Lifting device used for building prefabricated slabs

Abstract

The invention relates to the technical field of building construction, and discloses a lifting device used for building prefabricated slabs. The lifting device comprises a fixed bottom plate, fixed columns are mounted at the upper end of the fixed bottom plate, a left rail is mounted at the upper end of the fixed column on the left side, a left rolling wheel is rotatably arranged at the upper endof the left rail, and a guide column is rotatably arranged in the middle of the left rolling wheel. A right rail is mounted at the upper end of the fixed column on the right side, a right rolling wheel is rotatably arranged at the upper end of the right rail, a rotating shaft is fixedly installed in the middle of the right rolling wheel, walking frames are installed at the two ends of the rotatingshaft through bearings, a motor plate is installed at the upper ends of the walking frames, a rotating motor is installed at the upper end of the motor plate, an output shaft of the rotating motor isconnected with a driving belt wheel, and the lower end of the driving belt wheel is connected with a driven belt wheel through a belt. According to the lifting device, lifting operation to the building prefabricated slabs is ensured, the lifting device has a power source and is good in maneuverability, the lifting range is further widened, and meanwhile the stability of the building prefabricatedslabs in the lifting process is ensured by arranging balance columns and balance wheels.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a lifting device for building prefabricated panels. Background technique [0002] On the construction site, it is often necessary to lift building materials or prefabricated panels from the ground to high places, and the lifting frames and hooks used for lifting are often unable to be fixed with the building prefabricated panels and panel materials, and it is impossible to lift buildings driven by motors Prefabricated panels and panel materials. [0003] The existing construction lifting frame design is relatively traditional, and its anti-seismic ability is poor, which makes it easy to be cracked when lifting heavy building materials, and due to the heavy weight of the plate and strong inertia, the ropes often break due to inertia .

[0002] On the construction site, it is often necessary to lift building materials or prefabricated panels from the ground to high places, and the lifting frames and hooks used for lifting are often unable to be fixed with the building prefabricated panels and panel materials, and it is impossible to lift buildings driven by motors Precast panels and panel materials

[0003] The existing construction lifting frame design is relatively traditional, and its anti-seismic ability is poor, which makes it easy to be cracked when lifting heavy building materials, and due to the heavy weight of the plate and strong inertia, the ropes often break due to inertia

The advanced shock absorbing equipment is not only too complicated in structure and high in cost, but also easy to damage and not strong in applicability. Moreover, when it is tied with ropes and hoisted with hooks, it will also fall off due to the uneven center of gravity of the board.

[0004] Chinese patent (publication number: CN211712419U) discloses a lifting frame for building prefabricated panels, including a fixed column and a lifting column, a first groove is opened in the center of the fixed column, and the first groove A first bearing is fixed inside, the inner wall of the first bearing is welded to the lower end of the lifting column, the top surface of the lifting column is welded with a lifting ring, and the two ends of the fixing column are located in the first groove Second bearings are welded on both sides, the inner walls of the two second bearings are welded to the fixing column, and the outer walls of the two second bearings are welded with fixing blocks, and the two fixing blocks run through the interior of the upper end and the second bearing. The outer wall of the bearing is welded, and the lower ends of the two fixed blocks are fixedly provided with mounting plates. Although this device can achieve the stability of lifting and transporting the building prefabricated panels to a certain extent, in actual operation, the device cannot Precast slabs perform efficient hoisting movements, therefore, further improvements are required
