[0023] Reference Figure 1~Figure 5, is an embodiment of the present invention, a multifunctional container transport semi-trailer frame is proposed, including a frame 1, a support frame 2 is arranged at the bottom of the frame 1, and a plurality of support frames 2 are arranged in sequence, the support frame 2 has a first through hole 201, a swing leg 3 is hingedly arranged at the lower end of the support frame 2, the swing leg 3 has a second through hole 301, after the swing leg 3 swings, the second through hole 301 is aligned with the first through hole 201 to form a first locking through hole 302, a first swing locking member 4 and a second swing locking member 5 are both swingably arranged at the bottom of the frame 1, and are respectively located on both sides of the support frame 2, the first swing locking member 4 and the second swing locking member 5 respectively have a first locking portion 401 and a second locking portion 501, after the first swing locking member 4 and the second swing locking member 5 swing, the first locking portion 401 and the second locking portion 501 are locked in the first locking through hole 302.

[0024] In this embodiment, a support frame 2 is designed. The support frame 2 is arranged at the bottom of the frame 1 and is arranged in sequence. The support frame 2 has a first through hole 201, which is used to form a first locking through hole 302 with the swing leg 3. The swing leg 3 is hinged at the lower end of the support frame 2 and has a second through hole 301. After the swing leg 3 swings, the second through hole 301 is aligned with the first through hole 201 to form the first locking through hole 302, which is used to insert a locking member to achieve fixation. The first swing locking member 4 and the second swing locking member 5 are both swingably arranged at the bottom of the frame 1, respectively located on both sides of the support frame 2. The first swing locking member 4 and the second swing locking member 5 have a first locking portion 401 and a second locking portion 501, respectively. After swinging, the first locking portion 401 and the second locking portion 501 are locked in the first locking through hole 302 to form a double-sided locking to ensure the stability of the swing leg 3. When it is necessary to dock or load and unload goods, the swing leg 3 swings to a suitable position so that the second through hole 301 is aligned with the first through hole 201 of the support frame 2 to form a first locking through hole 302. Then, the first swing locking member 4 and the second swing locking member 5 are operated to swing to the locking position, and the first locking portion 401 and the second locking portion 501 are inserted into the first locking through hole 302 to achieve bilateral locking of the swing leg 3, thereby ensuring the stability of the semi-trailer in a stationary state. The multifunctional container transport semi-trailer frame 1 proposed by the present invention significantly improves the locking effect of the support frame 2 and the swing leg 3 through the innovative design of the bilateral swing locking member, effectively prevents the loosening of the swing leg 3 under the action of external force, greatly improves the stability and operational safety of the semi-trailer in a stationary state, reduces the risk during transportation, and effectively improves the stability and operational safety of the semi-trailer in a stationary state by optimizing the locking structure of the support frame 2 and the swing leg 3.

[0025] Furthermore, the first locking through hole 302, the first locking portion 401 and the second locking portion 501 are all arc-shaped.

[0026] In this embodiment, when the swing leg 3 swings to the locking position, the second perforation 301 is precisely aligned with the first perforation 201 of the support frame 2, and together they form the second locking perforation 402. This perforation design ensures the accuracy and stability of the locking member when it is inserted, and effectively prevents the locking failure caused by poor perforation alignment. The first locking portion 401 of the first swing locking member 4 and the second locking portion 501 of the second swing locking member 5 are both designed to be arc-shaped. The advantage of the arc-shaped design is that when the locking portion is inserted into the locking perforation, a larger contact area can be provided, thereby forming a stronger locking force between the support frame 2 and the swing leg 3, significantly improving the stability and reliability of the locking structure. At the same time, the arc-shaped design also has adaptive capabilities, which can adapt to slight perforation alignment deviations to ensure the locking effect. When it is necessary to dock or load and unload goods, the swing leg 3 is first accurately swung to the locking position, at which time the second perforation 301 is aligned with the first perforation 201 of the support frame 2 to form the second locking perforation 402. Subsequently, the first swing locking member 4 and the second swing locking member 5 swing, so that the arc-shaped first locking portion 401 and the second locking portion 501 are accurately inserted into the second locking through-hole 402, thereby realizing the double-sided locking of the swing leg 3. The design of the arc-shaped locking portion ensures the smoothness of the locking process and the stability of the locking structure, and effectively improves the stability of the semi-trailer in a stationary state. By optimizing the design of the second locking through-hole 402 and adopting the arc-shaped locking portion, the stability and reliability of the locking structure are enhanced, and the loosening of the swing leg 3 under the action of wind or external force is effectively prevented, thereby improving the stability of the semi-trailer in a stationary state, reducing the risks during transportation, and improving the efficiency and safety of cargo transportation.

