The invention relates to the technical field of municipal engineering, and discloses a novel anti-jumping manhole cover. The novel anti-jumping manhole cover comprises a concrete floor, a well base, bolts and a manhole cover, wherein an interlocking groove is formed in the inner side of the top of the well base, a buckling groove is formed in the middle of the well base, an extrusion bulge is arranged in the middle of the buckling groove, symmetrical movable cavities are formed in the well base, and lifting blocks are movably connected to the interiors of the movable cavities in a sleeving mode. According to the novel anti-jumping manhole cover, the manhole cover and the well base are designed, when the manhole cover is placed on the well base, under the gravity effect of the manhole cover, the manhole cover is pressed downwards and is affected by the extrusion bulge on the well base, hydraulic oil in the manhole cover flows into a self-locking cylinder, so that a driven rod is pressed downwards to lose extrusion force on a pull rope, a self-locking rod pops up, and in the continuous pressing process of the manhole cover, the self-locking rod is clamped into the interlocking groove so as to enable the manhole cover and the well base to form a cross interlocking relation, so that the periphery of the manhole cover is evenly stressed, and the problems that one end of the manhole cover is pressed downwards, the other end of the manhole cover is tilted, and the manhole cover bounces are avoided.
本发明涉及市政工程技术领域,且公开了一种防跳动的新型下水道井盖,包括水泥地、井座、螺栓、井盖,所述井座的顶部内侧开设有互锁槽,所述井座的中部开设有扣合槽,所述扣合槽的中部设有挤压凸起,所述井座内开设有对称的活动腔,所述活动腔内活动套接有抬升块。本发明通过设计的井盖、井座,使井盖在放在井座上时,在井盖的重力作用下,井盖下压并受到井座上的挤压凸起影响,使井盖内的液压油流入自锁缸内,从而使被动杆下压失去对拉绳的挤压力,使自锁杆弹出,并在井盖的持续下压中,自锁杆卡入互锁槽内使井盖与井座形成十字互锁关系,从而使井盖的四周受力均匀,避免井盖出现一端下压一端翘起,出现井盖弹动的问题。
