A kind of hydraulic cylinder of elevator
Technical field
The present invention relates to the field of lowering or hoisting gear, particularly relate to the hydraulic cylinder of a kind of elevator.
Background technology
Along with the growing growth of modern industrial technology, mechanical processing industry is also more and more higher to the requirement of logistics device, stand-by heavier work pieces is transferred to processing site, weight is delivered to the platform with certain altitude, goods vanning is required for substantial amounts of manpower and materials, thus waste substantial amounts of resource, but the demand of production may not necessarily be fully met, now also must complete by instrument, how to go out less power and easily carry heavier workpiece, not just moving heavy object and also goods is transported to certain height, upper-lower height is adjustable, therefore this series of demands are met in the urgent need to a kind of new device.
Summary of the invention
The technical problem that present invention mainly solves is to provide the hydraulic cylinder of a kind of elevator, is provided with first stage piston and second piston, and area processed is little, stroke is big, compact conformation, flexible stretching structure oil cylinder group flexible, reliable, improve the service life of oil cylinder, greatly reduce the fault rate of oil cylinder group.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide the hydraulic cylinder of a kind of elevator, including drive end bearing bracket, rear end cap, cylinder body, piston rod, fairlead, first stage piston and second piston, described drive end bearing bracket and rear end cap are separately positioned on the rear and front end of cylinder body, described piston rod is arranged on the center of cylinder interior by fairlead and protrudes from rear end cap, described first stage piston and second piston are arranged on the inwall of cylinder body, and described first stage piston is arranged on the front end of second piston.
In a preferred embodiment of the present invention, described fairlead is arranged on the front end of piston rod and is positioned at cylinder interior.
In a preferred embodiment of the present invention, the hydraulic cylinder of described elevator also includes pressing plate, and described pressing plate is arranged between fairlead and piston rod.
In a preferred embodiment of the present invention, the hydraulic cylinder of described elevator also includes oil-out and oil-in, and described oil-out and oil-in are separately positioned on the front-end and back-end of cylinder body.
The invention has the beneficial effects as follows: the hydraulic cylinder of the elevator of the present invention, being provided with first stage piston and second piston, area processed is little, stroke is big, compact conformation, flexible stretching structure oil cylinder group flexible, reliable, improve the service life of oil cylinder, greatly reduce the fault rate of oil cylinder group.
Accompanying drawing explanation
