Follow-up self-adaptive control device

The invention discloses a follow-up self-adaptive control device. The follow-up self-adaptive control device comprises a frame, wherein a first lower friction wheel, a transition friction wheel, a second lower friction wheel, an upper friction wheel, a roller, a pressure wheel and a rope stop ring are mounted on the frame in sequence from left to right; a control rope penetrates through the rope stop ring after bypassing through the upper part of the first lower friction wheel, the lower part of the transition friction wheel, the upper part of the second lower friction wheel, the lower part of the upper friction wheel, the upper part of the roller and the lower part of the pressure wheel; the frame is hinged with a lever through a pin shaft; the first lower friction wheel, the second lower friction wheel and the roller are all mounted on the lever; the roller is fixedly provided with a centrifugal mechanism capable of reducing the rotating speed of the roller through a wheel shaft; and the lever is connected with a return spring. The follow-up self-adaptive control device can perform effective spreading control for linear belts, and can satisfy the spreading control requirements of the linear belts with different lengths through control ropes with the same lengths, so that the use effect is good, and the follow-up self-adaptive control device can be used in different altitude areas under different weather conditions.
