Description

Technical Field

[0001] The present application relates to the field of welding equipment, and in particular to a ring beam submerged arc welding machine and a single pile cage manufacturing method. Background Art

[0002] The monopile cage is the supporting foundation of offshore wind power equipment. The monopile cage is generally composed of a ladder, a working platform, a ring beam, a support pipe and a crash bar. The ring beam is formed by welding two upper and lower cover rings and two inner and outer support rings. The welding of the ring beam generally uses a submerged arc welding machine. At present, the relevant technology discloses a submerged arc welding machine, including a vehicle body, a support column is rotatably plugged into the top side of the vehicle body, and a lifting ring is provided on the threaded sleeve of the support column. The lifting ring is fixedly installed with a mounting frame, and the mounting frame is fixedly installed with a wire feeder, a storage hopper, a wire reel and a controller. The bottom side of the wire feeder is fixedly installed with a welding head, and the side wall of the welding head is fixedly installed with a feed pipe. A hose is connected between the storage hopper and the feed pipe. The controller is used to open and close the wire feeder, the welding head and the vehicle body. The wire reel is used to place welding wire, and the inside of the storage hopper is used to place flux.

[0003] After the cover ring and the support ring are spliced ​​to form a ring beam, the vehicle body is placed on the cover ring on the top side. Then the lifting ring is turned to lift and lower, thereby adjusting the distance between the welding head and the cover ring. Then the support column is turned so that the welding head faces the connection between the cover ring and the support ring. The controller starts the vehicle body to move on the cover ring, and the vehicle body drives the welding head to move, and the welding head moves along the connection between the cover ring and the support ring. When the welding head moves along the connection between the cover ring and the support ring, the controller starts the wire feeder and the welding head, and the wire feeder pulls the welding wire into the welding head. The flux enters the welding head from the hose and the feed pipe and falls into the connection between the cover ring and the support ring. The welding head electrically heats the welding wire and the flux, thereby melting the welding wire and the flux. After the welding wire and the flux cool and solidify, the cover ring and the support ring will be connected together.

[0004] In the above-mentioned related technologies, the ring beam is circular, and the connection between the cover ring and the support ring is also circular, so the welding head needs to align with the connection between the cover ring and the support ring to make a circular motion, and then the car body needs to make a circular motion on the top side of the ring beam. In order to make the car body make a circular motion on the ring beam, the staff needs to repeatedly adjust the direction of the car body, which increases the difficulty of welding. Summary of the invention

[0005] In order to facilitate the welding of ring beams, the present application provides a ring beam submerged arc welding machine and a single pile cage manufacturing method.

[0006] The present application provides a ring beam submerged arc welding machine and a single pile cage manufacturing method, which adopts the following technical solutions: A ring beam submerged arc welding machine comprises a car body, a support column is rotatably inserted on the top side of the car body, the support column threaded sleeve is provided with a lifting ring, the lifting ring is fixedly installed with a mounting frame, and a wire feeder, a storage hopper, a welding wire reel and a controller are fixedly installed on the mounting frame, a welding head is fixedly installed on the bottom side of the wire feeder, a feeding pipe is fixedly installed on the side wall of the welding head, a hose is connected between the storage hopper and the feeding pipe, and the controller is used to open and close the wire feeder, the welding head and the car body, and mounting plates are fixedly installed on the front and rear sides of the moving direction of the car body, sliding rods are provided at both ends of the mounting plate, and the mounting plate is provided with a sliding opening for the sliding rod to slide through, the sliding rod threaded sleeve is provided with a first limiting ring and a second limiting ring, and a guide wheel is rotatably installed on the bottom end of the slide rod, and the guide wheel is used to roll against the side wall of the ring beam.

[0007] By adopting the above technical solution, when the submerged arc welding machine is placed on the top side of the ring beam, the slide bar is moved so that the guide wheel at one end of the mounting plate abuts against the outer wall of the ring beam, and the guide wheel at the other end of the mounting plate abuts against the inner wall of the ring beam. Then the controller starts the movement of the vehicle body, and guides the guide wheels on both sides of the ring beam, so that the vehicle body can move in a circle on the top side of the ring beam, and then the welding head can move along the connection between the cover ring and the support ring, so that the welding head can weld the connection between the cover ring and the support ring.

