Description

Technical Field

[0001] The present invention relates to the field of containers, in particular to a vehicle transport container. Background Art

[0002] The vehicle transport container is generally a standard container equipped with a transport frame for the reinforcement and transportation of vehicles. The transport frame is divided into two layers, both of which can be used to place vehicles. Figure 1 As shown, one end of the upper transport frame is hinged and fixed, and the other end is adjusted up and down. By adjusting the lower position, the vehicle can be driven onto the upper transport frame, and by adjusting the upper position, the upper transport frame can be lifted and fixed to reserve a placement space for the vehicle to drive into the lower transport frame. The adjustment and fixation of the upper transport frame require the help of a forklift. The forklift needs to drive into the box to lift the upper transport frame and maintain a certain height to ensure that the upper transport frame is smoothly fixed. The above operation process is complicated and laborious; and the vehicle needs to be driven into the transport frame in the box to be fixed. When the vehicle body is wide, the driver may not be able to open the door and get out of the car after driving into the box. At the same time, the operator may not be able to enter the box to fix the vehicle, especially the operating space on the inner side of the container (the end without the door) is smaller. In this way, the transport container originally suitable for small and medium-sized vehicles may not be suitable for loading large vehicles such as SUVs. Summary of the Invention

[0003] The object of the present invention is to provide a vehicle transport container to solve the problems raised in the background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The utility model comprises a box body and a vehicle transporting frame arranged inside the box body, the box body comprises a bottom frame, a wall panel and a box door arranged at at least one end of the bottom frame, and further comprises a moving mechanism connecting the box body and the vehicle transporting frame; the vehicle transporting frame enters and exits the box body from the box door through the moving mechanism, so that the vehicle transporting frame loads and unloads vehicles outside the box body.

[0006] As a result, the vehicle transport frame can be extended to the outside of the box, enabling the loading and unloading of vehicles outside the box, and increasing the width selection range of vehicles.

[0007] Preferably, the moving mechanism comprises a first-layer moving mechanism, and the transport frame comprises a first-layer frame; the first-layer moving mechanism comprises a first caster disposed at the bottom of the first-layer frame, and the first caster is in rolling engagement with the base frame. Thus, the first-layer frame can move forward and backward on the base frame, facilitating loading and unloading of the first-layer frame.

[0008] Preferably, side guide wheels are provided on both sides of the first layer frame, and the side guide wheels are in rolling cooperation with the wall panels. Thus, the first layer frame can move forward and backward more stably through the cooperation between the side guide wheels and the wall panels, without shaking left and right.

[0009] Preferably, the bottom frame has a threshold at the end to increase the friction between the front end of the first layer of frames and the bottom frame when the first layer of frames is tilted. Thus, the front end rests on the threshold and the rear end rests on the ground. The different tilt angles can also increase the contact area between the rear end and the ground, thereby increasing the friction between the rear end and the ground, thereby preventing the first layer of frames from being easily moved during loading and unloading.

[0010] Preferably, the container further comprises a front end limiting mechanism, which limits the front end of the first layer of the frame when the first layer of the frame is in a loaded state, so that the front end of the first layer of the frame can be limited when transporting the container.

[0011] Preferably, the front-end limiting mechanism for the first layer includes a first limiting plate provided on the base frame, which engages with the front end of the first layer of the frame to limit the front end of the first layer of the frame. Thus, a locking structure between the base frame and the front end is provided, which can prevent the front end of the first layer of the frame from colliding with the box when loading the first layer of the frame, and at the same time, the locking structure makes the front end of the first layer of the frame more tightly limited.

[0012] Preferably, the container further comprises a first-layer tail end limiting mechanism, which limits the tail end of the first-layer frame when the first-layer frame is in a loaded state, so that the tail end of the first-layer frame can be limited when transporting the container.

[0013] Preferably, the first-stage tail-end limiting mechanism includes a first limiting plate provided on the base frame, which engages with the tail end of the first-stage frame to limit the tail end of the first-stage frame. Thus, a locking structure between the base frame and the tail end is provided, which can be used to limit the tail end of the first-stage frame when two stages of frames enter the box on the same side.

