Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rail vehicle technology, and in particular relates to a coupler support device. Background Technology
[0002] The coupler and buffer system is a key component connecting the various cars in a train. Its main functions include transmitting longitudinal forces, absorbing energy, and allowing the cars to swing laterally and vertically. To ensure the coupler remains horizontal, traditional coupler and buffer systems typically have a vertical support device below the coupler. However, for some car models, due to the need for driver's cab comfort, the overall installation position of the coupler is biased towards the underside of the car, very close to the track. The limited installation space below the coupler makes traditional vertical support devices unsuitable.
[0003] Furthermore, because the coupler needs to be capable of overload protection so that the vehicle's anti-climb devices and energy-absorbing zones can function effectively upon impact, maximizing the safety of onboard equipment and personnel, the design must ensure that the crushing device can move freely backward. However, in existing technologies, placing the crushing device directly on the vertical support may affect the expansion function of the expansion tube, thereby reducing the energy absorption capacity of the crushing device.
[0004] Therefore, there is an urgent need for a coupler support device that does not affect the expansion function of the expansion tube and meets the space requirements of some vehicle models. Utility Model Content
[0005] The purpose of this utility model is to solve one of the above-mentioned technical problems and provide a coupler support device.

The first wear member is fixedly connected to the second connector, and the end face near the force transmission component matches the shape of the side wall of the force transmission component.
[0017] In some embodiments of this utility model, a second wear member is further included, which is fixed to the end face of the support arm near the force transmission component.
[0018] In some embodiments of this utility model, the connecting component includes a pivot connector and a transverse support. One end of the transverse support is rotatably connected to the hook body of the coupler via the pivot connector, and the other end is connected to the elastic support.

[0024] The beneficial effects of this utility model are as follows:
[0025] 1. This utility model places the elastic support part with a large installation space requirement in the support component above the coupler, and sets a vertical support part with a smaller installation space requirement below the coupler to cooperate with it to achieve vertical support of the coupler, which effectively saves the space below the coupler, thereby making the overall installation height of the coupler lower and adaptable to some specific vehicle models with limited installation space below the coupler.

