DETAILED DESCRIPTION

[0027] The technical solutions of the present disclosure will be described in detail below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

In addition, if the terms “first”, “second”, “third” appear, they are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present disclosure, it should be explained that, unless otherwise explicitly specified and limited, the terms such as "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0030] Referring to Figures 1 to 6 As shown in the drawings, the embodiment provides a stop device, which comprises a base 100 and a stop portion 200, the base 100 is used for being mounted on a bogie 500, the stop portion 200 is connected with the base 100, the upper surface of the stop portion 200 is a vertical stop surface 201, and the surface of the stop portion 200 which faces the inside of the bogie 500 is a swing stop surface 202.

[0031] The stop device provided by the embodiment can not only play a swing stop role, but also play a vertical stop role, thereby improving the safety during locomotive operation. In use, the base 100 is mounted on the bogie 500, the car body is mounted on the bogie 500, and the distance between the lower surface of the car body and the vertical stop surface 201 is ensured. When the locomotive passes through a hump, the car body can be effectively prevented from being vertically displaced too much at both ends, so that the car body components and the components on the bogie are prevented from being contacted. At the same time, the swing stop surface 202 can ensure that the locomotive passes through a curve more safely, so as to adapt to complex special lines and different operation lines, and ensure the safety of the locomotive operation.

[0032] In the embodiment, the bogie 500 has two oppositely arranged long side sides 501, and the area between the two long side sides is the inside of the bogie 500.

[0033] In one embodiment, the stop device further comprises an adjusting pad 300, which is located between the base 100 and the stop portion 200, so as to adjust the distance between the vertical stop surface 201 and the lower surface of the car body.

[0034] The number of adjusting pads 300 can be multiple, and the number of adjusting pads 300 can be selected according to needs, that is, one adjusting pad 300 can be used in actual use, or multiple adjusting pads 300 can be used.

[0035] Taking a high-power hydrogen fuel cell hybrid locomotive as an example, the high-power hydrogen fuel cell hybrid locomotive is mainly used for shunting and transfer in a depot, a vehicle depot, a marshalling yard and a discontinuous industrial and mining enterprise of electrification. The running line passes through a hump, the locomotive applies a traction force of 520 kN, passes through a straight track at a speed of 100 km / h, and the track irregularity is an American fourth level spectrum with a maximum vertical displacement of 24.2 mm. When the track irregularity of the hump passes through the American fourth level spectrum, the maximum vertical displacement is 32.5 mm. In order to ensure the safety distance between the car body parts and the parts on the bogie, a stop device is arranged at the four corners of the 500 end of the bogie, and the distance between the lower surface of the car body and the vertical stop surface 201 is 25 mm.

[0036] In one embodiment, the base 100 is provided with a limiting portion, and the stop portion 200 is provided with a limiting matching portion. The limiting matching portion matches with the limiting portion to decompose the impact force on the swing stop surface 202 when the car body turns.

[0037] The limiting matching portion matches with the limiting portion, and when the car body turns, the impact force on the swing stop surface 202 can be decomposed, so that a larger impact force can be borne.

[0038] In some embodiments, the limiting portion is a limiting groove 101, and the limiting matching portion is a protruding portion 203, which is limited in the limiting groove 101.

[0039] For example, referring to Figure 2 The limiting groove 101 is a trapezoidal groove, which is arranged on the base 100 and penetrates the upper and lower surfaces of the base 100. The width of the groove opening of the trapezoidal groove is greater than the width of the groove bottom. When installed, the groove opening of the trapezoidal groove faces away from the outside of the long side 501 of the bogie 500. Figure 3 The protruding portion 203 is a trapezoidal boss, and the gap between the outer surface of the trapezoidal boss and the groove wall and the groove bottom of the trapezoidal groove is arranged. The trapezoidal boss is integrally formed with the stop portion 200. Of course, the trapezoidal boss can also be welded with the stop portion 200.

[0040] When the car body turns, the cooperation of the trapezoidal boss and the trapezoidal groove can decompose the impact force on the swing stop surface 202 into a transverse force and a longitudinal force, so that a larger impact force can be borne.

[0041] It should be noted that the limiting groove 101 is not limited to the trapezoidal groove. For example, the limiting groove 101 can also be an arc-shaped groove or other grooves with curved walls. Correspondingly, the contour shape of the protruding portion 203 is adapted to the shape of the limiting groove 101.

[0042] In other embodiments, the limiting matching portion is a limiting groove 101, and the limiting portion is a protruding portion 203, which is limited in the limiting groove 101.

[0043] In one embodiment, referring to Figure 4 shown, in order to ensure that the base 100, the stop 200 and the adjusting pad 300 can be normally assembled, the adjusting pad 300 is provided with a avoiding slot 301 for the protruding part 203 to pass through; the adjusting pad 300 is used to adjust the distance between the vertical stop surface 201 and the lower surface of the vehicle body.

[0044] For example, the profile of the avoiding slot 301 is the same as that of the trapezoidal slot, which is convenient for processing. Of course, the profile of the avoiding slot 301 can also be different from that of the trapezoidal slot, as long as the protruding part 203 can pass through the avoiding slot 301 and be limited in the trapezoidal slot.

