Description

Technical Field

[0001] The present application relates to the field of bridge piers, and in particular to an anti-collision bridge pier. Background Art

[0002] At present, in order to protect bridge piers, pier protection devices are generally installed on the piers.

[0003] In related technologies, protective devices generally use soft devices (such as airbags, air cushions, etc.), which are wrapped around the bridge piers. When the bridge piers are hit, the soft devices can play a certain buffering role to prevent the bridge piers from being damaged.

[0004] Regarding the above-mentioned related technologies, when a ship hits a bridge pier, although the software device can play a certain buffering role, once the ship is moving at a faster speed, the software device cannot completely offset the kinetic energy generated when the ship hits the bridge pier, and the ship will still cause significant damage to the bridge pier. Summary of the Invention

[0005] In order to facilitate improving the protective effect of software devices on bridge piers, the present application provides an anti-collision bridge pier.

[0008] By adopting the above technical solution, when a ship is about to hit the pier, the mounting plate is driven to rotate by the driving assembly, thereby driving the air cushion to rotate. By judging the impact direction of the ship, the mounting plate is controlled to rotate forward or reverse. Therefore, when the ship hits the air cushion, the rotation of the air cushion can bring a certain tangential force to the ship, thereby driving the ship to rotate, so that after the ship hits the air cushion, the direction of the ship can be changed, thereby avoiding damage to the ship and the pier. By utilizing the rotation of the air cushion, on the one hand, the air cushion can play a certain buffering role, and on the other hand, the rotation of the air cushion can drive the ship to rotate, so that the ship changes the impact direction, thereby avoiding damage to the ship and the pier, thereby improving the protective effect of the air cushion on the bridge pier.

[0009] Optionally, the driving assembly includes a ring gear, a gear and a motor 1, the ring gear is coaxially connected to the pier body, the gear is rotatably connected to the pier body, and the gear and the ring gear are meshingly connected, the motor 1 is used to drive the ring gear to rotate, a connecting rod is fixedly connected to the ring gear, and the mounting plate is installed on the connecting rod and can follow the movement of the connecting rod.

[0010] By adopting the above technical solution, when driving the mounting plate to rotate, the motor 1 is turned on to drive the gear to rotate, thereby driving the ring gear to rotate, and the rotation of the ring gear drives the mounting plate to rotate; the driving component has a simple structure and is easy to operate.

[0014] By adopting the above technical solution, when the two connecting blocks are spliced ​​together to form the mounting ring, the insertion rod is inserted into the slot, and the arc-shaped convex surface of the card block decomposes the force exerted on the card block into the force of completely inserting into the makeshift slot. Until the card block moves to the card slot position, the card block is reset under the action of spring 1 and partially inserted into the card slot, thereby splicing the two connecting blocks into the mounting ring. The connection assembly has a simple structure and is easy to operate. When the mounting plate needs to be removed, the card block can be removed from the card slot by unlocking the assembly.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] An embodiment of the present application discloses an anti-collision bridge pier.

[0034] Reference Figure 1 and Figure 2 A collision-proof bridge pier includes a pier body 1 and a plurality of protective devices 2 arranged on the pier body 1. In the present application, the pier body 1 is cylindrical, the protective devices 2 are annular and sleeved on the pier body 1, and the plurality of protective devices 2 are sequentially arranged close to each other along the height direction of the pier body 1.

[0035] Reference Figure 2 and Figure 3 The protective device 2 includes a mounting plate 3 and an air cushion 4. The mounting plate 3 and the air cushion 4 are both sleeved on the pier body 1. The air cushion 4 is fixed on the side of the mounting plate 3 away from the pier body 1.

[0036] The mounting plate 3 can rotate coaxially around the pier body 1 , and a driving assembly for driving the mounting plate 3 to rotate is provided on the pier body 1 .

[0037] The upper end of the pier body 1 is fixedly connected to a fence 5, and the driving assembly includes a ring gear 6, a gear 7 and a motor 8. The ring gear 6 is coaxially connected to the upper end of the pier body 1, and the ring gear 6 can also be rotatably connected to the fence 5. The motor 8 is fixedly connected to the fence 5, and the output shaft of the motor 8 is coaxially fixedly connected to the gear 7. The gear 7 and the ring gear 6 are meshed and connected;

[0038] A connecting rod 9 is fixedly connected to the gear ring 6. The length direction of the connecting rod 9 is arranged along the height direction of the pier body 1. The connecting rod 9 is located on the outside of the pier body 1. A mounting ring 10 is provided on the mounting plate 3. The mounting ring 10 is sleeved on the connecting rod 9. In this embodiment, there are two connecting rods 9 and two mounting rings 10.

[0039] In this embodiment, the number of motor 1 8 and the number of gears 7 are both four, and the four gears 7 are equidistantly arranged.

