Problems solved by technology

[0002] At present, most of the braking devices of ordinary high-rise escape or high-rise slow-down devices adopt friction brake structures to control the descending speed of high-rise slow-down devices. Due to the effect of gravity, the high-rise slow-down 2 The acceleration decreases, which brings a great burden to the brake device, and the friction lining wears out quickly, or the friction lining with higher cost and better performance needs to be used, resulting in an increase in the braking cost.

Abstract

The invention belongs to the technical field of high-altitude operation and relates to a high-rise descent control device. The high-rise descent control device comprises a paying off tube, wherein a rotating shaft is arranged in the paying off tube in a penetrating way, a retractable rope is wound and arranged on the rotating shaft, one side of the rotating shaft arranged in the paying off tube is provided with a friction braking device used for braking the rotating shaft, one side outside the paying off tube is provided with a crank handle or a hand-operated wheel connected with the rotating shaft, the lower side of the paying off tube is connected with a seat basket, and the other side of the rotating shaft arranged in the paying off tube is provided with a damping speed reducing device. The high-rise descent control device has the advantages that the gravity and the inertia effect of damping particles are utilized, the damping speed reduction braking effect is good, and the high-rise descent control device is suitable for being used for high-altitude operation or high-rise escaping devices.

Description

technical field [0001] The invention belongs to the technical field of high-altitude operations, in particular to a slow-down device for tall buildings. Background technique [0002] At present, most of the braking devices of ordinary high-rise escape or high-rise slow-down devices adopt friction brake structures to control the descending speed of high-rise slow-down devices. Due to the effect of gravity, the high-rise slow-down 2 The acceleration decreases, which brings a great burden to the brake device, and the friction lining wears out quickly, or it is necessary to use a friction lining with a higher cost and better performance, resulting in an increase in the cost of braking. Contents of the invention [0003] The object of the present invention is to provide a high-rise slow-down device with good damping deceleration effect and easy braking. [0004] The purpose of the present invention is achieved like this: [0005] The high-rise slow-down device includes a pay-...
