Embodiment Construction

[0045] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0046] see Figure 1-13 , a kind of aviation hydraulic elevator, it comprises bottom frame 1, and the top of described bottom frame 1 is supported and installed with top work platform 4 by scissors lifting mechanism 2, and described scissors lifting mechanism 2 is installed with the top The hydraulic cylinder assembly 5 that is lifted by the working platform 4 is equipped with a cylinder mechanical lock mechanism 8 for self-locking. The hydraulic cylinder assembly 5 is connected with the hand pump structure 6 and provides hydraulic power To drive the jacking action of the hydraulic cylinder assembly 5. By adopting the hydraulic lift with the above structure, it can be used by maintenance personnel to reach the maintenance area with a height of less than 4 meters such as the front equipment cabin, cockpit, fuselage sides and tail of the aircraft to carry...

Abstract

The invention provides an aviation hydraulic elevator, which comprises a bottom machine frame, the top of the bottom machine frame is supported by a scissor fork lift mechanism and provided with a topoperating platform; the scissor fork lift mechanism is provided with a hydraulic cylinder assembly for jacking the top operating platform; a cylinder mechanical lock mechanism for self-locking the hydraulic cylinder assembly is installed on the hydraulic cylinder assembly; the hydraulic cylinder assembly is connected with a hand pump structure and provides hydraulic power to drive the jacking action of the hydraulic cylinder assembly. The lift cylinder structure of the elevator adopts pure mechanical locking device; when an oil pipe suddenly bursts or the cylinder bottom suddenly falls off, the piston rod can be mechanically locked to avoid a sudden fall of the platform and cause a safety accident.

Description

technical field [0001] The invention relates to the field of aircraft maintenance equipment, in particular to an aviation hydraulic elevator. Background technique [0002] The aviation hydraulic lift mainly provides an access platform for the ground crew to complete the maintenance of high-level equipment of the aircraft or as a support platform for disassembling and installing airborne equipment. Most of the existing hydraulic elevators in the army are steel structures, and their jacking power is mainly realized by hydraulic cylinders, which are mainly used as jacking power devices for lifting platforms. [0003] At present, the traditional anti-fall method of the lifting platform is mainly to install an explosion-proof valve at the oil port of the hydraulic cylinder. The road throttle reduces the oil return flow to prevent the platform from falling suddenly, but if the hydraulic cylinder has a failure such as the cylinder bottom suddenly falling off, it will not have the ...
