Abstract
Description
Technical Field
[0001] This application relates to the field of rail transit control device technology, and more specifically, to a reversing handle with a ball-head plunger, a driver controller, and a control method thereof. Background Technology
[0002] The driver controller is a control device for railway locomotives, EMUs, and industrial automation. It is mainly used to control the locomotive's reversing and diesel engine / electric motor speed regulation, thereby controlling the locomotive's running direction, power, traction, and speed. The driver controller is directly installed on the driver's console, with its main body located below the console panel and hidden inside the console. Its human-machine interface, i.e., the handle, is exposed above the console panel.
[0003] Traditional driver controller reversing handles use a mechanical hexagonal structure, which results in complex structure, difficult processing, complex production process, high cost, poor interchangeability, and easy mechanical wear during use, leading to jamming. This results in insufficient reliability and maintainability, affecting the normal operation of the locomotive.
[0004] Therefore, there is an urgent need for a reversing handle structure that is simplified, reliable in positioning, easy to maintain, and adaptable to high-intensity vibration environments. Summary of the Invention
[0005] In view of this, in order to solve the above-mentioned problems in the prior art, this application provides a reversing handle with a ball-head plunger, a driver controller and a control method thereof.
[0006] The embodiments of this application are implemented as follows:
[0007] In a first aspect, this application provides a reversing handle with a ball plunger, including a small handle, a handle plate, a ball plunger, and a screw;
[0008] One end of the handle plate is provided with a mounting part, and the small handle is fixedly connected to the mounting part by the screw;
[0009] The other end of the handle plate is provided with a square opening for connecting to the reversing shaft, and the front end of the square opening is chamfered.
[0010] The side wall of the handle plate is formed with a circular positioning shoulder through a diameter expansion process;
[0011] The ball plunger is equipped with a spring and a steel ball inside, and the ball plunger is pressed and fixed to the circular positioning shoulder.
[0012] In one possible implementation, the handle plate has a flat cross-sectional shape.
[0013] In one possible implementation, the circular locating shoulder and the housing of the ball plunger are interference-fitted.
[0014] In one possible implementation, the circular positioning shoulder has a hole for accommodating the ball plunger, and the ball plunger is pressed into the hole to achieve fixation.
[0015] In one possible implementation, the mounting portion is a radially threaded hole provided on the handle plate, and the screw passes through the small handle and is screwed into the radially threaded hole.
[0016] In one possible implementation, a positioning pin is also provided between the small handle and the handle plate to prevent relative rotation.
[0017] In one possible implementation, the spring is a stainless steel compression spring.
[0018] In one possible implementation, the steel ball is a cemented carbide steel ball.
[0019] Secondly, this application provides a driver controller, including a limit seat and a reversing shaft, and also includes a reversing handle;
[0020] The square opening of the handle plate is fitted onto the square structure corresponding to the end of the reversing shaft. The handle plate and the small handle are integrally set inside the limiting seat. The steel ball of the ball plunger cooperates with the positioning groove preset inside the limiting seat.
[0021] Thirdly, this application provides a control method for a driver controller of a reversing handle with a ball-head plunger, comprising:
[0022] Operate the small handle to drive the reversing shaft to rotate within the limiting seat via the handle plate;
[0023] When rotated to the target reversing position, the steel ball of the ball plunger is engaged in the corresponding positioning groove on the limiting seat under the action of the internal spring, thereby achieving positioning and tactile feedback.
[0024] The technical solution provided in this application can achieve at least the following beneficial effects:
[0025] This application provides a reversing handle with a ball-head plunger, a driver controller, and a control method thereof. It applies an innovative ball-head plunger positioning structure to the reversing handle of a rail transit driver controller. By constructing a handle structure with elastic self-locking, modular assembly, and high interchangeability, it achieves precise control and long-term stability of the reversing operation. This solves the problems of complex processing, easy wear and jamming, poor interchangeability, and difficult maintenance inherent in traditional mechanical hexagonal structures. It transforms the previous "one machine, one adjustment; maintenance dependent on manual labor" operation and maintenance model, establishing a unified and reliable reversing handle structure standard, and realizing the systematization and standardization of the driver controller at both the structural and maintenance levels.
