Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
As shown in fig. 1 and 2, a box culvert pier stud anti-collision structure comprises pier studs 110 arranged on a river bank, wherein a fender 500 is arranged on one side of each pier stud 110 facing the river surface, a circumferential pressure relief assembly 600 is further arranged outside the fender 500, the circumferential pressure relief assembly 600 is arranged around the pier studs 110, and the circumferential pressure relief assembly 600 comprises an anti-impact plate 610 and a compression-resistant buffer 630. The pier stud 110 outer wall area with the fender 500 equal in height is a buffer area, and the compression-resistant buffer 630 is arranged in the buffer area. The fender 500 is covered with an arc-shaped impact-resistant plate 610, the concave surface of the impact-resistant plate 610 faces the fender 500, the impact-resistant plate 610 is connected with a flexible tension band 620, the tension band 620 surrounds the buffer area, two ends of the tension band 620 are freely crossed and then respectively connected with two ends of the impact-resistant plate 610, and when the convex surface of the impact-resistant plate 610 is pressed, the impact-resistant plate 610 drives two ends of the tension band 620 to be away from each other and enables the tension band 620 to inwards extrude the compression-resistant buffer 630.
The impact resistant plate 610 is a plate having a high rigidity and is capable of deforming to some extent even when a large impact force is applied thereto, and may be a steel plate, for example. The tension band 620 is made of a material having a high tensile strength, and preferably has a smooth surface, and may be made of, for example, a fiber composite material, or a steel wire woven material, and the outer surface of the tension band is covered with a polymer material. The tension band 620 has opposite ends respectively abutting against corresponding ends of the anti-impact plate 610, and is clamped by the steel plate and connected thereto by bolts. When a ship collides with the anti-impact plate 610, impact force is transmitted from the anti-impact plate 610 to the tension band 620 to be tensioned, and the tensioned tension band 620 acts on the compression-resistant buffer 630, so that the impact force is dispersed to the compression-resistant buffer 630 to perform a buffering function. At the same time, the impact resistant plate 610 that is impacted is also pressed against the fender 500 located inside thereof, and the deformation of the fender 500 will further dissipate the impact force. The transmission of force between the impact plate 610 and the tension band 620 is similar to the transmission of force between a bow and a string, so that the tension band 620 should not be in a relaxed state but should be slightly tensioned when no external force is applied.
As shown in fig. 3, a through hole 621 is formed on the tension belt 620 near one end thereof, a partial width of the tension belt 620 near the other end thereof is narrowed to form a slip segment 622, and the slip segment 622 is movably inserted into the through hole 621. Thus, when the impact-resistant plate 610 is deformed, the slip segment 622 easily slides in the via hole 621.
The compression-resistant damper 630 is made of an elastic material, and the compression-resistant damper 630 has an inner cavity filled with a fluid. Thus, the compression buffers 630 are deformed and provide a certain reverse resistance when they are subjected to the compression force of the tension band 620, thereby consuming energy.
In a preferred embodiment, the inner cavity of the compression resistant bumper 630 is filled with a non-Newtonian fluid. The non-newtonian fluid is characterized by easy flow deformation when slowly pressurized thereto and exhibits rigidity when rapidly pressurized, so that when the impact-resistant plate 610 is rapidly deformed by a large impact force, the tension band 620 is rapidly pressurized against the compression bumper 630, and the compression bumper 630 can stably disperse tension on the tension band 620 to the pier stud 110.
In this embodiment, at least two of the pressure-resistant buffers 630 are disposed in the buffer region, the pressure-resistant buffers 630 are cylindrical, the pressure-resistant buffers 630 are vertically disposed, and all of the pressure-resistant buffers 630 wind the pillars 110 in the buffer region. The tension on the tension band 620 is dispersed to the pier stud 110 by the plurality of compression buffers 630.
The compression bumper 630 may be installed as follows: as shown in fig. 2 and 4 to 6, a buffer mounting base 640 is fixedly disposed on the buffer area, and the buffer mounting base 640 includes a rectangular bendable bottom plate 641, and the bottom plate 641 extends in the horizontal direction and is fixedly attached to the buffer area. Specifically, two long edges of the bottom plate 641 are respectively connected with a fixing lug 646, and a bolt is inserted into the fixing lug 646 to fix the bumper mounting base 640 on the pier stud 110.
The outer walls of the two ends of the pressure-resistant buffer member 630 are respectively and fixedly connected with clamping columns 631, the free ends of the two clamping columns 631 respectively extend into the corresponding strip holes 643, and the two clamping columns 631 respectively fall on the pair of positioning notches 644 which are opposite to each other from top to bottom. The free end of the locking post 631 is connected with an anti-drop head to prevent the locking post 631 from dropping out of the elongated hole 643 and the positioning notch 644.
In this manner, a flexible arrangement of a number and diameter of the pressure-resistant bumpers 630 is facilitated. Moreover, the pressure-resistant buffer 630 can be lifted upwards as required, so that the clamping post 631 can slide in the elongated hole 643, the position of the pressure-resistant buffer 630 can be moved along the elongated hole conveniently, after the position is moved in place, the external force is removed, and the clamping post 631 on the pressure-resistant buffer 630 automatically falls into the corresponding positioning notch 644, so as to be positioned.
In order to facilitate the installation of the compression-resistant buffer 630, as shown in fig. 4, mounting holes 645 are respectively formed on the groove bottom of the support locking groove 642 corresponding to two ends of the elongated hole 643, the mounting holes 645 are communicated with the elongated hole 643, and the diameter of the mounting holes 645 is larger than the outer diameter of the drop-proof head, so as to allow the snap-in columns 631 to be placed in or taken out of the mounting holes 645.
The buffer mounting seat 640 may be made of a material having both rigidity and flexibility, such as rubber, and may be reinforced by a built-in steel wire mesh in order to further improve the toughness and increase the rigidity properly.
Because the supporting fastening groove 642 protrudes out of the bottom plate 641, the radial sizes of the two ends of the compression-resistant buffer 630 are reduced, the fastening post 631 is radially connected to the small diameter portion of the compression-resistant buffer 630, and the middle body of the compression-resistant buffer 630 is attached to the bottom plate 641. The pressure-resistant buffer 630 may be made of rubber material, and the catching posts 631 are integrally formed at the ends thereof.
In this embodiment, a row of fenders 500 is distributed along the circumferential direction of the pier 110 on the side wall thereof facing the river surface at the same height of the pier 110. The fender 500 may be a mature rubber fender. On each pier stud 110, one or more rows of fenders 500 are provided as required. A respective set of circumferential pressure relief assemblies 600 are provided outside each row of fenders 500 to help distribute the impact forces as the impact resistant panel 610 is impacted and the displacement of the impact resistant panel 610 is applied to the entire row of fenders 500.
Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and that those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
