The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design, be easy to install.
2, the utility model gathers the Continuity signal of magnet and magnetic induction sensor by controller; thereby further judge whether the slack rope phenomenon to occur, as the slack rope phenomenon occurs, cut off putting the power supply of rope motor by relay; make and put the rope motor stopping; stop putting rope, after the fault of slack rope is got rid of, then cutin relay; recovery is to putting the power supply of rope motor; and then continue to make skip bucket to transfer, and guaranteed the safety in the skip bucket decentralization process, avoid causing disconnected rope because of slack rope.
3, a plurality of described magnetic induction sensors of the utility model are evenly laid along the derrick bearing of trend.Can make like this controller collect the Continuity signal of magnetic induction sensor and magnet more stable, thereby improve stability and the validity of this mining skip bucket rope-loosing protection device operation.
4, of the present utility modelly realize that cost is low, result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, and novel in design rationally functional reliability is high, long service life, and actv. has guaranteed that the safety of skip bucket transfers, result of use is good, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of mining skip bucket rope-loosing protection device as depicted in figs. 1 and 2, comprise controller 10, coder 9, relay 11, magnet 5 and with the suitable a plurality of magnetic induction sensors 6 of magnet 5, described magnet 5 is arranged on a lateral surface of skip bucket 7, a plurality of described magnetic induction sensors 6 all are arranged on derrick 4 and on a medial surface corresponding with described magnet 5, a plurality of described magnetic induction sensors 6 are laid along the bearing of trend of derrick 4, and described coder 9 is coaxially installed with the rope motor 8 of putting of putting rope drum 1 rotation for drive; Described coder 9 and a plurality of described magnetic induction sensor 6 all join with the input end of controller 10, and the mouth of described controller 10 and relay 11 join, described relay 11 with put rope motor 8 and motor power supply 12 and join.
In the present embodiment, put 8 drives of rope motor and put rope drum 1 rotation, be wrapped in the steel rope put on rope drum 1 after head sheave 2 guiding, gradually skip bucket 7 is constantly transferred along bend 3, magnet 5 on skip bucket 7 makes magnetic induction sensor 6 conductings on derrick 4 successively, the signal of 10 pairs of magnetic induction sensors 6 of controller and coder 9 outputs is gathered, once skip bucket 7 can not be along bend 3 normal descends, when steel rope there will be relaxed state, the signal of 10 pairs of magnetic induction sensors 6 of controller and coder 9 outputs is gathered, and judge whether skip bucket 7 drops are less than the length that steel rope is transferred, when the difference of the two is greater than safe length, think and the slack rope phenomenon occurs, thereby controller 10 disconnects by closed relay 11 current supply circuit of putting rope motor 8, make and put 8 shutdown of rope motor, stop putting rope, after the fault of slack rope is got rid of, cutin relay 11 again, recovery is to putting 8 power supplies of rope motor, and then continue to make skip bucket 7 to transfer, realized rope creep protection.The advantage of this is mining skip bucket rope-loosing protection device be highly sensitive, safety performance is reliable.
As shown in Figure 1, described magnet 5 is arranged on the bottom of skip bucket 7 one lateral surfaces.A plurality of described magnetic induction sensors 6 are evenly laid along derrick 4 bearing of trends.Can make like this controller 10 collect magnetic induction sensor 6 more stable with the Continuity signal of magnet 5, thereby improve stability and the validity of this mining skip bucket rope-loosing protection device operation.In the present embodiment, described controller 10 is the PLC controller.Described magnet 5 is permanent magnet.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belong in the protection domain of technical solutions of the utility model.
