As shown in fig. 1 and 2, with the above arrangement, the falling of the elevator cab 200 in the present embodiment can be prevented by the fall protection device when it falls down rapidly due to a malfunction of the cab; the acceleration sensor on the lifting cabin 200 is used for the acceleration of downward movement of the lifting cabin 200, when the lifting cabin 200 loses control and rapidly drops, the detection data detected by the acceleration sensor are compared by the trigger controller, and when the detected acceleration is higher than the set value of the trigger controller, the brake plate 500 can be operated by the brake mechanism to move towards one side of the anti-drop rail 300, so that the speed reduction wheel set 400 is in rolling contact with the anti-drop rail 300 and an anti-lock unit is triggered to reduce the speed of the lifting cabin 200; that is, when the brake plate 500 moves to the side of the anti-drop rail 300, the deceleration wheel set 400 is in rolling engagement with the friction surface of the anti-drop rail 300, and the anti-lock unit can prevent the deceleration wheel set 400 from being locked, and the anti-lock unit continuously acquires the speed signal of the wheel from the wheel speed sensor and processes the speed signal during the deceleration braking of the deceleration wheel set 400, so as to determine whether the wheel is about to be locked, thereby reducing the braking distance and lowering the elevator cabin 200.
As shown in fig. 1 and 2, when the elevator car 200 is lowered in speed by the deceleration action of the deceleration wheel set 400, the telescopic mechanism controls the locking plate 600 to contact with the fall prevention rail 300 to engage the locking latch with the mating latch, and finally stops the movement of the elevator car 200. The anti-falling device in the embodiment stops the movement of the lifting cabin 200 through the deceleration braking and the corresponding structure locking, so that the safety accident caused by the falling of the lifting cabin 200 is avoided, and the anti-falling device has higher safety guarantee.
As described above, the braking mechanism in this embodiment is used for decelerating the lifting cabin 200, in order to avoid the braking mechanism from being damaged due to inertia when the lifting cabin 200 descends, in this embodiment, a shock-absorbing block 700 in sliding fit with the lifting cabin 200 is disposed at one side of the lifting cabin 200 corresponding to the anti-falling rail 300, shock absorbers 800 are disposed at the upper and lower ends of the shock-absorbing block 700, and the braking mechanism is mounted on the shock-absorbing block 700. In this way, since the damper block 700 is installed on the elevator car 200 through the damper 800, when the brake mechanism is operated to brake, a certain inertial force can be counteracted by the damper 800, and a buffering and decelerating effect can be achieved, thereby avoiding damage to the brake mechanism.
As shown in fig. 1 and 2, when the elevator cabin 200 descends rapidly due to a fault, the friction surface of the anti-falling guide rail needs to be contacted by the speed reduction wheel set 400 through a braking mechanism, namely the braking mechanism needs to enable the speed reduction wheel set 400 to move towards the anti-falling guide rail, the braking mechanism in the embodiment comprises a fork-shear type stretching frame 900 positioned between a braking plate 500 and a damping block 700, two ends of the braking plate 500 are further provided with a positioning column 1000 and a control stud 1100 which are horizontally arranged, the positioning column 1000 is in plug-in fit with the damping block 700, one end of the control stud 1100 is in threaded fit with the braking plate 500, and the other end of the control stud 1100 is in transmission connection with a motor assembly arranged on the damping block 700, and the motor assembly is in signal connection with a trigger controller.
As shown in fig. 1 and 2, in order to improve the braking effect of the reduction gear set 400, the present embodiment is provided with a friction block 1200 on the reduction gear set 400, and when the reduction gear set 400 is in rolling contact with a friction surface, the friction block 1200 is in close contact with the friction surface.

Thus, when the speed of the lifting cabin 200 is reduced under the action of the speed reducing wheel set 400, the hydraulic cylinder 1400 can be extended to support and expand, so that the locking plate 600 is in close contact with the anti-falling guide rail, and when the locking latch on the locking plate 600 is meshed with the matching latch on the anti-falling guide rail, the lifting cabin 200 can be promoted to stop gradually.
As shown in fig. 1 and 2, after the fall protection device of the lifting cabin 200 is triggered, the fall protection track 300 should be replaced at a proper time due to the fact that the surface friction coefficient is reduced by friction, so as to avoid failure, the fall protection track 300 in this embodiment includes an inner layer and an outer layer, the inner layer and the outer layer are detachably connected, the friction surface and the locking latch are arranged on the inner layer in parallel, and a fixing frame fixedly connected with the lifting frame is arranged on the outer side of the outer layer. Thus, the falling protection rail 300 can be mounted on the lifting frame through the fixing frame, and the inner layer of the falling protection rail 300 can be detached after use due to the fact that the inner layer and the outer layer can be detached separately. And the replacement of technicians is facilitated.
In practical application, when the elevator cabin 200 has been lowered to the lowest position in the deceleration mistake, in order to reduce the impact and avoid the injury of personnel in the elevator cabin 200 to the maximum extent, the embodiment is provided with a buffer mechanism under the elevator cabin 200, which is located at the lower end of the elevator, and the buffer mechanism comprises a buffer plate 1500, a plurality of shock absorbing springs 1600 are provided under the buffer plate 1500, and the shock absorbing springs 1600 are mounted on a buffer table 1700 located at the lower end of the elevator. In this way, when the lift cabin 200 is in contact with the buffer plate 1500, the impact force generated from the lift cabin 200 can be absorbed by the damper springs 1600, thereby avoiding safety accidents caused by direct contact of the lift cabin 200 with the ground.
In addition, in some embodiments, after the lifting cabin 200 falls down, the lifting cabin may stay at a certain position of the lifting frame under the deceleration action of the anti-falling device, in order to facilitate personnel in the cabin to escape as soon as possible, in this embodiment, a U-shaped protection frame 1800 arranged from top to bottom is arranged on one side of the lifting frame 100, a protection net 1900 is laid on the protection frame 1800, an escape stair 2000 installed on the lifting frame is arranged in the protection frame 1800, and an emergency cabin door 2100 is arranged on one side of the lifting cabin 200 corresponding to the protection frame.
