Description
What the present invention relates to is a kind of automatically levelling damping device, particularly be the automatically levelling vibration damping equipment of the anti-transverse horizontal impact load of many fulcrums band self-locking of vibration dampings such as the equipment installation of pipelinings such as a kind of installation that is used for food production and packing, dynamo-electric stand-alone device, electronic product assembling and railway, bridge.
Generally adopt parallels to adjust the absolute altitude and the levelness of equipment in the installation of electromechanical equipment, all be difficult to guarantee but with the method precision, the duration adjusted be installed, and the applying between parallels and the equipment is not easy to reach technical requirements, working strength is big.Failed Chinese patent CN87205116 discloses a kind of automatically levelling vibration damping equipment that electromechanical equipment is installed that is used for.Adopted spherical pair automatic centering principle to guarantee and the applying of equipment room that the absolute altitude and the level of employing elevating bracket threaded adjusting equipment have also adopted rubber pad and secondary shock absorbing seat to play cushioning effect.But in actual use, bear so the situation that the elevating bracket screw thread is impaired, bonding and slide takes place easily because the weight of equipment and various impact load all are screw threads by elevating bracket, thereby influence the precision of installing and using of equipment.This damping device can only play damping effect to the load of Vertical direction, and under transverse horizontal is hit the situation of loading, can not play cushioning effect.
In view of above reason, the objective of the invention is in order to overcome above deficiency, provide a kind of and can self-locking prevent that the sphere bearing platform is loosening, and not only can play damping effect to the load of Vertical direction but also can play damping effect, guarantee the automatically levelling vibration damping equipment of the anti-transverse horizontal load of many fulcrums band self-locking of installing and using precision of equipment the transverse horizontal impact load.
The object of the present invention is achieved like this:
The automatically levelling vibration damping equipment of the anti-transverse horizontal impact load of many fulcrums of the present invention band self-locking comprises base 2, place the elevating bracket that is connected with whorl of base 3 on the base, be positioned at the sphere bearing platform 4 that cooperates with the elevating bracket sphere on the elevating bracket, it is characterized in that base, sphere bearing platform periphery has at least two holes 5 respectively on the relevant position, through hole 6, one end of at least two position-limited levers 7 passes the through hole on the sphere bearing platform respectively and stretches in the hole on the base, elastic ring 8 is housed between position-limited lever and base aperture, the upper cap nut 9 that is threaded on the position-limited lever is arranged between sphere bearing platform lower end surface and base upper-end surface, lower nut 10, lower nut and base surface of contact are spherical arc, many point bearings, self-locking, can anti-vertical vibration also can anti-transverse horizontal impact load, promptly anti-transverse horizontal vibration.
Hole 5, the through hole 6 on the sphere bearing platform on the above-mentioned base are respectively two, are positioned on base, the sphere bearing platform periphery with respect to sphere bearing platform center line symmetry respectively.
Hole 5 on the above-mentioned sphere bearing platform, the through hole 6 on the sphere bearing platform are respectively a plurality of, are evenly distributed on base, the sphere bearing platform periphery with respect to bearing surface bearing platform center line respectively.
The surface of contact of above-mentioned position-limited lever head and sphere bearing platform upper-end surface is a spherical arc, spacing, vibration damping.
Above-mentioned position-limited lever head, sphere bearing platform upper-end surface have rubber pad 13,14 respectively, can guarantee that position-limited lever head and equipment bottom surface fit automatically, and vibration damping once more.
Be positioned on the above-mentioned position-limited lever that periphery is a polygonal between upper cap nut, lower nut, help using spanner etc. to be regulated, easy to use.
Above-mentioned base bottom surface has neoprene bearing 15, between neoprene bearing and base in the cavity device filler grain is arranged, as sand, sand pottery or duroplasts etc., play certain damping effect.
There is the limited cover that is connected with elevating bracket that contains through hole at above-mentioned elevating bracket lower cavity place, steel ball is contained in the elevating bracket lower cavity and part is exposed the limited cover through hole, a plurality of little steel balls are housed between steel ball and elevating bracket, use a plurality of small balls, can reduce the friction between elevating bracket and steel ball, when needs dismounting or mobile device, be rotated down elevating bracket, make steel ball drop to kiss the earth, just mobile device easily.
All-in-one-piece profile of tooth shift fork is with it arranged on the above-mentioned elevating bracket periphery, and operation elevating bracket adjustment level is convenient.
Referring to Fig. 1, Fig. 2, use when of the present invention, stir the profile of tooth shift fork on the elevating bracket, elevating bracket rises by the connecting thread with base, the absolute altitude of adjustment equipment and levelness reach the requirement of mounting technique, because the sphere bearing platform is that sphere cooperates with elevating bracket, the upper surface of sphere bearing platform can with the bottom automatically levelling of equipment, thereby the upper surface that guarantees the sphere bearing platform contacts applying fully with the bottom of equipment; After lift adjustment finishes; turning lower nut fits the upper surface of position-limited lever and the bottom of equipment; and then turn upper cap nut until the lower surface of being close to the sphere bearing platform; so the weight of equipment and load dispersing are on sphere bearing platform and a plurality of position-limited lever; reduce the stressed of sphere bearing platform, the connecting thread between protection elevating bracket and base, and because the restriction of upper cap nut and lower nut; lock the sphere bearing platform, prevented connecting thread loosening between elevating bracket and base.When the equipment that is mounted is subjected to the transverse horizontal load impact, because the effect of the elastic ring between position-limited lever and base, but antivibration.Dismantle at needs.
During apparatus of the present invention erection unit, conveniently satisfy the adjustment of equipment absolute altitude and substantially horizontal, the energy self-locking prevents that the sphere bearing platform is loosening, guarantees the installation precision of equipment; Owing to adopted multi-point support stressed, improved the stressed distribution of sphere bearing platform, not only can play damping effect, and can play the vibration damping start the transverse horizontal impact load to the load of Vertical direction, thereby prevented the installation precision of equipment that external changing load is influenced, prolonged working life.The present invention is simple in structure, and is easy for operation.
