摩擦压砖机是耐火材料生产的主要成型设备,在使用过程中,丝杆可能产生裂纹,而这裂纹往往不易检查出来,因而曾多次发生摩擦压砖机丝杆断裂、滑块下落压手事故。为了防止此类事故,包头市耐火材料厂一位老工人采取在丝杆上部(退刀槽处)放一内嵌轴承的横担(见附图),在滑块的两侧各用一拉杆将横担和滑块连接起来,一旦丝杆断裂,两拉杆即可把滑块拉住,从而可以防止滑块下落,避免压手事故的发生。 Friction brick pressing machine is the main molding equipment for the production of refractory materials. In the process of using, the screw rod may crack, and the crack is often not easy to check out, so it has repeatedly friction friction brick screw break, slider drop pressure hand ACCIDENT. In order to prevent such accidents, an old worker in Baotou Refractory Material Factory took a cross bearing (see attached drawing) with an embedded bearing in the upper part of the screw (at the undercut), and used a pull rod on each side of the slider The cross arm and the slider connected, once the screw break, the two pull rod can pull the slider, which can prevent the slider to fall, to avoid the occurrence of pressure hand accidents.
