Description

Technical Field

[0001] This utility model relates to the field of container loading and unloading technology, specifically a portable tool for container loading and unloading. Background Technology

[0002] Container shipping is widely used in air, sea, and land transportation (including road and rail) for various goods due to its inherent advantages. To accommodate the loading and unloading needs after container arrival, air transport often has large-scale loading and unloading equipment at airports, seaports at seaports, and land transport at stations. Therefore, the advantages of port-to-port and station-to-station container transport are very obvious. However, with the further development of the logistics industry, the demand for loading and unloading operations after container arrival and for door-to-door container transport is increasing. How to better meet these demands has become one of the key aspects of developing container shipping.

[0003] Chinese Patent CN105270884B discloses a portable tool for container loading and unloading, including a support base and a column connected to the upper end of the support base. A connecting sleeve is fitted onto the column. A rack is provided on the side of the column. A gear drive box that cooperates with the rack is provided on the connecting sleeve, forming a lifting device in which the gear drive box drives the connecting sleeve to move vertically up and down along the column. A container upper clamp is horizontally connected to the top of the connecting sleeve. A container lower connecting assembly is also provided at the lower end of the connecting sleeve. The container lower connecting assembly includes a container lower connector, a horizontal support plate, and a diagonal tie rod. The two ends of the horizontal support plate are rotatably connected to the connecting sleeve and the container lower connector, respectively. The diagonal tie rod is inclined above the container lower connector and the horizontal support plate, and the two ends of the diagonal tie rod are rotatably connected to the connecting sleeve and the container lower connector, respectively. The container lower connector, the horizontal support plate, and the diagonal tie rod together form a triangular structure. The container upper clamp and the container lower connecting assembly are both located on the same side of the lifting device.

[0004] The existing technical solution described above has the following drawbacks: Since the tool comprises multiple components such as a support base, column, connecting sleeve, gear drive box, container upper clamp, and container lower connecting assembly, and these components are mostly made of metal, the overall weight may be significant. Furthermore, the technical solution does not mention any moving device, such as wheels, tracks, or sliding mechanisms, making it difficult to move the tool on the ground. Without a moving device, the tool may need to be lifted or dragged as a whole, which is not only laborious but may also damage the tool itself.

[0005] To address this issue, we propose a portable tool for container loading and unloading. Utility Model Content

[0006] The purpose of this invention is to provide a portable tool for loading and unloading containers, so as to solve the problem of inconvenience in movement mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a portable tool for loading and unloading containers, comprising a support base and a loading and unloading mechanism disposed on the upper surface of the support base, wherein the loading and unloading mechanism comprises a moving unit and a lifting unit;

[0008] The moving unit includes casters, hydraulic cylinders, and support blocks. The casters are arranged in pairs on the front and rear sides of the lower surface of the support base. The hydraulic cylinders are fixedly connected to the left and right sides of the lower surface of the support base. The upper surface of the support block is fixedly connected to the output end of the hydraulic cylinders.

[0009] Preferably, the lifting unit includes a telescopic column, a cylinder, a housing, a transverse connecting seat, a stop block, a lead screw nut, a threaded rod, and a motor. The bottom of the telescopic column is fixedly connected to the middle of the upper surface of the support base. The bottom of the cylinder is connected to the inside of the telescopic column. The bottom of the housing is fixedly connected to the top of the telescopic column. The motor is fixedly connected to the inside of the housing. The left side of the transverse connecting seat is fixedly connected to the right side of the housing. A groove is provided inside the transverse connecting seat. Both ends of the threaded rod are connected to the transverse connecting seat. The lead screw nut is threadedly connected to the threaded rod. The bottom surface of the stop block is fixedly connected to the upper surface of the lead screw nut. The motor drives the threaded rod to rotate, thereby causing the lead screw nut to move along the threaded rod, which can better bring the lifting frame closer to the container. The cylinder and telescopic column make the lifting process more reliable.

[0010] Preferably, the bottom surfaces of the abutting block abut against the upper surface of the transverse connecting seat on both sides to prevent the lead screw nut from shaking or shifting during movement, thereby increasing stability.

[0011] Preferably, a connecting rod is fixedly connected to the bottom of the lead screw nut, a lifting block is fixedly connected to the bottom end of the connecting rod, and a lifting frame is fixedly connected to the right side of the lifting block, converting the output of the lifting unit into a direct lifting force on the container. Through the combination of the connecting rod, lifting block, and lifting frame, a stable grip and lifting of the container can be achieved, providing strong support for loading and unloading operations.

[0012] Preferably, the upper surface of the lifting frame is provided with anti-slip texture. The anti-slip texture can increase the friction between the lifting frame and the bottom of the container, preventing the container from slipping or sliding during the lifting process, thereby improving the safety and reliability of loading and unloading operations.

[0013] Preferably, there are four sets of lifting units, each with the same structure. The bottom of the container abuts against the upper surface of the lifting frame on all four sides. The simultaneous use of the four sets of lifting units ensures that the container receives uniform and stable support during loading and unloading. This design not only improves loading and unloading efficiency but also reduces the risk of damage to the container during the process.

