Description
Technical Field
The invention relates to the technical field of electric power, in particular to a real-time forced belt deviation correcting device.
Background
At present, the deviation rectifying devices used by a belt conveyor system in an electric power system and other industries are all mechanical deviation rectifying devices, namely, the deviation rectifying devices on one side protruding out generate thrust by means of belt deviation, so that a rotating mechanism of the deviation rectifying devices rotates by an angle, and the purpose of correcting the belt deviation is achieved. The currently known deviation rectifying devices comprise: the automatic aligning device comprises a groove type aligning idler set, a conical lower aligning idler set, a conical upper aligning idler set, a flat lower aligning idler set, a bidirectional reversible automatic aligning idler set, a friction lower aligning idler set, a friction upper aligning idler set, a baffle roller connecting rod type automatic aligning idler set, a baffle roller type automatic aligning idler set, a side baffle roller type automatic aligning idler set, a DT II type friction aligning idler set, an axis swinging type automatic transmission aligning idler set, a bidirectional mechanical connecting rod full automatic aligning idler set, a conical aligning idler set, a sectional type variable friction aligning idler set and the like. The passive mechanical deviation rectifying devices can only rectify a single group of deviation generally, and more than two groups of deviation rectifying devices can not be rectified simultaneously easily because the deviation rectifying carrier roller groups corresponding to the parts with more or less protrusions of the belt deviation can start to operate to rectify the deviation. The deviation rectifying mechanism is as follows: only at the moment of belt deviation, the belt deviation protruding part applies transverse thrust to the deviation rectifying carrier roller group, and meanwhile, the deviation rectifying carrier roller group applies reverse acting force to the belt to rectify deviation. However, once the deviation rectifying carrier roller set rectifies the deviation of the belt, the acting force of the belt deviation rectifying part on the deviation rectifying carrier roller set is reduced and disappears, and the deviation rectifying acting force disappears instantly. Meanwhile, the belt continues to deviate, and the deviation rectifying carrier roller group repeats the action process. As a result, the belt is repeatedly deflected, the deviation rectifying carrier roller set is repeatedly rectified, the belt is not actually rectified, the safety risk of rubbing, abrasion and even damage caused by belt deflection is not eliminated, and the service life of the belt is obviously shortened.
