Descent control device

Abstract

The invention provides a descent control device which comprises a cotton rope winding drum, a power generator, a descent control motor, a cotton rope winding drum speed reducing mechanism, a speed sensor, a manned device and a control device, wherein the cotton rope winding drum is sleeved on a rope shaft, the rope shaft is fixed on a stand, a cotton rope is wound on a drum body of the cotton rope winding drum, one end of the cotton rope is fixed on the drum body and the other end is led out, a friction disk is arranged on the cotton rope winding drum; the manned device is connected with the cotton rope; an electricity-generating rotating element is arranged on the power generator, the cotton rope is wound on the electricity-generating rotating element of the power generator; and the descent control motor is fixed on the stand, and a power supply input end of the descent control motor is connected with an electric energy output part of the power generator. The descent control device drives a clamping mechanism through the motor to rub a wear-resisting shaft disk, therefore, the speed of dropping the cotton rope is reduced to ensure that the descent control device can be dropped at constant speed basically and is rapid and safe as well as is convenient for elders and children.

Description

technical field [0001] The invention relates to a descending device, in particular to a descending device which is easy to operate, safe and reliable. Background technique [0002] In accident sites such as fires and earthquakes, landing mechanisms are needed to rescue people on high-rise buildings. The landing mechanisms can be installed on building windows, balconies or flat roofs of buildings, or on elevating fire trucks. The trapped people on high-rise buildings were quickly rescued. [0003] Some of the lowering mechanisms in the prior art have complex structures and require a power supply in use. In the event of an accident, high-rise buildings are usually powered off, and it is impractical to use a landing mechanism with a power supply; a landing mechanism with a complex structure is very prone to failure if it is placed for a long time. Some landing mechanisms are complicated to use and operate, and are often inconvenient to use for non-professionals. When a dange...

Problems solved by technology

[0003] The lowering mechanism in the prior art has a relatively complicated structure and needs a power supply in use

In the event of an accident, high-rise buildings are usually powered off, and the landing mechanism using a power supply is not practical; the landing mechanism with a complex structure is very prone to failure if it is placed for a long time

Some landing mechanisms are complicated to use and are often inconvenient for non-professionals

When a dangerous situation occurs, rescuers are often unable to go to the top and come to the side of the rescued person. In an emergency, people in distress, especially the elderly or children, are prone to panic. Complicated operations will slow down the speed of escape. If the operation is wrong, it will happen new danger

Furthermore, the existing descending mechanism cannot automatically adjust the descending speed, and the safety and comfort during the descending process are relatively poor.
