Temperature measuring rod device for steelmaking continuous casting ladle

The utility model relates to the technical field of cast steel, and discloses a steelmaking continuous casting ladle temperature measuring rod device which comprises an elevator body, a steel rod is connected to the lower end of the elevator body, a temperature measuring rod is arranged on the outer wall of the steel rod in a sleeved mode, a connecting block is connected to the upper end of the steel rod, a sliding groove is formed in the lower end of the connecting block, and a limiting assembly is connected into the sliding groove in a sliding mode. The outer wall of the connecting block is slidably connected with a sleeve. According to the steelmaking continuous casting ladle temperature measuring rod device, after a temperature measuring rod is lifted from a middle ladle, a limiting assembly is pushed back into a sliding groove in the lower end of a connecting block, so that a sleeve slides downwards from the outer wall of the connecting block, and when the sleeve slides till the inner wall of the sleeve
