Description

Technical Field

[0001] This invention relates to the field of semi-trailer technology, specifically to a detachable semi-trailer frame for container transportation. Background Technology

[0002] In the field of modern logistics and transportation, containers have become one of the core carriers of cargo transportation due to their advantages of standardization and large capacity. As the main means of transporting containers, the performance of semi-trailers directly affects transportation efficiency, safety and flexibility of use.

[0003] Traditional semi-trailers have poor adaptability to containers. The end seats and strut positions of existing semi-trailers are mostly fixed, only compatible with containers of specific lengths. However, in actual logistics transportation, containers come in various lengths. Transporting containers of different lengths requires changing to corresponding semi-trailers, forcing transportation companies to maintain multiple semi-trailers of different models to meet demand. This not only increases equipment purchase costs but also wastes idle equipment. Furthermore, while some semi-trailers have attempted to adapt to different containers by adding adjustable struts, the adjustment structure is rudimentary, often using manual plug-and-play fixing. The adjustment process is cumbersome and has low positioning accuracy. Even after adjustment, the connection stability between the struts and the semi-trailer body is insufficient, still failing to guarantee the stability of the container during transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable semi-trailer frame for container transportation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable semi-trailer frame for container transportation, comprising two longitudinal beam units, a crossbeam assembly installed between the two longitudinal beam units, fixed support components for mounting containers installed on opposite sides of the two longitudinal beam units, movable support components suitable for different containers installed on opposite sides of the two longitudinal beam units, connecting components for adjusting the movable support components installed inside the two longitudinal beam units, and movable grooves provided on opposite sides of the two longitudinal beam units.

[0006] Preferably, the crossbeam assembly includes a crossbeam body, a crossbeam pad is fixedly installed on the top of the crossbeam body, crossbeam assembly blocks are fixedly installed at both ends of the crossbeam body, and a side limiting plate is fixedly installed on one side of each crossbeam assembly block.

[0007] Preferably, each of the crossbeam assembly blocks has a second crossbeam assembly threaded hole inside. Each of the two longitudinal beams has a crossbeam assembly seat fixedly installed on opposite sides. The top and bottom of the crossbeam assembly seat have a first crossbeam assembly threaded hole. The crossbeam assembly block is snapped into the inside of the crossbeam assembly seat. The specifications of the second crossbeam assembly threaded hole are the same as those of the first crossbeam assembly threaded hole. The internal threads of the first and second crossbeam assembly threaded holes are connected by assembly bolts.

[0008] Preferably, each of the crossbeam bodies has a wire-threading block fixedly installed at its bottom, and each wire-threading block has a wire-threading groove inside.

[0009] Preferably, each of the fixed support components includes a first fixed support assembly plate and a second fixed support assembly plate. One side of the first fixed support assembly plate is fixedly connected to one side of the longitudinal beam. A fixed support is fixedly installed on one side of the second fixed support assembly plate. A fixed support block is fixedly installed at the end of the fixed support away from the second fixed support assembly plate. A movable end seat is fixedly installed on the top of the fixed support block. Fixed support assembly threaded holes are provided inside both the second fixed support assembly plate and the first fixed support assembly plate.

[0010] Preferably, the movable support assembly includes a second movable support assembly plate and a first movable support assembly plate. One side of the second movable support assembly plate is fixedly connected to the connecting assembly. A movable support bar is fixedly installed on one side of the first movable support assembly plate. A movable support block is fixedly installed at the end of the movable support bar away from the first movable support assembly plate. A fixed end seat and a side mounting seat are fixedly installed on the top of the movable support block. Movable support bar assembly threaded holes are opened inside both the first and second movable support assembly plates.

[0011] Preferably, both the movable end seat and the fixed end seat have end mounting threaded holes inside, and the fixed end seat, the movable end seat, and the side mounting seat all have side mounting threaded holes inside.

[0012] Preferably, the connecting component includes a connecting block, a connecting rod is fixedly installed between two adjacent connecting blocks, a movable slider is fixedly installed on one side of each connecting block, and one side of the movable support assembly plate is fixedly connected to one side of the movable slider.

[0013] Preferably, reinforcing strips are fixedly installed at the top and bottom of both the movable support and the fixed support.

