Description

Technical Field

[0001] This utility model relates to the field of aircraft ground maintenance technology, and in particular to an auxiliary tool for installing aircraft slide packs. Background Technology

[0002] Airplane slide packs are emergency life-saving devices on aircraft, primarily used to evacuate passengers and crew in emergencies to minimize injury. Each cabin door of a passenger aircraft has an airplane slide pack containing a folded emergency slide. The Airbus A330's slide pack weighs 50 kg and measures 105 cm in length, 37 cm in width, and 45 cm in height. The bottom of the slide is 4 cm off the ground. There are no pre-designed handholds on the slide pack; due to the confined space, installation requires two people to support the bottom of the slide pack, raising it to approximately 6 cm. The slide is then aligned, and the U-shaped hook is attached to the boarding door hook. Finally, the slide is lowered back to its original 4 cm position. Because of the confined space and heavy weight of the slide pack, installation can easily result in hand or back injuries. Currently, there are no dedicated installation tools available domestically or internationally. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an auxiliary tool for installing aircraft slide packs to overcome the deficiencies in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An auxiliary tool for installing an aircraft slide package includes a tray, a bracket, and wheels.

[0006] The tray is a square frame with straight slots on the side panels of the frame on both sides.

[0007] The bracket includes an L-shaped handrail and a bracket side plate. The bracket side plate is integrally fixed at the bend of the L-shaped handrail and located on both sides of the L-shaped handrail. The bracket side plate is connected to the tray through a first double hinge plate.

[0008] The front end of the bracket side plate is provided with a third shaft pin, which is slidably connected to the straight groove of the tray.

[0009] The traveling wheels include rear wheels and front wheels.

[0010] Furthermore, the front wheel is rotatably mounted on the front of the pallet via an axle bracket; one end of the second double hinge plate is rotatably connected to the axle of the front wheel, and the other end of the second double hinge plate is connected to the third axle pin on the bracket side plate, so that when the third axle pin slides in the straight groove of the pallet, the bracket side plate, the first double hinge plate, and the second double hinge plate are also linked together.

[0011] Furthermore, one end of the first double-hinged plate is rotatably connected to the bracket side plate via a first pivot pin, and the other end of the first double-hinged plate is rotatably connected to the tray via a second pivot pin.

[0012] Preferably, the tray, the second double hinge plate, and the front wheel axle frame form a triangular structure.
