Telescopic anti-displacement tree felling ladder
The invention discloses a telescopic anti-displacement tree felling ladder. The telescopic anti-displacement tree felling ladder comprises a ladder body and is characterized in that the ladder body comprises a hollow pipe, pedals are fixedly connected to the inner side of the outer wall of the hollow pipe, pulleys are symmetrically and fixedly connected to the two ends of the upper portion of thehollow pipe, ropes are arranged at the joints of the ends of the two pulleys and the hollow pipe, and the two ends of each rope extend out of the corresponding pulley. According to the telescopic anti-displacement tree felling ladder, a ratchet wheel type cloth belt tightener is installed at the bottom of the ladder and used for fixing the distance between the ladder and a tree to ensure that theladder cannot slide off, the two ends of the upper portion of the ladder are each provided with the corresponding fixing pulley, the ropes penetrate through the fixing pulleys, the tree is sleeved with the ropes on the ground; the ropes are tightened when the ladder stretches to the proper height, the ladder is firmly tied on the tree, the stability of the tree felling ladder during use is improved, a protective pad is fixed at the bottom of the hollow pipe so that displacement during use of the tree felling ladder can be prevented, and dangers are avoided.
本发明公开了一种伸缩式防位移伐树梯，包括梯身，其特征在于：所述梯身包括中空管，所述中空管的外壁内侧固接有踏板，所述中空管的上方两端对称固接有滑车，两个所述滑车的端处与中空管的连接处设有绳子，绳子的两端由滑车伸出。该伸缩式防位移伐树梯，在梯子的底部安装棘轮式布带收紧器，用于固定梯子与树的距离保证梯子不会滑落，梯子的上部两端各有一个固定滑车，并穿入绳子，在地面时用绳子把树木套住，梯子伸到合适高度时两侧收紧绳子，就将梯子牢固的拴在树木上，增加伐树梯使用时候的稳定性，而且中空管的底部固定有防护垫，可以防止使用伐树梯的时候位移，避免造成危险。
