Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Reference Figures 1 to 3 Figures 1 to 3 , an embodiment provided by the utility model: a quickly deployable roadbed plate, which includes two polymer plate bodies 1. An internal protective component for strengthening the polymer plate body 1 is fixedly connected inside the polymer plate body 1. The protective component includes a plurality of friction ridges 2. The bottoms of the plurality of friction ridges 2 are respectively fixedly connected to the top of the polymer plate body 1. A plurality of drainage grooves 3 are opened on the top of the polymer plate body 1. The friction ridges 2 have an arc-shaped structure. Drainage grooves 3 are arranged between adjacent rows of friction ridges 2. The groove depth of the drainage grooves 3 gradually increases from the middle to both sides;
[0032] A carbon fiber board 4 is fixedly connected inside the polymer plate body 1. The carbon fiber board 4 has extremely high strength, is light in weight and has good corrosion resistance and fatigue resistance. A styrene-butadiene rubber board 5 is fixedly connected to the bottom of the carbon fiber board 4. The styrene-butadiene rubber board 5 has good wear resistance, aging resistance and tear resistance, so that the service life of the device can be greatly increased. A foam aluminum board 6 is fixedly connected to the bottom of the styrene-butadiene rubber board 5. The foam aluminum board 6 is light in mass and has good energy absorption and shock absorption effects. Adding it to the roadbed plate can reduce the overall weight. A slag wool board 7 is fixedly connected to the bottom of the foam aluminum board 6. The slag wool board 7 has sound insulation performance and also has a certain strength. Secondary noise reduction can be achieved through the slag wool board 7. A magnesite board 8 is fixedly connected to the bottom of the slag wool board 7. The magnesite board 8 has characteristics such as fire prevention, waterproofing and relatively high strength. It can be used for the laying of temporary roads and sites in various complex environments and has a certain adaptability to bad weather and different geological conditions. The bottom of the magnesite board 8 is fixedly connected to the inner bottom end of the polymer plate body 1;
[0033] A connecting plate 11 is fixedly connected to the top of one of the polymer plate bodies 1. A splicing groove 12 is opened at the left top of one of the polymer plate bodies 1. By placing the connecting plate 11 inside the splicing groove 12, the first step of splicing the two polymer plate bodies 1 can be achieved. A clamping component for splicing the devices is fixedly connected to the right side of one of the polymer plate bodies 1. The clamping component includes two T-shaped blocks 9. The left sides of the two T-shaped blocks 9 are respectively fixedly connected to the front and rear ends of the right side of one of the polymer plate bodies 1. A T-shaped groove 10 is fixedly connected to the left side of one of the polymer plate bodies 1. The outside of the T-shaped block 9 is engaged with the inside of the T-shaped groove 10. By splicing one of the polymer plate bodies 1 in sequence from top to bottom, the T-shaped block 9 and the T-shaped groove 10 can be connected together, so that the two polymer plate bodies 1 will not separate from each other;
[0034] Reference Figure 3 And Figure 4, on both the front and rear ends of the left side of one polymer plate body 1, positioning plates 13 are fixedly connected. On the top of the positioning plates 13, stabilizing columns 15 are fixedly connected. The positioning plates 13 can provide a support platform for the stabilizing columns 15. A sliding block 16 is slidably connected to the outside of the stabilizing columns 15. A limiting block 17 is fixedly connected to the top end of the outside of the stabilizing columns 15. The sliding block 16 can slide on the outside of the stabilizing columns 15, while the limiting block 17 is fixed to the top of the stabilizing columns 15. The bottoms of the sliding block 16 and the limiting block 17 are both arc-shaped. On the front and rear ends of the bottom of the connecting plate 11, linkage shells 18 are fixedly connected. On the far ends of the two linkage shells 18, moving grooves 24 are opened. The moving grooves 24 can limit the movement of subsequent workpieces. A handle 26 is slidably connected to the inside of the moving grooves 24. The handle 26 can move up and down inside the moving grooves 24. A sliding groove 23 is opened inside the linkage shell 18. A circular slider 25 is slidably connected to the inside of the sliding groove 23. The circular slider 25 can slide inside the sliding groove 23. Since there is a stop block at the bottom of the sliding groove 23, the circular slider 25 will not fall out. A connecting column 27 is fixedly connected to the bottom of the circular slider 25;
