Below the principle of work of elevator of the present invention is described below:
Elevator running environment control principle is under causing whole building powering-off state because of accidents such as fire, and elevator automatic or manual switching can enter fire prevention emergency operating pattern.Fire screen release gear 12 release above elevator door 22 has high-performance fire-resistant, the soft curtain 14 of multi-layer fireproofing of high temperature-proof and anti-blowing and fire resistant curtain 23, meanwhile automatically or can the special Fireproof elevator door 18 of manual unlocking and car door 15, and the same period special Fireproof elevator door protection cross bar 17 and car protection cross bar 16 auto-extending; Thus make elevator 31 be difficult to form chimney effect, for treating that rescue group is by the good environmental conditions of the descending maintenance of elevator.
Elevator power-off self-operating lifesaving principle is causing automatically realizing under power-transfer clutch 3 powering-off state the connection of traction wheel shaft 4 with damping arrangement 5 input end because of accidents such as fire, under power-transfer clutch 35 powering-off state for subsequent use automatically or select manually to realize the connection of guide wheel shaft 36 and damping arrangement 34 input end for subsequent use.Afterwards, automatic or manual controls the power-off brake guard mode of traction sheave drg 2 pairs of traction sheaves 3, make car 32 and counterweight 29 under gravity, one end that quality is large accelerates to move downward, meanwhile, along with the increase of steel rope 30 moving velocity of interlock, damping arrangement 6 is driven synchronously to produce larger dumping force by traction sheave 3 and power-transfer clutch 5, in order under the certain running velocity of elevator, consume counterweight 29 end and the car 32 end kinetic energy transformed at decline current situation the subject of knowledge and the object of knowledge of poor quality, namely when the gravitational difference of the effect that the dumping force that damping arrangement 6 produces and other friction force produce and car 32 and counterweight 29 balances each other, the large one end of both middle quality is remained a constant speed move downward, afterwards bottom elevator 31 shock absorber 25 or 28 effect under slow down after stop motion, traction sheave drg 2 also automatically holds traction wheel shaft 4 tightly under control system controls, thus make car 32 stop at architectural top 21 or bottom 26 state, first consider that car 32 stops at architectural top 21 state, top layer 21 treats that special Fireproof elevator door protection cross bar 17 and car protection cross bar 16 manually push back in special Fireproof elevator door 18 and car door 15 by rescue group respectively, treats that rescue group passes the soft curtain 14 of fire prevention and enters car 32 rear protecting cross bar 16,17 automatic spring and play protective action.Then, traction sheave drg 2 also under control system controls automatically or manually remove the brake action to traction wheel shaft 4 by personnel in car 32, and in the case, because the car 32 under fully loaded or heavy condition is large more than counterweight 29 gravity, car 32 first accelerates to move downward and at the uniform velocity moves downward under damping arrangement 6 acts on, afterwards bottom elevator 31 car shock absorber 25 effect under slow down after stop motion, traction sheave drg 2 holds traction wheel shaft 4 automatically tightly simultaneously, and now car 32 is in the state stopping at building bottom 26; Now, in car 32 personnel manually car is protected cross bar 16 and elevator door protection cross bar 17 push back in car door 15 and elevator door 18, just through the soft curtain 14 of multi-layer fireproofing can withdraw out lift car 32 smoothly and transfer to safety zone.Subsequently, car 32 can the unloaded or a small amount of fire-fighting and rescue personnel of underloading, under the information reporting of building fire supervisory system, manually or automatically controlled by emergency flight control center machine 10, remove the brake action of traction sheave drg 2 pairs of traction wheel shafts 4, and under counterweight 29 Action of Gravity Field, car 32 rises to from the nearest refuge story of conflagration area or specific preferential layer, and startup traction sheave drg 2 makes car 32 stop rising again.Afterwards, as top layer 21 before this salvage, car 32 is walked out with the up a small amount of fire-fighting and rescue personnel of car 32, enter and carry out follow-up rescue work of extinguishing fire from the nearest refuge story of conflagration area or specific preferential layer, and enter car 32 from the nearest refuge story of conflagration area or specific preferential layer personnel order, and at heavy duty or the fully loaded rear brake action removing traction sheave drg 2 pairs of traction wheel shafts 4, car 32 is moved downward; And after this refuge story of last batch of personnel enter car 32, manually the special Fireproof elevator door 18 often opened can be shut, thus better fire-proof and thermal-insulation is to make to keep good running environment in elevator, in addition can suitably carry there is suitable weight article to use as similar top layer 21 clump weight 20, thus car 32 can pull counterweight 29 and move downward.Therefore, under the present invention not only can realize traction motor 1 powering-off state, the speed limit effect of damping arrangement 6 is relied on to ensure personal security, and pass through the upper and lower iterative motion of realization of poor quality of car 32 and the personnel of lift-launch and counterweight 29, can treat that rescue group is quickly transferred to bottom 26 by what collect in refuge story and top layer 21 in building, simultaneously also can by some fire-fighting and rescues personnel fast on deliver to from the nearest refuge story of the floor that needs to carry out the work.
