Description
Technical Field
[0001] This utility model relates to the technical field of self-floating bridge pier anti-collision devices, and in particular to a combined assembled anti-collision device. Background Technology
[0002] Underwater piers are widely used in bridges and other water-based engineering projects, serving to support and stabilize them.
[0003] Patent CN113846606B discloses a prefabricated anti-collision facility for bridge piers in waterways. It includes multiple anti-collision pontoons arranged sequentially around the bridge pier. Each pontoon comprises a pontoon body and connecting parts. The pontoon body is a reinforced concrete structure. Two vertically distributed connecting parts are provided at both ends of the pontoon body. An internal energy-dissipating device is installed inside the pontoon to absorb and dissipate the impact energy when the pontoon body is impacted. The gaps inside the pontoon are filled with a polymer damping energy-dissipating material. When the pontoon body is damaged, the buoyancy of the polymer damping energy-dissipating material in the water is greater than the weight of the entire pontoon. The connecting parts are flexible rubber connections with built-in steel plates. A polymer collision steering device is also provided on the outer surface of the pontoon body away from the bridge pier, overcoming the deficiencies of existing anti-collision facilities and achieving comprehensive protection for both the bridge and the vessel.
[0004] In the above technical solution, multiple anti-collision pontoons are set up to facilitate the installation, transportation and maintenance of the anti-collision pontoons. However, some anti-collision pontoons are rectangular and some are semi-circular, which makes the processing of the anti-collision pontoons more inconvenient and is not conducive to improving the processing efficiency of the anti-collision pontoons. Utility Model Content
[0005] In view of this, this utility model proposes a combined assembly-type anti-collision device, which facilitates the transportation and maintenance of the floating frame, and also facilitates the processing of the floating frame, thereby improving the processing efficiency of the floating frame.
[0006] The technical solution of this utility model is implemented as follows: This utility model provides a combined assembled anti-collision device, including multiple floating frames, which are connected in sequence and form a ring; the multiple floating frames are located on the outside of the bridge pier, and two adjacent floating frames are detachably fixedly connected, and the multiple floating frames have the same shape and size;
[0007] The floating frame is provided with a buffer groove on the side near the pier, and when multiple floating frames are separated, a portion of one of the floating frames can be placed in the buffer groove on another floating frame.
[0008] Based on the above technical solutions, preferably, the floating frame includes an impact plate and a buffer plate. The impact plate has a buffer plate integrally formed at both ends along the circumference of the pier. The buffer plate is inclined to the impact plate, and the buffer plate and the impact plate enclose each other to form the buffer groove.
[0009] More preferably, the two buffer plates on the same floating frame are symmetrically arranged about the center line of the impact plate, and the distance between the two buffer plates on the same floating frame gradually increases along the direction from the impact plate to the pier.
[0010] More preferably, the floating frame further includes a connecting plate, with the connecting plate integrally formed at the end of each buffer plate away from the impact plate, and two adjacent connecting plates are connected by bolts.
[0011] More preferably, the connecting plate on the same floating frame is parallel to the impact plate.
[0012] More preferably, the system also includes multiple rubber pads, which are fixedly installed on the side of the floating frame near the pier, and each rubber pad corresponds to one of the floating frames.
[0013] More preferably, when the two connecting plates are parallel, the rubber pad is fixedly disposed between the two connecting plates;
[0014] When the two connecting plates are perpendicular to each other, the rubber pad is fixedly installed on one of the connecting plates.
[0015] Based on the above technical solutions, preferably, it also includes a cushioning material, wherein the float has a hollow structure and the cushioning material is filled and disposed inside the float.

[0019] (2) By setting the floating frame to include a collision plate and two buffer plates that are symmetrical about the center line of the collision plate and inclined to the collision plate, adjacent floating frames can be spaced apart to reduce the damage to the anti-collision device caused by ship collisions, thereby reducing the maintenance cost of the anti-collision device.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] like Figure 1-4 As shown, this utility model provides a combined assembled anti-collision device, which includes multiple floating frames 1, multiple rubber pads 2, and buffer material 3. It floats on the water surface and wraps around the pier 4 in the water to prevent the ship from directly hitting the pier 4.
[0028] The floating frame 1 is the main structure of this anti-collision device, used to buffer the impact of ships. It floats on the water surface. Multiple floating frames 1 are connected in sequence along a circular path (which can be a circular ring or a rectangular ring, etc., depending on the specifications of the pier 4) to form a ring structure. Multiple floating frames 1 are located on the outside of the pier 4. Adjacent floating frames 1 are detachably fixedly connected, and multiple floating frames 1 are the same in shape and size. The anti-collision device is composed of multiple floating frames 1, which modularizes an integral structure and decomposes it into multiple small components. This facilitates the transportation and maintenance of this anti-collision device. Since multiple floating frames 1 are the same in shape and size, they can be mass-produced, which helps to improve the processing efficiency of floating frames 1.
[0029] A buffer trough 101 is provided on the side of the floating frame 1 closest to the pier 4, and when multiple floating frames 1 are separated, a portion of one floating frame 1 can be placed within the buffer trough 101 on another floating frame 1, such as... Figure 3 As shown, when transporting multiple floating frames 1, the space occupied by multiple floating frames 1 can be reduced by utilizing the space coordination of the buffer trough 101. At the same time, the setting of the buffer trough 101 can also allow the local part of the floating frame 1 to be spaced apart from the bridge pier 4, thereby playing a certain buffering effect and preventing the impact force from being directly transmitted to the bridge pier 4 after the ship hits the floating frame 1.
