Description

Technical Field

[0001] This utility model relates to a bridge pier safety protection device, and more particularly to a device that can absorb the energy of a ship or obstacle impacting a bridge pier and protect the safety of the bridge pier and the ship, belonging to the field of bridge safety protection technology. Background Technology

[0002] Bridge piers are crucial structural components related to bridge safety, and the decks of various bridge types are supported by varying numbers of piers. Bridges built on navigable rivers and seas use anti-collision devices to protect piers from impacts by ships or water obstacles. Currently, the piers above the waterline are surrounded by a safety protection device consisting of multiple rubber balls connected by cables. These rubber balls, acting as elastic bodies, effectively absorb most of the impact energy through their elastic deformation upon impact, significantly reducing the impact energy on the pier and preventing damage, thus ensuring the safety of bridge traffic. However, the cables have a short lifespan and require frequent replacement. Once a cable breaks, the connection between the rubber balls immediately disintegrates, seriously affecting the safety of the pier. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2As shown, this embodiment includes an upper anti-collision unit 1 surrounding the bottom of the pier column 10 and a lower anti-collision unit 2 surrounding the pier abutment 20. The upper anti-collision unit 1 includes six upper rubber balls 30 and four sets of upper straight anchor chains 11. There are two upper rubber balls 30 on each of the longitudinal sides of the pier column 10 and one upper rubber ball 30 on each of the longitudinal ends. The diameter and length of the upper rubber balls 30 on the longitudinal ends of the pier column 10 are smaller than those on the longitudinal sides of the pier column 10. The six upper rubber balls 30 are connected in sequence by upper straight anchor chains 11 of unequal length to form a ring covering the bottom of the pier column 10, effectively protecting the pier column 10.

[0023] The lower anti-collision unit 2 includes six lower rubber abutments 40, two sets of T-shaped anchor chains 21, two sets of oblique T-shaped anchor chains 22, and two sets of V-shaped anchor chains 23. Two lower rubber abutments 40 are located on each of the two outer sides of the longitudinal direction of the pier cap 20, and one lower rubber abutment 40 is located at each of the two outer sides of the longitudinal direction of the pier cap 20. These two lower rubber abutments 40 are connected to both ends of the T-shaped anchor chains 21. The third end of each T-shaped anchor chain 21 is connected to a U-shaped hook 3 pre-embedded in the middle of the longitudinal direction of the pier cap 20. The diameter of the lower rubber abutment 40 on the right side of the pier cap 20 is smaller than that of the other lower rubber abutments 40, but its length is greater than that of the other lower rubber abutments 40. The two ends of the oblique T-shaped anchor chain group 22 are respectively connected to the adjacent ends of two lower rubber balls 40 located outside the left end of the pier foundation 20 and whose axes intersect at right angles.

The third end of the V-shaped anchor chain group 23 is respectively connected to the U-shaped hook ring 3 pre-embedded in the end corner of the right end of the pier foundation 20, thereby connecting the six lower rubber balls 40 in sequence to form a ring covering the pier foundation 20, effectively protecting the pier foundation 20.

[0024] Both the upper rubber ball 30 and the lower rubber ball 40 are cylindrical structures with rounded end faces. The outer diameter and length of the upper rubber ball 30 are smaller than those of the lower rubber ball 40, respectively.

[0026] like Figure 4 As shown, the T-shaped anchor chain assembly 21 includes a central ring 211, two sets of first anchor chain links 212, and one set of second anchor chain links 213. The second anchor chain link 213 has the same connection structure as the first anchor chain link 212, but its length is greater than that of the first anchor chain link 212. The first anchor chain link 212 includes sequentially connected end links 112, several ordinary links 111, and end links 112. The second anchor chain link 213 includes several ordinary anchor chain links 111 connected as a single unit and end links 112 at both ends. The chain diameter and length / width dimensions of the end links 112 are larger than those of the ordinary anchor chain links 111. The central ring 211 is connected to the end links 112 at one end of each of the two sets of first anchor chain links 212. The central ring 211 is also connected to the end links 112 at one end of the second anchor chain link 212 via shackles 113. The end link 112 of the other end of the first anchor chain link 212 is connected to the U-shaped ring base plate 302 of the corresponding rubber ball 40 end through shackles 113. The end link 112 of the other end of the third end of the positive T-shaped anchor chain group, namely the second anchor chain link 213, is connected to the outer end of the U-shaped hook 3 embedded in the middle of the longitudinal side of the pier abutment 20 through shackles 113.

[0027] like Figure 5 As shown, the oblique T-shaped anchor chain group 22 includes a central ring 211 and three sets of second anchor chain links 213. The end links 112 at one end of the two sets of second anchor chain links 213 are respectively connected to the central ring 211. The end links 112 at the other end of the two sets of second anchor chain links 213 are respectively connected to the U-shaped ring base plates 302 at the adjacent ends of the two lower rubber balls 40 on the left side of the pier foundation 20 and whose axes intersect at right angles through shackles 113. The end link 112 at one end of a second anchor chain link 213, which is the third end of the oblique T-shaped anchor chain group 22, is connected to the central ring 211 through shackles 113. The end link 112 at the other end of the second anchor chain link 213 is connected to the outer end of the U-shaped hook 3 pre-embedded in the left corner of the pier foundation 20 through shackles 113.

[0028] like Figure 6 As shown, the V-shaped anchor chain group 23 includes two sets of second anchor chain links 212. The end link 112 of one end of the second anchor chain link 212 is connected to the U-shaped ring base plate 302 of the adjacent ends of the two lower rubber balls 40 on the right side of the pier foundation 20 and whose axes intersect at right angles through shackles 113. The end link 112 of the other end of the second anchor chain link 212 is connected to the outer end of the U-shaped hook ring 3 embedded in the right corner of the pier foundation 20 through shackles 113.

[0029] like Figure 4 As shown, one end of the straight rod 31 on both sides of the U-shaped hook ring 3 is bent outward by 90° and then bent outward by 180° to form a hook-shaped end. The hook-shaped ends are respectively embedded in their corresponding positions in the pier foundation 20. This structure effectively improves the connection strength between the U-shaped hook ring 3 and the pier foundation 20, prevents the lower anti-collision unit 2 from detaching from the pier foundation 20, and improves the reliability of this utility model.

[0030] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
