[0026] The following will further describe the present application in detail with reference to the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0027] The embodiments of the present application disclose a bridge construction safety anti-falling device.

[0028] Refer to Figure 1 , the bridge construction safety anti-falling device includes a protective frame 11 and two bases 1 for supporting the protective frame 11. An adjusting member for adjusting the distance between the two bases 1 is provided between the two bases 1 along a first direction. The function of the protective frame 11 is to provide necessary protection to prevent people and objects from falling from the bridge; the two bases 1 are used to support and stabilize the protective frame 11 to ensure its stability during construction; an adjusting member for adjusting the distance between the two bases 1 is provided between the two bases 1, and the function of this adjusting member is to enable the device to be adjusted according to bridges or construction areas of different widths, so as to adapt to specific construction requirements.

[0029] A slide groove 103 is provided on the base 1 along a second direction. A slide block 109 is slidably connected in the slide groove 103. Both ends of the protective frame 11 are respectively connected to the slide blocks 109 on the corresponding bases 1. The first direction and the second direction are perpendicular to each other and both are perpendicular to the vertical surface of the protective frame 11. Both ends of the protective frame 11 are respectively connected to the slide blocks 109 on the corresponding bases 1, which enables the protective frame 11 to adapt to different construction environments and needs by adjusting the position of the slide block 109 in the slide groove 103; the first direction and the second direction are perpendicular to each other and both are perpendicular to the vertical surface of the protective frame 11, and this setting ensures the stability and adjustability of the protective frame 11 in three directions.

[0030] A threaded rod 108 is provided along the length direction of the chute 103 on the base 1. Both ends of the threaded rod 108 are rotatably fitted with the base 1. The slider 109 is in threaded fit with the threaded rod 108, and the bottom surface of the slider 109 is in contact with the bottom of the chute 103 to limit the rotation of the slider 109. The threaded fit between the slider 109 and the threaded rod 108 enables the slider 109 to move along the chute 103. The bottom surface of the slider 109 is in contact with the bottom of the chute 103 to limit its rotation. By rotating the threaded rod 108, the precise movement of the slider 109 along the chute 103 is controlled, thereby realizing the stable and accurate positioning of the protective frame 11.

[0031] The adjusting member includes a convex block 104 and a connecting rod 112 that is in threaded fit with the convex block 104. One convex block 104 is provided on each of the two bases 1. Both ends of the connecting rod 112 are respectively in threaded connection with the corresponding convex blocks 104, and the thread directions at both ends of the connecting rod 112 are opposite. The convex block 104 is provided with a threaded hole 100 for threaded connection with the connecting rod 112. This design enables the two bases 1 to move simultaneously and precisely in opposite directions by rotating the connecting rod 112, thereby realizing the fine adjustment of the distance between the two bases 1 and flexibly adapting to the requirements of bridges or construction areas with different widths.

[0032] A rotating shaft 105 is centrally provided on the connecting rod 112, and the outer diameter of the rotating shaft 105 is larger than that of the connecting rod 112. By rotating the rotating shaft 105, the connecting rod 112 can be driven to rotate synchronously. The rotating shaft 105 is designed with a relatively large diameter to facilitate the stable grasping operation by the staff. In addition, since the lever arm is designed to be relatively long, this characteristic enables the operation to be more labor-saving during the rotation process.

[0033] The protective frame 11 includes a bottom plate 107, a protective plate 111, and a connecting rod 112. A plurality of positioning holes for plug-in fit with the connecting rod 112 are provided along the length direction on the bottom plate 107. The protective plate 111 is installed between two adjacent connecting rods 112. The function of this design is to provide a flexible and stable protective structure. By providing a plurality of positioning holes on the bottom plate 107, the connecting rod 112 can be plugged and fixed at different positions to adjust the size and shape of the protective frame 11, while the protective plate 111 is installed between adjacent connecting rods 112 to form a continuous protective barrier.

[0034] Specifically, a plurality of positioning holes are uniformly distributed along the length direction of the bottom plate 107. These positioning holes provide installation positions for the connecting rods 112, allowing the spacing of the connecting rods 112 to be adjusted to meet different protection requirements. The ends of the connecting rods 112 are designed as plug-in parts that can be inserted into the positioning holes of the bottom plate 107. A card slot 110 is provided along the length direction on the outer wall of the connecting rod 112. The plug-in part is fixed in the positioning hole of the bottom plate 107. The card slot 110 provided on the connecting rod 112 is used to install the protection plate 111, ensuring the structural stability and the convenience of installing the protection plate 111. The two side edges of the protection plate 111 are designed as sliding plug-in parts that can be inserted into the card slot 110 of the connecting rod 112. The protection plate 111 is fixed between adjacent connecting rods 112 through the sliding plug-in parts, forming a continuous protection barrier. At the same time, the position and quantity of the protection plate 111 can be adjusted as needed. The diameter of the positioning hole is slightly larger than the diameter of the plug-in part of the connecting rod 112, and the hole spacing is set according to the standard length of the connecting rod 112 to ensure a firm connection. The depth and width of the card slot 110 of the connecting rod 112 match the plug-in part of the protection plate 111. The card slot 110 is provided along the length direction of the connecting rod 112 to provide multi-point fixation, plugging and fixing the protection plate 111 to ensure that the protection plate 111 does not fall off and can be stably connected between the connecting rods 112. Through this design, the bottom plate 107, the connecting rods 112 and the protection plate 111 can be flexibly assembled, providing a reliable protection effect and being convenient for adjustment and reconfiguration according to on-site requirements.

