[0002] Logistics containers are standardized, enclosed containers used for transporting and storing goods. They are typically made of steel or aluminum, boasting a sturdy structure and waterproof and moisture-resistant properties. Currently, there are many types of logistics containers, including those suitable for air transport, those suitable for sea transport, and truckable containers suitable for land transport. Truckable containers typically refer to containers that can be loaded onto trucks or trailers, allowing them to be directly integrated into transport vehicles for easy road transport.

[0003] Currently, reach stackers or large cranes are commonly used to load and unload truckable containers. While these can handle the loading and unloading process, they are generally large. Besides scenarios where a reach stacker or large crane can be installed, there are also some special cases, such as when a large crane or reach stacker is not available, when there are few containers to be removed, and when installing a reach stacker or large crane is expensive. In these special cases, containers cannot be loaded or unloaded.

[0004] In the invention with application number: CN202410532735.2 and publication number: CN118108098A, a container lifting device is disclosed, including an automatic centering clamping unit, a secondary fixing unit and a secondary clamping mechanism.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1 to 2 As shown, in order to solve the above problems, this embodiment discloses a mobile container lifting and loading and unloading device, including a base 10, a lifting clamping assembly 20 and a moving assembly 30.

One end of the rotating connecting block 300 is fixedly connected to the rotating connecting rod 306.

[0037] The mobile container lifting and loading and unloading device described in the present invention requires four devices to be used together. When in use, the mobile container lifting and loading and unloading device can be manually tilted so that the wheels 303 contact the ground, and then the mobile container lifting and loading and unloading device can be pulled to a designated position for use. Compared with traditional cranes or reach stackers, the mobile container lifting and loading and unloading device described in the present invention is smaller in size and can be carried with a vehicle or container. It is also movable. When container loading and unloading needs to be completed, the four mobile container lifting and loading and unloading devices and manual labor can complete the container loading and unloading, solving the current problem of being unable to load and unload containers when a large crane or reach stacker is not in place.

[0038] The utility model arranges a pair of mounting rods 304 on the base 10, arranges a pair of fixed connecting blocks 305 on the pair of mounting rods 304 respectively, arranges a rotatable rotating connecting rod 306 between the pair of fixed connecting blocks 305, and then fixes the rotating connecting block 300 in the moving component 30 to the rotating connecting rod 306, so that the moving component 30 can be flipped.

[0039] like Figure 2 As shown, a fixed bracket 307 is provided above a pair of fixed connecting blocks 305, and the bottom of the fixed bracket 307 is fixedly connected to the pair of fixed connecting blocks 305 respectively. The upper end of the mounting bracket 301 can contact the upper end of the fixing bracket 307, and the upper end of the mounting bracket 301 and the upper end of the fixing bracket 307 are respectively provided with a matching magnetic suction part 308.

[0040] The magnetic attraction member 308 is a pair of magnets. The upper end of the mounting bracket 301 and the upper end of the fixed bracket 307 are both provided with mounting grooves 309 that cooperate with the magnets. The pair of magnets are fixed in the mounting grooves 309 on the upper end of the mounting bracket 301 and the upper end of the fixed bracket 307 respectively.

[0041] When in use, the initial position of the moving assembly 30 is the position where the upper end of the mounting bracket 301 and the upper end of the fixed bracket 307 are attracted by magnets;

[0042] During the container loading and unloading process, the moving assembly 30 needs to be turned over until the pair of wheels 303 are in contact with the ground, thereby improving the stability during the container loading and unloading process.

[0043] like Figures 3 and 4 As shown, in order to facilitate the loading and unloading of containers, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the lifting and clamping assembly 20 includes a lifting structure 21, a transmission structure 22, a clamping structure 23 and a driving structure 24. The lifting structure 21 includes a main beam 200 and a sliding sleeve 201. The main beam 200 is vertically arranged on the base 10 and is perpendicular to the base 10. The main beam 200 is located on one side of a pair of mounting rods 304 and is arranged in conjunction with the pair of mounting rods 304. The sliding sleeve 201 is arranged on the main beam 200 and is slidably connected to the main beam 200. The driving mechanism 24 is configured to be a lifting mechanism 21, a transmission structure 22, a clamping structure 23 and a driving mechanism 24. The lifting structure 21 includes a main beam 200 and a sliding sleeve 201. The main beam 200 is vertically arranged on the base 10 and is perpendicular to the base 10. The main beam 200 is located on one side of a pair of mounting rods 304 and is arranged in conjunction with the pair of mounting rods 304. The sliding sleeve 201 is arranged on the main beam 200 and is slidably connected to the main beam 200. The dynamic structure 24 is arranged on one side of the main beam 200, and the bottom is located between a pair of mounting rods 304. The bottom of the driving structure 24 is fixedly connected to the base 10. The transmission structure 22 is arranged on one side of the sliding sleeve 201, and one end is fixedly connected to the sliding sleeve 201. The transmission structure 22 and the driving structure 24 are arranged in coordination. The driving structure 24 can drive the sliding sleeve 201 to slide on the main beam 200 through the transmission structure 22. The clamping structure 23 is arranged on the other side of the sliding sleeve 201, and one end is fixedly connected to the sliding sleeve 201. The clamping structure 23 and the transmission structure 22 are arranged in coordination for clamping with the corner fittings at the bottom of the container.

