[0031] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0032] Example 1
[0033] like Figures 3 to 6 As shown, this embodiment proposes a connecting device between bridge frames, which includes a first side plate 3, a second side plate 4, a first top plate 5 and a second top plate 6. The first side plate 3 and the second side plate 4 stand opposite to each other, and the first top plate 5 and the second top plate 6 are located between the first side plate 3 and the second side plate 4, and are both located on the top of the first side plate 3 and the second side plate 4. The first side plate 3, the second side plate 4, the first top plate 5 and the second top plate 6 form a semi-enclosed area with an opening at the bottom.
[0034] Specifically, in this embodiment, the first side panel 3 and the second side panel 4 are set up opposite to each other, and the structural dimensions are exactly the same. A chute track 11 is provided at the edges of the opposite sides of the first side panel 3 and the second side panel 4. The first top panel 5 and the second top panel 6 are inserted between the first side panel 3 and the second side panel 4 through the chute track 11. The laying track of the chute track 11 can be consistent with the edge profile of the first side panel 3 and the second side panel 4, and as close as possible to the edge of the first side panel 3 and the second side panel 4 to achieve a larger coverage area. The depth of the chute track 11 is sufficient to ensure that the first top panel 5 and the second top panel 6 will not fall off. The two ends of the chute track 11 can pass through the edges of the first side panel 3 and the second side panel 4, that is, the two ends of the chute track 11 can be connected to the outside. In this way, it is convenient for the first top panel 5 and the second top panel 6 to be directly inserted into the chute track 11 from the two ends of the chute track 11. When the first top plate 5 and the second top plate 6 are inserted into the slide track 11 and fill the slide track 11, it is necessary to ensure that the covering surface formed by the first top plate 5 and the second top plate 6 can cover the entire space below the slide track 11 to achieve a sealing effect. A rotating shaft 7 is also provided at the bottom of the first side plate 3 and the second side plate 4, and the rotating shaft 7 can be rotatably connected to the bridge frame 1.
[0035] In this embodiment, the first side panel 3 and the second side panel 4 can be a semicircular plate structure, which is easier to install. Correspondingly, the first top panel 5 and the second top panel 6 are arc-shaped plate structures. Of course, if the plate material of the first top panel 5 and the second top panel 6 is softer, the first top panel 5 and the second top panel 6 can be in the form of rectangular flat tiles, and then inserted into the slide track 11 through deformation. Since the slide track 11 is arranged at a position slightly below the edge of the first side panel 3 and the second side panel 4, the radius of the first top panel 5 and the second top panel 6 should also be slightly smaller than the radius of the first side panel 3 and the second side panel 4.
[0036] Further, in this embodiment, after the first top plate 5 and the second top plate 6 are inserted into the slide track 11, there may be a certain gap at the contact position of the first top plate 5 and the second top plate 6, which affects the sealing effect of the first top plate 5 and the second top plate 6. Therefore, in order to further enhance the sealing effect of the covering surface formed by the first top plate 5 and the second top plate 6, the second top plate 6 is arranged above the first top plate 5, and a part or all of the second top plate 6 overlaps with the first top plate 5 to cancel the connection gap between the first top plate 5 and the second top plate 6, and a fixing member can be used to fix the overlapped area between the first top plate 5 and the second top plate 6. Among them, the fixing member in this embodiment can be implemented by self-tapping screws. Self-tapping screws can make the installation, use, and change of the device more convenient and cost-saving. In addition, the material of the self-tapping screw is usually a high-grade material such as stainless steel or titanium alloy, which has strong corrosion resistance, heat resistance and cold resistance and other advantages, and can be used in harsh environments. Correspondingly, the width of the slide track 11 should also be equal to or slightly larger than the sum of the thicknesses of the first top plate 5 and the second top plate 6 to ensure that the first top plate 5 and the second top plate 6 can be inserted into the slide track 11 after overlapping.
