Technical Field

[0001] The utility model relates to the technical field of mechanical measurement, in particular to a measuring device for a truncated cone scroll spring of a pyrometallurgical furnace. Background Art

[0002] As a special type of spring, truncated conical scroll springs are widely used in transmission, sealing, and shock-absorbing devices within furnaces. Their contraction and expansion accurately reflect the furnace's production status. Therefore, during the maintenance and production of pyrometallurgical furnaces, accurate measurement of truncated conical scroll springs is crucial for assessing the furnace's operating status, preventing potential failures, and performing necessary repairs and adjustments. Due to the confined space and large number of truncated conical scroll springs, manual measurement is currently the most common method. This requires the operator to crouch beneath the spring to read the spring, resulting in significant measurement errors and low efficiency. Furthermore, prolonged measurements near the furnace body pose serious safety risks. Utility Model Content
