Description
Technical field
The utility model relates to a kind of life-saving apparatus form high building tool, particularly a kind of high building descending lifeline.
Background technology
The descending lifeline of at present disclosed band brake mechanism, majority still adopts traditional brake pad braking, as XJS-1 type planet gear type skyscraper brucker survival capsule, the braking of employing brake pad, owing to be directly to adopt centrifugal force that the brake pad in its race is thrown away and the wheel hub inwall friction that rubs, with control downhill race speed.This control mode needs big starting power, and makes decrease speed instability when just having begun.In addition, its load capacity is less, can only carry a people at every turn, can not satisfy the demands under emergency situation.And utilize the centrifugal mechanism complex structure, processing technology requires high, makes complete machine cost height, and economic serviceability is not strong, can not satisfy public demand.All adopting cruise control aspect the operation speed governing, can't adjust automatically accurately according to the situation of individuality, simultaneously, rope separates with reducing gear, and structure is disperseed, and storage is inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of easy to operate, and good reliability is simple in structure, and storage is convenient, the high building descending lifeline that cost is low.
A kind of high building descending lifeline, its structural feature is: comprise bracing frame, be arranged at the rotating shaft side by side of two on the bracing frame, be arranged with rope respectively in two rotating shafts arranged side by side, two rotating shafts arranged side by side realize rotating synchronously by actuating unit, a rotating shaft therein is provided with drive unit, rear in rotating shaft side by side also is provided with the 3rd axle, this is on the plane with the plane parallel at two rotating shaft places arranged side by side and with two rotating shafts arranged side by side and becomes perpendicular position, space, being positioned at rope in two rotating shafts arranged side by side walks around respectively behind the 3rd axle and is fallen thing and fix, the rotating shaft that is provided with drive unit is provided with brake apparatus, also is provided for the jockey that is fixed on bracing frame.
The high building descending lifeline of this structure, when needs use, it is fixed on building or other object with jockey, then select the number of turns of rope around the 3rd rotating shaft according to the weight of being fallen thing, then start drive unit, by the rotating speed of driving device controls rotating shaft arranged side by side, to guarantee that being fallen thing safety descends, when stopping to drive, being fallen thing will stop to descend, when the needs brake hard, can utilize the brake apparatus braking, thereby play the effect of dual fail-safe.Therefore high building descending lifeline of the present invention has simple in structurely, operate easy for installationly, stores the advantage that cost etc. are cheap.
Described drive unit or be hand drive promptly is provided with handwheel in rotating shaft.
Described drive unit or for power drive, as adopting motor etc.
Described two arranged side by side transmission devices between the axle or to adopt gearratio be that 1 chain passes band, or to adopt gearratio be 1 band transmission, or to adopt gearratio be 1 gear drive.
Described brake apparatus is the click structure, and ratchet is installed on the driving shaft that has drive unit, and ratchet is installed on the bracing frame.
When needs are braked, make ratchet block ratchet and just can realize braking.
Outer peripheral face at the 3rd axle is arranged with sleeve, and sleeve can rotate around the 3rd axle, and rope is around on the sleeve.
Mode at winding rope on the axle arranged side by side is after on the axle arranged side by side the wiring frame being set, with the rope winding thereon.
The sleeve of the 3rd axle is provided with the stopper slot that is used for the winding rope.
Jockey on the bracing frame or for adopting rope binding formula to connect, or for adopting screw thread to be connected with the external world.
In sum, the utility model has following advantage compared to existing technology:
The utility model utilizes the Euler's formula F of flexible body friction
1=F
2e
α fMake mechanism reach the location with similar movable pulley mechanism, control speed, labour-saving effect.Use of the present utility model is not subjected to limitation in height, can select different ropes long according to the building is high; Flexible for installation, selecting different mounting means according to actual conditions; Applied widely, such as: residential building, hotel, school, hospitals and other places; Total operates laborsaving, good reliability, and real-time is good, detachably for ease of maintenaince; And the device simple in structure, technological requirement is low, makes cost step-downs such as material, processing, assembling.The utility model not only can effectively be controlled the speed of decline, and volume is little, is convenient to store and carry.During use, once can carry many people according to the pulling force of rope.This practicality can be used for high building burst fire incident and in time flees from the disaster area and rescue life for people.
