The characteristics of the helical tension device is:
(1) the tension force is small, taut trip short;Screw tension device adjustment ability mainly depends on the size of the screw diameter and length, because it is installed in the tail wheel rack, restricted by the tail wheel bracket, screw diameter and length is not big, so taut trip is shorter, tensioning force is small, not suitable for installation on long distance belt conveyor tensioning force.
(2) simple structure, easy to operate;When need tensioning tape, just using a wrench screw rotate, operation is simple, quick, workers labor intensity is small, high efficiency.Phenomenon of the belt conveyor, the slight wandering through rotating side only tighten the screw, adjust the Angle of the tail wheel and the wheel head parallel, adjusting to tape.
(3) the installation size, make full use of space.Screw, nut are generally small, the overall size manufacturing difficulty is small, easy processing, and installed on the tail wheel bracket, made full use of space, save the equipment cover an area of an area, and low cost.
(4) running cost small;Because the screw with self-locking feature the use performance is stable and reliable, and good adaptability to external environment, long service life, even in the dust, mud more bad working conditions can be normal use.Tension device spare parts price is not expensive, repair replacement time is short, the maintenance workers labor intensity is small, and high efficiency, low operating cost.
