[0024] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. The following is in conjunction with Figures 1-7 , and a further detailed description of the preferred embodiments of the present invention will be given: A steel corrosion detection device, as Figures 1-7 shown, includes a frame 1. A transmission device 2 for conveying steel and an information collection device 3 for collecting information are provided on the frame 1. The transmission device 2 includes a pair of conveyors 201. A bracket device 202 is provided on the back side of the conveyor 201. The angle transformation of the conveyor 201 is controlled. The information collection device 3 includes a support system and a photographing device 302. The support system includes a support plate 301 and a cylinder 304. The cylinder 304 is arranged on the frame 1 through the support plate 301. The photographing device 302 is arranged on the cylinder 304 and is used for collecting steel information.

[0025] In order to adjust the angle between the two conveyors 201, the following technical solution is adopted in this device: The bottom ends of the pair of conveyors 201 are hinged and fixed to the top of the frame 1. The bracket device 202 includes a piston box 2021 and a piston rod 2022. The top end of the piston rod 2022 is movably connected to the conveyor 201, and the connection method can be hinged. The rod body of the piston rod 2022 is arranged inside the piston box 2021 and is slidably connected to the piston box 2021. A sealing structure is arranged at the end of the piston rod 2022 arranged inside the piston box 2021 to ensure the airtightness of the gas inside the piston box 2021. Rotating wheels 2023 are arranged on the side of the outer end of the bottom of the piston box 2021 in pairs. The rotating wheels 2023 are connected to the top plate of the frame 1. The bottom of the piston box 2021 is connected with an auxiliary component one 4 to facilitate the operation of the bracket device 202. Multiple bracket devices 202 can be arranged on each conveyor 201; The auxiliary component one 4 includes an electric device 401, a box body 402 and a connecting pipe 403. A through groove is arranged on the side of the box body 402. One end of the through groove is connected to the connecting pipe 403. The pipe body of the connecting pipe 403 is connected to the piston box 2021 through a hose 404. An electric device 401 is arranged on the top of the box body 402. The output shaft of the electric device 401 is connected with a threaded rod 405. The threaded rod 405 is connected with an auxiliary component two 5. The other end of the through groove of the box body 402 is connected to the threaded rod 405 through a push-pull rod 406. A sealing structure is arranged at the end of the push-pull rod 406 arranged inside the box body 402 to facilitate the pumping of the gas inside the piston box 2021. In order to better fix the connecting pipe 403 and the threaded rod 405, a fixed sleeve rod is sleeved on the connecting pipe 403 and the threaded rod 405. The threaded rod 405 is connected to the fixed rod sleeve through a bearing. Further, in order to control the moving direction of the threaded rod 405, a guide rod is added to the threaded rod 405. One end of the guide rod is fixedly connected to the fixed rod sleeve.

[0026] In order to adjust the heights of the cylinder 304 and the photographing device 302, the following technical solutions are adopted for this device: The support plate 301 passes through the top plate of the frame 1, and an auxiliary component II 5 is connected to its bottom. A groove is formed on the side of the support plate 301, and a slide bar 3011 is arranged in the groove. The slide bar 3011 is L-shaped. The cross bar of the slide bar 3011 is slidably embedded in the groove, and the bottom end of its vertical bar is fixedly connected to the top plate of the frame 1, enabling the support plate 301 to move up and down to ensure that the axis of the cylinder 304 is aligned with the axis of the steel. The auxiliary component II 5 includes a horizontal gear 501, a vertical gear 502, and a support rod 503. The top end of the support rod 503 is connected to the top plate of the frame 1 through a bearing, and its bottom end is connected to the bottom plate of the frame 1 through a bearing. The support rod 503 is slidably connected to the support plate 301 to provide support and guidance for the support plate 301. One way of the sliding connection is to sleeved a sliding block on the support rod 503, and the sliding block is fixedly connected to the support plate 301. The movement of the support plate 301 is driven by the sliding of the sliding block. The support rods 503 are arranged in pairs, and sprockets 7 are arranged on each of the paired support rods 503. A chain 6 is connected to the outside of the two sprockets 7, and the chain 6 drives the movement of the two support rods 503. A horizontal gear 501 is arranged at the bottom end of one of the support rods 503, and the horizontal gear 501 is sleeved on the bottom end of the support rod 503. A meshing vertical gear 502 is arranged on the side of the horizontal gear 501, and the vertical gear 502 is perpendicular to the horizontal gear 501. A connecting rod 504 is arranged on the side of the vertical gear 502, and the connecting rod 504 is connected to the auxiliary component I 4. In order to better support the connecting rod 504, a support block is sleeved on the connecting rod 504, and the support block is fixed to the bottom plate of the frame 1. In this way, the connecting rod 504 can be supported and guided.

[0027] In order to realize the coordinated action of the auxiliary component I 4 and the auxiliary component II 5, the following technical solution is adopted for this device: A sprocket 7 is arranged at the end of the threaded rod 405, and a sprocket 7 is arranged at the end of the connecting rod 504. The sprocket 7 at the end of the threaded rod 405 is connected to the sprocket 7 at the end of the connecting rod 504 through a chain 6, so that the auxiliary component II 5 is driven by the electric device 401 to move synchronously with the auxiliary device I.

