Description

Hang vibration insulation structure
Technical field
The present invention relates to a kind of vibration control technology, especially can intercept the suspension vibration insulation structure that suspended vibration vibration equipment transmits.
Background technique
In engineering equipment installation process, often having various unsettled vibrating conduits, blower fan, static pressure box and the outstanding vibratory equipment of holding high-altitude need to make hanging vibration reduction processes.At present, be more to use vibration reducing lifting hook to process.Vibration reducing lifting hook is simple in structure, at the vibration damping of various pipelines, blower fan, airduct, tracheae, processes very effective.But, exist because the natural frequency of hanging damping spring vibration isolator is single, for unsettled vibratory equipment in speed reducing rotation process, reverse damping torque and can produce opposition, when excited frequency moves closer to the natural frequency of device systems, produce resonance, amplitude will increase.Because suspension device system is resilient hanger, rigidity is poor, if device systems can be produced by force unbalance, rocks, and the connection part of vibratory equipment and device systems is caused damage.Meanwhile, vibration isolating effect is undesirable.
Summary of the invention
In order to overcome existing suspension vibration insulation structure, can not effectively control that the resonance that hangs vibration insulation structure is rocked and the Vibration propagation of vibratory equipment, the invention provides a kind of suspension vibration insulation structure, this suspension vibration insulation structure can not only effectively be controlled the resonance of suspension vibration insulation structure and rock, and can effectively control the Vibration propagation of vibratory equipment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of suspension vibration insulation structure, by hanging damping spring vibration isolator, damping-constraining member, vibration-isolating platform, rubber shock absorber forms, hanging damping spring vibration isolator is arranged on roof building structure, vibration-isolating platform is arranged under the screw rod of hanging damping spring vibration isolator, vibratory equipment is arranged on vibration-isolating platform by vibration damper, between screw rod under hanging damping spring vibration isolator and on vibration-isolating platform, damping-constraining member is set, damping-constraining member can be arranged on vibration-isolating platform surrounding facade, arranged in a crossed manner, screw rod point of intersection between two damping-constraining members arranges rope cramp and fixes.Use the vibration isolator of two kinds of different natural frequencies, form two-stage vibration isolation structure.Because equipment is starting and dwell period, certain in the change procedure of 0 ~ rated speed of the rotating speed in a flash forcing frequency of equipment is unique, and it can not produce resonance with two kinds of different natural frequencies simultaneously, thereby effectively eliminates resonance phenomenon.The level of the controlled vibratory equipment processed of rubber shock absorber is to rocking.Damping-constraining part consists of U-shaped steel plate, clamping bolt and elastic damping plate, two side width of U-shaped steel plate are not etc., one side is broadside, two sides of U-shaped steel plate arrange corresponding clamping bolt mounting hole, the broadside of U-shaped steel plate arranges adjustment bolt mounting holes, the screw rod of hanging damping spring vibration isolator, in U-shaped steel plate, arranges elastic damping plate between screw rod and U-shaped steel plate, by clamping bolt and elastic damping plate, screw rod is reliably installed in U-shaped steel plate.Elastic damping plate can improve the fastening force between U-shaped steel plate and screw rod, also can meet the stress equalization between screw rod and U-shaped steel plate, retrains rocking of screw rod.Tuning link consists of two L shaped steel plates that adjustment bolt mounting holes is all set, L shaped steel plate is connected by bolt adjustment with the broadside of U-shaped steel plate on one side, angle between L shaped steel plate and U-shaped steel plate can be adjusted, and can adapt to the installation requirement of damping-constraining member under different situations.Screw rod, through the adjustment bolt mounting holes of L shaped steel plate another side, is used and adjusts bolt adjustment screw rod effective length.The constraint damping forces of capable of regulating damping-constraining member.
Damping-constraining member can be arranged on vibration-isolating platform surrounding facade, arranged in a crossed manner, also can be arranged between the three-dimensional diagonal angle of vibration-isolating platform, and tiltedly fork arranges, and the screw rod point of intersection between two damping-constraining members arranges rope cramp and fixes.By the setting of damping-constraining member, screw portion and the vibration-isolating platform that can effectively improve below hanging damping spring vibration isolator form integral rigidity, the shaking amplitude of vibration-isolating platform while reducing vibratory equipment excited vibration.
The invention has the beneficial effects as follows, can when the resonance of effect control suspended vibration equipment is rocked, can effectively control the Vibration propagation of vibratory equipment, simple in structure, cheap, easy for installation.
