Abstract

The invention discloses an electric switch machine, which belongs to the technical field of switch machines and comprises an indication rod, an action rod and a power assembly, a locking mechanism is arranged on the action rod, a contact assembly is arranged on the indication rod, and the power assembly comprises a shifting plate, a motor for driving the shifting plate to move and a transmission system; the locking mechanism comprises a locking body and a lock hook; an inserting hole is horizontally formed in the locking body in the movement direction of the action rod, a through hole is formed in the locking body, the inserting hole and the through hole are communicated through a communicating hole, a locking roller is arranged in the communicating hole, a check block is arranged in the locking body and located above the locking roller, and a groove matched with the locking roller is formed in the front end of the lock hook. Effective and reliable locking action of the action rod is guaranteed, the extrusion cutting pin is protected, and the phenomenon of abnormal breakage is avoided; the transmission stability and precision are guaranteed, the structure is compact, and the more stringent limit requirement can be met; and the conversion efficiency and stability of movable and static contacts are improved.

Description

technical field [0001] The invention belongs to the technical field of switch machines, in particular to an electric switch machine. Background technique [0002] The switch machine refers to the important signal infrastructure equipment used to reliably change the position of the turnout, change the opening direction of the turnout, lock the tip rail of the turnout, and reflect the position of the turnout. It can well ensure driving safety, improve transportation efficiency, and improve the safety of driving personnel labor intensity. [0003] The locking mechanism provided on the action lever in the switch machine is used to ensure that the position of the action lever is locked when it moves to both ends, but the existing locking mechanism cannot guarantee that the action lever is locked at both ends. Effective and reliable closing; the existing locking mechanism and the action rod are provided with a squeeze pin to protect the switch machine from being damaged when the ...