[0037] Furthermore, in order to facilitate the movement of the first top plate 5 and the second top plate 6 in the chute track 11, the present embodiment is provided with a handle plate 8 at the end of the first top plate 5 and the second top plate 6. The handle plate 8 can extend to the outside of the first top plate 5 and the second top plate 6 to increase the contact area of the operator grasping the handle plate 8. At the same time, when the first top plate 5 and the second top plate 6 are located between the first side plate 3 and the second side plate 4, it is also necessary to ensure that the handle plate 8 is located between the first side plate 3 and the second side plate 4, so that the sliding of the first top plate 5 and the second top plate 6 in the chute track 11 will not be affected by the excessive length of the handle plate 8. The length of the handle plate 8 is equal to or slightly less than the distance between the opposite sides of the first side plate 3 and the second side plate 4, which is a more suitable range, so that the sliding of the first top plate 5 and the second top plate 6 can be not affected, and the sealing effect between the first top plate 5 and the second top plate 6 and the first side plate 3 and the second side plate 4 can be ensured.
[0038] The inter-bridge connection device of this embodiment completely covers the gap between the bridges 1 through a semi-enclosed area composed of the first side panel 3, the second side panel 4, the first top panel 5 and the second top panel 6, and the coverage can be adjusted according to the bending angle between the bridges 1 to adapt to different bending scenes of the bridges 1. At the same time, the inter-bridge connection device provided by the utility model only needs to adjust its own angle and coverage according to the different bending angles between the bridges 1. Therefore, after the original bridge is rotated at an angle, the rotatable cover plate can also block the top of the connection part between the bridges and the bridges. There is no need to specially supplement the bridge cover plate here on site, and there is no need to process the bridge 1 cover plate 2, which effectively improves the efficiency of on-site construction and installation. In addition, the inter-bridge connection device of this embodiment can also effectively protect the cables exposed to the air in the gaps between the bridges, and has a certain isolation effect against rain, snow, sand and dust, and sunlight.
[0039] Example 2
[0040] like Figure 7 As shown, this embodiment proposes a bridge, which includes an inter-bridge connection device, and the inter-bridge connection device is arranged at the end of the bridge. Among them, the specific structure of the inter-bridge connection device can refer to the content recorded in Example 1, and this embodiment will not be repeated. During actual assembly, the inter-bridge connection device is arranged at the end of the bridge 1, and ensures that the bridge 1 is located between the first side plate 3 and the second side plate 4, so that the inter-bridge connection device 1 forms a wrapped external shape for the end of the bridge 1. A through hole is opened at the corner of the end of the bridge 1, and the through hole can be used for the insertion of the rotating shaft 7 of the inter-bridge connection device 1, so as to achieve the purpose of rotatable connection between the inter-bridge connection device and the bridge 1.
[0041] Example 3
[0042] like Figure 8 and Fig. 9 As shown, this embodiment proposes a bridge frame combination system, which includes a first bridge frame 9 and a second bridge frame 10, wherein one of the first bridge frame 9 or the second bridge frame 10 is the bridge frame structure described in Example 2. For details, please refer to the contents described in Example 2, which will not be described in detail in this embodiment. This embodiment is further described by taking the first bridge frame 9 as the bridge frame structure described in Example 2 as an example.
[0043] In this embodiment, the first bridge frame 9 and the second bridge frame 10 are in a bent and laid state, and there is a gap at the connection between the first bridge frame 9 and the second bridge frame 10. The bridge frame connection device installed on the first bridge frame 9 is covered above the gap at the connection between the first bridge frame 9 and the second bridge frame 10, and then the first side plate 3 and the first bridge frame 9, the second side plate 4 and the first bridge frame 9, the first side plate 3 and the second bridge frame 10, and the second side plate 4 and the second bridge frame 10 are fixed in sequence by fixing parts, so as to completely close the gap at the connection between the first bridge frame 9 and the second bridge frame 10. When the bending state of the first bridge frame 9 and the second bridge frame 10 changes, resulting in a gap at the bottom of the first bridge frame 9 and the second bridge frame 10 instead of the cover plate 2 of the first bridge frame 9 and the second bridge frame 10, as shown in FIG. Fig.10 As shown, in this embodiment, only the through hole on the first bridge frame 9 for connecting the rotating shaft 7 needs to be adjusted, and the bridge frame connecting device on the first bridge frame 9 is adjusted to the bottom of the bridge frame, such as Fig.11 As shown, the installation process is no different from the previous one.
[0044] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
