Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a power pipe cutting device. Background Technology

[0002] Electrical conduits are often cut using a rotary cutting method, which involves clamping the conduit and rotating the cutter to cut it. However, the guide wheels used to clamp the conduit and guide the cutter often lack a continuous, stable, and adjustable clamping force; this results in poor contact between the cutter and the conduit during the cutting process, unstable cutter trajectory, difficult cutting, and uneven cut surfaces. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a power pipe cutting device to solve the problem that the guide wheel and the surface of the power pipe are not tightly attached, making it difficult to accurately control and maintain a reliable clamping force.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A power pipe cutting device, comprising:

[0006] The fixed bracket is equipped with a first guide wheel;

[0007] The first movable bracket is slidably mounted on the fixed bracket and is equipped with a cutter;

[0008] The second movable bracket is rotatably mounted on the first movable bracket to form a cavity between itself and the fixed bracket that can accommodate the power tube, and the second movable bracket is provided with a second guide wheel;

[0009] as well as,

[0010] The support assembly includes a support column and a support wheel. The support column is movably disposed on the first movable bracket, and the support wheel is rotatably disposed on the second movable bracket. The support column moves relative to the first movable bracket under force, so that the support column abuts against the support wheel and keeps the second guide wheel in a state of contact with the surface of the power pipe.

[0011] Furthermore, the first movable bracket is provided with a threaded hole, and the support column is threadedly connected to the threaded hole.

[0012] Furthermore, the first movable bracket is provided with a clamp, which has a space for the fixed bracket to pass through and is used to clamp the outer periphery of the fixed bracket.

[0013] Furthermore, the first movable bracket has two clamps, and fasteners pass through the two clamps and the fixed bracket, fixing the first movable bracket to the fixed bracket.

[0014] Furthermore, the cutter is movably mounted on the first movable bracket to extend into or out of the cavity.

[0015] Furthermore, the first movable bracket is slidably provided with a sliding seat, which is connected to the cutter and threaded to the screw, so as to drive the cutter to move when subjected to force.

[0016] Furthermore, the second movable bracket is provided with an opening for avoiding the cutter.

[0017] Furthermore, the fixed bracket and / or the second movable bracket are provided with a notch, the notch having a V-shaped structure and being oriented towards the cavity.

[0018] Furthermore, both the fixed bracket and the first movable bracket are provided with handles, and the two handles are arranged opposite to each other.

[0019] Furthermore, the rotation angle of the second movable support is 0° to ±30°.

[0020] Compared with the prior art, this utility model has the following advantages: by sliding the first movable bracket, the second movable bracket is moved together, thereby adjusting the size of the cavity formed between the fixed bracket and the second movable bracket to clamp power pipes of different diameters; furthermore, the rotating second movable bracket can open and close the cavity, and when the support column is under force, the support column can hold the support wheel, forcing the second movable bracket to rotate around its rotation point, thereby continuously and stably pressing the second guide wheel against the surface of the power pipe; and with the basic support and positioning provided by the first guide wheel, it can ensure that the cutter moves stably in the trajectory formed by the guide wheel, so as to provide a stable clamping force, thereby avoiding cutting surface deviation or unevenness caused by poor contact.

[0027] The present invention will be further described in detail below through specific embodiments:

[0028] In the embodiments of this utility model, such as Figures 1-4 As shown, the power pipe cutting device includes: a fixed bracket 1, a first movable bracket 3, a second movable bracket 5, and a support assembly; the fixed bracket 1 is provided with a first guide wheel 2; the first movable bracket 3 is slidably disposed on the fixed bracket 1 and is provided with a cutter 4; the second movable bracket 5 is rotatably disposed on the first movable bracket 3 to form a cavity 6 between itself and the fixed bracket 1 for accommodating the power pipe, and the second movable bracket 5 is provided with a second guide wheel 7; the support assembly includes a support column 8 and a support wheel 9, the support column 8 is movably disposed on the first movable bracket 3, and the support wheel 9 is rotatably disposed on the second movable bracket 5. The support column 8 moves relative to the first movable bracket 3 under force, so that the support column 8 abuts against the support wheel 9, and the second guide wheel 7 is kept in contact with the surface of the power pipe.

