实际使用时，各部件按照上述位置关系连接后，将需要进行空投的物资码放于平台主体1上表面，用专用网兜或绳索，在位于平台主体1靠近四个侧面边沿的系留捆绑孔3和位于相对中部的四个活节螺栓13处，进行穿束紧固，其中需着重保护的物资码放在平台主体1的中部，通过四个活节螺栓13先进行穿束紧固，这样在空降过程中，出现倾斜和剧烈摇晃时产生的离心力能够相对得以减小，对物资能够起到一定的保护作用，着陆时，由于各个减震双排万向轮4中均设有弹簧减震装置41，能够起到一定的缓冲作用，使得整个空降平台不会轻易遭受冲击而损坏，能够增加重复使用的次数，此外，各个减震双排万向轮4中设置的双轮高度自调节装置42，能够在路面不平整度一定范围内进行高度自动调节的补偿，使牵引运输时相对平稳，具体的原理是：装置主体421中的左侧燕尾槽和右侧燕尾槽配合第一齿条422和第二齿条423，共同与齿轮424相互啮合，第一齿条422和第二齿条423分别通过万向轴承45连接一副滚轮，当其中的一副滚 轮先接触地面时，由于受垂直下压力的作用，立轴413装置主体421一起向下滑动，同时因为先接触地面一侧的滚轮有向上的反作用力，故而迫使立轴413所连接的齿轮424需朝向未接触地面一侧的滚轮方向转到，以平衡两个方向的受力，此时，通过齿轮啮合的关系，促使没有接触地面的滚轮上方的齿条向下滑动，直到另一侧的滚轮也接触到地面至两侧竖向力均衡为止，不过通常能够调整补偿的范围具有局限性，在地面相对平整度较差的情况下，依然只能依靠单滚轮受力运输。In actual use, after the components are connected according to the above positional relationship, the materials that need to be air-dropped are placed on the upper surface of the platform main body 1, and special net pockets or ropes are used to place them on the platform main body 1. The four articulated bolts 13 located in the relatively middle are fastened through the bundle, and the materials that need to be protected are placed in the middle of the platform main body 1, and the four articulated bolts 13 are used for threading and tightening. In this way, during the airborne process During the landing, the centrifugal force generated when tilting and violent shaking can be relatively reduced, which can protect the materials to a certain extent. It can play a certain buffering role, so that the entire airborne platform will not be easily damaged by impact, and the number of repeated use can be increased. Compensation for height automatic adjustment is performed within a certain range of road surface unevenness, so that the traction and transportation are relatively stable. The specific principle is: the left dovetail groove and the right dovetail groove in the device main body 421 cooperate with the first rack 422 and the second The rack 423 meshes with the gear 424 together. The first rack 422 and the second rack 423 are respectively connected to a pair of rollers through the universal bearing 45. The main body 421 of the vertical shaft 413 slides down together. At the same time, because the roller on the side that first contacts the ground has an upward reaction force, the gear 424 connected to the vertical shaft 413 is forced to turn towards the roller on the side that does not touch the ground, so as to Balance the force in two directions. At this time, through the relationship of gear meshing, the rack above the roller that does not touch the ground is urged to slide down until the roller on the other side also touches the ground and the vertical force on both sides is balanced. However, the range of compensation that can usually be adjusted has limitations. In the case of poor relative flatness of the ground, it can still only be transported by force on a single roller.
