Description

Technical Field

[0001] The present 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 used in buildings. They are typically sunk into the ground to serve as load-bearing structures. In some special construction situations, longer pipe piles are required. For example, at wind turbine construction sites, due to the limited length of a single pipe pile, two or more pipe piles must be welded together to meet on-site construction requirements.

[0003] Existing pipe pile welding mainly relies on manual handheld welding guns, which has a low degree of automation and easily leads to unstable pipe pile welding quality. Currently, there is an urgent need for a welding device that can automatically weld pipe piles to stabilize the quality of pipe pile on-site welding. Summary of the Invention

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

[0005] The present application provides an automatic pipe pile welding device, which adopts the following technical solutions:

[0008] A second fixing ring is sleeved on another pipe pile, and at least three second fixing cylinders are connected to the inner wall of the second fixing ring. The movable ends of the second fixing cylinders are rotatably connected to rollers, and the rollers are used to press against the pipe pile;

[0009] There are two mounting brackets, both of which are arranged between the first fixing ring and the second fixing ring. The mounting brackets include a support rod and a mounting slide. There are two support rods, both of which are slidably inserted into 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.

[0010] A welding gun is mounted on one of the mounting slides, and the position of the welding gun is adjusted as the mounting slide slides;

[0011] The cleaning grinding head is mounted on another mounting slide, and the position of the cleaning grinding head is adjusted as the mounting slide slides;

[0012] in,

[0013] The two installation slides are provided with a fixing assembly, which is used to fix the installation slide relative to the support rod by means of the pressing force of the first fixing oil cylinder against the pipe pile;

[0014] The two mounting slides are provided with an adjustment component, which is used to adjust the position of the welding gun and the cleaning grinding head based on the movement of the movable end of the second fixed oil cylinder, so that the welding gun and the cleaning grinding head can be moved to the welding working position exactly;

[0015] A driving assembly is commonly provided on the first fixing ring, the second fixing ring and the two mounting frames. The driving assembly includes a first driving part and a second driving part. The first driving part is used to drive the second fixing ring and the two mounting frames to rotate around the pipe pile, and the second driving part is used to drive the cleaning grinding head to rotate with the driving force generated by the rotation of the mounting frames.

[0016] By adopting the above technical solution, the first fixing ring and the second fixing ring are respectively mounted on the two pipe piles, and the sliding installation slide is slid so that the welding gun and the cleaning grinding head are aligned with the welding positions of the two pipe piles. The first fixing oil cylinder and the second fixing oil cylinder are extended to automatically fix the first fixing ring and the second fixing ring on the pipe pile. The fixing assembly uses the pressing force of the first fixing oil cylinder to press against the pipe pile to fix the installation slide relative to the support rod, thereby realizing automatic fixation of the welding gun position and the cleaning grinding head position.

[0017] The adjusting component moves the welding gun 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 automatic adjustment of the welding working position of the welding gun and the cleaning grinding head. The first driving part drives the second fixed ring and the two mounting frames to rotate around the pipe pile, so that the cleaning grinding head and the welding gun 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 with the driving force generated by the rotation of the mounting frame, so that the cleaning grinding head can rotate and grind by relying on the rotation of the mounting frame. After installing the first fixed ring and the second fixed ring and adjusting the welding gun and the cleaning grinding head to the welding position of the pipe pile, the welding gun and the cleaning grinding head can automatically realize the position fixing, position adjustment and cleaning welding operations, which improves the degree of automation of on-site welding of pipe piles, reduces the degree of manual intervention, and thus stabilizes the quality of on-site welding of pipe piles.

[0018] Since the extension lengths of the first fixing cylinder and the second fixing cylinder can be adjusted, the first fixing ring and the second fixing ring can be fixed on pipe piles of different diameters, so that the welding device can be used to weld pipe piles of different diameters.

[0019] Optionally, the fixing assembly includes a flexible box, a double-headed oil cylinder and a fixing pipe;

[0020] There are at least three flexible boxes, which are connected to the movable end of the first fixed oil cylinder in a one-to-one correspondence. There are two double-headed oil cylinders, which are arranged on the mounting slide in a one-to-one correspondence. Flexible blocks are connected to the two movable ends of the double-headed oil cylinders.

