Technical Field

[0001] The present invention relates to the technical field of welded pipe machines, and particularly relates to a high-frequency straight seam welded pipe machine for acoustic pipes. Background Art

[0002] Acoustic pipes can detect the quality of a pile using sound waves. An acoustic pipe is a channel for a probe to enter the interior of a pile during ultrasonic testing of a cast-in-place pile. It is an important part of the ultrasonic testing system for cast-in-place piles. The embedding method in the pile and its layout form on the cross-section of the pile will directly affect the test results. Therefore, for the piles to be tested, the layout and embedding method of the acoustic pipes should be marked on the drawings during design, and the quality of embedding and the thickness of the pipe wall should be strictly controlled during construction to ensure the smooth progress of the testing work.

[0008] Preferably, tension springs are movably sleeved on the surfaces of the two first limiting rods. One end of each of the two tension springs, which faces the other, is fixedly connected to the inside of the moving seat, and the other end of each of the two tension springs, which faces away from the other, is fixedly connected to one of the two moving frames respectively.

[0009] Preferably, toothed plates are fixedly installed on one side of each of the two moving frames, which faces the other. A gear is rotatably connected to the inside of the moving seat. The two toothed plates are both meshed with the surface of the gear. Through grooves matching the toothed plates are formed in each of the two moving frames, and the two toothed plates are adapted to the two through grooves.

[0010] Preferably, the moving frame near the second motor slides through the moving seat and extends to the bottom of the moving seat. The moving frame away from the second motor is located inside the moving seat. A blocking block is fixedly installed inside the workbench.

[0011] Preferably, a rotating plate is rotatably connected to one side of each of the two moving frames, which faces the other.

[0012] Preferably, a pressing slide rod is slidably connected to the inside of the moving seat. A lifting push plate is fixedly installed at the upper end of the pressing slide rod. The lifting push plate is located inside the moving seat.

[0013] Preferably, a slideway is formed inside the moving seat. A lifting block is slidably connected to the inside of the slideway. The lifting block is fixedly connected to the surface of the pressing slide rod.

[0014] Preferably, a second limiting rod is fixedly installed inside the slideway. The surface of the second limiting rod is slidably connected to the inside of the lifting block.

[0015] Preferably, a rotating wheel is rotatably connected to the inside of the pressing slide rod. A right trapezoidal convex block is fixedly installed inside the workbench. The shape of the right trapezoidal convex block is inclined. The right trapezoidal convex block and the pressing slide rod are on the same straight line. The moving frame and the blocking block are on the same straight line. The pressing slide rod and the moving frame are not on the same straight line.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1). For this ultrasonic testing tube high-frequency straight seam welding machine, two ultrasonic testing tubes to be welded are placed into two chambers inside the storage bin. The ultrasonic testing tubes to be welded enter into the two grooves, and then the first motor is started, which drives two rotating rollers to rotate. As a result, the ultrasonic testing tubes rotate along with the rotating rollers. When the two rotating rollers flip 180 degrees, the ultrasonic testing tubes will fall off, which is convenient for automatic feeding, improves the convenience of feeding the ultrasonic testing tubes, and reduces the working intensity of the staff.

[0017] (2). For this ultrasonic testing tube high-frequency straight seam welding machine, the extrusion slide rod and the rotating wheel move upward, so that the lifting block slides on the surfaces of the slideway and the second limiting rod, and then squeezes the elastic spring. When the extrusion slide rod moves upward, the lifting push plate will move upward along with the extrusion slide rod, and then push the ultrasonic testing tube inside the moving seat out of the moving seat, which is convenient for pushing the welded ultrasonic testing tube out of the moving seat and convenient for taking the ultrasonic testing tube.

[0018] (3). For this ultrasonic testing tube high-frequency straight seam welding machine, the moving seat gradually resets. When one side of the moving frame contacts the blocking block, the moving frame will be blocked by the blocking block and thus unable to move. Then the moving frame slides inside the moving seat and on the first limiting rod, and drives the other moving frame to move through two toothed plates and a gear, so that the two moving frames move away from each other, stretching two tension springs, which is convenient for the next use of the device and improves the convenience of later use.

