The invention provides a novel construction hoist transmission mechanism, and relates to the technical field of hoist transmission mechanisms. Comprising a lifting main body, threaded rods are fixedly and rotationally matched with the two sides and the two ends of the interior of the lifting main body, rotating blocks are rotationally matched with the two ends of the threaded rods, the rotating blocks are fixedly connected with the lifting main body, threaded blocks are in threaded connection with the lower portions of the middles of the threaded rods, and a lifting plate is fixedly connected between the threaded blocks; a first gear is fixedly connected to the bottom between the threaded rods at one end, a second gear is fixedly connected to the bottom between the threaded rods at the other end, and rack conveying belts are engaged with the exteriors of the first gear and the second gear. Extension starting is achieved through an electric telescopic rod 6, a supporting rod 604 is pushed by pushing a rotating shaft 601, expansion operation is achieved, locking operation is achieved through meshing of a tooth block 605 and a rack conveying belt 4, the situation that a threaded rod 2 conducts trace autorotation, danger is caused is prevented, and auxiliary locking operation can be achieved.
本发明提供一种新型施工升降机传动机构,涉及升降机传动机构技术领域。包括升降主体,所述升降主体的内部两侧且两端均固定转动配合有螺纹杆,所述螺纹杆的两端转动配合有转动块,且转动块和升降主体固定连接,所述螺纹杆的中部下方螺纹连接有螺纹块,所述螺纹块之间固定连接有升降板;一端所述螺纹杆之间底部固定连接有第一齿轮,另一端所述螺纹杆之间底部固定连接有第二齿轮,所述第一齿轮和第二齿轮的外部均啮合有齿条传送带。通过电动伸缩杆6实现延伸启动,通过推动转轴601实现将支撑杆604推动,达到扩张操作,通过齿块605与齿条传送带4啮合,实现锁紧操作,防止螺纹杆2发生微量自转,造成危险发生,能够实现辅助锁紧操作。
