[0063] The present application provides a double-layer vehicle transport box, which can load two layers of vehicles. Figures 1 to 5As shown, the double-deck vehicle transport box includes a box body 100, which includes a chassis 10 and an intermediate layer 80, both of which can be used to carry vehicles. The chassis 10 and the intermediate layer 80 of the double-deck vehicle transport box 300 can each carry one or more vehicles in the length direction D1 of the box body 100. The intermediate layer 80 is above the chassis 10, and the intermediate layer 80 can move up and down in the height direction D3 of the box body 100. The height direction D3 of the box body 100 is generally in the vertical direction.
[0064] The box body 100 includes two sides in the width direction D2, at least one of which is provided in an open structure, for example, without a side plate, so that at least one side of the box body 100 has space for a forklift to lift and lower the intermediate layer 80. The box body 100 includes two ends in the length direction D1, both of which are provided with an upper door 20 and a lower door 30. The pivot axes of the upper door 20 and the lower door 30 are arranged in the width direction D2, and the lower door 30 is pivotally connected to the chassis 10. The pivot axis of the upper door 20 is above the pivot axis of the lower door 30 in the height direction D3, and the upper door 20 is pivoted upward to open, and the lower door 30 is pivoted downward to open. The side is a structure where the side surface of the box body 100 is generally perpendicular to the width direction D2, and the two sides are arranged in the width direction D2. The end is a structure where the end surface of the box body 100 is generally perpendicular to the length direction D1, and the two ends are arranged in the length direction D1.
[0065] It can be understood that the intermediate layer 80 can be moved upward to a certain height and fixed, that is, at least to the height at which the intermediate layer 80 and the chassis 10 can accommodate vehicles; the intermediate layer 80 can be moved downward to a lowered position, that is, to be close to or contact the upper surface of the chassis 10 and fixed. After the door body of the end is pivoted open, the vehicle can enter the box from any one of the two ends and onto the intermediate layer 80 in the lowered position. The upper door 20 is pivoted upward and outward to open, and the lower door 30 is pivoted downward and outward to open. The upper door 20 and the lower door 30 are pivoted to be generally along the height direction D3, which can be closed and locked.
[0066] In some specific embodiments, the end portion further comprises an upper end wall, which comprises a top end beam 40 and a cross end beam 41. The top end beam 40 and the cross end beam 41 both extend along the width direction D2 of the box 100 and are connected to the corner columns 60 on both sides. The two top end beams 40 are respectively located at both ends of the top of the box 100 in the length direction D1, and the cross end beam 41 is located below the top end beam 40. The upper turnover door 20 is pivotally connected to the cross end beam 41. That is, the pivot shaft of the upper turnover door 20 is located a certain distance below the top end beam 40. It can be understood that the distance from the cross end beam 41 to the base frame 10 is at least greater than the height of the vehicle to be carried. The end portion door is arranged as an up-down door, and the pivot shaft of the upper turnover door 20 is located below the top end beam 40, so that the length of the door body of the upper turnover door 20 and the lower turnover door 30, that is, the size between the free pivot end and the pivotally connected end of the door body, is small, and the opening and closing can still be realized in a narrow space, and the application range is wide.
[0067] Further, the upper end wall further comprises a fixed plate 50, the upper end of the fixed plate 50 is fixedly connected with the top end beam 40, and the lower end of the fixed plate 50 is fixedly connected with the cross end beam 41. That is, the upper part of the end portion of the box 100 can be arranged as a fixed structure through the fixed plate 50.
[0068] The end portion of the transport frame 100 further comprises a corner column 60, which extends along the height direction D3. Specifically, the corner column 60 is located at the connection between the side portion and the end portion of the box 100, and two corner columns 60 are arranged at each end portion, that is, one corner column 60 is arranged at each corner of the box 100.
[0069] In order to enable the upper turnover door 20 to remain in the open state after being opened, as shown in Figure 2 The fixed plate 50 is provided with a first fixing member 51, and the upper turnover door 20 is provided with a first connecting member 21, which is detachably connected with the first fixing member 51. For example, the first fixing member 51 is a hook or a fixed ring, and the first connecting member 21 is a rope, a steel wire or the like. The structure of the first connecting member 21 and the first fixing member 51 is arranged to be detachably connected and can provide a pulling force sufficient to keep the upper turnover door 20 in the open state, and is not specifically limited.
