Description

Technical Field

[0001] This invention belongs to the field of pipeline docking technology, specifically referring to an auxiliary docking device for pipeline welding. Background Technology

[0002] Pipelines are devices specifically designed for transporting gases, liquids, or fluids containing solid particles, and their applications are extremely wide-ranging. Specifically, pipelines are mainly used in water supply systems, drainage systems, heating systems, gas supply systems, as well as long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering projects, and various industrial installations. Welding is an essential step in the use of pipelines, and pipe butt welding, as the core and fundamental step in the welding process and even the entire pipeline system engineering, is of paramount importance.

[0003] The existing auxiliary docking equipment for pipe welding has the following problems:

[0004] Existing auxiliary welding equipment for pipe welding lacks the ability to grind the end faces of pipes before welding, resulting in large gaps between pipes after welding, which affects the welding effect. In addition, it lacks the ability to dry the surface of the pipe joint, which affects the welding quality.

[0005] Therefore, it cannot meet the existing demand for auxiliary docking equipment for pipe welding. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this solution provides an auxiliary pipe welding device that can grind the end face of the pipe before pipe docking, improve the smoothness of the pipe docking end face, reduce the splicing gap, and keep the pipe docking area and surrounding surface dry, thereby improving the welding quality.

[0007] The technical solution adopted in this proposal is as follows: This proposal provides an auxiliary docking device for pipe welding, comprising a docking platform, a support frame, a feeding-type assembly mechanism, and a heat-conducting grinding end mechanism. The support frame is located on both sides of the docking platform. The feeding-type assembly mechanism is located on the upper wall of the docking platform. The heat-conducting grinding end mechanism is located in the middle of the upper wall of the docking platform. The feeding-type assembly mechanism includes a clamping component, a driving component, and a pushing component. The clamping components are symmetrically located on the upper walls at both ends of the docking platform. The driving components are symmetrically located on the bottom walls at both ends of the docking platform. The pushing component is located on the bottom wall of the docking platform near the driving component. The heat-conducting grinding end mechanism includes a heat dissipation component, a guiding component, a sliding component, a grinding component, and a sensing component. The heat dissipation component is located inside the clamping component. The guiding component is located on the side wall of the heat dissipation component. The sliding component is located in the middle of the upper wall of the docking platform. The grinding component is located on both sides of the sliding component. The sensing component is located on the inner side wall of the grinding component.

[0008] As a further preferred embodiment of the present invention, the clamping assembly includes a clamping frame and clamping bolts. The clamping frame is symmetrically arranged on the upper walls at both ends of the docking platform, and multiple sets of clamping bolts are threaded through the side walls of the clamping frame and connected to the clamping frame. The driving assembly includes a driving motor, a support block, and a threaded rod. The driving motor is symmetrically arranged on the bottom walls at both ends of the docking platform, the support block is located on the bottom wall of the docking platform on one side of the driving motor, and the threaded rod is threaded through the support block and located at the power end of the driving motor. The threaded rod is rotatably connected to the support block. The pushing assembly includes a sliding groove and a pushing plate. The sliding groove is symmetrically arranged on the bottom walls of the docking platform on both sides of the support block, and the pushing plate is located between the sliding groove and the threaded rod. The pushing plate is slidably connected to the sliding groove and threadedly connected to the threaded rod.

[0009] In use, the drive motor drives the threaded rod to rotate, which in turn causes the pusher plate to slide along the slide groove away from the docking platform. Rotating the clamping bolt causes it to rotate along the threads of the clamping frame, causing the adapter blocks to move in opposite directions. The adapter blocks increase the distance between the arc-shaped copper plates, and the fixing block slides along the arc-shaped copper plates to a position close to the clamping bolt. The pipe to be docked is then inserted into the clamping frame, with one end of the pipe fitting against the pusher plate and the other end against the bottom wall of the clamping frame. Rotating the clamping bolt causes it to move the arc-shaped copper plates relative to each other via the adapter blocks. The arc-shaped copper plates cause the fixing block to fit against the pipe surface, thus fixing the pipe. The drive motor then reverses the rotation of the threaded rod, causing it to slide along the slide groove. The pusher plate moves the pipe relative to each other until the pipe ends fit together, completing the docking operation before welding.

