Description

Technical Field

[0001] The utility model belongs to the field of mechanical manufacturing, and in particular relates to a lifting and transporting sling for corrugated plate sheets. Background Art

[0002] During the quay crane manufacturing process, the machine room, as a key location for control equipment, plays a central role in the crane's control system. To ensure the safety and stability of the machine room at high altitude, the production team selected galvanized corrugated sheet metal as the primary material for the machine room walls. Galvanized corrugated sheet metal's excellent corrosion resistance effectively withstands adverse conditions such as humidity and salt spray at high altitudes, ensuring the long-term durability of the machine room walls. Furthermore, its high strength and deformation resistance provide solid structural support for the machine room, maintaining its stability and overall strength even during high-altitude operations.

[0003] To improve welding efficiency and quality while reducing labor and material resources, the corrugated panels of the machine room enclosure utilize advanced laser automated welding technology. This technology welds the entire sheet of corrugated panel in one operation, ensuring weld strength and significantly improving production efficiency. The welded panels undergo a rigorous inspection process. Once verified, they are safely transferred to the machine room frame using specialized lifting equipment, ready for subsequent fabrication.

[0004] Currently, before lifting and transshipment, it is necessary to select suitable lifting points on the corrugated sheet. These lifting points need to be able to withstand the weight and stress generated during the lifting process. Due to its unique wave structure, corrugated sheet has different strength and stiffness distributions. When selecting the appropriate lifting point location, it is necessary to fully consider this structural characteristic and avoid selecting areas with weaker strength. In addition, the weight distribution of corrugated sheet may not be uniform, which requires precise measurement and calculation when selecting the lifting point to ensure that the lifting point can withstand the expected weight and stress. Although the lifting equipment has been mechanized, manual intervention and operation are still required in the selection of lifting points, monitoring and adjustment during the lifting process, etc., which increases the labor intensity and safety risks of the operators.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] This utility model proposes a lifting and transporting sling for corrugated sheet (such as large galvanized corrugated sheet). This lifting and transporting sling is an important device to ensure the quality of the lap welds in the enclosure room and the smooth assembly. The sling uses permanent magnets to complete the lifting and transport of the entire sheet. Through appropriate layout, it can meet the use requirements of the production line. The lifting and transporting sling includes: a lifting beam assembly 1, a magnetic sling 2 and a control assembly 3. Figure 1. The lifting beam assembly 1 includes multiple main beams 11 and multiple first sub-beams 12. The multiple first sub-beams 12 are vertically connected to the multiple main beams 11, and multiple second sub-beams 13 are provided on the multiple main beams 11. The lifting beam assembly 1 serves as the main structure of the sling, bearing the weight of the entire sling and the weight of the corrugated plate during lifting. The lifting beam assembly 1 adopts a steel beam structure with a high rigidity design, and the welded structure is annealed and stress-relieved to ensure that no deformation occurs during the lifting process. The magnetic sling 2 is connected to the second sub-beam 13 and is used to adsorb the corrugated plate sheets. The control assembly 3 is installed above the lifting beam assembly 1. The control assembly includes a control cabinet 31 and a power supply 32. The control cabinet 31 controls the charging and demagnetization of the magnetic sling 2, and the power supply 32 supplies power to the control cabinet 31. The magnetic sling and the control assembly are mounted on the lifting beam assembly 1, and work together to realize the lifting and transportation of the corrugated plate.

[0031] Furthermore, the magnetic lifter 2 is an electro-permanent magnet lifter, which includes a plurality of electro-permanent magnets 21 , and utilizes the magnetic force of the electro-permanent magnets to absorb the corrugated plates, thereby achieving the lifting and transportation of the corrugated plates.

[0032] This sling is required to lift large plates measuring 7×20m. Due to the influence of on-site usage conditions, it is necessary to minimize the weight of the entire sling while ensuring lifting safety. In this embodiment, the sling beam assembly includes: three main beams 11, five first sub-beams 12, and twenty-four second sub-beams 13. The three main beams 11 are parallel to each other, and the five first sub-beams 12 are perpendicularly connected to the three main beams 11, and the five first sub-beams 12 are parallel to each other. The twenty-four second sub-beams 13 are arranged below the three main beams 11. These twenty-four second sub-beams are used to suspend the magnetic sling 2, ensuring that the electropermanent magnets can be evenly distributed on the corrugated plate to achieve stable lifting.

