The invention provides an underground electro-hydraulic switch machine actuating rod mechanism and a working method thereof. The underground electro-hydraulic switch machine actuating rod mechanism is inserted into a corresponding through hole of a switch machine shell (1) and comprises a starting mechanism (35), the starting mechanism (35) is clamped to an EHA electro-hydraulic execution system (2), the actuating rod mechanism (3) further comprises an actuating rod (31), an actuating rod sleeve (32), a squeezing-off mechanism (33), a locking block (34) and a quick-acting piece (36), a first groove (37) is formed in the quick-acting piece (36), and a first groove (37) is formed in the quick-acting piece (36). The actuating rod (31) penetrates through the actuating rod sleeve (32) and is fixed by a squeezing mechanism (33), the locking block (34) is fixed on the actuating rod sleeve (32), and the quick-acting piece (36) is fixed on the starting mechanism (35) through a pin shaft. The power of the EHA electro-hydraulic actuating system is hydraulically driven, the connecting structure is simple, the reliability is high, the maintenance workload is small, a locking area is visible through visual inspection, and the EHA electro-hydraulic actuating system is more convenient to use for road traffic.
Description
technical field [0001] The invention belongs to the technical field of railway traffic equipment, and in particular relates to an operating lever mechanism of an underground electro-hydraulic switch machine and a working method thereof. Background technique [0002] The national conditions of my country's large population determine the long-term implementation of the strategy of "prioritizing the development of public transportation". Urban rail transit has gradually become the focus of public transportation development in tourist cities and urban agglomerations. In recent years, due to the stable development of the economy and the strong support of the government, the construction of urban rail transit in my country has gradually expanded, and it has become the largest market for urban rail transit construction in the world. In the tram project, urban rail transit transportation line facilities are on urban roads, and it is inevitable to cross and share the road with pedest...
