The extension device 1 includes an extension bracket 4, an alignment plate 5, a vertical guide rail 6 and an anti-slip sheet 7. The alignment plate 5 is fixedly installed on the side end of the extension bracket 4, the vertical guide rail 6 is fixedly installed at the front bottom of the extension bracket 4, and the anti-slip sheet 7 is fixedly installed at the bottom center of the vertical guide rail 6. The supporting device 3 includes a pipe 15, a supporting base plate 16 and a second sealing strip 17. The supporting base plate 16 is fixedly installed on both sides of the pipe 15, and the second sealing strip 17 is fixedly installed on the front end of the pipe 15.

[0021] The positioning device 2 includes a supporting cross frame 8, a guide front rod 9, a hydraulic cylinder 10, a limit rod 11, a sleeve plate 12, a first sealing strip 13 and a pipe head 14. The sleeve plate 12 is fixedly installed at both ends of the supporting cross frame 8, the limit rod 11 is slidably inserted into the inner part of the end of the sleeve plate 12 away from the supporting cross frame 8, the hydraulic cylinder 10 is fixedly installed in the inner center of the supporting cross frame 8, the pipe head 14 is fixedly installed in the center of the end of the hydraulic cylinder 10 away from the supporting cross frame 8, the first sealing strip 13 is fixedly installed on the outer ring of the side end of the pipe head 14 away from the hydraulic cylinder 10, the guide front rod 9 slides symmetrically through the supporting cross frame 8 and is connected to the side end of the pipe head 14 away from the first sealing strip 13, and is slidably sleeved on the vertical guide rail 6 through the sleeve plate 12, so that the supporting cross frame 8 can be guaranteed to move up and down in a straight line.

[0022] The sleeve plate 12 is slidably sleeved on the vertical guide rail 6 , and the extension bracket 4 is fixedly mounted on the side end of the support base plate 16 to support the vertical guide rail 6 to work.

[0023] Round holes are provided at the center of the side end of the alignment plate 5 and the top end of the sleeve plate 12 to facilitate the docking of the limiting rod 11 with the alignment plate 5 .

[0024] The diameter of the second sealing strip 17 is 2 cm larger than that of the first sealing strip 13 . The first sealing strip 13 and the second sealing strip 17 are respectively fitted and fastened to the pipe head 14 and the pipe 15 , so that the anti-leakage property between the pipe head 14 and the pipe 15 can be enhanced.

[0025] The diameters of the pipeline end cap 14 and the pipeline 15 are equal, so that the pipeline end cap 14 and the pipeline 15 can be accurately connected.

[0026] Working principle: during use, when the user needs to observe the inside of the pipe 15, the hydraulic cylinder 10 can be started to drive the pipe head 14 to disengage from the pipe 15. At this time, the guide front rod 9 slides inside the supporting cross frame 8, so that the pipe head 14 can be supported to move in a straight line. Thereafter, when the pipe head 14 is disengaged from the pipe 15, the limiting plug rod 11 can be pulled to the front end until the limiting plug rod 11 is moved out of the inside of the sleeve plate 12, so that the sleeve plate 12 can be released. The sleeve plate 12 is slidably sleeved on the two vertical guide rails 6, so that the sleeve plate 12 will drive the supporting cross frame 8 to slide downward, so that the pipe head 14 can be misaligned with the pipe 15, which is convenient for the user to observe the internal condition of the pipe 15. Subsequently, when the sleeve plate 12 moves downward to the limit position, the anti-dropping sheet 7 is set to prevent the sleeve plate 12 from falling off. When the user has finished observing the inside of the pipe 15, the supporting cross frame 8 is moved upward. , until the sleeve plate 12 moves upward to the limit position and contacts with the extension bracket 4, so that the pipe head 14 can be aligned with the pipe 15, completing the work of accurately aligning the pipe head 14 and the pipe 15. At the same time, when the supporting cross frame 8 moves upward to the limit position, it can also drive the circular hole inside the side end of the sleeve plate 12 to be vertically aligned with the circular hole in the center of the side end of the alignment plate 5, and the limiting plug rod 11 can be slidably inserted into the sleeve plate 12 and the alignment plate 5, so that the sleeve plate 12 can be restricted on the alignment plate 5 to prevent the pipe head 14 from falling again. After that, the hydraulic cylinder 10 can be started to drive the pipe head 14 and the pipe 15 to approach each other, until the pipe head 14 and the pipe 15 are fitted together, and the first sealing strip 13 and the second sealing strip 17 can be driven to fit and tighten with the pipe 15 and the pipe head 14 respectively, so that leakage between the pipe head 14 and the pipe 15 can be prevented, completing the work of facilitating observation of the inside of the pipe 15.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