[0014] Preferably, the first-stage rear end limit mechanism includes a second limit plate provided on the box door, which engages with the rear end of the first-stage frame to limit the rear end of the first-stage frame. Thus, a locking structure between the box door and the rear end is provided, which can be used to limit the position of the first-stage frame at the rear end near the box door after entering the box.

[0015] Preferably, the chassis is provided with a turning slot, and the tail of the first limiting plate is rotatably connected to the turning slot via a rotating shaft. When the first limiting plate is fully rotated into the turning slot, it is flush with the chassis surface and does not occupy space within the box. When the first limiting plate is rotated perpendicular to the turning slot, it acts as a limiter. This provides a first limiting plate that can be hidden on the chassis and kept closed when not in use, allowing for in-box testing or to facilitate the passage of vehicles on one level.

[0016] Preferably, the tail end of the first layer frame is provided with a mounting groove and a second limiting block, the mounting groove is provided with an adjusting pin, the second limiting block is provided with a plurality of adjusting holes distributed along the length direction, the adjusting pin is inserted into different adjusting holes to adjust the length of the second limiting block entering the mounting groove, and the tail end of the second limiting block can be buckled with the tail end limiting mechanism of the first layer, so as to be limited. Therefore, the length of the first layer frame can be adjusted by the adjusting pin, so that the first layer frame can be telescoped, thereby better matching the limiting structure of the tail end.

[0017] Preferably, the box is provided with the box door at one end and is closed at the other end; the first layer frame is provided with two, and the two first layer frames enter and exit the box in turn from the box door. Therefore, when the box is opened at one end, the first layer frame can be loaded and unloaded in turn.

[0018] Preferably, the box is provided with the box door at both ends, and the first layer frame is symmetrically provided with two, and the two first layer frames enter and exit the box from the box doors at both ends respectively. Therefore, when the box is opened at both ends, the first layer frame can be loaded and unloaded at the same time.

[0019] Preferably, the moving mechanism comprises a second layer moving mechanism, and the trolley frame comprises a second layer frame; the second layer moving mechanism comprises a guide rail arranged on the wallboard and a second caster arranged on both sides of the second layer frame, and the second caster is in rolling cooperation with the guide rail. Therefore, through the guide rail structure, the second layer frame can enter and exit the inside of the box.

Therefore, a whole inclined guide rail style is provided, and the horizontal structure at both ends of the guide rail can also make the entering and exiting of the second layer frame more stable and convenient.

[0021] Preferably, the lower end is further provided with a limiting part, which is used for supporting and limiting the front end of the second layer frame when the second layer frame is inclined. Therefore, the front end of the second layer frame is increased in friction with the guide rail at the limiting part, and the tail end falls on the ground, increasing the contact area of the tail end with the ground, thereby increasing the friction of the tail end with the ground, and further preventing the second layer frame from being easily moved when loading and unloading the vehicle.

[0022] Preferably, the guide rail is horizontally arranged on the inner side of the wallboard. Therefore, a whole horizontal guide rail style is provided, which is easier to manufacture than the inclined guide rail and does not require additional structural design.

[0023] Preferably, the guide rail further comprises a third horizontal part, which is horizontally arranged on the wall plate, and two ends of the third horizontal part are the upper end part and the side end part respectively, and the side end part is located at the side of the wall plate. Thus, a guide rail pattern combining horizontal and inclined is provided, and the two-layer frame is more simple and convenient to enter and exit the box from the inclined part.

[0024] Preferably, the two-layer front end limiting mechanism is further provided, and when the two-layer frame is in the loading state, the two-layer front end limiting mechanism limits the front end of the two-layer frame. Thus, the front end of the two-layer frame can be limited when the container is transported.

[0025] Preferably, the two-layer front end limiting mechanism comprises a baffle arranged on the wall plate, and the baffle is buckled with the front end of the two-layer frame.

