Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction protection, in particular to a bridge construction protection fence. Background Art

[0002] As we all know, bridges generally refer to structures built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other traffic needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. During bridge construction, protective warning fences are required to prevent outsiders from breaking in and warn construction workers of the location of the safe area;

[0003] The existing bridge construction guardrails are bulky to install, time-consuming and labor-intensive to move, and extremely inconvenient. As the construction progresses, the guardrails need to be moved forward along with the construction, which consumes a lot of manpower and increases costs. In addition, during bridge construction, it is inevitable that debris and rocks will fall under the bridge, which may injure pedestrians under the bridge. In view of the above problems, the present application designs a bridge construction guardrail. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a bridge construction guardrail, which has the following beneficial effects:

[0015] The bridge construction guardrail uses the telescopic mechanism and the universal wheel to achieve convenient transportation and movement of the guardrail without reducing the protection length.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A bridge construction guardrail comprises a main panel 1, a telescopic mechanism for telescopic guardrail is arranged on the main panel 1, the telescopic mechanism comprises a first motor 2, first slide grooves 3 are arranged on both sides of the main panel 1, the first motor 2 is installed in the first slide grooves 3, a bidirectional threaded rod 4 is fixed to the output end of the first motor 2, two first sliders 5 are threadedly connected to the bidirectional threaded rod 4, a telescopic frame 6 is rotatably connected to the two first sliders 5, and two second sliders 7 are rotatably connected to the other end of the telescopic frame 6, support columns 8 are arranged on both sides of the main panel 1, and a second The second slider 7 is slidably connected to the second slider 9, and storage bins 10 are arranged on both sides of the rear end of the main panel 1. A rotating shaft 11 is rotatably connected in the storage bin 10. A second motor 12 is installed on the upper end of the storage bin 10. The output end of the second motor 12 passes through the storage bin 10 and is fixedly connected to the rotating shaft 11. A protective net 13 is arranged on the rotating shaft 11. One end of the protective net 13 is fixed to the support column 8 on the same side of the storage bin 10. Two universal wheels 14 are installed at the bottom end of the support column 8. A support leg 15 is fixed to the lower end of the main panel 1, and two universal wheels 14 are installed at the lower end of the support leg 15.

[0023] When the device is in use, the guardrail is moved to a designated position, the first motor 2 is started to drive the bidirectional threaded rod 4 to rotate, the first slider 5 threadedly connected to the bidirectional threaded rod 4 moves toward the middle along the first slide groove 3, so that the telescopic frame 6 is extended, and the second slider 7 moves toward the middle along the second slide groove 9 at the same time. Through the action of force, the support columns 8 on both sides move toward both sides by the universal wheels 14 to achieve the extension of the guard frame. While the guard frame is extended, the second motor 12 is started to drive the rotating shaft 11 to rotate, and the rotating shaft 11 rotates outward to loosen the guard net 13. The other end of the guard net 13 is fixed on the support column 8. As the support column 8 moves to both sides, the guard net 13 is extended.

[0024] It is found in actual use that some people are unaware of the protection provided by the guardrail alone. In order to warn others more intuitively and clearly, in this embodiment, an LED warning panel 16 is installed at the front end of the main panel 1.

[0025] It was found in actual use that due to the installation of the universal wheel 14, the guardrail would slide, resulting in a change in the protection area. In order to solve the above problem, in this embodiment, a cylinder 17 is installed in the support column 8, and the output end of the cylinder 17 passes through the support column 8 and is fixed downwardly with a support block 18, and the support block 18 is provided with anti-slip grooves.

[0026] It is found in actual use that the guardrail is not easily discovered in a dimly lit environment. In order to avoid the problem, in this embodiment, a warning light 19 is installed at the upper end of the support column 8.

[0027] It was found during implementation that the protection length was relatively long during actual protection. In order to achieve long-distance continuous protection, in this embodiment, a first connecting block 20 is fixed to the right side of the right support column 8, and a second connecting block 21 is fixed to the left side of the left support column 8. Threaded holes are provided on the first connecting block 20 and the second connecting block 21.

[0028] It was found during implementation that when arranging guardrails, it is often necessary to bundle reflective warning tapes. When bundling on traditional guardrails, it is rather messy and inconvenient. In order to solve the above problem, in this embodiment, a bundling column 22 is fixed to the front end of the support column 8.
