Description

Technical Field

[0001] This invention relates to the field of polishing technology, specifically to a polishing device for cable protection pipes. Background Technology

[0002] Cable protection pipes are essential accessories in power systems used to protect cables from external environmental and mechanical damage. They are widely used in urban power grids, industrial plants, rail transit, and building power distribution. Their main function is to prevent cables from being damaged by compression, corrosion, high temperatures, or insect and rodent damage during laying and operation, thereby ensuring the safe and stable operation of transmission lines. Common cable protection pipe materials include PVC (polyvinyl chloride), PE (polyethylene), MPP (modified polypropylene), CPVC (chlorinated polyvinyl chloride), and plastic-coated steel pipes.

[0003] In the manufacturing process of cable protection pipes, regardless of whether the material is plastic or metal, surface grinding is a crucial step to ensure the quality of subsequent processing and the protective performance of the pipe. If grinding is insufficient and the outer surface of the pipe cannot be cleaned properly, the remaining burrs or rough areas may become stress concentration points, inducing local cracks during subsequent transportation, bending, or pressure, thus reducing the mechanical strength of the pipe.

[0013] This invention provides a device for grinding cable protection pipes. It has the following advantages: I. This cable protection pipe grinding device, by setting up a base plate, provides a stable foundation support platform for the entire grinding device, ensuring stable and reliable operation. The first support frame serves as the mounting base for the grinding mechanism, providing rotational support for the rotating ring. The grinding mechanism, the device's "grinding execution unit," performs circumferential grinding on the outer surface of the cable protection pipe, removing burrs and unevenness.

[0014] Second, this cable protection pipe grinding device, by incorporating a chip removal mechanism, serves as the device's "chip collection unit." During the grinding process, it simultaneously absorbs and collects the generated metal chips and dust, maintaining a clean working environment. A second support frame is used to fix the chip removal mechanism to the upper surface of the base plate, ensuring it remains coaxial with the grinding mechanism.

[0015] III. This cable protection pipe grinding device, through the setting of fixed columns and a bottom cover, forms the bottom support and positioning seat for the cable protection pipe. The arc-shaped surface of the bottom cover fits against the outer wall of the pipe. A height-adjustable upper clamping mechanism is formed by setting limiting columns, a sliding tube, and a top cover. The top cover is located directly above the bottom cover, and its height is adjusted by sliding the sliding tube along the limiting columns to accommodate pipes of different diameters. A first spring provides continuous upward elastic force, ensuring the top cover always presses firmly against the cable protection pipe, preventing the pipe from shaking during grinding, while also allowing for quick clamping and removal of the pipe.

[0016] IV. This cable protection pipe grinding device, by setting a track groove and a sliding block, constitutes a linear motion guide mechanism for the sliding block. A rotating column connects the sliding block to a limiting sleeve, causing the limiting sleeve to push the sliding block along the track groove. A first anti-slip column, serving as a support and tensioning wheel for the sanding belt, can be designed with a rough or raised outer surface to increase friction with the sanding belt and prevent slippage.

[0017] V. This cable protection pipe grinding device, by setting a second anti-slip post, is fixed to the outer surface of the rotating disk, forming a triangular distribution with the two first anti-slip posts. This three-point support structure ensures the abrasive belt forms a stable triangular circumferential path, with a section of the abrasive belt protruding from the edge of the rotating disk for contact and grinding of the cable protection pipe surface. By adjusting the position of the first anti-slip posts, the tension of the abrasive belt can be changed, ensuring grinding pressure and contact stability. The abrasive belt, being a grinding element that directly contacts the pipe surface, performs circumferential grinding of the pipe's outer wall as the rotating disk rotates.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-10 As shown, the present invention provides a technical solution: a cable protection pipe grinding device, including a base plate 1, and a first support frame 2 fixed on the upper surface of the base plate 1; A fixing post 7 is fixedly mounted on the upper surface of the base plate 1. A bottom cover 8 is fixedly mounted on the top of the fixing post 7. A limiting post 9 is fixedly mounted on the outer side of the bottom cover 8. A sliding tube 10 is slidably connected to the outer surface of the limiting post 9. A top cover 11 is fixedly mounted on the outer surface of the sliding tube 10. The top cover 11 is located directly above the bottom cover 8. A first spring 12 is sleeved on the outer surface of the limiting post 9. The top of the first spring 12 is fixed to the bottom end of the sliding tube 10. By setting the fixing post 7 and the bottom cover 8, the bottom support and positioning seat of the cable protection pipe are formed. The arc-shaped surface of the bottom cover 8 fits against the outer wall of the pipe. By setting the limiting post 9, the sliding tube 10 and the top cover 11, a liftable upper pressing mechanism is formed. The top cover 11 is located directly above the bottom cover 8. The height is adjusted by sliding the sliding tube 10 along the limiting post 9 to accommodate pipes of different diameters. By setting the first spring 12, a continuous upward elastic force is provided, so that the top cover 11 always presses the cable protection tube tightly, preventing the tube from shaking during the grinding process, while allowing the tube to be quickly clamped and removed.

