[0069] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0070] This utility model provides a loading and unloading system.

[0071] Please see Figure 1 The loading and unloading system 100 includes at least one housing 110 and at least one hoisting device 120. The top of the housing 110 has an opening 112 communicating with the outside and the interior of the housing 110 (see...). Figure 5 The hoisting device 120 is positioned on top of the enclosure 110. The enclosure 110 includes a top beam 113 and a top side beam 114. The hoisting device 120 includes a column 121, a hoisting assembly 130, and at least one diagonal brace 122. Specifically, the column 121 is arranged vertically. The hoisting assembly 130 is pivotally connected to the column 121 about a first axis extending vertically. The hoisting assembly 130 is used for hoisting between the interior and exterior of the enclosure 110 via an opening 112. The diagonal brace 122 is arranged at an angle relative to the vertical direction, with one end of the diagonal brace 122 connected to the column 121, and the other end of at least one diagonal brace 122, away from the column 121, connected to either the top beam 113 or the top side beam 114.

[0072] According to the loading and unloading system 100 of this scheme, since the container 110 is equipped with its own hoisting equipment 120, it can improve loading and unloading efficiency, reduce the dependence of the container 110 on external hoisting equipment, and adapt to different working environments.

[0073] Please see Figures 1 to 3 The loading and unloading system 100 also includes a top cover 111, which is detachably connected to the housing 110 to open and close the opening 112 (see...). Figure 5 The top cover 111 is connected to the container body 110, for example, by fasteners or door hinges. When lifting operations are required, the top cover 111 is opened, allowing the cargo opening 112 to be transported to a designated location outside the container body 110. Preferably, the aforementioned container body 110 is constructed as a shipping container (e.g., a 20-foot, 40-foot, etc.), and the lifting equipment 120 is constructed as a cantilever crane. Those skilled in the art know that a shipping container is a large cargo box with standardized dimensions and strength, facilitating mechanical loading, unloading, and transshipment. It is reusable, typically a cuboid structure, and is usually made of steel, aluminum alloy, or fiberglass, with uniform specifications (e.g., 20-foot, 40-foot, etc.). A cantilever crane is a lifting device that uses a fixed or movable column as support. It achieves the lifting of heavy objects by rotating, pitching, or extending / retracting the cantilever beam (arm) around the column. It is suitable for material handling in localized areas such as workshops, warehouses, and docks, and features a compact structure and flexible operation. Combining a container with a cantilever crane can improve the flexibility of the loading and unloading system and adapt to different operational needs.

[0074] It is understood that the aforementioned top beam 113 is arranged along the width direction of the container, and the top side beam 114 is arranged along the length direction of the container. The top beam 113 and the top side beam 114 are generally supplemented with corner brackets to enclose and form the outer frame of the container's top panel assembly.

[0075] A single hoisting device is detachably connected to at least one housing 110.

[0076] For example, the hoisting equipment is installed in a one-to-one correspondence with the housing 110. Please refer to [link / reference]. Figures 1 to 4 The loading and unloading system 100 includes a container 110 and a hoisting device 120. The loading and unloading system 100 can be used independently or in conjunction with other loading and unloading systems 100 (refer to loading and unloading system 200). It can realize the rapid hoisting and transportation of materials inside the container 110 to the outside, and is particularly suitable for use in small warehouses, transportation transfer stations and other scenarios.

[0077] Alternatively, please refer to Figure 5 and Figure 6 The loading and unloading system 200 includes two boxes 110 and two hoisting devices 120. Figure 5 and Figure 6 In the image, one of the hoisting devices 120 is omitted to show its installation position on the housing 110.

[0078] Of course, in embodiments not shown, the loading and unloading system may also include three or more boxes 110 and three or more hoisting devices 120 corresponding to the boxes 110.

[0079] Alternatively, a single hoisting device may correspond to at least two housings 110. See also... Figure 7 and Figure 8 The loading and unloading system 300 includes a hoisting device 220 and two enclosures 110. Please refer back now. Figure 5 and Figure 6 A single hoisting device 120 can also be configured to be disassembled and replaced between two housings 110. That is, a single hoisting device 220 corresponds to two housings 110.

[0080] Of course, in embodiments not shown, the loading and unloading system may also include three or more boxes 110, and a single hoisting device 120 may correspond to three or more boxes 110.

