Abstract
The utility model relates to the field of high-tension transmission line maintenance technology, specifically relating to a shockproof hammer restorer for an aerial earth wire of high-tension transmission lines. The shockproof hammer on the aerial earth wire of high-tension transmission lines can deviate from the mounting position in operation so that generally workers are required for replacing the shockproof hammer on a ladder hooking on the aerial earth wire. However, the sectional area of the aerial earth wire is small so that hooking a ladder and line-outgoing operation are not allowed, and cutting off the power and grounding the aerial earth wire for maintenance can influence the normal power supply, and moreover, the operation mode can not be used when the aerial earth wire spans the other electric power circuits. The shockproof hammer restorer for an aerial earth wire of high-tension transmission lines comprises fixed plates, impactors and pulleys, wherein two groups of pulleys are arranged between two fixed plates; two fixed plates and the pulleys are fixed by fixed bolts; the impactors are fixed on one end of the fixed plates through the bolts; the impactors and the pulleys are arranged on the upper part of the fixed plates; and control holes are arranged on the bottom of the fixed plates. The shockproof hammer restorer for an aerial earth wire of high-tension transmission lines has the advantages of simple structure and easy and convenient operation, thus avoiding the loss caused by the processing the defects by cutting the power and improving the work efficiency.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line maintenance technology field, specifically a kind of stockbridge damper restorer of ultra-high-tension power transmission line overhead ground wire.
Background technology
On ultra-high-tension power transmission line, all install overhead ground wire, the vibration that causes for fear of gentle breeze generally can be left a certain distance of wire clamp stockbridge damper is installed the damage of overhead ground wire on overhead ground wire.Because influence or bolt looseness that stockbridge damper is in operation and receives natural environment; The installation site can appear departing from stockbridge damper; " positioning " phenomenon that is commonly called as resets as untimely, and stockbridge damper does not just have antihunt action (also can play reaction sometimes; The vibration of aggravation overhead ground wire), threatening the safe operation of electrical network constantly.In regular maintenance, take hanging ladder on overhead ground wire usually at present, by maintainer's manual work the stockbridge damper of " positioning " is resetted and recover; But rules regulation sectional area is less than the overhead ground wire of 50mm2; Do not allow maintainer's hanging ladder outlet work; As take to have a power failure and overhead ground wire landed the stockbridge damper that resets, can influence normal power supply, and if line cross over other power circuit down then can not adopt this operational method.
Summary of the invention
The purpose of the utility model provides a kind of stockbridge damper restorer of ultra-high-tension power transmission line overhead ground wire, and is simple in structure, easy to use, need not have a power failure to carry out the stockbridge damper reset operation.
The technical scheme of the utility model is: be made up of fixed head, impactor, pulley, two groups of pulleys are between two fixed heads, and set bolt is fixed two fixed heads and pulley; Fixed head one end has impactor through bolt; Impactor and pulley are positioned at fixed head top, and the fixed head bottom is provided with control hole.
The utility model has the advantages that: simple in structure, easy and simple to handle, solved under the condition that does not have a power failure, to the difficult problem that different model overhead ground wire stockbridge damper resets, having avoided has a power failure handles the loss that this type of defective causes, and has improved operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Among the figure: 1 impactor, 2 set bolts, 3 pulleys, 4 fixed heads, 5 control holes.
Can know that from Fig. 1 the utility model is made up of impactor 1, pulley 3, fixed head 4, impactor 1 and fixed head 4 all adopt epoxide resin material in the present embodiment; Two groups of pulleys 3 are between two fixed heads 4, and set bolt 2 is fixing with two fixed heads 4 and pulley 3; Fixed head 4 one ends have impactor 1 through bolt; Impactor 1 and pulley 3 are positioned at fixed head 4 tops, and fixed head 4 bottoms are provided with control hole 5, and control hole 5 is connected with rope, make the maintainer can carry out the stockbridge damper reset operation on ground.
Use the utility model to carry out the overhead ground wire stockbridge damper when resetting operation; Earlier climb up shaft tower by the maintainer; The stockbridge damper restorer of ultra-high-tension power transmission line overhead ground wire is placed on the overhead ground wire; Make overhead ground wire by passing between two fixed heads 4, pulley 3 can roll at overhead ground wire, and operation rope is fixed in the control hole 5.The maintainer is drag rope on ground; Make impactor 1 withstand the wire clamp of stockbridge damper; Stockbridge damper is pushed back to the normal position; Go up the fastening stockbridge damper wire clamp of shaft tower by the maintainer again, and pull down the stockbridge damper restorer of ultra-high-tension power transmission line overhead ground wire, under situation about not having a power failure, accomplish the stockbridge damper reset operation.
The equal insulating material of impactor of the utility model and fixed head is made, and simple in structure, cost is low, and flexible and convenient operation is practical.
