混凝土振捣器有几种?怎样使用? | 2012-3-31 9:47:00
混凝土振捣器有几种?怎样使用?
混凝土振捣器按混凝土传播振动的作业方式不同,可分为插入式内部振捣器、附着式外部振捣器、平板式表面振捣器及振动平台等四类。
使用混凝土振捣器要注意:
(1)插入式振捣器电动机电源上,应安装漏电保护装置,熔断器选配应符合要求,接地应安全可靠。电动机未接地线或接地不良者应严禁开机使用。
(2)操作人员应掌握一般安全用电常识。操作振捣器作业时,应穿戴好胶鞋和绝缘橡皮手套。
(3)振捣器停止使用时,应立即关闭电动机,搬动振捣器时,应切断电源,以确保安全。不得用轮管或电缆线拖拉,扯动电动机。
(4)电缆线上不得有裸露之处,电缆线必须放置于干燥、明亮处,不允许在电缆线上堆放其它物品,也不允许车辆在其上通行,更不许用电缆线吊挂振捣器等物。
(5)振捣器作业时,软管弯曲半径不得小于50cm,且软管不得有裂纹。
(6)振捣器启振时,必须由操作人员掌握,不得将启振的振捣棒平放在钢板或水泥板等坚硬物上,以免撞坏发生危险。
(7)严禁用振捣棒撬钢筋和模板,或将其当锤子使用,操作时勿使振捣棒头夹到钢筋里或其他硬物而受到损坏。
(8)用绳拉平板振捣器时,拉绳应干燥绝缘,移动或转向时不得用脚踢电动机。振捣器与平板应保持紧固,电源线必须固定在平板上,电源开关应装在手把上。
(9)在一个物件上同时使用几台附着式振捣器工作时,所有振捣器的频率必须相同。
(10)作业后,必须做好清洗、保养工作。振捣器要安放在干燥处。
