Description
Technical field
This utility model relates to a kind of constant force spring hanging frame, for pipeline and the hanging of equipment.Belong to hoisting appliance technical field.
Background technology
Pipeline or equipment are in running; owing to thermal expansion can make it produce certain displacement; when displacement is bigger; need to select constant force spring hanging frame to offset this partial dislocation amount; and load is controlled in a constant range; avoid bringing down additional stress to pipeline or equipment, thus protect the safe operation of whole system.Although current available all kinds of constant force spring hanging frame principles are different, but there is a general character: the installation dimension of constant force spring hanging frame vertical direction depends on the displacement of suspension bracket, the installing space thus resulting in constant force spring hanging frame is limited, particularly, in the case of pipeline or equipment displacement are relatively big, just cannot select suitable constant force spring hanging frame.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of small volume large displacement constant force spring hanging frame, this kind of constant force spring hanging frame can be greatly lowered the requirements of installation space on vertical direction.
The purpose of this utility model is achieved in that
A kind of small volume large displacement constant force spring hanging frame, it is characterized in: it includes spiral cone pulley, step pulley shaft, outer sleeve assembly, fixing axle, internal tooth wheel assemblies and cylinder torsionspring, steel wire rope is arranged in the spiral grooves of spiral cone pulley, one end of steel wire rope is fixed on spiral cone pulley, the other end downwardly extends for connecting lifting part, one end of step pulley shaft is connected with spiral cone pulley, engage for internal gear between described internal tooth wheel assemblies and step pulley shaft, described internal tooth wheel assemblies is around solid System of Rotating about Fixed Axis, described cylinder torsionspring is arranged on outer sleeve assembly, one end of cylinder torsionspring is fixed at the end plate of outer sleeve assembly, the other end is connected with internal tooth wheel assemblies.
This utility model one small volume large displacement constant force spring hanging frame, also includes lockplate, and lockplate is arranged on the other end of step pulley shaft, and is positioned at the outside of outer sleeve assembly, and lockplate is adopted with outer sleeve assembly end plate and is tightened by bolts.
Compared with prior art, the beneficial effects of the utility model are:
This utility model one small volume large displacement constant force spring hanging frame, use inside engaged gear as drive mechanism, and by the Archimedian screw groove on spiral cone pulley, the constant output load that the moment of cylinder torsionspring is converted in outer steel cord, departing from conventional slewing frame formula and the principle of major-minor spring force balanced type, the volume of mechanism is significantly reduced, can be applicable to displacement compared with big but that installing space is compact suspension centre.

Detailed description of the invention
nullSee Fig. 1-2，This utility model relates to a kind of small volume large displacement constant force spring hanging frame，It includes steel wire rope 1、Spiral cone pulley 2、Step pulley shaft 3、Outer sleeve assembly 4、Fixing axle 5、Internal tooth wheel assemblies 6、Cylinder torsionspring 7 and lockplate 8，Step pulley shaft 3 is positioned on the axial line of spiral cone pulley 2，Fixing axle 5 is positioned on the axial line of outer sleeve assembly 4，Fixing axle 5 is parallel with step pulley shaft 3，Spiral cone pulley 2 is positioned at the positive basifacial of outer sleeve assembly 4 and is connected with step pulley shaft 3，Described steel wire rope 1 is arranged in the Archimedian screw groove of spiral cone pulley 2，One end of steel wire rope 1 is fixed on spiral cone pulley 2，The other end downwardly extends for connecting lifting part，Described spiral cone pulley 2 coordinates for involute spline between step pulley shaft 3，Described internal tooth wheel assemblies 6 is perpendicular with step pulley shaft 3，And engage for internal gear between the two，Described cylinder torsionspring 7 is arranged on outer sleeve assembly 4，One end of cylinder torsionspring 7 is fixed at the end plate of outer sleeve assembly 4，The other end is connected with internal tooth wheel assemblies 6，Described internal tooth wheel assemblies 6 rotates around fixing axle 5，Coordinate for involute spline between step pulley shaft 3 with lockplate 8，After constant hanger debugging，Lockplate 8 is adopted with outer sleeve assembly 4 end plate and is tightened by bolts.
Operation principle:
Lifting part pulls downward on steel wire rope 1, spiral cone pulley 2 drives step pulley shaft 3 to rotate, owing to step pulley shaft 3 engages for internal gear with internal tooth wheel assemblies 6, step pulley shaft 3 drives internal tooth wheel assemblies 6 to rotate about fixing axle 5, and the rotation of internal tooth wheel assemblies 6 makes cylinder torsionspring 7 produce moment.
When spiral cone pulley 2 rotates, steel wire rope 1 linearly increases with the distance at step pulley shaft 3 center, during internal tooth wheel assemblies 6 and then synchronous rotary, the moment that cylinder torsionspring 7 produces the most linearly increases, when the moment that the moment that cylinder torsionspring 7 produces and lifting part produce is offset, constant force spring hanging frame is in poised state, adjusts parameter consistent to both linear preservers, can show that the load of steel wire rope outfan is steady state value.
