[0049] The roller 3 is rotatably supported on the rotating shaft 5 through a bearing, and the rotating shaft 5 is fixed on the mounting seat 4. The roller 3 is rollingly arranged in a raceway formed between the upper track 1b and the lower track 1a;

[0050] The connecting frame 6 is provided with a pair (the installation structure of the two connecting frames is the same, and only one connecting frame 6 is shown in the figure) and is installed on the top of each radiation protection shielding door. Each of the connecting frames 6 is equipped with a pair of rollers 3 and is arranged on the left and right sides of the connecting frame 6. The mounting seat 4 corresponding to the roller 3 is plug-fitted with the connecting frame 6 in the transverse direction and locked by a locking plate.

[0051] In this embodiment, one end of the opening and closing portion 1c is flip-connected to the upper rail 1b on one side through a hinge 2, and the other end is detachably fixedly connected to the upper rail 1b on the other side. The upper part of the radiation protection shielding door is connected to the connecting piece, that is, the lower rail 1a is load-bearing, so the opening and closing mouth and the opening and closing portion 1c are set on the upper rail 1b. The belt is retractable, and in the process of flipping and opening the opening and closing portion 1c, the belt can be appropriately pulled outward or the belt tensioner can be loosened to avoid interference.

[0052] In this embodiment, the connecting frame 6 includes a connecting groove 6b and a connecting plate 6a. The connecting groove 6b is an inverted U-shaped structure. The connecting groove 6b is buckled on the upper part of the radiation protection shielding door and is detachably fixedly connected to the radiation protection shielding door through a first bolt. The connecting plate 6a is arranged at the bottom center of the connecting groove 6b and extends upward. The front and rear sides of the connecting plate 6a and the connecting groove 6b are reinforced by reinforcing ribs 6c. The upper end of the connecting plate 6a is folded backward to form a mounting portion 6d. The mounting portion 6d is attached to the buckle 8 and is detachably fixedly connected through a second bolt 11. The buckle 8 is connected to the belt 7 (the horizontal part of the belt 7 shown in the figure is arranged parallel to the upper track 1b and the lower track 1a). The belt 7 is driven by a motor in conjunction with a driving wheel and a driven wheel to drive the connecting frame 6 and the radiation protection shielding door to translate along the upper track 1b and the lower track 1a.

In addition, the abutting portions 6g of the U-shaped structure also serve to increase the strength of the notch 6e.

[0054] In this embodiment, the sealing plate 9 includes a main body, and a pair of ears 9a are provided at both ends of the main body. The main body seals the opening of the notch 6e and fits with the mounting seat 4. The pair of ears 9a are provided at the front and rear sides of the connecting frame 6 and are detachably fixedly connected to the connecting frame 6 through the third bolt 10 (in the figure, the threaded hole 6h of the connecting plate 6a located on one side of the notch 6e cooperates with the third bolt 10). In some embodiments, the ear 9a at one end of the upper end of the main body can also be rotatably matched with the connecting plate 6a by a pin.

[0055] In this embodiment, the roller 3 is a tapered roller 3 , and the upper rail 1 b and the lower rail 1 a are formed with a V-shaped rolling groove that matches the roller 3 .
