防沉降防跳动的椭圆井盖制造技术
本实用新型专利技术公开了一种防沉降防跳动的椭圆井盖,包括井座和椭圆形的盖体,盖体与井座转动连接;在井座的安装槽口上设有上台阶和下台阶,在下台阶上嵌设有环形橡胶垫,在下台阶的内侧壁上固设有摩擦环;在盖体的底部设有主承载凸环,盖体的外边缘向外延伸形成次承载凸缘,在盖体的底部固接有多个弹性悬臂,在弹性悬臂的自由端设有摩擦头,该摩擦头与摩擦环适配卡合,摩擦头与摩擦环的横截面均为三角形。本实用新型专利技术的一种防沉降防跳动的椭圆井盖,减小了盖体的跨度、提高了其承载能力,符合人体形状特点、方便工人进出进行检修,椭圆盖体还方便识别;能防止盖体产生跳动,消除噪声,防止沉降。
Anti settling and anti jumping elliptical manhole cover
The utility model discloses a antisettling elliptic beating cover covers prevention, including a well seat and oval, the cover body is connected with a well seat is provided with a rotation; the steps and steps in the installation slot on the shaft, an annular rubber pad is embedded in the next step, on the inner wall of the lower level. A friction ring; the main bearing cap convex rings are arranged at the bottom of the body, the outer edge of the cover body extends outward to form a bearing flange, a plurality of elastic cantilever fixed on the bottom of the cover body is provided with a friction head, in the free end of the cantilever, the friction head and the friction ring adapter, cross section of friction the cleaning head and the friction ring are triangle. The utility model relates to a manhole cover against beating antisettling elliptic, reduces the cover span, increase the bearing capacity, accord with human body shape characteristics, convenient import and overhaul, elliptical cover is easy to identify; to prevent the cover body bouncing, eliminate noise, preventing settlement.
