Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision devices, in particular to an anti-collision device for a composite material bridge. Background Art

[0002] Usually, when transporting goods, water vehicles may collide or scratch against bridge piers due to errors or other reasons when passing through bridges, causing damage to the piers and affecting their service life. Therefore, after the bridge is built, an anti-collision device is often installed on the piers to prevent damage to the piers.

[0003] At present, in the actual application process, the anti-collision device can buffer the impact force of the ship to reduce the damage to the bridge pier column. However, in the process of use, most of the current anti-collision devices use rubber materials to buffer the impact force of the ship. When the rubber pad avoids contact with the ship, the friction between the rubber pad and the ship will increase, which will make it difficult for the ship to deflect away from the bridge pier column under the action of the impact force. Therefore, the rubber pad needs to buffer all the impact force of the ship. Once the impact force of the ship is large, it is difficult for the rubber pad to absorb all the impact force. Therefore, the remaining force needs to be absorbed by the bridge pier column. In the long run, the bridge pier column will be damaged and the service life of the bridge pier column will be reduced.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-6 The utility model provides an embodiment: a composite material bridge anti-collision device, including a bridge pier column 1, an anti-collision steel structure 2 and a floating airbag 3 are sleeved on the bridge pier column 1, the anti-collision steel structure 2, the floating airbag 3 and the bridge pier column 1 are movably connected, the floating airbag 3 is arranged below the anti-collision steel structure 2 and is fixedly connected thereto, the floating airbag 3 pushes the composite buffer block 4 to always be above the water surface, both ends of the anti-collision steel structure 2 are fixedly connected with the composite buffer block 4, the composite buffer block 4 is used to buffer the impact force, the upper and lower sides of the anti-collision steel structure 2 are fixedly connected with fixed plates 5, a buffer shaft 6 is arranged between the fixed plates 5, the fixed plates 5 are used to fix the buffer shaft 6, both ends of the buffer shaft 6 pass through the fixed plates 5 and are rotatably connected thereto, a plurality of buffer shafts 6 are arranged and are evenly distributed, a rubber sleeve 7 is sleeved on the buffer shaft 6, and the rubber sleeve 7 is fixedly connected to the buffer shaft 6.

[0024] Through the above technical solution, by setting the buffer shaft 6, when the ship collides with the buffer shaft 6 on the pier column 1, the impact force of the ship on the buffer shaft 6 will be converted into a rotational force due to the rotational connection between the buffer shaft 6 and the fixed plate 5, so that the buffer shaft 6 can rotate freely between the fixed plates 5, and the buffer shaft 6 has a flow conductivity under the action of the rotational force. Therefore, under the action of the flow conductivity, after the ship collides, the ship can be diverted forward, and the direction of the ship's impact force can be changed and deflected, so that the ship is away from the pier column 1, so as to decompose the impact force of the ship and achieve the effect of force release. When the ship collides with the buffer shaft 6, the rubber sleeve 7 can be used to perform a preliminary buffering on its impact force.

[0025] Specifically, a protective steel plate 8 is provided on the other side of the composite buffer block 4 , and the protective steel plate 8 is fixedly connected to the composite buffer block 4 .

[0026] Through the above technical scheme, by setting the protective steel plate 8, ships are usually made of iron, and the composite buffer block 4 is mostly composed of rubber and other materials. The protective steel plate 8 can avoid direct friction between the ship and the composite buffer block 4, and the friction between metal and metal is relatively low. Therefore, when the ship collides with the protective steel plate 8, due to the small friction, the impact force of the ship will be converted into a sliding force, causing the ship to slide on the surface of the protective steel plate 8, which will cause the ship to continue to move backwards forward and keep the ship away from the pier 1, so as to decompose the impact force of the ship and avoid damage to the pier 1.

[0027] Specifically, a rubber pad 9 is provided on the inner side of the anti-collision steel structure 2 , and the rubber pad 9 is sleeved on the pier column 1 and movably connected thereto, and a through groove 13 is provided on the rubber pad 9 , and a plurality of through grooves 13 are provided and evenly distributed.

[0028] Through the above technical solution, by setting the rubber pad 9, when the ship collides with the device, the anti-collision steel structure 2 approaches the pier column 1, and the rubber pad 9 can form a soft contact between the pier column 1 and the anti-collision steel structure 2 to buffer the force of the anti-collision steel structure 2 on the pier column 1, thereby avoiding damage to the pier column 1.

