A Height Platform Adjustment Device Applied to Assembly of Fuel Main Pipe and Its Application Method

Abstract

The invention provides a height platform adjusting device applied to the assembly of a fuel oil main pipe and a using method of the height platform adjusting device, and belongs to the technical fieldof assembly of aviation parts. The height platform adjusting device applied to the fuel oil main pipe assembly comprises a round base, a positioning ring, positioning pins, an angular positioning device and a height adjusting device, wherein the positioning ring is arranged on the round base, and a plurality of positioning pins are arranged on the positioning ring in the circumferential direction. The round base is provided with a first extending end and a plurality of second extending ends, the angular positioning device is arranged on the first extending end, and each second extending end is provided with a height adjusting device. Each angular positioning device comprises a positioning support, an angle plate, a first threaded rod, a first nut and a threaded sleeve. Each height adjusting device comprises a base plate, a guide seat, a wedge block, a sliding column, a dowel, a spring, a support plate, a second threaded rod, a second nut, a third threaded rod, a third nut and a handle. According to the device, the assembly of the fuel oil main pipe can be realized, the operation difficulty is lowered, a main combustion chamber is not required to be hoisted, and the safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of assembly of aviation parts, in particular to a height platform adjustment device and a use method applied to the assembly of a fuel main pipe. Background technique [0002] During the assembly process of the fuel pipeline of the main combustion chamber, due to the complicated external pipelines and strict requirements on the height of the casing of the main combustion chamber, the traditional assembly usually adopts hoisting of the casing of the main combustion chamber, and the lug of the fuel main pipe is installed on the main combustion chamber. In the ear seat of the combustion chamber casing, align and connect the multiple fuel injection pipes on the fuel manifold with the nozzles of the main combustion chamber casing. Continuously adjust the installation position, and lock it after adjusting to the required position. During the adjustment process, the main combustion chamber casing is hoisted, with l...

[0002] During the assembly process of the fuel pipeline of the main combustion chamber, due to the complicated external pipelines and strict requirements on the height of the casing of the main combustion chamber, the traditional assembly usually adopts hoisting of the casing of the main combustion chamber, and the lug of the fuel main pipe is installed on the main combustion chamber. In the ear seat of the combustion chamber casing, align and connect the multiple fuel injection pipes on the fuel manifold with the nozzles of the main combustion chamber casing. Continuously adjust the installation position, and lock it after adjusting to the required position. During the adjustment process, the main combustion chamber casing is hoisted, with large disturbance, difficult operation and low work efficiency, and hoisting the main combustion chamber casing The risk factor is high, which makes the main combustion chamber fuel pipeline assembly a safety hazard
