摘要
带式输送机自它诞生以来,经过 200 多年不断完善和改进,已进入电力,
冶金,煤炭,化工,矿山,港口等各行各业之中。其机构简单,输送物料范
围广,输送量大,运距长,对线路适应性强,装卸料十分方便,可靠性高,
营运费低廉,基建投资省,耗能低,效率高,维修费少。
本设计为 DX 型钢丝绳芯式带式输送机,采用机头双滚筒驱动,在保证
滚筒不发生打滑的前提下来传递较大的功率,降低输送带的张力和提高使用
寿命。文中根据第二滚筒围包角用足,依此算出输送机的各种参数,进行结
构设计。由于倾角较大,按第二滚筒围包角用足进行等驱动功率单元法分配,
本设计采用 1:1分配,得出尾部张力最小,根据布置原则,张紧装置一般布
置在输送带张力最小处,所以本文采用重载车式张紧装置进行张紧。如今,
带式输送机正向长距离、高带速、大功率、大运量的大型化方向发展,使其
在煤炭行业得到广泛应用。

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 transporta
