Anti-falling safe nodular cast iron well lid
The invention discloses an anti-falling safety type nodular cast iron well lid, and relates to the technical field of nodular cast iron well lids. According to the anti-falling safety type nodular cast iron well lid, through the arrangement of the protection bearing assembly, when the well lid body is stressed, supporting can be conducted through cooperation of the supporting platen and the multiple bearing columns, the phenomenon that the well lid body is damaged or falls is avoided, and when disassembly is needed or manual well descending maintenance is needed, the well lid body is not damaged; the well lid body can be pulled out through the hoisting grooves, then the supporting platen is pulled out upwards, the multiple bearing columns can be stressed to rotate along the limiting shafts, the bearing effect of the well lid body can be guaranteed, deformation and falling caused by too large stress are avoided, meanwhile, disassembly and maintenance operation is facilitated, and the subsequent maintenance convenience is improved; through the arrangement of the reinforcing assembly and the reinforcing convex plate, the connecting strength between the outer well ring and the roadbed is improved, and the phenomenon that the outer well ring falls off due to the fact that stress is too large is avoided.
本发明公开了一种防坠落安全型球墨铸铁井盖，本发明涉及球墨铸铁井盖技术领域。该防坠落安全型球墨铸铁井盖，通过防护承载组件的设置，能够使井盖本体受力时，通过支撑台板以及若干个承重柱的配合进行支撑，避免井盖本体出现受损或坠落的现象，需要拆卸时或需要人工下井维护时，可以将井盖本体通过吊装槽拉出，而后将支撑台板向上拉出，若干个承重柱能够受力沿限位轴转动即可，能够保证井盖本体的承重效果，避免受力过大出现形变、坠落的同时，便于进行拆卸维护作业，提升了后续的维护便捷性，通过加强组件的设置，通过加强凸板的设置，增加了外井圈与路基之间的连接强度，避免外井圈受力过大出现掉落的现象。
