[0002] A continuous casting machine is an industrial equipment used to continuously cast high-temperature molten steel into ingots with certain cross-sectional shapes and dimensions. This process involves multiple key equipment, including steel casting equipment, continuous casting machine main equipment, cutting area equipment, ingot rod collection and conveying equipment, etc. The electromechanical and hydraulic integration of these equipment constitutes the core of the continuous casting machine. Continuous casting machines can be divided into vertical, vertical-bending, arc-shaped, ultra-low-head (elliptical), horizontal, wheel-type and other types according to their structural appearance. At the same time, they can also be divided into slabs, small square billets, large square billets and other types according to the casting cross-section. Continuous casting technology is widely used. It not only occupies an important position in steel production, but also has obvious advantages over traditional die casting technology due to its short production process, low energy consumption, low cost, high productivity and easy automation. Therefore, it has been rapidly popularized around the world.

[0003] Continuous casting machine segments have certain jagged roll gap defects, which seriously interfere with the management of the cold roll gap. The size of the roll gap directly affects the quality and dimensional accuracy of the castings. During the continuous casting process, precise control of the roll gap value can ensure that the castings meet the required size and shape requirements. In addition, measuring and controlling the roll gap is also a key link in ensuring the efficient operation of the continuous casting machine. In actual operation, the roll gap value will vary depending on the specific model of the continuous casting machine, the process requirements, and the specific needs of the casting. For continuous casting machine operators, accurately measuring and controlling the roll gap value is a critical skill and responsibility.

[0029] See also Figure 1-6The present invention provides a technical solution: a device for measuring the displacement of the upper and lower frames of the fan-shaped segments of a continuous casting unit, comprising a fan-shaped segment upper frame 1, a vertical detection mechanism and a horizontal detection mechanism. A fan-shaped segment lower frame 2 is provided below the bottom of the fan-shaped segment upper frame 1. The vertical detection mechanism comprises a measuring frame 3, a rectangular plate 4, a side plate 5, a sliding rod 6, a first rectangular rod 7, a sliding rod 8, a second rectangular rod 9 and a laser ranging sensor 26. The number of measuring frames 3 is two and they are fixedly connected to the opposite surfaces of the fan-shaped segment upper frame 1 and the fan-shaped segment lower frame 2 respectively. The number of rectangular plates 4 is two. And are respectively fixedly connected to the corresponding surface of the measuring frame 3, the side plate 5 is fixedly connected to the corresponding surface of the rectangular plate 4, the number of sliding rods 6 is two and both are fixedly connected to the side plate 5, the first rectangular rod 7 is slidably connected to the outer surface of the sliding rod 6 set on the bottom measuring frame 3, the second rectangular rod 9 is slidably connected to the outer surface of the sliding rod 6 set on the top measuring frame 3, the sliding rod 8 is fixedly connected to the bottom of the second rectangular rod 9, the sliding rod 8 is slidably connected to the inside of the first rectangular rod 7, and the surface of the first rectangular rod 7 is provided with a slide groove 15 on both sides, and both sides of the sliding rod 8 are fixed A slider 16 is connected, the slider 16 is located inside the slide groove 15 and is slidably connected to the slide groove 15, and the laser ranging sensor 26 is fixedly connected to the surface of the measuring frame 3. The arrangement of 7, 8 and 9 enables the device to move in the vertical direction. When the upper frame 1 and the lower frame 2 of the sector segment move vertically, the sliding rod 8 slides inside the first rectangular rod 7. The arrangement of the slide groove 15 and the slider 16 makes the sliding of the sliding rod 8 more stable. Since the upper frame 1 of the sector segment is located at the top of the lower frame 2 of the sector segment, the vertical distance between the upper frame 1 and the lower frame 2 of the sector segment can be The laser diode on the laser ranging sensor 26 is directly aimed at the bottom of the fan-shaped segment upper frame 1 to emit laser pulses. After being reflected by the target, the laser is scattered in all directions. Part of the scattered light returns to the sensor receiver to obtain displacement data, thereby realizing the measurement of vertical displacement with high measurement accuracy. When horizontal displacement occurs between the fan-shaped segment upper frame 1 and the fan-shaped segment lower frame 2, the first rectangular rod 7 and the second rectangular rod 9 slide on the surface of the sliding rod 6 respectively. The setting of this structure can avoid the horizontal displacement between the fan-shaped segment upper frame 1 and the fan-shaped segment lower frame 2 from being hindered, making the structure more reasonable.

