Description

Strain insulator wire stockbridge damper instrument is changed in portable power failure

Technical field

The utility model relates to a kind of replacing instrument, relates to or rather a kind of instrument of changing strain insulator wire stockbridge damper.

Background technology

The overhead transmission line conductor stockbridge damper, due to the impact of the meteorological conditions such as wind-engaging, rain, ice throughout the year, easily causes stockbridge damper corrosion distortion or tup fracture, affects its shockproof properties.Old transmission line particularly, the operation time limit is long, and wire stockbridge damper corrupted has ascendant trend year by year, makes replacing, the service work of conducting wire stockbridge damper day by day frequent.

In the replacing strain insulator wire stockbridge damper operation that has a power failure, while particularly changing strain insulator list string wire stockbridge damper, because strain insulator is that level is installed, the wire stockbridge damper is distant apart from the positional distance of cross-arm, and routine replacement, the traditional way of installation strain insulator wire stockbridge damper mainly contain parallel terraced method, rope ladder method, rope method.Parallel terraced method is that the operating personnel is by being fixed on parallel ladder on cross-arm and wire, step on to wire stockbridge damper to be replaced position and changed, the method needs at least three ground support staff to be responsible for transmitting parallel ladder, on two shaft towers, the operating personnel coordinates responsible install, remove parallel ladder and replacing stockbridge damper, whole operation procedure is very loaded down with trivial details, have a big risk, waste time and energy, inefficiency.The rope ladder method is hung rope ladder on wire, and the operating personnel is changed by stepping on rope ladder to wire stockbridge damper to be replaced position, and the method drawback is that operation labor intensity is large, and coefficient of safety is low, and the used time is longer, and needs four ground support staff.The rope method is to utilize cable loop to lean around nearly side of wire was first insulator place, wire is connected with cross-arm, the operating personnel enters stockbridge damper to be replaced place by rope and is changed stockbridge damper, and there is the drawback that operation labor intensity is large, the used time is long, coefficient of safety is low equally in the method.In general, above three kinds of operational methods all exist have a big risk, program is loaded down with trivial details, it is large to consume one's strength, long, ineffective problem of used time.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art provides a kind of portable power failure to change strain insulator wire stockbridge damper instrument, easy to carry, easy and simple to handle, stability is better, reduces the field operation risk, time saving and energy saving, reduce as far as possible the operating personnel and save the labour, increase work efficiency.

Of the present utility model being characterised in that: comprise main insulation pipe, side of wire was Universal hook, cross-arm side Universal hook, U-shaped connecting plate, punching set bolt, 4-6 minor insulation pipe is set on described main insulation pipe, two ends at the main insulation pipe connect the U-shaped connecting plate by the punching set bolt, before the nut of described punching set bolt both sides, install spring shim additional; The U-shaped connecting plate of one end connects the side of wire was Universal hook by nut, spring shim, and side of wire was Universal hook lower end arranges side of wire was safety wire connecting plate; Cross-arm side safety wire connecting hole, support bar connecting plate are set on the U-shaped connecting plate of the other end, and the support bar connecting plate connects support bar, and support bar is connected and fixed clamping plate, and this U-shaped connecting plate connects the cross-arm side Universal hook by connecting rod, direction regulator; Connect the safety wire through the main insulation pipe between described side of wire was safety wire connecting plate, cross-arm side safety wire connecting hole.

Described support bar connecting plate is two .

The know-why that the utility model adopts: utilize lever principle and leg-of-mutton stability, after the operating personnel hangs up properly centipede type ladder cross-arm side Universal hook, by single underfooting, press a side of centipede type ladder like a cork side of wire was to be hung on wire, the fixed mount that the staff can regulate simultaneously is (by support bar, strap forms) securely centipede type ladder is fixed on cross-arm master material, the staff just can enter the setting of wire stockbridge damper to be replaced in safety and steady ground by centipede type ladder like this, changed like a cork or installed strain insulator wire stockbridge damper, particularly change the work of single string strain insulator wire stockbridge damper and especially embody its superiority.

The utility model adopts main insulation pipe, minor insulation pipe to make centipede type ladder: insulated tube self intensity is high, light, after being transformed into the climbing tool centipede type ladder, be easy to carry, convenient transportation, reduce labour intensity, in tube wall, individual safety wire can be installed easily simultaneously, make the operating personnel not need to install again individual safety wire, reduce work flow, easy and simple to handle, reduced operating risk.

The utility model adopts side of wire was, cross-arm side Universal hook: according to the universal characteristic of side of wire was, cross-arm side Universal hook, when conducting wire side and cross-arm side Universal hook, the operating personnel can according to the residing position of wire, angle and cross-arm master material towards difference freely select, easily Universal hook effectively is connected with wire, cross-arm, operates also more convenient.

The utility model employing spring shim and punching set bolt fixing cord side, cross-arm side Universal hook: the spring shim self-characteristic has determined that it in use can produce elasticity tension.Punching set bolt fixing cord side, cross-arm side Universal hook are on insulated tube the time, before installing nut, the bolt both sides install spring shim additional, the elasticity tension that spring shim produces can make the not any direction swing after being fixed on insulated tube of side of wire was, cross-arm side Universal hook, also be convenient to the direction that the operating personnel regulates side of wire was, cross-arm side Universal hook simultaneously, simple to operate, flexible, convenient.

The utility model adopts the cross-arm side Universal hook: for cross arm of tower master material towards difference, the operating personnel can regulate the direction of cross-arm side Universal hook easily, the cross-arm side Universal hook is hung over securely on the cross-arm master material of any direction, more laborsaving during operating personnel's operation, operate also easier.

The utility model is set up Adjustable bracing bar and be take and strengthen stability: centipede type ladder, the cross-arm side Universal hook as the reinforced insulation pipe, made are fixed on the stability on cross-arm, setting up an Adjustable bracing bar is fixed, make cross arm of tower master material, the cross-arm side Universal hook hung up properly and Adjustable bracing bar form triangular structure, effectively prevented that centipede type ladder from swinging.In addition, Adjustable bracing bar by the self-regulation direction can be fixed on different towards cross arm of tower master material on, strengthen the stability of centipede type ladder, make the operating personnel to enter working point by the centipede type ladder safety and steady and carry out operation, reduced operating risk.

As shown from the above technical solution, the utility model is used safety, lightweight, be convenient to transport, carry, install, good stability, used dexterity, simple operation, safe and reliable, reduce operating personnel's labour intensity and operating risk in operation process, improved operating efficiency, reduced the line outage time, save maintenance construction operation expense, can also change for having a power failure strain rod tower self-destruction insulator and drainage thread.
