[0025] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0026] Example: See attached Figure 1-4 As shown, the plug-and-play steel pipe PT detection frame includes a mobile frame 11, the power of which can be provided by an external telescopic rod but is not limited to the telescopic rod.

The pipeline 12 can be provided with accessories such as a spray pump. The pipeline 12 is provided with a quick-connect connector 14 that can be plugged and connected to the spray gun 2. The quick-connect connector 14 is a hollow structure, which provides a prerequisite for the passage of the spray liquid such as the penetrant. The quick-connect connector 14 is a prior art and is not described in detail here. It is introduced that the end of the wire 13 is provided with an electric connector 15 fixed on the mobile frame 11 and can be plugged with the terminal head 30 of the camera device 3. The electric connector 15 can be fixed to the mobile frame 11 by welding, bonding, etc. The electric connector 15 can adopt an aviation plug with good waterproof performance, and the terminal head 30 can be an aviation plug. The mobile frame 11 is also provided with a plug-in device 16 for installing the camera device 3; when the quick-connect connector 14 is plugged in with the spray gun 2 for spraying, the plug-in device 16 is in a state of not being connected to the camera device 3.

[0027] Specifically, the plug-in device 16 includes a plug-in seat 161, a plug-in hole 162 is provided on the plug-in seat 161, and a limiting groove 163 is provided on the hole wall of the plug-in hole 162. Correspondingly, the camera device 3 includes a camera 31 and a camera bracket 32 ​​for mounting the camera 31. The camera bracket 32 ​​is provided with a plug-in head 33 that cooperates with the plug-in hole 162, and the plug-in head 33 is provided with a limiting portion 34 that cooperates with the limiting groove 163. The plug-in seat 161 is a plastic structure, and its plastic deformation can provide a prerequisite for the plug-in head 33 to be inserted into the plug-in hole 162. When the plug-in head 33 is inserted into the plug-in hole 162, the limiting portion 34 is stuck in the limiting groove 163.

[0028] The steel pipe PT detection frame of the present invention is provided with a quick-plug connector 14 and an electrical connector 15. When the steel pipe detection is required, the spray gun 2 is plugged into the quick-plug connector 14. At this time, the plug-in device 16 is not connected to the camera device 3. An external force is applied to move the mobile frame 11 in the steel pipe. The spray gun 2 sprays the penetrant to the steel pipe when the mobile frame 11 moves. After the spraying is completed, wait for a period of time, and after cleaning the excess penetrant, spray the developer, and then the mobile frame 11 is moved. 11 is withdrawn from the steel pipe, the camera device 3 is plugged into the plug-in device 16, and the terminal 30 of the camera device 3 is plugged into the electrical connector 15. As for the spray gun 2, it can be unplugged from the mobile frame 11 or retained on the mobile frame 11. The steel pipe PT detection frame realizes plug-and-play during detection. When the spray gun 2 is plugged into the quick-connect connector 14, the plug-in device 16 is in a state of not being connected to the camera device 3, preventing the spray liquid sprayed from the spray gun from covering the camera device 3.

[0029] Furthermore, the electrical connector 15 passes through the bottom of the plug-in hole 162 and extends into the plug-in hole 162. The bottom of the plug-in hole 162 is provided with a through hole 1621 for the electrical connector 15 to pass through; the wiring head 30 is arranged in the plug-in head 33, and the plug-in head 33 is provided with a mounting groove 331 for mounting the wiring head 30. The wire 301 on the wiring head 30 passes through the plug-in head 33, and the wiring head 30 is partially exposed from the mounting groove 331. When the camera device 3 is plugged into the plug-in device 16, the wiring head 30 of the camera device 3 is simultaneously plugged into the electrical connector 15. The operation is simple and can be completed in one step.

[0030] Furthermore, the movable frame 11 is also provided with a positioning column socket 17, and the spray gun 2 is provided with a positioning column 21 that cooperates with the positioning column socket 17. The dual limiting effect of the positioning column socket 17 and the quick-connect connector 14 on the spray gun 2 can ensure the connection stability of the spray gun 2 and the spraying effect. The insertion direction of the spray gun 2 when it is plugged into the quick-connect connector 14 is the same as the direction in which the positioning column 21 is inserted into the positioning column socket 17, and when the spray gun 2 is inserted into the quick-connect connector 14, the positioning column 21 is simultaneously inserted into the positioning column socket 17, so that the spray gun 2 is convenient to plug in and plug in quickly.

