Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0019] The new energy storage pneumatic and electro-hydraulic power point machine is characterized in that it includes a casing 1, an extruding node group 7 arranged in the casing 1, a terminal group 10, a rubber hose arranged on the upper part of the casing 1, and a rubber hose arranged on the side of the casing 1. The protection tube 2 connected to the extruded node group 7, the indicating rod 3 arranged at the other end of the shell 1 connected to the extruded node group 7, and the conversion locker, the conversion locker includes a start conversion locker and an electric conversion locker. It is driven by an AC motor 14 and is equipped with accumulators, hydraulic reversing valves, pressure relays, locks and other components. Under normal circumstances, the elastic lock is implemented on the close-fitting tongue rail by hydraulic pressure. When the pressure is lo...

Description
technical field [0001] The invention relates to a switch machine, in particular to a pneumatic and electro-hydraulic switch machine. Background technique [0002] The electro-hydraulic switch machine is a special equipment for centralized control of switching switches in railways, underground railways, and urban rail transit stations. It can convert and lock the point rail or center rail of the switch, and at the same time give the position indication of the corresponding point rail. With the development of railway transportation in the direction of heavy load and high speed, the reliability requirements for switch machines are getting higher and higher. The existing domestic turnout switching equipment mainly includes electric and electro-hydraulic switch machines. Among them, the electric switch machine mainly has unstable switching force output, difficult adjustment, large mechanical wear, many control materials, investment and energy consumption. However, the existing ...
