Technical Field
[0001] This utility model relates to the field of transportation equipment technology, specifically to a container body that prevents cargo from tilting and getting stuck. Background Technology
[0002] Box trucks generally have large cargo compartments, so various issues related to loading and unloading need to be considered, especially for large and heavy-duty compartments and the loading and unloading of large and heavy cargo. To significantly improve the efficiency and safety of cargo loading and unloading, reduce labor costs, increase automation efficiency, and improve space utilization, many box trucks are equipped with conveyor systems. Our company has designed several technical solutions for these compartments, such as application number 2024209399707, entitled "A Demountable Box Scheme"; application number 2024226315651, entitled "A Box in a Demountable Box Moving Device"; and application number 2024207066865, entitled "A Base Frame for a Positioning and Correction Buffer Device for Demountable Vehicles that Cooperates with a Box in a Demountable Box Moving Device." Although many existing box trucks have conveyor systems, their designed conveyor schemes may not be suitable for our company's designed compartments. Therefore, our company has designed a simple and effective conveyor system for all our existing compartments. Utility Model Content

The bottom surface of the reinforcing brace 11 is fixedly connected to the conveyor plate 8. On the opposite side of the upright frame 9, a roller 10 is fixedly installed that can roll on the support rod 4 and rolls longitudinally; the reinforcing brace 11 improves the connection strength between the upright frame 9 and the conveyor plate 8 and improves stability. The roller 10 supports the upright frame 9 from the other side and can assist the upright frame 9 in moving, reducing the friction between the upright frame 9 and the conveyor plate 8 and the top plate after installation, making it easier to move.
[0027] By installing a conveyor plate 8 inside the compartment, fixing a support frame 9 on the conveyor plate 8, and installing pulleys 14 that cooperate with the support frame between two columns 1, the support frame 9 can maintain the stability of the support frame and the goods on it and move easily when it moves with the conveyor plate 8. The overall structure is simple and the conveying effect is good. The conveyor plate only covers half of the entire chain along the chain running direction, which greatly reduces the cost. The rollers cooperate with the reinforcing supports to keep the support frame stable and easy to move.
[0028] The pulley structure includes pulleys 14 horizontally positioned between the left and right columns 1. Horizontally placed, these pulleys can roll relative to the sidewall of the passageway 16, facilitating the movement of the upright 9 along the conveyor plate 8. Several pulleys 14 are arranged at longitudinal intervals within the same horizontal plane, forming a group of pulley structures. At least one group of pulley structures is present on the same side plate 2. When there are two or more groups of pulley structures, these groups are arranged at vertical intervals along the side plate 2. Generally, pulley structures are installed between the left and right columns 1 near the front side plate 2 and between the left and right columns 1 near the rear side plate 2. Each pulley structure also includes two fixing strips 12 installed at vertical intervals along the side plate 2. The fixing strips 12 are arranged longitudinally, and a pulley 14 is positioned between the two fixing strips 12.

[0029] The upright 9 includes two side rods 15 respectively located near the front and rear ends of the body, and a main body located between the two side rods 15; at least one side rod 15 has a longitudinally provided through groove 16 adapted to the pulley 14, and the pulley structure passes through the through groove 16 longitudinally; the width of the through groove 16 is adapted to the diameter of the pulley; when the upright 9 moves, the pulley 14 rolls on its inner wall when passing through the through groove 16; the pulley structure is only located between the side rods 15 with the through groove 16 and the adjacent uprights 1.
[0030] The power module includes a power unit base fixedly mounted on a bracket, on which a power unit is fixedly mounted. The output end of the power unit is connected to the transmission module 7 via a chain module. The power unit can be a motor, etc. The transmission module 7 includes a sprocket connected to the chain module, a transmission shaft connected to the sprocket and arranged laterally, and a chain connected to the sprocket and arranged longitudinally. Several sprockets are arranged on the transmission shaft, and both ends of the transmission shaft are fixed to the power unit base. A transmission plate 8 is fixedly mounted on the upper part of the chain. The chain module includes an output shaft connected to the output end of the power unit, and an output gear is fixedly mounted on the output shaft. The output gear is connected to the sprocket via a transmission chain. The length of the transmission plate 8 is half the length of the chain.
[0031] A baffle 5 is installed on the outside of the bracket to separate the inside and outside of the bracket, which not only achieves an aesthetic effect but also protects the internal structure.
[0032] During operation, the power unit is activated, which drives the output shaft, which in turn drives the output gear, which drives the chain, which in turn drives the sprocket, which in turn drives the drive shaft, which drives other sprockets, which in turn drive the chain, which in turn drives the sprocket at the opposite end of the chain. This causes the conveyor plate 8 to start moving, which in turn moves the upright frame 9. The rollers 10 roll on the support rod 4, while the pulleys 14 pass through the passage groove 16 one by one and roll due to contact with the passage groove, thus conveying the goods out.
