A plurality of cargo box pallets 4 evenly distributed from top to bottom are fixedly installed between the four hollow steel frame columns 2, and a three-sided retaining frame 5 is fixedly installed on the top of the cargo box pallet 4. A plurality of transport cargo boxes 6 are respectively placed between any two adjacent cargo box pallets 4, as shown in FIG. Figure 7 As shown, the bottom of the transport container 6 is fixedly sleeved with a positioning sleeve 25 adapted to the three-sided retaining frame 5, as shown in FIG. Figure 4 As shown, one side of the plurality of cargo box pallets 4 is rotatably mounted with a same transmission rotating rod 7, as shown in FIG. Figure 1 As shown, the other side of the plurality of cargo box pallets 4 is fixedly mounted with the same slide bar 8, as shown in FIG. Figure 5 As shown, the transmission rotating rod 7 is provided with a plurality of evenly distributed thread grooves 701, the transmission rotating rod 7 is threadedly connected with a plurality of lifting screw sleeves 9 through the thread grooves 701, the sliding rod 8 is slidably connected with a plurality of lifting sleeves, and a positioning cover 10 adapted to the transport container 6 is fixedly installed between the lifting screw sleeves 9 and the lifting sleeves at the same height, as shown in FIG.

Figure 3 As shown, an extruded top plate 13 is placed on the top of the uppermost cargo box pallet 4. Figure 6As shown, a spring telescopic plate 14 is slidably installed on the top of the extruded top plate 13. In this embodiment, except for the topmost cargo box pallet 4, each layer of cargo box pallets 4 is placed with a transport cargo box 6, and the topmost cargo box pallet 4 is placed with an extruded top plate 13. A slide groove is opened on the top of the extruded top plate 13, and a spring telescopic plate 14 is slidably installed inside. Elastic parts such as springs and spring rods are arranged between the spring telescopic plate 14 and the extruded top plate 13, so that the spring telescopic plate 14 can be elastically telescopic on the top of the extruded top plate 13, and one side of the extruded top plate 13 is fixedly installed A driving rack 15 is provided which is compatible with the transmission gear 12; specifically, when the dangerous logistics transport rack is in use, the first row of multiple shelf components are pushed into the multiple double-track guide rails 1 in sequence, so that the shelf components are moved to the innermost side of the transport compartment along the double-track guide rails 1 with the help of the guide wheels 3 at the bottom, and then the first batch of transport containers 6 loaded with dangerous goods are placed on each layer of container pallets 4 in sequence, and the side walls of the positioning sleeves 25 at the bottom of the transport containers 6 are tightly attached to the inner side of the three-sided blocking frame 5, and then the multiple extruded top plates 13 are sent to the same level as the uppermost container pallet 4 in sequence. At this time, the top of the spring telescopic plate 14 contacts the top inner wall of the compartment, so that the spring telescopic plate 14 contracts toward the inside of the extruded top plate 13, and then the extruded top plate 13 is gradually pushed into between the topmost cargo box pallet 4 and the compartment roof, so that the extruded top plate 13 is stuck in the middle to limit the entire shelf assembly. At the same time, in the process of pushing the extruded top plate 13, the driving rack 15 on one side of the extruded top plate 13 will gradually contact the transmission gear 12 and drive the transmission gear 12 to rotate, thereby driving the transmission rotating rod 7 to rotate multiple circles through the transmission shaft 11, so that the lifting screw sleeve 9 The sliding sleeve drives the middle positioning cover 10 to descend until multiple positioning covers 10 are synchronously buckled on the top of the flip cover of each transport box 6, thereby positioning each transport box 6 to prevent the transport box 6 from sliding off the shelf assembly during transportation. The above operation is then repeated to place each row of shelf assemblies on the top of the double-track guide rail 1 in turn, so that the shelf assemblies contact each other and are stacked inside the carriage. When unloading, the extrusion top plate 13 can be removed to release the limit on the transport box 6, thereby realizing rapid positioning and placement of the transport box 6 and the shelf assembly.

