The main ladder rail 402 is located at the front side adjacent to the landing deck 202 and the other ladder rail is slidably engaged with the auxiliary ladder 4012 as the auxiliary ladder rail 403, located at the rear side near the hoistway 301. The length of the safe passage 301 exceeds the height of a single floor and is less than the height of two floors, and because the descending stroke of the inner frames 3 is not larger than one floor under normal conditions, the safe passage 301 with the length can ensure that the safe escape route positioned at the top of the elevator car 7 after lifting is within the protection range of the safe passage 301.

The lift 201 for lifting the inner frame 3 in the scheme is a lead screw type lift, a power mechanism of the lift 201 is arranged at the top of the outer frame 2, a lead screw of the lift 201 is longitudinally connected between the top and the bottom of the outer frame 2, the outer frame 2 is further provided with a longitudinal guide rail, and one part of a longitudinal upright post of the inner frame 3 extends outwards and is in sliding fit with the longitudinal guide rail. The two sides of the top of the inner frame 3 are respectively fixedly connected with the nut sliding blocks on the corresponding sides and ascend or descend along with the operation of the screw rod type lifter. The top of the safe channel 301 is open and extends out of the top of the outer frame 2 in an initial state, a top plate can be arranged at the top of the outer frame 2 to be connected with the independent traction device 1, and the safe channel 301 is in sliding fit with the corresponding through groove in the top plate. Since the position of the escape door does not necessarily completely correspond to the bottom of the lowered inner frame 3, the inner frame 3 may be further provided in a structure in which the bottom structure is horizontally movable with respect to the main body portion of the inner frame 3, and the bottom structure is connected to the main body portion through a fine adjustment mechanism.

The platform plate 202 is also vertically fixed with a side baffle 204 fixedly connected with the top of the outer frame 2, and the side baffle 204 is used for forming a blocking structure corresponding to two sides of the outer elevator door, so that the danger caused by the movement of personnel to two sides is prevented.

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.

Firstly, the elevator control system drives a safety floor which can be normally opened on a floor above an elevator car 7, then the rescue lifting platform is lowered to the corresponding position of the floor by controlling the independent traction device 1, the platform plate 202 is stopped after corresponding to the floor 9 of the floor, and an outer elevator door corresponding to the floor is opened along with the platform plate, so that trapped people can leave. Then, a locking mechanism 6 of the rescue lifting platform is started to be locked and fixed with an elevator guide rail, then the screw rod type lifter is started to lower the inner frame 3, the inner frame stops descending after a proximity sensor at the bottom of the inner frame 3 detects that the inner frame is close to an elevator car 7 which is suddenly stopped, the position of an escape door opening mechanism 5 is adjusted through a fine adjustment mechanism to enable the escape door opening mechanism to correspond to an escape door, so that a magnet 511 attracts a sealing plate 702, and the screw mounting and dismounting ends of an electric screw driver 501 are correspondingly connected with mounting screws 703. In the process, the safety channel 301 descends along with the descending process of the inner frame 3 and is always kept at the rear part and the outer sides of the two sides of the escape ladder lifting mechanism 4, so that the protection effect is achieved, and when trapped people climb out of the elevator car 7 from the escape ladder 401 to climb up the platform plate 202 from the rope ladder 207, the safety channel 301 can effectively prevent the people from falling off from the rear part or the two 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 rope ladder 207 reeled on the elastic retractor 208, the rope ladder 207 is further pulled out after passing through the transition guide roller 209, the ladder board 210 on the ladder board just falls into the corresponding ladder board bearing angle iron 405 when being put down along the tangential direction of the transition guide roller 209, therefore, each ladder board 210 can be borne by the ladder board bearing angle iron 405 in the process, the ladder board is supported by the ladder rack guide rails, the ladder board 210 is more stable and reliable and is difficult to swing back and forth, and the tension of the ladder rack guide rails and the rope of the rope ladder 207 is combined, 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 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 periphery 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.

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, trapped people climb upwards from the main ladder rack 4011 one by one, reach the bottom of the inner frame 3 and then continue to climb upwards to reach the height of a safe floor through the rope ladder 207 supported by the main ladder rack guide rail 402, exit from the front opening of the safe passage 301, open the folding pedal 203 to be taken on the ground of the safe floor, then move to the safe floor as soon as possible, and finish rescue after all the trapped people escape from the rescue lifting platform to the safe floor.

Obviously, the above processes can automatically complete the processes of descending to a safe floor under the control of an elevator control system, the bottom of the inner frame 3 descends 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, and a series of processes of descending the escape ladder 401 for trapped people to escape are realized without the field operation of other professional rescue workers, so that the escape ladder is not influenced by whether the professional rescue workers can arrive at the field in time, the escape efficiency of the people is greatly improved, the waiting time is reduced, and the probability that the people can receive secondary damage in the waiting time is avoided.

Simultaneously in order to ensure the security of the personnel of the process of fleing for one's life, this facility has independent locking mechanism 6, just bear by the rescue elevating platform in case climb up escape ladder 401 at the in-process that personnel flee for one's life, even consequently flee for the in-process and not reach safe floor yet, the weight that elevator car 7 bore also can reduce gradually because of the sharing of rescue elevating platform, avoid directly setting up rescue facility on elevator car 7 and lead to fleeing for the process to arouse the shock impact to elevator car 7, increase dangerous problem. And because the arrangement of the safety channel 301, the telescopic protective cover 205, the step plate bearing angle iron 405, the side baffle 204 and other protective structures effectively reduces the possibility of accidents in the process of moving trapped people from the top of the elevator car 7 to a safety floor, and greatly improves the safety of the trapped people in the process of escaping.

The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
