Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Embodiment 1
A kind of anti-rollover groove tank car, as shown in Figure 1 and Figure 2, the first half of tank body is connected by hinge 103 and chassis of vehicle body, and the latter half of tank body is connected by hinge and hydraulic actuating cylinder and rear schedule transverse axis; All have two single-acting plunger type hydraulic cylinders 107 in the both sides of tank body, the flexible swing that can allow tank body that certain amplitude occurs to both sides of hydraulic actuating cylinder 107, reaches the object of balance vehicle body.Be mounted with Servocontrol device 101 in the foremost of tank body, it can monitor oneself state hydraulic control system in real time in car body is advanced, and regulates the balance of car body.
As shown in Figure 3, unidirectional fix-displacement pump 206 is delivered to the electrohydraulic servo valve 202 of a pair interlocking to hydraulic efficiency pressure system through transport pipe from fuel tank Extract force feed; When the electrohydraulic servo valve 202 that meta mechanism is " K " type is in off-position, hydraulic oil is communicated with plunger-type cylinder 201 and back pressure valve 207 by transport pipe simultaneously, finally return fuel tank, check valve 203 is provided with between electrohydraulic servo valve and back pressure valve, so just can ensure that the hydraulic actuating cylinder oil circuit of groove tank body both sides, place is not ganged up, thus make hydraulic actuating cylinder when static, still can have the balance of certain pressure retention groove tank body.When one of them electrohydraulic servo valve energising work, another is in off-position.The plunger-type cylinder that the side electrohydraulic servo valve of energising is corresponding makes its plunger stretch out under the effect of pressure oil, tank body is rotated to opposite side, force the plunger hydraulic cylinder plug at opposite side to it in shrink and extrude hydraulic oil and return fuel tank by transport pipe through back pressure valve 207.
Car body balance Servocontrol device principle as shown in Figure 3, control setup part is primarily of micro controller system and tandem circuit thereof and gravity pendulum composition, wherein gravity pendulum is connected by a pair internal gear pair and elastic conduction reed, such internal gear, to amplifying the swinging signal of gravity pendulum, improves the susceptibility of system response.Carrying capacity in the velocity magnitude of the traveling of car body, groove tank reaches the inside of micro controller system by the mode of serial communication.When inclination, car body going direction changing, gravity pendulum can force the elastic conduction reed 303 of ground connection to come in contact with conductive pole 302 by the gear mesh of a pair internal messing under gravity, centrifugal action, conductive pole terminals 21 ' and 22 ' are connected to pull-up circuit and are connected to the corresponding I/O mouth of micro controller system respectively, I/O mouth level state is changed, is arrived by microprocessor detect.When evenness of road surface does not change without inclination, velocity reversal, elastic conduction reed 303 does not contact with conductive pole, and single-chip processor i/o mouth state keeps.
By to mcu programming, electrohydraulic servo valve electrical condition is controlled in real time, the stroke of adjustable column plug cylinder plunger, thus reach the object regulating car body balance.When tilting to different directions/turn, elastic conduction reed 303 contacts the conductive pole of not homonymy respectively, thus makes the hydraulic actuating cylinder action of corresponding side, illustrates below:
The equilibrium principle that groove tank car travels on tilted road surface as shown in Figure 5, in car body travels on straight nonangular road (in), gravity pendulum pointer is in the center position of dial plate, elastic conduction reed can not touch conductive pole contact, hydraulic actuating cylinder keeps original stroke, and car body balance travels.During blocking the way road direction right bank, the left side (left side) of gravity pendulum pointer deflection dial plate, because the conductive pole contact on elastic conduction reed and the right comes in contact.Servocontrol device, according to after obtained signal synthesis process, controls the electrohydraulic servo valve energising of supervisor right side hydraulic actuating cylinder, and right side cylinder plunger is stretched out, and tank body moves to the left, thus reaches a new equilibrium point.During blocking the way road direction left side, action contrary each assembly makes tank body occur to be tilted to the right with road during by cooperatively interacting.
Groove tank car change without velocity reversal on tilted road surface travel time equilibrium principle as shown in Figure 6, car body keep straight on time (in), gravity pendulum pointer is in the meta of dial plate, cylinder plunger attonity, car body balance travel.When car body turns left (left side), gravity pendulum swings to the right under the influence of centrifugal force, is contacted by internal gear to making elastic conduction reed 303 with the conductive pole contact 302 on the right simultaneously.Now, Servocontrol device, will the electrohydraulic servo valve energising of supervisor right side hydraulic actuating cylinder according to after obtained signal synthesis process, and right side cylinder plunger is stretched out, and tank body moves to the left, thus reaches a new equilibrium point.When car body is turned right, action contrary each assembly makes tank body occur to turn left with car body during by cooperatively interacting.
Be presented above a kind of concrete embodiment, but the present invention is not limited to described embodiment.Basic ideas of the present invention are following scheme:
Anti-rollover groove tank car, car body and groove tank hinged, hinge axes, along car body bearing of trend, is provided with driver train between car body and groove tank, this driver train be used for adjustment tank tank rotate along described hinge axes.Groove tank rotates along hinge axes, thus can adjust in real time car body state, avoids rollover to occur.
Based on above-mentioned basic scheme, can numerous embodiments be formed:
● the employing as embodiment 1 regulates left and right hydraulic cylinder extension length to carry out the swing of driver slot tank; As other embodiments, also can adopt other type of belt drive, as driven groove tank to swing by driving twisted axis to rotate.As speed reduction gearing is installed in groove tank front end or rear end, speed reduction gearing drives twisted axis to rotate; By motor drive deceleration mechanism.
● except the hydraulic power form in embodiment 1, can also aerodynamic force be adopted, the power form such as electric power.
● the support in embodiment 1 is used for connection body and groove tank, and realizes the hinged of car body and groove tank; As other embodiments, also can substitute by other exchanging structures.Triangular supports in embodiment 1 is certain height by the lifting of groove tank, is conducive to swinging of groove tank.
● the quantity of hydraulic actuating cylinder also can adjust, as groove tank front end, rear end all arrange hydraulic actuating cylinder.The advantage of embodiment is, only rear end arrange can either simplified structure, cost-saving be also convenient to control.
● in order to detect inclined degree, be not limited to the gravity pendulum in embodiment 1.Adopt the advantage of gravity pendulum to be that gravity pendulum not only can indicate inclined degree, centnifugal force size during turning can also be indicated.Detecting and centnifugal force size detection to realize inclined degree, can dissimilar sensor be adopted respectively realize.
● about mode, just understand trigger controller when the swing of gravity pendulum acquires a certain degree in embodiment 1, the control of controller to hydraulic gear has certain time delay.As other embodiments, also can adopt the mode controlled in real time, as adopt angular transducer or other can detect the sensor of car body inclined degree, according to the amount of spin of the real-time control driver train of the difference of inclined degree.
For those of ordinary skill in the art, according to instruction of the present invention, designing the model of various distortion, formula, parameter does not need to spend creative work.The change carried out embodiment without departing from the principles and spirit of the present invention, amendment, replacement and modification still fall within the scope of protection of the present invention.
