Description

Technical Field

[0001] This invention belongs to the field of cable protection pipe welding technology, specifically relating to a cable protection pipe butt welding device. Background Technology

[0002] Cable protection pipe welding is a key process in underground power installations to achieve sealed pipe connections and ensure the safety of internal cables. Traditional welding often produces weld beads on the inner wall at the joint, hindering cable installation. Modern technology uses precision beveling and CNC hot-melt welding equipment to ensure that the weld beads are integrated into the pipe wall without protruding from the inner cavity. Combined with automatic clamping and grinding devices, it achieves high sealing performance and a smooth, flat joint quality.

[0003] Patent CN117921265A relates to a cable protection pipe butt welding device, covering the field of cable protection pipe welding processing. It includes an automatic welding unit with a U-shaped base at its front. The automatic welding unit includes an automatic welding machine with an automatic rotating welding head at its front. A clamping and feeding unit and a connecting pipe fixing unit are located on the upper end of the U-shaped base. By using the clamping and connecting pipe fixing units to fix the middle of the cable protection pipe and the connecting pipe at multiple points, it can not only stably and forcefully clamp the cable protection pipe but also ensure smooth and stable butt welding of the cable protection pipe subsequently. This improves welding alignment accuracy and quality, reduces manual intervention, saves time and labor, and avoids the instability and inaccuracy that occur when manually supporting the cable protection pipe and connecting pipe, greatly improving welding efficiency. Although this device solves the aforementioned problems, there is still a possibility that if the diameter of the welding pipe is too large, it may be difficult to clamp it completely, leading to incomplete welding or weak welds. Summary of the Invention

[0004] The purpose of this invention is to provide a cable protection pipe butt welding device to solve the problem of incomplete welding caused by excessively large pipe diameter during the welding process.

[0005] To achieve the above objectives, the present invention provides a cable protection pipe butt welding device, including a frame: a tension column is fixedly connected to the top of the frame, a device plate is provided on the top of the tension column, a fixed frame is provided on the top of the frame, a maintenance mechanism is provided on the inner wall of the tension column, and a temperature detection mechanism is provided on the inner wall of the maintenance mechanism. The fixed structure includes a limiting chamber, a bidirectional screw, a knob, a left movable block, a right movable block, and a clamping wheel. The limiting chamber is fixedly connected to the top of the frame. The bidirectional screw is rotatably connected to the inner wall of the limiting chamber. The knob is fixedly connected to the outer wall of the bidirectional screw. The left movable block is movably connected to the outer circumferential surface of the bidirectional screw. The right movable block is movably connected to the outer circumferential surface of the bidirectional screw. The clamping wheel is fixedly connected to the top of the left movable block. A motor is provided on the outer wall of the clamping wheel. The left movable block is slidably connected to the limiting chamber.

[0006] In one possible implementation, the fixed structure further includes a sliding rail, a transverse wheel, a movable cabin, a telescopic frame, and a top plate. The sliding rail is fixedly connected to the outer wall of the frame base, the transverse wheel is slidably connected to the top of the sliding rail, the movable cabin is fixedly connected to the top of the transverse wheel, the telescopic frame is slidably connected to the inner wall of the movable cabin, and the top plate is fixedly connected to the top of the telescopic frame.

[0007] In one possible implementation, the fixing structure further includes a top wheel, a rubber ring, a vertical slide rod, a helical rod, and a movable block. The top wheel is rotatably connected to the top of the top plate, the rubber ring is fixedly connected to the outer circumferential surface of the clamping wheel, the vertical slide rod is slidably connected to the inner wall of the extension column, the helical rod is rotatably connected to the inner wall of the vertical slide rod, the movable block is movably connected to the outer circumferential surface of the helical rod, and the movable block is slidably connected to the inner wall of the vertical slide rod. The rubber ring contacts the protective tube, and the friction causes the protective tube to rotate. The rotation of the rubber ring, together with the knob, supports and fixes the top of the protective tube, so that cable protective tubes of different sizes can be fully clamped, avoiding the occurrence of incomplete or false welds during the welding process due to the protective tube being too large in diameter.

[0008] In one possible implementation, the peacekeeping mechanism includes a telescopic rod, a base plate, and a barrier surface. The telescopic rod is fixedly connected to the bottom of the movable block, the base plate is fixedly connected to the bottom of the telescopic rod, and the barrier surface is fixedly connected to the bottom of the base plate.

[0009] In one possible implementation, the peacekeeping mechanism further includes a rotary dial, a welding head, and an angled surface. The rotary dial is rotatably connected to the inner wall of the barrier surface, the welding head is fixedly connected to the bottom of the base plate and contacts the bottom pipe, and the angled surface is fixedly connected to the inner wall of the limiting chamber and is slidably connected to the clamping wheel.

