Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] see Figure 1 to Figure 4 , a lifting device for large passenger aircraft mobile production line transfer equipment, including lifting front bracket 1, lifting frame 2, connecting shafts 3, 13, commutator 4, coupling 6, double output shaft motor 7, Elevator 9, sliding auxiliary guide rail 10 and slide block 11.

[0021] The front end of the lift frame 2 is open, and two supporting plates 23 protrude from the two side wings of the upper end. Rotate to enclose and affix the lift frame 2, which is locked and affixed by pin 12 to form an integral lift support bracket. The inner surface of the front bracket 1 and the inner surface of the rear end crossbeam of the lifting frame 2 are arc-shaped, and the two arc-shaped bottoms protrude forward, which is convenient for the front wheel of the front landing gear of the aircraft to be supported. ...

Abstract

The invention discloses a holding and lifting device of large-scale passenger airplane mobile production line shifting equipment. The front end of a holding and lifting frame (2) is open; a holding and lifting front bracket (1) and the holding and lifting frame are hinged through a pin shaft (8); the holding and lifting front bracket rotates around the pin shaft to surround the fixedly connect the holding and lifting frame; the inner surface of the holding and lifting front bracket and the inner surface of a transverse beam (21) at the rear end of the holding and lifting frame are arc-shaped; the bottoms of the two arc shapes extend forwards; the top of a lifting machine (9) is arranged and fixed on the lower surface of wing supporting plates (23) on two sides of the upper end part of the holding and lifting frame; each of output shafts at two ends of a double output shaft motor is connected with the lifting machine (9) sequentially through a shaft coupler (6), a connecting shaft (13), a commutator (4) and a connecting shaft (3); the holding and lifting frame can move up and down under the jacking action of the lifting machine; left and right groups of sliding secondary sliding blocks (11) are arranged on the outer back side of the transverse beam at the rear end of the holding and lifting frame; two sliding secondary guide rails (10) are arranged and fixed on the frame of the shifting equipment (5); and the holding and lifting frame can move up and down along with the guide rails.

Description

technical field [0001] The invention relates to a transfer device for a mobile production line of a large passenger aircraft, in particular to a lifting device for a traction device for a mobile production line of a large passenger aircraft. Background technique [0002] The transfer equipment of the large passenger aircraft mobile production line includes production line traction equipment and aircraft carrying equipment. The lifting device belongs to the subsystem of the large passenger aircraft mobile production line traction equipment. provide assurance. The existing lifting device mainly includes a wheel holding mechanism and a lifting mechanism. The lifting mechanism adopts a rotary structure to make the front landing gear rotate up and down around a point, and the lifting device is controlled by a complex hydraulic system. When the wheel holding bracket and the front bracket close the front wheels of the aircraft in the wheel holding mechanism under the control o...
