Description

Technical Field

[0001] This application relates to the technical field of pipe pile welding, and in particular to an automatic pipe pile welding device. Background Art

[0002] Pipe piles are a type of foundation material for buildings, usually driven into the ground as load-bearing members of the building. In some special construction sites, such as the construction site of wind power, due to the limited production length of a single pipe pile, it is usually necessary to weld more than two pipe piles to meet the requirements of on-site construction.

[0003] The existing pipe pile welding mainly relies on manual welding guns held by workers, with low automation and unstable welding quality of pipe piles. There is an urgent need for a welding device that can automatically weld pipe piles to stabilize the welding quality on-site. Summary of the Invention

[0004] In order to improve the automation of on-site pipe pile welding and stabilize the welding quality on-site, this application provides an automatic pipe pile welding device.

[0005] The automatic pipe pile welding device provided by this application adopts the following technical solutions: An automatic pipe pile welding device includes: A first fixing ring is sleeved on one of the pipe piles. At least three first fixing cylinders are connected to the inner wall of the first fixing ring, and the movable ends of the first fixing cylinders are used to press against the pipe pile. A second fixing ring is sleeved on the other pipe pile. At least three second fixing cylinders are connected to the inner wall of the second fixing ring, and the movable ends of the second fixing cylinders are rotatably connected with rollers, and the rollers are used to press against the pipe pile. There are two mounting frames, both of which are arranged between the first fixing ring and the second fixing ring. The mounting frame includes a support rod and a mounting slide. There are two support rods, both of which are slidably penetrated through the mounting slide. One end of the support rod is connected to the second fixing ring, and the other end can slide relative to the first fixing ring. A welding gun is installed on one of the mounting slides, and the position of the welding gun is adjusted as the mounting slide slides. A cleaning grinding head is installed on the other mounting slide, and the position of the cleaning grinding head is adjusted as the mounting slide slides. Wherein, A fixing component is jointly arranged on the two mounting slides. The fixing component is used to fix the mounting slide relative to the support rod by means of the pressing force of the first fixing cylinder pressing against the pipe pile. An adjustment component is commonly provided on the two installation sliding tables. The adjustment component is used to adjust the positions of the welding torch and the cleaning grinding head based on the movement of the movable end of the second fixed oil cylinder, so that the welding torch and the cleaning grinding head can just move to the welding working position; A driving component is commonly provided on the first fixed ring, the second fixed ring and the two mounting brackets. The driving component includes a first driving part and a second driving part. The first driving part is used to drive the second fixed ring and the two mounting brackets to rotate around the pipe pile, and the second driving part is used to drive the cleaning grinding head to rotate by means of the driving force formed by the rotation of the mounting bracket.

[0006] By adopting the above technical solution, the first fixed ring and the second fixed ring are respectively sleeved on the two pipe piles, the installation sliding table is slid, so that the welding torch and the cleaning grinding head are exactly opposite to the welding positions of the two pipe piles. The first fixed oil cylinder and the second fixed oil cylinder extend to automatically fix the first fixed ring and the second fixed ring on the pipe pile. The fixing component makes the installation sliding table fixed relative to the support rod by means of the pressing force of the first fixed oil cylinder pressing against the pipe pile, so as to realize the automatic fixing of the positions of the welding torch and the cleaning grinding head.

[0007] The adjustment component moves the welding torch and the cleaning grinding head to the welding working position based on the movement of the movable end of the second fixed oil cylinder, so as to realize the automatic adjustment of the welding working positions of the welding torch and the cleaning grinding head. The first driving part drives the second fixed ring and the two mounting brackets to rotate around the pipe pile, so that the cleaning grinding head and the welding torch can automatically clean and weld the welding positions of the two pipe piles. The second driving part can drive the cleaning grinding head to rotate by means of the driving force formed by the rotation of the mounting bracket, so that the cleaning grinding head can rotate and sweep by relying on the rotation of the mounting bracket. Thus, after installing the first fixed ring and the second fixed ring and adjusting the welding torch and the cleaning grinding head to be exactly opposite to the welding positions of the pipe pile, the welding torch and the cleaning grinding head can automatically realize the operations of position fixing, position adjustment and cleaning and welding, improve the automation degree of on-site welding of pipe piles, reduce the degree of manual intervention, and further stabilize the quality of on-site welding of pipe piles.

