A maritime crane rotation limiting device comprises a mounting base, a mounting support, a first limiting support, a second limiting support, a limiting gear and a limiting switch. The mounting bracket is connected with the turntable large bottom plate through a mounting seat; the first limiting bracket and the second limiting bracket are respectively connected to the upper and lower parts of one side of the mounting bracket; the limiting gear is located between the first limiting support and the second limiting support and comprises a gear disc and a gear ring, the axis of the gear disc is located between the first limiting support and the second limiting support, and a part of the gear ring is located between the first limiting support and the second limiting support. The other part of the tooth enclosure is positioned outside the first limiting bracket and the second limiting bracket, and the tooth enclosure is meshed with the slewing bearing; the limiting switch is connected with the first limiting support or the second limiting support, and a linkage shaft of the limiting switch penetrates through the first limiting support or the second limiting support to be connected with the limiting gear. Therefore, the design not only can rotate and limit, but also is convenient to install and debug.

    一种海事起重机回转限位装置,包括安装座、安装支架、第一限位支架、第二限位支架、限位齿轮与限位开关;安装支架通过安装座与转台大底板相连;第一限位支架、第二限位支架分别连接于安装支架的一侧上下部;限位齿轮位于第一限位支架、第二限位器支架之间,限位齿轮包括齿轮盘及齿围,齿轮盘的轴心位于第一限位支架、第二限位器支架之间,齿围的一部分位于第一限位支架、第二限位器支架之间,齿围的另一部分位于第一限位支架、第二限位器支架的外部,齿围与回转支承相互啮合;限位开关与第一限位支架或第二限位器支架连接,限位开关的联动轴贯穿第一限位支架或第二限位器支架与限位齿轮相连;因此,本设计不仅可以回转限位,而且安装调试方便。