[0021] One end of the fixed pipe is connected to all the flexible boxes, and the other end is connected to the middle of the two double-headed oil cylinders.

[0022] Two fixed gears are provided on each mounting slide. The two fixed gears on each mounting slide are respectively located on the side of the two flexible blocks away from each other. The fixed gears are rotatably connected to the mounting slide. Each fixed gear is engaged with a fixed rack, and the fixed rack is connected to the support rod close to the fixed gear. When the flexible box is pressed against the pipe pile, the flexible block is squeezed on the fixed gear.

[0023] By adopting the above technical solution, when the movable end of the first fixed oil cylinder drives the flexible box to press against the pipe pile to fix the first fixed ring, the hydraulic oil in the flexible box can be squeezed to 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 block on the movable end of the double-headed oil cylinder can be squeezed into the tooth groove of the fixed gear, making it difficult for the fixed gear to rotate relative to the mounting slide. Since the fixed gear is engaged with the fixed rack, the mounting slide can be automatically fixed to the support rod.

The rod cavity of the first regulating oil cylinder is connected to the atmosphere. One end of the first regulating oil cylinder is connected to the rodless cavity of the first regulating oil cylinder, and the other end is connected to the rod cavities of all the second fixed oil cylinders. The first regulating oil cylinder is used to allow a second fluid medium to flow between the rodless cavity of the first regulating oil cylinder and the rod cavities of the second fixed oil cylinders.

The second adjusting tube is used to allow a second fluid medium to flow between the rodless chamber of the second adjusting cylinder and the rod chamber of the second fixed cylinder.

[0029] By adopting the above technical solution, when the second fixed oil cylinder is extended 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 gun to move, and the second adjusting oil cylinder drives the cleaning grinding head to move, so that the welding gun and the cleaning grinding head can realize automatic adjustment of the welding working position under the drive of the second fixed oil cylinder.

[0031] 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 accumulate elastic force. When it is necessary to reset the welding gun and the cleaning grinding head, the driving force for extending the second fixed oil cylinder 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 be retracted, thereby facilitating the automatic reset of the welding gun and the cleaning grinding head.

[0033] 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, and the first rotating shaft drives the first gear to rotate. Under the drive of the ring gear, the first gear rotates around the pipe pile in the guide groove, so that the mounting frame and the second fixing ring can rotate around the pipe pile.

[0034] Optionally, the second driving part includes a second rotating shaft, a fourth gear, a synchronous pulley, a cleaning pulley and a synchronous drive belt. The second rotating shaft is provided with two, and they are respectively rotatable and passed through the 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 correspond one to one with the second rotating shaft. The fourth gear is connected to one end of the second rotating shaft, and the fourth gear is slidably set in the guide groove and meshes with the gear ring.

Since the circumference of the synchronous drive belt is fixed, the synchronous drive belt can pull the tensioning pulley close to the pipe pile, and the tensioning pulley drives the telescopic rod to contract, so that the fourth spring accumulates elastic force. Under the action of the elastic force of the fourth spring, the synchronous drive belt can always be in a tensioned state, so that the synchronous drive belt is not easy to affect the adjustment of the position of the cleaning grinding head.

DETAILED DESCRIPTION

[0050] The following is combined with Figure 1-5 This application is described in further detail.

[0051] The embodiment of the present application discloses an automatic welding device for pipe piles. Figure 1 A pipe pile automatic welding device includes a first fixing ring 1, a second fixing ring 2, a mounting frame 3, a welding gun 4 and a cleaning grinding head 5.

[0052] A first fixing ring 1 is mounted on one of the piles. Four first fixing cylinders 11 are fixedly connected to the inner wall of the first fixing ring 1. The movable ends of the first fixing cylinders 11 are used to press against the pile. A second fixing ring 2 is mounted on the other pile. Four second fixing cylinders 21 are fixedly connected to the inner wall of the second fixing ring 2. The movable ends of the second fixing cylinders 21 are rotatably connected to rollers 22, which are used to press against the pile. The first fixing ring 1 is fixed relative to the pile, while the second fixing ring 2 is rotatable relative to the pile. This allows the second fixing ring 2 to rotate the welding gun 4 and the cleaning grinding head 5 around the pile, using the first fixing ring 1 as support.

