The invention provides a vertical chain traction facility and a traction method thereof. The device comprises a rack and two chain wheel transmission devices fixed to the rack. Haff tight holding devices are arranged between the two chain wheel transmission devices and provided with fastening oil cylinders, and the fastening oil cylinders control the haff tight holding devices to tightly hold a workpiece. Each chain wheel transmission device comprises a driving wheel and a driven wheel which are connected through a chain, wherein an upper traction block and a lower traction block are fixed tothe chain, and the haff tight holding device is arranged between the upper traction block and the lower traction block. The chain wheel transmission devices drive the haff tight holding devices to move in the vertical direction through the upper traction blocks and the lower traction blocks. Haff outer die tight holding mechanisms are provided for the first time to drag a composite pipe. The device is provided with a self-locking mechanism, it can be ensured that the haff outer die tight holding devices lock the pipe, two traction facilities alternately work, and it is guaranteed that the pipestably moves.
本发明提供了一种竖直链条牵引设备及其牵引方法,所述的装置包括机架以及固定在机架上的两个链轮传动装置,两个链轮传动装置之间设置有哈夫抱紧装置,哈夫抱紧装置上设置有紧固油缸,紧固油缸控制哈夫抱紧装置抱紧工件;所述的链轮传动装置包括通过链条连接的主动轮和从动轮,链条上固定有上牵引块和下牵引块,哈夫抱紧装置安装在上下牵引块之间,链轮传动装置通过上下牵引块带动哈夫抱紧装置沿竖直方向运动。本发明首次提出哈夫外模抱紧机构牵引复合管材,该装置自带自锁机构,能够确保哈夫外模抱紧装置锁紧管材,双套牵引设备交替工作,保证管材稳定移动。