[0070] In order to enable the lower turnover door 30 to stop rotating after being pivoted to a certain angle (for example, to be substantially horizontal), as shown in Figure 4As shown, the second fixing member 61 can be arranged on the corner column 60, and the second connecting member 31 is arranged on the lower turnover door 30 and detachably connected with the second fixing member 61. For example, the second fixing member 61 is a hook or a fixing ring, and the second connecting member 31 is a rope or a steel wire. The structure of the second connecting member 31 and the second fixing member 61 is detachably connected and can provide a pulling force sufficient to maintain the state of the lower turnover door 30, without specific limitation. Thus, the lower turnover door 30 can be subjected to an upward pulling force after being opened, can withstand a certain downward pressure and maintain its pivoted state. In addition, when the double-layer vehicle box 300 is used for railway transportation, the lower turnover door 30 can be pivoted to be supported by the railway vehicle after being opened, serving as a deck between adjacent double-layer vehicle boxes 300 to support the direct driving of the vehicle through different box bodies.
[0071] The side part arranged in the open structure is further provided with a side column 70 extending along the height direction D3. In order to fix the intermediate layered shelf 80 to a certain height, the side column 70 is provided with a limiting hole, and the side part of the intermediate layered shelf 80 has a limiting pin matched with the limiting hole. Alternatively, the limiting pin is detachable with the intermediate layered shelf 80. Preferably, the side column 70 is provided with a plurality of limiting holes spaced apart along the height direction D3, and the intermediate layered shelf 80 can be fixed to different heights. At the same time, the corner column 60 can also be provided with a limiting hole, which is used together with the limiting hole of the side column 70 to fix the intermediate layered shelf 80.
[0072] In some specific embodiments, the top of the box body 100 is open. Preferably, the box body 100 further comprises a top cross beam 42. The top cross beam 42 is located at the top of the box body 100, extends along the width direction D2, and is connected to the two side parts of the box body 100 at both ends, so as to strengthen the structural strength of the top of the box body 100.
[0073] As shown, Figure 7 The double-layer vehicle box 300 further comprises a curtain 200. The curtain 200 covers the top of the box body 100. As shown, Figure 6 The top of the box body 100 is provided with a curtain support frame 210 for supporting the curtain 200. The curtain 200 can also be used to cover at least one of the two side parts.
[0074] Further, the side part of the box body 100 further comprises a telescopic column 90, which comprises a hollow fixed column 91 located at the bottom, and a movable column 92 inserted into the inner cavity of the fixed column 91. The movable column 92 can move up and down relative to the fixed column 91, and is positioned between the movable column 92 and the fixed column 91 by a fixed pin, so that the height of the movable column 92 is fixed. The arrangement of the telescopic column 90 increases the height space for loading the vehicle in the double-layer vehicle box 300, and through the length of the telescopic column 90, the hoisting and stacking operations of the box body are satisfied. In railway transportation, the telescopic column 90 is retracted to meet the gauge size requirements of the railway.
[0075] The process of loading the double-layered vehicle box 300 with a car according to the present application is, for example, as follows: the side curtain 200 is opened; the forklift lowers the middle layered shelf 80 from the side of the box and places it on the bottom shelf 10; the upper and lower end doors 20 and 30 are opened; the car is opened into the middle layered shelf 80 in the box from the end door, sequentially, and is fixed with the middle layered shelf 80 (as shown in FIG. 5); the forklift raises the middle layered shelf 80 from the side of the box to the loading position, and fixes the middle layered shelf 80; the lower car is opened into the bottom shelf 10 in the box from the end door, sequentially, and is fixed with the bottom shelf 10; the side curtain 200 is closed; and the end door is closed. If the height does not exceed the height of the normal corner piece, the telescopic column 90 is not opened. If the height exceeds the height of the normal corner piece, the telescopic column 90 is adjusted to the highest position. Figure 5
