[0023] The utility model discloses a kind of lower surface detector protection devices, please refer to Figures 1 to 3The 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 containing plate 12. A window 13 is arranged on the containing plate 12. The lower surface detector 10 detects the lower surface of the billet from inside the lower surface detector protection device through the window 13. The fixing seat 2 is contained in the protection shell 1 and is used for connecting the lower surface detector 10 and ensuring that the lower surface detector 10 is stably fixed in the lower surface detector protection device. The containing plate 12 includes a first wall body 14 and a second wall body 15. The window 13 is arranged on the first wall body 14, that is, the window 13 is arranged on the side wall of the entire lower surface detector protection device, effectively avoiding the visual angle range of the lower surface detector 10 from being covered by oil stains in the working area or iron filings or dust falling from the billet during detection of the billet in the process, ensuring the detection efficiency of the lower surface detector 10 and ensuring the processing effect of the billet. The cover plate 11 is covered on the first wall body 14 and the second wall body 15. The included angle between the extension line of the cover plate 11 and the extension line of the first wall body 14 is an acute angle. On the one hand, the first wall body 14 has a certain angle with the horizontal plane, avoiding that iron filings and oil stains cover the window 13 and affect the detection effect of the lower surface detector 10. On the other hand, the opening angle of the cover plate 11 can be expanded, and it is easier to adjust and operate the inside 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 obtained clear image with a 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 transmission, and is more suitable for ensuring that the lower surface detector can shoot clear images while protecting the safety of the lower surface detector in the hot rolling production line.

[0025] In some embodiments, the included angle between the first wall body 14 and the bottom plate of the protection shell 1 is not greater than 90 degrees, that is, the first wall body 14 has a certain angle with the horizontal direction of the billet production line when arranged, so that the iron filings and dust falling from the hot rolling production line or the steel material on the first wall body 14 move downward under the action of gravity to avoid the dust from adhering to the window 13 and blocking the visual angle of the lower surface detector.

[0026] Further, the first wall body 14 is arranged perpendicularly to the bottom plate of the protective shell 1, that is, the window 13 is also arranged perpendicularly to the bottom plate of the protective shell 1. On the one hand, when the hot rolling production line is normally working, iron filings and dust cannot directly fall on the window 13, avoiding that oil stains or water vapor are directly adsorbed on the window 13. On the other hand, when a larger iron block accidentally falls on the protective shell 1, the iron block cannot directly fall on the window 13, avoiding that the high-temperature iron block damages the window 13, thereby prolonging the service life of the entire lower surface detector protection device and ensuring the installation of the lower surface detector 10 in the protective shell 1, avoiding unnecessary financial losses.

[0027] In actual use, the position of the lower surface detector 10 in the protective shell 1 needs to be adjusted due to different sizes of the processed billets. In some embodiments, the fixed seat 2 includes a mounting bracket 21 and a sliding groove 22. The lower surface detector 10 is mounted on the mounting bracket 21, and the mounting bracket 21 is movable in the sliding groove 22. The position of the lower surface detector 10 in the protective shell 1 can be adjusted according to different requirements or sizes. Since the sliding groove 22 is arranged on the fixed seat 2, when the position of the lower surface detector 10 is adjusted through the sliding groove 22, it is no longer necessary to find a suitable position and adjust the parameters of the lower surface detector, thereby simplifying the steps of adjusting the lower surface detector 10, ensuring that the required detection image can be accurately obtained during detection, and the hot rolling production line can be adjusted in a timely manner according to the image, thereby ensuring the precision requirements of the produced billets.

[0028] Further, in order to ensure that the lower surface detector 10 can more comprehensively detect the lower surface of the billet, in some embodiments, the mounting bracket 21 includes a fixed plate 23 and an adjusting plate 24. The adjusting plate 24 is rotatable about the fixed plate 23 to adjust the orientation angle of the lower surface detector 10, so that the lower surface detector 10 can detect the lower surface of the billet at different angles according to actual needs. The fixed plate 23 is provided with a sliding block 25, and the adjusting plate 24 is provided with a sliding groove 26. The sliding groove 26 is an arc-shaped groove, and the sliding block 25 is slidingly connected in the sliding groove 26. According to actual requirements, the position of the sliding block 25 in the sliding groove 26 is adjusted to change the angle of the lower surface detector 10 without changing the position of the lower surface detector 10, thereby reducing the possibility of errors of the lower surface detector 10 due to position adjustment and ensuring the accuracy of the lower surface detector 10 when detecting the billet.