[0014] Preferably, the dimensions of the inner contour of the movable slide groove are adapted to the dimensions of the outer contour of the movable slider, and the movable slider is slidably installed inside the movable slide groove. Reinforcing rings are fixedly installed inside the two longitudinal beams, and the connecting block is slidably installed inside the reinforcing rings.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: The movable slider can slide inside the movable groove, thereby adjusting the position of multiple movable support assembly plates and thus the position of the fixed end seat and side mounting seat. This allows the semi-trailer body to adapt to containers of different lengths, significantly improving the versatility and usability of the device and expanding its application range. Furthermore, by fixing the container to the top of the semi-trailer body, the installation method is not only convenient and greatly reduces the labor intensity of workers, but also allows for easy disassembly and replacement of the container by simply unscrewing the bolts, greatly improving operational efficiency.

[0016] The longitudinal beams are internally reinforced with reinforcing rings made of high-strength materials. These rings effectively enhance the rigidity of the longitudinal beams, thereby improving the overall rigidity and load-bearing capacity of the semi-trailer. When the semi-trailer bears the weight of a container, the reinforcing rings can distribute some of the stress, reducing the deformation of the longitudinal beams and ensuring the structural stability of the semi-trailer during long-term use. Simultaneously, the connecting blocks inside the longitudinal beams can slide freely within the reinforcing rings. When a container is placed on the semi-trailer, its weight is rationally distributed, resulting in more even stress distribution across the semi-trailer and further improving its stability and service life, thus ensuring safety throughout the transportation and use process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-7This invention provides a technical solution: a detachable semi-trailer frame for container transportation, comprising two longitudinal beams 1, with a crossbeam assembly installed between the two longitudinal beams 1. The crossbeam assembly includes a crossbeam body 21, a crossbeam pad 6 fixedly installed on the top of the crossbeam body 21, crossbeam assembly blocks 31 fixedly installed at both ends of the crossbeam body 21, a side limiting plate 30 fixedly installed on one side of each crossbeam assembly block 31, and crossbeam assembly threaded holes 32 formed inside each crossbeam assembly block 31. Crossbeam assembly seats 25 are fixedly installed on opposite sides of the two longitudinal beams 1, with crossbeam assembly threaded holes 26 formed at the top and bottom of the inner cavity of the crossbeam assembly seat 25. The crossbeam assembly blocks 31 are snapped into the inside of the crossbeam assembly seat 25, with the crossbeam assembly threaded holes... The specifications of the second 32 are the same as those of the first 26 of the crossbeam assembly threaded hole. Assembly bolts 20 are connected internally to the first 26 and the second 32 of the crossbeam assembly threaded hole. Fixed support assemblies for container installation are installed on opposite sides of both longitudinal beams 1. Each fixed support assembly includes a first 23 and a second 13 of the fixed support assembly plate. One side of the first 23 is fixedly connected to one side of the longitudinal beam 1. A fixed support 10 is fixedly installed on one side of the second 13 of the fixed support assembly plate. A fixed support block 19 is fixed to the end of the fixed support 10 away from the second 13 of the fixed support assembly plate. A movable end seat 11 is fixedly installed on the top of the fixed support block 19. The second 13 and the first 23 of the fixed support assembly plate... Both longitudinal beams 1 and 24 have threaded holes 22 for fixing the support bars. The opposing sides of each longitudinal beam 1 are equipped with movable support assemblies suitable for different containers. The movable support assemblies include a second movable support bar assembly plate 14 and a first movable support bar assembly plate 7. One side of the second movable support bar assembly plate 14 is fixedly connected to a connecting assembly. A movable support bar 8 is fixedly installed on one side of the first movable support bar assembly plate 7. A movable support block 9 is fixedly installed at the end of the movable support bar 8 away from the first movable support bar assembly plate 7. A fixed end seat 3 and a side mounting seat 18 are fixedly installed on the top of the movable support block 9. Both the first movable support bar assembly plate 7 and the second movable support bar assembly plate 14 have threaded holes 24 for fixing the support bars. Both the movable end seat 11 and the fixed end seat 3 have threaded holes 4 for end mounting. The fixed end seat 3, the movable end seat 11, and the side mounting seat 18 all have side mounting threaded holes 5 inside. Both longitudinal beam bodies 1 have connecting components for adjusting the movable support assembly inside. The connecting components include connecting blocks 27, with connecting rods 28 fixedly installed between adjacent connecting blocks 27. A movable slider 29 is fixedly installed on one side of each connecting block 27. One side of the movable support assembly plate 14 is fixedly connected to one side of the movable slider 29. Movable grooves 15 are provided on opposite sides of both longitudinal beam bodies 1. The inner dimensions of the movable groove 15 are compatible with the outer dimensions of the movable slider 29, and the movable slider 29 is slidably installed inside the movable groove 15. Reinforcing rings 2 are fixedly installed inside both longitudinal beam bodies 1.The connecting block 27 is slidably mounted on the inner side of the reinforcing ring 2.

