[0031] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.

[0033] In the related art, the flat car 10 includes a car body 1 and a ladder 2, and the ladder 2 is connected to the car body 1. However, the car body 1 is usually a steel structure. When the ladder 2 is unfolded or folded, the ladder 2 will be in rigid contact with the steel structure, which will cause damage to the paint on the surface of the car body 1 and the ladder 2.

[0034] To this end, the present application proposes a flat car 10 .

[0035] The flat car 10 according to the embodiment of the present application includes: a car body 1, a ladder 2 and a first buffer device 3.

[0036] like Figure 1 As shown, the vehicle body 1 has a carrying surface 11 for carrying goods, and the ladder 2 is rotatably mounted on one end of the carrying surface 11. The ladder 2 has an unfolded state and a stowed state. In the stowed state, Figure 1 and Figure 2 As shown, the ladder 2 is stored in the vehicle body 1 .

[0037] It is understandable that the cargo may be a motor vehicle or a container, etc., which is not limited here.

[0038] For example, when in the storage state, the ladder 2 can be rotated to the top of the vehicle body 1, that is, in the height direction of the flat car 10, at least part of the projection of the ladder 2 falls on the vehicle body 1. In this way, the space occupied by the ladder 2 in the length direction or width direction of the flat car 10 when in the storage state can be reduced, thereby reducing the impact on the length direction dimension or width direction dimension of the flat car 10.

[0039] In the expanded state, Figure 3 As shown, the ladder 2 is unfolded in the length direction of the flat car 10 and is suitable for overlapping with the ground.

[0040] As a result, cargo such as containers or motor vehicles can be transported to the load-bearing surface 11 via the ladder 2, thereby reducing the difficulty of loading and unloading cargo. In particular, motor vehicles can achieve self-wheel loading and unloading via the ladder 2, further reducing the difficulty of loading and unloading motor vehicles.

[0041] It should be noted that in the related art, the flat car 10 is usually not provided with a ladder 2, and the wheeled vehicles and crawler vehicles need to be hoisted or supported by a platform to achieve loading and unloading, which requires a high loading and unloading site. In the present application, by providing a ladder 2, the ladder 2 can be rotatably mounted on the vehicle body 1, so that when the wheeled vehicles and crawler vehicles need to be loaded and unloaded, the wheeled vehicles and crawler vehicles can climb to the bearing surface 11 through the ladder 2 or move to the ground by the ladder 2. In this way, the wheeled vehicles and crawler vehicles can achieve self-wheel loading and unloading through the ladder 2, further reducing the difficulty of loading and unloading motor vehicles.

[0042] At the same time, the ladder 2 of the present application can be rotatably installed on the vehicle body 1, so that the user can control the state of the ladder 2 according to needs, thereby meeting the user's usage needs.

[0043] The vehicle body 1 is provided with a first buffer device 3 , and the first buffer device 3 is configured to be in flexible contact with the ladder 2 in an unfolded state and / or a retracted state.

[0044] For example, the first buffer device 3 can be a structure that can achieve flexible contact, such as an elastic member 41 or a flexible member, which is not limited here. It can be understood that since the vehicle body 1 is usually a steel structure, by setting the first buffer device 3, when the ladder 2 is in the unfolded state, the first buffer device 3 is in flexible contact with the ladder 2, which can avoid the ladder 2 from being in rigid contact with the vehicle body 1 in the unfolded state, or when the ladder 2 is in the stored state, the first buffer device 3 is in flexible contact with the ladder 2, which can avoid the ladder 2 from being in rigid contact with the vehicle body 1 in the stored state, or when the ladder 2 is in the unfolded state and the stored state, the first buffer device 3 can be in flexible contact with the ladder 2, which can avoid the ladder 2 from being in rigid contact with the vehicle body 1 in the unfolded state and the stored state, that is, avoid the ladder 2 from being in rigid contact with the steel structure, thereby reducing the damage to the coating on the surface of the vehicle body 1, and is conducive to protecting the ladder 2, thereby reducing the damage to the ladder 2.

[0045] According to the flat car 10 of the embodiment of the present application, the car body 1 has a bearing surface 11 for carrying goods, and the ladder 2 is rotatably installed at one end of the bearing surface 11. The ladder 2 has an unfolded state and a stowed state. In the stowed state, the ladder 2 is stowed in the car body 1, and in the unfolded state, the ladder 2 is unfolded in the length direction of the flat car 10 and is suitable for overlapping with the ground; wherein, a first buffer device 3 is provided at the connection between the car body 1 and the ladder 2, and the first buffer device 3 is configured to flexibly contact with the ladder 2 in the unfolded state and / or the stowed state, so that when the ladder 2 is in the unfolded state and / or the stowed state, the car body 1 can flexibly contact with the ladder 2 through the first buffer device 3, thereby avoiding rigid contact between the ladder 2 and the steel structure, thereby reducing damage to the paint on the surface of the car body 1, and is beneficial to protecting the ladder 2, thereby reducing damage to the ladder 2.

