Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline welding, and particularly relates to a welding equipment for a water conservancy pipeline support. BACKGROUND

[0002] Various pipelines are widely used in water conservancy projects to collect, transport, distribute and regulate water resources. The pipelines are connected in various ways, and welding is one of the most common connection methods, which can provide a firm connection effect.

[0003] When welding the pipelines, it is crucial to ensure that the two pipelines are in a coaxial position, which requires centering the two pipelines. However, the prior art cannot simultaneously rotate the two pipelines after centering them, which requires workers to drill into the lower part of the pipeline for welding, which is inconvenient. Moreover, the pipelines need to be chamfered on both sides during the welding process, which requires switching between the chamfering equipment and the welding equipment, resulting in low welding efficiency.

[0004] Therefore, there is a need for a welding equipment for a water conservancy pipeline support to solve the technical problems of the prior art, such as the inability to simultaneously rotate the two pipelines after centering them and the need to replace equipment, resulting in low welding efficiency. SUMMARY

[0005] To overcome the defects of the prior art, the present application provides a welding equipment for a water conservancy pipeline support. During the welding process, the welding machine utilizes the force of the movement direction close to the two pipelines to flip the chamfering knife and the welding machine, ensuring the independence and non-interference of the welding and chamfering operations. This allows the work flow of chamfering first and then welding to be smoothly implemented without the need to replace equipment during the welding process, solving the technical problem of low welding efficiency caused by the need to replace equipment in the prior art. The high-pressure airflow drives the chamfering knife to chamfer the two pipelines. The high-pressure airflow not only cools the chamfering knife but also effectively blows off debris. After welding is completed, the high-pressure airflow drives the chamfering knife to remove burrs from the weld and cools the weld. The high-pressure airflow drives the two fixed tooth columns to rotate. Through the tooth engagement method, the connection barrels on both sides can rotate synchronously, thereby achieving synchronous fixation and rotation of the two pipelines. The synchronization between the two pipelines during chamfering and welding solves the technical problem of the prior art, which cannot simultaneously rotate the two pipelines after centering them.

The side wall of the transmission housing is fixedly connected to the side wall of the lifting bracket. The transmission housing is hollow. The input end of the transmission housing is connected to the output end of the air pump through an air pipe. The side wall of the transmission impeller is rotatably connected to the inner side wall of the transmission housing. The side wall of the transmission drive gear is rotatably connected to the side wall of the transmission housing. The side wall of the transmission drive gear and the side wall of the transmission impeller are coaxially fixedly connected. The support rod is symmetrically fixedly connected to both sides of the top wall of the base. A transmission shaft is rotatably connected to the support rod on both sides. A fixed gear column is coaxially fixedly connected to both ends of the transmission shaft. One outer edge of the fixed gear column is inclined. The driven gear is fixedly connected to the transmission shaft. The driven gear meshes with the transmission drive gear.

[0010] Preferably, the pipe fixing assembly includes a support frame symmetrically fixedly connected to the top wall of the push plate.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] 1. This application utilizes a movable pneumatic telescopic rod to move the welding machine, achieving the rotation of the chamfering blade and the welding machine, ensuring the independence and non-interference between welding and chamfering. The high-pressure airflow drives the chamfering blade to rotate, chamfering the pipes on both sides, increasing the welding area and reducing welding defects. The high-pressure airflow can also blow away the waste generated during chamfering and air-cool the chamfering blade. After welding, it can also remove the burrs of the weld and cool the weld. The high-pressure airflow drives the fixed toothed columns on both sides to rotate, and through tooth meshing, it drives the connecting cylinders on both sides to rotate synchronously, synchronously fixing the pipes on both sides and synchronously rotating the pipes, ensuring the synchronicity between the pipes on both sides during chamfering and welding.

