Description

Wire rod installation method for lightning protection of telegraph pole

The present invention relates to a wire installation device for preventing lightning strikes.

When the electric poles under high voltage are hit by lightning strikes, large-scale accidents (life and facility damage, etc.) occur, as well as power failures, which cause great damage to the industrial site, and general users also have to suffer a lot of inconvenience due to power failures. Many problems are to be expected. Therefore, conventionally, the tops of the telephone poles are connected to wires and used to prevent lightning, which may be regarded as a lightning rod. On the other hand, when connecting the top of the telephone poles with the wire as described above, it is difficult to connect more than 10 telephone poles at a time, because the biggest is because only the power outage was possible at work. That is, in the related art, a worker climbs up one pole of a telephone pole and uses a rope to lift the iron wire placed on the ground, and then fixes the wire on the top of the telephone pole, so there is no way to work safely without power failure. Therefore, working time was excessively consumed, work efficiency was low, and power outage time was too long.

Then, using a special vehicle (bucket vehicle) equipped with a bucket at the end of the ladder that can be pulled out and folded in an antenna type, the worker rides on the bucket, lifts the wire placed on the ground on the bucket, and fixes the wire on the top of the telephone pole. The method of mobilization was mobilized but it also had no effect compared to the above.

In the meantime, the following method was devised while searching for a way to fix the iron wire on the top of the telephone pole without power failure. That is, a bar can be fixed in advance to each telegraph pole at a position slightly lower than the tubular tubular body 102, and when the wire is hooked to the end of the bar, the wire slides and falls. The locking lever to prevent it is assembled. The bar is loaded on the bucket installed in the above-described bucket vehicle, and then the workers are lifted together to be installed on the telephone pole. And when the bar (Bar) is dismantled and lowered to the ground, and then loaded into the bucket, the workers descend together to move to the ground. Of course, there is no reason for power failure when the bar is installed. In this way, when a bar (Bar) is installed on each pole, the wires are lifted by the wires on the buckets, and then the wires are hooked on the latch bars of the bars. At this time, if a wire is caught in one latch, the vehicle moves at a low speed to the next telephone pole and stops. Immediately, the worker hangs the wire to the latch of the bar installed in the next telephone pole. After all of the wires are hung on the telegraph pole (BAR) designated by these tips, the bucket vehicle is moved to the leftmost telegraph pole or the rightmost telegraph pole among the designated telegraph poles, and then the wires are placed on the top of the support tube 101. For convenience of fixing, it will be described as working while moving from the left end to the right. At this time, the length of the wire is used to cut in advance by calculating the distance between the specified telephone poles, it is difficult to match the cutting length accurately has a disadvantage of a lot of loss of the wire. In the above-described conventional method, since the wire is cut and used in advance as described above, it is natural that there was a closed end as described below. In other words, if the length is longer or shorter than the required length, it is necessary to cut back to the proper length, so there are many unnecessary losses, heavy labor, and increased working time. Meanwhile, as described above, the bucket vehicle moves to the telegraph pole at the left end and then lifts the iron wire hanging on the bar fixed to the telegraph pole at the left end to the bucket. Next, the worker is to fix the wire to the top of the support tube 101, this time using the clamp 400 to connect the top of the support tube and the wire. The clamp 400 is a conventional device. Next, the bucket vehicle is moved to the telephone pole located on the far right side of the left side, and the iron wire is also lifted by the wire on the bucket, and then the iron wire is fixed on the top of the support tube. In this way, the wire is fixed on the top of the support tube to the pole next to the rightmost pole, and finally the wire is also fixed on the top of the rightmost pole of the support pole. Fix it using.

However, the above-described method has the following disadvantages and problems.

The time required to install a heavy weight and unmanageable bar on a telephone pole is dangerous for safety reasons, especially in the case of two or three wires and in the presence of transformers or branch lines. Because of the complexity, it is very difficult and dangerous to work through the inconvenient method as described above as well as the installation of the bar. In addition, there is a high risk that the wire or bar is in contact with the wire, causing sparks or shorts (or flashovers), which is a safety problem. In addition, it is difficult to work because of the need to be fixed to the support pipe after lifting the wire first to the bar (second) to the bar, and naturally there is a problem that the working time is long. In addition, it is difficult to dismantle the bar installed at the end of the work, and it is not easy to handle the heavy bar, and the fixed state of the wire is tight due to the nature of the work to cut the wire in advance. There is a disadvantage that the appearance is poor and thus the loss of the wire is increased accordingly.

Accordingly, an object of the present invention is to provide a wire rod installation device and method for preventing the lightning strike of the wire pole can be fixed to each support tube of the pole pole quickly and safely without a power failure.

Another object of the present invention is to provide a wire installing device and construction method for preventing lightning strike using the wire wire connected to a single strand without cutting the wire in advance and can be kept taut without sagging at the end of the work.

