DETAILED DESCRIPTION

[0022] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0023] Example 1: See Figure 1 and Figure 4, a boiler pressure vessel inspection and detection device of the present embodiment includes a support seat 10, a positioning frame 20 and a detection frame 30. The top of the support seat 10 is rotatably provided with a rotating disk 11, which is driven to rotate and rotate to an approximate detection position. The positioning frame 20 is fixedly installed with the top of the rotating disk 11, and the top of the positioning frame 20 is fixedly installed with a support frame 21, and the bottom of the support frame 21 is fixedly installed with a support column 22, and the surface of the support column 22 is slidably connected with a lifting plate 23, and the bottom of the support frame 21 is fixedly installed with a positioning spring 24. After the detection is completed, the lifting plate 23 is driven to move upward under the restoring force of the positioning spring 24, and the bottom of the positioning spring 24 is fixedly installed with the lifting plate 23, and the bottom of the lifting plate 23 is fixedly connected with a positioning convex head 25, and the top of the rotating disk 11 is penetrated with a through groove 12, and the positioning convex head 25 is slidably connected with the inside of the through groove 12, and the top of the support seat 10 is provided with a positioning groove 13, and the completion After the inspection, the lifting plate 23 drives the positioning protrusion 25 to move upward and separate from the positioning groove 13 under the restoring force of the positioning spring 24; when the inspection is performed, pressure is applied, and when the positioning protrusion 25 moves downward, it passes through the through groove 12 and enters the positioning groove 13, contacts the inclined side wall of the positioning groove 13, and continues to apply pressure to the pressure vessel, and the positioning protrusion 25 abuts against the inside of the positioning groove 13, so that the positioning protrusion 25 slides along the side wall of the positioning groove 13, and finally makes the positioning protrusion 25 coaxial with the positioning groove 13. At this time, the positioning protrusion 25 fits with the positioning groove 13 and completely enters the positioning groove 13, so that the pressure vessel is in the inspection position during the inspection, and the positioning of the pressure vessel is completed. A placement rack 26 is provided on the top of the positioning protrusion 25, and the pressure vessel is placed in the placement rack 26. When the pressure vessel in the placement rack 26 is inspected, the pressure vessel drives the placement rack 26 to move downward, and the placement rack 26 moves downward to drive the lifting plate 23 and the positioning protrusion 25 to move downward.

[0024] See also Figure 4 A slot 27 is provided on the top of the lifting plate 23 and the positioning boss 25. Since the sizes of pressure vessels to be produced in different batches are different, a placement rack 26 that is adapted to the size of the pressure vessel to be tested is inserted into the slot 27 through a mounting ring 28. A mounting ring 28 is fixedly installed on the bottom of the placement rack 26. The mounting ring 28 is plugged into the inside of the slot 27. A threaded hole 29 is provided on the surface of the mounting ring 28 and the positioning boss 25. The threaded hole 29 is aligned, and then a screw is screwed into the threaded hole 29 to fix the placement rack 26. This enables the device to adapt to the detection of pressure vessels of different sizes and improves the practicability of the device.

[0025] See also Figure 1-4A cross frame 31 is movably provided on the top of the detection frame 30, a locking pin cover 32 is provided at the bottom of the cross frame 31, a locking pin 33 is slidably provided inside the locking pin cover 32, and locking pin grooves 34 are equidistantly provided on the surface of the detection frame 30. The locking pin 33 is plugged into the inside of the locking pin groove 34. The locking pin 33 is pulled to disengage from the locking pin groove 34. At this time, the cross frame 31 can move up and down, and the height of the cross frame 31 is adjusted up and down. After adjusting to a suitable position, the locking pin 33 is reinserted into the locking pin groove 34.

[0026] See also Figure 1-4 An electric push rod 40 and an air pump 41 are fixedly installed on the top of the cross frame 31. The height of the cross frame 31 is adjusted up and down. The cross frame 31 drives the electric push rod 40 to move up and down, and then adjusts the height of the electric push rod 40, so that the electric push rod 40 can be used to detect pressure vessels of different heights, so that the detection can be adjusted in accordance with the height of the pressure vessel, to avoid the height of the electric push rod 40 hindering the detection of the pressure vessel. A sealing disk 42 is installed at the bottom of the cross frame 31 through the output end of the electric push rod 40. A stamping tube 43 and a detection tube 44 are fixedly installed on one side of the air pump 41. One end of the stamping tube 43 and the detection tube 44 are installed with the sealing disk 42. A pressure gauge 45 is provided on one side of the air pump 41. Start the electric push rod 40, and the electric push rod 40 drives the sealing disk 42 to move downward. When the sealing disk 42 contacts the pressure vessel, it drives the pressure vessel to move downward.

[0027] See also Figure 1-4 A positioning block 35 is fixedly installed inside the lock pin cover 32, and a return spring 36 is fixedly installed on one side of the positioning block 35. A spring groove 37 is provided inside the lock pin 33, and one end of the return spring 36 is fixedly installed with the inner wall of the spring groove 37. In a natural state, the thrust of the return spring 36 pushes the inner wall of the spring groove 37 so that the lock pin 33 has a thrust toward the lock pin groove 34, thereby preventing the cross frame 31 from vibrating due to the start and stop of the electric push rod 40, and further preventing the lock pin 33 from being separated from the lock pin groove 34 due to the vibration of the cross frame 31.

When the pressure vessel in the placement rack 26 is detected, the pressure vessel drives the placement rack 26 to move downward, and the placement rack 26 moves downward to drive the lifting plate 23 and the positioning convex head 25 to move downward. When the positioning convex head 25 moves downward, it enters the positioning groove 13 and contacts the inclined side wall of the positioning groove 13. Continue to apply pressure to the pressure vessel to make the positioning convex head 25 slide along the side wall of the positioning groove 13, and finally make the positioning convex head 25 coaxial with the positioning groove 13. At this time, the positioning convex head 25 fits with the positioning groove 13 and completely enters the positioning groove 13, so that the pressure vessel is in the detection position during detection, and the positioning of the pressure vessel is completed. The positioning of the pressure vessel is avoided to avoid the decrease in accuracy after the motor is turned over due to long-term use. At the same time, it also reduces the demand for motor rotation accuracy and avoids the phenomenon of misalignment between the sealing disk and the pressure vessel.
