[0037] 1. This grinding device for producing power cable protection pipes features a fixed clamp that moves the protection pipe from front to back, allowing the grinding machine to thoroughly grind the pipe surface without moving the machine, thus preventing shaking and improving grinding stability and precision. The inner ring rotates within the fixed clamp, adjusting the contact surface between the protection pipe and the welding machine for thorough grinding without blind spots, enhancing grinding convenience. The U-shaped fixing component clamps the pipe wall, making the protection pipe fit more snugly against the fixed clamp and increasing friction, facilitating the rotation of the protection pipe with the fixed clamp and further improving grinding convenience. The U-shaped fixing component slides away from the protection pipe, facilitating disassembly and improving the ease of operation of the device.

[0038] 2. This grinding device for producing power cable protection pipes inserts the rear end of the protection pipe between the movable half-hoops, preventing the protection pipe from shifting or tilting during grinding, thus affecting the grinding accuracy. When the protection pipe needs to be disassembled, simply push the two movable half-hoops to the sides to open them, thereby ensuring that the protection pipe remains stable while making it easy to remove after grinding. The elastic restoring action of the second elastic telescopic rod causes the movable half-hoops to automatically reset and fit, thereby clamping the rear end of the protection pipe, improving the ease of use of the device.

[0039] 3. The grinding device for producing power cable protection pipes opens the side and lower clamps, inserts the protection pipe, and then moves the side and lower clamps. The elastic reset action of the torsion spring drives the side and lower clamps to reset and clamp the rear wall of the protection pipe, further improving the stability of the protection pipe during grinding.

[0040] 4. The grinding device used in the production of power cable protection pipes allows debris to fall or follow the surface of the protection pipe into the receiving groove, thus preventing debris from splashing outside the device and being difficult to remove. Furthermore, debris that splashes to the side of the protection pipe is blocked by the baffle and then falls onto the connecting plate and the guide plate, and then slides down the inclined surface of the guide plate into the receiving groove, further preventing debris from flying out and affecting the working environment.

[0041] 5. The grinding device for the production of power cable protection pipes has a push plate that contacts the inner wall of the receiving groove, scraping off the debris adhering to the inner wall of the receiving groove and pushing it backward onto the discharge channel. The debris falls downward into the collection frame for collection, which facilitates subsequent processing by the staff and improves work efficiency and ease of operation. When the debris falls into the collection frame, it is blocked by the cover plate and cannot be discharged. Opening the cover plate can quickly remove the debris from the collection frame.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1-7One embodiment of the present invention is: a grinding device for producing power cable protection pipes, comprising an operating table 1, a grinding bracket 2 fixedly connected to the upper surface of the operating table 1, a grinding machine mounted on the grinding bracket 2 for grinding the surface of the protection pipe, linear motors 3 fixedly connected to both sides of the upper surface of the operating table 1, a moving base 4 fixedly connected to the moving end of the linear motors 3, a moving bracket 5 fixedly connected to the upper surface of the moving base 4, and a fixing clamp 6 fixedly connected to the upper surface of the moving bracket 5 for fixing the front end of the protection pipe and driving the protection pipe to move, and a movable limiting device 7 disposed above the operating table 1 for limiting the rear end of the protection pipe. Support is provided to make the protective tube more stable during grinding. The chip collection device 8 is set inside the operating table 1. The operating table 1 is used to protect and collect the chips generated during grinding. The fixing hoop 6 drives the protective tube to move from front to back, so that the grinder can grind the surface of the tube completely without moving the grinder, avoiding the grinder shaking and improving the stability and accuracy of grinding. The inner ring 10 rotates inside the fixing hoop 6, thereby adjusting the contact surface between the protective tube and the welding machine, so as to grind the protective tube without dead angles and improve the convenience of grinding. The operating table 1 includes a support plate 9, which is fixedly connected to both sides of the circumference of the fixing hoop 6. The support plate 9 is used to lift the fixing hoop. 6. Support force: The inner collar 10 is rotatably connected to the inner surface of the fixing hoop 6. The inner collar 10 is used to drive the protective tube to rotate. A gear ring 12 is fixedly connected to the circumferential surface of the inner collar 10. The transmission gear 11 is rotatably connected to the side surface of the support plate 9. The transmission gear 11 is driven by a motor. The operating table 1 also includes a positioning slide rail 13. The positioning slide rail 13 is fixedly connected to the front side of the fixing hoop 6. A T-shaped slider 14 is slidably connected to the inner surface of the positioning slide rail 13. An elastic telescopic rod 15 is fixedly connected to the rear end of the inner wall of the positioning slide rail 13. A U-shaped fixing member 16 is fixedly connected to the side of the T-shaped slider 14 that extends out of the positioning slide rail 13. The U-shaped fixing member 16 is used to clamp the front end wall of the protective tube. The upper surfaces of the support plate 9 and the movable bracket 5 are fixedly connected, the lower surface of the movable bracket 5 abuts against the upper surface of the operating table 1, the linear motor 3 is fixedly connected to the front side of the grinding bracket 2, the transmission gear 11 and the gear ring 12 are meshed, the gear ring 12 is rotatably connected to the inner surface of the fixing hoop 6, the free end of the elastic telescopic rod 15 is fixedly connected to the rear side of the T-shaped slider 14, the U-shaped fixing part 16 clamps the tube wall, thereby making the protective tube fit more closely to the fixing hoop 6 to enhance friction, making it easier for the protective tube to rotate with the fixing hoop 6, further improving the convenience of grinding, the U-shaped fixing part 16 slides away from the protective tube, thereby making it easier to disassemble the protective tube, improving the convenience of device operation.

