[0032] As the background technology shows, with the continuous development of the economy, the degree of containerization in logistics and transportation is getting higher and higher, and the types of container loading and unloading equipment are also increasing. Common container loading and unloading equipment mainly includes quay cranes, terminal rubber-tired or rail-mounted gantry cranes, terminal container reach stackers, container handling vehicles, and container stackers, etc. When wheeled vehicles and tracked equipment are required to carry out lifting or unloading operations at container terminals, the required spreader size is large due to the limitations of berth and the size of the items to be lifted. It is not convenient to move and transport, and the spreader is not easy to disassemble after installation, which increases the operating cost and space required for lifting. Moreover, the stability of the spreader is easily affected by external factors such as wind during the lifting process.

[0033] The following combination Figures 1-8 The embodiments of this application will be described in detail below.

[0034] In view of this, such as Figures 1-3As shown, some embodiments of this application provide a modular container lifting and assembly spreader, including a lifting frame 1, connecting columns 2, and a pallet assembly 3. The lifting frame 1 includes multiple corner splicing parts 11, each corner splicing part 11 being located at a corner of the lifting frame 1. Adjacent corner splicing parts 11 are fixedly connected by connecting plate groups 12, or a support rod group 13 is provided between adjacent corner splicing parts 11, and the corner splicing parts 11 and the support rod group 13 are fixedly connected by connecting plate groups 12. The top and bottom ends of the connecting columns 2 are respectively connected to the lifting frame 1 and the pallet assembly 3. The pallet assembly 3 includes multiple pallet modules 31, adjacent pallet modules 31 are detachably connected, and each pallet module 31 is provided with a fastener 9, which is used to provide a fastening position.

[0035] Specifically, in this embodiment, a lifting device that can be assembled on-site into a frame structure using a lifting frame 1, connecting column 2, and pallet assembly 3 is capable of lifting and transferring items such as containers and transport vehicles. The lifting frame 1 is assembled from corner splicing parts 11 and support rod assembly 13 via connecting plate assembly 12 for connection with cranes and other lifting equipment. Adjacent pallet modules 31 are detachably connected, and multiple pallet modules 31 can be assembled into a pallet assembly 3 of the required size according to actual conditions, so as to realize the flexible use of the lifting device, solve the problem of inconvenient transportation caused by the large size of the lifting device, and facilitate transfer and carrying. After use, the lifting device can be disassembled to reduce its space occupation. The fasteners 9 set on the pallet module 31 can form corresponding fastening positions on the pallet assembly 3. The items supported by the pallet assembly 3 can be tied and fixed using the fasteners 9 and binding tools such as straps to ensure the stability of the lifting process and reduce the impact of external factors such as wind on the lifting process.

[0036] like Figure 2 and Figure 4 As shown, in some embodiments, the corner splicing member 11 is provided with a lifting block 4, the top of the lifting block 4 is provided with a long lifting hole 4A, and the bottom is provided with an observation hole 4B, which is connected to the long lifting hole 4A.

[0037] Specifically, in this embodiment, the lifting block 4 provides a lifting position for the lifting equipment, allowing it to be connected to the lifting equipment. During use, the bolt assembly at the end of the rigging on the lifting equipment is inserted into the elongated lifting hole 4A and tightened to connect the hanger 1 to the lifting equipment. The elongated lifting hole 4A is designed to allow the bolt assembly used for connection and fixation to slide within the hole, facilitating the adjustment of the connection position between the hanger 1 and the lifting equipment, thus ensuring the stability of the hanger 1 installation. An observation hole 4B connected to the elongated lifting hole 4A is provided at the bottom of the lifting block 4, facilitating the observation of the rigging installation and ensuring a stable and smooth installation process.

[0038] like Figure 4As shown, in some embodiments, the corner splice 11 includes a top rod 111, a bottom rod 112, and a diagonal brace 113. There are two top rods 111 and two bottom rods 112. One end of each top rod 111 is fixedly connected to the lifting block 4, and the other end of each is fixedly connected to a set of connecting plate groups 12. The two bottom rods 112 are correspondingly located below the two top rods 111, and one end of each bottom rod 112 is connected to the other, and the other end of each is fixedly connected to a set of connecting plate groups 12. The two ends of the diagonal brace 113 are fixedly connected to the side wall of the lifting block 4 and the corresponding bottom rod 112, respectively.

[0039] Specifically, in this embodiment, the corner splicing component 11 is composed of two sets of top rods 111, two sets of bottom rods 112, and diagonal bracing rods 113. The bottom rods 112 are located below the top rods 111, thereby forming a layered support structure for the corner splicing component 11. The ends of each top rod 111 and each bottom rod 112 are respectively connected to the connecting plate group 12, so as to facilitate the assembly and splicing of the corner splicing component 11 and the support rod group 12. Furthermore, by providing diagonal bracing rods 113 in the corner splicing component 11, the corner splicing component 11 can be supported and reinforced, providing its overall robustness.

