Slow descending device

Abstract

The invention discloses a slow descending device, more particularly relates to a single-way type slow descending device which can be used for descending multiple persons at a time and belongs to the field of high-rise rescue. Two defects exist in an existing slow descending device, one defect is that the work principle of the slow descending device determines that the slow descending device can beonly used by one person once at the same time, and efficiency is low; and the other defect is that when a fire happens, if multiple persons use multiple sets of slow descending devices, the lower ends of ropes are likely to be twisted and entangled together, and normal implementation of the function is hindered. By means of the slow descending device, a rack is used for limiting the distance of rotating engagement, the falling energy is transmitted to an energy consumption mechanism, a whole composed of the rack, the energy consumption mechanism and a transmission mechanism can be engaged with a path to slide on the designated path, and therefore the function of conducting descending along the designated path is achieved. A single descending path is adopted in the structure, and the problems of twisting and entangling of the ropes in traditional design are solved. A structure capable of clamping the path is designed on the rack of the structure, multiple pieces of equipment can be clamped at the same time on the path, and the purpose of descending multiple persons at the same time is achieved.

Description

technical field [0001] The invention relates to a slow-descent device, more specifically, to a single-path slow-descent device capable of slow-downing multiple people at one time, and belongs to the field of high-rise rescue. Background technique [0002] With the advancement of the times and the development of technology, more and more people have moved into high-rise residential areas. High-rise buildings are a double-edged sword. On the one hand, they save scarce land resources. It has the characteristics of fast fire spread and slow evacuation of personnel. The Chinese utility model patent with the patent number CN207356383U discloses "a high-rise escape slow descender". The inner gear ring, the planetary gear and the sun gear are connected by transmission, the rope drives the cylinder to rotate, and the central shaft is driven by the inner gear ring-planetary gear-sun gear, and the rope drives the cylinder And the inner gear ring rotates once, and the planetary gear a...
