摘    要
帶式輸送機自它誕生以來，經(jīng)過200多年不斷完善和改進，已進入電力，冶金，煤炭，化工，礦山，港口等各行各業(yè)之中。其機構(gòu)簡單，輸送物料范圍廣，輸送量大，運距長，對線路適應(yīng)性強，裝卸料十分方便，可靠性高，營運費低廉，基建投資省，耗能低，效率高，維修費少。
本設(shè)計為DX型鋼絲繩芯式帶式輸送機，采用機頭雙滾筒驅(qū)動，在保證滾筒不發(fā)生打滑的前提下來傳遞較大的功率，降低輸送帶的張力和提高使用壽命。文中根據(jù)第二滾筒圍包角用足，依此算出輸送機的各種參數(shù)，進行結(jié)構(gòu)設(shè)計。由于傾角較大，按第二滾筒圍包角用足進行等驅(qū)動功率單元法分配，本設(shè)計采用分配，得出尾部張力最小，根據(jù)布置原則，張緊裝置一般布置在輸送帶張力最小處，所以本文采用重載車式張緊裝置進行張緊。如今，帶式輸送機正向長距離、高帶速、大功率、大運量的大型化方向發(fā)展，使其在煤炭行業(yè)得到廣泛應(yīng)用。

Abstract
The belt conveyer with continue development and improvement has entered all trades and professions such as power, metallurgy, coal, chemical engineering, mine and port since being born for more than 200 years. Its construction is simple , it is broad to transport stock scope, it is big to transport quantity, the length of haul distance has strong adaptability for line, handling material 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.
