[0030] In use, the first clamping block 21 is kept moving track controlled by the slide rail 2, and the second clamping block 27 is slid inside the movable slot 24 by the movable block 25, and the first clamping block 21 and the second clamping block 27 can be clamped into the gap between the pipes to fix the frame 1.
[0031] In order to improve the stability, for example, as shown in Figure 1 The frame 1 is symmetrically welded with a cross beam 11 on both sides of the outer wall, and a first door latch 15 is arranged on one side of the outer wall of the frame 1.
[0032] In use, the cross beam 11 enhances the structural strength of the device, making the installation position of the frame 1 more stable, and the first door latch 15 can be used to fix the door frame 13 to keep the door frame 13 rotating under control.
[0033] In order for personnel to enter and exit, for example, as shown in Figure 1 The frame 1 is installed with a hinge 12 on both sides of the outer wall, the hinge 12 is rotatably linked with a door frame 13 at the other end, and the door frame 13 and the frame 1 are both welded with a protective net 14.
[0034] In use, the protective net 14 welded inside the door frame 13 and the frame 1 can prevent personnel or objects from entering the isolation area, improving the safety of the device, and the design of the hinge 12 allows the door frame 13 to be easily opened and closed, facilitating personnel access or maintenance work.
[0035] In order to control the moving track, for example, as shown in Figure 2 The first clamping block 21 is installed with a slide block 23 on both sides of the outer wall, and the slide block 23 is slidably installed inside the slide rail 2.
[0036] In use, the slide block 23 installed on both sides of the first clamping block 21 allows it to slide inside the slide rail 2, which allows the position of the first clamping block 21 to be adjusted as needed. When the second door latch 16 is pushed by the worker, the second door latch 16 can push the first clamping block 21 to move, allowing the first clamping block 21 to be clamped into the gap between the pipes, thereby fixing the position of the frame 1 and keeping the position of the frame 1 inside the pipe stable.
[0037] In order to fix the second door latch 16, for example, as shown in Figure 2 The frame 1 is symmetrically installed with a connecting piece 17 on both sides of the outer wall, the connecting piece 17 is located at the lower end of the second door latch 16, and the second door latch 16 is located outside the slide rail 2.
