Background technique
Magnetic flow liquid is the novel intelligent material that a kind of rheological properties controls by externally-applied magnetic field, under the effect of externally-applied magnetic field, be the plastomer of similar solid by the fluid transforms that mobile performance is good and present solid mechanics character, once remove externally-applied magnetic field magnetic flow liquid to recover again the good fluid of mobile performance, this reversible controlled excellent rheological properties makes it be widely used in the mechanical fields such as buffer, damper, break.
At present, Coal Exploitation is used in Liquid and gas damper that coal plough uses primarily of compositions such as cylinder block, cylinder body, piston, pressure relayes; The planer head of coal plough will rely on Liquid and gas damper to carry out retarding braking when walking to head or tail, gas in main extruding cylinder body and machine oil realize braking, it is not steady at present to there is braking process in this buffer, damping force is little, the excessive destruction of easily causing cylinder block and cylinder body of impact force due to coal plough, require higher to seal arrangement, constantly change obturator, these all may affect the manufacturing efficiency of coal plough simultaneously.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides magnetic flow liquid Liquid and gas damper, effectively can improve stationarity and the damping force of coal plough braking process, extends the cylinder body life-span simultaneously, reduce the maintenance that Liquid and gas damper seal request reduces obturator, be easy to intelligent control.
To achieve these goals, the technical solution adopted in the utility model is: a kind of magnetic flow liquid Liquid and gas damper mainly comprises: magnetorheological damping bar, seal ring, front cover, cylinder body, magnetic flow liquid gap, coil, sleeve, piston, bolt, seal ring, pressure transducer etc.Wherein cylinder body is divided into oil cylinder and cylinder two-part, magnetorheological damping bar right-hand member embeds with piston rod and is connected, magnetorheological damping bar right-hand member is with shearing ring, coil is assemblied in sleeve and forms Spielpassung with piston rod, Piston assembling is in the cylinder cavity of cylinder body, when working to the right, pressurized gas provides resistance, and pressure transducer is arranged on the bottom of cylinder body, test gas pressure data.
Preferably, embed with piston in the oil cylinder chamber of magnetorheological damping bar installation cylinder body and be connected, the shearing ring outer shroud of its right-hand member and cylinder body form magnetic flow liquid gap, and inner ring and sleeve also form magnetic flow liquid gap, can provide the damping force of twice during work.
Preferential, the right-hand member of cylinder body oil cylinder cavity segment is that the magnetic flow liquid gap formed with the shearing ring of magnetorheological damping bar right-hand member of taper diminishes gradually, and the damping resistance of generation is increasing.
Preferential, pressure transducer is arranged on the bottom of cylinder body, test gas pressure data is controlled the power supply size of external power supply cut-out and coil, the driving power of coal plough is just cut off when the pressure of gas reaches certain numerical value, connect the power supply of electromagnetic coil simultaneously, generate an electromagnetic field in magnetic flow liquid gap, make magnetic flow liquid work.
Beneficial effect of the present utility model: the utility model provides magnetic flow liquid Liquid and gas damper, traditional Liquid and gas damper, it mainly extrudes gas in cylinder body and machine oil realizes braking, it is not steady to there is braking process in this buffer, damping force is large not, shearing ring outer shroud and the cylinder body of its right-hand member of magnetorheological damping bar of magnetic flow liquid Liquid and gas damper of the present invention form magnetic flow liquid gap, inner ring and sleeve also form magnetic flow liquid gap, can provide the damping force of twice during work, damping force is large; Its damping force is also increase along with the minimizing of working clearance, so braking steadily; Owing to mainly relying on the damping friction dynamic braking of magnetic flow liquid, so reduce Liquid and gas damper seal request, reduce the maintenance of obturator, extend the cylinder body life-span; Magnetic flow liquid braking is easy to intelligent control in addition.
