Automatic overturning device for fabricated precast components

Abstract

An automatic overturning device for fabricated prefabricated components, comprising a chassis, a sliding support, a track, an anti-overturning vertical rod, an anti-overturning horizontal rod, a detachable supporting base, a magnetic rubber pad, an overturning frame, a hydraulic cylinder and a hydraulic control system. The device has the following effects: the prefabricated component can be hoisted and laid flat on the sliding support by a crane, the hydraulic system can overturn the overturning frame and the prefabricated component to a position with an angle of 0-90 degrees with the horizontal plane. The overturning process does not need to cooperate with the operation of the overhead crane through a steel wire rope, and the work efficiency is greatly increased. The magnetic rubber pad can protect the bottom of the prefabricated component in the process, but it is not used as the fulcrum of overturning, so the overall prefabricated component will not be damaged in the overturning process. The lifting ring at the top of the prefabricated component does not participate in the overturning process, and will not be deformed due to lateral shear force, so the structural integrity of the prefabricated component and the safety of subsequent hoisting are reliably guaranteed.

Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated component production equipment, specifically relating to an automatic flipping device for prefabricated components. Background Technology

[0002] In recent years, with the rapid development of prefabricated buildings in China, the prefabrication of concrete structural components for prefabricated buildings has become a key link in the prefabricated building industry chain. Prefabricated concrete structural components for prefabricated buildings mainly include two categories: horizontal components (composite slabs, composite beams) and vertical components (wall panels, columns). Prefabricated composite slabs are mostly produced using a continuous production line method, while other components, especially sandwich insulated exterior wall panels and irregularly shaped components, are mainly produced using a fixed mold platform method. Vertical components, especially wall panels, are produced horizontally but are used vertically. To ensure minimal deformation of the wall panels during storage, they must be stored vertically. Therefore, smoothly rotating the wall panels from a horizontal to a vertical position is a crucial step in the prefabrication process.

[0003] The existing fixed-mold method for producing precast components has the following problems with component flipping: 1) Flipping vertical components after demolding is done simultaneously using wire ropes and overhead cranes, resulting in low work efficiency; 2) When flipping precast components such as exterior wall panels on the ground, the lower part of the precast component, as the flipping fulcrum, is prone to severe damage, affecting the quality of the precast component; 3) Using the pre-reserved lifting rings as lifting points during flipping, the lifting rings are subject to lateral shear forces, easily causing severe deformation, thus creating safety hazards during the hoisting and installation of precast components; 4) Flipping irregularly shaped components, eccentric components, U-shaped wall panels, L-shaped wall panels, bay window wall panels, etc., is difficult, and instability during flipping can cause safety hazards; 5) Existing flipping machines cannot achieve 90-degree vertical flipping, requiring manual climbing to remove the overturning device after flipping, thus increasing operational hazards; 6) Existing precast component flipping machines have limited functionality and versatility, therefore they are not suitable for flipping all types of vertical components. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide an automatic flipping device for prefabricated components.

[0005] To achieve the above objectives, the automatic tilting device for prefabricated components provided by this utility model includes: a base frame, a sliding bracket, rails, anti-tipping uprights, anti-tipping crossbars, a detachable support base, magnetic rubber pads, a tilting frame, a hydraulic cylinder, and a hydraulic control system; wherein, the base frame is composed of a rectangular frame at the bottom and a cuboid frame on the top surface of the rectangular frame; the front of the bottom of the tilting frame is hinged to the front edge of the cuboid frame; two rails are installed laterally along the base frame at the front and rear of the tilting frame respectively; the sliding bracket is installed on the two rails and can be adjusted laterally on the rails to accommodate different types of prefabricated components and ensure their tilting stability, and is used to place prefabricated components; the detachable support base is vertically arranged, and the lower end of at least one detachable support base is installed on the front edge of the tilting frame; multiple magnetic rubber pads are magnetically attached to the detachable support base. On the inner side, and on the outer end face, it contacts the bottom of the precast component to prevent the bottom of the precast component from rigidly contacting the detachable support base during the flipping process, thereby playing a buffering role to protect the tongue and groove of the bottom of the precast component from being damaged; the lower ends of the two anti-tipping uprights are hinged to both sides of the rear edge of the flipping frame; the rear ends of the two anti-tipping crossbars are installed on the upper part of the two anti-tipping uprights in a height-adjustable manner, and the front part is located above the sliding bracket to clamp the front part of the precast component to prevent the precast component from flipping outward and falling during the flipping process, and it is suitable for precast components of different thicknesses; during the erection and hoisting of the precast component, the anti-tipping uprights and anti-tipping crossbars will automatically unlock and disengage through the hinge shaft; the hydraulic cylinders are tilted, and the upper and lower ends of the two hydraulic cylinders are respectively hinged to the front of the bottom of the flipping frame and both sides of the bottom rear end of the cuboid frame, and are connected to the hydraulic control system through hydraulic pipelines.

[0006] The base frame is a steel structure and serves as the foundation of the entire device, supporting the tilting frame and its superstructure, as well as bearing the external forces applied by the prefabricated components.

[0007] The detachable support base consists of one or more sections. When there are multiple sections, the upper and lower sections are connected by bolts to accommodate prefabricated components of different thicknesses.

[0008] The sliding support has a variety of different widths and thicknesses to accommodate different types of prefabricated components.

[0009] The upper part of the anti-tipping upright has multiple round holes spaced vertically. The rear end of the anti-tipping crossbar is provided with a collar that fits over the outside of the anti-tipping upright, and the collar is also provided with round holes. The rear end of the anti-tipping crossbar is fixed to the anti-tipping upright by means of an adjusting screw passing through the round hole on the collar and a round hole on the anti-tipping upright.

[0010] The automatic tilting device for prefabricated components provided by this utility model has the following advantages: Compared with the prior art, this device can use a crane to lift the prefabricated components and place them flat on the sliding support. The hydraulic system can tilt the tilting support and the prefabricated components to a position with an angle of 0° to 90° with the horizontal plane. The tilting process does not require the cooperation of wire ropes and overhead cranes, greatly increasing work efficiency. During this process, the magnetic rubber pads can protect the bottom of the prefabricated components, but do not serve as fulcrums for tilting. Therefore, the prefabricated components will not suffer structural damage during the tilting process. The lifting rings at the top of the prefabricated components will not deform due to lateral shear forces because they are not involved in the tilting process. The structural integrity of the prefabricated components and the safety of subsequent hoisting are reliably guaranteed. The anti-tipping crossbars and uprights lock the prefabricated components to prevent them from slipping off the sliding support. After tilting, the prefabricated components placed vertically are stored in the vertical storage area using a crane. The anti-tipping device will automatically unlock during the lifting process. The sliding bracket, combined with the detachable support base, can adapt to the multi-purpose flipping needs of prefabricated components such as bay window wall panels, L-shaped wall panels, and U-shaped wall panels, thereby increasing the integrity and stability of the side walls and bay windows with the wall during the flipping process.
