In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 3, the embodiment of the present application provides a collision avoidance apparatus for a multi-pile pier of a bridge in molten iron combined transportation, which includes a buoyancy frame body 1, wherein the buoyancy frame body 1 includes a first connecting rod 10, a second connecting rod 11 and a plurality of partition rod assemblies 12, and the first connecting rod 10 is configured to be disposed on a near-shore side 20 of the pier 2; the second connecting rod 11 is arranged in parallel with the first connecting rod 10 and is arranged on the far bank side 21 of the pier 2; each partition rod assembly 12 is arranged at intervals along the length direction of the first connecting rod 10, each partition rod assembly 12 comprises two partition rods 120 arranged at intervals, two ends of each partition rod 120 are respectively connected with the first connecting rod 10 and the second connecting rod 11, and a buffer space 13 for accommodating the pier 2 is formed by the two partition rods 120 and the first connecting rod 10 and the second connecting rod 11; the anti-collision energy dissipation mechanisms 3 are arranged on the outer side of the second connecting rod 11 at intervals along the length direction of the second connecting rod 11.

Molten iron intermodal aquatic bridge includes many piers, and many piers set up to the interval along indulging the bridge, and every stake pier includes a plurality of piers 2 along the horizontal bridge to setting up. The first connecting rod 10, the second connecting rod 11 and the separating rod assembly 12 are all hollow sealing structures, form a self-floating system and rise and fall simultaneously along with water level change. And all structures of the first connecting rod 10, the second connecting rod 11 and the partition rod assembly 12 are made of steel structures, so that the integral structure is ensured to keep certain rigidity when a ship collides. The first connecting rods 10 are formed by assembling a plurality of rod pieces and are matched with the shapes of the near-shore sides 20 of all the piers 2, and the second connecting rods 11 are matched with the shapes of the far-shore sides 21 of all the piers 2; the first connecting rod 10 and the second connecting rod 11 are connected to each other by the spacer bar assembly 12 to form a whole body, and enclose all piers 2, and two spacer bars 120 arranged at intervals included in the spacer bar assembly 12 enclose one pier 2 of one pile for protection.

Because boats and ships are in the in-process of transporting goods, can strike the far bank side 21 of the pier 2 of aquatic bridge, the pier 2's of single stake self structure list is thin, and anti striking ability is comparatively weak, can't realize single mound and resist and hit. Therefore, the second connecting rod 11 is provided with the anti-collision energy dissipation mechanism 3 facing the ship impact surface; when a ship impacts the second connecting rod 11, the collision energy is absorbed by the anti-collision energy dissipation mechanism 3 in the embodiment of the application, so that the impact force of the ship on the pier 2 is weakened, and the effect of protecting the pier 2 is achieved; and the pier 2 of all the piles are combined to share the impact force to disperse the collision energy.

Optionally, referring to fig. 4, the energy dissipation collision preventing mechanism 3 includes a damping seat 30 and a roller 31, and one end of the damping seat 30 is disposed on the second connecting rod 11; the roller 31 is rotatably disposed on the other end of the damping seat 30.

The roller 31 can change the ship impact direction when the ship impacts, and reduce the impact force. All anti-collision energy dissipation mechanisms 3 are connected into a whole to form a combined anti-collision structure, and surround the pier 2 through the buoyancy frame main body 1, so that the effect of common stress can be achieved when the ship is impacted, and the impact force of the single pier is further reduced.

Alternatively, referring to fig. 4, the second connecting rod 11 includes a box-shaped main body 110 and a plurality of partition plates 111, the partition plates 111 are disposed in the box-shaped main body 110, and the partition plates 111 are spaced apart along a length direction of the box-shaped main body 110 and partition an inner cavity of the box-shaped main body 110 into a plurality of sealed compartments 112.

The box-shaped main body 110 of the second connecting rod 11 forms a plurality of sealed cabins 112 through a plurality of isolation plates 111, and the whole structure can still keep a self-floating working state after the single sealed cabin 112 is damaged by collision. Wherein, the top surface of box main part 110 is provided with the manhole, and the maintainer about the accessible manhole is convenient for anticollision facility's maintenance. And the surface of the box-shaped main body 110 is covered with a composite material, so that the effects of energy dissipation and original structure protection during ship collision are achieved.

