我厂的5吨轻型抓斗在起吊糖、煤过程中,经常发生断钢丝绳(φ14mm)事故,影响了正常工作。为此,我们对断绳的原因进行了分析,发现这主要是由于原糖或原煤在船仓里堆放如小山包,船仓肚大口窄,抓吊时,抓斗需斜放入仓底,使钢丝绳打折顶弯钢丝绳限位螺栓及管套,钢丝绳与抓斗顶上的钢板边缘相刮,造成钢丝绳刮伤起刺,直至断裂。据统计,工作中每隔3～4个班(一个班8小时)就出现断绳故障,有时甚至一个班出现几次。因此,如何消除钢丝绳刮边是解决断绳的关键。通过摸索和实践,我们设计了一种钢丝绳保护器,装在抓斗顶上(左右各一
The light grab of 5 tons of our factory often causes broken wire rope (φ14mm) accidents during lifting of sugar and coal, affecting normal work. To this end, we analyzed the reasons for the broken rope and found that it was mainly due to raw sugar or raw coal piled up in the boat bunker, Make the steel wire rope discounted The top bending steel wire rope limit bolt and pipe sleeve, the steel wire rope and the edge of the steel plate at the top of the grab scraping, causing the steel wire rope to scratch and prick until it breaks. According to statistics, work every 3 to 4 classes (a class 8 hours) broken rope failure appears, and sometimes even a class appeared several times. Therefore, how to eliminate the wire rope scraping is the key to solve the broken rope. Through exploration and practice, we designed a rope protector, mounted on top of the grab (left and right one
