Description

500kV transmission line overhead ground wire driving

Technical field

The utility model relates to the ultra-high-tension power transmission line repair apparatus, specifically is a kind of being used on 500kV transmission line overhead ground wire overhead ground wire or optical cable to be implemented the preformed 500kV transmission line overhead ground wire driving of studying for a second time courses one has flunked.

Background technology

Work on the present domestic 500kV transmission line overhead ground wire, generally use the alloy aluminum driving of specification, be mainly used in disappearing by scarce (as disconnected strand of ground wire or optical cable) and installation lightning protection device (as anti-shock arrester) and be installed in work such as line detector on the overhead ground wire as 120cm * 42cm and 138cm * 42cm.

Along with the continuous development of power grid construction, the special operation on the overhead ground wire is frequent gradually, therefore some problems occurred when using driving, mainly shows the following aspects:

A practicality aspect

When 1, on 500kV transmission line overhead ground wire or optical cable, studying for a second time courses one has flunked bar and study for a second time courses one has flunked with preformed armor rods, require the driving electrician at first need to be studied for a second time courses one has flunked the optical cable surface recovery original state of part, and surperficial burr polished smooth, next preformed armor rods is studied for a second time courses one has flunked bar and should be contacted with optical cable closely, its blue line center should be positioned at the most serious place of damage, twine to both sides, winding direction should be consistent and closely even with ground wire (optical cable) strand system direction, and burst place of will breaking all covers.And preformed armor rods length is 1.5~1.7 meters, driving length is 0.42 meter, FROM when the operating personnel sits driving and carries out preformed studying for a second time courses one has flunked is about 1 meter, and can not guarantee that preformed armor rods studies for a second time courses one has flunked bar and should closely contact with ground wire (optical cable), preformed armor rods can only be cast aside curved, cause the preformed armor rods distortion, cause winding inhomogeneous gapped.

2, " 8.3.8.3 " bar requires in " State Grid Corporation of China's electric power safety working regulation ": " after the hanging ladder load, should keep ground wire and the human body must not be less than 3.9 meters to the safe distance of below live wire." general overhead ground wire (optical cable) is 8~13 meters with the live wire distance, after the actual hanging ladder load, ground wire sag minimum point approximately descends 2 meters, adds that the influence of tractive force that is subjected to the ground staff to draw driving to slide with pull rope descends 0.5 meter and driving itself highly again.By above analysis, calculating, at this moment ground wire and human body are approximately 4.12 meters to the minimum range of below live wire.Therefore when transmitting preformed armor rods (length is 1.5~1.7 meters), ground wire and human body are approximately 2.42~2.62 meters to the minimum range of below live wire, do not meet " safety " requirement.

The B design aspect

1,500kV transmission line major part is between location, hills and the high mountain high hill, average span is about 400 meters, pull out on the ubiquity or press down, and driving does not stop brake apparatus, so on this section, slide or during operation, the driving electrician can only go up at overhead ground wire (optical cable) with the safety belt fence twines several circles, in case sport car, but coasting distance is when longer, can the heavy wear fence, and the resistance that sliding speed is subjected to is bigger, causes ground traction driving personnel labor intensity to increase.

2, " 6.2.5 " bar requires in " State Grid Corporation of China's electric power safety working regulation ": " when the shaft tower work high above the ground, should use the dual fail-safe safety belt of back rope." go up operation at ground wire (optical cable), inconvenient because of using the back rope, adopt two fences of safety belt to carry out two protections, behind the arrival setting, sport car when preventing operation can only be untied a rhizosphere hurdle and twine several circles, has violated " safety " requirement.

C manufacturing process aspect

Two of driving walk movable pulley and adopt male connection, when therefore sliding, pulley respectively with alloy aluminum pipe and overhead ground wire friction, forms bigger resistance, the long-time or use meeting of growing distance is to the serious wear of pulley own; It is to be undertaken by working in coordination of ground electrician's dragline messenger that next driving electrician slides on ground wire (optical cable), and the far away and weather conditions at setting increase labour intensity and increase the activity duration for driving electrician and ground traction electrician.

Summary of the invention

The utility model is implemented to be difficult for, can not to carry problems such as the preformed armor rods and the driving length restriction operating personnel scope of repair with car in order to solve the anti-sport car of existing overhead ground wire driving, and a kind of 500kV transmission line overhead ground wire driving is provided.

The utility model is to adopt following technical scheme to realize: 500kV transmission line overhead ground wire driving, comprise vehicle frame, vehicle frame is provided with the pulley mechanism of realizing that vehicle frame slides along overhead ground wire, pulley mechanism comprises with the fixing fixed axis of vehicle frame and is placed on pulley on the fixed axis, the long 1.6-1.8 rice of vehicle frame, vehicle frame is provided with the preformed armor rods carrying case of 1.5-1.7 rice.

The utility model is a 1.6-1.8 rice with the Design of length of driving vehicle frame, has strengthened driving electrician's maintenance practical range, is convenient to the driving electrician and studies for a second time courses one has flunked bar with preformed armor rods ground wire (optical cable) is studied for a second time courses one has flunked, and can guarantee technological requirement; And set up the preformed armor rods carrying case and place preformed armor rods and study for a second time courses one has flunked bar, solved the driving electrician carry preformed armor rods inconvenient and when transmitting preformed armor rods with electrified body apart from not enough problem.

In addition, have additional bearing (being that pulley is fixed by bearing and fixed axis) between pulley mechanism middle pulley and fixed axis, and dispose brake gear on the vehicle frame.Described brake gear can adopt existing known products.Bearing the resistance that has reduced when driving slides is set, alleviated ground traction driving personnel's labour intensity, can alleviate wearing and tearing simultaneously to overhead ground wire (optical cable) and pulley itself; Because the setting of brake gear when the driving electrician goes up operation at overhead ground wire (optical cable), can freely be controlled driving and only stop, and provides guarantee to inherently safe, pulls out or presses down even meet, and still can effectively avoid sport car hidden danger.

The utility model is simple and reasonable for structure, and driving length satisfies the operating personnel and overhauls needs, can carry preformed armor rods with car, and anti-sport car is effective, and the convenient working personnel implement preformed studying for a second time courses one has flunked to overhead ground wire or optical cable on 500kV transmission line overhead ground wire.
