Description

Technical Field

[0001] The invention relates to the technical field of steel structure hoisting, and in particular to a hoisting device and method for steel structure processing and transfer. Background Art

[0002] Steel structure plates are one of the important materials used to build steel buildings or structures. These plates are usually made of high-strength steel, have good mechanical properties and durability, can withstand large loads, and are suitable for various industrial and civil construction projects. Steel structure plates mainly include: steel plates, color layer steel plates, corrugated steel plates and composite sandwich panels, etc. When transferring steel structure plates, a lifting device is required to transport the steel plates.

[0003] Publication No. CN220431994U discloses a magnetic lifting device. The application includes a bracket, a main body of the magnetic lifting device, a fixing plate and a permanent magnetic lifter. A card slot 1 is provided on the upper surface of the bracket, a slider is slidably connected to the inner back of the card slot 1 of the bracket, the upper surface of the slider is welded to the lower surface of the main body of the magnetic lifting device, an L-shaped connecting plate is welded to the back of the bracket, a hydraulic cylinder 2 is welded to the inner side wall of the L-shaped connecting plate, and the output end of the hydraulic cylinder 2 is welded to the back of the main body of the magnetic lifting device.

[0004] Although the above-mentioned application and the prior art enable the workers to use the equipment without the need to carry out secondary handling of the workpiece, thereby reducing the labor consumed by the workers when using the equipment, when the above-mentioned application and the prior art are used to hoist the overly long steel structure plate, the two ends of the steel structure plate will be lifted up, causing the two ends of the steel structure plate to be deformed during the excessive transfer, thereby causing damage to the steel structure plate, and when hoisting the two ends of the steel structure plate, the middle part of the steel structure plate will be dented, causing the steel structure plate to be deformed at the least, and causing the steel structure plate to fall off from the permanent magnetic lifter at the worst, thereby causing danger, and in When fixing the two ends of the steel structure plate, it is necessary to first contact the permanent magnetic lifter with the top of the steel structure plate so that the permanent magnetic lifters at both ends can maintain the same distance from the two ends of the steel structure plate. Therefore, during the long movement, the bottom of the permanent magnetic lifter will scratch the impurities on the top of the steel structure plate, which will cause damage to the bottom of the permanent magnetic lifter and affect the service life of the permanent magnetic lifter. If a scraper is set on the surface of the permanent magnetic lifter, it will affect the contact distance between the permanent magnetic lifter and the steel structure plate, so that the permanent magnetic lifter cannot adsorb the steel structure plate well. Therefore, we propose a lifting device and method for steel structure processing and transfer. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a hoisting device and method for steel structure processing and transfer, which has the advantages of over-long hoisting, preventing dents and scratches, etc., and solves the problem that when the over-long steel structure plate is hoisted in the above-mentioned application and the prior art, the two ends of the steel structure plate will be warped, causing the two ends of the steel structure plate to be deformed during the excessive transfer, thereby causing damage to the steel structure plate, and when the two ends of the steel structure plate are hoisted, the middle part of the steel structure plate will be dented, causing the steel structure plate to be deformed at the least, and causing the steel structure plate to fall off from the permanent magnetic lifter at the worst. This may cause danger, and when fixing the two ends of the steel structure plate, the permanent magnetic lifter needs to be contacted with the top of the steel structure plate first, so that the permanent magnetic lifters at both ends can maintain the same distance from the two ends of the steel structure plate. Therefore, the bottom of the permanent magnetic lifter may be scratched with impurities on the top of the steel structure plate during excessive movement, thereby causing damage to the bottom of the permanent magnetic lifter. If a scraper is provided on the surface of the permanent magnetic lifter, the contact distance between the permanent magnetic lifter and the steel structure plate will be affected, so that the permanent magnetic lifter cannot adsorb the steel structure plate well, affecting the service life of the permanent magnetic lifter.