[0029] Specifically, in this embodiment of the invention, the fixed bracket 1 is provided with a rotatable first guide wheel 2, which is used to rotate the first guide wheel 2 to fit against the surface of the power pipe. Additionally, the fixed bracket 1 extends a slide rail, which can slide and engage with the first movable bracket 3, allowing the first movable bracket 3 to move closer to or away from the fixed bracket 1. A cutting blade 4 is provided at the first movable bracket 3 for cutting the power pipe. Simultaneously, a second movable bracket 5 is rotatably mounted at the first movable bracket 3, and the second movable bracket 5 is provided with a second guide wheel 7, which forms a cavity 6 with the fixed bracket 1. This cavity 6 can accommodate power pipes of different diameters. Thus, the fixed bracket 1 serves as the foundation of this cutting device. It can first be installed on the upper surface of the power pipe, then the first movable bracket 3 is slid to a suitable position so that the first guide wheel 2 and the second guide wheel 7 can respectively fit against the opposite surfaces of the power pipe. Finally, the fixed bracket 1 and the first movable bracket 3 are continuously rotated so that the cutting blade 4 can move within the circular trajectory formed by the two guide wheels to cut the power pipe.

[0030] However, because the second movable bracket 5 and the first movable bracket 3 are rotatably connected to facilitate the opening and closing of cavity 6 and improve the versatility of this cutting device, the second guide wheel 7 may have poor contact with the surface of the power tube. Therefore, this embodiment provides a movable support column 8 in the first movable bracket 3 and a rotatable support wheel 9 in the second movable bracket 5. When an external force is applied to the support column 8, it can move relative to the first movable bracket 3 until it abuts against the support wheel 9. During this process, the support column 8 forces the second movable bracket 5 to rotate around its rotation point, thus continuously and stably pressing the second guide wheel 7 against the surface of the power tube. Conversely, moving the support column 8 in the opposite direction gradually moves it away from the support wheel 9, thereby gradually releasing the support wheel 9. Without the constraint of the support column 8, the second movable bracket 5 can rotate in the opposite direction to gradually release the power tube. Finally, sliding the first movable bracket 3 in the opposite direction completely releases the power tube. Of course, even after the support column 8 is released, when the first movable bracket 3 and the second movable bracket 5 move to the upper surface of the power pipe, the second movable bracket 5 will also be affected by its own weight, causing the second guide wheel 7 to adhere to the upper surface of the power pipe until it moves to the lower surface of the power pipe. Therefore, when positioning the second guide wheel 7, the first movable bracket 3 and the second movable bracket 5 need to be placed on the lower surface of the power pipe before moving the support column 8.

[0031] In this embodiment, the size of the cavity 6 and the position of the cutter 4 are adjusted by a first movable bracket 3 that can slide relative to the fixed bracket 1. This not only facilitates the assembly and disassembly of the cutting device but also improves its versatility to accommodate power pipes of different diameters. Furthermore, the movement of the support column 8 can abut against or release the support wheel 9 located at the second movable bracket 5. This allows the second movable bracket 5 to rotate in both directions by engaging or disengaging the support column 8 and the support wheel 9. This enables the second guide wheel 7 located at the second movable bracket 5 to provide clamping force to the power pipe or to release the power pipe. Simultaneously, the rotation of the fixed bracket 1 and the first movable bracket 3 in the same direction ensures that the cutter 4 moves stably in the trajectory formed by the guide wheels, providing a stable clamping force and avoiding cut surface deviation or unevenness caused by poor contact.

[0032] like Figure 3 , Figure 4As shown, in one embodiment, the first movable bracket 3 is provided with a threaded hole 301, and the support column 8 is threadedly connected to the threaded hole 301. Specifically, in order to allow the support column 8 to move relative to the first movable bracket 3, this embodiment provides a threaded hole 301 at the first movable bracket 3, and the support column 8 is threadedly connected to the first movable bracket 3 through the threaded hole 301; thus, rotating the support column 8 forward or backward will cause the support column 8 to gradually press against or gradually release the support wheel 9, so that the second movable bracket 5 can be rotated by the support wheel 9, causing the second guide wheel 7 to contact or separate from the surface of the power pipe. At the same time, the threaded support column 8 can also adjust the clamping force of the second guide wheel 7. Of course, in order to adapt to the shape of the first movable bracket 3 and the second movable bracket 5, and the position of the support wheel 9, such as Figure 3 As shown, multiple threaded holes 301 can be provided in the first movable bracket 3, and one of the support columns 8 can be installed.

[0033] like Figures 1-4 As shown, in one embodiment, the first movable bracket 3 is provided with a clamp 302. The clamp 302 has a space for the fixed bracket 1 to pass through and is used to clamp the outer periphery of the fixed bracket 1. Specifically, after the first movable bracket 3 slides to a suitable position, it needs to be fixed to the fixed bracket 1 to accommodate power pipes of different diameters. For this purpose, this embodiment provides a clamp 302 at the end of the first movable bracket 3. The clamp 302 forms a space for the slide rail of the fixed bracket 1 to pass through. Under normal conditions, the first movable bracket 3 can be slidably connected to the fixed bracket 1 through the clamp 302, that is, the slide rail of the fixed bracket 1 slides through the aforementioned space. When the clamp 302 is locked, the clamp 302 can be used to clamp the outer periphery of the fixed bracket 1 to fix the first movable bracket 3 at any height of the fixed bracket 1.

