Description

TECHNICAL FIELD

[0001] The application relates to a coupler for railway locomotive trailer operation and belongs to the technical field of railway locomotive connection. BACKGROUND

[0002] As a core component for ensuring safe and stable connection between a trailer and a tractor, the performance and efficiency of the coupler are crucial. The current widely used snap ring connector in railway locomotive trailer operation is relatively traditional in design and mainly consists of two snap rings equipped with threaded interfaces. The two snap rings are ingeniously placed around the shaft shoulder of the components to be connected, and then tightly connected and fixed together through bolts, thereby establishing physical connection between the trailer and the tractor.

[0003] However, this snap ring connector has some significant defects in actual application. The installation process is relatively cumbersome and requires workers to perform multiple steps, which undoubtedly increases the labor intensity of workers and reduces the operation efficiency. Although the bolt connection method can ensure the stability of the connection to a certain extent, the bolts may loosen due to vibration, wear and other factors during long-term use, thereby causing safety hazards.

[0023] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0024] See Figures 1-4 A coupling for railway locomotive trailer operations, characterized in that it comprises:

[0025] A connecting shaft 1 is provided, one end of which is connected to the locomotive and the other end of which is connected to the trailer. Two clamping plates 2 are symmetrically arranged on the outer side of the connecting shaft. One end of the two clamping plates 2 is rotatably connected to the connecting shaft 1, and the other end is in a hugging shape to clamp the connecting end of the connecting shaft 1 to the locomotive.

[0026] An adjusting screw 3 is connected between the two clamping plates 2. The opening and closing degree of the clamping plates 2 can be adjusted by rotating the adjusting screw 3.

[0027] Specifically, one end of the connecting shaft is connected to the locomotive, and the other end is connected to the trailer. The connecting shaft needs to be sufficiently robust to withstand the traction force and various dynamic loads between the locomotive and the trailer. Two clamping plates are symmetrically arranged on the outside of the connecting shaft, with one end rotatably connected to the connecting shaft, allowing the clamping plates to rotate moderately on the connecting shaft. The other end of the clamping plates is in a clamping shape, which, when the clamping plate opening is properly adjusted, can tightly clamp the part of the connecting shaft connected to the locomotive, ensuring the stability of the connection. An adjusting screw 3 is connected between the two clamping plates. By rotating the adjusting screw, the clamping plates move along the adjusting screw, thereby adjusting the clamping plate opening. This ensures that the connecting shaft and the locomotive connection end are in a stable connected state or a disconnected state.

[0028] Before towing, one end of the connecting shaft must be securely connected to the locomotive, and the other end to the trailer. Then, by adjusting the rotation of the adjusting screw, the two clamps gradually open or close. When the clamps are closed, they tightly grip the connection between the connecting shaft and the locomotive, forming a stable mechanical connection. The adjusting screw is designed to allow operators to adjust it on-site according to actual conditions, ensuring a tight and secure connection.

[0029] The two ends of the adjusting screw 3 pass through the clamping plate 2 and are connected to the motor 5 via the rotating nut 4;

[0030] A nut support 6 is provided on the outer side of the clamping plate 2, and the rotating nut 4 is installed on the nut support 6.

[0031] The rotating nut 4 is mounted on the adjusting screw 3. By rotating the adjusting screw 3, the rotating nut 4 moves on the adjusting screw 3, thereby clamping the clamping plate 2.

[0032] Specifically, rotating nuts are installed at both ends of the adjusting screw. When the motor starts, it drives the adjusting screw to rotate, causing the clamping plate to move on the adjusting screw by rotating the nut, thereby adjusting the clamping degree. The motor provides power to the adjusting screw, and by controlling the rotation direction and speed of the motor, the rotation speed of the adjusting screw can be precisely adjusted. The introduction of the motor enables automated control of the adjusting screw, improving the efficiency and accuracy of connection and disconnection. Nut supports are located on the outside of the clamping plate to support and fix the rotating nut. By keeping the nut supports relatively fixed to the clamping plate, it is ensured that the rotating nut can move stably on the adjusting screw when the motor rotates.

[0033] The motor drives the adjusting screw to rotate, and then the rotating nut fitted on the adjusting screw moves along the adjusting screw, thereby causing the clamp to open and close. The rotating nut has an internal thread on its inner side, which engages with the thread on the adjusting screw.

[0034] The connecting shaft 1 is radially provided with a mounting hole 7, and the adjusting screw 3 passes through the mounting hole 7 and is connected to the clamping plate 2.

[0035] Specifically, the mounting hole is a key feature on the connecting shaft, and its position and size are designed to match the adjusting screw and the clamping plate. Through the mounting hole, the adjusting screw can pass precisely through the connecting shaft and connect with the clamping plate, thereby achieving adjustment of the clamping plate's tension.

[0036] The adjusting screw 3 has threads at both ends, and the threads at both ends turn in opposite directions;

[0037] Along the closing direction of the clamping plate 2, the thread on the adjusting screw 3 is a helical helix thread.

[0038] Specifically, the two ends of the adjusting screw employ an opposite thread direction design. Rotating the adjusting screw allows for simultaneous adjustment of both clamps, ensuring they move synchronously (towards or away from each other) during adjustment, thus improving connection stability and accuracy. When the adjusting screw is rotated to clamp the clamps, the threads utilize a helix angle design. This helix angle provides better self-locking performance, preventing loosening under vibration or impact loads. Furthermore, the helix angle design also helps reduce friction between the threads, making the adjustment process smoother.

[0039] It is worth noting that when the clamping plate opening and closing needs to be adjusted, the motor is started, and the motor drives the adjusting screw to rotate. Since the threads at both ends of the adjusting screw turn in opposite directions, rotation causes the rotating nuts at both ends to move simultaneously in opposite directions, thereby pushing the two clamping plates to open or close synchronously. The helical helix thread design ensures stability and self-locking performance during the adjustment process, preventing loosening of the threads and instability of the connection. In this application, the threads at both ends of the adjusting screw can be implemented using existing designs to achieve reverse helixes and self-locking performance.

[0040] One end of the connecting shaft 1 is adapted to the connecting end of the locomotive, and both the connecting shaft 1 and the connecting end of the locomotive are provided with a convex ring 8. The other end of the clamping plate 2 is provided with a groove 9 that matches the convex ring 8. The convex ring 8 is located in the groove 9 to achieve clamping.

[0041] Specifically, the convex ring is a key feature on the connecting shaft and the locomotive connection end, improving the stability and reliability of the connection. The shape, size, and position of the convex ring ensure a perfect match with the grooves on the clamping plate.

[0042] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
