Description
Technical field
The present invention relates to a kind of adjustable high-rise escape device, the occasion of temporarily saving oneself when being applied to the emergent accident of high building and disaster generation belongs to the engineering goods field.
Background technology
When high building breaking out of fire or plate indicates nature of danger, be positioned at the resident of building from places such as window or balconies, by simple machine, by the mode of saving oneself, the escape that descends rapidly from the open air is relatively safe, a kind of escape mode fast.In the existing all kinds of escape patent, include more than 100 kind of escape device and escape way, such as gravitational method, friction clutch formula, fluid pressure type, compressed air type, trolley formula, hand self-service, gas cylinder energy storage type, electrodynamic type, friction wheel disc drum method and laser method etc., it is higher that these install most cost, poor operability in the practicality perhaps need to by external energy, be unfavorable for maintenance, cause escape device can not spread to most of family, lost the intrinsic meaning of product.
Chinese invention patent " automatic speed-limiting life saving device in high building " (application number: 200810163860.1) disclose a kind of automatic speed-limiting life saving device in high building, be fit to many people fast-escape that circulates, have that slip velocity uniformity degree is high, double end recycles the advantage that is not subjected to sliding rope length restriction, its shortcoming is only with speed limit drum friction plate speed limit, manual braking device can not be controlled voluntarily by the survivor, and last survivor's security is the poorest; Utility model patent " escaping device for high building danger " (application number: 200420021816.4-) a kind of escape apparatus, comprise that one contains the escape apparatus of damping deceleration component and brake hard parts composition and the accessory that rope and a safety harness are used in the lifesaving of a band hook, this device is with advancing to restrict hole and rope hole, utilize the equilibrium principle between frictional force and gravity in the mechanics, by the braking rim brake, play the effect of fast braking, when its shortcoming is escape apparatus decline stall, can not automatic speed-limiting, can not repetitive cycling use, the sense of security is poor, and reliability is low; Patent of invention " life-saving apparatus form high building " (application number: 96210964.9) described life-saving apparatus form high building, the arrestment mechanism that comprises housing and interior installation thereof, arrestment mechanism has afterbody to be fishtail buffering wheel, brake lever is installed on the connecting rod, tool double brake function, the shortcoming of this device is that this escape device can't repetitive cycling be used, and survivor's sense of security is relatively poor.
A kind of simple in structure, volume is little, be beneficial to deposit, lightweight, being beneficial to when escape carrying becomes needs with the escape device of installing.
Summary of the invention
The present invention is directed to the deficiency of addressing existing escape device for high-rise buildings, propose the adjustable high-rise escape device that a kind of average family or common office building can be standing, this apparatus structure is simple, and volume is little, is beneficial to deposit; Lightweight, carrying and quick and easy for installation during escape, cost is low, can also join in addition a remote control with the rotation of control rope closing motor, after rope is regained fully, in order to allow motor stop, prevent motor damage, continuous many people's escapes are provided, and survivor's sense of security is strong.
Technical scheme of the present invention is, a kind of adjustable high-rise escape device, formed by a hardware casing, the hook on casing top and the hook on the safety belt on the person interconnect, the support member of whole escape device and connector are installed on this casing, it is characterized in that: the safety arrestment part is installed in the casing, the conductor rope part, rope receiving part and lifting slide part, in the safety arrestment part hand-operated brake system and centrifugal clutch automatic force regulating device are arranged, control halliard auto-sequencing winding mechanism is arranged in the conductor rope part, electric recovery device is arranged in the rope receiving part, there is suitable survivor to make things convenient for the retractable sliding board of erect-position in the lifting slide, have suffered in the device, utilize Worm Wheel System, its beneficial effect is to utilize survivor self body weight to produce decline power, regulating this device constant speed by two kinds of methods of hand control and automation descends, by the worm and gear large speed ratio kind of drive, be conducive to decrease speed braking, rises back to sue and labour by this device of motor-driven and a little reach the Rapid Circulation effect of escaping.
Aforesaid a kind of adjustable high-rise escape device, it is characterized in that: in the safety arrestment part hand-operated brake system and centrifugal clutch automatic force regulating installation composition are arranged, centrifugal clutch is that speed limit is 3000r/min, the driven half-clutch device stationary structure through reequiping, comprise drive hubs, brake shoe, lining face, screw, spring A, also have bearing and spacer groove in the fixing half-clutch device; The hand-operated brake system mainly is comprised of the power of accent Telescopic bar brake, comprise the handgrip loam cake, the handgrip lower cover, button, flexible cursor slide, movable block, steel ball, the movable block sleeve, contiguous block, steel wire, brake sleeve, extension sleeve, brake-shoe on the brake system, pin, pin-and-hole, brake drum, friction plate, spring B, spring C, spring D and spring connecting hole form, brake drum partly is installed on the axle, the spring connecting hole that friction plate contacts with brake drum when preventing from not braking is connected with spring C, have on the brake-shoe to form the flange that cam is connected with brake sleeve wedge-shaped slot inwall, brake sleeve and movable block sleeve with two contiguous blocks with are connected a pin axis and are connected, movable block is enclosed within the movable block sleeve, the one end colludes steel wire, separate steel wire with spring B therebetween and pass flexible cursor slide inside, movable block sleeve and flexible cursor slide connect firmly together, handgrip loam cake and handgrip lower cover link together with screw, the centre separates with button, the button both sides head on respectively steel wire, wedge-shaped slot is arranged in the brake sleeve, groove at movable block is equipped with steel ball, its beneficial effect is: when pressing button with hand, will compress the spring B on the movable block, impel steel ball to slide in the groove of movable block, so just can moving telescopic jib; Thereby steel ball will roll into hole self-locking nearest on the extension sleeve when letting go, movement along with brake sleeve, impel the folder power of brake-shoe in brake sleeve to change, clamping is downwards upwards loosened, by expansion link pressure being become frictional force so not only can be laborsaving but also can self-locking, when the button on the hand relieving accent power expansion link, expansion link will keep in position self-locking, when decrease speed surpasses the safety speed 1.5m/s of design, the centrifugal clutch speed 3000r/min that reaches capacity, at this moment centrifugal clutch produces larger centrifugal force, contact and impel its decrease speed to diminish with the outer wall on being fixed on casing, but because people's self Action of Gravity Field and reducing of centrifugal force, escape device can continue again to descend, suitably regulate the position of accent power expansion link, just can realize that escape device descends with the speed less than 1.5m/s.
