Description

Technical Field

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

[0002] As we all know, a bridge generally refers to a structure built across rivers, lakes, or seas to facilitate the passage of vehicles and pedestrians. To adapt to the rapid development of modern transportation, bridges have also been extended to refer to structures built across mountain streams, over unfavorable geological conditions, or to meet other transportation needs to facilitate passage. Ships often travel through rivers, and to prevent direct impact and damage to bridge piers, composite bridge anti-collision devices are installed on the piers to cushion the impact.

[0003] In real life, the existing anti-collision devices for navigation bridges mostly use steel structure casings around the abutments or piers. The energy dissipation facility uses the plastic deformation and damage of steel to dissipate energy. When a ship hits the steel casing anti-collision device, the non-continuous (intermittent) structural steel plates on the outer layer of the anti-collision structure undergo large deformation, absorbing part of the collision energy and prolonging the contact time, so that the peak impact force is reduced. At the same time, due to structural deformation and interaction, the direction of the bow is adjusted, reducing the energy exchange between the ship and the structure. However, when the hull hits the steel casing, the steel casing and the hull produce planar friction, and the direction of the bow is changed through deformation. This method of changing the direction of the bow is not very effective and can easily lead to high damage to the impacted part. In addition, the steel casing is deformed after the impact, which is not convenient to disassemble and repair separately. Therefore, its practicality is not very good and there is room for improvement. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides a composite material bridge anti-collision device, which has the characteristic of improving practicality.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a composite material bridge anti-collision device, comprising a pier body, the lower part of the pier body being wrapped with several protective shells for protecting the pier body, several first mounting holes being provided on the lower parts of the protective shells, and all being plugged into connecting rods, several connecting rods being rotatably connected with rollers through rotating shafts for dispersing impact force, several first threaded holes being provided on the lower parts of the protective shells, and first bolts being threaded into the lower parts of several first bolts, and covers being threaded into the lower parts of several covering covers for covering the lower part of the protective shells, several second mounting holes being provided on the upper parts of the covers, and all being plugged into the corresponding connecting rods for facilitating disassembly and installation of the connecting rods.

[0008] Furthermore, the plurality of connecting rods are arranged in an array, so that the rollers installed on the connecting rods are arranged in an array, and the outer walls of the plurality of rollers are in contact with each other, so that the plurality of rollers can contact each other and disperse the impact force.

[0009] Furthermore, one end of the several protective shells is provided with a card slot, and the other end of the several protective shells is provided with a card plate, and the several protective shells are installed together by inserting the card plate into the card slot.

[0010] Furthermore, several fixing plates are respectively provided on the upper and lower sides of the protective shells, and several fixing plates are each provided with a second threaded hole and are each threadedly connected with a second bolt.

[0012] Preferably, the exteriors of several of the first bolts and the second bolts are coated with an anti-corrosion coating to improve the anti-corrosion effect.

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the present invention provides a composite material bridge anti-collision device with the following beneficial effects:

[0015] The composite bridge anti-collision device has a structure in which when the hull hits the roller on a certain connecting rod, the roller rotates, and the rotation improves the effect of changing the direction of the hull. After changing the direction, it hits the roller next to it, avoiding the impact force being concentrated on a single connecting rod. The multiple rollers drive the other rollers to rotate during the rotation, and the impact force is dispersed to the other rollers in an array. The impact force is dispersed by the rotation of the rollers, and the damage to the impacted part is reduced. At the same time, the threaded connection between the first bolt and the first threaded hole facilitates the removal of the cover from the protective shell, and then the damaged connecting rod and roller are pulled out from the first mounting hole of the protective shell, and can be replaced with new ones for reuse. The removed connecting rod and roller can be repaired separately, thereby improving practicality to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model discloses a composite material bridge anti-collision device, comprising a pier body 1. The lower part of the pier body 1 is wrapped with several protective shells 2, which are used to protect the pier body 1 and prevent the impact force of the hull from damaging the pier body 1. The lower parts of the several protective shells 2 are provided with several first mounting holes, and are all plugged and connected with connecting rods 3. The several connecting rods 3 are all rotatably connected with rollers 4 through rotating shafts. When the hull hits the rollers 4, the rollers 4 rotate under the action of the impact force and transmit the impact force to other contacting rollers 4, squeezing the other rollers. 4 rotates to disperse the impact force and protect the pier body 1. The lower parts of the several protective shells 2 are each provided with a first threaded hole, and are each threadedly connected with a first bolt 5. The lower parts of the several first bolts 5 are each threadedly connected with a blocking cover 6, which is used to cover the lower part of the protective shell 2 to prevent the connecting rod 3 and other devices from falling off. The upper parts of the several blocking covers 6 are each provided with a plurality of second mounting holes 7, and are each plug-in arranged with the corresponding connecting rod 3. The connecting rod 3 is plugged into the first mounting hole and the second mounting hole 7 for installation, which is convenient for disassembly and installation of a single connecting rod 3.

