Specific embodiments

[0025] Please refer to Figures 1 - 7 , a warning highway bridge anti-collision device, including an anti-collision mechanism 100 and an installation mechanism 200 arranged on the rear side thereof. The anti-collision mechanism 100 includes an installation shell 101:

[0026] Furthermore, a first anti-collision plate 102 is provided on the front side of the installation shell 101. An installation groove 103 is opened at the center of the front side surface of the installation shell 101. Both left and right ends of the rear side of the first anti-collision plate 102 are rotatably connected to a rotating rod 104. One end of the rotating rod 104 away from the first anti-collision plate 102 is rotatably connected to a moving block 105. The inner wall of the moving block 105 is slidably connected to a fixed rod 106. The fixed rod 106 is fixedly installed inside the installation groove 103. Both left and right ends of the surface of the fixed rod 106 are movably sleeved with a first spring 107. One end of the first spring 107 is fixedly connected to the moving block 105, and the other end of the first spring 107 is fixedly connected to the inner wall of the installation groove 103.

[0027] When an object (such as a vehicle) impacts the first anti-collision plate 102, the plate will move backward, driving the rotating rod 104 to rotate, and then causing the moving block 105 to slide along the fixed rod 106. At this time, the first spring 107 will be compressed to store energy. Once the collision ends, the first spring 107 releases energy, pushing the moving block 105 back to its original position, thereby driving the first anti-collision plate 102 to reset.

[0028] Further, extension plates 108 are slidably connected to both the left and right sides of the mounting shell 101. A second anti-collision plate 109 is slidably connected to the inner wall of the front side of the extension plate 108. A plurality of elastic members 110 are fixedly connected between the extension plate 108 and the second anti-collision plate 109 at equal intervals.

[0029] There is one extension plate 108 on each of the left and right sides of the mounting shell 101, which is slidably connected to the mounting shell 101 and can be telescoped. The second anti-collision plate 109 is located in front of the extension plate 108 as the second layer of protection to further absorb the collision energy. A plurality of elastic members 110 arranged at equal intervals between the extension plate 108 and the second anti-collision plate 109 are used to buffer the movement of the second anti-collision plate 109 and absorb energy.

[0030] Further, the elastic member 110 includes a plurality of telescopic rods 111 fixedly arranged at equal intervals on the rear side of the second anti-collision plate 109. A fixing sleeve 112 is slidably connected to the surface of the plurality of telescopic rods 111. The plurality of fixing sleeves 112 are fixedly arranged on the front side of the inner wall of the extension plate 108. A second spring 113 is fixedly connected between the telescopic rod 111 and the fixing sleeve 112.

[0031] Through the combination of the first anti-collision plate 102 and the second anti-collision plate 109, and the double buffering of the first spring 107 and the second spring 113, the collision energy of different intensities can be absorbed more effectively.

[0032] Reflective strips are pasted on the front sides of both the first anti-collision plate 102 and the second anti-collision plate 109. When a vehicle or a ship approaches the bridge, the reflective strips will reflect light under the illumination of the vehicle lights or other light sources, thereby attracting the attention of the driver or the crew. The reflective strips improve the visibility of the device, help to give an early warning, and reduce the probability of accidents.

[0033] Further, sliding grooves 114 are formed in both the top and bottom of the inner wall of the mounting shell 101. Sliders 115 are fixedly connected to both the top and bottom of the side of the extension plate 108 close to the mounting shell 101. The sliders 115 are slidably connected to the sliding grooves 114.

[0034] By forming the sliding grooves 114 in both the top and bottom of the inner wall of the mounting shell 101 and fixedly connecting the sliders 115 to the extension plate 108, this design ensures the stability and smoothness of the extension plate 108 during the sliding process.

[0035] Further, a bidirectional threaded rod 116 is rotatably connected to the upper part inside the mounting shell 101. Threaded sleeves 117 are threadedly connected to both the left and right sides of the surface of the bidirectional threaded rod 116. The mutually remote ends of the threaded sleeves 117 are fixedly connected to the mutually close sides of the extension plates 108.

[0036] By rotating the bidirectional threaded rod 116, the threaded sleeve 117 will move in opposite directions along the threaded rod. Since the threaded sleeve 117 is fixedly connected to the extension plate 108, the extension plate 108 will also move in opposite directions accordingly, achieving telescopic adjustment.

