[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 ,in Figure 1 A schematic diagram of a preferred embodiment of the flipping device for traffic bridge shields provided by this utility model; Figure 2 for Figure 1 The diagram shows the overall frontal cross-sectional structure. Figure 3 for Figure 1 The diagram shows the overall three-dimensional structure. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the outer casing. Figure 5 for Figure 2 The diagram shows a schematic of the structure of the support struts unfolding; the flipping device for the traffic bridge screen includes: a flipping structure 3, which is rotated and mounted on a forklift 1; the flipping structure 3 includes a pad 31, a rotating shaft 32, and a limiting frame 33; the rotating shaft 32 connects the pad 31 and the side wall of the forklift 1 in series; one end of the pad 31 is rotatably connected to the forklift 1 through the rotating shaft 32; and the limiting frame 33 is fixed to one end of the pad 31; a limiting structure 4, which is slidably connected to the limiting frame 33; the limiting structure 4 includes a positioning plate 41 and a limiting... Bolt 42, one end of the positioning plate 41 is slidably fitted onto the limiting frame 33, and the limiting bolt 42 is threaded through one end sidewall of the positioning plate 41; drive structure 5, the drive structure 5 is installed inside the forklift 1, and the forklift 1 is provided with a slide groove 6, the pad 31 covers the surface of the slide groove 6, and a screw 54, a support rod 55 and a strut 56 are installed in the slide groove 6, the screw 54 is rotatably connected to the slide groove 6, one end of the support rod 55 is rotatably connected to the sidewall of the screw 54, and the strut 56 is threadedly connected to the other end of the screw 54.

[0023] In the specific implementation process, such as Figure 2 and Figure 4As shown, the drive structure 5 also includes a motor 51, a transmission belt 52, and pulleys 53. The motor 51 is mounted on one end of the forklift 1 and is covered by the housing 2. The pulleys 53 are respectively fixed to one end of the motor 51 and the screw 54. The pulleys 53 are connected by the transmission belt 52. The transmission belt 52 drives the screw 54 by driving the pulleys 53. This facilitates the connection between the screw 54 and the motor 51 through the transmission belt 52, and enables the motor 51 to drive the screw 54 through the transmission belt 52.

[0024] In the specific implementation process, such as Figure 2 , Figure 4 and Figure 5 As shown, one end of the support rod 55 is rotatably connected to the screw 54 via a connector, and the other end of the support rod 55 is rotatably connected to the bottom surface of one end of the pad 31 via a connector; one end of the strut 56 is rotatably connected to the screw 54 via a connector, and the other end of the strut 56 is rotatably connected to the center of the bottom surface of the support rod 55 via a connector; the length of the support rod 55 is greater than the length of the strut 56, and the length of the strut 56 is not less than half the length of the support rod 55; this allows the screw 54 to rotate, driving one end of the strut 56 to rotate with its thread, thereby allowing the strut 56 to support the deformation of the support rod 55, thus supporting the pad 31 to rotate via the rotating shaft 32, thereby preventing the pre-embedded bridge cover plate on the pad 31 from flipping.

[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a sliding sleeve is provided at one end of the positioning plate 41, and the positioning plate 41 slides on the side wall of the limiting frame 33 through the sliding sleeve. The limiting nut abuts against the side wall of the limiting frame 33 through the side wall of the sliding sleeve of the positioning plate 41. The width of the positioning plate 41 is smaller than the spacing of the pre-embedded steel bars on the precast bridge cover plate. This facilitates the positioning plate 41 to be positioned on the limiting frame 33 by the limiting nut, and restricts the position of the flipped precast bridge cover plate by the positioning plate 41.

[0026] The working principle of the overturning device for traffic bridge screens provided by this utility model is as follows:

[0027] In use, firstly, the forklift 1 is operated to insert the prefabricated bridge cover plate, so that the thicker end of the prefabricated bridge cover plate abuts against the side wall of the limiting frame 33. Then, the positioning plate 41 is slid downward along the shorter side wall of the limiting frame until it abuts against the surface of the prefabricated bridge cover plate. The position of the positioning plate 41 is fixed on the limiting frame 33 by rotating the limiting nut. Then, the motor 51 is connected to an external power source, so that the motor 51 is driven by the transmission belt 52 and the pulley 53, thereby driving the screw 54 into the slide groove 6. The rotation of the screw 54 causes the support rod 56 to move along with the rotation of the screw 54. Under the support of the support rod 56, the support rod 55 is pushed open. One end of the support rod 55 rotates with the screw 54 through a connector, so that the support rod 55 does not rotate with the screw 54. Under the support of the support rod 56, the support rod 55 pushes open the pad 31, which drives the pad 31 to rotate along the rotating shaft 32 under the support of the support rod 55. This restricts the flipping of the precast bridge cover from the inside, making it easier to inspect the surface of the precast bridge cover.

[0028] Compared with related technologies, the flipping device for traffic bridge screens provided by this utility model has the following advantages:

[0029] This utility model provides a flipping device for a traffic bridge cover. Firstly, a forklift 1 can directly insert a prefabricated bridge cover into the inside of the flipping structure 3. Then, by adjusting the position of the limiting structure 4 on the limiting frame 33, it is made to abut against the prefabricated bridge cover, restricting its position. By connecting the driving structure 5 to an external power source, the support rod 55 and the strut 56 can be extended with the rotation of the screw 54. Thus, the support rod 55, supported by the strut 56, supports the flipping structure 3, causing the flipping structure 3 to rotate on the forklift 1. This causes the prefabricated bridge cover restricted inside the flipping structure 3 to flip, exposing the previously covered sidewalls of the prefabricated bridge cover for easy inspection.

[0030] 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.
