The safety performance of the steel belt lifesaving appliance is increased, and the service life of the steel belt lifesaving appliance is prolonged.
Description
The utility model provides a kind of fire-extinguishing and lifesaving device, particularly a kind of steel band lifesaving appliance that is applicable to skyscraper.
At present, the fire-extinguishing and lifesaving device that is used for skyscraper has various ways, for example builds outdoor fire exit, tubular stretch nylon life chute, the frenulum jaw braking type brucker survival capsule etc. of holding concurrently.But all there are some defectives in various degree in these lifesaving appliances.The defective that the present inventor once existed existing high building fire fighting lifesaving appliance is designed a kind of steel band lifesaving appliance (patent No. CN86207480, No. 36 bulletin of utility model patent communique the 3rd volume).This device adopts the wheel hub that is wound with steel band by speedup kinematic pair and centrifugal brake control, reaches the safe and effective purpose that apace personnel is transported to ground from skyscraper.Though it has solved the cost height that existing life-saving arrangement exists, safety inadequately, the shortcoming that can not use repeatedly, this device in actual applications, also existing some to be badly in need of outside the improvement on the structure, is to utilize rivet to clamp as the steel band clamping, and the riveted holes place of steel band can weaken its intensity; Easy clot when steel band stretches out, recovery brings difficulty etc. to steel band.
The purpose of this utility model provides a kind of improved high building fire fighting lifesaving appliance, and it can solve the defective of above-mentioned existence effectively, increases the security reliability of steel band use and steel band is successfully reclaimed.
The purpose of this utility model is achieved in that this device is on the architecture basics of existing steel band lifesaving appliance, improved to make.Control the wheel hub that is wound with steel band by the speedup kinematic pair and the centrifugal brake that are assembled in the housing, utilize the rotation of drum, make the frenulum on the suspension ring that are suspended on the steel band end, manned safely by dropping to ground on the skyscraper.Buffer unit is equipped with on its middle shell top, elastomer in the buffer unit can be made of flat spring or scroll spring, be wrapped in steel band two ends on the wheel hub and adopt the wound form fixed chuck to clamp respectively, the suspension ring chuck utilizes locking device locking, makes ratchet in the ratchet mechanism with telescopic pivot pin.Housing is suspended on the travel(l)ing rest, and travel(l)ing rest can be assembled in the socket that is fixed in skyscraper by the latch on it.
Because housing of the present utility model top is equipped with buffer unit,, improved the security reliability of lifesaving so in the lifesaving process, can eliminate the not good and impact shock power that produces of operation, thereby avoid excessive dynamic load to cause the damage of device.The steel band two ends do not utilize rivet grip solid, and adopt the wound form fixed chuck to clamp, and comparable riveted type clamping improves the intensity of steel band effectively, and the suspension ring chuck utilizes locking device locking, can guarantee that the lifesaving steel band moves rapidly and stably.Ratchet mechanism so ratio has the tooth-like ratchet of easy lodging now, more increases the reliability of using owing to adopt telescopic pivot pin to make ratchet.For easy to operate, avoid steel band when descending with the friction of building, add travel(l)ing rest, the housing of lifesaving appliance is suspended on the travel(l)ing rest, with the service life of prolongation lifesaving appliance.
Below in conjunction with accompanying drawing the utility model is further described.

Describe concrete structure of the present utility model and working condition in detail according to Fig. 1～9.This device comprises the travel(l)ing rest 18 that is hinged on the building, be suspended on the housing on the travel(l)ing rest 18 and be assembled in the drum that is wound with steel band 76, speedup kinematic pair and centrifugal brake in the housing, wherein steel band 7 two ends clamp with wound form fixed chuck 4.The steel band root adopts packing chuck 17, promptly processes groove on the hollow shaft 5 of drum 6, and steel band root coiled is curved, is pressed in the groove with circular shaft, winds with one circuit again, after the dissection type horse shoe clamp by bolt locking tightens up, steel band 7 is tightly wrapped on drum 6; Suspension ring chuck 14 is adopted in the steel band end, promptly in the suspension ring folder steel band end is entangled on the pressing plate, with bolt pressing plate is fixed tightly on the suspension ring folder again.13 lockings of suspension ring chuck 14 usefulness locking devices.Locking device 13 is made up of the shift fork that is hinged on the latch that has tensioned on the housing and has a handle, utilizes latch to be inserted in locking suspension ring chuck 14 in the jack of suspension ring chuck 14.During use, as long as the pulling handle makes latch break away from the chuck jack, suspension ring chuck 14 just involves steel band 7 under the gravity effect.Because the drum 6 that is wound with steel band is by being assembled in speedup kinematic pair and the centrifugal brake control in the housing, so the velocity variations that steel band 7 stretches is less, can guarantee the security that human body lands under qualification speed, the speedup kinematic pair is made of gear wheel 3 and pinion 2, centrifugal brake is made up of braked wheel 11 and the brake block 10 that is hinged on the braked wheel 11, wherein gear wheel 3 joins pinion 2 and braked wheel 11 affixed being integral together by do pawl-and-gearing mechanism 1 with telescopic pivot pin 12 with drum 6.Like this, when steel band 7 under the gravity effect during revolving drum 6, just can make gear wheel 3 drive pinion 2, braked wheel 11 generation quick rotation by ratchet mechanism, be hinged on brake block 10 on the braked wheel 11 under action of centrifugal force, form braking moment with the brake shell friction, limited braked wheel 11 and rotated.So under the control of speedup kinematic pair and centrifugal brake, drum 6 just under qualification speed, drives steel band and stretches out.When needs steel band 7 twines on the drum 6 again, as long as will be assembled in gear shaft 8 in the drum hollow shaft 5, be meshed with internal tooth on the hollow shaft 5, shake the handle 9 that is fixed on the gear shaft 8, just recyclable steel band 7.Simultaneously because the effect of ratchet mechanism, in the time of also can reducing winding steel 7, the frictional resistance of speedup kinematic pair and brake.Be contained in the buffer unit 16 that constitutes by elastomers such as flat spring or scroll springs on housing top, can eliminate in the lifesaving process, when not good or other fortuitous event produces impact shock because of operation, utilize elastomer to alleviate shock loading, can avoid excessive dynamic load to cause the damage of device effectively, improve the security reliability of using, particularly housing is suspended on the travel(l)ing rest 18, can avoid steel band 7 in stretching process with the contact friction or the collision of building, the security reliability that lifesaving appliance uses can not only be further improved, but also its service life can be prolonged.This travel(l)ing rest 18 utilizes the bearing pin that is fixed on building upper bracket and the bracket upright post hinged.At ordinary times time spent not, travel(l)ing rest 18 is taken off preservation.Drier 15 is contained in the empty indoor of housing below.
During use, the bearing pin of travel(l)ing rest 18 is inserted in the bearing of building, the housing of lifesaving appliance is suspended in the hook of travel(l)ing rest 18, fasten life belt and reinforce on the suspension ring of suspension ring chuck 14, handle on the pulling locking device 13, steel band just stretches under the gravity effect, makes people or weight safe falling.
