DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0026] Reference Figure 1-Figure 7The top of the rotating shaft 14 passes through the bottom plate 1 and is fixedly mounted with a worm gear 16. A mounting cavity is provided in the bottom plate 1, and a plurality of mounting openings are provided on the upper surface of the bottom plate 1. A first threaded rod 3 is vertically and rotatably installed in the mounting opening. A first slide 4 is threadedly sleeved on the first threaded rod 3. The upper surface of the first slide 4 is fixedly connected to the lower surface of the top plate 2 through a plurality of connecting rods 5. The plurality of first threaded rods 3 are controlled to rotate together by a transmission assembly. The transmission assembly includes a plurality of first sprockets 12 respectively fixedly sleeved on the plurality of first threaded rods 3 and a chain 13 meshing and wound on the plurality of first sprockets 12. A rotating shaft 14 is vertically and rotatably installed in the mounting cavity, a second sprocket 15 is fixedly sleeved on the rotating shaft 14, and the second sprocket 15 is meshed with one of the first sprockets 12. The top end of the rotating shaft 14 passes through the bottom plate 1 and is fixedly sleeved with a worm gear 16. A placement plate is fixedly mounted on the upper surface of the bottom plate 1, and a worm 17 meshing with the worm gear 16 is rotatably installed on the surface of the placement plate.

[0027] A first mounting opening is horizontally opened on the surface of the bottom plate 1, and a second threaded rod 6 with opposite thread directions at the left and right ends is horizontally rotatably installed in the first mounting opening, a second slide 7 is symmetrically threadedly sleeved on the second threaded rod 6, and a longitudinal clamping plate 8 is fixedly installed on the top of the second slide 7. A second mounting opening is horizontally opened on the lower surface of the top plate 2, and a third threaded rod 9 with opposite thread directions at the left and right ends is horizontally rotatably installed in the second mounting opening, a third slide 10 is symmetrically threadedly sleeved on the third threaded rod 9, and a transverse clamping plate 11 is fixedly installed on the bottom end of the third slide 10, the left and right side walls of the second slide 7 are in sliding contact with the wall of the first mounting opening, and the front and rear surfaces of the third slide 10 are in sliding contact with the wall of the second mounting opening, and servo motors (not shown) are fixedly installed on the surfaces of the bottom plate 1 and the top plate 2, and the output shafts of the two servo motors are fixedly connected to the second threaded rod 6 and the third threaded rod 9, respectively.

[0028] First, place the container to be transported on the upper surface of the bottom plate 1 and between the two longitudinal clamping plates 8. Then start the servo motor located below to control the rotation of the second threaded rod 6, so that the two second slides 7 move horizontally and longitudinally closer to each other until the two longitudinal clamping plates 8 respectively touch the front and rear surfaces of the container. At this time, by rotating the worm 17, the worm wheel 16 engaged with the worm 17 is controlled to rotate with the rotating shaft 14 and the second sprocket 15. At this time, under the transmission action of the multiple first sprockets 12 and the chain 13, the multiple first threaded rods 3 will rotate together, and the multiple first sprockets 12 and the chain 13, which are respectively threaded on the multiple first threaded rods 3, will rotate together. The slide 4 will move vertically with the top plate 2 until the top plate 2 moves to abut against the top of the container, then stop rotating the worm 17, and then start the servo motor located above to control the rotation of the third threaded rod 9, so that the two third slides 10 move laterally relative to each other, until the two horizontal clamping plates 11 respectively abut against the left and right side walls of the container to complete the fixation of the container, and can quickly complete the horizontal, vertical and vertical clamping and fixation of the container, so that the transport rack can be suitable for containers of different heights, widths and lengths, and the multi-directional clamping and fixation of the container improves the fixing effect of the transport rack on the container.

[0029] The upper surface of the bottom plate 1 , the lower surface of the top plate 2 , the surfaces of the transverse clamping plate 11 and the longitudinal clamping plate 8 are all bonded with an anti-slip layer made of rubber.

[0030] The rubber anti-slip layer has good elasticity and viscosity, which can increase the friction between the contact surface of the transport rack and the container, while also avoiding damage to the container surface caused by pressure.

[0031] A fixed plate is symmetrically fixedly installed on the upper surface of the top plate 2, and a rotating rod 18 is installed horizontally and rotatably between the two fixed plates. Two support plates 19 are fixedly installed on the front and rear surfaces of the bottom plate 1 and the top plate 2, and a cross bar 20 is installed horizontally and rotatably between each two support plates 19. A plurality of straps 21 are wrapped around the rotating rod 18, and the ends of the plurality of straps 21 away from the rotating rod 18 are respectively fixedly connected to the surfaces of the two cross bars 20 located below. The two rotating rods 18 are controlled to rotate relative to each other by a driving assembly. The driving assembly includes two gears 22 respectively fixedly sleeved on the two rotating rods 18 and a driving motor 23 fixedly installed on the surface of one of the fixed plates. The output shaft of the driving motor 23 is fixedly connected to one of the rotating rods 18, and the two gears 22 are meshed and connected.

[0032] When the drive motor 23 is started, the two meshing gears 22 will rotate relative to each other, thereby achieving the effect of releasing the two rotating rods 18 and reeling in the straps 21. When the transport rack has completed the fixation of the container, the multiple straps 21 can be controlled to be in a taut state, which can prevent the container from moving out from between the bottom plate 1 and the top plate 2. At the same time, it can also give the bottom plate 1 and the top plate 2 a force that moves closer to each other, further improving the effect of fixing the container.

[0033] The two cross bars 20 located at the top are mainly used to prevent the straps 21 in a taut state from being subjected to a large shear force due to contact with the surface of the top plate 2, which may cause the risk of breakage.

[0034] When the container is loaded, the container is first placed on the upper surface of the bottom plate 1 and placed between the two longitudinal clamping plates 8. Then, the second threaded rod 6 is controlled to rotate so that the two second slides 7 move horizontally and longitudinally closer to each other until the two longitudinal clamping plates 8 respectively abut against the front and rear surfaces of the container. At this time, the plurality of first threaded rods 3 are controlled to rotate together, and the plurality of first slides 4 respectively threadedly sleeved on the plurality of first threaded rods 3 will carry the top plate 2 to move vertically until the top plate 2 moves to abut against the top of the container. Then, the rotation of the worm 17 is stopped, and then the third threaded rod 9 is controlled to rotate so that the two third slides 10 move laterally relative to each other until the two transverse clamping plates 11 respectively abut against the left and right side walls of the container to complete the fixing of the container. The horizontal, longitudinal and vertical clamping and fixing of the container can be quickly completed, so that the transport rack can be suitable for containers of different heights, widths and lengths, and the multi-directional clamping and fixing of the container is improved, thereby improving the fixing effect of the transport rack on the container.

[0035] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
