Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a coupler uncoupling device and a coupler. Background Technology

[0002] The CG-5 coupler is a commonly used close-coupled type, widely applied in urban rail transit systems such as those in Beijing and Tianjin. The CG-5 coupler features a long coupling guide and a small coupling gap. Currently, the manual uncoupling method for the CG-5 coupler is via a side handle, requiring the operator to stand to the side of the coupler on the track. After uncoupling, the locking lever must be manually operated to lock the uncoupling position. For trains such as monorails, suspended tracks, and maglev trains where track surface operation is not possible, the use of the CG-5 coupler is limited because it is impossible to disembark on the track.

[0003] For example, patent CN206589896U discloses a coupler coupling and uncoupling assembly, including an uncoupling linkage and an uncoupling handle, with the uncoupling handle located on the side of the coupler. While patent CN21447588U discloses a novel subway vehicle close-fitting automatic coupler anti-miscoupling device, although its uncoupling lever is located above the coupler head, it still guides the uncoupling handle to the side of the coupler via an uncoupling rope, achieving unlocking from the side of the coupler. Furthermore, the coupler uncoupling structures disclosed in the aforementioned patents all lack a locking structure for the uncoupling state.

[0004] Currently, high-speed maglev trains use CG-5 couplers to achieve flexible and close train formation. However, the operating environment of high-speed maglev trains makes side-coupled coupling operations unsuitable. There is currently a lack of solutions to this technical problem in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the aforementioned technical problems, and to provide a device for uncoupling a train coupler, and the application of the uncoupling device on a train coupler, wherein the uncoupling device can perform the uncoupling operation from above the train coupler.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A coupler includes a coupler head, a coupler tongue, and an uncoupling device. The coupler head includes multiple coupler head wall plates forming a coupler head cavity. The coupler tongue is disposed inside the coupler head cavity. The uncoupling device includes:

[0008] Handle: The first end is connected to the hook tongue, and the second end extends to the outside of the hook head cavity through a slotted structure on the side wall of the hook head; the handle can move along the extension direction of the slotted structure to drive the hook tongue to rotate;

[0009] Fixed plate: Installed on the hook head wall panel, located above the hook head slot structure, with part of the plate surface extending to the outside of the hook head, including the first plate hole, and the first plate hole is set on the plate surface of the fixed plate located on the outside of the hook head;

[0010] Handle drive rope: Attached to the handle and passes through the first plate hole to the top of the hook.

[0011] In some embodiments of the present invention, a locking rod is further included, which is installed on the hook side wall plate on the same side as the hook slot structure. The locking rod body is provided with a locking slot facing the slot structure. The shape and size of the locking slot are configured to accommodate the handle and restrict the movement of the handle.

[0016] The shaft connection between the linkage rod and the fixed plate is located outside the first plate hole. The outside of the first plate hole is the side away from the second plate hole. After the handle drive rope passes through the first plate hole, it is located on the same side as the locking rod drive rope, so that when the handle drive rope moves along the first plate hole, it can drive the linkage rod to move.

[0017] In some embodiments of the present invention, the fixed plate is provided with at least one side motion limiting post, which is located on the rotational travel trajectory of the linkage rod.

[0018] In some embodiments of the present invention, a locking rod limiting post is provided on the hook side wall plate on the mounting side of the locking rod.

[0019] In some embodiments of the present invention, a steering pulley is further included, mounted below the fixed plate. The groove of the pulley is located in a vertical plane, and the handle drive rope is located in the pulley groove, guided by the steering pulley, and passes through the hole in the first plate.

[0020] In some embodiments of the present invention, the second end of the handle is provided with an opening groove, a cotter pin is installed in the opening groove, and the handle drive rope is connected to the cotter pin.

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] In the description of this application, it should be noted that: the fixed connection described in this application can be a detachable fixed connection or an integrated fixed connection; the indication of orientation or positional relationship is based on the positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] The terms "first" and "second" are used only to describe the purpose and are not used to imply relative importance.

[0048] This invention provides a coupler, specifically a CG-5 type coupler. As the basic structure of the coupler, it includes a coupler head 1, a coupler tongue (not visible in the accompanying drawings), and a disengagement device. The disengagement device is used to drive the coupler from an engaged state to an unengaged state.

