Examples

Fig. 1 is a schematic structural diagram of the laser positioning and scribing device for the wind power tower drum (installed on the tower drum) according to this embodiment, as shown in fig. 1, the scribing device includes a reference plate 11 having a reference line, an angle rotary table 12 rotatably connected to the reference plate 11, and a laser scriber 13 fixedly installed on the angle rotary table 12, the reference plate 11 is used for being fixed on the tower drum 2, after the reference plate 11 is fixed on the tower drum 2, laser lines 131 emitted by the laser scriber 13 can be projected onto a drum body of the wind power tower drum and form a cross line with the drum body, the cross line is an installation line of small pieces matched with the tower drum, and a worker installs the small pieces matched with the cross line. In this embodiment, the laser line 131 can be projected onto the nozzle end face 21 of the tower and forms an intersection with the nozzle end face 21.

The angle rotary table 12 is provided with measurement scales which can be used for measuring the rotation angle of the angle rotary table relative to the reference plate reference line; the laser scriber 13 fixed on the angle rotary disc 12 can rotate along with the rotation of the angle rotary disc, so that the laser line emitted by the laser scriber 13 can also rotate along with the angle rotary disc 12. The laser scriber 13 can emit a laser line coinciding with the reference line of the reference plate 11, after the reference plate 11 is fixed on the tower 2, the reference line on the reference plate 11 extends along the radial direction of the tower, and the central axis of the angle rotary table 12 coincides with the central axis of the tower, so that the scale on the angle rotary table 12 can measure the rotation angle of the laser line relative to the reference plate reference line.

After the reference plate 11 is fixed on the barrel body of the wind power tower barrel, the reference line of the reference plate 11 extends along the radial direction of the tower barrel, and the reference line of the reference plate 11 is used as the installation reference of small pieces matched with the tower barrel. The central axis of the angle rotating disc 12 is ensured to be coincident with the central axis of the tower, the laser scriber 13 is operated to emit a laser line coincident with the reference line of the reference plate 11, at the moment, the angle rotating disc 12 is at the initial position, and the rotating angle of the angle rotating disc relative to the reference line is displayed as 0 on the dial disc. When the small matched parts are required to be installed on the tower barrel body which forms a certain specific angle with the installation reference, the angle rotating disc is rotated and is displayed according to the scale of the angle rotating disc to enable the angle rotating disc to rotate through the specific angle, the laser line which is coincided with the reference line does not coincide with the reference line any more at the moment, the laser line rotates by the same angle along with the angle rotating disc, the laser line is projected on the tower barrel body to form a clear cross line with the barrel body, and the small matched parts are installed on the cross line, so that the small matched parts can be accurately installed to the preset angle relative to the installation reference.

Fig. 3 shows two perpendicular laser lines when the angle dial 12 is rotated 30 degrees relative to the reference line, and the laser line coincident with the reference line is no longer coincident with the reference line, but rather is rotated 30 degrees with the angle dial.

Further, the central axis of the laser scribing instrument 13 coincides with the central axis of the angle rotating disc 12, and after the scribing device is installed on the tower, the central axes of the laser scribing instrument 13, the angle rotating disc 12 and the tower 2 coincide.

Further, as shown in fig. 1, the reference plate 11 of the present embodiment is in a long strip shape, and two ends of the reference plate are respectively fixed on the tube opening end faces 21 opposite along the tube diameter of the tower tube.

When the laser positioning and marking device for the wind power tower cylinder is used, the reference plate of the marking device is installed on the tower cylinder body, the center shaft of the angle rotating disc is enabled to coincide with the center shaft of the tower cylinder, and the reference line of the reference plate extends along the radial direction of the tower cylinder. The laser scriber 13 is operated to emit laser lines which are coincident with the reference lines of the reference plate 11, the angle rotary disc is rotated, after scales on the angle rotary disc rotate for a certain angle, the laser lines which are coincident with the reference lines can rotate for the same angle, clear cross lines are formed between the laser lines and the barrel body, and the cross lines can be used as installation lines needing positioning. Workers only need to install the matched small pieces on the cross line, and the accuracy of the installation positions of the small pieces can be guaranteed.
