[0002] With the continuous development of global trade, container transportation has become an indispensable part of international logistics. As an important tool for container transportation, the design and function of container wide-gauge flat cars are crucial to improving transportation efficiency and reducing costs. Traditional export container wide-gauge flat cars are mainly used to transport two groups of containers of the same size.

[0032] It should be noted that the bottom of the support frame 34 is overlapped on the top of the lower container, thereby effectively supporting the bottom of the support frame 34.

[0033] It should also be noted that the top of the support frame 31 and the top of the support frame 34 are respectively provided with sliding grooves for facilitating the sliding of the support frame 34 and the upper container locking mechanism 4 .

[0034] Specifically, when in use, the lower container is lifted to the top of the wide-gauge flat car body 1.

A hydraulic station (not shown in the figure) is provided on the wide-gauge flat car body 1 for supplying oil to the hydraulic telescopic rod 313.

[0037] Specifically, the hydraulic telescopic rod 313 is controlled to operate, and the operation of the hydraulic telescopic rod 313 drives its output end to extend, and the extension of the output end synchronously drives the side adjustment bracket 312 to flip outward with the top of the mountain-shaped main frame 311 as the center, so as to facilitate the placement of the lower container from the side, and the use effect is good.

[0038] In one embodiment of the present invention, Figure 3-Figure 4As shown, the support frame 31 also includes a screw fixing mechanism 6, which includes a bidirectional threaded screw 61, a first bevel gear 62, a limiting column 63, a connecting screw 64, a connecting tube 65, a synchronization rod 66, a second bevel gear 67, a third bevel gear 68, a driving rod 69, a fourth bevel gear 610, a fifth bevel gear 611 and a first adjustment handle 612, wherein the bidirectional threaded screw 61 is symmetrically rotatably connected to the inner wall of the mountain-shaped main frame 311, the first bevel gear 62 is fixedly connected to the center of the surface of the bidirectional threaded screw 61, the limiting column 63 is symmetrically threadedly connected to the outer surface of the bidirectional threaded screw 61, and is horizontally slidably connected to the inner wall of the mountain-shaped main frame 311, the connecting screw 64 is fixedly connected to the outer surface of the limiting column 63, the connecting tube 65 is threadedly connected to the surface of the side adjustment bracket 312, and corresponds to the position of the connecting screw 64, and one end of the connecting screw 64 passes through the mountain-shaped main frame 311. The main frame 311 is outside and is threadedly connected to the inner wall of the connecting tube 65. The synchronization rod 66 is symmetrically connected to the inner wall of the mountain-shaped main frame 311 and is located on one side of the bottom of the bidirectional threaded screw 61.

The other end of the synchronization rod 66 is fixedly connected to the third bevel gear 68. The driving rod 69 is rotatably connected to the inner wall of the mountain-shaped main frame 311 and is located on one side of the third bevel gear 68. The fourth bevel gear 610 is evenly fixedly connected to the surface of the driving rod 69 and meshes with the third bevel gear 68. The fifth bevel gear 611 is rotatably connected to the inner wall of the mountain-shaped main frame 311 and meshes with one group of the fourth bevel gears 610. The first adjusting handle 612 is rotatably connected to the surface of the mountain-shaped main frame 311 and is fixedly connected to one end of the central axis of the fifth bevel gear 611.

The rotation of the fourth bevel gear 610 synchronously drives the third bevel gear 68, the synchronization rod 66 and the second bevel gear 67 to rotate. The rotation of the second bevel gear 67 synchronously drives the first bevel gear 62 to rotate. The rotation of the first bevel gear 62 synchronously drives the bidirectional threaded screw 61 to rotate. The rotation of the bidirectional threaded screw 61 synchronously drives the limiting column 63 and the connecting screw 64 to move horizontally outward. After the connecting screw 64 moves horizontally, one end of it passes through the outside of the mountain-shaped main frame 311. Then the connecting cylinder 65 is rotated so that it is threadedly connected to the outer surface of the connecting screw 64, so that the mountain-shaped main frame 311 can be connected to the side adjustment bracket 312, and the use effect is good.

[0042] Specifically, the screw adjustment mechanism 7 is provided to facilitate the adjustment of the position of the upper container locking mechanism 4, thereby improving the operating efficiency. The second adjustment handle 74 is rotated, and the second adjustment handle 74 rotates synchronously to drive the seventh bevel gear 73 to rotate. The seventh bevel gear 73 rotates synchronously to drive the sixth bevel gear 72 and the one-way threaded screw 71 to rotate. The one-way threaded screw 71 rotates synchronously to drive the upper container locking mechanism 4 to move horizontally along the top of the support frame 34, and the use effect is good.

[0043] In one embodiment of the present invention, Figure 5 As shown, the screw adjustment mechanism 7 also includes a scale line (not shown in the figure) arranged on the top of the support frame 34.

[0044] It should be noted that the scale line design described in this embodiment facilitates timely knowing whether the position of the upper container locking mechanism 4 is accurate, and has a good use effect.

[0047] Specifically, when in use, hold the handle 88 and then rotate it.
