Auxiliary hoisting device for prefabricated building

Abstract

The application relates to an auxiliary hoisting device for prefabricated buildings, belonging to the field of stiff steel frame hoisting. It includes a loading platform, a reel is fixed on the top of the loading platform, and a cross-steel for suspending the to-be-assembled cross-steel is wound around the outer circumference of the reel. The lifting rope of the bone, the loading platform is slidingly connected with a first sliding plate along its own length direction; a motor is fixed on the top of the first sliding plate; the loading platform is vertically sliding connected with a second sliding plate; The sliding plate and the first sliding plate are respectively provided with inclined surfaces on the opposite inner sides; the bottom end of the second sliding plate is fixed with a second spring, and the bottom end of the second spring is fixedly connected with the loading platform; the top of the second sliding plate is rotatably installed with a second spring. The steering wheel, the hanging rope is wound around the circumference of the steering wheel; a driving assembly for driving the rotation of the drum is arranged between the motor and the drum. The present application has the effect of making it easy to stop the pay-off after the profile to be assembled is brought into contact with the installation 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 prefabricated buildings. Background technique [0002] At present, the prefabricated building needs to hoist the section steel during the construction process; and the rigid structure refers to pouring concrete on the outer layer of the section steel after the assembly of the section steel is completed to form a concrete rigid column. [0003] For related technologies, please refer to the Chinese utility model patent with the authorization announcement number 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 first gear are rotatably installed on the bottom surface of the inner cavity. 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 ...
