[0033] In some embodiments, the hoisting assembly 3 includes a hoisting rod 3-1 and two support sleeves 3-2.

[0034] Two support sleeves 3-2 are oppositely arranged on the vehicle body 4. In the embodiment, the support sleeves 3-2 are fixedly arranged on the vehicle body 4 by welding, so as to ensure firm connection.

[0035] The boom 3-1 is arranged in the two support sleeves 3-2 respectively, so as to support the boom 3-1 by the two support sleeves 3-2. In the embodiment, in order to facilitate the action of the boom 3-1 in the support sleeves 3-2 and facilitate installation, the diameter of the boom 3-1 is less than or equal to the diameter of the support sleeves 3-2.

[0037] In the embodiment, when the vehicle is running, the footrest part 2-1 is located at the first position, the boom 3-1 is operated in the support sleeves 3-2, the middle part of the boom 3-1 is arranged in the mounting part 2-2, the middle part of the boom 3-1 lifts the footrest part 2-1 through the mounting part 2-2, so as to increase the height of the footrest part 2-1, i.e. increase the distance between the footrest part 2-1 and the rail surface, so that the bottom of the footrest part 2-1 does not interfere with the lower limit, and the safety of the vehicle is ensured. When it is needed to get on or off the vehicle, the footrest part 2-1 is located at the second position, the boom 3-1 is operated in the support sleeves 3-2, the middle part of the boom 3-1 is separated from the mounting part 2-2, so as to operate the footrest part 2-1, and reduce the height of the footrest part 2-1, i.e. reduce the distance between the footrest part 2-1 and the rail surface, so as to facilitate getting on or off the vehicle.

[0038] Referring to Figure 2 In the embodiment, the boom 3-1 comprises a lifting part 3-11, two connecting parts 3-12 and two rotating parts 3-13.

[0039] The two connecting parts 3-12 are arranged at the two ends of the lifting part 3-11 respectively.

[0041] In the embodiment, when the footrest 2-1 is in the first position, the lifting part 3-11 is arranged in the mounting part 2-2, and the footrest 2-1 is lifted by the mounting part 2-2 through the lifting part 3-11, so as to increase the height of the footrest 2-1, i.e. increase the distance between the footrest 2-1 and the track surface, so that the bottom of the footrest 2-1 does not interfere with the lower limit, thereby ensuring the safety of the train operation. When the footrest 2-1 is in the second position, the rotating part 3-13 is operated, the rotating part 3-13 drives the lifting part to act through the connecting part 3-12, so as to separate the lifting part 3-11 from the mounting part 2-2, so as to operate the footrest 2-1 and reduce the height of the footrest 2-1, i.e. reduce the distance between the footrest 2-1 and the track surface, thereby facilitating the getting on and off the train.

[0042] In the embodiment, in order to facilitate the lifting part 3-11 to enter or separate from the mounting part 2-2, the cross-sectional shape of the mounting part 2-2 is hook-shaped, and the connecting part 3-12 is arranged at an angle with the rotating part 3-13 and the lifting part 3-11.

[0043] In the embodiment, when the footrest 2-1 is switched from the first position to the second position, the rotating part 3-13 is operated, the rotating part 3-13 is rotated in the supporting sleeve 3-2, the rotating part 3-13 drives the lifting part 3-11 to rotate through the connecting part 3-12, so as to change the position of the lifting part 3-11, so that the lifting part 3-11 separates from the mounting part 2-2, at the same time, the lifting part 3-11 is also staggered with the mounting part 2-2, and then the footrest 2-1 can be lowered, the height of the footrest 2-1 is reduced, i.e. the distance between the footrest 2-1 and the track surface is reduced, thereby facilitating the getting on and off the train. When the footrest 2-1 is switched from the second position to the first position, the rotating part 3-13 is operated, the rotating part 3-13 is reversely rotated in the supporting sleeve 3-2, the rotating part 3-13 drives the lifting part 3-11 to rotate through the connecting part 3-12, so as to change the position of the lifting part 3-11, so that the lifting part 3-11 is arranged in the mounting part 2-2, and the footrest 2-1 is lifted by the mounting part 2-2 through the lifting part 3-11, so as to increase the height of the footrest 2-1, i.e. increase the distance between the footrest 2-1 and the track surface, so that the bottom of the footrest 2-1 does not interfere with the lower limit, thereby ensuring the safety of the train operation.

