Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a multi-functional container transport skeleton semi-trailer includes a semi-trailer frame 1. The semi-trailer frame 1 is provided with a friction-reducing structure 2. The friction-reducing structure 2 includes a hydraulic rod 201 installed on the semi-trailer frame 1. An adjusting plate 202 is fixedly connected to the telescopic end of the hydraulic rod 201. A plurality of mounting seats 203 are installed on the adjusting plate 202. Two connecting plates 204 are fixedly connected to the mounting seats 203. A first connecting block 205 is fixedly connected to the connecting plate 204. A second connecting block 206 is slidably connected to the connecting plate 204. A ball bearing 207 is rolled between the first connecting block 205 and the second connecting block 206.

[0025] As a technical optimization of this utility model, a guide plate 208 is fixedly connected to the semi-trailer frame 1, and an adjusting plate 202 is slidably connected to the guide plate 208. While the container is being loaded and unloaded by the lifting equipment, the hydraulic rod 201 can be activated. When the telescopic end of the hydraulic rod 201 extends, it drives the adjusting plate 202 to move upward. When the adjusting plate 202 moves, it will slide with the guide plate 208. The setting of the guide plate 208 makes the movement of the adjusting plate 202 more stable. At the same time, the adjusting plate 202 drives the ball bearing 207 to move upward. When the ball bearing 207 moves upward to a certain position, the container on the semi-trailer frame 1 will roll and cooperate with the ball bearing 207. The setting of the ball bearing 207 avoids the large friction between the container and the semi-trailer frame 1 during the loading and unloading process, which would lead to loading and unloading difficulties and prolong the loading and unloading time. At the same time, it avoids wear on the structure of the container and the semi-trailer frame 1. In addition, the ball bearing 207 can be raised and lowered, and can be retracted into the semi-trailer frame 1 when not in use, so as not to affect the container during transportation.

[0026] As a technical optimization of this utility model, the second connecting block 206 is adjusted by an adjustment structure 3. The adjustment structure 3 includes an adjustment rod 301 fixedly connected to the second connecting block 206, a locking block 302 slidably connected inside the adjustment rod 301, two slots 303 provided on the connecting plate 204, the locking block 302 engaging with one of the slots 303, a slider 304 fixedly connected to the locking block 302, the slider 304 slidably connected to the adjustment rod 301, a lead screw 305 rotatably connected inside the adjustment rod 301, and the slider 304 threadedly connected to the lead screw 305. Furthermore, when it is necessary to adjust the ball bearing 2... When replacing 07, an internal hex wrench can be inserted into the internal hexagonal groove on the lead screw 305. By rotating the lead screw 305, the threaded slider 304 slides. When the slider 304 slides, the locking block 302 is no longer engaged with the locking groove 303. The locking block 302 engages with the locking groove 303 on the connecting plate 204, which facilitates the fixing of the sliding adjusting rod 301, thereby improving the stability of the second connecting block 206. At this time, the adjusting rod 301 can be used to drive the second connecting block 206 to slide away from the first connecting block 205. After the second connecting block 206 slides to a certain position, the ball bearing 207 can be removed for replacement.

[0027] As a technical optimization of this utility model, the semi-trailer frame 1 is provided with a storage structure 4. The storage structure 4 includes a storage box 401 installed on the semi-trailer frame 1. Two connecting strips 402 are fixedly connected to the storage box 401. A rotating shaft 403 is rotatably connected between the two connecting strips 402. A protective door 404 is fixedly connected to the rotating shaft 403. A threaded sleeve 405 is fixedly connected to the upper connecting strip 402. A screw 406 is threadedly connected to the threaded sleeve 405. A plug rod 407 is fixedly connected to the bottom of the screw rod 406. A slot 408 is provided on the protective door 404. The plug rod 407 and the slot 408 are connected to each other. The screw 406 is fixedly connected to a rotating rod 409, which is perpendicular to the screw 406. Maintenance tools can be placed in the storage box 401. The protective door 404 drives the rotating shaft 403 to rotate. When the protective door 404 rotates to be parallel to the connecting strip 402, the rotating rod 409 can be rotated, causing the screw 406 to rotate. The screw 406 then engages with the threaded sleeve 405, causing the insertion rod 407 to insert into the slot 408. This insertion of the insertion rod 407 into the slot 408 facilitates the fixing of the rotated protective door 404, improving stability. Furthermore, the storage box 401 facilitates the storage of maintenance tools.

[0028] In use, while the container is being loaded and unloaded by the lifting equipment, the hydraulic rod 201 can be activated. When the telescopic end of the hydraulic rod 201 extends, it drives the adjusting plate 202 to move upward. As the adjusting plate 202 moves, it slides against the guide plate 208. The guide plate 208 ensures smoother movement of the adjusting plate 202. Simultaneously, the adjusting plate 202 drives the ball bearings 207 to move upward. When the ball bearings 207 reach a certain position, the container on the semi-trailer frame 1 will roll and adjust its position relative to the ball bearings 207. The ball bearing 207, through its design, avoids excessive friction between the container and the semi-trailer frame 1 during loading and unloading, preventing difficulties and extended loading and unloading times. It also avoids wear and tear on the structure of the container and the semi-trailer frame 1. Furthermore, the ball bearing 207 can be raised and lowered, retracting into the semi-trailer frame 1 when not in use, preventing any impact on the container during transport. When the ball bearing 207 needs replacement, an internal hexagonal wrench can be inserted into the internal hexagonal groove on the lead screw 305, and the lead screw 305 can be rotated to replace it. When 305 rotates, the threaded drive slider 304 slides. As slider 304 slides, it causes block 302 to no longer engage with slot 303. Block 302 engages with slot 303 on connecting plate 204, facilitating the fixation of the slidable adjusting rod 301, thus improving the stability of the second connecting block 206. At this point, the adjusting rod 301 can drive the second connecting block 206 to slide away from the first connecting block 205. After the second connecting block 206 slides to a certain position, the ball bearing 207 can be removed for replacement. Simultaneously, maintenance tools can be used. Place it inside the storage box 401, and then drive the rotating shaft 403 to rotate through the protective door 404. When the protective door 404 rotates to be parallel with the connecting strip 402, the rotating rod 409 can be rotated, which will drive the screw 406 to rotate. The screw 406 will cooperate with the threaded sleeve 405, driving the insertion rod 407 to be inserted into the slot 408. The insertion of the insertion rod 407 into the slot 408 makes it easy to fix the rotated protective door 404, improving stability. The storage box 401 also facilitates the storage of maintenance tools.
