AI Technical Summary

Technical Problem

After prolonged use, the anti-slip pads at the bottom of the adjustment feet of the existing landing gear vertical position leakage test bench are prone to damage, making disassembly inconvenient and making it difficult to flip or lift the test bench by weight.

Method used

A landing gear vertical position leakage test bench was designed, which includes a support frame, an elastic locking structure and a hydraulic cylinder. The heavy-duty adjusting feet can be easily disassembled through the elastic locking structure, and the test stability is improved by using the hydraulic cylinder and clamping structure.

Benefits of technology

It enables convenient disassembly of heavy-duty adjustable feet and improves the stability of the test bench, simplifying the maintenance process and improving test efficiency.

Abstract

This invention belongs to the field of landing gear testing technology, specifically relating to a landing gear vertical position leakage test bench, including a base plate, support frames connected to the four corners of the base plate, a top plate fixedly connected to the top of the support frames, three sets of mounting frames fixedly connected to the top of the base plate, a connecting block fixedly connected to the bottom of the top plate, a landing gear disposed between the base plate and the top plate, and three fixing posts fixedly connected between the base plate and the top plate. This invention proposes that by moving the lever to disengage the limiting block and its locking pin from the groove at the top of the mounting block, and then slightly lifting the test bench and pulling the heavy-duty adjusting feet outward, the heavy-duty adjusting feet can be removed from the bottom of the support frame from the side, thus making the disassembly and replacement of the heavy-duty adjusting feet more convenient.