[0008] Since the extension lengths of the first fixed oil cylinder and the second fixed oil cylinder can be adjusted, the first fixed ring and the second fixed ring can be fixed on pipe piles with different diameters, so that the welding device can be used for welding pipe piles with different diameters.

[0009] Optionally, the fixing component includes a flexible box, a double-headed oil cylinder and a fixed pipe; At least three flexible boxes are provided and are connected to the movable ends of the first fixed oil cylinder one by one. Two double-headed oil cylinders are provided and are arranged on the installation sliding table one by one. Flexible blocks are connected to both movable ends of the double-headed oil cylinder; One end of the fixed pipe is connected to all the flexible boxes, and the other end is connected to the middle parts of the two double-headed oil cylinders. The fixed pipe is used to allow a first fluid medium to flow between the flexible boxes and the middle parts of the double-headed oil cylinders. The two rodless chambers of the double-headed oil cylinders are both connected to the atmosphere; Two fixed gears are arranged on each mounting slide. The two fixed gears on each mounting slide are respectively located on one side of the two flexible blocks away from each other. The fixed gears are rotatably connected to the mounting slides. Each fixed gear meshes with a fixed rack. The fixed rack is connected to the support rod close to the fixed gear. When the flexible box abuts against the pipe pile, the flexible block presses against the fixed gear.

[0010] By adopting the above technical solution, when the movable end of the first fixed oil cylinder drives the flexible box to abut against the pipe pile to fix the first fixed ring, the hydraulic oil in the flexible box can be squeezed into the middle part of the double-headed oil cylinder to drive the two movable ends of the double-headed oil cylinder to extend synchronously, so that the flexible blocks on the movable ends of the double-headed oil cylinder can be squeezed into the tooth grooves of the fixed gears, making it difficult for the fixed gears to rotate relative to the mounting slides. Since the fixed gears mesh with the fixed racks, the mounting slides can be automatically fixed to the support rods.

[0011] Optionally, first springs are arranged in the two rodless chambers of the double-headed oil cylinder. The first springs are used to drive the movable ends of the double-headed oil cylinder to contract.

[0012] By adopting the above technical solution, when it is necessary to release the restrictive effect of the flexible block on the fixed gear, the first fixed oil cylinder is contracted. The first spring can drive the double-headed oil cylinder to contract through the elastic force, and the double-headed oil cylinder can drive the flexible block away from the fixed gear to release the restrictive effect of the flexible block on the fixed gear.

[0013] Optionally, the adjusting assembly includes a first adjusting oil cylinder, a first adjusting pipe, a second adjusting oil cylinder and a second adjusting pipe; The first adjusting oil cylinder is connected to the mounting slide where the welding torch is located. The welding torch is connected to the movable end of the first adjusting oil cylinder. The rodless chamber of the first adjusting oil cylinder is connected to the atmosphere. One end of the first adjusting pipe is connected to the rodless chamber of the first adjusting oil cylinder, and the other end is connected to the rodless chambers of all the second fixed oil cylinders. The first adjusting pipe is used to allow a second fluid medium to flow between the rodless chamber of the first adjusting oil cylinder and the rodless chambers of the second fixed oil cylinders; The second adjusting oil cylinder is connected to the mounting slide where the cleaning grinding head is located. The cleaning grinding head is connected to the movable end of the second adjusting oil cylinder. The rodless chamber of the second adjusting oil cylinder is connected to the atmosphere. One end of the second adjusting pipe is connected to the rodless chamber of the second adjusting oil cylinder, and the other end is connected to the rodless chambers of all the second fixed oil cylinders. The second adjusting pipe is used to allow a second fluid medium to flow between the rodless chamber of the second adjusting oil cylinder and the rodless chambers of the second fixed oil cylinders.

[0014] By adopting the above technical solution, when the second fixed oil cylinder extends to make the roller abut against the pipe pile, the second fixed oil cylinder can drive the first adjusting oil cylinder and the second adjusting oil cylinder to extend through hydraulic oil. The first adjusting oil cylinder drives the welding torch to move, and the second adjusting oil cylinder drives the cleaning grinding head to move, so that the welding torch and the cleaning grinding head can automatically adjust the welding working position under the drive of the second fixed oil cylinder.

