Specific embodiment
As shown in Figure 1, a kind of Double damping high-altitude slow-falling device, including suspension cable wheel mechanism, speed changer and air damping energy consumption
Device；
Suspension cable wheel mechanism includes suspension cable roller box 6 and the suspension cable wheel 1 being arranged in suspension cable roller box 6, main shaft 2 and suspension cable 19；
The suspension cable wheel 1 is mounted on main shaft 2, and the suspension cable 19 is wrapped on suspension cable wheel 1；Suspension cable is stretched out in the free end of the suspension cable 19
Buffer spring 20 and safe hoisting ring 22 are sequentially installed with outside roller box 6；Buffer spring sheath 21 is provided with outside the buffer spring 20.
The buffer spring 20 and buffering spring protecting sleeve 21, to buffer impact force when escape personnel begins to decline, the safety jaw
Ring 22 is to couple lap belt.
One end of the main shaft 2 is stretched out outside suspension cable roller box 6 and is arranged to square toes 3, and the other end extend into mission case 9
It is internal；The top of the suspension cable roller box 6 is provided with mounting hole 8；Cover board 4, shown 4 side of cover board are provided on the suspension cable roller box 6
Just suspension cable roller box 6 is opened or closed, the installation and maintenance of each component in suspension cable roller box 6 are facilitated.
The speed changer includes mission case 9 and the ratchet mechanism being mounted on inside mission case (referring to fig. 2)
With from axis 11；The ratchet mechanism includes a ratchet 5 and pawl 23；Master ratchet 5 and extend into inside mission case 9
Axis 2 is fixedly connected, and 5 housing of ratchet has gear III 12, and the pawl 23 is mounted on gear III 12；It is described from axis 11 simultaneously
Row has been fixedly and coaxially connected gear I 7 and gear II 10；The gear III 12 is engaged with gear I 7；
The air damping energy consumer includes air damper 13, shaft 17, a pair of magnet 14, mono- pole N 16(, a S
Pole) and the rotor 15 that is mounted in shaft 17；One end of the shaft 17 is protruded into mission case 9 and is provided with gear IV
18, the gear IV 18 is fixedly connected with shaft 17 and engages with gear II 10；The other end of the shaft 17 is located at speed changer
9 outside of cabinet is simultaneously successively fixedly connected with rotor 15, air damper 13 from inside to outside；The pair of magnet is arranged in speed changer
Outside cabinet 9, positioned at the outer peripheral surface of rotor 15.
Therefore, main shaft 2 by ratchet 5 can only one direction drive gear III 12 to rotate, the band moving gear I 7 of gear III 12, gear
I 7 by the way that from axis 11, with moving gear II 10, gear II 10 protrudes into transmission case body with moving gear IV 18, the drive of gear IV 18
Shaft 17 rotates, so that shaft 17 drives air damp type energy consumer.
In the present embodiment, the air damper 13 or it is fan or is blower or is impeller.It is passed to by speed changer
Air damper, air damping when being rotated using air damper made one, object uniform descent.The rotor 15 by iron core with around
Group is constituted.The rotor interacts with a pair of magnet being fixed on on the outside of gear box, cuts the rotor being rotating
The magnetic line of force of fixed magnetic field generates braking moment, to further increase resistance, to reduce the volume of impeller.
In use, as shown in figure 3, escape personnel is first 26 sets of location hook in the vertical of window when fire occurs for floor
On parapet, location hook 26 is firmly fixed on the wall with positioning holding screw 25.Then Double damping high-altitude slow-falling device
The mounting hole 8 of 24 upper ends is hung on location hook 26, fastens lap belt, and the hook sleeve of waistband on safe hoisting ring 22 after,
Escape personnel can climb out of outside window, delay be down to ground escape down.Its working principle: the weight G of escape personnel passes through safety
Hanging ring 22 and buffer spring 20 are transmitted to suspension cable 19, to main shaft 2 generate driving torque T, drive ratchet 5, then band moving gear III 12,
III 12 band moving gear I 7 of gear, gear II 10 is rotated coaxially with gear I 7, gear II 10 is with moving gear IV 18, final gear IV 18
Rotate driving shaft 17 makes in interaction process so that the rotation of shaft 17 drives air damper 13 and rotor 15 to rotate
The speed of decline human body, which is maintained at, to be bordering at the uniform velocity and in reasonable range, and escape personnel can be safe in extremely short time range
It lands, escapes rapidly.Meanwhile one rotor of installation and a pair of magnet phase being fixed on on the outside of gear box in impeller shaft
Interaction makes the magnetic line of force of the rotor being rotating cutting fixed magnetic field generate braking moment, to further increase resistance, to subtract
The volume of small impeller.Again due to being provided with ratchet 5, so that driving torque T can only can drive air to hinder in a regulation steering
Buddhist nun's device 13.Therefore ratchet 5 can be reversed, suspension cable 19 with handle by the square toes 3 on main shaft 2 after escape personnel's use
It is recovered on suspension cable wheel 1, for the 2nd personal use.Because of the unidirectional delivery torque of ratchet, when recycling suspension cable 19, gear
III 12 are not driven by ratchet 5, so that when recycling suspension cable 19, it is not necessary to and take very big power, the speed of recycling suspension cable 19 can be improved,
Rob the time.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure transformation made by present specification, directly or indirectly with the technology neck for being attached to other Related products
Domain is included within the scope of the present invention.