[0008] Optionally, a filter screen is installed inside the storage hopper, a vacuum cleaner is installed on the top side of the storage hopper, and the vacuum cleaner is connected to a dust suction pipe.

[0009] By adopting the above technical solution, when the soldering solder falls from the soldering head into the connection between the cover ring and the support ring, the soldering head generally melts part of the soldering solder, and the other part remains in granular form. The position of the dust suction pipe is adjusted to allow the dust suction pipe to absorb the unmelted soldering solder. After that, the soldering solder falls into the filter screen, and after the filter screen filters the impurities, the soldering solder returns to the inside of the storage hopper, thereby facilitating the recovery of the soldering solder.

[0010] Optionally, the welding head rotating sleeve is provided with a first mounting ring, the first mounting ring is provided with a screw, the screw passes through the first mounting ring along the radial thread of the first mounting ring, the circumferential side of the welding head is provided with a ring groove for the screw to pass through, the outer wall of the first mounting ring is fixedly installed with a telescopic rod, the end of the telescopic rod away from the welding head is fixedly installed with a second mounting ring, and the second mounting ring is fixedly sleeved on the dust suction pipe.

[0011] By adopting the above technical solution, the length of the telescopic rod is adjusted and the first mounting ring is rotated so that the dust suction tube is directed toward the connection between the cover ring and the support ring, thereby facilitating the fixing of the dust suction tube and allowing the dust suction tube to absorb unmelted solder.

[0012] Optionally, the vehicle body is provided with a first connecting rod, and a first slot for damping and plugging one end of the first connecting rod is opened on both sides of the vehicle body, a second connecting rod is hingedly connected to the end of the first connecting rod away from the vehicle body, a locking assembly is installed between the first connecting rod and the second connecting rod, and the locking assembly is used to limit the rotation of the second connecting rod, and a material receiving mechanism is fixedly installed on the end of the second connecting rod away from the first connecting rod, and the material receiving mechanism is used to recover the solder that falls on the ring beam.

[0013] By adopting the above technical solution, when the solder falls from the welding head into the connection between the cover ring and the support ring, part of the solder will fall from the edge of the top side of the ring beam. Insert the first connecting rod into the first slot, and then rotate the second connecting rod to allow the material receiving mechanism to abut against the side plate of the ring beam. After the material receiving structure abuts against the side wall of the ring beam, the locking assembly is locked to limit the rotation of the second connecting rod. After that, the solder falling from the edge of the ring beam will fall into the material receiving mechanism, thereby facilitating the recovery of the solder.

[0014] Optionally, the locking assembly includes a locking rod, a first locking ring and a second locking ring, one end of the locking rod is hinged to the rod body of the first connecting rod, the other end of the locking rod is hinged to the first locking ring, the first locking ring is slidably sleeved on the second connecting rod, the second locking ring is threadedly sleeved on the second connecting rod, and the second locking ring is located on the side of the first locking ring close to the first connecting rod.

[0015] By adopting the above technical solution, when it is necessary to move the material receiving mechanism to abut against the side wall of the ring beam, the second locking ring is rotated to move the second locking ring away from the first locking ring. Then, the second connecting rod is rotated toward the side wall of the ring beam. When the material receiving mechanism abuts against the side wall of the ring beam, the second connecting rod cannot continue to rotate toward the side wall of the ring beam. Then, the second locking ring is rotated to abut against the first locking ring, thereby limiting the rotation of the second connecting rod away from the ring beam, thereby facilitating the material receiving mechanism to remain abutted against the side wall of the ring beam.

[0016] Optionally, the material receiving mechanism includes a third connecting rod, a sliding sleeve, a latch, a side plate and a bottom plate, one end of the third connecting rod is fixedly connected to an end of the second connecting rod away from the first connecting rod, the third connecting rod is rectangular, the sliding sleeve is slidingly sleeved on the third connecting rod, the latch is plugged into the third connecting rod, there are two latches and they are respectively pressed against the two ends of the sliding sleeve, the outer wall of the sliding sleeve is fixedly connected to the side plate, the bottom side of the side plate is fixedly connected to one side of the bottom plate, and the side of the bottom plate away from the side plate is used to fit the side wall of the ring beam.

