[0021] The present utility model discloses a container with liftable casters. Refer to Figures 1 to 4。The underframe of a general container includes bottom crossbeams 2, bottom side beams 3, bottom corner fittings, and a floor 1. The floor 1 is laid on multiple parallel bottom crossbeams 2. Bottom side beams 3 are fixed on both sides of the bottom crossbeams 2. The bottom corner fittings are the four top corners of the underframe. Under normal circumstances, the corner fittings are in direct contact with the ground, and neither the bottom side beams 3 nor the bottom crossbeams 2 are in contact with the ground. There is a certain available space between the bottom side beam 3 above the floor 1 and the ground.
[0022] The utility model utilizes the available space between the floor 1 and the ground to install a liftable caster device. The liftable caster device includes an adjusting device 4 and a caster 5 arranged at the output end of the adjusting device 4. Operating the adjusting device 4 can lift and lower the corresponding caster 5. For specific embodiments, reference can be made to Figures 3 to 7 。
[0023] Four adjusting devices 4 are fixed to the bottom surface of the floor 1. Every two form a group. Each group of adjusting devices 4 is respectively close to the same bottom side beam 3, and each adjusting device 4 is respectively located between a group of adjacent bottom crossbeams 2.
[0024] Each adjusting device 4 includes a fixing plate 41, an adjusting screw 42, a support top seat 43, and a caster support 44. For reference, see Figure 5 。The fixing plate 41 is fixed to the bottom surface of the floor 1. The adjusting screw 42 is vertically arranged. One end of the adjusting screw 42 is connected to the fixing plate 41 by a bearing, and the other end is threadedly connected to the support top seat 43. That is, the adjusting screw 42 can only rotate around the axis relative to the fixing plate 41 and cannot move axially. An adjusting ring 45 is fixed on the adjusting screw 42. The adjusting ring 45 is located between the fixing plate 41 and the support top seat 43. Operating the adjusting ring 45 can rotate the adjusting screw 42.
[0025] The caster support 44 is horizontally arranged as a whole. One end is connected to the support top seat 43 by a bearing, and the other end is hinged with a caster 5. The axis of the caster 5 is a horizontal axis. That is, there is no relative movement in the vertical direction between the caster support 44 and the support top seat 43. The caster support 44 moves up and down following the support top seat 43; and when there is no external force, the caster support 44 can rotate in any direction around its bearing connection with the support top seat 43 in the horizontal direction, but the rotation amplitude and range are limited by the adjacent bottom side beam and bottom crossbeam.
[0026] A limiting block 46 is fixed to the horizontal side of the support top seat 43. A vertical limiting groove 32 corresponding to the limiting block 46 is arranged on the side of the bottom side beam 3 facing the adjusting device 4. For reference, see Figure 6 and Figure 7 , the limiting groove 32 is formed by two vertically parallel positioning blocks 33. The positioning blocks 33 are fixed to the same positioning plate 34. The positioning plate 34 is welded to the inner side of the bottom side beam 3. The installation of the limiting groove 32 does not require adjusting the structure of the bottom side beam 3 itself, and at the same time, the strength of the bottom side beam 3 can be further enhanced through the positioning plate 34.
[0027] To facilitate the lifting of the caster 5 outside the box, an adjustment hole 31 is provided in the bottom side beam 3. The adjustment hole 31 is directly above the positioning plate 34, and the adjustment ring 45 is aligned with the adjustment hole 31. In combination with Figure 3 , a tool can be used to pass through the adjustment hole 31 to operate the adjustment ring 45, thereby rotating the adjustment screw 42. When the adjustment screw 42 is rotated, the limit groove 32 acts on the limit block 46, so that the support top seat 43 can only move up and down along the limit groove 32 and cannot rotate, thus realizing the lifting of the caster 5. And during the lifting process of the caster 5, a part of the limit block 46 always remains in the limit groove 32, that is, it is ensured that no matter when the adjustment ring 45 is rotated, the support top seat 43 can move up and down.
[0028] During the lifting process of the caster 5, the caster 5 has two position states: suspended or landed.
[0029] Caster 5 suspended: Under normal circumstances, the caster 5 and the adjustment device 4 are hidden between two adjacent bottom cross beams 2. The caster 5 is above the bottom plane of the container and is suspended from the ground, without affecting the normal use of the container.
[0030] Caster 5 landed: When the container needs to be moved, the four casters 5 can be almost simultaneously lowered by operating the four adjustment devices 4 to lift the box body of the container, so that the casters 5 are in contact with the ground while the container is suspended from the ground. At this time, the container is in a movable state. After moving to the position, the casters 5 can be raised to restore to the initial state.
[0031] It should be noted that the model and load-bearing capacity of the caster 5 need to be adjusted according to the self-weight of the container and the mass of the goods in the box. To facilitate the overall installation of the liftable caster device, the entire device is fixed to a cover plate 6. The cover plate 6 is located at the top of the adjustment device 4. The fixing plate 41 is welded to the bottom side of the cover plate 6. The top side of the cover plate 6 is parallel to the floor 1 and is welded to the bottom surface of the floor 1 and the inner side of the bottom side beam 3. When installing the liftable caster 5, only need to control the two sides of the cover plate 6 to abut against the adjacent bottom cross beams 2. The presence of the cover plate 6 strengthens the connection strength between the adjustment device 4 and the bottom side beam 3 and the floor 1, making the overall structure more stable.
[0032] In summary, the utility model utilizes the space from the floor 1 to the ground, installs multiple liftable casters 5 at the bottom of the container, so that the casters 5 are suspended or landed. When the casters 5 are suspended, it does not affect the normal use of the container. When the casters 5 are landed, they can support the box body of the container, making the movement of the container not rely on external equipment.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