[0026] The reversing handle with ball-head plunger is designed for the high vibration and high reliability conditions of rail transit. It can adapt to long-term frequent operation and complex operating environment, providing the driver with clear and stable tactile feedback and position holding. This structure has good scalability and adaptability, and can quickly adjust the handle size and connection form according to the requirements of different vehicle models and different control interfaces. It helps to solve the problems of loosening and inaccurate positioning of traditional handles, and improves the overall reliability and operational safety of the system.
[0027] Based on the existing driver controller structure and operational requirements, a ball-head plunger was adopted instead of the complex internal hexagonal fit structure. This eliminated the previous manufacturing model that relied on high-precision machining and optional assembly, improving production efficiency and product consistency. Using this structure significantly improved handle assembly efficiency, increased parts standardization, and effectively reduced production costs. Attached Figure Description

[0034] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0035] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0036] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.
[0037] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.
[0038] The driver controller is a control device for railway locomotives, EMUs, and industrial automation. It is mainly used to control the locomotive's reversing and diesel engine / electric motor speed regulation, thereby controlling the locomotive's running direction, power, traction, and speed. The driver controller is directly installed on the driver's console, with its main body located below the console panel and hidden inside the console. Its human-machine interface, i.e., the handle, is exposed above the console panel.
[0039] Traditional driver controller reversing handles use a mechanical hexagonal structure, which results in complex structure, difficult processing, complex production process, high cost, poor interchangeability, and easy mechanical wear during use, leading to jamming. This results in insufficient reliability and maintainability, affecting the normal operation of the locomotive.
[0040] Therefore, there is an urgent need for a reversing handle structure that is simplified, reliable in positioning, easy to maintain, and adaptable to high-intensity vibration environments.
[0041] Next, the technical solutions of this application and how they solve the aforementioned technical problems will be described in detail through embodiments and in conjunction with the accompanying drawings. The embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application.
[0042] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, a reversing handle with a ball plunger is provided. In this embodiment, the reversing handle may include a small handle, a handle plate, a ball plunger, and a screw.
[0043] One end of the handle plate is provided with a mounting part, and the small handle is fixedly connected to the mounting part by the screw;
[0044] The other end of the handle plate is provided with a square opening for connecting to the reversing shaft, and the front end of the square opening is chamfered.
[0045] The side wall of the handle plate is formed with a circular positioning shoulder through a diameter expansion process;
[0046] The ball plunger is equipped with a spring and a steel ball inside, and the ball plunger is pressed and fixed to the circular positioning shoulder.
[0047] In one embodiment, the reversing handle provided in some embodiments of this application has the following core components: a small handle 1, a handle plate 2, a ball plunger 3, and a screw 4.
[0048] The handle plate 2 is a key component for connection and transmission. One end of it is provided with a mounting part, specifically a radial threaded hole perpendicular to the surface of the handle plate. The base of the small handle 1 is provided with a corresponding through hole. The screw 4 passes through the through hole and is screwed into the radial threaded hole, thereby achieving a fixed connection between the small handle 1 and the handle plate 2. To ensure a more reliable connection and prevent relative rotation between the small handle 1 and the handle plate 2 due to vibration during use, a positioning pin can be added between the base of the small handle 1 and the mounting surface of the handle plate 2. This positioning pin can be inserted into the corresponding pin holes of the small handle and the handle plate.
[0049] The other end of the handle plate 2 is machined with a square opening. The size of this square opening matches the square shaft head at the end of the reversing shaft 6 in the driver controller, and is used to transmit torque. To facilitate alignment during assembly, the front end of the square opening is chamfered. The chamfer angle is preferably 30°, but according to process requirements, a good guiding effect can be achieved in the range of 15° to 45°.
[0050] The sidewall of the handle plate 2 is partially protruded outward to form a circular positioning shoulder through a diameter expansion process in machining. A hole perpendicular to the sidewall of the handle plate is machined at the center of this circular positioning shoulder. The ball plunger 3 is pressed into and fixed in this hole. To ensure that the ball plunger 3 is firmly installed and does not loosen, the hole on the circular positioning shoulder and the outer shell of the ball plunger 3 are interference-fitted. The interference amount can be selected according to the material properties, for example, within the fit tolerance range of H7 / p6.
