[0032] The limiting groove 104 and the top limiting groove 204 cooperate to limit the upper and lower ends of the stainless steel plate, and the stainless steel plate is transported by the rotation of the driving roller 102 .

[0033] Through the above technical solution, the transmission roller 102 at the bottom and the top limit groove 204 at the top are provided to support the stainless steel plate, and the limit groove 104 and the top limit groove 204 are used to limit the stainless steel plate, so that the stainless steel plate can be transmitted standing up. During the transmission of the stainless steel plate, the outer surface of the stainless steel plate is detected by the detection terminals 303 on both sides, and there is no need to turn the stainless steel plate over, thereby improving the efficiency of detecting surface defects of the stainless steel plate.

[0034] Specifically, the driving roller 102 and the top supporting roller 203 are symmetrical in vertical direction, and the limiting groove 104 and the top limiting groove 204 are located on the same line.

[0035] Through the above technical solution, the transmission rollers 102 and the top support rollers 203 symmetrically arranged up and down can convey the stainless steel plate more stably, and the positions of the limit grooves 104 and the top limit grooves 204 are set to keep the stainless steel plate as vertical as possible during the conveying process.

[0036] Specifically, a suspension frame 106 is fixedly connected to the inner top of the observation port 105 , and a traction rod 107 is fixedly connected to the interior of the suspension frame 106 .

[0037] Through the above technical solution, the provided suspension frame 106 is used to install the traction rod 107, and the traction rod 107 is used to support and limit the floating frame 201, thereby ensuring that the floating frame 201 can remain horizontal and stable when it is raised or lowered.

[0038] Specifically, sliding blocks 202 are fixedly connected to both sides of the floating frame 201. The sliding blocks 202 extend to the interior of the suspension frame 106 and are penetrated by the traction rod 107. An elastic member 205 is installed on the top of the sliding block 202 and is sleeved on the surface of the traction rod 107.

[0044] Specifically, the detection terminal 303 is a visual detection terminal or a sonar detection terminal.

[0045] Through the above technical solution, if a visual inspection terminal is used, the cost is low and it can detect obvious defects on the outer surface of the stainless steel plate. If a sonar inspection terminal is used, it is necessary to bring the sonar inspection terminal close to the stainless steel plate so that it can be used to detect hidden defects.
