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 support technology field, relate to a kind of resilient supporting unit, especially a kind of anti-deflection constant force spring support support arrangement.
Background technique
The pipelines such as electric power, oil, chemical industry are carried and are all be unable to do without constant force spring support system.Although the displacement that all kinds of support systems can cause according to factors vary such as external temperatures by the compensating action of self spring, keeps comparatively constant supporting effect power in certain accuracy rating.But because the thermal expansion of conveyance conduit is multidirectional in most situations, except the displacement of Vertical direction, also has the displacement of substantially horizontal.When there is larger substantially horizontal displacement in pipeline, if adopt simple supporting type spring bracket, due to stressed, not on supporting post axis, will there is deflection, light impact is supported reliably, heavy produce catching phenomenon, conveyance conduit is broken down.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the object of this invention is to provide a kind of anti-deflection constant force spring support support arrangement, with by 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 foregoing invention object, the technical solution used in the present invention is as follows:
An anti-deflection constant force spring support support arrangement, comprises the stretch compensation device being positioned on column bearing, and one group of plane scroll spring is housed in described stretch compensation device; One end of described plane scroll spring is relative with pedestal fixing, and the other end is relative fixing with the main shaft being supported on pedestal; Two overhanging ends of described main shaft are fixed with respectively involute sheave, on described two sheaves, are wound with respectively wire rope; The overhanging end of two wire rope is connected with pedestal after walking around respectively movable pulley, and two movable pulleys are supported on the framework bottom that load is shored in upper end to this; Described framework and described bearing form vertical sliding pair, and retrain by being arranged on one group of upper saw pulley formation in interior week and the substantially horizontal between described bearing.
Adopt after the present invention, the displacement of carrying is delivered on wire rope by movable pulley by the lifting of framework, relends the flexible compensating action that plays that helps spiral spring.Because stretch compensation device remains static all the time, and framework be tied can only lifting can Horizontal displacement, even if therefore load has the displacement of substantially horizontal, also will change vertical deviation into by 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 support arrangement of the present invention, except having reliable anti-deflection effect, also has following remarkable advantage:
1) position that takes up room while using is little, adapts in various situations and installs and uses;
2) adopt plane scroll spring, cost is low, long service life;
3) plane scroll spring is used in combination, and can adapt to the different demands of various tension force;
4) hood-like structure has dust-proof effect, guarantees also can normally move in the comparatively serious occasion of dust atmosphere.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-deflection constant force spring support support arrangement;
Fig. 2 is the side view of anti-deflection constant force spring support support arrangement.
Embodiment
Below in conjunction with concrete accompanying drawing, the present invention is described further.
As depicted in figs. 1 and 2, anti-deflection constant force spring support support arrangement 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 stretch compensation device 1, one end of each plane scroll spring is relative with stretch compensation device 1 fixing, and the other end is relative fixing with the main shaft being supported on stretch compensation device pedestal.Two overhanging ends of main shaft are fixed with respectively on involute sheave 10, two involute sheaves 10 and are respectively wound with wire rope 12.After the overhanging end of wire rope 12 is walked around movable pulley 2 and by U-shaped hanger 9 and stretch compensation device 1, be connected.Two movable pulley 2 symmetric support are shored framework 5 bottoms of load by top board 7 in upper end.This top board 7 is fixed in framework 5 by adjustable column 6 plug-in mountings of bottom, therefore can regulate easily top board 7 height.Framework 5 is hood-like, the enclosure is outside stretch compensation device 1, form vertical sliding pair with bearing 4, and by be arranged on interior week of its guide holder 11, respectively six upper saw pulleys 3 of four sides of corresponding rectangular tube column bearing 4 form and bearing 4 between substantially horizontal retrain, make the framework 5 can only be along vertical the moving up and down of rectangular tube column bearing 4, and can not be towards the displacement of direction all around of horizontal plane.Six upper saw pulleys 3 have two both sides that are placed in respectively corresponding two movable pulleys 2, another four mutually in pairs, be placed in respectively the another both sides adjacent with movable pulley 2.
The present invention adopts the large displacement constant force spring compensator of said structure as thermal walking compensating element, and wire rope 12, on movable pulley 2, can increase load capacity.Surface friction drag when framework 5 four sides adopt upper saw pulley 3 not only to see to reduce to lead, also there is the effect that absorbs lateral load, therefore when top board 7 is subject to departing from support line load or larger Horizontal displacement, also can guarantee that this device is vertically stressed, skewness does not occur.Compared with prior art, except having reliable anti-deflection effect, the present invention also has following remarkable advantage:
1) position that takes up room while using is little, adapts in various situations and installs and uses;
2) adopt plane scroll spring, cost is low, long service life;
3) plane scroll spring is used in combination, and can adapt to the different demands of various tension force;
4) hood-like structure has dust-proof effect, guarantees also can normally move in the comparatively serious occasion of dust atmosphere.
It should be noted that, the present embodiment is only for explaining the present invention, and nonrestrictive.Can also there is other mode of execution with further exploration according to actual needs.
