Detailed description of the invention
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail。Should be appreciated that preferred embodiment is only for illustrating the present invention, rather than in order to limit the scope of the invention。
As shown in the figure, a kind of gas chamber piston annular multi-cavity air bag pressure levelling device, including the multiple independent air bags 3 being arranged between gas chamber cylinder 1 and gas chamber piston 2, described air bag is provided with air inlet pipe 31, escape pipe 32 and turnover gas control system, and described air bag is fixed on gas chamber piston by Equipoising support apparatus。
In the present embodiment, by putting into the numerous air bag 3 with air pressure around piston, piston is implemented protection; being not intended to again the operation of piston simultaneously, and air bag contacts with barrel lateral plate and contacts into face, contact stress is only small; therefore, stability and the piston speed of service of gas chamber piston are substantially increased。
In the present embodiment, described Equipoising support apparatus includes being arranged on back(ing) bar 4 and vertical suspension rod 5, described back(ing) bar is arranged on the upper and lower sides of air bag, it is additionally provided with coil tension spring between described back(ing) bar and gas chamber piston, described vertical suspension rod is located at the air bag side relative to cylinder, the upper and lower end of described vertical suspension rod is connected with the back(ing) bar of the upper and lower side of air bag respectively, and described Equipoising support apparatus also includes the guide wheel 6 being arranged on back(ing) bar or vertical suspension rod。In the present embodiment, air bag back(ing) bar adopts coil tension spring, so, air bag can not be affected fully flexible, meanwhile, back(ing) bar adopts rubber wheel as guide wheel with vertical suspension rod junction, and this wheel can also play the effect of Anti-inclining when tilting of the piston to the limit。
In the present embodiment, described vertical suspension rod being additionally provided with rubber strip 7 and rubber strip backboard 8, described rubber strip backboard adopts metal backing。This enforcement arranges several caulking gum bands and contacts with barrel lateral plate, and in order to increase the air bag contact surface to barrel lateral plate, rubber strip backboard adopts metal backing, so rubber strip can be allowed to contact with barrel lateral plate more abundant。
In the present embodiment, being additionally provided with oil lubricating system between described gas chamber cylinder and gas chamber piston, described oil lubricating system includes thin oil bin 9, grease pump 10 and lubricating oil pipe line 11。In order to reduce the frictional force between rubber strip and barrel lateral plate, improving the speed of service of piston, the present embodiment adopts variable interval to inject the mode of rare lubricating oil, when after these rare lubricating oil streams to gas chamber base plate, irregularly it is collected, after then purifying, more back and forth uses。
In the present embodiment, described turnover gas control system includes tilt signals controller 12, leveling system controller 13 and source of the gas 14, described leveling system controller 13 respectively with tilt signals controller respectively 12 and source of the gas 14 electrically connect, described source of the gas 14 is by gas feed pipeline 15 and air bag air inlet pipe 31 UNICOM, described air bag air inlet pipe 31 is provided with gas feed and controls valve, described air bag escape pipe 32 is provided with gas outlet and controls valve, described leveling system controller controls valve with gas outlet and electrically connects, and described source of the gas controls valve with gas feed and electrically connects。
In the present embodiment, within one week, arranging several air bags at piston, each air bag taps into outlet, by controlling, is pressurizeed in tilting of the piston side, airbag aeration, and when air bag allows, air pressure is more high, and hardness is more hard, and bounce is more big, if needing piston inclined in opposite directions, as long as being discharged by the gas in the air bag in this direction, air bag is soft to get off, and piston is just leaned on over。This counter-force can be found out from figure, and as p1=p2, when piston is by being poured on left side, left side air bag is compressed, and right side air bag is stretched, and forms left and right gasbag pressure poor, and this pressure differential is exactly promote the power of piston return。Moreover, it is also possible to carry out Manual pressurizing, improve correction pressure differential。It is found through experiments, in unistage type gas chamber piston, after caulking gum film pressurized, the shape that the rubber membrane being connected with barrel lateral plate and corrugated plating is formed is exactly tire-like, after the pressurization of this arch rubber membrane air bag, just as tire, pressure is more high, bounce is more big, and this performance is just as spring。But this spring performance Radix Achyranthis Bidentatae more eager to excel in whatever one does than single spring performance, because air bag spring such as tire, is not point cantact。
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from objective and the scope of the technical program, it all should be encompassed in the middle of scope of the presently claimed invention。
