Description

Technical Field

[0001] This utility model relates to the field of bridge protection technology, and in particular to a bridge railing with a quick positioning structure. Background Technology

[0002] Bridge railings with quick-positioning structures are railing systems designed for easy and rapid installation and dismantling. They typically include a quick-positioning device or structure that allows railing components to be quickly positioned and secured during bridge construction or maintenance. Existing bridge railings, with multiple anti-collision units, can effectively reduce the problem of vehicle rollover after a collision. However, during maintenance and protection, the railings cannot be precisely positioned, thus necessitating the use of bridge railings with quick-positioning structures.

[0003] An existing type of bridge railing with a quick-positioning structure adds anti-collision strips to the outside of the railing. When the railing is impacted, it will cause the vehicle to slide in a straight line and reduce the risk of rollover. However, subsequent railing maintenance cannot be done quickly by installing and positioning the railing. Therefore, when replacing the railing, there will be a situation where the bridge railing cannot be accurately positioned. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bridge railing with a quick positioning structure, which aims to improve the problem of bridge railings being unable to be accurately positioned.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge railing with a quick positioning structure, comprising a base, an outer shell fixedly connected to the outer wall of the base, a fixing plate fixedly connected to the outer wall of the outer shell, a first threaded rod threadedly connected to the inside of the fixing plate, a handle fixedly connected to one end of the first threaded rod, a slider rotatably connected to the other end of the first threaded rod, a lower surface of the slider slidably connected to the inner wall of the outer shell, a support block slidably connected to the upper surface of the slider, an outer wall of the support block slidably connected to the inside of the outer shell, a sliding hole provided inside the outer shell, a fixing shell attached to the upper surface of the outer shell, a first fixing block fixedly connected to the upper surface of the outer shell, a fixing post fixedly connected to the inside of the first fixing block, a first rotating block rotatably connected to the outer wall of the fixing post, and a spring-loaded component slidably connected to the upper surface of the first rotating block.

[0006] Preferably, the rebound assembly includes a sliding tube, the lower surface of which is slidably connected to the upper surface of the first rotating block, and a spring is slidably connected to the inner wall of the sliding tube. A limit hole is formed inside the first fixed block, and the outer wall of the spring is slidably connected to the inside of the limit hole.

[0026] Specifically, the first rotating block 11 supports the sliding tube 12, the sliding tube 12 slides upward to compress the spring 13, the limiting hole 14 inside the first fixing block 9 restricts the sliding tube 12 to prevent displacement, and the spring 13 slides inside the limiting hole 14.

[0027] Reference Figure 4 A second fixing block 16 is fixedly connected to the upper surface of the base 1. A first limiting post 17 is fixedly connected inside the second fixing block 16. A second rotating block 18 is rotatably connected to the outer wall of the first limiting post 17. The outer wall of the second rotating block 18 is rotatably connected to the inside of the second fixing block 16.

[0028] Specifically, the base 1 fixes the second fixing block 16, and the second rotating block 18 rotates inside the second fixing block 16 through the first limiting post 17, and the second fixing block 16 fixes the first limiting post 17.

[0029] Reference Figure 4 The second rotating block 18 is internally fixedly connected to a second threaded rod 19, and the outer wall of the second threaded rod 19 is threadedly connected to a nut 20;

[0030] Specifically, the second rotating block 18 fixes the second threaded rod 19, and the nut 20 rotates on the outer wall of the second threaded rod 19.

[0031] Reference Figure 4 The outer wall of the second threaded rod 19 is slidably connected to a limit strip 21, and the outer wall of the limit strip 21 is fixedly connected to a connecting plate 22;

[0032] Specifically, the second threaded rod 19 restricts the limiting strip 21, and the connecting plate 22 fixes the limiting strip 21.

[0033] Reference Figure 4 A connecting block 23 is fixedly connected to the outer wall of the connecting plate 22, and a second limiting post 24 is rotatably connected inside the connecting block 23. The outer wall of the second limiting post 24 is fixedly connected to the inside of the second fixing block 16.

[0034] Specifically, the connecting block 23 fixes the connecting plate 22, and the connecting block 23 rotates inside the second fixed block 16 via the second limiting post 24.

[0035] Reference Figure 1 A vertical rod 25 is fixedly connected to the upper surface of the base 1. The outer wall of the vertical rod 25 is slidably connected to the inside of the connecting plate 22. A horizontal brace 26 is fixedly connected to the outer wall of the vertical rod 25.

[0036] Specifically, the base 1 provides support for the vertical rod 25, the connecting plate 22 provides fixation for the vertical rod 25, and the vertical rod 25 provides fixation for the horizontal brace 26.

[0037] Reference Figure 2 A positioning block 27 is fixedly connected to the outer wall of the base 1, and a positioning hole 28 is opened inside the base 1. The outer wall of the positioning block 27 is slidably connected to the inside of the positioning hole 28.

[0038] Specifically, the base 1 plays a role in fixing the positioning block 27, and the outer wall of the positioning block 27 fits against the inside of the positioning hole 28 to prevent displacement.

[0039] Working principle: When this device is needed, first slide the positioning block 27 into the positioning hole 28 from top to bottom, with the base 1 having a fixed shell 15 on one side and an outer shell 2 on the other. At this time, the lower surface of the fixed shell 15 is in contact with the upper surface of the outer shell 2. Rotate the handle 5 of the first threaded rod 4 fixed on the fixed plate 3. The handle 5 drives the first threaded rod 4 to rotate, causing the slider 6 to push the support block 7 with its upper surface in contact with the sliding hole 8. The support block 7 pushes the first rotating block 11 fixed inside the first fixed block 9 upward inside the outer shell 2. The first rotating block 11 rotates around the fixed post 10. At the same time, the sliding tube 12 squeezes the spring 13 upward along the inside of the limiting hole 14, so that the first rotating block 11 is squeezed and fixed against the fixed shell 15, thereby achieving precise positioning of the guardrail, improving the accuracy and reliability of the operation, and ensuring the safety of the operation. After the base 1 is positioned, the vertical rod 25 is placed between the second fixing block 16 and the connecting plate 22. By allowing the limiting strip 21 to drive the connecting plate 22 fixed on the connecting block 23 to rotate around the second limiting post 24, the limiting strip 21 is made to fit against the outer wall of the second threaded rod 19. The second threaded rod 19 can rotate around the second rotating block 18 fixed by the first limiting post 17. The nut 20 is rotated to fix the limiting strip 21. After the vertical rod 25 is installed, the cross brace 26 is fixed in a suitable position, thereby achieving the goal of quick installation or disassembly of the guardrail, improving the efficiency of bridge maintenance or replacement. This device can not only achieve the effect of accurate positioning of the guardrail, improving the accuracy and reliability of the operation and ensuring the safety of the operation, but also allow the guardrail to be installed or disassembled quickly, improving the efficiency of bridge maintenance or replacement.
