[0044] The present invention will be further described below with reference to the accompanying drawings.

[0046] Overall concept of the technical solution:
[0047] This utility model addresses the problems of low efficiency and poor accuracy in measuring furnace roller elevation in metallurgical production lines by proposing a dedicated device based on three-point positioning of a semi-circular support and self-calibration of a vertical support (such as...). Figure 1 , 2 (As shown). The core design logic is:
[0048] 1. The semi-circular bracket achieves rapid and stable installation by using the three-point positioning principle (top midpoint + both end points) through surface contact between the inner arc surface and the outer diameter of the furnace roller (not the traditional point contact);
[0049] 2. The vertical support integrates a horizontal calibration function, eliminating errors caused by manual ruler adjustment through a mechanical adjustment mechanism;
[0050] 3. Modular scale connection provides multiple fixing solutions, covering scenarios such as conventional measurement, high temperature environment, and vibration conditions. Example 1
[0051] This embodiment provides a furnace roller elevation measuring device, such as... Figure 1 As shown, it includes a semi-circular bracket 1, a vertical bracket 2, and a scale connecting device 3;
[0052] The inner surface of the semi-circular support 1 is in contact with the arc of the furnace roller;
[0053] The vertical bracket 2 is located at the midpoint of the outer surface of the semicircular bracket 1 and is fixedly connected to the semicircular bracket 1 perpendicular to the midpoint of the outer surface of the semicircular bracket 1.
[0054] The ruler connecting device 3 is installed on the vertical support 2 and is used for rigid fixed connection between the ruler 5 and the vertical support 2.
[0055] Implementation principle: By fitting the inner surface of the semi-circular bracket 1 with the curvature of the furnace roller, the vertical bracket 2 is quickly positioned, and the scale 5 is quickly straightened, reducing the number of operators and the operation time, thereby improving the efficiency of furnace roller elevation measurement. Example 2
[0056] Based on the same design principle as in Embodiment 1, this embodiment provides a furnace roller elevation measuring device, including a semi-circular bracket 1, a vertical bracket 2, and a scale connecting device 3;
[0057] The semi-circular bracket 1 is made of flat steel with a thickness of ≥5mm bent into an arc segment of 150°~180°. The curvature of the inner surface matches that of the furnace roller, and the contact surface is provided with anti-slip texture or replaceable pads.
[0058] Vertical bracket 2 is a rigid support structure fixed at the midpoint of semicircular bracket 1. It is used to transmit the elevation measurement benchmark and can integrate horizontal calibration function.
[0059] The ruler connecting device 3 is a mechanism that rigidly fixes the steel ruler to the vertical support 2, including mechanical clamping, magnetic attraction, and slot types.
[0060] By fitting the inner surface of the semi-circular bracket 1 with the curvature of the furnace roller, the vertical bracket 2 can be quickly positioned, and the scale 5 can be quickly straightened, reducing the number of operators and the operation time, thereby improving the efficiency of furnace roller elevation measurement.
[0061] like Figure 2 As shown, a level bubble level 4 is also installed on the vertical support 2 to adjust the direction of the vertical support 2 to be perpendicular to the horizontal plane. The level bubble level 4 can assist the vertical support 2 in leveling, effectively improving measurement efficiency.
[0062] Preferably, the horizontal bubble meter 4 includes two horizontal bubble meters 4 connected perpendicularly to the vertical support 2; both horizontal bubble meters 4 are arranged in a plane perpendicular to the length direction of the vertical support 2. The two perpendicular horizontal bubble meters 4 facilitate faster adjustment of the verticality of the vertical support 2, effectively improving the accuracy of support adjustment.
[0063] Preferably, the inner surface of the semi-circular support 1 is provided with a rubber pad. The rubber pad helps to increase the coefficient of friction, allowing the semi-circular support 1 to be better fixed to the surface of the furnace roller.
[0064] Preferably, the main structure is: a φ380mm semi-circular bracket 1 is made by bending flat steel (matching the radius of the furnace roller surface), and a 200mm vertical flat steel is welded to the top to form a stable support frame.
[0065] The semicircular bracket 1 is formed by bending flat steel with a thickness greater than 5mm and a width range of 40-60mm into a semicircle with an angle of 150°-180°.
[0066] The vertical support 2 is formed by straightening flat steel with a length of 150mm-300mm, a thickness greater than 5mm, and a width range of 40-60mm; preferably, it is formed by bending flat steel with a thickness of 5mm and a width range of 50mm into a semicircle with an angle of 180°; the height of the flat steel of the vertical support 2 can be appropriately increased or decreased according to the measuring range of the steel ruler used.
