Description

Technical Field

[0001] This invention relates to the field of steel plate processing technology, specifically to a grating platform steel plate hoisting reference positioning device. Background Technology

[0002] In the construction of steel plate cutting on grating steel platform, the hoisting and precise positioning of steel plates is one of the core processes. At present, the traditional method commonly used in the industry is to rely on manual observation and use tools such as walkie-talkies to direct the crane operator to operate the hook for rough positioning. After the steel plate is suspended above the target grating work position, construction personnel often need to use tools such as crowbars to apply external force at close range to fine-tune and finally complete the placement and alignment of the steel plate.

[0003] Traditional hoisting methods suffer from poor positioning accuracy, relying entirely on human judgment and fine-tuning of the hook. This makes it difficult to quickly and accurately align the steel plate with the designated position below the grating, leading to deviations and requiring repeated adjustments. Furthermore, the operation is inefficient, with each hoisting requiring complex command and communication and repeated fine-tuning, severely slowing down the overall construction progress. Finally, the safety risks are extremely high, as construction personnel must intervene under or near the suspended steel plate, posing significant risks of injury such as crushing or crushing injuries due to operational errors, communication difficulties, or swaying of the steel plate.

[0004] General lifting equipment such as hooks and slings can only perform basic lifting and moving functions. They cannot adapt to the special structure of the grid platform, nor can they achieve automatic guidance and precise positioning of the steel plate before and after hook release.

The tooling limit seat 1 slides and adjusts along the length direction of the moving seat 31 on the guide rail base 2. Rotating the threaded rod 352 causes the threaded rod 352 to rotate within the adjusting block 353, thereby moving the threaded rod 352. The threaded rod 352 adjusts the position of the tooling limit seat 1 through the connecting seat 351. When the tooling limit seat 1 moves, it drives the guide slide rod 356 to move along the guide rail. The surface of the positioning block 355 slides to guide the tooling limit seat 1. The tooling limit seat 1 is adjusted to slide in the width direction of the guide rail base 2 to accommodate steel plates of different sizes. When the steel plate is lowered, its edge will contact the surface of the ramp guide part 101, which can provide effective guidance and limiting function at the moment the steel plate is released. Under its own weight, the steel plate automatically slides into the predetermined position along the ramp guide part 101, which greatly reduces the placement error, ensures the matching of the steel plate with the grid station, and improves the construction quality of installation and cutting.
