Title:
STEEL RAIL TEMPERATURE AND INTERNAL STRESS MONITORING APPARATUS FOR STRESS RELIEF OPERATIONS
Document Type and Number:
WIPO Patent Application WO/2023/216905
Kind Code:
A1
Abstract:
A steel rail temperature and internal stress monitoring apparatus for stress relief operations, comprising a steel rail, a measuring apparatus, a data transmission apparatus, and a master control module, the network topology structure between the data transmission apparatus and the master control module being a bus-type connection, the measuring apparatus being connected to the steel rail and being used for measuring data of the steel rail, the measuring apparatus being composed of a temperature strain gauge (1-1), an internal stress strain gauge (1-2), a reinforcing apparatus (1-4), and an adsorption apparatus (1-3), and the equipment using sensors to measure the steel rail temperature and internal stress, effectively reducing the amount of operations in the measurement process and increasing the measurement efficiency.
