Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1~5, in the embodiment of the present invention, a kind of elevator anti-fall device, it is characterized in that: the wall of well 4 around elevator sets gradually two groups from the bottom up and enters gear guide 1, often group is made up of the seamless connection of some traveling gear guide 1, and traveling gear guide 1 embeds 101 landfill in wall of well 4 by its Spina jujubae;Elevator case 6 arranges pull rope 5, rotating shaft 7 and brake module 3, arranging traveling gear 2 in rotating shaft 7, described brake module 3 is connected to form by spragging gear 301, gear slider 302, brake lever 303, pulling bar 304, lever axle center 305, stop pedestal 306, tripping spring 307, making leaf spring 308, limited block 309, touching 310, buffer spring 311;Described spragging gear 301 is arranged in rotating shaft 7, stop pedestal 306 is arranged at the lower section of spragging gear 301 and is connected with cage 6, gear slider 302, buffer spring 311 are arranged on stop pedestal 306, making leaf spring 308, limited block 309, lever axle center 305 are arranged on spragging gear 301, brake lever 303 is arranged on lever axle center 305, tripping spring 307 is arranged between making leaf spring 308 and brake lever 303, touching 310 is arranged on one end of brake lever 303, pulls bar 304 and is arranged on gear slider 302;Spragging gear 301 and the traveling gear 2 of brake module 3 are fixed locked in rotating shaft 7, and rotating shaft 7 is arranged in cage 6 by bearing.
Tripping spring 307 described in the embodiment of the present invention and buffer spring 311 are specially a kind of compression spring, and namely normality is in release conditions, and stress is in compressive state;Traveling gear 2 in described, brake module 3, rotating shaft 7 quantity consistent with the group number entering gear guide 1, be namely all two;Described wall of well 4, pull rope 5, cage 6 are not the device that the present invention invents, but the parts of elevator itself and installation environment thereof.
The gear of traveling gear 2 is identical with the gear set specifications of traveling gear guide 1, between engagement closely and movable normal, when elevator case 6 is pulled by pull rope 5 and gravity and to rise or fall motion, traveling gear 2 can climb or descending motion by rotating in traveling gear guide 1, when traveling gear 2 stops operating, elevator case 6 is the stop motion because of the stop between gear also.
When elevator motor stall or when pull rope 5 ruptures, elevator case 6 will obtain an acceleration, the speed making elevator case 6 is increased up landing by this acceleration always or brake module 3 is braked, the braking when speed declined at elevator case 6 is increased to speed A by the present invention, speed A should more than elevator case 6 normal decline speed, but can not be too big, not so under too high speed, human body can be produced injury by brake hard, by adjusting the retro-speed A that the structure proportion of brake module 3 can match for various different elevator setting, such brake module 3 will not make a mistake when elevator case 6 normal decline braking, and when cage 6 decrease speed outpaces A, brake module 3 braking makes elevator case 6 stop tenesmus, thus ensureing the personal safety of passenger.
When elevator case 6 decrease speed is less than speed A, brake module 3 will not be braked, now owing to the rotating speed of spragging gear 301 cannot provide enough centrifugal force, so the elastic force of tripping spring 307 promotes brake lever 303 to pressed against limited block 309, the touching 310 being connected with brake lever 303 will be unable to touch the pulling bar 304 being arranged on gear slider 302, gear slider 302 will not move and block spragging gear 301, so brake module 3 will not be braked, elevator case 6 continues to, but now the speed of elevator case 6 is only small will not produce danger.
When elevator case 6 decrease speed reaches speed A, the touching 310 that one end heavier for brake lever 303 is namely attached thereto by the centrifugal force that spragging gear 301 rotation produces throws away, the tripping spring 307 of brake lever 303 other end is also compressed simultaneously, now due to the rotation of spragging gear 301, the touching 310 rotated will touch and pulls bar 304 and promote the gear slider 302 being connected to pull bar 304 to move to spragging gear 301, now, brake module 3 starts braking.
Rotation along with spragging gear 301 is forced to slide to the left after engaging with spragging gear 301 by spragging gear slide block 302, the process slided will encounter buffer spring 311 and gradually reduced, also slowed down sliding speed gradually by it simultaneously, eventually hit stop pedestal 306, and stop sliding because it stops, now spragging gear 301 is also prevented from operating because of the stopping of gear slider 302, and brake module 3 is braked complete.
After spragging gear 301 stops, the rotating shaft 7 connecting spragging gear 301 is forced to stop, the traveling gear 2 being simultaneously located in rotating shaft 7 also shuts down, and after traveling gear 2 stops, elevator case 6 will stop tenesmus, the brake hard that final elevator completes because of the stop of traveling gear guide 1.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when without departing substantially from the spirit of the present invention or basic feature, it is possible to realize the present invention in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention rather than described above limits, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in the present invention.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
