DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0044] It should be noted that all directionality indications in the embodiments of the present application are only used to explain the relative positional relationship, motion condition and the like between components in a certain specific posture, and if the specific posture changes, the directionality indications also change accordingly.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0047] In the related art, there is a certain limiting need for goods, or the flat cars conveying goods such as vehicles are provided with end doors rotatably connected with the car bodies of the flat cars. The end doors are rotated relative to the car bodies of the flat cars to be vertically protruding relative to the car bodies, thereby playing a certain limiting role. The end doors are rotated relative to the car bodies of the flat cars to be horizontally supported on the car bodies, and the horizontally placed end doors can play a transition role between different car bodies of the flat cars, for unloading goods or for vehicles and other goods to pass through, etc. When the end doors are in the state of vertically protruding relative to the car bodies, a latch or a fastener is needed to position the end doors and the car bodies. The position of the latch or the fastener is usually located between the two car bodies, and manually operating the latch or the fastener to connect the end doors and the car bodies has certain danger and is not efficient, which affects the state changing efficiency of the end doors, and affects the goods transportation or loading and unloading, and the loading and unloading efficiency of the flat cars is affected, and there is a technical problem that the loading and unloading efficiency of the flat cars is not ideal. The embodiments of the present application provide a flat car which can at least solve the above technical problems to some extent.

[0048] The present application will be described below with reference to the accompanying drawings:

[0049] Figure 1Fig. 1 shows a structural schematic diagram of a flat car according to some embodiments or certain embodiments of the present application, Figure 2 Fig. 2 shows a schematic diagram of an end structure of a flat car according to some embodiments or certain embodiments of the present application, Figure 3 Fig. 3 shows a front view of an end of a flat car according to some embodiments or certain embodiments of the present application, referring to Figures 1 to 3 The embodiments of the present application provide a flat car, comprising:

[0050] A car body 1 is provided with two ends.

[0051] Two end doors 2 are opposite to each other and are respectively rotatably connected to the two ends 11 of the car body 1.

[0052] A positioning assembly 3 is provided with a transmission part 31 and a plug-in part 32, the transmission part 31 is rotatably connected with the end door 2 and extends to at least one side of the car body 1, the plug-in part 32 is drivingly connected to the transmission part 31, and the transmission part 31 is rotatable to the plug-in part 32 inserted into the car body 1 relative to the end door 2.

[0053] Two end doors 2 are opposite to each other and are rotatably connected to the two ends of the vehicle body 1. The end doors 2 can rotate relative to the vehicle body 1 to vertically protrude from the vehicle body 1, thereby limiting the goods on the vehicle body 1. The end doors 2 can also rotate relative to the vehicle body 1 to horizontally support on the vehicle body 1, thereby allowing the vehicle and other goods to pass. The flat car is also provided with a positioning assembly 3. The positioning assembly 3 is provided with a transmission part 31 and a plug-in part 32. The transmission part 31 of the positioning assembly 3 is rotatably connected to the end door 2, and the transmission part 31 extends to at least one side of the vehicle body 1. When the end door 2 needs to be positioned, for example, protrudes from the vehicle body 1, an operator can operate the transmission part 31 from one side or both sides of the vehicle body 1 to make the transmission part 31 rotate relative to the end door 2. The plug-in part 32 is drivingly connected to the transmission part 31. The plug-in part 32 can be driven by the transmission part 31 to be inserted into the vehicle body 1. The vehicle body 1 of the flat car has a certain space on both sides. The transmission part 31 extending to at least one side of the vehicle body 1 can have a relatively safe operating space, thereby improving the safety of the operator operating the transmission part 31. After the plug-in part 32 is plugged into the vehicle body 1, the plug-in part 32 is limited by the vehicle body 1. The plug-in part 32 and the transmission part 31 are in the same positioning assembly 3, and there is a force transmission between the plug-in part 32 and the transmission part 31. When the plug-in part 32 is limited by the vehicle body 1, the transmission part 31 will also be limited to a certain extent. The limited transmission part 31 can limit and support the end door 2 to a certain extent, so that the position of the end door 2 relative to the vehicle body 1 can be fixed to a certain extent. The plug-in part 32 can move with the rotation of the transmission part 31 to be inserted into the vehicle body 1. Therefore, the plug-in part 32 can also move with the rotation of the transmission part 31 to be separated from the vehicle body 1. When the end door 2 needs to be rotated relative to the vehicle body 1, an operator can also manually operate the transmission part 31 from one side of the vehicle body 1 to separate the plug-in part 32 from the vehicle body 1. The operator can operate the transmission part 31 near the flat car to complete the positioning or release of the end door 2, and then change the state of the end door 2. The operation is simple and safe, which can improve the time for changing the state of the end door 2 to facilitate the movement of the goods, improve the efficiency of loading and unloading the goods by the flat car, and solve the technical problem that the loading and unloading efficiency of the flat car is not ideal to a certain extent.

