Description
Technical field
The utility model is related to a kind of temperature-compensating constant force (disc spring) suspension and supports, are especially used for the pipe of temperature change displacement
The constant hanger of the hanging of road and equipment belongs to hanger technical field.
Background technology
Currently, constant force spring hanging frame is in building etc. in industries, influence that equipment or pipeline are generated by temperature, environmental protection
Ideal damping subtract the device of offset.In particular for the bearing of electric system heat distribution pipeline, the constant force spring that pipeline is generated
Suspension and support is one kind of constant-force spring hanger, is used for various Pipe installings, some cold and hot pipelines is made to be generated in work is run
Expansion displacement and amplitude absorption and buffering, and the expansion displacement that can be limited or allow pipeline in design value, to ensure
The operational safety of pipeline and equipment.
Constant-force spring hanger is exactly to use lever principle, realizes that constant-force spring hanger generates displacement in pipe expansion
When, power of the load change rate within 5% is imposed to pipeline, to support or suspend in midair pipeline.Existing variable constant force spring
Since the required precision to constant force spring is high, spring is difficult to reach preferable precision, therefore constant force spring hanging frame hanger with control
Performance be difficult to control.
Spring temperature-compensating hanger is mainly made of cylindrically coiled spring and lever mechanism.Due to its spring and element
Manufacturing process is simple, ripe, properties of product stabilization, good economy performance, at home by prolonged application, therefore is most widely used at present
Pattern.
Utility model content
Technical problem to be solved in the utility model provides a kind of constant-force spring hanger, simple in structure, production cost
Low, service life is long, and safe operation is reliable.Damping is good, has comparable leakproofness, humidity, corrosion resistance strong.
Technical solutions of the utility model are：A kind of temperature-compensating hanger, including shell, lower cover, lower sunpender, disc spring, shell
Body is cylindric, and the upper surface of cylinder shell plate is closed one sleeve of fixed formation with shell, and lower cover and shell surround a cavity,
The area of lower cover be less than housing cavity and in shell air-tightness sliding, disc spring passes through the lower surface in a steel cylinder and shell
Fixed, disc spring lower part is fixed by the upper surface of a steel cylinder and lower cover；The upper plane of housing upper face plate is connected with platform sling, platform sling
On be provided with hole for hoist, lower sunpender is fixed on lower cover.
Further, disc spring is multilayer cascaded structure, and series connection one disc spring of disc spring topmost passes through in a steel cylinder and shell
Lower surface fix, series connection disc spring one disc spring of lowest part fixed by the upper surface of a steel cylinder and lower cover；Cylinder shell
The tail end margin of inner cavity is equipped with the stopper slided to lower cover.
The application use butterfly spring (tab (s) spring) constant hanger, disc spring to the sensitive feature of temperature performance can constant force hang
The precision of frame is high, and suspension centre is close to heat distribution pipeline under constant hanger, and tab (s) spring is heated slightly to relax, when to the cold tab (s) spring by
Cold recovery original state is shunk.The application is put forward for the first time the constant supporting spring hanger of pulling force disc spring structure, and structure is more simple, and pulling force precision
It is easier to control.
Advantageous effect：When the utility model at work, connecting rod stress directly uses pulling force, and does not have to compressing force, draws
Bring corresponding displacement, required load and pulling force constant force spring corresponding displacement directly proportional after power constant force spring.Tab (s) spring is heated to be omited
Have relaxation, pulling force is bigger, when to the cold the reinstatement that is cooled of tab (s) spring shrink, pulling force is smaller.The utility model is permanent using heat
Power spring has excellent damping, can bear prodigious load, and good airproof performance has stronger humidity and corrosion resistance,
The vibration that foreign impacts and constant force tab (s) spring itself generate when reducing work reduces the influence that constant force spring itself generates, subtracts
The slow impact that the equipment connected on connecting rod is generated, to increase the service life of equipment and this suspension and support.
Description of the drawings
Fig. 1 is the structural schematic diagram of the constant force tab (s) spring support hanging frame of the utility model.
Specific implementation mode
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
As shown in Figure 1, constant-force spring hanger, it includes：Platform sling 1, disc spring (tab (s) spring) 2, steel cylinder 3,7, lower cover
4, lower sunpender 6, shell 8, top panel 5.
Spring 2, steel cylinder 3,7, lower cover 4 are arranged in shell；Shell is cylinder shell.Temperature-compensating hanger, including
Shell 8, lower cover, lower sunpender, spring, lower cover and shell surround a cavity, the area of lower cover be less than housing cavity and
The sliding of air-tightness in shell, shell are cylinder shells, and the upper surface of cylinder shell plate 5 is closed one set of welding mast with shell
Shape；The lower plane of shell upper plate and the upper plane of lower cover directly fix tab (s) spring by steel cylinder, and the diameter of steel cylinder is slightly less than
The diameter of fixed tab (s) spring；Several steel cylinders are fixed on tab (s) spring, and the upper plane of housing upper face plate is connected with platform sling, platform sling
On be provided with hole for hoist, lower sunpender is fixed on lower cover, and the tail end margin of cylindrical shell intracoelomic cavity, which is equipped with, slides lower cover
Dynamic stopper is not drawn into figure, and stopper has two to three pieces to be mounted in the lower end on the inside of cylinder, can be after finished product installs
Installation.
The structure of the utility model is extremely simple, and the platform sling 1 with hole for hoist is provided on the upper cover plate 5 of housing unit,
Facilitate lifting；There is heat distribution pipeline load on lower sunpender, has pulled tab (s) spring.The utility model uses tab (s) spring, has
Excellent damping bears prodigious load, the vibration that foreign impacts and tab (s) spring itself generate when can reduce work, increases
The service life of oil (gas) filling device and this suspension and support, and in a humidity environment use when constant force spring performance be unaffected.
The hanger of the utility model design can make offset 100mm or more, withstand forces 50kN or more.
Particular embodiments described above, the technical issues of the utility model is solved, technical solution and advantageous effect into
Further description is gone, the foregoing is merely specific embodiment of the utility model, are not limited to this practicality
Novel, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should be included in
Within the scope of protection of the utility model.