[0053] There are two mounting frames 3, both of which are arranged between the first fixing ring 1 and the second fixing ring 2. The mounting frames 3 include support rods 31 and mounting slides 32. There are two support rods 31, both of which are slidably inserted into the mounting slides 32. One end of the support rod 31 is fixed to the second fixing ring 2, and the other end can slide relative to the first fixing ring 1. The welding gun 4 is mounted on one of the mounting slides 32, and the position of the welding gun 4 is adjusted as the mounting slide 32 slides. The cleaning grinding head 5 is mounted on the other mounting slide 32, and the position of the cleaning grinding head 5 is adjusted as the mounting slide 32 slides. By providing the mounting frame 3, the welding gun 4 and the cleaning grinding head 5 can be easily rotated with the second fixing ring 2, and the welding gun 4 and the cleaning grinding head 5 can be moved to the welding position of the two pipe piles.

[0054] The cleaning grinding head 5 is a flexible grinding and sweeping member. For example, the cleaning grinding head 5 is made of brushed cloth, or the interior of the cleaning grinding head 5 is made of sponge and the outer surface is made of corundum.

[0055] A fixing assembly 6 is commonly provided on the two installation slides 32 . The fixing assembly 6 is used to fix the installation slides 32 relative to the support rod 31 by means of the pressing force of the first fixing oil cylinder 11 against the pipe pile.

[0056] An adjustment assembly 7 is commonly provided on the two mounting slides 32, and the adjustment assembly 7 is used to adjust the position of the welding gun 4 and the cleaning grinding head 5 based on the movement of the movable end of the second fixed oil cylinder 21, so that the welding gun 4 and the cleaning grinding head 5 can be moved to the welding working position just right.

[0057] Reference Figure 2A driving assembly 8 is commonly provided on the first fixing ring 1, the second fixing ring 2 and the two mounting frames 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 frames 3 to rotate around the pipe pile, and the second driving part 82 is used to drive the cleaning grinding head 5 to rotate with the help of the driving force generated by the rotation of the mounting frame 3.

[0058] When in use, the first fixing ring 1 and the second fixing ring 2 are respectively placed on the two pipe piles, and the installation slide 32 is slid so that the welding gun 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 are extended to automatically fix the first fixing ring 1 and the second fixing ring 2 on the pipe piles. The fixing assembly 6 uses the pressing force of the first fixing oil cylinder 11 to press against the pipe pile to fix the installation slide 32 relative to the support rod 31, so as to realize the automatic fixation of the position of the welding gun 4 and the cleaning grinding head 5.

[0059] The adjusting component 7 moves the welding gun 4 and the cleaning grinding head 5 to the welding working position based on the movement of the movable end of the second fixed oil cylinder 21, so as to realize automatic adjustment of the welding working position of the welding gun 4 and the cleaning grinding head 5. The first driving part 81 drives the second fixed ring 2 and the two mounting frames 3 to rotate around the pipe pile, so that the cleaning grinding head 5 and the welding gun 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 with the driving force generated by the rotation of the mounting frame 3, so that the cleaning grinding head 5 can rotate and grind by relying on the rotation of the mounting frame 3. After installing the first fixed ring 1 and the second fixed ring 2 and adjusting the welding gun 4 and the cleaning grinding head 5 to the welding position of the pipe pile, the welding gun 4 and the cleaning grinding head 5 can automatically realize the position fixing, position adjustment and cleaning welding operations, thereby improving the degree of automation 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.

[0060] Since the extension lengths of the first fixing cylinder 11 and the second fixing cylinder 21 can be adjusted, the first fixing ring 1 and the second fixing ring 2 can be fixed on pipe piles of different diameters, so that the welding device can be used to weld pipe piles of different diameters.

[0061] In particular, refer 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.

