Description

Technical Field

[0001] This application relates to the technical field of rail transit control devices, and more particularly, to a handle device for a Harmony locomotive driver controller. Background Art

[0002] Driver controllers are used in high-speed trains, railway electric locomotives, and diesel locomotives. As the main command electrical appliance for controlling the traction, braking, and direction control of locomotives and rolling stock, they are used to adjust the traction conditions of locomotives, change the running direction of locomotives, set the running speed of locomotives, and achieve the starting and speed regulation of locomotives. The driver controller is directly installed on the driver's console. Its main body is located below the console panel and hidden inside the console, and its human-machine operation interface, that is, the handle, is exposed above the console panel.

[0003] Currently, when a Harmony locomotive driver operates, the driver needs to press the button head to drive the button rod and mechanically unlock it through an interlocking pin before pushing the operating handle to perform locomotive control work.

[0004] Since mechanical unlocking is achieved by pressing the button head in the middle of the driver controller handle rod to drive the button rod to drive the lower interlocking pin, and the interlocking pin is located in the middle of the handle rod, if other fixing parts of the handle device that fix the interlocking pin with an open circlip or other structures fall off, the left and right movement of the interlocking pin will cause the interlocking pin to get stuck, resulting in the button rod getting stuck and causing the driver controller to malfunction, posing a great safety hazard to the safe operation of the locomotive.

[0008] In a possible implementation, the boss structure of the interlocking pin is located in the middle thereof, and the diameter of the boss is greater than the diameter of the main body of the interlocking pin, 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 base, the handle head is fixed to the end of the handle rod, and the return spring is disposed between the handle head and the handle rod.

[0013] In a possible implementation, the return spring is a helical spring, and its two ends are respectively clamped in the 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 tolerance range is -54 °C to 180 °C.

[0015] In a possible implementation, the thread length of the interlock pin is 10 - 15 mm, and the pitch is 0.8 mm.

[0022] In order to make the purpose, implementation manners and advantages of the present application clearer and more understandable, the following will clearly and completely describe the exemplary implementation manners of the present application in combination with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequent described implementation manners, rather than intending to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0024] The terms "first", "second", "third", etc. in the specification, claims and the above drawings of the present application are used to distinguish similar or same-kind objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that such terms can be interchanged under appropriate circumstances.

[0025] The terms "include" and "have" and any of their variations are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to all the clearly listed components, but may include other components that are not clearly listed or are inherent to these products or devices.

[0026] Before explaining the handle device for a Harmony locomotive driver controller provided in the embodiments of the present application, the application scenarios and implementation environments of the embodiments of the present application will be introduced first.

[0027] The driver controller is used in high-speed EMUs, railway electric locomotives and diesel locomotives. As the main command electrical appliance for controlling the traction, braking and direction control of locomotives and vehicles, it is used to adjust the traction working conditions of locomotives, change the running direction of locomotives, set the running speed of locomotives, and realize the starting and speed regulation and other working conditions of locomotives. The driver controller is directly installed on the driver's console, its main body is located below the console panel and hidden inside the console, and its human-machine operation interface, that is, the handle, is exposed above the console panel.

[0028] Currently, when a Harmony locomotive driver operates, the driver needs to press the button head to drive the button rod and mechanically unlock it through the interlocking pin before pushing the operation handle to perform locomotive control work.

[0029] Since mechanical unlocking is achieved by pressing the middle button head of the driver controller handle rod to drive the button rod and then drive the lower interlocking pin, the interlocking pin is in the middle position of the handle rod. When other fixing parts of the handle device that fix the interlocking pin with snap rings and other structures fall off, the left and right movement of the interlocking pin will cause the interlocking pin to get stuck, resulting in the button rod getting stuck and causing the driver controller to malfunction, which brings great potential safety hazards to the safe operation of the locomotive.

[0030] Based on this, the present application provides a handle device for the driver controller of a Harmony locomotive, including a circular button head fixed on the button rod, a cylindrical interlocking pin with a boss fixed on the button rod, a return spring fixed between the handle head and the handle rod, a handle rod fixed on the handle seat, and a handle head fixed on the handle rod. It is characterized in that: the button head and the interlocking pin are respectively fixed on the button rod, and an appropriate amount of high-strength thread glue is applied at the thread of the interlocking pin before installation. After tightening the interlocking pin, the interlocking pin and the button rod become an integral body through the high-strength thread glue, solving the problem of unreliability caused by the loosening of the interlocking pin.

[0031] Next, through examples and in combination with the drawings, the technical solutions of the present application will be specifically described in detail, as well as how the technical solutions of the present application solve the above technical problems. The examples can be combined with each other, and the same or similar concepts or processes may not be repeated in some examples. Obviously, the described examples are part of the examples of the present application, rather than all the examples.

[0032] Figure 1 It is a schematic diagram of the overall structure of a handle device for the driver controller of a Harmony locomotive shown in an exemplary embodiment of the present application.

[0033] In an exemplary embodiment, as Figure 1 shown, a handle device for the driver controller of a Harmony locomotive is provided. In this embodiment, the device may include a button rod, a circular button head fixed on the button rod, a cylindrical interlocking pin with a boss, a handle rod, a handle head, and a return spring; the interlocking pin is fixed on the button rod by threaded connection, and high-strength thread glue is applied at the threaded connection between the interlocking pin and the button rod to cure them into an integral body.

[0034] Among them, the curing strength of the high-strength thread glue is not less than 10 MPa, and the temperature tolerance range is -54°C to 180°C.

[0035] Figure 2 It is a schematic cross-sectional view of a handle device for the driver controller of a Harmony locomotive shown in an exemplary embodiment of the present application.

[0036] In a possible implementation, the boss structure of the interlock pin is located in the middle thereof, and the diameter of the boss is larger than the diameter of the interlock pin body, which is used to limit the axial displacement of the interlock pin. The material of the interlock pin is high-strength alloy steel, and its surface is treated with rust prevention. The thread length of the interlock pin is 10 - 15 mm, and the pitch is 0.8 mm.

[0037] The specific implementation is as Figure 2 shown. The interlock pin is a cylindrical structure with a boss, and the material is selected as high-strength alloy steel. The surface is treated by electroplating to improve the rust prevention performance. During installation, first evenly apply high-strength thread glue in the threaded hole of the button rod, and then screw the threaded end of the interlock pin into the button rod. The tightening torque is 5.3 N·m. After the thread glue cures, it forms a non-removable connection, completely avoiding the risk of detachment of traditional mechanical fasteners.

[0038] 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 return spring is arranged between the handle head and the handle rod. The handle rod and the handle seat are fixedly connected by bolts, and a sealing gasket is provided at the connection.

[0039] The specific implementation is as Figure 2 shown. The handle head is fixed to the end of the handle rod by bolts, and a return spring is arranged between them. The return spring is a helical spring, and its two ends are embedded in the annular grooves of the handle head and the handle rod. When the handle head is pushed by the operator, the return spring is compressed and deformed, and automatically rebounds to the initial position after being released, ensuring the sensitivity and stability of the operation. A rubber layer is coated on the surface of the handle head, and the thickness of the rubber layer is 2 - 3 mm, and the hardness is Shore A 60 - 70.

[0040] In a possible implementation, the button head is circular, its diameter is larger than the diameter of the button rod, and the surface of the button head is provided with anti-slip lines.

[0041] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
