Self-locking mute easy-to-open anti-settling manhole cover
The invention relates to the field of pipeline engineering, in particular to a self-locking mute easy-to-open anti-settling manhole cover which is composed of a well seat, a well seat rubber mat bearing platform, a pawl mounting wall, a manhole cover body and a city business card. The well seat lifting conical cylinder is aligned with the inspection well and put down, the well seat surface ring is adjusted to be flat with the road surface, the well seat lifting conical cylinder is fixedly connected with the roadbed body through the conical cylinder fixing screws, and the nodular cast iron anti-falling net is placed on the nodular cast iron anti-falling net bearing platform; the nylon anti-falling net is hung on the W-shaped anti-falling net hook, and the silencing pressure-resistant rubber mat is glued on the well seat rubber mat bearing platform; the shaft pin assembles the torsion spring and the pawls between the two pawl mounting walls, the T-shaped screw rod for jacking the well lid is pushed downwards to open the pawls, meanwhile, the self-locking pawls are retracted upwards, the pawl mounting walls are aligned with the pawl box to be put down, the torsion spring locks the self-locking pawls and the inner wall of the vertical ring without loosening, the T-shaped screw rod for jacking the well lid and the well seat can easily jack the well lid and the well seat, and pavement base materials are evenly paved below the well seat surface ring. The well seat and the road surface are adjusted to be flat, and the functions of well lid and well seat settlement adjustment, self-locking, silence, easy opening, theft prevention, settlement prevention, return surge prevention, safety, sealing and leveling are achieved.
本发明为自锁静音易开启防沉降检查井盖，涉及管道工程领域，由井座、井座胶垫承台、棘爪安装墙、井盖、城市名片五部分组成;井座升降锥筒对准检查井放下，调整井座面圈与路面平整，锥筒固定螺钉将井座升降锥筒与路基体紧固联接，球墨铸铁防坠网放置在球墨防坠网承台上；尼龙防坠网挂在W形防坠网挂钩上，消音耐压胶垫胶粘在井座胶垫承台上；轴销将扭簧、棘爪装配在两棘爪安装墙之间，顶升井盖T螺杆下推开启棘爪同时自锁棘爪上收，将棘爪安装墙对准棘爪箱放下，扭簧将自锁棘爪与竖圈内壁紧锁不松动，顶升井盖、井座的T螺杆可轻易将井盖、井座顶升，在井座面圈下均铺路面基材，调节井座与路面平整，实现井盖井座沉降可调节、自锁静音易开启、防盗防沉降防返涌、安全密闭平整功能。
