Description

Technical Field

[0001] The present application generally relates to the technical field of container structures, and more particularly to a lifting frame and a container. Background Art

[0002] As people's lives improve, household cars are becoming more and more popular, and automobile import and export trade is increasing day by day. The containerized multimodal transport mode is currently the most widely used freight mode in the world with the best cost cycle, which can effectively achieve the goals of reducing costs, saving energy and reducing emissions, and improving time efficiency.

[0003] When transporting cars in containers, the space utilization rate of the containers should be increased as much as possible. For example, a bracket is set inside the box, and the bracket is used to divide the internal space of the box into two layers, each of which can carry a vehicle. When the bracket is designed to be able to move up and down, when the bracket rises to the middle of the box, it is also necessary to fix the bracket in this position to facilitate loading another vehicle under the bracket. Existing transport brackets often require additional auxiliary equipment such as forklifts, power sources (gas sources, power sources, etc.) to intervene during lifting, which is inconvenient and not conducive to subsequent maintenance; in addition, the synchronization of the bracket during lifting is poor, which is not conducive to the smooth movement of the bracket carrying the vehicle, and there are certain safety hazards.

[0120] The present application provides a lifting frame.

[0121] First embodiment

[0122] See also Figure 1 and Figure 2 , the lifting frame 11 is used for the container 1, or in other words, the lifting frame 11 is installed to the container 1. Specifically, the lifting frame 11 includes a bracket 12 and a lifting device 13, and the bracket 12 is used to carry goods, such as a vehicle. The lifting device 13 is used to drive the bracket 12 to move along the vertical direction DH, and at least two lifting devices 13 are arranged at intervals on both sides of the bracket 12 along the length direction DL or the width direction DW of the container 1. Further, the lifting device 13 includes a bracket 16, a driving assembly 17, a driven member 14 and a transmission assembly 15. The bracket 16 is used to be connected to the container 1. The driving assembly 17 is connected to the bracket 16. The driven member 14 is movably connected to the driving assembly 17. The transmission assembly 15 is connected to the driven member 14 and the bracket 12, so that the driven member 14 drives the bracket 12 to move along the vertical direction DH.

[0123] According to the lifting frame 11 of the present application, the lifting devices 13 located on both sides of the bracket 12 can drive the bracket 12 to rise and fall, while ensuring that the bracket drives the goods to move in an orderly manner along the vertical direction, and optimizing the layout of the lifting devices 13 relative to the bracket 12.

[0124] It should be noted that Figure 1 In the embodiment, two lifting devices 13 are arranged at intervals on both sides of the bracket 12 along the length direction DL of the container 1. In an embodiment not shown, the two lifting devices may also be arranged at intervals on both sides of the bracket 12 along the width direction DW of the container 1. This embodiment is described by assuming that the two lifting devices 13 are arranged at intervals on both sides of the bracket 12 along the length direction DL of the container 1. Figure 2 and Figure 3 , the driving assembly 17 includes a reducer 171, and the lifting device 13 also includes a screw 172. The reducer 171 has an input end 171a and an output end, and the input end 171a is used to connect to an external power source. One end of the screw 172 is connected to the output end of the reducer 171, and the end of the screw 172 away from the reducer 171 is connected to the bracket 16; the driven member 14 is connected to the screw 172 and moves along the screw 172. Due to the diverse use environments of the container 1, the site may not have conditions such as a forklift, power supply, and air source. The reducer 171 can be driven by a tool such as an electric wrench. For example, a charging wrench, a plug-in wrench, etc. The electric wrench is connected to the input end 171a of the reducer 171, and the input end 171a can be constructed as a hexagonal protrusion or groove. Starting the electric wrench drives the reducer 171 to operate, so that the lifting devices 13 adjacent to each other along the length direction or width direction of the container 1 operate synchronously to ensure the smoothness of the lifting of the bracket 12. Such configuration enables the container 1 to have better environmental adaptability and lower maintenance difficulty. Figures 1 to 3 In the embodiment, the screw rod 172 is arranged along the vertical direction DH, one end of the screw rod 172 is connected to the output end of the reducer 171, and one end of the screw rod 172 away from the reducer 171 is connected to the bracket 16. The driven member 14 is movably connected to the screw rod 172 along the vertical direction DH.

[0125] Furthermore, the bracket 16 has a slide groove 16a, the extension direction of the slide groove 16a is consistent with the setting direction of the screw rod 172, and the driven member 14 is at least partially connected to the slide groove 16a. Figure 2 and Figure 3 In the embodiment, the bracket 16 has a slide groove 16a arranged along the vertical direction DH, and the driven member 14 is at least partially connected to the slide groove 16a, so that the driven member 14 will not deviate relative to the horizontal direction, ensuring the movement accuracy of the driven member 14 along the vertical direction DH. The bracket 16 is, for example, made of C-shaped steel, which can be directly used as the slide groove 16a because it has an opening, or the slide groove 16a suitable for the driven member 14 can be formed by simple processing, which reduces the processing difficulty of the slide groove 16a.

[0126] See also Figure 4The input end 171a is configured as a hexagonal protrusion, and accordingly, the electric wrench adapted thereto should have a hexagonal sleeve (groove) adapted thereto. The driven member 14 includes a slider 14a and a screw nut 14b, the screw nut 14b being connected to the slider 14a and protruding upward from the slider 14a. The slider 14a is at least partially disposed in the slide groove 16a, and the screw nut 14b is adapted to the screw 172 and is transmission-connected to the screw 172.

