Technical Field
[0001] This utility model relates to the technical field of highway construction protection equipment, specifically to a road and bridge construction safety protection device. Background Technology
[0002] Safety protection is a crucial aspect of road and bridge construction. Many protective devices cannot adjust their angle according to the actual construction environment, resulting in poor protective effects. Furthermore, in complex construction environments, protective devices need to have sufficient stability to resist external forces such as wind and impacts. Warning devices at construction sites are often not conspicuous enough and cannot provide effective warnings under various lighting conditions.

[0024] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0025] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described in terms of the embodiments and implementation methods.
[0026] The specific embodiments of this utility model are as follows:
[0027] A road and bridge construction safety protection device includes a base 6, on which a protective component is rotatably connected via a rotation limiting component;
[0028] The rotary limit component is used for adjusting the angle of the protective component;
[0029] The protective components are arranged in two sets symmetrically, and each set of protective components is connected to the rotation limit component.
[0030] Each set of protective components includes symmetrical support rods 2. Each pair of support rods 2 is fixed on both sides of the folding protective plate 1. Each support rod 2 has a groove 9 on its upper part. Each groove 9 contains a slider 10. The sliders 10 are passed through by guide posts 8. The guide posts 8 are fixedly connected to the support rods 2. One end of a connecting rod 15 is hinged to the lower part of one side of each slider 10. The middle of each pair of connecting rods 15 is crossed and rotatably connected. The other end of each connecting rod 15 is hinged to the lower end of the corresponding support rod 2.
[0031] Furthermore, there is a preload between the connecting rod 15 and the slider 10, a preload at the position where the connecting rod 15 is rotatably connected to each other, and a preload between the connecting rod 15 and the support rod 2. This preload provides support for the unfolded folding protective plate 1.
[0032] Furthermore, the slider 10 can also be threaded with a set screw 14, which can hold the guide post 8 for further limiting the slider 10 and the support rod 2.
[0033] In this embodiment, the folding protective plate 1 is unfolded by pulling the outer support rod 2. The support rod 2 drives the slider 10 to move, the slider 10 drives the connecting rod 15 to swing, and the connecting rod 15 drives the corresponding slider 10 to move along the guide post 8 in the slide groove 9, thus achieving the stable opening of the folding protective plate 1.
[0034] The rotation limiting assembly consists of two sets, each set of which is connected to the protective assembly. The rotation limiting assembly includes a rotating shaft 4. The lower end of one of the support rods 2 in each pair is fixed to the upper end of the rotating shaft 4. Symmetrical diagonal rods 20 are fixedly connected to the upper side of the rotating shaft 4. The outer ends of each pair of diagonal rods 20 are fixedly connected to the two ends of the arc-shaped track 17. Bolts 19 are provided inside the arc-shaped track 17. The bolts 19 are threadedly connected to nuts 18. The upper end of the bolts 19 is fixedly connected to one end of the extension arm 16, and the other end of the extension arm 16 is fixedly connected to the lower end of the corresponding support rod 2.
[0035] Furthermore, the curved track 17 matches the bolt 19, which follows the trajectory of the extension arm 16.
[0036] In this embodiment, a rotation limiting component is provided. Nut 18 and bolt 19 can limit the extension arm 16, thereby limiting the protective component. By loosening nut 18, the rotating protective component drives the rotating shaft 4 to rotate, which in turn drives the extension arm 16 to rotate. The extension arm 16 drives the bolt 19 to rotate within the arc track 17, thereby adjusting the angle of the protective component. After adjustment, tighten nut 18.
[0037] Furthermore, the protective component is connected to the warning component, which includes a swing rod 11, a warning plate 7, a connecting block 12, a vertical rod 121, and a fixing rod 13. The upper part of one side of the slider 10 in the groove 9 of the other support rod 2 in each pair of support rods 2 is fixedly connected to the fixing rod 13. The outer end of each fixing rod 13 is hinged to one end of the vertical rod 121, and the other end of each vertical rod 121 is hinged to one end of the connecting block 12. The other end of each connecting block 12 is fixedly connected to one side of the swing rod 11. The included angle between the connecting block 12 and the swing rod 11 is 80-90 degrees. The other end of the swing rod 11 is rotatably connected to the upper end of the corresponding support rod 2. The other end of the swing rod 11 is fixed to the warning plate 7, and the surface of the warning plate 7 is provided with reflective strips or warning information.
[0038] A warning post 5 is fixed to the upper center of the base 6. The warning post 5 is an LED light post and is electrically connected to a battery, which is located inside the base 6.
[0039] In this embodiment, a warning component is used for warning purposes. When the slider 10 moves, it drives the fixed rod 13 to move. The fixed rod 13 drives the vertical rod 121 to swing, the vertical rod 121 drives the connecting block 12 to swing, the connecting block 12 drives the swing rod 11 to swing, and in turn, the warning plate 7 swings. This is used to adjust the angle of the warning plate 7 so that the swing plate 7 is in an upward-standing state after the folded protective plate 1 is unfolded (e.g., Figure 1 As shown in the figure, when the folding protective plate 1 is retracted, the swing plate 7 is in the downward retracted state.
[0040] In use, by opening the folding protective plate 1 of the protective component and raising the warning plate 7, the warning post 5 is activated, which serves as a warning and protection function. The angle of the protective component can be adjusted by rotating the limit component.
[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