[0033] Because corrugated sheet metal varies widely in size, ranging from a maximum of 7×20m to a minimum of 3×5m, and weighing up to 2 tons, the corrugated sheet metal's wave shape affects its actual adsorption area. Therefore, it is necessary to ensure that the lifter can stably adhere to corrugated sheet metal of varying sizes. In this embodiment, the magnetic lifter 2 includes ninety-six electropermanent magnets 21 arranged in four rows and twenty-four columns. This layout ensures uniform distribution of adsorption force across the entire corrugated sheet metal, avoiding local overload or unstable adsorption. In this embodiment, the electropermanent magnets 21 are thin plate electropermanent magnets, and the appropriate electropermanent magnet coil winding method is selected based on the electromagnet characteristics of the thin sheet metal. Using thin plate electropermanent magnets for lifting reduces the thickness requirements for adsorption on the corrugated sheet metal while ensuring a safe factor, and also reduces safety risks during lifter handling. Preferably, the electropermanent magnets are 750mm×300mm. This size is chosen to provide sufficient adsorption area on the corrugated sheet metal, while also taking into account the wave shape and ensuring that the magnets can cover and stably adhere to at least two wave peaks. The electropermanent magnets have a rated suction force of 25 kg, meaning each magnet provides sufficient force to support the weight of the corrugated sheet during attraction. By adjusting the magnets' charging and demagnetization states, stable attraction and release of the sheet can be achieved. During the lifting process, all magnets work simultaneously, providing sufficient suction force to support the sheet's weight. It should be understood that the electropermanent magnet lifter is designed to be highly flexible and can be adjusted to accommodate changes in sheet size. By increasing or decreasing the number of magnets and adjusting their layout, stable lifting of corrugated sheets of varying sizes can be achieved without changing the lifter or making complex adjustments.

[0034] Furthermore, the control component 3 also includes a power switch, which controls whether the power supply is supplied to the control cabinet 31 .

[0035] Furthermore, the control assembly 3 includes an indicator light that provides feedback on the adsorption status of the magnetic lifter to ensure a safe and stable lifting process. In this embodiment, a flashing green indicator light indicates that magnetization is ready, a solid green indicator light indicates that lifting is ready, and a red indicator light indicates that demagnetization is complete.

[0036] Furthermore, the power source is a battery 32, which supplies power to the control component 3. The battery design allows the device to move with the spreader without the need to drag an additional charging cable.

[0037] The lifting and transporting sling is connected to the lifting equipment through a connecting assembly 4. The connecting assembly 4 includes multiple steel ropes and a lifting lug 41. One end of the multiple steel ropes is fixed on the hanging beam assembly 1, and the other end of the multiple steel ropes is connected to the lifting lug 41. The lifting lug 41 is connected to the lifting equipment.

[0038] The device supports remote control for magnetization and demagnetization settings, and can flexibly adjust the magnetization and demagnetization areas of the permanent magnets according to the length of the plate, achieving more precise and intelligent control, and improving operational flexibility and efficiency. The specific implementation process of the utility model for a lifting and transporting sling for corrugated plate is as follows:

[0039] Step 1: Turn on the power switch of the control cabinet and turn off the ground detection;

[0040] Step 2: Use the remote control to magnetize the lifting device, wait for the indicator light to flash green, and then press the full magnetization button. The lifting device will magnetize the lifting device in response to the signal output by the full magnetization button. When the indicator light is always green, it means that the lifting device is fully magnetized and can be lifted.

[0041] Step 3: Use the demagnetization button on the remote control to perform the demagnetization operation (lock + demagnetization). The lifting and transfer spreader will demagnetize in response to the signal output by the demagnetization button. When the indicator light turns red, it means that the demagnetization is completed.

[0042] The remote control allows for the magnetization and demagnetization of the permanent magnets in zones based on the length of the plate. This process is repeated until the lifter has completed the lifting and transfer of the corrugated plate. The permanent magnet lifter is relatively simple to operate; simply charging and demagnetizing the magnets allows for attachment and release. This greatly simplifies the lifting process, reduces the complexity and time required for manual operation, and improves work efficiency.

[0043] The lifting and transporting sling for corrugated plate of the utility model has the following beneficial effects:

[0044] 1. The lifting and transfer spreader uses batteries, which enables the spreader to move freely without the need to drag the charging cable, greatly improving the convenience and flexibility of operation.

[0045] 2. By using thin-plate electropermanent magnets for lifting, this lifting and transporting spreader reduces the thickness requirements for corrugated sheet adsorption while ensuring sufficient safety factors, effectively reducing potential safety risks during lifting and transport. By rationally distributing electropermanent magnets, this lifting and transporting spreader can lift and transport large sheets of varying sizes, improving operational efficiency.

[0046] 3. The lifting and transferring spreader is equipped with an indicator light, which can intuitively display the adsorption status of the spreader, so that the operator can quickly and accurately understand the working status of the spreader, ensuring the safety and accuracy of the operation.

[0047] The above embodiments are merely further explanations of the present invention and are not intended to limit the present invention in any other manner. The present invention may have many other embodiments. Without departing from the spirit and substance of the present invention, those skilled in the art may make various modifications and variations based on the present invention, and such modifications and variations shall fall within the scope of protection of the present invention.
