Abstract

The utility model relates to a fireproof cableway, which is used for life saving on building fire sites. The fireproof cableway is mainly composed of frame boards, a main shaft, planet gears, a hollow shaft, steel cables, a brake mechanism and a handle. The main shaft penetrates through the centers of two frame boards; one end is connected with an input end of the planet gear, and the other end is provided with the brake mechanism and is connected with the handle; the hollow shaft is sheathed on the main shaft; one end is connected with the output end of the planet gear, and the other end is connected with the brake mechanism; the steel cable is wound on the hollow shaft. Suspension rings of the frame board are fixed near a window, and evacuated persons are fixed to hooks of the steel cable; a rotation handle sends the evacuated person to the ground to carry out buddy aids, the hook can also be fixed near the window, and the people fixed to the suspension ring can carry out self aids.

Description

Fireproof cableway

The utility model belongs to machinery manufacturing technology field, is a kind of brucker survival capsule that is used for the scene of fire.

At present, building fire happens occasionally, and evacuates very difficulty of scene of fire personnel, especially high-rise, when lower floor's breaking out of fire, top men are difficult for withdrawing from escape way, have only by window to descend, generally be to adopt rope to glide, but use difficulty for old children and patient to ground.

The purpose of this utility model be to provide a kind of easy to use, performance is safe and reliable, can save oneself, again the fireproof cableway that can rescue mutually.

Solution of the present utility model is by frame plate, main shaft, planetary gear, hollow shaft, steel wire rope, arrestment mechanism and handle are formed fireproof cableway, frame plate is two, constitute framework by bolted, main shaft passes the center of frame plate, one end connects planetary gear and goes into end, the other end is equipped with arrestment mechanism, on the main shaft between two frame plates, be with hollow shaft, be wound with steel wire rope on the hollow shaft, the connection of hollow shaft one end is planetary to go out to hold, the other end connects arrestment mechanism, arrestment mechanism is by pedestal, seat, ratchet, friction plate, little axle and ratchet constitute, base sleeve is on main shaft, hollow shaft connects pedestal, cover for seat on main shaft, seat there is internal thread, the main shaft correspondence has external screw thread to the seat place, being with nut on the main shaft in the seat outside, be inserted with split pin on the main shaft, between a pedestal and the seat ratchet is housed, between ratchet and the pedestal, between a ratchet and the seat friction plate is arranged respectively, little axle is fixed on the frame plate lateral surface, is equiped with ratchet on the little axle, the top of ratchet is in the tooth of ratchet, seat is connected handle, on the framework that frame plate and bolt constitute suspension ring are housed, hook is housed on the steel wire rope.During use suspension ring are fixed near the window, the personnel that withdraw are fixed on the hook, and owing to body weight, tension should make hollow shaft rotate around the steel wire rope on the hollow shaft after the personnel of withdrawing were sent outside window, thereby drive pedestal, ratchet rotation.Owing to there is ratchet to be stuck in the tooth of ratchet, ratchet can not rotate, friction plate stops pedestal and hollow shaft to rotate, personnel on the hook can not fall by deadweight, this moment the salvor rotary handle, the drive main shaft rotates, and main shaft drives hollow shaft by planetary gear and rotates, and the release steel wire rope will be withdrawn personnel and deliver to ground.And then the reverse rotation handle, this moment, ratchet did not stop ratchet to rotate, and steel wire rope can be regained, and was rewound on the hollow shaft.Hook is fixed near the window, and the people is fixed on the suspension ring, can save oneself.

The utility model can be rescued mutually, can save oneself again, and is easy and simple to handle, serviceability is safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified:
