Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] see Figure 1-Figure 3 , the high-altitude escape device includes a cable 2 and a speed controller 3, and the speed controller is sleeved on the surface of the cable. The cable 2 is suspended high in the air through the pulley 1, forming two sections that slide up and down, one section is the no-load section, which is socketed in the speed controller 3, and the other section is the load section, which is fixedly connected with the speed controller. The speed controller 3 includes a housing 3.1, which is provided with several pin shafts whose intervals are greater than the diameter of the cable, wherein at least one pin shaft is slidingly provided with a brake pin shaft 7; a section of the cable socketed with the speed controller is at least dislocated The brake pin and the pin above the brake pin.

[0021] The casing 3.1 of the speed controller...

Abstract

A high altitude escape device comprises a mooring rope and a speed controller; wherein the speed controller is arranged on the surface of the mooring rope, the mooring rope is suspended in the sky by a pulley to form two up and down slip sections, one section is a no-load section is sheathed in the speed controller, and the other section is a load section and is fixedly connected with the speed controller; the speed controller comprises a shell and is internally provided with a plurality of pin shafts at intervals more than the diameter of the mooring rope; wherein a braking pin shaft is arranged above or below at least one pin shaft in a sliding way; one section of the mooring rope sheathed with the speed controller winds the baking pin shaft and the pin shafts below or above the brakingpin shaft at least in a dislocation way. In the invention, friction is produced between the mooring rope as well as the pin shaft and the braking pin shaft by dislocation winding of the pin shaft andthe braking pin shaft in the no-load section of the mooring rope and the speed controller, thus achieving the effect of reducing the descent speed of the speed controller. The no-load section of the mooring rope winds the pin shaft of the speed controller in the dislocation way, so that friction is produced between the mooring rope and the pin shaft, thus achieving the aim of reducing the descentspeed of personnel evacuation.

Description

technical field [0001] The invention relates to a high-altitude escape device, which is especially suitable for people on the upper floor of a high-rise building to escape from the stairs and escape from the window or the roof to the ground. A high-altitude escape device adapted to rescue people trapped in high-rise buildings, cliffs, and sightseeing cable car failures, and a method for controlling the descending speed thereof. Background technique [0002] Along with the development of city at present, high-rise building constantly increases, and more and more higher, once run into fire, the personnel in high-rise cannot escape from stairs, be trapped in former housing or be forced to the top floor rooftop. Firefighters on the ground can't go up the stairs to rescue them. They can only rely on the trapped people to rescue themselves. The safest way to go from a tall building to the ground is to use steel wire ropes to transport people to the ground. However, the speed of pe...
