Description
Technical Field
The utility model relates to an equipment airborne buffer especially relates to a heavy equipment airborne buffer.
Background
Along with the service of domestic large-scale transport machines, the carrying capacity of the equipment is greatly improved, but the air-drop capacity of the equipment is limited to a certain extent, and because the equipment mainly depends on the parachute for buffering during air-drop, and the buffering capacity of the parachute has an upper limit, if the air-drop buffering of the assembly is carried out only by the parachute, the assembly air-drop requirement with the self weight of less than 10 tons can only be met.
Therefore, in order to improve the air-drop capacity of equipment, the relevant units develop an air-drop cushion with a steel plate-paper honeycomb structure, and the air-drop cushion can be matched with a parachute to be used, so that the assembly air-drop capacity can be improved to be below 15 tons, but for heavy equipment with the self weight of about 20 tons, the existing air-drop cushion with the steel plate-paper honeycomb structure cannot meet the air-drop requirement.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a heavy equipment airborne crash pad can satisfy the airborne needs that the dead weight is the heavy assembly about 20 tons, and impact force when can the heavy assembly of effective absorption falls to the ground has guaranteed the airborne security of heavy equipment.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an airborne cushion pad of heavy equipment comprises an upper panel, a middle energy absorption column and a lower panel, wherein the upper panel and the lower panel are identical in structure and both adopt aluminum plates and foamed aluminum composite plates; the middle energy-absorbing column is a composite energy-absorbing column of aluminum pipes and foamed aluminum and is vertically arranged; the upper panel, the middle energy-absorbing column and the lower panel are of a stacked composite structure from top to bottom.
The upper panel and the middle energy-absorbing column, and the middle energy-absorbing column and the lower panel are bonded together by silicone adhesive or welded together by spot welding.
The number of the middle energy-absorbing columns is a plurality, the middle energy-absorbing columns are arranged in a vertical distribution mode, and the adjacent middle energy-absorbing columns are bonded together by silicone adhesive or welded together by spot welding.
The upper panel is 5-30 mm thick, the height of the middle energy-absorbing column is 100-600 mm, the diameter of the middle energy-absorbing column is phi 50-100 mm, and the lower panel is 5-30 mm thick.
