Abstract
The invention discloses an anti-deflection constant-force spring support device, belonging to the technical field of pipeline transportation support. The device comprises an elastic compensation device which is located on a columnar pedestal, wherein the device is provided with a group of flat spiral springs; one ends of the flat spiral springs are relatively fixed with a shell of the elastic compensation device, and the other ends of the flat spiral springs are relatively fixed with a spindle which is supported on the elastic compensation device; two extended ends of the spindle are fixedly connected with involute sheaves, respectively; the involute sheaves are wrapped with a steel wire rope; the extended end of the steel wire rope is fixedly connected with a seat body after winding around a movable pulley; the movable pulley is supported at the lower part of a frame, the upper end of which supports load; and the frame and the pedestal form a sliding pair in the vertical direction and are restricted in the horizontal direction by a group of guide wheels which are arranged in the internal circumference. After the anti-deflection constant-force spring support device is adopted, even if the load has displacement in the horizontal direction, and the horizontal displacement also can be converted into the vertical displacement through the guide wheels without deflection, so that the safety and stability of the transport pipelines are ensured.
Description
Technical field
The invention belongs to pipeline and carry the support technology field, relate to a kind of resilient supporting unit, especially a kind of anti-deflection constant force spring support device.
Background technique
Pipelines such as electric power, oil, chemical industry are carried and are all be unable to do without the constant force spring support system.Though the displacement that all kinds of support systems can cause according to factors vary such as external temperatures, the compensating action through self spring keeps comparatively constant supporting effect power in certain accuracy rating.But, except the displacement of Vertical direction, also has the displacement of substantially horizontal because the thermal expansion of conveyance conduit is multidirectional in most situation.When bigger substantially horizontal displacement appears in pipeline, if adopt simple supporting type spring bracket owing to stressedly not on the supporting post axis deflection will take place, light then influence is supported reliably, heavy then produce catching phenomenon, conveyance conduit is broken down.
Summary of the invention
Goal of the invention: the deficiency to existing in the existing technology, the purpose of this invention is to provide a kind of anti-deflection constant force spring support device, with through architecture advances, can avoid producing Horizontal displacement and cause deflection, thereby guarantee the safety and stability of delivery line.
Technological scheme: in order to realize the foregoing invention purpose, the technological scheme that the present invention adopts is following:
A kind of anti-deflection constant force spring support device comprises the stretch compensation device that is positioned on the column bearing, and one group of plane scroll spring is housed in the said stretch compensation device; One end of said plane scroll spring and pedestal relative fixed, the other end be supported on the main shaft relative fixed on the pedestal; Two overhanging ends of said main shaft are fixed with the involute sheave respectively, are wound with wire rope respectively on said two sheaves; The overhanging end of two wire rope is connected with pedestal after walking around movable pulley respectively, and two movable pulleys are supported on the framework bottom that load is shored in the upper end to this; Said framework and said bearing constitute vertical sliding pair, and through one group of upper saw pulley formation in week in being installed in and the substantially horizontal constraint between the said bearing.
After adopting the present invention, the displacement of carrying is delivered on the wire rope through movable pulley by the up-down of framework, relends the flexible compensating action that plays that helps spiral spring.Because the stretch compensation device remains static all the time; And framework is tied that can only go up and down not can Horizontal displacement, even the therefore displacement of load with substantially horizontal also will change vertical deviation into through upper saw pulley; Therefore device deflection of the present invention not, thus guarantee the safety and stability of delivery line.
Beneficial effect: compared with prior art, anti-deflection constant force spring support device of the present invention also has following remarkable advantage except that having reliably anti-deflection effect:
The position that takes up room when 1) using is little, adapts under the various situation and installs and uses;
2) adopt plane scroll spring, cost is low, long service life;
3) the plane scroll spring combination is used, and can adapt to the different demands of various tension force;
4) cover shape structure has dustproof effect, guarantees also can normally move in the comparatively serious occasion of dust atmosphere.
Description of drawings
Fig. 1 is the structural representation of anti-deflection constant force spring support device;
Fig. 2 is the side view of anti-deflection constant force spring support device.
Embodiment
Below in conjunction with concrete accompanying drawing the present invention is done further explanation.
As depicted in figs. 1 and 2; Anti-deflection constant force spring support device comprises stretch compensation device 1; Stretch compensation device 1 is positioned on the rectangular tube column bearing 4 that is connected in base plate 8; One group of plane scroll spring is housed in the stretch compensation device 1, an end of each plane scroll spring and stretch compensation device 1 relative fixed, the other end be supported on the main shaft relative fixed on the stretch compensation device pedestal.Two overhanging ends of main shaft are fixed with respectively on involute sheave 10, the two involute sheaves 10 and respectively are wound with wire rope 12.The overhanging end of wire rope 12 is walked around movable pulley 2 backs and is connected through U-shaped hanger 9 and stretch compensation device 1.Two movable pulleys, 2 symmetric support are shored framework 5 bottoms of load through top board 7 in the upper end.This top board 7 is fixed in the framework 5 through adjustable column 6 plug-in mountings of bottom, therefore can regulate top board 7 height easily.Framework 5 is the cover shape; The enclosure is outside stretch compensation device 1; Constitute vertical sliding pair with bearing 4; And through be installed in week in its guide holder 11, respectively six upper saw pulleys 3 of four sides of corresponding rectangular tube column bearing 4 form with bearing 4 between the substantially horizontal constraint, make the framework 5 can only be, and can not be shifted towards the direction all around of horizontal plane along vertical the moving up and down of rectangular tube column bearing 4.Six upper saw pulleys 3 have two both sides that are placed in corresponding two movable pulleys 2 respectively, in addition four mutually in pairs, be placed in the in addition both sides adjacent respectively with movable pulley 2.
The present invention adopts the big displacement constant force spring compensator of said structure as the thermal walking compensating element, and wire rope 12 can increase load capacity on movable pulley 2.Framework 5 four sides adopts upper saw pulley 3 not only to see the surface friction drag when reducing to lead; Also has the effect that absorbs lateral load; Therefore depart from the support line load or during than the levels displacement, can guarantee that also this device is vertically stressed when top board 7 receives, skewness does not take place.Compared with prior art, except that having reliably anti-deflection effect, the present invention also has following remarkable advantage:
The position that takes up room when 1) using is little, adapts under the various situation and installs and uses;
2) adopt plane scroll spring, cost is low, long service life;
3) the plane scroll spring combination is used, and can adapt to the different demands of various tension force;
4) cover shape structure has dustproof effect, guarantees also can normally move in the comparatively serious occasion of dust atmosphere.
Need to prove that present embodiment only is used to explain the present invention, and nonrestrictive.With further exploration other mode of execution can also be arranged according to actual needs.
