For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0055] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0056] As Figures 1 to 6 shown, this embodiment provides a folding device for a freight car carriage, including a carriage top plate 1, a carriage bottom plate 2, folding plates 3, a transmission mechanism 4, and an opening and closing mechanism 5. Guide rails 6 are provided on both the carriage top plate 1 and the carriage bottom plate 2, and graphite chutes 61 are provided inside the guide rails 6; a plurality of folding plates 3 are arranged between the carriage top plate 1 and the carriage bottom plate 2 and are located on the side of the carriage. The folding plates 3 have an extended state and a folded state; the transmission mechanism 4 is arranged on the folding plates 3, and the transmission mechanism 4 is adapted to slide in the graphite chutes 61; the opening and closing mechanism 5 is arranged between adjacent folding plates 3 and is connected to the adjacent folding plates 3. The opening and closing mechanism 5 is adapted to fold the folding plates 3; under the action of an external force, the carriage has an open state in which the folding plates 3 are folded and a closed state in which the folding plates 3 are extended.

[0057] In the embodiment of the present utility model, when it is necessary to load and unload the boxed cigarettes, first push the folding plate 3 to drive the transmission mechanism 4 to slide in the graphite chute 61. At the same time, the opening and closing mechanism 5 performs a folding and closing operation, causing multiple folding plates 3 to fold and overlap, thereby opening the carriage. Then, use a forklift to load and unload the boxed cigarettes. After the boxed cigarettes are assembled, pull the folding plate 3 to unfold multiple folding plates 3, close the carriage, and complete the loading and unloading of the boxed cigarettes.

[0058] Most of the existing freight carriages are provided with a rear door, and both side walls of the carriage are welded and connected. The side walls of the carriage are fixed structures and cannot move, and the operation space of the rear door is limited, which leads to a longer loading and unloading time of the boxed cigarettes and reduces the loading and unloading efficiency of the boxed cigarettes. In the embodiment of the present utility model, by setting the transmission mechanism 4 and the opening and closing mechanism 5, a plurality of the folding plates 3 can be installed on the side of the carriage. The folding plates 3 perform opening and closing operations under the action of the transmission mechanism 4 and the opening and closing mechanism 5, thereby loading and unloading the boxed cigarettes and improving the loading and unloading efficiency of the boxed cigarettes.

[0059] Specifically, the transmission mechanism 4 includes a support rod 41 and a bearing 42. The support rod 41 is arranged on the folding plate 3; the bearing 42 is arranged in the graphite chute 61 and is connected to the support rod 41, and the bearing 42 slides in the graphite chute 61. By pushing the folding plate 3, the bearing 42 slides in the graphite chute 61, thereby performing an opening and closing operation on the carriage. In addition, in this embodiment, the graphite chute 61 is provided, which can make the friction force of the bearing 42 sliding in the graphite chute 61 smaller, thereby reducing the friction loss.

[0060] Furthermore, the diameter of the support rod 41 is smaller than the width of the guide rail 6, and the gap between the two is set to 5 mm. In the embodiment of the present utility model, by making the diameter of the support rod 41 5 mm smaller than the width of the guide rail 6, it can be avoided that the gap between the two is too large, resulting in unstable sliding of the folding plate 3, and at the same time, it can also be avoided that the gap between the two is too small, resulting in unsmooth sliding of the folding plate 3.

[0061] Specifically, as Figure 3 shown, the opening and closing mechanism 5 includes a connecting page assembly 51 and a folding assembly 52. The connecting page assembly 51 is detachably connected to the folding plate 3; the folding assembly 52 is arranged on the connecting page assembly 51, and the folding assembly 52 is adapted to open and close the connecting page assembly 51. The connecting page assembly 51 drives the folding plate 3 to fold and unfold under the rotational action of the folding assembly 52.

[0062] Further, the connection page assembly 51 includes a first connection page 511 and a second connection page 512. The first connection page 511 is installed on the folding plate 3; the second connection page 512 is installed on another folding plate 3, and the second connection page 512 is adapted to approach and move away from the first connection page 511, so that two adjacent folding plates 3 can be folded and extended with respect to each other.