[0014] Preferably, the bottom surface of the support block is provided with multiple protrusions. These protrusions increase the contact area with the ground, allowing the support block to be firmly fixed to the ground when needed, thereby further increasing the stability of the entire loading and unloading tool. This is especially important for loading and unloading operations on uneven or soft ground, ensuring the safety and smooth progress of the loading and unloading process.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This portable tool for container loading and unloading features casters in its mobile unit, allowing for easy movement between different locations and improving its flexibility. Simultaneously, the combination of hydraulic cylinders and support blocks ensures the entire mechanism is securely fixed to the ground.

[0017] 2. This portable tool for container loading and unloading uses a motor-driven threaded rod to move, allowing the lifting frame to better fit against the side of the container. The anti-slip texture on the upper surface of the lifting frame increases the friction between it and the bottom of the container, effectively preventing the container from slipping or sliding during the lifting process, thereby significantly improving the safety and reliability of loading and unloading operations.

Detailed Implementation

[0023] Please see Figures 1-4This utility model provides a technical solution: Example

[0024] A portable tool for container loading and unloading includes a support base 1 and a loading / unloading mechanism disposed on the upper surface of the support base 1. The support base 1 serves as the basic support structure for the entire tool, providing a stable platform for fixing and operating other components. The loading / unloading mechanism includes a moving unit; the moving unit includes casters 3, hydraulic cylinders 401, and support blocks 402. The casters 3 are arranged in pairs on the front and rear sides of the lower surface of the support base 1, allowing the tool to move easily in different directions, increasing operational flexibility and convenience. The hydraulic cylinders 401 are fixedly connected to the left and right sides of the lower surface of the support base 1. The upper surface of the support block 402 is fixedly connected to the output end of the hydraulic cylinder 401. The bottom surface of the support block 402 is provided with protrusions, which, by providing vertical lifting force, can adjust the height of the support block 402, allowing the tool to adapt to different ground conditions or operational needs. Connected to the output end of the hydraulic cylinder 401, it increases the contact area between the tool and the ground, improving stability. The protrusion design enhances the anti-slip effect and prevents the tool from slipping during use. Example

[0025] Based on Embodiment 1, the loading and unloading mechanism further includes a moving unit. The lifting unit includes a telescopic column 2, a cylinder 7, a housing 501, a transverse connecting seat 502, an abutment block 503, a lead screw nut 504, a threaded rod 505, and a motor 506. The bottom of the telescopic column 2 is fixedly connected to the middle of the upper surface of the support base 1, allowing the loading and unloading mechanism to be adjusted vertically, increasing operational flexibility and applicability. The bottom of the cylinder 7 is connected inside the telescopic column 2, providing additional lifting force or fine-tuning function, which helps to more accurately control the height of the loading and unloading mechanism. The bottom of the housing 501 is fixedly connected to the top of the telescopic column 2, serving as a protective shell for the motor 506 and other related components, preventing damage to the internal mechanical parts from external factors such as dust and moisture. The motor 506 is fixedly connected inside the housing 501, and the left side of the transverse connecting seat 502 is fixedly connected to the right side of the housing 501, providing stable support for the threaded rod 505 and the lead screw nut 504, enabling them to rotate smoothly and drive the connecting rod 6 and the lifting block 601 to move horizontally. The transverse connecting seat 502 has a groove inside. The threaded rod 505 is connected to the transverse connecting seat 502 at both ends. A lead screw nut 504 is threadedly connected to the lead screw nut 504. A connecting rod 6 is fixedly connected to the bottom of the lead screw nut 504. A lifting block 601 is fixedly connected to the bottom of the connecting rod 6. A lifting frame 602 is fixedly connected to the right side of the lifting block 601. The upper surface of the lifting frame 602 has anti-slip textures 603, which are directly used for contacting and lifting the container. The anti-slip textures 603 on the lifting block 601 enhance the friction between it and the container, preventing slippage during lifting.

[0026] The bottom surface of the abutment block 503 is fixedly connected to the upper surface of the lead screw nut 504. The two sides of the bottom surface of the abutment block 503 abut against the upper surface of the transverse connecting seat 502, providing protection for the lead screw nut 504.

[0027] Working principle: Move the tool to the vicinity of the container, start the hydraulic cylinder 401, adjust the height of the support block 402 according to the ground conditions to ensure that the tool can be fixed on the ground, and then start the cylinder 7 to fine-tune the telescopic column 2 to ensure that the lifting frame 602 can be accurately aligned with the bottom of the container.

[0028] Then, start motor 506 to drive threaded rod 505 to rotate, which in turn moves screw nut 504 along threaded rod 505. As screw nut 504 moves, connecting rod 6, lifting block 601, and lifting frame 602 gradually approach the container. When lifting frame 602 contacts the container, start cylinder 7 to lift the container to the required height. While lifting the container, the tools and container can be moved to the designated position using casters 3. After reaching the designated position, start motor 501 in reverse, causing screw nut 504 to move in the opposite direction along threaded rod 505. As screw nut 504 moves, connecting rod 6, lifting block 601, and lifting frame 602 gradually move away from the container until the container is lowered. After completing the loading and unloading task, turn off all power sources.
