The invention discloses a sewer well lid lifting device, and relates to the technical field of sewer well lids. The adjusting mechanism comprises a base, the adjusting mechanism comprises a steering pipe, first rotating shafts which are symmetrically distributed are fixedly arranged on the outer side of the steering pipe, the ends, away from the steering pipe, of the first rotating shafts movably penetrate through the supporting plate, and a lead screw penetrates through an internal thread of the steering pipe; the power transmission mechanism drives the lead screw to rotate, the lead screw is matched with the steering pipe, so that the lead screw moves downwards in the steering pipe, the lead screw drives the clamping mechanism to move downwards and penetrate through the well lid hole to be clamped with the well lid, in this way, the situation that the lead screw is loosened due to loose connection with the well lid can be avoided, and the purpose of convenient clamping is achieved; the clamping blocks move into the grooves through the acting force of the clamping blocks and the inner wall of the well lid hole, the springs are compressed, after the connecting rods penetrate through the well lid hole, the elastic force of the springs drives the clamping blocks to reset, the clamping blocks are clamped with the well lid, in this way, the situation that the clamping blocks are loosened due to untight connection with the well lid can be avoided, and the purpose of convenient clamping is achieved.
本发明公开了一种下水道井盖起盖装置,涉及下水道井盖的技术领域;而本发明包括底座,调节机构包括转向管,转向管的外侧固定设有对称分布的第一转轴,第一转轴远离转向管的一端活动贯穿支撑板,转向管的内部螺纹贯穿有丝杆;通过动力传输机构带动丝杆转动,并通过与转向管配合,使得丝杆在转向管内向下移动,丝杆带动卡合机构向下移动并贯穿井盖孔与井盖卡合,这样就可以避免与井盖连接不紧密出现松脱的情况,从而达到方便卡合的目的;通过卡块与井盖孔内壁的作用力移入凹槽内,并压缩弹簧,连接杆贯穿井盖孔后,弹簧弹力带动卡块复位,使得卡块与井盖卡合,这样就可以避免与井盖连接不紧密出现松脱的情况,从而达到方便卡合的目的。
