The outer ring is sleeved on the outer ring of the inner ring, the inner ring rotates relative to the outer ring, the outer ring of the inner ring is provided with a groove, the outer ring is provided with a plurality of through holes, the through holes are communicated with the inner ring from the outer ring of the outer ring, the inner ring is connected with the outer ring through a pin shaft, and the pin shaft extends into the groove which directly extends into the outer ring of the inner ring from the outer ring of the outer ring.

The outer ring is provided with a quincuncial joint which is used for being connected with the insulating operating rod.

The insulation operation rod is a telescopic insulation operation rod.

In summary, compared with the prior art, the invention has the following advantages:

According to the logging and rope winding method disclosed by the invention, the traction rope can be fixed on the ground only through the insulating operation rod, so that the climbing operation in a wet and slippery forest is avoided, the safety and convenience are very high, the field use effect is very obvious, the whole process can be completed in only 3 minutes, and the work efficiency is improved by 5 times. The portable tree trunk is portable by only carrying a telescopic insulating operating rod smaller than 1.5 m and an auxiliary tool smaller than 300mm in diameter, and particularly the portable tree trunk is more portable in thick tree forests. The electric power line corridor maintenance and cutting operation can be achieved daily. The method can also be applied to the bamboo felling operation of corridor trees of urban distribution lines, and has strong universality.

Detailed Description

The present invention will be described in more detail with reference to examples.

Example 1

The utility model provides a logging haulage rope fixing method, provides a rope winder, including having inner loop and the outer loop 2 of opening, the outer loop cover is in the outer lane of inner loop, and inner loop 1 rotates relative outer loop, the inner loop still include a little ring 3, the both ends point of this little ring starts in the opening both sides of inner loop and with the inner loop a common opening, be provided with fixed orifices 4 of fixed haulage rope on little ring central point, be provided with on the outer loop and be used for the plum blossom type joint connecting device 21 that links to each other with insulating action bars. The outer ring is sleeved on the outer ring of the inner ring, the inner ring rotates relative to the outer ring, the outer ring of the inner ring is provided with a groove 11, the outer ring is provided with a plurality of through holes 22, the through holes are communicated with the inner ring from the outer ring of the outer ring, the inner ring is connected with the outer ring through a pin shaft, and the pin shaft extends into the groove of the outer ring from the outer ring of the outer ring to directly reach the outer ring of the inner ring. When the traction rope is used, the traction rope is fixed on the traction rope fixing hole of the small ring, then the whole rope winding device is installed on the insulation operation rod, the insulation operation rod is utilized to lift the rope winding device to the traction rope fixing point, the small ring is clamped into the trunk, then the insulation operation rod is utilized to push the rope winding device, the outer ring drives the inner ring to move, the moving inner ring drives the small ring connected with the inner ring to move, the small ring circumferentially rotates along the trunk, so that the traction rope is wound on the trunk, the insulation operation rod is retracted, the traction rope is led to the ground, the traction rope on the rope winding device is removed, the traction rope head is bound with the movable rope buckle on the main traction rope, the traction rope is pulled, and the rope buckle is led to the trunk to fix the traction rope.
