Described sheave drive mechanism comprises the first driver plate 28, first straight pin 7, second driver plate 24, second straight pin 29, sheave 5, Compress Spring 26, spline 25 and splined hub 27.First driver plate 28, second driver plate 24 is fixedly connected with the first rotating shaft 6, second rotating shaft 8 respectively and the first straight pin 7 on the first driver plate 28 and the second straight pin 29 on the second driver plate 24 have 180 ° of phase differences, spline 25 coordinates with splined hub 27, spline 25 is welded on sheave 5, and Compress Spring 26 is enclosed within spline 25;
The push-and-pull handrail 17 of described auxiliary body is welded in frame 2, rotary column 9 and splined hub 27 periphery interference fit, the inner headed face of rotary column 9 and height regulating rod 11 matched in clearance, turning handle 10 is welded on rotary column 9, lock-screw 16 coordinates with the screwed hole on rotary column 9, bracing frame 12 is welded on height regulating rod 11, and bayonet socket rotating shaft 14 is welded with hydraulic giant bayonet socket 15 and coordinated with bracing frame 12 and forms revolute pair, the threaded engagement of lock-nut 13 and bayonet socket rotating shaft 14 end.
Described first straight pin 7 and the second straight pin 29 have 180 ° of phase differences.
The increment face of described spline 25 and splined hub 27 is inclined-plane, and spline 25 upper end is the optical axis with guide effect.
Described frame 2 tail end has wedge 30.
Operation principle and process:
Fire-fighting lance is stuck on hydraulic giant bayonet socket 15, the azimuth of sheave 5 is regulated to make it just coordinate with the first straight pin 7 on the first driver plate 28 or the second straight pin 29 on the second driver plate 24, pull button 23, cam 22 jack-up tappet 4 is made to promote sheave 5 to move to and the first straight pin 7, second straight pin 29 sustained height, meanwhile, be fixed in the spline 25 on sheave 5 to be engaged with splined hub 27 by the ramp effect in increment face.Starter motor 21, the first driver plate 28 and the second driver plate 24 is driven to reversely rotate by gear drive, and there are 180 ° of phase differences due to the first straight pin 7, second straight pin 29, therefore the reciprocally swinging that horizontal direction 0-90 ° of scope made by sheave 5 can be stirred, thus the rotary column 9 connected with splined hub 27 is made to do same swing.The inner headed face matched in clearance of height regulating rod 11 and rotary column 9, after regulating height, available lock-screw 16 is locked, and hydraulic giant bayonet socket 15 can rotate around bayonet socket rotating shaft 14, and by lock-nut 13 locking.Thus make fire-fighting lance do the motion of double freedom, realize semi-automation operation, saves manpower.
After pulling button 23, sheave 5 departs from the straight pin on the first driver plate 28 or the second driver plate 24 under Compress Spring 26 acts on, and now can use the pure manual operation of turning handle 10, convenient, flexible.
The wedge 30 of frame 2 tail end can increase resistance, offsets most of reaction of water gun.
