[0001] This application relates to the field of container spreader technology, and in particular to a portable modular container crane adapter. Background Technology

[0002] With the rapid development of my country's economy, the degree of containerization in logistics and transportation is increasing, and the application of various container handling equipment is also growing. Common container handling equipment mainly includes quay cranes, terminal rubber-tired or rail-mounted gantry cranes, terminal container reach stackers, container handling vehicles, and container stackers. Due to the large size of containers, the dimensions of the handling rigs required are also large. Therefore, existing rigs are inconvenient to move and transport due to their size limitations, and they are not easy to disassemble after use, resulting in poor flexibility and high lifting costs. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose a portable modular container crane adapter.

[0004] To achieve the above objectives, this application provides a portable modular container crane adapter, comprising a frame, lifting blocks, and lifting components, wherein:

[0005] The frame includes multiple corner members, each of which is located at a corner of the frame; adjacent corner members are fixedly connected by a connecting plate, or a support beam group is provided between adjacent corner members, and the corner members and the support beam group are fixedly connected by the connecting plate.

[0006] The lifting block is located on the top of the corner member, and the lifting block is used to provide an installation position for the lifting equipment;

[0007] Each corner member is provided with a lifting component at its bottom. The corner member has multiple positioning points along the length of the frame. The lifting component and the positioning points are detachably connected.

[0008] Furthermore, the corner member includes a top beam, a bottom beam, and a diagonal bracing beam. There are two top beams and two bottom beams. One end of each top beam is fixedly connected to the lifting block, and the other end is fixedly connected to the connecting plate. Two bottom beams are correspondingly located below the two top beams, and one end of each bottom beam is fixedly connected to the other. The other ends of each bottom beam are fixedly connected to a connecting plate. The two ends of the diagonal bracing beam are fixedly connected to the lifting block and any set of bottom beams, respectively.

[0009] Furthermore, the extension lines of the two top beams and the extension lines of the two bottom beams are both designed to be perpendicular to each other.

[0010] Furthermore, bolt fasteners are provided between the corner member and the lifting member, and between the connecting plates.

[0011] Furthermore, the top of the lifting block is provided with a lifting hole, and the bottom of the block is provided with an observation hole, which is connected to the lifting hole.

[0012] Furthermore, the hoisting hole is designed as an elongated hole.

[0013] Furthermore, the support beam assembly includes two parallel support beams, the end of each support beam being fixedly connected to the connecting plate pair, wherein one support beam is connected to the top beam through the connecting plate pair, and the other support beam is connected to the bottom beam through the connecting plate pair.

[0014] Furthermore, the connecting plate pair includes two connecting plates, each of which is connected to the end of the corner member or the support beam assembly. Each connecting plate has a connecting hole, and a bolt fastener passes through the connecting hole to lock and fix the two abutting connecting plates.

This facilitates carrying and transportation, reducing operating costs. Furthermore, the bottom of the frame is equipped with detachable lifting components, which are convenient to assemble onto the frame on-site. The installation position of these components on the corner members can also be adjusted according to the actual working conditions, so that the slings secured to the lifting components are in a vertical state or the angle between them and the vertical direction is minimized, thereby minimizing the tension on the slings and ensuring the stability and safety of the entire lifting operation.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0026] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] As the background technology states, with the continuous development of the economy, the degree of containerization in logistics and transportation is increasing, 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 lifting vehicles and tracked equipment are needed for 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. This makes it inconvenient to carry and transport, and the spreader is not easy to disassemble after installation, increasing the operating cost and space required for lifting. Moreover, since the size of the containers being lifted also varies, when lifting larger and heavier items, there will be an angle between the slings fixed to the jack and the vertical direction. The larger the angle, the greater the tension that the slings need to withstand. Over time, this will damage the slings and may even cause the items being lifted to tilt or shift during lifting, affecting the stability and safety of the entire lifting process.

[0028] The following is in conjunction with the appendix Figures 1-5 The embodiments of this application will be described in detail below.