[0010] Preferably, the heat dissipation assembly includes an arc-shaped copper plate, a fixing block, and an adapter block. The adapter block is rotatably disposed on the side of the clamping bolt near the clamping frame. The arc-shaped copper plate is slidably disposed on the side of the adapter block away from the clamping bolt. The fixing block is slidably disposed on the side of the arc-shaped copper plate away from the adapter block. The sliding assembly includes a sliding plate, a linear motor, and a lifting frame. The sliding plate is symmetrically disposed on the inner sidewalls of both ends of the docking platform. The linear motor is disposed on the sidewall of the sliding plate. The lifting frame is disposed between the power ends of the linear motor. The guiding assembly includes a heat-resistant magnetic block, a guiding spring, and a guiding electromagnet. The heat-resistant magnetic block is disposed on the sidewall of the arc-shaped copper plate away from the clamping frame. The guiding spring is disposed between the heat-resistant magnetic block and the clamping frame. The guiding electromagnet is symmetrically disposed on both sides of the lifting frame. The grinding assembly includes a grinding sleeve, a grinding column, a grinding spring, an abrasive disc, an annular grinding layer, and a motor slot. The grinding motor and drive frame are configured as follows: the grinding sleeve is symmetrically arranged on both sides of the lifting frame; the grinding column is slidably arranged at the end of the grinding sleeve away from the lifting frame; the abrasive disc is rotatably arranged on the side of the grinding column away from the grinding sleeve; the grinding spring is arranged between the abrasive disc and the lifting frame on the outside of the grinding sleeve and grinding column, and the grinding spring is rotatably connected to the lifting frame through a turntable; the annular grinding layer is arranged on the side of the abrasive disc away from the grinding column, and the inner and outer diameters of the annular grinding layer are both larger than the inner and outer diameters of the pipe; the motor slot is arranged between the abrasive disc and the grinding column; the grinding motor is arranged inside the motor slot and fixedly connected to the grinding column; the drive frame is arranged between the power end of the grinding motor and the abrasive disc; the sensing component includes a proximity switch and an annular electromagnet; the proximity switch is arranged on the inner wall of the grinding sleeve near the lifting frame; and the annular electromagnet is arranged on the inner wall of the grinding sleeve outside the proximity switch.

[0011] In operation, the linear motor drives the lifting frame to rise. The lifting frame, through the grinding sleeve and grinding column, drives the abrasive disc to rise. The abrasive disc drives the annular grinding layer to a position coaxial with the pipe. The grinding motor, through its power end, drives the drive frame to rotate. The drive frame, through the abrasive disc, drives the annular grinding layer to rotate. The pusher plate pushes the pipe forward. The pipe slides along the arc-shaped copper plate through the fixed block and comes into contact with the annular grinding layer. The high-speed rotating annular grinding layer grinds the end face of the pipe that is about to be connected, improving the tightness of the pipe connection. As the pusher plate advances the pipe, it increases the contact force between the pipe end face and the annular grinding layer. After being squeezed by the pipe, the annular grinding layer uses the deformation of the grinding spring to drive the grinding column to slide along the grinding sleeve. When the pipe exceeds the arc-shaped copper plate... When the plate is wrapped around the pipe, the guide electromagnet is energized to generate magnetism (with opposite poles to the heat-resistant magnetic block). Since the guide electromagnet is fixed to the side wall of the lifting frame, it attracts the heat-resistant magnetic block through magnetic force. The heat-resistant magnetic block, with the help of the deformation of the guide spring, drives the arc-shaped copper plate to slide along the transition block, ensuring that the arc-shaped copper plate is always in contact with the outside of the pipe. The gap between the arc-shaped copper plate and the pipe surface is small, and the heat conduction speed of the arc-shaped copper plate is faster than that of the pipe. The heat generated during the grinding process will preferentially flow into the interior of the arc-shaped copper plate, which acts as a "heat-absorbing bridge", and quickly spread along its length, thereby reducing the temperature of the grinding point, avoiding burns in the pipe grinding area, and heating the far end of the pipe, preheating the area to be welded and the surrounding pipe, and keeping the area dry.

