Technical Field

The invention belongs to the field of descent control equipment, and particularly relates to a damping mechanism of a descent control device.

Background

The descent control device is an important tool for emergency escape of residents living in a high-rise building, and is a purely mechanical escape tool which is safe, convenient and fast and does not need a power supply.

The damping mechanism of the descent control device is a core component of the descent control device, and the damping mechanism adopted by the traditional descent control device mainly utilizes the hard friction of the mechanism to realize the deceleration effect. As shown in fig. 5, one of them is to use a centrifugal friction mechanism to generate sliding friction to control the descending speed, but the mechanism has the problems of oil, water and fire resistance, can only work under specific environment, and has a seriously too short service life. Meanwhile, due to friction heat generation in the descending process, the product function of the descent control device is limited, the use scene is limited within thirty meters, namely, the safety of the descent control device is difficult to guarantee for floors above ten floors. As shown in fig. 6, another type of descent control device employs an escapement mechanism, in which an escapement piece is fixed and has no expansion space. The requirement of slow descending on the installation precision of the contact part of the friction points is very high by adopting the escapement mechanism, the mechanism can be blocked if the intersection depth of the two friction points is large, and the friction head can be quickly ground off and loses stability if the intersection depth is small. Therefore, the existing descent control device product cannot be widely and safely applied and has short service life.
