An airport loading and unloading platform lifting and leveling device

Abstract

The invention discloses a lifting and leveling device for an airport loading and unloading platform, which belongs to the technical field of airport loading and unloading transportation platform equipment. The lifting and leveling device includes a front translation leveling mechanism, a front folding arm, a rear folding arm and a rear translation leveling mechanism; one end of the front folding arm and the rear folding arm is hinged to the chassis, and the other ends of the front folding arm and the rear folding arm are respectively It is hinged with the bottom surface of the loading and unloading platform; the front and rear folding arms realize the lifting or pitching of the loading and unloading platform through the synchronous or independent movement of the lifting cylinder; the front translation leveling mechanism and the rear translation leveling mechanism have a horizontal degree of freedom and four One degree of freedom in the vertical direction, the horizontal degree of freedom movement of the front translation leveling mechanism and the rear translation leveling mechanism realizes the translation or rotation adjustment of the loading and unloading platform, and the combined movement of the vertical degree of freedom realizes the fine adjustment of the loading and unloading platform lifting or tilting left and right degree adjustment. The invention is suitable for working conditions with long loading and unloading platform, high lifting height and low recovery height.

Description

technical field [0001] The invention relates to the technical field of airport loading and unloading transportation platform equipment, in particular to a lifting and leveling device for a mechanical loading and unloading platform. Background technique [0002] The airport loading and unloading platform is an important equipment for cargo loading and unloading and transshipment in the airport. At present, most of the airport lifting and unloading platforms equipped with domestic aviation airports use scissor-type lifting mechanisms. When the platform is long and the lifting height is high, the mechanism The safety and stability of the high position will become very poor, and the space height at the low position will be difficult to reduce to a low enough level. In addition, the current lifting loading and unloading platforms in the domestic market can only achieve simple lifting movements, which have too high technical requirements for operators, which is not conducive to pr...

[0002] The airport loading and unloading platform is an important equipment for cargo loading and unloading and transshipment in the airport. At present, most of the airport lifting and unloading platforms equipped with domestic aviation airports use scissor-type lifting mechanisms. When the platform is long and the lifting height is high, the mechanism The safety and stability of the high position will become very poor, and the space height at the low position is difficult to reduce to a low enough level

In addition, the current lifting loading and unloading platforms in the domestic market can only achieve simple lifting movements, which have too high technical requirements for operators, which is not conducive to precise docking with warehouses and affects loading and unloading efficiency
