[0023] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0024] As Figures 1-5 shown, the steel surface quality monitoring device of this embodiment includes a working table 1. A monitoring table 2 is provided in the middle of the working table 1. The monitoring table 2 is designed with a hollow structure to ensure that the upper and lower image acquisition devices can perform image acquisition operations. A support column 3 is installed on one side of the working table 1, and a positioning column 4 is provided on the other side. A cross beam 5 is provided between the support column 3 and the positioning column 4. A height adjustment mechanism for driving the cross beam 5 to move longitudinally is provided on the support column 3. Monitoring equipment is provided on the cross beam 5. A mounting seat 6 for installing the monitoring equipment is provided on the cross beam 5. The mounting seat 6 is slidably connected to the cross beam 5. By means of the adjustment mechanism, the cross beam is driven to perform longitudinal displacement, so as to change the distance between the image acquisition device and the steel. It can ensure that when image acquisition is performed on steel with different thicknesses, the distance between the two remains unchanged, always maintaining the best working distance, and there is no need to stop the operation. Compared with existing equipment, it can save a large amount of equipment replacement time and improve the operation efficiency.

[0025] The height adjustment mechanism includes a driving motor 7 located at the upper part of the support column 3. An adjusting screw 8 connected to the driving motor 7 is provided inside the support column 3. A connecting seat 9 that moves longitudinally along the adjusting screw 8 is provided on the adjusting screw 8. A placement groove is provided on one side of the support column 3, and the adjusting screw 8 is installed in the placement groove. One end of the connecting seat 9 is provided with a threaded sleeve sleeved outside the adjusting screw 8, and the other end is detachably connected to the cross beam 5.

[0026] The number of connecting seats 9 is two. The adjusting screw 8 is provided with a positive and negative thread for adjusting the distance between the two connecting seats 9. The design of the positive and negative thread can perform synchronous adjustment.
