带式输送机机头硐室改造及远距离卸载臂的研制

Reconstruction of Belt Conveyor Driving Head Chamber and Research & Development on Long-Distance Unloading Boom

针对综采工作面运输坡度较大及巷道设计不平整等引发的带式输送机重载无法启动、输送带打滑、电机温度升高等问题,提出了以带式输送机机头结构为基准,设计带式输送机机头硐室并对机头卸载部进行改造的新方案,即倾斜落差式机头硐室和远距离卸载臂,通过降低带式输送机机头硐室安装平台的施工高度,从而降低带式输送机机头大架缓冲段的坡度,实现了大架传动部分降低高度安装而不影响带式输送机运行性能,同时通过实际工作面的应用验证了其实用价值。

According to the belt conveyor hard to start due to the heavy load, the slipping of the conveying belt, temperature rising of the electric motor and other problems caused by the high conveying slope of the fully mechanized coal mining face and the unleveled designed gateway, based on the driving head structure of the belt conveyor as basis, the driving head chamber was designed for the belt conveyor and a new plan of the reconstruction was provided for the discharging unit of the driving head. Thus the inclined drop driving head cham- ber and the long distance discharging arm, with the reduction of the manufactured height of the installed platform in the driving head chamber of the belt conveyor, thus could reduce the slope of the buffer section in the large framework of the driving head of the belt con- veyor and the height of the large framework driving section could be reduced and the operation performances of the belt conveyor could not be affected. Meanwhile the application to the actual coal mining face had confirmed the applied value.