[0022] A grinding mechanism 3 is fixedly installed inside the first support frame 2. A base plate 1 provides a stable foundation support platform for the entire grinding device, ensuring stable and reliable operation. The first support frame 2 serves as the mounting base for the grinding mechanism 3, providing rotational support for the rotating ring 35. The grinding mechanism 3 is the "grinding execution unit" of the device, performing circumferential grinding on the outer surface of the cable protection pipe to remove burrs and unevenness. The grinding mechanism 3 includes a rotating ring 35, with a first rolling bearing 34 fixed to its outer surface. The outer ring of the first rolling bearing 34 is fixed to the inner wall of the first support frame 2, and a rotating disk 37 is fixed to the inner wall of the rotating ring 35. The rotating ring 35 can rotate around the first rolling bearing 34, serving as the rotational power transmission component for the grinding mechanism 3 and the chip removal mechanism 6. The rotating disk 37 rotates with the rotating ring 35, and an abrasive belt 318 is mounted on its surface to grind the cable protection pipe. The grinding mechanism 3 also includes a mounting bracket 31, which is fixed to the upper surface of the base plate 1. A stepper motor 32 is fixed to the inner wall of the mounting bracket 31. A gear 33 is mounted on the output end of the stepper motor 32 via a coupling. A gear ring 36 is fixed to the outer surface of the rotating ring 35, and the gear ring 36 meshes with the gear 33. The mounting bracket 31 provides a stable mounting platform for the stepper motor 32. The stepper motor 32 is the rotational power source of the grinding mechanism 3, and its rotational speed is precisely controllable, allowing adjustment of the rotational speed according to the grinding process requirements. The gear 33 and gear ring 36 form a transmission system that transmits the torque of the stepper motor 32 to the rotating ring 35, driving the entire grinding mechanism 3 and the chip removal mechanism 6 to rotate synchronously.

[0023] A threaded ring 38 is fixed to the outer surface of the rotating disk 37. A threaded post 39 is threadedly connected to the inner cavity of the threaded ring 38. A limit ring 310 is rotatably connected to the outer surface of the threaded post 39. A support rod 311 is fixed to the outer surface of the limit ring 310. Limit sleeves 312 are fixed to both ends of the support rod 311. By setting the threaded ring 38 and the threaded post 39, a manual adjustment mechanism is formed. Rotating the threaded post 39 can change its extension length within the threaded ring 38, thereby adjusting the position of the support rod 311 and the sliding block 315. By setting the limit ring 310, the rotational movement of the threaded post 39 is decoupled from the linear movement of the support rod 311, preventing the support rod 311 from rotating with the threaded post 39. By setting the support rod 311 and the limit sleeves 312, the sliding block 315 is connected and driven to slide along the track groove 313, thereby realizing the adjustment of the tension of the sanding belt 318.

[0024] The outer surface of the rotating disk 37 has a track groove 313. A sliding block 315 is slidably connected to the track groove 313 on the outer surface of the rotating disk 37. A rotating column 314 is fixed to one end of the sliding block 315 and is rotatably connected to the inner cavity of the limiting sleeve 312. A first anti-slip column 316 is fixed to the other end of the sliding block 315. The track groove 313 and the sliding block 315 form a linear motion guide mechanism for the sliding block 315. The rotating column 314 rotatably connects the sliding block 315 to the limiting sleeve 312, causing the limiting sleeve 312 to push the sliding block 315 to slide along the track groove 313. The first anti-slip column 316 serves as a support and tensioning wheel for the sanding belt 318. Its outer surface can be designed to be rough or have protrusions to increase the friction with the sanding belt 318 and prevent the sanding belt 318 from slipping.