[0054] It should be noted that the positioning assembly 3 is connected to one end door 2 of the vehicle body 1, which can reduce the time required for positioning and state adjustment of the end door 2, thereby facilitating the movement of the goods by the flat car and improving the movement efficiency of the goods to a certain extent. When the plug-in part 32 is separated from the vehicle body 1, the end door 2 can freely rotate relative to the vehicle body 1, and the rotation of the end door 2 relative to the vehicle body 1 can be driven by a manual or driving mechanism. In this application, the two ends of the vehicle body 1 are the two ends in the length direction of the vehicle body 1, and at least one side of the vehicle body 1 is at least one side in the width direction of the vehicle body 1.

[0055] In some or certain embodiments, the transmission part 31 is provided with two ends extending to both sides of the vehicle body 1, respectively. The two ends of the transmission part 31 are spaced apart from the end door 2.

[0056] The transmission part 31 is provided with two ends respectively extending to the two sides of the vehicle body 1, and both ends are spaced from the end door 2 to provide an operating space for the operator. The operator can operate the transmission part 31 on either side of the flat car, effectively reducing the time to complete the positioning of the end door 2, reducing the time required for the state change of the end door 2, and facilitating the improvement of the loading and unloading efficiency of the flat car for goods.

[0057] In some or certain embodiments, the positioning assembly 3 comprises:

[0058] The handle 33 is connected with the peripheral wall of one end of the transmission part 31.

[0059] The positioning assembly 3 further comprises a handle 33 connected with the peripheral wall of one end of the transmission part 31, and the operator can operate the transmission part 31 through the handle 33, which is convenient for controlling the rotation of the transmission part 31 and quickly completing the positioning or loosening of the end door 2, thereby improving the loading and unloading efficiency of the flat car for goods.

[0060] In some or certain embodiments, the positioning assembly 3 can comprise two handles 33, and the two handles are respectively connected with the two ends of the transmission part 31. This is convenient for operation and improves the loading and unloading efficiency of the flat car for goods.

[0061] In some or certain embodiments, the flat car can also comprise two positioning assemblies 3, and the transmission parts 31 of the two positioning assemblies 3 are respectively rotationally connected with the two end doors 2. The state of the two end doors 2 can be controlled, and when loading vehicles or other goods, the two end doors 2 can be placed flat to allow vehicles to pass through.

[0062] In some or certain embodiments, the two end doors 2 can be located between the two positioning assemblies 3, and the insertion parts 32 of the two positioning assemblies 3 can be respectively used to connect with the two ends of the vehicle body 1. This can effectively reduce the possibility of interference. The positioning assembly 3 can also be arranged on one side of the vehicle body 1, and the insertion part 32 can also be inserted into one side of the vehicle body 1. Connection and fixation can also be achieved.

[0063] In some or certain embodiments, the positioning assembly 3 can comprise:

[0064] The rotation structure is configured as the transmission part 31.

[0065] The insertion part is connected with the peripheral wall of the rotation structure, and the side away from the rotation structure is configured as the insertion part 32.

[0066] The rotation structure is configured as the transmission part 31, and the structure of the rotation structure facilitates the rotational cooperation with the end door 2. The insertion part is connected with the peripheral wall of the rotation structure, and the side away from the rotation structure is configured as the insertion part 32. This can make there be a certain distance between the insertion part 32 and the rotation structure. When the rotation structure rotates relative to the end door 2, the insertion part 32 can have a relatively large linear speed, which is convenient for the rapid movement of the insertion part 32 to connect with the vehicle body 1.

