Description

Technical Field

[0001] This utility model relates to the field of pipeline welding inspection technology, and in particular to a pipeline welding inspection device for wastewater treatment equipment. Background Technology

[0002] Wastewater treatment equipment plays a vital role in modern environmental protection and industrial production. Its main function is to purify and treat industrial wastewater and domestic sewage. In the design and construction of wastewater treatment facilities, pipeline welding technology is one of the keys to ensuring the long-term stable operation of the equipment. Because the pipelines may be subjected to harsh conditions such as high corrosion, high pressure, and high temperature during the wastewater treatment process, the welding quality of the pipelines is directly related to the safety and reliability of the system. Therefore, efficient and accurate testing of the welding quality of wastewater treatment equipment pipelines is an important link to ensure the long-term stable operation of the equipment.

[0003] Traditional pipeline welding inspection devices often employ fixed chucks or manual adjustment mechanisms, which are ill-suited for automatic centering of pipes of varying lengths. This results in low clamping efficiency and workpiece deformation due to uneven stress, frequently leading to eccentric clamping and affecting inspection accuracy. Furthermore, angle adjustment relies on manual experience and lacks a precision transmission system, making it difficult to guarantee consistent and repeatable weld tracking. Frequent machine shutdowns for tooling changes are also necessary when dealing with pipes of varying diameters, severely limiting production efficiency and failing to meet the demands of modern wastewater treatment systems for efficient, intelligent, and flexible inspection. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pipe welding inspection device for wastewater treatment equipment.

[0005] This utility model is achieved using the following technical solution: a pipe welding inspection device for wastewater treatment equipment, comprising a fixed base, wherein a sliding groove is provided inside the fixed base, a connecting frame is fixedly connected to the top of the fixed base, and a reserved groove is provided inside the connecting frame, and further comprising: A fixing mechanism, comprising a sliding block slidably connected inside a sliding groove, a fixing frame slidably connected inside the sliding block, and a clamping block fixedly connected outside the fixing frame; An adjustment mechanism includes a support frame fixedly connected to the top of the connecting frame, a connecting block is provided inside the support frame, and a laser weld seam tracker is fixedly connected to the bottom of the connecting block.

[0006] As a further improvement to the above solution, a hydraulic rod is fixedly connected to the right side of the fixed base, the sliding block is fixedly connected to the left end of the hydraulic rod, and a bidirectional threaded rod is rotatably connected inside the sliding block.

[0007] The above technical solution enables rapid adjustment of the testing station and pipes of different lengths by setting a hydraulic rod to drive the sliding block to move axially along the sliding groove of the fixed base. This hydraulic propulsion method is more labor-saving and efficient than manual adjustment, and the stroke is highly controllable, laying the foundation for subsequent multi-specification adaptation.

[0008] As a further improvement to the above solution, the fixing bracket is threaded to the outside of the bidirectional threaded rod, and two fixing brackets are provided, each threaded to the outside of the bidirectional threaded rod in a different thread direction.

[0009] The above technical solution uses a bidirectional threaded rod in conjunction with two opposing rotating fixing frames, which allows the single drive shaft to synchronously drive the clamping blocks on both sides to move in opposite directions or away from each other when rotating. This design ensures the symmetrical distribution of clamping force, avoids the off-center load problem caused by traditional single-sided drive, and significantly improves clamping stability and coaxiality accuracy.

[0010] As a further improvement to the above solution, a drive motor is fixedly connected to the right side of the fixed base, a convex shaft is fixedly connected to the output end of the drive motor, a sliding sleeve is slidably connected to the outside of the convex shaft, and the sliding sleeve is rotatably connected inside the sliding block.

[0011] As a further improvement to the above solution, a first bevel gear is fixedly connected to the outside of the sliding sleeve, and a second bevel gear is fixedly connected to the outside of the bidirectional threaded rod, with the second bevel gear meshing with the first bevel gear.

