The invention discloses an interlocking assembly and a locomotive key-lifting switch. The interlocking assembly comprises a mounting plate, a poking piece is arranged above the mounting plate, a limiting hole is formed in the poking piece, a button rod used for limiting movement of the poking piece is arranged in the limiting hole, the button rod penetrates through the mounting plate, and the bottom of the button rod is connected with the mounting plate through a limiting mechanism. A pull key and a lock head assembly are arranged on the mounting plate, a clamping groove matched with the pullkey is formed in the poking piece, a guide column is further arranged on the poking piece, a driving piece used for driving the guide column to move is arranged on the lock head assembly, and a groovematched with the guide column is formed in the mounting plate. The gears can be switched only by pressing the button rod, so that sudden power failure of equipment due to the fact that the lock handle is pulled back from the closing position to the opening position after mis-operation of a driver is avoided; the installation is simple, and a special tool is not needed; the structure is reliable,the needed installation space is small, and the maintenance is convenient.
Description
technical field [0001] The invention belongs to the technical field of locomotive switches, relates to an interlocking assembly, and also relates to a locomotive toggle switch using the interlocking assembly. Background technique [0002] At present, before the railway locomotive usually starts to run, the lock switch on the used toggle switch needs to be pulled to the close position, and then the small toggle switches are opened in sequence, and then the locomotive equipment is powered on for operation. During the operation of the locomotive, since there is no interlock, the handle of the lock switch can be pulled back from the close position to the separate position. There are hidden dangers like this, and the driver has the possibility of misoperation, and the lock switch handle is pulled to the position, resulting in a sudden power failure of the high-voltage equipment, which is very prone to safety accidents. Contents of the invention [0003] The purpose of the pres...
