Abstract
The utility model discloses a metal-rubber vibration isolator with composite rigidity for an oil rig and mainly aims at solving the problem that the vibration isolator of the base of the rig in the prior art adopts a spring for vibration isolation and the vibration isolation effect is not good due to the over-heavy load of the whole rig system. The metal-rubber vibration isolator is characterized in that a flat plate, a rectangular support frame and four right-trapezoid fixed plates are connected in sequence to form a lower base (1); an upper base (4) is the same as the lower base (1) in structure but opposite in space position; and between the upper base (4) and the lower base (1), the four right-angle parts of the rectangle are respectively fixed with a metal spiral spring (2) that is internally lined with a metal-rubber sleeve (3). The metal-rubber vibration isolator dissipates energy by the friction of metal wires, thus reducing the spreading of the vibration energy; and used for basic support and vibration isolation for the base of the rig, the metal-rubber vibration isolator can not only ensure good installation rigidity and stability, but also play excellent isolating effect for the vibration of the rig system.
Description
Technical field
The utility model relates to a kind of vibration isolator that rig substructure is accomplished the active vibration isolation function that is used for.
Background technique
In field drilling, rig, derrick, traveling system and special tool thereof have constituted the important component part of oil drilling equipment.Rig is installed on the base platform, and upright leg of derrick and Shears stack mounting are on pedestal is gone ashore.The inertial load that produces in the time of equipment self-weight and work, oscillating load etc. are delivered on the rig pedestal through base, the upright leg of derrick.For many years; Structural designs such as oil derrick adopt static strength as main criteria traditionally; According to the unlikely standard of destroying as design under the service condition, one-sided increasing safety coefficient simply causes structure huge, heavy; Not only increase cost, and increased the weight of borer system virtually.Except the deadweight of bearing the said equipment, the prior influence that also will bear dynamic load of borer system, effects such as vibration that produces during like hook load, wind load and rig vibration and impulsive load.Huge quality system causes life-span of equipment and bearing capacity to have a strong impact on, and site operation personnel and equipment is constituted potential safety hazard under the oscillating load effect.Rig substructure vibration isolator of the prior art adopts spring vibration isolation, because the load of whole borer system is excessive, therefore, its vibration isolating effect is bad.
Summary of the invention
The technical problem of mentioning in order to solve in the background technique; The utility model provides the metallic rubber vibration isolator of a kind of oil-well rig with composite rigidity; This kind oil-well rig adopts the elastic porous material metal-rubber to constitute vibration isolator as elastic damping element and the combined back of helical spring with the metallic rubber vibration isolator of composite rigidity, through wire friction dissipation energy, the propagation of having cut down vibrational energy; Be used for the foundation support and the vibration isolation of rig pedestal; Can guarantee to install preferably rigidity and stability, can play vibration isolating effect preferably to the borer system vibration again, have popularizing prospect widely.
The technological scheme of the utility model is: this kind oil-well rig is with the metallic rubber vibration isolator of composite rigidity; Comprise bottom base 1 and top base 4; Wherein, Said bottom base 1 constitutes after being connected successively by one flat plate, a rectangle supporting frame and four right-angled trapezium fixed plates, and said top base 4 is identical with bottom base 1 structure but the spatial position is in opposite direction; Be positioned at four square position places of rectangle between said top base 4 and the bottom base 1, be fixed with the metal coil spring 2 of an inner liner metal rubber sleeve 3 respectively through stud bolt 5.
The utlity model has following beneficial effect: this kind device is because of based on metal-rubber friction energy-dissipating principle, and helical spring sound stiffness Calculation and actual measured value basically identical, and long-term big loading is difficult for producing crisp phenomenon; Steady performance; Advantages such as the vibration isolator after the combination has possessed rigidity and good stability, and the strong and damping capacity of energy dissipation capability is superior play good result to the vibration vibration isolation of rig and the big quality system of this type of base thereof; Be the metallic material combination because of its vibration isolation unit simultaneously; The bearable environment temperature excursion is big, does not receive burn into oil stain and dust condition restriction, has very strong environmental suitability.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of single metal helical spring and metal-rubber cover combination back structure.
1-bottom base among the figure, 2-metal coil spring, 3-metal-rubber cover, 4-top base, 5-stud bolt.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; This kind of oil-well rig is with the metallic rubber vibration isolator of composite rigidity; Comprise bottom base 1 and top base 4; Wherein, said bottom base 1 constitutes after being connected successively by one flat plate, a rectangle supporting frame and four right-angled trapezium fixed plates, and said top base 4 is identical with bottom base 1 structure but the spatial position is in opposite direction; Be positioned at four square position places of rectangle between said top base 4 and the bottom base 1, be fixed with the metal coil spring 2 of an inner liner metal rubber sleeve 3 respectively through stud bolt 5.
During practical implementation, metal coil spring 2 overlaps 3 coaxial combination with metal-rubber to be installed, and the combined altitudes of metal-rubber cover equals peripheral helical spring height.When bolt is installed the elasticity composition element is implemented certain precompressed distortion.Vibration isolator is installed in rig substructure in groups when using and goes ashore between the base steel plinth.Because the long-term big loading of helical spring is difficult for producing crisp phenomenon, stable performance can guarantee to install preferably rigidity, and vibration isolator is installed in groups simultaneously, is difficult for unbalance loading, has good carrying and stability when rig substructure is installed.The metal-rubber cover is a kind ofly to be processed through the elastic porous material of the coiling and the aftershaping of colding pressing by the fixing wire alloy of the trade mark; During the rig substructure vibration; Make its axial compression, in a big way, belong to resiliently deformable, wire rolls each other and rubs; Cause vibrational energy to dissipate, thereby reduced the propagation of vibrational energy.The combination of metal-rubber and helical spring all is metal materials, does not receive the severe rugged environment conditionality, has very strong environmental suitability, can assemble for a long time be used for open-air drilling well and high low temperature, temper, the vibration under the condition such as corrosion isolates.
Utilize isolation mounting in this device, the dissipates vibration energy reduces or weakens the propagation of vibration, is one of popular approach of present engineering field solution hazard of vibration problem.Metal coil spring is usually used in low frequency vibration isolation, have advantages such as high-low temperature resistant, oil resistant, corrosion-resistant, aging, life-span length, low price, but damping capacity is poor.Metal rubber material is according to the structure of molecule simulation technique, and the fixing fine wire raw material of the trade mark is manufactured fixed shape through twining with cold punching technology, as the vibration isolator elastic damping element, has the high elasticity of rubber like, damping characteristic greatly.Metal coil spring and metal-rubber modular design are made vibration isolator; Be used for the foundation support and the vibration isolation of rig pedestal; Can guarantee to install preferably rigidity and stability, can play vibration isolating effect preferably to the borer system vibration again, be with a wide range of applications.
