It can be understood that the barrier orientation device firstly pulls the locking head 12 from the second end of the pulling hook 11 through the push-pull module to reach the unlocking position, the pulling hook 11 hooks the tree to be felled, and then the push-pull module pushes one end of the locking head 12 to be matched with the second end of the pulling hook 11 to reach the locking position, so that the tree to be felled is locked in a ring enclosed by the pulling hook 11 and the locking head 12, and the tree to be felled can be felled after the tree orientation control. This tree barrier orienting device need not fortune dimension personnel and climbs tree ligature direction rope, has stronger security and reliability, has reduced the operation risk, has improved work efficiency, has ensured fortune dimension personnel life safety.

Optionally, as shown in fig. 4 and 5, the tree barrier orientation device further includes a tightening mechanism 2 and an anchoring mechanism 3, and the orientation mechanism 1, the tightening mechanism 2 and the anchoring mechanism 3 are connected in sequence.

It should be explained that the orienting mechanism 1, the tightening mechanism 2 and the anchoring mechanism 3 are connected and matched in sequence to cope with the situation that trees below or near the corridor of the power transmission line are thicker or higher. Firstly, anchoring the anchoring mechanism 3 to a proper position on the ground in a control direction, connecting the orientation mechanism 1 with the anchoring mechanism 3 through the tightening mechanism 2, locking the trees to be felled in a ring formed by the draw hook 11 and the locking head 12 by the orientation mechanism 1, and adjusting the distance between the position of the anchoring mechanism 3 anchored on the ground and the position of the trees to be felled by the tightening mechanism 2. The cooperation of orienting mechanism 1, tightening mechanism 2 and anchoring mechanism 3 can realize treating the orientation of cutting trees and draw and drag control, need not fortune dimension personnel and climb tree ligature direction rope, simultaneously through anchoring mechanism 3 and ground anchor, the in-process of cutting the trees of waiting to cut need not fortune dimension personnel direct control, has improved work efficiency, has ensured fortune dimension personnel's life safety simultaneously.

In particular, the single use of the orienting mechanism 1 is generally suitable for the case where the power transmission line corridor or the nearby trees are thin and low.

It should be noted that, according to the principle of the rotation direction of the ratchet mechanism 23 being irreversible and the rotation being unidirectional, the rotating shaft 22 will be fixed at a specific position every time the rotating shaft 22 is rotated for a certain distance. When the rotating shaft 22 is rotated counterclockwise to a certain specific position, the first insulating rope 24 can wind a section of rope in the first insulating rope 24 around the rotating shaft 22, and since one end of the first insulating rope 24 is connected with the orienting mechanism 1, the first insulating rope 24 can pull the orienting mechanism 1, so that the oriented tightening of the tree to be felled is realized. Of course, in other embodiments of the invention, rotation of the shaft 22 in a clockwise direction may achieve directional tightening of the tree to be felled.

Thus fortune dimension personnel tighten up first insulating rope 24 through rotating the rocking handle, and then realize treating the directional tightening up of cutting down trees. In addition, when the length of adjusting first insulating rope 24 needs to be loosened, move the pawl and make pawl and ratchet separation, rotate pivot 22 to the length of the first insulating rope 24 of growing, after length adjustment is suitable, let go up the pawl, the pawl stops again on the ratchet under the shell fragment restoring force effect.