[0015] Optionally, the adjusting assembly further includes a second spring and a third spring. The second spring is arranged in the rod chamber of the first adjusting oil cylinder, and the second spring is used to drive the first adjusting oil cylinder to contract. The third spring is arranged in the rod chamber of the second adjusting oil cylinder, and the third spring is used to drive the second adjusting oil cylinder to contract.

[0016] By adopting the above technical solution, after the second fixed oil cylinder drives the first adjusting oil cylinder and the second adjusting oil cylinder to extend, the second spring and the third spring can store elastic force. When it is necessary to reset the welding torch and the cleaning grinding head, the driving force for the second fixed oil cylinder to extend is released. Under the action of the elastic force of the second spring and the third spring, the first adjusting oil cylinder and the second adjusting oil cylinder can contract, so that the welding torch and the cleaning grinding head can be easily reset automatically.

[0017] Optionally, the first driving part includes a guiding chute, a gear ring, a first rotating shaft, a first gear, a second gear, a third gear and a motor. The guiding chute is connected to the side of the first fixed ring close to the second fixed ring. The gear ring is arranged in the guiding chute. There are two first rotating shafts, which are respectively rotatably arranged on the two support rods of the mounting rack where the welding torch is located. There are two first gears and two second gears, and they are all in one-to-one correspondence with the first rotating shaft. The first gear is connected to one end of the first rotating shaft. The first gear is slidably arranged in the guiding chute and meshes with the gear ring. The second gear is connected to the other end of the first rotating shaft. The third gear is located between the two second gears and meshes with both second gears. The motor is installed on the second fixed ring, and the output shaft of the motor is connected to the third gear.

[0018] By adopting the above technical solution, the motor drives the third gear to rotate. The third gear drives the two second gears to rotate. The second gear drives the first rotating shaft to rotate. The first rotating shaft drives the first gear to rotate. Under the drive of the gear ring, the first gear rotates around the pipe pile in the guiding chute, so that the mounting rack and the second fixed ring can rotate around the pipe pile.

[0019] Optionally, the second driving part includes a second rotating shaft, a fourth gear, a synchronous pulley, a cleaning pulley and a synchronous driving belt. There are two second rotating shafts, which are respectively rotatably inserted through two support rods of the mounting frame where the cleaning grinding head is located. There are two fourth gears and two synchronous pulleys, and they are all in one-to-one correspondence with the second rotating shafts. The fourth gear is connected to one end of the second rotating shaft. The fourth gear is slidably arranged in the guiding chute and meshes with the toothed ring. The synchronous pulley is slidably sleeved on the second rotating shaft. The second rotating shaft is used to drive the synchronous pulley to rotate. The synchronous pulley is slidably arranged in a relief sliding hole opened on the support rod. The cleaning grinding head is rotatably connected to the movable end of the second adjusting oil cylinder. The cleaning pulley is connected to the cleaning grinding head. The synchronous driving belt is wound around the two synchronous pulleys and the cleaning pulley.

[0020] By adopting the above technical solution, when the two mounting frames and the second fixed ring rotate around the pipe pile, the fourth gear can rotate under the drive of the toothed ring. The fourth gear drives the second rotating shaft to rotate. The second rotating shaft drives the synchronous pulley to rotate. The synchronous pulley drives the synchronous driving belt to rotate. The synchronous driving belt drives the cleaning pulley to rotate. The cleaning pulley drives the cleaning grinding head to rotate. Thus, the cleaning grinding head can utilize the driving force formed by the rotation of the mounting frame, so that the cleaning grinding head can automatically rotate when the welding torch rotates for welding.

[0021] Optionally, a tension pulley is wound around the inner side of the synchronous driving belt. The tension pulley is connected with a telescopic rod, and the tension pulley is rotatably connected to the movable end of the telescopic rod. The telescopic rod is connected to the mounting slide table. A fourth spring is arranged in the rodless cavity of the telescopic rod. The fourth spring is used to drive the telescopic rod to extend.

[0022] By adopting the above technical solution, when the second adjusting oil cylinder adjusts the position of the cleaning grinding head, the cleaning grinding head can make the cleaning pulley approach the pipe pile synchronously. The cleaning pulley can push the synchronous driving belt to approach the pipe pile. Since the perimeter of the synchronous driving belt is fixed, the synchronous driving belt can pull the tension pulley to approach the pipe pile. The tension pulley drives the telescopic rod to contract, so that the fourth spring accumulates elastic force. Under the elastic force of the fourth spring, the synchronous driving belt can always be in a tensioned state, thus making it difficult for the synchronous driving belt to affect the adjustment of the position of the cleaning grinding head.

