Description
Technical Field
[0001] This utility model belongs to the field of rail vehicle technology, and in particular relates to a coupler uncoupling device and a coupler. Background Technology
[0002] In traditional coupler structures, the uncoupling handle is usually installed on the coupler body. When uncoupling is required, the operator manually pulls the uncoupling handle, which causes the key components inside the coupler body, such as the hook tongue, to move. Under the traction of the uncoupling handle, the hook tongue rotates or moves outward, releasing the coupling state with the opposite coupler and realizing the separation of the two couplers.
[0003] In this uncoupling method, the uncoupling handle is fixed entirely by manual operation. The operator needs to continuously apply external force to pull the uncoupling handle to keep it in the fully open position until the vehicles are completely separated. The operation process is relatively cumbersome and the labor intensity of the operator is relatively high. In some special working conditions, such as uncoupling the train on a slope or in bad weather conditions, there are also significant safety risks. Utility Model Content
[0004] The purpose of this utility model is to solve one of the above-mentioned technical problems and to provide a coupler uncoupling device and a coupler.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A coupler uncoupling device, comprising:
[0007] The fastener is installed on the side of the coupler body where the unhooking handle is located, and the top of the fastener has a first inclined surface.
[0008] A rotating component is rotatably mounted on the side of the coupler body where the unhooking handle is not provided. The rotating component is provided with a second inclined surface, and the inclination angle of the second inclined surface matches the inclination angle of the first inclined surface.
[0009] When the two coupled couplers need to be uncoupled, the rotating part rotates until it engages with the fixing part of the opposite coupler, and its second inclined surface connects with the first inclined surface of the opposite fixing part.
[0010] When the uncoupling handle of the coupler is pulled to the fully open position, the uncoupling handle enters the interior of the rotating part of the opposite coupler, and the rotating part of the opposite coupler limits the uncoupling handle;
[0011] When the two couplers are separated after uncoupling, the first and second inclined surfaces slide relative to each other, and the rotating part is lifted by the fixed part, releasing the limit on the uncoupling handle.
[0012] In some embodiments of this utility model, a limit block is provided on the unhooking handle, and a corresponding limit groove is provided on the rotating part; when the unhooking handle of the coupler is pulled to the fully open position, the limit block is engaged in the limit groove.
[0013] In some embodiments of this utility model, the limiting groove and the second inclined surface are arranged on the same end face.
[0014] In some embodiments of this utility model, the rotating component and the hook body of the coupler are rotatably connected by a rotating shaft.
[0015] In some embodiments of this utility model, the fixing member and the rotating member are respectively arranged on both sides of the coupler connecting surface.
[0016] In some embodiments of this invention, the first inclined surface is inclined in the direction toward the unhooking handle.
[0017] In some embodiments of this utility model, the coupler includes a hook body, an inner cavity is provided inside the hook body, a hook tongue is provided inside the inner cavity, one end of the unhooking handle is connected to the hook tongue, and the other end extends out of the inner cavity of the hook body through a slot on the side wall of the hook body. The unhooking handle can move along the extension direction of the slot to drive the hook tongue to rotate.
[0018] In some embodiments of this utility model, the coupler further includes an elastic element, one end of which is connected to the unhooking handle and the other end of which is connected to the hook body.
[0019] In some embodiments of this invention, the elastic element is disposed within the inner cavity of the hook body.
[0020] In some embodiments of this utility model, the coupler is a close-fitting coupler.
[0021] Some embodiments of this utility model further provide a coupler, including the above-described coupler uncoupling device.
[0022] The beneficial effects of this utility model are as follows:
[0023] 1. This utility model limits the unhooking handle during the unhooking process by using the cooperation of rotating and fixing parts, ensuring that the unhooking handle remains in the correct position during the unhooking process, avoiding accidental movement of the unhooking handle due to external force or human factors. At the same time, the process does not require the operator to continuously apply external force to pull the unhooking handle to keep it in the fully open position, reducing labor costs and safety risks during the unhooking process.
[0024] 2. In this utility model, the rotating part and the fixed part are respectively provided with inclined surfaces, which are in contact and connected during the unhooking process, and slide relative to each other when the two couplers are separated, so that the rotating part is automatically lifted by the fixed part, releasing the limit on the unhooking handle. The unhooking handle is automatically reset under the action of the elastic part, which improves the convenience and automation of the unhooking operation, further reduces manual intervention, and reduces the operational risk.

[0054] The technical solution of this utility model will be described in detail below with reference to specific embodiments and the accompanying drawings.
[0055] As attached Figure 1 - Appendix Figure 15 As shown in an illustrative embodiment of a coupler uncoupling device of the present invention, the uncoupling device includes a fixing member 1 and a rotating member 2.
[0056] Among them, the fixing component 1 is a hook ramp, which is installed on the side of the hook body 3 where the hook release handle 4 is provided. The top of the fixing component 1 is provided with a first inclined surface 11, and the inclined direction of the first inclined surface 11 is towards the hook release handle 4, which is used to provide support for the rotating component 2 and limit the hook release handle 4 during the hook release process.
[0057] The rotating component 2 is a hook, rotatably mounted on the side of the coupler body 3 without an unhooking handle. The rotating component 2 has a second inclined surface 21, the inclination angle of which matches the inclination angle of the first inclined surface 11 of the fixing component 1. This allows it to cooperate with the fixing component 1 of the opposite coupler, limiting the unhooking handle 4 and preventing accidental movement of the unhooking handle during the unhooking process. It can be understood that the rotating component 2 and the fixing component 1 are respectively located on the same side of the two couplers, or on the left and right sides of the same coupler body 3, cooperating with the rotating component 2 and fixing component 1 on both sides of the opposite coupler.