[0026] Preferably, the two-layer front end limiting mechanism comprises a baffle arranged on the wall plate, and the baffle is buckled with the front end of the two-layer frame. Thus, a simple buckling structure of the wall plate and the front end is provided, which can be used to limit the front end of the two-layer frame when the two-layer frame enters the box from both sides respectively.

[0027] Preferably, the two-layer tail end limiting mechanism is further provided, and when the two-layer frame is in the loading state, the two-layer tail end limiting mechanism limits the tail end of the two-layer frame. Thus, the tail end of the two-layer frame can be limited when the container is transported.

[0028] Preferably, the two-layer tail end limiting mechanism comprises a baffle arranged on the wall plate, and the baffle is buckled with the front end of the two-layer frame. Thus, a simple buckling structure of the wall plate and the front end is provided, which can be used to limit the front end of the two-layer frame when the two-layer frame enters the box from both sides respectively.

[0030] Preferably, a limiting ring is arranged on the limiting shaft, and the limiting ring is arranged at the connection between the unlocking piece and the limiting shaft, so as to limit the axial position of the unlocking piece relative to the limiting shaft, so that the unlocking piece can drive the limiting shaft to move axially.

[0054] Please refer to Figures 2 to 20 , the present application discloses a vehicle carrying container, which is further described in detail in combination with the accompanying drawings.

[0055] The present application provides a vehicle carrying container, which comprises a box body and a vehicle frame arranged inside the box body. The box body comprises a base frame 1, wall plates 3 and container doors 2 arranged at least one end of the base frame. The container doors 2 are opened from the middle to both sides, and the corresponding end of the base frame 1 has a door sill 11. The box body and the vehicle frame are connected through a moving mechanism and a limiting mechanism. The vehicle frame enters and exits the box body through the moving mechanism, so that the vehicle frame loads and unloads vehicles outside the box body. When the vehicle frame is loaded with vehicles and all the vehicles are placed in the box body, the vehicle frame is in a loaded state, at which time the vehicle carrying container can be transported, and the vehicle frame is horizontally fixed in the box body through the limiting mechanism. Among the two ends of the vehicle frame along the length direction, the end entering the box body first is the front end, and the end entering the box body later is the tail end.

[0056] Based on the above basic scheme, the present application provides a vehicle carrying container as shown in Figure 2 and Figure 6 The inside of the box body is provided with two layers of vehicle frames, i.e. one layer of vehicle frame 4a and two layers of vehicle frame 4b. Each layer of vehicle frame is symmetrically provided with two vehicle frames. The box body is provided with container doors 2 at both ends, and the doors are opened at both ends of the box body. The two vehicle frames of the same layer enter and exit the box body from both ends of the box body. Figure 7 and Figure 12Each of the vehicle frames comprises a front beam 41 at the front end, two side beams 42 at the outermost sides, two symmetrical vehicle lanes 43 between the side beams 42, and a fork groove 44 between the vehicle lanes 43, the fork groove 44 being close to the tail end of the vehicle frame, so as to facilitate the external forklift to move the vehicle frame from the outside of the box body.

[0057] Generally, the height of the 40FT standard container cannot meet the requirement of placing double-layer SUVs and other large vehicles, so in order to realize that each layer of the vehicle frame can accommodate the largest SUV model, the transport container inherits the length and width dimensions and functions of the 40-foot container, increases a cross beam 33 in the middle of the wall plate 3, welds the related guide rail 34 of the second layer of vehicle frame 4b for reinforcement, and improves the strength of the wall plate 3. The wall plate 3 is divided into an upper wall plate 31 and a lower wall plate 32 by the cross beam 33, and the height of the upper wall plate 31 and the lower wall plate 32 is adjusted accordingly. The upper wall plate 31 corresponds to the vehicle placed on the second layer of vehicle frame 4b, and the lower wall plate 32 corresponds to the vehicle placed on the first layer of vehicle frame 4a. Thus, the high vehicle transport container can realize the fixation and transportation of four SUVs.

