Description

Technical Field

[0001] The utility model relates to the technical field of pipeline internal welding machines, in particular to a pipeline internal annular seam visual monitoring system. Background Art

[0002] Pipeline welding is a common welding process in the industrial field, which is used to connect different parts of the pipeline. It is a very important link in pipeline engineering, which is directly related to the quality and reliability of the pipeline. In the traditional pipeline welding process, due to the influence of factors such as temperature, pressure and materials during the welding process, problems such as poor weld quality, welding deformation and welding cracks may occur during the welding process. The welder needs to enter the welded pipeline and observe the welding area with the naked eye to ensure the welding quality and safety. This method has limitations. On the one hand, it is inefficient, and on the other hand, it is unsafe. Therefore, an efficient and safe detection method is needed instead. Utility Model Content

[0003] The main purpose of the utility model is to provide a visual monitoring system for annular seams in pipelines, which can effectively solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The pipeline inner annular seam visual monitoring system comprises an inner welding machine cage, wherein a top plate is arranged on the top of the inner welding machine cage, a protective tube is installed on the surface of the top plate, a retractable camera is accommodated inside the protective tube, and a driving mechanism is connected to the bottom of the camera, and the driving mechanism is installed on the bottom surface of the top plate and located inside the inner welding machine cage.

[0006] Preferably, the protection tube is fixedly welded to the center of the surface of the top plate, and is reinforced by welding ribs around it.

[0007] Preferably, the driving mechanism mainly includes an electric push rod, the top end of which is mounted on a bracket by screws, the bracket is fixedly connected to a mounting flange, and the mounting flange is fixedly mounted to the bottom surface of the top plate by screws.

[0008] Preferably, the output end push rod of the electric push rod passes through the top plate and is fixedly connected to the bottom of the camera. The bottom surface of the camera is also connected to four sliding limit guide rods. The bottom of the sliding limit guide rods passes through the top plate and each is slidably connected to the bracket through an oil-free bearing.

[0009] Preferably, a circular dustproof seal is installed on the top of the protection tube. The dustproof seal is made of rubber and has a gap in the center for the camera to enter and exit.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, a protection tube is firstly arranged at the front end of the inner welding machine cage, and a high-definition camera is arranged in the protection tube. The high-definition camera can be used to quickly monitor and check the quality of the weld instead of manual work. At the same time, a driving mechanism is also connected to the bottom of the camera.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] like Figure 1 As shown, the visual monitoring system for the inner annular seam of a pipeline includes an inner welding machine cage 1. A top plate 2 is provided on the top of the inner welding machine cage 1. A protective tube 5 is installed on the surface of the top plate 2. The protective tube 5 is fixedly welded at the center of the surface of the top plate 2 and is welded and reinforced by rib plates 6 around it. A camera 4 for monitoring the weld is arranged and stored in the protective tube 5.

[0021] like Figure 2-Figure 5 As shown, the driving mechanism 3 mainly includes an electric push rod 8, the top end of the electric push rod 8 is mounted on a bracket 9 by screws, the bracket 9 is fixedly connected to a mounting flange 10, and the mounting flange 10 is fixedly mounted to the bottom surface of the top plate 2 by screws. The output end push rod of the electric push rod 8 passes through the top plate 2 and is fixedly connected to the bottom of the camera 4. The bottom surface of the camera 4 is also connected to four sliding limit guide rods 11, and the bottom of the sliding limit guide rods 11 passes through the top plate 2, and each is slidably connected to the bracket 9 through an oil-free bearing.

[0022] In this embodiment, in order to seal and protect the camera 4 inside the protection tube 5, a circular dustproof seal 7 is installed on the top of the protection tube 5. The dustproof seal 7 is made of rubber and has a gap in the center for the camera 4 to enter and exit.

[0023] In actual use, the inner welding machine cage 1 drives the welding machine into the pipeline for welding. During the welding process, the electric push rod 8 is in a retracted state, and the camera 4 is completely retracted into the protective tube 5. At this time, the rubber dust seal 7 on the top of the protective tube 5 can block the protective tube 5, effectively preventing welding slag, smoke, etc. from entering the protective tube 5 and damaging the camera 4. When the welding is completed and the weld needs to be inspected and monitored, it is only necessary to start the electric push rod 8 to push the camera 4 out of the protective tube 5. Since the dust seal 7 has a gap in the middle and is made of soft rubber material, the camera 4 can easily extend out of the protective tube 5, and during the extension process, a sliding limit guide rod 11 is set between the bottom of the camera 4 and the bracket 9 to ensure that the camera 4 is extended in a straight line, thereby avoiding bumping against the inner wall of the protective tube 5. After the camera 4 is extended, based on the high-definition camera technology built into the camera 4, the image of the welding process can be captured in real time. The high-definition image quality can provide clear visual information to help operators accurately observe the details of the welding process, and by processing and analyzing the image data of the welding process, the system can accurately detect the quality problems of the weld. Image processing technology can enhance, filter and detect edges of images to improve the accuracy and reliability of welding quality. During the inspection process, once poor weld quality or other problems are found, the system will immediately issue an alarm so that the operator can take timely measures to repair and adjust. At the same time, the camera 4 can record and store a large amount of data and images, providing a reliable basis for the maintenance and management of the pipeline. The operator can understand the problems and room for improvement in the welding process through the analysis of data and images, and improve the quality and safety of the pipeline. After the inspection is completed, the electric push rod 8 moves again, cooperates with the sliding limit guide rod 11 to retract the camera 4 into the protective tube 5, and then the welding operation can continue.