[0012] As a further improvement to the above solution, a transmission housing is fixedly connected to the front of the support frame, a servo motor is fixedly connected to the right side of the transmission housing, and a worm gear is fixedly connected to the output end of the servo motor.

[0013] By integrating a servo motor and a direct-drive worm gear onto the support frame, and utilizing its high speed ratio characteristics to achieve precise angle fine-tuning, positioning errors can be reduced, thus meeting the requirements for high-precision weld seam tracking.

[0014] As a further improvement to the above solution, the worm gear is rotatably connected inside the transmission housing, a transmission column is rotatably connected inside the support frame, and a worm wheel is fixedly connected to the outside of the transmission column.

[0015] The above technical solution uses a worm gear and worm wheel as the main transmission mechanism, which leverages its self-locking characteristics to prevent accidental retraction. Combined with a transmission column supported by a deep groove ball bearing, it can both bear radial loads and reduce frictional losses, extending mechanical life while maintaining smooth movement.

[0016] As a further improvement to the above solution, the worm gear meshes with the worm, and the connecting block is fixedly connected to the outside of the transmission column.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the coordinated operation of an adaptive telescopic and synchronous clamping structure composed of a hydraulic rod, sliding block, sliding sleeve, convex shaft, first bevel gear, second bevel gear, bidirectional threaded rod, fixing frame, and clamping block. This structure enables precise centering and uniform radial pressure application to pipes of different lengths and diameters, thereby achieving rapid and stable fixing of pipes of various specifications. The mechanism uses bevel gear pairs to ensure synchronous movement of the sliding units on both sides, and the bidirectional threaded rod converts rotational motion into opposing linear displacement, ensuring that the clamping block always closes symmetrically along the pipe axis. This effectively avoids eccentric clamping problems caused by pipe diameter deviations and ensures the accuracy of the detection benchmark.

[0018] This invention utilizes the coordinated operation of a precision angle adjustment system comprised of a servo motor, worm gear, worm wheel, transmission column, connecting block, and laser weld seam tracker to enable controllable adjustment of the laser weld seam tracker's angle. This allows for full-circumferential scanning and dynamic tracking detection of circumferential weld seams without blind spots. The high reduction ratio of the worm gear and worm wheel transmission, combined with the closed-loop control of the servo motor, improves angle positioning accuracy. This, in turn, enables the laser weld seam tracker to meet the adaptive detection requirements of complex curved weld seams, significantly improving defect identification coverage.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example: Please combine Figure 1-6 This embodiment of a pipe welding inspection device for wastewater treatment equipment includes a fixed base 1, with a sliding groove 11 inside the fixed base 1, and a connecting frame 12 fixedly connected to the top of the fixed base 1. The connecting frame 12 has a reserved groove 13 inside, and also includes: The fixing mechanism 2 includes a sliding block 202 that is slidably connected inside the sliding groove 11, a fixing frame 204 that is slidably connected inside the sliding block 202, and a clamping block 205 that is fixedly connected outside the fixing frame 204. Adjustment mechanism 3 includes a support frame 301 fixedly connected to the top of the connecting frame 12. A connecting block 307 is provided inside the support frame 301. A laser weld seam tracker 308 is fixedly connected to the bottom of the connecting block 307.

[0023] A hydraulic rod 201 is fixedly connected to the right side of the fixed base 1, and a sliding block 202 is fixedly connected to the left end of the hydraulic rod 201. A bidirectional threaded rod 203 is rotatably connected inside the sliding block 202.

[0024] The fixing bracket 204 is threaded to the outside of the bidirectional threaded rod 203. There are two fixing brackets 204, which are threaded to the outside of the bidirectional threaded rod 203 in different thread directions.

[0025] A drive motor 206 is fixedly connected to the right side of the fixed base 1. A convex shaft 207 is fixedly connected to the output end of the drive motor 206. A sliding sleeve 208 is slidably connected to the outside of the convex shaft 207. The sliding sleeve 208 is rotatably connected inside the sliding block 202.