[0025] A second anti-slip post 317 is fixed to the outer surface of the rotating disk 37. Two first anti-slip posts 316 and the second anti-slip post 317 are triangularly distributed. An abrasive belt 318 is fitted onto the outer surfaces of the first anti-slip posts 316 and the second anti-slip post 317. By setting the second anti-slip post 317, it is fixed to the outer surface of the rotating disk 37 and triangularly distributed with the two first anti-slip posts 316. The three-point support structure enables the abrasive belt 318 to form a stable triangular loop path, with a section of the abrasive belt 318 exposed at the edge of the rotating disk 37 for contact and grinding with the surface of the cable protection pipe. By adjusting the position of the first anti-slip post 316, the tension of the abrasive belt 318 can be changed to ensure grinding pressure and contact stability. The abrasive belt 318 is a grinding element that directly contacts the surface of the pipe, and it performs circumferential grinding on the outer wall of the pipe as the rotating disk 37 rotates.

[0026] The chip removal mechanism 6 is used to remove debris generated during the grinding of the outer surface of the cable protection steel pipe. A second support frame 5 is fixed to the lower surface of the chip removal mechanism 6, and the bottom end of the second support frame 5 is fixed to the upper surface of the base plate 1. By setting up the chip removal mechanism 6, it acts as a "debris collection unit" of the device, simultaneously absorbing and collecting the metal debris and dust generated during the grinding process, keeping the working environment clean. By setting up the second support frame 5, the chip removal mechanism 6 is fixed to the upper surface of the base plate 1, making it coaxial with the grinding mechanism 3. The chip removal mechanism 6 includes a rotating box 61, and a connecting frame 4 is fixed to the outer surface of the rotating box 61. The end of the connecting frame 4 away from the rotating box 61 is fixed to the outer surface of the rotating ring 35. By setting up the connecting frame 4, the rotating box 61 and the rotating ring 35 are fixedly connected, so that the chip removal mechanism 6 rotates synchronously with the grinding mechanism 3, ensuring that the debris collection port is always aligned with the grinding area. A second rolling bearing 62 is fixed to the outer surface of the rotating box 61. A fixing ring 63 is fixed to the outer ring of the second rolling bearing 62. The fixing ring 63 is fixed to the top of the second support frame 5. An exhaust port 64 penetrates the lower surface of the fixing ring 63. A discharge pipe 65 is fixed to the bottom end of the exhaust port 64. Several evenly distributed spiral blades 66 are fixed to the inner wall of the rotating box 61. By setting the second rolling bearing 62, the rotating box 61 is supported to rotate smoothly within the fixing ring 63, so that the rotating box 61 can rotate synchronously with the grinding mechanism 3. By setting the fixing ring 63, the chip removal mechanism 6 is fixed to the top of the second support frame 5. By setting the exhaust port 64 and the discharge pipe 65, the sucked-in debris and dust are discharged to the collection container. By setting the spiral blades 66, fixed to the inner wall of the rotating box 61, an axial airflow is generated when the rotating box 61 rotates, which sucks the grinding debris into the inner cavity of the rotating box 61 and pushes it to the exhaust port 64 for discharge.

[0027] The outer surface of the rotating chamber 61 has several evenly distributed vent holes 67. A cover 68 is fitted over the outer surface of the rotating chamber 61, and the cover 68 is connected to the inner cavity of the rotating chamber 61 through the vent holes 67. A limiting groove is formed on the outer surface of the cover 68, and a sliding plate 69 is slidably connected to the limiting groove. A connecting pipe 611 passes through the outer surface of the sliding plate 69, and the end of the connecting pipe 611 extends into the inner cavity of the cover 68. By providing vent holes 67, the inner cavity of the rotating chamber 61 and the inner cavity of the cover 68 are connected to form an airflow channel. The cover 68 serves as a transition cavity for debris intake, covering the outside of the vent holes 67. By providing the sliding plate 69 and the limiting groove, the connecting pipe 611 can slide up and down along the cover 68 to adapt to the grinding position of pipes of different diameters. By setting a connecting pipe 611, the end of which extends into the inner cavity of the cover 68, close to the polishing area, the debris is sucked into the cover 68 and the rotating box 61.

