Abstract
The present invention relates to a combined shock isolating unit which is composed of a disk spring, a helical steel cable shock-isolating unit and a rigid flexible cable type counterpressure device. The combined shock isolating unit integrates a shock isolating unit and a counterpressure device into one body. The present invention has the advantages of compact structure, convenient construction, long service life and good shock isolating effect and is particularly suitable for being used under the condition of serious impact resistance.
Description
The present invention is a kind of isolator that is combined by belleville spring, screw type cable wire shock absorber and gentle cable-styled back-pressure device.
Isolator of the prior art mostly is by macromolecular material---rubber, helical spring, combinations such as leaf spring or form separately, these isolators can be used for various fields, but from these isolators itself, or at some use occasion, also exist some shortcomings, for example, damping characteristic is relatively poor; Damping and rigidity are difficult for rational Match; Structure is not compact; Macromolecular material is easily aging, and the life-span is short, unstable properties etc.In addition, it is bigger that the isolator that above-mentioned prior art constitutes is used for shockproofness, needs to take the occasion of isolation measure again, often is difficult for obtaining good isolating affection and having long working life.
The objective of the invention is at deficiency of the prior art, design a kind of compact structure, life-span is long, have the in parallel superimposed of good isolating affection, multilayer tandem compound formula isolator is used for the base isolation of machine, equipment with isolator of the present invention, can improve isolation efficiency, increase the service life, simplify the structural type of shock insulating foundation, be convenient to construction.
The main points of the technology of the present invention are to adopt in parallel superimposed, the combined shock isolating unit of multilayer serial fashion, promptly adopt the isolator (1) (hereinafter to be referred as cable wire shock absorber) of multistrand rope coiling type circle to be assembled into one with belleville spring (2), the gentle rope back-pressure amplitude limiter (3) of used rigidity in the time of wherein the resilience of constrained motion object can being installed also, above-mentioned three kinds of parts with being contained in the casing, are promptly constituted the said combined shock isolating unit of the present invention.
The said combined shock isolating unit of the present invention can be installed one or more screw type isolator (1) in a casing; Its screw type cable wire shock absorber (1) is to lie in (as shown in Figure 1) in the casing, on the loam cake (4) and lower cover (5) of the casing that upper and lower two-part of screw type wire rope are fixed respectively.One or more than one belleville spring (2) can be installed in a casing, and its belleville spring (2) is to be in series (as shown in Figure 2) by the staggered superimposed multilayer of multi-disc disc spring film, and is vertically mounted in the casing; Belleville spring (2) can be installed on the belleville spring seat (6), and belleville spring seat (6) (can become the concave station type) is fixed on the lower cover (5) of casing; At the middle part of belleville spring (2) guide cylinder (7) is arranged, the upper end of its guide cylinder (7) is annular entity (8), this annular entity (8) lower surface compresses belleville spring (2), upper surface is fixed on the loam cake (4) of casing, and the middle one-tenth of shrinkage pool (9) that the lower end of guide cylinder (7) puts in belleville spring seat (6) concave station is slidingly matched.One or more than one flexible cable back-pressure device (3) can be installed in a casing, said flexible cable back-pressure device (3) can be made up of stainless steel wire rope or Galvanized Steel Wire Rope, the two ends of its flexible wire ropes are separately fixed on the loam cake (4) and lower cover (5) of casing, or for keeping compact structure, when its flexible cable back-pressure device (3) is installed in belleville spring (2) middle, on the annular entity (8) that the upper end of its wire rope is fixed, the lower end can be fixed on shrinkage pool (9) bottom of belleville spring seat (6) concave station.
Combined shock isolating unit of the present invention has the following advantages:
The life-span of isolator long, do not have aging, can with the machinery equipment equivalent life;
2. work and Environmental Conditions are not had specific (special) requirements, be not subjected to the influence of space environment temperature humidity;
3. have good damping characteristic, be suitable for most moving under the impact condition; Bearing capacity is big;
4. carry amplitude limiter, amplitude fading is fast, and operation especially demonstrates its superperformance under the serious condition of impact, so be particularly suitable for the base isolation of forging hammer;
5. simple in structure, compact, be convenient to construction, install.
Accompanying drawing 1: the isolator (schematic representation) of the screw type circle of multistrand rope coiled;
A) end elevation side view b)
Accompanying drawing 2: the belleville spring (schematic representation) of the superimposed composition of multi-disc disc spring film;
Accompanying drawing 3: combined shock isolating unit principle of compositionality schematic representation;
Accompanying drawing 4: each arrangement of parts scheme (schematic representation) of a kind of combined shock isolating unit.
Combined shock isolating unit of the present invention, can be according to its composing principle according to its different use occasions, operation technique condition and requirement, mounting point and space and be designed to difformity, or arrange cable wire shock absorber, belleville spring and the gentle position of cable-styled back-pressure device in combined shock isolating unit by different modes.Be example with the combined shock isolating unit of rectangle only below, the structure of describing this embodiment constitutes.
The distributing position that accompanying drawing 4 provides each part of embodiment only is schematic representation.Its distributing position is not limited thereto kind of a form in actual applications.In the loam cake (4) of this square type isolator and the surrounding between the lower cover (5), be symmetrically installed with four cable wire shock absorbers (1), each cable wire shock absorber (1) all is fixed on loam cake (4) and the lower cover (5).When the combined shock isolating unit pressurized, cable wire shock absorber is the horizontal ellipse distortion, at this moment, because good vibration-insulation damping effect is played in the rigidity of steel wire itself and the rubbing action between the Steel Wire Strand; When rebounding behind the pressurized, cable wire shock absorber is the vertical ellipse distortion, equally based on above-mentioned principle, plays the damping of decay amplitude.
On four angles of combined shock isolating unit, be symmetrically installed with two or four belleville springs (2) since disc spring film between superimposed relatively in twos, so have bearing capacity preferably, when the isolated component pressurized, damping function is played in the friction between the spring sheet.
For the structure that makes combined shock isolating unit is more compact, can utilize the space in the middle of the disk spring, the gentle anti-pressure device of rope (3) is installed.On the fixing guide cylinder annular entity (8) of the end of the anti-pressure device of rope (3) of will softening, and annular entity (8) is fixed on the loam cake (4), and its other end is fixed on the belleville spring seat (6).Belleville spring seat (6) is fixed on the lower cover (5).(gentle cable-styled back-pressure device also can be installed in the combined shock isolating unit any for the position of installing).The effect of gentle cable-styled back-pressure device is when behind the moving object punching press isolated component during resilience.The effect of playing amplitude limit and quickening to decay.
Around said combined shock isolating unit, a circle protection apron (10) also can be set, its protection apron (10) is installed in loam cake (4) and lower cover (5) respectively all around, and loam cake does not join mutually with the protection apron that covers down.Protection apron also can increase aesthetic feeling except that having protective action.
When concrete and machinery equipment are installed, can as required several combined shock isolating units be arranged by certain requirement and be installed in required occasion, to form a bigger combined type shock-proof device.
