The program of the PLC system 23 of the device is adjusted and perfected according to the actual field.
When the first traction chain 14 or the second traction chain 19 in the swing rod 12 is broken or power is cut off due to external reasons, the first lifting motor 11 or the second lifting motor 18 cannot drive the temperature measuring probe 15 or the sampling probe 20 to ascend, and the temperature measuring gun is burnt out due to the fact that the temperature measuring gun is soaked in molten steel for too long time. An operator immediately goes to a third horizontal working platform of the support frame 6 to manually open a corresponding motor brake, manually and clockwise shakes a handle on the fixed pulley 9, and the traction rope 10 drives a corresponding temperature measuring probe 15 or a corresponding sampling probe 20 to slowly rise under the auxiliary traction action of the respective steel wire rope counterweight block 8 until the temperature measuring probe 15 or the sampling probe 20 leaves the molten steel liquid level and returns to a safe position.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
