Abstract
A shock absorber for a movable screw air compressor comprises a base with a hollow structure, wherein mounting holes used for being connected to a bearing base are formed in a lower bottom plate of the base; a through hole I is formed in the middle of the lower bottom plate of the base; a through hole II is formed in a protuberance part corresponding to the through hole I, in the base; a metal outer cover is connected to the protuberance part of the base through solid rubber; a through hole III is formed in a position corresponding to the through hole II, in the metal outer cover; a flexible buckle type support used for mounting a screw of the movable air compressor is movably clamped at the through hole II and the through hole III. By adopting the shock absorber, a shock-absorbing structure and a shock-absorbing effect of the movable screw air compressor can not be affected by external factors under special working conditions and environment.
Description
Technical field
The utility model relates to a kind of mobile screw air compressor damping device.
Background technique
Existing mobile screw air compressor damping device is to fill the solid rubber structure in the middle of adopting the two ends metal flat, the physical shock produced while by the contractibility that is filled in intermediate solid rubber, reducing the helical-lobe compressor unit operation, but the mobile screw air compressor is usually owing in transportation and actual the use, can not keeping well the horizontality of its placement, the vibration damper stress surface tilts, easily cause the vibration damper vibration displacement of this structure produce resonance and amplify, or even cause the intermediate rubber fault rupture, make and have in actual applications the technology drawback.
Summary of the invention
Goal of the invention of the present utility model is to overcome the prior art above shortcomings and a kind of mobile screw air compressor vibration damper that can make mobile screw air compressor its shock-damping structure and effect under special industrial and mineral and environment not be subject to external factors and change is provided.
The technical solution of the utility model is: comprise that one has the pedestal of hollow structure; Described pedestal lower shoe is provided with the mounting hole for being connected with the load-bearing base; Be provided with through hole one in the middle of described pedestal lower shoe; Ridge on the pedestal corresponding with through hole one is provided with through hole two; Metal housing is connected with the pedestal ridge through solid rubber; Be provided with through hole three with through hole two corresponding parts on metal housing; Be loaded on through hole two, through hole three places for the knot that can be undone by a pull cribbing moving card that the air compressor screw rod is installed.
Described knot that can be undone by a pull cribbing is a cylinder, and its upper end has along the outward extending upper outer of its radially-outer surface, and there is outward extending lower outer lower end; On described knot that can be undone by a pull cribbing, the outer external diameter is greater than through hole three diameters, and lower outer external diameter is greater than through hole two diameters; Block mutually with the metal housing upper surface the upper outer of described knot that can be undone by a pull cribbing, and block mutually with the inwall of pedestal ridge lower outer.
On described metal housing, through hole three is step hole, and its stepped part is blocked mutually with the upper outer of knot that can be undone by a pull cribbing.
Described knot that can be undone by a pull cribbing cylinder place external diameter is less than through hole two diameters.
Described solid rubber is filled in the cavity that metal housing, knot that can be undone by a pull cribbing, pedestal surround.
Described knot that can be undone by a pull cribbing inwall is provided with the internal thread for being connected with the air compressor screw rod.
Can freely determine constant bearing by the through hole of pedestal below according to the as installed demand, mounting type no longer can only be fixed downwards from stress surface as traditional shock absorber.
The utility model avoid the mobile screw air compressor in transportation and actual the use because the vibration damper stress surface tilts and the vibration displacement skewness, the vibration displacement resonance caused and the technical problems such as amplification and intermediate rubber fault rupture.
The utility model is arranged between screw host and power system and load-bearing base, in equipment operation or moving process, interaction force generation mechanical shock due to displacement and gravity, easily each parts of whole mobile screw air compressor unit are produced the transmission of vibrations, cause parts damages, now be arranged on the vibration damper of screw host and power system below, the physical property of the solid rubber of filling by centre is stretched and is made vibratory source cancel out each other the blocking-up vibration displacement to the miscellaneous part transmission, reaches damping effect and purpose.
The accompanying drawing explanation
Further illustrate the utility model below in conjunction with drawings and Examples.
Fig. 1 is stereogram of the present utility model.
Fig. 2 is cut-away view of the present utility model.
Embodiment
In Fig. 1, the utility model comprises that one has the pedestal 1 of hollow structure, and pedestal 1 lower shoe is provided with mounting hole 5, and knot that can be undone by a pull cribbing 3 moving card are loaded in the middle of metal housing 4 and pedestal 1.
In Fig. 2, in the middle of pedestal 1 lower shoe, be provided with through hole 1, the ridge on the pedestal 1 corresponding with through hole 1 is provided with through hole two, and metal housing 4 is connected with pedestal 1 ridge through solid rubber 2.Solid rubber 2 is filled in the cavity that metal housing 4, knot that can be undone by a pull cribbing 3, pedestal 1 surround.Be provided with the through hole three of stepped shape on metal housing 4 with through hole two corresponding parts, knot that can be undone by a pull cribbing 3 moving card are loaded on through hole two, through hole three places.Knot that can be undone by a pull cribbing 3 is a cylinder, and its upper end has along the outward extending upper outer of its radially-outer surface, and there is outward extending lower outer lower end.Block mutually with the stepped part of through hole three the upper outer of knot that can be undone by a pull cribbing 3, and the lower outer via through holes two of knot that can be undone by a pull cribbing 3 blocks mutually with the inwall of pedestal 1 ridge.
Actually use and operate, pass through mounting hole 5 with screw, whole vibration damper is fixed on the load-bearing base, can be connected screw host fix rigging position with the load-bearing base with power system through screw from top to bottom or from bottom to top by through hole 6, at first the vibration displacement produced when the mobile screw air compressor unit works is to be delivered on metal housing 4, be delivered to again the solid rubber 2 in the middle of being filled in, due to the physical property of solid rubber 2 can be because of applied external force free-extension, because metal housing 4 is connected with employing knot that can be undone by a pull cribbing 3 in the middle of pedestal 1, the active force that vibration displacement produces can change the gap of knot that can be undone by a pull cribbing 3 and pedestal 1, just the vibration displacement bounce-back can be offset, in the non-horizontal positioned of mobile screw air compressor unit or while working in movement, while it is characterized in that vibration displacement is delivered to metal housing 4, because metal housing 4 adopts the bell-jar type design, its structure has increased the area of contact of stress surface and solid rubber 2 greatly, therefore can proofread and correct the non-horizontal applied force that tilts to produce because of center of gravity makes the gap between solid rubber 2 physical property stretchability inequalities and knot that can be undone by a pull cribbing 3 and pedestal 1 can not along continuous straight runs technical problem vertically downward, therefore the vibration displacement be delivered on pedestal just can reduce even and cut off, so vibratory source can not transmitted to the load-bearing base again, guaranteed that whole unit vibration displacement is in rational scope.
