DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0024] Reference Figure 1-Figure 5 A handheld pressure vessel weld defect detection device comprises a bracket 1, a line laser module 2 and a laser radar sensor module 3 are fixedly mounted on the surface of the bracket 1, a mounting port 4 is provided on the back of the bracket 1, a tablet computer 5 is provided in the mounting port 4, a through opening 12 is provided on the surface of the bracket 1, and the through opening 12 corresponds to the position of a camera provided in the tablet computer 5 (the line laser module 2 and the laser radar sensor module 3 are both disclosed in the Chinese patent with publication number CN218411062U, which are prior arts and are not described in detail herein);

[0025] The upper surface of the bracket 1 is symmetrically provided with two through-holes, in which a plug rod 6 is slidably inserted, and a clamping block 7 and a mounting block 8 are fixedly installed at the bottom and top of the plug rod 6, respectively. The plug rod 6 is connected to the bracket 1 through a telescopic component, and the telescopic component includes a telescopic spring 9 sleeved on the plug rod 6, and the two ends of the telescopic spring 9 are fixedly connected to the mounting block 8 and the bracket 1, respectively, and the inner wall of the clamping block 7 and the wall of the mounting opening 4 are provided with a rubber layer;

[0026] When it is necessary to install the tablet computer 5, firstly, the two insertion rods 6 are controlled to move upward together, and then the tablet computer 5 is placed in the installation opening 4, and the positions of the tablet computer 5 and the two card blocks 7 are made to correspond, and then the two insertion rods 6 are loosened, and the two insertion rods 6 will quickly move downward and reset under the elastic potential energy of the telescopic springs 9, and then the two card blocks 7 will both clamp the tablet computer 5 and fix it in the installation opening 4. When it is necessary to disassemble, it is only necessary to control the two insertion rods 6 to move upward to separate the two card blocks 7 from the tablet computer 5, which is convenient and quick.

[0027] A telescopic rod 10 is vertically fixedly installed on the upper surface of the bracket 1, and a V-shaped frame 11 is fixedly installed on the top of the telescopic rod 10. The two ends of the V-shaped frame 11 are respectively fixedly connected to two mounting blocks 8. By pulling the V-shaped frame 11 upward, the two insertion rods 6 can be controlled to move upward together, which is convenient and quick, and there is no need to control the two insertion rods 6 to move upward one by one.

[0028] A support assembly is provided on the surface of the bracket 1, and the support assembly is used to determine the relative position of the bracket 1 and the pressure vessel. The support assembly includes a symmetrically arranged hollow rod 13 with one end being a closed design. The closed end of the hollow rod 13 is fixedly connected to the bracket 1 through a connecting rod 14. A suction cup 15 is fixedly installed on the open end of the hollow rod 13. An air port 16 is provided on the surface of the hollow rod 13. A socket is provided on the closed end of the hollow rod 13. A rotating rod 17 is inserted in the socket for rotation and sealing. The end of the rotating rod 17 located outside is rotatably connected to the surface of the bracket 1. , a covering plate 18 for covering the air port 16 is fixedly installed at one end of the hollow rod 13 through a connecting rod, and the two rotating rods 17 are both controlled to rotate through a transmission assembly, and the transmission assembly includes two gears 19 respectively fixedly sleeved on the two rotating rods 17 and two rack rods 20 respectively meshing with the two gears 19, and a connecting plate 21 is fixedly installed on the top of the two rack rods 20, and a rectangular plate is fixedly installed on the surface of the bracket 1, and a spring rod 22 is fixedly installed on the surface of the rectangular plate, and the top of the spring rod 22 is fixedly connected to the lower surface of the connecting plate 21;

[0029] When measuring, it is necessary to place the suction cup 15 in the support assembly against the surface of the pressure vessel to determine the relative position of the bracket 1 and the pressure vessel. First, the connecting plate 21 is controlled to move downward, and then the multiple rack rods 20 will also move downward. The two gears 19 respectively meshing with the two rack rods 20 will rotate with the two rotating rods 17, so that the two covering plates 18 no longer cover the two air ports 16 respectively. At this time, the suction cup 15 is pressed against the surface of the pressure vessel to determine the relative position. Since the air port 16 is not covered, the suction cup 15 will not be adsorbed when it is pressed against the pressure vessel. When the appropriate relative position is found, it is released. The connecting plate 21 will move up and reset with the two rack rods 20 under the elastic potential energy of the spring rod 22, and then the two rotating rods 17 will also rotate and reset with the two covering plates 18 respectively. At this time, the two covering plates 18 will cover the two gas ports 16 respectively. At this time, when the suction cup 15 abuts against the surface of the pressure vessel, the gas in the hollow rod 13 will slip out from the gap between the suction cup 15 and the contact surface of the pressure vessel, thereby completing the adsorption, without having to hold the device all the time, and at the same time, it can also avoid the defect that the control support assembly abuts against the pressure vessel and the abutting position is accidentally offset due to holding the device for a long time;

[0030] When the adsorption needs to be released, the connecting plate 21 is controlled to move downward, the two covering plates 18 are controlled to rotate and no longer cover the two gas ports 16. At this time, the external gas will enter the hollow rod 13 from the gas ports 16, thereby releasing the adsorption.

[0031] In the utility model, when it is necessary to install the tablet computer 5, firstly, the two insertion rods 6 are controlled to move upward together, and then the tablet computer 5 is placed in the installation opening 4, and the positions of the tablet computer 5 and the two clamping blocks 7 are made to correspond, and then the two insertion rods 6 are loosened, and the two insertion rods 6 will quickly move downward and reset under the elastic potential energy of the telescopic component, and then the two clamping blocks 7 will clamp the tablet computer 5 and fix it in the installation opening 4. When it is necessary to disassemble, it is only necessary to control the two insertion rods 6 to move upward to separate the two clamping blocks 7 from the tablet computer 5. It is convenient and quick, avoids the cumbersome steps of using screw and nut fixings, and improves the work efficiency of disassembling and assembling the tablet computer 5.

[0032] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
