Description
Technical field
The utility model relates to a kind of two-way self-traction wire high-altitude hotline maintenance car be positioned on transmission line, is applied to electric power overhaul.
Background technology
Run in transmission line wire long term exposure lowered in field environment, often can damage, the situation such as disconnected stock, in time wire is repaired with regard to needs for avoiding line-outage contingency.And the stockbridge damper be arranged on wire is also often because install loosely, the reasons such as wire vibrations and slippage are to conducting wire sag point central authorities, artificial outlet is needed to be resetted, current operating personnel carries out having a power failure or live-line maintenance operation on transmission line wire, the power tool used is rope ladder head or outlet driving, these two kinds of devices are all easy metallic supports, mechanical drive unit, just can must return by cable traction on operating personnel's pedal or shaft tower after remote outlet, operating personnel's physical demands is large, because simple rack there is no personnel activity and tool storage space, physical demands on wire and support must be climbed large when operating personnel operates on wire, the physical demands of the frightened operating personnel when higher position operates large-span conductors over the ground due to high-altitude can be multiplied again, especially in the operations such as the preformed conducting wire repair strip of installation, operating personnel also needs to carry the aluminium horizontal ladder reaching 3 meters and to ride driving outlet operation, then difficulty is larger.
What transmission line wire construction both at home and abroad or maintenance used at present goes out the Line tool, and be broadly divided into three types, the first goes out the Line tool for sliding class, mainly comprise rope ladder head, glding type driving etc., its structure is as shown below, and main feature is, structure is simply configured to propping up primarily of pulley; Lightweight deadweight is generally convenient for carrying at below 5kg; Without any actuating unit, the main staff tractive wire that leans on realizes sliding.
Slide class and go out the Line tool, because of needs operating personnel voluntarily tractive slide on wire, operating personnel's physical demands is very large, the short distance outlet that wire gradient is less can only be used for, time simultaneously owing to sliding, operating personnel's crank personnel riding comfort is very poor, and instrument is placed nowhere and can only be carried with kit and place the basic tool such as pliers, spanner, carries out stockbridge damper reset, wire is wound around the simple projects such as process.
The second goes out the Line tool for class of riding, and mainly contains single conductor driving, two-conductor line driving, four line drivings etc.This type of driving is generally made up of body part, running part and undercarriage, brake part.Body part wherein comprises vehicle frame, seat; Running part comprises pedal, gear, chain or power transmission shaft; Undercarriage comprises driving wheel, driven pulley.Driving wheel wherein and driven pulley are all positioned at (comprising sub-conductor driven pulley) top at seat, first the driving wheel of driving and driven pulley are suspended on wire during use, operating personnel is sitting on the seat of car body, can ride along wire by stepping on pedal, total weight is generally at about 20-40kg.
Class of riding goes out the Line tool, owing to having installed transmission mechanism, driving wheel can be driven to ride along wire by pedal, operating personnel can be sitting on vehicle seat rightly, comfortableness increases, longer-distance outlet operation can be carried out, but due to needs manpower ride operating personnel need after completing inspection operation task, ride go back to shaft tower position, difficult physical demands of riding when wire gradient is larger is larger.Its simple and easy vehicle frame equally cannot storing tools, and can only carry with a kit and place the basic tool such as pliers, spanner, the events in operation that can carry out are also limited.
The third goes out the Line tool for Mechanical Driven class, there is Japan in the main place of production at present, Germany etc., generally be made up of cage car body and driving device, although it is higher that this type of goes out the Line tool passenger comfortableness, more instrument and material can be deposited, but the general overall weight of complex structure all reaches more than 100kg, be not suitable for the transport in especially mountain area, field, upper air installing difficulty is also larger simultaneously, use and understand to the larger centralized load of wire increase, inapplicablely twoly with below 220kV to divide and the circuit of single conductor, be usually used in the annexes such as 500kV Above Transmission Lines quadripartion above lead spacer and occasion is installed.
Our province belongs to hills landforms 220kV and often needs to cross over mountain valley, river with line, line span is general all larger, at present, the following transmission line of our province 220kV goes out wire operation, still the comparatively easy instrument of many uses first, second kind above-mentioned, the physical demands of personnel is large, comfortableness is poor, when using aerophobia sense comparatively strong, again because using the instruments such as the rope ladder head of simple rack structure or outlet driving, cannot carry more tool materials, job area is also limited.
