[0065] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0066] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0067] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.

[0068] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0069] First embodiment

[0070] The utility model provides a frame box device. The frame box device includes at least two frame boxes. The frame box can be a 50-foot box. The frame box device is a multi-layer structure. For example, a two-layer structure. This article takes a two-layer structure as an example for explanation. Both layers of the frame box device can be used to transport vehicles. The height size of the corner column assembly of the frame box can be changed. In this way, when the frame box device is loaded with a vehicle, if it is necessary to hoist the frame box, the top of the corner column assembly of the frame box located on the uppermost layer is made higher than the top of the vehicle located on the uppermost layer, so that the corner column assembly of the frame box located on the uppermost layer can be connected by a hoist for hoisting. When the frame box device for loading vehicles is transported by rail, the top of the corner column assembly of the frame box located on the uppermost layer can be made lower than the top of the vehicle located on the uppermost layer, so as to avoid the corner column assembly of the frame box located on the uppermost layer from colliding with objects on both sides of the railway during the railway transportation (such as the top wall of the railway tunnel, etc.).

[0071] Please refer to Figure 1 and Figure 2 The frame box includes a bottom frame 50. The bottom frame 50 is used to carry the vehicle. The bottom frame 50 has a bottom corner piece 21.

[0072] The frame box further includes a corner post assembly. The corner post assembly is connected to the base frame 50. At least part of the corner post assembly is movably arranged. In this way, the corner post assembly has a first state and a second state. When the corner post assembly is in the first state, the length direction of the corner post assembly extends in the vertical direction, so that the height dimension of the corner post assembly is a first dimension. When the corner post assembly is in the second state, the height dimension of the corner post assembly is a second dimension. The first dimension is greater than the second dimension. The corner post assembly has a top corner piece.

[0073] like Figure 1 As shown, when the corner post assembly is in the first state, the corner post assembly is stacked through the top corner fitting and the bottom corner fitting 21 of another frame box. Specifically, the bottom corner fitting 21 of one frame box can be stacked on the top corner fitting of another frame box in which the corner post assembly is in the first state. In this way, the two frame boxes stacked together form a two-layer structure, so that two layers of the first vehicle 70 can be transported.

[0074] In this way, Figure 1As shown, when the frame box loaded with the first vehicle 70 needs to be hoisted by the hoist, the corner post assembly can be placed in the first state. In this way, the top end of the corner post assembly is located higher than the top of the first vehicle 70 located on the bottom frame 50. The hoist can connect the top corner piece located at the top end of the corner post assembly.

[0075] like Figure 2 As shown, when two frame boxes loaded with the first vehicle 70 are stacked together and need to be transported by rail, the movable corner column 12 of the frame box on the upper layer can be located at the second position described later, and the movable corner column 12 of the frame box on the lower layer can be located at the first position described later. At this time, along the vertical direction, the dimension between the top surface (the uppermost surface) of the corner column assembly of the frame box on the upper layer and the bottom surface of the bottom corner piece 21 of the frame box on the lower layer is not greater than the preset dimension. The preset dimension can be determined according to the railway boundary. For example, the preset dimension ranges from 3500 mm to 3600 mm. Further, the preset dimension can be 3570 mm. In this way, the overlapping parts of the corner column assembly and the boundary 80 described later are avoided, thereby avoiding the corner column assembly from being bumped during transportation, and ensuring the safety of transportation by rail.

[0076] Railway limits refer to the outline dimension lines (boundary 80) that cannot be crossed between buildings, equipment and locomotives and vehicles on the line to ensure transportation safety. There are two types: building approach limits and locomotive and vehicle limits, collectively known as the basic limits of railways. The former is the outline line that buildings on both sides of the railway line are not allowed to intrude; the latter is the outline line that locomotives and vehicles themselves and the goods they carry are not allowed to cross, and a certain gap should be left between the two.

[0077] In this embodiment, when the corner post assembly is in the first state, the corner post assembly is stacked by the top corner piece and the bottom corner piece 21 of another frame box to form at least a two-layer structure, thereby being able to transport at least two layers of vehicles, and the transportation efficiency is high; in addition, the setting of the first size being larger than the second size enables the frame box loaded with the vehicle to be hoisted by a hoist and transported by rail.

[0078] Optionally, the corner post assembly includes a movable corner post 12. A movable top corner piece 20 (an example of a top corner piece) is provided at the top end of the movable corner post 12. The movable corner post 12 is pivotally connected to the bottom frame 50. In this way, the movable corner post 12 has a first position and a second position.

[0079] When the movable corner post 12 is located at the first position, the corner post assembly is in the first state. At this time, the length direction of the movable corner post 12 is parallel to the vertical direction.

