When the elevator is used, a reserved area is required to be arranged on the elevator shaft for parking the rescue lifting platform at ordinary times, and the rescue lifting platform and the independent traction device 1 are connected to an elevator control system for control. When the elevator slides down and is suddenly stopped and protected by the falling protector 8, the elevator system firstly measures the position of the module driving the elevator car 7 according to the existing position, and if the elevator is clamped between floors, the rescue facility needs to be started.
When the elevator car 7 falls down and stops suddenly, the car positioning module firstly starts the falling protector to fix the elevator car 7 on the elevator guide rail, then immediately determines the position information of the elevator car 7 at the moment, and sends the position information to the rescue control module. The rescue control module calculates and obtains the number of floors above the elevator car 7 according to the position information, obtains the position of a safe floor corresponding to an elevator door outside the floor of the floor, and then controls the independent traction device 1 to lower the rescue lifting platform to the position of the safe floor so that the height of the platform plate 202 is consistent with the corridor ground 9. In the process, the platform positioning module continuously positions the rescue lifting platform, sends a signal to the rescue control module after reaching the corresponding safety floor position, and immediately sends a starting signal to the platform control module.
The platform control module receives starting signal and then immediately lets locking mechanism 6 start and elevator guide rail lock to be fixed, then the elevator starts to descend inner frame 3, and the inductor that is close to in the bottom of inner frame 3 detects and stops descending after being close to elevator car 7 by scram, is close the inductor and can adopts the photoelectric type to be close the inductor, is close the inductor and locates on the sliding guide 302 that is close the emergency exit, is close the inductor slope and sets up downwards, on the orientation emergency exit the direction of shrouding 702 to adopt the method installation of symmetry setting on the sliding guide 302 of both sides. When the proximity sensors on both sides detect the closing plate 702, it is indicated that the closing plate 702 is close to the predetermined distance, the inner frame 3 can be stopped from descending, the magnet 511 is attracted to the closing plate 702, and the escape door opening mechanism 5 is started, so that the proximity sensors can immediately send signals to the platform control module.
The in-process escape way 301 that the inner frame 3 descends thereupon descends, keeps off all the time in escape ladder elevating system 4 rear and the outside of both sides, plays the guard action, and when stranded personnel climbed out elevator car 7 from escape ladder 401 to climb up the in-process escape way 301 of platform board 202 from rope ladder 207 can both effectively prevent personnel from dropping from rear or both sides. When the inner frame 3 descends, the lower part of the escape ladder lifting mechanism 4 can pull the lower end of the rope ladder 207 along with the lower end of the rope ladder 207, the rope ladder 207 wound on the elastic retractor 208 is further pulled out, the rope ladder 207 passes through the transition guide rollers 209 and then just falls into the corresponding ladder plate bearing angle iron 405 when the ladder plate 210 on the rope ladder is tangentially put down along the transition guide rollers 209, therefore, each ladder plate 210 can be born by the ladder plate bearing angle iron 405 in the process, the rope ladder plate 210 is supported by the ladder frame guide rails, the ladder plate 210 is more stable and reliable and is not easy to swing back and forth, the ladder frame guide rails and the rope ladder 207 are combined by tension of the rope, and the bearing force is also larger. Meanwhile, the telescopic protective cover 205 extends along with the downward movement of the inner frame 3, so that the area between the platform plate 202 and the bottom of the inner frame 3 can be well protected, and the vicious accident that trapped people step on the space between the ladder plates 210 to slide off due to escaping can be avoided.
