Description
Technical field
The utility model relates to a kind of suspension bracket, and especially a kind of displacement, the constant force spring hanging frame that load is adjustable belong to the suspension and support technical field.
Background technique
Constant force spring hanging frame designs according to principle of moment balance, load moment and spring torque be balance all the time in the course of the work, to keep constant supporting force, can eliminate or reduce the additional stress to pipeline or equipment, the general place that is used for needing to reduce displacement stress, as the foil portions such as vapour, water, cigarette, airduct and burner of station boiler body, power station, and the place that needs this type of supporting in the oil, chemical industry.Load and the displacement relative fixed of existing constant force spring hanging frame, can't adjust, load can only be finely tuned by spring trimming bolt and spring-adjusting nut, the respectively corresponding multiple different load of the constant force spring hanging frame of different model and displacement like this, cause constant force spring hanging frame of a great variety, can't produce in batches and the stock, manufacture cycle is long, and in actual use, satisfying under the situation of displacement, load often need in very large range be adjusted, and existing constant force spring hanging frame can't meet the demands.
The model utility content
The purpose of this utility model provide a kind of simple in structure, be suitable for producing in batches, the constant force spring hanging frame of displacement-adjustable and then adjustable load.
The utility model is achieved by the following technical programs:
A kind of displacement-adjustable constant force spring hanging frame, comprise spring mechanism, be fixed on the fixed frame of spring mechanism upside, be arranged on slewing frame and load coupling in the fixed frame, described slewing frame middle part is hinged by bearing pin and fixed frame, slewing frame outer end and load coupling upper end are hinged, slewing frame is inner hinged with the spring mechanism upper end, described load coupling comprises load screw rod and gaily decorated basket nut, described slewing frame outer end is provided with the displacement regulating mechanism, described displacement regulating mechanism comprises load adjustment bolt, locking nut, load adjustment axle and the vertical long chute that is symmetricly set on both sides, slewing frame outer end, described load is adjusted bolt one end and is vertically passed slewing frame outer end end face, put in the slewing frame outer end, locking nut and load adjustment axle lay respectively in the slewing frame outer end, load adjustment axle screws at load and adjusts the bolt middle part, load adjustment axle two ends are bearing in respectively on the vertical long chute of both sides, slewing frame outer end, slidably be connected with described vertical long chute, locking nut screws at load and adjusts on the bolt, load is adjusted bolt fixedly connected with slewing frame.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid displacement-adjustable constant force spring hanging frame, wherein said load screw rod are fork-shaped load screw rod, and fork-shaped load screw rod upper end is hinged with load adjustment axle, and fork-shaped load screw rod lower end is connected with gaily decorated basket nut upper end.
The utility model is set up the displacement regulating mechanism in the slewing frame outer end, and is simple in structure, and according to actual needs, displacement and load can both be done significantly and adjust, and slewing frame can be produced in batches and the stock, and is with short production cycle, and cost is low.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is the left view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the utility model comprises spring mechanism 1, be weldingly fixed on the fixed frame 2 of spring mechanism 1 upside, be arranged on slewing frame 3 and load coupling 4 in the fixed frame 2, slewing frame 3 middle parts are hinged by bearing pin 5 and fixed frame 2, slewing frame 3 outer ends and load coupling 4 upper ends are hinged, it is inner hinged with spring mechanism 1 upper end, load coupling 4 comprises fork-shaped load screw rod 41 and gaily decorated basket nut 42, slewing frame 3 outer ends are provided with displacement regulating mechanism 6, displacement regulating mechanism 6 comprises load adjustment bolt 61, locking nut 62, load adjustment axle 63 and the vertical long chute 64 that is symmetricly set on both sides, slewing frame 3 outer end, load is adjusted bolt 61 right-hand members and is vertically passed slewing frame 3 outer end end faces, put in slewing frame 3 outer ends, locking nut 62 and load adjustment axle 63 lay respectively in slewing frame 3 outer ends, load adjustment axle 63 screws at load and adjusts bolt 61 middle parts, load adjustment axle 63 two ends are bearing in respectively on the vertical long chute 64 of both sides, slewing frame 3 outer end, long chute 64 front and back slip longitudinally, be convenient to regulate displacement L, locking nut 62 screws at load and adjusts on the bolt 61, load is adjusted bolt 61 fixedlys connected with slewing frame 3, prevent that load bolt 61 from coming off, it is hinged that fork-shaped load screw rod 41 upper ends and load are adjusted axle 63, its lower end screws in gaily decorated basket nut 42 upper ends, and it is hinged that load coupling 4 also can adopt other Placements and load to adjust axle 63.
As shown in Figure 2, because the payload capacity (product of displacement L and corresponding load F) of each model constant force spring hanging frame is fixed, load F and displacement L are inversely proportional to, and can adjust the load F of constant force spring hanging frame significantly by adjusting the L value, and not change the performance of constant force spring hanging frame.The L value can be set at the maximum displacement of a certain model constant force spring hanging frame, thereby covers other all displacements of this model constant force spring hanging frame correspondence, and slewing frame 3 can be produced in batches and the stock like this.
When regulating displacement L, unclamp locking nut 62, rotate load and adjust bolt 61, load adjustment this moment axle 63 is adjusted bolt 61 front and back along the vertical long chute 64 relative loads of both sides, slewing frame 3 outer end and is slided, when reaching required displacement L, locking locking nut 62 gets final product.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
