[0038] When in use, put the metal plate 10 to be detected into the fixed base 1, move the detection ear 9 to be lifted and detected to the bottom of the lifting plate 7, and move the lifting rod 13 so that the end of the lifting rod 13 away from the installation sleeve 12 is separated from the lifting cross bar 22. At this time, the installation sleeve 12 rotates downward under the gravity of the lifting rod 13, that is, the lifting rod 13 is tilted downward, and the lifting rod 13 is moved to penetrate the detection ear 9, and then the limit movable plate 18 is pressed downward. The limit rod 17 and the connecting rod 16 are staggered and pressed until the limit rod 17 is away from the installation sleeve 12. One end moves to the bottom of the lifting rod 13, at this time, the lifting cross bar 22 is moved between the connecting rod 16 and the limiting rod 17, and after the limiting movable plate 18 is loosened, the limiting movable plate 18 and the limiting rod 17 are flipped upward under the elastic action of the connecting spring 14. At this time, the end of the limiting rod 17 away from the mounting sleeve 12 is covered at the bottom of the lifting cross bar 22, that is, the lifting cross bar 22 is stuck in the connecting hole 29 by the limiting rod 17 and the connecting rod 16, completing the assembly of the lifting rod 13. In the process of lifting the detection ear 9, the connecting spring 14 always gives the limiting movable plate 18 an upward force. Thrust, to ensure that one end of the limit rod 17 is always against the bottom of the lifting cross bar 22, effectively preventing the lifting cross bar 22 from falling off from the connecting hole 29, and improving the detection safety; the lifting plate 7 is pulled upward by the hydraulic cylinder 6, and then the lifting assembly 26 is lifted upward by the steel cable 8, and the detection ear 9 is pulled for detection. The tension sensor 27 records the tension on the detection ear 9 and the tension value when the detection ear 9 falls off from the metal plate 10 to be detected, and the two tension sensors 27 detect the tension of the two steel cables 8 respectively. When the two tension sensors 27 detect When the tension values ​​are consistent, it means that the detection ear 9 is centrally set on the lifting rod 13. If the tension values ​​detected by the two tension sensors 27 are inconsistent, it means that the position offset of the detection ear 9 needs to be adjusted to ensure the accuracy of the detection. After the detection is completed, push the metal plate 10 to be detected to move in the fixed base 1, move the next detection ear 9 to be detected to the bottom of the lifting plate 7, and then press the limit movable plate 18 downward, so that the limit rod 17 and the connecting rod 16 clamp one end of the lifting cross bar 22 and separate from each other, and take the lifting cross bar 22 out of the connecting hole 29, which is convenient and easy to operate.

[0039] As a preferred embodiment of the present invention, the limiting rod 17 and the connecting rod 16 are both provided with a positioning wing 19 at one end away from the mounting sleeve 12, and a threaded hole is opened on the side of the positioning wing 19, and a positioning bolt 20 is penetrated through the threaded hole. After the lifting cross bar 22 is stuck in the connecting hole 29, the positioning bolt 20 can be inserted into the threaded hole to further tighten the limiting rod 17 and the connecting rod 16 to prevent the lifting cross bar 22 from falling off from the connecting hole 29.

[0040] As a preferred embodiment of the present invention, anti-slip protrusions 15 are provided on the opposite sides of the lifting rod 13 and the limiting movable plate 18, which are used to prevent the detection ear 9 from slipping, and when the detection ear 9 is separated from the metal plate 10 to be detected, protection is provided between the detection ear 9 and the lifting rod 13 and between the detection ear 9 and the limiting movable plate 18 to avoid a hard collision between the detection ear 9 and the lifting rod 13 and the limiting movable plate 18, thereby avoiding damage to the lifting rod 13 and the limiting movable plate 18.

[0041] As a preferred embodiment of the present invention, both ends of the lifting cross bar 1 21 and the lifting cross bar 2 22 are provided with limiting components 23 for limiting the steel cable 8 .

[0042] As a preferred embodiment of the present invention, both inner walls of the fixed base 1 are provided with placement plates 4 for supporting the bottoms of both sides of the metal plate 10 to be inspected.

[0043] As a preferred embodiment of the present invention, positioning mechanisms 11 are provided on both sides of the interior of the fixed base 1 for pressing and positioning the metal plate 10 to be inspected during lifting inspection.

[0044] As a preferred embodiment of the present invention, the positioning mechanism 11 includes a through hole 113 opened on the placement plate 4, and a telescopic component 111 is installed on the bottom inner wall of the fixed base 1. A pressing component 112 is installed at one end of the piston rod of the telescopic component 111. The position of the pressing component 112 corresponds to the opening position of the through hole 113. During detection, the telescopic component 111 pushes the pressing component 112 to move upward, and the pressing component 112 moves to the top of the placement plate 4 through the through hole 113 to press and fix the two side edges of the metal plate 10 to be detected.

[0046] As a preferred embodiment of the present invention, a reinforcing plate 3 is installed at the bottom of the metal plate 10 to be inspected, and the two side edges of the reinforcing plate 3 extend to the bottom of the placement plate 4 to reinforce the middle position of the metal plate 10 to be inspected, thereby preventing the middle position of the metal plate 10 to be inspected from bulging upward and deforming when the detection lug 9 is lifted for inspection.

[0047] Example 2, reference Figure 10 to Figure 11The difference between a metal plate welding strength detection device and Example 1 is that a protective airbag 24 is arranged at the bottom of the lifting plate 7, and an air pump 25 is installed on the lifting plate 7. The air outlet end of the air pump 25 is connected with the interior of the protective airbag 24 through an extended air pipe. During the detection process, the protective airbag 24 can be inflated by the air pump 25. The protective airbag 24 is inflated and expands and presses the top of the limiting movable plate 18 to limit the position, so as to avoid the situation that the limiting movable plate 18 hits the bottom of the lifting plate 7 under the action of inertia at the moment when the detection ear 9 is separated from the metal plate 10 to be detected.
