【摘要】：本课题调研的邯矿集团某矿主井,在提升容器箕斗上安装有钢丝绳张力监测系统,监测系统中的张力传感器和数据采集发射装置通过蓄电池进行供电。蓄电池的续航时间仅为48小时,每两天就要更换一次蓄电池。在与矿工交谈中发现,因为蓄电池供电缺陷人们普遍对钢丝绳张力监测系统产生了怀疑。因此,迫切需要一种在线充发电装置,满足矿井提升容器上监测装置的用电需求。通过现场调研其他矿井中安装的发电装置,结合矿井提升容器箕斗的运行规律,针对当前提升机充发电装置摩擦轮易磨损、旋转动能难提取、防爆电池充电时间长等方面进行研究,提出了两套不同原理的充发电装置设计方案。考虑到提升容器运行规律、罐道配合等实际工况条件,最终确定以弹簧预紧电机随动为基本原理,设计出适合主井箕斗的刚性罐道充发电装置。提升机刚性罐道充发电装置,主要由配有摩擦轮和防爆发电机的V形支架机构和压缩弹簧预紧机构两部分构成,采用摩擦轮与刚性罐道滚动摩擦的方式获得回转动能,通过带传动使防爆发电机发电。为了提高充发电装置的可靠性,开发了适用于矿井恶劣工况的摩擦轮,分析了摩擦轮打滑失效的原因;并提出了采用压缩弹簧预紧装置增大正压力,内层金属材料外层聚氨酯耐磨材料提高摩擦系数的方法,增强摩擦轮的可靠性;为了减少发电装置对主井箕斗运行的影响,提高安全系数,提出了双侧安装单侧发电的安装方式。最终结合三维建模软件Pro/E,根据绘制的二维图纸加工各个零部件并装配,得到了提升机刚性罐道充发电装置的样机,并将该样机安装在主井箕斗上进行了现场验证。
[Abstract]:In the main shaft of a mine of Handan Mine Group investigated in this subject, a wire rope tension monitoring system is installed on the skip of lifting container. Tension sensors and data acquisition emitters in the monitoring system are powered by batteries. The battery lasts only 48 hours and is replaced every two days. Because of the defects in battery power supply, people generally doubt the wire rope tension monitoring system. Therefore, there is an urgent need for a kind of on-line charging power generation device. To meet the electricity demand of the monitoring device on the mine hoist vessel, through investigating the power generating device installed in other mines, combining with the running rule of the hoisting vessel skip, aiming at the friction wheel of the current hoist charging power generating device is easy to wear and tear, In this paper, two sets of design schemes of charging and generating device with different principles are put forward in this paper, such as difficult extraction of rotational kinetic energy and long charging time of explosion-proof battery. Finally, based on the principle of spring preload motor following, the rigid tank channel charging power generating device suitable for main shaft skip is designed, and the hoist rigid tank channel charging power generating device is designed. It is mainly composed of two parts: V-shaped support mechanism with friction wheel and explosion-proof generator and pre-tightening mechanism of compression spring. The rotational kinetic energy is obtained by rolling friction between friction wheel and rigid tank track. In order to improve the reliability of the charging unit, the friction wheel suitable for the bad working condition of mine is developed, and the reason of the friction wheel sliding failure is analyzed. In order to reduce the influence of power generation device on the operation of main shaft skip, the method of increasing positive pressure with compression spring pretightening device and increasing friction coefficient of inner layer metal material outer polyurethane wear-resistant material are put forward, and the reliability of friction wheel is enhanced, in order to reduce the influence of power generation device on the operation of main shaft skip. With the help of the 3D modeling software Prop / E, the parts and components are machined and assembled according to the drawn 2D drawings, and the prototype of the rigid canister charging and generating device of the hoist is obtained. The prototype is installed on the main shaft skip for field verification.
