[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown, this embodiment discloses an automatic lifting device for a transponder bracket, including a mounting frame 1, a beacon mounting plate 2 and an electric drive device 3, a beacon 4 is arranged on the beacon mounting plate 2, a fixed end of the beacon mounting plate 2 is rotatably connected to the mounting frame 1, the electric drive device 3 is fixedly mounted on the mounting frame 1, and an output end of the electric drive device 3 is transmission-connected to the fixed end of the beacon mounting plate 2.

[0020] In order to facilitate the installation of the mounting frame 1, in this embodiment, a hook 5 is provided on the back of the mounting frame 1, and the hook 5 is engaged with the bracket 6; wherein the bracket 6 is an integrally formed plate, and the bracket 6 includes a back plate 601, and the back plate 601 is fixed to the inspection pit foundation 7 by expansion bolts, and the upper and lower edges of the back plate 601 are provided with a folding plate 602 bent toward the mounting frame 1, and a plurality of fixing holes 603 are opened along the length direction of the folding plate 602, and the hook 5 is engaged with the upper folding plate 602, and the mounting frame 1 is abutted against the lower folding plate 602. The mounting hole on the mounting frame 1 is aligned with the fixing hole 603 on the bracket 6, and the hook is fixed by a bolt assembly.

[0021] In this embodiment, the beacon mounting plate 2 includes a flip plate 201, which is made of non-metallic material to avoid electromagnetic interference to the beacon 4. The flip plate 201 is fixed on the flip seat 202, and a rotating shaft 203 is fixed on the flip seat 202. Both ends of the rotating shaft 203 are provided with shaft seats 204, and the shaft seats 204 are fixed on the mounting frame 1. One end of the rotating shaft 203 is connected to the electric drive device 3.

[0022] In this embodiment, two supporting ridges 205 arranged side by side are provided on the flip plate 201, and the beacon 4 is fixed on the two supporting ridges 205. The supporting ridges 205 can elevate the beacon 4, which is convenient for ventilation of the bottom of the beacon 4 and avoids the humid environment affecting the use of the beacon 4.
