Embodiment
As shown in Figure 1; electric wire described in the utility model; cable is removed clutch and the overload protection arrangement of receiving mechanism and is comprised: decelerator 1; mechanical clutch 3; supporter 21; disk body 6; handwheel 14; described supporter 21 is by being fixedly welded on an end in the disk body 6; decelerator 1 is connected with mechanical clutch 3 left clutch sheets 20 and is placed in the supporter 21; be provided with spring bearing 2 between left clutch sheet and the supporter; described supporting mass 21 is provided with circumferentially uniform installing hole; steel ball 18; pin 17; spring 16; plug screw 15 successively solid in the supporting mass installing hole; and steel ball 18 is contacted with the right clutch sheet 19 of mechanical clutch; right clutch sheet cylindrical and steel ball corresponding position are provided with V-shaped groove 22; steel ball 18 partly drops in this V-shaped groove 22, the right clutch sheet is connected with handwheel with handwheel bindiny mechanism by clutch.
Described clutch and handwheel bindiny mechanism comprise pull bar 4, bearing 8, adjust bolt 7, hinge plate 10 and screw shell 13, fixing described bearing 8 near the other end in the disk body 6, the fixing respectively screw shell 13 of adjusting bolt 7 and being attached thereto on the end plate of these bearing 8 bottoms and disk body 6 ends, handwheel 14, and pass through screw rod 11 with screw shell 13, handwheel 14 connects, bearing 8 tops and mechanical clutch right clutch sheet 19 cylinder lever connecting rods 4, and by locking nut 5 with pull bar 4 axial restraints, 9 be connected hinge plate 10 by shipping and reselling on another market between the tie rod end on bearing top and the screw shell 13.
After adopting said structure, the decelerator that is connected with motor can be with transmission of power to the left clutch sheet, and when left and right sides clutch disc meshed, clutch drove disk body 6 rotations by the effect of steel ball, spring and plug screw, electric wire (cable) can be wrapped on the disk body; If electric wire (cable) is when suffered axial tension is greater than set point when twining; steel ball will roll on the right clutch sheet; disk body is skidded; can carry out overload protection to electric wire (cable); its principle is that steel ball adopts the V-type groove to contact with right clutch; when the suffered axial tension of electric wire (cable) greater than spring during to the tangential component of steel ball pressure at V-type groove place; steel ball will break away from the V-type groove skids disk body; realize overload protection; the size of this tangential component can be by the decrement to spring; the angle calculation of coefficient of elasticity and V-type groove obtains, and also can directly regulate acquisition by test to spring.
Electric wire (cable) remove receive mechanism usually all requirement can under off-position, carry out manual work, during manual operation, rotate counterclockwise handwheel, make screw rod promote screw shell to left movement, hinge plate drives pull bar and moves right, and left and right sides clutch disc is thrown off, and can throw off decelerator, make mechanism be in off-position, carry out manual electric wire (cable) and remove receipts.Adjustment bolt wherein is used to limit the disengagement stroke of left and right sides clutch disc, prevents that steel ball from deviating from.