[0058] The unhooking handle 4 is rotatably mounted on the coupler body 3 and is connected to the coupler body 3 by an elastic element 5. The unhooking handle 4 has an initial position and an unhooking position. When the two couplers need to be unhooked, the unhooking handle 4 needs to be manually pulled to the unhooking position so that the two couplers can be unhooked.
[0059] As attached Figure 1 - Appendix Figure 3 As shown, when the two coupled couplers need to be uncoupled, the rotating part 2 rotates to the position where it overlaps with the fixing part 1 of the opposite coupler. At this time, the second inclined surface 21 of the rotating part 2 itself is engaged with the first inclined surface 11 of the fixing part 1 on the opposite side.
[0060] When the uncoupling handle 4 of the coupler is pulled to the fully open position, the uncoupling handle 4 enters the interior of the rotating part 2 of the opposite coupler. The rotating part 2 of the opposite coupler limits the uncoupling handle 4, ensuring that the uncoupling handle 4 remains in the correct position during the uncoupling process. This prevents the uncoupling handle 4 from moving unexpectedly due to external force or human factors. At the same time, the rotating part 2 limits the uncoupling handle 4 during the uncoupling process, eliminating the need for operators to continuously manually fix the position of the uncoupling handle 4, thus reducing labor costs and safety risks during the uncoupling process.
[0061] As attached Figure 10 - Appendix Figure 12 As shown, when the two couplers are separated after uncoupling, the first inclined surface 11 and the second inclined surface 21 slide relative to each other, and the rotating part 2 is lifted by the fixed part 1. When the two couplers are separated to a certain distance, the limit on the uncoupling handle 4 is released. The uncoupling handle 4 is automatically reset under the action of the elastic part 5. Through the cooperation between the inclined surfaces, the rotating part 2 is automatically lifted during the coupler separation process to release the limit on the uncoupling handle 4, which improves the efficiency, convenience and automation of the uncoupling operation. At the same time, it further reduces manual intervention and reduces the operational risk.
[0062] In some embodiments of this utility model, a limiting block 41 is provided on the unhooking handle 4, and a corresponding limiting groove 22 is provided on the rotating component 2. When the unhooking handle 4 of the coupler is pulled to the fully open position, the limiting block 41 is engaged in the limiting groove 22. The cooperative use of the limiting block 41 and the limiting groove 22 further enhances the limiting effect of the rotating component 2 on the unhooking handle 4, ensuring that the unhooking handle 4 remains in the fully open position during the unhooking process. At the same time, the structure of the limiting block 41 and the limiting groove 22 is simple, reducing production costs and maintenance difficulty.
[0063] In some embodiments of this utility model, the limiting block 41 is disposed on the top end face of the unhooking handle 4, and the limiting groove 22 and the second inclined surface 21 are located on the same end face, so that when the rotating part 2 and the fixing part 1 are connected, the limiting block 41 can be accurately inserted into the limiting groove 22, thereby effectively limiting the unhooking handle 4.
[0064] In some embodiments of this utility model, the fixing member 1 and the rotating member 2 are respectively arranged on the left and right sides of the coupler connecting surface, so as to facilitate the connection with the rotating member 2 and the fixing member 1 of the coupler on the opposite side.
[0065] In some embodiments of this utility model, as shown in the appendix Figure 6 - Appendix Figure 9 As shown, the rotating part 2 and the hook body 3 of the coupler are rotatably connected by a rotating shaft 6.
[0066] Specifically, the rotating shaft 6 is fixedly installed on the coupler body 3; the rotating component 2 has a connecting hole 23, through which the rotating component 2 cooperates with the rotating shaft 6 to achieve a rotatable connection. The setting of the rotating shaft 6 enables the rotating component 2 to rotate flexibly and stably, ensuring that the rotation angle and position of the rotating component 2 during the uncoupling process can accurately cooperate and connect with the fixing component 1 of the opposite coupler.
[0067] In some embodiments of this utility model, the coupler includes a hook body 3, an inner cavity is provided inside the hook body 3, a hook tongue 7 is provided inside the inner cavity, one end of the unhooking handle 4 is provided in the inner cavity of the hook body, inserted into the hook tongue 7 and fixedly connected to the hook tongue 7 by a nut, and the other end extends out of the inner cavity of the hook body through a slot on the side wall of the hook body. The unhooking handle 4 can move along the extension direction of the slot to drive the hook tongue 7 to rotate.
[0068] In some embodiments of this utility model, an elastic element 5 is further provided in the inner cavity of the hook body. One end of the elastic element 5 is connected to the hook unhooking handle 4, and the other end is connected to the inner wall of the inner cavity of the hook body.
[0069] This mechanical transmission structure can effectively transmit the operating force of the unhooking handle 4 to the hook tongue 7, achieving precise and reliable unhooking control. The transmission process is more flexible and smooth, reducing friction and wear between components and improving the service life and operating performance of the coupler.
[0070] In some embodiments of this utility model, the coupler is a close-fitting coupler.
[0071] Some embodiments of the present invention further provide a coupler, including the above-described coupler uncoupling device.
[0072] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0073] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
