Description
Technical field
The utility model relates to a kind of damper, particularly a kind of On A Retrofitted Damper that can detect in real time damper inner piston rod displacement amount and damper internal pressure.
Background technique
Damper, is the resistance that motion is provided, the device of depletion kinergety.Utilizing damping to carry out energy-absorbing damping is not any new technology, applies already various dampers (or vibration damper) and carry out damping power consumption in space flight, aviation, military project, firearms, automobile and other industries.From nineteen seventies, people start step by step these technology to be converted in the structural engineerings such as building, bridge, railway, and its development is very rapid.Particularly have five more than ten years history hydraulic pressure viscous damper, before the U.S. is accepted by structural engineering circle, experienced a great many of experiments, strictly examination, the repeatedly very long process of demonstration, particularly earthquake test.
Conventional viscous damper at present, its design is according to damping ouput force corresponding to certain speed, and its working state cannot actually obtain after dispatching from the factory, especially some risk zones, maintainer cannot directly arrive.Whether need in actual use performance and the product of understanding in real time damper normally to work, the parameter that directly can react damper performance and working state is damper piston position and internal pressure.Real-time monitoring system need to be installed, and current damper cannot be realized the obtaining signal to monitoring system.
Chinese invention patent application CN101761599 discloses a kind of MR damper of inbuilt displacement sensor, the MR damper of inbuilt displacement sensor is made up of piston, piston rod, built-in pipe and the displacement transducer of clutch release slave cylinder, the large aperture of core band, is full of magnetic flow liquid in clutch release slave cylinder; In the time that piston rod promotion piston moves in clutch release slave cylinder, when piston rod enters or deactivates the interior motion of cylinder, built-in pipe also enters or exits in the macropore of piston, because the external diameter of piston rod is identical with built-in pipe, makes the constancy of volume of clutch release slave cylinder; When piston movement, also drive the sliding axle motion that is arranged on the displacement transducer in built-in pipe, make to be arranged on the signal of the displacement transducer energy output piston real-time displacement amount in built-in pipe.But this invention can not provide the live signal of pressure, do not provide pressure how to detect yet.
Summary of the invention
The utility model technical issues that need to address are a kind of On A Retrofitted Dampers that can detect in real time displacement and pressure signal in damper.
For solving above-mentioned technical problem, novel intelligent damper of the present utility model comprises oil cylinder, piston and piston rod, described piston is arranged in oil cylinder, be left chamber and the right chamber communicating by oil cylinder interior separation, described piston rod is fixed on the two ends from oil cylinder on piston and passes, described piston has the cavity of sealing near a side of right chamber, in described cavity, be fixed with the first pressure transducer, on described the first pressure transducer, be connected with datawire, the datawire of described the first pressure transducer through piston and piston rod to oil cylinder; One end of described piston rod is fixed with displacement transducer, is also connected with datawire on described displacement transducer.
Further, described oil cylinder left end is provided with the second pressure transducer near the inside, one end of left chamber, on described the second pressure transducer, is connected with datawire.
Adopt after said structure, novel intelligent damper of the present utility model, by installation position displacement sensor and pressure transducer, is understood damper internal pressure situation of change in real time, is convenient to understand whether leakage of oil of damper, and whether seal ring is intact.Whether displacement transducer is understood damper piston in real time whether in meta, and whether deviation meets usage requirement, need to adjust etc., and these are most important to the normal work of damper.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the cross-sectional schematic of the utility model On A Retrofitted Damper.
In figure: 1 is piston rod, 2 is the second pressure transducer, and 3 is oil cylinder, and 4 is left chamber, and 5 is piston, and 6 is the first pressure transducer, and 7 is displacement transducer, and 8 is datawire, and 9 is right chamber
Embodiment
As shown in Figure 1, novel intelligent damper of the present utility model comprises oil cylinder 3, piston 5 and piston rod 1, described piston 5 is arranged in oil cylinder 3, and piston 5 is left chamber 4 and the right chamber 5 communicating by oil cylinder 3 interior separations, and described piston rod 1 is fixed on piston 5 and passes from the two ends of oil cylinder 3.Described piston 5 has the cavity of sealing near a side of right chamber 9, in described cavity, be fixed with the first pressure transducer 6, on described the first pressure transducer, be connected with datawire 8, the datawire of described the first pressure transducer is through piston 5 and piston rod 1 to oil cylinder 3, and the pressure that can detect in time in oil cylinder 3 by the first pressure transducer 6 like this changes.One end of described piston rod 1 is fixed with displacement transducer 7, on described displacement transducer 7, is also connected with datawire 8, detects in time the change in displacement of piston rod and piston entirety by displacement transducer 7.And the numerical value the first pressure transducer 6 and displacement transducer 7 being detected by datawire 8 is transferred to controller.
Working principle of the present utility model is as follows: piston is initially located in meta, and in the time being subject to External Force Acting, piston rod moves along External Force Acting direction, and resisting medium produces damping force, stops piston movement, and piston movement speed is reduced.In the time receiving External Force Acting, piston rod moves along External Force Acting direction, piston rod can drive piston to a side shifting, resisting medium in extruding or lax left and right chamber, now the pressure of the resisting medium in left chamber 4 and right chamber 9 changes, can detect damper pressure changing by the first pressure transducer, understand whether leakage of oil of damper, whether seal ring is intact.Whether meanwhile, whether understand damper piston in meta by displacement transducer 7, whether deviation meets usage requirement, need to adjust.
Further, in order to detect the pressure at piston two ends, understand the situation of change that timely piston pressure at two ends increases and reduces, be provided with the second pressure transducer 2 at described oil cylinder left end near the inside, one end of left chamber, on described the second pressure transducer 2, be connected with datawire.
Although more than described embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; can make various changes or modifications to present embodiment; and not deviating from principle of the present utility model and essence, protection domain of the present utility model is only limited by appended claims.
