[0033] Please refer to Figure 1 、 Figure 3 And Figure 4 , stop structure includes: worm 7, worm wheel 8, two-way threaded rod 9 and stop block 10, the inside rotationally connected of guide frame 5 has worm 7, the inside symmetrical rotationally connected of guide frame 5 has worm wheel 8, and worm wheel 8 is engaged with worm 7, and the axle of worm wheel 8 is fixedly connected with two-way threaded rod 9, and the both ends of two-way threaded rod 9 are symmetrically screw-connected with stop block 10, and the bottom of guide frame 5 is fixedly connected with motor 16, and motor 16 is electrically connected with controller 6, and the output end of motor 16 is fixedly connected with worm 7, and the inside symmetrical of guide frame 5 is provided with sliding slot, and stop block 10 slides in sliding slot;
[0034] Need to explain: the side of stop block 10 that is close to each other is rough surface, can increase friction force;
[0035] Please refer to Figure 1 And Figure 5 , winding rope structure includes; winding rope frame 11, winding rope roller 12, rope 13, wheel frame 14 and roller 15, the inside fixed connection of cage 1 has winding rope frame 11, the inside rotationally connected of winding rope frame 11 has winding rope roller 12, and the side of winding rope roller 12 is provided with winding rope groove, and winding rope groove is wound with rope 13, and the inside fixed connection of cage 1 below winding rope roller 12 has wheel frame 14, and the inside rotationally connected of wheel frame 14 has roller 15, and the side of roller 15 is provided with rolling rope groove, and the top fixed connection of wheel frame 14 has ring plate 17, and the side fixed connection of winding rope roller 12 has handle 18;

[0037] The working principle of the intelligent construction elevator emergency rescue device is as follows:
[0038] Normal operation state:
[0039] When the intelligent construction elevator is in normal operation, the cage 1 is guided by the guide frame 5 to move vertically along the specified track to realize the rapid transportation of personnel and materials between different construction floors, at this time, the speed detector 3 monitors the running speed of the cage 1 in real time, and transmits the speed data to the controller 6 in the guide frame 5 in the form of an electrical signal, and the controller 6 continuously analyzes and judges the received speed signal to ensure that the running speed of the cage 1 is within the normal range.
[0040] Abnormal situation stop:
[0041] When the construction elevator appears abnormal conditions such as overspeed and out of control during operation, the speed of the cage 1 detected by the speed detector 3 will exceed the normal range, and the speed detector 3 will quickly transmit the electrical signal of the abnormal speed to the controller 6, and the controller 6 will analyze and judge the speed data after receiving the signal, and once the speed is confirmed to be abnormal, the controller 6 will quickly issue an instruction to start the motor 16 fixedly connected with the bottom of the guide frame 5 and electrically connected therewith.
[0042] After the motor 16 is started, its output end drives the worm 7 fixedly connected therewith to start rotating, since the worm 7 and the worm wheel 8 symmetrically and rotatably connected inside the guide frame 5 are in meshing relationship, the rotation of the worm 7 drives the worm wheel 8 to rotate synchronously, and since the worm wheel 8 is fixedly connected with the bidirectional threaded rod 9 at the shaft center, the rotation of the worm wheel 8 drives the bidirectional threaded rod 9 to rotate, the two ends of the bidirectional threaded rod 9 are symmetrically and threadedly connected with the stop blocks 10, and the guide frame 5 is symmetrically provided with a sliding groove inside, the stop blocks 10 slide in the sliding groove, and with the rotation of the bidirectional threaded rod 9, the stop blocks 10 move linearly towards each other along the sliding groove, until the side close to each other of the stop blocks 10 tightly contacts with the guide rail, so as to generate friction force, thereby achieving the stop of the cage 1, compared with the traditional mode of extending the clamping plate and clamping in the clamping groove of the guide column, the stop structure has a certain buffering effect, can reduce the harm to the trapped personnel in the cage 1 caused by rapid stop, and at the same time reduces the high requirement for the rigidity of the stop component, avoids the situation that the cage 1 is out of control again due to the fracture of the component;
[0043] Self-rescue of trapped personnel:
[0044] When the cage 1 is stopped due to an abnormal situation, if the position of the cage 1 is close to the bottom surface, the trapped personnel in the cage 1 can use the winding rope structure to escape, first, the trapped personnel slides the baffle 4 in the cage 1 to expose the winding rope roller 12 and the roller 15 on the inner side, then takes out the rope 13 wound in the winding rope groove on the side of the winding rope roller 12, and passes the rope 13 through the roller groove on the side of the roller 15 rotatably connected in the wheel frame 14, since the roller 15 can reduce the friction between the rope 13 and the cage 1, the winding and unwinding of the rope 13 is facilitated, at the same time, the ring plate 17 fixedly connected on the top of the wheel frame 14 can prevent the rope 13 from sliding out of the roller groove on the side of the roller 15, and ensure the safety of the rescue process;
[0045] The trapped personnel can rotate the handle 18 fixedly connected on one side of the winding rope roller 12 to rotate the winding rope roller 12 in the winding rope frame 11, so as to unfold the rope 13, after the rope 13 is completely unfolded, the trapped personnel opens the door 19 rotatably connected on the side of the cage 1 close to the roller 15, after the rope 13 is put down, the trapped personnel climbs down the cage 1 along the rope 13 and escapes from the dangerous area, the rescue mode is relatively simple to operate, and professional personnel is not needed, which can help the trapped personnel to escape in time in an emergency, and avoid the expansion of the accident due to untimely rescue.