[0028] The design of the first auxiliary component 4 can adjust the angle between the two conveyors 201, and the design of the second auxiliary component 5 can adjust the heights of the cylinder 304 and the photographing device 302. Through the combination of the sprocket 7 and the chain 6, the first auxiliary component 4 and the second auxiliary component 5 can cooperate with each other under the action of the same electric device 401 to ensure that the cylinder 304 and the steel are on the same axis. The electric device 401 uses a high-torque motor, which can provide sufficient power for the first auxiliary component 4 and the second auxiliary component 5. During adjustment, it is not necessary to be particularly precise about the rotation angle of the conveyor 201 and the rising height of the cylinder 304. As long as it is ensured that while the conveyor 201 is opening, the cylinder 304 is rising, so that the opening of the conveyor 201 causes the height of the steel to decrease, and it will always intersect with the rising cylinder 304 and there is an overlap of the central axis, the effect described in this solution can be achieved. Further, in order to better adapt the angle adjustment of the conveyor 201 to the height adjustment of the cylinder 304, the transmission mode of the chain 6 and the sprocket 7 connecting the first auxiliary component 4 and the second auxiliary component 5 can be replaced with a stepless speed reducer for driving. The speed reducer can make the first auxiliary component 4 and the second auxiliary component 5 act more precisely in coordination.

[0029] There are three ways to set the conveyor 201 for transporting steel and the photographing device 302. The first way is that the conveyor 201 transports the steel towards the cylinder 304, and multiple photographing devices 302 are arranged at fixed positions on the circumferential side of the cylinder 304. Through the coverage of the photographing ranges of the multiple photographing devices 302, the steel transported by the conveyor 201 is photographed without dead angles. The second way is that the conveyor 201 transports the steel towards the cylinder 304, and the photographing device 302 is set to be rotatable around the circumferential side of the cylinder 304. Through the rotation of the photographing device 302, the steel transported by the conveyor 201 is photographed without dead angles. The third way is that while the conveyor 201 transports the steel towards the cylinder 304, the steel is rotated. The rotation of the steel can be manual. The photographing device 302 is set to be rotatable around the circumferential side of the cylinder 304. Through the mutual rotation of the photographing device 302 and the steel, the steel transported by the conveyor 201 is photographed without dead angles.

[0030] The above setting the photographing device 302 to be rotatable around the circumferential side of the cylinder 304 and realizing the dead-angle-free photographing of the steel transported by the conveyor 201 through the rotation of the photographing device 302 is achieved by the following technical solution: The support plate 301 is provided with a cylinder 304 for the steel to pass through. A slip ring 3041 is sleeved on the outer peripheral side of the cylinder 304 close to the conveyor 201. A matching slider is arranged on the slip ring 3041, and the slider is fixedly connected with the photographing device 302. The photographing device 302 can adopt a CCD high-definition camera. The design of the slip ring 3041 and the slider can ensure that the electrical signal is normally transmitted when the photographing device 302 rotates. During use, one end of the wire harness can be connected to the slider and the other end to the slip ring 3041, so that the electrical signal can be normally transmitted during rotation. A gear ring 3042 is sleeved on the outer peripheral side of the cylinder 304 far from the conveyor 201. A braking gear 3043 is meshed above the gear ring 3042. The braking gear 3043 is connected to the power generation device 305 through a rotating shaft 3044. The power generation device 305 is fixed to the support plate 301 through an L-shaped plate 306. The horizontal plate of the L-shaped plate 306 is fixedly attached to the top of the support plate 301, and the power generation device 305 is fixed to the outside of its vertical plate. The horizontal plate of an L-shaped plate 307 is fixed to the side of the support plate 301. A through rod 308 passing through the support plate 301 is fixed to the vertical plate of the L-shaped plate 307. The through rod 308 and the rotating shaft 3044 are connected through a damping bearing. A display screen 303 is arranged on the side of the support plate 301. The display screen 303 is electrically connected to the photographing device 302, which is convenient for processing and analyzing the information collected by the photographing device 302.

[0031] Further, the problem that the lens of the photographing device 302 is contaminated will occur during operation. In order to clean the lens, the following technical solution is adopted: A moving block 309 is slidably connected below the horizontal plate of the L-shaped plate 307. The moving block 309 penetrates through the through rod 308. A U-shaped frame 310 is fixed to the bottom of the moving block 309. The opening of the U-shaped frame 310 faces the support plate 301, and a cleaning device 311 is fixed inside it. Two stoppers 312 are arranged on the bottom surface of the horizontal plate of the L-shaped plate 307. The two stoppers 312 are located at both ends of the moving track of the moving block 309. Further, in order to reduce the wear on the bottom surface of the horizontal plate of the L-shaped plate 307 and limit the direction of the moving block 309, a sliding groove is added to the bottom surface of the horizontal plate of the L-shaped plate 307. The two ends of the sliding groove are connected to the two stoppers 312, ensuring that the moving block 309 can move along a fixed direction and within a certain range under the action of the sliding groove and the stoppers 312.

