The invention provides an adjustable hung tree anti-falling protection device which comprises a first clamping plate, a second clamping plate and a pressing plate which define a triangular structure, one end of the first clamping plate is rotationally connected with one end of the second clamping plate, a first sliding groove is formed in the other end of the first clamping plate, and a second sliding groove is formed in the other end of the second clamping plate; the two ends of the pressing plate are slidably connected into the first sliding groove and the second sliding groove correspondingly. The three clamping mechanisms are used for clamping a tree trunk, the tensioning mechanism is hung on a crane hook, two clamping mechanisms are connected into the first sliding groove and the second sliding groove in a sliding mode respectively, and the other clamping mechanism is fixed to the pressing plate; the tensioning mechanism enables the free ends of the first clamping plate and the second clamping plate to be close to each other and enables the pressing plate to slide towards the connected ends of the first clamping plate and the second clamping plate. The tree hoisting device has the effect of improving the problems that potential safety hazards exist in tree hoisting in the prior art, trees are damaged, and the survival rate of the trees is low.

    本发明提供了一种可调式吊树防坠落保护装置,其包括围设形成三角形结构的第一夹板、第二夹板以及压板,第一夹板的一端与第二夹板的一端相互转动连接,第一夹板的另一端开设有第一滑槽,第二夹板的另一端开设有第二滑槽,压板的两端分别滑动连接于第一滑槽和第二滑槽内;还包括三个夹持于树干的夹持机构和一个挂设于起重机挂钩的拉紧机构,其中两个夹持机构分别滑动连接于第一滑槽和第二滑槽内,另一个夹持机构固定于压板;所述拉紧机构使得第一夹板、第二夹板的自由端相互靠近,并使得压板朝向第一夹板、第二夹板相互连接的一端滑动。本发明具有改善现有技术中树木吊装存在安全隐患,且树木存在损坏,导致树木成活率较低的问题的效果。