[0015] 2. Utilizing a tooth meshing mechanism, the rotating rack and rotating gear mesh together. When the ratchet is not engaged with the rotating ratchet, the friction between the rubber strip and the rotating ring causes the rotating gear to drive the rotating ratchet to rotate, changing the orientation of the welding machine and the chamfering knife. When the ratchet is engaged with the rotating ratchet, the rotating ratchet does not drive the rotating ring and the flipping plate to flip, and does not change the orientation of the welding machine and the chamfering knife, thus meeting the requirements for chamfering and welding.

[0016] 3. The high-pressure airflow drives the chamfering impeller to rotate, which in turn drives the chamfering blade to rotate, chamfering the welding position of the pipe. The high-pressure airflow is discharged through the exhaust pipe, blowing off the waste generated during chamfering and cooling the chamfering blade. It can also remove the burrs generated at the welding position after welding is completed, and the high-pressure airflow cools the welding position during the removal process.

[0017] 4. High-pressure airflow is used to drive the transmission impeller and the drive gear to rotate. Through the transmission between the drive gear and the driven gear, the fixed gear column is driven to rotate. At the same time, the pneumatic telescopic rod is activated, which moves the support frame through the moving plate and the push plate, and moves the pipes on both sides and the drive gear ring. During the movement, the fixed gear column meshes with the drive gear ring, and the drive gear ring is driven to rotate. During the rotation, the drive shell drives the drive rod and the fixed claw to fix the pipes coaxially through the planar thread. After the pipes are fixed, the pipes on both sides rotate synchronously and move to the appropriate position, so that the gap between the pipes on both sides can be adjusted according to different welding requirements.

[0034] like Figure 1 and Figures 5-7 As shown, the pneumatic transmission assembly 7 includes a transmission housing 701, a transmission impeller 702, a transmission drive gear 703, a support rod 704, a fixed gear 705, a driven driven gear 706, and a transmission shaft 707. The side wall of the transmission housing 701 is fixedly connected to the side wall of the lifting bracket 401. The transmission housing 701 is hollow. The input end of the transmission housing 701 is connected to the output end of the air pump 8 through an air pipe. The side wall of the transmission impeller 702 is rotatably connected to the inner side wall of the transmission housing 701. The side wall of the transmission drive gear 703 is connected to the transmission housing 701. 01 The sidewall is rotatably connected, and the sidewall of the drive gear 703 is coaxially and fixedly connected to the sidewall of the drive impeller 702. The support rod 704 is symmetrically and fixedly connected to both sides of the top wall of the base 1. The drive shaft 707 is rotatably connected to the support rod 704 on both sides. The two ends of the drive shaft 707 are coaxially and fixedly connected to the fixed gear column 705. The outer edge of one side of the fixed gear column 705 is set with an inclined side. The driven gear 706 is fixedly connected to the drive shaft 707. The driven gear 706 is meshed with the drive gear 703.

[0035] like Figure 1 and Figures 7-10 As shown, the pipe fixing assembly 3 includes a support frame 301 symmetrically fixedly connected to the top wall of the push plate 204. A drive shell 304 is rotatably connected to the side wall of the support frame 301. The drive shell 304 is hollow and annular. Drive toothed rings 303 are fixedly connected to the outer circumferential walls of the drive shell 304 on both sides. One outer edge of the drive toothed ring 303 is inclined. The drive toothed ring 303 meshes with the fixed toothed column 705 during movement. The pipe fixing assembly 3 also includes a planar thread 308 fixedly connected to the inner side wall of the drive shell 304. A drive rod 306 is slidably connected to one side wall of the drive shell 304 in an annular array. The side wall of the drive rod 306 is movably engaged with the planar thread 308. The planar thread 308 pushes the drive rod 306 to move towards the axial position of the drive shell 304. A fixing claw 307 is fixedly connected to the other side wall of the drive rod 306. The other end of the fixing claw 307 is arc-shaped.

