[0062] Working principle:

[0063] When the protective device needs to be opened, the motor reducer of the driving mechanism on the left and right protective columns drives the lifting gear and the active synchronous pulley to perform a rotational movement. The lifting gear drives the lifting hinge mechanism to move upward through rack transmission. At the same time, the active synchronous pulley drives the synchronous belt to move upward. The hinge lifting frame contracts upward under the action of the synchronous belt clamping plate and the synchronous belt, and the wire rope also shortens the distance until it is lifted to the topmost end (as Figure 6 ) The protective device is in the open state;

[0064] When the protective device needs to be closed, the motor reducer of the driving device on the left and right protective columns drives the lifting gear and the active synchronous pulley to perform a rotational movement. The lifting gear drives the lifting hinge mechanism to move downward through rack transmission. At the same time, the active synchronous pulley drives the synchronous belt to move downward. The hinge lifting frame stretches downward under the action of the synchronous belt clamping plate and the synchronous belt, and the wire rope also increases the distance until it descends to the lowermost end (as Figure 7 ) The protective device is in the closed state.

[0065] In addition to the above embodiments, the present utility model further includes other embodiments. Any technical solutions formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the claims of the present utility model.
