Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading cargo, in particular to a rapid loading and unloading device for a container. Background Art

[0002] A container is a large cargo container with standardized size and structure. It plays a vital role in modern logistics. As an indispensable part of modern logistics, its standardized and modular characteristics and wide range of applications enable it to play an important role in improving logistics efficiency, ensuring cargo safety, reducing losses and pollution, etc.

[0003] In the process of using containers for logistics transportation, loading and unloading platforms are usually used to move the goods out of the containers. Existing loading and unloading platforms are fixed with a buffer plate with a chain on the side that docks with the container, so that carts and goods can more easily reach the loading and unloading platform. However, when the buffer plate is tilted upward or flipped to a vertical position for retraction, the connected chain will be in a loose state, which may hinder the movement of goods and personnel. At the same time, after the buffer plate is retracted, the chain is exposed outside, which accelerates the aging of the chain, thus posing a certain risk. To this end, we proposed a rapid loading and unloading device for containers to effectively solve the above-mentioned drawbacks. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 A rapid loading and unloading device for containers includes a loading and unloading platform 1. The front side of the loading and unloading platform 1 is rotatably connected to a buffer plate 2. Chains 201 are fixedly welded to the left and right sides of the buffer plate 2 near the front end, so that workers can extend the chains 201 to tilt the buffer plate 2 outward, so that the buffer plate 2 can be placed on the container to provide a buffering effect for the movement of goods. Side frames 3 are fixedly provided on the left and right sides of the loading and unloading platform 1. Guide rails 4 installed in the vertical direction are slidably provided on both side frames 3. Lifting mechanisms 5 for controlling the lifting of the loading and unloading platform 1 are fixedly installed on both guide rails 4. When the lifting mechanism 5 drives the loading and unloading platform 1 and the side frames 3 to lift, the sides of the loading and unloading platform 1 will slide up and down along the guide rails 4, making the lifting more stable. The front side of the side frame 3 is provided with a receiving slot 301 for inserting the chain 201. One end of the chain 201 is slidably connected to the receiving slot 301, so that the chain 201 can be stored in the receiving slot 301. This prevents the chain 201 from being exposed to air for a long time when the buffer plate 2 is not in use, thereby extending its service life. The depth of the receiving slot 301 is no less than the length of the chain 201, so that the chain 201 can be completely stored in the receiving slot 301. One end of the chain 201 located in the receiving slot 301 is fixedly connected to the limiting assembly 6. When the buffer plate 2 is tilted at a certain angle, the limiting assembly 6 can be fixed and limited in position within the receiving slot 301. This keeps the chain 201 in a taut state and prevents it from extending to the sides due to relaxation, thereby avoiding obstruction to the movement of goods and personnel.

[0021] Furthermore, the limiting assembly 6 includes a slider 601, which is fixedly connected to the inner end of the chain 201 and slides with the receiving groove 301. The movement of the slider 601 can drive the chain 201 to move in the receiving groove 301. The limiting assembly 6 also includes a driving groove 602, a spring 604, a limiting block 605 and an extension block 606. The driving groove 602 is provided in the slider 601 and passes through the front side wall and the lower side wall of the slider 601. One end of the spring 604 abuts against the top of the inner wall of the driving groove 602, and the other end of the spring 604 abuts against the limiting block 605 slidably connected in the driving groove 602, so that the limiting block 605 can move in the driving groove 602 under the action of the spring 604. The extension block 606 is fixedly connected to the front of the limit block 605 and extends to the outside of the driving slot 602, so that when the spring 604 pops the limit block 605 outward of the driving slot 602, the extension block 606 will stop the limit block 605 from continuing to pop out after moving a certain distance, thereby preventing the limit block 605 from detaching from the driving slot 602.

[0022] Furthermore, a sliding groove 302 is provided on the inner side walls of the two side frames 3, and a stabilizing block 603 is provided on the back of the slider 601. The stabilizing block 603 and the sliding groove 302 are slidably connected so that when the slider 601 moves in the storage groove 301, the stabilizing block 603 will move in the sliding groove 302, thereby making the movement of the slider 601 more stable.

[0023] Furthermore, a limit plate 7 is fixedly provided on the inner side wall of the side frame 3 and at the lower side position of the slide groove 302. The limit plate 7 is provided with a limit groove 701 for the limit block 605 to be movably inserted, so that when the limit block 605 moves to the position of the limit groove 701, the limit block 605 will be popped out by the spring 604 and enter the limit groove 701, thereby fixing the limit assembly 6, so that the chain 201 will not be in a loose state.

[0024] After the lifting of the lifting mechanism 5, the chain 201 will not be loosened to the sides, thereby avoiding obstruction to the movement of goods and staff, and facilitating the transportation of goods. After the lifting of the lifting mechanism 5, the chain 201 will be loosened to the sides, thereby avoiding obstruction to the movement of goods and staff, and facilitating the transportation of goods.