[0040] Optionally, to ensure the firmness of the corner splice 11 itself and its connection with the lifting block 4, the top rod 111 and the connecting plate assembly 12, the top rod 111 and the lifting block 4, the bottom rod 112 and the bottom rod 112, and the bottom rod 112 and the connecting plate assembly 12 can all be connected by welding to ensure the overall strength of the corner splice 11.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, bolt fasteners 5 are provided between the top end of the connecting column 2 and the hanger 1, between the bottom end of the connecting column 2 and the tray assembly 3, between adjacent tray modules 31, and in the connecting plate group 12.

[0042] Specifically, in this embodiment, bolts and fasteners 5 are used to connect and fix the connecting plates 12 that abut against each other, so that the adjacent corner splice pieces 11 and the corner splice pieces 11 and the support rod group 13 are locked together; the adjacent pallet modules 31 can also be assembled into pallet assembly 3; in addition, the two ends of the connecting column 2 can also be fixedly connected to the assembled hanger 1 and pallet assembly 3 using bolts and fasteners 5, so as to ensure that the spliced ​​lifting device has good firmness, and the bolts and fasteners 5 are highly versatile and low in cost, which is convenient for workers to carry out construction. Therefore, it is convenient to disassemble and install the lifting device, effectively reducing cost input.

[0043] like Figure 2 and Figure 4As shown, in some embodiments, the connecting plate assembly 12 includes two connecting plates 121. Each connecting plate 121 is connected to the end of the corner splice 11 or the support rod assembly 13. The connecting plate 121 has a connecting hole 121A. Bolts and fasteners 5 are inserted into the connecting hole 121A and are used to lock and fix the two abutting connecting plates 121.

[0044] Specifically, the connecting plate group 12 can be used to splice and assemble adjacent corner splice pieces 11 or corner splice pieces 11 and support rod group 13, thereby realizing the assembly of the hanger 1. During the assembly, the two adjacent connecting plates 121 abut against each other and the connecting holes 121A of each pair correspond to each other. At this time, the bolt fasteners 5 are inserted into the connecting holes 121A of the two connecting plates 121 and tightened, and the connecting plates 121 are fixed together by the bolt fasteners 5.

[0045] In such Figure 1 and Figure 2 As shown, in some embodiments, the support rod assembly 13 includes an upper support rod 131 and a lower support rod 132. Both ends of the upper support rod 131 and both ends of the lower support rod 132 are connected to the corner splice 11 through the connecting plate assembly 12. The upper support rod 131 is located above the lower support rod 132 and the two are parallel to each other. The lower support rod 132 is connected to the top of the connecting column 2.

[0046] Specifically, by using parallel upper support rods 131 and lower support rods 132 to splice and assemble with corner splicing parts 11, the assembled hanger 1 has good stability. At the same time, the ends of the upper support rods 131 and lower support rods 132 are respectively provided with connecting plates 121 for connecting with corner splicing parts 11, so as to facilitate the assembly between the support rod group 13 and the corner splicing parts 11, and also to facilitate the transfer and transportation after disassembly.

[0047] like Figure 2 As shown, in some embodiments, both the corner splice 11 and the lower support rod 132 are provided with an assembly part 6. The assembly part 6 and the end of the connecting column 2 are respectively provided with an assembly hole 6A. The bolt fastener 5 passes through the assembly hole 6A and the top end of the connecting column 2 is fixed to the corner splice 11 or the lower support rod 132 by the bolt fastener 5.

[0048] Specifically, by providing an assembly part 6 on the bottom rod 112 and the lower support rod 132 of the corner splice 11, a connection position can be provided for the bolt fastener 5 so that the top of the connecting column 2 can be assembled and connected with the hanger 1. During the assembly process, the bolt fastener 5 is sequentially inserted into the top of the connecting column 2 and the assembly hole 6A of the assembly part 6, and the bolt fastener 5 is tightened, thereby fixing the connecting column 2 and the hanger 1 together.

[0049] like Figure 3 and Figure 6 As shown, in some embodiments, the tray module 31 is set as a cuboid, that is, all the tray modules 31 used are set as the same detachable cuboid, so as to improve the versatility of the tray modules 31 used, reduce the assembly difficulty, and ensure the splicing efficiency.

[0050] like Figure 3 and Figure 6 As shown, in some embodiments, the tray module 31 has a slot 7, and the side wall of the slot 7 has an assembly hole 7A. The bolt fastener 5 passes through the assembly hole 7A and is used to lock and fix adjacent tray modules 31.

