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 body of power station boiler, power station, and the place that needs this type of supporting in oil, chemical industry.Existing constant force spring hanging frame is pure mechanical structure, and during use, its load and displacement can not intuitively show, can only show roughly estimation according to pointer, can't accurately learn load and the shift value of constant force spring hanging frame, can not report to the police when system breaks down.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, constant force spring hanging frame that can intuitively show load and shift value.
The present invention is achieved by the following technical programs:
a kind of load and displacement constant force spring hanging frame that shows, comprise spring mechanism, be fixed on the fixed frame of spring mechanism upside, be arranged on slewing frame and load coupling in fixed frame, described slewing frame middle part is hinged by bearing pin and fixed frame, the slewing frame outer end is provided with shift adjusting machine, load adjustment axle and the load coupling upper end of shift adjusting machine are hinged, slewing frame is inner and the spring mechanism upper end is hinged, the load coupling comprises load screw rod and lower load screw rod, described fixed frame top is provided with displacement sensor mechanism, be provided with the load sensing mechanism between upper load screw rod and lower load screw rod, described displacement sensor mechanism comprises dunnage, be arranged on displacement transducer and the displacement display device of dunnage upside, dunnage one end is fixedly connected with fixed frame, the dunnage the other end is provided with vertical long chute, displacement transducer is connected with dunnage is removable, the displacement transducer downside is adjusted axle by steel wire with the load of shift adjusting machine and is connected, steel wire and described vertical removable connection of long chute, displacement transducer is connected with the displacement display device by datawire, the load sensing mechanism comprises load transducer, load transducer fender bracket, load display device, upper cap nut and lower nut, load transducer, upper cap nut and lower nut are separately positioned in the load transducer fender bracket, upper load screw rod lower end and lower load screw rod upper end are passed respectively the load transducer fender bracket and are fixedly connected with load transducer two ends, upper cap nut and lower nut screw respectively in upper load screw rod lower end and lower load screw rod upper end, the load transducer fender bracket is supported in upper cap nut, and load transducer is connected with the load display device by datawire.
Purpose of the present invention can also further realize by following technical measures.
The aforesaid load and displacement constant force spring hanging frame that shows is provided with gap a between wherein said lower nut and load transducer fender bracket, and gap a is 1mm～2mm.
The present invention adopts electromechanical integrated structure, set up displacement sensor mechanism and load sensing mechanism on the basis of existing constant force spring hanging frame, simple in structure, can intuitively show actual load and shift value during use, greatly improved working efficiency, when breaking down, system can report to the police, in order in time eliminate fault.
Advantage and disadvantage of the present invention will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiments only provide as an example with reference to accompanying drawing.
