Description

Technical Field

[0001] This utility model relates to the field of container transshipment technology, specifically to a heavy-duty transshipment device. Background Technology

[0002] Currently, in container ports, straddle carriers are commonly used to lift containers and facilitate container transfer by moving the carriers. Existing technology typically involves lifting containers from the top or bottom. However, with the increasing capacity of containers, their height and weight are also increasing, placing greater demands on the height of straddle carriers and the structural strength of the containers. Utility Model Content

[0003] In view of this, the present invention provides a heavy-duty transfer device to solve the problem that with the development of large-capacity containers, the height and weight of containers are increasing, and the requirements for the height of straddle carriers and the structural strength of containers are also increasing.

[0004] This utility model provides a heavy-duty transfer device, comprising: a lifting and traveling beam extending along a first direction, wherein at least one set of the lifting and traveling beams is provided, each set including two lifting and traveling beams spaced apart from each other along a second direction, and multiple sets of the lifting and traveling beams being arranged side by side along the first direction; a locking mechanism disposed between the two opposing sides of the two lifting and traveling beams in each set and the bottom of the container, for detachably connecting the lifting and traveling beams to the container; and a connecting mechanism connecting at least one set of two lifting and traveling beams.

[0005] Beneficial effects: When containers need to be transferred, the container is connected to the lifting beam by a locking mechanism. The lifting beam then lifts the container to a certain height, and the container can be transferred to the predetermined position by moving the lifting beam. That is, the container is raised by lifting it from the bottom before it is transferred. The top height of the heavy-duty transfer device is unlimited, and the structural strength requirements of the container are low. Even containers with large height and weight can be transferred.

The locking mechanism is disposed on the beam body, and the connecting mechanism connects the beam bodies of the two lifting and traveling crossbeams.

[0015] In one alternative embodiment, the walking mechanism includes a frame and a wheel structure, the wheel structure being connected to the lower surface of the frame, and the lower end of the lifting mechanism being connected to the upper surface of the frame.

[0016] Beneficial effects: The wheel structure enables the container to move and turn, thus achieving flexible movement.

[0017] In one alternative embodiment, the frame has a recess extending downward between adjacent wheel structures, and the lifting mechanism is disposed in the recess; or,

[0018] The frame is flush with the upper end of the wheel structure.

[0019] Beneficial effects: By setting a recess to accommodate at least part of the lifting mechanism in the height direction, the beam can be made to have a lower height after the lifting mechanism is retracted, reducing the space occupied. In addition, the center of gravity of the entire transfer device can be lowered, improving the stability of the transfer device.

[0020] In one optional embodiment, the lifting mechanism includes a bottom connecting seat, a top connecting seat, a hydraulic cylinder, a scissor lift, and a connecting rod. The bottom end of the scissor lift is connected to the vehicle frame via the bottom connecting seat, and the top end of the scissor lift is connected to the beam via the top connecting seat. The scissor lift is hinged to both the bottom and top connecting seats. The hydraulic cylinder is mounted on the vehicle frame and is drivenly connected to the scissor lift. The connecting rod is hinged between the scissor lifts.

[0021] In one optional embodiment, the lifting mechanism includes a bottom connecting seat, a top connecting seat, a hydraulic cylinder, a scissor lift rod, and a connecting rod. The bottom connecting seats are hinged to both bottom ends of the scissor lift rod, and both bottom connecting seats are disposed on the vehicle frame. At least one bottom connecting seat is slidably connected to the vehicle frame. The top end of the scissor lift rod is connected to the beam via the top connecting seat. The scissor lift rod is hinged to the top connecting seat. The hydraulic cylinder is disposed on the vehicle frame and is throttle-connected to the slidably disposed bottom connecting seat. The connecting rod is hinged between the scissor lift rods.

[0022] In one optional embodiment, the wheel structure is provided at intervals along the length of the beam; and / or,

[0025] Beneficial effects: By utilizing the movable combination of the telescopic and fixed structures, the connection and separation of the lifting and walking beam and the container can be realized. The structure is simple and easy to use.

[0026] In one optional embodiment, the retractable structure includes a drive member and a connector, the drive member being pulsatorically connected to the connector, the fixing structure having a fixing hole, and the drive member being adapted to drive the connector to pass into or move out of the fixing hole.

