Telescopic belt type conveyer retractable belt device

The utility model relates to a telescopic belt conveyer folding and unfolding apparatus for fully-mechanized mining work plane comprising a hydraulic pressure winding device (6), an entrain device or the like, Wherein the hydraulic pressure winding device (6) comprises a machine base (11), a rotating supporting leg (17), a rotating stand (12), a belt-lift oscillating beam (14), a belt-lift screw block (13), a winding shaft (16), a hydraulic pressure winding motor (15) or the like. The machine base is fixed on the bottom board, on which the rotating supporting leg is fixed, and the rotating stand is equipped on the rotating leg which can rotate. A rotating screw block (18) is hinge connected between the stand and the machine base. Both ends of the rotating stand are hinge connected with an end of the belt-lift oscillating beam of which the other end is equipped with the winding shaft which is actuated by the hydraulic pressure winding motor. The belt-lift screw block is hinge connected between the belt-lift oscillating beam frame and the rotating stand. The winding shaft is provided with a traversing slot for pressing adhesive tape head, a clamping plate and a screw bolt. The clamping device may adopt the fore and rear hydraulic pressure entrains conformation and strap conformation. By utilizing hydraulic pressure machinery to wrap around adhesive tape and, the utility model realizes folding and unfolding adhesive tape, relieves hard physical labor, promotes work efficiency, and can be operated conveniently.
