Belt sway switch plays a very important role in conveying system, widely used in metallurgy, coal, cement building materials, mining, electric power and other industries.This paper mainly studies mine belt sway switch, through comprehensive analysis and research, the final design of a universal thawing for coal mine two-level belt sway switch. Belt sway switch is used to detect the amount of belt deviation of belt conveyor. It is a safety protection device that can automatically alarm and stop the machine when the belt deviation occurs.belt sway switch has two levels of angles, commonly used are: the first level of Angle is: 10, 12, 20, the second level of Angle is :30, 35, 45. When the conveyor belt deviation is serious and reaches the level 2 switch Angle, the switch will send out the stop signal to realize the automatic shutdown of the conveyor belt deviation fault. When the belt conveyor operates normally after the off-tracking fault is eliminated, the switch vertical roller can be automatically reset and return to the initial state.
Belt sway Switch used for normal belt conveyor: two levels of wandering underground, ropeway support belt conveyor, the ship handling system: stacking or feeding conveyor: tilt and school conveyor: crane, dig binder, lift arm spacing: skirt feeder or conveyor: heavy detection belt running deviation, the limit switch is the realization of automatic tape machine control alarm and shutdown protection device. Widely used in metallurgy, coal, cement building materials, mining, power, port, metallurgy, chemical industry and other fields of a variety of belt conveyor equipment.
2. Status of belt sway switch
Belt sway g switches are common type, connection cavity type, address code.
(1) the common type is the two-stage belt sway switch mentioned above;
(2) the connect wire type belt sway switch is equipped with a waterproof connection cavity on the basis of the common type of deviation switch. The field control cable can be directly pressed into the connection cavity to eliminate the fault caused by damp and virtual connection of the cable joint.
(3) address coding off-tracking switch integrates XLline technology on the basis of common off-tracking switch to realize address coding function.It is suitable for long belt conveyor to be used as remote monitoring equipment in the field.
