Description

Technical Field

[0001] This utility model relates to the field of power construction technology, and in particular to a power pipe cutter for power construction. Background Technology

[0002] Electrical conduits are pipe systems used to protect, lay, and conceal electrical cables. They are typically made of plastic and possess properties such as insulation, corrosion resistance, pressure resistance, and moisture resistance. They are suitable for cable burial in urban power grids, building construction, and transportation facilities. Electrical conduits standardize wiring, prevent cable damage, improve safety and aesthetics, and facilitate future maintenance and expansion, making them an important component of modern power infrastructure. Installation must adhere to relevant standards to ensure conduit sealing and grounding safety.

[0003] During actual construction, workers need to cut electrical conduits to the required length. A common cutting tool is a guillotine cutter. While effective at cutting conduits, the guillotine blade cuts from one side to the other, resulting in constant unilateral stress on the conduit. During cutting, the guillotine continuously compresses the conduit's side in the same direction. This continuous compression can cause deformations invisible to the naked eye, leading to tiny, unseen cracks in certain areas and ultimately affecting the conduit's lifespan. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A power pipe cutter for power construction includes: a collar 1, a support roller 2, a cutting disc 3, and a spring 4. The collar 1 has an opening 11. The collar 1 is fitted onto the power pipe to be cut through the opening 11. The support roller 2 is rotatably connected to the collar 1 and protrudes from the inner wall of the collar 1. The cutting disc 3 is connected to the collar 1. One end of the spring 4 is connected to the cutting disc 3, and the other end is connected to the collar 1, to push the cutting disc 3 towards the center of the collar 1.

[0020] In practical applications, the collar 1 is placed on the power pipe to be cut. The position of the collar 1 is adjusted so that it is positioned for cutting. At this time, the support roller 2 is in contact with the power pipe, the inner wall of the collar 1 is in contact with the power pipe, and the cutting disc 3 is in contact with the power pipe. Simultaneously, under the pushing force of the spring 4, the cutting disc 3 cuts into the power pipe. Subsequently, the collar 1 is rotated, and driven by the collar 1, the cutting disc 3 moves along the circumference of the power pipe, thereby performing a circumferential cut. As the collar 1 continues to rotate and under the elastic force of the spring 4, the cutting depth of the cutting disc 3 gradually increases, and finally, the cutting disc 3 cuts the power pipe. In summary, the contact area between this utility model and the power pipe includes at least three areas: the support roller 2, the collar 1, and the cutting disc 3. Furthermore, this utility model uses a circumferential cutting method for cutting, rather than cutting from one side to the other. This results in a more uniform stress distribution on the power pipe during the cutting process, keeping the deformation of the power pipe within an acceptable range and minimizing damage. Preferably, when adjusting the position of the adjusting collar 1 on the power pipe, a metal shim can be placed between the cutting disc 3 and the power pipe beforehand to prevent the cutting disc 3 from scratching the power pipe when adjusting the adjusting collar 1.

[0021] The collar 1 also includes a swing rod 12, an adjustment structure 13, and a sleeve 14. There are two swing rods 12. One end of each swing rod 12 is oscillatingly connected to the collar 1. One swing rod 12 is connected to the support roller 2, and the other swing rod 12 is connected to the cutting disc 3. The two swing rods 12 are symmetrically arranged about the center of the collar 1. The collar 1 also includes an adjustment structure 13. The adjustment structure 13 includes a swing base 131 and an adjusting bolt 132. The swing base 131 is composed of two interconnected plates that can rotate relative to each other. Each swing base 131 corresponds to one swing rod 12. The swing base 131 is fixedly connected to the swing rod 12. The adjusting bolt 132 and a spring 4 pass through the collar 1. One adjusting bolt 132 extends into one swing base 131, and the spring 4 extends into the other swing base 131. The sleeve 14 is fixedly connected to the collar 1. A guide rod 141 is slidably disposed inside the sleeve 14. The guide rod 141 is sleeved on the spring 4. Another adjusting bolt 132 is screwed into the sleeve 14, and one end of the adjusting bolt 132 abuts against the guide rod 141.

[0022] In practice, the collar 1 and sleeve 14 are provided with threads corresponding to the adjusting bolt 132, while the inner wall of the swing base 131 is smooth. Therefore, the rotation of the adjusting bolt 132 only maintains the abutment state of the swing base 131. When the diameter of the power pipe to be cut is smaller than the inner diameter of the collar 1, rotating the adjusting bolt 132 causes it to gradually extend into the collar 1 under the action of the threads. This pushes the swing rod 12 through the swing base 131, causing the swing rod 12 to swing towards the center of the collar 1. Consequently, the support roller 2 gradually approaches the power pipe and eventually comes into contact with the outer wall of the power pipe. During the swinging process of the swing rod 12, the angle between the swing rod 12 and the adjusting bolt 132 gradually changes, and the swing base 131 performs corresponding actions to ensure the aforementioned process proceeds normally. Simultaneously, rotating the other adjusting bolt 132 causes it to slide relative to the sleeve 14, thereby gradually extending into the sleeve 14. During the movement of the adjusting bolt 132, it pushes the guide rod 141 to slide, which in turn pushes the corresponding swing rod 12 to swing via the spring 4, allowing the cutting disc 3 to fit against the power pipe. Therefore, this invention can effectively adapt to power pipes of different diameters. Furthermore, during the cutting process, the operator can rotate the adjusting bolt 132 according to the cutting status to make timely adjustments. Thus, the aforementioned structure facilitates practical operation for the operator.

[0023] It also includes an operating handle 5. An operating ring 51 is provided on the operating handle 5. The operating handle 5 is fixedly connected to the operating ring 51. The operating ring 51 is connected to a collar 1. A ratchet 15 is fixedly provided on one side of the collar 1. The operating ring 51 is rotatably fastened to the ratchet 15. A ratchet tooth 511 is provided inside the operating ring 51. The ratchet tooth 511 corresponds to the ratchet 15. A rotating ring 16 is also fixedly provided on one side of the collar 1. The rotating ring 16 extends into the operating ring 51.

[0024] In practical applications, operators can manipulate the collar 1 by cranking the operating handle 5. Driven by the ratchet 15 and ratchet teeth 511, pushing the operating handle 5 causes the collar 51 to move relative to the ratchet 15. At this time, the collar 1 remains stationary. Pulling the operating handle 5 engages the ratchet teeth 511 with the ratchet 15. The operating handle 5 then drives the collar 1 to rotate via the ratchet teeth 511 and the ratchet 15. Thus, by repeatedly pushing and pulling the operating handle 5, the operator can make the collar 1 rotate continuously in the same direction, thereby completing the aforementioned cutting process. In summary, the operating handle 5 greatly facilitates the operator's actual operation, allowing them to cut the power pipe within a relatively small workspace. Furthermore, the operating handle 5 makes it easier for the operator to apply force to the collar 1, further simplifying the operation.