[0029] like Figure 1As shown, in some embodiments, this application provides a portable combined container crane adapter, including a frame 1, a lifting block 2, and a lifting component 3. The frame 1 includes multiple corner members 11, each corner member 11 being located at a corner of the frame 1. Adjacent corner members 11 are fixedly connected by connecting plates 12, or a support beam group 13 is provided between adjacent corner members 11, and the corner members 11 and the support beam group 13 are fixedly connected by connecting plates 12. The lifting block 2 is located on the top of the corner member 11, and the lifting block 2 is used to provide an installation position for the lifting equipment. A lifting component 13 is provided at the bottom of each corner member 11, and the corner member has multiple positioning points along the length of the frame 1. The lifting component 13 and the positioning points are detachably connected.

[0030] Specifically, in this embodiment, the hanger is assembled from corner members 11 and support beams 13 via connecting plates 12, facilitating carrying and transportation, and making it easy to transport the frame 1 to the site for assembly and splicing. The top of the corner members 11 is equipped with a lifting block 2 to provide an installation position for lifting equipment such as truck cranes and crawler cranes, ensuring a secure connection between the hanger and the lifting equipment. Each corner member 11 has a lifting component 3 at its bottom to provide a securing position for slings and other lifting equipment. According to lifting specifications, the angle between the sling and the vertical direction during lifting must be within the specified range and should not be too large to avoid excessive stress on the slings. To enhance its fatigue resistance, the direction in which the corner member 11 and the support beam group 13 in frame 1 are connected is set to the length direction of frame 1. By setting the lifting member 3 and the corner member 11 to be detachably connected, the installation position of the lifting member 3 at the bottom of the corner member 11 can be adjusted along the length direction of frame 1. This allows the installation position of the lifting member 3 on the corner member 11 to be adjusted according to the actual size of the object being lifted, so that the angle between the sling tied to the lifting member 3 and the vertical direction is minimized after adjustment. This reduces the tension on the sling, extends its service life, avoids deviation during lifting, and ensures the stability and safety of the lifting process.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the corner member 11 includes a top beam 111, a bottom beam 112, and a diagonal brace 113. There are two top beams 111 and two bottom beams 112. One end of each top beam 111 is fixedly connected to the lifting block 2, and the other end is fixedly connected to the connecting plate pair 12. The two bottom beams 112 are correspondingly located below the two top beams 111, and one end of the two bottom beams 112 is fixedly connected to each other. The other ends of the two bottom beams 112 are respectively fixedly connected to a connecting plate pair 12. The two ends of the diagonal brace 113 are respectively fixedly connected to the lifting block 2 and any set of bottom beams 112. The extension lines of the two top beams 111 and the extension lines of the two bottom beams 112 are both set to be perpendicular to each other.

[0032] Specifically, in this embodiment, the corner member 11 consists of two top beams 111 connected to the lifting block 2, two bottom beams 112 connected at their ends, and a diagonal brace 113, forming a single-layer splicing structure. The bottom beam 112 is detachably connected to the lifting component 3 to provide an installation position for the lifting component 3. The two ends of the diagonal brace 113 are connected to the lifting block 2 and the bottom beam 112, respectively, to reinforce the top beams 111 and the bottom beams 112 in the corner member 11 and improve the overall stability. The ends of each top beam 111 and bottom beam 112 are connected to the connecting plate pair 12, which facilitates splicing and assembly between adjacent corner members 11 or between the corner member 11 and the support beam group 13.

[0033] Optionally, to ensure the stability of the corner member 11 itself and its connection with the lifting block 2, the top beam 111 and the connecting plate pair 12, the top beam 111 and the lifting block 2, the bottom beam 112 and the bottom beam 112, and the bottom beam 112 and the connecting plate pair 12 are all connected by welding to ensure that the corner member 11 formed has good strength.

[0034] like Figure 1 As shown, in some embodiments, bolts 4 are provided between the corner member 11 and the lifting member 3, and on the connecting plate pair 12. Since the bolts 4 have advantages such as low cost, good versatility, simple fastening method, convenient operation and reusability, the connecting plate pair 12 can be locked and fixed by using bolts 4, so that adjacent corner members 11 or corner members 11 and support beam group 13 can be assembled, ensuring that the assembled hanger has good firmness, and the hanger is also easy to disassemble after use; and the lifting member 3 is fixed to the corner member 11 by bolts, which is convenient for disassembly and installation, and also convenient for adjustment to the appropriate installation position.