[0012] When the proximity switch senses the grinding column, the annular electromagnet is energized and becomes magnetic. The annular electromagnet uses magnetic force to attract the grinding column. Under the deformation of the grinding spring, the grinding column quickly moves the annular grinding layer away from the pipe end face. The linear motor drives the lifting frame to descend through the power end. The lifting frame moves the annular grinding layer away from the docking area of ​​the pipe. At this time, the heat-resistant magnetic block loses the magnetic attraction force of the guiding electromagnet. The deformation of the guiding spring drives the arc-shaped copper plate to reset. As the push plate advances the pipe at a uniform speed, the ground pipe end face is precisely aligned. The drive motor stops driving the threaded rod to rotate, completing the docking of the pipe.

[0013] Specifically, a controller is provided on the side wall of the docking platform.

[0014] The controller is electrically connected to the drive motor, the guide electromagnet, the linear motor, the grinding motor, the proximity switch, and the ring electromagnet.

[0015] The beneficial effects achieved by this solution using the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a feeding-type splicing mechanism with a heat-conducting grinding mechanism. Through the inclusion of clamping, driving, pushing, heat dissipation, guiding, sliding, grinding, and sensing components, it can grind the pipe's mating end faces during the pipe connection process. This corrects inherent defects such as non-perpendicularity and unevenness of the pipe's end faces, reduces the pipe connection gap, and ensures welding quality. Furthermore, by utilizing an arc-shaped copper plate as a "heat-absorbing bridge," it lowers the grinding temperature of the pipe end faces while ensuring the dryness of the pipe connection area and surrounding environment, thus protecting the pipe... The grinding effect improves the pipe connection effect. The heat-resistant magnetic block uses the deformation of the guide spring to drive the arc-shaped copper plate to slide along the transition block, so that the arc-shaped copper plate always stays on the outside of the pipe. The distance between the arc-shaped copper plate and the pipe surface is small, and its heat conduction speed is better than that of the pipe. The heat generated during the grinding process will preferentially flow into the interior of the arc-shaped copper plate, which acts as a 'heat-absorbing bridge', and quickly spread along its length. This not only reduces the temperature at the grinding point and avoids burns in the pipe grinding area, but also heats the far end of the pipe, preheats the area to be welded and the surrounding pipe, and keeps the area dry, thereby improving the welding quality of the pipe.

The motor 37 and drive frame 38 are included. The grinding sleeve 27 is symmetrically arranged on both sides of the lifting frame 25. The grinding column 28 is slidably disposed at the end of the grinding sleeve 27 away from the lifting frame 25. The abrasive disc 30 is rotatably disposed on the side of the grinding column 28 away from the grinding sleeve 27.

The annular grinding layer 35 is disposed on the side of the abrasive disc 30 away from the grinding column 28, and the annular grinding layer... The inner and outer diameters of layer 35 are both larger than the inner and outer diameters of the pipe. The motor slot 36 is located between the abrasive disc 30 and the grinding column 28. The grinding motor 37 is located inside the motor slot 36 and is fixedly connected to the grinding column 28. The drive frame 38 is located between the power end of the grinding motor 37 and the abrasive disc 30. The sensing component 31 includes a proximity switch 32 and an annular electromagnet 33. The proximity switch 32 is located on the inner wall of the grinding sleeve 27 near the lifting frame 25. The annular electromagnet 33 is located on the inner wall of the grinding sleeve 27 outside the proximity switch 32.

[0035] The docking platform 1 is equipped with a controller 34 on its side wall.

[0036] The controller 34 is electrically connected to the drive motor 8, the guide electromagnet 21, the linear motor 24, the grinding motor 37, the proximity switch 32, and the ring electromagnet 33, respectively.

[0037] In actual use, in the initial state, the guide spring 20 is in a compressed state, the grinding spring 29 is in a naturally extended state, the controller 34 controls the linear motor 24 to start, the power end of the linear motor 24 drives the lifting frame 25 to rise, the lifting frame 25 drives the abrasive disc 30 to rise through the grinding sleeve 27 and the grinding column 28, and the abrasive disc 30 drives the annular grinding layer 35 to rise to a position that is coaxial and horizontal with the end of the push plate 13 away from the threaded rod 10.

