[0010] In some embodiments, the steel inspection device further includes a conveying assembly comprising a plurality of conveying rollers spaced apart in a first direction, all of which are rotatably connected to a base and partially located within a conveying channel. The projection of the inspection assembly in a second direction lies between partially adjacent conveying rollers.

[0011] In some embodiments, the first wall and the conveying roller are spaced apart in a second direction to form a partial conveying channel. The first wall is recessed inward to form a receiving space, and the detection component is located inside the receiving space, with the side of the detection component facing the conveying roller located on the side of the first wall opposite to the conveying roller.

[0020] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended only to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] With societal development, steel is widely used in various fields such as construction, machinery manufacturing, automobiles, shipbuilding, and bridges. Different fields have different performance requirements for steel. To ensure steel quality, it needs to undergo certain tests after production and forming.

[0023] Thickness uniformity is an important indicator in steel testing. In practice, it is often represented by the maximum thickness difference between any two points on the steel. Therefore, thickness testing is required for steel after it has been manufactured.

[0024] In related technologies, the thickness detection of steel only involves detecting the sampling location, which makes it difficult to form a comprehensive test of the steel, and the resulting test results are not accurate.

[0025] In view of this, please refer to Figure 1 , Figure 2 and Figure 3 This application provides a steel testing device, including a base 10 and a testing component 20. The base 10 has a conveying channel T extending along a first direction X, used for conveying and transferring steel. The base 10 includes a first wall 11 located on the side of the conveying channel T along a second direction Y. The testing component 20 is connected to the base 10 and includes a plurality of testing elements 21 spaced apart along a third direction Z. At least some of the testing elements 21 have their projections in the second direction Y located on the first wall 11. The first direction X, the second direction Y, and the third direction Z intersect each other. The testing component 20 is slidably disposed relative to the base 10, and the projection size of the sliding distance of a single testing element 21 in the third direction Z is not less than the projection size of the distance between adjacent testing elements 21 in the third direction Z.

[0026] The steel testing device provided in this application embodiment is used to test steel after it has been produced and formed, in order to determine whether certain parameters of the steel are qualified, thereby judging the quality of the steel. For example, the steel testing device provided in this application embodiment can be used to test the thickness of the steel to obtain the same-plate difference data; or, the steel testing device provided in this application embodiment can also be used to test the surface roughness of the steel.

[0027] Specifically, the steel inspection device provided in this application includes a base 10 and an inspection component 20 connected to the base 10. A conveying channel T for conveying and transferring steel is provided through the base plate along a first direction X. When the steel passes through the conveying channel T, the inspection component 20 can detect specific data of the steel. Taking the inspection component 20 detecting the thickness of the steel as an example, during the process of the steel passing through the conveying channel T, it simultaneously passes through the inspection component 20. The inspection component 20 can detect multiple positions of the steel it passes through to obtain the thickness of the steel at different positions. When the inspection component 20 is used to detect the thickness of the steel, the detection element 21 in the inspection component 20 can be set as a X-ray thickness gauge.

[0028] To improve the accuracy of steel detection by the detection component 20, the base 10 includes a first wall 11 located on one side of the conveying channel T along the second direction Y. The detection component 20 includes multiple detection elements 21 spaced apart along the third direction Z. At least some of the detection elements 21 are projected onto the first wall 11 in the second direction Y. The first direction X, the second direction Y, and the third direction Z intersect each other. Considering that steel is often a cuboid plate structure, its dimensions in the length, width, and thickness directions are different. The first direction X can be parallel to the length direction of the steel, the second direction Y can be parallel to the thickness direction of the steel, and the third direction Z can be parallel to the width direction of the steel. The first direction X and the third direction Z intersect to form a horizontal plane, and the second direction Y can correspond to the vertical direction. Multiple detection elements 21 are provided and spaced apart along the width direction of the steel. The coverage area of ​​the multiple detection elements 21 is greater than the extension dimension of the steel in the width direction. The multiple detection elements 21 can form a large detection range in the width direction of the steel, thereby obtaining more comprehensive detection data to ensure the accuracy of the relevant detection data.

[0029] To further improve the detection accuracy of the detection component 20, the detection component 20 is slidably positioned relative to the base 10 to expand its detection range and obtain more comprehensive detection data. During the steel conveying process, the steel can sequentially enter and exit the conveying channel T at various positions along its length. Simultaneously, the steel passes through the detection component 20 at various positions along its length, allowing the detection component 20 to detect the steel at each position along its length.

