[0026] Specifically, the elevator 1 is installed on the fire transport vehicle 10.The fire transport vehicle 10 can quickly deploy the elevator 1 to the appropriate position.

[0027] Specifically, the brake disc 7 includes a friction plate 11 and a threaded knob 12, the side surface of the rotating shaft 5 is provided with a limiting groove 13, the friction plate 11 is sleeved with the rotating shaft 5, and the inner side of the friction plate 11 is provided with a limiting protrusion 14 matched with the limiting groove 13, and the threaded knob 12 is threadedly connected with the rotating shaft 5.The friction plate 11 is pressed on the brake disc 7 by rotating the threaded knob 12, and the depth of the threaded knob 12 can adjust the friction between the friction plate 11 and the reel 6, so as to adjust the descent speed of the rescued personnel, and ensure that the personnel can be safely transferred to the ground.The limiting protrusion 14 of the friction plate 11 and the limiting groove 13 of the rotating shaft 5 are matched with each other, which can avoid the rotation of the friction plate 11 and the rotation of the reel 6, and keep the stability of the friction.

[0028] Preferably, a spring is arranged between the threaded knob 12 and the friction plate 11, preferably the spring is a diaphragm spring 16. The diaphragm spring 16 can provide strong spring force, the threaded knob 12 can press the friction plate 11 through the diaphragm spring 16, and the friction plate 11 can continue to be pressed after wearing to ensure the stability of the friction force.

[0030] Embodiment 2

[0031] Please refer to the accompanying drawings Figures 1-4 The difference between the embodiment and embodiment 1 is that the lifting platform 2 is provided with a sliding groove 19, the sliding groove 19 is provided with a sliding block 20, the bottom of the sliding block 20 is provided with a pressure spring 21, the side of the reel 6 is provided with a gear slot 22, and the top of the reel 6 is provided with a limiting tooth 23 matched with the gear slot 22. In the case that the brake does not fail, the personnel can slowly descend, and the gravity of the personnel acts on the reel 6, so that the reel 6 drives the sliding block 20 to press the pressure spring 21 downward. After the reel 6 moves downward by a certain distance, the gear slot 22 and the limiting tooth 23 are separated from each other, and the reel 6 can slowly rotate. In the case that the brake fails, the downward pulling force of the personnel on the rotating shaft 5 rapidly decreases, so that the reel 6 moves upward under the action of the pressure spring 21, the gear slot 22 is re-locked by the limiting tooth 23, thereby hindering the rotation of the reel 6, and ensuring the safety of the personnel.

[0032] Specifically, the top of the limiting tooth 23 is rotatably connected with a screw rod 24, the screw rod 24 is connected with a cross rod 25 through threads, and the cross rod 25 is fixed on the lifting platform 2. The initial position of the limiting tooth 23 is adjusted by rotating the threads, so as to set different triggering weights.
