Nodular cast iron well lid and preparation method thereof
The invention belongs to the technical field of well lids, and particularly relates to a nodular cast iron well lid and a preparation method thereof.The nodular cast iron well lid comprises a well base, one end of the well base protrudes to form a protruding base, a straight groove is formed in the protruding base, an annular groove is formed in the inner wall of the well base, a straight plate is rotationally connected into the straight groove of the protruding base, and a well lid plate is arranged at the outer end of the straight plate; a plurality of movable supporting rods and supporting protruding blocks are installed in the annular groove of the well base in the circumferential direction. The movable supporting rod comprises an arc-shaped rod body, one end of the arc-shaped rod body penetrates through a positioning rotary column, and a handle is arranged on the lower side of the other end of the arc-shaped rod body. The annular groove is additionally formed in the well base, the space of the annular groove is used for installing the rotatable movable supporting rod, after the movable supporting rod rotates to the center area of the well base, auxiliary supporting can be provided for the well lid plate, the supporting strength of the well lid plate is improved, anti-falling protection can be achieved, and unrelated personnel are prevented from falling accidentally; the movable support can be completely hidden in the annular groove, and access of maintainers is not affected.
本发明属于井盖技术领域，具体涉及一种球墨铸铁井盖及其制备方法，该球墨铸铁井盖包括井座，井座的一端凸出形成有凸座，凸座中开设有直槽，井座的内壁开设有环形槽，凸座的直槽中转动连接有直板，直板的外端设有井盖板，井座的环形槽中沿周向安装有多个活动支撑杆和支撑凸块；活动支撑杆包括弧形杆体，弧形杆体的一端穿设安装有定位转柱，另一端下侧设有提手。本发明通过在井座中增设有环形槽，利用环形槽的空间来安装可转动的活动支撑杆，活动支撑杆转动至井座的中心区后，能够为井盖板提供辅助支撑，提高井盖板的支撑强度，也可实现防坠保护，避免无关人员意外坠落；活动支撑可以完全隐藏在环形槽内，不会影响检修人员的进出。
