Description

Technical Field

[0001] This utility model specifically relates to a driver controller. Background Technology

[0002] The driver controller is a control device for railway locomotives, EMUs, and industrial automation, serving as the master electrical control for locomotive reversing and speed regulation. It is a manual electrical device used by the driver to operate the locomotive, primarily controlling reversing, diesel engine speed regulation, and consequently, the locomotive's direction of travel, power, traction, and speed. Currently, the driver controllers used in domestically produced electric and diesel locomotives are largely modified from civilian electrical systems, with exposed contacts, failing to meet the high-density, high-capacity, and high-vibration requirements of special environments such as railways, oil fields, and mines. Furthermore, existing driver controllers suffer from complex structures, unreliable performance, high failure rates, and short service lives. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a driver controller that is simple in structure, stable and reliable in performance, has a low failure rate, and a long service life.

[0004] To achieve the above objectives, this utility model employs a driver controller, including a frame, a control panel, a reversing handle assembly, and a speed control handle assembly. The reversing handle assembly includes a reversing shaft rotatably mounted within the frame, a reversing handle mounted on the reversing shaft, multiple reversing cams linked to the reversing shaft, multiple microswitches mounted on the frame and cooperating with the multiple reversing cams, and an interlocking limit wheel linked to the reversing shaft. The speed control handle assembly includes a speed control shaft rotatably mounted within the frame, a speed control handle mounted on the speed control shaft, and multiple interlocking limit wheels linked to the reversing shaft. The system includes a bevel gear mounted on a speed-regulating shaft, a speed-regulating camshaft rotatably mounted within a mechanism frame, a potentiometer linked to the speed-regulating camshaft, multiple speed-regulating cams mounted on the speed-regulating camshaft, a speed-regulating micro switch mounted on the mechanism frame and cooperating with the multiple speed-regulating cams, a gear linked to the speed-regulating camshaft and meshing with the bevel gear, and an interlocking wheel linked to the speed-regulating camshaft and cooperating with the interlocking limit wheel. The interlocking limit wheel is provided with multiple locking grooves, and the interlocking wheel is engaged in the locking grooves, thus forming a limiting cooperation between the interlocking wheel and the interlocking limit wheel.

[0005] The advantages of the above structure are as follows: the reversing handle assembly and the speed control handle assembly adopt modular structural designs, which facilitates modular assembly of the driver controller, making assembly more convenient. Furthermore, both the reversing handle assembly and the speed control handle assembly employ gear transmission structures, resulting in smoother and more reliable transmission and a longer service life. Additionally, the speed control camshaft is interlocked with the interlocking limit wheel on the camshaft via an interlocking wheel, preventing misoperation and ensuring the safe and stable operation of the locomotive. Therefore, this driver controller has the advantages of simple structure, stable and reliable performance, low failure rate, and long service life.

[0006] Specifically, the mechanism frame is equipped with a limiting spring that cooperates with the interlocking limiting wheel. One end of the limiting spring is rotatably connected to a limiting roller that cooperates with the interlocking limiting wheel. The interlocking limiting wheel is provided with multiple arc-shaped limiting grooves that cooperate with the limiting rollers. When the reversing shaft rotates, the limiting rollers reciprocate within these arc-shaped limiting grooves. The limiting spring, through its cooperation with the limiting roller and the interlocking limiting wheel, ensures reliable operation of the interlocking limiting cam on the camshaft, thereby improving the operational reliability of the driver controller.

[0007] Specifically, the control panel is provided with a cover corresponding to the speed control handle. The cover has a speed control hole through which the speed control handle can pass. An arc-shaped baffle is slidably disposed inside the cover, blocking the speed control hole. The arc-shaped baffle has a through hole through which the speed control handle can pass. The arc-shaped baffle moves with the speed control handle and slides back and forth in the speed control hole. The arc-shaped baffle can prevent debris from being moved from the speed control hole into the speed control handle assembly, thereby improving the working reliability of the driver controller.

[0008] Specifically, a limiting component is linked to the speed regulating shaft, and a speed regulating limiting spring that cooperates with the limiting component is provided on the mechanism frame. The speed regulating limiting spring is provided with a speed regulating roller that cooperates with the limiting component, and the limiting component is provided with an arc-shaped positioning groove that cooperates with the speed regulating roller. The speed regulating shaft, through the cooperation of the limiting component and the speed regulating limiting spring, ensures reliable operation of the speed regulating shaft and provides a clearer gear shift feel, thereby improving the operational reliability of the driver controller.

[0009] Specifically, the control panel has a groove corresponding to the reversing handle, and a cold light sheet and a reversing indicator are arranged sequentially in the groove. A cold light sheet is located below the reversing indicator for nighttime illumination; the use of a cold light sheet provides uniform and soft light, has a long lifespan, is more aesthetically pleasing, and helps reduce potential points of failure and lower the failure rate.

The interlocking limiting wheel 25 is respectively provided with multiple arc-shaped limiting grooves 252 that cooperate with the limiting rollers 261. When the reversing shaft 21 rotates, the limiting rollers 261 reciprocate within the multiple arc-shaped limiting grooves 252. The limiting spring cooperates with the interlocking limiting wheel through the limiting roller, thereby ensuring that the interlocking limiting cam can reliably move on the camshaft, which helps to improve the working reliability of the driver controller.

The arc-shaped baffle 13 is provided with a through hole 131 through which the speed control handle 32 can pass. The arc-shaped baffle moves with the speed control handle and slides back and forth in the speed control hole. The arc-shaped baffle can prevent foreign objects from entering the speed control handle assembly from the speed control hole, thereby improving the working reliability of the driver controller.

[0015] A limiting component 311 is linked to the speed regulating shaft 31, and a speed regulating limiting spring 312 that cooperates with the limiting component 311 is provided on the mechanism frame 10. A speed regulating roller 313 that cooperates with the limiting component 311 is provided on the speed regulating limiting spring 312, and an arc-shaped positioning groove 3111 that cooperates with the speed regulating roller 313 is provided on the limiting component 311. The speed regulating shaft, through the cooperation of the limiting component and the speed regulating limiting spring, ensures reliable operation and clearer gear shifting, thereby improving the reliability of the driver controller.

A cold light sheet is provided below the reversing indicator for nighttime illumination; the use of a cold light sheet provides uniform and soft light, has a long lifespan, and a more aesthetically pleasing appearance, while also reducing potential failure points and lowering the failure rate.

[0016] The reversing handle assembly and speed control handle assembly both adopt a modular design, facilitating modular assembly of the driver controller and making assembly more convenient. Both assemblies utilize gear transmission, resulting in smoother, more reliable transmission and a longer service life. Furthermore, the speed control camshaft is interlocked with an interlocking limit wheel on the camshaft via an interlocking wheel, preventing misoperation and ensuring the safe and stable operation of the locomotive. Therefore, this driver controller boasts advantages such as simple structure, stable and reliable performance, low failure rate, and long service life.
