Description

Technical Field

[0001] The present application relates to the technical field of electric power construction, and in particular to an electric power pipe cutter for electric power construction. Background Art

[0002] Power construction is a project for the transmission and distribution of electric energy. Electric energy has many advantages such as easy conversion, convenient transportation, easy control, easy use, clean and economical. During power construction, power pipes are needed to connect and transmit power lines for easy installation and use. Power pipes are products that are hot-dip-coated with PE (modified polyethylene) or coated with epoxy resin inside and outside. They have excellent corrosion resistance. At the same time, because the coating itself has good electrical insulation, it will not produce electrical corrosion, has low water absorption, high mechanical strength, and low friction coefficient, and can achieve the purpose of long-term use. When laying power pipes, it is necessary to cut the power pipes according to the terrain and specific conditions of the laying, so on-site cutting is often used, and power pipe cutters are common processing equipment.

[0003] However, the existing power pipe cutter still has some defects during use: first, during power construction, the size of the power pipe needs to be cut according to demand. Due to the large diameter of the power pipe, it is impossible to cut it at one time, and the existing power pipe cutting is all carried out outdoors, and it is impossible to use large cutting equipment for cutting. The usual method is to use a small cutting equipment to make multiple cuts around the pipe wall of the power pipe, so that the power pipe is cut off. However, due to the need for multiple cuts, the initial cutting position of each cut will have a certain deviation from the last cutting position, resulting in an uneven cut end face of the power pipe with burrs, so that the end face of the power pipe needs to be polished later, which reduces the cutting efficiency and increases the labor of the construction workers. Secondly, during power construction, a specific length of power pipe is often required, but it is difficult for the power pipe cutter to measure the length of the power pipe when cutting the power pipe, resulting in a large error in the length of the cut power pipe, affecting the construction process. Summary of the invention

[0066] The working principle of the method of the present invention is as follows:

[0067] When the electric pipe fitting 1 needs to be cut, the combined cutting component 2 and the fixing component 3 are firstly movably connected with the electric pipe fitting 1 in sequence, that is, the cutting component 2 is movably connected with the electric pipe fitting 1 through the first through hole 20, and the fixing component 3 is movably connected with the electric pipe fitting 1 through the second through hole 30. Then, the staff pulls a fixing component 3 to separate it from the cutting component 2, and the fixing component 3 is moved to a position at one end of the electric pipe fitting 1, and then the moving part 6 is rotated to realize the clamping and fixing of the fixing component 3 to the electric pipe fitting 1. Then, the staff moves the cutting component 2 and adjusts the fixing component 3 according to the tape measure 5. 4 is pulled out to determine the distance between the cutting component 2 and the fixing component 3. When the distance is equal to the length of the power pipe 1 to be cut, the movement of the cutting component 2 is stopped and the cutting component 2 is fixed at this position. Then another fixing component 3 is pulled out and an equal distance is pulled. Then the moving component 6 is used to fix the power pipe 1, thereby effectively ensuring the stability of the state of the power pipe 1 when it is located in the cutting component 2. Then the cutting component 4 is started to rotate the cutting wheel 41. Then the staff holds the cutting handle 43 and rotates the cutting wheel 41 in the self-rotating state along the outer groove 23 for one circle. The one-time stable cutting of the wall of the electric power pipe fitting 1 is realized, so there is no need to perform multiple cuttings around the wall of the electric power pipe fitting 1, and the initial knife position of each cutting will not deviate from the knife position of the last cutting, which effectively prevents the problems of unevenness and burrs on the cut end surface of the electric power pipe, thereby enhancing the cutting quality of the electric power pipe fitting 1 by the cutting component 2 and improving the cutting efficiency. After the cutting of the electric power pipe fitting 1 is completed, the staff rotates the winding handle 51 to realize the winding of the soft ruler 54, and at the same time combines the cutting component 2 and the fixing component 3 to improve the portability of the device. If it is necessary to cut equal lengths of electric power pipe fittings, the staff can use the winding handle 51 to wind up the soft ruler 54. When cutting the electric pipe fitting 1, since an ink strip is provided on the movable plate 62, the position of the last fixing component 3 on the electric pipe fitting 1 will be marked when the movable component 6 clamps the electric pipe fitting 1. At this time, the cutting component 2 only needs to be moved and aligned with the mark, and then the corresponding positions of the two fixing components 3 are adjusted to obtain an electric pipe fitting 1 of the same length as the previous electric pipe fitting 1. If electric pipe fittings 1 of different lengths need to be cut, the distance between the cutting component 2 and the fixing component 3 needs to be changed to adjust the length of the electric pipe fitting 1, thereby improving the cutting accuracy of the electric pipe cutter and effectively improving the construction process.
