The invention relates to the technical field of lifting devices, in particular to a cover lifting device for highway surveying and mapping construction. A cover lifting device for road surveying and mapping construction is used for lifting a well cover and comprises a positioning mechanism, a driving mechanism, a connecting mechanism, a position adjusting mechanism and a flexible rope. The positioning mechanism comprises a bottom ring, a first one-way piece, a first spring and a positioning ring. The driving mechanism comprises a magnetic ring, a driving cylinder and a connecting cylinder. The connecting mechanism is used for promoting the connecting cylinder to synchronously rotate along with the driving cylinder after the connecting cylinder is separated from the magnetic ring. The position adjusting mechanism is used for enabling the connecting cylinder and the well lid to be coaxial when the driving cylinder rotates. According to the cover lifting device for road surveying and mapping construction, by arranging the position adjusting mechanism, the axis of the whole driving mechanism can be made to be coaxial with the well lid before the well lid is opened, so that the well lid cannot incline when being opened, the well lid and the edge of the well lid are prevented from being abraded, and personal injuries caused in the well lid opening process can be avoided.
本发明涉及提升装置技术领域,具体涉及一种公路测绘施工掀盖装置。一种公路测绘施工掀盖装置,用于起吊井盖,包括定位机构、驱动机构、连接机构、位置调整机构和柔性绳。定位机构包括底环、第一单向件、第一弹簧和定位环。驱动机构包括磁力环、驱动筒和连接筒。连接机构用于在连接筒与磁力环脱离后促使连接筒随驱动筒同步转动。位置调整机构用于在驱动筒转动时促使连接筒与井盖同轴。本发明的一种公路测绘施工掀盖装置通过设置位置调整机构,能够在打开井盖之前先促使整个驱动机构的轴线与井盖同轴,使得井盖打开时不会倾斜,防止井盖和井盖的边缘处磨损,且能够避免在打开井盖的过程中造成人身伤害。