[0080] When the movable corner post 12 is located at the second position, the corner post assembly is in the second state. At this time, the length direction of the movable corner post 12 extends along the length direction of the base frame 50. The movable corner post 12 is stacked on the base frame 50. Therefore, the structure of the corner post assembly is simple.

[0081] Second embodiment

[0082] In the second embodiment, if Figures 3 to 7 As shown, the corner post assembly 110 includes a fixed corner post 111. The bottom end of the fixed corner post 111 is connected to the bottom frame 150.

[0083] The corner post assembly 110 further includes a movable corner post 112. The top corner piece includes a movable top corner piece 120 located at the top end of the movable corner post 112. The movable corner post 112 is connected to the fixed corner post 111. In this way, the movable corner post 112 has a first position and a second position.

[0084] When the movable corner post 112 is located at the first position, the corner post assembly 110 is in the first state. At this time, the length direction of the movable corner post 112 and the length direction of the fixed corner post 111 are both parallel to the vertical direction. The top of the movable corner post 112 is higher than the top of the fixed corner post 111. The height dimension of the whole formed by the movable corner post 112 and the fixed corner post 111 is the first dimension.

[0085] When the movable corner post 112 is located at the second position, the corner post assembly 110 is in the second state. The height dimension of the whole formed by the movable corner post 112 and the fixed corner post 111 is the second dimension.

[0086] In this way, the height of the corner post assembly 110 can be adjusted. In this way, when transporting at least two layers of vehicles, for the frame box located at the lower layer, the height of the corner post assembly 110 can be adjusted according to the height of the vehicle it carries. In this way, it can be suitable for transporting vehicles of different heights. For example, the chassis 150 located at the upper layer is used to carry the first vehicle 170. The chassis 150 located at the lower layer is used to carry the second vehicle 171. The height of the second vehicle 171 can be greater than the height of the first vehicle 170. The height of the corner post assembly 110 of the frame box located at the lower side can be adjusted according to the height of the second vehicle 171.

[0087] It will be appreciated that in an embodiment not shown, the height of the second vehicle may be equal to or less than the height of the first vehicle.

[0088] Optionally, refer to Figures 2 to 7 , the movable corner post 112 is movable in the vertical direction relative to the fixed corner post 111. In this way, the movable corner post 112 can move between the first position and the second position. In this way, the corner post assembly 110 can be extended and retracted. Therefore, the structure of the corner post assembly 110 is simple.

[0089] Alternatively, if Figure 4 and Figure 5 As shown, the movable corner post 112 is inserted through the fixed corner post 111. In this way, the structure of the frame box is simple.

[0090] It can be understood that in an embodiment not shown, the movable corner post can be located to the side of the fixed corner post in the horizontal direction.

[0091] like Figure 4 and Figure 5 As shown, the movable corner post 112 has a movable body 116 and a first operating portion 118. The movable body 116 is inserted into the fixed corner post 111. The first operating portion 118 is formed by the movable body 116 extending outward horizontally. The fixed corner post 111 has an escape hole 115. The first operating portion 118 passes through the escape hole 115 and extends outside the fixed corner post 111. In this way, the first operating portion 118 can be moved up and down by a forklift, thereby moving the movable corner post 112 between the first position and the second position. In this way, when the drive assembly 130 described later fails, the first operating portion 118 can be moved up and down by a forklift.

[0092] Optionally, the first operating portion 118 is connected to a lower end of the movable body 116 .

[0093] like Figure 4 As shown, the frame box further includes a driving assembly 130. The driving assembly 130 may be a hydraulic cylinder. The driving assembly 130 is connected to the fixed corner column 111 and the movable corner column 112 to drive the movable corner column 112 to move between the first position and the second position in the vertical direction. Thus, it is convenient to drive the movable corner column 112 to move between the first position and the second position. It can be understood that in an embodiment not shown, the driving assembly may also be a linear driving member, such as a motor, a combination of a rack and a gear, a cylinder, etc.

[0094] Alternatively, if Figure 4 As shown, the driving assembly 130 is located in the fixed corner column 111. Thus, the driving assembly 130 can be protected.

[0095] like Figure 4 As shown, the driving assembly 130 is located below the movable corner post 112. The top end of the driving assembly 130 is connected to the movable corner post 112. The lower end of the driving assembly 130 is connected to the fixed corner post 111. The lower end of the driving assembly 130 is located at the upper surface of the base frame 150. The driving assembly 130 is detachably arranged. The fixed corner post 111 has a maintenance notch 113 corresponding to the driving assembly 130. The maintenance notch 113 is located at the driving assembly 130. The maintenance notch 113 is separated from the avoidance hole 115. Therefore, the driving assembly 130 can be replaced through the maintenance notch 113.

