[0002] With the development of the times and technology, the varieties and specifications of hot rolling are constantly expanding, and the precision requirements for products are getting higher and higher. Visual inspection of the lower surface of steel billets is an important part of the steel production process to identify whether the depth of the ignition groove of the slab is unqualified and whether there is any abnormal leakage on the surface of the slab to ensure the quality of the product.

[0003] The existing lower surface inspection uses visual inspection instead of human eyes to collect data on specific targets. However, the lower surface inspection system is usually installed directly below the production roller. The ambient temperature under the production track is high and there is a certain amount of dust and oil. The iron slag on the surface of the steel billet is easy to fall onto the inspection device window and block the window, resulting in the visual acquisition device being unable to obtain image information. In addition, large pieces of iron slag may even damage the window and equipment, which need to be cleaned regularly. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The present invention discloses a protective device for a lower surface detector, please refer to Figures 1 to 4The lower surface detector protection device includes a protection shell 1 and a fixing seat 2. The protection shell 1 includes a cover plate 11 and a receiving plate 12. A window 13 is vertically arranged on the receiving plate 12. That is to say, the window 13 is also perpendicular to the bottom plate of the protection shell 1. On the one hand, when the hot rolling production line is working normally, iron filings and dust will not fall directly on the window 13, avoiding oil or water vapor from being directly adsorbed on the window 13; on the other hand, when a large iron block accidentally falls on the protection shell 1, the iron block will not fall directly on the window 13, avoiding the situation where the high-temperature iron block damages the window 13, enhancing the service life of the entire lower surface detector protection device, and at the same time ensuring the installation of the lower surface detector 10 inside the protection shell 1, avoiding unnecessary financial losses. The lower surface detector detects the lower surface of the billet from the lower surface detector protection device through the window 13. The fixing seat 2 is accommodated in the protection shell 1, and is used to connect the lower surface detector to ensure that the lower surface detector is stably fixed in the lower surface detector protection device. The fixing seat 2 includes a slide groove 22, and the lower surface detector 10 is slidably connected to the slide groove 22, which ensures that the lower surface detector 10 can move relatively freely in the protective shell 1, so that the position of the lower surface detector 10 can be adjusted relatively easily according to actual needs. The accommodating plate 12 includes a first wall body 14 and a second wall body 15, and the window 13 is arranged on the first wall body 14, that is, at this time, the window 13 is arranged on the side wall of the entire lower surface detector protection device, which effectively avoids the viewing angle of the lower surface detector when detecting the steel billet being processed from being covered by oil in the working area or iron filings dropped from the steel billet or dust during processing, thereby ensuring the detection efficiency of the lower surface detector and the processing effect of the steel billet, and the air supply device 3 is arranged on the second wall body 15. The cover plate 11 covers the first wall 14 and the second wall 15, and the angle between the extension line of the cover plate 11 and the extension line of the first wall 14 is an acute angle. On the one hand, it ensures that the first wall 14 has a certain angle with the horizontal plane to prevent iron filings, oil stains, etc. from covering the window 13 and affecting the detection effect of the lower surface detector; on the other hand, the opening angle of the cover plate 11 can be expanded, making it easier to adjust and operate the interior of the lower surface detector protection device according to actual needs.

[0024] The lower surface detector 10 can be an industrial camera, which can realize high-speed shooting of the lower surface of the billet, and compare the acquired clear image with the preset image, and adjust the corresponding area of ​​the hot rolling production line in real time according to the comparison result to ensure the accuracy of the billet. The window 13 is made of sapphire glass, which has high hardness, wear resistance, scratch resistance, excellent thermal properties and good light transmittance, and is more suitable for ensuring that the lower surface detector can capture clear images in the hot rolling production line while protecting the safety effect of the lower surface detector.

[0025] In actual use, due to the different sizes of processed steel billets, the position of the lower surface detector 10 in the protective shell 1 also needs to be adjusted. In some embodiments, the fixed seat 2 includes a mounting bracket 21, and the mounting bracket 21 is slidably connected to the slide groove 22. The lower surface detector 10 is installed on the mounting bracket 21. The position of the lower surface detector 10 in the protective shell 1 is adjusted according to different needs or sizes. Since the slide groove 22 is set on the fixed seat 2, when the position of the lower surface detector 10 is adjusted by the slide groove 22, there is no need to re-find a suitable position and adjust the parameters of the lower surface detector, which simplifies the adjustment steps of the lower surface detector 10, ensuring that the required detection image can be accurately obtained during the detection process, and the hot rolling production line can be adjusted in time according to the image to ensure the accuracy requirements of the production of steel billets.

[0026] Furthermore, in order to ensure that the lower surface detector 10 can detect the lower surface of the steel billet more comprehensively, in some embodiments, the mounting bracket 21 includes a fixed plate 23 and an adjustment plate 24, and the adjustment plate 24 can rotate around the fixed plate 23 to adjust the orientation angle of the lower surface detector 10, so that it can detect the lower surface of the steel billet at different angles according to actual needs. Among them, a slider 25 is provided on the fixed plate 23, and a sliding groove 26 is provided on the adjustment plate 24. The sliding groove 26 is an arc groove, and the slider 25 is slidably connected in the sliding groove 26. According to actual needs, without changing the position of the lower surface detector 10, the position of the slider 25 in the sliding groove 26 is adjusted to change the angle of the lower surface detector 10, thereby reducing the possibility of errors caused by the adjustment of the position of the lower surface detector 10, and ensuring the accuracy of the lower surface detector 10 when detecting the steel billet.

