Description
Technical field
The present invention relates to a kind of combined type lifting platform, the combined type lifting that more particularly to a kind of Airbus Aircraft is used is put down
Platform.
Background technology
Lift occurred as a kind of lowering or hoisting gear, the ancient egypt at B.C. 2800, used manpower drive
Flowing mode.Middle period the 17th century French physician and mathematician Pascal propose and instruct the static pressure of hydraulic transmission technology application to pass
Principle is passed, hydraulic pressure is theoretical and hydraulic transmission technology obtains the development advanced by leaps and bounds afterwards.
Into 20th century, due to the increasingly rise of petroleum industry, people start to be replaced with products from crude oil water as transmission
Medium, has promoted hydraulic transmission technology to emerge again and rapid development and application in transmission field.To the 1950's extremely
The seventies, many companies for being devoted to hydraulic elevating platform production and developing are occurred in that in the world, it is particularly directed to hydraulic pressure electricity
Ladder production and the company for developing.Under the effort of these companies, hydraulic elevating platform realizes large-scale industrial production, it
Structure and species there has also been and develop on a large scale very much, such as straight top type, laterally pushed type, single-unit formula, multi-stag, collateral around rope type, these differences
The hydraulic elevating platform of form goes for many different working environments, in many aspects for we offer convenience.With
All kinds of more ripe and perfect novel hydraulic original paper is used on hydraulic elevating platform, make hydraulic elevating platform stability and
Control accuracy has further raising.
Hoistable platform is various in logistics, carrying, assembling, city parking system, offshore oilfield etc. as a kind of hoisting machinery
It is widely used in workplace.Its main function is to not by drive mechanism with elevating mechanism by object up-down
With height.Wherein hoistable platform is maximum, most important component in whole jacking system, and its structure uses steel plate and beam welding
Form, because platform own wt reaches a sizable magnitude plus the goods for carrying；Wireline system is hoistable platform
Transmission device, by cable wire group, leading block, fasten button etc. constitute.Cable wire is moved repeatedly in the race of leading block, on steel wire
Stress is considerably complicated, and pulling force, bending, extruding and torsion exist simultaneously；The effect of guide rail and leading block is limitation lifting
The transverse movement of platform so as to vertical up-or-down movement can only be made, while the lateral load of hoistable platform can be born；Hydraulic system master
To include hydraulic cylinder component and hydraulic power system two parts.Hydraulic cylinder component be by hydraulic energy transfer be Platform Machinery energy
Part, for hoistable platform provides lifting force.High pressure liquid force feed makes movable pulley and fixed pulley move toward one another and then makes into oil cylinder
Hoistable platform is moved upwards.And moved downward in hoistable platform Action of Gravity Field lower platform, force hydraulic oil to flow out oil cylinder.But hydraulic pressure
The flow of oil turnover oil cylinder controls the speed that hoistable platform runs up and down by main control valve control with this；Control system is lifting
" brain " of platform, it combines the mechanical part in hoistable platform, hydraulic system and electrical equipment etc. to realize
Difference in functionality.
The unstable, loading capacity of existing single mast lift operation is not big enough, and existing scissors fork elevating machine rising or falling speed is slow, work effect
Rate is not high, and the goods for being unsuitable for being directly applied to airliner passenger door is moved.
