Analysis of the characteristics of the spiral tightening device of the belt conveyor
The spiral tightening device of the conveyor belt is a fixed tightening device. The structure is simple and easy to manufacture. It is mainly composed of tightening screws, nuts and sliders. Its working principle is to fix the tail wheel directly on the slide with tightening nuts, rotate through the screw to drive the tail wheel to move back and forth, to achieve the purpose of tight tape, so that the tape has sufficient tension to ensure that the tape and the roller tube and the drum Do not slip.
The characteristics of the belt conveyor conveyor band spiral tighter device are:
(1) The tightening force is small and the tightening itinerary is short; the low energy consumption of the spiral tightening device is mainly depends on the size and length of the diameter of the screw. Because it is installed on the tail wheel frame, it is limited by the tail wheel bracket, the screw screw screw The diameter and length are generally not large, so the tightening itinerary is short and the tightening force is also less. It is not suitable for the long -distance band conveyor installed with the tightening force.
(2) The structure is simple and easy to operate; when the tape is needed, you only need to rotate the screw with a wrench. The operation is simple, fast, and the workers’ labor intensity is small and high efficiency. The band conveyor with a slight bias phenomenon can tighten the screw by rotating only one side, adjust the parallel angle of the tail wheel and the header, and mix the tape.
(3) The installation size is small and full of space; the shape of the screw and the nut is usually small, the manufacturing is difficult, the processing is easy, and it is installed on the tail wheel bracket. Therefore, the whole machine cost is low.
(4) The cost of running is small; because the screw has self -locking characteristics, its use performance is stable and reliable, and it has good adaptability to the external environment. The price of tightening the spare parts is not expensive, the maintenance replacement time is short, the maintenance workers’ labor intensity is small, so the efficiency is high and the operating cost is low.