[0030] To ensure comprehensive coverage of the steel's width direction by the detection assembly 20, the projected dimension of the sliding distance of a single detection element 21 in the third direction Z is not less than the projected dimension of the interval between adjacent detection elements 21 in the third direction Z. Multiple detection elements 21 are spaced apart in the third direction Z to correspond to multiple positions of the steel in the width direction. Simultaneously, the detection elements 21 are slidably positioned relative to the base 10, meaning that as the steel passes through, the detection elements 21 can change their position relative to the steel, thereby detecting data at different positions of the steel. During the sliding process of the detection elements 21, their sliding distance can cover the spacing between adjacent detection elements 21, thus detecting data at different positions of the steel in the width direction. Through the above arrangement, the detection ranges of adjacent detection elements 21 overlap in the width direction of the steel, ensuring detection at all positions in the width direction of the steel. Combined with the transmission of the steel in the conveying channel T, it is possible to detect all positions on the steel surface, obtaining comprehensive detection data to ensure the accuracy of the relevant detection data.

[0031] In summary, in this embodiment, the steel inspection device is used to inspect steel after production and forming to determine whether certain parameters of the steel are qualified, thereby judging the quality of the steel. The steel inspection device includes a base 10 and an inspection component 20 connected to the base 10. A conveying channel T for transporting and transferring steel is provided through the base along a first direction X. When the steel passes through the conveying channel T, the inspection component 20 can detect specific data of the steel. To improve the accuracy of the inspection of the steel by the inspection component 20, the base 10 includes a first wall 11 located on the side of the conveying channel T along a second direction Y. The inspection component 20 includes multiple inspection elements 21 spaced apart along a third direction Z. At least some of the inspection elements 21 have their projections in the second direction Y located on the first wall 11. The first direction X, the second direction Y, and the third direction Z intersect each other. Multiple inspection elements 21 are provided and spaced apart along the width direction of the steel. The coverage area of ​​the multiple inspection elements 21 is greater than the extension dimension of the steel in the width direction, and the multiple inspection elements 21 can form a large inspection range in the width direction of the steel. Furthermore, the detection assembly 20 is slidably disposed relative to the base 10. The projection dimension of the sliding distance of a single detection element 21 in the detection assembly 20 in the third direction Z is not less than the projection dimension of the interval between adjacent detection elements 21 in the third direction Z. During the sliding process of the detection element 21, its sliding distance can cover the spacing between adjacent detection elements 21, thereby detecting data at different positions of the steel in the width direction. The detection ranges of adjacent detection elements 21 have overlapping portions in the width direction of the steel to ensure that each position in the width direction of the steel is detected. Combined with the transmission of the steel in the conveying channel T, it is possible to detect each position on the surface of the steel, obtain comprehensive detection data, and ensure the accuracy of the relevant detection data.

[0032] In some embodiments, the sliding direction of the detection element 21 intersects both the first direction X and the third direction Z. In the first direction X, the advancing direction of the detection element 21 relative to the base 10 is consistent with the advancing direction of the steel relative to the base 10.

[0033] Considering that the steel is constantly moving forward in the conveying channel T, the detection element 21 can be configured as an inclined sliding element to adapt to the forward movement of the steel. Specifically, the sliding direction of the detection element 21 intersects both the first direction X and the third direction Z. That is, the sliding direction of the detection element 21 includes a component in the first direction X and a component in the third direction Z. In the first direction X, the forward movement of the detection element 21 relative to the base 10 is consistent with the forward movement of the steel relative to the base 10. Based on the component of the sliding direction of the detection element 21 in the first direction X, the detection element 21 can move forward with the steel in the first direction X. Based on the component of the sliding direction of the detection element 21 in the third direction Z, the detection element 21 can move along the third direction Z, which is the width direction of the steel, to detect data at different positions of the steel in the width direction.

[0034] In the first direction X, both the detection element 21 and the steel have a certain sliding speed. When the sliding speeds of the detection element 21 and the steel are equal, the detection element 21 is in a relatively stationary state relative to the steel in the first direction X, and the data detected by the detection element 21 is linear data in the width direction of the steel. When the sliding speed of the detection element 21 is greater than the sliding speed of the steel, the detection element 21 can complete the detection of the steel before the steel slides out of the conveying channel T, thereby improving the detection efficiency.