[0058] For the two-layer vehicle frame in the present application, in addition to the same basic structure as described above, the structures for entering and exiting the box body and limiting locking of different layers of vehicle frames are different. Each first layer of vehicle frame 4a is correspondingly provided with a first layer of moving mechanism and a first layer of limiting mechanism, and each second layer of vehicle frame 4b is correspondingly provided with a second layer of moving mechanism and a second layer of limiting mechanism. The specific structure is as follows:

[0059] As shown in Figure 7 The first layer of moving mechanism comprises a first caster wheel 4a1 arranged at the bottom of the front end of the first layer of vehicle frame 4a and a side guide wheel 4a2 arranged at both sides of the first layer of vehicle frame 4a. The front end of the first layer of vehicle frame 4a is provided with four short beams 4a6 perpendicular to the front beam 41, and the bottom of each short beam 4a6 is provided with a first caster wheel 4a1, and a total of four first caster wheels 4a1 are in rolling cooperation with the chassis 1 of the container. At the same time, a heightening block is arranged at the bottom of the beam close to the tail end of the first layer of vehicle frame 4a, so that the tail end and the front end of the first layer of vehicle frame 4a are kept at the same horizontal height, and the first layer of vehicle frame 4a can be horizontally placed on the chassis 1. The side guide wheel 4a2 is provided with two groups, a total of four, one group is arranged at both ends of the front beam 41, and the other group is arranged at the tail end of the two side beams 42. The four side guide wheels 4a2 are in rolling cooperation with the wall plate 3 of the container, and a side buffer block 4a3 is arranged at the horizontal outer side of the side beam 42, respectively close to the four side guide wheels 4a2. The side buffer block 4a3 and the side guide wheel 4a2 jointly play a guiding role when the first layer of vehicle frame 4a enters and exits the box body.

[0060] In combination with Figure 18In the last few steps, the outer fork of the forklift enters the fork groove 44 and lifts the tail end of the layer frame 4a when the layer frame 4a enters and exits the box, and the forklift moves forward and backward to make the layer frame 4a enter and exit the box through the first caster 4a1. The door sill 11 at both ends of the chassis 1 has a certain height and can play a certain limiting role when the layer frame 4a is pulled out by the forklift, preventing the front end of the layer frame 4a from sliding out of the chassis 1. After the main body of the layer frame 4a is pulled out of the box, the front end of the layer frame 4a is placed on the door sill 11, and at this time the first caster 4a1 is in a state of being empty, and the tail end falls on the ground, so as to be placed obliquely, facilitating the vehicle to enter or exit the layer frame 4a outside the box. At this time, the layer frame is inclined, the door sill 11 increases the friction between the front end and the chassis 1, and the inclined placement also increases the contact area between the tail end and the ground, thereby increasing the friction between the tail end and the ground, and further preventing the layer frame 4a from being easily moved when loading and unloading the vehicle.

[0061] In combination Figures 7 to 10 The layer limiting mechanism includes a front end limiting mechanism and a tail end limiting mechanism. The front end limiting mechanism includes a first limiting plate 14 arranged on the chassis 1 and a first limiting block 4a4 arranged on the front end of the layer frame 4a. The first limiting block 4a4 can be buckled with the first guide groove 12, and when buckled, the front end of the layer frame 4a is limited. Two first limiting blocks 4a4 are fixedly arranged in front of the horizontal front beam 41 of the layer frame 4a, and two first limiting plates 14 are arranged on the chassis 1 corresponding to each layer frame 4a, that is, four first limiting plates 14 are arranged on the chassis 1 in total. Each first limiting plate 14 has two positions of opening and closing, and the specific implementation scheme is that the chassis 1 is provided with a turnover groove 13, the turnover groove 13 is concave on the surface of the chassis 1, and the inside of the turnover groove 13 is provided with a rotating shaft 15 and a first limiting plate 14. The tail of the first limiting plate 14 is rotatably connected to the chassis 1 through the rotating shaft 15, the head of the first limiting plate 14 is provided with a first guide groove 12, and the first limiting plate 14 makes the first guide groove 12 turn into or out of the turnover groove 13 through the rotating shaft 15. When the first guide groove 12 turns into the turnover groove 13, the first limiting plate 14 is closed, the entire first limiting plate 14 is in the turnover groove 13, and is flush with the surface of the chassis 1, without occupying the space in the box. At this time, the test in the box can be done, or the first limiting plate 14 can be kept closed when the vehicle carrying container is not used. When the first guide groove 12 turns out of the turnover groove 13, the first limiting plate 14 can only be turned to be perpendicular to the chassis 1 due to the block of the chassis 1, and cannot continue to turn outwards. At this time, the first limiting plate 14 is opened, and the first guide groove 12 is convex on the surface of the chassis 1. After the layer frame 4a enters the inside of the box, the first limiting block 4a4 is inserted into the first guide groove 12, that is, the mutual buckling with the first limiting plate 14 is realized, so as to limit the front end of the layer frame 4a. Therefore, after the layer frame 4a is loaded with vehicles, the first guide groove 12 needs to be opened before entering the inside of the box.