[0037] like Figure 4 , Figure 5As shown, two supporting rotating frames 16 are fixedly installed on the top of the positioning cover 10, and the same horizontally arranged double-headed rotating rod 17 is rotatably installed on the two supporting rotating frames 16. In this embodiment, the double-headed rotating rod 17 is perpendicular to the double-track guide rail 1, that is, the double-headed rotating rod 17 is perpendicular to the moving track of the shelf assembly on the double-track guide rail 1, and the two ends of the double-headed rotating rod 17 are fixedly installed with pitch-adjusting screws 18. The two pitch-adjusting screws 18 are symmetrically arranged and are both screwed with docking screw sleeves 19. The two sides of the docking screw sleeves 19 are fixedly installed with docking extrusion plates 20. The bottoms of the docking extrusion plates 20 are in contact with the top of the positioning cover 10. The transmission rotating rod 7 and the sliding rod 8 are separated. Specifically, by arranging the butt-extrusion plates 20, after the first row of shelf components is fixed, the double-headed rotating rods 17 on the top of the positioning covers 10 of each layer are rotated in sequence, so that the distance-adjusting screws 18 at both ends drive a total of four butt-extrusion plates 20 to move toward both sides respectively through the butt-extrusion sleeves 19, so that the butt-extrusion plates 20 on adjacent shelf components are in contact with and pressed against each other, and the butt-extrusion plates 20 at the outermost ends are pressed against the inner wall of the carriage, so that the gaps between the shelf components in the first row and the gaps with the carriage are supported by the butt-extrusion plates 20, effectively preventing the shelf components from shaking violently during the process.

[0038] like Figure 6 As shown, two "J"-shaped slides 21 are arranged on the top of the extrusion top plate 13, and the two "J"-shaped slides 21 are respectively located on both sides of the spring telescopic plate 14, and the four corners of the extrusion top plate 13 are fixedly installed with vertically arranged positioning sleeves 22, and both ends of the two "J"-shaped slides 21 are slidably installed inside the four positioning sleeves 22, and the two bottom ends of the "J"-shaped slides 21 are fixedly installed with positioning rods 23, as shown in FIG. Figure 4 As shown, the four corners of the top of the cargo box pallet 4 located at the top are provided with positioning holes 401 compatible with the positioning rods 23; specifically, by providing an I-shaped slide 21, after the extruded top plate 13 is inserted between the top cargo box pallet 4 and the top of the car body, the I-shaped slide 21 can be slid so that the positioning rods 23 at its bottom are respectively inserted into the respective positioning holes 401 on the top of the cargo box pallet 4, so that the extruded top plate 13 is fixed to the top of the shelf assembly under the clamping action of the positioning rods 23 and the elastic extrusion action of the spring telescopic plate 14 without slipping, thereby ensuring that there is sufficient acting pressure between the shelf assembly and the car body, and when removing the extruded top plate 13, the I-shaped slide 21 can also provide a convenient gripping area for the staff.

[0039] like Figure 6As shown, two supporting sliders 24 are slidably installed on the top of the extruded top plate 13, and the positions of the two supporting sliders 24 correspond to the positions of the two "X"-shaped slides 21 respectively; specifically, by setting the supporting sliders 24, when the extruded top plate 13 is inserted between the cargo box pallet 4 and the car roof, the "X"-shaped slide 21 can be slid upward in advance, and then the corresponding supporting slider 24 can be slid to the bottom of the "X"-shaped slide 21, so that the supporting slider 24 supports the "X"-shaped slide 21 to prevent the "X"-shaped slide 21 from driving the positioning rod 23 to slide down by itself during the insertion of the extruded top plate 13, thereby affecting the installation process of the extruded top plate 13. After the installation of the extruded top plate 13 is completed, the supporting slider 24 can be reset to make the "X"-shaped slide 21 slide down again to position the extruded top plate 13.

