[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a rising sealing docking device, which is arranged at the upper port of the lower container and is used for sealingly docking the lower container and the upper container, including a fixing frame 1, an airbag 2, a lifting plate 3 and a docking flange 4. The fixing frame 1 and the airbag 2 are both provided with two, the two fixing frames 1 are fixedly connected to the two sides of the upper opening of the lower container, the airbag 2 is provided with a charging and discharging port, the lower ends of the two airbags 2 are respectively fixedly connected to the upper surfaces of the two fixing frames 1, the two ends of the lifting plate 3 are respectively fixedly connected to the upper ends of the two airbags 2, a supporting ring 5 is fixedly provided in the middle of the lifting plate 3, the docking flange 4 is adjustably connected to the supporting ring 5, the outer diameter of the upper end of the docking flange 4 is larger than the outer diameter of the supporting ring 5, and the lower end of the docking flange 4 is softly connected to the inlet of the lower container.

[0018] In this embodiment, the rising sealed docking device provided by the utility model is used for transmitting granular or powdered materials between the upper container and the lower container. The device is connected to the upper port of the lower container through a hose or a cloth bag. When docking is required, air is inflated into the airbag 2 through the inflation and deflation port, and the airbags 2 on both sides rise, thereby pushing the lifting plate 3 to rise. The lifting plate 3 drives the docking flange 5 to rise through the support ring 4. The upper end of the docking flange 5 completes a sealed docking with the lower port of the upper container. At this time, the material can be transmitted. When the transmission is completed, the airbag 2 is deflated through the inflation and deflation port, the height of the airbag 2 decreases, driving the lifting plate 3 to descend. The lifting plate 3 drives the docking flange 5 to descend through the support ring 4, and the docking flange 5 at the lower port of the upper container is separated.

[0019] In order to make the lifting plate 3 rise or fall stably and limit the maximum rising height of the lifting plate 3, as an improvement of the technical solution, a guide column 6 is respectively provided on the fixing frame 1 on both sides of the airbag 2, and the two ends of the lifting plate 3 are respectively movably connected to the guide columns 6 on both sides, and the upper ends of the two guide columns 6 on the same side are fixedly connected to a limit plate 7.

[0020] Preferably, the guide column 6 is divided into three sections, the diameter of the lower section of the three-section guide column 6 is the largest, and the diameter of the upper section is the smallest, the lifting plate 3 is movably mounted on the guide column 6 in the middle section, and the limit plate 7 is fixedly connected to the lower end of the guide column 6 in the upper section.

[0021] In order to make the lifting plate 3 more stable when docking is not required, as an improvement of the technical solution, a lower hanging plate 8 is fixed on the front and rear sides of each of the fixing frames 1, and upper hanging plates 9 are provided on the front and rear sides of both ends of the lifting plate 3 and at positions corresponding to the upper and lower hanging plates 8, and a spring 10 is connected between the upper hanging plate 9 and the lower hanging plate 8 on the same side.

[0022] After the docking work is completed, the airbag 2 is deflated through the inflation and deflation port, the height of the airbag 2 decreases, and at the same time, the spring 10 pulls the lifting plate 3 down through the upper hanging plate 9. During the whole process, the spring 10 is in a pulled up state, giving the lifting plate 3 a downward pulling force. When the airbag 2 is inflated, the upward thrust of the airbag 2 is greater than the pulling force of the spring 10.

[0023] In order to compensate for the insufficient lifting height of the airbag 2, as an improvement of the technical solution, a plurality of screws 11 are fixedly provided on the lower surface of the docking flange 4, and the same number of through holes are provided on the lifting plate 3. Each screw 11 passes through a through hole and is fixed in position by nuts on both sides of the through hole.

[0024] When encountering an upper container and a lower container with a port distance that differs too much, the distance between the docking flange 4 and the lifting plate 3 is adjusted by the screw rod 11 and fixed by the nut.

[0025] In order to increase the sealing performance, as an improvement, a sealing ring 12 is provided at the upper end of the docking flange 4 .

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
