Technical Field

[0001] The present invention relates to the technical field of structural components, and in particular to a steel structure construction platform inside a wind power tower. Background Art

[0002] The wind turbine tower building is roughly a cone-shaped structure. Figure 9 As shown, elevators, cables, interior decoration, etc. will be installed inside the tower, so a temporary construction platform is needed as a support table for the operators.

[0003] Existing construction platforms are mostly welded or bolted. The outer diameter of the platform is relatively fixed and cannot adapt to the changes in the inner diameter of the tower at different heights. The outer periphery of the platform needs to be dismantled to adjust the outer diameter, which is relatively troublesome. In addition, the support plate is fixed by multiple bolts, and there is a risk of the bolts falling. The guardrails on the edge of the support platform are also mostly fixed metal components. The protection length cannot be adjusted with the changes in the outer diameter of the platform. For this reason, we propose a steel structure construction platform inside the wind turbine tower.

[0059] The working principle and use process of the present invention are as follows: when in use, according to the inner diameter of the wind turbine tower, the secondary beam 102 is extended from the inner side of the support block 104, and then the adjusting bolt 106 is tightened to lock the position of the secondary beam 102. At this time, the telescopic beam 1 can be hoisted to the inner side of the wind turbine tower through the hanger 6 and the rigging, and then the support plate 2 and the telescopic beam 1 are matched through the positioning block 9 and the positioning groove 105. At this time, the clamping block 201 is clamped into the inner side of the connecting groove 7 to lay multiple support plates 2. When laying, 1 to 5 support plates 2 can be laid as little as possible to form a gap 10 for construction workers to go up and down. After installation, according to the outermost support plate 2 side The arc length of the edge is determined by rotating the worm 510 to drive the worm wheel 509 to rotate, thereby rotating the reel 508 to release the cable 504. Through the self-locking between the worm wheel 509 and the worm 510, the length of the cable 504 can be quickly adjusted and locked. Then, the stop block 507 is rotated to make it parallel to the first column 501, and the stop block 507 is passed through the inner side of the installation groove 4 to make it contact with the lower surface of the support plate 2. At this time, the limiting ring 506 can be rotated downward to cooperate with the limiting ring 506 and the stop block 507 to clamp and fix it with the support plate 2, thereby completing the installation of the telescopic guardrail 5, which is easy to operate.