[0027] Furthermore, the first locking portion 401 is an arc-shaped sleeve type, having a second locking through hole 402, and the second locking portion 501 is an arc-shaped column. After the first swing locking member 4 swings, the first locking portion 401 passes through the first locking through hole 302, and after the second swing locking member 5 swings, the second locking portion 501 passes through the second locking through hole 402.

[0028] In this embodiment, the first locking portion 401 is designed as an arc-shaped sleeve-type structure, and a second locking through-hole 402 is provided inside. When the first swing locking member 4 swings to the locking position, the first locking portion 401 passes through the second locking through-hole 402 formed by the support frame 2 and the swing leg 3 to achieve a stable locking of the swing leg 3. The sleeve-type design not only provides sufficient strength, but also has a certain degree of adaptability, which can adapt to slight alignment deviations and ensure the locking effect. The second locking portion 501 is designed as an arc-shaped column structure. When the second swing locking member 5 swings to the locking position, the second locking portion 501 passes through the second locking through-hole 402 and cooperates with the first locking portion 401 to form a stable locking structure. The column design not only provides high strength, but also has good wear resistance and corrosion resistance, ensuring the long-term stability and reliability of the locking structure. When it is necessary to dock or load and unload goods, the operator ensures that the swing leg 3 is accurately swung to the locking position, at which time the second through hole 301 is aligned with the first through hole 201 of the support frame 2 to form a second locking through hole 402. Subsequently, the first swing locking member 4 is swung to allow the arc-shaped sleeve-shaped first locking portion 401 to pass through the second locking through hole 402; at the same time, the second swing locking member 5 is swung to allow the arc-shaped column-shaped second locking portion 501 to pass through the second locking through hole 402. The coordinated locking of the two ensures the stability of the swing leg 3 and effectively improves the stability of the semi-trailer in a stationary state. By adopting the arc-shaped sleeve-shaped first locking portion 401 and the arc-shaped column-shaped second locking portion 501, the stability and reliability of the locking structure are significantly enhanced, the loosening of the swing leg 3 under the action of external force is effectively prevented, the stability of the semi-trailer in a stationary state is improved, the risks during transportation and loading and unloading are reduced, and the safety of cargo transportation is improved.

[0029] Furthermore, the inner walls of the first locking hole 302 and the second locking hole 402 have a plurality of slots 403 and also include positioning beads 5. The outer walls of the first locking portion 401 and the second locking portion 501 are both provided with a plurality of positioning beads 5, and the positioning beads 5 are used to be stuck in the slots 403.

[0030] In this embodiment, the inner walls of the first locking through-hole 302 and the second locking through-hole 402 are both provided with a plurality of slots 403. The design of the slots 403 ensures that the positioning beads 5 are accurately embedded in the locking process, thereby improving the stability and reliability of the locking structure. The distribution and size of the slots 403 are carefully calculated to meet the locking requirements under different working conditions. The outer walls of the first locking portion 401 and the second locking portion 501 are both provided with a plurality of positioning beads 5. The design of the positioning beads 5 enables the positioning beads 5 to be accurately embedded in the slots 403 when the first locking portion 401 and the second locking portion 501 pass through the first locking through-hole 302 and the second locking through-hole 402, thereby forming a secondary locking effect, thereby further enhancing the stability and safety of the locking structure. When the first locking part 401 and the second locking part 501 pass through the first locking through hole 302 and the second locking through hole 402, the positioning bead 5 forms a tight mechanical bite with the slot 403, which not only provides additional locking force, but also plays a positioning role, ensuring the precise alignment of the locking structure, thereby significantly improving the locking effect and stability. By adding the slot 403 to the inner wall of the first locking through hole 302 and the second locking through hole 402, and setting the positioning bead 5 on the outer wall of the first locking part 401 and the second locking part 501, the secondary reinforcement of the locking structure is achieved, which significantly enhances the stability and reliability of the locking structure, effectively prevents the loosening of the swing leg 3 under the action of wind or external force, improves the stability of the semi-trailer in a stationary state, reduces the risk during transportation, and improves the efficiency and safety of cargo transportation.

[0031] Furthermore, it also includes a first linear drive member 6, one end of which is hinged to the frame 1, and the other end is hinged to the swing leg 3, driving the swing leg 3 to swing, the first gear 7 and the second gear 8 are respectively fixed on the first swing locking member 4 and the second swing locking member 5, and the driving gear 9 is rotatably set on the frame 1 and meshed with the first gear 7 and the second gear 8.

