一旦輸送帶在使用過程中發(fā)生斷裂，輸送帶將在自身重量和煤重的強大作用下加速下降幾十米或幾百米。電纜及電器設備及小零件，造成輸送帶及物料大量堆積而停產。從對大量皮帶斷裂事故的分析可以看出，皮帶輸送機皮帶斷裂的原因如下。
Once the conveyor belt breaks during use, the conveyor belt will accelerate to drop by tens or hundreds of meters under the strong effect of its own weight and coal weight. Cables, electrical equipment and small parts cause a large amount of accumulation of conveyor belts and materials and stop production. From the analysis of a large number of belt fracture accidents, it can be seen that the causes of belt fracture of belt conveyor are as follows.
1、齒輪減速器損壞，液力偶合器噴液或電機反轉。
1. The gear reducer is damaged, the fluid coupling sprays or the motor reverses.
2、輸送帶接頭質量問題。輸送帶接頭分為機械接頭和硫化接頭。機械接頭的質量遠不如硫化接頭，所以現(xiàn)在很少使用。就硫化接頭而言，如果未按要求控制硫化溫度和硫化壓力，則溫度和壓力在硫化板上分布不均勻，溫度和壓力的保持時間設置不合理，使用不合理的材料會影響硫化過程。影響。
2. Conveyor belt joint quality problem. Conveyor belt joints are divided into mechanical joints and vulcanization joints. The quality of mechanical joint is far inferior to that of vulcanized joint, so it is rarely used now. For vulcanized joints, if the vulcanization temperature and pressure are not controlled as required, the temperature and pressure are unevenly distributed on the vulcanized plate, the holding time of temperature and pressure is set unreasonably, and the use of unreasonable materials will affect the vulcanization process. influence.
3、運輸過程中由于其他東西的介入，運輸負荷突然增加。如大塊煤矸石或其他特別大的物體突然混入正在運輸?shù)拿禾恐小?/div>
3. During the transportation, due to the intervention of other things, the transportation load increases suddenly. For example, large coal gangues or other particularly large objects suddenly mix into the coal being transported.
4、啟停時應力變化大。帶式輸送機的啟停也會導致輸送帶斷裂。一般情況下，建議是在空載下啟動輸送機。
4. The stress changes greatly during startup and shutdown. The start and stop of the belt conveyor will also cause the belt to break. Generally, it is recommended to start the conveyor under no load.
5、輸送帶本身質量不夠好，輸送帶使用壽命過長，輸送帶長期超載，日常維護不到位。
5. The quality of the conveyor belt itself is not good enough, the service life of the conveyor belt is too long, the conveyor belt is overloaded for a long time, and the daily maintenance is not in place.
6、物料分布不均，輸送帶跑偏。帶式輸送機有空載段和超載段，造成輸送帶受力不均。
6. Uneven distribution of materials and deviation of conveyor belt. Belt conveyor has no-load section and overload section, resulting in uneven stress on the conveyor belt.
山東輸送帶皮帶廠家認為為了防止這些原因造成的皮帶斷裂事故，除了人工檢修和維護外，沿輸送機布置皮帶斷裂保護裝置尤為重要。因為它可以避免意外事故，隨時待命。輸送帶正常工作時，不影響物料輸送。當皮帶斷裂事故發(fā)生時，它會立即行動，迅速抓住斷裂和滑動的輸送帶。
Shandong conveyor belt manufacturers believe that in order to prevent belt fracture accidents caused by these reasons, in addition to manual repair and maintenance, it is particularly important to arrange belt fracture protection devices along the conveyor. Because it can avoid accidents and stand by at any time. When the conveyor belt works normally, it does not affect the material conveying. When a belt breakage accident occurs, it will act immediately and quickly grasp the broken and sliding conveyor belt.
