我矿使用的2400×1200重型板式给矿机,自1973年5月投产以来,一直存在送料带跑偏问题。由于该机无调整装置,发生跑偏后,无法消除,曾导致多次拉弯机架或刮掉槽板的设备事故,1983年和1985年两次大修,也未能彻底解决。平时为处理跑偏,经常停机修理,影响生产,造成很大的经济损失。我们曾采取过不少技术措施,如增设挡轮装置,加简易的调偏装置和刮板式清扫器等,但都未彻底解决跑偏问题。生产车间甚为焦虑,因此于1985年底列为我矿技术攻关项目之一。
The 2400 × 1200 Heavy Duty Plate Feeder, which I used in the mine, has been running the problem of feed belts since it was put into operation in May 1973. As the machine without adjustment device, after the deviation occurs, can not be eliminated, has led to repeatedly pull the rack or scrape the slab equipment accident, two major overhauls in 1983 and 1985, also failed to completely solve. Usually to deal with deviation, often downtime repair, affecting production, causing great economic losses. We have taken a number of technical measures, such as the addition of wheel stop devices, plus simple adjusting device and scraper cleaner, etc., but did not completely solve the deviation problem. Production workshop is very anxious, so at the end of 1985 as mine mine technology research project.
