Dynamic positioning linkage device

The invention relates to a dynamic positioning linkage device, in particular to a linkage device which is arranged between a cabinet body and a cabinet door of hub control equipment in a variable-frequency intelligent control system for 2MW direct-drive wind power generation. According to the existing cabinet door positioning linkage device of the hub control equipment, the cabinet door cannot be opened conveniently or locked automatically, and is easy to loose and poor in reliability. The invention provides the dynamic positioning linkage device, which comprises a limiting guide rail (1), a connecting rod (8), a rotating shaft (12), a connecting rod seat (13), and a supporting plate (14), wherein the connecting rod seat (13) fixed on the supporting plate (14); the limiting guide rail (1) is fixed on the cabinet door (5), the limiting guide rail (1) comprises a clamp groove (3) and a limiting clamp groove (4), one end of the connecting rod (8) is connected with the clamp groove (3) of the limiting guide rail (1), can slide in the clamp groove (3), and can slide to the limiting clamp groove (4), the other end of the connecting rod (8) is connected with the connecting rod seat (13), the rotating shaft (12) first penetrates through the connecting rod seat (13) and then penetrates through the connecting rod (8), and the rotating shaft (12) is rotatably connected with the connecting rod seat (13) and the connecting rod (8). The dynamic positioning linkage device provided by the invention is simple in structure, and the reliability and safety of the linkage between the cabinet body and the cabinet door of the hub control equipment are improved.