[0044] The technical solution of this utility model will be described in detail below with reference to specific embodiments and the accompanying drawings.
[0045] As attached Figure 1 -Appendix Figure 3 As shown in the schematic embodiment of the coupler support device of the present invention, the coupler support device includes a force transmission component 1 and a support component 2.
[0046] The force transmission component 1 is either an energy-absorbing mechanism or a rigid connector. When the force transmission component 1 is an energy-absorbing mechanism, it is installed between the buffer device and the coupling system to absorb energy during a collision.
[0047] The support component 2 includes an elastic support portion 21 and a vertical support portion 22.
[0048] The elastic support part 21 is disposed above the force transmission component 1 and is rotatably connected to the mounting base 4 via the connecting component 23. The mounting base 4 is fixedly connected to the hook body of the coupler. The elastic support part 21 provides vertical elastic support force to the force transmission component 1.
[0049] A vertical support portion 22 is disposed below the force transmission assembly 1. Both ends of the vertical support portion 22 are connected to the elastic support portion 21 via support arms, and the chain-structure support arms are clamped on both sides of the force transmission assembly 1. The vertical support portion 22 is used to provide upward support force for the force transmission assembly 1.
[0050] It should be noted that in this embodiment, the elastic support 21 is rotatably connected to the mounting base 4 via the connecting component 23. The connecting component 23 provides upward support to the elastic support 21. The force transmission component 1 is situated on the vertical support 22 and is connected to the elastic support 21 via the bracket arm. Through the transmission of force between the components, the force generated by the compression of the elastic support 21 is achieved, thus realizing the vertical support of the coupler.
[0051] In the above illustrative embodiment, through the synergistic action of the elastic support 21 and the vertical support 22, a vertical support force is provided to the crushing device without affecting its expansion function and ensuring that the crushing device can absorb energy normally. This achieves both support for the coupler and accommodates the vertical and lateral swing of the coupler. The elastic support 21 is positioned above the crushing device to adapt to vehicle environments with limited installation space below the coupler. Furthermore, after the crushing device is assembled and connected to the support assembly 2, it can slide freely along the length of the coupler. Under significant impact, the coupler's breakage bolt 3 will break, allowing the crushing device to retract backward, achieving an overload function. This enables the anti-climb device and the energy-absorbing zone of the impacted vehicle to function effectively.
[0052] In some embodiments of this utility model, the elastic support 21 and the support arm and the vertical support 22 and the support arm are connected by a height adjustment component 24.
[0053] The height adjustment assembly 24 includes an adjustment connector 241 and a limiting member 242, wherein the adjustment connector 241 is specifically an adjustment bolt and the limiting member 242 is specifically an adjustment nut.
[0054] In the height adjustment assembly 24 located between the elastic support 21 and the support arm, the adjusting connector 241 passes through the elastic support 21 from top to bottom and is inserted into the connecting hole at the end of the support arm, where it is slidably connected to the support arm. Two limiting members 242 are connected to the adjusting connector 241 and are distributed between the elastic support 21 and the support arm, respectively contacting and connecting with the elastic support 21 and the support arm. These limiting members restrict the position of the elastic support 21 axially within the adjusting connector 241, and allow control of the vertical distance between the elastic support 21 and the support arm by adjusting the distance between the two adjusting connectors 241.
[0055] In the height adjustment assembly 24 located between the vertical support 22 and the support arm, the adjusting connector 241 passes through the vertical support 22 from bottom to top and is inserted into the connecting hole at the end of the support arm, where it is slidably connected to the support arm. Two limiting members 242 are connected to the adjusting connector 241 and are distributed between the vertical support 22 and the support arm, respectively contacting and connecting with the vertical support 22 and the support arm. These limiting members restrict the position of the vertical support 22 axially along the adjusting connector 241, and the vertical distance between the vertical support 22 and the support arm can be controlled by adjusting the distance between the two adjusting connectors 241.
[0056] The vertical height of the elastic support part 21 and the vertical support part 22 can be flexibly adjusted by the height adjustment components 24 at both ends of the support arm, so that the support component 2 provided by this utility model can be applied to different coupler models and support requirements under different working conditions, and has good versatility.
[0057] When the coupler tilts down or up, the compression of the elastic support member 212 in the elastic support part 21 can be changed by adjusting the distance between the limiting members 242, thereby adjusting the height of the coupler.
[0058] In this embodiment, the elastic support 21 is connected to the support arm and the vertical support 22 is connected to the support arm through a height adjustment assembly 24. When adjusting the height, the upper bolts and nuts can be adjusted, as can the lower bolts and nuts, which improves the convenience of operation.
[0059] In some embodiments of this utility model, the elastic support portion 21 includes a first connector 211 and an elastic support portion 212.
[0060] The first connector 211 is a plate-shaped structure, with both ends connected to the support arm. The elastic support 212 is a cylindrical rubber support, disposed between the first connector 211 and the force transmission assembly 1, with its top end face connected to the first connector 211.
[0061] In some embodiments of this utility model, the first connector 211 and the elastic support 212 are designed as a single unit.
[0062] In some embodiments of this utility model, in order to reduce frictional loss between the support component 2 and the force transmission component 1 and extend the service life of the device, the elastic support part 21 further includes a support slide plate 213. The support slide plate 213 is disposed between the elastic support member 212 and the force transmission component 1, and its two ends in the length direction are recessed inward and engaged with the support arms at both ends, so that the support slide plate 213 can slide vertically along the support arms.
[0063] In some embodiments of this utility model, the vertical support portion 22 includes a second connector 221 and a first wear member 222. The second connector 221 is a plate-shaped structure with both ends connected to the support arm. The first wear member 222 is a wear support, fixedly connected to the second connector 221, and its end face near the force transmission component 1 is in contact with the force transmission component 1 and matches the shape of the side wall of the force transmission component 1, thereby reducing frictional loss between the support component 2 and the force transmission component 1.
[0064] In some embodiments of this utility model, a second wear member 25 is further included. The second wear member 25 is fixed to the end face of the support arm near the force transmission component 1 by bolts, so as to reduce the frictional loss between the support component 2 and the force transmission component 1.
[0065] When the coupler needs to swing left and right in the horizontal direction, the force transmission assembly 1 or the support arm can be pushed to make the coupler swing horizontally. When the coupler swings horizontally, the side wall of the force transmission assembly 1 contacts the second wear part 25, which in turn drives the support arm and the elastic support part 21 to swing, thereby enabling the connecting assembly 23 to rotate.
[0066] In some embodiments of this utility model, the connecting component 23 includes a pivot connector 231241 and a transverse support 232. One end of the transverse support 232 is rotatably connected to the mounting base 4 of the coupler body via the pivot connector 231241, and the other end extends between the elastic support 212 and the support slide plate 213 of the elastic support portion 21. The plate surface is fixedly connected to the support slide plate 213 by bolts and is in contact with the elastic support 212.
[0067] In some embodiments of this invention, the energy-absorbing mechanism is a buffer or a crushing device.
[0068] In some embodiments of this utility model, when the energy absorption mechanism is a crushing device, the crushing device includes an expansion tube 12, a guide rod 11, and a support sleeve 13.
[0069] The guide rod 11 passes through the expansion tube 12, and one end is connected to the expansion tube 12.
[0070] The support sleeve 13 is a cylindrical structure that can bear the weight of the through passage, the coupler and the crushing device in the vertical direction. One end of it is connected to the guide rod 11, and the support assembly 2 is supported on the upper and lower sides of the support sleeve 13.
[0071] In some embodiments of this utility model, the force transmission component 1 further includes a pull ring 14, one end of which is fixedly connected to the guide rod 11, and the other end is connected to the mounting base 4.
[0072] In some embodiments of this invention, the end of the guide rod 11 connected to the expansion tube 12 is provided with a stepped structure, including a first stepped portion located on the inner side and a second stepped portion located on the outer side. The guide rod 11 is assembled with the expansion tube 12 by pressing through the first stepped portion, and is welded to the support sleeve 13 through the second stepped portion.
[0073] In some embodiments of this utility model, the guide rod 11 is further processed with a third step protruding from the rod body, which is used to limit the support sleeve 13.
[0074] In some embodiments of this utility model, the guide rod 11, the support sleeve 13, and the pull ring 14 are processed into one piece using welding technology, and the whole structure is simple and practical.
[0075] In some embodiments of this utility model, the inner diameter of the support sleeve 13 is smaller than the outer diameter of the expansion tube 12 when it expands, so as to avoid affecting the expansion of the expansion tube 12 and the energy absorption of the crushing device.
[0076] In some embodiments of this utility model, a pull-off bolt 3 is further included, which is fixed on the mounting base 4. When the coupler is subjected to a large impact force, the pull-off bolt 3 will break and the force transmission component 1 can move backward as a whole to realize the overload function, thereby enabling the anti-climb device and the energy absorption zone of the vehicle body to function.
[0077] 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.
[0078] 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.