[0096] like Figure 4As shown, the frame box further includes a second operating portion 131. The second operating portion 131 passes through the avoidance hole 115 and extends to the outside of the fixed corner column 111. In this way, the second operating portion 131 can act on the driving assembly 130, thereby driving the driving assembly 130 to work.

[0097] Specifically, the second operating portion 131 is rotatably connected to the driving assembly 130. In this way, the second operating portion 131 moves between the original position and the driving position. When the second operating portion 131 moves from the original position toward the driving position, the driving assembly 130 can be driven to work, thereby causing the movable corner post 112 to move upward from the second position toward the first position.

[0098] like Figure 4 As shown, the frame box further includes a movable reset member 193. The movable reset member 193 is a spring. The movable reset member 193 is connected to the second operating portion 131 and the fixed angle column 111 to apply a force to the second operating portion 131 to move the second operating portion 131 toward the original position. In this way, the second operating portion 131 can automatically return to the original position, which is convenient for operation.

[0099] Furthermore, the driving assembly 130 may be a foot-operated hydraulic cylinder, and the second operating part 131 may be a pedal, thereby facilitating operation.

[0100] In an embodiment not shown, the driving assembly may also be a lever cylinder or an electronically controlled hydraulic cylinder.

[0101] Optionally, refer to Figures 4 to 7 , the fixed corner column 111 has a first limiting hole 114. The movable corner column 112 has a second limiting hole 117. The second limiting hole 117 corresponds to the first position of the movable corner column 112. The frame box further includes a limiting pin 140. When the movable corner column 112 is located at the first position, part of the first limiting hole 114 is located at the second limiting hole 117. At this time, the limiting pin 140 is inserted through the first limiting hole 114 and the second limiting hole 117 to fix the movable corner column 112 to the fixed corner column 111. In this way, the movable corner column 112 can be locked in the first position.

[0102] Alternatively, if Figure 7 As shown, there are at least two (for example, two) second limiting holes 117. Thus, the limiting pin 140 is selectively inserted into one of the second limiting holes 117. Thus, the movable corner post 112 can be fixed to two positions of the fixed corner post 111.

[0103] Alternatively, if Figure 4As shown, the fixed corner column 111 includes a fixed body and a mounting seat 144 connected to the fixed body. The movable body 116 is inserted into the fixed body. The mounting seat 144 is formed by the outer peripheral surface of the fixed body extending outward horizontally. The limit pin 140 is located below the mounting seat 144. The limit pin 140 is movably connected to the mounting seat 144 along the horizontal direction. In this way, the limit pin 140 can move between the limit position and the departure position. When the limit pin 140 is located at the limit position, the limit pin 140 is inserted into the first limit hole 114 and the second limit hole 117. At this time, the movable corner column 112 is fixed to the fixed corner column 111. When the limit pin 140 is located at the departure position, the limit pin 140 leaves the second limit hole 117. At this time, the movable corner column 112 can move relative to the fixed corner column 111. In this way, the limit pin 140 can be prevented from being lost.

[0104] Furthermore, if Figure 6 As shown, the limit pin 140 has a limit operating portion 141 extending downward and protruding. Therefore, the limit operating portion 141 can be turned to move the limit pin 140.

[0105] Please continue to refer to Figure 6 The frame box further includes a stopper 142. The stopper 142 is a sheet metal part. The stopper 142 is located below a portion of the mounting seat 144. The stopper 142 is rotatably connected to the mounting seat 144. The rotation axis of the stopper 142 and the moving direction of the stopper pin 140 form an angle (e.g., vertical).

[0106] In this way, the stopper 142 can rotate between the blocking position and the release position. Figure 6 As shown, when the limiting member 142 is located at the blocking position and the limiting pin 140 is located at the limiting position, the limiting member 142 is located at the side of the limiting operating portion 141 along the moving direction of the limiting pin 140 to block the limiting operating portion 141, thereby preventing the limiting pin 140 from leaving the limiting position. In this way, the limiting pin 140 can be prevented from leaving the limiting position.

[0107] When the limiting pin 140 needs to be moved to the leaving position, the limiting member 142 can be rotated to the releasing position. At this time, the limiting member 142 no longer blocks the limiting operating portion 141. The limiting pin 140 can be moved to the leaving position.

[0108] Please continue to refer to Figure 6 The frame box further includes a limit reset member 143. The limit reset member 143 is a spring. The limit reset member 143 is connected to the limit member 142 and the mounting seat 144 to apply a force to the limit member 142 to move the limit member 142 toward the blocking position. Thus, the limit member 142 that has left the blocking position can automatically return to the blocking position, which is convenient for operation.