[0017] By adopting the above technical solution, the third connecting rod is passed through the sliding sleeve, and then the sliding sleeve is limited by a pin passing through the third connecting rod, so that the sliding sleeve remains fixed. After the second connecting rod is rotated, the bottom plate is abutted against the side plate of the ring beam. The solder flux that falls from the top edge of the ring beam will then fall into the bottom plate, and the solder flux will gather in the space enclosed by the bottom plate, the side plate, and the side wall of the ring beam. When the accumulated amount of solder flux is about to fall from both ends of the bottom plate, the vacuum tube is moved to absorb the solder flux on the bottom plate, thereby facilitating the recovery of the solder flux.

[0018] Optionally, the base plate is provided with an installation opening, and a plurality of extension rods are telescopically arranged inside the installation opening, and the plurality of extension rods are closely arranged inside the installation opening, a pressure rod is provided on the bottom side of the base plate, and a pressure plate is fixedly installed on the rod body of the pressure rod, and mounting seats and bolts are provided at both ends of the pressure rod, and the mounting seats are fixedly installed on the bottom surface of the base plate, and the bolts slide through the pressure rod, and the bolt threads are penetrated through the bottom side of the mounting seat, and a first avoidance opening for the pressure plate to enter is provided on the bottom surface of the base plate, and the first avoidance opening is connected to the installation opening, and the pressure plate presses each of the extension rods after entering from the first avoidance opening.

[0019] By adopting the above technical solution, each extension rod is extended from the installation opening and abuts against the side wall of the ring beam. After that, the bolt passes through the pressure rod and is screwed into the mounting seat. After the pressure plate enters the first avoidance opening, each extension rod is pressed tightly, so that the extension rod is conveniently kept fixed inside the installation opening. Ring beams of different diameters have different curvatures of the side walls of the ring beam. By extending and retracting the extension rod and abutting against the side wall of the ring beam, the material receiving mechanism is conveniently applicable to ring beams of different diameters.

[0020] Optionally, a mounting block is provided at one end of the extension rod facing the ring beam, and a first plug rod is fixedly installed on the side of the mounting block close to the extension rod, and a second slot for the first plug rod to be plugged into is opened at one end of the extension rod close to the mounting block, and a sphere is interference-mounted on the end of the mounting block away from the extension rod, and the sphere is used to abut against the side wall of the ring beam, and the first plug rod is wrapped with an elastic sleeve, a gap is left between the mounting block and the extension rod, and a gap is also left between two adjacent mounting blocks, and a second plug rod is fixedly installed on the top side of the mounting block, and a first blocking piece is provided on the bottom plate, and the first blocking piece is opened with a socket for the second plug rod to be plugged in, and a second blocking piece is fixedly installed on the side of the first blocking piece close to the ring beam, and the second blocking piece is inclined, and the first blocking piece and the second blocking piece are both elastic, and the second blocking piece abuts against the side wall of the ring beam.

[0021] By adopting the above technical solution, when the vehicle body makes a circular motion on the ring beam, the material receiving mechanism will also make a circular motion against the side wall of the ring beam. The sliding friction is converted into rolling friction by the sphere, thereby reducing the resistance to the movement of the vehicle body. At the same time, there is a certain error in the production of the ring beam, so that the actual shape of the ring beam is an ellipse. By leaving a gap between the mounting block and the extension rod, and a gap between two adjacent mounting blocks, when the sphere is squeezed against the side wall of the ring beam, the mounting block will move, thereby reducing the situation where the side wall of the ring beam and the sphere are stuck to each other and cannot move.

[0022] Optionally, baffles are provided at both ends of the base plate, a first sliding groove is provided on the top surface of the base plate for the baffle to slide through, and a second avoidance opening is provided on the side plate for avoiding the baffle. The base plate is gradually lowered and inclined from one end close to the first connecting rod to the other end.