[0036] like Figures 1-2 and Figures 4-5 As shown, the pneumatic chamfering assembly 6 includes a tool housing 601, a chamfering impeller 602, a rotating ring 603, an air outlet pipe 604, and a chamfering blade 605. The side wall of the tool housing 601 is fixedly connected to the side wall of the flip plate 512. The tool housing 601 is hollow. The rotating ring 603 is rotatably connected to one side of the circumferential wall of the tool housing 601. The other end of the rotating ring 603 is connected to the output end of the air pump 8 through an air pipe. The air outlet pipe 604 is fixedly connected to the other side of the circumferential wall of the tool housing 601. The chamfering impeller 602 is rotatably connected to the inner bottom wall of the tool housing 601. The chamfering blade 605 is rotatably connected to the bottom wall of the tool housing 601. One end of the chamfering blade 605 is tapered, and the other end of the chamfering blade 605 is coaxially and fixedly connected to the chamfering impeller 602.

[0037] Place the device in a suitable position, insert the pipe into the hollow space on the support frame 301 and the drive housing 304, then start the air pump 8. The high-pressure airflow enters the drive housing 701, driving the drive impeller 702 to rotate. The drive impeller 702 drives the drive gear 703 to rotate, which in turn drives the driven gear 706 to rotate, causing the drive shaft 704 to rotate on the support rod 704, which in turn drives the fixed gear 705 to rotate. Simultaneously, the pneumatic telescopic rod 202 is activated, moving the moving plate 203 and the push plate 204. The push plate 204 moves the support frame 301, moving both sides... As the pipe approaches, the support frame 301 pushes the drive housing 304 to move, which in turn pushes the gear ring 303 to move. During this movement, one inclined side of the gear ring 303 gradually approaches the side of the fixed gear post 705, causing the gear ring 303 to mesh with the fixed gear post 705. The fixed gear post 705 then drives the gear ring 303 to rotate, which in turn drives the drive housing 304 to rotate. The drive housing 304 then drives the planar thread 308 to rotate, which in turn pushes the drive rod 306 and the fixing claw 307 to move centripetally. The arc-shaped end of the fixing claw 307 coaxially fixes the pipe. After the pipe is fixed, the drive ring 303... The drive housing 304 continues to rotate, driving the pipes to rotate via the drive rod 306 and the fixed claw 307. At this time, the pipes on both sides are coaxially fixed and rotate at a uniform speed. The pipes on both sides gradually move closer together. The lifting pneumatic telescopic rod 402 is activated, driving the lifting plate 403 to move away from the lifting bracket 401, driving the connecting frame 501 to move, and driving the rotating gear 503 to move. The rotating gear 503 meshes with the rotating rack 502. The rotating gear 503 drives the guide groove 509 and the rubber strip 510 to rotate. The ratchet 506 does not jam the rotating ratchet 504. The ratchet 506 drives the connecting rod 505 to swing on the connecting frame 501. The connecting rod 505 and the connecting... The frame 501 compresses the connecting spring 507. The rotating ratchet 504 drives the rotating ring 511 to not rotate with the rubber strip 510. The friction between the rubber strip 510 and the rotating ring 511 drives the rotating ratchet 504 to rotate, which in turn drives the rotating gear 503 to rotate the rotating ratchet 504. The rotating ratchet 504 drives the rotating plate 508 to rotate, and the rotating plate 508 drives the flipping plate 512 to rotate. The welding machine 9 faces the pipes on both sides. When the welding machine 9 approaches the pipes on both sides, the lifting pneumatic telescopic rod 402 stops, which makes it easy to adjust the weld distance according to the welding requirements. When the gap between the pipes on both sides moves to the welding requirements, the moving pneumatic telescopic rod 202 stops.

[0038] Example 2 is based on the previous example, but with chamfering and welding.

