Description

Technical Field

[0001] The utility model relates to the technical field of turnover devices, in particular to a mobile turnover device for concrete and prefabricated components. Background Art

[0002] Precast concrete components are prefabricated concrete products manufactured in a factory or on a specific site. They are made by mixing cement, aggregates, water, and admixtures according to a specific mix ratio, pouring them into molds, and curing to harden. Common examples include precast beams, columns, slabs, wall panels, and stairs. Precast concrete components offer numerous advantages, including high construction efficiency, consistent quality, resource savings, and improved building performance. Their factory-based production is unaffected by weather and site conditions, allowing for rapid installation and significantly reducing on-site construction time and workload. Standardized production ensures consistent quality and is rigorously tested. This reduces on-site work and construction waste, improving material utilization. High dimensional accuracy, with high-precision joints ensuring structural quality, is achieved. Precast concrete components have a wide range of applications. In residential construction, they can be used to construct floor slabs and wall panels, speeding up construction and improving building quality. In bridge construction, precast beams and other components expedite construction. In industrial buildings, precast columns and slabs can meet diverse functional requirements. In short, precast concrete components play a vital role in modern construction.

[0003] In the prior art, precast concrete components need to be flipped over for ease of use. The flipping of precast concrete components is mainly carried out in the following two ways:

[0004] First, the crane flipping method is commonly used for flipping precast concrete parts. Generally, a crawler or truck crane of appropriate tonnage is used, equipped with lifting equipment such as a hook and wire rope. During operation, the precast part is first securely tied with specialized slings or wire ropes. The tying position must be carefully selected based on the shape, size, and center of gravity of the precast part to ensure stability. The crane then slowly lifts the precast part to a certain height above the ground, with the operator closely monitoring the process to ensure a smooth ascent. The crane then rotates the boom or moves the body of the crane to flip the precast part mid-air. The speed and angle must be carefully controlled to avoid loss of control due to excessive inertia. Finally, once the precast part has been flipped to the desired position, the crane slowly descends and places it steadily in the designated location. While this method has certain advantages, it also has several disadvantages. First, it requires high crane selection and operator skills. If the tonnage is not selected correctly, the flipping operation may not be completed safely. Inexperienced operators may make mistakes during the lifting, flipping, and lowering process, causing the precast part to shake, tilt, or even fall, potentially leading to safety accidents. Second, it is subject to site constraints, requiring ample space for crane operation, which can be difficult to implement in narrow locations. In addition, the costs are relatively high, including crane rental fees, operator salaries, and possible equipment maintenance costs. Moreover, during the flipping process, the prefabricated parts may be partially damaged due to improper bundling positions or external forces, affecting their quality and appearance.

[0005] Second, use a turning machine to turn it over. Most existing turning machines are fixed or semi-fixed structures and are fixed in a certain position. In actual use, the precast concrete components need to be moved to that position before the turning operation can be performed. This process not only increases the workload and cost, but also greatly reduces the turning efficiency. Moreover, when the space for the turning machine installation position is limited, it is difficult to adapt to larger precast concrete components and cannot meet their turning requirements. This large limitation restricts the use of turning machines in many actual scenarios, and it cannot flexibly provide efficient turning services for precast concrete components of different sizes, which brings many inconveniences to the construction and use of precast concrete components.

Specifically, the bearing chassis 7 is symmetrically provided with a flip seat 8, and the right-angle frame can rotate with two flip seats 8 at the same time, and the opening of the right-angle frame faces upward, and its rotation plane is perpendicular to the bearing chassis 7. This careful design enables the flipping device to show greater flexibility and convenience in actual use. Whether in different construction sites or facing various complex scenarios, it can meet the flipping needs of precast concrete components, bringing great convenience to the construction operation of precast concrete components.

[0031] In actual use, the turning device of the present application is first conveniently moved to the construction site, where the precast concrete components are to be installed, using a rolling mechanism. Next, the precast concrete component to be turned is hoisted onto a right-angle frame, with one side of the precast concrete component aligned with the first plate frame 3 or the second plate frame 4. The other side of the precast concrete component now becomes the target surface. Subsequently, the hydraulic telescopic rod 13 is activated to cause the right-angle frame to turn until the precast concrete component reaches the desired position. This application successfully achieves the turning of precast concrete components. Compared to traditional crane-based turning methods, this method significantly improves efficiency and reduces costs, while also significantly enhancing stability and preventing damage to the precast concrete components.

The front moving wheel 14 and the two rear moving wheels 15 are both arranged on the bottom side of the carrying platform 1 and are distributed in a triangular shape.

[0033] The front moving wheels 14 are rotatably arranged on the carrying platform 1 , and the front moving wheels 14 are provided with a trailer 2 for adjusting the steering of the front moving wheels 14 or pulling the front moving wheels 14 to move.

[0034] In the above embodiment, the triangular arrangement of the front moving wheels 14 and the two rear moving wheels 15 provides significant structural stability, ensuring stable movement of the present invention.
