Embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; The said boom sprayer spray boom up-down self-locking device according to the present invention is made up of travelling gear (pinion 3, gear wheel 5), ratchet self-locking device (single direction ratchet 11, ratchet 10, rotating shaft 15, self-locking handle 2, top cover 16, axle sleeve 2 17, backing plate 1, backing plate 2 19, rectangular thread end 20), steel wire rope combination (baffle plate 1, baffle plate 2 13, steel wire rope 14, hollow rotating shaft 22), shell combination (shell 1, dead axle 6, rotating shaft 15), elevating mechanism (fixed pulley 23, roller 24, riser 27, stand combination 29, bracing frame combination 31).
Dead axle 6 is packed in the shell 1, and the hollow rotating shaft 22 of lay winding wire ropes 14 overlaps on it, and baffle plate 1 and baffle plate 2 13 are fixed on the two ends of hollow rotating shaft 22 respectively, and gear wheel 5 connects firmly with hollow rotating shaft 22; Rotating shaft 15 is installed on the shell 1; Be with axle sleeve free to rotate 1 with shell 1 contact position one end; The other end is with top cover 16 free to rotate, and pinion 3 is packed in the rotating shaft 15 and meshes with gear wheel 5, and the end of rotating shaft 15 is rectangular thread ends 20; With self-locking handle 2 through being threaded, freedom suit axle sleeve 2 17, backing plate 1, ratchet 11, backing plate 2 19 successively between top cover 16 and self-locking handle 2.
Ratchet 10 1 ends are rotatably installed on the shell 1 through bearing pin 4, the other end through spring 9 with connect spring plank 8 and be connected, company's spring plank 8 is connected on the shell 1, ratchet 10 matches with ratchet 11.
Crossbeam 26 firmly is connected with two columns 30, and stand combination 29 is connected on the crossbeam 26, and riser 27 is connected in the stand combination 29, and shell 1 firmly is installed on the riser 27 through screw 21 and nut 28.
