Description

Technical Field

[0001] This invention relates to the field of measuring instrument technology, and more specifically, to an installation device and method for a point-type pyrometer. Background Technology

[0002] In heavy industrial steel rolling production lines, point-type pyrometers, as key temperature measuring devices, are widely used for monitoring the surface temperature of strip steel. Their workflow forms a complete technical closed loop: first, a high-precision optical system captures the infrared energy radiated by the steel; then, a dedicated detector converts the light energy into a recognizable electrical signal; after filtering, amplification, and emissivity compensation correction by the signal processing module, the real-time temperature of the strip steel is accurately calculated, and finally, the data is fed back to the production control system, providing core support for parameter optimization and quality control in the hot rolling process. The core competitiveness of this equipment lies in two main aspects: first, its non-contact measurement mode perfectly adapts to the high-speed movement of the strip steel, avoiding the damage to the steel surface quality and the equipment itself caused by contact measurement; second, it adopts a special protective structure design to effectively ensure the accuracy and stability of temperature data acquisition in the harsh environment of high temperature, dust, and moisture at the hot rolling site, making it an indispensable key piece of equipment in the steel rolling production process.

[0003] However, the existing installation method for point-type pyrometers has significant drawbacks, severely restricting on-site maintenance efficiency. The current installation structure involves the pyrometer housing being securely connected to a steel plate with four large screws. The steel plate is then welded to a custom-made clamp, which is finally fixed to a crossbeam on the production line with four bolts. In actual production, the continuous and intense vibrations generated during the steel rolling process easily cause the point-type pyrometer's measurement position to shift, requiring periodic or emergency adjustments. However, these adjustments must follow a strict disassembly sequence: first, loosen the four bolts connecting the clamp to the crossbeam, then adjust the lateral position of the entire pyrometer housing on the crossbeam as needed, or fine-tune the relative angle between the steel plate and the clamp to achieve vertical adjustment.

[0004] More importantly, the high-temperature environment and high concentration of moisture at the hot rolling mill cause rapid corrosion of metal components. All screws in the installation structure can rust and seize up within a short time, making them difficult to disassemble. Forced operation can also cause secondary failures such as stripped screws and deformed clamps. Each repositioning requires maintenance personnel to spend a significant amount of time cleaning rust and prying up rusted components, often requiring multiple people and several hours to complete, severely impacting production schedules. The inefficiency of traditional installation methods is even more pronounced in scenarios involving sudden temperature anomalies and the need for emergency adjustments to measurement points, failing to meet the demand for rapid adjustments and potentially leading to product quality fluctuations or even production accidents due to temperature monitoring failures.

[0005] As the steel rolling industry transforms towards intelligent and efficient operations, traditional, labor-intensive, and time-consuming equipment maintenance methods are gradually being phased out, placing higher demands on the convenience, flexibility, and efficiency of equipment maintenance. From the functional requirements of point-type pyrometers, as core equipment for temperature monitoring, they not only need to ensure data accuracy but also possess rapid adjustment capabilities to adapt to immediate needs in scenarios such as emergency measurements and process switching, achieving the maintenance goal of "adjustment completed by a single person in a short time." Therefore, developing a point-type pyrometer installation device that differs from existing installation structures and enables convenient, quick, safe, and effective adjustments has become an industry necessity.

[0006] This device, through optimized fixed structure design, can significantly simplify the adjustment process, avoid rusting problems, significantly reduce maintenance manpower and time costs, effectively improve on-site maintenance efficiency, and ultimately achieve cost reduction and efficiency improvement in the steel rolling production process, providing equipment-level support for the intelligent upgrading of steel rolling production lines.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1

[0036] from Figure 1-3As can be seen, the installation device of the point-type pyrometer in this embodiment includes a housing 1, a cover 2 is provided on the upper part of the housing 1, an air duct 10 is provided on the lower part of the housing 1, an internal pyrometer 4 is provided inside the housing 1, and an internal rubber gasket 5 is also provided on the inner bottom of the housing 1. An installation hole 501 is opened in the middle of the internal rubber gasket 5, and the lower end of the internal pyrometer 4 passes through the installation hole 501 and is placed inside the housing 1.

[0037] Multiple sets of adjustment devices are provided at intervals on the outer periphery of the housing 1. The adjustment devices include a front adjustment device 6, a rear adjustment device 7, a left adjustment device 8, and a right adjustment device 9.

[0038] One end of the front adjustment device 6, the rear adjustment device 7, the left adjustment device 8, and the right adjustment device 9 extends into the housing 1 and contacts the surface of the built-in pyrometer 4.

[0039] The cover 2 is engaged with the housing 1 by a buckle 3. There are two sets of buckles 3, which are spaced apart on both sides of the cover 2. The cover 2 can be removed by opening the buckle 3, and then the built-in pyrometer 4 can be pulled out from the housing 1 for replacement. The internal space of the housing 1 is slightly larger than the diameter of the built-in pyrometer 4, which allows the bolts of the adjustment device to move outward.

[0040] The housing 1 is fixed to the crossbeam 11 and secured with screws.

[0041] The built-in rubber gasket 5 is elastic, and the built-in pyrometer 4 can be tilted at a small angle within the mounting hole 501. The diameter of the mounting hole 501 is larger than the diameter of the air duct 10, ensuring that the viewing angle of the built-in pyrometer 4 is uninterrupted when tilting. The diameter and length of the air duct 10 need to be calculated and precisely set to ensure that the built-in pyrometer 4 has a viewing angle that covers the entire roller conveyor gap when adjusting.