[0035] In some embodiments, the steel testing device includes a connecting assembly 30, which is connected between the testing assembly 20 and the base 10. The connecting assembly 30 includes a first connecting member 31, a second connecting member 32, and a third connecting member 33 connected end to end in sequence. The first connecting member 31 extends along a first direction X, the second connecting member 32 extends along a third direction Z, and the extension direction of the third connecting member 33 intersects both the first direction X and the third direction Z. A plurality of testing members 21 are slidably connected to the third connecting member 33.

[0036] To facilitate the connection between the detection component 20 and the base 10, the steel detection device also includes a connecting component 30, which connects the detection component 20 and the base 10. In this embodiment, considering that the detection component 21 is usually small in size, the connecting component 30 is provided with a frame structure to facilitate the connection of the detection component 21.

[0037] Specifically, the connecting component 30 includes a first connector 31, a second connector 32, and a third connector 33 connected end-to-end. These three connectors form a triangular frame structure to improve the connection stability of the connecting component 30 itself, and indirectly improve the connection stability between the detection component 20 and the base 10. The first connector 31 extends along a first direction X, the second connector 32 extends along a third direction Z, and the extension direction of the third connector 33 intersects both the first direction X and the third direction Z. The first connector 31, the second connector 32, and the third connector 33 form a right-angled triangular frame structure. The third connector 33 is located at the hypotenuse of the right-angled triangle and has the longest length, facilitating the placement of the detection components 21 and allowing for the placement of a larger number of detection components 21. Therefore, multiple detection components 21 are slidably connected to the third connector 33.

[0038] In some embodiments, the first connector 31, the second connector 32, and the third connector 33 are all hingedly connected. The first connector 31 includes a first portion 311 and a second portion 312 that are slidably connected in its extending direction. The third connector 33 includes a third portion 331 and a fourth portion 332 that are slidably connected in its extending direction. A partial detection element 21 is disposed in the third portion 331 and the fourth portion 332. The first portion 311 and the second portion 312 are telescopically slidable to adjust the extending direction of the third connector 33.

[0039] In actual testing, the tilt angle of the extension direction of the third connector 33 can affect the component of the sliding speed of the detection piece 21 in the first direction X. In order to adjust the tilt angle of the extension direction of the third connector 33 so that the sliding speed of the detection piece 21 can be flexibly adapted to the transmission speed of the steel, in this embodiment, the first connector 31 and the third connector 33 are configured to be length-adjustable. By adjusting the length of the first connector 31, the length and extension direction of the third connector 33 can be changed.

[0040] Specifically, the first connecting member 31, the second connecting member 32, and the third connecting member 33 are all hinged together. At the connection position between the first connecting member 31 and the second connecting member 32, the first connecting member 31 and the second connecting member 32 can rotate relative to each other around the second direction Y; at the connection position between the first connecting member 31 and the third connecting member 33, the first connecting member 31 and the third connecting member 33 can rotate relative to each other around the second direction Y; based on the connection position between the second connecting member 32 and the third connecting member 33, the second connecting member 32 can rotate relative to each other around the second direction Y. When the extension direction of the third connecting member 33 changes, the included angle between the third connecting member 33 and the first connecting member 31 and the second connecting member 32 will also change. The hinged connection ensures the flexible adjustment of the third connecting member 33.

[0041] The first connector 31 includes a first portion 311 and a second portion 312 slidably connected in its extending direction, and the third connector 33 includes a third portion 331 and a fourth portion 332 slidably connected in its extending direction. For the first connector 31, the overall length of the first connector 31 can be changed by adjusting the overlap length between the first portion 311 and the second portion 312. Similarly, for the third connector 33, the overall length of the third connector 33 can be changed by adjusting the overlap length between the third portion 331 and the fourth portion 332. When the length of the first connector 31 increases, the length of the third connector 33 correspondingly increases, the extending direction of the third connector 33 changes accordingly, and the angle between the first connector 31 and the third connector 33 decreases. When the length of the first connector 31 decreases, the length of the third connector 33 correspondingly decreases, the extending direction of the third connector 33 changes accordingly, and the angle between the first connector 31 and the third connector 33 increases.

