The invention provides a manhole cover plate hoisting device and relates to the technical field of hoisting, a hoisting device body comprises a hoisting frame and a hoisting rope, two fixing plates are installed at the bottom of the hoisting frame, a connecting rod is arranged between the fixing plates, arc-shaped hoisting rails are installed at the two ends of the surface of each fixing plate, and the arc-shaped hoisting rails are connected with the hoisting rope. A lifting appliance is installed on the surface of the arc-shaped lifting rail, the bottom of the lifting rope is connected with the lifting appliance part, and independent anti-collision assemblies are installed at the two ends of each fixing plate. According to the lifting device, after the manhole cover plate body is locked through four connecting point positions at the bottom of the lifting frame, the manhole cover plate body can be completely consistent with the overall inclination angle of the lifting frame, and then the position of a lifting appliance can be changed in the lifting process by matching with an adjusting mechanism and a traction assembly; therefore, the purpose of accurately adjusting and controlling the inclination angle of the manhole cover plate body is achieved, the follow-up installation difficulty is reduced, the connection stability is improved, and meanwhile the edge of the manhole cover plate is protected.
本发明提供一种人孔盖板吊装装置,涉及吊装技术领域,吊装装置本体包括吊装架和吊装绳索,吊装架的底部安装有固定板,且固定板设置有两个,每个固定板之间设置有连接杆,固定板的表面两端均安装有弧形吊轨,弧形吊轨的表面安装有吊具,吊装绳索的底部与吊具部分相连接,每个固定板的两端均安装有独立的防撞组件。该吊装装置通过吊装架底部四处连接点位与人孔盖板本体锁定后使得人孔盖板本体能够与吊装架整体倾斜角度保持完全一致,进而配合调节机构和牵引组件即可在吊装过程中改变吊具位置,从而达到对人孔盖板本体倾斜角度进行精准调控的目的,降低了后续安装难度,提高了连接稳定性,同时也对人孔盖板边缘提供了保护。