[0029] Similarly, in order to further ensure the flexibility of the undersurface detector 10 in the protective shell 1, in some embodiments, the fixing plate 23 further comprises an adjusting groove 27 arranged along the direction of gravity, and the adjusting plate 24 is movable up and down along the adjusting groove 27, thereby realizing the adjustable height of the undersurface detector 10. The adjusting plate 24 comprises a locking member 28 which is slidingly connected in the adjusting groove 27. When the undersurface detector 10 and the adjusting plate 24 are jointly adjusted to the appropriate position, the locking member 28 is used to fix them at the corresponding position in the adjusting groove 27, thereby maintaining the stable fixation of the undersurface detector 10 on the fixing seat 2, avoiding the undersurface detector 10 from falling off the fixing 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 undersurface detector 10.

[0030] When the detected billet size is large, the detection time of the billet is long, and in some embodiments, the undersurface detector 10 can be provided with multiple undersurface detectors 10, and the fixing seat 2 is correspondingly provided with multiple sliding grooves 22. By providing multiple undersurface detectors 10, multiple places of a large-sized billet can be detected at the same time, thereby avoiding the need to move the undersurface detector 10 multiple times during detection, thereby affecting the detection efficiency.

[0031] In some embodiments, the undersurface detector protection device further comprises a gas supply device 3 and a dust removal device 4. The gas supply device 3 is arranged outside the protective shell 1, thereby avoiding affecting the normal work of the undersurface detector 10 when the gas supply device 3 is started. The dust removal device 4 is arranged on the first wall body 14 and above the window 13. The dust removal device 4 can be a stainless steel air knife for blowing off floating dust and other impurities on the window 13, thereby maintaining the cleanliness of the window 13 as a whole, so that the undersurface detector 10 can shoot high-definition images. The gas supply device 3 is connected to the dust removal device 4 for providing power for the dust removal device 4. The fixing seat 2 comprises a cooling pipeline 5, and the outlet 51 of the cooling pipeline 5 is arranged towards the undersurface detector 10. The gas supply device 3 is connected to the cooling pipeline 5 for cooling the undersurface detector 10, thereby avoiding the influence of high temperature of the working environment on the undersurface detector 10 or the influence of heating on the shooting speed of the undersurface detector 10 when working for a long time, thereby affecting the subsequent processing precision of the billet.

[0032] It can be understood that the gas supply device 3 can provide compressed air, nitrogen and other media to realize the functions of blowing off the window and cooling the undersurface detector. The gas supply device 3 can be provided with two or more, corresponding to the dust removal device 4 and the cooling pipeline 5, thereby realizing the independent opening of the dust removal device 4 or the cooling pipeline 5 according to actual needs.

[0033] Further, when the lower surface detector 10 is provided with multiple, the dust removal device 4 and the outlet 51 of the cooling pipeline 5 are also provided with multiple, corresponding to the lower surface detector 10 one by one, and the working temperature and the shooting angle of the lower surface detector 10 are always guaranteed to have no sundries that may affect the shooting detection, thereby guaranteeing the processing precision of the billet.

[0034] In some embodiments, the lower surface detector protection device further comprises a cover plate 11 arranged at the intersection of the cover plate 11 and the first wall body 14, and the dust removal device 4 is arranged below the cover plate 11 to avoid iron filings and other sundries falling from the steel processing from damaging the dust removal device 4 and affecting the cleaning of the surface dust and oil of the view window 13.

[0035] In some embodiments, the lower surface detector protection device further comprises a hinged structure 6 arranged between the cover plate 11 and the accommodating plate 12, and the cover plate 11 is rotationally connected to the accommodating plate 12. The cover plate 11 and the protection shell 1 are hingedly opened and closed, and can achieve a large opening angle, which is convenient for installing and maintaining the structure in the protection shell 1 and adjusting the lower surface detector 10.

[0036] In some embodiments, the lower surface detector protection device further comprises a sealing strip 7 installed at the connection between the cover plate 11 and the accommodating plate 12, wherein the edges of the cover plate 11 are all provided with the sealing strip 7, so that the upper part of the lower surface detector protection device has a certain heat insulation and the protection shell 1 has a certain sealing property, thereby preventing the entry of steel slag and dust into the box body and causing damage to the internal lower surface detector and the fixing seat 2.

[0037] It can be understood 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 inside, but due to the influence of high temperature, the pressure in the protection shell 1 will become larger and larger. In some embodiments, the accommodating plate 12 is further provided with a pressure relief valve 8, which opens to release the gas in the protection shell 1 when the pressure in the protection shell 1 is greater than a preset value, thereby maintaining the stable air pressure in the protection shell 1. The pressure relief valve 8 further comprises a noise reduction element (not shown in the figure) to reduce the noise when the pressure relief valve 8 is opened, thereby improving the use performance.

[0038] Further, in order to ensure that the pressure relief valve 8 does not affect the air supply device 3 when it is opened, in some embodiments, the pressure relief valve 8 is arranged on the second wall body 15 away from the air supply device 3, so as to avoid that the high-temperature gas rushes to the air supply device 3 when the pressure relief valve 8 is opened, thereby causing damage to the air supply device 3.

[0039] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