[0029] Beneficial effects: After the connector is inserted into the fixed structure through the fixing hole, the locking pin is driven to rotate at a certain angle by the driving component, so that the locking tongue can overlap with the fixed structure, thereby restricting the locking pin within the fixed structure, ensuring the reliability of the cooperation between the connector and the fixed structure, and improving the safety during container transfer.

[0030] In one alternative embodiment, a plurality of locking mechanisms are provided at intervals along the length of the lifting and traveling beam.

[0034] The connecting beam is a telescopic structure.

[0035] Beneficial effects: It allows the hinged position to move on the connecting beam, thereby increasing the degree of folding of the connecting beam and the two beams, and further reducing the space occupation;

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0064] The following is combined Figures 1 to 21 The following describes embodiments of the present invention.

[0065] According to an embodiment of the present invention, a heavy-duty transfer device is provided, comprising: a lifting and traveling beam 1 extending along a first direction, wherein at least one set of lifting and traveling beams 1 is provided, each set including two lifting and traveling beams 1 spaced apart from each other along a second direction, and multiple sets of lifting and traveling beams 1 arranged side by side along the first direction; a locking mechanism 2 disposed between the two opposite sides of the two lifting and traveling beams 1 in each set and the bottom of the container 100, for detachably connecting the lifting and traveling beams 1 to the container 100; and a connecting mechanism 3 connecting at least one set of two lifting and traveling beams 1.

[0066] When the heavy-duty transfer device of this embodiment needs to transfer the container 100, the container 100 is connected to the lifting and traveling beam 1 by the locking mechanism 2, and then the container 100 is lifted to a certain height by the lifting and traveling beam 1. Then, the container 100 can be transferred to the predetermined position by the movement of the lifting and traveling beam 1. That is, the container 100 is raised by lifting the bottom of the container 100 before it is transferred. The top height of the heavy-duty transfer device is unlimited, and the structural strength requirements of the container 100 are low. Even for containers 100 that are large in height and weight, the transfer can be achieved. The overall structure of the transfer device is simple and the cost is low.

[0067] Understandably, please refer to Figure 19 The first direction is the length direction of the lifting and traveling crossbeam 1. The second direction is set perpendicular to the first direction and is also set perpendicular to the vertical direction (which can also be understood as the height direction).

[0068] It is worth noting that in related technologies, the top connecting frame of a straddle carrier spans across the container 100, and the container 100 is transferred by being lifted from the top. One lifting method involves inserting a spreader mounted on the top connecting frame of the straddle carrier into a mating hole on the top of the container 100, and then lifting the container 100 using a top lifting structure. Another method involves extending the spreader on the top connecting frame of the straddle carrier vertically to the bottom of the container 100, connecting the spreader to the bottom of the container 100, and then lifting the container 100 using a top lifting structure. Afterwards, the straddle carrier moves using transfer wheels located at the bottom of the crossbeams and vertical beams on both sides of the frame to transfer the container 100.

[0069] However, in related technologies, the weight of container 100 is mostly between 20 tons and 80 tons, and the height is around 3 meters. Moreover, with the development of energy storage technology, the energy demand for energy storage container 100 is increasing, which will make the weight and height of container 100 also increase. When using straddle carriers in related technologies to transfer container 100, on the one hand, the structural strength requirements for container 100 are higher, especially for the connection between the spreader and the top of container 100, which increases the structural strength requirements for the top and even the entire container 100. On the other hand, the height of the container 100 that straddle carriers can transfer is limited by the top connecting frame. If the height of the container 100 to be transferred increases, the straddle carrier will also need to be taller. Furthermore, since the container 100 needs to be transferred to the target vehicle, the straddle carrier needs to cross the target vehicle's plane, which will further increase the height of the straddle carrier, resulting in a larger overall size and higher cost. Moreover, such large straddle carriers need to be disassembled and shipped, and then reassembled on-site, which will make the transportation and assembly processes more time-consuming and labor-intensive. In addition, both of the above-mentioned lifting methods for transferring container 100 pose a risk of container swaying, affecting the safety of the transfer process.

[0070] The heavy-duty transfer device provided in this embodiment eliminates the portal frame and top lifting, using a bottom-lifting method to raise the container 100. There is no height limit for the container 100, and the bottom of the container 100 itself has relatively strong structural strength, making it easy to further reinforce. The transfer device in this embodiment connects more conveniently with the bottom of the container 100. Furthermore, compared to the lifting method, the bottom-lifting method results in greater stability of the container 100 during transfer, leading to higher safety performance. In summary, the heavy-duty transfer device provided in this embodiment is smaller, lower in cost, easier to transport and assemble, and offers greater flexibility and safety.

