Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for aircraft maintenance, in particular to a protective pad for aircraft maintenance work. Background Art

[0002] In recent years, more and more types of aircraft have appeared in my country, and the frequency of use of military aircraft has also increased. With the continuous development and research of my country's military aircraft, its main maintenance technical means are changing components. In the future, military fighter jets and other military aircraft will be safer, more reliable, more flexible and easier to deploy and maintain.

[0003] With the continuous development of social economy, the development level of my country's transportation industry has been significantly improved. As an important part of my country's transportation system, civil aviation has received more and more attention from all walks of life. With the continuous increase in business, some faults will occur during the operation of the aircraft, which will directly affect the safety of the aircraft. Therefore, improving the quality and efficiency of maintenance is very necessary to protect the flight safety of civil aviation aircraft.

[0004] As aircraft fly more and more frequently, the aircraft themselves are getting older, malfunctions occur more and more frequently, and maintenance is required more and more frequently. When maintenance personnel board the wings and fuselage of the aircraft, the surface of the aircraft is too smooth and they can easily slip and get injured. In addition, the stealth coating on the surface of the aircraft can be easily scratched off, and if there is dirt on the soles of shoes, it can easily get on the surface of the aircraft, making the aircraft more prone to rust. For this reason, anti-slip mats are now laid on the surface of the aircraft to avoid slipping and injuries and to prevent maintenance personnel from bringing dirt to damage the aircraft surface.

[0005] However, when the anti-skid mat is directly laid on the surface of the aircraft, the maintenance personnel may fall when walking on the anti-skid mat due to the poor connection between the anti-skid mat and the aircraft. In order to solve this problem, a protective mat for aircraft maintenance work is proposed. Utility Model Content

[0006] In response to the above technical problems, the utility model provides a protective mat for aircraft maintenance work. The protective mat laid on the aircraft surface is designed to be divided into two layers, the lower layer is a fixed mat for connecting to the aircraft surface, and the upper layer is an anti-skid non-slip mat. Suction cups and anti-skid rubber strips are arranged at intervals under the fixed mat, so that the suction cups under the fixed mat are sucked onto the aircraft surface, thereby enhancing the stability of the connection between the protective mat and the aircraft surface.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A protective mat for aircraft maintenance work, characterized by comprising a fixed mat, an anti-skid mat, an anti-skid rubber strip suction cup, and a warning component. The fixed mat has a cavity structure, a plurality of suction cups and anti-skid rubber strips are arranged at intervals below the fixed mat, an air outlet on the top of the suction cup is connected to the inner cavity of the fixed mat, an anti-skid mat is arranged above the fixed mat, and a warning component is installed on one side of the fixed mat.

[0009] The air extraction hole provided on one side of the fixed pad is connected to the air extraction connecting pipe, a one-way valve is provided on the air extraction connecting pipe, and the air extraction hole of the fixed pad is connected to the inner cavity of the fixed pad.

[0010] The warning assembly consists of a fixed seat, a rotating shaft, a limiting part, a connecting block, a mounting rod and a warning flag. The fixed seat is fixedly connected to the fixed pad. The rotating shaft is installed on the bearing of the fixed seat. The upper end of the rotating shaft is connected to the fixed seat through the limiting part. The rotating shaft is connected to the connecting block. The connecting block is connected to the mounting rod. A warning flag is provided on the mounting rod.

[0011] The limiting portion includes a protruding plate and a limiting stud. The protruding plate is fixedly connected to the rotating shaft. A limiting hole is provided on the protruding plate. The limiting stud passes through the limiting hole on the protruding plate and is threadedly connected to a threaded hole provided on the fixing seat.

[0012] Specifically, the anti-slip pad is provided with anti-slip convex patterns.

[0013] Specifically, the anti-slip rubber strip is on the same horizontal line as the suction cup.

[0014] Beneficial effects of the utility model:

[0015] The utility model designs the protective pad laid on the aircraft surface into two layers, the lower layer is a fixed pad for connecting to the aircraft surface, and the upper layer is a non-slip non-slip pad. Suction cups and non-slip rubber strips are arranged at intervals below the fixed pad. After the protection point is laid on the aircraft surface, air is extracted by connecting the air extraction device to the air extraction connecting pipe on the side of the fixed pad, so that the suction cup under the fixed pad is sucked to the aircraft surface, thereby enhancing the stability of the connection between the protective pad and the aircraft surface. A one-way valve is provided on the air extraction connecting pipe to prevent air from being extracted and then entering.

[0016] The utility model provides an installation warning component on one side of the fixed pad. The installation rod for installing the warning flag can adjust its placement angle according to the laying situation. The limiting stud in the limiting part is removed to release the limit of the rotating shaft. After directly rotating the installation rod and adjusting it to the corresponding angle, the limiting stud is inserted from the limiting hole of the protruding plate on one side of the rotating shaft and connected to the corresponding threaded hole on the fixing seat. The position of the installation rod at this time can be fixed, and the warning flag is adjusted to a suitable position for easy observation by staff, preventing maintenance personnel from forgetting to remove the protective pad when the aircraft is dispatched.