[0032] In this embodiment, the first linear drive member 6: one end is hinged to the frame 1, and the other end is hinged to the swing leg 3. The swing leg 3 is automatically swung by linear drive, replacing manual operation, and improving operation efficiency and safety. The first gear 7 fixedly set on the first swing locking member 4, the second gear 8 fixedly set on the second swing locking member 5, and the driving gear 9 rotatably set on the frame 1 form a gear set. The driving gear 9 is meshed with the first gear 7 and the second gear 8. Through the rotation of the driving gear 9, the first swing locking member 4 and the second swing locking member 5 are synchronously driven to swing, and automatic locking is achieved. When the locking operation is required, the operator starts the first linear drive member 6 to drive the swing leg 3 to automatically swing to the locking position. At the same time, through the rotation of the driving gear 9, the first gear 7 and the second gear 8 are synchronously driven to rotate, and then the first swing locking member 4 and the second swing locking member 5 are driven to swing, and automatic locking is achieved. The whole process does not require manual intervention, which greatly improves the operation efficiency and stability. This technical solution realizes the automatic swinging of the swing leg 3 and the synchronous locking of the locking member by introducing an automatic locking system, which significantly improves the operating efficiency, reduces the errors in manual operation, enhances the stability and reliability of the locking structure, effectively prevents the loosening of the swing leg 3 under the action of external force, improves the stability of the semi-trailer in a stationary state, reduces the risks during transportation, and improves the efficiency and safety of cargo transportation.

[0033] Furthermore, it also includes an articulated shaft 10, which is fixedly set on the swing leg 3, and the swing leg 3 is hinged to the support frame 2 through the articulated shaft 10. The first bevel gear 11 is set on the articulated shaft 10, and the second bevel gear 12 is coaxially set with the driving gear 9. The first bevel gear 11 drives the second bevel gear 12 to rotate.

[0034] In this embodiment, the hinge shaft 10 is fixedly arranged on the swing leg 3, and the swing leg 3 is hinged with the support frame 2 through the hinge shaft 10, so as to ensure the free swing of the swing leg 3. The first bevel gear 11 is arranged on the hinge shaft 10, and the swing leg 3 is driven to swing through the rotation of the first bevel gear 11, so as to achieve precise positioning. The second bevel gear 12 is arranged coaxially with the driving gear 9, and the second bevel gear 12 is driven to rotate through the rotation of the driving gear 9, and then the first bevel gear 11 is driven to rotate through the linkage of the bevel gear set, so as to achieve precise swing of the swing leg 3. When the swing operation of the swing leg 3 is required, the operator starts the driving gear 9, and while the driving gear 9 rotates, the second bevel gear 12 is driven to rotate through the coaxial arrangement with the second bevel gear 12. The second bevel gear 12 drives the first bevel gear 11 to rotate through the linkage of the bevel gear set, and then drives the swing leg 3 to swing precisely, so as to achieve precise positioning of the swing leg 3 and the stability of the locking structure. This technical solution realizes efficient linkage between the driving gear 9 and the swing leg 3 by introducing a helical gear transmission system, significantly improves operating accuracy, reduces errors in manual operation, enhances the stability and reliability of the locking structure, effectively prevents the swing leg 3 from loosening under the action of wind or external force, improves the stability of the semi-trailer in a stationary state, reduces risks during transportation, and improves the efficiency and safety of cargo transportation.

[0035] Furthermore, it also includes a third bevel gear 13, which is meshed with the first bevel gear 11, and a fourth bevel gear 14 is meshed with the second bevel gear 12. A transmission rod 15 is rotatably arranged on the support frame 2, and the third bevel gear 13 and the fourth bevel gear 14 are respectively arranged on the transmission rod 15.

[0036] In this embodiment, the third bevel gear 13 is meshed with the first bevel gear 11. Through the rotation of the third bevel gear 13, the power transmission range is further expanded and the transmission efficiency is improved. The fourth bevel gear 14 is meshed with the second bevel gear 12. Through the rotation of the fourth bevel gear 14, the linkage with the third bevel gear 13 is achieved, ensuring the effective transmission of power and multi-point linkage. The transmission rod 15 is rotatably set on the support frame 2. The third bevel gear 13 and the fourth bevel gear 14 are respectively set on the transmission rod 15. Through the rotation of the transmission rod 15, the synchronous rotation of the third bevel gear 13 and the fourth bevel gear 14 is achieved, thereby achieving the precise swing of the swing leg 3 and the stability of the locking structure. When the swing operation of the swing leg 3 is required, the operator starts the driving gear 9. While the driving gear 9 rotates, it drives the second bevel gear 12 to rotate through the coaxial setting with the second bevel gear 12. The second bevel gear 12 drives the fourth bevel gear 14 to rotate by meshing with the fourth bevel gear 14, and then drives the third bevel gear 13 to rotate by rotating the transmission rod 15, and finally drives the swing leg 3 to swing accurately by meshing with the first bevel gear 11, so as to achieve accurate positioning of the swing leg 3 and stability of the locking structure. This technical solution realizes multi-point linkage and efficient transmission by introducing an extended bevel gear transmission system, significantly improves operating efficiency and transmission efficiency, reduces energy loss, enhances the stability and reliability of the locking structure, effectively prevents the loosening of the swing leg 3 under the action of external force, improves the stability of the semi-trailer in a stationary state, reduces risks during transportation, and improves the efficiency and safety of cargo transportation.