[0034] In other embodiments, the first movable bracket 3 has two clamping plates, and fasteners pass through the two clamping plates and the fixed bracket 1, fixing the first movable bracket 3 to the fixed bracket 1. That is, the above-mentioned clamping member 302 can also be replaced with two clamping plates, which are arranged opposite each other at the same end of the first movable bracket 3, and a groove is formed between the two clamping plates. This groove is slidably disposed at the slide of the fixed bracket 1 so that the first movable bracket 3 can slide relative to the fixed bracket 1. In addition, in order to fix the first movable bracket 3 at any height of the fixed bracket 1, both clamping plates are provided with first positioning holes, and multiple second positioning holes are provided at the slide of the fixed bracket 1. The multiple second positioning holes are arranged at intervals along the sliding direction. In this way, when the two clamping plates slide to a suitable height, fasteners (such as fastening bolts and fastening nuts) pass through the first positioning holes and the second positioning holes to fix the first movable bracket 3 to the fixed bracket 1.

[0035] like Figure 1-3 As shown, in one embodiment, the cutter 4 is movably disposed on the first movable bracket 3 to extend into or out of the cavity 6. Specifically, to facilitate cutting the power pipe, this embodiment provides a movable cutter 4 at the first movable bracket 3, which moves towards the cavity 6 to facilitate extending into and cutting the power pipe.

[0036] Furthermore, such as Figure 4 As shown, the first movable bracket 3 is slidably equipped with a sliding seat 10, which is connected to the cutter 4 and threadedly connected to the screw 11, so as to drive the cutter 4 to move when subjected to force. Specifically, the first movable bracket 3 is provided with an inner cavity, and the sliding seat 10 is slidably disposed in the inner cavity and connected to the cutter 4; one end of the screw 11 extends into the inner cavity and is threadedly connected to the sliding seat 10, and the other end extends out of the inner cavity. In this way, external force can rotate the screw 11, which can cause the sliding seat 10 to drive the cutter 4 to move together, so as to adjust the cutting depth of the cutter 4 by rotating the screw 11. Of course, in order to improve the stability of the sliding seat 10, a corresponding guide structure can be provided in the inner cavity, such as: a guide rod is provided along the sliding direction of the sliding seat 10, and the guide rod passes through the sliding seat 10 with a gap. Alternatively, the guide structure is a groove, and the sliding seat 10 can be slidably embedded in the groove.

[0037] like Figure 3 , Figure 4 As shown, in one embodiment, the second movable support 5 is provided with an opening 501 for avoiding the cutter 4. Specifically, in order to prevent the second movable support 5 from affecting the feed of the cutter 4, this embodiment provides an opening 501 at the second movable support 5, so that the cutter 4 can freely pass through the opening 501 to avoid the cutter 4.

[0038] like Figure 1 , Figure 2 As shown, in one embodiment, the fixed bracket 1 and / or the second movable bracket 5 are provided with a notch 101, which is V-shaped and faces the cavity 6. Specifically, since the cross-section of the power pipe is circular, in order to adapt to this circular structure and clamp the power pipe in the cavity 6, both the fixed bracket 1 and the second movable bracket 5 in this embodiment are provided with a notch 101, which is V-shaped and arranged opposite to each other, communicating with the cavity 6 to securely clamp the power pipe. In addition, in order to adapt the first movable bracket 3 and the second movable bracket 5, the notch 101 provided at the second movable bracket 5 can be the same as or different from the notch 101 at the fixed bracket 1. Figure 1 , Figure 2As shown, in this embodiment, the first guide wheel 2 and the second guide wheel 7 are both set into two groups, with each group consisting of two pairs; the two groups of first guide wheels 2 (or the two groups of second guide wheels 7) are symmetrically arranged on opposite sides of the notch 101 to improve the stability of the device.

[0039] like Figures 1-4 As shown, in one embodiment, both the fixed bracket 1 and the first movable bracket 3 are provided with handles 12, and the two handles 12 are arranged opposite to each other. Specifically, in order to facilitate the circumferential rotation of the cutting device around the power pipe under the action of external force, this embodiment provides handles 12 on both the fixed bracket 1 and the first movable bracket 3, and the cutting device can be rotated relative to the power pipe by alternately rotating the two handles 12.

[0040] The rotation angle of the second movable support 5 is 0° to ±30°. Within this range, on the one hand, it can prevent the second movable support 5 from detaching from the first movable support 3 due to excessive rotation angle; on the other hand, it can also allow the support column 8 and the support wheel 9 to cooperate and finely adjust the angle of the second movable support 5, thereby improving the operability of the device.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