[0062] Combine Figure 7 and Figure 11 The first-layer tail-end limiting mechanism includes a second limiting plate 21 provided on the inner side of the box door 2 and a second limiting block 4a5 provided at the tail end of the first-layer frame 4a. The tail ends of the two side beams 42 of the first-layer frame 4a are provided with mounting grooves along their length. Two second limiting blocks 4a5 are provided, which are respectively nested with the tail ends of the side beams 42. The front ends of the second limiting blocks 4a5 enter the mounting grooves from the tail ends of the side beams 42, that is, the second limiting blocks 4a5 and the side beams 42 have overlapping portions. An adjustment pin 4a7 is provided at the tail end of the side beam 42. The second limiting block 4a5 is provided with a plurality of adjustment holes distributed along the length direction. When the adjustment pin 4a7 is inserted into different adjustment holes, the length of the second limiting block 4a5 entering the mounting groove can be adjusted, that is, the total length of the entire side beam 42 and the first-layer frame 4a. After adjusting the second stopper 4a5 with the latch 4a7, the rear end of the second stopper 4a5 engages with the second stopper plate 21 when the length of the first layer of the vehicle frame 4a is at its maximum. Two second stopper plates 21 are also provided, one on each side of the door 2, corresponding one to each of the second stopper 4a5. After the first layer of the vehicle frame 4a enters the vehicle frame and the front end engages, closing the door 2 causes the second stopper 4a5 to engage with the second stopper plate 21, thereby limiting the rear end of the first layer of the vehicle frame 4a.

[0063] The front-end limiting mechanism of one layer and the rear-end limiting mechanism of one layer jointly realize the overall fixation of the vehicle frame 4a of one layer.

[0064] Combine Figure 12 and Figure 13The second layer moving mechanism includes guide rails 34 arranged inside the wall plate 3 and second casters 4b1 arranged at the front end of the second layer frame 4b. The second casters 4b1 roll with the guide rails 34, that is, two guide rails 34 are arranged on each side of the second layer frame 4b. The second casters 4b1 are arranged at the bottom of the side beam 42 and protrude outwardly from the side beam 42, so that the side beam 42 does not collide with the guide rails 34 when the second casters 4b1 slide on the guide rails 34. The guide rails 34 are inclined from low to high along the inside of the wall plate 3 from the low position close to the box door 2 to the vertical axis of the wall plate 3. The two ends of the guide rails 34 are an upper end 341 and a lower end 342. From the lower end 342 to the upper end 341, the guide rails 34 include a first horizontal portion 344, an inclined portion 345, and a second horizontal portion 346 in sequence. The inclined portion 345 and the first horizontal portion 344 are connected by an arc-shaped portion 347. The second horizontal portion 346 and the inclined portion 345 are connected by an arc-shaped portion 347. The upper end 341 and the second horizontal portion 346 of the guide rails 34 are welded to the cross beam 33, and the remaining portions are welded to the lower wall plate 32. The two horizontal portions of the guide rails 34 have a buffering and assisting effect when the second layer frame 4b enters the inside of the box, so that the movement of the second layer frame 4b is more stable. The lower end 342 is provided with a limiting portion 343 for preventing the second casters 4b1 from sliding out of the guide rails 34.