[0023] By adopting the above technical solution, the baffle is pushed against the side wall of the ring beam. After the soldering material falls into the bottom plate, the soldering material moves toward the baffle due to the inclination of the bottom plate. The baffle blocks the soldering material, thereby reducing the soldering material from falling from the end of the bottom plate away from the first connecting rod, thereby facilitating the recovery of the soldering material.

[0024] A method for manufacturing a single pile cage, using a ring beam submerged arc welding machine of the present application, comprises the following steps: Cutting and bending the steel to form a cover ring and a support ring, wherein the two cover rings are on the upper and lower sides, and the two support rings are spliced ​​together on the inner and outer sides, and then welded using a submerged arc welding machine to form a ring beam; Cut pipes to form anti-collision pipes and support pipes, and then make working platforms and ladders; The ring beam, anti-collision pipe, support pipe, working platform and ladder are spliced ​​and welded to form a single pile cage.

[0025] By adopting the above technical solution, the submerged arc welding machine of the present application does not require the staff to repeatedly adjust the moving direction when moving on the ring beam for welding, thereby reducing the difficulty of welding.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The guide wheel at one end of the mounting plate rolls against the outer wall of the ring beam, and the guide wheel at the other end of the mounting plate rolls against the inner wall of the ring beam. The guide wheel guides the vehicle body so that it automatically turns to move in a circular motion when it moves on the top side of the ring beam, thereby facilitating the welding head to move along the connection between the cover ring and the support ring, and facilitating the welding head to weld the connection between the cover ring and the support ring; 2. The material receiving mechanism is pressed against the side wall of the ring beam. When the soldering material falls from the edge of the top side of the ring beam, the material receiving mechanism catches the soldering material, thereby facilitating the recovery of the soldering material.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] Example 1.

[0031] The embodiments of the present application disclose a ring beam submerged arc welding machine and a method for manufacturing a single pile cage.

[0032] Reference Figure 1 , Figure 2 A ring beam submerged arc welding machine comprises a car body 1, a support column 2 is rotatably inserted on the top side of the car body 1, the support column 2 can rotate, but the support column 2 cannot be pulled out of the car body 1. A limit rod 3 is threadedly inserted on the side wall of the car body 1, and the rotation limit rod 3 is tightly pressed against the peripheral side of the support column 2, thereby limiting the rotation of the support column 2. The rotation limit rod 3 is away from the support column 2, so that the support column 2 is convenient to rotate.

[0033] The support column 2 is threadedly sleeved with a lifting ring 4. By rotating the lifting ring 4 through the thread between the lifting ring 4 and the support column 2, the lifting ring 4 can be raised and lowered on the support column 2.

[0034] The lifting ring 4 is fixedly mounted with a mounting frame 5, which is located at the front side of the vehicle body 1 in the direction of travel and is fixedly mounted with a welding wire reel 6 and a controller 7, and the mounting frame 5 is located at the rear side of the vehicle body 1 in the direction of travel and is fixedly mounted with a wire feeder 8 and a storage hopper 9. A welding head 10 is fixedly mounted on the bottom side of the wire feeder 8, and a feed pipe 11 is fixedly mounted on the side wall of the welding head 10. A hose 12 is fixedly connected between the storage hopper 9 and the feed pipe 11, The controller 7 is used to open and close the wire feeder 8, the welding head 10 and the vehicle body 1. The welding wire reel 6 is used to place the welding wire, and the storage hopper 9 is used to place the soldering flux. The wire feeder 8 pulls the welding wire from the welding wire reel 6 and feeds it into the welding head 10. The soldering flux enters the welding head 10 from the hose 12 and the feed pipe 11. After the welding wire and the soldering flux are drawn out from the welding head 10, the welding head 10 heats the welding wire and the soldering flux, thereby melting the welding wire and the soldering flux.