[0037] Furthermore, a worm gear 118 is fixedly sleeved on the surface of the bidirectional threaded rod 116. A worm 119 is meshed and connected to the top of the worm gear 118. The rear side surface of the mounting shell 101 is fixedly connected with a first motor 120. The output end of the first motor 120 extends into the mounting shell 101 and is fixedly connected to the inner wall of the worm 119. A first protective cover 121 is arranged outside the first motor 120. One side of the first protective cover 121 is fixedly connected to the rear side surface of the mounting shell 101.

[0038] When the first motor 120 is started, its output end drives the worm 119 to rotate. Through the meshing action with the worm gear 118, the worm gear 118 is driven to rotate. The worm gear 118 drives the bidirectional threaded rod 116 to rotate, so that the threaded sleeve 117 moves in opposite directions along the bidirectional threaded rod 116. Since the threaded sleeve 117 is fixedly connected to the extension plate 108, the extension plate 108 also moves in opposite directions accordingly, achieving telescopic adjustment. This design enables the extension plate 108 to be accurately adjusted automatically as needed.

[0039] Furthermore, the installation mechanism 200 includes a fixing plate 201 fixedly arranged at the bottom of the rear side of the mounting shell 101. A lifting plate 202 is slidably connected above the fixing plate 201. A slot 203 is formed on the lifting plate 202. The first protective cover 121 is slidably connected to the inner wall of the slot 203. A plurality of mounting plates 204 are fixedly connected to the sides of the fixing plate 201 and the lifting plate 202 away from the mounting shell 101. A plurality of mounting bolts 205 for installing the device on the highway bridge are threadedly connected to the plurality of mounting plates 204.

[0040] By sliding the lifting plate 202 on the fixing plate 201, the height of the entire anti-collision device can be adjusted. The design of the slot 203 ensures that the lifting plate 202 will not be affected by the first protective cover 121. The anti-collision device is fixed to the bridge through the mounting bolts 205 on the mounting plates 204 to ensure the stability of the device. By arranging the fixing plate 201 at the bottom of the rear side of the mounting shell 101 and through the design of the lifting plate 202 and the mounting plates 204, the entire anti-collision device can be conveniently installed on the highway bridge and the height can be adjusted according to the actual situation.

[0041] Further, a lifting screw rod 206 is threadedly connected to the inner wall of one side of the lifting plate 202. The bottom of the lifting screw rod 206 extends below the fixing plate 201 and is fixedly sleeved with a bevel gear ring 207. The top of one side of the bevel gear ring 207 is meshed and connected with a bevel gear 208. The bottom of the mounting shell 101 is fixedly connected with a second motor 209. The output end of the second motor 209 is fixedly connected to the inner wall of the bevel gear 208. A second protective cover 210 is arranged outside the second motor 209. The top of the second protective cover 210 is fixedly connected to the bottom of the mounting shell 101. A limiting rod 211 is slidably connected to the inner wall of the other side of the lifting plate 202. The bottom of the limiting rod 211 is fixedly connected to the top of the fixing plate 201.

[0042] When the second motor 209 is started, its output end drives the bevel gear 208 to rotate. Through the meshing action with the bevel gear ring 207, the bevel gear 208 makes the bevel gear ring 207 rotate. The bevel gear ring 207 drives the lifting screw rod 206 to rotate. The rotation of the lifting screw rod 206 makes the lifting plate 202 move up and down along the lifting screw rod 206, thereby realizing the height adjustment of the entire anti-collision device. The design of the limiting rod 211 ensures that the lifting plate 202 will not tilt or deviate during the lifting process, guaranteeing the stability of its vertical movement.

[0043] By arranging the fixing plate 201 at the bottom of the rear side of the mounting shell 101 and through the design of the lifting plate 202, the lifting screw rod 206, the bevel gear ring 207, the bevel gear 208 and the second motor 209, the entire anti-collision device can be conveniently installed on the highway bridge and can automatically adjust the height according to the actual situation. Combined with the use of the reflective strips and other energy absorption mechanisms, this anti-collision device not only improves the visibility and safety but also can effectively absorb the collision energy and protect the bridge structure from damage.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