[0029] Specifically, a placement groove 10 is opened on the inner side of the anti-collision steel structure 2. There are several placement grooves 10 and they are evenly distributed. The placement grooves 10 correspond to the springs 14. The anti-collision steel structure 2 is slidably connected to a fixed frame 11 inside through the placement grooves 10. The other side of the fixed frame 11 is rotatably connected to a rotating roller 12.

[0030] Through the above technical solution, by setting the fixed frame 11 and the rotating drum 12, when the water level rises or falls, the rotating drum 12 can be made to roll on the surface of the pier column 1 to avoid the rubber pads 9 on the inner side of the anti-collision steel structure 2 from contacting the pier column 1. Since the friction between the rubber pads 9 and the pier column 1 is large when they contact, it is very easy to cause the device to be unable to float up or fall due to the friction. Therefore, the rotating drum 12 can effectively prevent this from happening.

[0031] Specifically, the anti-collision steel structure 2 is provided with a spring 14 inside through the placement groove 10. The spring 14 is arranged on one side of the fixed frame 11. One end of the spring 14 is fixedly connected to the inner wall of the anti-collision steel structure 2, and the other end of the spring 14 is fixedly connected to one side of the fixed frame 11. The rotating drum 12 on the other side of the fixed frame 11 is in conflict with the surface of the pier column 1 through the action force of the spring 14.

[0032] Through the above technical scheme, by setting the spring 14, under the action of the spring 14, the fixed frame 11 can be pushed, so that the rotating drum 12 always contacts the surface of the pier column 1, and the springs 14 and the rotating drum 12 are set around the inner side of the anti-collision steel structure 2, so that the rubber pad 9 inside the anti-collision steel structure 2 can always maintain an appropriate distance from the pier column 1, so as to effectively avoid the friction between the rubber pad 9 and the pier column 1. At the same time, when the ship collides, the spring 14 will be indirectly compressed, so that the rotating drum 12 and the fixed frame 11 will retract to the inside of the anti-collision steel structure 2, and the rubber pad 9 can contact with the pier column 1 to buffer the impact force.

[0033] Specifically, both ends of the composite buffer block 4 are configured as arc-shaped surfaces, and both ends of the protective steel plate 8 are configured as arc-shaped surfaces.

[0034] Through the above technical scheme and the above settings, when the ship collides with the buffer shaft 6, the buffer shaft 6 will divert and release force on the ship. When the buffer shaft 6 diverts the ship to the connection between the buffer shaft 6 and the protective steel plate 8, the ship can be well transitionally diverted through the arc surface, so that the ship will not directly conflict with the connection between the protective steel plate 8 and the buffer shaft 6.

[0035] Working principle: When in use, when the water level rises or falls, the floating airbag 3 will push the anti-collision steel structure 2 to rise and fall, and under the action of the rotating drum 12, the device can rise or fall smoothly. When the ship collides with the buffer shaft 6 on the pier 1, the impact force of the ship on the buffer shaft 6 will be converted into a rotational force due to the rotational connection between the buffer shaft 6 and the fixed plate 5, so that the buffer shaft 6 can rotate freely between the fixed plates 5, and the buffer shaft 6 has flow conductivity under the action of the rotational force. Therefore, under the action of the flow conductivity, after the ship collides, the ship can be diverted forward, the direction of the ship's impact force can be changed and deflected, and the ship can be moved away from the pier 1, so as to decompose the impact force of the ship and achieve the effect of force release. When the ship collides with the protective steel plate 8 outside the composite buffer block 4, the protective steel plate 8 can prevent the ship from There is direct friction between the ship and the composite buffer block 4, while the friction between metal and metal is relatively low. Therefore, when the ship collides with the protective steel plate 8, due to the small friction, the impact force of the ship is converted into a sliding force, causing the ship to slide on the surface of the protective steel plate 8, which will cause the ship to continue to move backwards forward, change the direction of the ship's impact force, and deflect the ship away from the pier column 1, so as to release the impact force of the ship and avoid damage to the pier column 1. At the same time, when the device is hit, the anti-collision steel structure 2 approaches the pier column 1. At this time, the spring 14 will be indirectly compressed, causing the rotating drum 12 and the fixed frame 11 to retract into the inside of the anti-collision steel structure 2, and the rubber pad 9 can fit between the pier column 1, so that the pier column 1 and the anti-collision steel structure 2 form a soft contact, so as to buffer the force of the anti-collision steel structure 2 on the pier column 1, so as to avoid damage to the pier column 1.