[0035] Refer to Figure 2 , a card slot 110 is provided along the length direction on the outer wall of the connecting rod 112, and the protection plate 111 is slidably plugged into the card slot 110. The function of such a design is to facilitate the installation and disassembly of the protection plate 111, and at the same time ensure the firm fixation of the protection plate 111 on the connecting rod 112. The implementation method is through the setting of the card slot 110, enabling the protection plate 111 to be slidably inserted and firmly stuck on the connecting rod 112. The specific details can be set as follows: the width and depth of the card slot 110 match the thickness of the protection plate 111 to ensure that the protection plate 111 can be smoothly inserted and is not easily detached. The length direction of the card slot 110 runs through the entire length or a preset length segment of the connecting rod 112 to facilitate the adjustment of the position of the protection plate 111 as needed. The edge of the protection plate 111 is designed as a plug-in structure that cooperates with the card slot 110 and can closely fit the inner wall of the card slot 110 after insertion. In this way, the protection plate 111 can be firmly installed on the connecting rod 112 and at the same time has the characteristics of being convenient for adjustment and disassembly.

[0036] The end of the protective plate 111 is provided with a first fastening hole 115. A fixing block 114 is arranged between adjacent protective plates 111. A bolt for fixing the fixing block 114 is arranged in the first fastening hole 115. The function of such a design is to ensure the stable connection between adjacent protective plates 111, prevent the protective plate 111 from shifting or loosening during use. The implementation method is to place the fixing block 114 at the end of adjacent protective plates 111, and then use a bolt to pass through the first fastening hole 115 to fasten the fixing block 114, thereby firmly connecting the two protective plates 111 together. The specific details can be set as follows: the diameter of the first fastening hole 115 matches that of the bolt to ensure that the bolt can pass through smoothly and be fastened. The size and shape of the fixing block 114 match the end of the protective plate 111 to provide sufficient contact area to enhance the connection strength. Corresponding screw holes are arranged on the fixing block 114 so that the bolt can firmly connect the fixing block 114 to the protective plate 111. In this way, the connection between the protective plates 111 is more stable, the overall structure is more stable, and the construction safety is ensured.

[0037] The connecting rod 112 is provided with a second fastening hole 116. A connecting block 113 is arranged between adjacent connecting rods 112. A bolt for fixing the connecting block 113 is arranged in the second fastening hole 116. The function of such a design is to ensure the stable connection between adjacent connecting rods 112 and improve the overall strength and stability of the entire protective frame 11. The implementation method is to place the connecting block 113 at the end of adjacent connecting rods 112, and then use a bolt to pass through the second fastening hole 116 to fasten the connecting block 113, thereby firmly connecting the two connecting rods 112 together and ensuring construction safety.

[0038] Refer to Figure 3 , a bayonet 119 is arranged on the slider 109, and the bottom plate 107 is in snap-fit with the bayonet 119, so that the bottom plate 107 can be disassembled. The function of such a design is to facilitate the quick installation and disassembly of the bottom plate 107, improve the construction efficiency and flexibility. The implementation method is to design a bayonet 119 on the slider 109 that cooperates with the bottom plate 107. When the bottom plate 107 needs to be installed, just insert the edge of the bottom plate 107 into the bayonet 119 and gently press it in to fix it. When disassembling, the bottom plate 107 is pulled out of the bayonet 119 with a slight force.

[0039] A convex plate 101 is arranged on the outer wall of the base 1, and a plurality of mounting holes 102 are arranged on the convex plate 101. By passing bolts through the mounting holes 102, the base 1 can be locked on the bridge or the ground surface, so that the entire bridge construction safety anti-falling device remains stable and does not move.

[0040] The implementation principle of this embodiment is as follows: The distance between the bases 1 and the position of the protective frame 11 are adjusted through the adjusting member and the slider 109 in the chute 103. The adjustment of the distance between the bases 1 is achieved by setting an adjusting member between the two bases 1. By rotating the connecting rod 112, the two bases 1 move synchronously in opposite directions, thereby changing the distance between the bases 1 to adapt to bridges or construction areas of different widths. By rotating the threaded rod 108, the slider 109 slides in the chute 103, adjusting the position of the slider 109, and further adjusting the position of the protective frame 11. This design enables the bridge construction safety anti-falling device to flexibly adjust the distance between the bases 1 and the position of the protective frame 11, providing a reliable protective effect, and at the same time facilitating adjustment and reconfiguration according to on-site requirements to ensure construction safety.