[0046] In some embodiments, Figure 4 As shown, the first buffer device 3 includes a first buffer block 31 and a second buffer block 32. The first buffer block 31 is configured to be in flexible contact with the ladder 2 in the unfolded state, and the second buffer block 32 is configured to be in flexible contact with the ladder 2 in the stored state.

[0047] As a result, the ladder 2 can be flexibly in contact with the first buffer block 31 when in the unfolded state, and can be flexibly in contact with the second buffer block 32 when in the stowed state. In this way, the first buffer block 31 and the second buffer block 32 can achieve flexible contact with the ladder 2 when the ladder 2 is in different states, thereby avoiding rigid contact between the ladder 2 and the vehicle body 1 in the unfolded state and the stowed state, that is, avoiding rigid contact between the ladder 2 and the steel structure, thereby reducing damage to the paint on the surface of the vehicle body 1, and helping to protect the ladder 2, thereby reducing damage to the ladder 2.

[0048] The first buffer block 31 and the second buffer block 32 may both be rubber blocks, which can reduce the cost and installation difficulty of the first buffer block 31 and the second buffer block 32 .

[0049] In some embodiments, Figure 2 As shown, the vehicle body 1 is provided with a mounting seat 12, and the ladder 2 is rotatably connected to the mounting seat 12 via a rotating shaft 13. Figure 4 As shown, the first buffer block 31 and the second buffer block 32 are both mounted on the mounting seat 12 and are located on both sides of the ladder 2 in the circumferential direction of the rotating shaft 13 .

[0050] Thus, the ladder 2 can be rotatably connected to the mounting seat 12 via the rotating shaft 13, that is, the ladder 2 is rotatably connected to the vehicle body 1, thereby facilitating the switching of the ladder 2 between the unfolded state and the stowed state. Figure 4 As shown, the first buffer block 31 and the second buffer block 32 are both mounted on the mounting seat 12 and are located on both sides of the ladder 2 in the circumferential direction of the rotating shaft 13 .

[0051] It can be understood that the rotation direction of the ladder 2 is the circumferential direction of the rotating shaft 13. Therefore, the first buffer block 31 and the second buffer block 32 are arranged on both sides of the ladder 2 in the circumferential direction of the rotating shaft 13, so that the first buffer block 31 and the second buffer block 32 can be arranged on the rotation path of the ladder 2, so that the ladder 2 can flexibly contact with the first buffer block 31 when in the unfolded state, and the ladder 2 can flexibly contact with the second buffer block 32 when in the stowed state, thereby avoiding rigid contact between the ladder 2 and the vehicle body 1 in the unfolded state and the stowed state, that is, avoiding rigid contact between the ladder 2 and the steel structure, thereby reducing damage to the paint on the surface of the vehicle body 1, and is beneficial to protecting the ladder 2, thereby reducing damage to the ladder 2.

[0052] Meanwhile, the first buffer block 31 and the second buffer block 32 are both mounted on the mounting seat 12 to reduce the difficulty of disposing the first buffer block 31 and the second buffer block 32 .

[0053] In some embodiments, the mounting seat 12 is further provided with a rotating shaft 15, and the flat car 10 further includes a cylinder 6, which is rotatably mounted on the mounting seat 12 via the rotating shaft 15, and the cylinder 6 is used to drive the ladder 2 to switch between the unfolded state and the stowed state.

[0054] It should be noted that, in the related art, the ladder 2 is usually unfolded and folded by manual control, which has high operating intensity and poses a safety hazard. In the present application, by providing the cylinder 6, the ladder 2 can be switched between the unfolded state and the folded state through the cylinder 6, thereby reducing the difficulty of switching the ladder 2 between the unfolded state and the folded state. At the same time, the operation is simple and helps to reduce safety hazards.

[0055] In some embodiments, Figure 4 As shown, a bushing is provided at the connection between the rotating shaft 13 and the mounting seat 12 , and the bushing is sleeved on the rotating shaft 13 .

[0056] Therefore, the bushing can be provided to reduce the wear of the connection between the rotating shaft 13 and the mounting seat 12, thereby playing a role in protecting the rotating shaft 13 and the mounting seat 12.

[0057] In some embodiments, Figure 1 As shown, the flat car 10 also includes a second buffer device 4, which is rotatably mounted on the vehicle body 1, and is suitable for being elastically connected to the ladder 2, and the second buffer device 4 is used to apply an elastic preload force to the ladder 2 to rotate toward the storage state.

[0058] Therefore, by providing the second buffer device 4, when the ladder 2 is switched from the stowed state to the unfolded state, the second buffer device 4 can provide a certain damping force on the rotation of the ladder 2, thereby preventing the ladder 2 from rotating too fast and hitting the first buffer device 3 or the vehicle body 1, thereby preventing the ladder 2 from rigidly contacting the steel structure, thereby reducing damage to the paint on the surface of the vehicle body 1, and helping to protect the ladder 2, thereby reducing damage to the ladder 2.

