[0002] Laser sensor is a sensor that uses laser technology for measurement. It consists of a laser, a laser detector and a measuring circuit. When using a laser sensor to measure the roll shape of a roll, it uses the principle of laser reflection and ranging. When the laser sensor emits a laser beam to the roll surface, the reflected light on the roll surface is reflected into the laser sensor. After wavelength recognition and calculation, the actual position of the roll surface is obtained. By comparing the difference between the initial position of the roll and the real-time measured position, the deformation and wear of the roll during use can be obtained.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) During the real-time measurement process, the air cooling device of the present invention can inject cold air into the protective housing and the heat insulation board one through the ventilation pipe two and the ventilation port two. The cold air cools down the laser sensor in the heat insulation board one. At the same time, the cooling fan in the cooling device blows the cold air to the cooling board two through the heat dissipation port two, and cools down the bottom of the laser sensor through the heat dissipation port three and the heat dissipation port one, thereby completely and thoroughly cooling the laser sensor, which can solve the problem that the bottom cannot be cooled by blowing air in the prior art. After cooling, the wind is discharged through the ventilation port one and the ventilation pipe one, thereby reducing the temperature inside the protective housing to the maximum extent, ensuring that the laser sensor measures at the specified operating temperature, improving the performance of the laser sensor, and reducing the influence of the external temperature on the laser sensor; preventing the technical problem of deviation in the measurement result of the laser sensor due to excessive temperature; at the same time, because the ventilation pipe one and the ventilation pipe two are staggered, it can ensure that the cold air fills the entire shell, which can effectively avoid overheating of the sensor in a high temperature environment and affect the detection; (2) The first and second insulation boards of the present invention are composite aerogel insulation boards. Since the composite aerogel insulation boards are a new generation of fire-resistant insulation materials synthesized by wet method and made of silica aerogel with ultra-low thermal conductivity, they can work at 900°C for a long time and have multiple advantages such as light weight, high strength, processability, and waterproofness. They can greatly reduce the impact of excessive roller temperature on the performance of laser sensors and also have a waterproof effect. (3) In the present invention, a polycarbonate transparent plate (PC plate) is installed on the optical path. The polycarbonate transparent plate has excellent heat resistance and ultra-low thermal conductivity, and has extremely strong light transmittance. At the same time, polycarbonate is hydrophobic. A nano coating is sprayed on the outside of the polycarbonate, which can reduce the measurement error caused by the refraction of water.

[0032] The cooling plate 801 is provided with a plurality of heat dissipation openings 805, the cooling rack 802 is provided with a plurality of heat dissipation openings 803, and one side of the cooling rack 802 is also provided with a cable opening 804 matching the cable plug interface 102 and the cable opening 108. The cable is used to supply power to the motor 807 via the cable plug interface 102, the cable opening 108 and the cable opening 804.
[0033] The position adjustment unit includes a cooling plate 601, bolts 602, guide rails 603 and a heat dissipation port 604. The cooling plate 601 is detachably mounted on the cooling frame 802 by a plurality of bolts 602. The cooling plate 601 is arranged above the cooling plate 801. Two guide rails 603 are arranged on the cooling plate 601 at intervals. Mounting plates 605 are fixedly mounted on both ends of both sides of the cooling plate 601. A plurality of heat dissipation ports 604 are provided on the cooling plate 601. Screws 606 and sliders 607 are arranged on both sides of the cooling plate 601. The screws 606 are rotatably mounted on the mounting plate 605. A rotating ring 608 is fixedly mounted on the end of each screw 606. Two sliders 607 are respectively fixedly mounted on both sides of the laser sensor assembly. The sliders 607 and the screws 606 are connected by threads.
[0034] The laser sensor assembly includes a laser sensor 701, two sliding frames 704 are detachably arranged at intervals below the laser sensor 701, the sliding frames 704 match the guide rail 603, the sliding frames 704 are slidably connected to the guide rail 603, a power supply port 702 is arranged at one end of the laser sensor 701 close to the cable plug interface 2 103, a laser head 703 is arranged on the side of the laser sensor 701 facing the light port 110 and the optical path channel 401, the laser head 703 is coaxially arranged with the light port 110 and the optical path channel 401, and two sliders 607 are fixedly installed on both sides of the laser sensor 701 respectively.
[0035] The working principle of the present invention is: When it is necessary to adjust the distance from the laser head 703 to the light opening 110 and the optical path channel 401 (adjust according to the test results during actual use), the two rotating rings 608 are rotated at the same time. By setting two screws 606 and two rotating rings 608, it is possible to prevent the position of the laser head 703 from being deviated due to the misoperation of rotating one of the rotating rings 608. When the two rotating rings 608 are rotated, the rotating ring 608 drives the screw 606 to rotate. When the screw 606 rotates, it drives the laser sensor 701 to move through the slider 607. The laser sensor 701 drives the laser head 703 to move, thereby adjusting the distance from the laser head 703 to the light opening 110 and the optical path channel 401 to ensure the effect of the laser sensor 701 on the online measurement of the roll shape of the roller.
[0036] When the laser sensor 701 needs to be cooled during real-time measurement, the air cooling device injects cold air into the protective housing 101 and the heat insulation board 104 through the ventilation pipe 2 302 and the ventilation port 2 109. The cold air cools the laser sensor 701 in the heat insulation board 104. At the same time, the output shaft of the motor 807 drives the cooling fan 808 to rotate. When the cooling fan 808 rotates, the cold air is blown to the cooling board 2 801 through the heat dissipation port 2 803, and the bottom of the laser sensor 701 is cooled through the heat dissipation port 3 805 and the heat dissipation port 1 604, so that the laser sensor 701 can be cooled. The optical sensor 701 is completely and thoroughly cooled, which can solve the problem in the prior art that it is impossible to cool the bottom by blowing air. After cooling, the wind is discharged through the vent 106 and the ventilation pipe 301, thereby ensuring that the laser sensor 701 can always maintain a suitable temperature and preventing the technical problem of deviation in the measurement result of the laser sensor 701 due to excessive temperature. At the same time, since the ventilation pipe 1 301 and the ventilation pipe 2 302 are staggered, it can be ensured that cold air fills the entire shell, which can effectively avoid overheating of the sensor in a high temperature environment and affect detection.
[0037] Since a polycarbonate transparent plate (PC plate) is installed on the optical path channel 401, the polycarbonate transparent plate has excellent heat resistance and ultra-low thermal conductivity, and has extremely strong light transmittance. At the same time, polycarbonate is hydrophobic, and a nano-coating is sprayed on the outside of the polycarbonate, which can reduce the measurement error caused by the refraction of water. At the same time, it can also reduce the water mist caused by the temperature difference between the inside and outside of the protective shell 101 and the insulation board 104, thereby ensuring the detection effect of the laser sensor 701.
[0038] In actual use, the present invention can effectively protect the water vapor, dust and the like outside the protective shell 101 by setting a sealing gasket between the sealing track plate 105 and the sealing groove 202, and designing the sealing plugs at the cable plug interface 102, the cable plug interface 2 103, the cable port 1 107 and the cable port 2 108, and the sealing gasket has no leakage, thereby effectively extending the service life of the protective shell 101 and the sealing gasket. The present invention improves the protection level of the laser sensor 701, has high protection, strong practicality, and is easy to install, thereby improving the accuracy of online measurement of the roller shape and reducing measurement errors.
