Description

Adjustable bearing and supporting device applied to vehicle-mounted parking apron Technical Field The utility model belongs to the technical field of vehicle-mounted parking apron, and relates to an adjustable bearing and supporting device applied to a vehicle-mounted parking apron. Background With the development of aviation technology, the vehicle-mounted parking apron is widely applied in the fields of emergency rescue, special operation and the like. In the use process of the vehicle-mounted parking apron, the stability and the safety of the parking apron are directly influenced by the performance of the supporting device. The existing vehicle-mounted parking apron supporting device has a plurality of problems. On the one hand, in the process of getting on or off the vehicle transportation parking apron, the ground clearance of the parking apron is difficult to flexibly adjust, so that the getting on or off process is unstable, and the parking apron and related equipment are easily damaged. On the other hand, after the parking apron lands, an effective leveling mechanism is lacking, and the upper surface of the parking apron is difficult to reach a horizontal state, so that potential safety hazards exist for taking off and landing of aircrafts such as helicopters. In addition, the existing supporting device has the defects in the aspects of supporting strength and firmness, particularly for the middle suspended position of the parking apron, an effective auxiliary supporting structure is lacking, and accidents are easy to occur due to unstable supporting when the aircraft takes off and land. Meanwhile, when in vehicle-mounted transportation, the supporting device cannot be contained well, the occupied space is large, and the convenience of using and transporting other functions of the vehicle is affected. Therefore, there is an urgent need to design an adjustable bearing and supporting device applied to a vehicle-mounted parking apron, which can overcome the defects. In order to overcome the defects of the prior art, various solutions are continuously explored, for example, a vehicle-mounted parking apron is disclosed in China patent publication [ application number: 20162015417.
