Abstract
The present invention relates to a kind of transmission line of electricity group tower activity safety net, stand in the outside group of steel tower and have tower material of iron tower, main rope is fixed with between tower material of iron tower, it is characterized in that: on main rope, uniform interval is fixed with the blunt nosed interior hook of three-jaw, the gib head of the blunt nosed interior hook of this three-jaw is hook in the obtuse angle at axis position, the blunt nosed interior hook of the three-jaw between main rope adopts link mode longitudinally or transversely connect other main ropes again and form a closed activity safety net thus.Intrinsic safety the whole network can realize the safety of staff when horizontal operation and vertical climbing tower, when horizontal operation, can add one safety rope again, jointly use with the safe hanging point of steelframe on the blunt nosed interior hook of three-jaw; When climbing tower, when climbing tower staff accidentally drop fall time, in the vertical direction is hooked staff by the blunt nosed interior hook of three-jaw, prevent tower from falling, meanwhile, the blunt nosed interior hook of three-jaw can prevent staff of stabbing, and can also reduce resistance in safety rope uphill process, intrinsic safety the whole network can also be taken off fast after fulfiling assignment, and reuses.
Description
Technical field
The invention belongs to power domain, relate to the operation protection of transmission line of electricity, especially a kind of transmission line of electricity group tower activity safety net.
Background technology
In transmission of electricity high-tension electricity construction of line group tower, in order to ensure the safety of staff, what application was more at present is 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 self-locking can be carried out by self-locking device, cause the increase of climbing tower weight of equipment, use inconvenience.
In addition, carry out, in climbing tower, the process of walking on tower, depending merely on the safety that a safety rope cannot ensure staff staff, careless slightlyly just easily to cause casualties.Therefore, existing safety rope mode is the safety work that cannot realize staff.
Summary of the invention
The object of the invention is to the weak point overcoming original technology, a kind of scientific structure design, transmission line of electricity group tower activity safety net esy to use, safe and reliable are provided.
The technical scheme that technical solution problem of the present invention adopts is:
A kind of transmission line of electricity group tower activity safety net, stand in the outside group of steel tower and have tower material of iron tower, main rope is fixed with between tower material of iron tower, it is characterized in that: on main rope, uniform interval is fixed with the blunt nosed interior hook of three-jaw, the gib head of the blunt nosed interior hook of this three-jaw is hook in the obtuse angle at axis position, the blunt nosed interior hook of the three-jaw between main rope adopts link mode longitudinally or transversely connect other main ropes again and form a closed activity safety net thus.
And, the fixed form of the blunt nosed interior hook of described three-jaw and main rope adopts the mode being shaped with tieing on main rope, namely on the main rope of the blunt nosed interior hook upper and lower end of three-jaw, all tieing is equipped with, the blunt nosed interior hook of three-jaw is positioned on the main rope between tieing, or adopt fixed cover and main rope be directly fixedly mounted with mode.
Advantage of the present invention and good effect are:
1, intrinsic safety the whole network is that on main rope between steelframe, uniform interval is fixed with the blunt nosed interior hook of three-jaw, safety rope is installed by adjacent main rope, can form the netted layout of safety between steelframe thus, effectively ensure that the personal safety of staff.
2, intrinsic safety the whole network can realize the safety of staff when horizontal operation and vertical climbing tower, when horizontal operation, can add one safety rope again, jointly use with the safe hanging point of steelframe on the blunt nosed interior hook of three-jaw; When climbing tower, when climbing tower staff accidentally drop fall time, in the vertical direction is hooked staff by the blunt nosed interior hook of three-jaw, prevent tower from falling, meanwhile, the blunt nosed interior hook of three-jaw can prevent staff of stabbing, and can also reduce resistance in safety rope uphill process, intrinsic safety the whole network can also be taken off fast after fulfiling assignment, and reuses.
3, in the three-jaw that uses of intrinsic safety the whole network, hook can safety rope easily and quickly, and structure is simple, design science.Be hooked in uniform interval on main rope in the three-jaw of protection rope is blunt nosed to arrange, avoid climbing tower to occur " blind spot " problem protected without safety rope, improve the security performance of climbing tower personnel.
Accompanying drawing explanation
Fig. 1 is using state structural representation of the present invention;
Fig. 2 is the structural representation of the blunt nosed interior hook protection rope of three-jaw of the present invention;
Fig. 3 is blunt nosed interior hook protection rope structure enlarged diagram (broken section) of the three-jaw of Fig. 1.
Detailed description of the invention:
For content of the present invention, Characteristic can be understood further, 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 protection scope of the present invention thus.
A kind of transmission line of electricity group tower activity safety net, stand in the outside group of steel tower 1 and have tower material of iron tower 4, between tower material of iron tower, be fixed with main rope 3, steel tower is provided with lateral conductor 2, keeps the erectility of steel tower thus.
Innovative point of the present invention is:
1, on main rope, uniform interval is fixed with the blunt nosed interior hook 5 of three-jaw, and the gib head of the blunt nosed interior hook of this three-jaw is hook in the obtuse angle at axis position, can not take off to make the safety rope entered in gib head.The fixed form of the blunt nosed interior hook of three-jaw and main rope adopts the mode being shaped with tieing 6 on main rope, namely on the main rope of the blunt nosed interior hook upper and lower end of three-jaw, is all equipped with tieing, makes the blunt nosed interior hook of three-jaw be positioned on the main rope between tieing; What also can adopt fixed cover and main rope is directly fixedly mounted with mode.
2, the blunt nosed interior hook of the three-jaw between main rope can also adopt link mode to connect main rope (safety rope) again, in longitudinal direction or transversely can mount, the activity safety net that formation one is closed thus.
3, the blunt nosed interior hook of three-jaw can adopt carbon fiber to make, with guaranteed strength.
Claims (2)
