Abstract

The invention relates to the technical field of escape knapsack slow descent, in particular to a tower crane emergency escape self-rescue knapsack type slow descent device and an application method thereof. The device comprises a knapsack body, wherein a tightening component is arranged at the rear end of the knapsack body; a hanging component is arranged at the upper end of the knapsack body; a winch is arranged at the lower end in the knapsack body; a slow descent component is arranged at the right end of the winch; a locking component is arranged at the right end of the winch; the tightening component comprises straps; and the two straps are of a bilateral symmetry structure. By using the slow descent component and the locking component, slow descent and rapid locking of the knapsack body are facilitated, a push rod of an emergency stop component is inserted into a positioning hole in a matched mode, the use controllability is improved, different descent speeds are provided for different users, adjustment is convenient and rapid, the good slow descent effect is improved, when an accident occurs or slow descent fails, locking can be conducted in time, secondary accidents are avoided, life safety of the user is protected, safety and reliability are remarkably improved, and the use effect is good.