[0035] Reference Figure 1 , Figure 2 The front and rear sides of the vehicle body 1 in the direction of travel are fixedly mounted with mounting plates 13, and both ends of the mounting plates 13 are provided with slide bars 14. The mounting plates 13 are provided with a sliding opening 15 for the slide bars 14 to slide through, and the slide bars 14 are threadedly sleeved with a first limiting ring 16 and a second limiting ring 17. The bottom end of the slide bars 14 is rotatably mounted with a guide wheel 18, and the guide wheel 18 is used to roll against the side wall of the ring beam 19.

[0036] Reference Figure 3 A method for manufacturing a single pile cage, using a ring beam submerged arc welding machine according to an embodiment of the present application, comprises the following steps: The steel is cut and bent to form a cover ring 191 and a support ring 192. The two cover rings 191 are on the upper and lower sides, and the two support rings 192 are spliced ​​together on the inner and outer sides, and then welded using a submerged arc welding machine to form a ring beam 19; Cut the pipe to form the anti-collision pipe 20 and the support pipe 21, and then make the working platform 22 and the ladder 23; The ring beam 19, the anti-collision pipe 20, the support pipe 21, the working platform 22 and the ladder 23 are spliced ​​and welded to form a single pile cage.

[0037] The implementation principle of a submerged arc welding machine for a ring beam and a method for manufacturing a single pile cage in an embodiment of the present application is as follows: two support rings 192 are placed concentrically in a circle, and then a cover ring 191 is placed in a circle above and below the two support rings 192, and then the cover ring 191 and the support ring 192 are welded to form a ring beam 19.

[0038] When the cover ring 191 and the support ring 192 need to be welded, the vehicle body 1 is placed on the top side of the ring beam 19, and the slide bar 14 is pushed to slide inside the slide opening 15, so that the guide wheel 18 at one end of the mounting plate 13 abuts against the inner wall of the ring beam 19, and the guide wheel 18 at the other end of the mounting plate 13 abuts against the outer wall of the ring beam 19, and then the first limit ring 16 and the second limit ring are tightened, so that the slide bar 14 remains fixed inside the slide opening 15. The guide wheel 18 abuts against the inner and outer walls of the ring beam 19 for guidance, so that the vehicle body 1 can automatically adjust the direction to match the shape of the ring beam 19 and perform circular motion, thereby facilitating the welding of the ring beam 19.

[0039] Then, the lifting ring 4 is rotated, and the lifting ring 4 drives the entire mounting frame 5 to rise and fall, so as to facilitate the adjustment of the distance between the welding head 10 and the top side of the ring beam 19. After adjusting the distance between the welding head 10 and the top side of the ring beam 19, the support column 2 is rotated to make the welding head 10 face the connection between the cover ring 191 and the support ring 192. After the welding head 10 faces the connection between the cover ring 191 and the support ring 192, the limit rod 3 is rotated to make the limit rod 3 close to the support column 2, thereby limiting the rotation of the support column 2, and then facilitating the welding head 10 to face the connection between the cover ring 191 and the support ring 192.

[0040] Then the controller 7 starts the vehicle body 1 to move. The vehicle body 1 is restricted by the guide wheel 18 against the inner and outer sides of the ring beam 19. The vehicle body 1 moves in a circle on the top side of the ring beam 19, and the vehicle body 1 drives the welding head 10 to move along the connection between the cover ring 191 and the support ring 192. At the same time, the controller 7 starts the welding head 10 and the wire feeder 8. The wire feeder 8 pulls the welding wire from the welding wire reel 6 into the welding head 10, and the flux enters the welding head 10 from the storage hopper 9. Then the flux falls from the welding head 10 into the connection between the cover ring 191 and the support ring 192. Then the welding head 10 heats the welding wire and the flux, and the welding wire and the flux are melted to cover the connection between the support ring 192 and the cover ring 191. After the welding wire and the flux are cooled and solidified, the cover ring 191 and the support ring 192 are fixedly connected to each other.

[0041] Example 2.

[0042] The embodiments of the present application disclose a ring beam submerged arc welding machine and a method for manufacturing a single pile cage.

