The invention relates to a wood hoisting grab bucket and a wood hoisting method adopting the grab bucket. The wood hoisting grab bucket comprises an upper bearing beam, a lifting pulley, a lower bearing beam, bucket bodies, a supporting rod, a connecting rod and an opening and closing device, a pressing plate is arranged below the lower bearing beam and connected with the lower bearing beam through a pressure applying device, an annular grabbing space surrounding wood is formed when the two pairs of bucket bodies are closed, the pressing plate is located on the upper middle portion of the grabbing space, and the wood grabbed by the grab bucket is extruded, so that the wood is prevented from escaping. The wood hoisting method comprises the steps that wood is horizontally transferred to a middle transfer frame through a wood loader, and a wood stack is formed; and then the wood stack is grabbed through the wood hoisting grab bucket, and after the wood stack is hoisted to the target position, the bucket is opened to put down the wood stack. The wood hoisting grab bucket can effectively improve the safety of wood hoisting and reduce the labor intensity of workers.

    本发明涉及到一种木材吊运抓斗以及采用该抓斗的木材吊运方法。木材吊运抓斗包括上承梁、提升滑轮、下承梁、斗体、撑杆、连杆、开闭装置,下承梁的下方设置有一块压板,压板通过施压装置与下承梁连接,两对斗体闭合时形成环抱木材的环形抓料空间,压板位于该抓料空间的中上部,对抓斗抓住的木材进行挤压,避免木材窜出。木材吊运方法为先用木材装载机将木材水平转移至中间转移架,形成木材垛;再采用上述木材吊运抓斗抓取木材垛,将木材垛吊运至目标位置后,开斗放下木材垛。本发明可有效提高木材吊运的安全性,降低工人的劳动强度。
