Description
Technical field
Spring support hanging frame is designed according to principle of moment balance, in the range of defined load displacement, 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 supporting can be obtained
Power, additional stress will not be carried out to pipeline and equipment belt.Perseverance, which is hung, to be generally used for needing the place for reducing displacement stress, such as station boiler
The foil portion such as body, vapour, water, cigarette airduct and the burner in power plant, and petrochemical equipment and it is other need reduce position
Move the place of stress.
In practical application such as：Point of suspension in tracheae, water pipe and the oil of Thermal Power Station, the pipe-line system of chemical industry
Thermal walking it is very big, up to several millimeters, tens millimeters to hundreds of millimeters, if using common suspension apparatus, suspension apparatus is born
Load by be normal load several times more than, be suspended pipe-line equipment will gross distortion, bring very big additional stress, sternly
Ghost image rings the safety of pipe-line equipment and the equipment safety in whole power station, in order to avoid pipe-line system produce 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, remain to keep permanent
Determine the Suspenoing apparatus of supporting force, this equipment is referred to as constant supporting spring hanger, and then constant hanger is widely used, constant force branch
Suspension bracket is the important auxiliary of steam power plant, and its performance directly influences steam power plant security, reliability, Nai Zhiying
Ring the economic development to China.
The stability in suspension and support to use how is improved, is always the Main way of research.In the prior art in order to carry
The stability of high suspension and support under vibration；The patent No. 02138291.3, entitled " no spring pull bar dual AC power framework disk spring
The patented technology of suspension and support ", a kind of suspension and support formed using disc spring and power switching mechanism is disclosed, is become to adapt to load
Change, change load-carrying ability by adjusting tensioned power.In the patent, spring carries the power for being carried in input completely；

Tightening nut in power switching mechanism lower end, be provided with 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.Disc spring in other disc spring group is the edge by disc spring
Stress is carried out, disc spring edge easily deforms or fissioned during use.
Pull bar is integrated member in document disclosed above simultaneously, can not carry out length adjustment during use.Chinese patent
CN104089096 discloses the dedicated load component that a kind of constant force branch is hung, and wraps pull bar, lower pull bar, and the upper connecting rod lower end is set
There is longitudinal counterbore, be provided with internal thread in longitudinal counterbore, the lower pull bar periphery is provided with external screw thread, and upper and lower pull bar passes through spiral shell
Line is linked into an integrated entity, and horizontal first cross through hole is radially provided with the hole wall of longitudinal counterbore, and 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 first, second cross through hole
Angle α is provided between heart line, the angle α is obtuse angle；The upper end outer peripheral face of the lower pull bar is provided with respectively with corresponding the
First, the corresponding groove of the second cross through hole, during connection, cross bar, the horizontal stroke are inserted with respectively in first, second cross through hole
One end of bar is inserted in corresponding groove.But itself in-convenience in use, it is especially inapplicable to be similar to one disclosed in CN101545562
Kind spring hanger.It can not realize that vibration damping can not be realized in addition accurately to be fixed object.
But above-mentioned technical proposal can not realize that object is accurately fixed on the height specified by suspension and support during actual use.
Background technology
The invention belongs to suspension bracket field, and in particular to a kind of constant-force spring hanger.
The content of the invention