The intelligent autonomous operation principle of elevator height: by emergency source of electrical power 8, distance measuring sensor 9, emergency flight control center machine 10 and the sensor configured at each floor and emergency control apparatus 19, select control program etc. by traction sheave drg 2 delays time to control reasonable in design, car 32 dock floor, substantially can realize fire prevention emergency operating pattern can highly intelligentized autonomous operation.
Elevator automatic water jetting cool principle is in car 32 decline process, in car 32, personnel can emergent spraying temp. lowering apparatus 39 optionally on manually opened car 32 inwall, thus the imbitition connecter 40 bottom car 32 is stretched out downwards, and when car 32 drops to bottom 26, automatically match with special water supply joint 45 and be connected, press simultaneously and open special water supply joint 45 and supply water to the water tank 44 bottom car 32; And in emergent spraying temp. lowering apparatus 39 closedown situation, the imbitition connecter 40 of cage bottom is stayed within car 32, even if also can not contact with imbitition connecter 45 when car 32 drops to bottom 26.Subsequently, in above car 32 uphill process, because emergent spraying temp. lowering apparatus 39 is opened before this, the passive water pump driver train 41 of car 32 bottom sides is stretched out and coupling rolling on cage guide to side, therefore water pump 42 is driven to be extracted out by the water in water tank 44 bottom car 32, and automatically carry out car 32 by the jet flow pipeline 43 arranged in car 32, smog work is gone in the dedusting that Fireproof elevator door 22 and elevator 31 are correlated with in the cooling of wall and elevator 31, also thus improve or keep personnel living environment, substantially prolongs the serviceable time of elevator under fire condition.
Elevator emergency self-operating high reliability principle possesses automatically and MANUAL CONTROL mode for adopting positive redundancy backup same apparatus, configuration identity function different device, crucial function unit simultaneously.Concrete measure as rope sheave messenger chain as guide wheel shaft 36 one end be connected with power-transfer clutch 35 for subsequent use and damping arrangement 34 for subsequent use the effect that rises be similar to the power-transfer clutch 5 and damping arrangement 6 that traction wheel shaft 4 one end is connected; And the emergent safety tongs 38 installed the effect that rises be similar to traction sheave drg 2; Power-transfer clutch 5 and power-transfer clutch for subsequent use 35 all have building power-off automatic operation function and manually make it work functions; In addition traction sheave drg 2 and emergent safety tongs 38 all can manually be sent electric signal instruction control by the emergency control apparatus 19 on car 32 internal controller and elevator door side or manually be carried out mechanical drive control, even if thus under making emergency source of electrical power 8 or emergency flight control center machine 10 failure condition, rely on the communication facilities such as mobile phone still can possess high-rise treat rescue group in a large number under send the upload ability with some bottoms fire fighter.
For a more clear understanding of the present invention, below in conjunction with accompanying drawing, working process of the present invention is described.
Fig. 1 is the structural representation that the present invention has the elevator of fire power-off self-operating life-saving functions; Fig. 2 is the structural representation that elevator runs to bottom.