[0038] The controller 34 controls the drive motor 8 to start, and the drive motor 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the push plate 13 to slide along the slide groove 12 to the side away from the docking table 1. The clamping bolt 6 is rotated, and the clamping bolt 6 rotates along the thread of the clamping frame 5, which drives the adapter block 39 to move in opposite directions. The adapter block 39 drives the distance between the two arc-shaped copper plates 16 to increase. The fixing block 17 slides along the arc-shaped copper plate 16 to a position close to the clamping bolt 6, and inserts the pipe to be docked into the clamping frame 5. One end of the pipe is in contact with the push plate 13, and the other end is in contact with the bottom wall of the clamping frame 5. The clamping bolt 6 is rotated, and the clamping bolt 6 drives the arc-shaped copper plate 16 to move relative to each other through the adapter block 39. The arc-shaped copper plate 16 drives the fixing block 17 to contact the surface of the pipe, thus fixing the pipe.

[0039] The controller 34 controls the grinding motor 37 to start. The grinding motor 37 drives the drive frame 38 to rotate through the power end. The drive frame 38 drives the annular grinding layer 35 to rotate through the abrasive disc 30. The controller 34 controls the drive motor 8 to drive the threaded rod 10 to reverse. The threaded rod 10 drives the push plate 13 to slide along the slide groove 12. The push plate 13 drives the pipe to move relative to each other. The pipe slides along the arc-shaped copper plate 16 through the fixed block 17 and fits against the annular grinding layer 35. The high-speed rotating annular grinding layer 35 grinds the end face of the pipe that is about to be connected. As the push plate 13 pushes the pipe, the contact force between the pipe end face and the annular grinding layer 35 gradually increases. After being squeezed by the pipe, the annular grinding layer 35 uses the deformation of the grinding spring 29 to drive the grinding column 28 to slide along the grinding sleeve 27.

[0040] When the pipe extends beyond the coverage of the arc-shaped copper plate 16, the controller 34 activates the guide electromagnet 21. The guide electromagnet 21 is energized and generates magnetism. The guide electromagnet 21 and the heat-resistant magnetic block 19 are set with opposite poles. The guide electromagnet 21 is fixed to the side wall of the lifting frame 25 and magnetically attracts the heat-resistant magnetic block 19. The heat-resistant magnetic block 19 uses the deformation of the guide spring 20 to drive the arc-shaped copper plate 16 to slide along the transition block 39, so that the arc-shaped copper plate 16 is always kept on the outside of the pipe. A certain distance is maintained between the arc-shaped copper plate 16 and the annular grinding layer 35. Since the distance between the arc-shaped copper plate 16 and the pipe surface is small, and the heat conduction speed of the arc-shaped copper plate 16 is faster than that of the pipe, the heat generated during the grinding process preferentially flows into the interior of the arc-shaped copper plate 16, which acts as a "heat-absorbing bridge", and is quickly transferred and diffused along its length, thereby reducing the temperature of the grinding point, avoiding burns in the grinding area of ​​the pipe, and heating the far end to keep the welding area of ​​the pipe and its surroundings dry.

[0041] As the pipeline continues to advance, the grinding column 28 retracts into the grinding sleeve 27. When the proximity switch 32 senses the grinding column 28, the controller 34 controls the annular electromagnet 33 to start. The annular electromagnet 33 is energized and generates magnetism. The annular electromagnet 33 uses magnetic force to attract the grinding column 28. Under the deformation of the grinding spring 29, the grinding column 28 quickly moves the annular grinding layer 35 away from the pipeline end face. At the same time, the controller 34 controls the linear motor 24 to start. The linear motor 24 drives the lifting frame 25 to descend through the power end. The lifting frame 25 moves the annular grinding layer 35 away from the docking area of ​​the pipeline. The controller 34 controls the guide electromagnet 21 to be de-energized and demagnetized. At this time, the heat-resistant magnetic block 19 loses the magnetic attraction force of the guide electromagnet 21. The guide spring 20 deforms and drives the arc-shaped copper plate 16 to reset. The push plate 13 continues to advance the pipeline at a uniform speed, so that the ground pipeline end face is precisely aligned. The controller 34 controls the drive motor 8 to stop running, and the threaded rod 10 stops rotating synchronously, completing the docking of the pipeline. The above steps can be repeated for the next use.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this.
