Two pedestals, one is fixing pedestal (31), one is movable pedestal (31 '), respectively be cross, respectively there is the round pin (311) of protrusion this spider upper end, the protruding pin external diameter of two pedestals equate and protruding pin protruding in relatively, the pull rope wheel shaft (38) of the spacing of this protruding pin outside dimension and two pedestals and standard component is corresponding;

One spool (32), be hollow tubular, one end of this spool fixedly connected fixing pedestal (31), the end in addition of this spool is to be installed with movable pedestal (31 ') movingly, this activity pedestal is promoted and locking by spool latch handle (33), this latch handle is made of locknut (331) and the handle (332) that is fixed on the locknut, and this locknut cooperates with the trapezoidal thread of spool (32) end cylindrical;

At the inner chamber two ends of spool (32) rolling bearing (321) is housed, and locatees with door (322), this bearing is supported on the fixed axis (34), and this fixed axis is supported on spool support arm (35) front end of hauling machine and compresses with end cap;

C. spool support arm (35) rear end is articulated in the upper end of the bearing support (351) on the hauling machine chassis (11), the hinged support cylinder in the middle part of this support arm (351) (352), this support cylinder (352) is held the triangular supports structure that is articulated in the lower end of bearing support (351) and constitutes adjustable lifting in addition, this bearing support (351) upper end also is provided with elevator take-up mechanism locking device (353), this locking device (353) can use similar pin-and-hole, the structure of latch;

Be set with spool driving lever (36) in the end of described fixed axis (34), driving lever (36) is equipped with spool shifting block (361), fixed axis (34) end is connected with an axle sleeve (363) by connecting screw rod (362), the front end sleeve of this connecting screw rod (362) is equipped with compression spring (3621), there is turning handle (3622) the screw rod end, on the cross section of the junction of axle sleeve (363) and fixed axis (34) gap (364) is arranged, the outer shroud suit that is enclosed within the bearing (365) on axle sleeve (363) axle journal a drive (366), this drive (366) is the freewheel clutch structure, and the disjunctor braked wheel (367) of this drive is by brake band (368) plugging.