[0025] Several connecting rods 3 are arranged in an array, so that the rollers 4 installed on the connecting rods 3 are arranged in an array. The outer walls of several rollers 4 are in contact with each other, so that multiple rollers 4 are in contact with each other. When a roller 4 is hit by the hull, the roller 4 can transfer the impact force to other rollers 4 through the array. At the same time, the roller 4 rotates under the impact of the impact force to disperse the impact force.

[0026] One end of several protective shells 2 is provided with a card slot 8, and the other end of several protective shells 2 is provided with a card plate 9. The card plates 9 and card slots 8 of several protective shells 2 that cooperate with each other are clamped together. Through the clamping setting of the card plates 9 and the card slots 8, the stability between the protective shells 2 that cooperate with each other can be improved. During installation, the card plate 9 is clamped into the card slot 8, and the protective shells 2 that cooperate with each other can be preliminarily installed on the pier body 1.

[0027] Several protective shells 2 are respectively provided with fixing plates 10 on the upper and lower sides. Several fixing plates 10 are all provided with second threaded holes and are all threadedly connected with second bolts 11. When several protective shells 2 that match each other are initially installed on the pier body 1, several fixing plates 10 are fitted together. At this time, the second bolts 11 are screwed into the second threaded holes of the several fixing plates 10, and the several protective shells 2 that match each other can be installed for the second time, thereby fixing them as a whole.

[0028] The rollers 4 are all made of composite materials with good elasticity, such as thermoplastic elastomer, EPDM rubber or carbon fiber composite materials, which can easily disperse the impact force of the hull hitting the rollers 4, thereby improving the protection effect on the pier body 1.

[0029] The exteriors of the first bolts 5 and the second bolts 11 are coated with an anti-corrosion coating to prevent the first bolts 5 and the second bolts 11 from being corroded and rusted by water due to being immersed in water for a long time, making it convenient to replace the damaged rollers 4 and connecting rods 3 later.

[0030] In summary, when the composite bridge anti-collision device is used, it is installed by inserting the connecting rod 3 into the first mounting hole of the protective shell 2, and then inserting the other end of the connecting rod 3 into the second mounting hole 7 of the blocking cover 6, installing the protective shell 2, the connecting rod 3 and the blocking cover 6 together, screwing the first bolt 5 into the first threaded hole, fixing the blocking cover 6 on the protective shell 2, and then inserting the mutually cooperating protective shell 2 clamping plate 9 into the clamping groove 8 of the other protective shell 2, preliminarily clamping and fixing the mutually cooperating protective shells 2 on the pier body 1, and then screwing the second bolt 11 into the second threaded hole of the fixed block plate, so as to Several protective shells 2 are installed together. Then, when the hull hits the roller 4, the roller 4 rotates on the corresponding connecting rod 3 to change the direction of the hull. At the same time, the roller 4 drives the other rollers 4 in contact to rotate and transmits the impact force. The other rollers 4 disperse the impact force and transmit it to other rollers 4 in an array to disperse the impact force until all the impact force is completely dispersed. When a connecting rod 3 or roller 4 is damaged, just unscrew the second bolt 11 and the first bolt 5, remove the cover 6, and remove the damaged connecting pipe and roller 4 from the first mounting hole of the protective shell 2 for replacement.