[0010] In one possible implementation, the peacekeeping mechanism further includes a waste drawer, a moisture chamber, and absorbent cotton. The waste drawer is slidably connected to the inner wall of the limiting chamber, the moisture chamber is fixedly connected to the inner wall of the vertical slide rod, and the absorbent cotton is slidably connected to the inner wall of the moisture chamber. The absorbent cotton and the moisture chamber are connected by a spring, and the absorbent cotton is located on the movement trajectory of the welding head. To avoid the above situation, the welding slag falling from the top will be blocked by the beveled surface, preventing the welding slag from directly contacting the bidirectional screw. Subsequently, the welding slag will be guided by the beveled surface to fall into the inside of the waste drawer, thereby preventing the welding slag from getting stuck inside the core components and affecting the normal operation of the device. At the same time, it also makes it easier for manual collection and unified treatment of the welding slag.

[0011] In one possible implementation, the temperature detection mechanism includes an L-shaped base and an indicator needle. The L-shaped base is fixedly connected to the bottom of the absorbent cotton, the indicator needle is fixedly connected to the inner wall of the L-shaped base, the L-shaped base is slidably connected to the humidity chamber, and the L-shaped base is slidably connected to the stretching column.

[0012] In one possible implementation, the temperature detection mechanism further includes a scale and a temperature guide rod. The scale is located on the outer wall of the stretching column, and the temperature guide rod is fixedly connected to the top of the movable block. The temperature guide rod is slidably connected to the vertical slide rod.

[0013] In one possible implementation, the temperature detection mechanism further includes a temperature-conducting plate and a temperature-measuring rod. The temperature-conducting plate is fixedly connected to the bottom of the temperature-conducting rod, and the temperature-measuring rod is fixedly connected to the inner wall of the temperature-conducting rod. The temperature-conducting plate is slidably connected to the movable block, and the temperature-conducting plate is in contact with the welding head. During operation, the temperature of the welding head is absorbed by the temperature measuring rod through the conduction of the temperature conducting plate and the temperature conducting rod. The temperature of the welding head is then displayed by the temperature measuring rod, allowing the staff to intuitively observe the temperature scale displayed on the temperature measuring rod. When the welding head temperature is too high during long-term operation, the staff can stop the operation of the device in time.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, with the cooperation of a bidirectional screw, a limiting chamber, and a clamping wheel, the rotation of the bidirectional screw drives the right and left movable blocks to converge towards the center under the limitation of the limiting chamber through the spiral groove on the circumferential surface. Then, the rotation of the clamping wheel drives the rubber ring to rotate. The rubber ring contacts the protective tube and drives the protective tube to rotate through friction. The rotation of the rubber ring, together with the knob, supports and fixes the top of the protective tube, so that cable protective tubes of different sizes can be completely clamped, avoiding the situation where the diameter of the protective tube is too large during the welding process, which may cause incomplete welding or false welding.

[0015] 2. With the cooperation of the welding head, absorbent cotton, and spiral rod, when the device is not in use, the spiral rod rotates and drives the movable block to move into the interior of the absorbent cotton through the spiral groove on the circumferential surface. The movement of the movable block drives the welding head to move towards the absorbent cotton, so that the welding head is stored inside the absorbent cotton when not in use. When not in use, the absorbent cotton is in contact with the welding head, thereby protecting the welding head from impacts, enabling the welding head to quickly insulate and extend its service life.

[0016] 3. With the cooperation of the welding head and the temperature measuring rod, the temperature of the welding head will be absorbed by the temperature measuring rod through the conduction of the temperature conducting plate and the temperature conducting rod during the operation of the device. Then the temperature of the welding head will be displayed by the temperature measuring rod, which allows the staff to intuitively observe the temperature scale displayed on the temperature measuring rod. When the welding head temperature is too high during long-term operation of the device, the operation of the device can be stopped in time by the operator. Attached Figure Description

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-8 As shown, one embodiment of the present invention is: a cable protection pipe butt welding device, including a frame 1: a tension column 2 is fixedly connected to the top of the frame 1, a device plate 3 is provided on the top of the tension column 2, a fixed frame 4 is provided on the top of the frame 1, a maintenance mechanism 5 is provided on the inner wall of the tension column 2, and a temperature detection mechanism 6 is provided on the inner wall of the maintenance mechanism 5. The fixed structure 4 includes a limiting chamber 401, a bidirectional screw 402, a knob 403, a left movable block 404, a right movable block 405, and a clamping wheel 406. The limiting chamber 401 is fixedly connected to the top of the frame 1. The bidirectional screw 402 is rotatably connected to the inner wall of the limiting chamber 401. The knob 403 is fixedly connected to the outer wall of the bidirectional screw 402. The left movable block 404 is movably connected to the outer circumferential surface of the bidirectional screw 402. The right movable block 405 is movably connected to the outer circumferential surface of the bidirectional screw 402. The clamping wheel 406 is fixedly connected to the top of the left movable block 404. A motor is provided on the outer wall of the clamping wheel 406. The left movable block 404 is slidably connected to the limiting chamber 401.

