Description
Technical field
The present invention relates to a kind of vibration insulation structure limit stoper, the large load damping snubber of vibration insulation structure displacement of especially can system for restricting floating.
Background technique
Vibration isolation technology is the effective means that vibration and noise are controlled, and by people, is familiar with.Main equipment also trends towards being transitioned into elastic base by rigid foundation, owing to adopting vibration isolation technique to obtain good result.Its main circulation way of vibration equipment noise is the construct noise transmitting by building structure with low-frequency vibration.The vibration transmission of attenuation apparatus is to realize by eliminating being rigidly connected between them.The method of dealing with problems is at present, main equipment is arranged on by being equivalent to weight of equipment 2-5 rigid block doubly, vibration isolator is set under rigid block or the floating vibration insulation structure of building forms isolation mount.In engineering practice, the vibration producing in running due to equipment can cause the displacement of rigid block, or produce between rigid block and isolation mount pit wall and contact and cause vibration isolation inefficacy, or the equipment of generation vibration insulation structure level is rocked to displacement, has influence on thus the normal operation of equipment.Due to main equipment and mass rigid mass block very large, once produce displacement, be difficult to adjust.At present, not yet there is suitable large load damping snubber application.
Summary of the invention
The displacement producing in order to overcome the vibration insulation structure of main equipment setting, the invention provides a kind of large load damping snubber, this large load damping snubber can not only be controlled the displacement of main equipment vibration insulation structure, and can adjust easily and vibration insulation structure between spacing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of large load damping snubber, and by fixedly load-carrying member, gap adjusting structure, elastic damping member, dust cover form.Described fixedly load-carrying member is comprised of steel base plate, square plate structure, force bearing plate, stiffened plate, rubber rubbing cushion, fixing bolt, square plate structure welding is on steel base plate, force bearing plate is welded on square plate structure bottom, stiffened plate is welded on surrounding above square plate structure, steel base plate surrounding arranges mounting hole and uses fixing bolt to be arranged on fondational structure, and rubber rubbing cushion is set between steel base plate and fondational structure; Described elastic damping member is by steel structure and rubber combined making, elastic damping member is U-shaped structure, outer surface is all rubber-coated, and its internal surface is trihedral steel plate structure, with the square plate structure of fixing load-carrying member above and left and right leave adjusting play.
Described elastic damping member is placed on the force bearing plate of the fixing square plate structure bottom of load-carrying member.Described gap adjusting structure is by longitudinal lock bolt, longitudinally back down bolt, and bolt is laterally backed down on two limits, to adjust the fixedly gap between load-carrying member and elastic damping member; The nut-welding that longitudinally backs down bolt is in the fixing square plate structure inner side of load-carrying member, and longitudinally lock bolt coordinates with the screw of elastic damping member, backs down, the length travel of lock bolt adjustment elastic damping member by rotating longitudinally; The nut-welding that bolt is laterally backed down on two limits, in the fixing square plate structure inner side of load-carrying member, laterally backs down by rotating two limits the lateral displacement that bolt is adjusted elastic damping member.Can adjust the spacing with equipment rigid block.Elastic damping member and the normality between vibration insulation structure of floating leave certain gap, can prevent that low-frequency vibration from transmitting by damping snubber, produce low-frequency vibration short circuit.The group number of damping snubber can be set according to actual conditions, is greater than the dynamic load sum of equipment dynamic load and equipment rigid block to meet total load scope.Described dust cover consists of square plate, is arranged on the stiffened plate of fixing load-carrying member by fixing bolt, and the edge with equipment vibration insulation structure is hidden.
The invention has the beneficial effects as follows, can be when controlling the displacement of main equipment vibration insulation structure, adjust easily and the rigid block of equipment vibration insulation structure between spacing, bearing load is large, can change elastic damping member, maintains easily.