[0065] The second layer limiting mechanism includes a second layer front end limiting mechanism and a second layer tail end limiting mechanism. Figure 14 The second layer front end limiting mechanism includes a baffle plate 35 arranged on the cross beam 33, and the baffle plate 35 is arranged at the upper end 341 of the guide rail 34. The middle part of the cross beam 33 is provided with a fixed block 36, and the opposite sides of the fixed block 36 are provided with the baffle plate 35. For the second layer frame 4b, the side beam 42 is more protruding than the front beam 41, which can better make the baffle plate 35 and the corresponding front end of the side beam 42 just fit, and when fitting, the front end of the second layer frame 4b is limited.

[0066] In combination with Figures 15 to 17 The second layer tail end limiting mechanism includes an elastic self-locking mechanism 37 arranged inside the wall plate 3, a limiting plate 38, and a pad 4b2 arranged at the tail end of the second layer frame 4b. The elastic self-locking mechanism 37 is arranged at the end of the cross beam 33, the limiting plate 38 is arranged above the elastic self-locking mechanism 37, and the pad 4b2 is arranged at the horizontal outer side of the side beam 42. The limiting plate 38 is parallel to the side beam 42 and can limit the rising height of the tail end of the side beam 42, and at the same time, the pad 4b2 and the elastic self-locking mechanism 37 can be automatically fitted and locked, thereby limiting the backward movement of the second layer frame 4b.

[0067] The elastic self-locking mechanism 37 comprises a support plate 371, a limiting shaft 372, a limiting block 373, a spring 374, a connecting piece 376 and an unlocking piece 375. The support plate 371 is horizontally fixed to the crossbeam 33. The top end of the limiting shaft 372 is fixed with the limiting block 373. The limiting shaft 372 is perpendicular to the support plate 371, and the support plate 371 has a through hole for the limiting block 373 to pass through. The spring 374 and the connecting piece 376 are sleeved on the limiting shaft 372. One end of the spring 374 abuts against the limiting block 373, and the other end abuts against the connecting piece 376. The connecting piece 376 is fixed to the lower wall plate 32. In order to protect the spring 374, a protection piece 379 is further arranged outside the spring 374. One side of the protection piece 379 is fixed to the crossbeam 33 and frames the spring 374 inside.

[0068] The unlocking piece 375 is in the form of a handle in this embodiment. One end of the unlocking piece 375 is fixedly connected with the limiting shaft 372 in the axial direction, and the other end is arranged at different positions to switch the elastic self-locking mechanism 37 between the free state, the locked state and the unlocked state. A limiting ring 378 is arranged on the limiting shaft 372. The limiting ring 378 is arranged at the connection between the unlocking piece 375 and the limiting shaft 372, so as to limit the axial position of the unlocking piece 375 relative to the limiting shaft 372, and enable the unlocking piece 375 to drive the limiting shaft 372 to move in the axial direction. The free end of the unlocking piece 375 is provided with a lock hole 3751. A first lock buckle 3752 and a second lock buckle 3753 which can cooperate with the lock hole 3751 are fixedly arranged on the wall plate 3. The first lock buckle 3752 and the second lock buckle 3753 are located on the same vertical line, and the first lock buckle 3752 is higher than the second lock buckle 3753.

[0069] When the unlocking piece 375 is not connected with any lock buckle, the elastic self-locking mechanism 37 is in the free state, as shown in FIG. 4. Figure 15 The limiting shaft 372 and the limiting block 373 can move in the axial direction without limitation. At this time, the upper half of the limiting block 373 passes through the support plate 371, and a slope 377 is arranged on the side of the upper half of the limiting block 373 which faces the cabinet door 2 from low to high. When the cushion block 4b2 moves along the support plate 371 in the direction shown in the figure, the slope 377 is pressed down, and after passing through the limiting block 373, the limiting block 373 is reset, so as to realize the limiting and locking of the tail end of the two-layer frame 4b.