[0023] Optionally, the first fixed ring and the second fixed ring have the same structure. The first fixed ring includes two fixed half rings. One ends of the two fixed half rings are hinged, and the other ends are detachably connected.

[0024] By adopting the above technical solution, since both the first fixed ring and the second fixed ring can be disassembled into two fixed half rings, it is convenient for the first fixed ring and the second fixed ring to be sleeved on the pipe pile, improving the installation convenience of the first fixed ring and the second fixed ring.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the first fixed ring, the second fixed ring, the mounting bracket, the fixing component, the adjusting component and the driving component, the welding torch and the cleaning grinding head can be automatically adjusted to the welding working state, improving the automation degree of on-site welding of pipe piles. 2. By setting the first driving part and the second driving part, the cleaning grinding head can grind and sweep the welding position of the pipe pile. Brief Description of the Drawings

Detailed Embodiment

[0028] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0029] An embodiment of the present application discloses an automatic pipe pile welding device. Refer to Figure 1, An automatic pipe pile welding device includes a first fixing ring 1, a second fixing ring 2, a mounting frame 3, a welding torch 4 and a cleaning grinding head 5.

[0030] The first fixing ring 1 is sleeved on one of the pipe piles. Four first fixing oil cylinders 11 are fixedly connected to the inner wall of the first fixing ring 1, and the movable ends of the first fixing oil cylinders 11 are used to press tightly against the pipe pile. The second fixing ring 2 is sleeved on the other pipe pile. Four second fixing oil cylinders 21 are fixedly connected to the inner wall of the second fixing ring 2, and the movable ends of the second fixing oil cylinders 21 are rotatably connected with rollers 22, and the rollers 22 are used to press tightly against the pipe pile. The first fixing ring 1 is fixed relative to the pipe pile, and the second fixing ring 2 can rotate relative to the pipe pile, so that the second fixing ring 2 can rotate around the pipe pile with the first fixing ring 1 as the support, enabling the welding torch 4 and the cleaning grinding head 5 to rotate around the pipe pile.

[0031] There are two mounting frames 3, and both of the two mounting frames 3 are arranged between the first fixing ring 1 and the second fixing ring 2. The mounting frame 3 includes a support rod 31 and a mounting slide 32. There are two support rods 31, and both are slidably inserted through the mounting slide 32. One end of the support rod 31 is fixedly connected to the second fixing ring 2, and the other end can slide relative to the first fixing ring 1. The welding torch 4 is installed on one of the mounting slides 32, and the position of the welding torch 4 is adjusted as the mounting slide 32 slides. The cleaning grinding head 5 is installed on the other mounting slide 32, and the position of the cleaning grinding head 5 is adjusted as the mounting slide 32 slides. By setting the mounting frame 3, the welding torch 4 and the cleaning grinding head 5 are convenient to rotate following the second fixing ring 2, and the welding torch 4 and the cleaning grinding head 5 can move to the welding positions of the two pipe piles.

[0032] Among them, the cleaning grinding head 5 is a flexible grinding and sweeping member. For example, the cleaning grinding head 5 is made of wire drawing cloth, or the inside of the cleaning grinding head 5 is made of sponge and the outer surface layer is made of emery.

[0033] A fixing component 6 is jointly arranged on the two mounting slides 32. The fixing component 6 is used to fix the mounting slide 32 relative to the support rod 31 by means of the pressing force of the first fixing oil cylinder 11 pressing tightly against the pipe pile.

[0034] An adjusting component 7 is jointly arranged on the two mounting slides 32. The adjusting component 7 is used to adjust the positions of the welding torch 4 and the cleaning grinding head 5 based on the movement of the movable end of the second fixing oil cylinder 21, so that the welding torch 4 and the cleaning grinding head 5 can just move to the welding working positions.

[0035] Refer to Figure 2, a driving assembly 8 is jointly provided on the first fixing ring 1, the second fixing ring 2 and the two mounting brackets 3. The driving assembly 8 includes a first driving part 81 and a second driving part 82. The first driving part 81 is used to drive the second fixing ring 2 and the two mounting brackets 3 to rotate around the pipe pile, and the second driving part 82 is used to drive the cleaning grinding head 5 to rotate by means of the driving force formed by the rotation of the mounting bracket 3.