[0071] In the first embodiment of the lifting and traveling beam 1, such as Figure 1 and Figure 18 As shown, a set of lifting and traveling beams 1 is provided, and the connecting mechanism 3 connects the two lifting and traveling beams 1 located at the two ends on the same side. This arrangement facilitates the connection of the two lifting and traveling beams 1 via the connecting mechanism 3, while ensuring that the projections of the connecting mechanism 3 and the container 100 on the horizontal plane do not overlap. In other words, the connecting mechanism 3 does not need to span the container 100, allowing it to maintain a low height, lowering the overall center of gravity of the transfer device, and reducing its space occupation.

[0072] Furthermore, in the first embodiment of the lifting and traveling beam 1, such as Figure 18 As shown, the heavy-duty transfer device also includes an openable and closable tailgate structure 5. In a set of two lifting and traveling beams 1, the two ends on the first side are connected by a connecting mechanism 3, and the two ends on the second side are connected by the tailgate structure 5. By providing the tailgate structure 5, it can be closed during operation of the transfer device, further strengthening the connection between the two lifting and traveling beams 1 and improving the stability and structural strength of the transfer device.

[0073] It is understandable that, such as Figure 18 As shown, when a set of lifting and traveling beams 1 is provided, the two ends of the lifting and traveling beams 1 in the set are connected by the connecting mechanism 3 on the left side, and the two ends of the lifting and traveling beams 1 on the right side are connected by the tailgate structure 5.

[0074] In the second embodiment of the lifting and traveling beam 1, such as Figure 19 and Figure 20 As shown, multiple sets of lifting and traveling beams 1 are arranged along the first direction. One set of lifting and traveling beams 1 located at the edge of the first direction is connected at both ends of the edge by a connecting mechanism 3. By setting multiple sets of lifting and traveling beams 1, the transfer of long heavy containers 100 can be realized, and modular transfer can be realized when the transfer device needs to be transported, which is simpler and more convenient.

[0075] Furthermore, in the second embodiment of the lifting and traveling beam 1, such as Figure 20 As shown, the heavy-duty transfer device also includes a tailgate structure 5 that can be opened and closed. A set of lifting and traveling beams 1 located on the first side edge in the first direction are connected at both ends of the edge by a connecting mechanism 3. A set of lifting and traveling beams 1 located on the second side edge in the first direction are connected at both ends of the edge by the tailgate structure 5.

[0076] It is understandable that, such as Figure 20 As shown, when multiple sets of lifting and traveling beams 1 are provided, in the two lifting and traveling beams 1 in the leftmost set, the two ends on the left are connected by the connecting mechanism 3, and in the two lifting and traveling beams 1 in the rightmost set, the two ends on the right are connected by the tailgate structure 5.

[0077] Furthermore, in the second embodiment of the lifting and traveling beam 1, such as Figure 19 As shown, adjacent sets of lifting and traveling beams 1 are set independently, meaning that adjacent sets of lifting and traveling beams 1 are not connected. Or, as... Figure 20 As shown, two adjacent sets of lifting and traveling beams 1 are connected. Specifically, in two adjacent sets of lifting and traveling beams 1, the ends of two parallel lifting and traveling beams 1 that are close to each other are connected by connectors 6. It can be understood that when the transfer device needs to be transported, the connectors 6 can be removed so that each lifting and traveling beam 1 can be independent, thereby realizing the modular combination and transportation of heavy-duty transfer devices.

[0078] It is worth noting that the tailgate structure 5 can be detachably connected to the lifting and traveling beam 1. Specifically, after the lifting and traveling beam 1 is connected to the container 100 through the locking mechanism 2, the tailgate structure 5 can be connected to the corresponding two lifting and traveling beams 1. Furthermore, the tailgate structure 5 can be a plate-like structure.

[0079] It should be noted that, as an alternative implementation method, such as Figure 21 As shown, the connecting mechanism 3 can also be a door frame structure with a certain height in the vertical direction. The two bottom ends of the door frame structure are respectively connected to two lifting and traveling crossbeams 1 in a group. At this time, the connecting mechanism 3 can be set across the container 100.

