The course of work of the embedded force-reducing device of the recoverable drilling tool in lake is as follows under Antarctic Ice described in the utility model：

The power resources of the force-reducing device provide power by motor 68, pass through deceleration in driving mechanism 6, driving mechanism 6 Driving spindle 61 rotates after device 66 slows down, and main shaft 61 drives five driven gears 44 of follower 4 by driving gear 63 Synchronous rotary, and then drive five roll synchronous rotaries；

Cable enters from the central hole of top plate 2, first through the big guide wheel in the big idler plate of No.1 in big web wheel component 3 Guiding, cable is led from vertical direction for horizontal direction, cable starts the winding of first layer at this time：As shown in figure 8, the line Horizontal direction winding path of the cable in follower 4 is similar to positive five-pointed star technique of painting track, and cable winds first two first Then the first layer ring winding groove of number roll 42 is spaced first No.1 roll 41 and winds second No. two roll 42 first layer ring winding groove, then it is spaced second No.1 roll 41 winds No. two rolls 42 of third first Layer ring winding groove, then it is spaced the first layer ring winding that first No. two roll 42 winds first No.1 roll 41 Groove is finally spaced the first layer ring winding groove of second No. two rolls 42 winding No. two roll 42 of third, until This first layer coiling terminates；

After terminating first layer coiling, cable will be oriented to by the big guide wheel on No. two big web wheel in big web wheel component 3, will Cable is exported from third No. two rolls 42, and is vertically oriented to next layer, then through under on the big web wheel of No.1 One layer big guide wheel is oriented to, and cable is led again from vertical direction for horizontal direction, and cable starts the winding of the second layer at this time；Second Layer coiling is identical as the mode of first layer coiling, is positive five-pointed star formula wiring；After second layer coiling carry out third layer around Line, until after cable completes three layers of coiling, from the third layer export of No. two rolls 42 of third.Five in follower 4 Roll and corresponding five driven gears 44 constitute similar five jiaos of planetary gear mechanisms, can increase line using five rolls The cornerite of cable and roll contact position, after cable is by force-reducing device described in the utility model, internal force greatly reduces, and alleviates whole The burden of a drilling tool effectively decomposes load, increases load-bearing, it is ensured that is safe and reliable.

Since there is the driving of driving gear 63 at the center of driving mechanism 6, so cable cannot be pierced by from centre, it is then sharp again Cable derived from 4 level of follower is led as vertical direction with the small idler plate component 7 being placed on intermediate plate 5.It leads at this time Go out the cable of intermediate plate 5 does not make cable again in the center of device in order to keep the symmetrical balance and stability of mechanical structure The central through hole of bottom plate 8 is exported via the two small idler plate component 7 on bottom plate 8.

Cable after force-reducing device described in the utility model, by orderly wind and with the friction between line groove, Mitigate the internal force close to lower section one end cable, cable is made reliablely and stablely continuously to discharge.

Since cable bears a heavy burden, tight and there are frictional force between roll, so entering the line of device by the above process The power carried on the cable of cable and guiding device differs, therefore realizes and subtract power function；No.1 roll 41 and No. two rolls 42 rotate synchronously, and so that cable is moved by friction with this.

After rubbing subtract power as described above, it can realize that force-reducing mechanism described in the utility model works in subglacial heavy load Under the conditions of steady and continuous operating, and cable can effectively lighten the burden after by the force-reducing device, it can be achieved that heavy load run.