[0039] Specifically, when the lifting pneumatic telescopic rod 402 is activated, it moves the lifting plate 403 away from the lifting bracket 401, causing the connecting frame 501 to move, which in turn moves the rotating gear 503. The rotating gear 503 meshes with the rotating rack 502, causing the guide groove 509 and the rubber strip 510 to rotate. The ratchet 506 does not jam the rotating ratchet 504, and the ratchet 506 causes the connecting rod 505 to swing on the connecting frame 501. The connecting rod 505 and the connecting frame 501 compress the connecting spring 507, and the rotating ratchet 504 causes the rotating ring 511 to not... The rubber strip 510 rotates, and the friction between the rubber strip 510 and the rotating ring 511 drives the rotating ratchet 504 to rotate. This, in turn, drives the rotating gear 503 to rotate the rotating ratchet 504, which in turn drives the rotating plate 508 to rotate. The rotating plate 508 then drives the tilting plate 512 to rotate. The chamfering cutter 605 faces the pipes on both sides. The air pump inputs high-pressure airflow into the cutter housing 601, driving the chamfering impeller 602 to rotate, which in turn drives the chamfering cutter 605 to rotate. The chamfering cutter 605 moves closer to the pipes on both sides. When it reaches the appropriate chamfering depth, it rises and falls. When the pneumatic telescopic rod 402 stops, the welding positions of the pipes on both sides continue to rotate, chamfering is performed. Simultaneously, the high-pressure airflow inside the tool housing 601 is discharged through the air outlet 604, blowing away the waste generated during chamfering. After chamfering is completed, the lifting pneumatic telescopic rod 402 starts, moving the lifting plate 403 closer to the lifting bracket 401. The air pump stops, inputting high-pressure airflow into the tool housing 601. The rotating gear 503 meshes with the rotating rack 502, and the rotating gear 503 rotates in the opposite direction, driving the guide groove 509. As the rubber strip 510 rotates, the ratchet 506 engages the rotating ratchet 504. The ratchet 506 does not drive the connecting rod 505 to swing on the support frame 301. The connecting spring 507 pulls the ratchet 506 and the connecting rod 505, further engaging the rotating ratchet 504. The rotating ratchet 504 drives the rotating ring 511 and the rubber strip 510 to rotate. The rotating gear 503 does not drive the rotating ratchet 504 to rotate. The rotating ratchet 504 does not drive the rotating plate 508 to rotate. The rotating plate 508 does not drive the flipping plate 512 to rotate. The chamfering cutter 605 faces the pipes on both sides.

[0040] When the pneumatic telescopic rod 402 is activated, it moves the lifting plate 403 away from the lifting bracket 401, causing the connecting frame 501 to move, which in turn moves the rotating gear 503. The rotating gear 503 meshes with the rotating rack 502, causing the guide groove 509 and rubber strip 510 to rotate. This, in turn, causes the rotating gear 503 to rotate the rotating ratchet 504. The ratchet 506 does not engage the rotating ratchet 504, causing the connecting rod 505 to swing on the connecting frame 501. The connecting rod 505 and the connecting frame 501 compress the connecting spring 507. The rotating ratchet 504 causes the rotating ring 511 to not rotate with the rubber strip 510. Friction between the rubber strip 510 and the rotating ring 511 causes the rotating ratchet 504 to rotate, which in turn causes the rotating gear 503 to rotate the rotating ratchet 504. 4. Rotation: The rotating ratchet 504 drives the rotating plate 508 to rotate, and the rotating plate 508 drives the flipping plate 512 to rotate. The welding machine 9 faces the pipes on both sides. When it moves to the appropriate position, the lifting pneumatic telescopic rod 402 stops, and the welding machine 9 starts. As the pipes on both sides continue to rotate, the welding position of the pipes on both sides after chamfering is welded. After welding is completed, the lifting pneumatic telescopic rod 402 starts, driving the lifting plate 403 to move closer to the lifting bracket 401. The rotating gear 503 does not drive the rotating ratchet 504 to rotate, the rotating ratchet 504 does not drive the rotating plate 508 to rotate, and the rotating plate 508 does not drive the flipping plate 512 to rotate. The welding machine 9 faces the pipes on both sides, and the lifting pneumatic telescopic rod 402 stops. After welding is completed, the pipes on both sides continue to rotate to cool the welded position of the pipes.