[0044] The size of the mobile container lifting and loading and unloading device described in the present invention is mainly determined by the height of the main beam 200. Generally speaking, the height of the main beam 200 ranges from 1.8 to 2 meters and can be set according to actual needs.

[0045] The clamping structure 23 includes a supporting portion 202 and a clamping portion 203 . The supporting portion 202 is disposed on the upper end of the sliding sleeve 201 , and the clamping portion 203 is disposed on the lower end of the sliding sleeve 201 .

[0046] The support portion 202 includes a support plate 204 and a pair of first connecting plates 205. The pair of first connecting plates 205 are arranged on one side of the support plate 204. One end of the pair of first connecting plates 205 is fixedly connected to one side of the support plate 204, and the other end is fixedly connected to both sides of the upper end of the sliding sleeve 201.

[0047] The clamping portion 203 includes a clamping plate 206, a clamping piece 207 and a pair of second connecting plates 208. The pair of second connecting plates 208 are arranged on one side of the clamping plate 206. One end of the pair of second connecting plates 208 is fixedly connected to the clamping plate 206, and the other end is fixedly connected to the two sides of the lower end of the sliding sleeve 201 respectively. The clamping piece 207 is arranged on the clamping plate 206 and is used to clamp with the corner piece at the bottom of the container.

[0048] During use, the sliding sleeve 201 can be manually moved and the mounting bracket 301 can be stepped on so that the clamping piece 207 on the clamping plate 206 is clamped into the corner piece at the bottom of the container, and the clamping plate 206 and the support plate 204 are in contact with the surface of the container, thereby facilitating the connection of the container with the mobile container lifting and unloading device described in the utility model.

[0049] like Figures 5 and 6 As shown, in order to further facilitate the connection between the mobile container lifting and unloading device described in the present invention and the container, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the clamping member 207 includes a fixed sleeve 209, a clamping block 210, a rotating shaft 211 and a rotating handle 212. One end of the fixed sleeve 209 passes through the clamping plate 206 and is fixedly connected to the clamping plate 206. The rotating shaft 211 is arranged in the fixed sleeve 209 and is rotatably connected to the fixed sleeve 209. The clamping block 210 is fixedly arranged on one side of the rotating shaft 211, and the rotating handle 212 is fixedly arranged on the other side of the rotating shaft 211. A limiting slide bar 213 is provided on the rotating handle 212, and a limiting slide groove 214 is provided on the fixed sleeve 209 to cooperate with the limiting slide bar 213. One end of the limiting slide bar 213 is located in the limiting slide groove 214 and is slidably connected to the limiting slide groove 214.

[0050] During use, when the clamping block 210 is inserted into the corner fitting at the bottom of the container, the rotating shaft 211 is driven by rotating the handle 212, thereby driving the clamping block 210 to rotate, so that the clamping block 210 is clamped in the corner fitting at the bottom of the container, thereby facilitating the connection between the mobile container lifting and unloading device described in the utility model and the container. When disassembling, it is only necessary to rotate the rotating handle 212 in the opposite direction.

[0051] The limiting sliding groove 214 is an arc-shaped groove, which is used to limit the rotation angle of the limiting sliding rod 213.

[0052] Preferably, the rotatable angle of the limiting slide bar 213 is 90°, so as to facilitate the clamping block 210 to be clamped in the corner piece of the bottom of the container.

[0053] In one embodiment, the rotatable angle of the limiting slide 213 is 90° counterclockwise, and the limiting slide groove 214 is arranged in conjunction with the limiting slide 213 to limit the rotatable angle of the limiting slide 213 to 90° counterclockwise, so that the clamping block 210 can be rotated 90° counterclockwise and thus clamped in the corner piece at the bottom of the container.

[0054] like Figure 4 、 Figure 7As shown, at the same time, the mobile container lifting and loading and unloading device described in the utility model requires four to be used in conjunction when in use. In order to improve the stability of the container during loading and unloading, it is preferred that a pair of curved plates 215 are respectively provided on one side of a pair of first connecting plates 205, and one end of a pair of curved plates 215 is respectively fixedly connected to a pair of first connecting plates 205, and a pair of curved plates 215 are each provided with a through hole 216.

[0055] Preferably, four lashing ropes are further included. When in use, two adjacent mobile container lifting and loading and unloading devices can be fixed by the lashing ropes, which can pass through the through holes 216 and be fixed on the curved plate 215 and contact the container surface.

