The invention discloses a connecting structure of a lifting device for a forestry crane. The connecting structure comprises a guide groove, a first screw rod, a second screw rod, an adjusting moving device, a first moving seat, a first transmission locking mechanism, a first steel wire reel, a second steel wire reel, a second transmission locking mechanism, a first spline shaft, a first motor and a second moving seat. According to the wood hoisting device, the first air cylinder extends to drive the first moving seat to move transversely as a whole, the first air cylinder shortens to drive the second moving seat to move transversely as a whole, the distance between the first steel wire reel and the second steel wire reel can be adjusted, and therefore the wood hoisting device is suitable for hoisting wood of different lengths; the hoisting stability and reliability are improved, and the hoisting efficiency is improved; when a piston rod of a first air cylinder is located in the center, a first driving gear can be meshed with a first driven gear and a second driven gear at the same time, so that a first screw and a second screw can rotate together, and the requirement for translation of wood after hoisting is met.
本发明公开了一种林业起重机用起升装置的连接结构,包括导槽、螺杆一、螺杆二、调节移动装置、移动座一、传动锁紧机构一、钢丝卷筒一、钢丝卷筒二、传动锁紧机构二、花键轴一、电机一和移动座二;本发明中通过气缸一的伸长能够驱使使移动座一整体横向移动,而通过气缸一的缩短则能够驱使移动座二整体横向移动,也就能够对钢丝卷筒一和钢丝卷筒二之间的距离进行调节,从而适用了不同长度木材吊装的需要,也就提高了吊装的稳定性和可靠性以及提高了吊装的效率;本发明中当气缸一的活塞杆处于中央位置时,则能够使主动齿轮一同时与从动齿轮一和从动齿轮二一起啮合,从而能够使螺杆一和螺杆二一起旋转,也就满足了吊装后木材平移的需要。
