Stepless lifting manhole cover
The invention belongs to the technical field of municipal administration, and relates to a stepless lifting manhole cover which comprises a manhole seat and a cover cap, the outer wall of the manhole seat is provided with a manhole seat external thread, the inner wall of the cover cap is provided with a cover cap internal thread, the cover cap internal thread can be in threaded fit connection with the manhole seat external thread, and the cover cap is provided with an inspection opening movable cover plate in a covering mode; a plurality of positioning pin piece inserting holes are formed in the edge of the upper bottom face of the cover cap, the well base external threads are constructed into multiple sections of discontinuous threads, the number of the positioning pin piece inserting holes is consistent with the number of the discontinuous threads on the outer wall of the well base, and the positioning pin piece inserting holes are overlapped with the circumference of the well base external threads in the vertical direction. And the distance from the positioning pin insertion hole to the circle center of the cap is equal to the distance from the circle center of the well seat to the well seat external thread. The manhole cover can economically and safely solve the technical problem that the elevation of the manhole cover needs to be steplessly lifted in the processes of newly building a road, using the road for a long time, secondarily paving the road and the like, and can achieve safe locking of the steplessly-lifted cover cap through the positioning pin piece.
本发明属于市政技术领域，涉及一种可无级升降的检查井盖,包括井座和盖帽，所述井座的外壁设置井座外螺纹，盖帽的内壁设置盖帽内螺纹，所述盖帽内螺纹能够与井座外螺纹螺纹配合连接，盖帽上盖合设置检查口活动盖板；所述盖帽的上底面边缘设置若干个定位销片插孔，所述井座外螺纹构造为多段间断螺纹，定位销片插孔与井座外壁的螺纹间断数量一致，定位销片插孔在竖直方向上与井座外螺纹的圆周重叠，定位销片插孔到盖帽圆心的距离与所述井座的圆心到井座外螺纹的距离相等。该检查井盖能够经济安全地解决在道路新建、道路长期使用、道路二次铺装等过程中需要无级升降井盖高程的技术问题，并能够通过定位销片实现无级升降盖帽的安全锁止问题。