[0062] A padlock hasp 13 is provided between the ends of the two fixed half rings 12 away from the hinge. The hook body of the padlock hasp 13 is fixedly connected to one of the fixed half rings 12, and the lock body of the padlock hasp 13 is fixedly connected to the other fixed half ring 12. The padlock hasp 13 forms a detachable connection structure of the two fixed half rings 12.

[0063] Since 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 can be easily sleeved on the pipe pile, thereby improving the installation convenience of the first fixing ring 1 and the second fixing ring 2.

[0064] Specifically, refer 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 .

[0065] Four flexible boxes 61 are provided, each correspondingly fixed to the movable end of the first fixed oil cylinder 11. The movable end of the first fixed oil cylinder 11 is pressed against the side wall of the pile by the flexible boxes 61, increasing the contact force between the movable end of the first fixed oil cylinder 11 and the pile. Two double-ended oil cylinders 62 are provided, each correspondingly fixed within the clearance holes 321 provided in the mounting slide 32. Flexible blocks 621 are fixed to each movable end of the double-ended oil cylinder 62.

[0066] One end of a fixed tube 63 is connected to all of the flexible boxes 61, and the other end is connected to the center of both double-ended cylinders 62. This tube 63 allows a first fluid medium to flow between the flexible boxes 61 and the center of the double-ended cylinders 62. Both rod chambers of the double-ended cylinders 62 are connected to the atmosphere. When the flexible boxes 61 are squeezed, the first fluid medium drives the two movable ends of the double-ended cylinders 62 to extend synchronously. In this application, the first fluid medium is hydraulic oil.

[0067] Each mounting platform 32 is equipped with two fixed gears 64, located on the opposite side of the two flexible blocks 621. The fixed gears 64 are rotatably connected to the mounting platform 32 and located within the clearance holes 321. Each fixed gear 64 is engaged with a fixed rack 65, which is fixedly attached to the support rod 31 adjacent to the fixed gear 64. When the flexible box 61 is pressed against the pile, the flexible blocks 621 press against the fixed gears 64, forcing them into the tooth grooves of the fixed gears 64, thus restricting their rotation.

[0068] When the movable end of the first fixed oil cylinder 11 drives the flexible box 61 to press against the pipe pile to fix the first fixed ring 1, the hydraulic oil in the flexible box 61 can be squeezed to the middle 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 squeezed into the tooth groove of the fixed gear 64, making it difficult for the fixed gear 64 to rotate relative to the mounting slide 32. Since the fixed gear 64 is engaged with the fixed rack 65, the mounting slide 32 can be automatically fixed to the support rod 31.

[0069] Further, refer to Figure 3 A first spring 66 is provided in each of the two rod cavities of the double-headed oil cylinder 62. 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 movable end of the double-headed oil cylinder 62 to contract.

[0070] When it is necessary to release the restriction of the flexible block 621 on the fixed gear 64, the first fixed cylinder 11 is contracted, and the first spring 66 can drive the double-headed cylinder 62 to contract through the elastic force. The double-headed 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.

[0071] Specifically, refer to Figure 2 、 Figure 3 and Figure 4 The adjusting assembly 7 includes a first adjusting cylinder 71 , a first adjusting pipe 72 , a second adjusting cylinder 73 and a second adjusting pipe 74 .

[0072] Reference Figure 2 and Figure 4 The first adjustment cylinder 71 is fixedly connected to the mounting slide 32 where the welding gun 4 is located. The welding gun 4 is fixedly connected to the movable end of the first adjustment cylinder 71, and the rod cavity of the first adjustment cylinder 71 is connected to the atmosphere. One end of the first adjustment tube 72 is connected to the rodless cavity of the first adjustment cylinder 71, and the other end is connected to the rod cavities of all second fixed cylinders 21. The first adjustment tube 72 is used to allow the second fluid medium to flow between the rodless cavity of the first adjustment cylinder 71 and the rod cavities of the second fixed cylinders 21. The first adjustment cylinder 71 can adjust the position of the welding gun 4 under the control of the second fixed cylinders 21.

