Description

Technical Field

[0001] This utility model relates to the field of spiral drill pipe manufacturing technology, specifically to a welding device for low-guide-blade spiral drill pipes. Background Technology

[0002] The production of auger drill pipes involves the manufacture of multiple components or parts that need to be precisely joined together using welding techniques to form a complete drill pipe structure, ensuring a strong connection between the various parts of the drill pipe.

[0003] In existing technologies, when welding low-profile auger drill pipes, the auger blades are mostly sleeved on the drill pipe for welding. However, in this way, the auger blades are not effectively fixed, and the tightness and angle of the auger blades on the drill pipe cannot be adjusted. As a result, the weld surface cannot fit the drill pipe more tightly, and the weld strength cannot be effectively and stably guaranteed, thereby reducing the overall performance of the drill pipe. Utility Model Content

It solves the problem that in existing technologies, when welding low-guide-vane auger drill rods, the auger blades are mostly simply sleeved on the drill rod for welding. However, in this method, the auger blades are not effectively fixed, and the tightness and angle of the auger blades on the drill rod cannot be adjusted, resulting in the welding surface not being able to fit the drill rod more tightly, and thus the welding strength cannot be effectively and stably guaranteed.

[0012] Preferably, a worm gear is fixedly sleeved on the outer surface of the first rotating disk, and the worm gear is used to drive the first rotating disk and the blade clamping mechanism thereon to rotate. Two worm gear fixing plates are fixedly connected to the outer surface of the connecting frame.

[0013] Preferably, a worm is rotatably connected between the two worm fixing plates, and the worm meshes with a worm wheel. The worm and worm wheel are used to provide self-locking to ensure stability during welding. An adjusting motor is bolted to the outer surface of one worm fixing plate, and the output shaft of the adjusting motor is fixedly inserted into the worm.

[0014] Preferably, the blade clamping mechanism includes an inner groove ring, which is fixedly connected to the outer surface of the first rotating disk. A second rotating disk is rotatably connected inside the inner groove ring. The second rotating disk has a movable groove, and two clamping plates are rotatably connected inside the movable groove. Each of the two clamping plates has a pressure-bearing arc-shaped groove at the upper end of its opposite side.

[0015] Preferably, the upper surface of the second rotating disk is fixedly connected to two pin fixing plates, which are located on both sides of the movable groove. A pin is rotatably connected between the two pin fixing plates, and an elliptical cam is fixedly sleeved on the outer surface of the pin. Two protruding parts on the outer surface of the elliptical cam are adapted to two pressure arc grooves.

[0016] Preferably, each of the two clamping plates is fixedly connected to a tension spring fixing post at its upper end, and a tension spring is fixedly connected to the opposite side of each of the two tension spring fixing posts.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a welding device for low-profile auger drill pipes, which has the following advantages:

[0021] 1. The welding equipment for this low-guide-blade auger drill pipe uses two blade fixing and adjusting components to drive the two ends of the auger blade to rotate in opposite directions, allowing the auger blade to twist to a certain extent. Under the reverse control of the two adjusting motors, the auger blade can be twisted, loosened, and locked on the drill pipe, thus effectively adjusting the tightness of the auger blade on the drill pipe. Adjusting the tightness of the auger blade allows the weld surface to fit more tightly against the drill pipe, reducing welding defects such as porosity and slag inclusions, thereby greatly improving the welding strength. The increased welding strength means enhanced overall performance of the drill pipe. During drilling, the high-weld-strength drill pipe can withstand greater torque and tension, reducing downtime caused by drill pipe breakage or detachment, and improving drilling efficiency.

[0022] 2. The welding equipment for this low-profile auger drill pipe, through the simultaneous use of two blade fixing and adjusting components, can effectively control the angle position of the auger blades on the drill pipe. By precisely adjusting the angle of the auger blades, it can ensure that the drill pipe contacts the formation at the optimal angle during drilling, reducing frictional resistance caused by improper angles, thereby significantly improving drilling efficiency, enhancing the adaptability of the drill pipe to various drilling environments, and improving the adaptability and flexibility of the drill pipe.

[0023] 3. The welding equipment for this low-profile auger drill rod uses a blade clamping mechanism to fix both ends of the auger blades. Since the second rotating disk is rotatably connected within the inner groove ring, it rotates at the same angle as the inner groove ring until the blade clamping mechanism matches the tilt angle of the auger blades. This ensures that the auger blades accurately fit onto the drill rod, avoiding the problem of reduced welding accuracy due to misalignment and deformation. As a result, the welded auger drill rod has more accurate pitch and blade orientation, meeting design requirements. The stable pitch and blade orientation make the auger drill rod run more smoothly during drilling, reducing drilling interruptions and malfunctions caused by drill rod problems.

