Abstract

The utility model provides a two-layer equipment base of vibration isolation, with structure that is composed of a pedestal of vibration isolation, vibration isolator, base, guide connecting rod and set bolt. The pedestal of vibration isolation is equipped with an installation hole of bolt for fixing with the equipment base, and the vibration isolator at the bottom of the base is arranged symmetrically on the base according to loads, so as to ensure of approximate equal load on the supporting point of the vibration isolator. The base is fabricated according to the size of the pedestal of vibration isolation, and located at the four corners by the guide connecting rod, and forms a rectangular frame structure of two-layer vibration isolation. The base is equipped with installation hole of screw for fixing vibration isolator at the top, and holes of anchor bolt for fixing with ground at the bottom of four corners. The two-layer equipment base of vibration isolation has the advantage of simple structure, clear force, low natural frequency, good effect of decreasing vibration, convenient installation, reliable performance, good stability and high grade, significantly reducing impact of vibration from equipment and producing active isolation, is mainly used for the vibration reducing of the pump units, ventilation units, blower units and other equipments.

Description

The double-layer vibration isolating plant bottom case

1, technical field

The utility model relates to a kind of plant bottom case, specifically a kind ofly is used to supply water, the double-layer vibration isolating plant bottom case of field related facility such as HVAC.

2, background technique

According to country existing " industrial enterprise's Noise Control Design standard " and pertinent regulations such as " standard of environmental noise of urban area ", be arranged on the independent machine room of industrial building, contiguous residential architecture and public building, or there are interior water pump assembly, ventilation unit, blower unit and other plant bottom cases of occasion such as the concentrated machine room of industrial enterprise of people's operational administrative all should take vibration isolation measure, and the plant bottom case of prior art, what have does not take any vibration insulation and noise reduction measure; Some simple vibration isolation of the only do that has are handled, and as the rubber pad vibration isolation etc., its vibration isolating effect is poor; The employing vibration isolation element that has directly is connected with plant bottom case, exists vibration isolation element shortcomings such as trouble, vibration isolation traveling comfort difference are installed, and therefore, the vibration isolation technique of existing equipment base can not solve well at aspects such as vibration isolating effect and installations.

3, model utility content

The purpose of the present utility model provides a kind of clear and definite, low, good damping result of natural frequency simple in structure, stressed, and easy for installation, reliable performance, good stability, double-layer vibration isolating plant bottom case that class is high.

The technological scheme that its technical problem that solves the utility model adopts is: the double-layer vibration isolating plant bottom case, be by the vibration isolation pedestal, vibration isolator, pedestal, guide connecting rod, the screw mounting hole, compositions such as fixing bolt, be equipped with bolt mounting holes on the vibration isolation pedestal and plant bottom case is fixed, its bottom vibration isolator is pressed the load size in pedestal periphery symmetric arrangement, equate with the load that guarantees each vibration isolator supporting point as far as possible, and the specification of vibration isolator, model, performance and quantity are determined according to its load-bearing quality and stressing conditions, pedestal top is provided with the fixedly screw mounting hole of vibration isolator, pedestal is according to the vibration isolation pedestal system that matches, and locate by guide connecting rod at four jiaos of places, and be the rectangular frame structure of double-layer vibration isolating, the effect of guide connecting rod is: the one, with the vibration isolation pedestal, vibration isolator and pedestal three parts organically make up in aggregates, vibration isolator is contacted with pedestal well with the vibration isolation pedestal, be difficult for breaking away from, also be convenient to simultaneously install and transportation; The 2nd, the power of disturbing that equipment work produced makes the operation of leading up and down in vertical direction of vibration isolation pedestal, reduced the horizontal overturning effect of vibration isolator so widely, improved the stability of vibration insulation and noise reduction, the vibration damper static deflection of the position of guide connecting rod when non-loaded operating mode is installed determined the anchor (bolt) hole that the pedestal tetrapod is furnished with in addition and ground is fixing.

Main feature of the present utility model is: the double-layer vibration isolating plant bottom case takes integrated type to install, its vibration isolation pedestal and pedestal are the rectangular frame structure of double-layer vibration isolating, between vibration isolator is placed in one, the utility model is compared with the isolation mounting of existing equipment base, have simple in structure, stressed clear and definite, natural frequency is low, good damping result, and it is easy for installation, reliable performance, good stability, characteristics such as class height, to reduce vibration equipment to external world influence and to carry out the effect of active vibration isolation remarkable, be mainly used in water pump assembly, the ventilation unit, the vibration damping of blower unit and other equipment unit.

5, embodiment

Just explain below 1,2 pairs of double-layer vibration isolating plant bottom cases of the present utility model of accompanying drawing below.

As accompanying drawing 1, shown in 2, double-layer vibration isolating plant bottom case of the present utility model, be by vibration isolation pedestal [2], vibration isolator [1], pedestal [7], guide connecting rod [3], fixing bolt compositions such as [6], being equipped with bolt mounting holes [8] on the vibration isolation pedestal [2] fixes with plant bottom case, its bottom vibration isolator [1] is pressed the load size in the peripheral symmetric arrangement of pedestal [7], equate with the load that guarantees each vibration isolator [1] supporting point as far as possible, pedestal [7] top is provided with the fixedly screw mounting hole [5] of vibration isolator [1], pedestal [7] is prepared mutually according to vibration isolation pedestal [2], and locate by guide connecting rod [3] at four jiaos of places, the rectangular frame structure that is double-layer vibration isolating, guide connecting rod [3] is with vibration isolation pedestal [2], vibration isolator [1] and pedestal [7] three parts organically make up in aggregates, vibration isolator [1] is contacted with pedestal [7] well with vibration isolation pedestal [2], be difficult for breaking away from, be convenient to install and transportation, the power of disturbing that equipment work produced simultaneously makes vibration isolation pedestal [2] do guiding operation up and down in vertical direction, the power of laterally toppling and the stability that has improved vibration insulation and noise reduction of vibration isolator [1] have been reduced widely, vibration damper [1] static deflection of the position of guide connecting rod [3] when non-loaded operating mode is installed determined the anchor (bolt) hole [4] that pedestal [7] tetrapod is furnished with in addition and ground is fixing.
