一种适用于绞刀轴法兰螺栓孔的镗排装置
本技术涉及海洋工程结构物建造工装,更具体地说,涉及一种适用于绞刀轴法兰螺栓孔的镗排装置。
技术介绍
绞吸式挖泥船是利用转动着的绞刀绞松河底或海底的土壤,与水泥混合成泥浆,经过吸泥管吸入泵体并经过排泥管送至排泥区。绞吸式挖泥船施工时,挖泥,输泥和卸泥都是一体化,自身完成,生产效率较高。适用于风浪小、流速低的内河湖区和沿海港口的疏浚,以开挖砂、砂壤土、淤泥等土质比较适宜,采用有齿的绞刀后可挖黏土,但是工效较低。绞刀轴在绞刀挖泥作业时,传输扭矩较大,转速相对较高,因此绞刀轴法兰上所使用的螺栓一般为绞制孔螺栓,相对于绞刀轴法兰上螺栓孔的加工,传统工艺是采用手动绞刀逐一绞制,但该方式效率慢,若遇到高强度材质,就十分费力耗时,且手动绞刀规格是固定的,加工螺栓孔的尺寸也是固定的,尺寸单一,精度也较低,如加工螺栓孔不合格,则要重新买大一档尺寸的绞刀,重新进行绞孔,加之轴系绞孔时施工空间狭小,其他工种交叉作业多,工期一般比较紧张,因此需要一种适用于绞刀轴法兰螺栓孔连续镗孔的技术,用于代替现有纯人工的加工方式,并能够连续机械化镗孔作业。
