The shielding door linkage locking structure mainly includes a chain transmission mechanism 1, a cylinder assembly 2 and a sliding locking mechanism 3. The sliding locking mechanism 3 is installed on the chain transmission mechanism 1. The chain transmission mechanism 1 is connected to the cylinder assembly 2. Fixed pulley blocks are installed at both ends of the chain transmission mechanism 1. The chain transmission mechanism can perform chain transmission around the fixed pulley block under the drive of the cylinder assembly, and synchronously drives the sliding locking mechanism to lock the shielding door during chain transmission.

[0029] Preferably, Figure 1 As shown in other figures, the chain transmission mechanism 1 includes a chain 12 and a fixed pulley group 11, and the fixed pulley group 11 has at least two fixed pulleys, which are arranged along the axial direction of the door frame beam 4. The chain 12 is arranged around the fixed pulley group 11, and the chain 12 is interconnected with the shielding door locking seat 33 of the sliding locking mechanism 3.

[0030] like Figure 2 As shown in other figures, the shielding door linkage locking structure is provided with locking power by the cylinder assembly 2, and the locking mechanisms of each group of the shielding door are synchronously locked through the mechanical linkage mechanism. The cylinder 22 of the shielding door linkage locking structure is connected to the cylinder support 24 through the cylinder tail seat 23, and the cylinder support 24 is installed on the door frame beam 4. The connection method is bolted, and the cylinder assembly 2 is connected and fixed to the door frame beam 4. The cylinder joint 21 (cylinder piston rod head) is equipped with a cylinder Y-type joint, which is connected to the shielding door locking seat 33 through a pin shaft, driving the shielding door locking seat 33 to slide in translation. The shielding door locking seat 33 is installed on the linear guide rail 32, and the linear guide rail 32 provides support and guidance for the shielding door locking seat when it moves linearly. The linear guide rail 32 is installed on the guide rail mounting base plate 37 through bolt connection, and the guide rail mounting base plate 37 reserves a mounting flange and is fixed to the door frame beam 4 through bolt connection. In this embodiment, there are multiple shielding door locking seats 33, each shielding door locking seat 33 is connected by a chain 12 (plate chain), and the two fixed pulley blocks 11 are reversed to form a closed loop structure, so as to realize the synchronous locking function of the shielding door linkage locking structure. The fixed pulley block 11 is designed with a mounting flange at the bottom, which is connected to the door frame beam 4 by bolting. The two ends of the chain 12 are connected to the shielding door locking seats 33 of each shielding door locking structure through a connecting seat 42.
