Description

Technical Field

[0001] This utility model pertains to auxiliary support devices, specifically a support structure suitable for container loading and unloading devices. Background Technology

[0002] A modular work area (or modular container) is a box-shaped work space with fixed or expandable volume, possessing protective properties and suitable for transport, formed by organically combining various sturdy materials. Similar to shipping containers, modular work areas are standardized with reference to container standards. Depending on the needs, different equipment and devices are loaded. Compared to shipping containers, modular work areas offer higher reliability, electromagnetic compatibility, airtightness, and thermal insulation. Currently, modular work areas both domestically and internationally can be broadly categorized into expandable and non-expandable types. Expandable work areas can be further classified according to their structural methods, such as pull-out and four-panel linkage types. Non-expandable work areas can be classified by size, such as four-meter and six-meter units. Based on the mode of transport, they can be divided into road transport and rail transport; road transport uses right-angled units, while rail transport uses angled units.

[0003] In addition, there are different loading and unloading methods for modular shelters in transport vehicles. One type has side panels that can be flipped down, while the other type has fixed left and right side panels that cannot be flipped down. In the latter case, external tools such as cranes and forklifts are needed to assist in loading and unloading the modular shelters, which brings many inconveniences to the loading and unloading work. Therefore, it is necessary to optimize and improve the loading and unloading devices for modular shelters.

[0004] Chinese patent application publication number CN105270781A discloses a mechanical container loading and unloading transfer tool and system. It includes a traveling assembly, an intermediate connecting assembly, and a container connecting assembly that can be fixedly connected to the container body. The intermediate connecting assembly is sleeved on the column of the traveling assembly and connected to the container connecting assembly. The intermediate connecting assembly and the container connecting assembly are driven by a lifting power device of either the intermediate connecting assembly or the traveling assembly, and move along the length of the column. However, the structure of this patent is relatively complex and cannot achieve the functions of loading containers sequentially onto off-road vehicles or side-loading them onto railway flatbeds.

[0005] Therefore, it is urgent to optimize the support structure of the loading and unloading device, improve its compatibility with container cabins, adapt to different styles and specifications of container cabins, and enable rapid installation and disassembly to improve the convenience of installation and disassembly with container cabins.

[0007] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0008] A support structure for loading and unloading a container includes an installation bracket, a connecting bracket, and a lifting bracket. The installation bracket is detachably connected to the container. One end of the connecting bracket is rotatably connected to the installation bracket, and the other end, which is opposite to it, is integrally connected to the lifting bracket and moves together with it. The lifting bracket allows for vertical position adjustment of the connecting bracket, thereby driving the position change of the container, which is fixed integrally with the connecting bracket, to achieve loading and unloading of the container. The connecting bracket, which is rotatably connected to the installation bracket, allows for convenient adjustment of the positional relationship between the support structure and the container to be loaded or unloaded, enabling flexible loading and unloading of the container. It can be adapted to container holds of different styles and specifications, and can achieve rapid installation and disassembly, thereby improving the convenience of installation and disassembly with container holds.

[0009] Furthermore, the mounting bracket includes a mounting frame, a support frame, at least one locking pin, and at least one locking lug. The mounting frame is a profile with a receiving cavity. The support frame is detachably nested inside the mounting frame and fixed to the mounting frame as a whole by the locking pin, and is configured to move together. The locking pin passes through the side of the mounting frame and the support frame and is spaced apart along the length of the mounting frame. The locking lug is fixed at intervals on the support frame and located on the opposite end of the mounting frame.

[0010] Furthermore, the mounting bracket includes a body and at least two limiting grooves formed on the body. The body is a U-shaped profile with an opening on one side and a receiving cavity. The limiting grooves are formed at intervals on the end sides of both sides of the body and have open grooves for internal limiting.

[0011] Furthermore, the limiting groove has an outer opening and an L-shaped groove inside.

[0012] Furthermore, the lock lug includes a connecting hole and at least one limiting hole formed on the lug, wherein the limiting holes are arranged at axial intervals on a concentric arc with the connecting hole as the axis.

[0013] Furthermore, the connecting bracket includes a connecting plate, at least one connecting arm, at least two lugs, and a pin. One end of each connecting arm is fixed to the end side of the connecting plate at intervals, and the other end of each arm extends in a direction perpendicular to the connecting plate. The lugs are located at the ends of the connecting arms, at the far end away from the connecting plate. The pin is detachably disposed through the lugs and extends along the length of the connecting plate.

