Description

Technical Field

[0001] This application relates to the field of rail transit control device technology, and more specifically, to a handle device for a locomotive driver controller. Background Technology

[0002] The driver controller is used in high-speed trains, railway electric locomotives, and diesel locomotives. It serves as the master electrical control for traction, braking, and direction control, adjusting traction conditions, changing direction, setting speed, and controlling starting and speed regulation. The driver controller is directly mounted on the driver's console, with its main body located below the console panel and concealed within it. Its human-machine interface, the handle, protrudes above the console panel.

[0003] Currently, when operating a Harmony locomotive, the driver needs to press the button head to move the button lever, and then mechanically unlock it through the interlocking pin before pushing the operating handle to control the locomotive.

[0004] Mechanical unlocking is achieved by pressing the middle button on the driver's controller lever, which in turn moves the lower interlocking pin. The interlocking pin is located in the middle of the lever. If other handle device fixing parts that use open retaining rings or similar structures to fix the interlocking pin fall off, the interlocking pin will move left and right, causing it to jam. This will cause the button lever to jam, preventing the driver's controller from operating normally and posing a significant safety hazard to the safe operation of the locomotive.

[0008] In one possible implementation, the boss structure of the interlocking pin is located in its middle, and the diameter of the boss is larger than the diameter of the interlocking pin body, which is used to limit the axial displacement of the interlocking pin.

[0009] In a possible implementation, the handle rod is fixed to the handle seat, the handle head is fixed to the end of the handle rod, and the reset spring is arranged between the handle head and the handle rod.

[0010] In a possible implementation, the button head is circular, the diameter of the button head is greater than the diameter of the button rod, and the surface of the button head is provided with an anti-skid pattern.

[0013] In a possible implementation, the reset spring is a spiral spring, and the two ends of the reset spring are respectively clamped in grooves of the handle head and the handle rod.

[0014] In a possible implementation, the curing strength of the high-strength thread glue is not less than 10 MPa, and the temperature resistance range is -54 DEG C to 180 DEG C.
