Auxiliary hoisting device for fabricated building

Abstract

The invention relates to an auxiliary hoisting device for a fabricated building, and belongs to the field of stiff steel rib hoisting. The auxiliary hoisting device comprises a carrying platform, a winding drum is fixed to the top of the carrying platform, a hoisting rope used for suspending a to-be-assembled cross steel rib is wound around the peripheral surface of the winding drum, the carrying platform is slidably connected with a first sliding plate in the length direction of the carrying platform, and a motor is fixed to the top of the first sliding plate. The carrying platform is slidably connected with a second sliding plate in the vertical direction. The opposite inner sides of the second sliding plate and the first sliding plate are provided with slopes correspondingly. Second springs are fixed to the bottom end of the second sliding plate, and the bottom ends of the second springs are fixedly connected with the carrying platform. A steering wheel is rotationally mounted at the top of the second sliding plate, and a lifting rope is wound on the peripheral side of the steering wheel. A driving assembly used for driving the winding drum to rotate is arranged between the motor and the winding drum. The auxiliary hoisting device has the effect that pay-off can be stopped after a to-be-assembled profile makes contact with the mounting plane.

Description

technical field [0001] The present application relates to the field of rigid steel frame hoisting, in particular to an auxiliary hoisting device for a prefabricated building. Background technique [0002] At present, during the construction process of prefabricated buildings, section steel needs to be hoisted; and rigid structure refers to pouring concrete on the outer layer of section steel after the assembly of section steel is completed to form a concrete rigid column. [0003] Related technologies can refer to the Chinese utility model patent whose authorized announcement number is CN206427970U, which discloses a new type of rigid steel column hoisting device, including a base, an inner cavity is opened in the base, and a first gear and a second gear are installed on the bottom surface of the inner cavity to rotate. Two gears, the first gear meshes with the second gear, the top of the first gear is fixed with a lead screw; the outer peripheral surface of the lead screw i...
