Detailed Description
As shown in fig. 1, a dual-damping high altitude descent control device comprises a rope-suspension wheel mechanism, a transmission and an air damping energy dissipater;
the cable suspension wheel mechanism comprises a cable suspension wheel box 6, a cable suspension wheel 1 arranged in the cable suspension wheel box 6, a main shaft 2 and a cable suspension 19; the suspension cable wheel 1 is arranged on the main shaft 2, and the suspension cable 19 is wound on the suspension cable wheel 1; the free end of the suspension cable 19 extends out of the suspension cable wheel box 6 and is sequentially provided with a buffer spring 20 and a safety hanging ring 22; a buffer spring sheath 21 is arranged outside the buffer spring 20. The buffer spring 20 and the buffer spring sheath 21 are used for buffering the impact force when the evacuee begins to descend, and the safety lifting ring 22 is used for being connected with a safety belt.
One end of the main shaft 2 extends out of the suspension cable wheel box 6 and is arranged into a square head 3, and the other end of the main shaft extends into the transmission box body 9; the upper part of the suspension cable wheel box 6 is provided with a mounting hole 8; the cable suspension wheel box 6 is provided with the cover plate 4, the cover plate 4 is convenient to open or close the cable suspension wheel box 6, and installation and maintenance of all parts in the cable suspension wheel box 6 are facilitated.
The transmission comprises a transmission case 9, a ratchet mechanism (see fig. 2) arranged in the transmission case and a driven shaft 11; the ratchet mechanism comprises a ratchet wheel 5 and a pawl 23; the ratchet wheel 5 is fixedly connected with the main shaft 2 extending into the transmission box body 9, a gear III 12 is sleeved outside the ratchet wheel 5, and the pawl 23 is installed on the gear III 12; a gear I7 and a gear II 10 are coaxially and fixedly connected to the driven shaft 11 side by side; the gear III 12 is meshed with the gear I7;
the air damping energy dissipater comprises an air damper 13, a rotating shaft 17, a pair of magnets 14 and 16 (an N pole and an S pole) and a rotor 15 arranged on the rotating shaft 17; one end of the rotating shaft 17 extends into the transmission box body 9 and is provided with a gear IV 18, and the gear IV 18 is fixedly connected with the rotating shaft 17 and is meshed with the gear II 10; the other end of the rotating shaft 17 is positioned outside the transmission box body 9 and is fixedly connected with the rotor 15 and the air damper 13 from inside to outside in sequence; the pair of magnets are provided outside the transmission case 9 and on the outer peripheral surface of the rotor 15.
Therefore, the main shaft 2 can only drive the gear III 12 to rotate in one direction through the ratchet wheel 5, the gear III 12 drives the gear I7, the gear I7 drives the gear II 10 through the shaft 11, the gear II 10 drives the gear IV 18, and the gear IV 18 drives the rotating shaft 17 extending into the box body of the transmission to rotate, so that the rotating shaft 17 drives the air damping type energy dissipater.
In this embodiment, the air damper 13 is either a fan, a blower, or an impeller. The air is transmitted to the air damper through the speed changer, and the air damper is used for enabling people and objects to descend at a constant speed when the air damper rotates. The rotor 15 is composed of an iron core and a winding. The rotor interacts with a pair of magnets fixed on the outer side of the gearbox casing to enable the rotating rotor to cut the magnetic lines of force of the fixed magnetic field to generate braking torque, so that resistance is further increased, and the size of the impeller is reduced.
When the fire escape device is used, as shown in fig. 3, when a fire breaks out on a floor, an escape person firstly sleeves the positioning hook 26 on the vertical low wall of the window, and the positioning hook 26 is firmly fixed on the wall by the positioning set screw 25. Then, the mounting hole 8 at the upper end of the double-damping high-altitude descent control device 24 is hung on the positioning hook 26, the safety belt is tied, and after the hook of the belt is sleeved on the safety hanging ring 22, the escape personnel can climb out of the window and slowly descend to the ground for escape. The working principle is as follows: the weight G of the escape personnel is transmitted to the suspension cable 19 through the safety lifting ring 22 and the buffer spring 20, a driving torque T is generated on the main shaft 2 to drive the ratchet wheel 5, then the gear III 12 is driven, the gear III 12 drives the gear I7, the gear II 10 and the gear I7 rotate coaxially, the gear II 10 drives the gear IV 18, and finally the gear IV 18 rotates to drive the rotating shaft 17, so that the rotating shaft 17 rotates to drive the air damper 13 and the rotor 15 to rotate, the speed of descending the human body is kept at a nearly constant speed and in a reasonable range in the interaction process, the escape personnel can safely land in a very short time range to quickly escape. Meanwhile, a rotor is arranged on the impeller shaft and interacts with a pair of magnets fixed on the outer side of the gearbox body, so that the rotating rotor cuts magnetic lines of force of a fixed magnetic field to generate braking torque, the resistance is further increased, and the size of the impeller is reduced. And because the ratchet wheel 5 is arranged, the driving torque T can drive the air damper 13 only in one specified steering direction. Therefore, after the escape person uses the handle, the ratchet wheel 5 is reversed through the square head 3 on the main shaft 2, and the suspension cable 19 is retracted to the suspension cable wheel 1 for the use of the 2 nd person. Due to the action of the unidirectional transmission torque of the ratchet wheel, the gear III 12 is not driven by the ratchet wheel 5 when the suspension cable 19 is recovered, so that great force is not needed when the suspension cable 19 is recovered, the speed of recovering the suspension cable 19 can be increased, and the time is saved.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the content of the present invention or the direct or indirect application attached to the technical field of other related products are included in the patent protection scope of the present invention.