[0081] The following describes the installation and connection between the hoisting equipment and the housing 110.

[0082] Please see Figure 1 The loading and unloading system 100 includes a base 124 disposed on top of the housing 110. A lifting device 120 is detachably connected to the base 124. For example, the lifting device 120 also includes a base 123 disposed at the bottom of the column 121. The base 123 protrudes horizontally from the column 121 and is used for connection to the housing 110. Specifically, the base 123 and the base 124 have corresponding connection holes, and a connection between the base 123 and the base 124 is established by installing fasteners into these connection holes.

[0083] Alternatively, the loading and unloading system 200 includes at least two bases 124, each corresponding to a housing 110 and located on top of the housing 110. Please refer to [link / reference]. Figure 5 and Figure 6 The loading and unloading system 200 includes two bases 124 and two housings 110. Each housing 110 has a corresponding base 124 on its top. When a single lifting device 120 corresponds to at least two housings 110, the lifting device 120 is detachably connected to one of the bases 124. That is, the lifting device 120 can be disassembled and replaced between different bases 124. When multiple lifting devices 120 are configured in a one-to-one correspondence with multiple housings 110, it can be understood that the lifting devices 120 are detachably connected to the corresponding bases 124.

[0084] Alternatively, a single base 124 may be positioned on top of at least two housings 110, with the lifting device 120 detachably connected to the base 124. See now. Figure 7 and Figure 8 The loading and unloading system 300 includes a lifting device 220 and two housings 110, with a single base 224 positioned on top of the two housings 110. The lifting device 220 is detachably connected to the base 224.

[0085] The base is the main load-bearing and positioning component. Depending on the application scenario, it is optional to install lifting equipment. Depending on the load, reinforcements such as support columns or diagonal braces can be added below the base to increase its load-bearing capacity and stability. Lifting equipment is easier to assemble and disassemble than the base; for example, the layout of the lifting equipment can be modified to suit different application scenarios.

[0086] The following describes the connection between the diagonal brace 122, the box body 110, and the column.

[0087] The diagonal brace 122 is inclined relative to the column, with one end connected to the column and the other end, away from the hoisting equipment, connected to the housing 110. For details, please refer to... Figure 2 and Figure 4The hoisting equipment 120 also includes a first pin 142 and a second pin 144. Specifically, the first pin 142 is disposed between the column 121 and the diagonal brace 122. The column 121 and the diagonal brace 122 have corresponding first mounting holes, and the first pin 142 is connected to the first mounting holes of the column 121 and the diagonal brace 122 to establish a connection between the diagonal brace 122 and the column 121. The second pin 144 is disposed between the housing 110 and the diagonal brace 122. The housing 110 and the diagonal brace 122 have corresponding second mounting holes, and the second pin 144 is connected to the second mounting holes of the housing 110 and the diagonal brace 122. It can be understood that during the installation phase of the diagonal brace 122, the diagonal brace 122 can pivot about the axis of either the first pin 142 or the second pin 144. To prevent the first pin 142 and the second pin 144 from slipping off their corresponding mounting holes after installation, both the first pin 142 and the second pin 144 are provided with limiting holes that extend radially through them. These limiting holes are used to install limiting components 145. The limiting component 145 is, for example, constructed as a cotter pin. Furthermore, a first support 141 is provided at the column 121, and a second support 143 is provided at the housing 110. The first support 141 has a first mounting hole suitable for the diagonal brace 122, and the second support 143 has a second mounting hole suitable for the diagonal brace 122. The second support 143 is the connection point between the diagonal brace 122 and the housing 110, and its function is to transfer the tensile force generated by the diagonal brace 122 to the housing 110. The second support 143 is connected to the housing 110, for example, by welding or fasteners, and the diagonal brace 122 is flexibly fixed to the housing 110 by the second pin 144 (or bolts). The pin can withstand the shear force generated between the column, diagonal brace 122 and support when the hoisting equipment is lifting.

