They are an ideal replacement for traditional power cable sheathing pipes. In order to connect and fix power pipes, holes need to be drilled on their surface.

[0003] However, there are many specifications and models of existing power pipes. Traditional power pipe opening devices are generally of fixed specifications and can only handle power pipes of a single specification. When other specifications of power pipes need to be handled, workers need to change the clamps. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-5 A CPVC power pipe hole-opening and positioning device is disclosed. A base plate 1 serves as the foundation of the device, with an adjustment component 2 mounted on top. A mounting frame 3 is mounted on the adjustment component 2, and a clamping component 4 is mounted on the mounting frame 3. The adjustment component 2 drives a slider 27 to slide via a bidirectional lead screw 28, adjusting the distance between the two mounting frames 3 to accommodate CPVC power pipes of different lengths. The clamping component 4 drives a linkage structure via a threaded handle 22, causing the clamping claw 8 to extend and retract, accommodating power pipes of different diameters without requiring clamp replacement. A motor 31 drives a rotating shaft 5 to rotate via a bevel gear, allowing the power pipe to rotate synchronously for easy adjustment of the hole opening position. Through the coordination of spacing adjustment, diameter adaptation, and rotational positioning, the device solves the problems of fixed specifications and frequent clamp replacement required in traditional devices, achieving precise positioning and hole opening for CPVC power pipes of various specifications, improving operational convenience and processing efficiency.

[0018] First, refer to Figure 1In this embodiment, the base plate 1 is a horizontal plate structure with high overall rigidity and is not easily deformed after long-term use, providing a stable installation reference for the adjustment component 2 and the mounting bracket 3. A sliding groove 26 is opened on the top of the base plate 1, which extends along the length direction. A bidirectional lead screw 28 is rotatably installed inside the groove 26. The number of sliders 27 is the same as that of the mounting brackets 3. The top of the sliders 27 is fixedly connected to the bottom of the mounting brackets 3. When the bidirectional lead screw 28 rotates, it drives the sliders 27 on both sides to move in opposite directions along the groove 26, thereby driving the mounting brackets 3 to move synchronously and adjust the distance between the two mounting brackets 3. When the power pipe is long, the mounting brackets 3 move to the sides to increase the distance. When the length is short, the mounting brackets 3 move to the middle to decrease the distance. Different lengths of CPVC power pipes can be adapted without replacing the mounting brackets 3 or clamps. The operation is simple and efficient.

[0019] One end of the bidirectional lead screw 28 extends to the outside of the base plate 1, making it convenient for operators to rotate and adjust. The threaded drive ensures that the slider 27 moves smoothly and the spacing is adjusted accurately, avoiding the positioning deviation of the power pipe caused by the offset of the mounting bracket 3. The bottom of the base plate 1 remains flat and is stable and does not wobble when placed on the ground or workbench, providing a stable foundation for subsequent clamping and drilling.

[0020] Then, refer to Figure 2 In this embodiment, the mounting bracket 3 is fixed on the top of the slider 27 and has a frame structure, providing installation support for all components of the clamping assembly 4, ensuring accurate positioning and smooth linkage of each component. The mounting bracket 3 has a placement hole 7 on its side for the CPVC power pipe to pass through, and also provides installation space for the clamping claw 8. The top has a long groove 15 and a vertical groove 24, which provide sliding tracks for the moving column 14 and the horizontal bar 23, respectively, to ensure that the linkage structure moves without jamming. The top is fixed with a support 20 and a motor 31, and the side is rotatably equipped with a second bevel gear 30, forming an integrated design of power transmission and structural support.

[0021] The structural design of the mounting bracket 3 is adapted to the linkage logic of the clamping component 4. It will not hinder the extension and retraction of the clamping claw 8 and the rotation of the power tube, and can provide reliable support for each component, avoid positioning deviation caused by vibration, and ensure the accuracy of the hole opening.

