Description

  The present invention relates to a curing device on a bend when painting between arms on a bend in a power transmission tower and a curing method on a bend using the same.

  Power transmission towers are regularly painted by brushing to prevent rusting, but paint (paint) often drops from the brush during painting, and when paint falls from a high place, wind, etc. There is a risk of scattering outside the tower due to the influence. Therefore, when painting a steel tower in an urban area, the painting work was performed after the railway line was stopped and the entire power transmission tower was surrounded by a curing net for preventing paint from scattering.

However, in the configuration surrounding the entire power transmission tower, there is a problem that the curing net becomes large in addition to the necessity of stopping the track. For this reason, a curing device and a curing method capable of reducing the size of the curing net by surrounding a part of the periphery of the steel tower body with a curing net and moving the position of the curing net vertically according to the position to be painted. Have been proposed (see, for example, Patent Documents 1 to 3).

  However, these proposed curing devices and curing methods are effective for painting under the arm of the steel tower, but interfere with the power transmission line on the bend, especially in the vicinity of the arm or on the arm. So it can not be adopted.

  In addition, painting work may be temporarily suspended on steel towers for safety reasons due to sudden changes in weather. When the painting operation is temporarily interrupted, it is desirable to temporarily overlap the curing net.

  Therefore, the present invention provides a curing device on a bend that can eliminate the need to stop the track when painting the tower portion between the arms on the bend of the transmission tower, and that can deploy and superimpose the curing net, and uses the same. The purpose is to provide a curing method on the bend.

  The present inventors, when curing the tower body between the arms on the bend of the transmission tower, adopt a curing net that can be expanded and superimposed in the vertical direction between the arms, so that between the arms We thought that we could provide a curing device that can deploy and superimpose a curing net. Also, in this case, if the setting position of the curing net that is deployed in units of planes is set within a range that complies with the predetermined standard distance, it may be possible to perform the painting work safely even if the line stop is unnecessary. It was.

  That is, the present invention is a curing device that develops a curing net for preventing splashing of paint splashes when painting a tower part between arms on a bend in a power transmission tower, and is developed vertically in plane units. -A rectangular insulating curing net that can be superposed, and the curing net is developed and superimposed vertically along the surface of the tower body, spaced from the tower body so that a standard distance can be observed, A fixing tool for fixing the curing net to the outside of the tower body part so that the position of the curing net can comply with the standard distance with the curing net deployed. It is a curing device on the bend characterized by.

  Further, the present invention is a curing method on a bend using the curing device described above, in which the tower portion between the arms is painted in a state where the curing net is deployed between the arms, and temporarily painted. In the curing method on the bend, the curing net is fixed to the tower body with the curing net superimposed, and the curing device is recovered at the end of the painting operation.

  Here, as the curing net, an insulating hanging rope is fixed to both ends of the tip, and a fastening member (for example, a small rope) to the tower body is fixed to the base end edge, and to both side edges. An annular guide member such as a carabiner for deploying the curing net in the vertical direction is preferably provided at a predetermined interval.

It is preferable to be composed of a vertical rope (guide rope) fixed in the direction (vertical direction). A carabiner of a curing net is inserted into such a vertical rope, and the curing net is guided by the vertical rope and can be expanded or superposed in the vertical direction.

  The hanging rope can lift the curing net by remote control from below via a pulley or the like suspended from an upper protruding fixing member. Further, when the painting operation is temporarily interrupted, the curing net can be superimposed by loosening the hanging rope.

  If the superposed curing net is temporarily fixed to a tower portion or the like by a fastening member (small rope), it can cope with gusts and the like. Also, at the end of the painting operation, all of the curing device is collected.

  According to the present invention, by adopting a curing net that can be expanded and superimposed in the vertical direction in units of planes, the curing net can be expanded and superimposed at the tower portion between the arms on the bend of the transmission tower. Moreover, since the extension position of the curing net that is developed in the vertical direction in units of planes is set within a range that complies with a predetermined standard distance, the painting work can be performed safely even if the line stop is unnecessary. As a result, when painting the tower section between the arms on the bend of the transmission tower, it is not necessary to stop the track, and the curing device on the bend that can deploy and superimpose the curing net, and the bend using the same.
