Description

Technical Field

[0001] This utility model relates to the field of bridge railing support, and in particular to a bridge railing support device that is easy to assemble and disassemble. Background Technology

[0002] Bridge railings are guardrails installed on bridges, fixed to the edges of the bridge by bolts, pouring concrete, or other methods. They prevent out-of-control vehicles from going off the bridge and also beautify the bridge. During installation, bridge railings need to be erected and positioned first, so that they can be fixed through various subsequent processes. Using bridge railing support devices can improve the stability and accuracy of positioning, thereby improving the installation effect.

[0003] Most existing bridge railing support devices have fixed support structures. After the support structure is installed, the vertical and horizontal pipes of the bridge railing are placed on the support structure. During use, the support structure is gradually removed from the bridge structure. At the same time, the workload of bridge railings is large, which makes the loading and unloading time long, resulting in a decrease in the efficiency of the bridge railing support device.

[0004] Therefore, in view of the problem that the existing bridge railing support devices require the support structure to be gradually removed from the bridge structure during use, and that the large workload of bridge railings results in a long loading and unloading time, leading to a decrease in the efficiency of the bridge railing support devices, a bridge railing support device that is easy to disassemble and assemble can be designed.

A gripper body 26 for restraining the railing horizontal tube is rotatably connected to the upper end of the extension rod 25 via a rotating shaft. The rotating platform 18 is moved by the frame body 1 and the moving platform 13, and the rotating platform 18 is used for installation and relocation. The movable lifting platform 21 uses the guardrail tube bracket 22 and the limiting plate 23 to fix the vertical installation tube of the bridge guardrail. The extension rod 25 and the rotating rod 24 are used to move the gripper body 26 and clamp and fix the horizontal installation tube of the bridge guardrail, and drive the bridge guardrail to rise and fall, which facilitates subsequent installation and fixing. The two ends of the frame body 1 are rotatably connected to the support roller 2 through the rotating shaft. The front end of the frame body 1 is slidably connected to the extension plate 3. The rotating platform 18 is moved by the frame body 1 and the support roller 2 to move the bridge guardrail. The front end of the extension plate 3 is rotatably connected to the support block 4 through the rotating shaft. The inner side of the extension plate 3 is installed with the support plate 5. The upper end of the frame body 1 is fixedly connected to the fixing block 6. The outer side of the fixing block 6 is rotatably connected to the positioning platform 7. The support block 4 supports the extension plate 3 and the frame body 1, and the support plate 5 is used to prevent the counterweight from balancing.

[0024] Please see Figures 3-5In this embodiment, a gear frame 8 is installed at the front end of the positioning platform 7. A first gear 9 is rotatably connected to the inner side of the gear frame 8 via a rotating shaft. Second gears 10 are meshed on both sides of the first gear 9. Third gears 11 are meshed on the outer sides of both second gears 10. A first threaded rod 12 is fixedly connected to the rear end of the third gear 11. The first gear 9 and second gears 10 drive the third gear 11 to rotate, thereby driving the two first threaded rods 12 to rotate. A support rod 14 is threadedly connected to the outer side of the first threaded rod 12. The support rod 14 is fixedly connected to the moving platform 13 and slidably connected to the positioning platform 7. First rotating seats 15 are fixedly connected to both sides of the moving platform 13. 12, together with the positioning platform 7 and gear frame 8, drives the support rod 14 and the moving platform 13 to move.

The inner side of the second rotating seat 16 is rotatably connected to the rotating platform 18 through a rotating shaft. The rear end of the rotating platform 18 is provided with a sliding groove 19. The two ends of the rotating platform 18 are rotatably connected to the second threaded rod 20 through a rotating joint. The second threaded rod 20 is threadedly connected to the lifting platform 21. The second threaded rod 20 and the rotating platform 18 drive the lifting platform 21 to rise and fall, connecting the bridge railing to the bridge and fixing it.

[0025] In use, firstly, the vertical installation tube of the bridge railing is fixed by the railing tube bracket 22 in conjunction with the limiting plate 23. Then, the extension rod 25 is used in conjunction with the rotating rod 24 to move the gripper body 26 and clamp and fix the horizontal installation tube of the bridge railing. Then, the rotating platform 18 is moved by the frame body 1 and the moving platform 13, and the lifting platform 21 is installed and moved by the rotating platform 18, which drives the bridge railing to rise and fall, which facilitates subsequent installation and fixing. Finally, the rotating platform 18 is moved by the frame body 1 and the supporting rotating roller 2 to move the bridge railing.

[0026] During the installation of the guardrail, firstly, the extension plate 3 and the main body of the frame 1 are supported by the support block 4, and the counterweight is used to prevent imbalance by the support plate 5. The docking position of the guardrail is adjusted by the positioning platform 7. Next, the first gear 9 and the second gear 10 drive the third gear 11 to rotate, thereby driving the two first threaded rods 12 to rotate, which in turn drives the support rod 14 and the moving platform 13 to move. Then, the bridge guardrail and the rotating platform 18 are rotated, and the rotating platform 18 is constrained by the rotating limit frame 17 to fix the bridge guardrail. Finally, the second threaded rod 20 and the rotating platform 18 drive the lifting platform 21 to rise and fall, so as to connect the bridge guardrail to the bridge and fix it.

[0027] Through the above steps, the rotating platform 18 is moved by the frame body 1 and the moving platform 13, and the lifting platform 21 is installed and moved by the rotating platform 18. The vertical installation pipe of the bridge railing is fixed by the guardrail tube bracket 22 in conjunction with the limiting plate 23. The extension rod 25 is used in conjunction with the rotating rod 24 to move the gripper body 26 and clamp and fix the horizontal installation pipe of the bridge railing, and drive the bridge railing to rise and fall, which facilitates subsequent installation and fixing. This solves the problem that when using existing bridge railing support devices, the support structure needs to be gradually removed from the bridge structure. At the same time, the workload of bridge railings is large, which makes the loading and unloading time long, resulting in a decrease in the efficiency of the bridge railing support device.
