Description
The utility model relates to a kind of under middle and high layer building generation emergency situation, the descending lifeline that is used to save oneself.
Middle and high layer building in China cities and towns caught fire as all kinds of hotels, hostel, residential building at present, happens occasionally, and the intensity of a fire has been sealed corridor, doorway sometimes, makes guest, resident be difficult in time break away from the scene of a fire, so that causes unnecessary injures and deaths.
The purpose of this utility model is to provide a kind of suitable cities and towns middle and high layer building, comprises that hotel, hostel, residential building, construction building building site etc. locate to take place under the emergency situation, is used to save oneself, i.e. the emergent again descending lifeline of safety.
The purpose of this utility model is realized by following technical scheme: it is made up of lockable reinforced steel bar ring (14), the slow main frame (18), steel core chemical fiber rope (11), waistband (19), rubber rope sheave (17) of falling, lockable reinforced steel bar ring (14) falls main frame (18) one ends and links to each other with slow, steel core chemical fiber rope (11) is sleeved on the slow belt pulley (31) that falls in the main frame (18), two ends link to each other with the belt card (20) of waistband (19) one ends respectively by three fixed sheave (9), steel core chemical fiber rope (11) wherein an end together with waistband (19) on rubber rope sheave (17); The slow main frame that falls buckle bowl (6), fixed sheave (9) formation by the gentle gear (4), main shaft (12), (13), brake pad (5), friction of falling of base plate (1), casing (2), rope drive gear (3), rope drive gear (3) is an one with belt pulley (31), be contained on the main shaft (12), rope drive gear (3) falls gear (4) and is meshed with slow, slow fall gear (4) and be contained on another main shaft (13), slow falling is placed with four identical crescent brake pads (5) on gear (4) wheel disc; Friction button bowl (6) spiral-lock is fallen on gear (4) and the brake pad (5) slow, and an end is packed on the main shaft (12), links to each other with base plate (1) by three long spiro nails (7) all around; Two main shafts (12), (13) all are riveted on the base plate (1), slow falling between gear (4) and base plate (1) is separated by by cushion block (10), be used for delaying surely falling gear (4) highly, at base plate (1) one end three fixed sheave (9) that are positive triangle arrangement are housed, fixing with backplate (8), play that steel core chemical fiber rope (11) is come out in main case, orientation reaches the groove effect of not taking off, casing (2) spiral-lock links to each other by rivet on base plate (1) all around; The length of steel core fibrillation towline (11) is decided on story height.
Lockable reinforced steel bar ring (14) is made with the chromium plating reinforcing bar of 10 millimeters of diameters, its middle part one side has a breach, breach one end is equipped with threaded and a connecting rod nut (15) that can 90 ° of rotations, the breach other end is threaded (16), connecting rod nut (15) can spin with other end screw thread (16), can pin easily and open; Steel core chemical fiber rope (11) twists into Steel cord by the multiply finer wire, the sheath of outsourcing chemical fibre braiding; Rope drive gear (3) and and belt pulley (31) be one, form by metal dust die casting, belt pulley (31) two corresponding internal faces are shaped on up and down staggered stripe shape burr (32), make steel core chemical fiber rope (11) non-slip when moving; Four identical crescent brake pads (5) are made with brass, every brake pad (5) bottom surface all is shaped on two slope shape grooves (51), slow fall gear (4) wheel disc and divide equally the quartering, all be shaped on two slope shape fins (41) on each five equilibrium, respectively with four brake pads (5) under groove (51) match; Slow fall gear (4) and also form by metal dust die casting; Base plate (1) is ellipse with casing (2) profile, all chromium plating.

Use principle is as follows:
To delay the lockable reinforced steel bar ring (14) that falls (18) one in main frame, be installed in in the several seconds on various pipelines or the prior fixture of installing on the wall, then the rubber rope sheave (17) that is wound with steel core chemical fiber rope (11) is flung at outside window, and the waistband (19) on steel core chemical fiber rope (11) other end fag end is enclosed within on people's waist, chucking, jump out outside window, the people is down landed from eminence, the gravity that produces makes steel core chemical fiber rope (11) drive belt pulley (31) rotation, driving rope drive gear (3) simultaneously rotates simultaneously, rope drive gear (3) drives slow gear (4) rotation at a high speed of falling, make and be placed on the slow brake pad (5) that falls on the gear (4) and expand outwardly, friction is buckled in top friction button bowl (7) inwall all around, rotating speed is high more, frictional force is big more, and control the rotating speed of rope drive gear (3) conversely, thereby steel core chemical fiber rope (11) decrease speed is slowed down, make people's safe falling ground, other people can be as stated above, the other end waistband of when go down in last position, bringing up (19), continue operation as stated above, recycle.Time spent not, steel core chemical fiber rope (11) one ends together with waistband (19) on rubber rope sheave (17), fall main frame (18) and be contained in together in the metal packaging box with slow, be placed on obviously the place of easily getting.
The utility model has the advantages that: simple in structure, easy to use, safe and reliable, In middle and high layer building, take place in the emergency situation, be used for saving oneself, can reduce not Necessary injures and deaths. Because base plate and the whole chromium plating of casing, so good looking appearance have Non-corrosive, the characteristics such as firm.