Under causing whole building powering-off state because of accidents such as fire, elevator automatic or manual switching can enter fire prevention emergency operating pattern.Fire screen release gear 12 release above elevator door 22 has high-performance fire-resistant, the soft curtain 14 of multi-layer fireproofing of high temperature-proof and anti-blowing and fire resistant curtain 23, meanwhile automatically or can the special Fireproof elevator door 18 of manual unlocking and car door 15, and the same period special Fireproof elevator door protection cross bar 17 and car protection cross bar 16 auto-extending; Thus make elevator 31 be difficult to form chimney effect, for treating that rescue group is by the good environmental conditions of the descending maintenance of elevator.Meanwhile, automatically can realize the connection of traction wheel shaft 4 and damping arrangement 5 input end under power-transfer clutch 3 powering-off state, under power-transfer clutch 35 powering-off state for subsequent use automatically or select manually to realize the connection of guide wheel shaft 36 and damping arrangement 34 input end for subsequent use.Afterwards, automatic or manual controls the power-off brake guard mode of traction sheave drg 2 pairs of traction sheaves 3, make car 32 and counterweight 29 under gravity, one end that quality is large accelerates to move downward, meanwhile, along with the increase of steel rope 30 moving velocity of interlock, damping arrangement 6 is driven synchronously to produce larger dumping force by traction sheave 3 and power-transfer clutch 5, and when the gravitational difference of the effect that the dumping force that damping arrangement 6 produces and other friction force produce and car 32 and counterweight 29 balances each other, the large one end of both middle quality is remained a constant speed move downward, afterwards bottom elevator 31 shock absorber 25 or 28 effect under slow down after stop motion, traction sheave drg 2 also automatically holds traction wheel shaft 4 tightly under control system controls, thus make car 32 stop at architectural top 21 or bottom 26 state, first consider as shown in Figure 1, car 32 stops at architectural top 21 state, top layer 21 treats that special Fireproof elevator door protection cross bar 17 and car protection cross bar 16 manually push back in special Fireproof elevator door 18 and car door 15 by rescue group respectively, treats that rescue group passes the soft curtain 14 of fire prevention and enters car 32 rear protecting cross bar 16,17 automatic spring and play protective action.Then, traction sheave drg 2 also under control system controls automatically or manually remove the brake action to traction wheel shaft 4 by personnel in car 32, and in the case, because the car 32 under fully loaded or heavy condition is large more than counterweight 29 gravity, car 32 first accelerates to move downward and at the uniform velocity moves downward under damping arrangement 6 acts on.And in car 32 decline process, in car 32, personnel can emergent spraying temp. lowering apparatus 39 optionally on manually opened car 32 inwall, thus the imbitition connecter 40 bottom car 32 is stretched out downwards, and in emergent spraying temp. lowering apparatus 39 closedown situation, the imbitition connecter 40 of cage bottom is stayed within car 32, even if also can not contact with imbitition connecter 45 when car 32 drops to bottom 26.Car 32 at the uniform velocity moves downward bottom elevator 31, and stop motion after slowing down under the effect of car shock absorber 25, traction sheave drg 2 holds traction wheel shaft 4 automatically tightly simultaneously, elevator runs to the state of bottom as shown in Figure 2, now imbitition connecter 40 relies on Action of Gravity Field automatically to complete to be connected with the coupling of special water supply joint 45, presses simultaneously and opens special water supply joint 45 and supply water to the water tank 44 bottom car 32.Now, in car 32 personnel manually car is protected cross bar 16 and elevator door

living environment, substantially prolongs the serviceable time of elevator under fire condition.Afterwards, as top layer 21 before this salvage, car 32 is walked out with the up a small amount of fire-fighting and rescue personnel of car 32, enter and carry out follow-up rescue work of extinguishing fire from the nearest refuge story of conflagration area or specific preferential layer, and enter car 32 from the nearest refuge story of conflagration area or specific preferential layer personnel order, and at heavy duty or the fully loaded rear brake action removing traction sheave drg 2 pairs of traction wheel shafts 4, car 32 is moved downward; And after this refuge story of last batch of personnel enter car 32, manually the special Fireproof elevator door 18 often opened can be shut, thus better fire-proof and thermal-insulation is to make to keep good running environment in elevator, in addition can suitably carry there is suitable weight article to use as similar top layer 21 clump weight 20, thus car 32 can pull counterweight 29 and move downward.Therefore, under the present invention not only can realize traction motor 1 powering-off state, the speed limit effect of damping arrangement 6 is relied on to ensure personal security, and pass through the upper and lower iterative motion of realization of poor quality of car 32 and the personnel of lift-launch and counterweight 29, can treat that rescue group is quickly transferred to bottom 26 by what collect in refuge story and top layer 21 in building, simultaneously also can by some fire-fighting and rescues personnel fast on deliver to from the nearest refuge story of the floor that needs to carry out the work.By emergency source of electrical power 8, distance measuring sensor 9, emergency flight control center machine 10 and the sensor configured at each floor and emergency control apparatus 19, select control program etc. by traction sheave drg 2 delays time to control reasonable in design, car 32 dock floor, substantially can carry out fire prevention emergency operating pattern can highly intelligentized autonomous operation work.
