Description
Technical field
The utility model relates to a kind of anti-leak damper, and particularly a kind of Shaftless anti-leakage viscous damper can be applicable to control of building structure vibration damping and locomotive vibration damping.Also can be used for vibration damping, buffering and the vibration control in fields such as space flight, electronics, chemical industry, the energy, instrument, medical treatment, health.
Background technique
Viscous damper is the class viscous damping dissipation vibrational energy that utilizes viscous liquid, the device that suppresses vibration amplitude, uses very extensively at industrial field, and the application in civil engineering structure has in recent years also increased gradually.The structure of common viscous damper comprises oil cylinder, piston head, piston rod, sealed member etc.How to prevent that viscous liquid from leaking from the separating surface between piston rod and the cylinder barrel is one of key issue of viscous damper.The viscous damper that the is applied to civil engineering structure tonnage of exerting oneself generally requires at least more than 100,000 Ns, thereby in-oil cylinder fluid pressure is very high during its work, and higher to the requirement of sealed member, the damper cost is corresponding significantly to be increased.And, in engineering structure during one's term of military service, also need make regular check on its leakage situation, therefore the maintenance cost that produces is not low yet.The utility model will fundamentally solve the problem that viscous liquid is leaked, and reduce its cost.
The model utility content
The utility model has proposed a kind of anti-leak damper in order to solve the above-mentioned defective of existing viscous damper, makes damper not have the possibility of leakage on principle.
To achieve these goals, the utility model has been taked following technological scheme:
A kind of anti-leak damper, include sleeve, guide rod, sleeve band hinge first member plate, the slip end plate, the sleeve right end plate, band is hinged end plate, left side bellows, right bellows, viscous liquid, damping hole, hand-hole, exhaust port, the hinge head, pilot hole, it is characterized in that: sleeve band hinge first member plate and sleeve right end plate are welded on two ends, the sleeve left and right sides respectively, have damping hole and pilot hole on the sleeve right end plate, left side bellows and right bellows are welded in respectively on the two sides, the left and right sides of sleeve right end plate, damping hole is communicated with left bellows and right bellows, be full of in left side bellows and right bellows and the damping hole viscous liquid or viscose glue body are arranged, guide rod passes the pilot hole on the sleeve right end plate, pilot hole and guide rod all are arranged at the left bellows and the right bellows outside, the left justify of guide rod and left bellows is welded on the slip end plate, the right-hand justified of guide rod and right bellows is welded on band and is hinged on the end plate, band is hinged end plate and is provided with hand-hole and exhaust port, hand-hole is used for bellows and right bellows interior perfusion viscous liquid or viscose glue body left, when being used to pour into, exhaust port discharges the air in left bellows and the right bellows, be provided with the antiseepage screw rod on hand-hole and the exhaust port and be used to seal hand-hole and exhaust port, the hinge head is connected to is with hinge sleeve first member plate and band to be hinged the outside of end plate.
When band was hinged the relative sleeve of end plate to left movement, left bellows was stretched, and right bellows is compressed, and the viscous liquid of ordering about in the right bellows enters left bellows by the damping hole on the sleeve right end plate.Same, when band is hinged the relative sleeve of end plate when moving right, the viscous liquid that drives in the left bellows is entered right bellows by damping hole.The damping force of anti-leak damper equals viscous liquid and passes fluid pressure on the viscous force of damping hole, the sleeve right end plate, three sums of bellows distortion restoring force, and power consumption is then mainly from the elastic plastic behavior of viscous force and bellows.
The anti-leak damper that the utility model proposes can obtain following beneficial effect:
1), thereby can prevent leak of liquid owing to do not had piston rod, viscous liquid to be sealed in the astomous container.
2) because the existence of bellows restoring force makes the anti-leak damper also have from the return function, promptly damper can return to reset condition in the situation that does not have external force.
