The invention belongs to the technical field of tree climbing mechanisms, and particularly relates to a manned electric tree climbing machine which comprises a driving unit, a frame unit, an electriccontrol unit, a tightening unit and a braking unit. When people use the tree climbing machine, a second arc-shaped holding mechanism is pulled open firstly, the tree is surrounded between the two rollers and the driving wheel, then the spiral spring is pushed to a stretched state through the push rod motor, the second arc-shaped holding mechanism is connected with a limiting hook of the spiral spring, the push rod motor returns, and the elastic force of the spring enables the rollers to be automatically adjusted according to the diameter of the tree to hold the tree. The driving motor is started, the tree climbing machine is made to ascend through the driving wheel and the other two rolling wheels, tree diameter changes in the ascending process can be compensated through elasticity of thespring, and braking is conducted through the electromagnetic brake when stopping is conducted. During descending, the machine descends slowly under the action of gravity by means of the reverse speedreduction function of the motor and the braking function of the electromagnetic brake.
本发明属于爬树机构技术领域,尤其设计一种载人电动爬树机,它包括包括驱动单元、车架单元、电控单元、收紧单元、制动单元。人们使用该爬树机时,先拉开第二弧形抱紧机构,将树围在两个滚轮与驱动轮之间,然后通过推杆电机将螺旋弹簧推至拉伸状态,将第二弧形抱紧机构与螺旋弹簧的限位钩相连,推杆电机回位,弹簧的弹力使滚轮根据树的直径自动调整以抱紧树木。启动驱动电机,依靠驱动轮及其它两个滚轮使爬树机上升,上升过程中的树径变化可通过弹簧的弹力补偿,停止时通过电磁制动器制动。下降时依靠电机反转减速功能,结合电磁制动器的制动功能,由重力使机器缓慢下降。