[0080] Specifically, in one embodiment, such as Figure 3 and Figure 4As shown, the lifting and traveling crossbeam 1 includes a beam body 11, a lifting mechanism 12, and a traveling mechanism 13. The upper end of the lifting mechanism 12 is connected to the beam body 11, and the lower end of the lifting mechanism 12 is connected to the traveling mechanism 13. A locking mechanism 2 is disposed on the beam body 11, and a connecting mechanism 3 connects the beam bodies 11 of the two lifting and traveling crossbeams 1. By disposing of the locking mechanism 2 on the beam body 11 and connecting the two beam bodies 11 through the connecting mechanism 3, after the container 100 and the beam body 11 are connected by the locking mechanism 2, the two beam bodies 11 can move synchronously when the lifting mechanism 12 and the traveling mechanism 13 are running, thereby improving the stability of lifting and traveling the container 100.

[0081] In one embodiment, such as Figure 3 and Figure 4 As shown, the traveling mechanism 13 includes a frame 131 and a wheel structure 132. The wheel structure 132 is connected to the lower surface of the frame 131, and the lower end of the lifting mechanism 12 is connected to the upper surface of the frame 131. The wheel structure 132 enables the container 100 to move and turn, thus achieving flexible movement.

[0082] Specifically, in one embodiment, the wheel structure 132 is an omnidirectional drive wheel. Several wheel structures 132 are spaced apart.

[0083] Specifically, in one embodiment, such as Figure 3 As shown, the lifting mechanism 12 is a scissor-type hydraulic cylinder lifting mechanism, specifically including a bottom connecting seat 121, a top connecting seat 122, a hydraulic cylinder 123, a scissor-type lifting rod 124, and a connecting rod 125. The bottom end of the scissor-type lifting rod 124 is connected to the frame 131 through the bottom connecting seat 121, and the top end of the scissor-type lifting rod 124 is connected to the beam 11 through the top connecting seat 122. The scissor-type lifting rod 124 is hinged to both the bottom connecting seat 121 and the top connecting seat 122. The hydraulic cylinder 123 is mounted on the frame 131 and is connected to the scissor-type lifting rod 124 in a transmission manner. The connecting rod 125 is hinged between the scissor-type lifting rods 124. Driven by the hydraulic cylinder 123, the scissor-type lifting rod 124 can be rotated, thereby raising or retracting the scissor-type lifting rod 124.

[0084] As an alternative implementation, the lifting mechanism 12 includes a bottom connecting seat 121, a top connecting seat 122, a hydraulic cylinder 123, a scissor lift 124, and a connecting rod 125. Both bottom ends of the scissor lift 124 are hinged to the bottom connecting seats 121, and both bottom connecting seats 121 are mounted on the frame 131. At least one bottom connecting seat 121 is slidably connected to the frame 131. The top end of the scissor lift 124 is connected to the beam 11 via the top connecting seat 122, and the scissor lift 124 is hinged to the top connecting seat 122. The hydraulic cylinder 123 is mounted on the frame 131 and is drivenly connected to the slidably mounted bottom connecting seats 121. The connecting rod 125 is hinged between the scissor lift 124. Driven by the hydraulic cylinder 123, the bottom connecting seats 121 can move, thereby raising or retracting the scissor lift 124.

[0085] In one embodiment, such as Figure 3 As shown, the frame 131 has a recess 1311 that extends downward between adjacent wheel structures 132, and a lifting mechanism 12 is disposed in the recess 1311. By providing the recess 1311 to accommodate at least part of the lifting mechanism 12 in the height direction, the beam 11 can be made to have a lower height after the lifting mechanism 12 is retracted, reducing the space occupied. Furthermore, the center of gravity of the entire transfer device can be lowered, improving the stability of the transfer device.

[0086] Of course, in other alternative implementations, such as Figure 4 As shown, the frame 131 can be flush with the upper end of the wheel structure 132.

[0087] In one embodiment, such as Figure 17 As shown, several wheel structures 132 are spaced apart along the length of the beam 11. It is worth noting that each wheel structure 132 can rotate independently, for example, by providing a separate drive component for each wheel structure 132; or, by providing a drive component for only one or several wheel structures 132, with the remaining wheel structures 132 rotating through a transmission component, for example, it can be configured similarly to a heavy-duty tank in the related art.