[0024] 4. The welding equipment for this low-profile auger drill pipe includes a bowl-shaped wire brush head positioned between the drill pipe and the auger blade in the drill pipe cleaning assembly. The bowl-shaped wire brush head fits into the gap between the drill pipe and the auger blade before welding, and also fits into the weld seam of the drill pipe and the auger blade after welding. This allows the bowl-shaped wire brush head to clean the weld seam before and after welding simultaneously. This avoids the problem of impurities and dust at the weld seam before welding affecting the welding quality and effect, and also allows for effective cleaning of iron filings generated by the cooling of the weld seam after welding. Operators can more easily observe the welding effect.

[0025] 5. The welding equipment for this low-blade auger drill pipe, through the waste collection box set in the drill pipe cleaning assembly, can collect the dust and iron filings cleaned by the cup-shaped wire brush head. This avoids the dust and iron filings generated during the welding process from affecting the aesthetics of the working environment and posing a potential threat to the health of operators. The waste collection box can effectively concentrate these impurities, reduce their scattering in the working area, and thus improve the working environment. Attached Figure Description

The worm 22 and the worm wheel 19 are used to provide self-locking to ensure stability during welding. An adjusting motor 23 is bolted to the outer surface of one worm fixing plate 20. The output shaft of the adjusting motor 23 is fixedly inserted into the worm 22.

Two clamping plates 11 are rotatably connected inside the movable groove 10. A pressure-bearing arc groove 12 is provided at the upper end of the opposite side of the two clamping plates 11.

[0045] Furthermore, two pin fixing plates 13 are fixedly connected to the upper surface of the second rotating disk 9. The two pin fixing plates 13 are located on both sides of the movable groove 10. A pin 14 is rotatably connected between the two pin fixing plates 13. An elliptical cam 15 is fixedly sleeved on the outer surface of the pin 14.

[0046] Furthermore, tension spring fixing posts 17 are fixedly connected to the upper ends of both clamping plates 11, and tension springs 18 are fixedly connected to the opposite sides of the two tension spring fixing posts 17.

[0047] For further details, please refer to Figure 1 , 2 and Figure 5 The drill pipe cleaning assembly includes a motor mounting base 26, which is fixedly connected to the upper surface of the movable frame 24. The movable frame 24 is provided with a waste collection box 28, which is used to collect waste.

[0048] Furthermore, a geared motor 27 is bolted to the motor mounting base 26. A bowl-shaped wire brush head 21 is fixedly sleeved on the outer surface of the output shaft of the geared motor 27. The bowl-shaped wire brush head 21 is located between the drill rod and the spiral blade. The bowl-shaped wire brush head fits into the gap between the drill rod and the spiral blade before welding. The bowl-shaped wire brush head also fits into the weld seam of the drill rod and the spiral blade after welding.

[0049] Furthermore, in use, the drill rod to be welded is installed between two pins 14, and then the helical blade is sleeved on the drill rod, with one end of the helical blade positioned between the two clamping plates 11. Then, by pressing the locking handle 16, the locking handle 16 can drive the elliptical cam 15 to rotate via the pins 14. When the elliptical cam 15 rotates, its protruding part can apply force to the two pressure-bearing arc-shaped grooves 12, causing the upper ends of the two clamping plates 11 to move away from each other, while the lower ends of the two clamping plates 11 move closer to each other, until the elliptical cam 15 rotates. When cam 15 rotates to its maximum radius, the lower ends of the two adjacent clamping plates 11 can clamp and fix the spiral blade. After the two blade fixing adjustment components are used to fix and clamp the two ends of the spiral blade, the starting of the adjustment motor 23 is controlled. The started adjustment motor 23 will drive the worm wheel 19 to rotate through the worm 22 on its output shaft. When the worm wheel 19 rotates, it drives the inner groove ring 8 on the first rotating disk 7 to rotate around the center of the convex fixed disk 6. Since the second rotating disk 9 is rotatably connected inside the inner groove ring 8, this can... The second rotating disk 9 rotates at the same angle as the inner grooved ring 8 until the blade clamping mechanism matches the tilt angle of the spiral blade. When the worm gear 19 drives the inner grooved ring 8 on the first rotating disk 7 to rotate around the center of the convex fixed disk 6, under the separate control of the two adjusting motors 23 on the two blade fixing adjusting components, the two blade fixing adjusting components drive the two ends of the spiral blade to rotate in opposite directions, so that the spiral blade can twist to a certain extent. Under the separate reverse control of the two adjusting motors 23, the spiral blade can be twisted, loosened, and locked on the drill rod, so that the tightness of the spiral blade on the drill rod can be effectively adjusted. Adjusting the tightness of the spiral blade can make the welding surface fit the drill rod more tightly, reduce welding defects such as porosity and slag inclusions, and thus greatly improve the welding strength. The improvement of welding strength means the enhancement of the overall performance of the drill rod. During drilling, the high welding strength drill rod can withstand greater torque and tension, reduce downtime caused by drill rod breakage or detachment, and improve drilling efficiency.

[0050] Furthermore, by using the two blade fixing and adjusting components together, the angle position of the helical blades on the drill pipe can be effectively controlled. By precisely adjusting the angle of the helical blades, it can be ensured that the drill pipe contacts the formation at the optimal angle during drilling, reducing frictional resistance caused by improper angles, thereby significantly improving drilling efficiency, enhancing the adaptability of the drill pipe to adapt to various drilling environments, and improving the adaptability and flexibility of the drill pipe.

