Description

[Technical Field]

[0001] This utility model relates to the technical field of tunnel boring machine belt conveyor systems, and in particular to a novel belt conveyor speed detection device. [Background Technology]

[0002] Belt conveyor speed detection devices are mechanical equipment primarily used in tunnel boring machine belt systems. Currently, belt conveyors play a crucial role as connecting and transporting equipment between various processes. With increasing production capacity, high-speed, heavy-duty belt conveyors are now widely adopted. Modern production lines are almost entirely continuous and automated, placing higher demands on the stable operation of mechanical equipment. However, uneven material feeding is unavoidable in actual production, often causing belt slippage, resulting in low-speed or stopped operation. This leads to material accumulation and spillage, requiring manual cleaning, increasing worker workload and impacting the production environment. Furthermore, even when belt slippage causes low-speed or stopped operation, the drive motor at the conveyor head continues to run at the set speed. Prolonged friction can easily cause belt tearing, severely affecting continuous production and causing significant economic losses. Therefore, real-time and accurate measurement of belt speed is crucial to understanding the belt's operating status and preventing economic losses.

[0003] Most existing belt speed detection devices for conveyors have complex structures, are inconvenient to maintain, and have high maintenance costs, so improvements are needed. [Utility Model Content]
