Abstract
The utility model relates to a constant tension cable winding drum which is arranged at the right end of a hollow shaft of a current collector. An output shaft and the hollow shaft of a reducing mechanism are parallelly arranged in a worm gear box body and a current collector box body. Left ends of the output shaft and the hollow shaft are respectively provided with a gear, and an intermediate gear is meshed between the two gears. A worm gear which is movably matched with a shaft sleeve of the output shaft is meshed with a worm rod which is arranged on the worm gear box body. A sliding ring of the current collector is arranged on the hollow shaft, a foreign cable is connected to a wiring terminal of the sliding ring, and an input power cord of a mobile device body is connected to a wiring terminal of a carbon brush. The utility model solves the problem that at present cables of various electrical devices, which walk on a rectilinear orbit are capable of winding and unwinding.
Description
The utility model belongs to the built on stilts installation of cable or electric wire to be regulated and the constant device technique field of maintenance mechanical tension.
The present cable of the electrical equipment of walking in orbit, what have pulls in ground, and being suspended on of having is aerial, is damaged by other object easily or pounds disconnectedly, or because of dragging the wiping surface wear repeatedly, very dangerous, lack service life.Existing spring cable reel, the torque motor cable drum, fluid power manifold type cable drum has solved this problem, but these cable drums all can not solve ideally equipment operation and twisted and released of the cable synchronously, the key issue such as suitable of cable stretch.
The purpose of this utility model will provide a kind of equipment operation and twisted and released of the cable of making synchronous exactly, and cable stretch is constant, can satisfy the requirement of different mobile electrical equipment running velocitys, the constant-tension cable reel that range of use is wide.
The utility model is such design-calculated: a kind of constant-tension cable reel is by the worm and wormwheel speed reduction gearing of permanent tension force output, current colector mechanism and reel are formed, be characterized in: reel 21 is installed in hollow shaft 13 right-hand members of current colector, the output shaft 8 of speed reduction gearing and hollow shaft 13 are installed in parallel in the worm gear case 10 and in the current colector casing 14, the left end of output shaft 8 and hollow shaft 13 is equipped with gear 9 respectively, 12, be engaged with intermediate gear 11 between this two gear, setting nut 1 is housed on the output shaft 8, worm gear 6 and worm screw 5 engagements that are installed on the worm gear case 10 with the axle sleeve running-fit of output shaft 8, the left end of worm gear 6 has left grinding disk 7 spacing, and right-hand member is compressed by spring 3, right grinding disk 4 location; The slip ring 19 of current colector is installed on the hollow shaft 13, and corresponding carbon brush 17 is placed in the brush box of brush holder 18, and brush holder 18 is fixed on the brush holder support 15, and brush holder support 15 is fastened on current colector casing 14 inwalls by screw; External cable 20 is connected on the binding post of slip ring 19 by reel 21, hollow shaft 13, and the input power cord of mobile device body connects on the binding post of carbon brush 17.
The utility model is to utilize friction lining to produce constant-tension, makes cable in the folding and unfolding process, remains suitable tensioning state, does not need additional other device, makes the electrical equipment speed of travel and cable receive or put synchronously.Output shaft adopts gear structure to connect with hollow shaft, can carry out speed change, adapts to the different electrical equipment speeds of travel, enlarges range of use, gives full play to the in-use performance of cable drum, improves social benefit and economic benefit.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an inner structure scheme drawing of the present utility model.

Transmission of motion is such, when the mobile device setting in motion, when needing the rolling cable, electric motor starting drives worm and wormwheel, under the effect of spring force, worm gear 6, left and right friction disc together rotate, drive output shaft 8 by long key, drive current colector hollow shaft 13 through gear 9,11,12 again and drive reel 21 rotations, rolling cable.
When discharging cable, motor is not worked, and by the pulling force pulling cable expansion of mobile device walking itself, reel 21 counter-rotatings drive output shaft 8 counter-rotatings by hollow shaft 13, gear 12,11,9.Because motor is not worked, under the worm and wormwheel self-locking action, the end face of left and right friction disc 7,4 and the end face of worm gear 6 skid, and under the effect of friction force, the cable of release has constant tension force.
In the course of the work, find that cable is too loose, can screw setting nut 1, compression spring 3 and increase friction force, output torque increases, the cable tensioning.If the tension that cable stretches tight then unscrews setting nut 1, spring relaxation, friction force reduces, and output torque reduces, and the tensile force of cable is also just little, makes cable be in suitable mode of operation, and accident can not meet accident.