[0070] When the unlocking piece 375 is connected with the first lock buckle 3752, the elastic self-locking mechanism 37 is in the locked state, as shown in FIG. 5. Figure 16 The limiting shaft 372 and the limiting block 373 are axially fixed and cannot be moved at will, so that the structure of the elastic self-locking mechanism 37 is more stable.

[0071] When the unlocking piece 375 is connected with the second lock buckle 3753, the elastic self-locking mechanism 37 is in the unlocked state, as shown in FIG. 6. Figure 17When the second-layer vehicle frame 4b needs to be pulled out, the unlocking member 375 rotates out from the first lock buckle 3752, driving the limiting shaft 372 to move downward and then rotate to connect with the second lock buckle 3753. At this time, the limiting block 373 moves downward along with the limiting shaft 372. The limiting block 373 no longer passes through the support plate 371 but is hidden under the support plate 371, thereby releasing the lock of the elastic self-locking mechanism 37.

[0072] The key to unlocking lies in the position of the limit block 373. Therefore, in addition to the handle structure shown in the figure, a rope can also be used to hook the end of the limit shaft 372. When unlocking is required, the rope is pulled down to make the limit block 373 compress the spring 374 until the limit block 373 drops.

[0073] Combine Figure 18 Regarding the steps for pulling out the second-layer frame 4b, the rear end lock must be released first, and then the fork tines of the external forklift enter the fork slots 44. The second-layer frame 4b can be pulled out by moving the forklift backward. After being pulled out, the front end of the second-layer frame 4b is placed on the limit portion 343 of the guide rail 34, and the rear end falls to the ground, forming an inclined position, which facilitates the entry and exit of the second-layer frame 4b from the outside of the box. At this time, the second-layer frame is tilted, and the limit portion increases the friction between the front end and the guide rail. The tilted position also increases the contact area between the rear end and the ground, thereby increasing the friction between the rear end and the ground, thereby preventing the second-layer frame from being easily moved during loading and unloading. When the second-layer frame 4b enters the box, the forklift first lifts the tail end of the second-layer frame 4b so that the forklift can push the front end of the second-layer frame 4b to move along the guide rail 34. The front end of the second-layer frame 4b passes through the first horizontal portion 344 and the inclined portion 345 of the guide rail 34 in sequence. When the second caster 4b1 rises to the highest point, that is, just reaches the second horizontal portion 346, the forklift lifts the tail end until the tail end of the side beam 42 is restricted by the limit plate 38 and then stops lifting. At this time, the tail end and the front end of the second-layer frame 4b are at the same horizontal height. At the same time, the forklift moves forward, and the pad 4b2 at the tail end moves along the support plate 371 until the front end is engaged with the baffle 35 and the pad 4b2 is locked with the elastic self-locking mechanism 37, thereby achieving the fixation of the entire second-layer frame 4b.

