Technical Field

[0001] The utility model relates to the technical field of thermocouples, in particular to a thermocouple telescopic device for a reforming furnace. Background Technique

[0002] A thermocouple is a commonly used temperature measuring element in a temperature measuring instrument. It directly measures the temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). Therefore, a thermocouple is usually used to measure the temperature in the furnace chamber of a reforming furnace in real time.

[0003] In this regard, Chinese Patent Application No.: CN215726429U discloses a thermocouple telescopic device for a heating furnace. The telescopic device includes a support mechanism fixed to the outer side wall of the heating furnace. A horizontal sliding mechanism is provided on the support mechanism. An assembly mechanism for fixing the thermocouple is slidably provided on the horizontal sliding mechanism. A fastening and buffering mechanism for extending and fastening the thermocouple is further provided on the assembly mechanism. The horizontal sliding mechanism of the telescopic device enables the detection end of the thermocouple to extend and retract in the heating furnace, facilitating the discharging operation of the workpiece in the heating furnace, avoiding damage to the detection end of the thermocouple when the workpiece is discharged, and effectively ensuring the use safety of the thermocouple. The function of the fastening and buffering mechanism is to fix the state after the thermocouple extends into the heating furnace, avoiding the problem that the thermocouple exits the heating furnace due to the sliding action of the horizontal sliding mechanism and affecting the temperature measurement.

[0004] However, in actual use, the stability of the thermocouple during installation is poor, and subsequent disassembly is also relatively troublesome. Moreover, the prior art can only extend and retract the thermocouple and cannot measure the actual size of the extension and retraction. Therefore, improving and modifying the above problems has become an urgent problem to be solved at present. Summary of the Utility Model
