Abstract

PURPOSE:To stop rotary motion of a rotary actuator immediately when necessary, by pressing a press member always through spring tension and advancing the press member in accordance with a decrease of oil pressure. CONSTITUTION:If working oil at normal operation time is supplied, a press member 1 is forcibly returned against a belleville spring 2. If supply of the working oil is reduced by power interruption, fault, etc., the press member 1 is pressed by the spring 2, and a protruding part 9 presses a holder spring 8, then the spring 8 is pressed to a rotor shaft 12, accordingly rotary motion of the shaft 12 is immediately stopped.

The present invention is always pressed with spring pressure, but while a constant hydraulic pressure is supplied, a suppressor is provided that maintains the state of being pushed back against the spring pressure, and the suppressor is used to reduce the hydraulic pressure. This is a rotary actuator stopping device characterized in that it stops the operation of a μm tally actuator by moving forward in accordance with the movement of the rotary actuator, and the drawings show an embodiment thereof. In the figure, A is a device according to the present invention, and B is a rotary actuator to which this device is connected, and the model is not particularly limited. The rotary actuator B shown in the figure is the most sealless type This is a basic model. In the figure, 1 is a bowl-shaped suppressor with an opening in the center, into which a disc spring 2'a' is fitted. 3 is a cylinder into which the presser 1 is fitted, and its inner wall Pedestal part 4 for stopping the press body 1
form. Reference numeral 5 denotes an oil port, which is arranged in the same hydraulic circuit as the oil port in rotary actuator B, which will be described later. 6 is an end cover that closes the end of the cylinder 3. Numeral 7 denotes bolts for connecting to the AV rotary actuator B of this device, and several bolts are threaded from the end cover 6 through the cylinder 3 to the cylinder 11 of the four-tary actuator B. A holder spring 8 is fitted into a recess formed in the base portion 4. This holder spring 3 is pressed by a convex portion 9 formed on the bottom surface of the suppressor 1 when the oil pressure decreases, and is then pressed against the rotor shaft 12, thereby stopping the rotation of the rotor shaft 120. The mechanism for stopping the rotation of the rotor shaft 12 is not limited to this, but any mechanism can be used as long as it can stop the rotation of the rotor shaft 120 by pressing the suppressor 1 with spring pressure. Good too. In addition to the above, for example, the convex portion 9 may be tapered on the inside, and this tapered surface may be brought into contact with the fourth terrestrial shirt 2. Reference numeral 10 denotes a proximity switch, which serves to prevent the pressing body 1 from returning too far when hydraulic oil is supplied from the oil port 5. That is, the suppressor IK
If the hydraulic pressure is applied without limit, the disc spring 2 will be damaged, so it acts to stop the suppressor 1 in a fixed position. The end of the rotor shaft 12 is fitted into the central opening of the pressing body 1. Reference numeral 13 denotes a flange and a flange installed opposite to the rotor shaft 12, and a vane (not shown) is fixed between the 7 flanges 13 (the illustrated rotary actuator is a two-vane type). 14 is a stopper for setting the rotation angle of the rotor shaft 120, and is held in a fixed position by a core metal 15 inserted through the cylinder 11. 1
6 is a radial bearing that is driven from both sides of the cylinder 11 to firmly support the rotor shaft 12'f;
A pair of oil ports 7 are provided on both sides of the stopper 14.

To explain the operation of the present invention in an embodiment, the illustrated state is a case where the rotation of the rotor shaft 12 is stopped, and from this state, the oil boat 5y! 1
When a certain amount of hydraulic oil (during normal operation) is supplied through ', the suppressor 1 is pushed back against the disc spring 2 by the hydraulic pressure. Then, the suppression of the holder spring 8 by the convex portion 9 is released, and the rotor shut 12 is released from the suppression by the holder spring 8 and starts normal rocking rotation movement. When the supply of hydraulic oil decreases due to a power outage, malfunction, intentional operation, etc., the suppressor 1 is pushed by the disc spring 2.