[0022] Secondly, see Figure 4In this embodiment, the clamping assembly 4 is mounted on the mounting bracket 3 and is the key to adapting to power pipes of different diameters. Through the design of threaded drive, multi-rod linkage, and elastic clamping, it ensures that the clamping is firm and does not damage the pipe wall. It includes a rotating shaft 5, a flexible cylinder 6, clamping claws 8, a sleeve rod 10, a rotating ring 12, a moving ring 13, a moving plate 21, a threaded handle 22, and a spring 25. The rotating shaft 5 is rotatably mounted on the mounting bracket 3, with the flexible cylinder 6 fixed at one end. Multiple clamping claws 8 are installed in the placement hole 7 on the side of the mounting bracket 3. One end of the clamping claw 8 is in contact with the inner wall of the flexible cylinder 6. The clamping claws 8 are evenly distributed around the placement hole 7, which can wrap the CPVC power pipe from multiple directions, ensuring uniform clamping force and avoiding excessive local pressure that could cause pipe wall deformation. The flexible cylinder 6 has a certain degree of elasticity, which can buffer the clamping force of the clamping claws 8, further protecting the pipe wall and preventing damage.

[0023] A base 9 is slidably mounted on the side of the clamping claw 8. A sleeve rod 10 is slidably mounted on the base 9. One end of the sleeve rod 10 is slidably engaged with the sliding groove 11 of the flexible cylinder 6, and the other end is fixed with a rotating ring 12. Moving rings 13 are rotatably connected to both sides of the rotating ring 12. A moving column 14 is fixed to the top of the moving ring 13. The moving column 14 passes through the long groove 15 of the mounting frame 3 and is fixed to the top of the first connecting seat 16. A first rotating rod 17 is rotatably connected to the first connecting seat 16. The other end of the first rotating rod 17 is rotatably connected to a rotating shaft 18. A second rotating rod 19 is also rotatably connected to the rotating shaft 18. The other end of the second rotating rod 19 is rotatably connected to a support 20 at the top of the mounting frame 3. A moving plate 21 is rotatably connected to the rotating shaft 18. A threaded handle 22 is rotatably mounted on the mounting frame 3. The threaded handle 22 is threadedly engaged with the moving plate 21. A crossbar 23 is fixed to the side of the moving plate 21. The crossbar 23 is slidably engaged with the vertical groove 24 of the mounting frame 3.

[0024] When the threaded handle 22 is rotated, the thread drives the moving plate 21 to move horizontally. The moving plate 21 drives the rotating shaft 18 to move synchronously. The rotating shaft 18 pulls the first rotating rod 17 and the second rotating rod 19 to rotate. The first rotating rod 17 drives the moving column 14 to slide along the long groove 15 through the first connecting seat 16. The moving column 14 drives the moving ring 13 and the rotating ring 12 to move synchronously. The rotating ring 12 drives the clamping claw 8 to slide along the base 9 through the sleeve rod 10, realizing the extension and retraction of the clamping claw 8. When the handle is rotated to bring the moving plate 21 closer to the support 20, the clamping claw 8 retracts inward to clamp the CPVC power pipe. When the handle is rotated in the opposite direction, the clamping claw 8 extends outward to release the power pipe, adapting to the needs of different diameters.

[0025] A spring 25 is fixed on the base 9. The spring 25 is sleeved on the sleeve rod 10, and the other end is fixed to the rotating ring 12. The spring 25 is always in a slightly stretched state, which can provide a continuous preload force for the clamping claw 8 to ensure a firm clamping. At the same time, when the power tube is released, the spring 25 pulls the rotating ring 12 to reset, causing the clamping claw 8 to extend automatically, simplifying the operation. The elastic buffer of the spring 25 can also absorb the small vibrations during clamping, preventing the power tube from shifting due to vibration and improving the positioning accuracy.

[0026] Finally, see Figure 3 In this embodiment, the power assembly provides power for adjusting the opening position of the power tube. The power tube is rotated by the motor 31, eliminating the need for manual rotation and improving operational convenience. The assembly includes the motor 31, the second bevel gear 30, and the first bevel gear 29. The motor 31 is fixed to the top of the mounting bracket 3. The output shaft is connected to the second bevel gear 30 by a key. The first bevel gear 29 is fixed to the side of the rotating shaft 5. The first bevel gear 29 meshes with the second bevel gear 30. When the motor 31 is started, it drives the second bevel gear 30 to rotate. The second bevel gear 30 drives the first bevel gear 29 to rotate, thereby driving the rotating shaft 5 and the flexible cylinder 6 to rotate synchronously. The flexible cylinder 6 drives the CPVC power tube held by the clamping claw 8 to rotate through friction, thereby achieving circumferential adjustment of the opening position.

[0027] The speed of motor 31 is adjustable, which can precisely control the rotation angle of the power tube, making it convenient for operators to adjust the power tube to the preset opening position without manually prying or rotating the power tube. This saves physical effort and prevents the power tube from shifting during the adjustment process, ensuring the accuracy of the opening position.

