Abstract

The utility model discloses an auxiliary draw hook for clearing tree and bamboo obstacles on a power transmission line, which comprises a hook head and an insulating hook handle. The hook head is provided with an inserting hole. The front end of the hook handle is provided with an inserting rod capable of being inserted into the inserting hole. The hook head is connected with an insulating pull rope. When the auxiliary draw hook is in use, the inserting rod is inserted into the inserting hole by an operator from a safe distance. The draw hook is then delivered to to-be-chopped branches and leaves through the hook handle. After that, branches and leaves can be chopped by the operator through pulling over the branches and the leaves with the pull rope. In this way, the potential electrocution risk of the operator is prevented, and the damage to the power transmission line or equipment due to chopped branches and leaves hit onto the power transmission line or the equipment can also be avoided. In addition, a plurality of draw hooks are adopted to hook branches more easily. The inserting rod is curved to be directly used as a draw hook to chop branches and leaves which are easy to hook. In addition, the length of the hook handle can be adjusted according to actual conditions. Therefore, the auxiliary draw hook is convenient to use.

Description

The auxiliary drag hook of transmission line tree bamboo obstacle cleaning

Technical field

The utility model relates to electric power maintenance technical field, particularly a kind of aid of safeguarding for transmission line inspection.

Background technology

When tree bamboo shoot and leaf growth is near the cabling space of transmission line or power equipment facility time, easily cause the short circuit of circuit and equipment, under wind and rain weather, also may topple over electric wire, the damage equipment of breaking, cause power failure, for ensureing electric power regular supply, usually need near tree bamboo branches and leaves circuit and equipment to cut down.

At present, normally maintainer directly cuts down transmission line and the in-plant tree of equipment bamboo branch, and this mode not only exists the potential safety hazards such as electric shock, and is fallen and easily damage electric wire and equipment by the branch after breaking apart by chopping.

Therefore, need to explore that a kind of energy is auxiliary sets the instrument that bamboo is removed, can support personnel's safety when this work is carried out, also can support equipment safety.

Utility model content

In view of this, the utility model provides a kind of transmission line tree bamboo obstacle cleaning auxiliary drag hook, between the insulation neck of hook of this drag hook and drag hook, adopt on connected structure and drag hook and be connected with stay cord, operating personnel can deliver to drag hook outside safe distance needs felling tree bamboo branches and leaves position, extract again the neck of hook out, by stay cord, draw over to one's side and cut down, solved the technical problem that existing Cutting method exists potential safety hazard and easy damage equipment.

The utility model solves the problems of the technologies described above by following technological means:

The auxiliary drag hook of transmission line tree bamboo obstacle cleaning of the present utility model, comprises gib head and the insulation neck of hook, on described gib head, is provided with spliced eye, and the setting of described neck of hook front end can be inserted the shank of spliced eye, is connected with insulation stay cord on described gib head.

Further, described gib head consists of straight-run of pipe and the coupler body that is fixed on straight tube front end, and the endoporus of described straight tube is spliced eye.

Further, described coupler body is at least two and be circumferentially uniformly distributed along straight tube.

Further, described shank front end bending forms hook formation, and described straight tube rear end has the groove that width is greater than shank diameter vertically.

Further, described stay cord is by rear to the front straight tube that passes, and the front end of stay cord is equipped with anticreep knot.

Further, the described neck of hook is stretching structure.

Further, described gib head is made by insulating material.

The beneficial effects of the utility model: the auxiliary drag hook of transmission line tree bamboo obstacle cleaning of the present utility model, comprise gib head and the insulation neck of hook, on described gib head, be provided with spliced eye, the setting of described neck of hook front end can be inserted the shank of spliced eye, on described gib head, be connected with insulation stay cord, during use, personnel insert shank in spliced eye outside safe distance, by the neck of hook, drag hook is delivered to and needed felling branch branches and leaves place, by the stay cord branches and leaves that further, cut down, the potential safety hazard of can elimination personnel getting an electric shock, also can prevent that the hit circuit of the branches and leaves that broken apart by chopping or equipment from causing its damage, in addition, coupler body is a plurality of, more be easy to catch on branch, shank bending, while tackling the branch of easy hook, can directly as drag hook, use, neck of hook length can regulate according to actual conditions, easy to use.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is structural representation of the present utility model.

Embodiment

Below with reference to accompanying drawing, the utility model is elaborated, as shown in the figure: the auxiliary drag hook of transmission line tree bamboo obstacle cleaning of the present embodiment, comprise gib head 1 and the insulation neck of hook 2, on described gib head 1, be provided with spliced eye 3, the described neck of hook 2 front end settings can be inserted the shank 4 of spliced eye 3, on described gib head 1, be connected with insulation stay cord 5, during use, personnel insert shank in spliced eye outside safe distance, by the neck of hook, drag hook is delivered to and needed felling branch branches and leaves place, by the stay cord branches and leaves that further, cut down, the potential safety hazard of can elimination personnel getting an electric shock, also can prevent that the hit circuit of the branches and leaves that broken apart by chopping or equipment from causing its damage, stay cord furthers and furthers with respect to the direct use neck of hook, easier folding and unfolding, and easily tie up fixing, needn't with one, hold the neck of hook all the time, be more convenient for cutting down.

As the further improvement of technique scheme, described gib head 1 consists of straight-run of pipe 1a and the coupler body 1b that is fixed on straight tube front end, and the endoporus of described straight tube 1a is spliced eye, simple in structure, needn't process specially spliced eye, and cost of manufacture is low.

As the further improvement of technique scheme, described coupler body 1b is at least two and be circumferentially uniformly distributed along straight tube 1a, and the coupler body of the present embodiment is 3, to the tree bamboo branches and leaves in any orientation of drag hook, all can carry out easily hook.

Further improvement as technique scheme, described shank 4 front end bendings form hook formation, described straight tube 1a rear end has the groove 6 that width is greater than shank 4 diameters vertically, the shank of hook formation can make the neck of hook directly hook some than the branch that is easier to catch on, straight tube fluting makes the shank of hook formation can stretch in hole and to drag hook and support equally.

As the further improvement of technique scheme, described stay cord 5 is by rear extremely front through straight tube 1a, and the front end of stay cord 5 is equipped with anticreep knot 7, makes stay cord along the axial tractive of straight tube, prevent that drag hook from breaking off relations.