[0043] Reference Figure 4 , Figure 5 The difference between the ring beam submerged arc welding machine of the embodiment of the present application and the embodiment 1 is that a filter screen plate 24 is provided inside the storage hopper 9, and a slider 25 is fixedly installed around the filter screen plate 24. The inner wall of the storage hopper 9 is provided with a second slide groove 57 for the slider 25 to slide up and down. The slider 25 slides into the second slide groove 57, so that the filter screen plate 24 is conveniently installed inside the storage hopper 9. The filter screen plate 24 filters the solder placed in the storage hopper 9, thereby reducing the occurrence of impurities being discharged from the storage hopper 9 to the welding head 10.

[0044] A vacuum cleaner 27 is provided on the top side of the storage hopper 9. An elastic clip 28 is fixedly installed on the bottom side of the vacuum cleaner 27. The elastic clip 28 is used to clamp the top side of the storage hopper 9, so that the vacuum cleaner 27 is installed on the top side of the storage hopper 9. The vacuum cleaner 27 is connected to a vacuum pipe 29. When the soldering material is melted at the connection between the cover ring 191 and the support ring 192 for welding, there will generally be some excess solder that is not melted. Let the vacuum pipe 29 face the excess solder, and then start the vacuum cleaner 27, so that the excess solder on the top side of the ring beam 19 returns to the inside of the storage hopper 9, thereby facilitating the recovery of the excess solder on the top side of the ring beam 19.

[0045] Reference Figure 4 , Figure 5 The welding head 10 is rotatably sleeved with a first mounting ring 30, and the first mounting ring 30 is provided with a screw 32, and the screw 32 penetrates the first mounting ring 30 along the radial thread of the first mounting ring 30. A ring groove 33 for the screw 32 to penetrate is provided on the peripheral side of the welding head 10, and a telescopic rod 34 is fixedly installed on the outer wall of the first mounting ring 30. A second mounting ring 31 is fixedly installed on one end of the telescopic rod 34 away from the welding head 10, and the second mounting ring 31 is fixedly sleeved on the dust suction pipe 29.

[0046] Adjust the length of the telescopic rod 34 and rotate the first mounting ring 30 to move the dust suction tube 29 to the connection between the cover ring 191 and the support ring 192 where the soldering material has cooled and solidified. Then tighten the screw 32, which is tightly against the inner bottom wall of the annular groove 33, so as to facilitate the fixing of the dust suction tube 29. When the vehicle body 1 makes a circular motion on the top side of the ring beam 19, the dust suction tube 29 moves with the vehicle body 1 and remains facing the top of the soldering material that has cooled and solidified, so as to facilitate the vacuum cleaner 27 to recover the excess soldering material through the dust suction tube 29.

[0047] Reference Figure 6 , Figure 7 The vehicle body 1 is provided with a first connecting rod 35, and both sides of the vehicle body 1 are provided with a first slot 37 for damping insertion of one end of the first connecting rod 35. When welding the connection between the outer support ring 192 and the cover ring 191, the first connecting rod 35 is inserted into the first slot 37 on the outer side of the vehicle body 1; when welding the connection between the inner support ring 192 and the cover ring 191, the first connecting rod 35 is inserted into the first slot 37 on the inner side of the vehicle body 1.

[0048] The first connecting rod 35 and the first slot 37 are both square, thereby limiting the rotation of the first connecting rod 35. The first connecting rod 35 is hinged to one end away from the vehicle body 1 with the second connecting rod 36. The second connecting rod 36 is rotated so that the second connecting rod 36 is close to or away from the side wall of the ring beam 19.

[0049] Reference Figure 6 , Figure 7 A locking assembly 38 is installed between the first connecting rod 35 and the second connecting rod 36, and the locking assembly 38 includes a locking rod 381, a first locking ring 382, ​​and a second locking ring 383. One end of the locking rod 381 is hinged to the rod body of the first connecting rod 35, and the other end of the locking rod 381 is hinged to the first locking ring 382. The first locking ring 382 is slidably sleeved on the second connecting rod 36, and the second locking ring 383 is threadedly sleeved on the second connecting rod 36. The second locking ring 383 is located on the side of the first locking ring 382 close to the first connecting rod 35.

