Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, motor gear; 2, shifting slide gear; 3, slippage bar; 4, worm screw; 5, back-moving spring; 6, worm gear; 7, locking nut; 8, push rod; 9, manual axle; 10, Tong Gai; 11, handwheel; 12, spring; 13, ball; 14, spacer; 15, bearing; 16, bearing; 17, motor; 18, jackscrew; 19, clutch tooth embedding; 20, clutch tooth embedding; 21, clutch tooth embedding; 22, clutch tooth embedding.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, in the gear-box of fire monitor bottom, worm gear 6 is installed, the worm screw 4 that has clutch tooth embedding 21 with the front end of worm gear engagement is installed in gear-box by locking nut 7 and bearing 15,16, be movably installed with the shifting slide gear 2 that end face has coupling clutch tooth embedding 22 at the worm screw front end, the motor gear 1 and the motor 17 thereof that are meshed with shifting slide gear are installed in gear-box.The arrangement of clutch that drives shifting slide gear and worm screw is to be shaped on ladder hole at the worm screw center, slippage bar 3 and back-moving spring 5 thereof that front end is connected with shifting slide gear are installed in the ladder hole, by spacer 14 the logical lid 10 that has centre bore is installed on worm screw rear end bearing 15, the logical lid installed the manual axle 9 that has handwheel 11 in the centre bore, manually axle front end center is axially installed with and drives the push rod 8 that the slippage bar moves, manually the front end face of axle is shaped on clutch tooth embedding 19, manually be shaped on the cannelure that the cross section is semicircle on the face of cylinder of axle, logical ball 13 and spring 12 and the jackscrew 18 that is equipped with on the sidewall with the cannelure coupling that cover, corresponding being shaped on and the manually clutch tooth embedding 20 of axle clutch on the described worm screw rear end face.Like this, because the manual of fire monitor transposition is arranged in the hollow worm screw with electronic switching device shifter, make the reduction case of this device and other modular construction simplify.Manual and electronic switching device shifter realizes making the operating physical force of manual switchover power and handwheel on worm screw less, is convenient to the manual operation that operating personnel carry out the fire monitor transposition.Manually be arranged in the hollow worm screw and make structure more simple and reliable with the correlated parts of electronic switching device shifter, the part that relates to also seldom, thereby manufacturing cost is lower.This device motoring condition and manual state be converted to mechanical pattern, therefore have very good handling safety performance.The utility model also has little, the lightweight advantage of volume in addition.
Operation principle:
During this device of electric control operation, the power of motor 17 is delivered to shifting slide gear 2 by motor gear 1, because shifting slide gear is fixing with slippage bar 3, so mesh in 22 maintenances of the clutch tooth embedding on the shifting slide gear under the effect of back-moving spring 5 and the clutch tooth embedding 21 on the worm screw 4, and then the worm gear 6 that makes motion be delivered to worm screw and be engaged with, the worm-gear driven fire monitor rotates.
The other end of worm shaft is equipped with bearing 15, and with itself and bearing fixing, pack into behind the gear-box, can be by the axial location of spacer 14 and the whole worm component of Tong Gai 10 constraints by worm component by the screw thread on the worm screw for locking nut 7.
During manual operation, axis direction along handwheel 11 promotes handwheel, can act on the slippage bar with manual axle 9 push rods that are connected 8, slippage bar drive shifting slide gear is along axial-movement and make its clutch tooth embedding 22 and worm shaft clutch tooth embedding 21 break away from engagement, when handwheel is shifted the precalculated position onto, manually embedding 19 of axle clutch tooth and worm screw other end clutch tooth embedding 20 engagements, but this device of manual operation this moment.When manually axle was positioned at manual position, ball 13 was at the endless groove that can fall under the effect of spring 12 on the manual axle, but the fixed manual operating position.
Handwheel outwards should be extracted after the electric device manual operation, be made it get back to motoring condition.Occur electronic maloperation during manual operation and can only make shifting slide gear and the rotation of slippage bar, can not drive the handwheel rotation, thereby can guarantee operator's safety.
