[0024] Specifically, Figure 3 , Figure 6 , Figure 8 and Fig.10As shown, the adjustment structure 5 includes a mounting plate 501 and a slide plate 502 slidably connected to the mounting plate 501. The two corners of the bottom end of the shielding door body 8 are each installed with a mounting plate 501 with an L-shaped cross-section through a disassembly structure 6. A second screw rod 504 is rotatably connected to the mounting plate 501. The slide plate 502 is threadedly connected to the second screw rod 504. A moving wheel 503 is installed at the bottom end of the slide plate 502. Two guide columns 506 are fixedly connected to the inside of the mounting plate 501. The slide plate 502 is slidably connected to the guide column 506. The top end of the second screw rod 504 is a hexagonal prism structure, and a wrench 505 is inserted into the top end of the second screw rod 504. The disassembly structure 6 includes two first clamping rods 601 and a first connecting frame 602 fixedly connected to the two first clamping rods 601. One side of the mounting plate 501 is slidably connected with the two first clamping rods 601. Two first clamping holes 604 are respectively provided at both ends of the shielding door body 8. The first clamping rod 601 is engaged with the first clamping holes 604. The first clamping rod 601 is sleeved with a first tension spring 603 on the outside. The two ends of the first tension spring 603 are respectively fixedly connected to the mounting plate 501 and the first connecting frame 602. Two second clamping rods 605 are slidably connected to the bottom end of the mounting plate 501. The bottom ends of the two second clamping rods 605 are fixedly connected with a second connecting frame 606 with a U-shaped cross section.

The second clamping rod 605 is sleeved with a second tension spring 607 on the outside. The two ends of the second tension spring 607 are respectively fixedly connected to the second connecting frame 606 and the mounting plate 501.When the shielding door body 8 is moved from the positioning frame 1 to the pillow bar 401, the moving wheel 503 at the bottom of the shielding door body 8 moves, and the moving wheel 503 rolls inside the guide groove 403, reducing the friction, making the movement of the shielding door body 8 easier. When the shielding door body 8 is moved to the pillow bar 401, since the moving wheel 503 is suspended in the air, the wrench 505 can be turned at this time, and the wrench 505 drives the second screw 504 to rotate, and the second screw 504 rotates to drive the slide plate 502 to descend, and the slide plate 502 descends to drive the moving wheel 503 to descend. The wheel 503 is lowered to gradually ground the moving wheel 503. At the same time, the moving wheels 503 on both sides are adjusted to make both moving wheels 503 grounded and gradually support the shielding door body 8. Then, the staff adjusts the position of the shielding door body 8 according to the installation position. The moving wheels 503 are used to support and adjust the shielding door body 8, which reduces the difficulty of moving the shielding door body 8 and improves the adjustment efficiency. After the shielding door body 8 is adjusted, the wrench 505 can be turned to raise the slide plate 502, so that the moving wheel 503 is suspended in the air, and the shielding door body 8 is supported by the pillow bar 401. The setting of the guide column 506 improves the sliding stability and the load-bearing effect of the slide plate 502. After the position is determined, the mounting plate 501 can be removed. When removing, it is only necessary to press the second connecting frame 606 downward, and the second connecting frame 606 drives the second clamping rod 605 to descend and no longer engage with the second clamping hole 608 on the shielding door body 8. At the same time, the second tension spring 607 is extended, and then the first connecting frame 602 is pulled again, so that the first clamping rod 601 is no longer engaged with the first clamping hole 604 on the shielding door body 8. At this time, the mounting plate 501 can be removed from The bottom corner of the shielding door body 8 is pulled out, and then the mounting plate 501 is disassembled, which improves the installation effect. When the mounting plate 501 is fitted with the shielding door body 8, under the tension of the first tension spring 603 and the second tension spring 607, the first clamping rod 601 and the second clamping rod 605 are respectively engaged with the first clamping hole 604 and the second clamping hole 608, and the first clamping rod 601 and the second clamping rod 605 are perpendicular to each other, so that the mounting plate 501 is fixed at the bottom corner of the shielding door body 8, which is simple to install and disassemble and improves the installation efficiency of the shielding door body 8. ;

[0025] When the present invention is in use, first, the shielding door body 8 is lifted by the lifting structure 2, and then after the fixing effect of the clamping structure 3 is released, the shielding door body 8 is pushed down along the guide groove 403. Before pushing it down, the pillow bar 401 and the cushion seat 402 can be fixed in advance at the position where the shielding door body 8 needs to be installed on the platform, and then the shielding door body 8 is moved by the positioning frame 1. When the positioning frame 1 moves to one side of the pillow bar 401, the insertion strip 406 on the cushion seat 402 is aligned with the slot 405 on the docking strip 404 at the bottom end of the positioning frame 1, and then the insertion strip 406 is inserted. Before inserting, the connecting strip 407 can be stepped on with the foot, and the connecting strip 407 slides downward to compress the spring 411 and drive the block 408 to slide downward at the same time. 406 can be fully inserted into the slot 405. After the insertion strip 406 is fully inserted into the slot 405, the spring 411 is reset and drives the connecting strip 407 to rise. The connection strip 407 rises and drives the card block 408 to engage with the card slot 409 of the insertion strip 406, thereby fixing the docking strip 404 and the positioning frame 1, and then locking the four universal wheels 7 at the bottom end of the positioning frame 1, and then transferring the shielding door body 8 from the positioning frame 1 to the pillow bar 401. One side of the positioning frame 1 is tilted and used in conjunction with the cushion seat 402, which facilitates the movement of the shielding door body 8 from the positioning frame 1 to the pillow bar 401, reducing the difficulty of installation. The setting of the guide shaft 410 improves the sliding stability of the connecting strip 407 and prevents the spring 411 from running off. Then, when the shielding door body 8 needs to be raised, the first hydraulic rod 201 can be started, the first hydraulic rod 201 is extended, and then the lifting plate 202 is driven to rise on the guide rod 203, and the lifting plate 202 supports the shielding door body 8 to rise until the moving wheel 503 at the bottom end of the shielding door body 8 is exposed, and then the motor 307 is started, and the motor 307 drives the first screw rod 308 to rotate, and the threads at both ends of the first screw rod 308 are in opposite directions, thereby driving the two second clamping plates 309 to move in reverse, so as to no longer clamp the shielding door body 8, and then the second hydraulic rod 304 is started, and the second hydraulic rod 304 is extended to drive the mounting block 30 5 rises, the installation block 305 rises and drives the slide 302 to slide on the fixing frame 301, the slide 302 rises and drives the installation cover 306 to rise, so that the second clamping plate 309 and the installation cover 306 do not block the shielding door body 8, and then the shielding door body 8 can be moved from the positioning frame 1 to the pillow bar 401. When the shielding door body 8 needs to be moved by the positioning frame 1, the shielding door body 8 to be installed is moved to the lifting plate 202 on the positioning frame 1, and the second hydraulic rod 304 is started. The second hydraulic rod 304 is contracted, and then the installation cover 306 is driven to descend to cover the top of the shielding door body 8, and then the second hydraulic rod 304 is started.