[0074] The above structure is a case where doors 2 are provided at both ends of the box body, which is a first embodiment. At the same time, the present invention also provides a case where a door 2 is provided at only one end of the box body, which is a second embodiment. In this second embodiment, each layer of the transport frame enters and exits from one door 2 in sequence. The front end and tail end limiting mechanisms used by the layer frame 4a close to the door 2 are consistent with those in the first embodiment, that is, the front end of the layer frame 4a is engaged with the first limiting plate 14, and the tail end is engaged with the second limiting plate 21; while the front end and tail end of the layer frame 4a away from the door 2 need to be engaged with the first limiting plate 14. The first limiting plate 14 is provided at the front end so that the layer frame 4a does not collide with the wall end on the opposite side of the door 2 when entering the box body, thereby better protecting the box body. For the second layer frame 4b, the guide rails 34 on the same wall panel 3 are no longer symmetrically arranged, but a third horizontal portion 348 is added, such as Figure 19 As shown, the third horizontal portion 348 is horizontally disposed on the wall panel 3, and the two ends of the third horizontal portion 348 are respectively an upper end 341 and a side end 349. That is, the third horizontal portion 348 is a track that continues from the second horizontal portion 346, and the side end 349 is located on the side of the wall panel 3 away from the box door 2. The two double-layer frames 4b enter and exit the box through the box door 2 in sequence. The inner double-layer frame 4b enters the box first. After it reaches a horizontal position, it is pushed horizontally into the third horizontal portion 348 until it is loaded. The front and rear end limit mechanisms of this double-layer frame 4b are consistent with those of the first embodiment, with a baffle 35 at the front end and an elastic self-locking mechanism 37 at the rear end. The outer double-layer frame 4b enters the box later. When it is loaded, the front end of this double-layer frame 4b is limited by the elastic self-locking mechanism 37 arranged in the opposite direction, and the rear end limit mechanism is consistent with the first embodiment, using the elastic self-locking structure 37. When the second-layer frame 4b on the inner side enters the box, it will pass through the elastic self-locking mechanism 37 set in the opposite direction. At this time, the elastic self-locking mechanism 37 should be adjusted to the unlocked state in advance, and then adjusted to the locked state after the second-layer frame 4b passes through; when unloading the second-layer frame on the inner side, the elastic self-locking mechanism 37 needs to be adjusted to the free state in advance.

[0075] In the first embodiment, the main body of the guide rail 34 is inclined relative to the length of the container, but the style and height of the guide rail 34 on the inner side of the wall panel 3 can be customized based on the height of the container and the height of the vehicle. The present invention also provides a third embodiment in which the guide rail 34 is horizontally arranged on the inner side of the wall panel 3 and parallel to the length of the container, such as Figure 20As shown, in this embodiment, when the door of the vehicle transport container is opened at one end, the limit mechanisms corresponding to the vehicle transport frames on each layer can refer to the settings of the second embodiment; when the door is opened at both ends, the limit mechanisms corresponding to the vehicle transport frames on each layer can refer to the settings of the first embodiment. In this embodiment, the second-layer frame 4b is placed horizontally on the ground to load the vehicle, and a forklift is required to lift the vehicle transport frame and the vehicle horizontally and send it into the guide rail 34; when the horizontal height of the guide rail 34 is low, the front end of the second-layer frame 4b can also be placed on the end of the guide rail 34, and after the vehicle is loaded, the rear end can be lifted and sent horizontally by a forklift. In the second and third embodiments, when the door is opened at one end, when the vehicle transport frame is out of the box body, the vehicle transport frame close to the box door 2 needs to be removed from the bottom frame or the guide rail 34 before the vehicle transport frame away from the box door 2 can be operated. Based on the above solution, a fourth embodiment can also be provided, in which doors are opened at both ends of the box body, and the style of the guide rail 34 in the second embodiment and the limiting mechanism set when the double-end doors are opened in the first embodiment are adopted. When the second-layer frame 4b enters the third horizontal part 348, the same forklift lifting operation as the third embodiment can be adopted.

[0076] Before a vehicle enters a corresponding vehicle transport rack, it is necessary to determine whether the vehicle height meets the height space range corresponding to the vehicle transport rack. Generally, the vehicle is first parked on the second-layer rack 4b and then loaded onto the first-layer rack 4a.

[0077] In summary, the present invention inherits the length, width and functions of a 40-foot container, but is overall heightened to accommodate taller vehicles. At the same time, the casters on both sides of the transport frame cooperate with the guide rails 34 on the inner side of the chassis 1 or the wall panel to facilitate the smooth entry and exit of the transport frame from the container door, meeting the requirements of securing and transporting four large vehicles such as SUVs. In this structure, the transport frame can extend to the outside of the container, enabling the loading and unloading of vehicles outside the container, increasing the range of vehicle width options; the flipping, self-locking and other fixing mechanisms inside the container eliminate the need for complex transport frame fixing operations. The present invention can make the transport frame's entry and exit operations smoother and the installation operation simpler, thereby enabling multimodal transport and completing transportation tasks quickly and efficiently.

[0078] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
