Abstract

The utility model relates to a multifunctional airport pavement single-wheel test loading frame. It includes vertical loading basket, limit frame, laser displacement sensor, wheel vertical transmission system and loading weight; wheel vertical transmission system includes main transmission bearing rod, flange bushing, shock absorbing spring, aircraft tire fixing Frame, set screw sleeve and aircraft tire body. The effect of the invention is that the actual aircraft tires are used for loading, which is consistent with engineering practice, has multi-functionality, and can meet the requirements of different road surface tests. When the loading weight is placed in the vertical loading basket, and the vertical transmission system of the wheel and the vertical loading basket are lifted, the vertical loading test of the airport pavement can be carried out, and the wheel print size of different pavements can be studied at the same time; when the limit The frame is fixed on the ground through anchor bolts, and the horizontal force of the main body of the aircraft tire can be experimentally analyzed, such as the influence of the arresting system; when the limit frame is lifted, the main body of the aircraft tire can be used as the tire of the equipment at this time, which is convenient for the equipment. move.

Description

technical field [0001] The invention belongs to the technical field of airport engineering, in particular to a multifunctional airport pavement single-wheel test loading frame. Background technique [0002] Civil aviation is an important part of the national transportation system and is developing rapidly. In 2018, my country's civil aviation completed a total transportation turnover of 120.64 billion ton-kilometers, an increase of 11.4% year-on-year, and a passenger transport volume of 610 million person-times, an increase of 10.9% year-on-year. It is estimated that by 2035, the number of civil aviation airports in my country is expected to increase from 235 in 2018 to about 460. In the future, my country's airport construction will face rapid development. [0003] In the process of airport construction, the airstrip plays an important role as the main passage for aircraft to take off and land. Ensuring the durability and carrying capacity of the runway is an important par...
