【正文】 al is very convenient, reliability is high , it can reduce investment in basic construction, high efficiency, low maintenance cost. The design is DX model core type belt conveyer of wire rope, the machine header adopts two cylinder drives ,in guarantee cylinder do not occur the prerequisite with slippery dozen transmit greater power, reduce raising the tension of belt conveyer and improve service life. In writing according to second cylinder surround bale angle use enough, according to this various parameters that make conveyer finally, carry out structural design. Since inclination is greater, according to second cylinder wait for drive with foot power unit law distribution, this design adopts 1: 1 is distributed , it is minimum to reach tail tension, basis arrange principle, tension station arranges normally, is in the tension minimum place of conveyer belt , so, this paper use the burden vehicle tension equipment to tighten. Now belt conveyer’s development towards to long distance, high belt speed, great power and high transportation, and the advantage of this kind of conveyer realizes easily, make extensive application in coal industry. Keyword Belt conveyer two cylinder drive tight III 目 錄 摘 要 ......................................................... I Abstract ........................................................
