The invention belongs to the field of flagpole design, production, installation and construction, and particularly relates to a lifting driving mechanism and device. The lifting driving mechanism comprises a hollow pole body, a winch is arranged at the bottom of the hollow pole body, a first cable body is connected to the winch, the free end of the first cable body penetrates into the top of the hollow pole body from bottom to top, and the free end bypasses a fixed pulley arranged at the top of the hollow rod body and is connected with a hanging tool; and a second cable body is further arranged in the hollow rod body, magnetic attraction units are arranged on at least part of the section of the second cable body at intervals, the part, located in the hollow rod body, of the first cable body is adjacent to the section, provided with the magnetic attraction units, of the second cable body, the first cable body is made of ferromagnetic materials, and a lower guide wheel is in transmission connection with the winch. According to the lifting driving mechanism, part of power of the winch is distributed to the second cable body, the first cable body is attracted through the magnetic attraction unit on the second cable body, then the first cable body is pulled to move upwards through rotation of the second cable body, the gravity of the first cable body is well overcome, and it is ensured that the hanging tool can move downwards stably.
本发明属于旗杆设计生产及安装建造领域,具体涉及一种升降驱动机构及装置,包括空心杆体,空心杆体底部设有绞车,绞车上连接有第一索体,第一索体的自由端从空心杆体内部自下而上穿插至空心杆体顶部,该自由端绕过空心杆体顶部设置的定滑轮与一挂具连接;空心杆体内部还设有第二索体,第二索体的至少部分区段上间隔设置有磁吸单元,第一索体位于空心杆体内的部分与第二索体上装有磁吸单元的区段邻近布置且第一索体由铁磁性材料制成,下导轮与绞车传动连接。本发明将绞车的一部分动力分配给第二索体,利用第二索体上的磁吸单元吸住第一索体,然后利用第二索体的回转来牵引第一索体上行,很好的克服了第一索体自身的重力,确保挂具能够稳定下行。