[0019] (4). For this ultrasonic testing tube high-frequency straight seam welding machine, the third motor is started to drive one of the rotating plates to rotate. Since the two ultrasonic testing tubes are squeezed by the two rotating plates, they are driven to rotate, which is convenient for moving into the area of the welding machine body for welding, convenient for rotating to weld the ultrasonic testing tubes, improves the convenience of welding the ultrasonic testing tubes, is convenient for automatic welding, reduces manual intervention, and can achieve straight seam welding at the same time, improving the diversification of the welding forms of the device.

[0020] (5). For this ultrasonic testing tube high-frequency straight seam welding machine, the moving frame is no longer blocked by the blocking block, so that one side of the moving frame resets under the tension of the tension spring and slides on the surface of the moving seat and the first limiting rod. Then it drives the other moving frame to move through two toothed plates and a gear, so that the two moving frames move relatively, and the two rotating plates clamp the two ultrasonic testing tubes, which is convenient for clamping the ultrasonic testing tubes, preventing the ultrasonic testing tubes from moving during welding, and improving the stability of welding.

[0021] (6) For this ultrasonic testing tube high-frequency straight seam welding machine, start the second motor to drive the threaded rod to rotate, so that the moving seat moves inside the workbench and slides on the fixed rod and the chute. Through the settings of the fixed rod and the chute, it is convenient to limit the moving seat, ensuring the smooth movement of the moving seat, preventing the moving seat from shaking, improving the stability of the moving seat during use, and thus facilitating the welding of the ultrasonic testing tube.

Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0026] Please refer to Figures 1-9 , the present invention provides a technical solution: a high-frequency straight-seam welding machine for acoustic pipes, including a workbench 1. A welding machine body 4 is arranged on the top of the workbench 1. A storage bin 5 is fixedly installed on the top of the workbench 1. A first motor 6 is fixedly installed on one side of the storage bin 5. The output end of the first motor 6 rotates through the storage bin 5 and extends into the interior of the storage bin 5. A rotating roller 8 is fixedly installed at the output end of the first motor 6. The rotating roller 8 is rotatably connected inside the storage bin 5. Grooves 9 are formed on the surface of the rotating roller 8. Put the two acoustic pipes to be welded into the two chambers inside the storage bin 5. The acoustic pipes to be welded enter into the two grooves 9. Then start the first motor 6 to drive the two rotating rollers 8 to rotate, so that the acoustic pipes rotate with the rotating rollers 8. Then when the two rotating rollers 8 turn 180 degrees, the acoustic pipes will fall off, which is convenient for automatic feeding, improves the convenience of feeding the acoustic pipes, and reduces the working strength of the staff. A second motor 10 is fixedly installed on one side of the workbench 1. The output end of the second motor 10 rotates through the workbench 1 and extends into the interior of the workbench 1. A threaded rod 12 is fixedly installed at the output end of the second motor 10. A moving seat 7 is threadedly connected to the surface of the threaded rod 12. A sliding groove 3 is formed inside the workbench 1. A fixed rod 2 is fixedly installed inside the sliding groove 3. The moving seat 7 slides inside the sliding groove 3 and on the surface of the fixed rod 2. Start the second motor 10 to drive the threaded rod 12 to rotate, so that the moving seat 7 moves inside the workbench 1 and slides on the fixed rod 2 and the sliding groove 3. Then through the settings of the fixed rod 2 and the sliding groove 3, it is convenient to limit the moving seat 7, ensure the smooth movement of the moving seat 7, prevent the moving seat 7 from shaking, improve the stability of the moving seat 7 in use, and facilitate the welding of the acoustic pipes. There are two moving frames 14 slidably connected inside the moving seat 7. Two first limiting rods 23 are fixedly installed inside the moving seat 7. The surfaces of the two first limiting rods 23 are respectively slidably connected to the inside of the two moving frames 14. Tension springs 17 are movably sleeved on the surfaces of the two first limiting rods 23. One end of the two tension springs 17 facing each other is fixedly connected to the inside of the moving seat 7, and the other end of the two tension springs 17 facing away from each other is respectively fixedly connected to the two moving frames 14. Tooth plates 21 are fixedly installed on one side of the two moving frames 14 facing each other. A gear 22 is rotatably connected inside the moving seat 7. The two tooth plates 21 are both meshed with the surface of the gear 22. Through grooves matching the tooth plates 21 are formed on the two moving frames 14. The two tooth plates 21 are adapted to the two through grooves. The moving frame 14 near the second motor 10 slides through the moving seat 7 and extends to the bottom of the moving seat 7. The moving frame 14 on the side away from the second motor 10 is located inside the moving seat 7. A blocking block 11 is fixedly installed inside the workbench 1. Rotating plates 18 are rotatably connected to one side of the two moving frames 14 facing each other. A third motor 15 is fixedly installed on one side of one of the moving frames 14. The output end of the third motor 15 rotates through the moving frame 14 and is fixedly connected to one of the rotating plates 18. After the acoustic pipe is discharged from the inside of the storage tank 5, it will enter the inside of the moving seat 7 and between the two rotating plates 18, thereby causing the moving seat 7 to move to one side, so that the moving frame 14 is no longer blocked by the blocking block 11, so that one side of the moving frame 14 is reset by the tension of the tension spring 17 and slides on the surface of the first limiting rod 23 inside the moving seat 7. Then, the other moving frame 14 is driven to move through the two tooth plates 21 and one gear 22, so that the two moving frames 14 move relatively, and the two rotating plates 18 clamp the two acoustic pipes, which is convenient for clamping the acoustic pipes and preventing the acoustic pipes from moving during welding, improving the stability of welding. Start the third motor 15 to drive one of the rotating plates 18 to rotate. Then, due to the two acoustic pipes being squeezed by the two rotating plates 18, the acoustic pipes are driven to rotate, which is convenient for moving into the area of the welding machine body 4 for welding, and is convenient for rotating to weld the acoustic pipes, improving the convenience of welding the acoustic pipes, facilitating automatic welding, reducing manual intervention, and at the same time, straight seam welding can be realized, improving the diversification of the welding forms of the device. Since through grooves are formed on the two moving frames 14, when the two tooth plates 21 move relatively, the two tooth plates 21 will respectively pass through the through grooves on the two moving frames 14, thereby preventing the two tooth plates 21 from being blocked by the two moving frames 14, resulting in the inability of the two moving frames 14 to move relatively, facilitating the relative movement of the two moving frames 14 and making the moving distance of the two moving frames 14 larger. Start the second motor 10, causing the second motor 10 to drive the threaded rod 12 to rotate in the reverse direction, thereby gradually resetting the moving seat 7. When the moving frame 14 on one side contacts the blocking block 11, the moving frame 14 will be blocked by the blocking block 11, so that the moving frame 14 cannot move. Then, the moving frame 14 slides inside the moving seat 7 and on the first limiting rod 23. Then, through two toothed plates 21 and a gear 22, the other moving frame 14 is driven to move, so that the two moving frames 14 move away from each other, stretching the two tension springs 17, which is convenient for the next use of the device and improves the convenience of later use. A pressing slide rod 19 is slidably connected inside the moving seat 7. The upper end of the pressing slide rod 19 is fixedly installed with a lifting push plate 16. The lifting push plate 16 is located inside the moving seat 7. A slideway 24 is opened inside the moving seat 7. A lifting block 27 is slidably connected inside the slideway 24. The lifting block 27 is fixedly connected to the surface of the pressing slide rod 19. A second limiting rod 25 is fixedly installed inside the slideway 24. The surface of the second limiting rod 25 is slidably connected to the inside of the lifting block 27. A elastic spring 26 is movably sleeved on the surface of the second limiting rod 25. The upper end of the elastic spring 26 is fixedly connected to the inner wall of the slideway 24. The lower end of the elastic spring 26 is fixedly connected to the surface of the lifting block 27. A rotating wheel 20 is rotatably connected inside the pressing slide rod 19. A right trapezoidal convex block 13 is fixedly installed inside the workbench 1. The shape of the right trapezoidal convex block 13 is inclined. The right trapezoidal convex block 13 and the pressing slide rod 19 are on the same straight line. The moving frame 14 and the blocking block 11 are on the same straight line. The pressing slide rod 19 and the moving frame 14 are not on the same straight line. After welding is completed, the second motor 10 will drive the moving seat 7 to continue moving to one side. Then, the rotating wheel 20 will contact the right trapezoidal convex block 13 and slide along the inclined surface of the right trapezoidal convex block 13, so that the pressing slide rod 19 and the rotating wheel 20 move upward. Then, the lifting block 27 slides on the surface of the slideway 24 and the second limiting rod 25, thereby squeezing the elastic spring 26. When the pressing slide rod 19 moves upward, the lifting push plate 16 will move upward following the pressing slide rod 19, thereby pushing the sound measuring tube inside the moving seat 7 out of the moving seat 7, which is convenient for pushing the welded sound measuring tube out of the moving seat 7 and convenient for taking the sound measuring tube.

