Electric wheel chock capable of automatically collecting time of wheel chock

Abstract

The invention discloses an electric wheel chock capable of automatically collecting wheel chock time. The wheel chock comprises a wheel chock body, a control system, trundles and a deicing fluid release device, the wheel chock body is a hollow triangular prism, and anti-skid rubber strips are arranged on the surfaces of the front baffle and the rear baffle. The control system comprises a stress sensor, an RFID signal transceiver, a controller, a motor, a power supply and an electric control valve; the deicing liquid releasing device comprises a liquid storage tank, a liquid discharging pipeline and a spray head. The anti-skid electric wheel chock has the advantages that the anti-skid rubber strip can be tightly attached to an airplane wheel after the electric wheel chock is stressed, and stress is scientific and reasonable; the recorded wheel chock time is more accurate through the full-automatic wheel chock loading and unloading process, and deviation caused by manual recording is avoided; the stress sensor can enable the blocking of the electric wheel chock to the airplane wheel to reach a proper threshold value, and is safe and controllable; in ice and snow weather, the electric wheel chock can release the deicing fluid to remove accumulated snow on the road surface during operation, so that the labor intensity of maintenance personnel can be reduced, the task response time can be effectively shortened, and the airport flight guarantee operation efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft ground equipment, in particular to an electric wheel block capable of automatically collecting wheel block time Background technique [0002] Under normal circumstances, when the aircraft is parked, flight support and maintenance operations, it is necessary to place wheel chocks before and after the wheels of the aircraft to prevent the aircraft from moving, thereby affecting maintenance operations or causing damage due to aircraft movement. The traditional aircraft wheel block has a limited blocking force and can only be used when the aircraft is parked, which is easy to damage the ground and difficult to take out. Moreover, because the maintenance personnel need to manually place it, there may be leakage, late blocking, and unblocking of the wheel block. , resulting in a safety hazard, and the use of traditional wheel blocks in ice and snow conditions is limited. With the changes in the mainte...

AI Technical Summary

Problems solved by technology

[0004] 1) The blocking effect is not good, and it is not suitable for blocking when the aircraft is sliding;

[0005] 2) After use, it is easy to be squeezed between the aircraft and the ground. During the removal process, the wheel chock is easily ejected due to force, which brings danger to the staff

[0006] 3) Manually placing wheel chocks is not only inefficient, but also manual reporting of wheel chock time will cause certain deviations

[0007] 4) When encountering ice and snow weather, the airport ground is icy and affects the normal use of wheel chocks
