[0046] Figure 1 This is a schematic diagram of a quick-change loading and unloading device according to one embodiment of the present invention. Figure 2 This is a schematic diagram of a floating arm assembly according to one embodiment of the present invention. Figure 6 This is a schematic diagram illustrating the loading and unloading of a large-corner tank container according to one embodiment of the present invention. Figure 7 This is a schematic diagram of loading and unloading a small corner fitting tank container according to one embodiment of the present invention. In this diagram, the quick-change loading and unloading device includes a fixed arm 1 and two sets of floating arm assemblies 2. The two sets of floating arm assemblies 2 are symmetrically arranged at both ends of the fixed arm 1 and are engaged with the fixed arm 1. Further, to achieve the fixing of tank containers with corner fittings of different specifications, the floating arm assembly 2 includes a floating arm 21, two sets of guide plate assemblies 22, and two sets of rotating assemblies 23. A spreader assembly 24 is provided at the top of the floating arm 21, which is used to engage with the corner fitting holes on the tank container for locking and fixing. The two sets of guide plate assemblies 22 are arranged vertically on the same side wall of the floating arm 21. The two sets of rotating assemblies 23 are arranged vertically on the corresponding guide plate assembly 22 or on the side wall of the floating arm 21, and are used to rotate synchronously to move away from or cover the corresponding guide plate assembly 22.

[0047] Compared with the prior art, this utility model first designs a basic floating arm 21 for large-sized corner-part tank containers. The vehicle is moved to the front of the tank container until the guide plate assembly 22 at the upper end of the floating arm 21 contacts the upper part of the tank container. Then, the spreader is lowered to lock the tank container in place, while the lower end of the floating arm 21 contacts the lower part of the tank container to prevent swaying during loading and unloading. When loading and unloading small-sized corner-part tank containers, the rotating assembly 23 is rotated 180° by operating a button in the cab. The vehicle is then moved to the front of the tank container until the rotating assembly 23 at the upper end of the floating arm 21 contacts the tank container body. The spreader is then lowered to lock the tank container in place, while the rotating assembly 23 at the lower end of the floating arm 21 contacts the lower part of the tank container to prevent swaying during loading and unloading. Compared with the prior art, this utility model can position and fix tank containers with corner brackets of different specifications, so that the spreader assembly 24 can accurately match the corner bracket holes of various sizes, which solves the limitation of traditional spreaders that can only fix a single specification, and improves the diversity and efficiency of loading and unloading.

[0048] Furthermore, the specific structure of the guide plate assembly 22 can be various designs known to those skilled in the art, provided that it achieves the limiting of the large-sized corner tank container. In one example of this utility model, the two sets of guide plate assemblies 22 include guide plates and / or guide seats.

[0049] In this embodiment, the specific structure of the rotating assembly 23 can be various that are known to those skilled in the art. In a preferred example of this invention, such as... Figure 3 As shown, the rotating assembly 23 includes a rotating bracket 231, a rotating bracket 232, a connecting plate 233, and a positioning plate 234. The rotating bracket 231 is mounted on the guide seat or floating arm 21. One end of the rotating bracket 232 is hinged to the rotating bracket 231. One end of the connecting plate 233 is connected to the other end of the rotating bracket 232 and is perpendicular to the rotating bracket 232. The positioning plate 234 is located on the side of the connecting plate 233 away from the rotating bracket 232 and close to the other end of the connecting plate 233. The positioning plate 234 rotates around the rotating bracket 231 to limit the movement of small-sized corner-mounted tank containers. The positioning plate 234 directly engages with the container's contact surface, working synergistically with the corner-mounted locking mechanism of the spreader assembly 24 to effectively suppress container swaying during lifting and improve locking stability.

[0050] To improve the accuracy of positioning small-sized corner tank containers, in this embodiment, the rotating assembly 23 also includes an adjusting shim 235. This adjusting shim is located between the connecting plate 233 and the positioning plate 234 and is used to adjust the distance between the positioning plate 234 and the connecting plate 233.

[0051] In this embodiment, the hinge connection between the rotating bracket 232 and the rotating bracket 231 can be any of those known to those skilled in the art. In one example of this invention, the rotating bracket 232 is connected to the rotating bracket 231 via a rotating pin 236. Further, the rotating pin 236 is connected to the rotating bracket 232 via bolts. The rotating pin 236 serves as the hinge core between the rotating bracket 232 and the rotating bracket 231, providing a reliable rotation fulcrum.