[0036] During use, the first fixing ring 1 and the second fixing ring 2 are respectively sleeved on the two pipe piles, and the sliding table 32 is slidably installed so that the welding torch 4 and the cleaning grinding head 5 are aligned with the welding positions of the two pipe piles. The first fixing oil cylinder 11 and the second fixing oil cylinder 21 extend to automatically fix the first fixing ring 1 and the second fixing ring 2 on the pipe pile. The fixing assembly 6 fixes the mounting slide 32 relative to the support rod 31 by means of the pressing force of the first fixing oil cylinder 11 pressing against the pipe pile, so as to realize the automatic fixing of the positions of the welding torch 4 and the cleaning grinding head 5.

[0037] The adjusting assembly 7 moves the welding torch 4 and the cleaning grinding head 5 to the welding working position based on the movement of the movable end of the second fixing oil cylinder 21, so as to realize the automatic adjustment of the welding working positions of the welding torch 4 and the cleaning grinding head 5. The first driving part 81 drives the second fixing ring 2 and the two mounting brackets 3 to rotate around the pipe pile, so that the cleaning grinding head 5 and the welding torch 4 can automatically clean and weld the welding positions of the two pipe piles. The second driving part 82 can drive the cleaning grinding head 5 to rotate by means of the driving force formed by the rotation of the mounting bracket 3, so that the cleaning grinding head 5 can perform rotary grinding by relying on the rotation of the mounting bracket 3. Therefore, after the first fixing ring 1 and the second fixing ring 2 are installed and the welding torch 4 and the cleaning grinding head 5 are adjusted to be aligned with the welding positions of the pipe pile, the welding torch 4 and the cleaning grinding head 5 can automatically realize the operations of position fixing, position adjustment and cleaning welding, improving the automation degree of on-site welding of pipe piles, reducing the degree of manual intervention, and thus stabilizing the quality of on-site welding of pipe piles.

[0038] Since the extending lengths of the first fixing oil cylinder 11 and the second fixing oil cylinder 21 can be adjusted, the first fixing ring 1 and the second fixing ring 2 can be fixed on pipe piles with different diameters, so that the welding device can be used for welding pipe piles with different diameters.

[0039] In particular, referring to Figure 2 , the first fixing ring 1 and the second fixing ring 2 have the same structure. The first fixing ring 1 includes two fixing half rings 12. One end of the two fixing half rings 12 is hinged, and the other end is detachably connected.

[0040] A padlock buckle 13 is arranged between the ends of the two fixing half rings 12 far from the hinge. The hook body of the padlock buckle 13 is fixedly connected to one of the fixing half rings 12, and the lock body of the padlock buckle 13 is fixedly connected to the other fixing half ring 12. The padlock buckle 13 forms a detachable connection structure for the two fixing half rings 12.

[0041] Since both the first fixing ring 1 and the second fixing ring 2 can be disassembled into two fixing half-rings 12, the first fixing ring 1 and the second fixing ring 2 are convenient to be sleeved on the pipe pile, improving the installation convenience of the first fixing ring 1 and the second fixing ring 2.

[0042] Specifically, referring to Figure 2 and Figure 3 , the fixing assembly 6 includes a flexible box 61, a double-headed oil cylinder 62 and a fixing pipe 63.

[0043] Four flexible boxes 61 are provided and are fixedly connected to the movable ends of the first fixing oil cylinders 11 one by one. The movable ends of the first fixing oil cylinders 11 press against the side wall of the pipe pile with the flexible boxes 61, increasing the pressing force between the movable ends of the first fixing oil cylinders 11 and the pipe pile. Two double-headed oil cylinders 62 are provided and are fixedly arranged in the relief holes 321 formed in the mounting sliding tables 32 one by one. Flexible blocks 621 are fixedly connected to the two movable ends of the double-headed oil cylinder 62.

[0044] One end of the fixing pipe 63 is communicated with all the flexible boxes 61, and the other end is communicated with the middle parts of the two double-headed oil cylinders 62. The fixing pipe 63 is used to allow a first fluid medium to flow between the flexible boxes 61 and the middle parts of the double-headed oil cylinders 62. The two rodless cavities of the double-headed oil cylinder 62 are communicated with the atmosphere. When the flexible box 61 is squeezed, the flexible box 61 can drive the two movable ends of the double-headed oil cylinder 62 to extend synchronously by means of the first fluid medium. The first fluid medium is hydraulic oil in this application.

