An auxiliary tool for removing the cover plate of the aircraft fuel tank

Abstract

An auxiliary tool for removing the fuel tank cover of an aircraft. The whole tool is fixed on the fuel tank cover after the bolt passes through the sleeve. At this time, the cutting head is perpendicular to the fuel tank cover, and the entire tooling can be adjusted by adjusting the length of the sleeve. The distance between the tooling and the fuel tank cover drives the power box so that it slides in the circumferential direction along the outer slide rail and the inner slide rail through the slider Ⅰ and slider Ⅱ, so that the position of the cutter head is adjusted in the circumferential direction, and then Drive the power box to slide laterally along the guide rail block, so that the unscrewing head moves to the same axis as the fuel tank screw to be removed, and the power mechanism drives the unscrewing head to rotate, so as to complete the rotation of the corresponding fuel tank screw, so that it can be removed from the fuel tank cover. tear down. Since the power box is moving, the cutter head is always perpendicular to the fuel tank cover, which not only improves the efficiency of fuel tank screw removal, but also effectively prevents the phenomenon of screw dismantling and improves the convenience of removal.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance tools, in particular to an auxiliary tool for removing an aircraft fuel tank cover. Background technique [0002] The aircraft fuel tank cover is distributed under the wing of the aircraft, which is used to check the internal structure of the aircraft fuel tank and general service use. The ground is high, and it is necessary to exert upward force when removing with the help of auxiliary facilities such as ladder frames, and because the installation torque of the fixing screws is relatively large, the staff cannot work for a long time under the condition of continuous force. 2. Due to the large installation torque of the fixing screws, when using the existing auxiliary force tool "nail remover" to remove the position, it is necessary to frequently change the fixed position of the "nail remover" according to the position of the removed fixing screw.

AI Technical Summary

Problems solved by technology

[0002] The aircraft fuel tank cover is distributed under the wing of the aircraft, which is used to check the internal structure of the aircraft fuel tank and general service use. The ground is high, and it is necessary to use upward force when removing auxiliary facilities such as ladder frames, and because the installation torque of the fixing screws is relatively large, the staff cannot work for a long time under the condition of continuous force

2. Due to the large installation torque of the fixing screws, when using the existing auxiliary force tool "nail remover" to remove the position, it is necessary to frequently change the fixed position of the "nail remover" according to the position of the removed fixing screw. Each aircraft has 20 Left and right fuel tank cover, so wasting a lot of working time and reducing work efficiency

3. In theory, one person is required to complete the demolition work, but because another worker is needed to assist in using the "staple remover", this will increase manpower and reduce work efficiency

4. When using the removal tool to remove the fixing screw, it is necessary to remove the removal tool and the screw to achieve the maximum removal effect. Since the staff needs to work upwards, it is difficult to ensure the vertical effect, and then the screw "removal flowers", further increasing the difficulty of dismantling and reducing work efficiency
