The invention relates to the technical field of pulley load hoisting, in particular to a crane pulley. Comprising a U-shaped tackle support, two universal shafts a facing downwards are installed on the lower end face of a top plate of the tackle support, a roller support is arranged below each universal shaft a, and a roller a is arranged in each roller support; a universal shaft b facing upwards is arranged on a bottom plate of the tackle support, an L-shaped driving motor support is fixed to the universal shaft b, a driving motor is fixed to the outer side of the driving motor support, an output shaft of the driving motor penetrates through the driving motor support to be connected with a roller b on the inner side, the roller b is a toothed roller, and the driving motor is fixed to the bottom plate of the tackle support. A lifting motor is fixed below a bottom plate of the pulley bracket; due to the three-roller design of the inverted isosceles triangle, the machine runs more stably; the upper clamping pulley and the lower meshing pulley are matched with the track, so that the driving precision is ensured, the running stability can be further ensured, and meanwhile, the device can adapt to a linear or bent track.
本发明涉及滑车载荷吊装技术领域,尤其涉及一种起重机滑车;包括“匚”字型的滑车支架,所述滑车支架顶板的下端面安装有两个方向朝下万向轴a,每个万向轴a下方均设置有滚轮支架且滚轮支架中设置滚轮a;所述滑车支架的底板上设置有一个方向朝上的万向轴b,万向轴b上固定有“L”型的驱动电机支架,所述驱动电机支架外侧固定有驱动电机,驱动电机的输出轴穿过驱动电机支架与内侧的滚轮b相连接,滚轮b为有齿滚轮,所述滑车支架的底板下固定有提升电机;倒等腰三角形的三滚轮设计使本机运行更稳定;上卡接与下啮合的滑车、轨道配合形式在保证了驱动精度的同时还能进一步保证运行平稳性,同时可适应于直线或弯角轨道。
