Abstract

The utility model relates to Maintenance of Electric Transmission Line instrument, and specifically the special shank of a kind of electric power maintenance, comprises gib head and insulating bar, and described gib head comprises hook and the neck of hook; Described hook comprises the bend of circular arc and linear hook handle, and the radius of curvature of same bend is identical, and hook is fixedly connected with the neck of hook by hook handle; One end of the described neck of hook is fixedly connected with one end of insulating bar; The quantity of described hook is two to four, and the radius of curvature of the bend of any two hooks is different.The beneficial effect of the technical program is: shank is arranged the hook that two to four sizes are different, and can adapt to the branch of different size, hook is dragged effective, easy to use.

Description

The special shank of a kind of electric power maintenance
Technical field
The utility model relates to Maintenance of Electric Transmission Line instrument, specifically the special shank of a kind of electric power maintenance.
Background technology
Branch near transmission line and power equipment facility is easy to cause equipment short circuit, also may break electric wire, damage equipment, cause power failure, therefore, the branch cleared up near transmission line and power equipment facility is the important content of Maintenance of Electric Transmission Line work in time.Owing to needing the branch pruned generally all in higher position, so Maintenance of Electric Transmission Line personnel adopt insulation shank by branch hook to home, then to its pruning.But branch thickness differs, if hook dimensions is excessive or too small, can affect the effect that branch dragged by hook, interim hook of changing then can affect operating efficiency.
Documents (Authorization Notice No.: the CN203398645U applying date: on July 30th, 2013) discloses a kind of transmission line tree bamboo obstacle cleaning and assists drag hook, and comprise gib head and the insulation neck of hook, its coupler body is at least two.The technical problem that this technical scheme solves is " all can easily hook to the tree bamboo branches and leaves in any orientation of drag hook ", does not do requirement, therefore can not solve the technical problem that different size branch dragged by hook to the size of coupler body.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easy to use, can adapt to the special shank of electric power maintenance of different size branch.
Technical problem to be solved in the utility model realizes by the following technical solutions.
The special shank of a kind of electric power maintenance, comprise gib head and insulating bar, described gib head comprises hook and the neck of hook; Described hook comprises the bend of circular arc and linear hook handle, and the radius of curvature of same bend is identical, and hook is fixedly connected with the neck of hook by hook handle; One end of the described neck of hook is fixedly connected with one end of insulating bar; The quantity of described hook is two to four, and the radius of curvature of the bend of any two hooks is different.The beneficial effect of the technical program is: shank is arranged the hook that two to four sizes are different, and can adapt to the branch of different size, hook is dragged effective, easy to use.
As preferably, the quantity of described hook is four.Adopt the technical program, the hook that uniform four sizes are different on the neck of hook, can adapt to the branch of four kinds of different sizes.
As preferably, one end of the described neck of hook and one end of insulating bar are respectively equipped with screwed hole and the external screw thread of cooperation, and the neck of hook is connected with insulating bar threaded engagement.With being threaded gib head and insulating bar being linked together, being not only connected firmly, and convenient disassembly, be conducive to replacing or the maintenance of gib head or insulating bar.
As preferably, also comprise lengthened insulative bar, one end of lengthened insulative bar is provided with screwed hole, and insulating bar is provided with relative to the other end connecting the neck of hook one end external screw thread coordinated with the screwed hole on lengthened insulative bar, and insulating bar is connected with lengthened insulative bar threaded engagement.If branch excessive height, just need to use the longer shank of length to carry out hook to it and drag, but long shank is not easy to make and carry.Adopt the technical program, solve the technical problem that long shank is not easy to make and carry.
As preferably, the described neck of hook is provided with stay cord ring.Before using, one end of insulation stay cord is tied up on stay cord ring, use shank that branch is pulled to home, vacant for insulation stay cord one end is tied up on the fixed object such as trunk or railing, can prune branch.Adopt the technical program, in pruning process, hold shank without the need for special messenger, improve operating efficiency.
As preferably, described stay cord ring is metal material.The stay cord ring good toughness that metal material makes, intensity is high, long service life.
As preferably, described stay cord boxing is connected on the neck of hook.Compared to stay cord ring being riveted or using other modes to be fixed on the neck of hook, weld more simple, fixation.
As preferably, described hook and the neck of hook are metal material and make, and hook is being welded on the neck of hook.Because metal material generally has good toughness and intensity, use metal material make hook and the neck of hook and weld together, not only cost is low, and manufacture craft is simple, and gib head intensity is high, long service life.
