The invention discloses a quick well lid opening device, and relates to the technical field of well lid opening. The device comprises a moving support, a rotating strip is rotationally matched in the moving support, two sliding arms are oppositely and slidably matched at the bottom end of the rotating strip, a driving mechanism used for driving the two sliding arms to slide oppositely is arranged in the rotating strip, and a connecting frame and a connecting base are vertically arranged below the sliding arms in a sliding mode. A second electric push rod drives a connecting base to move towards a connecting frame, first transmission plates and second transmission plates are driven to be rotationally matched below a well lid, the lengths of the two first transmission plates and the two second transmission plates in the horizontal direction are increased, and the two first transmission plates and the two second transmission plates exceed the length direction of reserved holes in the well lid; and then a first electric push rod is started to drive a connecting frame, a connecting base, a first transmission plate and a second transmission plate to move upwards, the first transmission plate pulls the well lid to move upwards, and then the well lid can be rapidly opened.
本发明公开了一种快速开井盖装置,涉及井盖开启技术领域。本发明包括移动支架,移动支架内转动配合有转动条,转动条底端相向滑动配合有两滑动臂,转动条内设有用于驱动两滑动臂相向滑动的驱动机构,滑动臂下方设有竖向滑动有连接架、连接座。本发明通过第二电动推杆驱动连接座向连接架移动,带动第一传动板、第二传动板在井盖下方转动配合,增加两第一传动板、两第二传动板,在水平方向的长度,并使两第一传动板、两第二传动板超过井盖上的预留孔的长度方向,然后开启第一电动推杆驱动连接架、连接座、第一传动板、第二传动板上移,第一传动板拉动井盖上移,进而便于快速打开井盖。