[0032] The use process of the present invention is as follows: When detecting the rust of the steel, place the steel between the two conveyors 201, control the two conveyors 201 to work, convey the steel towards the cylinder 304, and the steel passes through the cylinder 304. As Figure 7As shown, while controlling the shooting device 302 to work and taking pictures of the outer surface of the steel, it is also necessary to control the power generation device 305 to rotate forward. The forward rotation of the power generation device 305 drives the rotation of the rotating shaft 3044. Since the through rod 308 is connected to the rotating shaft 3044 through a damping bearing, and the moving block 309 contacts the left stop block 312 and cannot move leftward continuously. At this time, the resistance of the left stop block 312 to the moving block 309 will be greater than the damping force of the damping bearing, making the rotation of the rotating shaft 3044 unable to drive the moving block 309 to rotate. However, the gear ring 3042 rotates normally, driving the braking gear 3043 to rotate. The rotation of the braking gear 3043 drives the rotation of the slider on the periphery of the cylinder 304, causing the shooting device 302 to rotate around the steel, so as to take pictures of the outer surface of the steel without dead angles. When there is rust on the steel, the shooting device 302 takes pictures and transmits them to the display screen 303. The staff can know whether there is a rust problem on the steel through the display screen 303, and then mark and process the steel that does not meet the quality requirements, finally completing the rust detection of the steel. During the detection process, the staff only needs to continuously place the steel on the conveyor 201; When the diameter of the steel increases, the angle between the two conveyors 201 is small and the steel cannot be placed stably. Therefore, control the electric device 401 to work to adjust the angle between the two conveyors 201. The work of the electric device 401 drives the rotation of the threaded rod 405. The rotation of the threaded rod 405 drives the push-pull rod 406 to move to the right, exhausting the gas in the box body 402. Then, under the action of the connecting pipe 403 and the hose 404, the air in the piston box 2021 is sucked into the box body 402. At this time, the piston rod 2022 in the piston box 2021 moves in the direction close to the hose 404. Since the piston rod 2022 is hinged to the conveyor 201 and the piston box 2021 is rotatably connected to the frame 1, when the piston rod 2022 moves, it pulls the back side of the conveyor 201, and then makes the two conveyors 201 rotate, realizing the adjustment of the angle between the two conveyors 201. In this way, when performing rust detection, the angle between the two conveyors 201 can be adjusted appropriately according to the diameter of the steel. This device can convey steel with different diameters, so as to perform rust detection work on steel with different diameters, and has a wide range of applications; Among them, the rotation of the threaded rod 405 causes the sprocket 7 to rotate. The rotation of the sprocket 7 drives the connecting rod 504 to rotate. The rotation of the connecting rod 504 drives the vertical gear 502 to rotate. The rotation of the vertical gear 502 drives the horizontal gear 501 to rotate. The rotation of the horizontal gear 501 drives the rear support rod 503 to rotate. The rotation of the support rod 503 drives the chain 6 to rotate. The rotation of the chain 6 drives the front support rod 503 to rotate, causing the two support rods 503 to rotate simultaneously. The rotation of the two support rods 503 drives the two threaded blocks to move upward, thereby causing the moving plate to move upward. The upward movement of the moving plate causes the cylinder 304 and the photographing device 302 to slowly move upward. When the angle between the two conveyors 201 is increased, the height of the cylinder 304 and the photographing device 302 can be adjusted synchronously. When the steel is placed on the two conveyors 201, it can be ensured that the axis of the steel is in the same position as the axis of the cylinder 304, so as to ensure that when the photographing device 302 rotates around the steel, there will be no phenomenon of hitting the steel; After the photographing device 302 has been used for a period of time, dust will adhere to the lens. At this time, control the power generation device 305 to reverse, driving the rotation of the rotating shaft 3044, causing the gear ring 3042, the braking gear 3043, the slider and the photographing device 302 to rotate in the opposite direction. The rotation of the rotating shaft 3044 can also cause the through rod 308 to rotate in the opposite direction, thereby causing the moving block 309 to move to the right, driving the U-shaped frame and the cleaning device 311 to move to the right. When the moving block 309 contacts the right stop block 312, the cleaning device 311 is located below the lens of the photographing device 302. The resistance of the right stop block 312 to the moving block 309 will be greater than the damping force of the damping bearing, and the rotation of the rotating shaft 3044 will not cause the through rod 308 to continue to rotate, causing the cleaning device 311 to stay at the position below the lens of the photographing device 302. Coupled with the rotation of the slider and the photographing device 302 in the opposite direction, the lens of the photographing device 302 will intermittently contact the cleaning device 311. When contacting, the cleaning device 311 can clean the lens of the photographing device 302, thereby realizing the cleaning of the lens dust; After the cleaning is completed, the rust detection work continues with the same principle.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
