The invention relates to a hoisting mechanism suitable for obliquely arranging a manhole cover at an arc-shaped sealing head, and the hoisting mechanism comprises a support, a rotating arm, a sliding mechanism, a lifting hook mechanism and a sliding position adjusting mechanism, the support comprises a base plate, a vertical bracket, an oblique bracket and a first supporting plate; the rotating arm comprises an I-shaped supporting beam, a second supporting plate arranged at one free tail end of the I-shaped supporting beam and a mounting plate arranged at the other free tail end of the I-shaped supporting beam, and the second supporting plate of the rotating arm is rotatably connected with the first supporting plate of the support; a first limiting piece and a second limiting piece are arranged in the I-shaped supporting beam so that the sliding mechanism can slide between the first limiting piece and the second limiting piece, the sliding position adjusting mechanism comprises an adjusting screw rod and an adjusting nut, one free tail end of the adjusting screw rod is fixedly connected with the sliding mechanism, and the other free tail end of the adjusting screw rod is fixedly connected with the sliding mechanism. And the other free tail end of the adjusting screw rod penetrates through the mounting plate and then is matched with the adjusting nut, so that the safety performance is greatly improved.
本发明涉及一种适用于弧形封头处斜向设置人孔盖的吊装机构,包括:支座、转臂、滑行机构、吊钩机构及滑行位置调节机构,所述支座包括:垫板、竖向支架、斜向支架及第一支撑板,所述转臂包括工型支撑梁、设置于工型支撑梁其中一个自由末端的第二支撑板及设置于工型支撑梁另一个自由末端的安装板,转臂的第二支撑板与支座的第一支撑板之间形成可转动连接,工型支撑梁内设有第一限位件及第二限位件从而使得滑行机构在第一限位件与第二限位件之间滑行,所述滑行位置调节机构包括:调节螺杆及调节螺母,所述调节螺杆的其中一个自由末端与滑行机构固定连接,所述调节螺杆的另一个自由末端穿过安装板后与调节螺母相配合,从而大大提高了安全性能。
