Description

Technical Field

[0001] This utility model belongs to the field of container front-end lifting technology, specifically a non-standard lifting device based on container front-end lifting. Background Technology

[0002] A shipping container is a large cargo container designed specifically for reusable transport, characterized by its strength, rigidity, and standardized dimensions. The primary function of a container is to enable seamless transfer of goods between different modes of transport (such as sea, rail, road, and air) through standardized dimensions and structure, thereby improving transport efficiency and reducing costs. Containers can be categorized by cargo type, including dry cargo containers, bulk cargo containers, liquid cargo containers, and refrigerated containers. There are also special-purpose containers such as automotive containers and livestock containers.

[0003] A reach stacker, also known as a container reach crane, is a lifting device specifically designed for 20-foot and 40-foot international standard containers. It is primarily used for stacking containers and for horizontal transport in docks and yards. Compared to forklifts, reach stackers offer advantages such as flexibility, ease of operation, good stability, lower wheel pressure, higher stacking density, and higher yard utilization. They are particularly suitable for loading and unloading containers in small and medium-sized ports, railway transfer stations, and road transfer stations, and can also serve as auxiliary equipment for large container terminals.

[0004] like Figure 8 The diagram shows a front-end crane, which includes an engineering machinery chassis, a telescopic boom, and a container spreader 1. The container spreader 1 has four hooks 11 at the four corners of its lower part, which can be attached to the lifting holes on the upper part of the container. However, since the four hooks at the lower part of the traditional container spreader are in fixed positions, it is only suitable for lifting standard-sized containers. It cannot be flexibly applied to lifting non-standard-sized containers. Developing new container spreaders is costly, and it is very inconvenient to disassemble and replace container spreaders on a front-end crane. Utility Model Content

[0005] To address the issues that traditional container spreaders have fixed positions for the four hooks at the bottom, making them only suitable for lifting standard-sized containers and inflexible for lifting non-standard-sized containers, while developing new container spreaders is costly and disassembling and replacing them on a front-end crane is very inconvenient, this utility model provides a non-standard lifting device based on a container front-end crane.

[0006] This utility model is achieved through the following technical solution:

[0007] A non-standard lifting device based on a container front-end crane includes a lifting connecting frame. A bidirectional hydraulic cylinder is positioned and installed in the middle of the lifting connecting frame. The upper parts of both ends of the lifting connecting frame have lifting holes that can be hooked onto the hooks of the container spreader. Rotating columns are vertically rotatably installed at both ends of the lifting connecting frame. The lower end of the rotating columns is connected to a suspension part that can be hooked onto the container lifting hole. A connecting arm is connected to the rotating column, and a connecting rod that is rotatably connected to the telescopic end of the bidirectional hydraulic cylinder is rotatably connected to the connecting arm. The container lifting hole is rectangular, and the suspension part is a cuboid structure adapted to the container lifting hole.

[0008] A further improvement of this utility model is that the bottom of the suspension part has rounded corners on all four sides.

[0009] A further improvement of this utility model is that a boss is connected to the upper part of the rotating column, and a connecting arm is connected to the side wall of the boss; a support platform is installed on the hoisting connecting frame, which is fitted on the outside of the rotating column and can support the boss.

[0010] A further improvement of this utility model is that the support platform is a bearing.

[0011] A further improvement of this utility model is that a limiting block is connected to the boss, and a positioning hole is provided on the limiting block; a safety pin that can be inserted into the positioning hole is installed on the hoisting connecting frame.

[0012] A further improvement of this utility model is that a stop block capable of limiting the rotation of the limit block is also positioned and installed on the hoisting connecting frame.

[0013] A further improvement of this utility model is that the bottom of the rotating column is connected to the suspension part by a cylindrical connecting column, and the lower part of the connecting column is located inside the edge of the upper surface of the suspension part.

[0014] A further improvement of this utility model is that the container spreader is provided with spreader lugs, and an anti-detachment rod that can be connected to the spreader lugs is installed on the lifting connection frame.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0016] This non-standard lifting device is used in pairs. Two corresponding hooks on the left and right sides are connected to two connecting frame lifting holes on one non-standard lifting device. By manipulating the container front-end crane, the four suspension parts are inserted into the four lifting holes at the four corners of the container's upper side. Controlling the bidirectional hydraulic cylinders causes the connecting arm, rotating column, and suspension parts to rotate 90 degrees via the connecting rod, aligning the length of the suspension parts perpendicular to the length of the container lifting holes, thus achieving container lifting. By selectively adding non-standard lifting devices with suspension parts at different distances to the container front-end crane, convenient and flexible lifting of non-standard containers can be achieved. Compared to newly developed non-standard container spreaders, the cost is significantly reduced, the overall structure is simple, easy to use, and highly practical. Attached Figure Description

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] like Figure 8 The diagram shows a front-end lifting structure for a container, with four lifting hooks 11 positioned at the four corners of the container spreader 1.

