Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding equipment, in particular to an anti-skid device for scaffolding boards used in shipbuilding. Background Art

[0002] Scaffolding boards, also known as scaffolding sheets, are laid on scaffolding and operating frames to facilitate workers to walk on them, transfer materials and perform construction operations. Scaffolding boards can be made of steel, wood, bamboo, aluminum alloy, plastic and other materials. The weight of a single scaffolding board should not be greater than 30KG. Commonly used scaffolding boards on construction sites include stamped steel scaffolding boards, wooden scaffolding boards, and bamboo scaffolding boards. When using scaffolding boards, anti-slip equipment is required to prevent operators from slipping.

[0003] For example, the authorization announcement number is "CN210681091U", which is a scaffolding anti-skid device for shipbuilding. By adding a telescopic inner rod and a rotating rod fixing block, the angle of the pedal can be adjusted, so that the staff can work horizontally. However, the scaffolding anti-skid device for shipbuilding uses bolts to install the U-shaped plate on the scaffolding, but the operator needs to tighten the two bolts against the scaffolding separately, which increases the workload of the operator. At the same time, the telescopic inner rod and the telescopic outer rod of the scaffolding anti-skid device for shipbuilding can only be adjusted at a fixed height. When the anti-skid plate needs to be moved to a special height, the telescopic inner rod and the telescopic outer rod cannot be fixed, which increases the working limitations of the anti-skid device.
