Description

Technical Field

[0001] The utility model belongs to the field of tower-type solar thermal power generation project construction, and specifically relates to an azimuth alignment device for a solar thermal hollow steel column. Background Art

[0002] During the installation of hollow steel columns, accurately adjusting their azimuth is a key step in ensuring project quality. Currently, the most common adjustment method relies on manual measurement and adjustment. Traditionally, a positioning fixture is fixed to the flange of the hollow steel column, a plumb line is drawn to adjust the distance to the east-west marking line, and then a ruler is used to measure the distance from the plumb line's center point to the east-west marking line to calculate the azimuth error. Due to the influence of wind, human factors, and other factors during the actual measurement process, the error is too large, resulting in inefficient installation and debugging of the heliostat lenses. This results in low precision, poor efficiency, and inconvenient operation. Therefore, a new azimuth adjustment device for hollow steel columns is needed to improve adjustment accuracy and efficiency and reduce construction costs. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] according to Figure 1-Figure 3 The device shown is a photothermal hollow steel column azimuth alignment device, comprising a flange 4, a handheld support rod and a laser emitting device, wherein the handheld support rod is connected to one side of the flange 4, and the laser emitting device is connected to the flange 4.

[0023] The flange 4 has bolt holes evenly distributed along the circumference, and a fixing rib is provided axially along the center of the circle. The laser emitting device is connected to one end of the fixing rib. Figure 1 The middle flange 4 must fit with the flange of the hollow steel column to ensure a tight fit with the flange surface of the inserted hollow steel column.

[0024] The laser emitting device includes an emitter bracket 5 and a laser emitter 6; the laser emitter 6 is connected to the emitter bracket 5, and one end of the laser emitter bracket 5 is welded to the fixing rib of the flange 4 along the axial direction, and the other end is welded to the center point of the central cut plane of two adjacent bolt holes on the edge of the flange.

[0025] There must be a reference point for adjusting the azimuth angle of the hollow steel column. There is a chamfered plane on the flange surface, which is the side surface of the center point of the two bolt holes of the flange. Figure 1 The welding center point of the laser bracket 5 on the upper portion of the center flange should be aligned with the adjustment point of the inserted hollow steel column, i.e., the center point of the cut surface. The laser emitter 6 is fixed to the laser bracket 5, ensuring that the laser emitter 6's radial point, the bracket's centerline, and the adjustment point (cut surface) are aligned.

[0026] like Figure 1 As shown, the handheld support rod is an inverted L-shaped hollow steel pipe, including a short side of the handheld support rod and a long side of the handheld support rod. One end of the short side of the handheld support rod is welded to the upper surface of the flange 4, and the other end of the short side of the handheld support rod is vertically connected to the long side of the handheld support rod.

[0027] The handle is constructed from a 30×30mm square hollow steel tube. Its short side (1) is designed to be 10cm long and tightly welded to the flange. The long side (2) has been designed to be 1m long after extensive testing. This length meets ergonomic requirements and ensures ease of handling. The square steel tube construction increases friction, preventing it from falling out of the hand during lifting.

[0028] Anchor bolts 3 are welded at the bottom of the flange. The anchor bolts 3 are conical and are inserted into the bolt holes on the upper flange surface of the inserted hollow steel column when in use. The conical anchor bolts can fully fill the bolt holes, reduce shaking, and make the measurement results more accurate.

[0029] When using, first debug the tooling, place the device on the flange of the inserted hollow steel column, insert the tapered anchor bolt into the bolt hole on the flange surface, and turn on the laser beam. Verify whether the azimuth angle after installation is consistent with the design coordinates by adjusting the laser emission point of the laser emitter. Adjust the laser emitter so that the laser beam point is consistent with the actual angle point of the RTK layout, and complete the tooling debugging work. When using, clamp the device to the flange of the inserted hollow steel column, and align the laser emitter with the cutting plane. Turn on the laser emitter, measure the difference between the laser point of the emitter and the design angle point of the RTK layout, and then calculate the value between the actual azimuth angle and the design azimuth angle.

[0030] In the absence of conflicts, those skilled in the art may combine the relevant technical features in the above examples according to actual circumstances to achieve corresponding technical effects. Specific descriptions of various combinations are omitted here.
