Description
Technical field
The present invention relates to a kind of Noise and Vibration Control device, especially prevent the mechanical floor pipeline vibration insulation structure that the pipe vibration solid is propagated.
Background technique
The fluid delivery pipeline of equipment is the important component part of device systems, as the good conductor of mechanical vibration, can make the device systems vibration along the long-range propagation of pipeline.Particularly the variation of the medium runnability in the pipeline can make section of tubing produce more serious seismism, strong pipe vibration can make pipeline fittings particularly the connected element of pipeline occur loosening.Under the effect of fluid excitation force, pipeline self also can produce vibration or even intense impact.Be generally used for being equipped with on the pipeline of flexibly mounted machinery, not only pipeline played the yielding support effect, and vibration has good isolation and the significantly effect of reduction construct noise to Management of Pipeline Mechanical Equipment.But in the high place of separating vibration noise requirements, the vibration isolating effect of elastic bearing component just can not meet the demands.Particularly at the water pump of air conditioner mechanical floor in high-rise hotel, very direct on the impact of following floor vibration noise.Not only require very high to the vibration isolation of pump equipment, and, Vibration propagation to pipeline is also very responsive, particularly pump equipment and relevant device in the mechanical floor, pipeline are numerous, be difficult to separate fully with building structure, if vibration isolation only with elastic bearing component, is difficult to reach hotel guest-room to the requirement of ambient noise.
Certain occasion to the exigent situation of vibratory equipment vibration isolation under, when a vibration isolation is not satisfied vibration isolation and required, need to adopt two-stage vibration isolation.The known conditions of the kinetic parameter design of a vibration insulation structure and the definite kinetic parameter of Vibration Absorbing System Design are the known conditions that two-stage vibration isolation designs.The vibration of two-stage vibration isolation structure is delivered in further decay on the basis that the vibration of a vibration insulation structure transmits, and transmits than less and vibration isolating effect is better thereby make.
ZL200820156003.4 discloses a kind of vibration isolator for pipe clamp of pipeline, wherein rubber parts is set as vibration isolator between pipeline and upper and lower sheet metal, utilizes the damping isolation effect of rubber parts, intercepts the Vibration propagation of pipeline.Under general occasion, can satisfy the vibration isolation requirement of pipeline.The major advantage of rubber damper is the obstruct with high-frequency structure vibration, and shock resistance and sound insulation property can satisfy the requirement of Rigidity and strength.The Young's modulus of rubber damper is very little, is a kind of nonlinear elastic material.So the natural frequency of rubber damper is higher, the damping efficiency of low frequency configuration noise is lower.And the impact of mechanical floor pipeline mainly is the solid structure propagation of pipe vibration, take low frequency as main.
Summary of the invention
The solid structure of mechanical floor pipe vibration is propagated the deficiency of control in order to overcome existing vibration isolator for pipe clamp of pipeline, the invention provides a kind of mechanical floor pipeline vibration insulation structure, this mechanical floor pipeline vibration insulation structure can not only effectively be controlled the solid structure of pipe vibration and propagate, and vibration isolation efficiency is high.And can adjust as required the height of vibration insulation structure, guarantee the load balance of relevant device, pipeline.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mechanical floor pipeline vibration insulation structure is comprised of the lower vibration insulation structure that is installed in the pipeline partiting polarization component under the pipeline and be installed between pipeline partiting polarization component and the terrace.The pipeline partiting polarization component is comprised of pipe-supporting frame, elasticity absorbing pad and upper adjustable spring vibration isolator, the integral type member that the pipe-supporting frame is welded into by curved plate, two side force-bearing steel plates and stiffened plate; Lower vibration insulation structure is comprised of vibration isolation mass block, support steel structure, lower adjustable spring vibration isolator and rubber damper, the integral type member that the vibration isolation mass block is formed by steel plate framework structure, counterweight.The spring vibration isolation utensil has static deflection large, and natural frequency is low, and the characteristics that the low frequency vibration isolation performance is good can prevent the low-frequency vibration short circuit.Rubber vibration insulating pad has the good characteristics of high-frequency vibration isolation performance, can prevent the dither short circuit.Pipeline partiting polarization component and the lower vibration insulation structure that is installed under the pipeline partiting polarization component form the two-stage vibration isolation structure, thereby have guaranteed the iris action to pipe vibration.
Described pipe-supporting frame is installed in below the pipeline, and elasticity absorbing pad is set between the pipeline.Upper adjustable spring vibration isolator is installed between the steel plate framework structure of the force-bearing steel plate of pipe-supporting frame and lower vibration insulation structure.The support steel structure welding is at the steel plate framework texture edge, and lower adjustable spring vibration isolator is arranged under the support steel structure, between lower adjustable spring vibration isolator and the terrace rubber damper is set.Described counterweight whole installation forms integral type vibration isolation mass block by the steel plate framework structure under pipeline, counterweight is used steel plate or ingot iron or heavy concrete.If the space under the pipeline is inadequate, the integrated type counterweight can not be set, two limits arrange counterweight under pipeline, form integral type vibration isolation mass block by the steel plate framework structure, also can satisfy the use function of vibration isolation mass block.The quality of vibration isolation mass block is larger under square one, vibration isolating effect better because limited space in the machine room, the volume of vibration isolation mass block is restricted, so the material of counterweight uses hyperbaric material as far as possible.Upper adjustable spring vibration isolator can be a plurality of, is symmetrical arranged along pipe-supporting frame central shaft; Lower adjustable spring vibration isolator can be a plurality of, is symmetrical arranged along vibration isolation mass block central shaft.To enlarge loaded area, improve the harmony of bearing load.Because mechanical floor relevant device, pipeline are numerous, both be connected to each other and separately bearing load be not quite similar, after mechanical floor pipeline vibration insulation structure is set, when the compress variation during owing to each adjustable spring vibration isolator bearing load is inconsistent, can cause relevant device, the pipe level discrepancy in elevation.If there is not the adjustment function of level height, the interface discontinuity equalization of equipment, pipeline enclosure, loosening damage can occur in connected element.
The invention has the beneficial effects as follows, can effectively control the solid structure of pipe vibration and propagate, vibration isolation efficiency is high.And can adjust as required the height of vibration insulation structure, guarantee the load balance of relevant device, pipeline.