[0041] When the pneumatic telescopic rod 402 is activated, it moves the lifting plate 403 away from the lifting bracket 401, causing the connecting frame 501 to move, which in turn moves the rotating gear 503. The rotating gear 503 meshes with the rotating rack 502, causing the guide groove 509 and the rubber strip 510 to rotate. This, in turn, causes the rotating gear 503 to rotate the rotating ratchet 504. The ratchet 506 does not engage the rotating ratchet 504, causing the connecting rod 505 to swing on the connecting frame 501. The connecting rod 505 and the connecting frame 501 compress the connecting spring 507. The rotating ratchet 504 causes the rotating ring 511 to not rotate with the rubber strip 510. Friction between the rubber strip 510 and the rotating ring 511 causes the rotating ratchet 504 to rotate, which in turn causes the rotating gear 503 to rotate the rotating ratchet 504. The rotating ratchet 504 then rotates the rotating plate 508, which in turn rotates the tilting plate 512. The welding machine 9 then moves towards the pipes on both sides. When the tool reaches the appropriate position, the lifting pneumatic telescopic rod 402 stops, and the air pump inputs high-pressure airflow into the tool housing 601, driving the chamfering impeller 602 to rotate, which in turn drives the chamfering blade 605 to rotate. The chamfering blade 605 moves closer to the pipes on both sides. When it reaches the appropriate chamfering depth, the lifting pneumatic telescopic rod 402 stops. As the pipes on both sides continue to rotate, the burrs at the welded position are removed. At the same time, the high-pressure airflow in the tool housing 601 is discharged from the tool housing 601 through the air outlet pipe 604, blowing off the waste chips generated during burr removal and further reducing the temperature. After the burrs are removed, the lifting pneumatic telescopic rod 402 starts, driving the lifting plate 403 to move closer to the lifting bracket 401. The air pump stops inputting high-pressure airflow into the tool housing 601. The rotating gear 503 does not drive the rotating ratchet 504 to rotate, the rotating ratchet 504 does not drive the rotating plate 508 to rotate, and the rotating plate 508 does not drive the flipping plate 512 to rotate. The chamfering blade 605 faces the pipes on both sides.

[0042] Example 3, based on the previous example, involves loosening the pipe.

[0043] Specifically, the air pump 8 draws air from the transmission housing 701, and the external air enters the transmission housing 701, causing the transmission impeller 702 to rotate in the opposite direction. The transmission impeller 702 drives the transmission drive gear 703 to rotate in the opposite direction, which in turn drives the driven gear 706 to rotate in the opposite direction. The driven gear drives the transmission shaft 704 to rotate in the opposite direction on the support rod 704. The transmission shaft 707 drives the fixed gear column 705 to rotate in the opposite direction, which in turn drives the gear ring 303 to rotate in the opposite direction, causing the transmission housing 304 to rotate in the opposite direction. The transmission housing 304 then drives the planar thread 308 to rotate in the opposite direction, and the planar thread 308 pushes the drive rod 3... 06 and the fixed claw 307 move centrifugally, the fixed claw 307 loosens the pipe, the air pump 8 stops drawing air from the transmission housing 701, then the pneumatic telescopic rod 202 starts, the pneumatic telescopic rod 202 drives the moving plate 203 and the pushing plate 204 to move, the pushing plate 204 drives the support frame 301 to move away from the welding position of the pipes on both sides, the support frame 301 pushes the housing 304 and the connecting cylinder 302 to move, the connecting cylinder 302 pushes the toothed ring 303 to move, causing the toothed ring 303 to disengage from the fixed toothed column 705, then the pneumatic telescopic rod stops, thus achieving the function of loosening and holding the pipe after welding.
