Description

Permanent anti-theft type high-voltage transmission line towers protection device

Technical field: the utility model relates to a kind of high-voltage transmission line towers protection device.

Background technology: as far back as the initial stage eighties, external building trade has just been taked the generation of otherwise effective technique measure control high-altitude falling accident, to the end of the eighties, the power construction enterprise of countries such as Japan, Germany has developed a series of extra high voltage network and has climbed falling proof device, as speed difference self-locking device, horizontal self-locking device, vertical mobile falling proof device etc., but cost is all relatively very high, and generally can not use for a long time, does not also have antitheft performance.Be not suitable in operation of power networks is safeguarded, using.

Speed difference automatic controller is to use the most extensively at present in the world, also is one of advanced anti-fall utensil in high-altitude.The acceleration that speed difference automatic controller produces when utilizing the object tenesmus has prevented the operator in high-altitude to fall accidentally in moment.The tenesmus distance is no more than 200mm, has promptly protected operator's life effectively, has avoided drop person to be subjected to the injury of strong impact force again.Simultaneously, significantly reduced the possibility of colliding other object and damaging.And when the operator was equipped with this utensil and moves as upper and lower, left and right with operate as normal speed, the cable wire in the utensil was also freely stretching flexibly.In case the operator falls accidentally, this utensil promptly produces above-mentioned effect.Speed difference automatic controller housing is selected high-strength aluminum alloy usually for use, light weight, firm, not aging; The aviation cable wire is a lifting rope, intensity height, wear-resistant, high temperature resistant, corrosion-resistant.All other material all meets international requirement.But speed difference automatic controller is owing to the characteristics of himself have also determined and can't promote the use of in the operation and maintenance work of transmission line of electricity: speed difference automatic controller need be suspended on it on firm thing of top root face when using, and cable wire is hooked in the semicircular ring of lap belt.That is to say that the operating personnel is when stepping on tower; speed difference automatic controller to be carried to iron tower; and also it to be carried to ground during tower down, can only on tower, provide protection in the operation process for the operating personnel, and can not for they at Deng Ta and provide protection in the tower process down.In addition, though speed difference automatic controller has 3 meters～30 meters to wait all size, because its cable wire is to be wrapped in the housing, when carrying, when cable wire surpassed 10m, its deadweight surpassed 5kg, comparatively heavy, and ultra-high-tension power transmission line is general all at 40 to 60m height, obviously can not meet the demands.

The more iron tower protection device that adopts high-strength nylon (or polyamide fibre) rope body during big crossover tower construction both domestic and external, and be used with the self-locking device of various types, its main advantage is that cable body is in light weight, and is easy to loading and unloading.But the corrosion-resistant of high-strength nylon (or polyamide fibre) rope, service life is short, and does not possess anti-theft feature.

For many years, China relies on and Strengthens Safety Management and safety custody, though controlled the high-altitude falling accident that takes place in the transmission line operation to a great extent, distance is fundamentally stopped the generation of this type of accident, guarantee operating personnel's safety from technical measures, also have very big gap.The at present domestic climbing self-locking protecting device that only has the Shanghai Electric Power Co to develop on steel tube tower, to use, but because the structure of himself, determined the defective that himself can't overcome: promptly one is that cable body adopts steel wire rope, easily be corroded, need often to safeguard, can't use on a large scale in the transmission line of electricity in the open air; The 2nd, the iron tower connector is only applicable to steel tube tower, and domestic steel tube tower only in the city, use in the scenic spot morely, and just do not have steel tube tower in the ultra-high-tension power transmission line in the open air, so can't apply on a large scale at all; The 3rd, do not have anti-theft feature, therefore use in the open air, stolen easily, and also when stolen, cable body is upspring, and causes the electrical body ground fault easily; In addition, when falling generation, the tapered end of self-locking device is stung tight cable body by lever principle, damages cable body easily.

Summary of the invention: the technical problem of the required solution of the utility model is: the deficiency that is intended to overcome above-mentioned prior art; a kind of permanent anti-theft type high-voltage transmission line towers protection device is provided; to be implemented in the requirement that extra high voltage network operation maintenance work safety ensures; solve climbing iron tower process exists in 500kV and the following ultra-high-tension power transmission line operation maintenance the high-altitude potential safety hazard of falling, fundamentally prevent the high-altitude to fall casualty accident and the generation of the electrical network ground fault that may cause therefrom.

Its technical scheme is: a kind of permanent anti-theft type high-voltage transmission line towers protection device; comprise strain clamp and steel strand wires; it is characterized in that: the two ends of steel strand wires respectively with an end crimping of two strain clamps; the other end of strain clamp is connected with an end of two U type rings respectively, and the other end of U type ring flexibly connects with the end of two connecting plates respectively.Its technique effect is: the corresponding site place that the connecting plate at this device two is fixed on the section of cranking arm and body of the tower one side of iron tower both sides respectively, when the operation maintenance personnel climb iron tower up and down and carry out upkeep operation on iron towers, utilize this device to cooperate with self-locking device, can prevent effectively and avoid contingent falling accident, guarantee operation maintenance personnel's safety.Compared with prior art, this device has draws materials simply, and cost of manufacture is cheap; Design is simple and clear, installs to be very easy to; In light weight, practical, be adapted at using in the iron tower of various types such as steel tube tower, angle steel tower, cement shaft tower; Long service life, once mounting promptly can forever be used, and can keep general service life with ultra-high-tension power transmission line; And have anti-theft feature, prevent advantages such as stolen.
