Description

Technical Field

[0001] This utility model relates to the field of train technology, and in particular to a rapid docking and calibration device for a diesel locomotive coupler. Background Technology

[0002] The diesel locomotive coupler is a key device connecting the locomotive and the carriages. It is responsible for transmitting traction and braking forces and absorbing shocks during operation to ensure stable train operation. However, the traditional manual connection method is inefficient, lacks precision, and has poor safety. Especially in complex terrain, it is prone to wear or disengagement due to uneven force. Therefore, the rapid docking calibration device has emerged. Through a mechanical structure, it can achieve rapid and accurate connection of the coupler, automatically adjust the levelness and uniformity of force, greatly improve shunting efficiency, and significantly enhance operational safety. It is an important advancement in modern railway transportation technology.

[0003] A search revealed that the document with publication number "CN220535649U" states: "This utility model relates to the field of train technology, providing a train coupler locking device, including a first locking frame, a first insert block, and a second locking frame. A second locking frame is provided on one side of the first locking frame, a second insert block is provided at one end of one side of the first locking frame, and a second locking frame is provided on one side of one end of the second locking frame. A locking structure is provided inside both the first and second locking frames, and a fixing structure is provided at the top of both the first and second locking frames. The locking structure includes a connecting plate, a return spring, a fixing ring, a locking semicircular block, a movable groove, and a connecting post. This utility model..." The connecting plate, return spring, fixing ring, and locking semicircular block work together to lock the first and second locking frames. This allows the inner fixing ring of the first locking frame to engage with the inner fixing ring of the second locking frame, thus securing both frames and making locking more convenient.

[0004] However, existing coupler docking devices lack guidance functions, and deviations are prone to occur when the coupler enters the docking slot, resulting in low docking accuracy. This can lead to docking failure and require multiple adjustments to complete the docking. In addition, existing coupler docking devices rely solely on mechanical interlocking for connection, which can easily loosen when the train is subjected to external impacts during operation, posing a risk of uncoupling.

[0005] Therefore, we provide a rapid docking and calibration device for diesel locomotive couplers to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a rapid docking calibration device for diesel locomotive couplers, including a connecting base 1, a fixing hole 2 on the surface of the connecting base 1, an mounting plate 3 fixedly connected to the right side of the connecting base 1, a docking groove 4 on the inner side of the mounting plate 3, and a guide component 5 installed thereon. The guide component 5 includes a fixing shaft 501 mounted on the upper surface of the mounting plate 3, a guide roller 502 on the surface of the fixing shaft 501, and a docking component 6 on the inner side of the docking groove 4. The docking component 6 includes a first triangular locking block 601 disposed on the inner side of the docking groove 4, and a connecting shaft 602 disposed on the left side of the first triangular locking block 601.

[0033] Furthermore, there are eight sets of fixing holes 2, the connection between the base 1 and the mounting plate 3 is welded, and there are two sets of docking grooves 4. The eight sets of fixing holes 2 can provide more installation options and a more stable fixing effect, ensuring the robustness of the device in different installation environments. The welding connection between the base 1 and the mounting plate 3 enhances the strength and stability of the structure, enabling the device to withstand greater external forces and wear during long-term use. The design of the two sets of docking grooves 4 can simultaneously meet the docking requirements of two sets of couplers, improving the applicability and working efficiency of the device.

[0034] Furthermore, the fixed shaft 501 and the guide rollers 502 are rotatably connected. Both the fixed shaft 501 and the guide rollers 502 are provided with eight sets. When components such as couplers need to be docked, the guide rollers 502 rotate on the fixed shaft 501, guiding the couplers and other components into the docking slot 4 in the correct direction, completing the pre-docking guidance work. The eight sets of rotatably connected fixed shafts 501 and guide rollers 502 can provide multi-directional guidance, ensuring that components such as couplers can accurately enter the docking slot 4 from different angles. This design of multiple sets of guide rollers 502 improves the reliability of guidance, reduces deviations and errors in the docking process, improves the success rate and efficiency of docking, and also reduces the risk of damage caused by inaccurate docking.

[0035] Furthermore, a torsion spring 603 is sleeved on the surface of the connecting shaft 602, and a second triangular locking block 604 is provided on the right side of the connecting shaft 602. When components such as the coupler enter the docking groove 4 and contact the first triangular locking block 601 and the second triangular locking block 604, the first triangular locking block 601 and the second triangular locking block 604 retract due to the action of the connecting shaft 602 and the torsion spring 603, smoothly passing through the docking groove 4 and entering the top of the docking groove 4. The top of the docking groove 4 is triangular. When the first triangular locking block 601 and the second triangular locking block 604 enter the top of the docking groove 4, the torsion spring 603 rebounds, causing the first triangular locking block 601 and the second triangular locking block 604 to unfold and engage with the docking groove 4, thereby improving the stability and safety of the docking.

[0036] Furthermore, the first triangular locking block 601 and the second triangular locking block 604 have the same shape but opposite directions. The first triangular locking block 601 and the second triangular locking block 604 form an elastic rotation structure through the connecting shaft 602 and the torsion spring 603. The first triangular locking block 601 and the second triangular locking block 604 with the same shape and opposite directions can achieve precise engagement, ensuring stable connection of the components after docking. The design of the elastic rotation structure further improves the reliability of engagement.

[0037] Furthermore, a docking post 605 is provided on the outer side of the second triangular block 604, and a docking base 606 is fixedly connected to the right end of the docking post 605. The docking post 605 and the docking base 606 provide a stable connection point for components such as couplers, ensuring the firmness after docking. This structural design can withstand greater tension and pressure, ensuring the stable connection of components such as couplers during operation, and improving the safety and reliability of train operation.

[0038] Furthermore, the surface of the docking base 606 is provided with threaded holes, and the docking post 605 is connected to the first triangular block 601 and the second triangular block 604 through the connecting shaft 602. The design of the threaded holes provides the docking base 606 with a connection method to the locomotive diesel engine. The threaded connection can achieve a more secure connection, improve the stability and reliability of the device, and this connection method is also convenient for installation and disassembly, and facilitates the maintenance and repair of the device.

[0039] Working principle: The device is installed in the working position, and then the connecting base 1 is firmly installed on the relevant part of the train car through the eight sets of fixing holes 2 on its surface. The connecting base 1 and the mounting plate 3 are connected by welding to enhance the structural strength. When the docking component 6 needs to dock, the docking component 6 approaches the docking groove 4 of the mounting plate 3. The eight sets of fixing shafts 501 and guide rollers 502 installed on the upper surface of the mounting plate 3 begin to guide the docking component 6 into the docking groove 4 in the correct direction. After the docking component 6 enters the docking groove 4, it contacts the first triangular locking block 601 and the second triangular locking block 604. At this time, the connecting shaft 602 and the torsion spring 603 cause the first triangular locking block 601 and the second triangular locking block 604 to retract, allowing the docking component 6 to pass smoothly and enter the top of the docking groove 4. Subsequently, the torsion spring 603 rebounds, causing the first triangular locking block 601 and the second triangular locking block 604 to unfold and engage with the triangular groove at the top of the docking groove 4. This completes the use of a rapid docking calibration device for a diesel locomotive coupler.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
