Description

Technical Field

[0001] This utility model relates to the technical field of bridge protection devices, and in particular to a bridge pier protection device. Background Technology

[0002] Bridges, as vital links in road networks, especially those in mountainous areas, are frequently impacted by falling rocks and gravel, an impact that continues year after year and shows a trend of increasing severity. These rocks and gravel, with their powerful impact energy, often act on the bridge piers, causing vibrations that affect the bridge structure, thus impacting its lifespan and safety.

[0003] To address this issue, existing technologies typically involve installing a protective sleeve around the bridge pier (such as patent CN215329310U, which involves pouring a ring-shaped concrete layer around the bridge pier). While this can solve the collision problem, the impact direction of rolling stones on the bridge pier is relatively fixed, resulting in the protective sleeve always impacting in the same direction. Over time, this can cause the protective sleeve to fail in the impacted area, leading to a short service life. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bridge pier protection device. By setting a rotatable anti-collision protective sleeve, when the anti-collision protective sleeve fails due to long-term impact, it rotates so that the unimpacted part of the anti-collision protective sleeve faces the impact direction of the rolling stone, thus greatly improving the service life of the anti-collision protective sleeve.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A bridge pier protection device includes an anti-collision protective sleeve installed on the outside of the pier. The anti-collision protective sleeve is rotatably connected to the ground via a rotating component, which is used to drive the anti-collision protective sleeve to rotate circumferentially relative to the pier.

[0007] Furthermore, the rotating assembly includes an inner support ring plate, an outer support ring plate, and a rotating ring plate. The inner support ring plate is coaxially disposed outside the bridge pier and fixed to the ground. The outer support ring plate is coaxially disposed outside the inner support ring plate and fixed to the ground.

[0008] The rotating ring plate is coaxially arranged outside the pier, and the rotating ring plate is rotatably connected to the inner support ring plate and the outer support ring plate through a transmission component;

[0009] The anti-collision protective sleeve is located on the top surface of the rotating ring plate.

[0010] Furthermore, the transmission component includes a plurality of first rollers and a plurality of second rollers fixed to the rotating ring plate. The plurality of first rollers are evenly arranged along the inner support ring plate, and the plurality of second rollers are evenly arranged along the outer support ring plate.

[0011] Furthermore, the rotating ring plate includes multiple support frames and multiple support plates. The support frames are in the shape of an isosceles trapezoid, and the multiple support frames form a ring-shaped skeleton structure. The multiple support plates are isosceles trapezoidal plates adapted to the support frames, and the support plates are fixedly connected to the support frames.

[0012] Furthermore, the support plate is fixed to the support frame by bolts.

[0013] Furthermore, the support plate is welded and fixed to the support frame.

[0014] Furthermore, the outer support plate is also provided with two pin holes, and pins are provided in the pin holes. One of the second rollers is located between the two pins, and the two pins are used to restrict the circumferential movement of the second roller along the outer support ring plate.

[0015] Furthermore, the impact protection sleeve is made of concrete or rubber material.

[0016] The beneficial effects of this utility model are:

[0017] This invention features a rotatable anti-collision protective sleeve. When the sleeve fails due to prolonged impact, it rotates so that the unimpacted portion faces the direction of the downward impact of the rolling stone, thus significantly extending the lifespan of the protective sleeve.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-5 This utility model provides a technical solution:

[0026] Example:

[0027] like Figures 1-5 As shown, a bridge pier protection device includes a crash protection sleeve 2 made of concrete or rubber material installed on the outside of the pier 1. The crash protection sleeve 2 is rotatably connected to the ground through a rotating component 3, which is used to drive the crash protection sleeve 2 to rotate circumferentially relative to the pier 1.

[0028] The rotating assembly 3 includes an inner support ring plate 4, an outer support ring plate 5, and a rotating ring plate 6. The inner support ring plate 4 is coaxially arranged outside the pier 1 and fixed to the ground. The outer support ring plate 5 is coaxially arranged outside the inner support ring plate 4 and fixed to the ground.

[0029] The rotating ring plate 6 is coaxially arranged outside the pier 1, and the rotating ring plate 6 is rotatably connected to the inner support ring plate 4 and the outer support ring plate 5 through a transmission component;

[0030] The anti-collision protective sleeve 2 is located on the top surface of the rotating ring plate 6.

[0031] The transmission component includes a plurality of first rollers 7 and a plurality of second rollers 8 fixed to the rotating ring plate 6. The plurality of first rollers 7 (set on the inner ring of the rotating ring plate 6 and the second rollers 8 fixed on the outer ring of the rotating ring plate 6) are evenly arranged along the inner support ring plate 4, and the plurality of second rollers 8 are evenly arranged along the outer support ring plate 5.

[0032] The rotating ring plate 6 includes multiple support frames 9 and multiple support plates 10. The support frames 9 are in the shape of an isosceles trapezoid, and the multiple support frames 9 form a ring-shaped skeleton structure. The multiple support plates 10 are isosceles trapezoidal plates adapted to the support frames 9. The support plates 10 are fixedly connected to the support frames 9 by bolts or welding.

[0033] like Figure 5As shown, the outer support plate 10 is also provided with two pin holes 11, and pins 12 are provided in the pin holes 11. One of the second rollers 8 is located between the two pins 12. The two pins 12 are used to restrict the second roller 8 from moving circumferentially along the outer support ring plate 5.

[0034] When in use, the anti-collision protective sleeve 2 provides protection for the bridge pier 1. When rolling stones or gravel impact, the anti-collision protective sleeve 2 first buffers the impact. After buffering, the rolling stones fall to the side of the bridge pier 1, which plays a role in protecting the bridge pier 1 and preventing the rolling stones from directly impacting the bridge pier 1.

[0035] When using the anti-collision protective sleeve 2, periodically, or when maintenance personnel observe severe damage to the sleeve, remove the pin 12 to release the rotational limit of the rotating component 3. Then, manually push the anti-collision protective sleeve 2 until its unimpacted portion faces downwards in the impact direction of the rolling stone. Taking a 60-degree impact range of the rolling stone on the anti-collision protective sleeve 2 as an example, the anti-collision protective sleeve 2 of this invention can rotate 5 times and withstand 6 rolling stone impacts before failing, thus increasing its service life by 5 times.

[0036] After the anti-collision protective sleeve 2 is rotated into place, the pin 12 is reinserted (multiple sets of pins 12 can be set, such as four sets, distributed at 90-degree intervals on the outer support plate 10 to improve the limiting ability). The rotating component 3 cannot be rotated, thereby preventing the anti-collision protective sleeve 2 from rotating when it receives an impact.

[0037] This invention features a rotatable anti-collision protective sleeve. When the sleeve fails due to prolonged impact, it rotates so that the unimpacted portion faces the direction of the downward impact of the rolling stone, thus significantly extending the lifespan of the protective sleeve.

[0038] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
