Description

Technical Field

[0001] The utility model relates to the technical field of rust removal of natural gas pipelines, in particular to a rust removal machine for natural gas pipeline maintenance. Background Art

[0002] As gas flows in natural gas pipelines, condensation water is generated on the outer wall of the pipeline, causing the pipeline to rust. Usually, sandpaper and iron brushes are used to remove rust, polish and paint, which is time-consuming, labor-intensive and inefficient.

[0003] Therefore, a rust remover for natural gas pipeline maintenance in the prior art has a publication number of CN210226038U. A person slowly pushes the natural gas pipeline to the right. When the natural gas pipeline moves between two scraping bars, the rotating scraping bars rub the rust on the outer wall of the natural gas pipeline. At the same time, the sprayed rust remover is sprayed onto the natural gas pipeline. The rust remover reacts chemically with the rust on the natural gas pipeline to achieve a preliminary rust removal effect. The rust on the outer wall of the natural gas pipeline can be effectively cleaned through the friction of the scraping bars and the spraying of the rust remover. The multiple long bristles in the second rotating tube rub the outer wall of the natural gas pipeline again, and the remaining rust adhering to the outer wall of the natural gas pipeline can be removed by friction, thereby achieving the effect of thoroughly cleaning the rust on the outer wall of the natural gas pipeline.

[0004] However, the prior art requires the natural gas pipeline to be pushed to move in the equipment, but the natural gas pipeline is generally fixed. Therefore, when using the prior art equipment to remove rust, the natural gas pipeline needs to be removed and then reinstalled, which is more troublesome, that is, it is not suitable for fixed natural gas pipelines.

[0022] like Figure 1-3As shown, a rust removal machine for natural gas pipeline maintenance includes a plurality of first clamping seats 3 that are plugged into the outer wall of the natural gas pipeline and move along the distribution direction of the natural gas pipeline, wherein a second clamping seat 7 is fixedly connected to the first clamping seat 3 at one end thereof, and as shown in the figure, the first clamping seat 3 and the second clamping seat 7 are both U-shaped, so that the first clamping seat 3 and the second clamping seat 7 can be smoothly sleeved on the outer wall of the natural gas pipeline, a guide rail 15 for sleeved on the outer wall of the natural gas pipeline is fixedly connected to one side of the second clamping seat 7, a swivel 8 is rotatably connected to the guide rail 15, a gear ring 9 is fixedly connected to the inner side of one end of the swivel 8, and a spur gear 1 meshing with the outer side tooth surface of the gear ring 9 is rotatably connected to the second clamping seat 7. 4, and in order to drive the spur gear 14 to rotate, a conventional method of installing a motor on the second card seat 7 can be selected to drive the spur gear 14 to rotate, one end of the gear ring 9 extends outward, and is plugged with a telescopic seat 10 for sliding along the length direction of the natural gas pipeline, the outward extension portion of the gear ring 9 passes through a first electric push rod 12 fixedly connected with a telescopic end and one end of the telescopic seat 10, and passes through a guide rod 17 with one end fixedly connected to the other end of the telescopic seat 10, the first electric push rod 12 and the guide rod 17 are parallel to the center line of the second card seat 7, that is, when the second card seat 7 is sleeved on the natural gas pipeline, the first electric push rod 12 and the guide rod 17 are parallel to the center line of the natural gas pipeline, so through the limiting support effect of the guide rod 17, the first electric push rod 12 is used to push the telescopic seat 10 to slide along the center line of the natural gas pipeline, and the spur gear 14 and the extended extension part of the gear ring 9 and the cylinder body part of the first electric push rod 12 are staggered, and the first electric push rod 12 is located on the side of the spur gear 14 away from the gear ring 9, and in actual use, the straight part of the U-shaped second card seat 7 can be taken out, and the arc part is retained, so that the first electric push rod 12 can smoothly rotate with the rotation of the gear ring 9, and the telescopic seat 10 is plugged with a connecting seat 1 for sliding toward the natural gas pipeline. 6. A second electric push rod 11 for driving the connection seat 16 to move is fixedly connected to the telescopic seat 10. A plurality of wire brushes 13 for rust removal are fixedly connected to the connection seat 16 at one end facing the natural gas pipeline. The second electric push rod 11 is used to push the connection seat 16 and the wire brush 13 on its end face to fit the outer wall of the natural gas pipeline. The telescopic seat 10 drives the connection seat 16 to rotate by rotating the gear ring 9.

[0024] In order to realize the sliding of the first card seat 3 along the outer wall of the natural gas pipeline, the following scheme is adopted: a plurality of electric wheels 5 distributed in a circular array and used for rolling connection with the outer wall of the natural gas pipeline are inserted in the first card seat 3. When the first card seat 3 is sleeved on the outer wall of the natural gas pipeline, the center line of the electric wheel 5 is perpendicular to the center line of the natural gas pipeline. Therefore, when the tire surface of the electric wheel 5 is against the outer wall of the natural gas pipeline, the electric wheel 5 can be prevented from rotating along the circumferential surface of the outer wall of the natural gas pipeline, that is, the electric wheel 5 is started to drive the first card seat 3 and the second card seat 7 to move along the extension direction of the natural gas pipeline. A connecting shaft 6 that passes through the first card seat 3 is fixedly connected to the shell of the electric wheel 5, and a connecting shaft 6 that passes through the first card seat 3 and is fixedly connected to the connecting shaft 6 is fixedly connected to the first card seat 3. The first electric telescopic rod 4 for driving the electric wheel 5 to move is distributed parallel to the connecting shaft 6. The first electric telescopic rod 4 is extended and retracted, and under the limiting action of the connecting shaft 6, the electric wheel 5 clamps the outer wall of the natural gas pipeline of different sizes as the first electric telescopic rod 4 is extended and retracted. A plurality of second electric telescopic rods 1 are arranged between two adjacent first clamping seats 3. The telescopic ends and cylinder end surfaces of the second electric telescopic rods 1 are rotatably connected to the spiral seats 2 spirally connected to the first clamping seats 3. The spiral seats 2 are used to connect the second electric telescopic rods 1 to the two adjacent first clamping seats 3, and the distance between the two adjacent first clamping seats 3 is adjusted by the extension and retraction of the second electric telescopic rods 1, so that the device can smoothly pass through the bend of the natural gas pipeline.

[0025] The method of use is to contract the first electric telescopic rod 4 to move the corresponding electric wheel 5 close to the inner wall of the first clamping seat 3, and use the second electric telescopic rod 1 to assemble two adjacent first clamping seats 3, and put the assembled first clamping seats 3 on the natural gas pipeline, and then extend the first electric telescopic rod 4 to realize the corresponding electric wheel 5 to move to clamp the outer wall of the natural gas pipeline, and then fix the other part of the guide rail 15 to the second clamping seat 7 by bolts, and extend the second electric push rod 11 to realize the wire brush 13 on the end face of the connecting seat 16 to fit the outer wall of the natural gas pipeline, and use the spur gear 14 to rotate and drive the gear ring 9 to drive the telescopic seat 10 to rotate, and start the electric wheel 5 to drive the first clamping seat 3 and the second clamping seat 7 to move along the outer wall of the natural gas pipeline, so that the connecting seat 16 drives the wire brush 13 to rotate, so as to realize the rust removal of the circumferential surface of the outer wall of the natural gas pipeline.
