一种新型清扫装置在胶带卸载点的应用

带式输送机是煤矿煤炭运输的主要设备之一，为了保持胶带清洁，防止损坏带面，胶带卸载后必须对胶带表面进行清扫，故矿用带式输送机均安装了清扫装置。清扫装置对双滚筒传动带式输送机尤为重要，若胶带上的煤粉清扫不净，胶带受到损坏，或由于煤粉杂质粘结滚筒表面使胶带过怏磨损，对于钢绳芯胶带则会使钢绳芯断丝。目前杠带式输送机机头装配的清扫装置常见的有重锤式清扫器、弹簧式清扫器和固定式清扫器等。     

钢绳芯带式输送机胶带更换工艺

钢绳芯带式输送机胶带在长时问的运行过程中，由于磨损、老化会出现断绳，胶带面开胶、裂纹等现象，强度逐步下降，一旦胶带拉力安全系数低于设汁规定值时，必须进行胶带更换。由于井下钢绳芯带式输送机敷设距离长，作业环境条件又有限制，输送机胶带更换成了一项较为麻烦的工作。根据我公司矿井运输机胶带更换情况，一般更换一条2800多m的胶带．工期需要20天左右，给正常生产带来很大影响。因此，改进胶带更换工艺，缩短胶带更换工期，提高工作效率很有必要。下面对我公司三矿二水平钢绳芯带式输送机胶带更换中，在工艺方面进行的改进和取得成效作一论述和探讨。
