[0002] MPP power pipe is also called MPP power cable protection pipe and MPP cable protection pipe. It is divided into trenchable and trenchless types. MPP trenchless power pipe is also called MPP jacking pipe or dragging pipe. It has the characteristics of high temperature resistance and external pressure resistance. MPP power pipe uses modified polypropylene as the main raw material. It does not require a large amount of mud, excavation and damage to the road surface. It is a construction project for laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional "trench digging and pipe burying method", trenchless power pipe projects are more in line with current environmental protection requirements.

One end of the limiting groove 4 extends to the workbench 1. The limiting groove located on the workbench 1 passes through the workbench 1. A placement groove 7 is provided on the inner surface of the limiting groove 4 and located on the workbench 1. The placement groove 7 is symmetrically arranged with respect to the center line of the limiting groove. The other end of the spring 8 is fixedly connected to the bottom of the placement groove 7.

[0030] Working principle: When in use, put the MPP power pipe to be cut into the storage bin 2. Due to the effect of gravity, the MPP power pipe at the bottom will fall into the limit groove 4. Then, manually push the MPP power pipe in the limit groove 4 toward the workbench 1 until one end of it contacts the top cone 6. Then, energize the electromagnetic coil 10 to generate a magnetic field. The magnetic block 9 generates a thrust to move under the action of the magnetic field. Since the magnetic block 9 and the clamping block 13 are connected by a connecting piece, the clamping block 13 is driven to move to position and clamp the MPP power pipe. Then, the size of the cut is determined by using The moving mechanism 17 moves the position of the cutting mechanism 3, and then the MPP power tube is cut by using the cutting mechanism. After the cutting is completed, the electromagnetic coil 10 is powered off to make the magnetic field disappear, and the magnetic block 9 loses its thrust due to the loss of magnetic force. Subsequently, the spring 8 resets and contracts, driving the magnetic block 9 and the clamp 13 to move, thereby making the MPP power tube lose its limiting clamping effect. Since there is no top cone 6 to limit one end of the cut surface of the MPP power tube, it will fall first and contact the conveying mechanism 5. The cut MPP power tube will be collected as the conveying mechanism 5 moves forward.
