Description
Technical field
Spring support hanging frame is designed according to principle of moment balance, in defined load displacement range, loading moment and bullet
Spring force square remains balance.Therefore, with when perseverance hangs the pipeline of support and equipment is subjected to displacement, constant bearing can be obtained
Power will not carry out additional stress to pipeline and equipment belt.Perseverance hangs the place for being generally used for needing to reduce displacement stress, such as station boiler
Ontology, foil portions and the petrochemical equipments such as vapour, water, cigarette air hose and the burner in power plant and other needs to reduce position
Move the place of stress.
In practical application such as: point of suspension in tracheae, water pipe and the petroleum of Thermal Power Station, the pipe-line system of chemical industry
Thermal walking it is very big, up to several millimeters, tens millimeters arrive several hundred millimeters, if using common suspension apparatus, suspension apparatus bear
Load by be normal load several times more than, being suspended pipe-line equipment will be severely deformed, brings very big additional stress, sternly
Ghost image rings the safety of pipe-line equipment and the equipment safety in entire power station, in order to avoid pipe-line system generate dangerous bending stress and
Unfavorable stress transfer, suspension and support should be flexible, using one kind when being suspended pipe-line equipment and being subjected to displacement, are still able to maintain perseverance
Determine the Suspenoing apparatus of supporting force, this equipment is known as constant supporting spring hanger, and then constant hanger is widely used, constant force branch
Hanger is the important auxiliary of steam power plant, and performance directly influences steam power plant safety, reliability, Nai Zhiying
Ring the economic development to China.
Stability of the suspension and support into use how is improved, is always the Main way of research.In the prior art in order to mention
The stability of high suspension and support under vibration；The patent No. 02138291.3, entitled " no spring pull rod dual AC power frame disk spring
The patented technology of suspension and support " is disclosed a kind of suspension and support formed using disc spring and power switching mechanism, become to adapt to load
Change, load-carrying ability is changed by adjustment spring tensile force.In the patent, spring carries load in the power of input terminal completely；?
When load-bearing material deforms, damping can only be carried out by disc spring.Similarly such as Chinese patent CN101545562, a kind of spring hanger,
Including cylinder, the intracorporal spring of cylinder, load bolt, gland, the power switching mechanism that cylinder lower part is arranged in, flexible connection are set
Tightening nut in power switching mechanism lower end, be equipped in cylinder close at barrel at least three on the same circumference, with
The parallel guide rod of tubular axis, spring are located between guide rod.In addition the disc spring in disc spring group is the edge by disc spring
Stress is carried out, disc spring edge easily deforms or fissions in use process.The patent No. 02138291.3, entitled " no bullet
The patented technology of spring pull rod dual AC power frame disc shape spring support hanger frame " discloses a kind of utilization disc spring and power switching mechanism group
At suspension and support, for adapt to load change, pass through adjustment spring tensile force change load-carrying ability.In the patent, spring is held completely
Load has been carried in the power of input terminal；But it is to the more demanding of spring, and is once located at the lowermost disc spring pressure-bearing maximum and most holds
Easily deform, once and disc spring deforms, then need all to dismantle and realize replacements to disc spring.
Pull rod is integrated member in document disclosed above simultaneously, and when use not can be carried out length adjustment.Chinese patent
CN104089096 discloses a kind of dedicated load component that constant force branch is hung, and wraps pull rod, lower pull rod, and the upper connecting rod lower end is set
There is longitudinal counterbore, is equipped with internal screw thread in the longitudinal direction counterbore, the lower pull rod periphery is equipped with external screw thread, and upper and lower pull rod passes through spiral shell
Line links into an integrated entity, and is radially equipped with lateral first cross through hole on the hole wall of the longitudinal direction counterbore, the second cross through hole is described
The center line of first, second cross through hole is perpendicular with the center line of longitudinal counterbore, in the first, second cross through hole
Angle α is equipped between heart line, the angle α is obtuse angle；The upper end outer peripheral surface of the lower pull rod is equipped with respectively with corresponding the
One, the second cross through hole corresponding groove when connection, is inserted with cross bar, the cross in first, second cross through hole respectively
One end of bar is inserted into corresponding groove.But its is inconvenient to use, especially not applicable to be similar to one disclosed in CN101545562
Kind spring hanger.In addition it can not achieve vibration damping and can not realize and accurately fixed object.
But above-mentioned technical proposal can not achieve suspension and support in actual use and object be accurately fixed on to specified height.

Beneficial effect
Branch is realized by the confined space between vacuum chamber, pulling plate and the loading plate in rod assembly jointly in the application
Carrier under support/lifting on pull rod；Due to mainly passing through vacuum chamber bring air pressure and carrier in device really
Weight maintain an equal level, in confined space between compressed air and rod assembly and carrier the Balancing relization of strength to carrier
Support, vibration damping and other effects.
Simultaneously because the design of vacuum chamber and confined space, so that power is balance during entire support/carry, no
It will appear the phenomenon for causing the individual part service life short because of unbalance stress.
Meanwhile when suspension and support precision is inadequate, only it need to adjust the volume of confined space, be able to achieve with air pressure in vacuum chamber
Accurate positionin to carrier.