[0044] In the embodiment, the angle between the connecting part 3-12 and the rotating part 3-13 can be an acute angle, an obtuse angle or a right angle, and the angle between the connecting part 3-12 and the lifting part 3-11 can be an acute angle, an obtuse angle or a right angle. In order to facilitate the operation of the rotating part 3-13 to drive the connecting part 3-12 to rotate, and also for easy manufacturing, preferably, the angle between the connecting part 3-12 and the rotating part 3-13 is a right angle, and the angle between the connecting part 3-12 and the lifting part 3-11 is a right angle.

[0045] In order to facilitate the operation of the rotating part 3-13 to drive the connecting part 3-12 to rotate, and also to facilitate the production, the rotating part 3-13 is parallel to the lifting part 3-11.

[0046] Of course, in other embodiments, the cross-sectional shape of the mounting part 2-2 is ring-shaped, and the connecting part 3-12 is horizontally arranged with the rotating part 3-13 and the lifting part 3-11. When the footrest part 2-1 is switched from the second position to the first position, one of the two rotating parts 3-13 sequentially passes through one of the two support sleeves 3-2 and the mounting part 2-2 into the other of the two support sleeves 3-2, until the other of the two rotating parts 3-13 enters one of the two support sleeves 3-2, that is, the boom 3-1 is sequentially inserted into one of the two support sleeves 3-2, the mounting part 2-2, and the other of the two support sleeves 3-2, at this time, the connecting part 3-12 drives the lifting part 3-11 into the mounting part 2-2, and the lifting part 3-11 lifts the footrest part 2-1 through the mounting part 2-2 to increase the height of the footrest part 2-1, that is, to increase the distance between the footrest part 2-1 and the track surface, so that the bottom of the footrest part 2-1 does not interfere with the lower limit, ensuring the safety of the car. When the footrest part 2-1 is switched from the first position to the second position, pull one of the rotating parts 3-13, and the rotating part 3-13 pulls the lifting part 3-11 through one of the connecting parts 3-12 to pull the lifting part 3-11 out of the mounting part 2-2, at the same time, the other of the connecting parts 3-12 pulls the other of the rotating parts 3-13 to separate the two rotating parts 3-13 from the two support sleeves 3-2, so that the lifting part 3-11 is separated from the mounting part 2-2, that is, the boom 3-1 is sequentially pulled out of one of the two support sleeves 3-2, the mounting part 2-2, and the other of the two support sleeves 3-2, and then the footrest part 2-1 can be lowered to reduce the height of the footrest part 2-1, that is, to reduce the distance between the footrest part 2-1 and the track surface, facilitating boarding and alighting. However, when the boom 3-1 is separated from the vehicle body 4 and the mounting part 2-2, the boom 3-1 is easy to lose, and when the boom 3-1 is pulled, due to the gravity of the footrest part 2-1, a large force is required to pull, which is not convenient to operate, therefore, preferably, the cross-sectional shape of the mounting part 2-2 is hook-shaped, and the connecting part 3-12 is arranged at an angle with the rotating part 3-13 and the lifting part 3-11.

[0047] In this embodiment, in order to facilitate the operation of the boom 3-1 to make the boom 3-1 enter the mounting part 2-2 or separate from the mounting part 2-2, one end of the boom 3-1 is provided with a handle, and the boom 3-1 is operated by holding the handle 3-2 by hand.

