KR-20260066667-A - LOGISTICS SYSTEM OR LOGISTICS DEVICE FOR NERROW SPACES AND CONFINE SPACES.

Abstract

The present invention is intended to efficiently transport excavated spoil, rocks, minerals, etc., from narrow spaces or tunnels using a large-capacity, high-load trailer. The invention provides a method to maximize the transport of goods, bulk, excavated spoil, rocks, minerals, etc., from narrow and limited spaces or tunnels by using a towing tractor truck and a loading trailer that can be coupled and separated from the front and rear of the tractor truck to operate, thereby loading the maximum capacity in the shortest possible time.

Claims (4)

1. In this invention, the structure of a currently widely used commercial logistics trailer is modified to add a screw jack used for parking and stopping to the wheel position and mount it on the trailer frame to enable self-standing and parking, and a structure is provided in which towing pins that engage with the turntable of a tractor truck when towing the trailer are mounted on the front and rear of the trailer. Wheel axles and wheels arranged spaced apart from each other in the central part of the above trailer; Two screw jacks, positioned at the front and rear respectively on the trailer frame of the wheel axles and wheels in the central part of the above trailer; A trailer equipped with towing pins at the front and rear that are coupled to the turntable of the above-mentioned tractor truck; A tractor truck and trailer structure configured to include a towing pin that connects the trailer to a turn table mounted on the tractor truck at the front and rear, and is characterized by enabling the tractor truck to connect and disconnect the towing pin according to the towing direction.
2. In claim 1, the trailer is, A trailer structure in which a flat plate is installed on the upper part of the above trailer, or a bulk cargo box, container, etc. are added to load, allowing the container to be varied according to the intended use, purpose, and cargo, and which is based on a single axle and allows for the addition or accommodation of axles depending on the load and use; Composed including, for loading or unloading goods onto or from a trailer in a confined space, a tractor truck and a trailer are coupled to enter the confined space, and after separating the trailer towing pin and the tractor truck's turntable; After the tractor truck turns and moves forward to exit in the opposite direction from the entry point in a narrow space; After the tractor truck reverses in a confined space and engages the trailer towing pin with the tractor truck's turntable; A tractor truck and trailer logistics system and logistics device characterized by the tractor truck operating a trailer.
3. In paragraphs 1 and 2, the above trailer is, After installing a bulk cargo box on the top of the above trailer; Actuators are installed on the front and rear of the bulk cargo box and on the trailer, and on the trailer and the bulk cargo box; A trailer structure characterized by opening and closing the side of the bulk cargo box and raising, lowering, and rotating the bulk cargo box to unload bulk cargo to the side.
4. In paragraphs 1 and 2, the above tractor truck, trailer, cargo box, and loading equipment are, After installing actuators on the above trailer and bulk cargo box; This includes not installing a 'turning point (space)' installed when applying tractor trucks, trailers, and bulk cargo boxes to confined spaces where cargo loading equipment is used in a narrow area where turning and rotating are impossible; A logistics system and a logistics device characterized by enabling existing cargo loading equipment to be loaded onto a trailer without a 'turning point (space)'.

Description

Logistics system or logistics device for narrow spaces and confined spaces. The present invention relates to a logistics system and a logistics device for loading, unloading, and transporting goods. Developed in the 1930s, trailers and tractor trucks, along with containers, are the most common and efficient systems in land and sea logistics systems and logistics equipment worldwide. In this application, regarding the loading, unloading, and transportation of logistics systems and logistics devices, there are many areas where it is impossible to secure turning points or return lanes for vehicles in narrow spaces, and to resolve this, cases of occupying two or three lanes of main roads frequently occur. In this application, the most problematic aspect of using trailers and tractor trucks is that loading, unloading, and driving in confined spaces is very difficult, cumbersome, time-consuming, and costly, and in most cases impossible. In using trailers and tractor trucks in confined spaces, we intend to enable loading, unloading, and transportation in confined spaces by modifying the structure of existing trailers and applying tractor trucks. FIG. 1 is a plan and side view of a typical trailer. FIG. 2 is a plan and side view of the trailer of the present application. Figure 3 shows a typical combination of a trailer and a tractor truck. FIG. 4 is a combined view of the trailer and tractor truck of the present application. FIG. 5 is a plan view (middle) and side view (bottom) of a trailer with added wheel axles and tires (top) for heavy loading according to the present application, and a combination of the trailer and a tractor truck. FIG. 6 is a trailer with a side-dumping cargo box installed on the trailer of FIG. 5 (top), a plan view (middle), and a side view (bottom) of the combined trailer and tractor truck. Fig. 7 is the front, side, and rear views of a tractor truck. FIG. 8 is a cross-sectional view showing side dumping on a trailer equipped with a cargo box for side dumping, with a hydraulic cylinder for dumping and a hydraulic cylinder for opening and closing the side of the cargo box installed. FIG. 9 illustrates the process of entering a narrow area by combining the towing pin of the trailer of the present application and the turn table of the tractor truck, and after the towing pin of the trailer and the turn table of the tractor truck are separated, the tractor truck alone rotates to exit to the opposite side of the entrance, and then returns to the tractor truck of the present application by combining the rear towing pin and the turn table of the tractor truck. FIG. 10 illustrates the process of installing a side dumping cargo box on the trailer of the present application, entering a narrow area, and loading the loader bucket by moving horizontally, rising, and rotating to the cargo box. FIG. 11 illustrates the process of installing a side dumping cargo box on the trailer of the present application, entering a narrow area, and having the bucket of an excavator accumulate, rise, and rotate to load into the cargo box. FIG. 12 illustrates that a loading loader cannot rotate on its own in a narrow area (e.g., a tunnel). Fig. 13 a. Illustrates that in the absence of a turning station, a loading loader moves out of a narrow area (e.g., a tunnel) and loads spoil in a vast area outside the tunnel. Fig. 13 b. Illustrates that, where there is a turning station, a loading loader can load (carry) spoil inside a narrow area (e.g., a tunnel). Fig. 14 a. Illustrates that a commercial dump truck cannot turn inside a narrow area (e.g., a tunnel). Fig. 14 b. Illustrates that a commercial dump truck cannot turn when a small turning point is installed inside a narrow area (e.g., a tunnel). Fig. 14 c. Illustrates that a commercial dump truck can turn when a medium-to-large turning point is installed inside a narrow area (e.g., a tunnel). Fig. 15 illustrates the loading and transport of spoil by installing a medium-to-large turning point inside a narrow area (e.g., a tunnel) using a loading loader and a dump truck.
