Description
Technical field
The present invention relates to a kind of vibration insulation structure limit stoper, especially can the large load damping snubber of system for restricting floating vibration insulation structure displacement.
Background technique
Isolating technique technology is an effective means of vibration and noise control, be familiar with by people.Main equipment also trends towards being transitioned into elastic base by rigid foundation, achieves good result owing to adopting vibration isolation technique.Its main circulation way of vibration equipment noise is the construct noise transmitted by building structure with low-frequency vibration.The vibration passing of attenuation apparatus realizes by eliminating being rigidly connected between them.The method of dealing with problems at present is, is arranged on by main equipment by being equivalent to weight of equipment 2-5 rigid block doubly, arranges vibration isolator or float to build vibration insulation structure composition isolation mount under rigid block.In engineering practice, the vibration produced in running due to equipment can cause the displacement of rigid block, or the Contact producing rigid block and isolation mount pit wall causes vibration isolation to be lost efficacy, or the equipment of generation vibration insulation structure level is rocked to displacement, has influence on the normal operation of equipment thus.Because main equipment and mass rigid mass block thereof are very large, once produce displacement, be difficult to adjustment.At present, suitable large load damping snubber application is not yet had.
Summary of the invention
The displacement that the vibration insulation structure arranged to overcome main equipment produces, the invention provides a kind of large load damping snubber, this large load damping snubber can not only control the displacement of main equipment vibration insulation structure, and can adjust the spacing between vibration insulation structure easily.
The technical solution adopted for the present invention to solve the technical problems is: a kind of large load damping snubber, is made up of fixing load-carrying member, gap adjusting structure, elastic damping component, dust cover.Described fixing load-carrying member is made up of steel substrate, square plate structure, force bearing plate, stiffened plate, rubber rubbing cushion, fixing bolt, square plate structure welding is on steel substrate, force bearing plate is welded on square plate structure bottom, stiffened plate is welded on square plate structure surrounding, steel substrate surrounding arranges mounting hole and uses fixing bolt to be arranged on fondational structure, arranges rubber rubbing cushion between steel substrate and fondational structure; Described elastic damping component is by steel structure and rubber combinedly make, elastic damping component is U-shaped structure, outer surface is all rubber-coated, and its internal surface is trihedral steel plate structure, leaves adjusting play with before the square plate structure of fixing load-carrying member and left and right.
Described elastic damping component is placed on the force bearing plate of square plate structure bottom of fixing load-carrying member.Described gap adjusting structure backs down bolt by longitudinal lock bolt, longitudinal direction, and bolt is laterally backed down, to adjust the gap between fixing load-carrying member and elastic damping component in two limits; Longitudinally back down the nut-welding of bolt inside the square plate structure of fixing load-carrying member, longitudinal lock bolt coordinates with the screw of elastic damping component, and by rotating, longitudinal direction is backed down, the length travel of lock bolt adjustment elastic damping component; The nut-welding of bolt is laterally backed down inside the square plate structure of fixing load-carrying member in two limits, laterally backs down the lateral displacement of bolt adjustment elastic damping component by rotating two limits.The spacing with equipment rigid block can be adjusted.Between elastic damping component and floating vibration insulation structure, normality leaves certain gap, can prevent low-frequency vibration from being transmitted by damping snubber, produces low-frequency vibration short circuit.The group number of damping snubber can set according to actual conditions, to meet the dynamic load sum that total load scope is greater than equipment dynamic load and equipment rigid block.Described dust cover is made up of square plate, is arranged on the stiffened plate of fixing load-carrying member by fixing bolt, is hidden at the edge with equipment vibration insulation structure.
The invention has the beneficial effects as follows, can while the displacement of control main equipment vibration insulation structure, the spacing easily between adjustment and the rigid block of equipment vibration insulation structure, bearing load is large, can change elastic damping component, maintain easily.