[0040] like Figure 7 As shown, a plurality of cotton placing boards 26 stacked from top to bottom are placed inside the transport box 6. In the present embodiment, each layer of cotton placing boards 26 is provided with placement holes for placing dangerous goods storage containers. Specifically, by providing the cotton placing boards 26, storage containers loaded with dangerous goods can be placed in the interior of the multiple layers of cotton placing boards 26 in sequence, so that the cotton placing boards 26 are located between the transport boxes 6 to provide buffering and shock absorption for the containers.

[0041] like Figure 8 As shown, adjacent surfaces of multiple cotton boards 26 are provided with grid grooves, and the same grid steel frame 27 is placed inside two grid grooves located at the same place. In this embodiment, the grid aperture size on the grid steel frame 27 matches the aperture size of the placement hole on the cotton board 26; specifically, by setting the grid steel frame 27, the grid steel frame 27 can be located inside the transport cargo box 6 to play a rigid support role for the cotton boards 26 and storage containers loaded with dangerous goods, thereby enhancing the shock-absorbing effect of the cotton boards 26 and reducing the shaking amplitude of the container inside the cotton boards 26.

[0042] like Figure 8 As shown, multiple front ends of the grid steel frame 27 extend to the outside of the grid groove and are fixedly installed with abutment plates 28, and the abutment plates 28 are in contact with the inner walls of the transport box 6; specifically, by setting the abutment plates 28, the front ends of the grid steel frame 27 are tightly attached to the inner walls of the transport box 6 through the abutment plates 28, so that the external pressure on the transport box 6 is transmitted to the shelf assembly through the grid steel frame 27 without affecting the internal container.

[0043] like Figure 2 As shown, both ends of the double-track guide rail 1 are provided with a locking groove 101. Figure 1As shown, the positioning slots 101 are all connected with positioning baffles 29; specifically, by setting the positioning baffles 29, before placing the first row of shelf components, the positioning baffles 29 are first connected to the innermost positioning slots 101, and then the multiple shelf components are fixed together with the transport container 6 in the interior of the carriage in turn, and finally the second positioning baffle 29 is connected to the outermost positioning slots 101, so that the front and rear positioning baffles 29 play a role of limiting the multiple shelf components, and cooperate with the carriage and the door to ensure the stability and safety of the shelf components and the transport container 6 during transportation.