[0050] When the second connecting rod 36 needs to be rotated, the second locking ring 383 is rotated away from the first locking ring 382, ​​so as to facilitate the first locking ring 382 to slide away from the first connecting rod 35, thereby facilitating the second connecting rod 36 to rotate away from the side wall of the ring beam 19. After the second connecting rod 36 is rotated, the second locking ring 383 is rotated to abut against the first locking ring 382, ​​thereby limiting the first locking ring 382 from moving away from the first connecting rod 35, thereby limiting the second connecting ring from rotating away from the side wall of the ring beam 19.

[0051] Reference Figure 6 , Figure 7The second connecting rod 36 is provided with a material receiving mechanism 39, which includes a third connecting rod 391, a sliding sleeve 392, a latch 393, a side plate 394 and a bottom plate 395. One end of the third connecting rod 391 is fixedly connected to an end of the second connecting rod 36 away from the first connecting rod 35. The sliding sleeve 392 is slidingly sleeved on the third connecting rod 391, and the third connecting rod 391 is rectangular, so that the sliding sleeve 392 can slide on the third connecting rod 391 and cannot rotate.

[0052] There are two latches 393 and both are plugged into the third connecting rod 391. The two latches 393 are distributed at both ends of the sliding sleeve 392 to abut against each other, thereby limiting the sliding of the sliding sleeve 392 on the third connecting rod 391. The outer wall of the sliding sleeve 392 is fixedly connected to the side plate 394, and the bottom side of the side plate 394 is fixedly connected to one side of the bottom plate 395.

[0053] Reference Figure 7 , Figure 8 The bottom plate 395 is provided with an installation opening 40, and a plurality of extension rods 41 are telescopically arranged inside the installation opening 40, and the plurality of extension rods 41 are closely arranged inside the installation opening 40. A mounting block 42 is provided at one end of the extension rod 41 facing the ring beam 19, and a first plug rod 43 is fixedly installed on a side of the mounting block 42 close to the extension rod 41. A second slot 44 for the first plug rod 43 to be inserted is provided at one end of the extension rod 41 close to the mounting block 42. A ball 45 is installed at one end of the mounting block 42 away from the extension rod 41.

[0054] The second connecting rod 36 is rotated to make the bottom plate 395 close to the side wall of the ring beam 19, and then the locking assembly 38 is locked, thereby limiting the second connecting rod 36 from rotating away from the ring beam 19. Then, the extension rod 41 is pushed to make the ball 45 abut against the side wall of the ring beam 19. When the vehicle body 1 makes a circular motion on the top side of the ring beam 19, the material receiving mechanism 39 makes a circular motion with the vehicle body 1, so that the ball 45 rolls on the side wall of the ring beam 19, thereby reducing the resistance when the vehicle body 1 drives the material receiving mechanism 39 to make a circular motion.

[0055] Reference Figure 7 , Figure 8 , the first plug rod 43 is wrapped with an elastic sleeve 46, a gap is left between the mounting block 42 and the extension rod 41, and a gap is also left between two adjacent mounting blocks 42. A second plug rod 47 is fixedly mounted on the top side of the mounting block 42, and a first shielding piece 48 is provided on the bottom plate 395. The first shielding piece 48 is provided with a socket 50 for the second plug rod 47 to be plugged in, and a second shielding piece 49 is fixedly mounted on the side of the first shielding piece 48 close to the ring beam 19. The second shielding piece 49 is arranged at an angle, and both the first shielding piece 48 and the second shielding piece 49 are elastic, and the second shielding piece 49 is against the side wall of the ring beam 19.

[0056] The first shielding sheet 48 and the second shielding sheet 49 are used to shield the gap, thereby reducing the occurrence of solder leakage. At the same time, when the vehicle body 1 drives the material receiving mechanism 39 to make a circular motion, due to the existence of production errors, the ring beam 19 is actually elliptical, so that the sphere 45 and the side wall of the ring beam 19 are squeezed against each other. By leaving a gap between the mounting block 42 and the extension rod 41, there is also a gap between two adjacent mounting blocks 42, so that the mounting block 42 can be tilted to avoid being squeezed, thereby reducing the situation where the side wall of the ring beam 19 and the sphere 45 are stuck to each other and cannot move.

