Title: Improved hoist controller
IPC: B66B1/12
Filed: 1960-08-29
Abstract: 892,004. Winding apparatus. LILLY, A. R. Aug. 29, 1960, No. 29773/60. Class 78 (5). A hoist controller for regulating the trips of a mine hoist comprises an epicyclic gear train constantly driven by means coupling it to the hoist drum and a normally stationary cam dial carrying decelerating cams, the dial being automatically coupled to the drum through the said gear train at a predetermined point in each trip so as to bring a decelerating cam into a position in which it operates hoist-decelerating means. As shown, a shaft 12, Figs. 3 and 5, driven by the drum 13 itself drives a shaft 28 to which the sun wheel 16 of the epicyclic gear is secured. The cam dial 20 and an arm 19, on which the planets 18 of the said gear are rotatably mounted (see Fig. 3), are both secured to a shaft 21 in line with shaft 28. Discs 29, 30 freely rotatable about the shaft 21 carry respective stops 31, 32 where angular separation is adjustable by the operation by the hoist driver of a handle connected by linkwork (not shown) to the said plates. On each of the up and down trips one of these stops engages one of the lugs 33, 34 on the cage 17 of the epicyclic gear to stop its rotation and thus turn the shaft 21. This rotation brings the appropriate one of the cams 22 on the dial 20 into engagement with the lever 52 which acts through the linkage 53, 51, 48, 49 (Fig. 4), on a switch 50, on the operation of which the hoist is retarded. The lever 51 has another arm which is connected by a linkage 47 with a centrifugal governor 25 by which the switch 50 is also operated at any stage in the trip in the event of overspeeding. Over-winding is similarly prevented by switch 40 operated by a cam 39 carried by each cam 22, and further cams 37 serve to operate an acceleration switch 38 which in turn operates a device 54 by which the fulcrum of lever 49 is so moved as to prevent the centrifugal governor from operating the switch 50 during the acceleration period at the start of each trip. When the cage of the epicyclic gear train ceases to be held by its stops, the cam dial is returned to its normal inoperative position (Fig. 7), by means of the weight 55.
