lifesaving descent device

Abstract

The invention discloses a life-saving descent control device, which comprises a left shell and a right shell, wherein the right end face of the left shell is provided with a disc-shaped left circular cavity; a left counter bore used for installing a bearing is at the central position of the left shell, which is located on the left circular cavity; three planetary gear mounting shafts are arranged in the left circular cavity; the left ends of the three planetary gear mounting shafts are connected with the left shell into a whole; the outer edge of the right end of the left shell is provided with a left flange; the left end face of the right shell is provided with a disc-shaped right circular cavity; a right counter bore used for installing the bearing is arranged at the central position of the right shell, which is located on the right circular cavity; the outer edge of the right end of the right shell is provided with a right flange; the left end face of the right flange and the right end face of the left flange are pasted; a placement cavity is arranged between the right flange and the left flange; and the placement cavity is communicated with the outside through two steel wire rope perforations. The invention aims to provide the life-saving descent control device which is small in size, high in strength and safe and reliable in performance.

Description

technical field [0001] The invention relates to a lifesaving slow descent device. Background technique [0002] The life-saving slow-descent device is a device that allows people to directly drop from the window or roof of a high-rise building in the event of a fire or other disasters. Patent No. 201120100458.6, the invention patent of the invention name "reciprocating life-saving slow-down device", discloses such a life-saving slow-down device. Since the life-saving slow-descent device is a life-saving device for personal use, it is required that its weight and volume should not be too large. During the process of sliding down from the window or roof of a high-rise building, the descending speed should be reasonable and even, which involves multiple components. If the design of its structural size is unreasonable, it will often cause the descending speed of the life-saving slow-descent device to be either too fast or too slow, and even endanger the life safety of the user ...

Since the life-saving slow-descent device is a life-saving device for personal use, it is required that its weight and volume should not be too large. During the process of sliding down from the window or roof of a high-rise building, the descending speed should be reasonable and even, which involves multiple components. If the design of its structural size is not reasonable, it will often cause the descending speed of the life-saving slow-descent device to be either too fast or too slow, and even endanger the life safety of the user in severe cases.
