Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Fig. 3:
A kind of Electric Chain Blocks, comprise gear case 1 and motor 2, be provided with in described gear case 1 by the sprocket wheel 3 of bearings, the relevant position of gear case 1 is provided with out chain hole 4, sprocket wheel 3 is provided with chain 5, and the end of chain 5 is connected with suspension hook 6, chain 5 is from going out chain hole 4 to pass, the rotating shaft 7 of motor 2 is connected with the output shaft 8 through centre of sprocket hole, and the outer end of sprocket wheel 3 is set with output gear 9, and output shaft 8 and output gear 9 are by clutch transmission transmission.
Clutch transmission transmission is: comprise the gear wheel shaft 10 be arranged in gear case 1, gear wheel shaft 10 is provided with two braking vanes 11, between two braking vanes 11, clutch is connected with and is connected with a joggle and the intermediate gear 12 be not connected with gear wheel shaft 10 with output shaft 8, and rear end and the output gear 9 of gear wheel shaft are connected with a joggle.
The outside of two above-mentioned braking vanes 11 is equipped with and is pressed in disk spring plate 13 on braking vane 11, the outer end of gear wheel shaft 10 is bolted with setting nut 14, by setting nut 14 precession or back-out being increased or are reduced the application force of disk spring plate 13 pairs of braking vanes 11, and then increase or reduce the friction force between braking vane 11 and intermediate gear 12, change the rated weight capacity of equipment.
The outside of two braking vanes 11 is equipped with the disk spring plate 13 be pressed on braking vane 11, the outer end of gear wheel shaft 10 is bolted with setting nut 14, setting nut 14 connects disk spring plate 13 by bearing, the pressure that precession or back-out setting nut 14 increase disk spring plate 13 pairs of braking vanes 11 makes braking vane 11 clamp intermediate gear 12; Or the pressure reducing disk spring plate 13 pairs of braking vanes 11 makes the gripping power of braking vane 11 pairs of intermediate gears 12 reduce
Above-mentioned motor 2 is connected with controller 15, and controller 15 controls motor 2 and rotates, and the button pressed on controller 15 can control weight lifting.
The top of above-mentioned gear case 1 is provided with hook 16, and hook 16 is used for equipment to be fixed in frame.
Be provided with recoil spring 17 between above-mentioned suspension hook 6 and chain 5, prevent the weight when hoisting heavy from occurring to touch with equipment under effect of inertia and clash into.
