In the above embodiment, as shown in fig. 1 to 4, it is preferable that one end of the first pull rod 4 is connected with the pulling end of the anti-falling baffle plate 1 by the cotter pin 6, and the anti-falling device can only work after the pulling force of the first pull rod 4 disappears, so that the cotter pin 6 which is easy to break is provided, and when falling occurs, the cotter pin can be quickly broken, so that the pulling force of the first pull rod 4 quickly disappears, and the anti-falling device can work in time.
In the above embodiment, as shown in fig. 1 to 4, the first pull rod connecting piece 5 is preferably fixedly mounted on the suspension portion, the first pull rod 4 is fixedly connected with the suspension portion through the first pull rod connecting piece 5, and the first pull rod 4 can be further stably fixed on the suspension portion through the connection of the first pull rod connecting piece 5 with the suspension portion.

In the above embodiment, preferably, the hanging portion includes one of a chain, a rope, and a pull rope, which are single-sided or double-sided.
The specific anti-falling process of the vertical lifting device is divided into the following cases:
As shown in fig. 5 to 6, when the broken position of the suspension part is located below the connection position of the first pull rod 4 and the suspension part, the first pull rod 4 becomes the only connection structure, the gravity of the lifting upright post 14 of the lifter enables the cotter pin 6 to be broken, the pulling force of the first pull rod 4 on the anti-falling baffle plate 1 disappears, the downward tension provided by the tension spring 7 enables the pulling end of the anti-falling baffle plate 1 to move downwards, so that the anti-falling baffle plate 1 is driven to rotate, the limiting end of the anti-falling baffle plate 1 slides between the anti-falling block 2 and the limiting stop block 3, and at the moment, the lifting upright post 14 of the lifter can stop falling, so that the anti-falling effect is achieved.
As shown in fig. 7, when the position of the breakage of the suspension portion is located above the connection position of the first pull rod 4 and the suspension portion, the upward pulling force is lost at the lower portion of the connection position of the first pull rod 4 and the suspension portion, so that the pulling force applied by the first pull rod 4 to the fall arrest plate 1 is reduced, the downward pulling force provided by the tension spring 7 still enables the pulling end of the fall arrest plate 1 to move downward, and the same fall arrest effect as in the above process is achieved.
In particular, when the hanging portion is a bilateral chain, a steel rope or a pull rope, and when the position of the broken hanging portion is located above the connecting position of the first pull rod 4 and the hanging portion, because the connecting position of the first pull rod 4 and the hanging portion is located at one side of the hanging portion, unbalanced load occurs, that is, the pulling force applied to the fall protection baffle plate 1 by the gravity of the first pull rod 4 is reduced further.
It should be noted that, in the above-mentioned anti-falling process, the disappearance or reduction of the pulling force of the first pull rod 4 on the anti-falling baffle plate 1 occurs instantaneously, and at the same time, the pulling of the extension spring 7 and the rotation of the anti-falling baffle plate 1 until the limit end thereof is limited occur successively and rapidly, in such a process, the lift upright column 14 and the vehicle carried thereon will not generate enough impulse to damage the anti-falling block 2 and the limit stop 3, so that the above-mentioned limiting process can be implemented.
Moreover, the displacement of the elevator lifting column 14 relative to the guide column 13 is small, and the plurality of fall blocks 2 and limit stops 3 can limit the elevator lifting column 14 before it falls completely.
As shown in FIG. 8, the tooth comb lifter comprises at least one vertical lifting device and a bearing device, wherein the vertical lifting device is provided with the anti-falling device, and the bearing device is fixed on the lifting upright post 14 of the lifter.
The tooth comb lifter comprises four vertical lifting devices, wherein each vertical lifting device is arranged at one corner of the tooth comb lifter, the four vertical lifting devices lift simultaneously, and if a falling condition occurs, the falling prevention device on each vertical lifting device can prevent the falling from continuing simultaneously, so that the safety of the tooth comb lifter is further improved.
