Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, a detection device flush with the ground is designed, which can conveniently tow the aircraft to the upper surface of the front wheel turntable 3. The front wheel turntable 3 meets the technical requirements for parking the aircraft, and avoids the need to push the aircraft when the nose wheel turning function inspection is performed. Complicated and complicated work steps; its surface is equipped with an adjustable locking device 4 for fixing the front wheel of the aircraft. Relative movement occurs between the front wheel and the front wheel turntable 3, resulting in measurement errors; there is an adjustable ring-shaped high-precision angle indicator 2 outside the front wheel turntable 3, which is convenient for the aircraft to enter from any angle and quickly adjust the measurement angle. Large, so the measurement accuracy can be improved, and the measured angle can be accurately and clearly reflected; it has a zero point ca...

Abstract

The invention relates to a device for performing front-wheel turning function inspection without jacking an aircraft. The device comprises a laser calibration device (1), an angle indicator (2), a front-wheel rotating disc (3) and a locking device (4); the device is characterized in that the front-wheel rotating disc (3) is a body part of the device for performing front-wheel turning function inspection without jacking the aircraft, and the annular angle indicator (2) and the laser calibration device (1) are arranged on the outer side periphery of the front-wheel rotating disc (3) as measuringparts; the locking device (4) is arranged on the front-wheel rotating disc (3) as an auxiliary part. Under the condition of not jacking the aircraft, the aircraft front-wheel turning function is inspected, workers are greatly reduced, the working procedure of jacking the aircraft is omitted, and the condition requirement for using tools is reduced; the workers can be effectively reduced, the production efficiency is improved, the technological threshold is lowered, economic benefits are improved, and abrasion to the aircraft and the tools is reduced.

Description

technical field [0001] The patent of the invention belongs to the field of aviation industry, and relates to a device and method for checking the steering function of front wheels in aircraft manufacturing and maintenance. Background technique [0002] In the aviation field, during the manufacture and maintenance of aircraft, it is necessary to perform functional inspections on the nose turn system of the landing gear to ensure that the aircraft can perform functions such as low-speed and large-angle turns on the ground, small-angle corrections at high speeds on the ground, front wheel swing reduction, and turn release. Realize; at present, the function inspection of the nose turn system of the aircraft landing gear is generally carried out by using a jack to jack up the aircraft in situ; since this method needs to consider the factors of the wheel load signal, the jack is directly connected to the landing gear. The method of contacting and jacking up; under the condition of...
