[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figures 1-4 As shown, the utility model provides a pressure vessel flaw detection device, including a flaw detection head 1 and a controller 2. The flaw detection head 1 is externally provided with a support base 4, a guide plate 6, a receiving mechanism 7, and a placement mechanism 3. The guide plate 6 is rotatably connected to the upper part of the support base 4 through an ear plate and a shaft. The controller 2 is mounted on one end of the support base 4, and the placement mechanism 3 is located on one side of the support base 4. The flaw detection head 1 and the controller 2 are both prior art, wherein the controller 2 can operate other motors.

[0029] A guide rail groove 61 is provided on the inner side of the guide plate 6, and the guide plate 6 is used to cooperate with the receiving mechanism 7;

[0030] The receiving mechanism 7 includes a mounting frame 71, a plug-in block 75 and a connecting rod 77. The plug-in block 75 is inserted into the guide rail groove 61. One side of the mounting frame 71 is used to install the flaw detection head 1. The receiving mechanism 7 cooperates with the guide plate 6 to move the position of the flaw detection head 1.

[0031] The placement mechanism 3 includes a base plate 31 and a positioning roller 33. A servo motor 36 is installed at one end of the base plate 31. The positioning roller 33 is used to drive the container to rotate. The placement mechanism 3 is used to adjust the distance between the two positioning rollers 33 to adapt to pressure vessels of different diameters.

[0032] In a further embodiment, one end of the plug-in block 75 is fixedly connected to the side of the mounting frame 71 away from the flaw detection head 1, and the end of the plug-in block 75 located inside the guide rail groove 61 is rotatably connected to the linkage wheel 76, and driving wheels 74 are provided on the upper and lower parts of the plug-in block 75.

[0033] In this embodiment, a groove is formed at one end of the plug-in block 75 , and the linkage wheel 76 is rotatably connected in the groove, and the linkage wheel 76 is tightly fitted with the inner wall of the guide rail groove 61 .

[0034] In a further embodiment, a stepper motor 72 is installed at the bottom of the mounting frame 71, and an output shaft 73 is installed at the output end of the stepper motor 72. The output shaft 73 passes through a fixed driving wheel 74, the driving wheel 74 is attached to the inner side of the guide plate 6, and the output shaft 73 passes through the plug-in block 75.

[0035] In this embodiment, the installation location of the stepping motor 72 is located outside the guide plate 6 , so it does not affect the overall movement of the receiving mechanism 7 .

[0036] In a further embodiment, one end of the connecting rod 77 is rotatably connected to the mounting frame 71, and the other end of the connecting rod 77 is rotatably connected to the auxiliary wheel 78. A damping member 79 is provided at the connecting rod 77 of the mounting frame 71, and the output end of the damping member 79 is connected to one side of the connecting rod 77, and the auxiliary wheel 78 is attached to the inner side of the guide plate 6.

[0037] In this embodiment, when the stepper motor 72 is operating, it will drive the driving wheel 74 to rotate. There is friction between the driving wheel 74 and the guide plate 6, so that the entire receiving mechanism 7 can move within the limited range of the guide rail groove 61; there are four connecting rods 77, which are respectively located near the four top corners where the plug-in block 75 connects to the mounting frame 71.

[0038] In a further embodiment, symmetrical sliding grooves 37 are opened above the two ends of the bottom plate 31, and the interior of the sliding grooves 37 is slidably connected to a portion of the sliding blocks 34. The sliding blocks 34 are located at both ends of the positioning roller 33, and a driving motor 38 is installed on one side of one of the sliding blocks 34.

[0039] In this embodiment, the damping member 79 is a damping rod in the prior art, so that the auxiliary wheel 78 is always in contact with the inner side of the guide plate 6, so that when the receiving mechanism 7 moves as a whole to the bending part of the guide plate 6, it can still maintain a certain distance from the pressure vessel placed above the bottom plate 31; the guide plate 6 is U-shaped as a whole, so when the receiving mechanism 7 moves with the flaw detection head 1, it can reach the end of the pressure vessel.

[0040] In a further embodiment, two receiving rollers 32 are rotatably connected to the top of the base plate 31, and a bidirectional screw 35 is rotatably connected to the inside of the base plate 31. Both ends of the bidirectional screw 35 pass through the threaded connection sliding block 34 located in the slide groove 37, and the bidirectional screw 35 is installed at the output end of the servo motor 36.

[0041] In this embodiment, the receiving roller 32 is used to receive the pressure vessel, and when the pressure vessel is placed between the two receiving rollers 32, the bidirectional screw 35 can be rotated by driving the servo motor 36, thereby causing the two positioning rollers 33 to move toward the middle and fit the outer wall of the pressure vessel. At this time, the operation of the drive motor 38 will cause the pressure vessel to rotate passively, so that it can be detected by the flaw detection head 1 during the movement.

[0042] In a further embodiment, one side of the support base 4 is rotatably connected to a hydraulic cylinder 5 , and an output end of the hydraulic cylinder 5 is rotatably connected to a guide plate 6 .

[0043] In this embodiment, when the guide plate 6 is parallel to the support seat 4, the guide plate 6 is located above the support seat 4, and at this time the output end of the hydraulic cylinder 5 is in an extended state. On the contrary, when the output end of the hydraulic cylinder 5 contracts, the guide plate 6 will be perpendicular to the support seat 4, and then parallel to the placement mechanism 3.

[0044] The working principle of this utility model is as follows:

[0045] When the hydraulic cylinder 5 is operated by the controller 2, the guide plate 6 can be rotated from above the support base 4 to above the bottom plate 31 and parallel to the bottom plate 31. At this time, the stepping motor 72 is operated by the controller 2, so that the output shaft 73 rotates with the driving wheel 74. Since the driving wheel 74 is in contact with the inner side of the guide plate 6, the mounting frame 71 moves with the installed flaw detection head 1 within the guide range of the guide rail groove 61. During the movement, the controller 2 will operate the flaw detection head 1, thereby enabling the container placed above the bottom plate 31 to be inspected, and the two ends of the container can be inspected, thereby increasing the flaw detection range.

[0046] The controller 2 can be used to operate the servo motor 36 so that the slide block 34 brings the two positioning rollers 33 closer to each other, so that containers of different diameters can be placed. In combination with the receiving mechanism 7 and the controller 2, the applicable range of flaw detection can be improved.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
