Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum liquid level height measurement, in particular to an aluminum liquid level height measurement device based on dual lasers. Background Art

[0002] In the casting process, it is usually necessary to accurately measure and control the height of the molten aluminum liquid in the launder of the melting and casting equipment to improve the stability and safety of the casting, thereby ensuring the quality of the cast product. Generally, this purpose is achieved by a laser ranging device. In this case, the laser ranging device needs to be of reliable quality and stable performance. According to the patent document with the authorization announcement number: CN221594032U, entitled "A device for measuring the height of molten aluminum liquid", an auxiliary mechanism is designed. The motor can drive the screw to rotate through the drive assembly, so that the screw drives the sliding seat to move back and forth on the slide rail through the thread. The sliding seat can drive the swing rod to move synchronously, so that the sliding rod slides back and forth in the slide groove on the fixed plate, thereby realizing the reciprocating movement of the laser ranging probe at the bottom of the seat along the guide ring. During the movement of the laser ranging probe, the liquid level inside the melting and casting equipment can be measured at multiple points. The liquid levels at multiple liquid levels are comprehensively analyzed, making the measurement results of the molten aluminum liquid level more accurate and reducing the impact of the fluctuation of the aluminum liquid level on the measurement results. However, the following defects still exist:

[0003] Its sliding rod slides back and forth in the semicircular groove on the fixed plate, driving the two laser ranging probes to move in an arc to measure the liquid level of the aluminum liquid. However, the semicircular groove is set near the edge of the fixed plate, which makes it difficult for the laser ranging probes to move to a position close to the center of the fixed plate, making it inconvenient to measure the liquid level at any position of the aluminum liquid.
