Abstract

The utility model discloses a power line high tree obstacle clearing cutter, the cutting edge is a saw-tooth cutting edge; the traditional cutter needs to be changed into a form of a drag saw, so that labor is saved during use. Meanwhile, the problem that when the traditional obstacle clearing cutter is used for treating the tree obstacles at high positions, due to the fact that the moment is too small, and branches are mutually shielded, splitting and cutting actions cannot be carried out is solved. By using the edge-opening type barb structure, some tiny tree obstacles can be easily hooked and the branches can be cut off by pulling and pushing upwards, so that the work efficiency of obstacle clearing is improved, and the safety of power grid operation is effectively guaranteed. Moreover, the round hole arranged on the knife body is beneficial to the discharge of the saw dust, so that the obstacle removing effect is better. The handle of a knife that can splice formula also can adapt to the tree barrier operation demand of co-altitude not, makes the operation more convenient.

Description

Power line eminence tree barrier clears away cutter

Technical Field

The utility model relates to an instrument that power line patrolled and examined and maintained especially relates to a power line eminence barrier of trees clears away cutter.

Background

The power line is the life pulse of the power grid operation and is the 'life line' of the national civilization. The cleaning of tree barriers around the power line is important work for routing inspection of the power line, and plays a vital role in the complete operation of the power distribution network. However, since the power cables are erected at a place higher than the ground, particularly in a field environment, workers cannot use machinery to ascend and can only stand on the ground to operate. And when the aerial work, owing to receive the branch etc. to shelter from and the influence that moment diminishes, the wave of unfavorable traditional cutter is cut, and the high altitude obstacles removing is difficult to go on, and then has influenced the efficiency of obstacles removing.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a power line eminence tree barrier clears away cutter to solve among the prior art and clear away the problem that the barrier clearance inefficiency that the in-process used traditional cutter to cause at power line eminence tree barrier.

The technical scheme of the utility model is that:

a cutter for removing tree obstacles at a high position of a power line is characterized in that a cutter is fixed at the end of a cutter handle; the blade body of the cutter is of a C-shaped structure, the middle part of the blade of the cutter is a sawtooth-shaped blade, and the two ends of the blade towards the inside are of an edge-opening structure.

More than one round hole is uniformly arranged on the knife body close to the knife edge.

The handle of a knife adopts a splicing type insulating rod.

The top end of the cutter is provided with an opening.

The utility model discloses beneficial effect:

the utility model discloses a cutter is clear away to power line eminence barrier, the cutting edge uses the cutting edge of zigzag, when handling the barrier of tree of eminence, need chop traditional cutter and change the form of saw into, it is more laborsaving when using. Meanwhile, after the tree barrier is put on, the sharpening hooks at the two ends of the cutter body can cut and hook the tree barrier, and some small tree barriers can be easily removed. The work efficiency of removing obstacles is improved, and the safety of the operation of the power grid is effectively guaranteed. Moreover, the round hole that sets up on the blade is favorable to the discharge of saw-dust for the efficiency of removing obstacles is higher. The split type knife handle and the hole in the top of the knife body can adapt to the tree obstacle operation requirements of different heights and the problem of convenient carrying of the knife.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is the utility model discloses a cross-sectional view of insulating bar can be spliced to the handle of a knife.

Detailed Description

As shown in figure 1, the high tree obstacle clearing cutter for the power line consists of a cutter 1 and a cutter handle 2, wherein the cutter 1 is fixed at the end of the cutter handle 2; the blade body of the cutter 1 is of a C-shaped structure, the middle part of the blade of the cutter 1 is in a sawtooth shape, two ends of the blade extend outwards, and the blade body is of an inward opening type structure. For trees with large diameters in high altitude, the cutting effect of the sawteeth has more advantages than that of the traditional edging cutter.

The less trees of diameter in the high altitude can be colluded and dragged the cutting to the formula structure of opening the edge inwards at cutter 1 both ends, when having solved traditional cutter and using, because stand subaerial, moment undersize, in addition shield mutually between the branch and can't carry out the action of chopping.

The position on the knife body close to the cutting edge is uniformly provided with more than one round hole, which is beneficial to discharging the saw dust and quickening the clearing speed.

As shown in fig. 1, the tool holder is fixed on the tool body by using wing nuts and bolts. During the actual use, can select the cutter of suitable size as required to fix on the handle of a knife, increase the environment adaptability of cutter.

As shown in figure 2, the bottom end of the knife handle is provided with an internal thread, the top end is provided with an external thread, and the rod bodies are spliced together to meet the operation requirements of different heights. The handle is made of insulating material to prevent the electric shock of workers caused by mistakenly touching the lead during operation.

The top end of the cutter 1 is provided with the opening 3, so that the cutter can be conveniently hung on a hook of a tool box, and meanwhile, the cutter is convenient for workers to carry.