[0067] It should be noted that the rotary structure is configured as the transmission part 31, and the axial two ends of the rotary structure are respectively configured as the two ends of the transmission part 31.

[0068] In some or certain embodiments, one end of the rotary structure can also be rotatably inserted into the end door 2, and the other end of the rotary structure can extend out of the end door 2 and extend to one side of the vehicle body 1. This can also facilitate the operation of the operator.

[0069] In some or certain embodiments, the end door 2 can be provided with a protrusion 24 through which the rotary structure passes, and the rotary structure can pass through the protrusion 24 and rotate around its own axis, and the two ends of the rotary structure extend to the two sides of the vehicle body 1, respectively. This facilitates the assembly of the rotary structure and the end door 2, and also facilitates the operation of the two ends of the rotary structure to control the position of the insertion part 32.

[0070] In some or certain embodiments, the positioning assembly 3 can include at least two insertion parts, and the at least two insertion parts are spaced apart along the axial direction of the rotary structure.

[0071] The at least two insertion parts are spaced apart along the axial direction of the rotary structure, and each insertion part is connected to the peripheral wall of the rotary structure, and the insertion part is provided with the insertion part 32, so that the at least two insertion parts can be moved into the vehicle body 1 along with the rotation of the rotary structure, thereby enhancing the supporting and positioning effect of the end door 2.

[0072] In some or certain embodiments, the insertion part can be plate-shaped, block-shaped, or rod-shaped, and the vehicle body 1 can be provided with a hole or a slot corresponding to the insertion part 32 of the insertion part. When the rotary structure is rotated by a certain angle relative to the end door 2, the insertion part moves together with the rotary structure, and the insertion part 32 of the insertion part can be rotated to be inserted into the corresponding hole or slot of the vehicle body 1, thereby completing the positioning of the insertion part 32 and the rotary structure.

[0073] In some or certain embodiments, the vehicle body 1 is provided with a positioning slot 12 and a limiting part 4 inserted into the positioning slot 12, the insertion part 32 is provided with a waist-shaped hole 322 movably sleeved on the limiting part 4, and the insertion part 32 is used to move into or separate from the positioning slot 12 along with the rotation of the transmission part 31.

[0074] The positioning groove 12 provided on the vehicle body 1 is used for inserting and matching the inserting part 32. The limiting part 4 is arranged in the positioning groove 12, and the inserting part 32 is movably sleeved on the limiting part 4. When the transmission part 31 rotates relative to the end door 2, the transmission part 31 can drive the inserting part 32 to move. The inserting part 32 can be inserted into the positioning groove 12 or separated from the positioning groove 12. However, the inserting part 32 is movably sleeved on the limiting part 4 in the positioning groove 12. Even if the inserting part 32 is separated from the positioning groove 12, the limiting part 4 can limit the inserting part 32 to prevent the inserting part 32 from falling off. Subsequently, when the position of the transmission part 31 is adjusted, the inserting part 32 can also be driven to move and be inserted into the positioning groove 12.

[0075] It should be noted that the inserting part 32 is inserted into the positioning groove 12, and the inserting part 32 and the groove bottom or the groove wall of the positioning groove 12 are in abutment or other interaction. The inserting part 32 is separated from the positioning groove 12, which means that the inserting part 32 is not in contact with the groove bottom of the positioning groove 12.

[0076] For the convenience of understanding, the following is provided Figure 4 With Figure 5 , Figure 4 Fig. 1 shows a schematic diagram of a use state of a positioning assembly in some embodiments or certain embodiments of the application, Figure 5 Fig. 2 shows another schematic diagram of a use state of a positioning assembly in some embodiments or certain embodiments of the application, Figure 4 In Fig. 1, the inserting part 32 is inserted into the positioning groove 12 of the vehicle body 1, and the end door 2 is in a vertical state, Figure 5 In Fig. 2, the inserting part 32 is separated from the positioning groove 12 of the vehicle body 1, and the end door 2 is in a horizontal state.