[0057] Reference Fig. 9 A pressure rod 51 is provided on the bottom side of the bottom plate 395, and a pressure plate 52 is fixedly installed on the rod body of the pressure rod 51. A mounting seat 53 and a bolt 54 are provided at both ends of the pressure rod 51, and the mounting seat 53 is fixedly installed on the bottom surface of the bottom plate 395. The bolt 54 slides through the pressure rod 51, and the bolt 54 is threadedly penetrated on the bottom side of the mounting seat 53. A first avoidance opening 55 for the pressure plate 52 to enter is opened on the bottom surface of the bottom plate 395, and the first avoidance opening 55 is connected to the installation opening 40. After entering from the first avoidance opening 55, the pressure plate 52 presses each extension rod 41.

[0058] Reference Figure 7 , baffles 56 are provided at both ends of the bottom plate 395, and a first slide groove 26 for the baffle 56 to slide through is provided on the top surface of the bottom plate 395. A second avoidance opening 58 for avoiding the baffle 56 is provided on the side plate 394, and the bottom plate 395 is gradually lowered from one end close to the first connecting rod 35 to the other end and is inclined. The baffles 56 are shielded at both ends of the bottom plate 395, thereby reducing the occurrence of solder flux falling from both ends of the bottom plate 395. At the same time, after the solder flux falls into the bottom plate 395, the solder flux is guided by the inclined direction of the bottom plate 395, and the solder flux moves to the baffle 56 away from the first connecting rod 35 and then gathers. The length of the bottom plate 395 is made to cover the position of the welding head 10 and the dust suction pipe 29. After the solder flux gathers on the baffle 56 of the first connecting rod 35 in the yard, the vacuum cleaner 27 will recover the solder flux on the bottom plate 395 through the dust suction pipe 29.

[0059] The implementation principle of the ring beam submerged arc welding machine and the single pile cage manufacturing method of the embodiment of the present application is as follows: after the vehicle body 1 is placed on the top side of the ring beam 19 and the welding head 10 and the dust suction pipe 29 are adjusted toward the connection between the support ring 192 and the cover ring 191. If the welding head 10 welds the connection between the outer support ring 192 and the cover ring 191, the first connecting rod 35 is inserted into the first slot 37 on the outer side of the vehicle body 1; if the welding head 10 welds the connection between the inner support ring 192 and the cover ring 191, the first connecting rod 35 is inserted into the first slot 37 on the inner side of the vehicle body 1.

[0060] After the first connecting rod 35 is inserted into the first slot 37, the second connecting rod 36 is rotated to move toward the ring beam 19, so that the bottom plate 395 is close to the side wall of the ring beam 19. Then, the locking assembly 38 is activated to limit the second connection from rotating away from the ring beam 19.

[0061] After the bottom plate 395 is close to the side wall of the ring beam 19, the baffle plate 56 is pushed to make the baffle plate 56 abut against the side wall of the ring beam 19. Then the extension rod 41 is pushed to make the sphere 45 abut against the side wall of the ring beam 19. After the sphere 45 abuts against the side wall of the ring beam 19, the bolt 54 is passed through the pressure rod 51 and screwed into the mounting seat 53, so that the pressure rod 51 is installed on the bottom side of the bottom plate 395, and after the pressure plate 52 enters the first avoidance opening 55, the pressure plate 52 presses each extension rod 41. Then, the first baffle plate 56 and the second baffle plate are installed on the mounting block 42, and the second baffle plate is abutted against the side wall of the ring beam 19, thereby playing a role in preventing leakage.

[0062] After the soldering solder falls on the connection between the cover ring 191 and the support ring 192, part of the soldering solder falls from the edge of the top side of the ring beam 19 into the bottom plate 395. Then, the soldering solder is guided by the tilted direction of the bottom plate 395, and the soldering solder gathers toward the baffle 56 away from the first connecting rod 35. The soldering solder gathers at the baffle 56 of the first connecting rod 35, so that the vacuum cleaner 27 can absorb the soldering solder on the bottom plate 395 through the vacuum pipe 29, thereby facilitating the recovery of the soldering solder.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