[0042] In some embodiments, the third connector 33 includes a first connector 333 and a second connector 334 that are offset from each other. The projection of the first connector 333 in the first direction X and the projection of the second connector 334 in the first direction X overlap. A portion of the detection element 21 is slidably connected to the first connector 333, and a portion of the detection element 21 is slidably connected to the second connector 334. The sliding range of the slider connected to the first connector 333 and the sliding range of the slider connected to the second connector 334 partially overlap.

[0043] To facilitate the installation of the detection element 21 on the third connector 33, the third connector 33 further includes a first connecting part 333 and a second connecting part 334. The first connecting part 333 can be connected to the third part 331, and the second connecting part 334 can be connected to the fourth part 332. Some of the detection elements 21 are disposed in the first connecting part 333, and some of the detection elements 21 are disposed in the second connecting part 334.

[0044] To ensure that the testing component 21 can detect all positions of the steel in the width direction, the first connecting part 333 and the second connecting part 334 are partially overlapped in the third direction Z. The sliding range of the sliding member provided in the first connecting part 333 and the sliding range of the sliding member provided in the second connecting part 334 are also partially overlapped, so as to ensure that the testing component 21 can perform comprehensive detection in the width direction of the steel.

[0045] In some embodiments, the steel inspection device further includes a conveying assembly 40, which includes a plurality of conveying rollers 41 spaced apart in a first direction X. Each of the conveying rollers 41 is rotatably connected to the base 10 and is partially located inside the conveying channel T. The projection of the inspection assembly 20 in the second direction Y lies between some adjacent conveying rollers 41.

[0046] The conveying assembly 40 is connected to the base 10 and is used to transport steel within the conveying channel T. The conveying assembly 40 includes a plurality of conveying rollers 41, which are spaced apart in the first direction X and are rotatably connected to the base 10. It should be noted that the distance between two adjacent conveying rollers 41 in the first direction X is less than the length of the steel to ensure smooth transport of the steel by the conveying rollers 41.

[0047] Multiple conveying rollers 41 are partially located inside the conveying channel T. That is, when the steel is on the conveying rollers 41, there is a gap between the steel and the side wall of the conveying channel T. This is to avoid contact friction between the steel and the base 10, which would affect the conveying of the steel by the conveying rollers 41. For example, when the conveying rollers 41 convey the steel horizontally, the top of the conveying rollers 41 is above the bottom wall of the conveying channel T in the vertical direction. When the steel is supported and transported by the conveying rollers 41, there is a gap between the steel and the bottom wall of the conveying channel T in the vertical direction. This is to avoid contact between the steel and the bottom wall of the conveying channel T and ensure the smooth transport of the steel by the conveying rollers 41.

[0048] The projection of the detection component 20 in the second direction Y is located between some adjacent conveying rollers 41. The detection component 20 is set inside the conveying channel T. After the steel forms a stable conveying state in the conveying channel T, it gradually passes through the detection component 20. The detection component 20 detects the steel in the stable conveying state to improve the accuracy of the detection data.

[0049] In some embodiments, the first wall 11 and the conveying roller 41 are spaced apart in the second direction Y to form a partial conveying channel T. The first wall 11 is recessed inward to form a receiving space K, and the detection component 20 is located inside the receiving space K. The side of the detection component 20 facing the conveying roller 41 is located on the side of the first wall 11 opposite to the conveying roller 41.

[0050] The first wall 11 is the top wall of the conveying channel T in the second direction Y. When the steel is in the conveying channel T, it is located between the first wall 11 and the conveying roller 41. To reduce the impact of the steel on the detection component 20, a receiving space K is provided on the first wall 11. The detection component 20 is located inside the receiving space K, with the side of the detection component 20 facing the conveying roller 41 located on the side of the first wall 11 away from the conveying roller 41. The receiving space K provides a certain degree of protection around the detection component 20. When the steel passes through the detection component 20, due to the restriction of the first wall 11 at the non-recessed position, and the fact that the steel has a certain length, placing the detection component 20 inside the receiving space K can provide a certain degree of protection for the detection component 20.

[0051] In some embodiments, the accommodating space K is disposed through the base 10 along at least one side of the third direction Z, and a guide rail 12 extending along the third direction Z is provided on the side wall of the accommodating space K. The steel detection device includes a connecting assembly 30, which is connected between the detection assembly 20 and the base 10. The connecting assembly 30 includes a connecting seat 34, which is slidable along the third direction Z and detachably connected to the guide rail 12.

