1. Injury accidents occur mainly due to illegal operations.
① Override the belt conveyor in violation of regulations.
② Take the belt conveyor illegally.
③ Although some belt conveyors can take people, the offside protection device is not perfect.
④The belt conveyor is broken or torn due to poor management.
2. Occurrence of belt fire accident. In some accidents, there are many casualties due to belt fire accidents. There are three factors:
First, there is no complete protection device, scribble maintenance, coupled with external environmental reasons, resulting in friction between the belt and the drive drum, causing a fire;
Second, during use, unqualified materials, such as fluid couplings, were used, resulting in fuel injection fire accidents;
Third, the flame-retardant belt was not used in accordance with relevant regulations, which caused friction and fire.
3. The belt slipped or slipped. The slippage of the belt is due to the insufficient anti-skid facilities, the large inclination angle of the inclined road, and the overload phenomenon, which leads to the occurrence of accidents; the belt slippage is mostly caused by heavy belt load or loose belt or belt jam.
4. Effective measures to prevent accidents:
First, the technical improvement measures:
①In order to prevent the belt from catching fire, it is possible to add an automatic shutdown to the belt conveyor, or to automatically spray water after the addition of slipping heating, which has a cooling effect.
②Calculate the inclination angle of the conveyor inclined lane to see if the conditions for the belt to not slide down are met. If the conditions are not met, the belt slide down control equipment can be added.
Second, the improvement in production management