[0026] The hydraulic rod 201 extends, which can drive the sliding block 202 to slide inside the sliding groove 11, thereby adjusting the distance between the sliding blocks 202 to adapt to pipes of different lengths for inspection. When the sliding block 202 moves, it will drive the sliding sleeve 208 rotatably connected inside it to slide outside the convex shaft 207, thereby maintaining the meshing of the first bevel gear 209 and the second bevel gear 2010.

[0027] The sliding sleeve 208 is externally fixedly connected to a first bevel gear 209, and the bidirectional threaded rod 203 is externally fixedly connected to a second bevel gear 2010, which meshes with the first bevel gear 209.

[0028] The drive motor 206 is started to drive the cam shaft 207 to rotate, which in turn drives the sliding sleeve 208 to rotate. This causes the sliding sleeve 208 to drive the first bevel gear 209 outside it to rotate synchronously, which in turn drives the second bevel gear 2010 to rotate. This causes the bidirectional threaded rod 203 inside the sliding block 202 to rotate. As the bidirectional threaded rod 203 rotates, the fixing brackets 204 will move closer to each other and clamp the pipe.

[0029] A transmission housing 302 is fixedly connected to the front of the support frame 301, a servo motor 303 is fixedly connected to the right side of the transmission housing 302, and a worm gear 304 is fixedly connected to the output end of the servo motor 303.

[0030] The worm gear 304 is rotatably connected inside the transmission housing 302, and the transmission column 305 is rotatably connected inside the support frame 301. The worm wheel 306 is fixedly connected to the outside of the transmission column 305.

[0031] The worm gear 306 meshes with the worm 304, and the connecting block 307 is fixedly connected to the outside of the transmission column 305.

[0032] The servo motor 303 is started to drive the worm gear 304 to rotate, which in turn drives the worm wheel 306 to rotate, thereby driving the transmission column 305 inside to rotate. As the clamping block 205 rotates, the connecting block 307 connected to it rotates accordingly, ultimately driving the laser weld seam tracker 308 to rotate.

[0033] The implementation principle of the pipeline welding inspection device for wastewater treatment equipment in this embodiment is as follows: During use, the hydraulic rod 201 can be extended according to the length of the pipeline, causing the sliding block 202 to slide inside the sliding groove 11, thereby adjusting the distance between the sliding blocks 202. This allows for inspection of pipelines of different lengths. When the sliding block 202 moves, it causes the sliding sleeve 208, which is rotatably connected inside, to slide outside the convex shaft 207, thus maintaining the meshing of the first bevel gear 209 and the second bevel gear 2010. After adjusting the distance of the sliding blocks 202, the drive motor 206 can be started to drive the convex shaft 207 to the fixed base 1. The internal rotation of the sliding block 202 causes the external sliding sleeve 208 to rotate inside the sliding block 202. This causes the sliding sleeve 208 to drive the external first bevel gear 209 to rotate synchronously. Due to the meshing of the first bevel gear 209 and the second bevel gear 2010, when the first bevel gear 209 rotates, it will drive the second bevel gear 2010 to rotate as well. This causes the internal bidirectional threaded rod 203 to rotate inside the sliding block 202. As the bidirectional threaded rod 203 rotates, the fixing brackets 204, which are threaded to the outside of the bidirectional threaded rod 203 in different thread directions, will move closer to each other, thereby driving the clamping block 205 to clamp the pipe and complete the fixation. After fixing is completed, the servo motor 303 can be started to drive the worm 304 to rotate inside the transmission housing 302 according to the required inspection angle. Since the worm 304 and the worm wheel 306 mesh with each other, when the worm 304 rotates, it can drive the worm wheel 306 to rotate, thereby driving the transmission column 305 inside to rotate. As the clamping block 205 rotates, the connecting block 307 connected to it rotates accordingly, and finally drives the laser weld seam tracker 308 to rotate, thereby adjusting the angle of the laser weld seam tracker 308. It should be noted here that the model number of the laser weld seam tracker 308 is "CXZK-RBTA4-S".

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
