DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 - Figure 4 ,in, Figure 1 It is a schematic diagram of the overall structure of the utility model; Figure 2 For this utility model Figure 1 The enlarged structural diagram at A in the middle; Figure 3 This is a cross-sectional view of a fixed U-shaped frame of the utility model; Figure 4 For this utility model Figure 3 The schematic diagram of the structure is enlarged at B. The electric power pipe cutter for electric power construction comprises: a mounting bracket 1, a threaded rod 2 is connected to the inner thread of the mounting bracket 1, a handle 3 is fixedly installed on the top of the threaded rod 2, a clamping plate 4 is rotatably connected to the lower end of the threaded rod 2, and a groove 5 is opened inside the mounting bracket 1.

[0025] In this method, when fixing the power pipe, the power pipe is placed into the groove 5 from the opening on one side of the mounting bracket 1, and then the handle 3 is rotated to move the threaded rod 2 downward inside the mounting bracket 1, and then the clamp 4 is moved downward, and then the clamp 4 clamps the power pipe, so that it is convenient to install the mounting bracket 1 on the power pipe, improve the convenience of installation of the device, facilitate installation at any position of the power pipe, and reduce the difficulty of installation operation.

[0026] In the above method, a connecting bracket 6 is fixedly installed on one side of the mounting bracket 1, and the internal rotation of the connecting bracket 6 is connected to the rotating shaft 14. The bottom of the rotating shaft 14 is fixedly installed with a connecting frame 16, and the internal sliding connection of the connecting frame 16 is two sliding blocks 17, and the two sliding blocks 17 are both T-shaped. The bottoms of the two sliding blocks 17 are respectively fixedly connected with a first positioning semi-ring 11 and a second positioning semi-ring 13, and the first positioning semi-ring 11 and the second positioning semi-ring 13 form a circular ring. The first positioning semi-ring 11 and the limiting slide 12 are both provided with a limiting slide 12, and the internal sliding connection of the limiting slide 12 is connected with a sliding frame 7, and the internal sliding connection of the sliding frame 7 is connected with a hanging frame 9, and the internal thread connection of the sliding frame 7 is connected with a lifting adjustment threaded rod 8, and the interior of the hanging frame 9 is threadedly connected to the surface of the lifting adjustment threaded rod 8, and the interior of the hanging frame 9 is fixedly installed with a cutting blade 10.

[0027] In this method, when cutting the power pipe, the second positioning half ring 13 and the first positioning half ring 11 are put on the power pipe, and then the lifting and adjusting threaded rod 8 is rotated to move the suspension frame 9 downward, so that the cutting blade 10 contacts the surface of the power pipe, and then the sliding frame 7 rotates around the limiting slide 12, and then the power pipe is cut by the cutting blade 10, which facilitates the cutting of the pipeline.

[0028] In the above manner, the internal thread of the connecting bracket 6 is connected with a bolt 15 , and one end of the bolt 15 extending to the inside of the connecting bracket 6 contacts the surface of the rotating shaft 14 .

[0029] In this method, the bolt 15 is rotated to move outward inside the connecting bracket 6, so that one end of the bolt 15 no longer contacts the surface of the rotating shaft 14, and then the rotating shaft 14 is rotated to rotate the second positioning half ring 13 and the first positioning half ring 11. After adjusting the angle of the second positioning half ring 13 and the first positioning half ring 11, the bolt 15 is rotated in the opposite direction to move the bolt 15 toward the inside of the connecting bracket 6, so that the bolt 15 contacts the surface of the rotating shaft 14, thereby fixing the rotating shaft 14, facilitating the fixing of the angle of the second positioning half ring 13 and the first positioning half ring 11, and facilitating the adjustment of the angle of the first positioning half ring 11 and the second positioning half ring 13, so as to facilitate the adjustment according to the cutting requirements and facilitate multi-angle cutting.

[0030] In the above manner, a limiting rod 19 is fixedly installed on one side of the connecting frame 16. The limiting rod 19 is polygonal in shape. A fixed U-shaped frame 18 is slidably connected to the surface of the limiting rod 19. The fixed U-shaped frame 18 is slidably connected to both sides of the connecting frame 16. A return spring 20 is movably sleeved on the surface of the limiting rod 19. One end of the return spring 20 close to the fixed U-shaped frame 18 is fixedly connected to the fixed U-shaped frame 18, and one end of the return spring 20 away from the fixed U-shaped frame 18 is fixedly connected to the limiting rod 19.

