清洁是针对启闭机的外表、内部及制动轮圆周面、电器接点、电磁铁吸合接触面和周围环境,定期进行清洁。启闭机房内外门窗一周清扫一次,场地上的工器具应及时整理,摆放整齐。 紧固是对压力油系统中的螺纹管接头、密封用压盖螺栓等进行紧固,防止松动造成漏油;对基础、法兰等各种定位螺栓、高强螺栓、钢丝绳压紧螺栓和吊具联接螺栓进行紧固,如松动会改变被联接零部件的受力和运动情况,并构成事故隐患。 调整: ①对轴瓦与轴颈、滚动轴承的配合间隙、齿轮啮合的顶、侧间隙、制动器闸瓦与制动轮之间的松闸间隙调整。 ②对制动器的松闸行程、离合器的离合行程、安全 限位开关的限位行程和闸门启闭位置指示行程进行调整。 ③对转动皮带、链条等松动及弹簧弹力大小的调整。④电流、电压、制动力矩、启闭机的流量压力、速度等 调整。 润滑:对启闭设备中有相对运动的零部件,均需保持良好的润滑。 Cleaning is aimed at cleaning, opening and closing of the hoist, the inside and the circumferential surface of the brake wheel, the electrical contacts, the contact surfaces of the electromagnet and the surrounding environment. The doors and windows of the hoist room are cleaned once a week, and the tools and tools on the site should be tidied up and placed neatly. Fastening is to fasten the thread pipe joint in the pressure oil system and the sealing bolt for sealing, to prevent loosening and oil leakage, and to fasten the foundation, flange and other positioning bolts, high strength bolts, wire rope press bolts and hoisting bolts, if loosening will change the force and movement of the connected parts. It constitutes the hidden danger of the accident. Adjustment: (1) the adjustment of the clearance between the axle bush and the axle neck, the rolling bearing, the top of the gear meshing, the side gap, the brake shoe and the brake wheel. 2. Adjust the brake loosening stroke, clutch clutch travel, safety limit switch limit stroke and gate opening and closing position indicating stroke. 3. Adjust the loosening of the belt and chain, and the spring elasticity. 4. Adjustment of current, voltage, braking torque, flow rate, pressure and speed of hoist. Lubrication: good lubrication is required for components with relative movement in the hoist equipment.
