Detailed description of the invention
below in conjunction with Figure of description, the invention will be further described:
as Fig. 1, shown in Fig. 2, a kind of winch, it comprises housing 2, motor 3, the worm screw 6 of rotation is driven by motor 3, be meshed with worm screw 6 and the worm gear 8 that can arrange rotationally around Pivot Point Center line, be set in the rope 1 on worm gear 8, winch also comprises the transmission shaft 7 that is fixedly installed with the arbor of motor 3 and for rising to vertex at winch or controlling the inhibiting device that motor 3 shuts down after reducing as far as possible, the axial line of transmission shaft 7 is vertical with the axial line of worm gear 8, worm screw 6 is sheathed on transmission shaft 7 and along the axis of transmission shaft 7 and can arranges slidably, connected by key between worm screw 6 and transmission shaft 7, transmission shaft 7 is arranged with spring 4 and is located at the side of worm screw 6 near motor 3, inhibiting device comprise can be driven by worm screw 6 and on housing 2 slide slide block 5, be arranged at the limit switch 9 that housing 2 can control motor 3 opening and closing, slide block 5 to be set on transmission shaft 7 and to be arranged between worm screw 6 and spring 4, housing 2 is provided with and matches with slide block 5 and can allow the chute 10 that slide block 5 slides, slide block 5 has two control positioies, when being in the first control position and slide block 5 when the left end of chute 10, winch is normally elevated, slide block 5 and limit switch 9 are separated, motor 3 normal operation, when being in the second control position and slide block 5 when the right-hand member of chute 10, winch rises to vertex or reduces as far as possible, and slide block 5 contacts with limit switch 9, and motor 3 shuts down.
