[0029] Specifically, the turning wheel 11 cooperates with the wire rope to connect and fix the emergency safety protection baffle 10. When the emergency safety protection baffle 10 needs to be extended to both sides, the turning wheel 11 rotates, the wire rope is loosened, and the emergency safety protection baffle 10 can be moved.

[0030] The turning wheel 11 and the emergency safety protection baffle 10 are provided with a connecting frame plate 12, the steel wire rope passes through the connecting frame plate 12, and a second spring 13 is provided between the connecting frame plate 12 and the emergency safety protection baffle 10, one end of the second spring 13 is connected to the connecting frame plate 12, and the other end is connected to the emergency safety protection baffle 10.

When the emergency safety protection baffle 10 is extended, the locking plate 15 will automatically move down, and the emergency safety protection baffle 10 is abutted and fixed by the locking plate 15 to prevent the emergency safety protection baffle 10 from retracting again. The fixing effect is good, and the extension stability of the emergency safety protection baffle 10 is enhanced. A locking groove is provided in the lifting platform 2, and the locking plate 15 will be immersed in the locking groove, further ensuring that the locking plate 15 will not deflect, and the overall abutment effect is good.

The driven rack 21 and the clamping rod 22 will move upward through the gear, and the clamping rod 22 will disengage from the locking wheel 20 to release the lock, and the emergency safety protection block can be opened by the elastic force of the second spring 13. The plate 10 quickly extends to both sides, and the reaction speed is fast. The emergency safety protection baffle 10 can prevent falling objects from above from falling and injuring staff. When collapse occurs, the protection area is increased, which greatly improves safety. The positioning plate 15 will automatically move down, and the emergency safety protection baffle 10 is abutted and fixed by the positioning plate 15 to prevent the emergency safety protection baffle 10 from retracting again. The fixing effect is good, and the extension stability of the emergency safety protection baffle 10 is enhanced.

When the emergency safety protection baffle 10 needs to be extended to both sides, the turning wheel 11 rotates, the steel wire rope is loosened, and the emergency safety protection baffle 10 can move.

[0047] The connecting frame plate 12 is used to fix the second spring 13. Under normal conditions, the second spring 13 is in a compressed state. When the locking state of the turning wheel 11 is released, the emergency safety protection baffle 10 can be quickly extended to both sides by the elastic force of the second spring 13, and the reaction speed is fast.

[0048] During the movement of the emergency safety protection baffle 10, the anti-dropout slider 141 and the anti-dropout groove 14 are slidably matched to prevent the emergency safety protection baffle 10 from dropping out.

[0049] The slot 16 can prevent the wire rope from interfering with the positioning plate. When the emergency safety protection baffle 10 is extended,

[0050] Under normal conditions, the clamping rod 22 is inserted into the locking wheel 20 and is clamped with the locking wheel 20. The locking wheel 20 is coaxially connected with the spinning wheel 11, so that the spinning wheel 11 can be locked to prevent the line from being released. When the top plate 3 collapses and sinks downward,

[0051] The rack mounting body 24 is used to mount and fix the driven rack 21 and the gear. The fourth spring 25 provides a downward pressure on the driven rack 21 to ensure that the clamping rod 22 is locked with the locking wheel 20 during normal use.