[0042] The front adjustment device 6 includes a front fixing block 601, a front adjusting bolt 602 is internally threaded onto the front fixing block 601, and a front adjusting cam 603 is provided on one end of the front adjusting bolt 602.

[0043] The rear adjustment device 7 includes a rear fixing block 701, a rear adjusting bolt 702 is internally threaded onto the rear fixing block 701, and a rear adjusting cam 703 is provided on one end of the rear adjusting bolt 702.

[0044] The left adjustment device 8 includes a left fixing block 801, a left adjustment bolt 802 is internally threaded onto the left fixing block 801, and a left adjustment cam 803 is provided on one end of the left adjustment bolt 802.

[0045] The right-side adjustment device 9 includes a right-side fixing block 901, a right-side adjusting bolt 902 is internally threaded onto the right-side fixing block 901, and a right-side adjusting cam 903 is provided on one end of the right-side adjusting bolt 902.

[0046] One end of the front adjusting bolt 602, the rear adjusting bolt 702, the left adjusting bolt 802, and the right adjusting bolt 902 extends into the housing 1 and contacts the surface of the built-in pyrometer 4.

[0047] The front fixing block 601, the rear fixing block 701, the left fixing block 801, and the right fixing block 901 are welded to the outer surface of the housing 1 respectively, are externally sealed, and are on the same horizontal line. The front fixing block 601, the rear fixing block 701, the left fixing block 801, and the right fixing block 901 have nut thread hole shapes inside, and the screws adopt a fine thread design to ensure that the bolts can be fixed well when not moving, and also to make the adjustment relatively smooth and orderly.

[0048] The ends of the adjusting bolts are equipped with adjusting cams, which can be easily turned and adjusted by hand, allowing the bolts to move freely under manual operation;

[0049] Example 2

[0050] from Figure 1-3 As can be seen, this embodiment describes a method for installing a point-type pyrometer:

[0051] When the measurement position needs to be adjusted, simply open the latches 3 on the left and right sides of the cover 2, remove the cover 2, and observe the deviation of the current measurement position from the center point of the roller conveyor through the eyepiece behind the pyrometer. Observe the position of the pyrometer measurement burn spot 12 generated by the built-in pyrometer 4 relative to the first roller conveyor 13 and the second roller conveyor 14.

[0052] The first roller table 13 and the second roller table 14 are two roller tables for the finishing section of the hot rolling field, and the gap between the roller tables is 110mm. The size of the pyrometer measuring the burnt spot 12 is generally adjusted to a diameter of 30mm. It must be ensured that it is in the middle of the gap between the roller tables in order to measure the temperature of the center line of the strip steel normally and effectively.

[0053] Loosen the front adjusting bolt 602, the rear adjusting bolt 702, the left adjusting bolt 802, and the right adjusting bolt 902 to adjust the actual installation position of the built-in pyrometer 4.

[0054] By adjusting while looking through the eyepiece, the pyrometer measurement point was finally adjusted to the center of the roller conveyor gap. After adjustment, all the front adjusting bolts 602, rear adjusting bolts 702, left adjusting bolts 802, and right adjusting bolts 902 were tightened and pressed against the built-in pyrometer 4 to ensure that the position was fixed, thus completing the adjustment.

[0055] by Figure 1 For example, from the perspective of:

[0056] When the pyrometer's measured focal spot 12 has illuminated the second roller conveyor 14, it means the overall frame is too far forward, and the measuring point needs to be adjusted slightly backward. Therefore, the front adjustment device 6 and the rear adjustment device 7 need to be adjusted. Tighten the front adjustment bolt 602 slightly inward into the housing 1 and the rear adjustment bolt 702 slightly outward, keeping the other bolts unchanged. As a rotating axis, under the action of force, the built-in pyrometer 4 will move backward, and the built-in rubber gasket 5 will become elastic, slightly contracting at the front. By adjusting while looking through the eyepiece, the pyrometer measuring point can be easily adjusted to the center of the roller conveyor gap. After adjusting all the bolts, keep the built-in pyrometer 4 tightly closed to ensure its position is fixed, thus completing the adjustment. The principle for adjusting other directional offsets is the same. The above operation is simple and clear, providing convenience for instrument maintenance.

[0057] This invention discloses a special installation device for point-type pyrometers that differs from traditional structures, enabling rapid and accurate calibration of point-type pyrometers. This device has the core advantages of convenient operation and reliable safety, which can significantly shorten the time required for pyrometer calibration. Using this technical solution to carry out point-type pyrometer calibration work can significantly reduce operating costs and improve overall operation and maintenance efficiency.

[0058] To address the specific needs of on-site operating conditions, this invention develops a point-type pyrometer installation device adapted to the field environment. This device not only enables rapid calibration of the pyrometer but also effectively reduces personnel input and time consumption. While improving equipment operation and maintenance efficiency, it also enhances the practical maintenance capabilities of inspection personnel for instrumentation equipment, providing technical support for the stable operation of on-site instruments.

[0059] Field verification has shown that this device significantly simplifies the calibration process of point-type pyrometers, making the operation logic clearer and the steps more intuitive. With this device, the cumbersome bracket disassembly work of traditional methods is eliminated, allowing a single person to independently complete all maintenance and calibration work for the pyrometer. Previously, pyrometer replacement required advance coordination of personnel and work schedules, resulting in high labor and time costs; this device enables single-person operation, making it convenient and efficient, and significantly reducing operation time. Simultaneously, the built-in design of the core adjusting bolt isolates it from external environmental corrosion, effectively preventing bolt rusting and jamming, completely solving the maintenance pain points of traditional structures. Furthermore, the device's simple overall structure and ease of maintenance further save significant manpower and resources, achieving remarkable cost reduction and efficiency improvement.

[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