[0021] The fixed structure 4 also includes a sliding rail 407, a horizontal wheel 408, a moving cabin 409, a telescopic frame 410, and a top plate 411. The sliding rail 407 is fixedly connected to the outer wall of the frame 1, the horizontal wheel 408 is slidably connected to the top of the sliding rail 407, the moving cabin 409 is fixedly connected to the top of the horizontal wheel 408, the telescopic frame 410 is slidably connected to the inner wall of the moving cabin 409, and the top plate 411 is fixedly connected to the top of the telescopic frame 410.

[0022] The fixed structure 4 also includes a top wheel 412, a rubber ring 413, a vertical slide rod 414, a spiral rod 415, and a movable block 416. The top wheel 412 is rotatably connected to the top of the top plate 411. The rubber ring 413 is fixedly connected to the outer circumferential surface of the clamping wheel 406. The vertical slide rod 414 is slidably connected to the inner wall of the extension column 2. The spiral rod 415 is rotatably connected to the inner wall of the vertical slide rod 414. The movable block 416 is movably connected to the outer circumferential surface of the spiral rod 415 and slidably connected to the inner wall of the vertical slide rod 414. The rotation of the bidirectional screw 402 drives the right movable block 405 and the left movable block 404 to converge towards the center under the limitation of the limiting chamber 401 through the spiral groove on the circumferential surface. Then, the clamping wheel 406 rotates, driving the rubber ring 413 to rotate. The rubber ring 413 contacts the protective tube and drives the protective tube to rotate through friction. The rotation of the rubber ring 413, together with the knob 504 supporting and fixing the top of the protective tube, can fully clamp cable protective tubes of different sizes, avoiding the occurrence of false welds or incomplete welds caused by the protective tube diameter being too large during the welding process.

[0023] The peacekeeping mechanism 5 includes a telescopic rod 501, a base plate 502, and a barrier surface 503. The telescopic rod 501 is fixedly connected to the bottom of the movable block 416, the base plate 502 is fixedly connected to the bottom of the telescopic rod 501, and the barrier surface 503 is fixedly connected to the bottom of the base plate 502.

[0024] The peacekeeping mechanism 5 also includes a rotary disk 504, a welding head 505, and an angled surface 506. The rotary disk 504 is rotatably connected to the inner wall of the barrier surface 503. The welding head 505 is fixedly connected to the bottom of the base plate 502 and contacts the bottom pipe. The angled surface 506 is fixedly connected to the inner wall of the limiting chamber 401 and is slidably connected to the clamping wheel 406.

[0025] The peacekeeping mechanism 5 also includes a waste drawer 507, a moisture chamber 508, and absorbent cotton 509. The waste drawer 507 is slidably connected to the inner wall of the limiting chamber 401, the moisture chamber 508 is fixedly connected to the inner wall of the vertical slide bar 414, and the absorbent cotton 509 is slidably connected to the inner wall of the moisture chamber 508. The absorbent cotton 509 and the moisture chamber 508 are connected by a spring, and the absorbent cotton 509 is located on the movement trajectory of the welding head 505. When the device is not in use, the rotating screw 415 drives the movable block 416 to move into the absorbent cotton 509 through the spiral groove on the circumferential surface. The movement of the movable block 416 drives the welding head 505 to move towards the absorbent cotton 509, so that the welding head 505 will be stored inside the absorbent cotton 509 when not in use. When not in use, the absorbent cotton 509 is in contact with the welding head 505, thereby protecting the welding head 505 from impacts, enabling the welding head 505 to quickly insulate and extend its service life.

