[0026] Specifically, when the shielding room body 1 needs to be moved, the entire moving device is first carried under the shielding room, the device is placed in the middle of the supporting legs 2, the first supporting plate 3 and the second supporting plate 4 are pulled to slide and expand to the two sides until they can abut against the inner sides of the supporting legs 2, ensuring that the device accurately matches the shielding room body 1 in position, then the second electric telescopic rod 19 is driven to extend the output end of the telescopic rod upward, the first supporting plate 14 and the second supporting plate 15 continuously move upward with the extension of the electric telescopic rod until they contact the bottom of the shielding room body 1, the electric telescopic rod is continuously driven to continuously raise the supporting plates, the entire shielding room body 1 is lifted until the supporting legs 2 are out of contact with the ground, with the cooperation of the universal pulley 7, the auxiliary pulley 9 and the external driving force, the operator can flexibly adjust the entire shielding room body 1 to change its position, the universal pulley 7 can rotate in multiple directions to facilitate adjustment of the moving direction; the auxiliary pulley 9 plays a role in auxiliary support and stable movement, according to actual needs, the moving device can be left at the bottom of the shielding room body 1 to facilitate subsequent movement again; or the moving device can be removed from the bottom of the shielding room body to enable the device to be used for moving other models of shielding room bodies 1. With this structure, the positioning and expansion process of the moving device is relatively simple, only the device needs to be moved to the appropriate position and the supporting plates need to be pulled to complete the preparation work, reducing the complexity and difficulty of the operation. The electric telescopic rod is used to lift the shielding room, without the need for large lifting equipment, the operation is more convenient and efficient. The sliding connection design of the first supporting plate 3 and the second supporting plate 4 enables the device to adapt to shielding room bodies 1 of different sizes, improving the versatility of the device. The cooperation of the universal pulley 7 and the auxiliary pulley 9 enables the shielding room to change direction flexibly during movement, enabling the shielding room to move in a small space or complex environment. During the movement, the shielding room body 1 is stably lifted and moved by the supporting plates, avoiding collisions and damage to the shielding room caused by direct carrying, protecting the integrity and performance of the shielding room.

[0027] The first supporting plate 3 and the first supporting plate 14 are both paved with slide rails 5, the second supporting plate 4 and the second supporting plate 15 are both fixedly connected with slide rods 6 at the bottom, the slide rods 6 are located inside the slide rails 5 and are in sliding connection with the slide rails 5, the auxiliary pulley 9 is threadedly connected with an adjusting rod 8 between the first supporting plate 3 and the second supporting plate 4, the adjusting rod 8 is composed of a screw and a nut, the auxiliary pulley 9 is a disc structure, and the auxiliary pulley 9 is rotatably connected with a plurality of ball bearings 10 at the bottom;

[0028] Specifically, when the device is ready to move the shielding room body 1 or adjust the position of each part, the slide rod 6 at the bottom of the first supporting plate 14 will slide in the slide rail 5 at the bottom of the first supporting plate 3, and similarly, the slide rod 6 at the bottom of the second supporting plate 15 will slide in the slide rail 5 at the bottom of the second supporting plate 4. This sliding connection allows relative displacement between the first supporting plate 14 and the first supporting plate 3, and between the second supporting plate 15 and the second supporting plate 4. When it is necessary to adjust the position relationship between the supporting plate and the supporting plate, such as when the shielding room body 1 is adapted to different heights or when the device is stored, the sliding of the slide rod 6 along the slide rail 5 can achieve this operation. When it is necessary to adjust the height of the auxiliary pulley 9 to adapt to different ground conditions or to better distribute the supporting force when lifting the shielding room body 1, the adjusting rod 8 can be operated to achieve this. Since the adjusting rod 8 is composed of a screw rod and a nut, when the nut is turned, the screw rod will move up and down on the first supporting plate 3 or the second supporting plate 4, thereby driving the auxiliary pulley 9 to rise or fall. For example, when the ground is uneven, the lower auxiliary pulley 9 can be raised to keep the device stable as a whole. During the movement of the shielding room body 1, the auxiliary pulley 9 plays a role as a supporting and moving component. When the bottom of the auxiliary pulley 9 is rotatably connected to a plurality of ball bearings 10, the ball bearings 10 will roll when in contact with the ground to reduce the friction between the auxiliary pulley 9 and the ground. When the device as a whole moves, the ball bearings 10 will roll with the movement of the auxiliary pulley 9, so that the auxiliary pulley 9 can move more smoothly on the ground, reducing the resistance during movement.
