Description
Technical field
This utility model is related to one kind and can automatically experience load pulling force, and automatically adjusts buffering according to load change
The loaded self-adaptive hydraulic buffer system of cylinder efficient pressure, belongs to the technical field of hydraulic pressure.
Background technology
Ship's crane equipped with man-riding winch and high speed rescue boat fall put device because to winch folding and unfolding rate request relatively
Height, generally reaches 30-50m/min.When winch stops suddenly under manned high speed folding and unfolding state, due to inertia have very big
Impact force action is on winch cable, thus having certain danger to occupant on ship, making steel wire rope itself simultaneously and twisting
The brake of car also produces very big shock loading, reduces reliability and service life.Based on this, carry to reduce impact
Lotus, is fitted with greatly hydraulic cylinder and the hydraulic buffer system of accumulator composition at present on such winch.Though this buffer system
So decrease impact to a certain extent, but because its optimum Working is all by rated load design.Actual manned
Winch and high speed rescue boat drop during putting device busy, and load change is very big.For example man-riding winch's rated crew member number exists
15 people, the operating pressure of buffer system oil cylinder must be preset by 15 people.When occupant actual on winch is in 1-2 people, because
Load is too small, and cushion cylinder cannot be retracted, thus leading to this system cannot work, does not have cushioning effect.This buffer system another
Remain high pressure due in oil cylinder, even if piston rod is also at, in storage configuration, state of all stretching out, under marine environment by
Very strong in environment corruption, therefore cylinder piston rod service life is very short, often will change.
In sum, us are needed to design a kind of workload-adaptability good and the new of cylinder piston rod etching problem can be solved
Hydraulic buffer system.