[0035] The near ends of the two handles 26 are respectively fixedly connected to the far ends of the two circular sliders 25. By pulling the handle 26, the circular slider 25 is pulled down. At the same time, when the circular slider 25 descends, it can drive the connecting column 27 to descend. A housing 19 is fixedly connected to the bottom of the connecting column 27. When the connecting column 27 descends, it can drive the housing 19 to descend. A concave groove 20 is opened at the top of the housing 19. The bottom of the linkage shell 18 is in contact with the inside of the concave groove 20. The design of the concave groove 20 is to provide a descending space for the linkage shell 18. Springs 21 are fixedly connected to the front and rear ends inside the housing 19. The near ends of the two springs 21 are respectively fixedly connected to triangular blocks 22. The tops of the two triangular blocks 22 are respectively in contact with the front and rear ends of the bottom of the limiting block 17. The near ends of the triangular blocks 22 are respectively slidably connected to the front and rear ends of the linkage shell 18. When the housing 19 moves downward, it can drive the springs 21 and the triangular blocks 22 to move. When the triangular blocks 22 contact the limiting block 17, contraction can be achieved through the triangular blocks 22, and then the triangular blocks 22 can be clamped to the bottom of the limiting block 17.
[0036] Working principle: When multiple polymer plates 1 need to be spliced together, first, the connecting plate 11 fixed to the top of one of the polymer plates 1 is placed inside the splicing groove 12. Secondly, the T-shaped block 9 fixed to one of the polymer plates 1 is inserted into the T-shaped groove 10 from top to bottom. The damper 14 is designed to prevent the connecting plate 11 from sagging. At the same time, when the connecting plate 11 drops, it can drive the linkage housing 18 to drop. When the linkage housing 18 drops, it can drive the internal circular slider 25 and the connecting column 27 to move downward. The housing 19 fixed to the connecting column 27 can also move downward. When the housing 19 moves downward, it can drive the spring 21 and the triangular block 22 to move. When the triangular block 22 contacts the limiting block 17, it can contract through the triangular block 22, and then the triangular block 22 can be clamped at the bottom of the limiting block 17. Since the top of the limiting block 17 and the bottom of the sliding block 16 are arc-shaped, when it is necessary to separate the two polymer plates 1, by pulling the handle 26 to drive the circular slider 25 and the connecting column 27 to descend. Due to the internal design of the chute 23, when the circular slider 25 descends to the bottom of the chute 23, it will be limited. At this time, the two triangular blocks 22 squeeze both sides of the sliding block 16 to realize the expansion and contraction through the spring 21. Then, by pulling the handle 26 upward, the sliding block 16 can be driven to rise. When the sliding block 16 rises, it can contact the limiting block 17, and the two triangular blocks 22 can move upward through the surfaces of the sliding block 16 and the limiting block 17, and then the effect of separating the two polymer plates 1 can be achieved.
[0037] The designs of the polymer plate 1, the friction ridges 2, and the drainage grooves 3 have good toughness while ensuring the strength of the roadbed plate, greatly reducing the weight of the roadbed plate and facilitating the laying of the roadbed plate. The setting of the friction ridges 2 effectively avoids the problem of vehicle skidding during driving. The drainage grooves 3 not only reduce the problem of rainwater accumulation on the surface of the plate but also facilitate the cleaning and maintenance of the roadbed plate. They have the advantages of reasonable design, convenient use, safety, and firmness. At the same time, the carbon fiber plate 4, styrene-butadiene rubber plate 5, foam aluminum plate 6, slag wool board 7, and magnesite board 8 can maximize the strength of the roadbed plate and avoid being damaged by long-term vehicle rolling.
