Gravity friction brake for high-rise escaping machine

Abstract

The invention relates to fire equipment, belongs to the field of machinery and specifically relates to a gravity friction brake for a high-rise escaping machine. The gravity friction brake comprises a flexible brake strap system and a brake controlling mechanism, wherein the flexible brake strap system is formed by a locating plate, a bolt, a T-shaped plate, a spring washer, a brake steel belt, a an asbestos tape, and the brake controlling mechanism is formed by a support, a pin shaft, a split pin, a swing bolt, an U-shaped connector, a brake handle, a flexible rope, a short pin shaft and a long pin shaft. Escaping people can control the brake controlling mechanism through the flexible rope to adjust brake force of the gravity friction brake. All pin shafts in the brake controlling mechanism are in clearance fit to achieve adjustment of a brake angle. The gravity friction brake has the advantages that the gravity friction brake of the high-rise escaping machine is a flexible brake strap device, so that friction generated by brake force exerted on a braked winding drum through the brake handle can be evenly distributed and is easy to control. Thus, when the gravity friction brake is wholly applied to the high-rise escaping machine, the gravity friction brake is convenient, safe and reliable. In addition, the gravity friction brake is low in cost, suitable for large-scale production and suitable for being popularized and applied.

Description

technical field [0001] The invention relates to fire-fighting equipment, which belongs to the field of machinery, in particular to a gravity friction brake used for high-rise escape machines. Background technique [0002] With the development of society and the acceleration of urban construction, there are more and more high-rise buildings in the city. When people live in high-rise buildings, in case of emergencies, such as fires, earthquakes, etc., how to quickly transfer people to the ground is a must. It is currently the subject of research by many researchers. At present, various high-rise escape machines and escape devices have emerged in the market, but they all have the following defects: they cannot transfer personnel in batches; the transfer speed is too slow; there are operational skills and physical requirements for the transferred personnel. Contents of the invention [0003] The purpose of the present invention is to solve the existing problems, and provide p...