[0052] During actual testing, the testing component 21 may malfunction, requiring repair or replacement. Therefore, the accommodating space K is provided to penetrate the base 10 along at least one side of the third direction Z, allowing the testing component 20 to be moved out from the side of the accommodating space K penetrating the base 10, facilitating repair or replacement by technicians.

[0053] Specifically, a guide rail 12 extending in the third direction Z is provided on the side wall of the accommodating space K. The connecting assembly 30 includes a connecting seat 34, which slides along the third direction Z and is detachably connected to the guide rail 12. When the detection component 21 malfunctions, the connecting seat 34 can drive the detection component 21 to slide into the accommodating space K and separate it from the base 10, allowing technicians to repair or replace the detection component 21. After repair, the connecting component is reconnected to the guide rail 12 and slid to the required position to continue testing the steel.

[0054] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The steel testing device also includes a guide assembly 50 connected to the base 10. The guide assembly 50 includes a first guide member 51 and a second guide member 52 disposed on both sides of the conveying roller 41 along the third direction Z. The projection of the testing assembly 20 in the third direction Z is located inside the projections of the first guide member 51 and the second guide member 52 in the third direction Z.

[0055] When steel enters the conveying channel T in a skewed posture, it will affect the conveying effect of the conveying roller 41 on the steel, and thus affect the detection effect of the detection component 20 on the steel. In order to ensure the detection effect on the steel, a first guide 51 and a second guide 52 are provided on both sides of the conveying roller 41 along the third direction Z. The first guide 51 and the second guide 52 are located inside the conveying channel T and are used to contact the steel to adjust the spatial posture of the steel.

[0056] When the steel enters the conveying channel T in an oblique posture, the front part of the steel along the first direction X will first contact the first guide member 51 or the second guide member 52. Under the action of the conveying roller 41 and the first guide member 51 or the second guide member 52, the steel will rotate to a certain extent, so that the spatial orientation of the steel can be adjusted, so that the conveying roller 41 can stably convey the steel, thereby ensuring the detection effect of the detection component 20 on the steel.

[0057] In some embodiments, the first guide member 51 includes a first guide segment 511 and a second guide segment 512 connected to each other in the first direction X, and the second guide member 52 includes a third guide segment 521 and a fourth guide segment 522 connected to each other in the first direction X. The first guide segment 511 and the third guide segment 521 are disposed opposite to each other in the third direction Z, and the second guide segment 512 and the fourth guide segment 522 are disposed opposite to each other in the fourth direction. The distance between the first guide segment 511 and the third guide segment 521 gradually decreases along the direction closer to the second guide segment 512, and the distance between the second guide segment 512 and the fourth guide segment 522 is equal everywhere. The projection of the detection component 20 in the third direction Z is located inside the projections of the second guide segment 512 and the fourth guide segment 522 in the third direction Z.

[0058] When the first guide member 51 guides the steel, the steel first passes through the first guide section 511 and then through the second guide section 512; when the second guide member 52 guides the steel, the steel first passes through the third guide section 521 and then through the fourth guide section 522. The extension dimension of the first guide section 511 can be equal to the extension dimension of the third guide section 521, and the extension dimension of the second guide section 512 can be equal to the extension dimension of the fourth guide section 522.

[0059] To ensure efficient steel adjustment and reduce the probability of steel jamming, the distance between the first guide section 511 and the third guide section 521 is set to gradually decrease, which expands the adjustment range of the steel and improves the adjustment efficiency. When the steel passes through the second guide section 512 and the fourth guide section 522, it has already been adjusted by the first guide section 511 and the third guide section 521, and the steel is in a relatively stable conveying state. By positioning the detection component 20 relative to the extension range of the second guide section 512 and the fourth guide section 522, the impact of the steel conveying state on the detection effect can be reduced, ensuring the detection effect of the detection component 20.

[0060] In some embodiments, the steel detection device can be communicatively connected to a terminal controller. Exemplarily, the terminal controller can be a computer with control software installed on it, used to control the operation of the steel detection device. Further, the steel detection device can also be connected to a display, which displays the detection status of the detection element 21. Taking the detection of steel thickness as an example, the control software records the detection values ​​of the detection element 21 and automatically analyzes the maximum and minimum values, etc., of the detection values. Further, the control software can also control the sliding of the detection element 21.

[0061] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