[0028] A second spring 610 is fixed to the lower surface of the connecting pipe 611, and the bottom end of the second spring 610 is fixed to the outer surface of the cover 68. A third rolling bearing 612 is fixed to the inner wall of the end of the connecting pipe 611 away from the sliding plate 69. A conical shell 613 is fixed to the inner ring of the third rolling bearing 612. A roller 614 is fixed to the outer surface of the conical shell 613. Several evenly distributed feed inlets 616 are opened on the outer surface of the roller 614, and several evenly distributed rubber strips 615 are fixed to the outer surface of the roller 614. By setting the second spring 610, a downward elastic force is provided to the connecting pipe 611, so that the roller 614 at its end always keeps in contact with the surface of the cable protection pipe, ensuring that debris is effectively sucked in. By setting the third rolling bearing 612, the conical shell 613 and the roller 614 are supported to rotate freely at the end of the connecting pipe 611. By setting the conical shell 613, airflow and debris are guided into the connecting pipe 611. By setting up roller 614, the rubber strips 615 on its outer surface roll into contact with the pipe surface during the grinding process, playing an auxiliary cleaning and guiding role. By setting up feed inlet 616, which is evenly distributed on the surface of roller 614, it serves as the inlet for debris to enter the connecting pipe 611. When roller 614 rotates with the pipe or rotating box 61, debris is sucked in from feed inlet 616, enters the connecting pipe 611 through conical shell 613, then enters the rotating box 61 through cover 68 and vent 67, and is finally pushed to discharge pipe 65 by spiral blades 66.

[0029] Working principle: The cable protection tube to be ground is placed on the arc-shaped surface of the bottom cover 8. Under the elastic force of the first spring 12, the sliding tube 10 slides upward along the limiting post 9, driving the top cover 11 to rise and press against the upper surface of the tube. The bottom cover 8 and the top cover 11 together form a reliable positioning of the tube, preventing the tube from shaking during the grinding process. One end of the tube passes through the central area of ​​the rotating disk 37 of the grinding mechanism 3, so that the outer wall of the tube contacts the abrasive belt 318; Depending on the pipe diameter, the threaded post 39 is rotated to adjust its extension length within the threaded ring 38. This, along with the support rod 311, pushes the sliding block 315 to slide along the track groove 313, changing the position of the first anti-slip post 316 and thus tensioning the abrasive belt 318. The stepper motor 32 starts, driving the gear ring 36 to rotate via the gear 33, which in turn rotates the rotating ring 35, the rotating disk 37, and the entire grinding mechanism 3. The abrasive belt 318 rotates at high speed with the rotating disk 37, generating relative friction with the outer wall of the pipe for circumferential grinding. The triangularly distributed first and second anti-slip posts 316 and 317 ensure the tension and stability of the abrasive belt 318. When the grinding mechanism 3 rotates, it drives the rotating box 61 to rotate synchronously via the connecting frame 4. The spiral blades 66 on the inner wall of the rotating box 61 generate axial airflow as it rotates, creating negative pressure within the rotating box 61. Simultaneously, the roller 614 at the end of the connecting pipe 611, under the action of the second spring 610, constantly presses against the surface of the pipe. Metal chips and dust generated during grinding are sucked in through the feed port 616 on the surface of the roller 614, and enter the inner cavity of the rotating box 61 via the conical shell 613, connecting pipe 611, cover 68, and vent 67. The spiral blades 66 push the sucked-in chips to the exhaust port 64, and discharge them through the discharge pipe 65 to the collection container. The rubber strip 615 assists in cleaning the surface of the pipe as the roller 614 rotates. Stepper motor 32 continuously drives rotating disk 37 to rotate, and sanding belt 318 performs continuous and uniform circumferential grinding on the outer wall of the pipe. The operator can move the pipe axially so that the sanding belt 318 covers the entire length of the pipe, achieving full-length grinding. During the grinding process, top cover 11 and bottom cover 8 maintain stable clamping of the pipe to prevent axial movement.
