Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline processing device. Background Art

[0002] At present, 100% penetration testing of the inner and outer surfaces is mainly carried out on two specifications of pipes. One specification has an inner hole diameter of φ550mm and a length of approximately 8000mm; the other specification has an inner hole diameter of φ550mm and a length ranging from 2000mm to 9000mm.

[0003] Because dust, debris, and other debris accumulate on the inner walls of pipes during manufacturing, processing, and use, they must be cleaned before conducting a pipe penetration test. Currently, the traditional method involves extending a high-pressure cleaning head into the pipe to flush the inner walls. Due to the high water pressure required and the poor stability of the high-pressure water pipe's end, the movement of the high-pressure cleaning head is uncontrollable, which can easily cause the high-pressure cleaning head to collide with the inner wall of the pipe, causing damage to the high-pressure cleaning head or the inner wall of the pipe. Another method involves inspectors manually performing the pipe cleaning or penetrant application process inside the pipe. These inspectors crawl into the inner hole to perform the operation. Given the human anatomy, the shoulder width of an adult is approximately 500 mm, only slightly larger than a small-diameter hole. This significantly limits the ease of operation even within large pipes. The inspector relies on abdominal strength and elbow support to drag their body forward, resulting in low efficiency and extremely labor-intensive work. Utility Model Content

DETAILED DESCRIPTION

[0020] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] like Figure 1-Figure 3 As shown, the utility model provides a pipeline processing device, including a mounting cylinder 1, at least two mounting brackets 2 are arranged along the circumference of the mounting cylinder 1, and each mounting bracket 2 is rotatably provided with a walking wheel 3 away from the end of the mounting cylinder 1, the outer peripheral surface of the walking wheel 3 abuts the inner wall of the pipe 22, and the rolling axis of the walking wheel 3 is perpendicular to the axis of the mounting cylinder 1; a nozzle 4 is provided at the end of the mounting cylinder 1, and the nozzle 4 is provided with a plurality of nozzles 5 opposite to the inner wall of the pipe 22 along its circumference, and a delivery pipe 6 connected to the inner cavity of the nozzle 5 is provided on the nozzle 4; a driving mechanism 7 for driving the mounting cylinder 1 to move axially along the pipe 22 is provided on the mounting cylinder 1.

[0022] Among them, the mounting cylinder 1 is coaxially arranged with the pipe 22, and the mounting bracket 2 can be fixedly connected to the mounting cylinder 1. When there are two mounting brackets 2, the two mounting brackets 2 are arranged at an interval of 180 degrees. When there are three mounting brackets 2, the three mounting brackets 2 are arranged at an interval of 120 degrees. The mounting bracket 2 is used to install the walking wheel 3, and the walking wheel 3 is rotatably connected to the mounting bracket 2 through a bearing. During use, the outer peripheral surface of the walking wheel 3 abuts against the inner wall of the pipe 22. When the driving mechanism 7 drives the mounting cylinder 1 to move, the walking wheel 3 rolls along the inner wall of the pipe 22, and the rolling axis of the walking wheel 3 is aligned with the inner wall of the mounting cylinder 1. The axis is vertical, so that the rolling track of the walking wheel 3 is parallel to the axis of the installation tube 1; the nozzle 4 is set at the rear end position of the moving direction of the installation tube 1, and the nozzle 4 can be fixedly connected to the mounting seat 701 by bolts. The nozzle 4 is provided with multiple nozzles 5 opposite to the inner wall of the pipe 22 along its circumference. Water or penetrant is delivered to the nozzle 4 through the delivery pipe 6 and sprayed out through the nozzles 5 on the nozzle 4 to achieve the cleaning of the inner wall of the pipe 22 or the application of penetrant. The delivery pipe 6 can be connected to the water tank outside the pipe 22, or a water tank can be set on the installation tube 1 to provide water or penetrant. The driving mechanism 7 can use a driving trolley, which is connected to the installation tube 1 by a pull rope. The driving trolley moves along the pipe 22 in the pipe 22 to drive the installation tube 1 to move along the pipe 22, thereby achieving the cleaning of the inner wall of the pipe 22 or the application of penetrant.

[0023] In order to improve the applicability of the device, further see Figure 1The mounting bracket 2 includes a first connecting rod 8, a second connecting rod 9 and a sleeve 10. The first connecting rod 8 and the second connecting rod 9 are cross-arranged and hinged; the sleeve 10 is sleeved on the mounting tube 1 and can move along the axial direction of the mounting tube 1. The lower end of the first connecting rod 8 is hinged to the sleeve 10, and the lower end of the second connecting rod 9 is hinged to the mounting tube 1. The walking wheel 3 is arranged at the upper end of the first connecting rod 8 and the upper end of the second connecting rod 9. Among them, the first connecting rod 8 and the second connecting rod 9 are cross-connected by rivets; the first connecting rod 8 and the second connecting rod 9 have the same shape and size, both are long strips, and hinge holes are respectively punched in the center and lower ends of the two connecting rods. The two connecting rods are connected together by rivets passing through the central hinge holes of the two connecting rods, and both connecting rods can rotate around the rivets; the inner diameter of the sleeve 10 is larger than the outer diameter of the mounting tube 1, so that the sleeve 10 can be sleeved on the mounting tube 1 and can move relative to the mounting tube 1; a hinge is installed on the outer surface of the sleeve 10 The connecting seat makes the lower end of the first connecting rod 8 hinged to the sleeve 10, and the hinge seat is installed on the outer surface of the mounting tube 1, so that the lower end of the second connecting rod 9 is hinged to the mounting tube 1. In this way, when the sleeve 10 is moved, the ends of the first connecting rod 8 and the second connecting rod 9 away from the mounting tube 1 can be extended or retracted; the inner ring of the bearing is set at the end of the first connecting rod 8 and the second connecting rod 9 away from the mounting tube 1, and the outer ring of the bearing is fixedly connected to the walking wheel 3, so that the rotation of the walking wheel 3 relative to the first connecting rod 8 and the second connecting rod 9 can be realized.

