Operation principle of the present utility model:
Entry is come in and gone out and moved towards: the central via hole in entrance worm-wheel shaft lower end is the fire water water inlet, and fire water is through barrel central authorities' via hole and outlet worm-wheel shaft, by the water side ejection of big gun head.
Horizontal rotation: the horizontal servo revolution is to be rotated along electrical axis through the horizontal worm screw of horizontal coupling band drive by the horizontal servo motor output shaft; Horizontal worm screw and the engagement of horizontal worm gear, the entrance worm-wheel shaft adopts spline fitted to be connected with horizontal worm gear, because entrance worm-wheel shaft lower surface being fixed by preposition union piece, make and himself do not rotate, the limit levels worm gear can not rotate, thereby makes horizontal worm screw do the circumference rotation around horizontal worm gear center along horizontal worm gear circumference, thereby makes horizontal worm screw should do rotation, around horizontal worm gear circular-rotation, namely horizontal worm movement track is planetary motion again.Because horizontal worm screw, horizontal coupling band and horizontal servo motor link together by horizontal servo motor end face and lower drive case, therefore, horizontal worm screw is when doing to do the circumference rotation along horizontal worm gear center, and lower drive case revolves round the sun around horizontal worm gear circumference together with horizontal worm screw; Lower drive case and barrel are to be fastenedly connected by lower terminal pad, thereby realized that barrel and barrel upper parts all do the rotation of horizontal direction along horizontal worm gear center, have realized the circular-rotation of this SERVO CONTROL fire monitor water side along continuous straight runs.Wherein, the Level tune handwheel is used for manual operation, realizes manually carrying out horizontal rotation, adopts SERVO CONTROL revolution and Manual rotary dual mode, in case with reply servo control fails, the manual revolution of employing remedial measure, meet general fire protection rule requirement.
Vertical revolution: vertical servo turning is to drive vertical worm screw by vertical servomotor output shaft through vertical coupling band to rotate along electrical axis; Vertical worm screw meshes with vertical worm gear, the outlet worm-wheel shaft adopts spline fitted to be connected with vertical worm gear, because the outlet worm-wheel shaft is not fixed by other parts, the revolution of himself is not limited, thereby when vertical worm screw revolution, vertical worm screw meshes with vertical worm gear, and vertical worm gear is rotated, vertical worm gear is connected with the outlet worm-wheel shaft by spline, rotates thereby drive the outlet worm-wheel shaft and synchronize with the big gun head that it is fixedly connected with.Because vertical worm screw only does rotation, when vertical servomotor rotated, upper drive case and barrel did not rotate, and only had big gun head and outlet worm-wheel shaft to do the rotation of vertical plane, had realized this SERVO CONTROL fire monitor water side circular-rotation vertically.Wherein, the vertical adjusting handwheel is used for manual operation, realizes manually vertically turning round, and adopts SERVO CONTROL revolution and Manual rotary dual mode, in case with reply servo control fails, the manual revolution of employing remedial measure, meet general fire protection rule requirement.
Revolution limit position-limit mechanism: spacing when spacing when the lower limit ring is used for lower drive case and reaches turning anticlockwise clockwise together with the barrel horizontal direction, upper limit ring are used for big gun head vertical direction and reach turning anticlockwise clockwise.
The position-limit mechanism of horizontal rotation: the entrance worm-wheel shaft is equipped with the lower limit ring by spline fitted, has less than 360 ° on lower limit ring periphery and supplies the gathering sill of steel ball slip; Be furnished with positive stop on lower drive case, along the circumferential direction have the kidney-shaped deep gouge on the positive stop inner arc surface, steel ball is placed in this groove.Instantly drive case is clockwise or during turning anticlockwise, steel ball rotates along the circumference arc rooved face of lower limit ring, when forwarding the extreme position of gathering sill of lower limit ring to, steel ball will continue revolution along the interior circular arc kidney-shaped deep gouge of limited block this moment, until forward the other end extreme position of limited block kidney-shaped deep gouge to, thereby realized that the spacing and corner of horizontal rotation is greater than 360 °.
Vertical rotating position-limit mechanism: on upper drive case, a stop screw is housed, the upper limit ring along the circumferential direction has one section gathering sill with the stop screw corresponding matching, vertical direction is clockwise or during turning anticlockwise, vertical worm screw drives the rotation of outlet worm-wheel shaft by the spline of vertical worm gear, the outlet worm-wheel shaft drives the upper limit loopback by spline fitted again and turns, until stop revolution when encountering stop screw, thereby realized that vertical slewing limit and corner are greater than 120 °.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