[0051] Furthermore, the blade clamping mechanism secures both ends of the spiral blade. Since the second rotating disk 9 is rotatably connected within the inner groove ring 8, the second rotating disk 9 rotates at the same angle as the inner groove ring 8 until the blade clamping mechanism matches the tilt angle of the spiral blade. This allows the spiral blade to accurately fit onto the drill rod, avoiding the problem of reduced welding accuracy due to offset and deformation. As a result, the welded spiral drill rod is more accurate in pitch and blade orientation, meeting design requirements. The stable pitch and blade orientation make the spiral drill rod run more smoothly during drilling, reducing drilling interruptions and malfunctions caused by drill rod problems.

[0052] Furthermore, in the drill pipe cleaning assembly, the cup-shaped wire brush head 21 is positioned between the drill pipe and the spiral blade. The cup-shaped wire brush head fits into the gap between the drill pipe and the spiral blade before welding, and it also fits into the weld seam of the drill pipe and the spiral blade after welding. This allows the cup-shaped wire brush head 21 to clean the weld seam before and after welding simultaneously. This avoids the problem of impurities and dust at the weld seam before welding affecting the welding quality and effect, and also allows the iron filings generated by the cooling of the weld seam after welding to be effectively cleaned. Operators can more easily observe the welding effect.

[0053] Furthermore, the waste collection box 28 installed in the drill pipe cleaning assembly can collect the dust and iron filings cleaned by the cup-shaped wire brush head 21, avoiding the dust and iron filings generated during the welding process from affecting the aesthetics of the working environment and posing a potential threat to the health of operators. The waste collection box 28 can effectively concentrate these impurities, reduce their scattering in the working area, and thus improve the working environment.

[0054] Working principle: During use, the drill rod to be welded is installed between two pins 14, and then the spiral blade is fitted onto the drill rod, with one end of the blade positioned between two clamping plates 11. Pressing the locking handle 16 causes the locking handle 16 to rotate the elliptical cam 15 via the pins 14. When the elliptical cam 15 rotates, its protruding portion applies force to the two pressure-bearing arc-shaped grooves 12, causing the upper ends of the two clamping plates 11 to move away from each other while their lower ends move closer together, until the elliptical cam 15 rotates to its maximum radius. At this point, the lower ends of the two clamping plates 11 clamp and fix the spiral blade. After fixing and clamping both ends of the spiral blade using two blade fixing and adjusting components, the starting of the adjusting motor 23 drives the worm gear 19 to rotate via the worm 22 on its output shaft. When the worm gear 19 rotates... The worm gear 19 drives the inner groove ring 8 on the first rotating disk 7 to rotate around the center of the convex fixed disk 6. Since the second rotating disk 9 is rotatably connected inside the inner groove ring 8, the second rotating disk 9 can rotate around the rotation angle of the inner groove ring 8 until the blade clamping mechanism can match the tilt angle of the spiral blade. When the worm gear 19 drives the inner groove ring 8 on the first rotating disk 7 to rotate around the center of the convex fixed disk 6, under the separate control of the two adjusting motors 23 on the two blade fixing adjusting components, the two blade fixing adjusting components drive the two ends of the spiral blade to rotate in opposite directions, so that the spiral blade can be twisted to a certain extent. Under the separate reverse control of the two adjusting motors 23, the spiral blade can be twisted, loosened and locked on the drill rod, so that the tightness of the spiral blade on the drill rod can be effectively adjusted. Adjusting the tightness of the spiral blade can make the welding surface fit the drill rod more tightly.

[0055] Furthermore, by using the two blade fixing and adjusting components together, the angle position of the helical blade on the drill pipe can be effectively controlled. By precisely adjusting the angle of the helical blade, it can be ensured that the drill pipe contacts the formation at the optimal angle during drilling, reducing frictional resistance caused by improper angle.

[0056] Furthermore, the blade clamping mechanism fixes both ends of the spiral blade. Since the second rotating disk 9 is rotatably connected inside the inner groove ring 8, the second rotating disk 9 can rotate at the rotation angle of the inner groove ring 8 until the blade clamping mechanism can match the tilt angle of the spiral blade, so that the spiral blade can accurately fit on the drill rod, avoiding the problem of reduced welding accuracy caused by offset and deformation.

[0057] Furthermore, in the drill pipe cleaning assembly, the cup-shaped wire brush head 21 is positioned between the drill pipe and the spiral blade. The cup-shaped wire brush head fits into the gap between the drill pipe and the spiral blade before welding, and it also fits into the weld seam of the drill pipe and the spiral blade after welding. This allows the cup-shaped wire brush head 21 to clean the weld seam before and after welding simultaneously.

[0058] Furthermore, the waste collection box 28 installed in the drill pipe cleaning assembly can collect the dust and iron filings removed by the cup-shaped wire brush head 21.