[0027] Working principle: Put the two sound measuring tubes to be welded into the two chambers inside the storage box 5. The sound measuring tubes to be welded enter the two grooves 9. Then, start the first motor 6, causing the first motor 6 to drive the two rotating rollers 8 to rotate. Then, the sound measuring tubes rotate following the rotating rollers 8. Then, when the two rotating rollers 8 rotate 180 degrees, the sound measuring tubes will fall off, which is convenient for automatic feeding.

[0028] Start the second motor 10 to drive the threaded rod 12 to rotate, thereby causing the moving seat 7 to move inside the workbench 1. After the sound detection tube is discharged from the inside of the storage bin 5, it will enter the inside of the moving seat 7 and between the two rotating plates 18, thereby causing the moving seat 7 to move to one side, so that the moving frame 14 is no longer blocked by the blocking block 11. Then, one side of the moving frame 14 is reset by the pulling force of the tension spring 17 and slides on the surface of the first limiting rod 23 inside the moving seat 7. Then, the two toothed plates 21 and a gear 22 drive the other moving frame 14 to move, so that the two moving frames 14 move relatively, and the two rotating plates 18 clamp the two sound detection tubes.

[0029] Start the third motor 15 to drive one of the rotating plates 18 to rotate. Then, because the two sound detection tubes are squeezed by the two rotating plates 18, the sound detection tubes are driven to rotate, which is convenient for moving into the area of the welding machine body 4 for welding, and is convenient for rotating to weld the sound detection tubes.

[0030] Start the second motor 10 to drive the threaded rod 12 to rotate in the reverse direction, thereby causing the moving seat 7 to gradually reset. When one side of the moving frame 14 contacts the blocking block 11, the moving frame 14 will be blocked by the blocking block 11, so that the moving frame 14 cannot move. Then, the moving frame 14 slides on the first limiting rod 23 inside the moving seat 7. Then, the two toothed plates 21 and a gear 22 drive the other moving frame 14 to move, so that the two moving frames 14 move away from each other.

[0031] After welding is completed, the second motor 10 will drive the moving seat 7 to continue moving to one side. Then, the rotating wheel 20 will contact the right-angled trapezoidal convex block 13 and slide along the inclined surface of the right-angled trapezoidal convex block 13, so that the extrusion slide rod 19 and the rotating wheel 20 move upward. Then, the lifting block 27 slides on the surface of the slideway 24 and the second limiting rod 25, thereby squeezing the elastic spring 26. When the extrusion slide rod 19 moves upward, the lifting push plate 16 will move upward following the extrusion slide rod 19, thereby pushing the sound detection tube inside the moving seat 7 out of the inside of the moving seat 7, which is convenient for pushing the welded sound detection tube out of the inside of the moving seat 7.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
