[specific embodiment]
Below the utility model is described in further detail, the utility model is still more clearly for the people of this professional skill field.
The fire water monitor of this improvement gun tube runner can be fixed by the horizontal rotation seat of horizontal rotation joint bottom according to the environment needs, the direct current generator 4 of horizontal rotation joint 1 and pitching rotary joint 3,11 are connected on the sequence control element of control cabinet, as the PLC controller, encoder or relay etc., control cabinet can be fixed in 12 ones on big gun head, drive direct current generator 4 by control cabinet, 11 rotate, thereby drive the gyration of control horizontal rotation joint 1 and pitching rotary joint 3, and then the rotation of control horizontal rotation portion and pitching rotary part, when control cabinet is malfunctioning, then by handwheel 1-2,3-2 drives horizontal rotation joint 1 and rotates with pitching rotary joint 3, does and horizontally rotates or elevating movement thereby drive in horizontal rotation portion and the pitching rotary part the formed gun tube of each radius of curvature pipe fitting.
