Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology, and more specifically, to a measuring drive mechanism. Background Technology

[0002] In existing steel rolling production lines, the control of the pusher in pusher-type heating furnaces is achieved through a hydraulically driven transmission mechanism that pushes the steel billet for feeding. Real-time monitoring of the equipment's operating position is necessary for automatic control throughout the process. Currently, most steel rolling production lines in China using pusher-type heating furnaces have manually controlled pushers, which disrupts production rhythm and increases manufacturing costs. Some production lines employ a technique of installing embedded displacement sensors within hydraulic cylinders to measure the actual operating position of the pusher and address the data feedback issues required for automatic control.

[0003] In the existing technology, the hydraulic cylinder of the steel pusher is large in size. When the displacement sensor is damaged and needs to be replaced, the hydraulic cylinder must be disassembled for replacement. The replacement requires a large working radius and takes a long time, which affects the normal operation of the production line. Utility Model Content
