Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more specifically to a modular lifting device for quickly separating and connecting containers to a vehicle chassis. Background Technology

[0002] Demountable wagons or containers offer advantages such as improved transportation efficiency, enhanced transportation flexibility, and reduced costs. Once transported to their destination, the entire wagon needs to be unloaded. Because wagons vary in size and are often quite large and heavy, specialized equipment for loading and unloading them is required. Existing loading and unloading equipment is inconvenient, generally relying on cranes for movement, which can lead to misalignment during loading and unloading, posing significant safety hazards and incurring high costs. For example, the technical solution in Chinese utility model patent CN202120970522.X has relatively fixed functions and a low degree of systematization. Other methods involve using cranes with specialized lifting devices to load, unload, and transfer the container, or installing rollers at the bottom of the container for transfer. Another example is Chinese invention patent CN202110638583.0, entitled "A Container Quick Loading and Unloading Mechanism." While this solution can disassemble the container, it cannot correct misalignment during installation onto the chassis, posing safety hazards, requiring highly skilled drivers, and making it impossible to ensure that the chassis frame fixing pins align perfectly with the container corner fixing holes, sometimes even preventing installation altogether. Therefore, a convenient, safe, and easily correctable container loading and unloading device is needed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a prefabricated lifting device that enables the rapid separation and assembly of containers and automobile chassis. It is positioned at the four corners of the vehicle body by setting at least four lifting and self-moving correction lifting structures. The correction lifting structures are equipped with guide slopes, which are reusable, easy to disassemble, simple to operate, and highly safe.

This invention not only inherits the functional concept of using guide ramps for correction and alignment, but more importantly, through modular and detachable design, it achieves a high degree of functional integration and a revolutionary change in the operating mode. Each correction and lifting structure is an intelligent unit integrating guidance and correction, hydraulic / electric lifting, powered / unpowered travel, and anti-tipping protection. Multiple units work collaboratively through a telescopic linkage mechanism to form a complete system capable of autonomously completing the entire process of container pickup, lifting, horizontal correction, longitudinal and lateral movement, and precise placement back onto the chassis.

Furthermore, the equipment is easy to maintain and schedule, resulting in low overall operating costs. Attached Figure Description

[0039] "Directly inside or inside a partition" means that the lifting column 102 is directly inside the inner wall of the outer cylinder 1. Another situation is that the lifting column 102 is inside the outer cylinder 1, and a sleeve is also installed on the outside of the lifting column 102. "Directly or indirectly" generally means that the two are connected by other components, or that there are other components connecting the two. "Or set" means to set or not set.

[0040] The transfer bracket 4 uses all or part of the technical solution of the application number 2025224029772, which we have designed and submitted, entitled "A Transfer Device in a Factory Area"; or it can use all or part of the technical solution of the application number CN202120970522.X, entitled "A Loading and Unloading Positioning Vehicle-Mounted Device".

[0041] "The bottom of the container's frame along a certain direction" refers to the frame that the container itself is attached to.

[0042] The two options for the first fixed frame and the three options for the second fixed frame can be combined and used according to the actual situation.

[0043] One of the working processes is as follows: The rollers 109 are used to move the alignment lifting and positioning structure to the carriage. Based on the carriage length, the four alignment lifting and positioning structures in the same group correspond to the four corners of the carriage. During this process, the telescopic frame extends, and the first connecting rod 202 and the second connecting rod 203 form several interconnected scissor bracing structures. This is a conventional structure. When extending or retracting, the second connecting rod 203 connected to the front rail 2 slides down, and the first connecting rod 202 connected to the rear rail 2 slides down. Then, the rollers 109 are retracted so that the roller assembly 101 touches the ground. Next, the second fixed cone 1010 and the first fixed cone 104 are raised so that they correspond to the holes at the bottom and top of the carriage. Then, the power unit is activated to move the alignment lifting and positioning structure towards the carriage until the second fixed cone 1010 is inserted into the bottom hole of the carriage. Then, the lifting column 102 is lowered so that the first fixed cone 104 is inserted into the top hole, completing the fixing. Then, the relevant components are activated to detach the carriage from the trailer chassis, and then the carriage is moved to another location.
