DETAILED DESCRIPTION

[0025] like Figure 1-2 As shown, a civil air defense door frame flipping device includes a base 1, a reinforcement frame 2 fixedly arranged on the top of the base 1, and a counterweight block 3 fixedly arranged on the top of the base 1, and also includes a lifting assembly arranged above the base 1, a flipping assembly arranged above the lifting assembly and a positioning assembly arranged on one side of the flipping assembly. The lifting assembly includes a square frame 4 that moves in the up and down directions, the flipping assembly includes a rotating shaft 5 for rotation and a plug rod 6 for transverse movement, and the positioning assembly includes a positioning frame 7 fixedly arranged at one end of the rotating shaft 5, a pressure plate 8 that moves up and down, and a clamping plate 9 that moves transversely.

[0026] like Figure 1-5 As shown, in order to facilitate the flipping and installation of the civil air defense door frame, the lifting assembly also includes a hydraulic rod 10 that passes through the reinforcement frame 2 and is fixed on the top of the base 1 and the reinforcement frame 2, and a guide rod 11 that is fixed on the bottom wall of the frame 4. The frame 4 is fixed at the upper end of the hydraulic rod 10, and the lower end of the guide rod 11 passes through the reinforcement frame 2 and is slidably connected to the reinforcement frame 2. The guide rods 11 are symmetrically arranged to achieve a stable lifting effect.

[0027] like Figure 1-5As shown, in order to be able to stably rotate and position the civil air defense door frame when needed, the flip assembly includes a worm gear 12 fixedly mounted on the rotating shaft 5, a servo motor 13 fixedly mounted on the outer wall of the frame 4, a worm 14 fixedly mounted at the output end of the servo motor 13, an electric push rod 15 fixedly mounted on the inner wall of the frame 4, a connecting plate 16 fixedly mounted at one end of the electric push rod 15, a round block 17 fixedly mounted at the middle position of the insertion rod 6, and a disc 18 fixedly mounted at one end of the rotating shaft 5. The rotating shaft 5 passes through one side of the frame 4 and is rotatably connected to the frame 4. The worm 14 and the worm gear 12 are meshed with each other. The insertion rod 6 is fixedly mounted on the outer wall of the connecting plate 16. The insertion rod 6 is symmetrically arranged. Positioning holes 19 are provided on the disc 18. The positioning holes 19 are arranged in a ring shape. The positioning holes 19 are adapted to the insertion rod 6. The diameter of the round block 17 is larger than the diameter of the positioning holes 19, thereby improving the installation efficiency of the civil air defense door frame.

[0028] like Figure 1-5 As shown, in order to quickly complete the positioning processing of the civil air defense door frame, the positioning assembly includes a cylinder 20 that passes through the positioning frame 7 and is fixedly connected to the positioning frame 7, a base frame 21 fixedly arranged on the bottom wall of the positioning frame 7, a linear guide rail 22 installed on the top wall of the base frame 21, and a slider 23 slidably arranged on the linear guide rail 22. The positioning frame 7 is arranged in a C shape, and a stroke hole 24 is provided on one side of the bottom of the positioning frame 7. The upper end of the slider 23 passes through the stroke hole 24 and slides in the stroke hole 24. The clamp 9 is fixedly arranged on the top wall of the slider 23, and the pressure plate 8 is fixedly arranged at the lower end of the cylinder 20, which is suitable for civil air defense door frames of different sizes.

[0030] The clamping plate 9 and the pressing plate 8 are both arranged in a concave shape, and a positioning groove 25 is arranged on the inner wall of the positioning frame 7 .

[0031] During specific use, the hydraulic rod 10 is controlled to retract to an appropriate height. During the adjustment process, the guide rod 11 slides on the reinforcement frame 2 to ensure stability during the adjustment process. Then the civil air defense door frame is placed inside the positioning groove 25, and the linear guide rail 22 is controlled to make the slider 23 drive the clamping plate 9 to move laterally. The clamping plate 9 clamps and fixes the side wall of the civil air defense door frame. When the clamping plate 9 moves, the limit block 26 slides on the positioning frame 7 to increase the stability of the clamping plate 9. Then the cylinder 20 is controlled to extend to make the pressure plate 8 move down to clamp and fix the top wall of the civil air defense door frame. Through the above operation, civil air defense door frames of different sizes can be clamped and positioned. If the civil air defense door frame needs to be flipped and adjusted, the servo motor 13 is turned on, and the worm 14 drives the worm wheel 12 to rotate the shaft 5, and the civil air defense door frame performs a stable slow rotation motion. After flipping and adjustment, the electric push rod 15 is controlled to extend, and the insertion rod 6 is inserted into the positioning hole 19 until the round block 17 contacts the disc 18 to prevent the shaft 5 from rotating again.