[0088] In one embodiment, such as Figure 17 As shown, several lifting mechanisms 12 are arranged at intervals along the length of the beam 11.

[0089] In one embodiment, such as Figure 5 and Figure 6As shown, the locking mechanism 2 includes a telescopic structure 21 and a fixed structure 22. The telescopic structure 21 is mounted on one of the lifting and traveling beam 1 and the container 100, and the fixed structure 22 is mounted on the other of the lifting and traveling beam 1 and the container 100. The telescopic structure 21 and the fixed structure 22 are movably coupled together. The movable coupling of the telescopic structure 21 and the fixed structure 22 enables the connection and separation of the lifting and traveling beam 1 and the container 100, resulting in a simple structure and convenient use.

[0090] It is worth noting that in this embodiment, the telescopic structure 21 is installed on the lifting and traveling crossbeam 1, and correspondingly, the fixed structure 22 is installed on the container 100. This arrangement avoids significant impact on the structure of the container 100 itself and meets the existing specifications of the container 100.

[0091] Specifically, in one embodiment, such as Figure 5 and Figure 6 As shown, the retractable structure 21 includes a driving member 211 and a plug-in member 212. The driving member 211 and the plug-in member 212 are connected in a transmission manner. The fixed structure 22 has a fixing hole 221. The driving member 211 is adapted to drive the plug-in member 212 to pass into or move out of the fixing hole 221.

[0092] It is worth noting that, please refer to Figure 5 A mounting base 14 is provided on the beam 11, and the mounting base 14 forms a receiving groove 141. At least a portion of the driving member 211 is located in the receiving groove 141, thereby reducing the occupation of external space.

[0093] Furthermore, in one embodiment, such as Figure 5 As shown, the connector 212 includes a locking pin 2121 and a locking tongue 2122. One end of the locking pin 2121 is connected to the driving member 211, and the locking tongue 2122 is connected to the other end of the locking pin 2121. At least a portion of the locking tongue 2122 extends out of the outer periphery of the locking pin 2121. The driving member 211 is adapted to drive the locking pin 2121 to rotate, so that the locking tongue 2122 has a movable position that can pass through the fixing hole 221 and a fixed position that is confined inside the fixing structure 22. With this configuration, after the connector 212 is inserted into the fixing structure 22 through the fixing hole 221, the driving member 211 drives the locking pin 2121 to rotate by a certain angle, so that the locking tongue 2122 can overlap with the fixing structure 22, thereby confining the locking pin 2121 within the fixing structure 22, ensuring the reliability of the cooperation between the connector 212 and the fixing structure 22, and improving the safety of the container 100 during transportation.

[0094] It is worth noting that, in this embodiment, as Figure 1 and Figure 2As shown, the container 100 includes a body 101 and a base 102, with the body 101 positioned above the base 102. The fixing structure 22 is a square, hollow corner piece, with fixing holes 221 on two adjacent sides. The fixing holes 221 are oblong, and these corner pieces are located at at least four corners of the base 102. The two sides with fixing holes 221 are located on adjacent sides of the base 102, allowing different sides of the base 102 to connect with the lifting and traveling beam 1, making the transfer of the container 100 more flexible. Of course, the fixing structure 22 can also be installed at other locations on the base 102.

[0095] It should be noted that the driving component 211 can be a single component, capable of both linear and rotary drive; the driving component 211 can also include two components, namely a linear drive component and a rotary drive component, which are connected by transmission.

[0096] As an alternative implementation, a telescopic structure 21 is disposed on the container 100, and a fixed structure 22 is disposed on the lifting and traveling beam 1. The telescopic structure 21 includes a movable locking pin, and the upper side of the fixed structure 22 forms a supporting surface. The movable locking pin is adapted to abut against the supporting surface. When the container 100 needs to be transferred, the movable locking pin extends from the container 100. At this time, the movable locking pin and the supporting surface are arranged opposite each other in the vertical direction. Then, the lifting and traveling beam 1 is raised, and the supporting surface of the fixed structure 22 can cooperate with the movable locking pin to abut against it, thereby lifting the container 100. Specifically, a downward groove can be formed on the upper side of the fixed structure 22, and the groove wall forms the aforementioned supporting surface.

[0097] In one embodiment, such as Figures 7 to 12 As shown, the connecting mechanism 3 includes a connecting beam 31, with both ends of the connecting beam 31 hinged to two beam bodies 11 respectively. By hingedly connecting the connecting beam 31 and the beam bodies 11, the connecting beam 31 and the beam bodies 11 can be folded when the transfer device is idle or during transportation, reducing the space occupied.

