Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a material transportation device for an electromagnetic shielding room. Background Technology

[0002] Material transportation and handling are crucial aspects of the construction and maintenance of electromagnetic shielding rooms. Electromagnetic shielding rooms are typically used to prevent electromagnetic interference (EMI) or ensure electromagnetic compatibility (EMC). These rooms require specialized building materials, equipment, and precise installation processes. Electromagnetic shielding rooms usually require large areas of thick, heavy metal sheets; these materials are not only heavy but also typically bulky. How to efficiently and safely handle these materials is a key issue that must be addressed during transportation.

[0003] For example, Chinese Patent CN113386837A discloses a material transport device for an electromagnetic shielding room, including a base, an auxiliary bearing assembly, a fixing frame, an adjusting assembly, and a fourth hydraulic rod. Rollers are installed around the bottom of the base. The first hydraulic rod is fixed to both ends inside the first bearing plate. The fixing frame is fixed to the front and rear surfaces of the left side of the base. The movable disc is rotatably connected to the inside of the horizontal plate. The fourth hydraulic rod is fixed to the surface of the mounting frame. This material transport device for an electromagnetic shielding room is equipped with a vertical rod and second hydraulic rods. The two sets of second hydraulic rods on the surface of the horizontal plate drive the clamping plate to slide towards one end of the central axis of the base, clamping the material. In conjunction with the rack on the surface of the vertical rod, the second motor drives the gear to rotate, causing the vertical rod to slide upwards on the top of the fixing frame. This allows the vertical rod to lift the horizontal plate and the material upwards, facilitating material handling and avoiding the inconvenience of manual handling, thus reducing the labor intensity of workers.

[0004] However, traditional material handling equipment often requires workers to move heavy objects onto the loading vehicle during transportation. When dealing with large and heavy materials, loading and unloading is not only very troublesome, but also poses a risk of injury from falling objects. Furthermore, manual handling is inefficient, labor-intensive, and unsafe. During transportation, materials are prone to friction with the loading container, which can accelerate wear and tear, and vibration can also cause damage to the materials, resulting in losses.

A loading box 3 is fixedly connected to the top of the loading vehicle 1. A sliding plate 4 is slidably connected to the inner wall of the loading box 3. A telescopic flexible belt 5 is fixedly connected to one side of the sliding plate 4. A telescopic assembly is provided at the bottom of the inner wall of the loading box 3, allowing the sliding plate 4 to slide up and down.

A support plate 7 is fixedly connected to the top of the internal gear ring 6. The top of the support plate 7 is fixedly connected to the support plate 8 and the support frame 9. The support plate 8 is equipped with a hydraulic rod 10, and the support frame 9 is equipped with a loading and unloading assembly. Through the coordinated use of the support plate 7, the hydraulic rod 10, the drive assembly, and the loading and unloading assembly, the lifting plate 23 can be raised and lowered, and the loading and unloading assembly can be rotated. This enables the loading and unloading of materials without manual handling, improving work efficiency, shortening operation time, and reducing labor costs. Furthermore, by adjusting the distance between the lifting plates 23, the size of the materials can be automatically adapted, enhancing the flexibility and adaptability of the system.

[0030] Both sides of the loading vehicle 1 and the lifting vehicle 2 are fixedly connected to fixed blocks 11. A hydraulic rod 12 is fixedly connected to the opposite side of each fixed block 11. The hydraulic rod 12 connects the loading vehicle 1 and the lifting vehicle 2, allowing the extension end of the hydraulic rod 12 to push the lifting vehicle 2 back and forth during loading and unloading, making loading and unloading easier and avoiding interference during material unloading. The telescopic assembly includes several fixed rods 13 fixedly installed on both sides of the inner wall of the loading box 3. Two moving blocks are slidably connected to the outer wall of each fixed rod 13. 14. Two springs 15 are sleeved on the outer wall of the fixed rod 13. The two ends of the springs 15 are fixedly connected to one side of the moving block 14 and the inner wall of the loading box 3, respectively. The top of the two moving blocks 14 are fixedly connected to the connecting seat 16. The inner wall of the connecting seat 16 is hinged to the connecting rod 17. One end of the connecting rod 17 is hinged to the push plate 18. The push plate 18 is fixedly connected to the sliding plate 4. The hinge between the connecting seat 16 and the connecting rod 17, and the hinge between the connecting rod 17 and the push plate 18, both have a damping force, so that the device can maintain a stable state.

[0031] The drive assembly includes a drive motor 19 fixedly installed at the bottom of the inner wall of the lifting vehicle 2. A gear 20 is fixedly connected to the output end of the drive motor 19. The gear 20 meshes with the internal gear ring 6. The loading and unloading assembly includes a movable frame 21 slidably installed on the support frame 9. A crossbar 22 is fixedly connected to the inner wall of the movable frame 21. Two lifting plates 23 are slidably connected to the outer wall of the crossbar 22. An electric telescopic rod 24 is fixedly connected to one side of the movable frame 21. A push block 25 is fixedly connected to the telescopic end of the electric telescopic rod 24. The minimum distance between the two push plates 18 is the diameter of the electric telescopic rod 24. The top of the movable frame 21 is fixedly connected to the telescopic end of the hydraulic rod 10.

[0032] Working principle: First, prepare the materials to be transported. Then, connect the loading vehicle 1 and the lifting vehicle 2 together via hydraulic rod 12. The lifting plate 23 can then slide along the outer wall of the crossbar 22 according to the size of the material, thereby adjusting the distance between the two lifting plates 23. The lifting plate 23 has a certain damping on the crossbar 22. At this point, the carrier can be pushed so that the lifting plate 23 contacts the bottom of the material. Then, hydraulic rod 10 is activated, and the telescopic end drives the moving frame 21 to slide along the support frame 9, thus lifting the material. The lifting stops when the material is lifted to a height greater than that of the loading box 3. Then, the drive motor 19 is started, and its output end drives the gear 20 to rotate, thereby allowing the gear 2... The internal gear ring 6 with 0 meshing rotates, which in turn drives the support plate 7 to rotate, enabling the loading and unloading components to rotate. When the material is above the loading box 3, according to the principle of loading and unloading from far to near, the hydraulic rod 12 can be controlled to shrink to the shortest distance, so that the distance between the loading vehicle 1 and the lifting vehicle 2 is shortened. Then, the hydraulic rod 10 is controlled to shorten, so that the lifting plate 23 is lowered. When it is in contact with the sliding plate 4, the electric telescopic rod 24 is activated. The telescopic end drives the push block 25 to move, so that the material is put into the loading box 3. During this process, the extension and retraction of the hydraulic rod 12 can also be controlled so that the lifting plate 23 is not interfered with by the material during unloading, so that the material handling can be completed without manual intervention, thus improving safety.

[0033] When materials are placed in the loading box 3, if the transportation process involves a bumpy road, the sliding plate 4 will be lowered by the force, causing the push plate 18 to fall synchronously. This will cause the connecting rod 17 to push the moving block 14 to slide, compressing the spring 15 and causing it to retract to dampen the loading box 3. This reduces friction between the materials and the loading box 3 during transportation, reduces material wear, and also reduces wear on the loading box 3, extending its service life.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
