Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a high-safety wood lifting device. Background Art

[0002] After peeling, the wood needs to be lifted. Since the wood is cylindrical, the existing wood is generally lifted by hanging ropes at both ends of the wood. This lifting method is time-consuming and labor-intensive, and has low lifting efficiency and cannot meet the needs.

[0003] In the prior art, an authorized patent with announcement number CN220376086U discloses a wood processing lifting device, including a lifting cylinder, which includes a supporting arc frame and limiting rings symmetrically fixed at both ends of the supporting arc frame. A plurality of ropes for tightening the wood are fixed on the supporting arc frame, and a lifting ring is fixed on the top of the limiting ring. First, multiple woods are stacked on the supporting arc frame, and both ends of the wood are exposed outside the limiting ring. The wood can be initially clamped by the limiting ring, and then the wood can be further tightened by multiple ropes to prevent the wood from axial movement, thereby ensuring the stability of the lifting; the method of lifting multiple woods at the same time greatly improves the lifting efficiency and saves time and effort.

[0004] When the above technical solution is used, the following shortcomings still exist: it is difficult to ensure that the wood of the above lifting device fits exactly with the limit ring, it is difficult to ensure the stability of the wood during the lifting process by only using multiple cables, the wood is easy to tilt and fall, and there is a safety hazard, and the loading and unloading of wood are cumbersome and inconvenient. In this regard, we propose a high-safety wood lifting device to solve the above problems. Utility Model Content
