[0027] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings constitute a part of the present application and are used to explain the principles of the present application together with the embodiments of the present application, but are not used to limit the scope of the present application.

[0028] Embodiment 1

[0029] The present embodiment 1 relates to a pipeline plugging device, as shown in the drawings, which is suitable for being assembled with a mechanical arm of a robot to achieve remote plugging by driving the mechanical arm. Figure 1

[0030] Referring to Figures 2-3 , the pipeline plugging device 200 comprises a main support plate 201, an adsorption module, a pressure connection module, and a prefabricated part 206. The main support plate 201 is suitable for being connected with the mechanical arm; the adsorption module is floatingly arranged on the main support plate 201; the pressure connection module is floatingly arranged on the adsorption module, and the pressure connection module is used for tightly pressing and pasting the prefabricated part 206 to the leakage point of the pipeline to achieve plugging.

[0031] The adsorption module comprises a magnet connecting frame 204, an electric permanent magnet 203, a first guide rod 202, and a first spring. The electric permanent magnet 203 is provided with two, which are floatingly connected with the main support plate 201 through the first guide rod 202 and the first spring. At the same time, the two electric permanent magnets 203 are connected into one through the magnet connecting frame 204.

[0032] Among them, the main support plate 201 is suitable for being fixedly connected with the tail end of the mechanical arm, and the main support plate 201 has a plurality of first through holes, and each first through hole is slidingly arranged with a first guide rod 202. Preferably, four first through holes and four first guide rods 202 are arranged on both sides of the main support plate 201. The bottom of the first guide rod 202 on the same side is fixedly connected to an electric permanent magnet 203. Two first springs are sleeved on each first guide rod 202, one of which is located above the main support plate 201 and between the screw nut at the top of the main support plate 201 and the first guide rod 202; the other first spring is located below the main support plate 201 and between the main support plate 201 and the electric permanent magnet 203. Through the two first springs above and below, the position of the electric permanent magnet 203 relative to the main support plate 201 is maintained within a predetermined range and can be adaptively adjusted. Through this arrangement, the electric permanent magnet 203 can float up and down relative to the main support plate 201, so that in the process of driving plugging by the mechanical arm, buffering can be achieved to avoid bumping and reduce the requirement for positioning accuracy.

[0033] The magnet connecting frame 204 is an H-shaped frame body, comprising two vertical side plates and a horizontal cross plate. The two electric permanent magnets 203 are fixedly connected to the outer side surfaces of the two side plates of the magnet connecting frame 204. The magnet connecting frame 204 and the two electric permanent magnets 203 constitute an integral whole, which can float up and down as a whole relative to the main support plate 201.

[0034] The pressure connection module is floatingly arranged on the cross plate in the middle of the magnet connecting frame 204. The pressure connection module comprises a second guide rod 207, a pressure plate 205, a second spring, a pressure plate, and a vacuum chuck. ​

[0035] The middle part of the magnet connecting frame 204 is provided with a plurality of second through holes, and a second guide rod 207 is slidably arranged in each second through hole. Preferably, there are four second through holes. The bottom of the four second guide rods 207 is fixedly connected to the pressure plate 205. Two second springs are sleeved on each second guide rod 207. One of the second springs is arranged above the horizontal plate of the magnet connecting frame 204, between the magnet connecting frame 204 and the nut at the top of the second guide rod 207; the other second spring is arranged below the horizontal plate of the magnet connecting frame 204, between the magnet connecting frame 204 and the pressure plate 205. In this way, the position of the pressure plate 205 relative to the magnet connecting frame 204 is kept within a predetermined range, and at the same time, the pressure plate 205 can float up and down relative to the magnet connecting frame 204.

[0036] The lower surface of the electromagnet 203 and the pressure plate 205 is a circular arc surface.

[0037] The middle part of the pressure plate 205 is provided with a third through hole, and a vacuum chuck is arranged in the third through hole. The vacuum chuck is in communication with a vacuum pump through a pipeline. The bottom surface of the vacuum chuck is flush with the bottom surface of the pressure plate 205.

[0038] The lower surface of the pressure plate 205 protrudes from the lower surface of the electromagnet 203 on both sides by 5-10 mm. In this way, the prefabricated part 206 can be easily grabbed, and at the same time, the pressing process can be facilitated by the second spring providing a pressing force.

[0039] Preferably, the elastic coefficient of the second spring is smaller than that of the first spring. In this way, the distance between the electromagnet 203 of the pipeline plugging device and the main support plate 201 can be kept stable and not easily deformed, thereby ensuring accurate positioning. At the same time, the robot arm does not need to overcome too much resistance to press the pressure plate 205, thereby improving the reliability of the operation.

[0040] The pipeline plugging device 200 further comprises a storage box and a glue applying module.

[0041] Preferably, the storage box can be arranged on the robot body, and the storage box stores the prefabricated part 206. The storage box can be arranged on the robot body or an additional device (such as a trolley), so as to facilitate the selection and grabbing of the corresponding prefabricated part according to the pipe specifications.

[0042] The prefabricated part 206 is an arc-shaped steel plate, and a vulcanized annular sealing ring is installed on the inner side to ensure the sealing effect. The arc surface of the prefabricated part 206 is adapted to the outer surface of the pipeline 100. If there are pipelines 100 of multiple diameters that need to be maintained, the prefabricated part 206 can be prepared in multiple specifications, and the corresponding prefabricated part 206 can be grabbed according to the specifications of the pipeline.

[0043] The glue coating module can be arranged on the robot body or an additional device (such as a trolley) and is used for coating the composite mastic on the prefabricated part 206. The glue coating module is composed of an automatic mixing pipe and an electric rod. The automatic mixing pipe is used for mixing two components of AB glue, so as to ensure the uniformity and adhesion of the mastic. The mixed mastic is pushed into the sealing ring of the prefabricated part by the electric rod. During operation, the electric rod controls the amount and coating position of the mastic, so as to ensure the plugging effect.

[0044] During operation, the mechanical arm drives the main support plate 201, and drives the whole pipeline plugging device to move to the position of the storage box. The vacuum pump is opened, and a prefabricated part 206 is taken by the vacuum chuck. Then, the glue coating module automatically coats glue on the prefabricated part 206.

[0045] After the glue coating is completed, the mechanical arm drives the main support plate 201, and drives the whole pipeline plugging device to move to the leakage point of the pipeline. The center of the prefabricated part 206 on the pressure plate 205 is aligned with the leakage point, and then the pipeline plugging device is pressed on the pipeline. After the prefabricated part 206 contacts the pipeline wall, the mechanical arm continues to press down, at this time, the pressure plate 205 overcomes the force of the second spring and retracts, so that the lower surfaces of the two electric permanent magnets 203 are flush with the lower surface of the prefabricated part 206, and are tightly pressed on the pipeline.

[0046] At this time, the two electric permanent magnets 203 are electrified, so that the two electric permanent magnets 203 are tightly adsorbed on the surface of the pipeline. At the same time, the pressure plate 205 also tightly presses the prefabricated part 206 under the action of the second spring, so that the prefabricated part 206 can be firmly pasted on the surface of the pipeline, and the plugging is realized.

[0047] The pipeline plugging device can realize remote operation of the robot for pipeline leakage repair. The system has high operation flexibility, high plugging efficiency, can work without stopping, the robot itself has strong expandability, can accurately plug the pipeline leakage point, and uses the composite mastic combined with the strong magnetic tape pressure sealing technology to ensure the sealing effect of the pipeline leakage point.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
