Fig. 2 is the part exploded view of details of the actuator of Fig. 1;
Fig. 3 is according to the present invention and comprises the schematic diagram of equipment of the actuator of Fig. 1.
The specific embodiment
With reference to the accompanying drawings, the hydraulic actuator that is used for door shown in Figure 1 represents with 10 that totally comprise two relative actuating cylinders 11,12, described actuating cylinder is axially aligned and stretched out relatively from centerbody.Output pinion 14 stretches out from centerbody 13 tops, according to no longer in mechanism's (being generally rackwork) of the as well known to those skilled in the art and easy imagination of this demonstration or description, by the rotation of hydraulic cylinder control output pinion 14 at both direction.Actuator is used for imbedding suitable recess so that pinion is connected suitably with the door that will be moved generally.
Figure 2 illustrates the decomposition view of encoder ring around the pinion zone.As shown in the figure, pinion is passed in the closing lid 17 of the seat in the centerbody 13, and pinion terminates as with the motion of being controlled by two cylinders and is connected.Under relevant situation, pinion for example has the gear 18 that connects tooth bar, and unshowned tooth bar is moved by hydraulic cylinder.
In the embodiment shown, encoder comprises by tooth 20 and is connected to dish 19 on the pinion that described tooth makes dish 19 be integral with pinion when rotated.Dish is received in the suitable housing 21, tightens on lid 17, tegmentum 22 closures up again.Encoder comprises the sensor device 23 that is used for 19 rotations of detection dish.The character of sensor device depends on the technology that is used for 19 rotations of detection dish.In a preferred embodiment, encoder is a magnetic type, because dish is suitable for being magnetized and sensor device is the checkout gear that is used to detect the changes of magnetic field that is caused by disc spins.
The periphery of dish can be provided with radial teeth 24, and it is by being detected by sensor device.Under the situation of magnetic sensor, tooth is magnetized.Interchangeable, the periphery of dish can be level and smooth or be shaped in addition.
Sensor device preferably for example forms the incremental encoder that not only can detect the pinion amount of exercise but also can detect the direction of motion, expects easily as those skilled in the art.
As among Fig. 2 well shown in, housing 21 has outside connection seat 25 at sidepiece, be used for connecting sensor device removably, described sensor device preferably is contained near the head end of connector shape case 26 in the connector shape case 26, faces with each other in the periphery of coiling when connecting with seat 25 with the head of convenient case 26.
For the correct position during connector 26 is kept being present, but the mutual locking device that between connector and seat, has buckle to remove.Advantageously, this locking device comprises the elastic tongue piece 27 that is connected with corresponding tooth 28.Tooth can be first to be positioned on the case and tongue piece can be positioned on the seat, and vice versa.
Therefore under the situation of sensor fault, the removal of sensor and replacing are fast and are easy to.
Schematically show the equipment that is used for moving door that is referred to by 30 integral body in Fig. 3, it comprises actuator 10.Described equipment comprises hydraulic pump 31, and it has electric drive motor 32 and supplies with fluid for described actuating cylinder 11,12.This realizes that by self known hydraulic circuit 36 this hydraulic circuit is provided with suitable one way valve and flap valve, thereby is supplied to and another cylinder is discharged according to cylinder of motor direction of rotation, and vice versa.Fluid is taken from suitable case 33.
The pump motor comes electric control by electronic-controlled installation 34, and electronic-controlled installation 34 receives from the positional information of encoder and other command information 35 (open/close, braking etc.).Control device preferably has the system of the microcontroller of suitable programmed.Found that advantageously the pump motor is d.c. motor (a for example 24V d.c. motor), it is controlled by feeding back by control device based on the positional information that is received by encoder.Thus, door can be controlled as and have accurate favourable acceleration and deceleration slope.Compare with alternating current motor/pump unit, d.c. motor can move under higher rotating speed, thus having reduced with respect to the loss of the volumetric loading of gross efficiency.
And, because encoder under the situation that does not need the machinery metering, can easily be set termination and middle braking point.When mobile, control device 34 can detect failure condition at once under the situation of obstruction is arranged, because the positional information that is provided by encoder has error ground directly to show the deceleration of pinion or stops suddenly.
How to realize purpose of the present invention about this point is very clear.
By control braking point or deceleration starting point and the resistance to compression security function that collapses, be applied directly to the angle that encoder on the outlet axis of automatic device makes it possible to accurately to control automatic device and move.
In fact, encoder makes that under the help that does not have servicing unit braking point or deceleration slope starting point accurately can repeatedly be discerned and be kept.In addition, by the feedback that provides, carry out the angular movement of automatic device more accurately.The precision that reads that is applied directly to the encoder of outlet on the axis is not subjected to the influence of error in the motion effective accuracy or middle clearance and meets safety standard.
Very big simplification is arranged in the use and help installation, maintenance and reparation.Encoder can be by software administration, and software is managed initial setting up (for example by self study) automatically and kept this setting.The quick connector structure makes encoder not having very rapidly replacing or reparation under the situation of instrument.
Because principle of the present invention, automatic device drives very big flexibility.Simple and the cheap control of d.c. motor band encoder feedback (easily realizing by regulating supply voltage) makes how the size and the weight of door all obtain desired only hydraulic pressure.
Therefore, might optimize a management of startup/deceleration transition and install faster, because the system compensation step is more immediately for example to meet the impact curve by the industry security standard code.
Naturally, the description of the embodiment of above-mentioned application innovative principle of the present invention only provides in the mode of example, therefore should not be considered to the restriction to patent right scope required for protection.For example, although in a preferred embodiment, encoder is a magnetic type, because it is not to the dust sensitivity, can use the encoder of optical type, therefore coil 19 and can make phonic drum etc., form sensor device, expect easily as those skilled in the art by photodiode and phototransistor or equivalent elements.