[0014] Furthermore, the lifting support includes a support rod and a transmission mechanism, the transmission mechanism being sleeved on the support rod and drivably connected to the support rod.

[0015] Furthermore, the transmission mechanism includes a drive motor, a rack sleeve, and a reducer that are connected as a whole and co-operated, wherein the rack sleeve is fixed on the reducer and communicates with the inside of the reducer; the drive motor is connected to the reducer as a whole and drives the reducer.

[0016] Furthermore, it also includes a traveling mechanism disposed at the bottom end of the lifting support and movably disposed with the lifting support. The traveling mechanism includes a fixed frame, a support and traveling wheels, wherein the traveling wheels are rotatably disposed at the bottom end of the support; the fixed frame is disposed at the top end of the support, fixed to the support as a whole, and moved together with it.

[0017] Furthermore, the walking mechanism also includes a rotating disk disposed between the fixed frame and the support, the rotating disk being rotatably disposed from the fixed frame.

[0018] The support structure of the loading and unloading device provided in the above embodiments, through the connecting frame formed by the connecting plate and connecting arm, can load and withstand uncertain loads. The pin and ear seat work together to facilitate the disassembly, assembly, and locking of the connecting bracket and the mounting bracket. The provided connecting bracket, through the connection hole and the pin, achieves a rotatable connection with the connecting bracket, and works with the limiting hole to achieve reliable fixation at a certain angle. Through the transmission mechanism connected to the support rod, the positional relationship between the support rod and the transmission mechanism can be quickly and easily realized, thereby driving the connecting bracket, which is fixed integrally with the lifting bracket and moves in tandem, thus changing the position of the container fixed on the mounting bracket and completing the loading and unloading of the container. The driving force of the drive motor can be transmitted to the rack sleeve through the reducer, and through the rack sleeve connected to the inside of the reducer, it can... After the teeth on the side of the support rod, which is fitted inside the rack sleeve, engage, a driving force is generated, enabling the entire transmission mechanism to reciprocate along the rack of the support rod. The driving force of the drive motor can be transmitted to the rack sleeve through the reducer. The rack sleeve, which is connected to the reducer, can engage with the teeth on the side of the support rod, which is fitted inside the rack sleeve, to generate a driving force, enabling the entire transmission mechanism to reciprocate along the rack of the support rod. Through the rack machined on the support rod and the meshing structure set inside the transmission structure, the positional relationship between the transmission structure and the support rod can be stably and quickly realized, which has the advantages of simple structure and stable and reliable drive. By nesting the support frame inside the cavity of the mounting frame, the force on the mounting frame can be evenly distributed, avoiding stress concentration at the stress points between the support frame and the mounting frame, and improving the stability and safety of the connection.

[0026] like Figure 1As shown in the partial exemplary embodiment, a support structure for a loading and unloading device is provided for loading and unloading a container 100. The support structure includes a mounting bracket 10, a connecting bracket 20, and a lifting bracket 30. The mounting bracket 10 is detachably connected to the container 100. One end of the connecting bracket 20 is rotatably connected to the mounting bracket 10, and the other end, opposite to it, is integrally connected to the lifting bracket 30 and moves together with it. Thus, the lifting bracket allows for vertical position adjustment of the connecting bracket, thereby driving a change in the position of the container fixed to the connecting bracket, enabling loading and unloading of the container. The connecting bracket, rotatably connected to the mounting bracket, allows for convenient adjustment of the positional relationship between the support structure and the container to be loaded or unloaded, enabling flexible loading and unloading of the container. It is adaptable to different styles and specifications of container holds, allowing for rapid installation and disassembly, thus improving the convenience of installation and disassembly with container holds.

[0027] Preferably, such as Figure 2 As shown, the mounting bracket 10 includes a mounting frame 11, a support frame 12, at least one locking pin 13, and at least one locking lug 14. The mounting frame 11 is a profile with a receiving cavity. The support frame 12 is detachably nested inside the mounting frame 11 and fixed integrally with the mounting frame 11 by the locking pin 13, and is configured to move together. The locking pin 13 passes through the sides of the mounting frame 11 and the support frame 12, and is spaced apart along the length of the mounting frame 11. The locking lug 14 is fixed at intervals on the support frame 12, located on the opposite end of the mounting frame 11. Therefore, by nesting the support frame inside the cavity of the mounting frame, the force on the mounting frame can be evenly distributed, avoiding stress concentration at the stress points between the support frame and the mounting frame, and improving the stability and safety of the connection.