[0127] Return to Reference Figures 1 to 3 The transmission assembly 15 includes a first guide wheel 151, a first transmission member 152, a second guide wheel 153 and a second transmission member 154. Specifically, the first guide wheel 151 is pivotally connected to the bracket 16, and the first guide wheel 151 is located above the driven member 14. One end of the first transmission member 152 is connected to the driven member 14, the first transmission member 152 bypasses the first guide wheel 151 and the other end is connected to the bracket 12. The second guide wheel 153 is pivotally connected to the bracket 16, the second guide wheels 153 are arranged in pairs, and the adjacent second guide wheels 153 are arranged at intervals in the horizontal direction. One end of the second transmission member 154 is connected to the driven member 14, the second transmission member 154 bypasses the adjacent second guide wheels 153 in the horizontal direction in sequence and the other end is connected to the bracket 12.

[0128] It should be noted that the guide wheels (ie, the first guide wheel 151 and the second guide wheel 153 ) have slots, and the transmission components (ie, the first transmission component 152 and the second transmission component 154 ) are arranged around the slots to prevent the transmission components from slipping relative to the guide wheels. Figure 1 In the embodiment, the transmission member is constructed as an iron chain, and the free end of the iron chain is equipped with a lifting lug, which is convenient for passing through the driven member 14 and the bracket 12 and locking them. Figures 1 to 3 , the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are spaced apart along the width direction DW of the container 1. Preferably, as Figure 1 As shown, the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are located on different sides of the bracket 12. It can be understood that the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are preferably located on the same horizontal line along the width direction DW of the container 1 to ensure that the bracket 12 is subjected to balanced forces. Figure 1In the embodiment, the first guide wheel 151 is pivotally connected to the bracket 16 about the width direction DW of the container 1. Since one of the second guide wheels 153 is spaced apart from the first guide wheel 151 along the length direction DL of the container 1, in order to ensure that the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are located on the same horizontal line, the pivot axis direction of the second guide wheel 153 is inclined at a certain angle relative to the length direction DL and / or the width direction DW of the container 1.

[0129] Alternatively, see Figure 5 , the screw rod 172 is arranged along the first horizontal direction D1. Specifically, the screw rods 172 are arranged in pairs, and adjacent screw rods 172 are spaced along the second horizontal direction D2, and the first horizontal direction D1 is perpendicular to the second horizontal direction D2. The driven member 14 is movably connected to the screw rod 172 along the first horizontal direction D1. The first guide wheels 151 are arranged in pairs, and adjacent first guide wheels 151 are spaced along the vertical direction DH. One end of the first transmission member 152 is connected to the driven member 14, and the first transmission member 152 sequentially bypasses the first guide wheels 151 arranged in pairs and the other end is connected to the bracket 12. Accordingly, the second guide wheels 153 have a plurality of, for example Figure 5 In the embodiment, there are three second guide wheels 153 connected to a single second transmission member 154. One end of the second transmission member 154 is connected to the driven member 14, and the second transmission member 154 sequentially bypasses the plurality of second guide wheels 153 and the other end is connected to the bracket 12.

[0130] It should be noted that Figure 5 In the embodiment, the first horizontal direction D1 can be configured as the length direction DL of the container 1, and correspondingly, the second horizontal direction D2 is configured as the width direction DW of the container 1. At this time, the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are spaced apart along the width direction DW of the container 1. It can be understood that the first horizontal direction D1 can be configured as the width direction DW of the container 1, and correspondingly, the second horizontal direction D2 is configured as the length direction DL of the container 1. At this time, the connection point between the first transmission member 152 and the bracket 12 and the connection point between the second transmission member 154 and the bracket 12 are spaced apart along the length direction DL of the container 1.

[0131] See also Figure 3 and Figure 6In order to ensure the moving accuracy of the bracket 12 in the direction consistent with the extending direction of the screw rod 172 and prevent the bracket 12 from being offset in the horizontal direction during the lifting process, the lifting frame 11 also includes a limit assembly 19. The limit assembly 19 is used to be connected to the container 1, and the limit assembly 19 is used to cooperate with the transmission assembly 15 to ensure that the bracket 12 moves in the vertical direction DH. The limit assembly 19 has a limit groove 19a, the extending direction of the limit groove 19a is consistent with the setting direction of the screw rod 172, and the bracket 12 is partially connected to the limit groove 19a. Specifically, the limit assembly 19 includes a column 191, the setting direction of the column 191 is consistent with the setting direction of the screw rod 172, and the columns 191 are arranged in pairs and spaced from each other to form the limit groove 19a. For example, the columns 191 are arranged in the vertical direction DH, and adjacent columns 191 are spaced along the length direction DL of the container 1, and the adjacent columns 191 along the length direction DL of the container 1 are connected by a plurality of fixing members 192.

[0132] It can be understood that when the screw rod 172 is Figure 5 When arranged in the horizontal direction as shown, the aforementioned slide groove 16a and the limiting groove 19a extend in the horizontal direction, and correspondingly, the column 191 is arranged in the horizontal direction.

[0133] It should be noted that the bracket 12 can be constructed to be movably connected to the lifting device 13 between a first position and a second position along the vertical direction DH, and the first position is located below the second position. After the bracket 12 rises to a predetermined position, the position of the bracket 12 needs to be locked, so the lifting frame 11 also includes a support assembly 20. The support assembly 20 includes a support member 21 and an operating member 22. Specifically, the support member 21 has a card interface 21a suitable for the bracket 12, and the support member 21 is pivotally connected to the limit assembly 19 between the third position and the fourth position. The operating member 22 is connected to the support member 21, and the operating member 22 is used to drive the support member 21 to rotate between the third position and the fourth position. Further, the support member 21 located at the third position is separated from the bracket 12, and the support member 21 located at the fourth position is engaged with the bracket 12 located at the second position.

[0134] For details, please refer to Figure 3 , Figure 7 and Figure 8 The bracket 12 has a clamping member 126 and a hanging member 127.
