Fig. 2 is the locking state scheme drawing of rotating shaft.
Fig. 3 is the releasing orientation scheme drawing of rotating shaft.
Fig. 4 is the utility model state conversion process scheme drawing.
Fig. 5 is the utility model folded state scheme drawing.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the manual fast folding derricking gear of the utility model comprises the base 1, first bracing frame 16 and second bracing frame 15 that are installed on the fixed platform; The top of this base 1 is equipped with rotating shaft 2; Be evenly distributed with position-limited trough 20 on the rotating shaft 2 bottom circumference; Installation foot pedal 17 on base 1, the stage casing of stretcher 17 and base 1 upper articulation, the bottom of stretcher 17 is connected base 1 bottom through stage clip 18, and stretcher 17 tops connect latch 19 through bearing pin, the end contact position-limited trough 20 of latch 19; When operating personal foot-treadle 17, stretcher 17 rotates drive latch 19 and outwards moves, and throws off with position-limited trough 20, and rotating shaft 2 is unclamped rotating shaft 2 this moment and can on base 1, be rotated; The pin of operating personal unclamps stretcher 17, and stage clip 18 outwards promotes stretcher 17, and stretcher 17 rotates drive latch 19 and moves inward, and latch 19 inserts position-limited troughs 20, and rotating shaft 2 lockings can not be rotated;
Be equipped with pin hole on rotating shaft 2 tops and first bracing frame 16; Column 4 is installed in base 1 top through rotating shaft 2, and column 4 bottoms and rotating shaft 2 middle parts are hinged, and captives joint with rotating shaft 2 tops through first latch 3 in the pin jointed end of column 4 top; Base 1, first bracing frame 16 and second bracing frame 15 are installed on same the straight line.
Hand winch 7 is fixed on the column 4, have on the hand winch 7 crank 5 handles 6 and; First pulley 8 is fixed on the top of column 4; One end and the column 4 of crossbeam 10 are hinged; Crossbeam 10 other ends are equipped with second pulley 11; Steel rope 9 in the hand winch 7 hangs on second pulley, 11 belows behind the groove through first pulley 8, second pulley 11 successively, and hook 12 is connected the end of steel rope 9; Crossbeam 10 stage casings are provided with pin hole, and an end and the column 4 of fork 14 are hinged, and this end that the other end of fork 14 is provided with pin hole and fork 14 connects crossbeam 10 through second latch 13;