[0040] In another embodiment, the driving component can also be a walking wheel, which is installed on the connecting rod 9. The walking wheel moves around the pier body 1 and is driven by the motor 8 to rotate, thereby driving the rotation of the connecting rod 9 and thereby realizing the rotation of the protective device 2.

[0041] In this embodiment, a radar and a processor are installed on the fence 5. The radar can scan the height information of the ship and transmit the information to the processor. The processor determines the impact position of the ship on the pier 1 based on the information and generates an early warning strategy. The strategy is implemented by motor 8 (the protection device 2 is driven forward or reverse by motor 8 to adapt to the impact position of the ship) to deviate the ship and thereby protect the pier 1.

[0042] In order to facilitate the replacement of a damaged protective device 2, the protective device 2 is set as two unit sections, and the two unit sections are spliced ​​into a protective device 2. The mounting plate 3 and the air cushion 4 are both semicircular arc-shaped, and the air cushion 4 is fitted and fixed on the inner wall of the mounting plate 3. A mounting plate 3 and an air cushion 4 constitute a unit section, and both ends of the inner wall of the mounting plate 3 in the length direction are fixedly connected with connecting blocks 11. When the two unit sections are spliced ​​to form the protective device 2, the two connecting blocks 11 at the adjacent ends of the two mounting plates 3 are spliced ​​into a mounting ring 10, and the two connecting blocks 11 are fixed by a connecting assembly so that the mounting ring 10 can be stably mounted on the connecting rod 9.

[0043] In the two connecting blocks 11 at one end adjacent to the two mounting plates 3, the two connecting blocks 11 are fixedly connected to the plug rod 12, and the two connecting blocks 11 are provided with a slot 13 for the plug rod 12 to be inserted, that is, the plug rod 12 on one connecting block 11 can be inserted into the slot 13 of the other connecting block 11; the connecting assembly is provided on the plug rod 12, and each plug rod 12 is provided with a connecting assembly, the connecting assembly includes a spring 14 and a card block 15, the plug rod 12 is provided with a makeshift groove 17 for the card block 15 to be fully inserted, and the spring Spring 14 is fixed in the give way groove 17, and the length direction of spring 14 is arranged along the plug-in direction of block 15. Spring 14 and block 15 are fixedly connected. When spring 14 is not deformed, part of block 15 is located outside the give way groove 17, and the part of the side wall of block 15 facing away from the notch of slot 13 located outside the give way groove 17 is an arc-shaped convex surface; a slot 16 for inserting block 15 is provided on the inner wall of slot 13; an unlocking component for driving block 15 out of slot 16 is provided on connecting block 11.

[0044] In another embodiment, the connecting assembly can use screws to fix the two connecting blocks 11; however, there are some disadvantages in fixing with screws, the main reason being: when the connecting block 11 is located on the side of the mounting plate 3 away from the pier body 1, it is easy to be hit by a ship, resulting in a rigid collision; and when the connecting block 11 is located on the side of the mounting plate 3 close to the pier body 1, since the present application uses multiple protective devices 2, when the middle protective device 2 needs to be replaced, due to limited operating space, it is inconvenient to remove the screws to replace the mounting plate 3; therefore, the present application adopts a locking method of the card block 15 as in the present embodiment.

[0045] In this embodiment, the unlocking assembly includes a piston rod 18, an air groove 34 is provided on the connecting block 11, the piston rod 18 can move in the air groove 34, and the piston rod 18 and the inner wall of the air groove 34 are sealed; the air groove 34 is connected to the card slot 16 through the air channel 21, and the card slot 16 is provided with a piston plate 20 that can move in the card slot 16, and the piston plate 20 and the inner wall of the card slot 16 are sealed. The piston rod 18 moves to push the piston plate 20 to move, and the movement of the piston plate 20 can push the card block 15 out of the card slot 16; a spring 2 19 is fixedly connected to the air groove 34, and the spring 2 19 is fixedly connected to the piston rod 18. The spring 2 19 is not When deformed, part of the piston rod 18 is located outside the air groove 34; a strip groove 23 is opened on the connecting rod 9 in the vertical direction, and both ends of the connecting rod 9 in the length direction are not penetrated by the strip groove 23. A guide rod 24 is fixedly connected in the strip groove 23, and the length direction of the guide rod 24 is arranged in the vertical direction. An air bag 27 is sleeved and fixedly connected to the guide rod 24. One end of the piston rod 18 extending out of the air groove 34 is fixedly connected to a splint 22. The splint 22 is an arc shape that matches the outer wall of the guide rod 24. The inner wall of the splint 22 abuts against the air bag 27. An air pump 25 is fixedly connected to the ring gear 6, and the air outlet of the air pump 25 is connected to the air bag 27 through the trachea 26.

