DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] As Figures 1 to 3As shown, an aluminum liquid level control device for continuous casting and rolling of aluminum plate includes an iron box 1, a heat-resistant box 2, a fixed plate 3, a telescopic cylinder 4, an extension shaft 5, a connecting rod 6, an elastic assembly 7, and a plug 8. The heat-resistant box 2 is fixedly arranged in the iron box 1. The fixed plate 3 is fixedly connected with the iron box 1. The telescopic cylinder 4 is fixedly connected with the fixed plate 3. The extension shaft 5 is fixedly connected with the output end of the telescopic cylinder 4 in a horizontal state. One end of the elastic assembly 7 is connected with the extension shaft 5. The other end of the elastic assembly 7 is connected with the connecting rod 6. The iron box 1 and the heat-resistant box 2 are provided with a liquid discharge hole 9 communicating with each other at the side portions. One end of the plug 8 is connected with the connecting rod 6 in a matching mode. The other end of the plug 8 is arranged in the liquid discharge hole 9 in a matching mode. The elastic assembly 7 includes an elastic joint 10 and an elastic horn 11. The elastic joint 10 is fixedly connected with the extension shaft 5. The elastic horn 11 is fixedly connected with the connecting rod 6. The elastic joint 10 and the elastic horn 11 are rotatably connected in a matching mode.

[0023] When the telescopic amount of the telescopic cylinder 4 exceeds the normal range, the elastic horn 11 is pressed in the elastic joint 10 and rotates. This rotation limits the further movement of the plug 8, thereby avoiding position overshoot and protecting the equipment from damage.

[0024] Once the telescopic amount of the telescopic cylinder 4 returns to normal, the elastic horn 11 automatically returns to the initial state due to the restoring force of the elastic joint 10, drives the plug 8 to return to the predetermined position, realizes automatic reset, and ensures the continuous and accurate control of the aluminum liquid flow.

[0025] By adjusting the position relationship between the extension shaft 5, the connecting rod 6, the elastic assembly 7, and the plug 8, the device can adjust the position of the plug 8 in multiple directions according to the actual production needs, significantly improving the flexibility and accuracy of the aluminum liquid flow control. The elastic deformation of the elastic assembly 7 realizes the overshoot protection and automatic reset of the plug 8.

[0026] Reference Figure 3 As shown, in some specific embodiments, the connecting rod 6 is a threaded rod, and the elastic horn 11 is provided with a threaded hole 12 threadedly connected with the connecting rod 6. The position relationship between the connecting rod 6 and the elastic horn 11 is adjusted by rotation, and then the fine adjustment of the position of the plug 8 is realized. The accuracy of the position adjustment of the plug 8 is ensured, the aluminum liquid flow fluctuation caused by improper adjustment is reduced, and the continuous casting and rolling quality is improved.

[0027] Reference Figure 3 As shown, in some specific embodiments, the connecting rod 6 is a threaded rod, and the plug 8 is provided with a matching hole 13 threadedly connected with the connecting rod 6. The fine adjustment of the position of the plug 8 is directly realized by rotating the plug 8. The accuracy of the position adjustment of the plug 8 is ensured, the aluminum liquid flow fluctuation caused by improper adjustment is reduced, and the continuous casting and rolling quality is improved.

[0028] ReferenceFigure 1 As shown, in some embodiments, the fixed plate 3 is provided with a liquid level monitoring assembly 14. The liquid level monitoring assembly 14 includes a liquid level detection sensor 15 and a sensor bracket 16 fixedly arranged on the fixed plate 3 for fixing and supporting the liquid level detection sensor 15; the liquid level detection sensor 15 is fixedly connected with the sensor bracket 16 and is responsible for real-time monitoring of the liquid level of aluminum liquid. The sensor bracket 16 includes a lifting rod 17 and an adjusting rod 18, the lifting rod 17 is connected with the fixed plate 3 in a vertical state, the adjusting rod 18 is connected with the lifting rod 17 in a horizontal state, and the liquid level detection sensor 15 is fixedly connected with the adjusting rod 18. The fixed plate 3 is provided with a first positioning clamp 19, the lifting rod 17 is arranged in the first positioning clamp 19, the first positioning clamp 19 is used for fixing the lifting rod 17, the top of the lifting rod 17 is provided with a second positioning clamp 20, the adjusting rod 18 is arranged in the second positioning clamp 20, and the second positioning clamp 20 is used for fixing the adjusting rod 18.

[0029] Through the lifting rod 17, the adjusting rod 18, the first positioning clamp 19 and the second positioning clamp 20, it is ensured that the liquid level detection sensor 15 can accurately and stably monitor the liquid level of aluminum liquid, and the monitoring accuracy is improved. The adjustability of the liquid level monitoring assembly 14 enables the device to easily adapt to aluminum plate continuous casting and rolling machines of different specifications and sizes, as well as liquid level monitoring requirements under different production conditions.

[0030] Reference Figure 1 As shown, in some embodiments, the telescopic cylinder 4 is a servo electric cylinder. The servo electric cylinder combines the precise control of the servo motor and the linear motion characteristics of the electric cylinder. This combination enables the servo electric cylinder to provide strong thrust while maintaining high position accuracy and speed control.

[0031] Reference Figure 2 As shown, in some embodiments, the plug 8 is made of graphite material. At high temperatures, the volume change of graphite is not obvious, and the thermal expansion coefficient is small, so it can maintain stable physical properties.

[0032] In order to facilitate the understanding of the working principle of the embodiments of the present scheme by the personnel in the art, the working principle of the embodiments of the present scheme will be described in combination with specific application scenarios:

[0033] When the telescopic amount of the telescopic cylinder 4 exceeds the normal range, the elastic horn plate 11 is squeezed inside the elastic joint 10 and rotates, which limits the further movement of the plug 8, thereby avoiding position overshoot and protecting the equipment from damage.

[0034] Once the telescopic amount of the telescopic cylinder 4 returns to normal, the elastic horn plate 11 automatically returns to the initial state due to the restoring force of the elastic joint 10, driving the plug 8 to return to the predetermined position, realizing automatic reset and ensuring the continuous and accurate control of the flow of aluminum liquid.

[0035] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims shall be construed as limiting the scope of the claims.
