrs, rust or prepare for subsequent threaded, welded or flanged connections. At present, in the processing process of fire-fighting pipelines, the traditional cutting and polishing operations mostly adopt separated equipment or manual operation. For example, an operator first cuts a pipe to a fixed length using a grinding cutter or a metal band sawing machine, then transfers the cut pipe section to another station, and deburrs and bevels the inner and outer walls of the pipe end using a hand-held angle grinder or a bench grinder. The sectional processing mode has the following obvious defects: 1. cutting and polishing are completed on two different equipment or stations, so that the pipeline needs to be assembled, disassembled and transported for many times, the auxiliary operation time is increased, the production continuity is broken, the overall processing efficiency is low, and the requirement of large-scale production is difficult to meet. 2. After the pipeline is cut, the pipeline needs to be clamped again for polishing. The secondary clamping easily causes the positioning reference to change, so that the polished pipe end axis is deviated from the original pipe axis, the concentricity and the perpendicularity of the pipe ends are affected, the subsequent pipe connection installation is difficult, and even potential safety hazards such as leakage and the like are possibly caused by loose connection. 3. After the cutting is finished, the distance between two cutting surfaces is relatively short, and the traditional polishing tool is difficult to extend into the cutting surfaces to effectively work, so that burrs on the inner sides of the pipe ends are not thoroughly cleaned, the smoothness of the inner walls of the pipelines is affected, and the resistance of medium conveying is increased. Based on the above, the invention designs a fire-fighting pipe cutting device for fire protection, so as to solve the problems.
