After the rescue cabin is prepared, the cabin parking brake 51 is released, the brake handle 523 is held, the rescue cabin 1 is started, the counterweight 22 bypasses the head sheave through the steel wire rope, and the rescue cabin 1 carrying rescue personnel and rescue equipment is pulled up. In the process, the rack 41 on the running guide rail 4 is meshed with the gear shaft 42, the speed damping device damps and controls the ascending speed of the rescue capsule 1 through the damper 43, and finally the speed is kept to rise at a set speed (2.00m/s) at a constant speed. The rescue workers perform braking and deceleration in advance according to the floor marks, release the brake handle 523 after arriving at the affected floor at a slow speed, stop braking, pull the cabin-parking brake 51, and then can be put into rescue work.

When more rescue workers are needed for support or all work is finished, the rescue capsule 1 needs to be reset for standby, and the rescue capsule 1 is lowered to the placing position 101. Of course, it is also possible to go to a certain floor in the middle. Because the rescue system is manually operated in the whole process, at least one rescue worker is needed to operate the rescue cabin 1 in the descending process.

After the weight difference is calculated, the counterweight 31 which is placed on the floor in advance is loaded into the rescue capsule 1, so that the weight of the rescue capsule 1 is heavier than that of the counterweight 22. After the rescue vehicle is prepared, the parking brake 51 is released, the brake handle 523 is started, the rescue capsule 1 descends, and the rescue capsule 1 pulls the counterweight 22 to ascend through the steel wire rope. In the process, the rack 41 on the running guide rail 4 is meshed with the gear shaft 42, the speed damping device damps and controls the descending speed of the rescue capsule 1 through the damper 43, and finally the rescue capsule descends at a set speed (2.00m/s) at a constant speed. After the vehicle descends to a proper position, the vehicle is braked and decelerated in advance under the manual control of rescue workers, and the vehicle stops when reaching the placing position 101, and then the cabin-parking brake 51 is tightened. Before the rescue workers leave, the balance weight blocks 31-30 are additionally arranged on the rescue cabin 1, so that the weight of the counterweight 22 and the weight of the unloaded rescue cabin 1 are basically balanced, the rescue cabin 1 is slightly heavy (10 kg), and then the rescue cabin can leave after the cabin parking brake 51 is released. It can be understood that leaving the cabin parking brake 51 in the braking state for a long time is detrimental to the usability of the cabin parking brake 51, and therefore the cabin to be rescued 1 needs to be released after reaching the placing position 101.

And finally, after all the buildings are recovered to be normal, the counterweight 31 of each floor of the whole building can be prepared again through the elevator, so that the rescue system enters a standby state.
