[0002] 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 and good electrical insulation, and can effectively prevent damage to plant roots and soil environmental stress. After production, power pipes are usually a long pipe that needs to be cut to the required length.

[0003] Chinese patent CN 218802599U discloses a convenient cutting device for electric power pipelines in power construction, including a support seat, a placement plate, a fixing frame, a support rod, a torsion spring and a fixing rod, etc. The support seats are symmetrically arranged on the left and right sides of the bottom of the placement plate, and a fixing frame is arranged on the left front of the top of the placement plate. A support rod is arranged inside the fixing frame, and a fixing rod is rotatably arranged on the support rod. Torsion springs that can be used for resetting are connected between the left and right side walls of the fixing rod and the fixing frame, and the pipe can be clamped by a clamping block to prevent the cutting pipe from being misaligned. However, after completing the cutting of a section of the pipe, the remaining longer pipe needs to be manually re-clamped and the cutting length confirmed, which reduces the cutting efficiency of the pipe.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, other implementation methods or equivalent replacements obtained by those skilled in the art without creative work are all within the scope of protection of the utility model.

[0024] like Figure 1-7 As shown, a power pipeline cutting device includes, from left to right, a conveying frame 1, a cutting frame 2 and a material unloading frame 3; the conveying frame 1 is slidably connected to a support frame 4, a support ring 5 is fixedly connected to the top of the support frame 4, and the support ring 5 is installed with evenly distributed auxiliary electric telescopic arms 6, and a buffer pad can be installed on the abutting surface of the auxiliary electric telescopic arms 6 and the long power pipeline 10 to prevent indentations from being left on the surface of the long power pipeline 10, and the conveying frame 1 is installed with symmetrical main horizontal electric telescopic arms 7, and the main horizontal electric telescopic arms 7 are fixedly connected to auxiliary horizontal electric telescopic arms 8, and the auxiliary horizontal electric telescopic arms 8 are fixedly connected to clamping plates 9;

[0025] The auxiliary electric telescopic arm 6 and the clamping plate 9 are respectively in contact with the long power pipeline 10, the main horizontal electric telescopic arm 7 is extended, and the clamping plate 9 pushes the long power pipeline 10 to move in the direction of the cutting frame 2; the auxiliary horizontal electric telescopic arm 8 is retracted, the clamping plate 9 is separated from the long power pipeline 10, the main horizontal electric telescopic arm 7 is retracted, the auxiliary horizontal electric telescopic arm 8 is extended, and the clamping plate 9 is in contact with the long power pipeline 10 again; the main horizontal electric telescopic arm 7 is extended again, and the long power pipeline 10 moves again; the length of the main horizontal electric telescopic arm 7 extended twice is the length of the power pipeline of the required specification;

[0026] When the auxiliary horizontal electric telescopic arm 8 is in the retracted state, the space between the two clamping plates 9 can allow the auxiliary electric telescopic arm 6 to pass normally;

[0027] The cutting frame 2 is equipped with an upper vertical electric telescopic arm 11 and a lower vertical electric telescopic arm 12. The bottom end of the upper vertical electric telescopic arm 11 is fixedly connected with a cutting knife 13, and the top end of the lower vertical electric telescopic arm 12 is fixedly connected with a support platform 14.

During the sliding operation of the support frame 4, the clamping plate 9 is prevented from being aligned with the support ring 5 so that the clamping plate 9 cannot clamp the long power pipeline 10.

[0029] Among them, the cutting frame 2 is fixedly connected to the top frame, and the top frame is connected to the wire of the auxiliary electric telescopic arm 6 through the spring coil 16. By tightening or stretching the spring coil 16, the wire of the auxiliary electric telescopic arm 6 can adapt to the movement of the auxiliary electric telescopic arm 6, and the wires (not shown) of the main horizontal electric telescopic arm 7, the secondary horizontal electric telescopic arm 8, the upper vertical electric telescopic arm 11 and the lower vertical electric telescopic arm 12 are in a relatively stable state.
