Abstract

The invention relates to the technical field of general aviation, and discloses carrying equipment for moving a skid helicopter on ground. The carrying equipment comprises a head mechanism and a framemechanism. The head mechanism comprises a cabin; a storage battery, a motor drive wheel, a hydraulic system and a control system module are mounted in the cabin, and the storage battery provides power to the motor drive wheel, the hydraulic system and the control system module. The frame mechanism comprises cross beams; a clamping structure is mounted on the cross beams and used for assembling askid undercarriage. The hydraulic system is connected with front hydraulic cylinders and back hydraulic cylinders, the rear end of the cabin is connected with the front end of each cross beam throughone link mechanism and one front hydraulic cylinder, and the link mechanism and the front hydraulic cylinder controls the corresponding cross beam to move vertically relative to the cabin; the rear end of each cross beam is connected with a back brace through the other link mechanism and one back hydraulic cylinder, the link mechanism and the back hydraulic cylinder controls the corresponding cross beam to move vertically relative to the back brace, and rollers are mounted in the back brace. The carrying equipment has stable and reasonable structure, the process of assembling the carrying equipment with the undercarriage of the helicopter is facilitated and accelerated, labor intensity is reduced, efficiency is improved, and safety and reliability in carrying are both guaranteed.

Description

technical field [0001] The invention relates to the technical field of general aviation, in particular to a handling device for sled helicopter ground movement. Background technique [0002] Since R66, AS350 and AC311 helicopters use sled landing gear and cannot taxi on the ground, they need other auxiliary devices to move between aprons or between aprons and hangars and maintenance workshops. There are two traditional handling methods. One is suitable for light and small helicopters. It is necessary to install a ground wheel on the landing gear on the left and right sides of the helicopter, and then one person presses down on the tail of the aircraft to use the ground wheel as a fulcrum to lift the helicopter off the ground. , and then two other people need to stand on both sides of the helicopter and push forward to move the helicopter; the other is suitable for helicopters with larger masses. Linked, the helicopter is moved by the tractor. The traditional handling metho...