[0031] In the prior art, when cleaning excess penetrant from a steel pipe, the cleaning spray gun 4 is generally directly held by hand, which requires a large amount of manual participation and is inefficient. Therefore, in this embodiment, the PT detection device also includes a pipeline 18 connected to the cleaning liquid container and arranged on the mobile frame 11. A hydraulic pump and other accessories can be arranged on the pipeline 18, and the cleaning liquid is extracted by the hydraulic pump. A quick-connector 19 that can be plugged into the cleaning spray gun 4 is arranged on the pipeline 18. When cleaning is required, the cleaning spray gun 4 is plugged into the quick-connector 19, the hydraulic pump is turned on, and the mobile frame 11 moves in the steel pipe. Thereafter, there is less manual participation for a period of time, and the work efficiency is high. Furthermore, when the quick-connector 19 is plugged into the cleaning spray gun 4 for cleaning, the plug-in device 16 is in a state of not being connected to the camera device 3, effectively preventing the cleaning liquid sprayed by the cleaning spray gun 4 from being sprayed onto the camera device 3, and there is no additional operation of wiping the cleaning liquid on the camera device 3, which is beneficial to the service life of the camera device 3 and the steel pipe detection efficiency.

[0032] The movable frame 11 is also provided with a second positioning column socket 101, and the cleaning spray gun 4 is provided with a second positioning column 41 that cooperates with the second positioning column socket 101. The dual limiting effect of the second positioning column socket 101 and the second quick-plug connector 19 on the cleaning spray gun 4 can ensure the connection stability of the cleaning spray gun 4 and ensure the cleaning effect. The insertion direction of the cleaning spray gun 4 when it is plugged into the second quick-plug connector 19 is the same as the direction in which the positioning column 41 is inserted into the second positioning column socket 101, and when the cleaning spray gun 4 is inserted into the second quick-plug connector 19, the positioning column 41 is simultaneously inserted into the second positioning column socket 101, so that the cleaning spray gun 4 is easy to plug in and plug in quickly.

[0033] Since the quick-connect connector 14 on the pipeline 12 and the quick-connect connector 2 19 on the pipeline 2 18 involve frequent plugging and unplugging actions, the quick-connect connector 14 and the quick-connect connector 2 19 are prone to problems. When any of them has problems, the entire steel pipe PT detection frame will not be able to be used. For this reason, Figure 5As shown, the pipeline 12 is provided with a switch valve 1 51 and a switch valve 2 52, the pipeline 2 18 is provided with a switch valve 3 53 and a switch valve 4 54, the pipeline 12 and the pipeline 2 18 are connected and communicated through pipeline 3, the pipeline 3 is provided with a switch valve 55, the connection point between the pipeline 3 and the pipeline 12 is located between the switch valve 1 51 and the switch valve 2 52, and the connection point between the pipeline 3 and the pipeline 2 18 is located between the switch valve 3 53 and the switch valve 4 54; the structures of the quick connector 14 and the quick connector 2 19 are the same.

[0034] Under normal circumstances, that is, when the quick-insert connector 14 and the quick-insert connector 2 19 can be used normally, the switch valve 55 is in a closed state, the pipeline 3 is in a blocked state, and the switch valve 1 51 and the switch valve 2 52 on the pipeline 12 are both in an open state, the pipeline 12 is in a conducting state, the switch valve 3 53 and the switch valve 4 54 on the pipeline 2 18 are both in an open state, and the pipeline 2 18 is in a conducting state; when the quick-insert connector 14 is damaged, if you want to spray, close the switch valve 1 51 and the switch valve 4 54, open the switch valve 2 52, the switch valve 3 53, and the switch valve 5 55, and spray The coating spray gun 2 is plugged into the quick connector 19. If you want to do the cleaning work, open the switch valve 3 53 and the switch valve 4 54, close the switch valve 5 55, and plug the cleaning spray gun 4 into the quick connector 19. When the quick connector 19 is damaged, if you want to do the spraying work, open the switch valve 1 51 and the switch valve 2 52, close the switch valve 5 55, and plug the coating spray gun 2 into the quick connector 1 14. If you want to do the cleaning work, open the switch valve 1 51, the switch valve 4 54, and the switch valve 55, close the switch valve 2 52 and the switch valve 3 53, and plug the cleaning spray gun 4 into the quick connector 1 14. It can be seen that as long as any one of the quick connector 1 14 and the quick connector 2 19 can work, the worker only needs to operate the relevant valves to enable the entire steel pipe PT detection frame to be plugged into the relevant components for detection, ensuring that the steel pipe PT detection frame can be used continuously and ensuring the detection efficiency.
