Description

Technical Field

[0001] The present invention relates to the technical field of air transportation, and particularly relates to an expandable air transport vehicle. Background Art

[0002] With the acceleration of the urbanization process and the vigorous development of the social economy, air transportation is rising rapidly. Compared with the traditional ground transportation mode, air transportation breaks through the limitation of land resources, effectively releases the ground space, and greatly improves the space utilization efficiency. The air transport vehicle runs on the walking track suspended and supported by the ceiling, and can be flexibly designed into various forms such as straight line, curve, and loop. Users can freely plan the track laying scheme according to the actual route requirements, and achieve precise adaptation for complex industrial logistics transportation scenarios, and build an efficient and convenient air transportation network.

[0003] Based on the above, the existing air transport vehicles have the following deficiencies: Facing the track environments with different heights and complex layouts, their height adjustment and autonomous operation capabilities are insufficient, and it is difficult to flexibly adapt to diverse transportation scenarios. Moreover, the existing equipment is difficult to quickly adjust the load capacity of the carrying platform according to the size and weight of the goods, and cannot expand the carrying platform. When transporting irregular goods, it is unable to effectively adjust the center of gravity of the goods, and there is a risk of falling. At the same time, the versatility and fixed reliability of the carrying tool also need to be improved. In addition, due to the lack of effective lateral support, the running stability is insufficient, and the wear between the key components and the track is serious, restricting the service life of the equipment. Summary of the Invention

[0004] The present invention relates to an expandable air transport vehicle. An innovative slot and block quick connection structure is adopted between the expansion table and the expansion carrier, and with the double reinforcement design of the safety pull rod and the safety hook, the convenient expansion and stable connection of the carrying platform are achieved. Users can quickly adjust the carrying area and load capacity according to the actual transportation requirements, enabling the equipment to flexibly adapt to the transportation tasks of goods with different sizes and weights, greatly enhancing the versatility and practicality of the equipment. The adjustment component can achieve fine adjustment of the position of the expansion table. The operator can precisely control the telescopic movement of the adjustment pull rod by rotating the adjustment nut, and adjust the center of gravity of the goods in real time to ensure the dynamic balance during the transportation process, effectively avoiding the risk of goods falling. In addition, the fixed perforations opened in the expansion carrier and the expansion table can fix the carrier and can be replaced according to different transported items, comprehensively improving the safety and reliability of the transportation operation.

[0039] Specific usage method and function of this embodiment: In the present invention, the auxiliary roller 2 on the top of the aerial trolley 1 is embedded in the bottom beam track of the I-beam to ensure smooth sliding. By adjusting the intelligent electric cylinder 5 on the top of the auxiliary vehicle 4, the adjusting bracket 501 is controlled to insert into the connection hole 102 of the aerial trolley 1 and fixed with nuts to initially adjust the relative position between the aerial trolley 1 and the adjusting auxiliary vehicle 4. When transporting large or heavy goods, the connection card slot 1001 at the bottom of the extension platform 10 is aligned with the combined card slot 10401 of the extended loading platform 104, and pressed down to make them snap together. At the same time, the combined jack 1002 is sleeved on the combined card rod 10402, and then the extended connection block 12 is snapped into the extended pull slot 10301, and the length of the adjusting pull rod 15 in the extended pull rod 13 is changed by rotating the adjusting nut 14, so as to further strengthen the extended connection of the extension platform 10. Then, the hook at the top of the safety pull rod 11 is hung on the safety hook 10302 of the load connecting rod 103 to complete the installation and reinforcement of the extension platform 10, increasing the bearing area and load capacity. If there are changes in the track height during the transportation route or it is necessary to dock with loading and unloading stations at different heights, the height of the aerial trolley 1 can be adjusted by the telescopic movement of the intelligent electric cylinder 5 on the auxiliary vehicle 4 to drive the adjusting bracket 501 to rise and fall. The driving motor 7 is started, and the driving roller 6 is driven to rotate through the transmission bevel gear 8, the transmission rod 9 and the transmission worm 901, and the aerial transport vehicle runs autonomously along the track. During the transportation process, the auxiliary roller 2 continuously shares the lateral force to ensure smooth operation. After reaching the destination, the intelligent electric cylinder 5 can be operated in reverse to lower the height of the aerial trolley 1 to facilitate the loading and unloading of goods.
