The turnover lifting device in the aerated block production line is a crucial supporting equipment in the aerated concrete production process, primarily used for demolding and lifting the green bodies. Below is a detailed introduction to the turnover lifting device:
Working Principle
The turnover lifting device is typically paired with a double-beam double-hook crane. Its operation involves lifting the green body (with mold and baseplate), rotating the mold frame 90 degrees through the turnover mechanism, automatically opening the mold frame with the manipulator of the lifting device to demold, and finally placing the green body along with the side panels vertically onto the cutting trolley for subsequent cutting processes.
Types and Structures
The turnover lifting devices come in two forms: movable and integral. Among them, the air-turnover lifting device employs a hydraulic thruster structure, enabling the four hooks to automatically open and close, adapting to various sizes and weights of green bodies. Additionally, the double-layer hollow design of the side panels serves as insulation. The inner side panels are made of 8mm thick steel plates welded together to enhance rigidity and prevent deformation, thereby extending the service life.
Usage Precautions
Load Limit: Operate strictly within the specified load capacity, never exceeding the rated lifting weight.
Smooth Operation: Lift smoothly to avoid collisions with other equipment that may cause deformation.
Maintenance: Regularly maintain the steel wire ropes on the lifting device, applying lubricant oil or grease, especially at bends. Inspect the main load-bearing components such as components, lifting rings, rotary locks, ear plates, and shackles at least every three months for cracks and severe deformation.
Safety Checks: Frequently inspect the indicator markings on the indicator plate of the turnover lifting device and promptly repair any paint peeling.
Detailed Introduction to the Turnover and Bottom Skin Removal Section
The turnover and bottom skin removal section is a crucial stage in the aerated block production line, primarily responsible for automatically turning over the green body and removing the bottom waste after cutting, facilitating subsequent processes.
Working Principle
The turnover and bottom skin removal machine utilizes mechanical or hydraulic drive mechanisms to rotate the workbench and green body together, typically by 90 degrees. During the rotation, the bottom waste automatically falls off due to gravity. Afterward, the machine resets the green body for subsequent handling, curing, and other processes.
Key Technologies
Turnover Control System: Achieves precise turning of the brick green bodies through servo motors and precision transmission mechanisms, ensuring stability and safety during the turnover process to prevent damage to the green bodies.
Cutting Technology: Employs high-speed rotating diamond blades or other wear-resistant cutting tools to efficiently remove the bottom skin, ensuring neat cuts and minimal loss to the brick body.
Automated Detection and Adjustment: Utilizes photoelectric sensors and intelligent algorithms to monitor the thickness of the green bodies and the bottom skin removal in real-time, automatically adjusting the peeling depth for dynamic and precise bottom skin removal.
Applications and Advantages
Widely applied in aerated block production lines, the turnover and bottom skin removal section can be integrated with cutting machines, curing kilns, and other equipment to form a complete production line or used independently for turning over and bottom skin removal of green bodies. This section facilitates more convenient and efficient waste removal during the production process, enhancing product quality and output. Additionally, it features eco-friendly designs, aligning with the green development needs of the modern building materials industry.
In conclusion, the turnover lifting device and the turnover and bottom skin removal section in the aerated block production line are vital links ensuring smooth production processes, improving product quality, and boosting output. Continuous optimization of these equipment's performance and technologies can further enhance the overall efficiency and competitiveness of the aerated block production line.