[0067] The vertical support 2 is welded to the midpoint of the outer surface of the semi-circular support 1. Preferably, it is made of straightened flat steel with a length of 200mm, a thickness of 5mm, and a width of 50mm.
[0068] Experimental results show that the semicircular support 1 and vertical support 2 within this numerical range are easy to manufacture and operate, and can effectively improve measurement efficiency.
[0069] The semi-circular bracket 1 is optimized by cold-bending 50mm wide × 5mm thick Q235 flat steel, achieving a bending strength ≥235MPa and a 3-fold increase in service life. The vertical bracket 2 is designed to optionally accommodate a horizontal bubble meter 4. Figure 2 Alternatively, a simple positioning slot can be used to balance high precision requirements with low-cost scenarios.
[0070] Preferably, the ruler 5 is a steel ruler.
[0071] Ruler 5 fixing: The steel ruler is rigidly fixed to the bracket to ensure that the ruler 5 has zero wobbling (steel ruler fixing methods: ① bolt fixing, ② magnetic fixing, ③ clamp fixing, ④ binding fixing, ⑤ slot fixing, ⑥ adhesive fixing, etc., and the appropriate fixing method can be selected according to the actual site conditions).
[0072] Optional, such as Figure 1 and Figure 2 As shown, the scale connecting device 3 includes a bolt hole at the top of the vertical support 2, a connecting hole at the bottom of the scale 5, and a bolt passing through the bolt hole and the connecting hole. The bolt fixing is simple and convenient, and the scale is detachable, ensuring zero wobble of the scale 5 and improving measurement accuracy.
[0073] Optionally, the scale connecting device 3 includes strong magnets respectively disposed on both sides of the contact surface between the vertical support 2 and the scale 5. Magnetic fixation is simple and convenient, easy to operate, and helps improve work efficiency.
[0074] Preferably, a groove matching the shape of the ruler 5 and guiding the top of the vertical support 2 is provided near the strong magnet on the vertical support 2. The groove is parallel to the length direction of the vertical support 2, thereby vertically placing the ruler 5, which is beneficial for vertical verification and saves calibration time.
[0075] Optionally, the scale connecting device 3 includes a T-shaped flange fixedly disposed at the bottom of the scale 5 and a T-shaped groove disposed at the top of the vertical support 2, which matches the shape of the T-shaped flange. The T-shaped flange and the T-shaped groove facilitate the precise positioning and quick assembly / disassembly of the scale 5 and the vertical support 2, effectively improving measurement efficiency.
[0076] The operation process of this utility model includes:
[0077] ① Installation and positioning: Insert the semi-circular bracket 1 into the furnace roller;
[0078] ② Fixing the scale 5: Connect the scale 5 to the vertical support 2 through the scale connecting device 3, and straighten it through the horizontal bubble meter 4;
[0079] ③ Quick measurement: Read the 5th mark on the scale, and the measurement time for a single point is ≤1 minute.
[0080] In addition, it is important to note that:
[0081] In high-temperature areas (≤600℃), the semi-circular bracket 1 should be made of 310S stainless steel, and the rubber pad should be removed.
[0082] The high-vibration operating condition scale 5 adopts a double fixation of bolts and binding to resist vibration frequency ≥50Hz.
[0083] For narrow spaces, a foldable vertical bracket 2 is recommended, with an unfolding / folding time of ≤15 seconds.
[0084] Application prospects and economic benefits forecast of this utility model:
[0085] Economic benefits: Optimizing the roller surface elevation measurement work from 5 people working 8 hours to 3 people working 4 hours, and calculating at 100 yuan per person per hour, the resulting benefit is (5 people - 3 people) × (8 hours - 4 hours) × 100 yuan / person ⋅ hour = 800 yuan.
[0086] Other benefits:
[0087] 1. Reduced working time by 50%: Traditional methods require 4 people to work together for 8 hours, while this device only requires 2 people to complete the task in 4 hours, which greatly shortens the time that workers spend in a first-level confined space and reduces the risk of heatstroke and misoperation in high-temperature and confined environments.
[0088] 2. Completely eliminate the hidden dangers of manual support for ruler 5: Replace manual support with a rigid fixed structure to avoid accidents such as injury or equipment damage caused by ruler 5 slipping.
[0089] 3. Improved accuracy: Mechanical fixation ensures zero offset of the scale 5, reducing rework caused by measurement errors and indirectly reducing the frequency of repeated entry into the confined space.
