Description

A kind of assemble method of constant-force disk spring support hanger
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.
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.
Background technique
The invention belongs to hanger fields, and in particular to a kind of assemble method of constant-force disk spring support hanger.
Summary of the invention
The present invention provides a kind of assemble method of constant-force disk spring support hanger, can be effectively controlled the elaborate position of object, together When be able to achieve adjust load pull rod length, and improve object effectiveness in vibration suppression, effectively improve the use scope of suspension and support.
To realize the above-mentioned technical purpose, the present invention take the specific technical proposal is: a kind of group of constant-force disk spring support hanger Dress method, includes the following steps:
Step 1: pulling plate to be fixed on to the upper end of upper connecting rod, and guarantee that upper connecting rod is located at the center of pulling plate；
Step 2: cylinder is inverted, by pulling plate to be parallel to cylinder body bottom, upper connecting rod be parallel to the placement of cylinder short transverse In cylinder；
Step 3: installing several disc springs into cylinder, disc spring is set on upper connecting rod in a manner of positive and negative alternate；
Step 4: opening the port of upper connecting rod, pull rod is fitted into upper connecting rod by under after the fixed sheet rubber in lower pull rod top, Until the bottom of lower pull rod reaches the top inside upper connecting rod；
Step 5: in the bottom end of cylinder, the local horizontal direction mounting dampers along cylinder bottom surface of the stretching of lower pull rod；
Step 6: overturning cylinder, cylinder is just being set, lower pull rod drops under gravity, is adjusted and is pulled up by port Vacuum degree between bar and lower pull rod realizes the positioning of lower pull rod.
As the improved technical solution of the present invention, sheet rubber is installed on lower pull rod top by the way of being embedded in, specifically Sheet rubber is equipped with for the periphery on lower pull rod top and top, and card slot is installed, it will be in the rubber fluid of the top merging melting of lower pull rod Molding obtains the lower pull rod embedded with sheet rubber.
Include each substance of following parts by weight as the improved technical solution of the present invention, in rubber fluid:
20-30 parts of natural rubber
1-3 parts of antioxidant
0.1-2 parts of fluoride resin
2-5 parts of polyurethane.
As the improved technical solution of the present invention, pulling plate is metal plate.
It further include when installing disc spring, in each disc spring in step 3 as the improved technical solution of the present invention A spring is first installed in big opening side, then carries out the installation of next disc spring again.
As the improved technical solution of the present invention, the inner wall of upper connecting rod is coated with lubricious, lubricious mainly realization The damage of more sheet rubbers is reduced, coating includes each substance of following parts by weight:
3-10 parts of silica
5-20 parts of graphite powder
2-8 parts of epoxy resin
1-3 parts of fluoride resin
