The invention relates to a hoisting mechanism and a lifting device.The hoisting mechanism comprises a rack, a rope winding assembly, a rope climbing assembly and a traction rope, the rope winding assembly and the rope climbing assembly are both arranged on the rack, one end of the traction rope is sequentially connected with the rope climbing assembly and the rope winding assembly, part of the traction rope is wound around the rope winding assembly, and the rope climbing assembly is configured to be capable of achieving rope climbing through meshing of the traction rope. And the rope winding assembly is used for winding or unwinding the traction rope, the rope winding assembly is configured to be capable of detecting the tensile force of the traction rope located between the rope climbing assembly and the rope winding assembly, and the rope winding assembly adjusts the rope winding or unwinding speed according to the tensile force. The rope winding assembly of the hoisting mechanism can adjust the rope winding speed or the rope unwinding speed by detecting the tensile force of the traction rope so as to be matched with the rope climbing speed of the rope climbing assembly, the rope climbing assembly does not need to wind the traction rope, and therefore the rope climbing assembly can move at a constant speed in the traction direction, and the hoisting mechanism has high safety.
本发明涉及一种卷扬机构及升降装置,其中,卷扬机构包括机架、收绳组件、爬绳组件和牵引绳,收绳组件和爬绳组件均设置在机架上,牵引绳一端依次连接爬绳组件和收绳组件,且部分卷绕在收绳组件上,爬绳组件被配置为能通过咬合牵引绳,以沿牵引绳的牵引方向往复均速移动,收绳组件用于对牵引绳进行收绳或放绳,收绳组件被配置为能检测位于爬绳组件与收绳组件之间的牵引绳的张紧力,收绳组件根据张紧力的大小调整收绳或放绳的速度。该卷扬机构的收绳组件可以通过检测牵引绳的张紧力调节收绳或放绳的速度,以适配爬绳组件的爬绳速度,而该爬绳组件无需卷绕牵引绳,因此爬绳组件可以沿牵引方向匀速移动,以使该卷扬机构具有较高的安全性。