[0044] In summary: when the hazardous logistics transport rack is in use, the multiple shelf components of the first row are first pushed into the multiple double-track guide rails 1 in turn, so that the shelf components are moved to the innermost side of the transport carriage along the double-track guide rails 1 with the help of the guide wheels 3 at the bottom, and then the first batch of transport boxes 6 loaded with hazardous goods are placed on each layer of the box pallet 4 in turn, and the side wall of the positioning sleeve 25 at the bottom of the transport box 6 is made to fit tightly with the inner side of the three-sided retaining frame 5, and then multiple extruded top plates 13 are sent to the same height as the topmost box pallet 4 in turn. At this time, the top of the spring telescopic plate 14 contacts the top inner wall of the carriage, so that the spring telescopic plate 14 contracts toward the inside of the extruded top plate 13, and then the extruded top plate 13 is gradually pushed between the topmost box pallet 4 and the top of the carriage, so that the extruded top plate 13 is stuck in the middle to align the whole The rack components are limited in position. At the same time, in the process of pushing in the extrusion top plate 13, the driving rack 15 on one side of the extrusion top plate 13 will gradually contact the transmission gear 12 and drive the transmission gear 12 to rotate, thereby driving the transmission rotating rod 7 to rotate multiple circles through the transmission shaft 11, so that the lifting screw sleeve 9 and the sliding sleeve drive the middle positioning cover 10 to descend, until multiple positioning covers 10 are synchronously buckled on the top of the flip cover of each transport container 6, thereby positioning each transport container 6 to prevent the transport container 6 from sliding off the rack component during transportation, and then repeat the above operation to place each row of rack components on the top of the double-track guide rail 1 in turn, so that the rack components are in contact with each other and stacked inside the carriage. When unloading, the extrusion top plate 13 is removed to release the positioning of the transport container 6. The limit is realized to realize the rapid positioning and picking and placing of the transport cargo box 6 and the shelf assembly. By setting the docking extrusion plate 20, after the first row of shelf assemblies are fixed, the double-headed rotating rods 17 on the top of each layer of positioning cover 10 are rotated in sequence, so that the distance adjustment screws 18 at both ends drive a total of four docking extrusion plates 20 to move to both sides respectively through the docking screw sleeves 19, so that the docking extrusion plates 20 on adjacent shelf assemblies are in contact with each other and pressed against each other, and the docking extrusion plates 20 at the outermost ends are pressed against the inner wall of the carriage, so that the gaps between the shelf assemblies in the first row and the gaps with the carriage are supported by the docking extrusion plates 20, which effectively prevents the shelf assemblies from shaking violently during the process. By setting the "J"-shaped slide 21, when the extrusion top plate 13 is inserted into the uppermost cargo box After the support plate 4 is between the car body top, the "X"-shaped slide 21 can be slid so that the positioning rods 23 at the bottom ends thereof are respectively inserted into the positioning holes 401 at the top of the cargo box support plate 4, so that the extruded top plate 13 is fixed to the top of the shelf assembly under the action of the clamping of the positioning rods 23 and the elastic extrusion of the spring telescopic plate 14 without slipping, thereby ensuring that there is sufficient acting pressure between the shelf assembly and the car body. When removing the extruded top plate 13, the "X"-shaped slide 21 can also provide a convenient gripping area for the staff. By providing the supporting slider 24, when the extruded top plate 13 is inserted between the cargo box support plate 4 and the car body top, the "X"-shaped slide 21 can be slid upward in advance, and then the corresponding supporting slider 24 can be slid to the bottom of the "X"-shaped slide 21.The supporting slider 24 is used to support the "X"-shaped slide 21 to prevent the "X"-shaped slide 21 from driving the positioning rod 23 to slide down by itself during the process of inserting the extrusion top plate 13, thereby affecting the installation process of the extrusion top plate 13. After the installation of the extrusion top plate 13 is completed, the supporting slider 24 is reset to allow the "X"-shaped slide 21 to slide down again to position the extrusion top plate 13. By arranging the cotton placement board 26, the storage container loaded with dangerous goods can be placed in the interior of the multi-layer cotton placement board 26 in sequence, so that the cotton placement board 26 is located between the transport box 6 to play a buffering and shock-absorbing role for the container. By arranging the grid steel frame 27, the grid steel frame 27 can be located inside the transport box 6 to play a rigid support role for the cotton placement board 26 and the storage container loaded with dangerous goods, thereby enhancing the shock-absorbing effect of the cotton placement board 26 and reducing the container. The swing amplitude inside the cotton board 26 is placed. By setting the abutment plate 28, each front end of the grid steel frame 27 is tightly attached to each inner wall of the transport box 6 through the abutment plate 28, so that the external pressure on the transport box 6 is transmitted to the shelf assembly through the grid steel frame 27 without affecting the internal container. By setting the positioning baffle 29, before placing the first row of shelf assemblies, the positioning baffle 29 is first plugged into the innermost slot 101, and then multiple shelf assemblies are fixed together with the transport box 6 in the interior of the carriage in sequence, and finally the second positioning baffle 29 is plugged into the outermost slot 101, so that the front and rear two positioning baffles 29 play a role in limiting the multiple shelf assemblies, and cooperate with the carriage and the door to ensure the stability and safety of the shelf assembly and the transport box 6 during transportation.