When the proximity sensor is triggered, the screw loading and unloading ends of the electric screwdriver 501 are correspondingly connected with the mounting screws 703. The platform control module sends a signal to start the escape door opening mechanism 5, when the electric screwdriver 501 is started, the screw mounting and dismounting end rotates the mounting screw 703 and simultaneously rises along with the mounting screw 703 until the lower end of the mounting screw 703 is separated from the peripheral side of the door opening 701, and at this time, the corresponding sliding frame plate 504 also rises to the upper surface of the limiting block 303 along with the upper table body of the telescopic table 502 and is not blocked any more. Under the action of the pressure spring 508 of the lateral pushing structure, the whole escape door opening mechanism 5 and the sealing plate 702 adsorbed by the escape door opening mechanism are led to the side face to slide, meanwhile, the auxiliary anti-falling mechanism is moved to the door opening 701 of the escape door, the anti-falling buckle plate is turned downwards after being separated from the bottom baffle 507, the part extending outwards at the lower end of the anti-falling buckle plate is buckled on the periphery of the escape door, and the opening of the escape door and the connection of the bottom of the inner frame 3 and the elevator car 7 are completed.
Because the closing plate 702 is slid to the outside of the escape door, the position on the original escape door becomes the opened door opening 701, so that the proximity sensor cannot detect the proximity of an object and then sends a corresponding signal to the platform control module again, and the platform control module starts the escape ladder lifting mechanism 4. Then the escape ladder elevator motor 404 starts, and through the descending of rack and pinion mechanism drive escape ladder 401 thereupon, pass the emergency exits stretches into in the elevator car 7, the main ladder frame 4011 and the supplementary ladder frame 4012 of escape ladder 401 keep off respectively in the inboard of two anti-falling fasteners 506 and prevent it from taking place to rotate this moment, prevent that anti-falling fasteners 506 can play like this and hook the top of elevator car 7, play certain effect of preventing weighing down, reduce the probability that trapped personnel arouse the elevator car 7 unstability in the process of fleing. Simultaneously because both sides all have the ladder frame structure, can not only increase escape ladder 401 overall structure's intensity, the condition that the personnel take place to take off one's hands when climbing also can grasp supplementary ladder frame 4012 backward, reduces the risk that the hand-loss dropped.
After the escape ladder 401 falls to the bottom in the elevator car 7, when the flow of the escape ladder lowered by the escape ladder lifting mechanism 4 is completed, the platform control module automatically feeds back a signal that the building of the safety path is completed to the rescue control module, then the rescue control module sends a command according to the received feedback signal, and the outer elevator door corresponding to the position of the safety floor is opened through the outer elevator door control module. Trapped people climb upwards from the main ladder frame 4011 one by one, reach the bottom of the inner frame 3, then continue to climb upwards through the rope ladder 207 supported by the main ladder frame guide rail 402 to reach the height of a safety floor, exit from the front opening of the safety passage 301, open the folding pedal 203 on the ground of the safety floor, then move to the safety floor as soon as possible, and complete rescue after all trapped people escape from the rescue lifting platform to the safety floor.
Obviously, the above processes can automatically complete the process of descending to reach the safe floor under the control of an elevator control system, the bottom of the inner frame 3 is descended to the top position of the elevator car 7 which is in emergency stop, the escape door is opened and is connected with the elevator car 7, a series of processes of descending the escape ladder 401 for the trapped people to escape are provided, the rescue lifting platform is provided with an independent locking mechanism 6, once the escape ladder 401 is climbed up in the process of escaping the people, the rescue lifting platform bears the weight, even if the escape ladder 401 does not reach the safe floor in the process of escaping, the weight borne by the elevator car 7 can be gradually reduced due to the sharing of the rescue lifting platform, and the problem that the escape process causes vibration impact to the elevator car 7 and danger is increased due to the fact that rescue facilities are directly arranged on the elevator car 7 is avoided.
When the system is used for rescuing, other professional rescuers do not need to operate on site, so that the system is not influenced by whether the professional rescuers can arrive at the site in time, the escape efficiency of the personnel is greatly improved, the waiting time is reduced, and the probability that the personnel receive secondary damage in the waiting time is avoided. Meanwhile, in order to ensure the safety of people in the escape process, due to the arrangement of the protective structures such as the safety passage 301, the telescopic protective cover 205, the step plate bearing angle iron 405 and the side baffle 204, the possibility of accidents in the process of moving the trapped people from the top of the elevator car 7 to a safety floor is effectively reduced, and the safety of the trapped people in the escape process is greatly improved.