Preferably, referring to fig. 5, the energy absorbing and buffering material 113 is filled in the sealed cabin 112.

The energy absorbing and buffering material 113 serves to absorb energy generated by impact when a ship collides with an impact preventing facility, and further attenuate the energy of the collision.

Further, the energy absorbing buffer material 113 is one of elastic gel, high pressure gas and hydraulic oil.

When the energy-absorbing buffer material 113 is an elastic colloid, it can absorb energy by generating elastic potential energy through compression; when the energy-absorbing buffer material 113 is high-pressure gas, the potential energy, the molecular internal energy and the heat energy of the high-pressure gas can be improved by compression to absorb energy; when the energy-absorbing buffer material 113 is hydraulic oil, the sealed cabin 112 needs to be communicated with the liquid storage cavity through a channel with a small cross section, and when the sealed cabin collides, the hydraulic oil is pressed into the liquid storage cavity at a high speed, so that the kinetic energy and the heat of the hydraulic oil are improved to absorb energy.

Optionally, referring to fig. 4 and 5, the anti-collision device further includes a plurality of first damping mechanisms 4, the first damping mechanisms 4 are located in the buffer space 13, one end of each first damping mechanism 4 is disposed at the inner side of the second connecting rod 11, and the other end of each first damping mechanism 4 is configured to face the pier 2, so as to prevent the second connecting rod 11 from colliding with the pier 2.

When boats and ships striking second connecting rod 11, second connecting rod 11 can strike pier 2, and first damping mechanism 4 mainly plays the effect of buffering and reducing the impact force of second connecting rod 11 to the pier.

Preferably, as shown in fig. 4 and 5, the first damping mechanism 4 comprises two first damping elements 40, one end of each of the two first damping elements 40 is spaced apart from the second connecting rod 11, and the other end is configured to face the pier 2 and jointly form an arc shape adapted to the outer surface of the pier 2.

Since the impact force of the ship received by the second connecting rod 11 has no directivity, the impact force from each direction causes the second connecting rod 11 to generate an impact force on the surface of the second connecting rod opposite to the pier 2, and therefore, the outer surfaces of the two first damping elements 40 close to the pier 2 are designed to be arc-shaped to match with the pier 2, so as to resist the impact force of the second connecting rod 11 on the pier 2 from each direction.

Further, as shown in fig. 4, both the first damping elements 40 are disposed obliquely, and the ends of the two first damping elements 40 facing the pier 2 are disposed close to each other.

The two first damping elements 40 are obliquely arranged and are arranged close to each other towards one end of the pier 2, so that the end surfaces of the two first damping elements 40 facing the pier 2 jointly form an arc shape matched with the outer surface of the pier 2.

Optionally, referring to fig. 3, the anti-collision device further includes a plurality of second damping mechanisms 5, the second damping mechanisms 5 are located in the buffer space 13, and each second damping mechanism 5 includes two second damping elements 50, one end of each second damping element 50 is disposed on an opposite inner wall of each of the two separation bars 120 included in the separation bar assembly 12, and the other end of each second damping element is configured to face the bridge pier 2, so as to prevent the separation bar 120 from colliding with the bridge pier 2.

Since the buoyancy frame body 1 is subject to the buoyancy of water, the separation rod 120 may have a certain impact force against the pier 2, and thus the second damping member 50 is designed to withstand the impact force of the separation rod 120 against the pier.

Optionally, referring to fig. 3, the anti-collision device further includes a plurality of third damping mechanisms 6, the third damping mechanisms 6 are located in the buffer space 13, and one end of each third damping mechanism 6 is disposed on the first connecting rod 10, and the other end of each third damping mechanism 6 is configured to face the pier 2, so as to prevent the first connecting rod 10 from colliding with the pier 2.

Because buoyancy frame main part 1 receives the buoyancy of water, first connecting rod 10 also can have certain impact force to pier 2, consequently designs third damping device 6 and withstands the impact force of first connecting rod 10 to the pier, plays the omnidirectional protection to pier 2.

The first damping element 40, the second damping element 50 and the third damping mechanism 6 are all connected with the buoyancy frame main body 1 through connecting bolts and damping pressure plates and are fixed in a bolting mode, and replacement can be facilitated after damage caused by ship collision.