[0037] Furthermore, it also includes a lifting platform 16 , which is arranged on the vehicle frame 1 , and the support frame 2 is arranged on the lifting platform 16 .

[0038] In this embodiment, the lifting platform 16 is arranged on the frame 1, and the support frame 2 is installed on the lifting platform 16. The lifting platform 16 can adjust the height of the frame 1 according to actual needs to achieve fast and safe loading and unloading of containers. During loading and unloading operations, the operator can adjust the lifting platform 16 to the corresponding position according to the height of the loading and unloading platform or the truck compartment, so that the support frame 2 and the loading and unloading surface are kept on the same horizontal line. In this way, whether loading or unloading containers, it can be carried out with almost no height difference, which greatly facilitates the operation of forklifts or cranes, improves loading and unloading efficiency, and reduces the risk of damage to goods and equipment. The introduction of the lifting platform 16 makes the loading and unloading operations no longer subject to height differences, and can be completed quickly and safely, thereby improving the overall operation efficiency. By adjusting the height of the lifting platform 16, it is ensured that the loading and unloading operations are carried out with almost no height difference, reducing the risk of damage to goods and equipment and improving the safety of the operation. The lifting platform 16 can adapt to different loading and unloading environments and conditions, whether it is a dock, a warehouse or an open field, it can be flexibly responded to, improving the applicability and flexibility of the semi-trailer.

[0039] Furthermore, a storage box 17 is provided at the bottom of the frame 1 .

[0040] In this embodiment, the storage box 17 is installed at the bottom of the frame 1, providing additional space for carrying tools, maintenance spare parts, safety equipment or small goods during transportation. The design of the storage box 17 takes into account the needs of waterproof, dustproof and anti-theft, ensuring the safety of the stored items. As an integral part of the frame 1, the storage box 17 moves with the semi-trailer. During transportation, the driver or staff can access the storage box 17 at any time to take out the required tools or materials for maintenance, inspection or emergency treatment in an emergency. The storage box 17 provides convenience for carrying additional items during transportation, improves the practicality of the semi-trailer, and enables the driver or staff to quickly obtain the required tools or materials when needed. By carrying safety equipment and maintenance tools, the storage box 17 indirectly improves the safety during transportation, ensures that a quick response can be made in an emergency, and reduces the risk of accidents. The design of the storage box 17 makes full use of the space at the bottom of the frame 1, does not occupy the main cargo loading area, improves space utilization, and enables the semi-trailer to carry additional items while transporting large containers.

[0041] Furthermore, the bottom of the swing leg 3 has a support member 18, and the bottom of the support member 18 has a protrusion 1801, and a plurality of protrusions 1801 are arranged in an array.

[0042] In this embodiment, the support member 18 is installed at the bottom of the swing leg 3 to increase the contact area with the ground and improve the support stability. The protrusions 1801 are arranged at the bottom of the support member 18, and each protrusion 1801 can penetrate into the ground, especially on soft or uneven ground, and can provide additional grip and stability. When the semi-trailer is docked or working, the swing leg 3 descends with the descent of the lifting platform 16, and the support member 18 contacts the ground. The design of the protrusion 1801 enables the support member 18 to better adapt to uneven ground, especially on soft or sandy ground, the protrusion 1801 can penetrate into the ground, provide additional support force, and prevent the semi-trailer from tilting or sliding due to poor ground conditions. The design of the protrusion 1801 significantly improves the stability of the semi-trailer under complex ground conditions and reduces the risk of sliding or tilting due to uneven or soft ground. The protrusion 1801 support member 18 can adapt to a variety of ground conditions, including sand, grass, muddy ground, etc., and improves the operating range and flexibility of the semi-trailer. By improving stability, the risk of accidents caused by ground conditions is reduced, maintenance and repair costs are reduced, and operational efficiency is improved.