[0029] like Figure 1-8 As shown, this utility model discloses a non-standard lifting device based on a container front-end crane, including a lifting connecting frame 2. A bidirectional hydraulic cylinder 3 is positioned and installed in the middle of the lifting connecting frame 2 in a left-right direction. The upper part of both ends of the lifting connecting frame 2 is provided with connecting frame lifting holes 4 that can be hung with the lifting hook 11 of the container spreader 1. Rotating columns 5 are vertically rotatably installed at both ends of the lifting connecting frame 2. The lower end of the rotating column 5 is connected to a suspension part 51 that can be hung on the container lifting hole 71 of the container 7. A connecting arm 52 is connected to the rotating column 5. A connecting rod 8 that is rotatably connected to the telescopic end of the bidirectional hydraulic cylinder 3 is rotatably connected to the connecting arm 52. The container lifting hole 71 is rectangular, and the suspension part 51 is a cuboid structure adapted to the container lifting hole 71.

[0030] This non-standard lifting device is used in pairs. Two corresponding lifting hooks 11 on the left and right sides are respectively attached to two connecting frame lifting holes 4 on one non-standard lifting device. By manipulating the container front-end crane, the four suspension parts 51 are inserted into the four container lifting holes 71 at the four corners of the upper side of the container 7. Controlling the bidirectional hydraulic cylinder 3 causes the connecting arm 52, rotating column 5, and suspension parts 51 to rotate 90 degrees via the connecting rod 8, making the length direction of the suspension parts 51 perpendicular to the length direction of the container lifting holes 71, thus achieving the lifting of the container 7. When unloading the container 7, controlling the bidirectional hydraulic cylinder 3 to reverse the action causes the suspension parts 51 to rotate 90 degrees in the opposite direction, disengaging the suspension parts 51 from the container lifting holes 71. By selectively adding non-standard lifting devices with suspension parts 51 at different distances to the container front-end crane, convenient and flexible lifting of non-standard containers can be achieved. Compared with newly developed non-standard container spreaders, the cost is significantly reduced, the overall structure is simple, easy to use, and highly practical.

[0031] The principle of attaching the spreader hook 11 to the connecting frame lifting hole 4 is the same as the principle of attaching the suspension part 51 to the container lifting hole 71. The lower end of the spreader hook 11 has a cuboid structure that fits the connecting frame lifting hole 4 (rectangular).

[0032] like Figure 2 As shown, the container spreader 1 is equipped with spreader lugs 12, and the lifting connecting frame 2 is connected to an anti-detachment rod 13 that can be connected to the spreader lugs 12. This improves the safety of use and effectively prevents accidental detachment and falling.

[0033] The bottom of the rotating column 5 is connected to the suspension part 51 via a cylindrical connecting column 57, and the lower part of the connecting column 57 is located within the edge of the upper surface of the suspension part 51. The size of the connecting column 57 is smaller than that of the suspension part 51, so that the rotating column 5 is not interfered with during rotation, thus achieving smooth rotation.

[0034] The bottom of the suspension part 51 has rounded corners on all four sides, which serves as a guide for insertion into the container lifting hole 71.

[0035] like Figure 3-5 As shown, a boss 55 is connected to the upper part of the rotating column 5, and a connecting arm 52 is connected to the side wall of the boss 55; a support platform 56 is installed on the lifting connecting frame 2, which is fitted onto the outside of the rotating column 5 and can support the boss 55. This effectively ensures the reliable lifting and load-bearing capacity of the rotating column 5 for the container 7, and also ensures the free rotation of the rotating column 5.

[0036] Furthermore, the support platform 56 is a bearing. This ensures the accuracy, reliability, and labor-saving operation of the rotating column 5.

[0037] Among them, such as Figure 3As shown, a limiting block 53 is also connected to the boss 55, and a positioning hole 54 is provided on the limiting block 53; a safety pin 6 is installed on the lifting connecting frame 2, which can be positioned and inserted into the positioning hole 54. When the suspension part 51 is attached to the container lifting hole 71, the safety pin 6 is inserted to position and insert the safety pin 6 into the positioning hole 54, which effectively prevents the suspension part 51 from rotating due to misoperation, avoids the container from falling, and has good safety.

[0038] Furthermore, the lifting connection frame 2 is also equipped with stop blocks 58 that can limit the rotation of the limit block 53. Each limit block 53 corresponds to two stop blocks 58, which restricts the limit block 53 from rotating within 90 degrees, thereby improving the accuracy of the insertion of the suspension part 51 into the container lifting hole 71 and the reliability of the lifting of the container 7.

[0039] This non-standard lifting device, based on a container front-end crane, is used in pairs. Two corresponding lifting hooks 11 on the left and right sides are respectively connected to two connecting frame lifting holes 4 on a non-standard lifting device. By manipulating the container front-end crane, the four suspension parts 51 are inserted into the four container lifting holes 71 at the four corners of the upper side of the container 7. Controlling the bidirectional hydraulic cylinder 3 actuates the connecting rod 8, causing the connecting arm 52, rotating column 5, and suspension parts 51 to rotate 90 degrees, making the length direction of the suspension parts 51 perpendicular to the length direction of the container lifting holes 71, thus achieving the lifting of the container 7. By selectively adding non-standard lifting devices with suspension parts 51 at different distances to the container front-end crane, convenient and flexible lifting of non-standard containers can be achieved. Compared with newly developed non-standard container spreaders, the cost is significantly reduced, the overall structure is simple, easy to use, and highly practical.
