High frequency fatigue/dynamic load tester for clips for railway rail fasteners

摘要

PROBLEM TO BE SOLVED: To provide a high frequency fatigue/dynamic load tester for a clip for a rail rail fastener, which can perform a dynamic fatigue simulation at a high frequency according to a response frequency that the clip receives in actual use. To do. SOLUTION: A frame (1), a motor (2), a transmission shaft mechanism (3), a load rod mechanism (4), a load block (5), a clip holder mechanism (6), a protective enclosure (7) and a rack. It has a base surface (8), the small pulley (21) and the large pulley (33) are transmission-coupled by a toothed belt, and the large pulley (33) and the cam (34) are attached to the cam shaft (31). The load rod mechanism (4) has one end abutted against the cam (34) and the other end connected to the load block (5), and the load block (5) is the clip holder. It comes into contact with a clip specimen (62) mounted on the mechanism (6). [Selection diagram] Figure 1