[0063] Further, the first connection page 511 and the second connection page 512 are both provided with threaded holes 513, and fastening bolts pass through the threaded holes 513 and are threadedly connected to the folding plate 3. In addition, a sealing strip is provided between multiple folding plates 3, through which the carriage can be sealed, and at the same time, friction between the folding plates 3 can be avoided. When the carriage needs to be opened, the folding plate 3 is pushed, the bearing 42 slides in the graphite chute 61, and at the same time, the first connection page 511 and the second connection page 512 approach each other, driving multiple folding plates 3 to stack up, and the carriage is opened. Similarly, when the carriage is closed, the above process is operated in reverse.

[0064] Further, as Figure 5 and Figure 6 shown, the folding assembly 52 includes a hinge tube 521, a connecting tube 522, a conveying screw 523, a damping screw 524, and a fixing member 525. The hinge tube 521 is connected to the first connection page 511; the connecting tube 522 is connected to the second connection page 512, and the connecting tube 522 is connected to the hinge tube 521; a pair of conveying screws 523 are arranged in the connecting tube 522 and are respectively connected to the connecting tube 522 through a connecting member 526, and the conveying screw 523 is adapted to rotate synchronously; a pair of damping screws 524 are threadedly connected to the conveying screw 523, and the damping screw 524 is adapted to adjust the opening and closing degree of the connection page assembly 51; one end of the fixing member 525 is respectively connected to a pair of the damping screws 524, and the other end is connected to the connecting tube 522; under the action of an external force, the conveying screw 523 rotates around the damping screw 524, driving the first connection page 511 and the second connection page 512 to fold and coincide, so that the carriage is opened. In the embodiment of the present invention, by providing the damping screw 524, the conveying screw 523 can be rotated around the damping screw 524, thereby adjusting the opening and closing degree of the first connection page 511 and the second connection page 512, making the opening and closing of the carriage more convenient.

[0065] When it is necessary to load and unload the boxed cigarettes, push the folding plate 3. The folding plate 3 drives the first connecting page 511 and the second connecting page 512 to approach each other, and then drives the conveying screw 523 to rotate around the damping screw 524. Through the action of the damping screw 524, the folding plate 3 can slide to a preset position, thus opening the carriage to load and unload the boxed cigarettes. When the carriage needs to be closed after the loading and unloading are completed, directly pull the folding plate 3 to expand the entire folding plate 3, and the carriage is closed.

[0066] Further, in the embodiment of the present invention, the guide rail 6 can also be set as an air cushion guide rail. The setting type of the guide rail 6 is not limited in this embodiment, and those skilled in the art can change the setting type of the guide rail 6 according to the actual situation, as long as the same technical effect can be achieved.

[0067] Further, as Figure 4 shown, the air cushion guide rail includes an air channel 62 and air holes 63. The air channel 62 is arranged inside the air cushion guide rail; the air holes 63 are arranged on the air cushion guide rail and communicate with the air channel 62.

[0068] Further, as Figure 2 shown, the folding device for the freight car carriage further includes an air compressor 7. The air compressor 7 is arranged outside the carriage and is respectively communicated with the air channel 62 through the air holes 63. At the same time, the bearing 42 is made into an air bearing through the air compressor 7. By setting the guide rail 6 as an air cushion guide rail and setting the bearing 42 as an air bearing, the transmission mechanism 4 can be made not to contact the guide rail 6, thereby reducing the sliding friction of the folding plate 3 and improving the automation of the opening and closing of the carriage.

[0069] The specific working process of the folding device for the freight car carriage provided by the present invention is as follows:

[0070] When it is necessary to load and unload the boxed cigarettes, first push the folding plate 3. The folding plate 3 drives the support rod 41 and the bearing 42 to slide in the graphite chute 61, and at the same time drives the first connecting page 511 and the second connecting page 512 to approach each other. The first connecting page 511 and the second connecting page 512 drive the conveying screw 523 to rotate around the damping screw 524 through the connecting piece 526. At the same time, under the action of the damping screw 524, the conveying screw 523 rotates to a predetermined position, that is to say, the folding plate 3 is pushed to a predetermined position, thus opening the carriage to perform the loading and unloading operation of the boxed cigarettes; when the loading and unloading of the boxed cigarettes are completed and the carriage needs to be closed, directly pull the folding plate 3 in the reverse direction.

[0071] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model creation.
