[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a welding device for a low-guide vane auger rod, which has the following beneficial effects:

[0021] 1. The low-guide-vane spiral drill pipe welding equipment drives the two ends of the spiral blade to rotate in opposite directions respectively through the two blade fixing and adjusting components, so that the spiral blade can be twisted to a certain extent. Under the reverse control of the two adjusting motors, the spiral blade can be twisted, loosened and locked on the drill pipe, so that the tightness of the spiral blade on the drill pipe can be effectively adjusted. By adjusting the tightness of the spiral blade, the welding surface can be more closely fitted to the drill pipe, and welding defects such as pores and slag inclusions can be reduced, thereby greatly improving the welding strength. The improvement of the welding strength means the enhancement of the overall performance of the drill pipe. During the drilling process, the drill pipe with high welding strength can withstand greater torque and tension, reduce the downtime caused by the breakage or falling off of the drill pipe, and improve the drilling efficiency.

[0022] 2. The low-guide vane spiral drill rod welding equipment can effectively control the angular position of the spiral blade on the drill rod by using two blade fixing adjustment components at the same time. By accurately adjusting the angle of the spiral blade, it can ensure that the drill rod contacts the formation at the optimal angle during the drilling process, reduce the friction resistance caused by improper angle, thereby significantly improving the drilling efficiency, enhancing the adaptability of the drill rod to adapt to various drilling environments, and improving the adaptability and flexibility of the drill rod.

[0023] 3.

In this way, the welded spiral drill rod is more accurate in pitch and blade direction, meeting the design requirements. The stable pitch and blade direction make the spiral drill rod smoother during the drilling process, reducing drilling interruptions and failures caused by drill rod problems.

[0024] 4. The low guide vane spiral drill rod welding equipment has a drill rod cleaning assembly in which a bowl-shaped wire brush head is located between the drill rod and the spiral blade. The bowl-shaped wire brush head fits with the gap between the drill rod and the spiral blade before welding, and the bowl-shaped wire brush head also fits with the weld between the drill rod and the spiral blade after welding. This enables the bowl-shaped wire brush head to clean the weld before and after welding at the same time, thereby avoiding the problem of impurities and dust in the weld before welding affecting the welding quality and effect, and also enables the iron filings generated by cooling of the weld after welding to be effectively cleaned, so that the operator can observe the welding effect more easily.

[0025] 5. The low-guide-vane spiral drill rod welding equipment can collect dust and iron filings cleaned by the bowl-shaped wire brush head through the waste collection box arranged in the drill rod cleaning assembly, thereby preventing 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 the operators.

[0047] For further information, see Figure 1 , 2 and Figure 5 The drill rod cleaning assembly includes a motor fixing seat 26, which is fixedly connected to the upper surface of the mobile frame 24. The mobile frame 24 is provided with a waste collection box 28, which is used to receive and collect waste.

[0048] Furthermore, a reduction motor 27 is bolted fixedly connected to the motor fixing seat 26, and a bowl-shaped wire brush head 21 is fixedly sleeved on the outer surface of the output shaft of the reduction 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 in the gap between the drill rod and the spiral blade before welding, and the bowl-shaped wire brush head also fits in the weld between the drill rod and the spiral blade after welding.

[0049] Furthermore, when in use, the drill rod to be welded is installed between the two pins 14, and then the spiral blade is sleeved on the drill rod so that one end of the spiral blade is located between the two clamping plates 11, and then the locking handle 16 is pressed, and the locking handle 16 can drive the elliptical cam 15 to rotate through the pin 14. When the elliptical cam 15 rotates, the raised portion on it can exert a force on the two compressed arc grooves 12, so that the upper ends of the two clamping plates 11 are separated from each other, and the lower ends of the two clamping plates 11 are close to each other until the elliptical cam 15 rotates. The cam 15 rotates to its maximum radius, at which time the lower ends of the two clamping plates 11 approaching each other can clamp the spiral blades firmly. After the two ends of the spiral blades are clamped firmly by using the two blade fixing and adjusting components, the start of the adjusting motor 23 is controlled. The started adjusting motor 23 drives the worm gear 19 to rotate through the worm 22 on its output shaft. When the worm gear 19 rotates, it drives the inner groove ring 8 on the first rotating disk 7 to rotate about the center of the convex fixed disk 6. Since the second rotating disk 9 is connected to the inner groove ring 8 by rotation, this can The second rotating disk 9 will rotate at the rotation angle of the inner groove ring 8 until the blade clamping mechanism can adapt to the inclination angle of the spiral blade. When the worm gear 19 drives the inner groove ring 8 on the first rotating disk 7 to rotate about the center of the convex fixed disk 6, under the separate control of the two adjusting motors 23 on the two blade fixing adjustment components, the two blade fixing adjustment components respectively 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. By adjusting the tightness of the spiral blade, the welding surface can be more closely fitted to the drill rod, reducing welding defects such as pores and slag inclusions, thereby greatly improving the welding strength. The improvement of welding strength means the enhancement of the overall performance of the drill rod. During the drilling process, the drill rod with high welding strength can withstand greater torque and tension, reduce downtime caused by drill rod breakage or falling off, and improve drilling efficiency.

