Description

Technical Field

[0001] This utility model relates to the field of aircraft ground maintenance technology, and in particular to a support tool for opening the water service cover of an Airbus A330. Background Technology

[0002] With the continuous growth in flight volume, the Airbus A330 is being used more frequently on domestic and international routes, leading to a significant increase in the demand for supporting maintenance tools. During the execution of two work card tasks—"Disinfecting the Drinking Water System (PWS) with Hypochlorite and Replacing the Water Filter Cartridge (if Installed)" and "Disinfecting the Drinking Water System (PWS) with Hydrogen Peroxide (H2O2)"—specialized support tools are required to keep the water service cover in the open position. Because this is field work, strong winds can sometimes blow the cover away, making it difficult to maintain stability during opening and operation. However, currently used specialized support tools generally have the following problems:

[0003] First, most existing specialized support tools are made with PVC shells. Although the processing technology is mature, the material strength is insufficient, making them prone to damage under frequent operation and external forces. Furthermore, PVC is still prone to cracking and deformation under prolonged use and changes in ambient temperature, ultimately rendering the tools unusable. Due to the high frequency of routine maintenance for the A330 model, the lifespan of these tools is generally short, forcing maintenance departments to replace them frequently.

[0004] Secondly, the procurement cost of existing specialized support tools is high, especially since some models are still monopolized by foreign manufacturers. Constrained by import channels and pricing, overall costs remain high. Coupled with the high rate of tool wear and tear, this not only increases the economic burden on operating units but also restricts the efficiency of tool support.

[0005] In summary, existing technologies cannot simultaneously meet the requirements of low cost, durability, and independent control. Maintenance units still face the dilemma of rapid tool wear and tear, high procurement costs, foreign monopoly, and significant economic losses when ensuring daily work tasks.

[0006] Therefore, it is necessary to propose a new solution and develop a water service cover opening support tool that can meet the requirements of the A330 water service operation card, reduce costs, improve durability, and achieve domestic substitution. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an Airbus A330 water service cover opening support tool to overcome the deficiencies in existing technologies.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A support tool for opening the water service cover of an Airbus A330 includes a cover end clamp, a telescopic assembly, and a water service end clamp. The cover end clamp and the telescopic assembly are connected by a first spherical hinge, and the telescopic assembly and the water service end clamp are connected by a second spherical hinge. This allows the cover end clamp to clamp the cover of the aircraft's water service at a suitable angle, and also allows the water service end clamp to fit onto the original locking pin on the inner side of the aircraft's water service at a suitable angle. The telescopic assembly has an adjustable telescopic length, allowing the support tool to adapt to supporting the opening of the water service cover to the required angle.

[0010] The cover plate end clamp includes a cover plate end cylinder and a cover plate end knob; the cover plate end cylinder is connected to a first spherical hinge and forms a gap between the cover plate end cylinder and the first spherical hinge, the gap being used to clamp the cover plate of the water service; rotating the cover plate end knob can adjust the width of the gap between the cover plate end cylinder and the first spherical hinge.

[0011] Furthermore, the water service terminal clamp includes a base, with a first limiting plate and a second limiting plate respectively erected on both sides of the base, making the water service terminal clamp as a whole concave shape.

[0012] Furthermore, a locking block is also provided on the base, which is located between the first limiting plate and the second limiting plate, and the locking block is screwed into the water service end knob.

[0013] Furthermore, the telescopic assembly includes a telescopic bearing and a first sleeve and a second sleeve respectively fitted onto both ends of the telescopic bearing. The first sleeve is connected to a first spherical hinge, and the second sleeve is connected to a second spherical hinge.

[0014] Furthermore, both the first sleeve and the second sleeve are provided with fixing bolts that penetrate laterally into the cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1) The Airbus A330 water service cover opening support tool in this case is manufactured using 3D printing technology, resulting in low manufacturing costs and rapid replenishment, allowing for quick printing and deployment. The PLA material has sufficient strength for daily use, and the tool's modular structure facilitates component replacement, avoiding complete scrapping, reducing maintenance costs, and minimizing economic losses. Furthermore, this tool achieves domestic substitution, avoiding dependence on foreign products and contributing to ensuring independent control over aircraft maintenance work.

[0017] 2) The Airbus A330 water service cover opening support tool in this case is provided with a first spherical hinge and a second spherical hinge between the cover end clamp, the telescopic component and the water service end clamp, respectively, so that the angle of the cover end clamp and the water service end clamp is adjustable, which is more suitable for stably supporting the water service cover to open to a suitable angle, and facilitating the maintenance operation of the water service.

[0018] 3) The Airbus A330 water service cover opening support tool in this case has a telescopic component between the cover end clamp and the water service end clamp, which can flexibly adjust the overall length of the tool to further stabilize and support the water service cover to open to a suitable angle.

The telescopic bearing (21) can be adjusted and locked in the first sleeve (22) and the second sleeve (23) by fixing bolts (24), thereby adjusting the overall length of the telescopic assembly (2) to adapt to the size of the cover opening angle and meet the operating space requirements under various conditions.

[0031] The water service end clamp (3) includes a base (31), on which a first limiting plate (32) and a second limiting plate (33) are respectively erected on opposite sides, making the water service end clamp (3) concave in shape. A locking block (34) is also provided on the base (31), which is located between the first limiting plate (32) and the second limiting plate (33). The water service end clamp (3) is used to connect to and fit into the original locking pin on the inner side of the aircraft water service end. Through the cooperation and limiting of the locking block (34), the water service end knob (35), the first limiting plate (32) and the second limiting plate (33), the water service end clamp (3) is locked on the locking pin, thereby forming a stable fulcrum.

[0032] As a preferred option, the support tools in this case can be manufactured entirely or in parts using PLA (polylactic acid) consumables through 3D printing technology. The components are assembled through a modular structure, which facilitates quick replacement and maintenance.
