Conventionally, coating of a long strip material such as a cable-stayed bridge cable requires the use of an aerial work vehicle,
Since many temporary scaffolds are provided, it takes a lot of man-hours and time, and it becomes a dangerous work, resulting in poor work efficiency and a significant increase in cost. The present invention was developed in order to address the above-mentioned problems, and its object is to allow it to be mounted on a long member to be coated so that it can be run and coated by remote control. The purpose is to provide a coating device for long members, which has significantly improved coating performance and efficiency.

The coating supply mechanism 7,8
This is a coating device for a long member provided with 12 sets of coating members connected to 9 and 10 and a remote control mechanism 16, 25, 26a, b.

The casing 1 and the cover 13 have a structure which can be divided into two parts by a connecting fitting 5, bolts, etc., and are detachably fitted to the outer periphery of the long strip 24 to run. The traveling roller 3 is disposed so as to be able to move forward and backward with respect to the outer peripheral surface of the long member 24 by a link mechanism 4 disposed inside the casing 1, and is pressed against the outer peripheral surface of the long strip 24 by the pressing cylinder 2. They rotate in contact with each other, and a plurality of sets are arranged in the circumferential direction and the axial direction as shown in the figure to facilitate the running.

The paint supply mechanisms 7, 8, 9 and 10 include an accumulator 7, a paint tank 8, a solenoid valve 9 and a paint supply pipe 1 which are mounted in series outside the casing 1 and the cover 13.
0, etc., and the paint in the paint tank 8 is passed through the solenoid valve 9 and the paint supply pipe 10 by the accumulator 7 to each coating member 1
2 are continuously supplied. The coating member 12 is formed of a roller made of a sea-line-shaped liquid-absorbent material, and has a casing 1
Is movably attached to the end of the long member 24, is elastically contacted by the spring 11 to the outer peripheral surface of the long member 24, and is connected to the paint supply pipe 10 to rotate the supplied paint to rotate the long strip member 24. Apply to the outer peripheral surface of. As shown in FIG. 1, a plurality of long strips 24 are provided over the entire circumference, the entire circumference is coated, and the long strip 24 is covered with a cover 13 connected to the end of the casing 1.

The remote control mechanism 16, 25, 26a, b
Is a pulling wire 16, 1 connected to the front and rear sides of the casing 1 and the cover 13 as shown in FIGS. 1 and 3.