[0028] Working principle: When using this CPVC power pipe hole-opening positioning device, first check the operating status of each component to ensure that the bidirectional lead screw 28 of the adjusting component 2 rotates smoothly, the slider 27 slides without jamming, the clamping claw 8 of the clamping component 4 extends and retracts flexibly, the spring 25 has normal elasticity, the threaded handle 22 rotates without jamming, the motor 31 runs smoothly, the bevel gear meshes without abnormal noise, the soft cylinder 6 is undamaged and can properly buffer the clamping force.

[0029] Based on the length of the CPVC power pipe to be drilled, rotate the double-acting screw 28 on the outer side of the base plate 1 to drive the two mounting brackets 3 to move along the slide groove 26. Adjust the spacing of the mounting brackets 3 so that the spacing is slightly less than the length of the power pipe, ensuring that both ends of the power pipe can be clamped by the clamping components 4 of the two mounting brackets 3 at the same time, avoiding one end being suspended and causing positioning deviation.

[0030] Rotate the threaded handle 22 on the mounting bracket 3 to drive the moving plate 21 to move, causing the clamping claw 8 to extend outward, increasing the internal space of the clamping assembly 4, and reserving a gap for inserting the power pipe.

[0031] Pass the CPVC power pipe to be drilled through the placement holes 7 of the two mounting brackets 3, ensuring that the power pipe is in a horizontal state, with both ends located at the center of the clamping components 4 of the two mounting brackets 3 respectively, and the drilling area located between the two mounting brackets 3 without obstruction.

[0032] The threaded handles 22 on the two mounting brackets 3 are rotated synchronously to drive the clamping claws 8 to retract inward until the clamping claws 8 fit against the outer wall of the power pipe. The soft cylinder 6 is slightly deformed under the clamping force and tightly wraps the power pipe. During the clamping process, observe whether the power pipe is horizontal. If it is tilted, finely adjust the threaded handles 22 to ensure that the power pipe does not deviate. The pre-tightening force of the spring 25 keeps the clamping firm and avoids damaging the pipe wall.

[0033] Gently push the power pipe to confirm that it is not loose or displaced. Observe whether the clamping claw 8 is evenly attached to the pipe wall and there is no local suspension. Check the surface of the power pipe to ensure that there are no indentations or damage. After the clamping is qualified, proceed to the next step.

[0034] Start the motor 31 on the top of the mounting bracket 3. The motor 31 drives the rotating shaft 5 to rotate synchronously with the power tube through the bevel gear. Adjust the speed of the motor 31 according to the opening requirements to control the rotation speed of the power tube and avoid inaccurate positioning due to excessive speed.

[0035] The operator observes the markings on the surface of the power tube or uses an external measuring tool. When the power tube rotates to the preset opening position, the motor 31 is turned off and the power tube stops rotating. If there is a deviation in position, the motor 31 can be started to make fine adjustments until the opening position is completely aligned with the opening tool, and the positioning is completed.

[0036] Align the hole-making tool with the pre-positioned location and start the hole-making operation. During the hole-making process, the clamping component 4 keeps the power tube fixed to prevent the power tube from shifting due to the impact force of the hole-making, and ensures that the hole size is accurate and the edges are flat.

[0037] After the hole is drilled, rotate the threaded handle 22 in the opposite direction to drive the clamping claw 8 to extend outward and release the CPVC power pipe. If the clamping claw 8 is not fully reset, the spring 25 will pull the rotating ring 12 to automatically reset and assist in releasing the pipe. The processed power pipe can then be taken out of the placement hole 7 and placed in the dedicated storage area.

[0038] Rotate the bidirectional lead screw 28 to adjust the two mounting brackets 3 to the initial spacing, turn off the power to the motor 31, clean the debris and dust on the surface of the device, check whether the clamping claws 8 and the soft cylinder 6 are damaged, and whether the spring 25 is in normal elasticity, to ensure that the equipment is in good condition and ready for the next use.

[0039] When changing power pipes of different lengths, no parts need to be disassembled. Simply rotate the bidirectional screw 28 to adjust the spacing of the mounting bracket 3 to quickly adapt. The whole process only takes tens of seconds, greatly saving the adjustment time.

[0040] When changing power pipes of different diameters, turn the threaded handle 22 to drive the clamping jaws 8 to extend and retract. There is no need to change the clamping jaws 8 or the clamps. It can adapt to various diameter specifications. The operation is convenient and requires no professional skills.
