随着世界经济一体化的进一步加剧,我国煤矿机械行业面临着前所未有的机遇和挑战.相关企业也是面临激烈的市场竞争,当前的出路是学会在市场经济体制下的企业运作规则,以技术创新和可靠性技术提高煤机产品在国内外市场的竞争力,在竞争中求得生存与发展.
Nine-roller leveller is taken as example,whose structural characteristics and working principle were introduced in the paper.The leveller is composed of the frame,rollers,movable crossbeam,screwdown and rotation mechanism,main drive system,lubrication system,electrical control system,etc.This paper focuses on the structural characteristics of each parts of the nine-roller leveller and its application in steel plate flattening.
液压支架是矿用设备的主要部件,在井下起到支护作用。针对其产量大、加工精度低的特点,设计两款专机进行液压支架结构件整体镗孔的加工。本文介绍了掩护梁镗孔专机、顶梁镗孔和底座镗孔专机的设计、制造和安装,这两款专机结构相对简单,按照产品特点设计后满足了产品的加工要求,使用后提高了生产效率,节省了加工成本。
支护问题一直是困扰煤矿安全生产、产量和效率的重要问题。液压支架电液控制系统的出现和发展,从根本上改变了井下工作条件,并为煤炭的高效高产迅速提高奠定了基础。液压支架电液控制系统是目前液压支架最先进的控制方式,是综合运用计算机、通信网络、传感、机械、电子、控制等技术于一身的一项高技术产品。
By analyzing the structure and craft characteristics of the shield beam of a hydraulic support,we put forward adopting special machine to process the shield beam,and designed a special machine.The practice has verified the feasibility of the machine and the corresponding processing technology.
The influencing factor of cancel the remnant stress was researched,and about hydraulic support connecting bar structure use the way of harmonic wave ageing.The process technical parameter which use the way of harmonic wave cancel the remnant stress was advanced.The situation of connecting bar ageing which about the counterpoised by the stress was checked and assessed.The economic benefit between the spectrum harmonic wave ageing and the traditional heating aging was analysed.
