Abstract

The utility model relates to a three-jaw blunt end inner-hook protection rope special for ensuring the safety of a power transmission line. The three-jaw blunt end inner-hook protection rope comprises a main rope and three-jaw blunt end inner hooks, and is characterized in that the three-jaw blunt end inner hooks are fixedly arranged on the main rope at uniform intervals; knots are tied on the main rope at the upper and lower ends of the three-jaw blunt end inner hooks; the three-jaw blunt end inner hooks are positioned on the main rope among the knots. According to the three-jaw blunt end inner-hook protection rope, the three-jaw blunt inner hooks are fixedly arranged on the main rope at uniform intervals, and the three-jaw inner hooks can be used for hanging and connecting a safe rope conveniently and rapidly; the three-jaw blunt end inner-hook protection rope is simple in structure, and is scientific in design. In the protection rope, the three-jaw blunt end inner hooks are arranged on the main rope at uniform intervals, so that the problem of ''blind spots'' caused by no protection of a safety rope during climbing of a tower is solved, and the safety performance of a tower climber is improved.

Description

The blunt nosed interior hook protection rope of transmission line of electricity secure private three-jaw
Technical field
The utility model belongs to power domain, relates to the operation protection of transmission line of electricity, the blunt nosed interior hook protection rope of especially a kind of transmission line of electricity secure private three-jaw.
Background technology
Transmission of electricity high-tension electricity circuit sets up in group tower, and in order to guarantee operating personnel's safety, applying at present more is to adopt safety rope to implement protection.Safety rope is in climbing tower, assembling process, and because the tower of angle bar assembling becomes cutting state, upwards climbing tower is very fast and on tower during operation, and safety rope there will be the problem of discontinuous protection; Although can carry out self-locking by self-locking device, cause the increase of climbing tower weight of equipment, use inconvenient.
Utility model content
The purpose of this utility model is to overcome the weak point of original technology, provides a kind of scientific structure design, the blunt nosed interior hook protection of transmission line of electricity secure private three-jaw esy to use, safe and reliable to restrict.
The technical scheme that the utility model technical solution problem adopts is:
The blunt nosed interior hook protection rope of a kind of transmission line of electricity secure private three-jaw; comprise the blunt nosed interior hook of main rope and three-jaw; it is characterized in that: on main rope, uniform interval is fixed with the blunt nosed interior hook of three-jaw; on the main rope of the blunt nosed interior hook upper and lower end of three-jaw, be all equipped with tieing, the blunt nosed interior hook of three-jaw is positioned on the main rope between tieing.
And the gib head of the blunt nosed interior hook of described three-jaw for to hook in the obtuse angle at axis position.
Advantage of the present utility model and good effect are:
1, this protection rope uniform interval on main rope is fixed with the blunt nosed interior hook of three-jaw, and in this three-jaw, hook can articulate safety rope easily and quickly, simple in structure, design science.
2, the three-jaw of this protection rope is hooked in uniform interval on main rope in blunt nosed and arranges, and avoids climbing tower to occur, without " blind spot " problem of safety rope protection, having improved climbing tower personnel's security performance.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the local enlarged diagram (broken section) of Fig. 1.
The specific embodiment:
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.
The blunt nosed interior hook protection rope of a kind of transmission line of electricity secure private three-jaw, on main rope 3, uniform interval is fixed with the blunt nosed interior hook 1 of three-jaw.The gib head of the blunt nosed interior hook of described three-jaw for to hook in the obtuse angle at axis position, so that the safety rope entering in gib head can not be taken off; The fixed form of the blunt nosed interior hook of described three-jaw and main rope is to adopt on main rope, to be shaped with the mode of tieing 2, on the main rope of the blunt nosed interior hook upper and lower end of three-jaw, is all equipped with tieing, and the blunt nosed interior hook of three-jaw is positioned on the main rope between tieing.

Claims (2)
