[0012] Beneficial effects

[0013] This invention provides a device for inspecting the inner diameter of pipes. Compared with existing technologies, it has the following advantages:

[0014] (1) The device for checking the inner diameter of the pipe has a test platform installed inside the device box, and a placement slot is opened on the top of the test platform. An installation frame, a second electric telescopic rod and a first electric telescopic rod are installed on the inner side of the placement slot. The cooperation of these two structures can double clamp the pipe inside and outside when pressing different pipes, ensuring the stability during the test. At the same time, the first motor at the bottom can drive the pipe to rotate under the action of the ball, which facilitates a more comprehensive observation and improves the practicality of the equipment.

[0015] (2) The device for checking the inner diameter of the pipe is equipped with an explosion-proof cylinder connected to a hydraulic rod inside the device box. When the explosion-proof cylinder covers the pipe, the measuring frame and spotlight can be inserted into the pipe. The two measuring rods can measure the length, and when the spotlight is turned on, the staff can observe whether there are cracks in the pipe surface and light transmission through the external tempered glass strip. This makes it convenient for the staff to use and also greatly improves the quality of the product.

[0016] (3) The device for checking the inner diameter of the pipe has an air bladder installed on the surface of a square threaded cylinder and is connected to an external fan through an air guide pipe and an air delivery pipe. When the fan is started, the air bladder can be inflated, thereby applying pressure to the inner wall of the pipe, which facilitates the detection of the pressure-bearing capacity of the pipe material. This can indirectly reduce production losses for the manufacturer and improve the overall functionality of the equipment. Attached Figure Description

[0031] In order to perform pressure tests on the inside of the pipe, in this invention, an anti-slip ring 30 is fixedly connected to the surface of the square threaded cylinder 20 and below the sealing cover 28.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] In use, open the sliding door on the surface of the device box 2, and then place the pipe inside the placement slot 4. When the bottom end of the pipe presses against the top of the pressing block 10, the pressing block 10 will descend and trigger the button 12. At this time, the first electric telescopic rod 15 and the second electric telescopic rod 18 respectively push the ball bearing 19 and the limiting plate 16 to clamp the pipe from both the outside and inside. Then, the second motor 39 starts, driving the threaded rod 22 to rotate, causing the square threaded cylinder 20 to push the measuring frame 32 into the pipe. The measuring rods 33 on both sides of the measuring frame 32 will automatically retract and adjust when they encounter the pipe. The operator can determine the inner diameter length through the scale on the surface of the measuring rod 33. Then, the operator starts the hydraulic rod 23 to drive the explosion-proof cylinder 25 to descend and cover the pipe. Then, the second motor 39 continues to start, causing the square threaded cylinder to descend. As the cylinder 20 continues to descend, the sealing cap 28 will cover the top of the pipe through the opening 26. When the square threaded cylinder 20 continues to descend, the sealing cap 28 will be firmly pressed against the top of the pipe by the action of the high-pressure spring 29. At this time, the airbag 31, measuring frame 32 and spotlight 35 are all inside the pipe. At this time, the spotlight 35 is turned on, and the strong light of the spotlight 35 will illuminate the inside of the pipe. At this time, the first motor 6 starts, and the pipe is rotated by the rotating rod 7. The staff can observe whether there are light-transmitting points on the surface of the pipe through the tempered glass strip 40 to find whether there are any damaged points on the inner diameter. After the crack detection is completed, the blower 36 can be started. Through the action of the air guide pipe 37 and the air supply pipe 38, the gas is injected into the inside of the airbag 31. The airbag 31 inflates and squeezes the inner wall of the pipe to test its pressure resistance.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