[0059] In some embodiments, the mounting base 12 is provided with a connecting shaft 14, and the second buffer device 4 is rotatably connected to the mounting base 12 via the connecting shaft 14, so that the second buffer device 4 can rotate around the connecting shaft 14 to achieve synchronous rotation with the ladder 2, thereby ensuring that the second buffer device 4 can continuously apply an elastic preload force to the ladder 2 to rotate toward the stowed state during the process of the ladder 2 switching from the stowed state to the unfolded state.

[0060] In some embodiments, a connecting bushing 141 is provided at the connection between the connecting shaft 14 and the mounting seat 12, and the connecting bushing 141 is sleeved on the connecting shaft 14. In this way, the wear of the connection between the connecting shaft 14 and the mounting seat 12 can be reduced by setting the connecting bushing 141, thereby protecting the connecting shaft 14 and the mounting seat 12.

[0061] In some embodiments, Figure 5 As shown, the second buffer device 4 includes an elastic member 41 .

[0062] Thus, an elastic pre-tightening force can be applied to the ladder 2 to rotate toward the storage state through the elastic member 41. For example, the elastic member 41 can be a structure with elastic deformation ability such as a spring or a reed leaf, and the structure of the elastic member 41 is relatively simple, which is conducive to reducing the setting cost and difficulty of the second buffer device 4.

[0063] In some embodiments, Figure 5 As shown, the second buffer device 4 also includes a first mounting seat 42 and a second mounting seat 43 . The first mounting seat 42 is rotatably connected to the vehicle body 1 , the second mounting seat 43 is connected to the ladder 2 , and the elastic member 41 is connected between the first mounting seat 42 and the second mounting seat 43 .

[0064] Thus, the first mounting seat 42 can be used to achieve a rotatable connection with the vehicle body 1, and the second mounting seat 43 can be used to achieve a connection with the ladder 2, and the elastic member 41 is elastically connected between the first mounting seat 42 and the second mounting seat 43, so that the elastic member 41 can be elastically deformed between the first mounting seat 42 and the second mounting seat 43, thereby achieving elastic deformation between the vehicle body 1 and the ladder 2, and then applying an elastic preload force to the ladder 2 to rotate toward the storage state.

[0065] In some embodiments, Figure 3 As shown, the flat car 10 further includes: a reinforcement device 5, one end of which is connected to the car body 1 and the other end of which is suitable for being detachably connected to the ladder 2, and the reinforcement device 5 is configured to be connected to the ladder 2 in the storage state.

[0066] It can be understood that one end of the reinforcement device 5 is connected to the vehicle body 1 and the other end is suitable for being detachably connected to the ladder 2. In this way, when the ladder 2 is switched from the storage state to the deployed state, the other end of the reinforcement device 5 can be controlled to separate from the ladder 2, that is, the ladder 2 is unlocked. At this time, the ladder 2 can be switched from the storage state to the deployed state, and when the ladder 2 is in the storage state, the other end of the reinforcement device 5 can be controlled to be connected to the ladder 2, thereby locking the ladder 2.

[0067] Therefore, by setting the reinforcement device 5, it is convenient to connect with the ladder 2 when the ladder 2 is in the storage state, so as to limit the ladder 2 in the storage state, thereby ensuring the structural stability of the ladder 2 in the storage state, thereby reducing the possible shaking of the ladder 2 during the driving of the flat car 10.

[0068] In some embodiments, Figure 2 As shown, the ladder 2 has a transition surface 21. In the unfolded state, the transition surface 21 is suitable for connecting with the bearing surface 11, and as shown in FIG. Figure 6 As shown, the transition surface 21 is provided with an anti-slip strip 22 .

[0069] Therefore, when a vehicle or container moves from the transition surface 21 to the load-bearing surface 11, the anti-skid strips 22 can enhance the friction between the vehicle or container and the transition surface 21, that is, improve the grip of the vehicle or container, thereby playing an anti-skid role, thereby preventing the vehicle or container from sliding backwards, thereby improving the safety of loading vehicles or containers.

[0070] In some implementations, such as Figure 6 As shown, the anti-skid strip 22 can be an anti-skid plate with rubber protrusions, so that the friction of the rubber protrusions on the vehicle or container can be used to prevent skidding, thereby preventing the vehicle or container from sliding backwards, thereby improving the safety of loading the vehicle or container.

[0071] In some embodiments, Figure 6 As shown, an end of the ladder 2 away from the vehicle body 1 is provided with an anti-wear strip 23, and the anti-wear strip 23 is suitable for overlapping with the ground.

[0072] Therefore, by providing the anti-wear strip 23, the ladder 2 can be in the unfolded state. Figure 2 As shown, the end of the ladder 2 away from the vehicle body 1 can overlap with the ground through the anti-wear strip 23, so as to avoid the end of the ladder 2 away from the vehicle body 1 directly contacting the ground, thereby protecting the ladder 2. For example, the anti-wear plate is made of high-strength material, so that the service life of the ladder 2 can be increased. At the same time, it can avoid as much as possible the damage to the ground caused by the ladder 2 directly hitting the ground.

[0073] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0074] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.

[0075] Although the preferred embodiments of this specification have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of this specification.

[0076] Obviously, those skilled in the art can make various changes and modifications to this specification without departing from the spirit and scope of this specification.
