Field disassembly and assembly type helicopter take-off and landing terrace
The utility model discloses a field detachable helicopter take-off and landing terrace, and mainly relates to the technical field of helicopter take-off and landing terraces. Comprising a plurality of main plates, male inclined plates and female inclined plates, wedge-shaped blocks are arranged on one transverse edge and one vertical edge of each main plate and one side of each male inclined plate respectively, wedge-shaped grooves are formed in the other transverse edge and the other vertical edge of each main plate and one side of each female inclined plate respectively, limiting columns are arranged in the wedge-shaped grooves, and grooves in sliding connection with the limiting columns are formed in the wedge-shaped blocks. An elastic block is arranged in the groove, a protrusion is arranged at the end of the elastic block, and the upper side and the lower side of the protrusion are provided with a first inclined face and an arc-shaped face which make contact with the limiting column respectively. The helicopter landing terrace has the advantages that the problem that an existing helicopter landing terrace cannot be disassembled and assembled is solved, the cost of long-time field operation of a helicopter is reduced, and meanwhile the efficiency of laying the helicopter landing terrace is improved.