[0048] In the prior art, when the vehicle is running, the vehicle body 4 will vibrate up and down, which will cause the footrest 2 to jump up, causing the lifting assembly 3 to rotate and separate from the mounting portion 2-2, causing the footrest 2 to fall, and causing a safety accident of the vehicle. In some embodiments, in order to ensure the stability of the footrest 2 in the first position and ensure the safety of the vehicle, the footrest 2 is provided with anti-jumping platforms 5 on both sides, and the lifting assembly 3 is rotatably provided with a stopper 6. When the footrest portion 2-1 is in the first position, the stopper 6 abuts against the anti-jumping platform 5, and when the footrest portion 2-1 is in the second position, the stopper 6 is separated from the anti-jumping platform 5. In this embodiment, in order to facilitate installation, the two anti-jumping platforms 5 are respectively arranged on both sides of the bottom of the footrest portion 2-1.

[0049] In this embodiment, when the footrest portion 2-1 is in the first position, the stopper 6 abuts against the anti-jumping platform 5, and the anti-jumping platform 5 is locked by the stopper 6, so as to prevent the footrest 2 from jumping up by the anti-jumping platform 5, ensure the stability of the footrest 2 in the first position, and ensure the safety of the vehicle. When the footrest portion 2-1 is switched from the first position to the second position, the stopper 6 is rotated on the lifting rod 3-1 of the lifting assembly 3, so that the stopper 6 is separated from the anti-jumping platform 5, so that the footrest portion 2-1 can be lowered.

[0050] In this embodiment, when the footrest portion 2-1 is in the first position, in order to prevent the stopper 6 from being separated from the anti-jumping platform 5, the anti-jumping platform 5 is provided with a first limiting piece 7 on the end face facing the vehicle body 4, and the stopper 6 is blocked by the first limiting piece 7 to avoid the stopper 6 from being separated from the anti-jumping platform 5.

[0051] In some embodiments, in order to facilitate the installation of the footrest 2, a through slot with an opening is formed on the support 1, and the footrest portion 2-1 is arranged in the through slot. The footrest portion 2-1 can be placed into the through slot through the opening, and the footrest portion 2-1 can move up and down in the through slot.

[0052] In this embodiment, in order to avoid the footrest 2 from falling out of the through slot, the footrest further comprises a second limiting piece 8 for closing the opening, and the second limiting piece 8 is arranged on the support 1. The footrest 2 is blocked by the second limiting piece 8 to ensure that the footrest 2 can only move in the up-down direction.

[0053] In this embodiment, in order to ensure that the second limiting piece 8 can completely block the footrest 2, the length of the second limiting piece 8 is greater than or equal to the length of the through slot.

[0054] In this embodiment, in order to ensure the stability of the installation of the second limiting piece 8, the second limiting piece 8 can be connected with the vehicle body 4 by welding. Specifically, the cross-sectional shape of the second limiting piece 8 can be a "Fang" character shape, so as to facilitate the connection of the second limiting piece 8 with the vehicle body 4.

[0055] In the embodiment, in order to ensure that the support 1 can support the support part 2-3, the length of the support part 2-3 is greater than the length of the through slot, so that the support part 2-3 can be in contact with the support frame 1 when the footrest part 2-1 is in the second position, and the footrest part 2-1 is prevented from falling off the through slot.

[0056] Based on the same inventive concept, the present application also proposes a railway vehicle which adopts the footrest, the specific structure of which is referred to the above embodiments, and has all the beneficial effects brought by all the technical solutions of the above embodiments due to the adoption of all the technical solutions of the above embodiments, which will not be described one by one here.

[0057] Referring to Figure 3 In some embodiments, the railway vehicle comprises a vehicle body 4, and the support 1 is arranged on the vehicle body 4 to support the footrest through the vehicle body 4.

[0058] In some embodiments, the railway vehicle can be one or more of a flat car, an open car, a box car, and a tank car.

[0059] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all such modifications or equivalent replacements should be covered in the scope of the claims of the present application.