[0024] Further, see Figure 2 A manifold 11 is provided in the inner cavity of the nozzle 4, and the delivery pipe 6 is connected to the inner cavity of the manifold 11. The manifold 11 is provided with multiple connecting pipes 12 along its circumference, and a pressure equalizing pipe 13 is provided at the end of the connecting pipe 12. The multiple pressure equalizing pipes 13 form a circular structure, and each of the pressure equalizing pipes 13 is provided with multiple nozzles 5. The connecting pipe 12 is connected to the manifold 11, and the water or penetrant in the manifold 11 is introduced into the pressure equalizing pipe 13. The cross-sectional size of the pressure equalizing pipe 13 is larger than the cross-sectional size of the connecting pipe 12. The pressure equalizing pipe 13 can be fixed in the inner cavity of the nozzle 5 by a clamping ring, and the manifold 11 can be fixed in the inner cavity of the nozzle 4 by bolts; by arranging the pressure equalizing pipe 13 at the end of the connecting pipe 12, the cross-sectional size of the pressure equalizing pipe 13 is larger than the cross-sectional size of the connecting pipe 12. After the water or penetrant flows from the connecting pipe 12 into the pressure equalizing pipe 13, the water or penetrant will be pressure-equalized in the pressure equalizing pipe 13. In this way, the pressure of the water or penetrant sprayed out by the nozzle 5 on each pressure equalizing pipe 13 is the same, which can better control the water or penetrant pressure and flow on the inner wall of the pipe 22 corresponding to the pressure equalizing pipe 13.

[0025] In order to make the inner wall of the pipe 22 clean or the penetrant applied more uniformly, further see Figure 1 and Figure 2The mounting tube 1 is provided with a drive device that drives the spray head 4 to rotate about its axis. The manifold 11, mounting tube 1, and spray head 4 are all coaxially arranged. The manifold 11 is connected to the delivery pipe 6 via a dynamic seal assembly, which is coaxial with the manifold 11. The drive device includes a drive motor 14 provided on the mounting tube 1. The output end of the drive motor 14 is provided with a drive gear 15. The spray head 4 is provided with a driven gear 16 coaxial with the spray head 4. The drive gear 15 cooperates with the driven gear 16, and the spray head 4 is connected to the mounting tube 1 with a bearing. In this arrangement, the drive motor 14 drives the drive gear 15 to rotate, which in turn drives the driven gear 16 to rotate. Under the action of the bearing, the spray head 4 rotates about its own axis. At the same time, the manifold 11 is connected to the delivery pipe 6 via a dynamic seal assembly to ensure the sealing between the delivery pipe 6 and the manifold 11. The dynamic seal assembly can adopt the rotary seal assembly mentioned in CN217583164U.

[0026] To facilitate the application of the penetrant, the nozzle 5 is further configured as an atomizing spray nozzle, the axis of which is perpendicular to the inner wall of the pipe 22. The atomizing spray nozzle can atomize the penetrant in the pressure equalizing tube 13 and spray it onto the inner wall of the pipe 22. If the axis of the nozzle 5 is not perpendicular to the inner wall of the pipe 22, the sprayed penetrant will have a horizontal force component, causing the penetrant to slip when sprayed onto the inner wall of the pipe 22. Therefore, aligning the axis of the nozzle 5 perpendicular to the inner wall of the pipe 22 ensures the stability of the penetrant sprayed onto the inner wall of the pipe 22.

[0027] In order to facilitate the cleaning of impurities on the inner wall of the pipe 22, the nozzle 5 is further configured as a high-pressure nozzle 5, and the axis of the nozzle 5 forms a 30° angle with the inner wall of the pipe 22. The 30° angle between the axis of the nozzle and the inner wall of the pipe 22 allows the ejected water column to be sprayed onto the inner wall of the pipe 22 at a 30° angle. The water column generates a horizontal force component, which can more easily separate impurities on the inner wall of the pipe 22 from the inner wall of the pipe 22.

[0028] In order to understand the internal state of the pipe 22, see Figure 1 The nozzle 4 is provided with an illumination lamp 17 and a camera 19 .

[0029] In the above embodiment, the driving mechanism 7 adopts a driving trolley. When the driving trolley is in use, it moves on the inner surface of the pipe 22, which may damage the inner surface of the pipe 22. Figure 1The driving mechanism 7 includes a mounting base 701 disposed outside the pipe 22. A take-up wheel 702 is rotatably connected to the mounting base 701. The take-up wheel 702 is connected to the mounting drum 1 via a connecting rope 703. The mounting base 701 is set on the floor of the workshop. The take-up wheel 702 is connected to the mounting base 701 via a bearing. The take-up wheel 702 can be driven to rotate by a motor. As the take-up wheel 702 rotates, the connecting rope 703 is gradually wound around the take-up wheel 702, thereby driving the mounting drum 1 to move along the axis of the pipe 22.

[0030] Further, see Figure 1 A storage tank 19 is provided outside the pipe 22. The delivery pipe 6 is in communication with the inner cavity of the storage tank 19. A booster pump 20 and a pressure gauge 21 are provided on the delivery pipe 6. The storage tank 19 is used to store water or osmotic agent. The booster pump 20 is used to pump the water or osmotic agent in the storage tank 19 into the delivery pipe 6 and increase the delivery pressure of the delivery pipe 6. The pressure gauge 21 is used to monitor the delivery pressure in the delivery pipe 6.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