[0051] The ball plunger 3 is a standard or customized part, internally encapsulated with a spring and steel balls. The steel balls are partially exposed in the housing and can elastically expand and contract under the preload of the internal spring. To adapt to the high vibration and frequent operation environment of rail transit, the spring is preferably a compression spring made of stainless steel, which has corrosion resistance and a stable elastic coefficient. The steel balls are preferably made of hard alloy steel balls, with the surface treated by quenching and grinding, which has extremely high hardness and wear resistance.
[0052] In addition, the main body of the handle plate 2 is designed to be flat, with its thickness being much smaller than its width, and its cross-section being oblong or rectangular. This structure facilitates gripping and applying force, and also makes it easier to arrange in a limited installation space. The surface of the handle plate 2 can be sandblasted, oxidized, or coated with a wear-resistant and anti-slip coating (such as rubber paint) to improve the feel and increase friction.
[0053] Corresponding to the aforementioned embodiment of the reversing handle with ball-head plunger, and employing the same technical concept, this application also provides an embodiment of a driver controller.
[0054] In one exemplary embodiment, such as Figure 2 As shown, the driver controller includes a limit seat and a reversing shaft, and also includes a reversing handle;
[0055] The square opening of the handle plate is fitted onto the square structure corresponding to the end of the reversing shaft. The handle plate and the small handle are integrally set inside the limiting seat. The steel ball of the ball plunger cooperates with the positioning groove preset inside the limiting seat.
[0056] In one embodiment, the practical application of the reversing handle provided in some embodiments of this application in a driver controller is disclosed.
[0057] A driver controller including the reversing handle mainly includes: a limit seat 5, a reversing shaft 6, and a reversing handle as described in Embodiment 1.
[0058] During assembly, align the square opening of the handle plate 2 with the square shaft head at the end of the reversing shaft 6 and slide it onto it axially. Then, place the assembled handle plate 2 and the small handle 1 together into the reserved cavity of the limiting seat 5. The limiting seat 5 is fixedly installed below the driver's control panel, and its interior has several positioning grooves pre-machined according to the "forward", "neutral", "reverse" and other gear positions.
[0059] Corresponding to the aforementioned embodiment of the reversing handle with ball-head plunger, and employing the same technical concept, this application also provides an embodiment of a control method for a driver controller of a reversing handle with ball-head plunger.
[0060] In one exemplary embodiment, such as Figure 3 As shown, the control method of the driver controller for the reversing handle with the ball-head plunger may include the following steps:
[0061] Operate the small handle to drive the reversing shaft to rotate within the limiting seat via the handle plate;
[0062] When rotated to the target reversing position, the steel ball of the ball plunger is engaged in the corresponding positioning groove on the limiting seat under the action of the internal spring, thereby achieving positioning and tactile feedback.
[0063] In one embodiment, the reversing control method is as follows when the driver needs to operate the system:
[0064] Step 100: The operator applies torque by manually turning the small handle 1.
[0065] Step 200: The torque is transmitted through the handle plate 2 to the reversing shaft 6 that is sleeved with it, driving the reversing shaft 6 to rotate within the limit seat 5.
[0066] Step 300: When the reversing shaft 6 drives the handle plate 2 to rotate to the target position (e.g., the "forward" position), the steel ball of the ball plunger 3 is pushed by the internal spring and just gets into the corresponding positioning groove on the inner wall of the limit seat 5.
[0067] Step 400: At this point, the operator can feel a clear "click" sensation (tactile feedback), and the handle is held in place by elastic force, achieving precise positioning and effectively preventing accidental displacement caused by vehicle vibration.
[0068] Step 500: When a change of direction is required, the operator only needs to apply a torque sufficient to overcome the pressure of the ball plunger spring to dislodge the steel ball from the groove, and then continue to turn the handle to the next position.
[0069] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially as indicated, these steps are not necessarily executed in the indicated order. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps.
[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.
[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