[0026] Working principle: When using the device, first place the cable protection tube to be welded on top of the clamping wheel 406. Then, activate the movable block 416 to extend the telescopic rod 501. The extension of the telescopic rod 501 causes the bottom column plate 502 to move downward. The downward movement of the bottom column plate 502 causes the knob plate 504 to move downward, squeezing and fixing the cable outer tube. When the cable outer tube size is different, rotate the knob 403 to rotate the bidirectional screw 402. The rotation of the bidirectional screw 402, through the spiral groove on the circumferential surface, causes the right movable block 405 and the left movable block 404 to converge towards the center under the limitation of the limiting chamber 401. Then, the clamping wheel 406 rotates, causing the rubber ring 413 to rotate. The rubber ring 413 contacts the protection tube and, through friction, drives the protection tube to rotate. The tube rotates, and the rotation of the rubber ring 413, in conjunction with the knob 504, supports and fixes the top of the protective tube, ensuring that cable protective tubes of different sizes can be fully clamped. This prevents the protective tube diameter from being too large, which could lead to incomplete or false welds during the welding process. Before welding the protective tube, the movable cabin 409 moves the top telescopic frame 410, which in turn moves the top plate 411. The top plate 411 then moves the top wheel 412. When the top wheel 412 moves to the appropriate distance, it supports the rotating pipe during welding, preventing the protective tube from being too long and causing the weld to fail due to excessive weight at one end.

[0027] During the welding process of the protective tube, the rotary disc 504 presses against the completed weld seam, and the weld slag on the surface of the weld seam is then pressed off by the rotary disc 504. During this falling process, the weld slag can easily fall onto the circumferential surface of the bidirectional screw 402, causing jamming of core components such as the bidirectional screw 402 and potentially damaging the device. To prevent this, the weld slag falling from the top is blocked by the beveled surface 506, preventing direct contact between the weld slag and the bidirectional screw 402. The weld slag is then guided by the beveled surface 506 to fall into the waste drawer 507, thus preventing the weld slag from getting stuck in the core components. Inside, it affects the normal operation of the device, and at the same time, it facilitates the manual collection and unified treatment of welding slag. When the device is not in use, the rotating screw rod 415 drives the movable block 416 to move into the water-absorbing cotton 509 through the spiral groove on the circumferential surface. The movement of the movable block 416 drives the welding head 505 to move towards the water-absorbing cotton 509, so that the welding head 505 will be stored inside the water-absorbing cotton 509 when it is not in use. When not in use, the water-absorbing cotton 509 contacts the welding head 505, thereby protecting the welding head 505 from bumps and making the welding head 505 quickly insulated and heat-insulated, thus extending the service life of the welding head 505.

[0028] like Figures 1-8As shown, in another embodiment of the present invention based on the above embodiments, the temperature detection mechanism 6 includes an L-shaped base 601 and an indicator needle 602. The L-shaped base 601 is fixedly connected to the bottom of the absorbent cotton 509, and the indicator needle 602 is fixedly connected to the inner wall of the L-shaped base 601. The L-shaped base 601 is slidably connected to the humidity chamber 508 and to the stretching column 2.

[0029] The temperature detection mechanism 6 also includes a scale 603 and a temperature guide rod 604. The scale 603 is opened on the outer wall of the stretching column 2, and the temperature guide rod 604 is fixedly connected to the top of the movable block 416. The temperature guide rod 604 is slidably connected to the vertical slide rod 414.

[0030] The temperature detection mechanism 6 also includes a temperature-conducting plate 605 and a temperature-measuring rod 606. The temperature-conducting plate 605 is fixedly connected to the bottom of the temperature-conducting rod 604, and the temperature-measuring rod 606 is fixedly connected to the inner wall of the temperature-conducting rod 604. The temperature-conducting plate 605 is slidably connected to the movable block 416, and the temperature-conducting plate 605 is in contact with the welding head 505. During operation, the temperature on the welding head 505 is conducted through the temperature conducting plate 605 and the temperature conducting rod 604 and absorbed by the temperature measuring rod 606. Subsequently, the temperature of the welding head is displayed by the temperature measuring rod 606, allowing the staff to intuitively observe the temperature scale displayed on the temperature measuring rod 606. When the temperature of the welding head 505 is too high during long-term operation, the staff can stop the operation of the device in time.

[0031] Working principle: When not in use, the welding head 505 is wrapped inside the absorbent cotton 509. The internal moisture cools the welding head 505. When the absorbent cotton 509 is sufficiently moist, its weight compresses the bottom spring, causing it to move downwards. This downward movement of the absorbent cotton 509 moves the L-shaped base 601 downwards, which in turn moves the indicator needle 602 downwards. The indicator needle 602 then points to the value on the scale 603, allowing operators to visually monitor the moisture content inside the absorbent cotton 509. This enables timely addition of protective fluid to the absorbent cotton 509 and maintain the surface of the welding head 505. During operation, the temperature of the welding head 505 is conducted through the temperature-conducting plate 605 and the temperature-conducting rod 604 and absorbed by the temperature-sensing rod 606. The welding head temperature is then displayed on the temperature-sensing rod 606, allowing operators to visually observe the temperature scale. If the temperature of the welding head 505 becomes too high during prolonged operation, operators can promptly stop the device.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
