Protective fence
The invention discloses a protective fence, and belongs to the technical field of safety protection equipment, the protective fence comprises two symmetrical foldable supporting rods, a steel rope winding and unwinding device is fixed on each foldable supporting rod, a steel rope is fixed on each steel rope winding and unwinding device, and the steel ropes of the steel rope winding and unwinding devices on the two foldable supporting rods are connected with each other; the foldable supporting rods have a vertical unfolding state and a transverse folding state, and when the foldable supporting rods are in the transverse folding state, the distance between the two foldable supporting rods is reduced, and the steel rope is contracted in the steel rope retracting and releasing device; when the foldable supporting rods are in a vertical unfolding state, a fence area is formed between the two foldable supporting rods through the steel rope, the technical problems that a protective fence occupies a large dam face space, storage is not convenient and fast, and the labor intensity of field fence operation is large are effectively solved, and the efficient and safe requirements of hydropower station dam face edge operation can be met.
本发明公开了一种防护围挡，属于安全防护设备技术领域，包括两根相互对称的可折叠支撑杆，每根可折叠支撑杆上固定有钢绳收放装置，钢绳收放装置上分别固定有钢绳，两根可折叠支撑杆上的钢绳收放装置的钢绳相互连接；可折叠支撑杆具有竖向展开状态及横向折叠状态，当可折叠支撑杆处于横向折叠状态时，两根可折叠支撑杆之间的间距减小，钢绳被收缩在钢绳收放装置中；当可折叠支撑杆处于竖向展开状态时，两根可折叠支撑杆之间通过钢绳构成围挡区，本发明有效解决了防护围挡占用坝面空间多、收纳不便捷和现场围挡作业劳动强度大的技术问题，能满足水电站坝面临边作业的高效与安全需求。