[0046] When the two connecting blocks 11 need to be separated, the air pump 25 is turned on to inflate the airbag 27. The expansion of the airbag 27 pushes the piston rod 18 to move, thereby pushing the gas in the air groove 34 into the card slot 16. Under the action of air pressure, the piston plate 20 moves to push the card block 15 out of the card slot 16, thereby unlocking the two connecting blocks 11 and separating the two connecting blocks 11.

[0047] In another embodiment, the unlocking component can also use an electric push rod, which is fixed on the connecting block 11. An opening connected to the card slot 16 is opened on the connecting block 11. The telescopic end of the electric push rod can be inserted into the card slot 16 through the opening to push out the card block 15 in the card slot 16; however, there are some disadvantages in unlocking by using an electric push rod. The main reasons are: the electric push rod needs to be used for a long time and the battery needs to be replaced. It is still inconvenient to take it out due to limited operating space. In addition, the size of the electric push rod needs to be very small, and it is difficult to find a suitable model on the market; therefore, this application adopts an inflatable unlocking method as in the present embodiment.

[0048] Reference Figure 1 and Figure 3 In this embodiment, due to the setting of the strip groove 23 and the ability of the mounting ring 10 to be stably mounted on the connecting rod 9, multiple protection devices 2 can simultaneously move along the height direction of the pier body 1. In order to facilitate the movement of multiple protection devices 2 along the height direction of the pier body 1, a support block 28 is mounted on the connecting rod 9. The upper surface of the support block 28 abuts against the mounting plate 3 of the protection device 2 located at the bottom, and a driving mechanism for driving the support block 28 to move is provided on the pier body 1.

[0049] The driving mechanism includes a second motor 30 and a winding roller 29. The winding roller 29 is rotatably connected to the ring gear 6. The second motor 30 is fixedly connected to the ring gear 6. The output shaft of the second motor 30 is coaxially fixedly connected to the winding roller 29. A pull rope 32 is wound and fixedly connected to the winding roller 29. The pull rope 32 is fixedly connected to the support block 28.

[0050] In another embodiment, the driving mechanism may further include a fixed pulley 31, which is fixed at the lower end of the connecting rod 9. Two pull ropes 32 are wound and fixedly connected to the winding roller 29. The winding directions of the two pull ropes 32 are opposite. One of the pull ropes 32 is directly fixedly connected to the upper surface of the support block 28, and the other pull rope 32 passes around the fixed pulley 31 and is fixedly connected to the lower surface of the support block 28. Through the arrangement of the pull rope 32 and the support block 28, a supporting force can be provided to the connecting rod 9 to ensure the stability of the connecting rod 9.

[0051] Reference Figure 4In another embodiment, in order to enable the inflatable protective device 2 to overcome the buoyancy of water and descend into the water to protect the underwater pier body 1, a straight rod 35 is threadedly connected to the support block 28, and the straight rod 35 simultaneously passes through multiple mounting plates 3 and is threadedly connected to the support block 28 in the vertical direction, and an enlarged portion 36 is fixedly connected to the upper end of the straight rod 35, and multiple mounting plates 3 are confined between the enlarged portion 36 and the support block 28; and the threaded connection between the support block 28 and the straight rod 35 ensures that the straight rod 35 can be removed to replace the protective device 2.

[0052] In this embodiment, the radar can also scan the height information of the ship, and transmit the information to the processor. The processor determines the impact height of the ship hitting the pier 1 based on the information, generates an early warning strategy, and implements the strategy through motor 2 30 (by driving the protection device 2 up or down through motor 2 30 to adapt to the impact position of the ship) to protect the pier 1.

[0053] In this embodiment, a plurality of rubber blocks 33 are fixedly connected to the inner wall of the mounting plate 3 , and the rubber blocks 33 abut against the outer wall of the pier body 1 .

[0054] The implementation principle of an anti-collision pier in an embodiment of the present application is as follows: after a ship enters the radar scanning range, the radar scans the position information and height information of the ship and transmits the information to the processor. The processor determines the impact position and impact height of the ship hitting the pier body 1 based on the information, generates an early warning strategy, and implements the strategy through motor 1 8 and motor 2 30. The implementation process is as follows: the gear 7 is driven to rotate by motor 1 8, thereby driving the ring gear 6 to rotate. The rotation of the ring gear 6 drives the mounting plate 3 to rotate through the connecting rod 9 to apply a tangential force to the ship, causing the ship to deflect. , preventing the ship from continuing to collide with the pier body 1; the motor 2 30 drives the winding roller 29 to rotate, thereby adjusting the height of the protection device 2, so that the protection device 2 is located at the ship collision position, so as to protect the pier body 1; and when a certain protection device 2 is damaged, the air pump 25 is turned on to inflate the airbag 27, the airbag 27 expands and pushes the piston rod 18 to move, and under the action of air pressure, the piston plate 20 is driven to move, and the piston plate 20 moves to push the card block 15 in the card slot 16 out, so that the two connecting blocks 11 can be separated, so that the damaged protection device 2 can be removed.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