[0088] Please see now Figure 1 , Figure 5 and Figure 7 The number of diagonal braces 122 can be set to multiple. Figure 1 In this system, three diagonal braces 122 are distributed on the outer periphery of the column 121. It should be noted that the function of the diagonal braces 122 is to enhance the load-bearing capacity and anti-overturning performance of the hoisting equipment. The diagonal braces 122 are designed based on mechanical principles. Through precise calculation of key parameters such as the diagonal angle, material strength, and connection method, the diagonal braces 122 and the column form a highly efficient and stable mechanical system. During hoisting, they can fully exert their supporting and balancing functions, effectively reducing the risk of structural deformation and overturning. The material of the diagonal braces 122 can be profiles, flat steel, steel cables, or other tensile steel materials. Figure 1 In the middle, one end of the diagonal brace 122 is connected to the column 121. Among them, the other end of one diagonal brace 122 away from the column 121 is connected to the top beam 113, and the other end of two diagonal braces 122 away from the column 121 is connected to the top side beam 114. Figure 5 and Figure 1The situation is similar, so I won't go into details. Figure 7 In this structure, there are four diagonal braces 122 distributed on the outer periphery of the column 221. One end of each diagonal brace 122 is connected to the column 221. Two of the diagonal braces 122, with their ends away from the column 221, are connected to the top beam 113, and two of the diagonal braces 122, with their ends away from the column 221, are connected to the top side beam 114. That is, at least one diagonal brace 122, with its end away from the column, is connected to either the top beam 113 or the top side beam 114.

[0089] The structure of the hoisting equipment is described below.

[0090] Please see Figure 1 and Figure 3 The hoisting equipment 120 also includes a support member 125 and a rotating arm 126. Specifically, the support member 125 is disposed on the column 121 and protrudes radially from the outer circumference of the column 121. The rotating arm 126 is disposed vertically in the direction DH and is pivotally connected to the support member 125 about a first axis. The hoisting assembly 130 is connected to the rotating arm 126 and can pivot with the rotating arm 126. Further, the support members 125 are arranged in pairs, with the two support members 125 spaced vertically. The rotating arm 126 is disposed between the two support members 125, spaced horizontally from the column 121, and connected at both ends to the support members 125. The hoisting assembly 130 includes a crossbeam 131, a hook 132, and a sliding member 133. The crossbeam 131 is disposed horizontally and one end is connected to the rotating arm 126. The sliding member 133 is movably connected to the crossbeam 131 along its extension direction. The hook 132 is connected to the sliding member 133 and can move with it. It is understood that, due to the constraint of the column 121, the lifting assembly 130 can generally pivot 180° about a first axis, which is the axis of the rotating arm 126. To improve the connection strength between the lifting assembly 130 and the rotating arm 126, the lifting device 120 also includes a reinforcing member 127 disposed between the lifting assembly 130 and the rotating arm 126. The reinforcing member 127 is inclined relative to the rotating arm 126, with one end connected to the rotating arm 126 and the other end connected to the crossbeam 131 away from the rotating arm 126. Preferably, both the loading / unloading system 100 and the loading / unloading system 200 include the lifting device 120.

[0091] Please see now Figure 7 and Figure 8Alternatively, the loading and unloading system 300 includes a hoisting device 220. Compared to the hoisting device 120, the support member 125 and the rotating arm 126 are omitted, and the hoisting assembly 130 is mounted on the column 221. Specifically, the column 221 includes a main body 222 and a pivoting part 223. The pivoting part 223 is located on the upper part of the main body 222 and is pivotally connected to the main body 222 about a first axis. The hoisting assembly 230 is located on the pivoting part 223 and can pivot with the pivoting part 223. It can be understood that, in this case, the first axis is the axis of the pivoting part 223. Accordingly, a reinforcing member 227 is disposed between the hoisting assembly 130 and the column 221. The reinforcing member 227 is inclined relative to the column 221, with one end of the reinforcing member 227 connected to the pivoting part 223 and the other end of the reinforcing member 227 away from the pivoting part 223 connected to the crossbeam 131. The hoisting equipment 220 can pivot 360° relative to the column 221 to adapt to different usage needs.

[0092] According to the loading and unloading system of this utility model, the combination of the container and the hoisting equipment enables the rapid and flexible assembly and disassembly of the hoisting equipment to adapt to the needs of different logistics operation scenarios. After reasonable assembly according to different usage requirements, it is possible to use the hoisting equipment to carry out hoisting and transportation operations between multiple containers or between the inside of a container and the outside.