[0035] like Figure 3 As shown, in some embodiments, the top of the lifting block 2 is provided with a lifting hole 2a, and the bottom is provided with an observation hole 2b, and the observation hole 2b is connected to the lifting hole 2a; the lifting hole 2a is a long hole.

[0036] Specifically, in this embodiment, the lifting block 2 provides an installation position for the lifting equipment, allowing it to be connected to the working end of the lifting equipment. In use, the bolt assembly at the working end of the lifting equipment is inserted into the strip-shaped lifting hole 2a and tightened to connect the hanger to the lifting equipment. The lifting hole 2a is an elongated hole, allowing the bolt assembly used for fixing to slide along the hole, adjusting the connection position between the hanger and the lifting equipment, and ensuring that the entire hanger is firmly fixed to the lifting equipment. By providing an observation hole 2b at the bottom of the lifting block 2 that communicates with the lifting hole 2a, it is convenient to observe the fixing status of the frame 1, and also convenient to tighten the bolt assembly.

[0037] like Figure 1 As shown, the support beam assembly 13 includes two parallel support beams 131. The end of each support beam 131 is fixedly connected to the connecting plate pair 12. One support beam 131 is connected to the top beam 111 through the connecting plate pair 12, and the other support beam 131 is connected to the bottom beam 112 through the connecting plate pair 12.

[0038] Specifically, parallel support beams 131 are spliced ​​with two corner members 11 to ensure the assembled frame 1 has good stability. At the same time, each end of the support beam 131 is provided with a connecting plate 121 for connecting with the corner member 11, which facilitates the assembly of the support beam assembly 13 and the corner member 11, and also facilitates the transfer and transportation after disassembly.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the connecting plate pair 12 includes two connecting plate members 121. Each connecting plate member 121 is connected to the end of the corner member 11 or the support beam group 13. The connecting plate member 121 has a connecting hole 12a. The bolt fastener 4 passes through the connecting hole 12a and is used to lock and fix the two abutting connecting plate members 121.

[0040] Specifically, the connecting plate pair 12 can be used to splice adjacent corner members 11, or corner members 11 and support beam group 13, to realize the assembly of frame 1 in the hanger. During assembly, adjacent connecting plates 121 are abutted against each other and their respective connecting holes 12a correspond to each other. Bolts and fasteners 4 are inserted into the connecting holes 12a of the two connecting plates 121 and tightened to lock and fix the connecting plate pair 12 with the bolts and fasteners 4.

[0041] like Figures 1-4 As shown, the lifting component 3 includes a lifting ring seat 31 and a lifting ring 32. The lifting ring seat 31 is detachably connected to the corner member 11, and a through cavity is provided through the lifting ring seat 31, in which the lifting ring 32 is rotatably disposed. The lifting ring seat 31 and the corner member 11 in the lifting ring 32 component are detachably connected to facilitate the disassembly and assembly of the lifting component 3 and the corner member 11, and also facilitate the adjustment of the position of the lifting component 3. The lifting ring 32 can rotate within the through cavity so that the sling fastened to the lifting ring 32 can be finely rotated and adjusted.

[0042] like Figure 5As shown, in some embodiments, the lifting ring seat 31 is provided with mounting holes 3a, and the bottom beam 112 is provided with a plurality of adjustment holes 3b corresponding to the positioning points evenly along the length direction of the frame 1. Bolts and fasteners 4 are sequentially inserted into the mounting holes 3a and adjustment holes 3b, and the lifting ring seat 31 is locked to the bottom beam 112 by the bolts and fasteners 4.

[0043] Specifically, in some embodiments, by opening mounting holes 3a on the lifting ring seat 31 and adjusting holes 3b on the bottom beam 112 of the corner member 11, the lifting ring seat 31 is fixed to the frame 1 using bolt fasteners 4, thereby realizing the assembly and connection of the lifting component 3; and multiple sets of adjusting holes 3b are opened along the length direction of the frame 1, thereby forming corresponding installation areas on the bottom beam 112 to provide different installation positions for the lifting ring seat 31. The position of the lifting component 3 at the bottom of the corner member 11 is adjusted according to the size of the actual lifted item, so that the sling fastened to the lifting ring 32 is in a vertical state, or the angle between it and the vertical direction is minimized, thereby reducing the tension on the sling and extending its service life, so as to ensure the stability and safety of the lifting process.
