The invention provides a construction hoist with an overhead traction machine. The construction hoist comprises a hoistway, an elevator lifting assembly, a counterweight lifting assembly, a permanent magnet traction machine power assembly, a main track, an auxiliary track, a bearing cross beam, a traction steel rope assembly, a speed reduction assembly and a control system. The permanent magnet traction machine power assembly is arranged on the bearing cross beam, the installation position is limited in the hoistway, and the risk that constructors fall accidentally is eliminated. The elevator lifting assembly and the counterweight lifting assembly are vertically connected through the traction steel rope, the gravity center of the structure is balanced, and the risks of top rushing and overturning existing in a traditional externally-hung elevator are eliminated. Compared with a traditional externally-hung construction hoist, the safety coefficient of the construction environment is remarkably improved.
本发明提供了一种曳引机顶置式施工升降机,包括:井道、电梯升降组件、对重升降组件、永磁曳引机动力组件、主副轨道、承重横梁、牵引钢绳组件、减速组件和控制系统。本发明将永磁曳引机动力组件置于承重横梁之上,安装位置限定于井道内,消除了施工人员意外坠落的风险。采用牵引钢绳垂直连接电梯升降组件和对重升降组件,平衡结构重心,消除了传统外挂式升降机存在的冲顶、倾覆的风险。相对于传统的外挂施工升降机,本发明产品显著提升了施工环境安全系数。