[0077] In some or certain embodiments, the limiting part 4 can be a pin or a column, and the limiting part 4 can be connected with the vehicle body 1 and inserted into or located in the positioning groove 12. The inserting part 32 can be provided with a hole corresponding to the limiting part 4, and the hole diameter of the hole corresponding to the limiting part 4 is greater than the limiting part 4. The limiting part 4 can limit the inserting part 32.

[0078] In some or certain embodiments, the vehicle body 1 is provided with a protruding matching part 13, and the positioning groove 12 is arranged in the matching part 13. The limiting part 4 is detachably connected with the matching part 13.

[0079] The vehicle body 1 is provided with a protruding matching part 13, and the positioning groove 12 is arranged on the matching part 13, so as to facilitate the matching with the inserting part 32. The limiting part 4 is detachably connected with the matching part 13, so as to facilitate the disassembly and maintenance of the positioning assembly 3.

[0080] In some or certain embodiments, the vehicle body 1 can be provided with the matching part 13 at both ends, and the matching part 13 at each end of the vehicle body 1 can be matched with the corresponding inserting part 32. The overall positioning and supporting effect is improved.

[0081] Figure 6 The structure of a positioning assembly in some embodiments or certain embodiments of the application is shown with reference to Figure 6 In some or certain embodiments, the vehicle body 1 is provided with a positioning slot 12 and a limiting piece 4 inserted into the positioning slot 12, and the positioning assembly 3 comprises:

[0082] The rotating structure is configured as a transmission part 31.

[0083] The transition piece 34 is connected with the peripheral wall of the rotating structure, and the plug-in part 32 is movably sleeved on the transition piece 34 and the limiting piece 4, and the plug-in part 32 is used to move to be inserted into or separated from the positioning slot 12 with the rotation of the rotating structure.

[0084] The positioning slot 12 of the vehicle body 1 can be inserted into the plug-in part 32. The rotating structure in the positioning assembly 3 is used to realize the cooperation with the end door 2, and the transition piece 34 is provided to facilitate the connection and movement of the plug-in part 32. The plug-in part 32 is movably sleeved on the transition piece 34 and the limiting piece 4. When the rotating structure rotates, there can be a certain adjustment space between the transition piece 34 and the plug-in part 32. After the transition piece 34 rotates to a certain extent, it can abut against the plug-in part 32. The transition piece 34 continues to rotate with the transmission part 31 to drive the plug-in part 32 to move to be separated from the positioning slot 12, and at the same time, the plug-in part 32 can be limited by the limiting piece 4, so that the plug-in part 32 will not fall off. When it is needed to re-insert the plug-in part 32 into the positioning slot 12, the transmission part 31 is reversely rotated to drive the plug-in part 32 to be re-inserted into the positioning slot 12.

[0085] It should be noted that when the limiting piece 4 is inserted into the positioning slot 12 and the plug-in part 32 is movably sleeved on the limiting piece 4, the positioning slot 12 can be provided as a U-shaped slot or a special-shaped slot with a slot opening inclined relative to the end 11 of the vehicle body 1. Correspondingly, the limiting piece 4 can be arranged at the opening or edge of the positioning slot 12, and then the plug-in part 32 can be movably sleeved on the limiting piece 4. The plug-in part 32 can be separated from the positioning slot 12 while being sleeved on the limiting piece 4.

[0086] In some or certain embodiments, the plug-in part 32 is provided with a movable hole 321 and a waist-shaped hole 322 which are spaced apart from each other and whose axes extend along the axial direction of the rotating structure. The movable hole 321 is movably sleeved on the transition piece 34, and the waist-shaped hole 322 is movably sleeved on the limiting piece 4.

[0087] The movable hole 321 of the plug-in part 32 is spaced from the waist-shaped hole 322, and both axially extend along the axial direction of the rotary structure. The movable hole 321 movably sheaths the transition piece 34, and the waist-shaped hole 322 movably sheaths the limiting piece 4. This arrangement can reduce interference, and the transition piece 34 and the movable hole 321 can have a certain degree of freedom. The transition piece 34 can rotate to a certain extent and then drive the plug-in part 32 to move. The overall stability is also high.
