Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection auxiliary equipment, and in particular to a pipeline inspection auxiliary device. Background Technology

[0002] refer to Figure 1 For CCTV inspection of pipelines, a pipeline robot needs to be placed into the rainwater or sewage pipe through a manhole. If the pipeline and the manhole form a level passage, as shown in pipe A in the diagram, the pipeline robot can naturally enter the pipeline for inspection after being placed at the bottom of the manhole. However, if there is a significant height difference between the bottom of the pipeline and the bottom of the manhole, as shown in pipe B, or even if points B and C in the diagram are not on the same vertical section, the pipeline robot cannot be placed at the bottom of the manhole for inspection. In this case, manual entry is required to guide the pipeline robot into pipe B. Since manual entry into the manhole for pipeline inspection is a confined space operation, it affects personal safety and inspection efficiency. Therefore, a pipeline inspection auxiliary device is provided to enable the pipeline robot to inspect pipelines with different elevations than the bottom of the manhole without manual entry.

[0055] In use, the bottom support frame 1 supports the extension mechanism. The extension mechanism enters the well from the wellhead and is driven by the linear moving component 5 to move the upper plate 6 to the corresponding pipe opening, so as to connect the middle plate 4 with the pipe opening, which facilitates the pipeline robot to enter the pipeline for inspection.

[0056] In this embodiment, an expansion groove is provided on one side of the upper plate 6, and an electric push rod 8 and an expansion plate 9 are installed in the expansion groove. The piston rod of the electric push rod 8 is connected to the expansion plate 9.

[0058] In this embodiment, a ramp is provided on the side of the upper plate 6 near the starting position of the linear moving component 5 to facilitate the guide tube robot to enter the upper plate 6 from the middle plate 4.

[0059] In this embodiment, hanging rings 7 are provided on all four sides of the bottom plate 2 or the middle plate 4. The hanging rings 7 facilitate the lowering of this application into the well via cables.

[0063] The movable block is slidably mounted on the movable bracket and threadedly connected to the lead screw; the top of the movable block is connected to the upper plate 6.

[0064] In use, the motor drives the lead screw to rotate, which in turn moves the moving block on the lead screw along the length of the lead screw, thereby enabling the middle plate 4 to move toward the pipe opening.

[0065] In this embodiment, the bottom support frame 1 includes a top support plate 11, a support shaft 12, a support rod 14, a folding rod 15, and a lifting sleeve 13;

[0069] One end of the folding rod 15 is hinged to the middle of the support rod 14, and the other end of the folding rod 15 is hinged to the bottom end of the support shaft 12.

[0070] In use, the angle of each support rod 14 can be adjusted by sliding the lifting sleeve 13, so that it can be smoothly entered from the wellhead. The sliding of the lifting sleeve 13 can also fold each support rod 14 for easy carrying.

[0071] In this embodiment, the support rod 14 is a telescopic rod.

[0072] In this embodiment, the insert plate 10 is installed at one end of the upper plate 6. The insert plate 10 is pointed.

During the movement of the pipeline robot, the insert plate 10 can prevent the auxiliary device from falling over.

[0073] The working principle of this utility model is as follows:

[0074] The bottom support frame 1 is used to support the extension mechanism. The extension mechanism enters the well from the wellhead and is driven by the linear moving component 5 to move the upper plate 6 to the corresponding pipe opening, so as to connect the middle plate 4 with the pipe opening, which facilitates the pipeline robot to enter the pipeline for inspection.
