Technical Field

[0001] This utility model relates to the technical field of wind power flange production equipment, specifically a heavy-duty ring top-type device. Background Technology

[0002] With the rapid development of the global wind power industry, the single-unit capacity of wind turbine generators is constantly increasing, which places higher demands on the size and load-bearing capacity of wind turbine flanges. Traditional 630-ton-class wind turbine flange top-type equipment is gradually revealing numerous problems when facing the production demands of large-size, high-strength flanges. On the one hand, its processing capacity is insufficient to meet the forming requirements of large-size flanges. Its limited worktable size and top-type stroke make it difficult to clamp and process larger flanges, limiting the equipment's application range. On the other hand, its structural strength is limited. Under heavy load conditions, the frame is prone to deformation and stress concentration, leading to unstable equipment operation, affecting the processing accuracy and quality of flanges, and making it difficult to guarantee the efficient and high-quality production of large-size wind turbine flanges, thus failing to meet the ever-increasing production needs of the current wind power industry.

[0012] Preferably, two tank lifting lugs are respectively provided at the top of the two side walls of the hydraulic tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Significantly improved processing capacity: This utility model increases the area of ​​the worktable, which can accommodate the clamping and processing of larger flanges, effectively solving the problem that traditional equipment cannot process large flanges due to insufficient worktable size; at the same time, it increases the top stroke, which can meet the forming requirements of deeper flanges, further improving the processing capacity of the equipment.

[0015] 2. Significantly enhanced structural strength: The frame is welded from high-strength alloy steel, and its stress distribution is simulated using finite element analysis technology.

[0017] 4. Power and System Performance Optimization: Compared to the original single-motor or lower-power motor configuration of the 630-ton equipment, the dual-motor configuration provides greater power, increases the output flow and pressure of the hydraulic pump, meets the higher power requirements of the 1000-ton top-mounted machine, ensures stable operation under heavy loads, and provides strong power support for the efficient operation of the equipment; the hydraulic pipelines are arranged in a relatively neat and orderly manner, and have been redesigned; the reasonable pipeline layout reduces hydraulic oil flow resistance, reduces pressure loss, improves system efficiency, and also facilitates maintenance and repair, reducing equipment failures caused by pipeline problems, and improving the reliability and operating efficiency of the equipment;

[0018] In summary, this utility model has significantly improved processing capabilities, structural strength, processing accuracy, power and system performance, as well as heat dissipation and maintenance performance. It can not only meet the current production needs of large-size wind turbine flanges, but also provide reliable equipment support for the future development of the wind power industry towards larger single-unit capacity. It has important practical value and broad market application prospects. Attached Figure Description
