The invention provides a spring damping vibration attenuation pipeline support with the adjustable prestress. The spring damping vibration attenuation pipeline support comprises two uprights and upright sleeves, wherein the upper ends of the uprights are sleeved with the upright sleeves. The upright sleeves are connected through a connecting beam. Vibration attenuation cavities are formed in the upright sleeves. Damping springs are arranged in the vibration attenuation cavities. The upper ends of the uprights pass through upright channels and buffering vibration attenuation is achieved through the damping springs in the vibration attenuation cavities. Pull rods are arranged between the uprights and the upright sleeves. The distances between the uprights and the upright sleeves are adjusted through nuts at the screw ends of the pull rods, so that the prestress applied by the pull rods is adjusted.

Description
Technical field
The present invention relates to a kind of vibration damping equipment, particularly a kind of mainly to the prestressing force adjustable spring damping vibration attenuation support of pipelines of large-scale pipeline vibration damping being connected with the equipment such as heat pump unit and high powered water pump.
Background technique
The main equipment of complete set must coordinate the pipeline for medium circulation could normal work, as wind-cooling type heat pump unit work time, need the water of uniform temperature to be input to each room by pipeline, thus adjustment room temperature; High-pressure water pump system needs, by pipeline, high pressure water is transported to design height.Can produce stronger vibration during the work of this kind equipment, this vibration also can pass to the pipeline be attached thereto, if these pipeline supports are on floor, the vibration of pipeline will cause the vibration of floor, thus causes noise pollution to indoor.
Room noise problem is caused for solving pipe vibration, general processing mode is that practice shows at support of pipelines place rubber damper, and the pipeline less for diameter can obtain good effect, but for large-diameter pipeline, effectiveness in vibration suppression not person of modern times's meaning of this mode.Engineer proposes again at support place with common spring damping and vibration isolating device supporting pipeline, and so process can reach comparatively ideal effect.
But the horizontal bearing capacity of common spring damping and vibration isolating device is less, pipeline all can to a certain size horizontal force of the damper action at bearing place in construction and operation process.During as constructed, large-diameter pipeline is arranged on the divergence load that on the support of certain altitude, unavoidably generation is larger; As the pipeline temperature influence in operation can produce flexible, can have horizontal direction power to the vibration damper at support place in telescopic process, the longer extending amount of pipeline is larger, and horizontal force is larger.This horizontal force is easy to destroy common spring damping and vibration isolating device, and because of the restriction of size, the connection of this damping shock absorber and support also not easily processes, construction inconvenience.
In addition, do not have liquid in pipe during Pipe installing, after being full of liquid in pipe during equipment work, quality increase is very large, and vibration damper medi-spring can compress further because of the increase of quality, thus cause pipeline commissioning, now the joint of pipeline and equipment can produce larger tensile stress and destroy.Therefore need a kind of prestressing force adjustable shock, during installation, the prestressing force of shock-absorbing spring is transferred to reasonable value, thus further sinking when preventing pipeline from working and destroy joint.
Summary of the invention
, construct inconvenient and shock-absorbing spring prestressing force nonadjustable defect poor for existing pipe shock absorptor horizontal resist forces, propose a kind of prestressing force adjustable spring damping vibration attenuation support of pipelines.
A kind of prestressing force adjustable spring damping vibration attenuation support of pipelines, comprise two root posts and be set in the column sleeve of described column upper end, connected by connecting cross beam between described column sleeve, described column sleeve comprises the column passage of bottom and the vibration damping chamber on top, be provided with shock-absorbing spring in described vibration damping chamber, the shock-absorbing spring buffer shock-absorbing in vibration damping chamber is passed through in the upper end of column after described column passage; In order to avoid pipeline operationally too much sinks, thus ensure the Security at pipeline and equipment connection place, pull bar is provided with between described column and column sleeve, the screw socket end of described pull bar is by the distance between nut adjusting post and column sleeve, thus the prestressing force that regulating tie bar applies shock-absorbing spring, meanwhile, pull bar can also make column sleeve be connected better with column, is convenient to transport and installs.
As preferably, in order to prevent column passage from deforming because conduit wall is too thin, the right angle of described column conduit wall is provided with triangular reinforcing plate, for strengthening the stability of column sleeve.
As preferably, the upper and lower end of described shock-absorbing spring is all connected with backing plate.
As preferably, upper end and/or the lower end of described shock-absorbing spring are provided with damping pad.
As preferably, in order to strengthen column stability at work, the bottom of described column is provided with base plate.
As preferably, described column, column sleeve, connecting cross beam, pull bar and backing plate are all zinc-plated steel structure.
As preferably, described shock-absorbing spring is Martinel Steel spring.
As preferably, described damping pad is rubber pad.
Compared with prior art, the beneficial effect that the present invention has is: composition spring damping and vibration isolating support combined by spring and ordinary stent by the present invention, spring plays the function of vertical vibration damping, and vertical rod and sleeve provide horizontal resist forces, eliminates the shortcoming that current common vibration damper horizontal resist forces is little; In addition, column and column sleeve are linked together with the pull bar of an adjustable length, the prestressing force applied by regulating tie bar, to reasonable value, avoids pipeline operationally too much to sink, thus ensures the Security at pipeline and equipment connection place; Pull bar can also make sleeve be connected better with column, is convenient to transport and installs.