[0056] like Figures 3 and 4 As shown, in order to facilitate the movement of the sliding sleeve 201 and thus complete the disassembly of the container, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the transmission structure 22 includes a first pin shaft 217, a second pin shaft 218 and a pair of transmission mounting brackets 219. One end of the pair of transmission mounting brackets 219 is fixedly connected to both sides of the sliding sleeve 201, and one end of the pair of transmission mounting brackets 219 is located between the support portion 202 and the clamping portion 203. The pair of transmission mounting brackets 219 are each provided with a pair of first pin holes 220, and the pair of first pin holes 220 are respectively located at At the upper and lower ends of a pair of transmission mounting frames 219, one end of the first pin shaft 217 can be respectively inserted into a pair of first pin holes 220, a second pin hole 221 is provided in the middle of the main beam 200, and the second pin hole 221 passes through the main beam 200, and one end of the second pin shaft 218 can be inserted into the second pin hole 221. One side of a pair of transmission mounting frames 219 is respectively provided with a first placement portion 222 and a second placement portion 223 for placing the first pin shaft 217 and the second pin shaft 218, one end of the first pin shaft 217 can be inserted into the first placement portion 222, and one end of the second pin shaft 218 can be inserted into the second placement portion 223.

[0057] Among them, the driving structure 24 includes a hydraulic cylinder 224 and a fixing plate 225. The fixing plate 225 is arranged at the bottom of the hydraulic cylinder 224 and is fixedly connected to the bottom of the hydraulic cylinder 224. The fixing plate 225 is fixedly connected to the base 10 by bolts. The output end of the hydraulic cylinder 224 is provided with an arc-shaped clamping block 226. The arc-shaped clamping block 226 is fixedly connected to the output end of the hydraulic cylinder 224. The arc-shaped clamping block 226 can contact the first pin shaft 217 under the drive of the hydraulic cylinder 224.

[0058] like Figure 7 As shown, the mobile container lifting and loading and unloading device described in the present invention is divided into three processes during disassembly, as follows:

[0059] 1. First, insert the first pin 217 into the first pin hole 220 located at the upper end of the pair of transmission mounting frames 219. Drive the arc-shaped clamping block 226 to contact the first pin 217 through the output end of the hydraulic cylinder 224. Then continue to drive the first pin 217 to drive the sliding sleeve 201 upward until the bottom of the sliding sleeve 201 is located above the second pin hole 221. Then, insert the second pin 218 into the second pin hole 221. Then, retract the output end of the hydraulic cylinder 224 to the unextended state, so that the bottom of the sliding sleeve 201 contacts the second pin 218. At this time, the clamping block 210 can be manually clamped into the corner fitting at the bottom of the container, and then the binding rope is secured to complete the connection process between the mobile container lifting and unloading device and the container.

[0060] 2. Then insert the first pin shaft 217 into the first pin hole 220 located at the lower end of the pair of transmission mounting frames 219, and then drive the arc clamping block 226 to contact the first pin shaft 217 through the output end of the hydraulic cylinder 224. Then continue to drive the first pin shaft 217 to drive the sliding sleeve 201 upward, thereby lifting the container, and then the freight vehicle can be driven out.

[0061] 3. After the freight vehicle leaves, the output end of the hydraulic cylinder 224 is retracted to the unextended state so that the bottom of the sliding sleeve 201 contacts the second pin shaft 218 again, and then the first pin shaft 217 is inserted into the first pin hole 220 located at the upper end of the pair of transmission mounting frames 219. The output end of the hydraulic cylinder 224 drives the arc clamping block 226 to contact the first pin shaft 217, and then the second pin shaft 218 is pulled out and inserted into the second placement portion 223. Then, the output end of the hydraulic cylinder 224 is further retracted to make the sliding sleeve 201 continue to move downward until the bottom of the container contacts the ground, and the container can be disassembled.

[0062] The installation of the mobile container lifting and loading and unloading device described in this utility model is divided into two steps, as follows:

[0063] 1. First, insert the first pin shaft 217 into the first pin hole 220 located at the upper end of the pair of transmission mounting brackets 219. Manually clamp the clamping block 210 into the corner fitting at the bottom of the container. Then, secure the binding rope. Then, the output end of the hydraulic cylinder 224 drives the arc-shaped clamping block 226 to contact the first pin shaft 217, completing the connection process between the container and the mobile container lifting and loading and unloading device.

[0064] 2. Then, the hydraulic cylinder 224 drives the first pin 217 to drive the sleeve 201 to move upward until the bottom of the sleeve 201 is located above the second pin hole 221. Then, the second pin 218 is inserted into the second pin hole 221. Then, the output end of the hydraulic cylinder 224 is retracted to the unextended state, so that the bottom of the sleeve 201 contacts the second pin 218. Then, the first pin 217 is inserted into the first pin hole 220 located at the lower end of the pair of transmission mounting brackets 219. The output end of the hydraulic cylinder 224 drives the arc clamping block 226 to contact the first pin 217. Then, the first pin 217 is driven to drive the sleeve 201 to move upward, and the sleeve 201 is moved upward. The container is lifted, and then the freight vehicle is driven in. The hydraulic cylinder 224 is then slowly retracted to the unextended state. The container is manually installed on the freight vehicle. The first pin shaft 217 is then inserted into the first pin hole 220 at the upper end of a pair of transmission mounting frames 219. The arc clamping block 226 is driven to contact the first pin shaft 217 through the output end of the hydraulic cylinder 224. The second pin shaft 218 is then pulled out and inserted into the second placement portion 223, and the binding rope is released.