[0031] In this method, the fixed U-shaped frame 18 is pushed to move the fixed U-shaped frame 18 on the surface of the limiting rod 19. Since the fixed U-shaped frame 18 is in a polygonal shape, it is convenient to move the fixed U-shaped frame 18 horizontally on the surface of the limiting rod 19, so that the fixed U-shaped frame 18 squeezes the return spring 20, so that the fixed U-shaped frame 18 no longer blocks the two ends of the connecting frame 16, and then the two sliding blocks 17 are taken out from the inside of the connecting frame 16, and then the second positioning half ring 13 and the first positioning half ring 11 are disassembled. When assembling, the two sliding blocks 17 are installed To the inside of the connecting frame 16, and at the same time, the first positioning half ring 11 and the second positioning half ring 13 are sleeved on the surface of the power pipe, and then the fixed U-shaped frame 18 is no longer squeezed, and the fixed U-shaped frame 18 is reset by the elastic force of the reset spring 20, so that the fixed U-shaped frame 18 blocks the two ends of the connecting frame 16, and then completes the fixation of the two sliding blocks 17, so that the first positioning half ring 11 and the second positioning half ring 13 are sleeved on the power pipe, thereby improving the convenience of device installation, avoiding the need to install from one end of the power pipe, improving the convenience of device operation, and thus reducing installation time.

[0032] The working principle of the power construction power pipe cutter provided by the utility model is as follows: the power pipe is placed into the interior of the groove 5 from the opening on one side of the mounting bracket 1, and then the handle 3 is rotated to move the threaded rod 2 downward inside the mounting bracket 1, and then the clamping plate 4 is moved downward, and then the clamping plate 4 clamps the power pipe, thereby facilitating the installation of the mounting bracket 1 on the power pipe.

[0033] The second positioning half ring 13 and the first positioning half ring 11 are put on the power pipe, and then the lifting and adjusting threaded rod 8 is rotated to move the suspension frame 9 downward, so that the cutting blade 10 contacts the surface of the power pipe, and then the sliding frame 7 rotates around the limiting slide 12, and then the power pipe is cut by the cutting blade 10, so as to facilitate the cutting of the pipeline.

[0034] Rotate the bolt 15 to move it outward inside the connecting bracket 6, so that one end of the bolt 15 no longer contacts the surface of the rotating shaft 14, and then rotate the rotating shaft 14 to rotate the second positioning half ring 13 and the first positioning half ring 11. After adjusting the angle between the second positioning half ring 13 and the first positioning half ring 11, rotate the bolt 15 in the opposite direction to move it toward the inside of the connecting bracket 6, so that the bolt 15 contacts the surface of the rotating shaft 14, thereby fixing the rotating shaft 14 and facilitating fixing the angle between the second positioning half ring 13 and the first positioning half ring 11.

[0035] The fixed U-shaped frame 18 is pushed to move the fixed U-shaped frame 18 on the surface of the limiting rod 19. Since the shape of the fixed U-shaped frame 18 is a polygon, it is convenient to make the fixed U-shaped frame 18 move horizontally on the surface of the limiting rod 19, so that the fixed U-shaped frame 18 squeezes the reset spring 20, so that the fixed U-shaped frame 18 no longer blocks the two ends of the connecting frame 16, and then the two sliding blocks 17 are taken out from the inside of the connecting frame 16, and then the second positioning semi-ring 13 and the first positioning semi-ring 11 are disassembled. When assembling, the two sliding blocks 17 are installed inside the connecting frame 16, and the first positioning semi-ring 11 and the second positioning semi-ring 13 are sleeved on the surface of the power tube, and then the fixed U-shaped frame 18 is no longer squeezed, and the fixed U-shaped frame 18 is reset by the elastic force of the reset spring 20, so that the fixed U-shaped frame 18 blocks the two ends of the connecting frame 16, and then the fixation of the two sliding blocks 17 is completed.
