Abstract

The present invention relates to a platform-type container mountable on a PLS truck and a fixing structure for a modular storage rack installed inside the same. In order to solve the problem of a storage rack shaking or detaching due to vibration or shock while driving, the present invention forms a plurality of pocket-shaped fixing grooves on the bottom of a container and configures the support legs of a modular storage rack to be inserted into the fixing grooves. In addition, the rack fixing pin penetrates the base frame of the container and then sequentially penetrates and connects the front and rear surfaces of the pocket-type fixing groove and the support legs of the modular storage rack, thereby providing a structure in which the modular storage rack is double-fixed. This effectively prevents the modular storage racks from shifting, enhancing safety and loading stability during the transportation of military supplies, while the double-door front of the container provides excellent accessibility, resulting in increased operational efficiency for logistics support.

Description

Platform-Type Container Equipped with Modular Storage Racks for PLS Trucks The present invention relates to a container structure suitable for the storage and transportation of military or field supplies, and in particular to a container equipped with a modular storage rack platform that is mounted on a Palletized Load System (PLS) truck to enable rapid loading and unloading of military supplies. The PLS truck is a specialized cargo transport system composed of a lift system (hook arm) and a detachable flat rack to load and unload palletized cargo, capable of performing the functions of both a truck and a trailer simultaneously. These PLS trucks can transport various cargo, such as military ammunition, food, and equipment, loaded on flat racks, and the flat racks can be detached on-site to be used as a work platform for field operations. In addition, when a PLS truck is equipped with a CHU (Container Handling Unit), standard-sized containers can be directly loaded and unloaded, enabling the mobile installation of various field facilities such as barracks, kitchens, field hospitals, command posts, and restrooms. Meanwhile, regarding prior art literature related to such PLS trucks, the applicant of the present invention's previously registered invention, "Patent Registration No. 2529417, Title/ National Mobility Platform PLS Truck System," is proposed. However, the most fundamental problem with the containers loaded on conventional PLS trucks including the prior art mentioned above is the detachment and damage of modular storage racks due to vibration and shock while driving. When driving on rough or unpaved roads, shelf-type and drawer-type storage racks receive severe vibrations, causing the equipment to shake, detach, or overturn, resulting in cargo falling and frequent safety accidents such as worker injuries. Furthermore, due to the inefficiency of sorting and securing caused by the simplicity of the internal loading structure, the interior of the container was a single-layer flat structure or a form of simple supports, making it difficult to efficiently sort and secure goods by size and weight, and consequently, space utilization was very low. In addition, there are frequent work safety accidents and door damage accidents where workers are struck by the door and it closes due to wind or vibration while the door is open for loading and unloading military supplies. In addition, due to issues with the mixing of items inside and unstable opening and closing of drawer-type fixed racks, drawers would shake and open while in motion, or items would become mixed due to the lack of internal compartmentalization, resulting in loss of parts or collision damage. These issues degraded the transport stability, operational efficiency, and safety of PLS-based logistics support systems, placing significant limitations on field mobility and rapid deployment. Therefore, a container body based on a modular storage rack is required that can be mounted on a PLS truck to enable rapid loading and unloading, while ensuring both driving stability and on-site operational capability.
