The device aims at solving the problems that in the wire changing construction of the existing overhead ground wire replacement, the construction time is long, the required personnel are many, and the investment is high. The device comprises two PPR pipes, two insulation ropes and four steel chisel ground anchors, wherein the middle part of each insulation rope is respectively sheathed with one PPR pipe, and one end of each insulation rope is respectively connected with one steel chisel ground anchor. The device is used for replacing overhead ground wires.
Description
Technical field
The utility model relates to the high voltage overhead power transmission sequence and changes the overhead ground wire device, is specifically related to utilize PPR pipe hanging carrying out high voltage overhead power transmission sequence to change the overhead ground wire device.
Background technology
Along with the lifting of china's overall national strength and the development of power network, especially after the principles and policies of the pulling domestic demand of stabilizing the economy are put into effect, drop into huge fund aspect the infrastructure construction of railway, high-grade highway and power circuit, radiating surface spreads all over all parts of the country.High voltage circuit overhead ground wire replacing rebuilding construction often runs into the problem with railway, highway and power circuit scissors crossing.Usually change in the overhead ground wire thread-changing construction methods of taking crossing frame or using crane colligation goat's horn bar and tension force to put stringing that adopt more.The weak point of taking the method for crossing frame is to prepare material complexity, length consuming time, and required personnel are many, transportation difficulty, time and effort consuming; Use the method for crane colligation goat's horn bar, though easy, also exist and be subjected to the influence of topography big, meet that crossover point is many, construction time, crane used platform, machine-team excessive cost fund to pay too high shortcoming when longer; Tension force is put stringing requirement plant equipment advanced person, invests hugely, and landform also will be fit to the expansion of plant equipment.When running into special location leap railway, highway, power line, crossed over by crane that landform limits and to use and can not set up fully crossing frame and use tension force to put line tightening method leap construction.And railway transportation is frequent, can not stop transport because of crossing over construction; The highway car flow is big, seals road construction infection traffic and is difficult to and realize; Striden power circuit and had a power failure, directly influenced user's productive life, also reduced the reliability of power supply simultaneously, influenced the economic benefit of power supply enterprise.
The utility model content
The utility model is changed the problem that the engineering time is long, required personnel are many, investment is huge in the overhead ground wire thread-changing construction for solving to have now, and then proposition utilizes PPR pipe hanging carrying out high voltage overhead power transmission sequence to change the overhead ground wire device.
The utility model is to address the above problem the technical scheme of taking to be: device described in the utility model comprises that two PPR pipes, two thoroughly do away with edge rope and four drill rod earth anchors, the middle part of every eradication edge rope is PPR pipe of each suit respectively, and whenever each is connected with a drill rod earth anchor end of restricting with insulation respectively.
The invention has the beneficial effects as follows: using the present invention to change overhead ground wire only needs two people to get final product, and has reduced labour's input, has saved the engineering time, and the present invention is simple in structure, and is easy to operate, and fund input is few, has saved a large amount of costs; It is constant to have reduced the resident living that causes because of long-time power failure, and factory and enterprise etc. is with the economic loss of electric unit, can also improve the power supply reliability of power supply enterprise, when also having reduced simultaneously because of construction to the appearance and the security implication of traffic routes such as highway, railway.

Operation principle
Use the utility model change overhead ground wire concrete steps as follows:
Step 1, crossed over the thing both sides above parallel wire on respectively hang a PPR pipe 1 respectively;
It is 1 parallel that the two ends of step 2, the every eradication edge rope 2 of traction are managed two PPR;
The replacing of promptly finishing overhead ground wire after thing both sides shaft tower wire clamp installs is crossed in step 4, the unwrapping wire that carries out overhead ground wire on two PPR pipe 1 and stringing operation;
Step 5, will change the overhead ground wire device and remove.
