带式输送机是港口铁矿石等散料的主要运输机械,运行过程中输送带经常发生纵向撕裂事故,严重影响生产安全。分析了各种撕裂方法,提出采用安全光幕和拖板相结合的综合报警装置,输送带纵向撕裂及时报警并且制动输送机。该方法简单易行,实验效果好,非常适合港口现有带式输送机的进一步安全防护的配备。 Belt conveyors are the main transportation machinery for bulk materials such as iron ore ports. Longitudinal tearing accidents often occur on conveyor belts during the operation, which seriously affects the safety of production. Various methods of tearing are analyzed, a comprehensive warning device using a combination of a safety light curtain and a carriage is proposed, a longitudinal tear of the conveyor belt, a timely alarm and a brake conveyor are proposed. The method is simple and easy to operate with good experimental effect and is very suitable for the further safety protection of the existing belt conveyor in the port.