[0045] Two fixing gears 64 are provided on each mounting sliding table 32. The two fixing gears 64 on each mounting sliding table 32 are respectively located on the sides away from each other of the two flexible blocks 621. The fixing gears 64 are rotatably connected to the mounting sliding tables 32 and are located in the relief holes 321. Each fixing gear 64 meshes with a fixing rack 65, and the fixing rack 65 is fixedly connected to the support rod 31 close to the fixing gear 64. When the flexible box 61 presses against the pipe pile, the flexible block 621 presses against the fixing gear 64, and the flexible block 621 is pressed into the tooth grooves of the fixing gear 64 to limit the rotation of the fixing gear 64.

[0046] When the movable end of the first fixing oil cylinder 11 drives the flexible box 61 to press against the pipe pile to fix the first fixing ring 1, the hydraulic oil in the flexible box 61 can be squeezed into the middle part of the double-headed oil cylinder 62 to drive the two movable ends of the double-headed oil cylinder 62 to extend synchronously, so that the flexible block 621 on the movable end of the double-headed oil cylinder 62 can be pressed into the tooth grooves of the fixing gear 64, making it difficult for the fixing gear 64 to rotate relative to the mounting sliding table 32. Since the fixing gear 64 meshes with the fixing rack 65, the mounting sliding table 32 can be automatically fixed to the support rod 31.

[0047] Furthermore, referring toFigure 3 In both rod chambers of the double-headed oil cylinder 62, a first spring 66 is provided. One end of the first spring 66 is fixedly connected to the fixed end of the double-headed oil cylinder 62, and the other end is fixedly connected to the movable end of the double-headed oil cylinder 62. The first spring 66 is used to drive the contraction of the movable end of the double-headed oil cylinder 62.

[0048] When it is necessary to release the restrictive effect of the flexible block 621 on the fixed gear 64, the first fixed oil cylinder 11 is contracted. The first spring 66 can drive the double-headed oil cylinder 62 to contract through its elastic force. The double-headed oil cylinder 62 can drive the flexible block 621 away from the fixed gear 64 to release the restriction of the flexible block 621 on the fixed gear 64.

[0049] Specifically, referring to Figure 2 、 Figure 3 and Figure 4 the adjustment assembly 7 includes a first adjustment oil cylinder 71, a first adjustment pipe 72, a second adjustment oil cylinder 73 and a second adjustment pipe 74.

[0050] Referring to Figure 2 and Figure 4 the first adjustment oil cylinder 71 is fixedly connected to the mounting slide 32 where the welding torch 4 is located. The welding torch 4 is fixedly connected to the movable end of the first adjustment oil cylinder 71. The rod chamber of the first adjustment oil cylinder 71 communicates with the atmosphere. One end of the first adjustment pipe 72 is connected to the rodless chamber of the first adjustment oil cylinder 71, and the other end is connected to the rod chambers of all the second fixed oil cylinders 21. The first adjustment pipe 72 is used to allow a second fluid medium to flow between the rodless chamber of the first adjustment oil cylinder 71 and the rod chambers of the second fixed oil cylinders 21. The first adjustment oil cylinder 71 can adjust the position of the welding torch 4 under the drive of the second fixed oil cylinders 21.

[0051] Referring to Figure 2 and Figure 3 the second adjustment oil cylinder 73 is fixedly connected to the mounting slide 32 where the cleaning grinding head 5 is located. The cleaning grinding head 5 is connected to the movable end of the second adjustment oil cylinder 73. The rod chamber of the second adjustment oil cylinder 73 communicates with the atmosphere. One end of the second adjustment pipe 74 is connected to the rodless chamber of the second adjustment oil cylinder 73, and the other end is connected to the rod chambers of all the second fixed oil cylinders 21. The second adjustment pipe 74 is used to allow a second fluid medium to flow between the rodless chamber of the second adjustment oil cylinder 73 and the rod chambers of the second fixed oil cylinders 21. The second fluid medium is hydraulic oil in this application. The second adjustment oil cylinder 73 can adjust the position of the cleaning grinding head 5 under the drive of the second fixed oil cylinders 21.

