Description

Safety device for power line tower
Technical Field
The utility model relates to a safety device for a power line tower.
Background
A line tower life rope commonly used for an electric power line uses a self-locking guiding type falling protector. When the maintainer climbs the upper and lower ladder stands, the portable shuttle climbs upwards along the rigid guide rail safety system. Once a fall occurs, the shuttle locks onto the rigid rail to control the descent. Only at the climbing in-process, the maintainer need be hand the slow upper and lower cat ladder of safe shuttle, and the safety hook in case the landing downwards will be deadlocked, and this brings a large amount of physical demands for the maintainer, goes on the shaft tower that 30 meters is high back physical demands for a large part, brings the risk for the maintainer's safety, and this kind of safety arrangement uses and wastes time and energy, and this kind of safety arrangement expense is higher simultaneously, can not universal use.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides a safety device for a power line tower, which is simple in structure, convenient to manufacture, safe and reliable, can ensure the safety of line maintainers in getting on and off the tower and in maintenance construction, and plays a role in protecting the life safety of the line maintainers.
The technical scheme of the utility model for solving the technical problems is as follows: the utility model provides a be used for electric power line tower safety device, is including safety rope and the fixed cross arm of a plurality of safety rope, a plurality of the fixed cross arm of safety rope equidistance respectively installs on the cat ladder of electric power line tower, the fixed cross arm of safety rope includes staple bolt, dead lever and is used for the wire rope card of fixed safety rope, the dead lever is fixed on the cat ladder, the staple bolt is fixed dead lever one end, the wire rope card is fixed the dead lever other end, safety rope one end is fixed on electric power line tower top, and the other end passes in proper order in the wire rope card of from the top down fixing on the dead lever.
The utility model further defines the technical scheme as follows:
preferably, the safety rope is a steel wire rope.
Preferably, the length of the life rope of the safety rope is the same as the distance between the ladder stand with the highest position and the ladder stand with the lowest position of the power line tower, and the condition that the maintenance personnel do not have a ladder stand and are protected by the safety life rope is guaranteed.
Preferably, the following components: the length of the safety rope is 25-35m, and the sectional area of the safety rope is 10-12 square millimeters, so that the life rope can have enough bearing capacity.
Preferably, two adjacent safety life fixed cross arms are 5m apart from each other, prevent that the maintainer from climbing the in-process and falling and play the cushioning effect.
The utility model has the beneficial effects that: the safety protection device is simple in structure, easy and convenient to mount and dismount the tower, and the maintainers do not need to difficultly lift the safety belt rope lock to climb slowly, so that the physical consumption of the maintainers for mounting and dismounting the tower is low, time and labor are saved, the safety of the maintainers is guaranteed, and meanwhile, the safety protection device is low in cost, simple in structure, convenient to manufacture, safe and reliable, and plays a role in protecting the life safety of the line maintainers.

Detailed Description
Example 1
The embodiment provides a safety device for a power line tower, which is structurally shown in fig. 1-2 and comprises a safety rope 1 and a plurality of safety rope fixing cross arms 2, wherein the safety rope is a steel wire rope, the length of the life rope is the same as the distance between the ladder 4 at the highest position and the ladder at the lowest position of the power line tower 3 and is 30m, the sectional area is 10 square millimeters, and a plurality of safety rope fixed cross arms are installed on the cat ladder of power line tower respectively equidistance, and the distance between two adjacent safety rope fixed cross arms is 5m, and safety rope fixed cross arm includes staple bolt 5, dead lever 6 and is used for fixing safety rope's wire rope card 7, and the dead lever is fixed on the cat ladder, and the staple bolt is fixed dead lever one end, the wire rope card is fixed at the dead lever other end, and safety rope one end is fixed on power line tower top, and the other end passes in proper order in the wire rope card of fixing on the dead lever from the top down.
The embodiment is used for installing a safety device of a power line tower, and the specific steps include the following:
step one, manufacturing a life rope fixing cross arm support 6 group in advance, and preparing 1 steel wire rope with the length of 30 meters and the section of 10 square millimeters;
step two, preparing 6 safety rope fixing cross arms for each tower, and installing the safety rope fixing cross arms from 2.0 meters away from the ground on the basis of the electric power line tower ladder stands, wherein one safety rope fixing cross arm is installed at intervals of 5 m;
step three, installing the safety rope in a steel wire rope clamp on the life rope fixing cross arm, and using a steel wire rope with the section of 10 square millimeters as the life rope to ensure that the life rope has enough bearing capacity;
and step four, using a common double-buckle safety belt to go up and down the tower, fixing and buckling the safety belt lock catch at the upper end of the fixing clip when the safety rope is used for fixing the clip in a transition mode, and then detaching the safety belt lock catch at the lower end of the fixing clip, so that the safety belt lock catch is operated alternately, and the safety belt lock catch is prevented from being tripped in the process of climbing by a maintainer up and down to cause safety accidents.
In addition to the above embodiments, the present invention may have other embodiments, and any technical solutions formed by equivalent substitutions or equivalent transformations are within the scope of the present invention.