[0027] The working principle of the above technical solution is as follows: The longitudinal beam body 1 is welded from four steel plates. During the welding of the longitudinal beam body 1, one side plate and the bottom steel plate are first welded together. Then, multiple processing rings 2 are welded to the inner side of the vertical body assembled from the side plate and the bottom plate. Next, the other side plate and the top plate are welded to the outer side of the processing rings 2. Welding is used throughout the process for reinforcement. First, the crossbeam assembly blocks 31 at both ends of the crossbeam body 21 are installed inside the crossbeam assembly seats 25 on one side of the two longitudinal beam bodies 1. Then, assembly bolts 20 are threaded into the crossbeam assembly threaded holes 26 and 32. After assembly, gap welding is required between the crossbeam assembly blocks 31 and the crossbeam assembly seats 25, utilizing both bolts and welding for reinforcement. To improve the assembly effect between the crossbeams and longitudinal beams, a complete semi-trailer body is formed. This involves assembling multiple crossbeam bodies 21 and two longitudinal beam units 1 to form a complete semi-trailer body. During this process, it is necessary to ensure that the dimensions of the crossbeam assembly block 31 and the crossbeam assembly seat 25 are perfectly matched to avoid misalignment or excessive gaps, thus laying a solid foundation for subsequent fixing operations. The fixing support assembly plate 2 13 and the fixing support assembly threaded hole 22 are then connected together. Then, the fixing support 10 is connected to the longitudinal beam unit 1 using external bolts in conjunction with the fixing support assembly plate 1 23. The moving support assembly plate 1 7 and the moving support assembly plate 2 14 are then connected together. After completion, the moving support assembly plate 2 7 is connected to the longitudinal beam unit 1 using external bolts in conjunction with the moving support assembly threaded hole 24. The support bar 8 and the longitudinal beam 1 are assembled together. When a container needs to be placed on top of the semi-trailer, the four corners of the container can be installed inside the two movable end seats 11 and the two fixed end seats 3, respectively, so that the sides of the container contact the inner side of the movable support bar 8. The container is then fixed to the top of the semi-trailer using external bolts that engage with the end mounting threaded holes 4 and the side mounting threaded holes 5. This installation method is not only convenient and significantly reduces the labor intensity of workers, but also greatly improves work efficiency when the container needs to be disassembled or replaced; simply unscrewing the bolts is sufficient. Furthermore, the movable slider 29 can slide within the movable slide groove 15 to adjust the multiple movable support bar assembly plates. Position 14 allows adjustment of the positions of multiple movable support bars 8, thereby adjusting the positions of the fixed end seat 3 and the side mounting seat 18. This enables the semi-trailer body to adapt to containers of different lengths, significantly improving the versatility and effectiveness of the device and expanding its application range. The longitudinal beam 1 is internally equipped with reinforcing rings 2 made of high-strength materials, which effectively enhance the rigidity of the longitudinal beam 1, thereby improving the overall rigidity and load-bearing capacity of the entire semi-trailer body. When the semi-trailer body bears the weight of a container, the reinforcing rings 2 can distribute some stress, reducing the deformation of the longitudinal beam 1 and ensuring the structural stability of the semi-trailer body during long-term use. Simultaneously, the connecting block 27 inside the longitudinal beam 1 can slide freely within the reinforcing rings.Once the container is placed on the semi-trailer, its weight is distributed evenly, resulting in more uniform stress on all parts of the semi-trailer. This further improves the stability and lifespan of the semi-trailer, ensuring safety throughout the entire transportation or usage process.

[0028] In another implementation scheme, such as Figures 1-7 As shown, each of the crossbeam bodies 21 has a wire-threading block 16 fixedly installed at its bottom, and each wire-threading block 16 has a wire-threading groove 17 inside.