[0073] Reference Figure 2 and Figure 3 The second adjusting 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 adjusting cylinder 73, and the rod cavity of the second adjusting cylinder 73 is connected to the atmosphere. One end of the second adjusting tube 74 is connected to the rodless cavity of the second adjusting cylinder 73, and the other end is connected to the rod cavities of all the second fixed cylinders 21. The second adjusting tube 74 is used to allow a second fluid medium to flow between the rodless cavity of the second adjusting cylinder 73 and the rod cavity of the second fixed cylinder 21. The second fluid medium is hydraulic oil in this application. The second adjusting cylinder 73 can adjust the position of the cleaning grinding head 5 under the drive of the second fixed cylinder 21.

[0074] When the second fixed oil cylinder 21 is extended 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 gun 4 to move, and the second adjusting oil cylinder 73 drives the cleaning grinding head 5 to move, so that the welding gun 4 and the cleaning grinding head 5 can realize automatic adjustment of the welding working position under the drive of the second fixed oil cylinder 21.

[0075] Further, refer to Figure 3 and Figure 4 The adjustment assembly 7 further includes a second spring 75 and a third spring 76. The second spring 75 is disposed within the rod cavity of the first adjustment cylinder 71. One end of the second spring 75 is fixedly connected to the fixed end of the first adjustment cylinder 71, and the other end is fixedly connected to the movable end of the first adjustment cylinder 71. The second spring 75 is used to drive the first adjustment cylinder 71 to retract. The third spring 76 is disposed within the rod cavity of the second adjustment cylinder 73. One end of the third spring 76 is fixedly connected to the fixed end of the second adjustment cylinder 73, and the other end is fixedly connected to the movable end of the second adjustment cylinder 73. The third spring 76 is used to drive the second adjustment cylinder 73 to retract.

[0076] 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 accumulate elastic force.

[0082] Two second rotating shafts 821 are provided, each rotatably extending through the two support rods 31 of the mounting frame 3 on which the cleaning grinding head 5 is mounted. Two fourth gears 822 and two synchronous pulleys 823 are provided, each corresponding one-to-one with the second rotating shaft 821. The fourth gear 822 is fixedly connected to one end of the second rotating shaft 821, slidably disposed within the guide groove 811, and meshes with the ring gear 812. The synchronous pulley 823 is slidably mounted on the second rotating shaft 821. The second rotating shaft 821 is used to drive the synchronous pulley 823 to rotate.

A synchronous drive belt 825 is wound around the two synchronous pulleys 823 and the cleaning pulley 824.

[0083] When the two mounting frames 3 and the second fixed ring 2 rotate around the pipe pile, the fourth gear 822 can rotate under the drive of the ring gear 812, and the fourth gear 822 drives the second rotating shaft 821 to rotate, and the second rotating shaft 821 drives the synchronous pulley 823 to rotate, and the synchronous pulley 823 drives the synchronous drive belt 825 to rotate, and the synchronous drive belt 825 drives the cleaning pulley 824 to rotate, and the cleaning pulley 824 drives the cleaning grinding head 5 to rotate, so that the cleaning grinding head 5 can use the driving force generated by the rotation of the mounting frame 3 to automatically rotate when the welding gun 4 rotates for welding.

[0084] In particular, refer to Figure 3 A slider 8231 is fixedly connected to the synchronous pulley 823, and the slider 8231 is slidably set in the adjustment slot 8211 opened on the second rotating shaft 821.

The fourth spring 828 is used to drive the telescopic rod 827 to extend.

[0086] When the second adjusting cylinder 73 adjusts the position of the cleaning grinding head 5, the cleaning grinding head 5 can make the cleaning pulley 824 approach the pipe pile synchronously, and the cleaning pulley 824 can push the synchronous drive belt 825 close to the pipe pile. Since the circumference of the synchronous drive belt 825 is fixed, the synchronous drive belt 825 can pull the tensioning pulley 826 close to the pipe pile, and the tensioning pulley 826 drives the telescopic rod 827 to contract, so that the fourth spring 828 accumulates elastic force. Under the action of 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 easy to affect the adjustment of the position of the cleaning grinding head 5.
