Abstract

The utility model relates to a life saving rope for a high building, which relates to the technical field of life saving appliances. The utility model is mainly characterized in that a main shaft (1) passes through a rope box (2) and a gear box (12); a reel (3), a rope stopper (4), and a rope (5) are tightly fixed on the end of the main shaft inside the rope box; the end of the main shaft inside the gear box has gears (7), (8), and (9); another rotating shaft (16) is arranged additionally inside the gear box; the rotating shaft (16) has gears (10), (11); a ratchet pawl (15) is arranged on the body of the gear box; a spring (14) is connected with a ratchet wheel and is used for controlling the rotation of the ratchet wheel. The life saving purpose can be obtained by fixing the life saving rope for a high building on an indoor stable object, hooking a hook (6) on a safety belt (18) worn on the body of a user, jumping out from a window, and then descending slowly down to the ground. The utility model has the characteristics of compact structure, uniform glide speed, and life saving safety.

Description

High-rise life line

The utility model relates to A63H lifesaving appliance technical field.

Along with the development of social science and technology, the urbanization speed of China is also being accelerated year by year.In a large amount of modern cities that occur, skyscraper becomes the important symbol of urban modernization, takes up an area of crowded problem though the use of skyscraper has solved the city, and the skyscraper that stands in great numbers has also caused huge disaster hidden-trouble to modern city.Skyscraper is once catch fire, and personnel not only can not be evacuated effectively in traditional passageway for fire apparatus, and reverse side can be because of being full of a large amount of pernicious gases in fire, forms to be dead passage worthy of the name.(numeral shows according to statistics, and among the fire fatality personnel, the victim who suffocates has accounted for the overwhelming majority) thereby in fire, make the indicator of trapped personnel in the building flee from high-rise quickly and safely is the key that reduces casualties.We can find from experience, and unique quick, the safe outlet of fleeing from of indicator of trapped personnel is the window that building is outwards opened in the building fire.Abroad as just have professor how to utilize the knowledge of thing such as rope in the fire-fighting life-saving training of Japan from the window escape.But this is too specialized to most of people after all, in case of emergency is difficult to use.

The purpose of this utility model is to provide a kind of easy to use, can flee from the high-rise life line at the condition of a disaster scene fast.

For achieving the above object, the utility model is mainly by the following technical solutions:

Form high-rise life line general structure by main shaft, rope case, reel, rope shelves, rope, hook, gear, turning cylinder, ratchet, ratchet, spring, gear-box etc.

With main shaft (1) in rope case (2) and gear-box (12), axle head in the rope case is installed reel (3), rope shelves (4) and rope (5), spindle end in gear-box, gear (7), (8), (9) are installed successively, on the power transmission shaft in gear-box (16), gear (10), (11) are installed successively, ratchet (15) is installed on gear housing, and spring (14) connects and control ratchet (9).

The purpose of this utility model also can reach by other measures:

One end of rope (5) is fixedly connected on the reel (3), and the other end connects hook (6) at the body place of rope case (2).

Gear (7) is to be fixedly mounted on the main shaft (1) with key, and gear (8), (9), (10), (11) connect for rolling.

Ratchet (15) is two claw type formulas, and the one end connects spring (14).

Gear-box (12) is fixed by bolts on the end cap (17), uses bolt to be connected with rope case (2) then.

According to the compact conformation that the utlity model has of technique scheme and measure realization, gliding speed is even, the characteristics that lifesaving is safe and reliable.

Below be the explanation of accompanying drawing of the present utility model and drawing:

Fig. 1 is high-rise life line structure cutaway view.

Fig. 2 is the side view of high-rise life line

Fig. 3 is the another side view of high-rise little living rope

Fig. 4 is ratchet, ratchet, spring connection diagram

Fig. 5 is safety belt and hook schematic diagram

Among the figure: 1, main shaft, 2, the rope case, 3, reel, 4, the rope shelves, 6, hook, 7,8,10,11 gears, 9, gear connects ratchet, 12, gear-box, 13 cappings, 14, spring, 15, ratchet, 16, power transmission shaft, 17, end cap, 18, suspension ring.

The utility model is described in further detail below in conjunction with drawings and Examples:

Make φ 100 rope casees 2 with metal, end cap 17, gear-box 12, main shaft 1 passed through be loaded in rope case, the gear-box, be fastenedly connected reel 3, the two ends connecting strand shelves 4 of reel at the spindle end of rope case, make rope 5 with φ 2mm steel wire rope, the one end is fixed on the reel, and twines on it, and the other end connects hook 6.

The gear-box end of main shaft 1 fixedly mounts gear 7 with key, movable gear 8, the gear 9 installed.On another power transmission shaft 16, the movable successively gear 10,11 of installing, transmission order: gear 7-10-8-11-9.

Gear 9 is the combination wheel of gear and ratchet, and ratchet is subjected to ratchet 15 brakings, and ratchet is a double-claw type, forms escapement by ratchet 9, ratchet 15, spring 14.When ratchet rotates, an end of the tooth inclined-plane of escape wheel compressing escapement pawl, and make it upwards lift the rotation of release escape wheel.Simultaneously, the escapement pawl other end moves downward and finally locks escape wheel again, and with the return spring deformation energy.After This move finishes, the escapement pawl is under the effect of return spring, one end of locking escape wheel is mentioned gradually, make the tooth inclined-plane of escape wheel oppress former locking one end of escapement pawl again, and it is lifted, and discharging escape wheel and rotate, the other end of escapement moves downward simultaneously, lock escape wheel once more, return spring energy storage in the other direction.Alternating movement makes whole system move by certain speed all the time as clock and watch like this, is not subjected to the influence of gravity size.

Gear-box 12 usefulness bolts are connected on the end cap 17, are connected on the rope case 2 with bolt again, form an integral body.

During use, lifesaving appliance is fixed on the indoor solid object by suspension ring 18, hook 6 is caught on the safety belt 19 that is through on the person; Perhaps hook 6 is caught on the indoor solid object, safety belt connects suspension ring and descends slowly from window with human body simultaneously, reaches the purpose of lifesaving.