[0109] like Figure 4 and Figure 5 As shown, a headband 122 for blocking the movable top corner piece 120 is provided at the top end of the fixed corner post 111. The headband 122 is a cast steel part. The headband 122 is fixedly connected (for example, welded) to the top end of the fixed corner post 111. The headband 122 is sleeved on the movable body 116. The projection of the headband 122 on the horizontal plane partially overlaps with the projection of the movable top corner piece 120 on the horizontal plane. In this way, when the movable corner post 112 is in the second position, the movable top corner piece 120 is overlapped to the headband 122. At this time, the headband 122 supports the movable top corner piece 120, thereby blocking the movable corner post 112 from continuing to move downward away from the first position.

[0110] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0111] Third embodiment

[0112] In the third embodiment, if Figures 8 to 10 As shown, the movable corner post 212 is rotatably connected to the top end of the fixed corner post 211 to rotate between a first position and a second position. When the movable corner post 212 is in the first position, the bottom end of the movable corner post 212 overlaps the top end of the fixed corner post 211. Thus, the movable corner post 212 can be prevented from being lost.

[0113] After the movable corner post 212 leaves the first position, the movable corner post 212 can automatically flip to the second position under the action of its own gravity. When the movable corner post 212 is in the second position, the length direction of the movable corner post 212 is parallel to the length direction of the fixed corner post 211 and is located to the side of the fixed corner post 211. Thus, the horizontal size of the movable corner post 212 in the second position can be reduced.

[0114] Furthermore, if Fig.10 As shown, one end of the movable corner post 212 provided with a rotary lock 216 described later extends and protrudes to form a first lug 213. There are two first lugs 213. The two first lugs 213 are arranged at intervals. The top end of the fixed corner post 211 extends and protrudes in the horizontal direction to form a second lug 214. There are two second lugs 214. The two second lugs 214 are arranged at intervals.

[0115] The frame box further includes a pivot shaft 215. The second lug 214 is located between the two first lugs 213. The pivot shaft 215 passes through the first lug 213 and the second lug 214. In this way, the movable corner post 212 is pivotally connected to the fixed corner post 211 through the pivot shaft 215. The pivot shaft 215 is located on the side of the fixed corner post 211 in the horizontal direction. As a result, the structures of the movable corner post 212 and the fixed corner post 211 are simple.

[0116] Alternatively, if Figures 8 to 10As shown, a rotary lock 216 is provided at the bottom end of the movable corner post 212. The rotary lock 216 may be an existing rotary lock for containers, which will not be described in detail here. A fixed top corner piece 222 is provided at the top end of the fixed corner post 211. When the movable corner post 212 is located at the first position, the rotary lock 216 extends into the fixed top corner piece 222 and can be locked to the fixed top corner piece 222. In this way, the movable corner post 212 located at the first position can be prevented from leaving the first position during the hoisting process.

[0117] Alternatively, if Fig.10 As shown, the rotary lock 216 has a rotary lock handle 217. The rotary lock handle 217 is located in the movable corner column 212. The movable corner column 212 has an operating hole 218. The position of the operating hole 218 corresponds to the position of the rotary lock handle 217. In this way, the operating hole 218 is directly opposite to the rotary lock handle 217, and the rotary lock handle 217 can be operated through the operating hole 218. Therefore, the rotary lock 216 can be prevented from being misoperated. In addition, the operating hole 218 can reduce the weight of the movable corner column 212, thereby facilitating the operation of the movable corner column 212.

[0118] Alternatively, if Fig.10 As shown, the rotary lock 216 is located at the lower end surface of the movable corner post 212 (the lower end surface of the movable corner post 212 when the movable corner post 212 is located at the first position). The fixed top corner piece 222 has a top corner hole 223. When the movable corner post 212 is located at the first position, the rotary lock 216 extends into the top corner hole 223 of the fixed top corner piece 222. Therefore, the structure of the movable corner post 212 is simple.

[0119] Optionally, a movable top corner piece 220 is provided at the top end of the movable corner post 212. A bottom corner piece 221 is provided at the bottom end of the fixed corner post 211. When the movable corner post 212 is located at the first position, the frame boxes can be stacked by the movable top corner piece 220 of the movable corner post 212 and the bottom corner piece 221 of the fixed corner post 211. When the movable corner post 212 is located at the second position, the frame boxes can be stacked by the fixed top corner piece 222 of the fixed corner post 211 and the bottom corner piece 221 of the fixed corner post 211. The frame boxes can also be hoisted by the fixed top corner piece 222 of the fixed corner post 211 or the movable top corner piece 220 of the movable corner post 212.