[0050] Furthermore, by using the two blade fixing adjustment components at the same time, the angular position of the spiral blade on the drill rod can be effectively controlled. By accurately adjusting the angle of the spiral blade, it can be ensured that the drill rod contacts the formation at the optimal angle during the drilling process, reducing the friction resistance caused by improper angles, thereby significantly improving the drilling efficiency, enhancing the adaptability of the drill rod to adapt to various drilling environments, and improving the adaptability and flexibility of the drill rod.

[0051] Furthermore, the two ends of the spiral blade are fixed by a blade clamping mechanism, wherein since the second rotating disk 9 is rotatably connected in 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 adapt to the inclination angle of the spiral blade, so that the spiral blade can fit accurately on the drill rod, avoiding the problem of reduced welding accuracy due to offset and deformation. In this way, the welded spiral drill rod is more accurate in pitch and blade direction, meeting the design requirements. The stable pitch and blade direction make the spiral drill rod smoother during the drilling process, reducing drilling interruptions and failures caused by drill rod problems.

[0052] Furthermore, in the drill rod cleaning assembly, the bowl-shaped wire brush head 21 is located between the drill rod and the spiral blade. The bowl-shaped wire brush head fits with the gap between the drill rod and the spiral blade before welding, and the bowl-shaped wire brush head also fits with the weld between the drill rod and the spiral blade after welding. This enables the bowl-shaped wire brush head 21 to clean the welds before and after welding at the same time, thereby avoiding the problem of impurities and dust in the welds before welding affecting the welding quality and effect, and also enables the iron filings generated by cooling of the welds after welding to be effectively cleaned, and the operator can observe the welding effect more easily.

[0053] Furthermore, the waste collection box 28 provided in the drill rod cleaning assembly can collect the dust and iron filings cleaned by the bowl-shaped wire brush head 21, thereby preventing 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 the operators. The waste collection box 28 can effectively concentrate these impurities and reduce their scattering in the working area, thereby improving the working environment.

[0054] Working principle: When in use, the drill rod to be welded is installed between the two pins 14, and then the spiral blade is sleeved on the drill rod so that one end of the spiral blade is located between the two clamping plates 11, and then the locking handle 16 is pressed. The locking handle 16 can drive the elliptical cam 15 to rotate through the pin 14. When the elliptical cam 15 rotates, the raised part thereof can exert a force on the two compressed arc grooves 12, so that the upper ends of the two clamping plates 11 are separated from each other, and at the same time, the lower ends of the two clamping plates 11 are close to each other until the elliptical cam 15 rotates to its maximum radius. At this time, the lower ends of the two clamping plates 11 close to each other can clamp the spiral blade to fix it. After using two blade fixing adjustment components to fix the two ends of the spiral blade, by controlling the start of the adjustment motor 23, the started adjustment motor 23 will drive the worm gear 19 to rotate through the worm 22 on its output shaft. When the worm gear 19 rotates The inner groove ring 8 on the first rotating disk 7 is driven to rotate about the center of the convex fixed disk 6. Since the second rotating disk 9 is rotatably connected in 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 adapt to the inclination angle of the spiral blade. When the worm gear 19 drives the inner groove ring 8 on the first rotating disk 7 to rotate about 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 respectively 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. By adjusting the tightness of the spiral blade, the welding surface can fit the drill rod more closely.

[0055] Furthermore, by using two blade fixing adjustment components at the same time, the angular position of the spiral blade on the drill pipe can be effectively controlled. By accurately adjusting the angle of the spiral blade, it can be ensured that the drill pipe contacts the formation at the optimal angle during the drilling process, thereby reducing the friction resistance caused by improper angles.

[0056] Furthermore, the two ends of the spiral blade are fixed by a blade clamping mechanism, wherein since the second rotating disk 9 is rotatably connected in 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 adapt to the inclination angle of the spiral blade, so that the spiral blade can fit accurately on the drill rod, avoiding the problem of reduced welding accuracy due to offset and deformation.

[0057] Furthermore, in the drill rod cleaning assembly, the bowl-shaped wire brush head 21 is located between the drill rod and the spiral blade. The bowl-shaped wire brush head fits with the gap between the drill rod and the spiral blade before welding. The bowl-shaped wire brush head also fits with the weld between the drill rod and the spiral blade after welding. This enables the bowl-shaped wire brush head 21 to clean the welds before and after welding at the same time.

[0058] Furthermore, the waste collection box 28 provided in the drill rod cleaning assembly can collect the dust and iron filings impurities cleaned by the bowl-shaped wire brush head 21 .
