The invention provides a worm rod double-revolving electric control fire water monitor. A traditional fire water monitor is single in adjusting mode and not easy to control the revolving precision. The worm rod double-revolving electric control fire water monitor comprises a base, a lower bent pipe, an upper bent pipe, a gun head, a horizontal revolving mechanism and a pitching revolving mechanism; and a water inlet end of the lower bent pipe is rotationally arranged on the base. The horizontal revolving mechanism comprises a first motor and a first worm rod; and the first worm rod is engagedwith a water inlet end of the lower bent pipe. The pitching revolving mechanism comprises a second motor, a second worm rod and an upper pivot shaft; and the second worm rod and the upper pivot shaftare partially engaged. The second worm rod in the pitching revolving mechanism is rotated; and the part thereof engaged with the upper pivot shaft drives the upper pivot shaft to rotate. In water injecting operation, the second worm rod in the pitching revolving mechanism is rotated, and the part thereof engaged with the upper pivot shaft drives the upper pivot shaft to rotate, so that the revolving of the gun head is controlled more precisely in the vertical direction.
Description
technical field [0001] The invention relates to fire-fighting equipment, in particular to an electrically controlled fire-fighting monitor, which belongs to the technical field of fire-fighting equipment. Background technique [0002] Traditional servo motor-controlled fire monitors are equipped with horizontal and pitch slewing mechanisms, both of which are electronically controlled worm gears and worms. The range of rotation angles on the horizontal plane and perpendicular to the horizontal plane is usually slightly less than 360°, which has the characteristics of large rotation angles. In the prior art, fire water monitors usually only have an electronic control mode, and the adjustment mode is single, and the second worm and the upper pivot of the pitch and slewing mechanism are generally independent of each other, so it is difficult to control the rotation accuracy. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention p...
