Abstract
The invention discloses a broken belt capture device for a belt type conveyer, and belongs to the technical field of conveying belt protective devices. The broken belt capture device comprises a coal flow guide plat, a wedge groove, a wedge-shaped trolley, a friction box, a support and the like, wherein the wedge-shaped trolley and the friction box both adopt retractable roller structures; when the belt operates normally, the wedge-shaped trolley and friction box rollers for supporting the belt have the rolling friction function and extremely small resistance for the belt; when the belt is broken, the wedge-shaped trolley adopting a ratchet mechanism cannot roll; and under the driving of the belt, the rollers of the wedge-shaped trolley retract into the trolley, the wedge-shaped trolley slides downwards, simultaneously the rollers of the friction box retract into the friction box, the friction is changed from line contact to surface contact, the friction force is changed from small to large, finally the belt is captured, and accordingly the possibility of the secondary damage to the belt is low during belt capturing. The broken belt capture device for the belt type conveyer has a simple structure, stability, low possibility of the secondary damage to the belt, certain adaptivity and the like, as well as wide usability.