[0028] Preferably, the mounting bracket 11 includes a body 111 and at least two limiting grooves 112 formed on the body 111. The body 111 is a U-shaped profile with an opening on one side and a cavity for receiving the cavity. The limiting grooves 112 are spaced apart on the end sides of the body 111 and have open grooves for internal limiting. Specifically, the limiting groove 112 has an outer opening and an L-shaped bend in the groove inside; further, the opening direction of the limiting groove 112 is consistent with the opening direction of the body 111. Preferably, the internal cavity structures of the limiting grooves 112 are identical. Thus, when the locking pin is fixed to the support bracket, it can be inserted from the opening of the limiting groove and slide along the L-shaped path to the corner, forming a stable mechanical support under the combined action of gravity.

[0029] Optionally, to facilitate quick assembly and locking between the mounting bracket 10 and the connecting bracket 20, the locking lug 14 includes a connecting hole 141 and at least one limiting hole 142 formed on the lug. The limiting holes 142 are axially spaced on a concentric arc with the connecting hole 141 as the axis. Thus, the connecting hole 141 cooperates with the pin to achieve a rotatable connection with the connecting bracket 20, and works together with the limiting hole 142 to achieve reliable fixation at a certain angle.

[0030] Optionally, such as Figure 3 As shown, the connecting bracket 20 is welded from a panel and supporting ribs, thus possessing sufficient rigidity to load and withstand uncertain loads. Specifically, the connecting bracket 20 includes a connecting plate 21, at least one connecting arm 22, at least two lugs 23, and a pin 24. One end of each connecting arm 22 is fixed to the end side of the connecting plate 21 at intervals, while the other end extends perpendicular to the connecting plate 21. The lugs 23 are located at the ends of the connecting arms 22, at the far end away from the connecting plate 21. The pin 24 is detachably disposed through the lugs 23 and extends along the length of the connecting plate 21. Specifically, the lugs 23 are lugs with a central cavity and protruding ears on both sides. The connecting frame formed by the connecting plate and connecting arms can load and withstand uncertain loads. Through the combined action of the pins and lugs, the connecting bracket and the mounting bracket can be easily disassembled, assembled, and locked.

[0031] To facilitate quick disassembly and locking with the mounting bracket 10, the pin 24 includes at least one fixing pin 241 and at least one limiting pin 242. The fixing pin 241 and the limiting pin 242 pass through the ear seat 23 and are detachably connected to the ear seat 23.

[0032] In addition, to improve the overall rigidity of the connecting bracket 20 and enhance its load-bearing capacity, it also includes reinforcing components added at the connection points of the connecting plate 21, connecting arm 22, and ear seat 23, such as one or a combination of reinforcing plates, support crossbars, and reinforcing ribs.

[0033] In summary, the connecting bracket provided by this utility model patent achieves a rotatable connection with the connecting bracket through the cooperation of the connecting hole and the pin shaft, and works together with the limiting hole to achieve reliable fixation at a certain angle; the connecting frame formed by the connecting plate and the connecting arm can load and withstand uncertain loads, and through the joint action of the pin shaft and the ear seat, the connecting bracket and the mounting bracket can be easily disassembled, assembled and locked.

[0034] like Figure 1 and Figure 4As shown, the lifting support 30 includes a support rod 31 and a transmission mechanism 32. The transmission mechanism 32 is sleeved on the support rod 31 and is drivably connected to the support rod 31. Thus, through the transmission mechanism drivably connected to the support rod, the positional relationship between the support rod and the transmission mechanism can be quickly and conveniently realized, thereby driving the connecting support that is fixed to the lifting support and moves together with it, thereby changing the position of the container fixed on the mounting support and completing the loading and unloading of the container.

[0035] Optionally, a rack and pinion meshing structure is used between the support rod 31 and the transmission structure 32. For example, a rack is machined on the surface of the support rod 31, extending along the length of the support rod 31; the transmission structure 32 is fitted inside the support rod 31 and has a moving component that meshes with the rack. Specifically, the rack is a circular rack assembly; the transmission structure 32 consists of an AC motor, a planetary reducer and gearbox, an RV reducer, etc. Thus, by using the rack machined on the support rod and the meshing structure inside the transmission structure, the positional relationship between the transmission structure and the support rod can be stably and quickly realized, offering advantages such as simple structure and stable and reliable drive.

