Description
Technical field
It the utility model is related to the multi-storied garage of the wire rope synchronous device and application of a kind of hydraulic lifting equipment device.
Background technology
When two hydraulic cylinders lift or promote a weight at the same time, often there are stationary problem, device needs to use speed
Or position synchronous balance control methods keep stress equalization or the position in lifting process steady, in case lifting object run-off the straight is fallen
Fall, or due to causing a certain orientation of platform to support load to form security risk in non-horizontal lifting state for a long time.
Double hydraulic cylinder lifting Synchronization Control mainly has two methods at present, and one kind is hydraulic synchronization, and another kind is mechanical same
Step.Hydraulic synchronization mainly uses Hydraulic Synchronizing Valve, hydraulic cylinder tracing compensation each other.This method changes very big field for load
Conjunction synchronization accuracy is not high, and the cost of hydraulic synchronization is also higher.
Mechanical synchronization has two methods again, and steel wire rope is synchronous and structural rigidity is synchronous.Structural rigidity is synchronously to be directed to main body
The angle of structure or position change device, using the very strong structure of a rigidity, no matter oil cylinder thrust it is inconsistent or
External load is inconsistent, the rigid structure can be relied on to keep the steady all the time of article carrying platform, it is clear that the shortcomings that this method is
Occupy lot of materials so that equipment is very heavy.The more auto repair hydraulic jack of current application, using two steel
Cord connects the hydraulic cylinder on both sides and lifting device, ensures that both sides height is consistent at any time, and this method application is more
Generally.But it requires the angles and positions of main structure body to remain motionless, the occasion adaptability changed for structural point
It is not strong.
