Buried electro-hydraulic switch machine

Abstract

The invention discloses a buried electro-hydraulic point switch, and belongs to the technical field of railway traffic equipment. In order to solve the problems of complex structure, reduced reliability of the whole equipment and low efficiency of a buried electro-hydraulic switch machine in the prior art, the invention provides a buried electro-hydraulic switch machine. The buried electro-hydraulic switch machine comprises a switch machine shell, an EHA electro-hydraulic execution system, an actuating rod mechanism, an indication rod mechanism, a node seat system and a manual operation system, wherein the EHA electro-hydraulic execution system is fixed on a corresponding mounting seat of the switch machine shell, the actuating rod mechanism is inserted into a corresponding through hole ofthe switch machine shell, the actuating rod mechanism comprises a starting mechanism, the starting mechanism is clamped on the EHA electro-hydraulic execution system, the indication rod mechanism ismounted at a corresponding mounting position of the switch machine shell, the node seat system is fixed to the switch machine shell mounting seat, and the manual operation system is connected with theactuating rod mechanism. The buried electro-hydraulic switch machine is simple in structural design, easy to operate, higher in operation efficiency of the whole equipment and more convenient to usein road traffic.

Description

technical field [0001] The invention belongs to the technical field of railway traffic equipment, in particular to an underground electro-hydraulic switch machine. 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 pedestrians and other vehicles. Therefore, the starting point of the design of...