[0029] The wiring block 16 and wiring groove 17 make it easy to arrange the wires used in the later stages of the vehicle.

[0030] In another implementation scheme, such as Figures 1-7 As shown, reinforcing strips 12 are fixedly installed at the top and bottom of both the movable support 8 and the fixed support 10.

[0031] The rigidity of the movable support bar 8 and the fixed support bar 10 can be improved by setting them up, thereby reducing the risk of breakage when the movable support bar 8 and the fixed support bar 10 support the container.

[0032] Working principle: First, the crossbeam assembly blocks 31 at both ends of the crossbeam body 21 are installed inside the crossbeam assembly seats 25 on one side of the two longitudinal beam bodies 1. Then, by threading the assembly bolts 20 into the crossbeam assembly threaded holes 26 and 32, a complete semi-trailer body is formed between the multiple crossbeam bodies 21 and the two longitudinal beam bodies 1. During this process, it is necessary to ensure that the dimensions of the crossbeam assembly blocks 31 and the crossbeam assembly seats 25 are completely matched to avoid misalignment or excessive gaps, thus laying a solid foundation for subsequent fixing operations. Then, the fixing support assembly plate 2 13 and the fixing support assembly threaded hole 22 are connected together. Finally, the fixing support 10 is connected to the longitudinal beam body 1 by external bolts in conjunction with the fixing support assembly plate 23. The process begins by connecting the first and second movable support plate 14 together. After completion, the movable support 8 and the longitudinal beam 1 are assembled together using external bolts and threaded holes 24. When placing a container on top of the semi-trailer, the four corners of the container are installed inside the two movable end seats 11 and two fixed end seats 3, ensuring the sides of the container contact the inner sides of the movable support 8. The container is then fixed to the top of the semi-trailer using external bolts and threaded holes 4 and 5. This installation method is not only convenient and significantly reduces the workload of workers, but also allows for easy disassembly and replacement of the container by simply unscrewing the bolts. This greatly improves operational efficiency. Furthermore, the movable slider 29 can slide within the movable chute 15, thereby adjusting the position of multiple movable support assembly plates 14 and the positions of multiple movable support bars 8. This, in turn, adjusts the positions of the fixed end seat 3 and the side mounting seat 18, allowing the semi-trailer to adapt to containers of different lengths. During transport, the longitudinal inertial force is distributed across multiple fixed points at the bottom of the container to multiple movable support bars 8, rather than being concentrated on a single fixed support bar 10. The stress intensity is significantly reduced through this multi-point distribution. Additionally, when the semi-trailer is put into use, an external locking pin assembly needs to be installed on the outside of the longitudinal beam body 1. This assembly includes an inner pin cage, an outer pin cage, a locking pin, and an elastic element. The inner and outer pin cages are respectively attached to... On both the inner and outer sides of the longitudinal beam sidewall of the trailer, connecting bolts secure the locking pins. Elastic elements continuously provide outward thrust to the locking pins. When the trailer is adjusted to the target position, the locking pins can pass through the pin cage and the longitudinal beam through-hole and insert into the frame beam, locking the trailer to the frame. Limit pins prevent excessive movement of the locking pins, making assembly and disassembly convenient. This meets the needs of frequent trailer adjustments in trailers, significantly improving the versatility and effectiveness of the device and expanding its application range. Reinforcing rings 2 are installed inside the longitudinal beam 1. These reinforcing rings 2 are made of high-strength materials, effectively enhancing the rigidity of the longitudinal beam 1, thereby improving the overall rigidity and load-bearing capacity of the entire semi-trailer body. When the semi-trailer body bears the weight of a container, the reinforcing rings 2 can distribute some stress, reducing the deformation of the longitudinal beam 1.To ensure the semi-trailer body maintains structural stability during long-term use, the connecting blocks 27 inside the longitudinal beam 1 can slide freely within the reinforcing ring. When the container is placed on the semi-trailer body, the weight of the container is rationally distributed, making the stress on each part of the semi-trailer body more even, further improving the stability and service life of the semi-trailer body, and ensuring the safety of the entire transportation or use process. The wiring blocks 16 and wiring channels 17 facilitate the arrangement of wires to be used later in the vehicle. These features also enhance the rigidity of the movable support bars 8 and fixed support bars 10, reducing the risk of breakage when the movable support bars 8 and fixed support bars 10 support the container.