In order to achieve the above object, the present invention, a screw portion is formed on one side and the support plate is welded to the opposite side, and the chain gear fixed by bolts is assembled to the side of the support plate can be equipped with a roller wound around the wire One shaft 13; A fastener for fastening the roller by assembling a handle which can be turned by hand and a screw hole is formed at the center thereof so as to be assembled to the screw part of the shaft; A pillar 12 supporting the shaft 13; A disc holder configured to support the disc having the concentrically configured disc and another chain gear connected to the chain gear by the chain and to tighten or loosen the disc by a handle; A pillar 23 supporting the disk; A guide roller 29 which rotates while the shaft is fitted to the bushings on the pillars 27; A brace fixed to the upper surface of the pillar 70 by a bolt and a guide roller 72 assembled inside the brace; A rewinder (10) configured as a base on which the above devices are installed, and an reducer provided on one side of the engine and the guide roller (85); It is characterized by consisting of a coupling connecting the output shaft of the engine and the shaft of the reducer and a base to install them.

The guide roller 50 is assembled to the tubular body 102 installed on the telephone pole, and the guide roller 60 is assembled to the appropriate portion of the telephone pole.

An embodiment of the present invention will be described using the above components. However, the bucket vehicle used in the practice of the present invention has not been described in detail because it has already been described above. First, when a suitable telephone pole number is determined to perform the wire work as shown in FIG. 1 (in the present invention, seven telephone poles are described as an example), the rewinder 10 is installed next to the leftmost telephone pole and the wire 13 is attached to the shaft 13 ( Install the roller 200 on which 5) is wound. At this time, it is preferable that the vehicle 300 on which the winder 80 and the roller 301 are installed moves to the right side of the telephone pole on the right side and waits. At the same time, after installing the guide roller 60 on the leftmost telegraph pole and the rightmost telegraph pole, the worker rides on the bucket of the bucket vehicle and installs the guide roller 50 on the leftmost telegraph pole 102. The wire guide roller 30 is assembled to the top of the support tube 101. Subsequently, the wire guide rollers are assembled on the top of each support pipe while moving to the right pole, and the wire guide roller is assembled to the support pipe of the rightmost pole by moving to the right pole. Install 50. Next, the worker riding the bucket of the bucket vehicle grasps the end of the iron wire (5) wound on the roller 200 of the rewinder 10 and passes between the guide roller 60 and the guide roller 50, and at the same time, the left side of the bucket vehicle. Pass the end of the wire into the wire guide roller. Subsequently, while moving to the right, the wire passes through each wire guide roller and finally passes through the wire guide roller on the right side, and then passes between the guide roller 50 and the guide roller 60 on the right side. At this time, it is important to properly tighten the handle 26 of the disk holder 25 so that the roller 200 does not idle more than necessary, so that the wire 5 is released while maintaining the appropriate tension. At this time, the guide roller 29 serves to prevent the iron wire wound on the roller 200 to be released at a time, and to adjust the appropriate tension in the loose state of the iron wire. And because the guide roller 72 is rotated to the left and right from the column 71, the guide wire 72 is changed elastically even if the direction in which the wire is released. Next, while winding the end of the iron wire passing through the rightmost guide roller 50 to the roller 85 of the winder 80 and at the same time operating the engine to the wire to the roller 301 of the vehicle to each Pull out the wire that is passing between the wire guide rollers. Next, as shown in FIG. 10, the leftmost support tube and the rightmost support tube and both ends of the iron wire 5a are fixed through the clamp 400. Of course, the wire guide roller is already on top of the support tube as described above. It is natural that it is separated from. Next, the wire guide rollers assembled on the top of the remaining support tubes except for the leftmost and rightmost support tubes are separated. As described above, the knobs 40 assembled to the rollers 39 of the housing 37 are removed. Loosen the bolts 35 slightly while loosening the wires out of the housing 37 to simply separate the whole. Next, the wires are fixed to the top of the remaining support tubes except the left and rightmost support tubes through a separate fixing plate that can fix the wires. On the other hand, after connecting the leftmost and rightmost clamps with the wires, the unnecessary wires should be cut with a cutter. Next, the final separation of the guide rollers (50, 60) assembled in the leftmost and rightmost poles, the implementation of the present invention is finished as shown in FIG. 10, and then moved to the next work place as described above Repeat the same procedure as described.

The present invention as described above is easy to assemble only the minimum equipment (guide rollers, wire guide rollers) to the electric pole is conducting electricity and the rest of the equipment can be installed on the ground, even in the case of telegraph pole having a complex wire configuration There is no obstacle.

The present invention as described above, the light weight, easy to handle, and simple to the minimum structure of the electric pole that is electrically connected quickly and securely installed, using a winder and rewinder to fix the wire quickly and conveniently The workability can be significantly improved compared to the conventional method, as well as the safety features. In addition, it is not a method of cutting the wire in advance but using a single wire to fix the wire, so it is possible to minimize the unnecessary loss of the wire. It is effective to prevent safety accidents caused by sagging of steel wires.