[0052] When the second fixed oil cylinder 21 extends to make the roller 22 abut against the pipe pile, the second fixed oil cylinder 21 can drive the first adjusting oil cylinder 71 and the second adjusting oil cylinder 73 to extend through hydraulic oil. The first adjusting oil cylinder 71 drives the welding torch 4 to move, and the second adjusting oil cylinder 73 drives the cleaning grinding head 5 to move, so that the welding torch 4 and the cleaning grinding head 5 can automatically adjust the welding working position under the drive of the second fixed oil cylinder 21.

[0053] Further, referring to Figure 3 and Figure 4 , the adjusting assembly 7 further includes a second spring 75 and a third spring 76. The second spring 75 is arranged in the rod chamber of the first adjusting oil cylinder 71. One end of the second spring 75 is fixedly connected to the fixed end of the first adjusting oil cylinder 71, and the other end is fixedly connected to the movable end of the first adjusting oil cylinder 71. The second spring 75 is used to drive the first adjusting oil cylinder 71 to contract. The third spring 76 is arranged in the rod chamber of the second adjusting oil cylinder 73. One end of the third spring 76 is fixedly connected to the fixed end of the second adjusting oil cylinder 73, and the other end is fixedly connected to the movable end of the second adjusting oil cylinder 73. The third spring 76 is used to drive the second adjusting oil cylinder 73 to contract.

[0054] After the second fixed oil cylinder 21 drives the first adjusting oil cylinder 71 and the second adjusting oil cylinder 73 to extend, the second spring 75 and the third spring 76 can store elastic force. When it is necessary to reset the welding torch 4 and the cleaning grinding head 5, the driving force for the second fixed oil cylinder 21 to extend is released. Under the action of the elastic force of the second spring 75 and the third spring 76, the first adjusting oil cylinder 71 and the second adjusting oil cylinder 73 can contract, so that the welding torch 4 and the cleaning grinding head 5 can be easily reset automatically.

[0055] Specifically, referring to Figure 2 and Figure 4 , the first driving part 81 includes a guiding chute 811, a gear ring 812, a first rotating shaft 813, a first gear 814, a second gear 815, a third gear 816 and a motor 817.

[0056] The guiding chute 811 is fixedly connected to one side of the first fixing ring 1 close to the second fixing ring 2. The gear ring 812 is fixedly arranged in the guiding chute 811. There are two first rotating shafts 813, which are respectively rotatably arranged on two support rods 31 of the mounting bracket 3 where the welding torch 4 is located. There are two first gears 814 and two second gears 815, and they are all in one-to-one correspondence with the first rotating shaft 813. The first gear 814 is fixedly connected to one end of the first rotating shaft 813. The first gear 814 is slidably arranged in the guiding chute 811 and meshes with the gear ring 812. The second gear 815 is fixedly connected to the other end of the first rotating shaft 813. The third gear 816 is located between the two second gears 815 and meshes with both of the second gears 815. The motor 817 is fixedly connected to the second fixing ring 2, and the output shaft of the motor 817 is fixedly connected to the third gear 816.

[0057] When welding, the motor 817 is started. The motor 817 drives the third gear 816 to rotate. The third gear 816 drives the two second gears 815 to rotate. The second gear 815 drives the first rotating shaft 813 to rotate. The first rotating shaft 813 drives the first gear 814 to rotate. Driven by the tooth ring 812, the first gear 814 rotates around the pipe pile within the guiding chute 811, so that the mounting bracket 3 and the second fixing ring 2 can rotate around the pipe pile.

[0058] Specifically, the guiding chute 811 includes two semi-circular semi-guiding chutes, which are respectively and fixedly arranged on the two fixing semi-rings 12 of the first fixing ring 1. Through the two semi-guiding chutes, the guiding chute 811 is convenient to be sleeved on the pipe pile; the tooth ring 812 includes two semi-circular semi-tooth rings, which are respectively and fixedly arranged in the two semi-guiding chutes. Through the two semi-tooth rings, the tooth ring 812 is convenient to be sleeved on the pipe pile.

[0059] Specifically, referring to Figure 2 、 Figure 3 and Figure 5 Figure, the second driving part 82 includes a second rotating shaft 821, a fourth gear 822, a synchronous pulley 823, a cleaning pulley 824 and a synchronous driving belt 825.

