Embodiment Construction

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

[0020] See Figure 1-Figure 3 , This high-altitude escape device includes a cable 2 and a speed controller 3. The speed controller is sleeved on the surface of the cable. The cable 2 is suspended high in the air by the pulley 1 to form two sections that slide up and down, one section is an unloaded section, which is sleeved in the speed controller 3, and the other section is a load section, which is fixedly connected to the speed controller. The speed controller 3 includes a housing 3.1, which is provided with a number of pin shafts whose intervals are greater than the diameter of the cable, wherein at least one of the pin shafts is slidably provided with a brake pin 7; a section of the cable sleeved with the speed controller is at least misplaced and bypassed The brake pin shaft and the pin above the brake pin shaft.

[0021] The housing 3.1 of the speed controller 3 is...

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 braking pin 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 and the 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 descent speed of personnel evacuation.

Description

Technical field [0001] The invention relates to a high-altitude escape device, which is especially suitable for upper-floor personnel who cannot escape from stairs and escape from windows or rooftops to the ground from a fire on the lower floors of high-rise buildings. It is adapted to rescue people trapped in high-rise buildings, cliffs, and cable car failures to rescue trapped people and its descending speed control method. Background technique [0002] At present, with the development of the city, high-rise buildings continue to increase, and they are getting higher and higher. Once a fire is encountered, people on the upper floors cannot escape from the stairs, trapped in the original housing or forced to the top roof. Ground firefighters cannot rescue from the stairs. They can only rescue themselves by trapped persons. The safest way from tall buildings to the ground is to use steel wire ropes to transport people to the ground. However, the speed of descent is difficult to c...