[0049] The hook head 1 includes multiple hook head wall panels, which form a hook head cavity. In this embodiment, the CG-5 type coupler includes upper and lower hook head wall panels and left and right side wall panels 103. The hook head cavity has a front-wide, rear-narrow structure, with the front end serving as the coupling end and the rear end for connecting to the vehicle body. The hook tongue is located inside the hook head cavity, and coupling is achieved through the hook tongue connection between the two couplers.

[0050] refer to Figure 1 The specific details of the unhooking device are as follows.

[0051] Handle 2 is used for unhooking operations. Its first end connects to the hook tongue inside the cavity (not visible in the figure), and its second end extends to the outside of the hook head cavity through a slot 101 structure on the side wall plate of the hook head. The slot 101 is an elongated hole extending along the length of the coupler, and handle 2 is rod-shaped. Handle 2 can move along the extension direction of the slot structure to drive the hook tongue to rotate.

[0052] In this embodiment, the slot 101 is a rectangular hole, and the part of the handle 2 that mates with the slot 101 has a rectangular outer surface that matches the size of the slot 101, so that the handle 2 can move stably within the space defined by the slot 101.

[0053] The fixing plate 3 is installed on the hook head wall panel, located above the hook head slot 101 structure, and its hook unhooking reference Figure 4 In this embodiment, the fixing plate 3 is a rectangular plate, which is installed on the hook head wall plate 102 by fixing bolts, and part of the plate surface of the fixing plate 3 extends to the outside of the hook head wall plate 102.

[0054] The fixing plate 3 includes a first plate hole 301, which is located on the plate surface of the fixing plate 3 that extends to the outside of the hook head 1.

[0055] The handle drive rope 4 is connected to the handle 2 and passes through the first plate hole 301 to the top of the hook. The handle drive rope 4 can be made of steel wire rope. To facilitate the operation of the handle drive rope 4, an operating lever 9 can be designed, which is connected to the end of the handle drive rope 4 that passes through the slot hole 101. The handle drive rope 4 is operated by pulling the operating lever 9. To facilitate the fixing of the handle drive rope 4 and the operating lever 9, a fixing clip 11 is provided at the end of the operating lever 9 that passes through the first plate hole 301 to prevent the operating lever 9 from falling off.

[0056] To facilitate the installation of the handle drive rope 4 and the handle 2, an open slot is provided at the second end of the handle 2, and a cotter pin 10 is installed in the gap of the open slot. The handle drive rope 4 is connected to the cotter pin 10.

[0057] Pulling the handle drive rope 4 above the hook head 1 will cause the handle 2 to rotate, which in turn will cause the hook tongue to rotate, thus completing the unhooking action.

[0058] By unhooking through the first plate hole 301 of the fixing plate 3, the direction of movement of the handle drive rope 4 is changed, thereby solving the problem of unhooking from above the hook head.

[0059] In some embodiments of the present invention, a locking rod 5 is further included, which is installed on the hook head sidewall plate 103 on the same side as the hook head slot hole 101 structure. The locking rod 5 has a locking groove 501 facing the slot hole structure. The shape and size of the locking groove 501 are configured to accommodate the handle 2 and restrict its movement. Specifically, the locking rod 5 is located below the slot hole structure and is a long plate. One end of it is axially connected to the hook head sidewall plate 103 as a rotating end. The locking groove 501 is provided on the side of the locking rod 5, facing upwards towards the hook head slot hole 101. When the handle 2 is pulled and rotated, the locking rod 5 is driven to rotate. When the handle 2 moves to the unhooked position, the locking groove 501 precisely engages the handle 2, preventing it from returning to its original position and keeping the hook locked in the unhooked position.

[0060] A torsion spring is provided at the shaft connection end between the locking rod 5 and the side wall plate 103 of the coupler, so that the locking rod 5 can automatically reset after rotation.

[0061] To facilitate the operation of the locking lever 5, some embodiments of the present invention further include a locking lever drive rope 6 connected to the locking lever 5 to drive the locking lever to rotate.

[0062] In some embodiments of the present invention, a second plate hole 302 is provided on the fixing plate 3, and the second plate hole 302 is also located on the plate surface of the fixing plate 3 extending outside the hook head. The locking rod drive rope 6 passes through the second plate hole 302 and extends above the hook head 1. The movement of the locking rod 5 is driven by pulling the locking rod drive rope 6.

