Twin drum winch of the present utility model, a total drg is set, and by being installed in the helicoidal gear on the reel, control be installed on the reel gear be installed in gear on the reducer output shaft and mesh or break away from, thereby can realize two work switchings between the reel, both simple in structure, easy to operate again, also cost-saved.
Description of drawings
Fig. 1 is the front view of the utility model twin drum winch embodiment.
The specific embodiment
With reference to figure 1, the embodiment of the utility model twin drum winch comprises electrical motor 1, retarder 3, two reels 9 that link to each other with retarder 3 by driving device, 6, between electrical motor 1 and retarder 3, also be provided with coupler 2 and drg 10, one gear 11 is installed on the output shaft 4 of retarder 3, two reels 9, coaxial gear 5 and gear 12 are installed respectively on 6, gear 11 is meshed with gear 5 and gear 12 respectively, wherein the center shaft 13 of at least one reel 9 matches with gear 5 by spline 14, described center shaft 13 axial restraints, reel 9 axially is connected with gear 5, center shaft 13 is provided with outside thread, on the center shaft 13 helicoidal gear is installed, and helicoidal gear comprises rocking arm 17 and the nut 7 that links to each other with rocking arm 17, nut 7 matches with outside thread on the center shaft 13, and with end plate 18 axial restraints of reel 9.Also be provided with brake gear in reel 9 end plates 18 outsides, this brake gear is the friction disc brake, comprises spring bar 15 that is installed on the spring perch 16 and the friction disc 8 that is installed on this spring bar 15.Have the blind hole perpendicular to center shaft 13 in rocking arm 17 outsides, a perpendicular short slab is installed in end plate 18 outsides, and lock screw 19 is installed on it, and lock screw 19 can pass the tapped through hole on the short slab and insert in the blind hole in rocking arm 17 outsides.
Connect the power supply of electrical motor 1, generally, a reel job in the twin drum winch.The working condition of two reels in needs switching twin drum winch, make electrical motor 1 outage earlier, drg 10 is held braking automatically tightly, can make the complete stall of twin drum winch immediately, this moment the rocking arm 17 on the rotating drum 9, the nut 7 of helicoidal gear on the reel 9 is rotated with respect to center shaft 13, because center shaft 13 axial restraints, so reel 9 moves axially along center shaft 13 together with gear 5, when two gears are about to break away from, the end plate 18 of reel 9 contacts with friction disc 8 on the friction disc brake that is positioned at its outside, is rotated further rocking arm 17 until gear 5 and gear 11 jump out of meshs, and reel 9 is along the circumferential direction locked.Lock screw 19 is screwed in the blind hole in rocking arm 17 outsides, can be with rocking arm 17 latched positions.
