Abstract

The invention discloses a descent control device with simple structure and higher reliability. The descent control device comprises a shell, a rope sheave and a braking rotary table, wherein the rope sheave and the braking rotary table are installed inside the shell through a shaft; the shaft is fixed inside the shell; the braking rotary table is provided with a friction block; the friction block is installed in a sliding chute of the braking rotary table; a friction wall is located inside the shell and corresponds to the friction block; a main body bottom plate with a through hole at the center is fixed inside the shell and located between the rope sheave and the braking rotary table; one or a plurality of satellite gears are installed on one side, which is close to the rope sheave, of the main body bottom plate; the satellite gears are meshed with an inner gear; the inner gear is fixed with the rope sheave; and an outer gear is fixed on the axial line of one side, which is close to the main body bottom plate, of the braking rotary table, passes through the through hole at the center of the main body bottom plate and is meshed with the satellite gears. The descent control device disclosed by the invention has the advantages of simple and compact structure and good stability and reliability, and is convenient to install and use.

Description

technical field [0001] The invention relates to a safety rescue device, in particular to a descending device used for high-rise escape. Background technique [0002] The descending device is composed of hooks or rings, slings, ropes and speed control, etc. It is a safety rescue device that allows people to descend slowly along the ropes. It can be installed on building windows, balconies or flat roofs of buildings with special installation equipment, and can also be installed on elevating fire trucks to rescue victims in high-rise buildings on fire. The slow descending device is suitable for high-rise escape. When working, the slow descending rope drives the planetary gear reduction mechanism in the main engine to run and friction with the friction block in the friction hub to ensure the safety of the user and slowly descend to the ground. However, most of the descending devices in the prior art are complex in structure, not compact, large in volume, heavy in weight, and in...
