Horizontally-push double-face braking speed reducer execution mechanism

The utility model provides a horizontally-push double-face braking speed reducer execution mechanism. On the basis of an existing internal supporting type braking mechanism, external push braking rails are additionally arranged outside basic rails, dual-direction movement of the internal-external execution mechanism is achieved, a train can be braked, a braking oil cylinder of the internal braking rail and a braking oil cylinder of the external braking rail are independent and do not interfere with each other, and dual guarantees and reliability of braking are improved. The execution mechanism is reliable in alignment, and wheels cannot be scratched when the train passes through the execution mechanism. An execution piece moves in a sliding friction mode, the resistance is low, and braking and remitting time is short. The structure of combining a supporting beam and a telescopic arm is adopted by the breaking speed reducer execution mechanism, the axial stress deformation is eliminated, the action is flexible, the mechanical strength is high, the safety factor is large, remission is thorough, collisions and interference can be avoided when a shunting operation is carried out on the train, mounting is easy, maintenance is convenient, a braking speed reduction device is directly clamped on the basic rails, mounting is convenient and fast, only a station track needs to be blocked in the mounting process, the operating of an adjacent line is not interfered, and the maintenance is easy and convenient.