[0063] In some embodiments of the present invention, a locking rod limiting post 13 is provided on the hook head side wall plate 103 on the mounting side of the locking rod 5. The locking rod limiting post 13 is spaced apart from the axial connection position of the locking rod 5 and the hook head side wall plate 103 and is located below the locking rod 5. When the locking rod 5 is not engaged with the handle 2, it is in contact with the locking rod limiting post 13 and its movement is restricted by the locking rod limiting post 13.

[0064] Since the unhooking action of the coupler and the locking action of the handle 2 need to be performed synchronously, a synchronous motion drive mechanism for the locking rod 5 and the handle 2 is further designed.

[0065] In some embodiments of the present invention, the second plate hole 302 is spaced apart from the first plate hole 301 along the length direction of the fixing plate 3, wherein the second plate hole 302 is located on the side closer to the hook head relative to the first plate hole 301; the first plate hole 301 is an elongated hole that extends along the direction of the parallel slot hole 101 structure. The parallelism described here is not necessarily absolute, but is used to illustrate that both the first plate hole 301 and the slot hole 101 are arranged along an approximately parallel direction to the length of the hook head. The shape of the second plate hole 302 is not limited, as long as the main locking rod drive rope 6 can pass through it.

[0066] The coupler further includes a linkage rod 7 disposed on the upper surface of the fixed plate, which serves as a reference for uncoupling. Figure 5 The first end of the linkage rod 7 is shaft-connected to the fixed plate, and the second end is connected to the end of the locking rod drive rope 6 that passes through the hole 302 of the second plate of the fixed plate.

[0067] The shaft connection between the linkage rod 7 and the fixed plate 3 is located outside the first plate hole 301. The outside of the first plate hole 301 is the side away from the second plate hole 301. After the handle drive rope 4 passes through the first plate hole 301, it is located on the same side as the locking rod drive rope 6, so that when the handle drive rope 4 moves along the first plate hole, it can drive the linkage rod 7 to move.

[0068] Specifically, the linkage rod 7 is fitted to the surface of the fixing plate 3. Its first end in the longitudinal direction has a shaft connection hole 702, which is fitted onto the shaft connection post 303 of the fixing plate and shaft-connected to the fixing plate 3. The shaft connection position is located outside the first plate hole 301. Its second end in the longitudinal direction has a through hole 701, which is connected to the locking rod drive rope 6.

[0069] The linkage rod 7 covers part of the first plate hole 301, but the width of the linkage rod 7 needs to be less than the length of the first plate hole 301, so that when the handle drive rope 4 moves along the first plate hole 301, it acts on the linkage rod 7 and drives the linkage rod 7 to rotate around its axis connection position with the fixed plate 5.

[0070] In some embodiments of the present invention, at least one side of the fixed plate 3 is provided with a motion limiting post located on the rotational travel trajectory of the linkage rod 7. As a preferred embodiment, a first motion limiting post 801 and a second motion limiting post 802 can be provided, with the two motion limiting posts respectively provided on both sides of the linkage rod 7, wherein the first motion limiting post 801 is close to the second plate hole 302, and the second motion limiting post 802 is close to the first plate hole 301.

[0071] The system further includes a steering pulley 12, mounted below the fixed plate. The groove of the steering pulley 12 is located in a vertical plane, and the handle drive rope 4 is located within the pulley groove. The function of the steering pulley 12 is to redirect the direction of the handle drive rope 4. To facilitate the installation of the steering pulley 12, a pulley mounting plate 304 is designed below the fixed plate 3. The pulley mounting plate 304 has mounting holes, and the wheel core of the steering pulley 304 is mounted at the position of the mounting holes.

[0072] The uncoupling operation process of the coupler provided by this invention is as follows.

[0073] refer to Figure 1 and Figure 2 When the vehicle is in the coupler-coupled state, handle 2 is located on the side closer to the end of the coupler.

[0074] refer to Figure 3 With the coupler uncoupled, pulling the operating lever 9 upwards pulls the handle drive rope 4, which in turn moves the handle 2 along the slot 101 towards the side where the hook head is attached. During this process, the direction of the handle drive rope 4 is controlled by the operating lever 9. While pulling the operating lever 9 upwards, the handle drive rope 4 slides along the first plate hole 301 towards the side near the hook tail. The handle drive rope 4 contacts the linkage rod 7, causing the shaft connection end of the linkage rod 7 and the fixed plate 3 to rotate. The linkage rod 7 pulls the locking rod drive rope 6, causing the locking rod 5 to rotate. Simultaneously, the handle 2 moves to the locking slot 501, achieving structural locking.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
