Abstract

The utility model relates to a projecting type high-altitude rescuing safety hook, and a projectile body is composed of a projectile head, a rope collecting descent control device and a powder barrel, wherein the projectile head is provided with a probing needle and a hook and is connected with the rope collecting descent control device in the extruding way. The powder barrel is arranged in a projecting barrel. The projecting type high-altitude rescuing safety hook can cause one end of a rope to be injected on a needed high building through the projectile body, the hook gripes a fixed object, and the other end of the rope is left on the ground. The projecting type high-altitude rescuing safety hook achieves the purposes of accurately, rapidly and safely rescuing and saving the labor and is suitable for the needs of the work, such as reconnaissance, dogging work, rescue, etc.

Description

Emission-type height rescue safety door hook

The utility model relates to a kind of height rescue safety apparatus, particularly the evacuation escape personnel's who uses during the high-rise breaking out of fire safety door hook.

Along with developing rapidly of building industry, skyscraper is on the increase, and makes the city more and more bustlinier, beautiful.But the rescue action that is used for the skyscraper breaking out of fire still is with the old way of low-rise building, because the skyscraper personnel evacuate difficulty naturally, it is pressed for time, so the phenomenon of getting injured by a fall, burning often takes place.

The purpose of this utility model is: a kind of emission-type height rescue safety door hook is provided, when solution is caused danger to skyscraper, can realizes rapid, accurate, safe emergency relief.

The technical solution of the utility model is: a kind of emission-type height rescue safety door hook, have body and launching tube, front end has bullet on the body, there is grain the rear end, and this grain is contained in the launching tube front portion, it is characterized in that: the bullet front end is equipped with breaking needle, the bullet side is hinged with hook, rope collection slow drop device two ends and bullet, grain are connected respectively, are contained in the rope in the rope collection slow drop device, and its two ends and bullet, launching tube are connected respectively.

Launching tube in the present technique adopts the prior art of 40mm rocket-launching battery, the grain that is contained in the launching tube front portion is corresponding with the percussion lock on the launching tube, fuse on the grain is relative with percussion lock in the percussion lock, the characteristics of present technique are, hook and rope are contained on the body, and and body be launched into the height rescue place together, hook is caught fixed object, as window frame, perhaps people are fixed on it on the firm object, are connected in the rope on the body, on the launching tube of its other end stand-down, people get on or get off along rope, realize rescue, the purpose of escaping danger.

Because the utility model with fire-fighting and rescue hook and ordnance technology, has the control missilery to combine, and adopts emitter to deliver to skyscraper by body with the hook of rope, thereby realizes height rescue, and is accurate, rapid, safe, laborsaving.

Below in conjunction with drawings and Examples present technique is described further.

Fig. 1 is the structural representation of the utility model emission-type height rescue safety door hook.

Fig. 2 is the A-A view of the utility model Fig. 1.

Fig. 3 is the B-B view of the utility model Fig. 1.

Fig. 4 is the C-C view of the utility model Fig. 1.

Among the figure, body is by the bullet (3) of front end, the descending lifeline at middle part (6), collection rope roll (8), the grain of afterbody (25) constitutes, wherein, between bullet and the descending lifeline mutually extruding connect, thread forms is connected descending lifeline with collecting between rope roll, the grain successively.Front end has breaking needle (1) on the bullet, it can be under forward momentum, puncture the frivolous barrier in the place ahead, the side of bullet, be hinged with hook (5), be used to catch fixture, the hook front is spacing by bullet, the grain (25) of spring (4) afterbody is housed between hook back and the body, its cylindrical shell by interior pipe (11) and outer tube (24) mutually suit constitute, interior pipe two ends are opening, interior pipe, propellant powder (12) is housed in the interlayer between the outer tube, and end face has sealing blanking cover (19), and outer tube-surface is provided with symmetrical 4 spit tubes (23) and 4 empennages (13), aluminium foil blanking cover (22) is equipped with in the spit tube outlet, be connected by the through hole on the outer tube (26) between propellant powder (12) and the spit tube (23), be contained in the fuse (20) in the propellant powder (12), its end is located at the grain surface, empennage (13) is hinged with outer tube (24), can open in 90 ° of scopes or closure.Grain (25) is contained in the launching tube (16), launching tube (16) structure includes percussion lock (21), sighting device (10), (15), carries handle (17), shoulder drags (18), alignment pin (9), pin porose and that cooperate with the hole (14) on the launching tube, grain (25) is connected with launching tube (16), is located by alignment pin (9).The rope of arranging in certain sequence (7) is housed in the collection rope roll (8) of body, the descending lifeline that is connected with the collection rope roll is a kind of object with some through holes, its rope (7) one ends are connected by each through hole of descending lifeline (6) and the connecting ring (2) on the bullet (3), and the other end is fastening by the centre bore and the pin on the launching tube (14) of pipe (11) in the grain.

The course of work is: ready body is packed in the launching tube (16), the connecting ring (2) of rope two ends and bullet and the pin (14) of launching tube are fixed respectively, make an accurate selection of target, by percussion lock (21) percussion fuse (20), light propellant powder (12), after the gas of propellant powder produces certain pressure, break through the aluminium foil blanking cover (22) on the spit tube (23), gas sprays backward by launching tube, promotes body disengaging launching tube simultaneously and travels forward, empennage opens, because spit tube is gas jet backward continuously, promote missile rotation forward, when being transmitted into predeterminated target, breaking needle punctures target obstacle, hook closes up to body at momentum effect lower compression spring, after removing impulse force, under spring action, hook opens, and hooks object.Rope makes the involute curved rope of collection rope roll decontrol along with the flight of body, the rope other end is fixed on the launching tube.When the user caught descending lifeline to glide along rope, himself gravity made bullet and descending lifeline push the junction that is connected to separate, because rope complications on descending lifeline are passed each hole, when descending lifeline and rope are subjected to displacement, the resistance that the friction of tortuous place produces can slowly descend the people, the ground of arriving safe and sound.