[0027] Similarly, in order to further ensure the flexibility of the lower surface detector 10 in the protective shell 1, in some embodiments, the fixed plate 23 also includes an adjustment slot 27 arranged along the direction of gravity, and the adjustment plate 24 can move up and down along the adjustment slot 27, thereby realizing the adjustable height of the lower surface detector 10. The adjustment plate 24 includes a locking piece 28, and the locking piece 28 is slidably connected in the adjustment slot 27. When the lower surface detector 10 and the adjustment plate 24 are adjusted to a suitable position together, the locking piece 28 is used to fix the two at corresponding positions in the adjustment slot 27 to maintain the lower surface detector 10 Stably fixed on the fixed base 2, to avoid the lower surface detector 10 falling off the fixed plate 23 due to vibration when the protective shell 1 is hit by iron filings or other debris, thereby affecting the subsequent detection of the lower surface detector 10.

[0028] When the size of the steel billet to be inspected is large, it takes a long time to inspect the steel billet. In some embodiments, a plurality of lower surface detectors 10 may be provided, and a plurality of slide grooves 22 are correspondingly provided at the fixed seat 2. By providing a plurality of lower surface detectors 10, it is possible to inspect multiple locations of a larger steel billet at the same time, thereby avoiding the need to move the lower surface detector 10 multiple times during inspection, which affects the inspection efficiency.

[0029] In some embodiments, the lower surface detector protection device also includes an air supply device 3, which is arranged on the outside of the protective shell 1, and the fixed seat 2 includes a cooling pipe 5, the outlet 51 of the cooling pipe 5 is arranged toward the lower surface detector 10, and the air supply device 3 is connected to the cooling pipe 5, which is used to cool the lower surface detector 10 to prevent the lower surface detector 10 from being affected by the high temperature of the working environment or heating up when working for a long time to affect its shooting speed, thereby affecting the subsequent processing accuracy of the steel billet.

[0030] Furthermore, the lower surface detector protection device also includes a dust removal device 4, which is arranged on the first wall 14 and located above the window 13, wherein the dust removal device 4 can be a stainless steel air knife, which is used to blow away impurities such as floating dust on the window 13, maintain the overall cleanliness of the window 13, and enable the lower surface detector 10 to capture high-definition images. The air supply device 3 is connected to the dust removal device 4, and is used to provide power for the dust removal device 4.

[0031] It is understandable that the air supply device 3 can provide compressed air, nitrogen and other media to achieve the functions of blowing the window and cooling the lower surface detector. Two or more air supply devices 3 can be provided, corresponding to the dust removal device 4 and the cooling pipeline 5 one by one, so that the dust removal device 4 or the cooling pipeline 5 can be opened separately according to actual needs.

[0032] Furthermore, when there are multiple lower surface detectors 10, there are also multiple dust removal devices 4 and outlets 51 of the cooling duct 5, which correspond one-to-one to the lower surface detectors 10, to always ensure that the working temperature of the lower surface detector 10 and the shooting angle are free of debris that may affect the shooting and detection, thereby ensuring the processing accuracy of the steel billet.

[0033] In some embodiments, the lower surface detector protection device also includes a cover plate 11, which is arranged at the junction of the cover plate 11 and the first wall 14. The dust removal device 4 is arranged below the cover plate 11 to prevent iron filings and other debris from falling during steel processing and damaging the dust removal device 4, thereby affecting the cleaning of dust and oil on the surface of the window 13.

[0034] In some embodiments, the lower surface detector protection device further includes a hinge structure 6, which is disposed between the cover plate 11 and the receiving plate 12, and the cover plate 11 is rotatably connected to the receiving plate 12. The cover plate 11 and the protective housing 1 are hingedly opened and closed, which can achieve a large opening and closing angle, facilitate the installation and maintenance of the structure in the protective housing 1, and also facilitate the adjustment of the lower surface detector 10.

[0035] In some embodiments, the lower surface detector protection device also includes a sealing strip 7, which is installed at the connection between the cover plate 11 and the receiving plate 12, wherein the edges of the cover plate 11 are all provided with sealing strips 7, thereby ensuring that the upper part of the lower surface detector protection device can have a certain degree of heat insulation and the sealing of the protective shell 1, thereby preventing steel slag, dust, etc. from entering the interior of the box and causing damage to the internal lower surface detector and fixed seat 2 and other structures.

[0036] It is understandable that due to the presence of the sealing strip 7 in the lower surface detector protection device, the external high temperature and humid air is isolated from the interior, but due to the influence of high temperature, the pressure in the protection shell 1 will become larger and larger. In some embodiments, a pressure relief valve 8 is also provided on the receiving plate 12. When the pressure in the protection shell 1 is greater than a preset value, the pressure relief valve 8 opens to release the gas in the protection shell 1 to maintain the air pressure in the protection shell 1 stable. The pressure relief valve 8 also includes a noise reduction component (not shown) to reduce the noise during decompression and improve the performance.

[0037] Furthermore, in order to ensure that the pressure relief valve 8 does not affect the gas supply device 3 when it is opened, in some embodiments, the pressure relief valve 8 is arranged on a second wall 15 away from the gas supply device 3 to prevent high-temperature gas from rushing towards the gas supply device 3 and causing damage to the gas supply device 3 when the pressure relief valve 8 is opened.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