[0052] Working principle: Insert one end of the protective tube into the fixing clamp 6 from back to front. Then start the linear motor 3 and the grinding machine on the grinding bracket 2. The linear motor 3 drives the moving seat 4 to move from front to back. The moving seat 4 drives the moving bracket 5 and the fixing clamp 6 to move from front to back. The fixing clamp 6 then drives the protective tube to move from front to back. At this time, the grinding machine can grind the surface of the protective tube. By moving the protective tube, the grinding machine can grind the entire surface of the tube. At the same time, there is no need to move the grinding machine, avoiding the shaking of the grinding machine and improving the stability and accuracy of grinding. The rotating shaft drives the transmission gear 11 to rotate, the transmission gear 11 drives the gear ring 12 to rotate, and the gear ring 12 drives the inner collar 10 to rotate within the fixing clamp 6, thereby adjusting the contact surface between the protective tube and the welding machine, and thus grinding the protective tube without dead angles. The grinding process is improved, and the support plate 9 supports the fixing hoop 6 during the movement of the protective tube, making the protective tube more stable. When the protective tube is inserted into the fixing hoop 6, its front end is inserted between the U-shaped fixing parts 16, so that the U-shaped fixing parts 16 clamp the tube wall, thereby making the protective tube fit the fixing hoop 6 more closely and increasing the friction, making it easier for the protective tube to rotate with the fixing hoop 6, further improving the convenience of grinding. When it is necessary to disassemble the protective tube, pull the U-shaped fixing parts 16 forward. The U-shaped fixing parts 16 slide in the positioning slide rail 13 through the T-shaped slider 14 and move away from the protective tube, thereby facilitating the disassembly of the protective tube and improving the convenience of device operation. After releasing the U-shaped fixing parts 16, the elastic reset action of the elastic telescopic rod 15 drives the T-shaped slider 14 and the U-shaped fixing parts 16 to reset and move closer to the fixing hoop 6 again.

[0053] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the movable limiting device 7 includes a sliding seat 71, which is slidably connected to the upper surface of the operating table 1. A movable half-hoop 73 is slidably connected to the upper surface of the sliding seat 71. The movable half-hoop 73 is used to clamp and fix the rear end of the inner wall of the protective tube. A convex plate 72 is fixedly connected to both sides of the upper surface of the sliding seat 71. An elastic telescopic rod 74 is fixedly connected to the side of the convex plate 72 near the movable half-hoop 73. Inserting the rear end of the protective tube between the movable half-hoops 73 can prevent the protective tube from shifting or tilting during grinding, thus affecting the grinding accuracy. When the protective tube needs to be disassembled, simply push the two movable half-hoops 73 to the sides to open them, thereby ensuring that the protective tube remains stable and making it easy to remove after grinding. The elastic reset action of the elastic telescopic rod 74 causes the movable half-hoops 73 to automatically reset and fit, thereby clamping the rear end of the protective tube, improving the ease of use of the device. The movable limiting device 7 also includes a side gripper 75, which is hinged to the movable half-hoop 73. The outer arc surface of the semi-hoop 73 has a side gripper 75 for clamping the rear wall of the protective tube. The lower gripper 76 is hinged to the rear side of the sliding seat 71 and is also used to clamp the rear wall of the protective tube. The guide rail 77 is fixedly connected to both sides of the upper surface of the operating table 1 and is used to limit and guide the sliding seat 71. The connecting plate 78 is fixedly connected to the rear side of the movable bracket 5. A torsion spring is provided at the hinge between the side gripper 75 and the movable semi-hoop 73, and a torsion spring is provided at the hinge between the lower gripper 76 and the sliding seat 71. The spring, the free end of the elastic telescopic rod 74 away from the convex plate 72 is fixedly connected to the convex plate 72, the lower surface of the sliding seat 71 is slidably connected to the outer surface of the guide rail 77, the rear end of the connecting plate 78 is fixedly connected to the front side of the sliding seat 71, the side clamp 75 and the lower clamp 76 are flipped open, the protective tube is inserted and then the side clamp 75 and the lower clamp 76 are moved, the elastic reset action of the torsion spring drives the side clamp 75 and the lower clamp 76 to reset and clamp the rear end wall of the protective tube, further improving the stability of the protective tube during grinding.

