Rotary orifice protection cover plate
The invention discloses a rotary orifice protection cover plate which comprises a fixed support, a rotary cover body and an annular rack, the rotary cover body is composed of a plurality of sub-cover bodies, and the annular rack is arranged in an annular guide groove of the fixed support and can slide along the annular guide groove; wherein a sliding rail is further fixed to the fixed support, the surface of the sliding rail is located above the annular rack, a plurality of support lug plates corresponding to the sub-cover bodies are further arranged on the outer side wall of the fixed support, rotatable cover plate gears are arranged on the support lug plates, the cover plate gears are meshed with the annular rack, and operation holes are formed in the tops of the cover plate gears. The sub-cover body is provided with a through hole corresponding to the operation hole in position, the bottom of the sub-cover body is further provided with a guide strip, and the guide strip penetrates through the sliding rail so that the sub-cover body can rotate along the operation hole. The device can effectively prevent tools from falling, meanwhile, opening and closing operation is simple and safe, multi-person matched lifting is not needed, and a single person can close and open a hole opening.
本发明公开了一种旋转式孔口防护盖板，包括固定支座、旋转盖体以及环形齿条，旋转盖体由多个子盖体构成，环形齿条设置在固定支座的环形导槽内，并能够沿环形导槽滑动；其中，固定支座上还固定有滑轨，滑轨的表面位于环形齿条的上方，固定支座的外侧壁上还设置有多个与子盖体对应的支座耳板，支座耳板上设置有可转动的盖板齿轮，盖板齿轮与环形齿条相互啮合，盖板齿轮的顶部开设有操作孔，子盖体上开设有与操作孔位置对应的通孔，子盖体的底部还设置有导向条，导向条贯穿滑轨，以供子盖体沿操作孔旋转。本发明能有效防止工器具坠落，同时启闭操作简单安全，无需多人配合起吊，单人即可完成孔口的封闭和开启。