[0098] It is worth noting that the transfer device has a working state and a storage state. In the working state, the two beams 11 are arranged in parallel, and the connecting beam 31 is arranged perpendicular to both beams 11. The positions of the beams 11 and the connecting beam 31 are locked and fixed by locking pins, so that the transfer device is kept in the working state. In the storage state, the locking pins are released from fixing the beams 11 and the connecting beam 31. The connecting beam 31 and the beams 11 are rotated as close as possible to achieve folding. At this time, the positions of the beams 11 and the connecting beam 31 can be locked and fixed by locking pins again, so that the transfer device is kept in the storage state, thereby ensuring the stability of the transfer device during the transportation process.

[0099] Specifically, in one implementation, such as Figure 7As shown, the connecting beam 31 is a strip beam, and both beams 11 are also strip beams. Figure 8 As shown, in the stowed state, the connecting beam 31 is inclined, and the two beams 11 remain parallel and close to each other.

[0100] Specifically, in another implementation, such as Figure 9 and Figure 10 As shown, the connecting beam 31 is a strip beam, one of the two beam bodies 11 is an L-shaped beam, and the other of the two beam bodies 11 is a strip beam. Figure 9 As shown, in the working state, the connecting beam 31 is collinear with the first side of the L-shaped beam and perpendicular to the second side of the L-shaped beam; the connecting beam 31 is perpendicular to the beam body 11, which is a strip beam; as Figure 10 As shown, in the stowed state, the connecting beam 31 is perpendicular to the first side of the L-shaped beam and parallel to the second side of the L-shaped beam, and the connecting beam 31 is collinear with the beam body 11, which is a strip beam.

[0101] In one embodiment, at least one of the two hinged positions of the two beams 11 and the connecting beam 31 is movably disposed on the connecting beam 31. This allows the hinged positions to move on the connecting beam 31, thereby increasing the degree of folding of the connecting beam 31 and the two beams 11 and further reducing space requirements.

[0102] Specifically, in one implementation, such as Figure 11 and Figure 12 As shown, the connecting beam 31 has an approximate triangular structure with three vertices. The longest side is formed between two adjacent vertices, and the shortest side is formed between the other two adjacent vertices. Figure 11 As shown, in the working state, the two beams 11 are hinged at the two vertices corresponding to the longest side; as Figure 12 As shown, in the stowed state, the two beams 11 are hinged to the two vertices corresponding to the shortest side (that is, the hinge position of one beam 11 is transferred to the other vertex).

[0103] In one embodiment, such as Figure 13 As shown, the connecting beam 31 is a telescopic structure. This telescopic design allows the connecting beam 31 to be adapted to containers 100 of different sizes, improving the applicability and flexibility of the transfer device.

[0104] Specifically, an expansion mechanism 32 can be set between the two beam segments, or the two beam segments can be nested to achieve expansion and contraction.

[0105] It is worth noting that in other alternative embodiments, the connecting mechanism 3 may also include lifting and traveling components in addition to the connecting beam 31, in order to cooperate with the lifting and traveling crossbeam 1 to achieve lifting and traveling.

[0106] In one embodiment, such as Figure 16 As shown, two lifting and traveling crossbeams 1 can be provided on both sides of the connecting beam 31, thereby enabling the synchronous transfer of multiple containers 100.

[0107] In one embodiment, such as Figure 14 and Figure 15 As shown, the heavy-duty transfer device also includes a support mechanism 4, which is mounted on the lifting and traveling beam 1 and is adapted to abut against the side of the container 100. When the lifting and traveling beam 1 lifts the container 100 and moves the container 100, the support mechanism 4 can be used to provide auxiliary support for the container 100, thereby improving the stability and safety of the container 100 during the transfer process.

[0108] For details, please refer to Figure 14 and Figure 15 One end of the support mechanism 4 is hinged to the beam 11, and the other end of the support mechanism 4 forms an abutment surface. When the transfer device is in operation, the support mechanism 4 rotates to extend out of the beam 11 and abuts against the side of the container 100 to provide further support for the container 100; when the transfer device is in storage, the support mechanism 4 rotates to be close to the beam 11 to reduce the space occupied.

[0109] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