[0052] In this embodiment, the method of driving the rotating assembly 23 to rotate can be various that are known to those skilled in the art. In a preferred example of this invention, such as... Figure 4 and Figure 5 As shown, the rotating assembly 23 also includes a motor assembly 25, which is mounted on the floating arm assembly 2. The motor assembly 25 includes a motor mounting plate 251 and a rotary motor 252. The motor mounting plate 251 is fixedly connected to the floating arm 21. The rotary motor 252 is mounted on the motor mounting plate 251 and connected to the rotating pin 236. When limiting the movement of a large-corner tank container, the control button in the cab rotates the rotary motor 252 to the right, causing the rotating assembly 23 to rotate away from the tank container. When limiting the movement of a small-corner tank container, the control button in the cab rotates the rotary motor 252 to the left, causing the rotating assembly 23 to rotate towards the tank container. The upper rotating bracket 232 contacts the upper guide plate assembly 22, and the lower rotating bracket 232 contacts the lower guide plate assembly 22. After switching, the positioning plates 234 of the two rotating mechanism assemblies are at the foremost position, and the mode switch is complete. In addition, after the rotary assembly 23 is assembled on the floating arm 21 body assembly, the rotary motor 252 and the rotary pin 236 are connected by a flat key.

[0053] In this embodiment, to ensure the rotational accuracy of the rotating assembly 23, the quick-change loading and unloading device further includes a detection component 26. The specific structure of the detection component 26 can be varied and known to those skilled in the art. In a preferred embodiment of this invention, the detection component 26 includes two sets of proximity switch brackets and two sets of proximity switches. The two sets of proximity switch brackets are respectively mounted on one of the guide plate assemblies 22 and on the side of the floating arm 21 away from the corresponding guide plate assembly 22. The two sets of proximity switches are respectively mounted on the corresponding proximity switch brackets and are used to identify the position of the detection positioning plate 234 to control the rotational motor 252 to shut off. During the installation of the large corner piece tank container, the rotational motor 252 drives the rotating assembly 23 to rotate away from the tank container until the distance to the corresponding proximity switch is within 5mm. At this point, the proximity switch activates, cutting off the power to the rotational motor 252, and both the upper and lower rotational motors 252 stop moving. When installing the small corner fitting tank container, the rotary motor 252 drives the rotary assembly 23 to rotate towards the tank container until the distance to the corresponding proximity switch is 5mm. At this point, the proximity switch activates and cuts off the power to the rotary motor 252, and both the upper and lower rotary motors 252 stop moving.

[0054] After the tank container is positioned, it is locked using the spreader assembly 24. The specific structure of the spreader assembly 24 can be varied and known to those skilled in the art. In a preferred embodiment of this invention, the spreader assembly 24 includes a lock head fixing plate 241 and a lock head 242. The lock head fixing plate 241 is located at the top of the floating arm 21 and has mounting holes. The lock head 242 is positioned within the mounting holes and is inserted into the corner fitting holes to lock the tank container. The lock head 242 is lowered into the mounting holes of the lock head fixing plate 241, accurately falling into the corner fitting holes on the top of the container. The operating handle of the lock head 242 is manipulated to rotate the lock head 242 90°, fixing it in the corner fitting holes on the upper part of the tank container. The locking operation of the tank container is achieved by rotating the lock head 242 using a rotary locking cylinder.

[0055] In this embodiment, the connection method between the positioning plate 234 and the connecting plate 233 can be one of various methods known to those skilled in the art. In one example of this utility model, for ease of assembly and disassembly, the positioning plate 234 and the connecting plate 233 are connected by multiple sets of internal hexagonal bolts. This multiple-set internal hexagonal bolt connection not only ensures the stability of the connection but also facilitates timely replacement of the worn positioning plate 234.

[0056] On the other hand, this utility model provides a dual-mode tank container loading and unloading quick-change system, which includes a spreader vehicle and any of the above-mentioned loading and unloading quick-change devices, and the loading and unloading quick-change device is set at the lifting connection of the spreader vehicle.

[0057] Through the above technical solution, this utility model provides a dual-mode tank container loading and unloading quick-change device and system. It uses two sets of guide plate assemblies to limit and fix tank containers with large corner fittings, and two sets of rotating assemblies to limit and fix tank containers with small corner fittings. Furthermore, it employs a spreader assembly that engages with the corner fitting holes on the tank container for locking and fixation. Compared with existing technologies, this utility model can position and fix tank containers with corner fittings of different specifications, allowing the spreader assembly to accurately match corner fitting holes of various sizes. This overcomes the limitation of traditional spreaders that can only fix a single specification, improving the diversity and efficiency of loading and unloading.

[0058] The optional embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the embodiments of the present utility model are not limited to the specific details in the above embodiments. Within the scope of the technical concept of the embodiments of the present utility model, various simple modifications can be made to the technical solutions of the embodiments of the present utility model, and these simple modifications all fall within the protection scope of the embodiments of the present utility model.

[0059] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the various possible combinations will not be described separately in this embodiment.

[0060] Furthermore, various different embodiments of this utility model can be combined arbitrarily, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