[0030] Furthermore, the horizontal detection mechanism includes a first mounting plate 10, a first movable plate 11, a second mounting plate 12, a second movable plate 13, a mounting seat 17, a pressure sensor 18, a limit top plate 19, a limit bottom plate 20, a telescopic rod 21, a spring 22 and a pressure plate 23. The first mounting plate 10 and the second mounting plate 12 are both fixedly connected to the top of the measuring frame 3 provided on the lower frame 2 of the fan segment, and the first movable plate 11 and the second movable plate 13 are both fixedly connected to the bottom of the measuring frame 3 provided on the upper frame 1 of the fan segment. There are two mounting seats 17, which are respectively fixedly connected to the corresponding first mounting plates 10 and On the surface of the second mounting plate 12, there are two pressure sensors 18 and they are fixedly connected to the corresponding mounting seats 17 respectively. There are multiple limit top plates 19 and they are fixedly connected to the surfaces of the first movable plate 11 and the second movable plate 13 respectively. The number of limit bottom plates 20 is the same as that of the limit top plates 19 and they are fixedly connected to the surfaces of the first movable plate 11 and the second movable plate 13 respectively. The limit bottom plate 20 is located below the limit top plate 19. There are multiple telescopic rods 21 and they are fixedly connected to the surfaces of the first movable plate 11 and the second movable plate 13 respectively. The pressure plate 23 is fixedly connected to the telescopic rod 21. The number of springs 22 is There are two springs 22 that are fixedly connected to the corresponding pressure plates 23. The ends of the two springs 22 away from the pressure plates 23 are fixedly connected to the first movable plate 11 and the second movable plate 13 respectively. When horizontal displacement occurs between the upper frame 1 and the lower frame 2 of the sector segment, there are two situations. If the first movable plate 11 and the first mounting plate 10 are close to each other, the first movable plate 11 drives the pressure plate 23 to move and applies pressure to the pressure sensor 18 through the action of the spring 22. After receiving the pressure, the pressure sensor 18 sends a signal and calculates the deformation x of the spring 22 by Hooke's law F=kx (the spring constant k of the spring 22 is shown in FIG. The horizontal displacement distance between the upper segment frame 1 and the lower segment frame 2 can be monitored. Since the pressure plate 23 is slidably connected to the corresponding limit bottom plate 20 and limit top plate 19 through the limit block 25 and the telescopic rod 21, the influence of gravity on the spring 22 can be reduced, thereby reducing the calculation error. If the second movable plate 13 and the second mounting plate 12 are close to each other, the displacement distance between the upper segment frame 1 and the lower segment frame 2 can be calculated in the same way. The setting of this structure can realize the use of the spring 22 in a compressed state for measurement when measuring the displacement, which facilitates the acquisition of detection results.

[0031] Secondly, the surfaces of the first rectangular rod 7 and the second rectangular rod 9 are provided with openings 14 that are adapted to the slide rod 6. The pressure sensor 18 is in contact with the pressure plate 23 and the pressure sensor 18 is located at the center of the pressure plate 23. The shape of the mounting seat 17 is trapezoidal. The top and bottom of the pressure plate 23 are fixedly connected to the limiting block 25. The limiting block 25 is slidably connected to the corresponding limiting top plate 19 and the limiting bottom plate 20. The surfaces of the limiting top plate 19 and the limiting bottom plate 20 are provided with limiting grooves 24 for the limiting block 25 to slide. The pressure plate 23 and the slide rod 6 are both made of 304 stainless steel with a smooth surface and relatively hardness, which can reduce friction.

[0032] Working principle: When the upper frame 1 and the lower frame 2 of the sector segment move in the vertical direction, the sliding rod 8 slides inside the first rectangular rod 7. The setting of the slide groove 15 and the slider 16 makes the sliding of the sliding rod 8 more stable. Since the upper frame 1 of the sector segment is located at the top of the lower frame 2 of the sector segment, the vertical distance between the upper frame 1 and the lower frame 2 of the sector segment can be directly measured by the laser diode on the laser ranging sensor 26. The laser pulse is emitted at the bottom of the upper frame 1 of the sector segment. After being reflected by the target, the laser is scattered in all directions. Part of the scattered light returns to the sensor receiver to obtain displacement data, thereby realizing the measurement of vertical displacement. When horizontal displacement occurs between the upper frame 1 and the lower frame 2 of the sector segment, the first movable plate 11 drives the pressure plate 23 to move and applies pressure to the pressure sensor 18 through the action of the spring 22. The pressure sensor 18 sends a signal after receiving the pressure, thereby monitoring the horizontal displacement distance between the upper frame 1 and the lower frame 2 of the sector segment.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
