Reciprocating type portable descent control device

Abstract

The invention relates to a reciprocating type portable descent control device, wherein, a friction wheel rope pulley (3), two small rope pulleys (12), two big rope pulleys (11) and a cam (4) are arranged between a main plate (1) and a side plate (2); the friction wheel rope pulley and the cam are oppositely arranged from top to bottom; the big rope pulleys are respectively arranged at the left side and the right side of the cam; the small rope pulleys are respectively arranged at the left side and the right side above the cam; a big gear (6) is arranged at the other end of a cam shaft; a small gear (8), a friction disk (10) and a flywheel (9) are sequentially arranged at the other end of the rope pulley shaft of the friction wheel rope pulley; the big gear and the small gear are meshed; and a friction flake (7) is arranged between the outer circumference of the flywheel and the inner circumference of the friction disk. In the invention, the cam is adopted and deflects to extrude ropes moving mutually to generate friction resistance for braking to achieve the purpose of reducing the speed, thus the speed is slower, and the safety is better; and the flywheel is used for driving and controlling the cam to deflect to extrude the ropes, and the force of the cam for extruding the ropes is adjusted, thus the braking performance is stable and reliable. The reciprocating type portable descent control device can be carried conveniently and operated simply, is suitable for self-rescue when a user encounters fire in a high building or danger in the field, and can be arranged on a fire engine or matched with an aerial ladder of the fire engine.

Description

technical field [0001] The invention relates to equipment for emergency escape from high-altitude high-rise buildings, in particular to a safe and reliable reciprocating portable descending device. It can be applied to escape from high-altitude platforms, hotels, hotels, apartments, office buildings, schools, residences and other high-rise buildings. It can be equipped with fire fighting vehicles or used in conjunction with fire truck ladders for rescue. It can also be used for outdoor mountaineering and exploration. , deep wells, high-altitude tourist ropeways and other places to implement downhill rescue for people in distress. Background technique [0002] With the development of society and the continuous improvement of modernization, and the continuous acceleration of urbanization, high-rise buildings have sprung up like mushrooms after rain. Subsequently, when a fire, an earthquake or other dangerous situations take place, the safety of people in high-rise buildings b...

Problems solved by technology

Therefore, limited by its deceleration principle, the strength requirements for each component are relatively high, resulting in a complex structure and a large overall product size (length 225mm*width 154mm*thickness 35mm, weight about 3kg), so the cost is also high

[0007] (2) There are unsafe factors

The torque transmitted between the rope and the rope wheel is relatively large. In this case, the rope is ea...
