Description

Technical Field

[0001] This utility model relates to a measuring device for the arc of a continuous casting machine, belonging to the field of continuous casting machine arc measurement technology. Background Technology

[0002] The production process of continuously casting high-temperature molten steel into billets with a certain cross-sectional shape and size is called continuous steel casting. The equipment required to complete this process is called continuous casting equipment. The electromechanical-hydraulic integration of steel casting equipment, continuous casting machine body equipment, cutting area equipment, and dummy bar collection and conveying equipment constitutes the core equipment of continuous steel casting, which is conventionally called continuous casting machine. Its arc detection is an important and indispensable link, which is achieved by arc detection and adjustment of the sector segment.

[0003] For example, a device platform for a continuous casting machine sector arc detection and correction device, patent number CN201920287572.0, is provided. The sector detection platform and the movable straightedge support mechanism are both mounted on the device platform. The device platform is square, and several transverse and longitudinal grooves are evenly distributed on its upper surface. The transverse and longitudinal grooves divide the upper surface of the device platform into several square areas, which are used for positioning the sector detection platform and the movable straightedge support mechanism.

[0004] Since the arc measurement of the billet produced by the continuous casting machine is carried out in a fixed height state, it involves the adjustment of the large arc measurement of the billet continuous casting machine, which requires continuous adjustment of the plan and continuous demonstration. Changing the position of the measuring device is inconvenient and has brought certain adverse effects to actual use. Therefore, it needs to be improved. Utility Model Content

Based on the measurement results, the adjustment scheme generated is used to adjust the height of the base, forming the latest curvature data. The base data is then fine-tuned again based on the review results to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for measuring the curvature of a continuous casting machine includes a curvature measuring frame. A height adjustment seat is fixedly connected to the bottom of the curvature measuring frame. A drive motor is fixedly mounted on the right side of the curvature measuring frame via a fixed frame. A threaded support rod is fixedly connected to the output end of the drive motor. A threaded sleeve is threadedly connected to the surface of the threaded support rod.

A drive motor is fixedly mounted on the front side of the front push plate near its middle. A swing rod is fixedly connected to the output end of the drive motor. A positioning spotlight is fixedly mounted on the front side of the swing rod. The rear side of the positioning spotlight is slidably connected to the front side of the front push plate. A 3D laser tracker body is fixedly mounted on the bottom of the front push plate.

[0008] Furthermore, an electric cylinder two is fixedly installed on the inner wall of the height adjustment seat, and a lower support plate is fixedly connected to the output end of the electric cylinder two.

[0009] Furthermore, the locking assembly includes a magnetic locking upper slot and a magnetic locking lower plate.

[0015] 1. In this utility model, a 3D laser tracker body is set at the bottom of the front push plate in the arc measurement frame. The 3D laser tracker can measure the actual arc of the slab continuous casting machine and establish a 3D model to provide support for the adjustment scheme. Positioning spotlight one and positioning spotlight two are used for coordinated comparison. Positioning spotlight one is a fixed point on the front push plate, while positioning spotlight two is movable. That is, the operation of the drive motor two drives the swing rod to perform circumferential motion, which can change and adjust in real time to track and position the arc change of the casting slab, so that the 3D laser tracker can quickly position and measure, and roughly track and measure the arc. The operation of the drive motor one drives the threaded support rod to rotate.

The electric cylinder can drive the lower support plate to adjust its height. The magnetic locking upper groove and magnetic locking lower plate on the lower support plate are magnetically aligned, which can clamp and constrain the extension plate on the lower support plate, and connect and install the extension plates of different sizes and thicknesses. Under the action of the magnetic positioning plate, the magnetic positioning effect of the arc measuring frame can be enhanced. Based on the analysis of the previous measurement results, the position may be changed for measurement. The height of the height adjustment seat can be adjusted using the previously generated adjustment scheme to form the latest arc data. This can realize the practical tracking effect of measuring and aligning the arc of the continuous casting machine and correcting and re-measuring. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0026] A device for measuring the arc of a continuous casting machine includes an arc measuring frame 1. A height adjustment seat 2 is fixedly connected to the bottom of the arc measuring frame 1. A drive motor 3 is fixedly installed on the right side of the arc measuring frame 1 via a fixed frame. A threaded support rod 4 is fixedly connected to the output end of the drive motor 3. A threaded sleeve 5 is threadedly connected to the surface of the threaded support rod 4. A limit assembly is connected to the top of the threaded sleeve 5. An electric cylinder 6 is fixedly installed on the front side of the threaded sleeve 5. A front push plate 7 is fixedly connected to the output end of the electric cylinder 6. A positioning spotlight 8 is fixedly installed on the front side of the front push plate 7 near its top. A drive motor 9 is fixedly installed on the front side of the front push plate 7 near its middle. A swing rod 10 is fixedly connected to the output end of the drive motor 9. A positioning spotlight 11 is fixedly installed on the front side of the swing rod 10. The rear side of the positioning spotlight 11 is slidably connected to the front side of the front push plate 7. A 3D laser tracker body 12 is fixedly installed at the bottom of the front push plate 7.

