Description

Technical Field

[0001] The invention belongs to the field of aircraft modification, and in particular relates to 800vu disassembly and assembly equipment on an aircraft. Background Art

[0002] During the conversion of passenger-to-freighter (PTF) aircraft (such as A330), the refueling / extraction control panel (800VU) on the aircraft needs to be disassembled and assembled. Currently, there is no suitable equipment for this work, and it can only be disassembled and assembled by manpower. Due to the heavy weight of 800VU, the steps at the installation site, and the small upper and lower space, it is difficult to disassemble and assemble. Manual disassembly and assembly takes a long time, and there are also risks such as damage to equipment and personnel safety.

[0003] Chinese patent application No. 2017108691158 discloses a safe working method for a displacement robot arm, comprising the following steps: rotating the transport spindle by holding one end of the transport handle, and rotating the transport clamping device by holding the other end of the transport handle; moving the transport clamping device to the pre-transported workpiece position in combination with the previous step by controlling the extension and retraction of the bracket and the transport spindle; the opening and closing drive system is operated, and a pair of clamping arms of the transport clamping device drives a pair of suction cups to close and clamp the workpiece; the grasping drive system is operated, and a pair of suction cups fix the workpiece by suction; the workpiece is transported to the desired position by controlling the extension and retraction of the bracket and the transport spindle, and the rotation of the transport spindle and the transport clamping device; the grasping drive system stops running, and a pair of suction cups are released and detached from the workpiece; a pair of suction cups continue to open to a set position; the present invention improves production efficiency and is simple to operate. It can only be rotated when the transport handle is held tightly to prevent misoperation and has a high safety factor. Summary of the invention

[0004] The main purpose of the invention is to provide an 800vu disassembly and assembly device, which can easily and conveniently disassemble and install the 800vu from an aircraft.

[0005] The purpose of the present invention is achieved through the following scheme: an 800vu disassembly and assembly device, fixed on a forklift board, the front end of which is used to fix a refueling / pumping control panel (800VU), comprising a lifting frame assembly, a flip frame assembly and a flip mechanism assembly, wherein: The lifting frame assembly includes a lifting frame, which is composed of two upper and lower fulcrum cross bars and four support bars symmetrically arranged on the left and right between the fulcrum cross bars. The left and right ends of the fulcrum cross bars are fixed with angle fulcrums matching the connection points of the oil filling / pumping control panel (800VU), at least one pair of sliders are fixed to the rear sides of the two outer slider support bars, and lifting nuts are fixed to the middle of the rear sides of the two inner lifting support bars; The flip frame assembly includes a flip frame, which is composed of two left and right guide rail vertical rods and two upper and lower cross bars between the guide rail vertical rods. A guide rail is fixed on the outer side of the guide rail vertical rod, and a lifting motor with a screw is fixed in the middle of the lower cross bar. The slider is fixed in the guide rail, and the lifting nut is sleeved on the screw, so that the lifting frame assembly can move up and down relative to the flip frame assembly. The flipping mechanism assembly comprises a flipping link, a swing arm link, a telescopic link with a telescopic motor and a rectangular bottom frame which are symmetrical on both sides. The rear end of the flipping link, the top of the swing arm link and the front end of the telescopic link are hinged together. The front end of the flipping link is hinged to the middle inner side of the guide rail vertical rod, the bottom inner side of the guide rail vertical rod is hinged to the two sides of the front end of the rectangular bottom frame, the bottom end of the swing arm link is hinged to the two sides of the front part of the rectangular bottom frame so that the guide rail vertical rod is parallel to the swing arm link, the telescopic motor is fixed to the two sides of the rear end of the square bottom frame, and the rectangular bottom frame is fixed to the forklift plate. When the telescopic link is extended, it drives the flipping frame assembly to flip forward together with the swing arm link, and when the telescopic link is retracted, it drives the flipping frame assembly to flip backward together with the swing arm link.

[0006] Based on the above scheme, the corner fulcrum includes a corner fulcrum mounting plate, a support rod and a push rod clamp fixed at the end of the fulcrum cross bar, the support rod of the upper corner fulcrum on the upper fulcrum cross bar is installed on the top edge of the corner fulcrum mounting plate, the push rod clamp of the upper corner fulcrum is installed on the rear side of the corner fulcrum mounting plate, the support rod of the lower corner fulcrum on the lower fulcrum cross bar is installed on the front side of the corner fulcrum mounting plate, and the push rod clamp of the lower corner fulcrum is installed on the top edge of the corner fulcrum mounting plate.

The refueling / pumping control panel (800VU) is fixed to the front side of the lifting frame assembly through the corner support and the upper middle support. The lifting motor rotates to control the vertical movement of the lifting frame assembly to avoid the steps at the installation location. The telescopic motor controls the flip frame assembly to flip backwards to reduce the upper and lower space required for transportation.

[0010] The advantages of the present invention are: simple structure, easy operation, and can be used in the narrow space of the cabin, which effectively saves manpower and time costs and well avoids the risks of equipment damage and personal injury. BRIEF DESCRIPTION OF THE DRAWINGS