[0060] There are two second rotating shafts 821, which are respectively rotatably inserted through the two support rods 31 of the mounting bracket 3 where the cleaning grinding head 5 is located. There are two fourth gears 822 and two synchronous pulleys 823, and they are in one-to-one correspondence with the second rotating shaft 821 respectively. The fourth gear 822 is fixedly connected to one end of the second rotating shaft 821. The fourth gear 822 is slidably arranged in the guiding chute 811 and meshes with the tooth ring 812. The synchronous pulley 823 is slidably sleeved on the second rotating shaft 821. The second rotating shaft 821 is used to drive the synchronous pulley 823 to rotate. The synchronous pulley 823 is slidably arranged in the relief sliding hole 311 opened on the support rod 31. The cleaning grinding head 5 is rotatably connected to the movable end of the second adjusting oil cylinder 73. The cleaning pulley 824 is fixedly connected to the cleaning grinding head 5. The synchronous driving belt 825 is wound around the two synchronous pulleys 823 and the cleaning pulley 824.

[0061] When the two mounting brackets 3 and the second fixing ring 2 rotate around the pipe pile, the fourth gear 822 can rotate driven by the tooth ring 812. The fourth gear 822 drives the second rotating shaft 821 to rotate. The second rotating shaft 821 drives the synchronous pulley 823 to rotate. The synchronous pulley 823 drives the synchronous driving belt 825 to rotate. The synchronous driving belt 825 drives the cleaning pulley 824 to rotate. The cleaning pulley 824 drives the cleaning grinding head 5 to rotate. Thus, the cleaning grinding head 5 can utilize the driving force formed by the rotation of the mounting bracket 3, so that the cleaning grinding head 5 can automatically rotate when the welding torch 4 rotates for welding.

[0062] In particular, referring to Figure 3 , a slider 8231 is fixedly connected to the synchronous pulley 823. The slider 8231 is slidably arranged in an adjustment chute 8211 formed on the second rotating shaft 821. Through the clamping action between the slider 8231 and the adjustment chute 8211, the second rotating shaft 821 can drive the synchronous pulley 823 to rotate.

[0063] Furthermore, referring to Figure 3 , a tension pulley 826 is wound around the inner side of the synchronous drive belt 825. The tension pulley 826 is connected to a telescopic rod 827, and the tension pulley 826 is rotatably connected to the movable end of the telescopic rod 827. The telescopic rod 827 is fixedly connected to the mounting slide 32. A fourth spring 828 is arranged in the rodless cavity of the telescopic rod 827. One end of the fourth spring 828 is fixedly connected to the fixed end of the telescopic rod 827, and the other end is fixedly connected to the movable end of the telescopic rod 827. The fourth spring 828 is used to drive the telescopic rod 827 to extend.

[0064] When the second adjustment oil cylinder 73 adjusts the position of the cleaning grinding head 5, the cleaning grinding head 5 can synchronously approach the pipe pile, and the cleaning pulley 824 can push the synchronous drive belt 825 closer to the pipe pile. Since the circumference of the synchronous drive belt 825 is fixed, the synchronous drive belt 825 can pull the tension pulley 826 closer to the pipe pile, and the tension pulley 826 drives the telescopic rod 827 to contract, so that the fourth spring 828 accumulates elastic force. Under the elastic force of the fourth spring 828, the synchronous drive belt 825 can always be in a tensioned state, so that the synchronous drive belt 825 is not likely to affect the adjustment of the position of the cleaning grinding head 5.

[0065] The implementation principle of an automatic pipe pile welding device according to an embodiment of the present application is as follows: During use, the first fixing ring 1 and the second fixing ring 2 are sleeved on the pipe pile, and the mounting slide 32 is slid so that the welding torch 4 and the cleaning grinding head 5 are both opposite to the welding positions of the two pipe piles. The first fixing oil cylinder 11 fixes the first fixing ring 1 on the pipe pile and fixes the mounting slide 32 and the support rod 31. The second fixing oil cylinder 21 fixes the second fixing ring 2 on the pipe pile and adjusts the welding torch 4 and the cleaning grinding head 5 to the welding working positions. The motor 817 is started, and the motor 817 drives the mounting frame 3 and the second fixing ring 2 to rotate around the pipe pile. The cleaning grinding head 5 rotates by virtue of the driving force formed by the rotation of the mounting frame 3. The cleaning grinding head 5 grinds and cleans the welding joint of the pipe pile, and the welding torch 4 welds the pipe pile, thereby improving the automation degree of on-site welding of the pipe pile and making it easy to stabilize the welding quality of the pipe pile.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