[0030] like Figure 2 As shown, the floating frame 1 includes a collision plate 11, a buffer plate 12, and a connecting plate 13. A buffer plate 12 is integrally formed at each end of the collision plate 11 along the circumference of the pier 4. The buffer plate 12 is inclined to the collision plate 11, and the buffer plate 12 and the collision plate 11 enclose each other to form a buffer groove 101. The buffer groove 101 is formed by the direct enclosed connection of the buffer plate 12 and the collision plate 11. Figure 3 As shown, the inclination of the inner wall of the buffer groove 101 is consistent with the inclination of the outer side of the float 1, so that when multiple floats 1 are stacked, the two adjacent floats 1 can fit together more closely, so as to ensure the stacking stability of multiple floats 1 during transportation.
[0031] like Figure 2 As shown, the two buffer plates 12 on the same floating frame 1 are symmetrically arranged about the center line of the impact plate 11, which can improve the uniformity of force distribution at both ends of the floating frame 1; the distance between the two buffer plates 12 on the same floating frame 1 gradually increases along the direction from the impact plate 11 connected to them to the pier 4, as shown. Figure 1 As shown, by utilizing the symmetrical arrangement of the buffer plate 12 and its inclined arrangement with the collision plate 11, the floating frame 1 can maintain a certain degree of independence. When a ship hits a collision plate 11 and the impact force is small, the floating frame 1 can be prevented from deforming and damaging the adjacent floating frame 1, thereby reducing the maintenance cost of this anti-collision device.
[0032] Because the buffer plate 12 and the impact plate 11 are inclined, a certain gap will appear between two adjacent floating frames 1. When setting up the floating frames 1, the included angle between the buffer plate 12 and the impact plate 11 needs to be adjusted according to the actual situation. Figure 1 As shown, the gaps on the top and bottom sides of pier 4 should not be greater than the front width of a typical ship hull. Since the upper left, lower left, upper right, and lower right sides of pier 4 are not easily hit by ships, these gaps do not need to be designed to avoid collisions.
[0033] The connecting plate 13 is the connecting structure of the float 1. Each buffer plate 12 has a connecting plate 13 integrally formed at the end away from the impact plate 11. The two adjacent connecting plates 13 on the two adjacent floats 1 are connected by bolts, thereby realizing the detachable fixed connection of the two adjacent floats 1.
[0034] Of course, to improve the connection strength of the connecting plate 13, the number of bolts used can be increased or bolts with higher structural strength can be used.
[0035] like Figure 1 As shown, a tension bolt, i.e., a bolt consisting of a screw and two nuts, can be used. The connecting plate 13 has one or more through holes. When the screw is inserted into the through holes of two adjacent connecting plates 13, the two nuts are screwed onto the two ends of the screw respectively, and the two nuts abut against the two connecting plates 13, so that the two connecting plates 13 can be detachably fixedly connected.
[0036] To improve the balance and symmetry of the float 1, the connecting plate 13 on the same float 1 is preferably parallel to the impact plate 11.
[0037] When multiple floating frames 1 are arranged in a ring, in order to make the connection between two adjacent floating frames 1 more compact and stable, such as Figure 1 As shown, the two connecting plates 13 are either set parallel to each other or perpendicular to each other.
[0038] The surface of the connecting plate 13 that connects with the nut has two types: a flat surface and an inclined surface. The flat surface is perpendicular to the screw, and the inclined surface is inclined to the screw. When the nut abuts against the flat surface of the connecting plate 13, the nut can directly abut against the flat surface of the connecting plate 13. When the nut abuts against the inclined surface of the connecting plate 13, a wedge-shaped pad can be placed between the nut and the connecting plate 13 to improve the firmness of the bolt connection to the connecting plate 13.
[0039] The rubber pad 2 is used to buffer the floating frame 1 and the pier 4. The rubber pad 2 is fixedly installed on the side of the floating frame 1 close to the pier 4, and the rubber pad 2 corresponds to the floating frame 1 one by one. When the floating frame 1 is hit by a ship, the rubber pad 2 can absorb and buffer the impact force, thus protecting the pier 4.
[0040] like Figure 1 As shown, when the two connecting plates 13 are parallel, the rubber pad 2 is fixedly installed between the two connecting plates 13; when the two connecting plates 13 are perpendicular, the rubber pad 2 is fixedly installed on one of the connecting plates 13, so that the rubber pad 2 can play a more balanced and stable protective role.
[0041] The buffer material 3 is used to improve the anti-collision performance of the float 1. The float 1 has a hollow structure, and the buffer material 3 is filled and placed inside the float 1. The float 1 can be designed with a steel structure, while the buffer material 3 can be made of materials with buffering effect such as rubber, so that when the float 1 is hit, part of the impact force is absorbed and transformed.
[0042] like Figure 1 As shown, in order to improve the buffering effect of this anti-collision device, the floating frame 1 and the pier 4 can be set at intervals. When this anti-collision device is hit by a ship, it can be moved laterally for a certain distance to avoid the impact force being directly transmitted to the pier 4.
[0043] The method of using the combined assembled anti-collision device of this utility model is as follows:
[0044] First, the dimensions and quantity of the floating frame 1 are designed according to the shape of the bridge pier 4, and batch processing is carried out. Then, according to... Figure 3 Multiple floating frames 1 are stacked as shown and transported to the construction site of bridge pier 4. Finally, the multiple floating frames 1 are arranged as follows: Figure 1 The bridge is assembled as shown so that it floats on the water to protect pier 4.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