[0051] Specifically, adjacent pallet modules 31 can be assembled and connected using bolt fasteners 5 to form pallet assembly 3. The required dimensions can be spliced ​​according to actual needs. By opening slots 7 on the pallet modules 31, it is easy to install locking bolts and insert them into the assembly holes 7A. It is also easy to tighten the bolt fasteners 5 so that workers can disassemble and assemble them.

[0052] Optionally, after the pallet assembly 3 is assembled, a rubber plug or other filler can be inserted into the slot 7 to prevent external dust from accumulating in the slot 7 and affecting the subsequent disassembly of the pallet assembly 3.

[0053] like Figure 3 and Figure 6 As shown, in some embodiments, the fastener 9 includes a bent plate 91 and a fastening ring 92. The bent plate 91 is connected to the top surface of the tray module 31, and a cavity is formed between the bent plate 91 and the tray module 31. The fastening ring 92 is rotatably disposed in the cavity. At least two sets of fasteners 9 are provided on the top of each tray module 31.

[0054] Specifically, the fasteners 9, together with the binding tools, are used to bind and secure the items supported on the pallet assembly 3 to ensure stability during the hoisting process. The binding straps and other binding tools are attached to the binding ring 92 to provide a binding position for the binding tools. The binding ring 92 is rotatably set in the cavity so that the binding ring 92 can change with the binding direction of the binding straps to ensure that the items on the pallet assembly 3 are firmly fixed. Multiple sets of fasteners 9 are provided to meet the binding requirements of items of different sizes.

[0055] Specifically, by setting multiple sets of fasteners 9 on the pallet module 31, appropriate fastening positions can be selected for different hoisted items to ensure the items are securely fixed.

[0056] like Figure 3 and Figure 8As shown, in some embodiments, the end of the pallet assembly 3 is also provided with a ramp module 8. The ramp module 8 has a transfer ramp surface, and the transfer ramp surface has an installation groove 8A. The installation groove 8A has a through hole 8B. Bolts and fasteners 5 are sequentially inserted into the through hole 8B and the assembly hole 7A, and the ramp module 8 is connected to the pallet assembly 3 by the bolts and fasteners 5.

[0057] Specifically, by providing a ramp module 8 with a transfer ramp at the end of the pallet assembly 3, it is easy for vehicles to drive onto the pallet assembly 3. The ramp module 8 also has an installation groove 8A, which facilitates assembly operations by workers. When it is necessary to install it onto the pallet assembly 3, the ramp module 8 is placed against the pallet assembly 3, and the bolts and fasteners 5 are correspondingly inserted into the through hole 8B and the assembly hole 7A. The ramp module 8 is connected to the pallet assembly 3 by the bolts and fasteners 5, which are secure and easy to install and remove.

[0058] In some embodiments, this application provides a method for assembling a modular container crane spreading assembly, the assembly method being as follows:

[0059] Assemble the hanger 1: Lock and fix adjacent corner splice pieces 11, or corner splice pieces 11 and support rod assembly 13, through connecting plate assembly 12;

[0060] Assemble pallet assembly 3: make the side walls of adjacent pallet modules 31 abut against each other, and lock and fix the adjacent pallet modules 31 together;

[0061] Assemble the lifting device: fix the top of the connecting column 2 to the lifting frame 1, and fix its bottom to the pallet assembly 3.

[0062] Specifically, the lifting device in this embodiment is assembled from modular components. Before assembly, the lifting frame 1 and the pallet assembly 3 need to be assembled separately. When assembling the lifting frame 1, the connecting plates 121 in adjacent corner splice parts 11 are brought together, and the connected plate assembly 12 is locked and fixed using bolts and fasteners 5, thus completing the assembly between the corner splice parts 11. Similarly, the connecting plates 121 at the ends of the upper support rod 131 and lower support rod 132 in the support rod assembly 13 are brought together with another connecting plate 121 on the corner splice part 11, and the connected plate assembly 12 is locked and fixed using bolts and fasteners 5, thus completing the assembly of the lifting frame 1. Conversely, the sides of the pallet modules 31 are made to abut against each other, and the assembly holes 7A on adjacent pallet modules 31 are aligned. The bolts and fasteners 5 are inserted into the assembly holes 7A through the slots 7. By tightening the bolts and fasteners 5, the pallet assembly 3 is assembled. The bolts and fasteners 5 are inserted into the assembly holes 6A of the assembly part 6. The top of the connecting column 2 is locked onto the hanger 1 by the bolts and fasteners 5 in the assembly holes 6A. At the same time, the bolts and fasteners 5 are inserted into the assembly holes 7A on the side of the pallet assembly 3. The bottom of the connecting column 2 is fixed onto the pallet assembly 3 by the bolts and fasteners 5, thereby completing the assembly of the hanger.
