An arresting hook arm with variable angle and adjustable load

Abstract

The invention discloses an angle-variable load-adjustable arresting hook arm which comprises an arresting hook arm body. One end of the arresting hook arm body is provided with a hook head and the other end is provided with a ratchet wheel. An arresting hook arm lifting hand, the arresting hook arm body, an arresting hook arm angle adjusting device and an arresting hook arm balance weight device are sequentially arranged between the hook head and the ratchet wheel. The hook head is connected with the hook arm body through a bolt. The ratchet wheel comprises a rotary bearing, a ratchet wheel head and a ratchet wheel connection device. The arresting hook arm can be hung to different teeth of the ratchet wheel through the ratchet wheel mechanism device so that the arresting hook arm body can be adjusted at different angles; the purpose of different impact energy can be achieved by placing counter weights on the arresting hook arm body; and furthermore, the angle-variable load-adjustable arresting hook arm is simple in structure and stable and reliable in working performance.

Description

technical field [0001] The invention relates to the technical field of aviation auxiliary mechanical equipment components, in particular to an arresting hook arm with an adjustable load angle, which can verify the impact resistance of a deck coating under different impact loads. Background technique [0002] In order to realize the short-distance arrest of carrier-based aircraft, the arresting hook device is usually used to hook the arresting cable when landing, that is, a set of arresting hook device is installed on the fuselage of the aircraft, which is composed of a hook head and a hook arm. on the belly of the fuselage. The traditional arresting hook arm is a simple rigid structure, including a front hook arm connected to the fuselage, and a rear hook arm, wherein the end of the rear hook arm is a hook head, and a length Adjust the thread, such a rigid structure does not have the effect of buffering and reducing loads, and the load generated by the landing arrest is all...

AI Technical Summary

Problems solved by technology

The traditional arresting hook arm is a simple rigid structure, including a front hook arm connected to the fuselage, and a rear hook arm, wherein the end of the rear hook arm is a hook head, and a length Adjust the screw thread, such a rigid structure does not have the effect of buffering and reducing loads, and the load generated by the landing arrest is completely transmitted to the body structure, requiring the body structure and airborne equipment to have a greater ability to resist axial overload, resulting in increased structural weight and equipment damage. Increased resistance to overload, thereby reducing aircraft combat performance

And it can't realize the adjustment of different angles of the hook arm of the arresting hook, and can't realize functions such as increasing or decreasing the quality of the hook arm, it is difficult to realize the purpose of different impact energies, and it is difficult to ensure stable and reliable working performance
