[0002] Guardrails are used in various constructions. Their main function is to prevent people from falling over or climbing over, thus improving safety. Safety warning guardrails are guardrails used at construction sites. During the construction of wind turbine towers, the on-site environment is relatively complex and dangerous. Normally, non-construction personnel are prohibited from entering the construction site. Therefore, safety warning guardrails are needed to warn and block non-construction personnel.

[0003] However, currently available safety warning guardrails are mostly fixed integrated structures, which take up a large space when carried, are time-consuming and labor-intensive to carry, and have defects. Utility Model Content

[0006] Preferably, the four corners of the supporting leg are provided with insertion holes, and fixing nails are slidably inserted into the insertion holes.

[0007] Preferably, a rotating block is fixedly connected to one end of the threaded rod away from the connecting sleeve.

[0008] Preferably, a limiting plate is slidably inserted on the movable plate, and one end of the limiting plate is fixedly connected to the outer wall of the connecting sleeve.

[0009] Preferably, an axle pin is inserted at the intersection of the two railings.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The safety warning guardrail for the construction of the foundation ring of the wind turbine tower causes the slide plate to move in the connecting sleeve by pulling the two cross plates. At the same time, the two guard plates move in a cross shape to drive the slide block to move on the load-bearing rod. Then the threaded rod is rotated. When the threaded rod rotates, the movable plate threaded on it will move along to cause the plug plate to be inserted into the slot on the slide plate to fix the position. The two cross plates are unfolded, and then the hooks on the two ends of the cross plates are respectively hung in the positioning plates on the columns, and the columns are used to support them. The utility model is a split assembly structure as a whole, which can not only greatly compress the occupied space and facilitate carrying, but also is simple and convenient to assemble on site, and is suitable for popularization and use.
