1. a functional belt conveyor tensioning device, it is characterized in that one can be applicable on large belt conveyor, load-transfer device is had to the integrated apparatus of tensioning, tuningout and slip-skid prevention several functions, package unit is made up of traction system, travelling car (12), belt tensioning drum (11), bend pulley (13), head roll (14) and control system, slip-skid prevention system;

  • Belt tensioning drum described in it (11) is arranged on travelling car (12), and by two covers traction system tethered sliding dolly (12), belt tensioning drum (11) and travelling car (12) are movable along slideway together, realizes tensioning or loosens the object of load-transfer device (18);

    Left motor (1) and right motor (2) rotate forward traction belt tensioning drum (11) simultaneously and travelling car (12) moves forward along slideway together, Conveyer Belt (18), left motor (1) and right motor (2) reverse simultaneously can loosen load-transfer device (18);

    For realizing the target of tensioning and tuningout, traction system overlaps traction system by identical and separate left traction system and right traction system two and forms, and wherein left traction system is made up of left motor (1), left reductor (3), left Steel rope drive cylinder (5) and left haulage cable (7);

    The left side of left traction system tethered sliding dolly (12);

    Right traction system is made up of right motor (2), right reductor (4), right Steel rope drive cylinder (6) and right haulage cable (8), the right side of right traction system tethered sliding dolly (12);

    Control system described in it is made up of Zola'"'"'s force snesor (9), right pulling force sensor (10), left leather belt deviation switch (15), right leather belt deviation switch (16), computing machine (19), Programmable Logic Controller (20) and relay;

    Slip-skid prevention system described in it is made up of pick up camera (17), computing machine (19), Programmable Logic Controller (20) and relay;

    In order to the solid material moisture eliminating belt conveyer conveying is large, easily damage the measuring element of slip-skid prevention system, adopt camera metering system;

    Slip-skid prevention system software described in it utilizes the second function of antitheft image processing software, does not send signal when namely monitoring image is in dynamical state, sends signal to load-transfer device further tensioning when monitoring image remains static.
