Track expansion compensation device used in high-temperature furnace

A track expansion compensation device used in a high-temperature furnace relates to the field of expansion compensators and comprises an expansion frame structure and an expansion track structure arranged on the expansion frame structure, the expansion frame structure comprises a plurality of fixed outer plates, limiting sleeves arranged on the fixed outer plates in a penetrating mode and supporting plates arranged on the fixed outer plates, and the limiting sleeves are arranged on the fixed outer plates in a penetrating mode. The telescopic track structure is arranged on the supporting plate, and the frame expanding structure can move along the limiting sleeve to drive the telescopic track structure to stretch out and draw back. According to the utility model, the problem that the workpiece is stuck in the furnace due to the deformation of the track is effectively solved, manual maintenance in the furnace is avoided when the workpiece is stuck in the furnace, and the production efficiency is greatly improved