[0036] Specifically, the transmission mechanism 32 includes a drive motor 321, a rack sleeve 322, and a reducer 323 that are connected as a whole and co-operated. The rack sleeve 322 is fixed on the reducer 323 and is connected to the inside of the reducer 323. The drive motor 321 is connected to the reducer 323 as a whole and is driven by the reducer 323. Thus, the driving force of the drive motor can be transmitted to the rack sleeve through the reducer. Through the rack sleeve, which is connected to the inside of the reducer, the drive motor can engage the teeth on the side of the support rod that is sleeved inside the rack sleeve to generate a driving force, thereby realizing the reciprocating motion of the entire transmission mechanism along the rack of the support rod.

[0037] Optionally, to facilitate self-locking of the loading and unloading device during lifting and lowering, thereby enabling the device to stop at any position during operation, the reducer 323 employs a multi-stage reduction gear. Specifically, the reducer 323 is a two-stage reduction gear, where the first stage is a planetary reducer and the second stage is a worm gear reducer. Thus, employing a multi-stage reduction gear effectively slows down the loading and unloading process of the container, improving the stability and safety of the operation. Specifically, the reducer 323 is a worm gear reduction mechanism.

[0038] In summary, the driving force of the drive motor can be transmitted to the rack sleeve through the reducer. The rack sleeve, which is connected to the inside of the reducer, can engage with the teeth on the side of the support rod that are ringed inside the rack sleeve, generating driving force and enabling the entire transmission mechanism to reciprocate along the rack of the support rod. Through the rack machined on the support rod and the meshing structure set inside the transmission structure, the positional relationship between the transmission structure and the support rod can be stably and quickly realized, which has the advantages of simple structure and stable and reliable drive.

[0039] like Figure 1 and Figure 5 As shown, in order to realize the orientation switching of the loading and unloading device, a traveling mechanism 40 is also included, which is set at the bottom of the lifting bracket 30 and is movably arranged with the lifting bracket 30. The traveling mechanism 40 includes a fixed frame 41, a bracket 42 and traveling wheels 43. The traveling wheels 43 are rotatably set at the bottom of the bracket 42, and the fixed frame 41 is set at the top of the bracket 42, fixed to the bracket 42 as a whole, and moved together. Optionally, the traveling wheels 43 are double-row polyurethane rollers.

[0040] Furthermore, to enhance the flexibility and reliability of the direction switching process, a rotating disk 44 is also included, which is rotatably disposed between the fixed frame 41 and the bracket 42. Specifically, the rotating disk 44 is a hand-held rotating disk.

[0041] In summary, the support structure of the loading and unloading device provided in the above embodiments of this application has at least the following characteristics: the connecting frame, formed by the connecting plate and the connecting arm, can load and withstand uncertain loads; the connecting bracket and the mounting bracket can be easily disassembled, assembled, and locked through the joint action of the pin and the ear seat; the provided connecting bracket can be rotatably connected to the connecting bracket through the connecting hole and the pin, and can be reliably fixed at a certain angle through the action of the limiting hole; the transmission mechanism connected to the support rod can quickly and easily realize the positional relationship between the support rod and the transmission mechanism, thereby driving the connecting bracket, which is fixed to the lifting bracket and moves together with it, to change the position of the container fixed on the mounting bracket and complete the loading and unloading of the container; the driving force of the drive motor can be transmitted to the rack sleeve through the reducer, and through the internal communication device of the reducer... The rack sleeve, when engaged with the teeth on the side of the support rod inside the rack sleeve, generates a driving force, enabling the entire transmission mechanism to reciprocate along the rack of the support rod. The driving force of the drive motor is transmitted to the rack sleeve through a reducer. The rack sleeve, which is connected to the reducer, engages with the teeth on the side of the support rod inside the rack sleeve, generating a driving force and enabling the entire transmission mechanism to reciprocate along the rack of the support rod. Through the rack machined on the support rod and the meshing structure set inside the transmission structure, the positional relationship between the transmission structure and the support rod can be stably and quickly realized, with advantages such as simple structure and stable and reliable drive. By nesting the support frame inside the cavity of the mounting frame, the force on the mounting frame can be evenly distributed, avoiding stress concentration at the stress points between the support frame and the mounting frame, and improving the stability and safety of the connection.

[0042] The above description is merely a specific embodiment of this utility model. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