[0027] Specifically, such as Figures 1-5As shown, an electric cylinder 13 is fixedly installed on the inner wall of the height adjustment seat 2. The output end of the electric cylinder 13 is fixedly connected to a lower support plate 14. A locking component is connected to the bottom of the lower support plate 14. An extension guard plate 15 is connected to the surface of the locking component. A magnetic positioning plate 16 is fixedly connected to the lower surface of the extension guard plate 15. The locking assembly includes a magnetic locking upper slot 17 and a magnetic locking lower plate 18. The magnetic locking upper slot 17 is located on the bottom of the lower support plate 14, and the magnetic locking lower plate 18 is fixedly connected to the top of the extension guard plate 15. The surface of the magnetic locking lower plate 18 and the inner wall of the magnetic locking upper slot 17 are magnetically engaged and adapted to each other. The height adjustment seat 2 at the bottom of the arc measuring frame 1 is abutted at a suitable measurement position. The electric cylinder 13 can drive the lower support plate 14 to adjust its height. The magnetic locking upper slot 17 and the magnetic locking lower plate 18 on the lower support plate 14 are magnetically aligned, which can complete the clamping constraint of the extension guard plate 15 on the lower support plate 14 and connect and install the extension guard plates 15 of different sizes and thicknesses. Under the action of the magnetic positioning plate 16, the magnetic positioning effect of the arc measuring frame 1 can be enhanced.

[0028] Specifically, such as Figures 1-5 As shown, the limiting assembly includes a limiting plate 19 and a limiting groove 20. The limiting plate 19 is fixedly connected to the top of the threaded sleeve 5, and the limiting groove 20 is opened on the top of the inner wall of the arc measuring frame 1. The inner wall of the limiting groove 20 and the surface of the limiting plate 19 are slidably connected. By setting the limiting plate 19 and the limiting groove 20, the movement trajectory of the threaded sleeve 5 is limited, so that the rotation of the threaded support rod 4 can drive the threaded sleeve 5 to move.

[0029] Please refer to Example 2 Figures 1-5 The difference between this embodiment and Embodiment 1 is that a side plate 21 is fixedly connected to the side of the front push plate 7, and an electric push rod 22 is fixedly installed on the rear side of the side plate 21. A magnetic abutment plate 23 is fixedly connected to the output end of the electric push rod 22. The operation of the electric push rod 22 on the side plate 21 can drive the magnetic abutment plate 23 to move, which can enhance the locking effect after the front push plate 7 is positioned to prevent movement. There are at least four magnetic abutment plates 23, and the at least four magnetic abutment plates 23 are evenly distributed around the circumference of the front push plate 7. The presence of at least four magnetic abutment plates 23 results in a stronger adhesion effect.

[0030] Furthermore, the main body of the arc measurement frame 1 is a rectangular frame with a front opening. The front side of the rectangular frame is rotatably connected to a protective baffle 24 via a drive end. Under normal conditions, the front protective baffle 24 of the arc measurement frame 1 can be closed for protection.

[0031] The working principle of this utility model is as follows: When in use, the arc measurement frame 1 is applied to the continuous casting machine. It can track and measure the arc measurement structure within the measuring device according to the billet size and process changes of the continuous casting machine. The height adjustment seat 2 below the arc measurement frame 1 is positioned at a suitable measurement location. The electric cylinder 13 drives the lower support plate 14 to adjust its height. The magnetic locking upper groove 17 and magnetic locking lower plate 18 on the lower support plate 14 are magnetically aligned, completing the clamping constraint of the extension guard plate 15 on the lower support plate 14. This facilitates the connection and installation of the extension guard plates 15 of varying sizes and thicknesses. The magnetic positioning plate 16 enhances the magnetic positioning effect of the arc measurement frame 1. Furthermore, because the bottom of the front push plate 7 is equipped with a 3D laser tracker body 12, the actual arc of the slab continuous casting machine can be measured using the 3D laser tracker, and a 3D model can be established, providing support for the adjustment scheme. The positioning spotlights 8 and 11 also provide coordinated comparison and positioning. Positioning spotlight 8 is a fixed point on the front push plate 7, while positioning spotlight 11 is movable. This allows the driving motor 29 to drive the swing rod 10 in a circular motion, enabling real-time adjustment and tracking of the billet's curvature changes. This facilitates rapid positioning and measurement by the 3D laser tracker, roughly tracking the curvature. The driving motor 3 can rotate the threaded support rod 4. The limiting plate 19 and limiting groove 20 limit the movement trajectory of the threaded sleeve 5, allowing the threaded support rod 4 to rotate and move the threaded sleeve 5, altering the curvature measurement effect below. The electric cylinder 6 can change the forward and backward direction of the front push plate 7, thus completing the tracking measurement of the billet's curvature. Based on the measurement results, the position can be changed for measurement. The height of the height adjustment seat 2 can be adjusted using the previously generated adjustment scheme to generate the latest curvature data. This achieves a practical tracking effect for measuring, aligning, correcting, and re-measuring the curvature of the continuous casting machine.
