Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0022] Example
[0023] The following is further described in conjunction with specific embodiments. Figure 1-Figure 5 As shown, this embodiment is a cross-high-speed cast-in-place beam support, including a Bailey beam 2 and a buckle frame 1, a transverse beam 3 is set under the Bailey beam 2, and a support column 4 is set under the transverse beam 3; it also includes a cover cloth 5 and a support rod 7, the support rod 7 is set under the Bailey beam 2, and the two ends of the support rod 7 are respectively connected to the Bailey beam 2, the support rod 7 is set above the cover cloth 5 for support, and the two ends of the cover cloth 5 are respectively connected to the support column 4, so that the cover cloth 5 is inclined toward the support column 4 along the support rod 7; specifically, the utility model is hung under the Bailey beam 2 A shade cloth 5 is provided, which is suspended on a supporting rod 7, and the heights of the connection points at both ends of the shade cloth 5 are lower than the heights of the supporting rod 7, and the supporting column 4 connected with the shade cloth 5 is located outside the expressway 9, so that the shade cloth 5 forms a spire-like structure. When objects fall from the bracket due to strong winds or human operating errors, they will directly fall on the shade cloth 5 and fall along the inclined surface to the side of the supporting column 4. At the same time, heavy rain can also effectively drain water to wash the shade cloth 5 to prevent material accumulation without manual cleaning, thereby ensuring the safety of high-speed driving.
[0024] like Figure 3As shown, the support rod 7 in this embodiment includes a connecting portion 71 and a rod portion 72, and the connecting portion 71 is respectively arranged at both ends of the rod portion 72; slide rails 6 are arranged on both sides of the Bailey beam 2, and the connecting portion 71 is suspended under the Bailey beam 2 and is slidably connected to the slide rails 6. In order to have a good material discharge effect and adjust the position of the support rod 7 according to the width of the highway 9, it is optimal that the support rod 7 is located in the middle of the highway 9, and the support rod 7 as a whole can slide back and forth along the slide rails 6.
[0025] Reference Figure 1-Figure 3 As shown, the rod portion 72 in this embodiment is a V-shaped structure or a U-shaped structure; specifically, in order to avoid the risk of falling objects hitting the edge of the cover cloth 5 and flipping it over, thereby causing leakage of material on the highway 9, the plane setting is likely to cause multiple local depressions in the cover cloth 5, and the material is not easy to slide down the inclined surface, so the V-shape and U-shape are set to achieve the effect of gathering material.
[0026] like Figure 2 and Figure 5 As shown, a clamp 8 is provided on the support column 4 in this embodiment, and the clamp 8 is provided with a clamping and fixing notch 81 and a tightening bolt 82. The edge of the cover cloth 5 is clamped into the clamping and fixing notch 81 and tightened by tightening the bolt 82; the length direction of the tightening bolt 82 is kept perpendicular to the length direction of the clamping and fixing notch 81; specifically, in order to facilitate the fixation of the two ends of the cover cloth 5, the edge of the cover cloth 5 is clamped into the clamping and fixing notch 81, and the tightening bolt 82 is vertically screwed in to tighten the cover cloth 5.
[0027] like Figure 5 As shown, at least two clamps 8 are provided, and the two clamps 8 are inclined toward each other, and cooperate with the supporting rod 7 so that the cover cloth 5 forms a ditch structure as a whole, thereby improving the material guiding capacity of the cover cloth 5.
[0028] like Figure 4 As shown, in order to avoid leakage of materials due to falling objects on both sides of the Bailey beam 2, the width of the material cover cloth 5 is set to be larger than the width of the Bailey beam 2 to increase the material connection range.
[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
