Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

As shown in fig. 1 and 2, the structure of the aircraft engine maintenance mobile shed is the structure of the aircraft engine maintenance mobile shed of the present invention. This aircraft engine maintains and removes worker canopy comprises 4 180 arch canvas posts 1, 7 straight

line canvas posts

2, 4 short canvas posts 3, 6 (respectively 3 about each) bottom short canvas posts 4, canvas 5, inflation inlet (two) 6 and can dismantle canvas 7.

The cross points of the arched canvas column 1, the top short canvas column 3, the bottom short canvas column 4 and the linear canvas column 2 are communicated with each other. The canvas 5 is covered between the arch canvas post 1, the top short canvas post 3, the bottom short canvas post 4 and the straight canvas post 2 and under the foremost one arch canvas post. A detachable canvas 7 is arranged between the top short canvas column 3 and the bottom short canvas column 4, and a primary belt and a secondary belt are arranged around the detachable canvas, and can be selectively arranged on the left side or the right side. The bottom positions of two sides of the arched canvas column at the front part of the movable work shed are respectively provided with an inflation inlet 6, and the movable work shed can be inflated and deflated by using an electric pump. The inflation inlet 6 is provided with a one-way valve, and when the inflation is carried out, the front section of the inflation tube jacks up the one-way valve to inflate the air column. After the inflation is finished, the inflation tube is withdrawn, the one-way valve is closed, and the air leakage is prevented. The other opening area is provided with a zipper type door curtain.

When not inflating, the movable work shed can be placed after being folded, and the occupied size is small. After the movable work shed is unfolded and inflated, an arched ceiling can be formed. Because the engine is arranged below the large wing, a notch at the position of the large wing is reserved at the rear end of the movable work shed, and more coverage is provided for the engine area.

The top end of the work shed is provided with a linear canvas column for fixing the upper end according to the mounting point of the aircraft engine and the height of the upper surface of the adjacent large wing. The supporting column can be used for hanging a cloth curtain, and can seal the gap between the engine and the front edge of the large wing at the outer side of the engine after hanging down, so that the defects of air leakage and rain leakage caused by the gap are effectively overcome. The cloth curtain is divided into a left side and a right side, and the situation that the work shed is used on the engines on the left side and the right side is compatible.

Meanwhile, the work shed is provided with a mute mobile generator, and can provide required electric power for an inflator pump, an electric heater, an air conditioner and the like. A115V-220V transformer is arranged, and a power supply on the airplane can be utilized to provide required power for necessary equipment such as an inflator pump. The movable electric heater and the air conditioner are equipped, so that the working environment of workers is effectively improved.

In one embodiment, the arched canvas columns are 0.5 meters in diameter, 4.5 meters in height, 6.5 meters in transverse span, and 1 meter apart.

The diameter of the top short canvas column is 0.5 m, the height is 0.8 m, the transverse span is 4.3 m, and the distance is 0.9 m.

The diameter of the bottom short canvas column is 0.5 meter, the height is 2.1 meters, and the transverse span is 0.8 meter. The spacing was 0.9 meters.

The diameter of the straight canvas column is 0.5 meter, the length is 6.7 meters, and the straight canvas column is uniformly distributed along the arch canvas column.

The size of the movable work shed is suitable for the left and right engines of the 737NG machine type; the upper part is longer than the lower part by a certain size, and the excessive part is positioned at the upper part of the large wing, so that the stability of the work shed can be improved.

The gap of the big wing is provided with detachable canvas. The large wing is swept backward and symmetrical left and right. Therefore, when the left engine uses the movable shed, the canvas on the right side of the movable shed is removed; when the right engine uses the movable work shed, the canvas on the left side of the movable work shed is removed. The air tightness is improved, and the configuration difference of the left side and the right side of the airplane can be considered at the same time.

The transformer of 115V to 220V that is equipped with can utilize the power on the aircraft to provide required electric power for necessary equipment such as pump, is favorable to when other electric power do not satisfy, uses aircraft self electric power to accomplish work such as studio inflation.

The utility model provides an aircraft engine maintains and removes worker canopy, uses and maintains the convenience, and occupation space is little after the folding storage. The invention uses cylindrical canvas as a frame, and a layer of canvas is covered on the frame. Before use, the movable work shed is unfolded, and an inflator pump is used for inflating; after use, the inflator pump is used for reverse deflation and is folded and collected. After the fixed counterweight bag is placed in place, the 7-8-level strong wind can be resisted due to the self gravity and the added fixed counterweight bag (water or sand can be filled in the fixed counterweight bag), and the outer sides of the left bottom and the right bottom of the shed are respectively provided with four hanging rings for installing the fixed counterweight bag. The protection of keeping out the wind and keeping out the rain is provided for the maintenance work of the engine, and the related maintenance work of the engine can be smoothly executed.
