Detailed Implementation

[0052] Please refer to Figures 1 to 8The attachment 207 used for loading and unloading multimodal transport containers includes a first frame 203, a tilting frame 205, a slewing drive mechanism 201, a lifting frame that can be connected to the multimodal transport container, and a lifting cylinder 204. The tilting frame 205 can be tilted and connected within the first frame 203; the rotary drive mechanism 201 is connected to the tilting frame 205; the lifting frame can be connected to container A in multimodal transport, and the lifting frame can be slidably connected to the tilting frame 205; the lifting cylinder 204 connects the tilting frame 205 and the lifting frame, the lifting cylinder 204 includes a cylinder body 2041 and a piston rod 2042 slidably connected to the cylinder body 2041 and drives the lifting frame to rise and fall through the lifting cylinder 204, the piston rod 2042 of the lifting cylinder 204 is inclined relative to the cylinder body 2041 in the direction of downward bias towards container A, the lifting cylinder 204 has a clamping part 2043 that gradually moves inward to tightly engage the container during the process of the lifting cylinder 204 driving the lifting frame to rise, the clamping part 2043 may be separately fixed to the friction pad of the lifting cylinder 204, or it may only be the part of the lifting cylinder 204 that contacts the container. In the specific structure: at least one pair of lifting cylinders 204 are provided. The upper end of the piston rod of the lifting cylinder 204 is rotatably connected to the tilting frame 205. The upper or middle part of the cylinder body of the lifting cylinder 204 is rotatably connected to the lifting frame. The two lifting cylinders 204 are arranged in an inverted V-shape. The opposing sidewalls of the cylinder bodies of the two lifting cylinders 204 have the aforementioned clamping parts 2043. During the lifting process, the two cylinder bodies rotate inward relative to the rotation point of the lifting frame, thereby causing the clamping parts 2043 to gradually move inward to clamp the container A. Thus, the lifting mechanism can not only achieve lifting drive to lift the container A, but also clamp the container A during the lifting process, improving the stability and firmness of the container during the tilting process. The attachments of this embodiment can not only be applied to the loading and unloading machine of this embodiment, but can also be used in conjunction with other engineering vehicles to achieve the function of unloading containers.

[0053] The first frame 203 includes a main beam 2031 and two vertical beams 2032 respectively fixed at both ends of the main beam 2031. The tilting frame 205 is tiltable and connected between the two vertical beams 2032. The rotary drive mechanism 201 is installed inside the vertical beams. The lifting frame includes a lower frame 202. The tilting frame 205 includes two tilting seats 2052, a U-shaped upper frame 2053 fixed on the two tilting seats 2052, and two cooperating beams 2051. The two cooperating beams 2051 and the upper frame 2053 are fixedly arranged relative to each other, and the two cooperating beams 2051 are respectively located directly below the two rods of the upper frame 2053. The distance between the two cooperating beams 2051 is adapted to the width of the container. The lower frame 202 is provided with a lug 2025, and the lifting cylinder 204 is rotatably connected to the lug 2025. The lower frame 202 is provided with a rotary locking structure 2023. By using a beam, the stability and robustness of the container can be improved during the flipping process.

[0054] The lower frame 202 is provided with a slide 2024, and the flipping seat 2052 is provided with a lifting slide groove. The slide 2024 is slidably connected to the lifting slide groove. The slide 2024 is provided with a first roller 2021 with its axis arranged along a first direction and a second roller 2022 with its axis arranged along a second direction. The first roller 2021 and the second roller 2022 are connected to the lifting slide groove. The first direction and the second direction are perpendicular to the lifting direction of the lifting frame, which reduces friction and improves the smoothness of lifting.

[0055] During use, the lower frame 202 is connected to the container, and the lifting cylinder 204 drives the lifting frame to rise. After rising to the position, the tilting frame 205 tilts to unload the bulk cargo from the container.

[0056] The working attachment of this embodiment is applied in railway multimodal transport, such as connecting the working attachment to a loading and unloading machine. The loading and unloading machine includes a car body, a lifting mechanism, the aforementioned attachment 207, and a rotation drive mechanism. The lifting mechanism is mounted on the car body and has a lifting seat that can be raised and lowered vertically. The first frame 203 is rotatably connected to the lifting seat. The rotation drive mechanism is connected to the first frame 203 to drive the attachment 207 to rotate vertically, that is, horizontally. Therefore, in this embodiment, the first frame 203 is also a horizontally rotating frame 203, and the attachment 207 is also a horizontally rotating attachment. The rotation drive mechanism is such as a motor or a hydraulic motor. By rotating the first frame 203 and vertically lifting the hoisting seat, this loading and unloading machine can directly cooperate with the F-TR lock (rotary lock) on the railway flatcar to load and lock the hoisted container A onto the railway flatcar, or unlock and lift the container A off the railway flatcar; the car body itself can also transport the container to a designated location or from other locations to the railway flatcar, playing a role in off-road transportation; and with the tilting frame, it can unload the bulk cargo inside the container. The lifting mechanism includes a lifting cylinder, a boom, a boom cylinder, and a boom structure. The boom structure includes a base boom, a telescopic boom slidably connected to the base boom, and a telescopic drive component. The telescopic drive component connects to the telescopic boom and drives it to slide relative to the base boom to achieve extension and retraction. The telescopic boom is equipped with the aforementioned lifting seat, and the corner fitting holes on the container are aligned via a boom retraction auxiliary twist-lock structure. The first end of the lifting cylinder is rotatably connected to the vehicle body, and the second end is rotatably connected to the base boom. The boom has two first connecting arms and a second connecting arm that fit together in an inverted V-shape. One first connecting arm is rotatably connected to the vehicle body. The first end of the boom cylinder is rotatably connected to the vehicle body, and the second end is rotatably connected to the other first connecting arm. The second connecting arm is rotatably connected to the base boom. The connection positions of the second end of the lifting cylinder and the second connecting arm to the base boom are arranged relative to the boom structure. The above-mentioned structure allows for control of the vertical lifting of the lifting seat, and the entire vehicle structure remains stable and reliable while ensuring transport capability. Furthermore, it also includes a leveling cylinder, the first end of which is rotatably connected to the lifting base, and the second end of which is rotatably connected to the first frame. During container lifting or transport, the leveling cylinder ensures that the tilting frame and the container will not sway during lifting, lowering, or transport. Furthermore, it also includes a translation cylinder 206 and a rotating component 208. The rotating component is rotatably connected to the lifting base, and a rotation drive mechanism, such as a motor or hydraulic motor, is connected to the rotating component. The first frame is horizontally connected to the rotating component. The first end of the translation cylinder is connected to the rotating component, and the second end of the translation cylinder is connected to the first frame. The translation cylinder drives the attachment to translate relative to the rotating component. The translation cylinder also assists the rotary lock structure on the lower frame in aligning with the corner fitting holes on the container, improving the accuracy of unlocking and locking.

[0057] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification of the present invention should still fall within the protection scope of the present invention.
