Description
Technical field
It the utility model is related to a kind of support meanss, and in particular to the support dress to be played a protective role to overhanging piston rod
Put.
Background technology
Hydraulic jack is that hydraulic energy is changed into mechanical energy, does straight reciprocating motion or the hydraulic pressure of oscillating motion performs member
Part.Its simple in construction, reliable operation.During with it to realize reciprocating motion, deceleration device can be removed from, and do not have drive gap,
Stable movement, therefore be used widely in various mechanical hydraulic systems.Hydraulic jack power output and piston rod significant surface
The pressure difference on product and its both sides is directly proportional；Hydraulic jack is substantially by cylinder barrel and cylinder cap, piston rod and piston rod, sealing device, slow
Flushing device forms with exhaust apparatus.For buffer unit with exhaust apparatus depending on concrete application occasion, other devices are then essential.
Using mechanism of the hydraulic jack driving with certain mass in hydraulic system, when hydraulic jack moves to stroke end
There is larger kinetic energy during point, such as do not make deceleration processing, with cylinder cap mechanical collision will occur for hydraulic cylinder piston rod, produce impact,
Noise, there is destructiveness.To relax and preventing this harm from occurring, therefore deceleration device can be set in hydraulic circuit or in cylinder body
Inside set buffer unit.
Hydraulic jack is the executive component that hydraulic energy is converted to mechanical energy in hydraulic system, and its failure can be summarized as substantially
Hydraulic jack malfunction, powerless promote load, piston rod sliding or creep and oil leak etc..Due to hydraulic jack failure
Cause the phenomenon of equipment downtime of common occurrence, therefore, the fault diagnosis and working service that should pay attention to hydraulic jack work.
When the overhanging progress correlation of piston rod, which pushes away, stretches operation, because piston rod has weight, when its extension is longer,
Larger torque can be produced to piston region, it is extremely stressed, influences the sealing ring quality at piston；Meanwhile when
When the object of piston rod extrapolation is supported by piston rod, horizontally disposed piston rod also by great shearing force, easily makes
Rod fracture.