[0054] Working principle: The rear end of the protective tube is placed on the sliding seat 71, making it flush with the grinding bracket 2. The rear end of the protective tube is inserted between the movable half-hoops 73 to prevent it from shifting or tilting during grinding, thus affecting grinding accuracy. When the protective tube needs to be removed, simply push the two movable half-hoops 73 to the sides to open them. This ensures the protective tube remains stable while facilitating its removal after grinding. After the movable half-hoops 73 slide to the sides on the sliding seat 71, they compress the elastic telescopic rod 74, causing it to contract between the movable half-hoops 73 and the convex plate 72. After releasing the movable half-hoops 73, the elastic telescopic rod 74 releases its elasticity. The reset action causes the movable half-clamp 73 to automatically reset and fit, thereby clamping the rear end of the protective tube, improving the ease of use of the device. Before inserting the protective tube into the movable half-clamp 73, the side clamp 75 and the lower clamp 76 are flipped open. After inserting the protective tube, the side clamp 75 and the lower clamp 76 are moved. The elastic reset action of the torsion spring causes the side clamp 75 and the lower clamp 76 to reset and clamp the rear end of the protective tube wall, further improving the stability of the protective tube during grinding. When the moving bracket 5 moves backward, it drives the connecting plate 78 to move backward. The connecting plate 78 drives the sliding seat 71 to slide backward on the operating table 1 and the guide rail 77. The sliding seat 71 then drives the rear end of the protective tube to move, thereby driving the entire protective tube to move.

[0055] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the chip collection device 8 includes a receiving groove 81, which is formed on the upper surface of the operating table 1. The receiving groove 81 is used to contact the chips that splash down during grinding. The guide plate 82 is fixedly connected to the side of the connecting plate 78 away from the linear motor 3. The baffle 83 is fixedly connected to the upper surface of the connecting plate 78. The baffle 83 is used to block the chips that splash to both sides of the device. The chips splash down or fall along the surface of the protective tube into the receiving groove 81, thereby preventing the chips from splashing outside the device and being difficult to remove. The chips that splash to the side of the protective tube are then blocked by the baffle 83 and fall onto the connecting plate 78 and the guide plate 82, and then slide down the inclined surface of the guide plate 82 into the receiving groove 81, further preventing the chips from flying out and affecting the working environment. The chip collection device 8 also includes a connector 84, which is fixedly connected to On the inclined surface of the guide plate 82, a push plate 85 is fixedly connected to the bottom end of the connector 84. The push plate 85 is used to push and collect the debris in the receiving groove 81. The discharge channel 86 is opened on the inner surface of the receiving groove 81. The collection frame 87 is fixedly connected to the lower surface of the operating table 1. A cover plate 88 is hinged to the front side of the collection frame 87. The push plate 85 and the inner surface of the receiving groove 81 are slidably connected. The guide plate 82 and the upper surface of the operating table 1 abut against each other. The push plate 85 contacts the inner wall of the receiving groove 81 and scrapes off the debris adhering to the inner wall of the receiving groove 81 and pushes it backward to the discharge channel 86. The debris falls downward into the collection frame 87 for collection, which is convenient for the staff to handle later and improves work efficiency and operation convenience. When the debris falls into the collection frame 87, it is blocked by the cover plate 88 and cannot be discharged. Opening the cover plate 88 can quickly remove the debris from the collection frame 87.

[0056] Working principle: When grinding the surface of the protective tube produces debris, the debris splashes off or falls along the surface of the protective tube into the receiving groove 81, thus preventing debris from splashing outside the device and being difficult to remove. Debris splashing to the side of the protective tube is blocked by the baffle 83 and then falls onto the connecting plate 78 and the guide plate 82, then slides down the inclined surface of the guide plate 82 into the receiving groove 81, further preventing debris from flying out and affecting the working environment. When the connecting plate 78 moves backward, it drives the connecting piece 84 to move backward, and the connecting piece 84 drives the push plate 8... 5. Slide backward within the receiving groove 81. The push plate 85 contacts the inner wall of the receiving groove 81, scraping off the debris adhering to the inner wall of the receiving groove 81 and pushing it backward. When the push plate 85 pushes the debris onto the discharge channel 86, the debris falls downward into the collection frame 87 for collection, facilitating subsequent processing by the staff and improving work efficiency and ease of operation. When the debris falls into the collection frame 87, it is blocked by the cover plate 88 and cannot be discharged. Opening the cover plate 88 allows the debris to be quickly removed from the collection frame 87.
