The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described:
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 5.
A kind of manual hoist comprises frame 1, manual driving device, driving device, reel 2, and an end face of frame 1 is provided with detouchable cover plate 3, and cover plate 3 is provided with bearing 4;
The hand wheel shaft 5 that driving device comprises, be set in miniature gears 6, the drum shaft 7 that is connected with reel 2 on the hand wheel shaft 5, be set in the big gear wheel 8 on the drum shaft 7, miniature gears 6 and 8 casees engagements of big gear wheel; Hand wheel shaft 5 is installed on the frame 1 and by cover plate 3 and reaches outside the frame 1; Manual driving device comprises the Handleset 9 of an end that stretches out frame 1 that is installed in hand wheel shaft 5, and manual driving device drives reel 2 rotations by driving device;
Driving device is provided with brake equipment, brake equipment comprises the handwheel sleeve 10 that is set on the hand wheel shaft 5, be set in drg seat 11 on the hand wheel shaft 5, be installed in ratchet 12 on the drg seat 11, be installed in the ratchet 13 that a pair of and ratchet 12 on the cover plate 3 matches, handwheel sleeve 10 is installed in the bearing 4,11 of handwheel sleeves 10, drg are connected by multiple screw thread with hand wheel shaft 5 respectively, between handwheel sleeve 10 and the ratchet 12, be respectively arranged with friction lining 14 between drg seat 11 and the ratchet 12.
An end that stretches out frame 1 of hand wheel shaft 5 is provided with end cover 15, and end cover 15 outsides are equipped with fluted nut 16, is provided with packing ring 17 between fluted nut 16 and the end cover 15, and fluted nut 16 is provided with spring cotter 18.