[0045] In one embodiment, the number of the adjusting pad 300 is multiple, and the thicknesses of the multiple adjusting pads 300 are different, or the thicknesses of at least two adjusting pads 300 are the same. Wherein, multiple refers to two or more than two.

[0046] For example, the thickness of the adjusting pad 300 can be set to multiple specifications, such as, but not limited to, 1mm, 2mm, 3mm, 5mm, 10mm, and a large range of adjustment can be achieved by combining adjusting pads 300 with different thicknesses.

[0047] For example, the number of the adjusting pad 300 is three, and the thicknesses of the three adjusting pads 300 can be different, or the same, or the thicknesses of two adjusting pads 300 are the same, and the thickness of the third adjusting pad 300 is different from that of the two adjusting pads 300.

[0048] In one embodiment, the stop 200 and the base 100 are connected through a connecting piece, so that the stop 200 and the base 100 are detachably connected, which is convenient for adding or removing the adjusting pad 300 as needed. For example, the connecting piece can be a bolt.

[0049] In one embodiment, referring to Figures 1 to 3 shown, the connecting piece is a bolt 400, the stop 200 is provided with an oblong hole 204, and the base 100 is provided with a threaded hole 102, and the bolt 400 passes through the oblong hole 204 and is connected with the threaded hole 102.

[0050] By providing the oblong hole 204 on the stop 200, assembly is facilitated. Specifically, the projection of the profile of the oblong hole 204 in the upper surface of the base 100 can cover the projection of the profile of the threaded hole 102 in the upper surface of the base 100. When the bolt 400 passes through the oblong hole 204 and is connected with the threaded hole 102, there is a gap between the bolt 400 and the inner wall of the oblong hole 204, which serves as an adjustment amount, avoiding the problem of being unable to assemble due to insufficient processing precision.

[0051] For example, the number of threaded holes 102 is two, and the two threaded holes 102 are respectively located on the two sides of the trapezoidal groove.

[0052] Referring to Figure 4 As shown, in order to facilitate the installation of the bolt 400, the adjusting pad 300 is provided with a through hole 302 corresponding to the position of the threaded hole 102, so that the bolt 400 can pass through. When the vehicle body turns, the cooperation of the trapezoidal boss and the trapezoidal groove can decompose the impact force received by the swing stop surface 202, so as to be able to withstand larger lateral force and longitudinal force, effectively preventing the bolt from being sheared.

[0053] Of course, the connecting piece is not limited to a bolt, and for example, the connecting piece can be a magnet or the like magnetic piece, and the stop portion 200 and the base 100 are connected by magnetic attraction.

[0054] In an embodiment, the materials of the base 100 and the stop portion 200 are both steel, for example, S355J2 steel plate, i.e., a European standard low alloy high strength structural steel plate, which has good welding performance and high strength.

[0055] Referring to Figure 5 and Figure 6 As shown, the embodiment also provides a bogie 500, which comprises the stop device provided by the embodiment.

[0056] For example, the number of stop devices is four, which are respectively placed near the four corners of the bogie 500. The two long side sides 501 of the bogie 500 are respectively and symmetrically provided with two stop devices, and the slot opening of the limiting groove 101 on the base 100 of the stop device on one long side side 501 is opposite to the slot opening of the limiting groove 101 on the base 100 of the stop device on the other long side side 501.

[0057] The bogie provided by the embodiment can not only play a swing stop role, but also play a vertical stop role, thereby improving the safety during locomotive operation. In use, the base 100 is installed on the bogie 500, the vehicle body is installed on the bogie 500, and the distance between the lower surface of the vehicle body and the vertical stop surface 201 is ensured. When the locomotive passes through a hump, the vertical displacement of the two ends of the vehicle body is effectively prevented from being too large, so that the collision between the components of the vehicle body and the components on the bogie is avoided. At the same time, the swing stop surface 202 can ensure that the locomotive passes through a curve more safely, so as to adapt to complex special lines and different operation lines, and ensure the safety of locomotive operation.

[0058] The locomotive also comprises the bogie 500 provided by the embodiment, and the distance between the vertical stop surface 201 and the lower surface of the car body is a set distance, so as to limit the vertical displacement of the car body; the lower surface of the car body is provided with a stop structure, which can be in contact with the swing stop surface 202 to limit the rotation angle of the car body.

[0059] The locomotive provided by the embodiment can play the roles of swing stop and vertical stop, and ensure the distance between the lower surface of the car body and the vertical stop surface 201, so as to effectively prevent the car body components from colliding with the components on the bogie due to the large vertical displacement of the two ends of the car body when the locomotive passes over the hump; meanwhile, the stop structure provided on the lower surface of the car body can be in contact with the swing stop surface 202 to prevent the rotation angle of the car body from being too large, so as to avoid the collision between the car body components and the components on the bogie, thereby ensuring the locomotive to pass through the curve more safely, adapting to the complex special line and different operation lines, and improving the safety during the operation of the locomotive.

[0060] It should be noted that the stop structure of the locomotive is a prior art, and its structure will not be described in detail, for example, the stop structure can be a stop block.

[0061] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, but not to limit them; although the present disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
