Abstract

The utility model provides an altitude safe descender which does not need manual control and can descend in stable speed. The altitude safe descender is characterized in that a slow descent device is composed of a rope-winding rotating tray, a rotating wheel, a friction block, a housing, etc. When people descend, a descending rope is pulled out from a rope-winding tray to drive the rope-winding rotating tray and the rotating wheel in the slow descent device to rotate; thus, a friction block inlaid in the rotating wheel can generate the centrifugal force and generate the friction force for the inner circumference of the housing; thereby, the descent speed is automatically adjusted, and the altitude safe descender descends stably. The utility model is suitable for safe descent when the fire occurs in the life and workers of the tall building at the time of escaping and working high above the ground. The descent speed is less than or equal to 2.5 meters per /second.

Description

Altitude safe descender

The utility model relates to the fire-extinguishing and lifesaving technical field, is a kind of improved high-altitude safe drop device.The life that is applicable to middle and high layer building (as hotel, restaurant etc.) and the worker usefulness of taking refuge of when something unexpected happened (as fire), escape, and the usefulness of the safe decline of do during work high above the ground.

Build the urban skyscraper, reduce floor space, but bring new problem simultaneously, in case the high building breaking out of fire, passenger elevator often loses function, fire-fighting stairway also can be often ineffective, people stand incessantly suffocating of dense smoke and burning of raging fire, and for escaping, the route of retreat often is to descend from window and balcony, for this reason, various high-rise building life saving equipment have been developed both at home and abroad.

The high-rise building life saving equipment is answered light and flexible, safe and reliable, and existing type has lifebuoy descending lifeline, lifesaving descent control device, lifesaving road, brucker survival capsule etc., and wherein the method for more employing is that the rescue rope adds descending lifeline.Descending lifeline is the core in the high-rise building life saving equipment, generally all controls decrease speed in case descend too fast with artificial manual operation.But usually cause that people are overstretched mentally during owing to fire, be difficult to correctly control descending lifeline with hand, especially for old person, the artificial casualty accident that causes out of control of easier generation during use.

The purpose of this utility model provides a kind of improved high-altitude personal security drop device, it not only can descend safely and reliably, and it is main because automatic speed governing device is arranged, do not need manual control control decrease speed in the decline process and speed stabilizing decline, the skyscraper automatic speed regulation buoyant apparatus of suitable people's needs is provided.

The utility model is achieved in that by suspender belt, escape waist purse belt, connecting band, wiring dish, decline rope and descending lifeline forms the high-altitude safe drop device, and descending lifeline is made up of housing, runner, brake pad, axle, bearing and wiring rotating disk.

When human body or object descend according to deadweight, be subjected to force of gravity and fall faster and faster, the rope that descends at the same time drives the wiring dish makes coaxial runner also change fast more more, cause that the centrifugal force that is embedded in brake pad intermarginal outside the runner is also big more, it is just big more that thereby centrifugal force produces the frictional force of housing inner periphery, played the speed governing effect, automatically regulate the speed, reach stable and descend at a slow speed.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Accompanying drawing 1 is the composition diagram of the utility model high-altitude safe drop device.

Accompanying drawing 2 is cutaway views of the descending lifeline of the utility model high-altitude safe drop device.

The drawing numbering: (1) is connecting band, and (2) are hook, and (3) are the decline rope, (4) be descending lifeline, (5) are hook, and (6) are ring, (7) be suspender belt, (8) are the escape waist purse belt, and (9) are the wiring dish, (10) be the wiring axle, (11) are housing, and (12) are brake pad, (13) be the wiring rotating disk, (14) are runner, and (15) are bearing, (16) be axle, (17) are cover plate.

Embodiment 1, and the high-altitude safe drop device performance shown in seeing figures.1.and.2 is as follows:

When personnel in the high building in that fire or other are unexpected when taking place, fasten suspender belt (7) and escape waist purse belt (8), two on suspender belt rings (6) are hooked on the hook (5) of descending lifeline (4), again with connecting band (1) on indoor object that can bearing load, around a few Quan ， And hook (2) the hook jail with connecting bands, human body is crossed outside window or outside the balcony then, owing in the descending lifeline centrifugal governor mechanism is arranged, can adjust decrease speed automatically and make human body keep slower speed stabilizing to descend.Decline rope (3) connects from connecting band, in drop device through wiring axle (10) again behind wiring rotating disk (13), go out drop device and enter in the wiring dish (9) that links to each other with the waist purse belt of escaping fixing.The axle (16) of descending lifeline (4) props up in the axis hole of housing (11) and cover plate (17), bearing (15) is contained on the axle journal of axle (16) and in two side end faces of runner (14) centre bore, the wiring rotating disk (13) and the runner (14) of coaxial rotation also are housed in the housing (11), and the brake pad (12) in runner (14) circumferential groove.The decline rope was drafted when human body descended draws from the wiring dish, thereby drive the wiring dial rotation, the runner coaxial with the wiring rotating disk (14) also rotates simultaneously, make the brake pad (12) that is embedded in the runner outer rim have Li Xin Li And that housing (11) inner periphery is produced frictional force, when the human body decrease speed increases because of force of gravity, runner rotating speed and centrifugal friction piece also increase the frictional force of descending lifeline housing, thereby slowed down rotating speed and decrease speed automatically, reached that personnel do not need manual control and speed stabilizing safety descends.Decrease speed≤2.5 meter/second.
