The utility model relates to a pop-up plastic-lined pipe lining pulling claw, which comprises a lock head, a lock cover and a hook. The lock head is a hollow circular table-shaped structure with a lower opening. The shape of the lock cover is the same as that of the lock head. The lock cover coaxial cover is arranged on the outer edge of the lock head, and the upper end of the lock head and the lock cover are coaxially provided with a through hole, which is in two through holes. The hanging rod is coaxially worn with a hook, and the end part of the hanging rod is provided with a circular lock cap. The hook is embedded in the lock head and the lock cover, and is characterized in that a spring is arranged on the outer edge of the hook between the lock head and the lock cover. The utility model provides a hook sleeve spring between the lock head of the lining plastic pipe and the lock cover, which is easy to be ejected, and can increase the ejection force between the lock head and the lock cover, prevent the plastic pipe from being too stuck, cause the plastic pipe to be pulled out, and reduce the production efficiency.
【技术实现步骤摘要】
易弹出的衬塑管衬拉拽爪
本技术属于钢管生产设备领域,特别是一种易弹出的衬塑管衬拉拽爪。
技术介绍
衬塑管是以普通钢管作为基础,内衬化学性优良的热塑性塑料,经冷拉复合或滚塑成型,它既有钢管的机械性能,又有塑料管的耐腐蚀性能,缓结垢,不易生长微生物的特点,是输送酸、碱、盐、有腐蚀性气体等介质的理想管道。其中以PE衬塑管为应用最广泛,的介质工作温度:-25℃~+75℃(改性聚乙烯工作最高温度105℃);介质工作压力:正压2.5MPa,常温下负压为75KPa;耐腐蚀性:对非氧化性酸(如盐酸、稀硫酸、氢氟酸)、稀硝酸、碱和盐溶液都有良好的耐蚀性,但不耐浓硝酸、浓硫酸和其他强氧化剂的腐蚀。对有机溶剂、常温下一般耐腐蚀性良好。典型应用:适用于一般腐蚀性液体介质输送,更适用于生活用水和饮用冷热水的输送,输水时,不影响水质,符合食品卫生要求,高耐磨高密度聚乙烯管可广泛用于固液浆体如煤炭、矿砂的输送。广泛用于石油化工制品电力自来水环保等行业。现有的衬塑管生产都是采用塑料管向钢管内拉拽的方法实现了钢管的内侧,在拉拽过程中,必须使用拉拽爪勾拉住塑料管,由电机带动铁轨向钢管内拉入。
