Abstract
The utility model relates to a high-altitude rescuer, belonging to the technical field of self-rescuers for emergent falling from high-rise building. The utility model comprises a hanger, a cord, a base and a crank. The utility model is characterized in that the cord is wound on a winding coil in the base, the winding coil is connected with an output end of a variable-speed gear with a pair of wormgear pairs, an input end of the variable-speed gear is connected with a hand crank. The hand crank drives the winding coil to rotate via the variable-speed gear to unreel the cord at proper speed, enabling the person on the base to fall slowly for self-rescue or other overhead operation. A gear shifting mechanism comprising two pairs of gear pair with different ratio can be arranged in the variable-speed gear, enabling different working speed when the cord is reeled in or out.
Description
Affiliated technical field
The utility model relates to a kind of high-altitude Life-saving appliance, belong to a kind of from the skyscraper the urgent device that falls to saving oneself.
Background technology
Along with expanding economy, skyscraper is on the increase, and the situation that normal channel is blocked in breaking out of fire and contingency happens occasionally, at this moment, often need to save oneself to escape from window, the urgent whereabouts of balcony, people look forward to a kind of simple and practical grand building emergency falling apparatus.But this device has not yet to see and emerges.
Summary of the invention
In order to solve from grand building emergency whereabouts problem, the utility model provides a kind of hand-rail type high-altitude Life-saving appliance, and this Life-saving appliance is made up of hook, tightrope and pedestal.Hang over window or balcony place, be connected with pedestal by tightrope.Tightrope is wrapped on the wiring dish in the pedestal, but the speed change gear output of a self-locking is connected on wiring dish and the pedestal, and the input of this speed change gear is connected with crank.Emit tightrope driving the wiring disc spins with suitable speed with hand shaking, the people who is attached on the pedestal is slowly fallen with pedestal, escape and save oneself by speed change gear.Thereby the self-locking performance of speed change gear can make the rotation of wiring dish only be controlled by crank and prevent that pedestal and people from falling at a high speed.The self-locking of speed change gear can realize with the worm gear pairs transmission.Rope (or rising) is received in the reverse rotation of wiring dish when oppositely shaking crank.The wiring dish has different rotary speeies during for the retractable rope, and speed change gear can have a shifter, and the gear pair with two pairs of different speed ratios drives the wiring disc spins respectively when the retractable rope.
The beneficial effects of the utility model are, can slowly fall to escaping on skyscraper to saving oneself or be engaged in other work high above the ground.The utlity model has characteristics simple in structure, safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the transmission schematic diagram of the utility model embodiment.
Fig. 2 is an overall structure schematic diagram of the present utility model.
Fig. 3 is the utility model embodiment shifter detail drawing.
Referring to Fig. 1, Fig. 2: 1. pedestal, 2. hook, 3. tightrope, 4. crank, 5. crank axle, 6. gearbox, 7. worm gear, 8. gear, 9. gear, 10. gear, 11. gears, 12. gears, 13., 14. gears, 15. worm screws, 16. wiring dishes.
The specific embodiment
In Fig. 2, the utility model has pedestal (1), hook (2), tightrope (3).Hook (2) is hung on window or the balcony, and the people invests on the pedestal (1), shakes crank (4) and can make tightrope (2) thereby emit pedestal is fallen, and can make tightrope (3) income when oppositely shaking crank (4), and pedestal rises.
In the embodiment shown in fig. 1, crank (4) is connected with the input of gearbox (6) by crank axle (5), and gearbox (6) is connected with worm screw (15), and worm screw (15) is connected with worm gear (7); Gearbox (6), worm screw (15) are formed speed change gear jointly with worm gear (7), different operating rates is arranged when making the retractable rope, speed change gear can have a shifter, and this shifter is made up of with (14) and gear (10), axle (13) with (9), gear pair (12) the gear pair (8) of different transmission speed ratios.Gear on this shifter (10) gear (11) direct or indirect and on the wiring dish is connected, and drives the wiring dish and rotates.Gear in the shifter (8) is paid with the transmission that (9) and (14) and (12) are formed two pairs of different speed ratios respectively, pair of meshing when the retractable rope, and another is to throwing off to obtain the different transmission speed under two kinds of working conditions.
Referring to Fig. 3, shifter middle gear (8) and (14) of the utility model embodiment all have internal thread can match with two groups of external screw threads (19), (20) of axle (13) respectively, when axle (13) rotates by a certain direction, the axial thrust of screw thread is pushed gear (8) and (14) to left side, rotate with axle (13) in the screw thread position (19) of gear (8) precession shaft (13) and enter duty, gear this moment (14) then screws out screw thread (20) around the polished rod position of axle (13) the idle running state of deactivating.Axle is during (13) backward rotation, and gear (14) enters duty gear (8) state of then deactivating.
Comfort is arranged when the people is fallen with pedestal, a spring vibration damper can be installed in the hook (2) and the junction of tightrope (3).
Claims (2)
1. high-altitude Life-saving appliance, form by hook, tightrope, pedestal and crank, it is characterized in that: tightrope is wound on the wiring dish in the pedestal, the wiring dish is connected with the output of a speed change gear, and this speed change gear has at least a pair of worm gear pairs and this speed change gear input to be connected with a hand crank.
2. high-altitude according to claim 1 Life-saving appliance, it is characterized in that: have a shifter of forming by axle (13), gear pair (8) and (9), gear pair (12) and (14) in the speed change gear, have internal thread to be connected with screw thread position on the axle (13) respectively on gear (8), the gear (14).
