Description

Technical Field

[0001] This utility model relates to the field of crash barrier technology, and in particular to a prefabricated crash barrier for municipal engineering. Background Technology

[0002] In municipal engineering projects, protective railings are often installed outside the construction site to protect construction workers. Chinese utility model patent, authorized publication number "CN216515321U", discloses a prefabricated crash barrier for municipal engineering, comprising a single panel. A support plate is fixed to the bottom outer wall of the single panel, and a short shaft is fixed to the bottom of the support plate. A sliding mechanism is provided at the bottom of the base plate. A sliding groove is formed on one side outer wall of the single panel, and a connecting component is inserted into the inner wall of the sliding groove. Two single panels are connected through the sliding groove and the connecting component. A control mechanism is provided on the inner wall of the single panel.

[0003] The above technical solution selects a specific number of single panels according to the site conditions. Two single panels are connected by inserting sliders into the inner wall of the slot. The fence device composed of multiple single panels can be bent according to the shape of the fence location required on site. The connecting plate one and connecting plate two facilitate bending. At this time, the area that needs protection can be reliably fenced off. It is highly practical and has a wide range of applications due to its modular assembly. Its bottom is fixed to the ground by roller locking. However, the anti-collision function involved in this technical solution is poor. Therefore, there is an urgent need for a prefabricated anti-collision guardrail for municipal engineering that can solve the above problems based on the existence of rollers. Utility Model Content

[0023] Please see Figure 1-3 This utility model provides a technical solution: a prefabricated anti-collision guardrail for municipal engineering, including guardrail 5;

[0024] The lower end of the guardrail 5 is provided with a support assembly, which includes two rollers 12, a base plate 13, an annular part 14, a threaded post 15, and a knob 16. The base plate 13 is rotatably connected to the lower end of the guardrail 5. Two rollers 12 are rotatably connected to the surface of the base plate 13. The annular part 14 is slidably connected to the surface of the base plate 13. The height of the annular part 14 is greater than the height of the base plate 13. The lower end of the base plate 13 is flush with the lower end of the annular part 14. The annular part 14 is threadedly connected to the surface of the annular part 14. The knob 16 is welded to the surface of the threaded post 15. The surface of the threaded post 15 is in contact with the surface of the base plate 13.

[0025] A sleeve 7 is welded to the right side of guardrail 5, and a limit post 10 slides inside sleeve 7.

[0026] A magnet 11 is fixedly connected to the upper end of the limiting post 10, and a sleeve 4 is welded to the left side of the guardrail 5.

[0027] The sleeve 4 has a sliding connection to a connecting post 2, and a magnet 8 is fixedly connected to the lower end of the connecting post 2. The magnet 11 and the magnet 8 attract each other.

[0028] A circular piece 1 is welded to the upper end of the connecting column 2, and a spring 3 is welded to the lower end of the circular piece 1. The lower end of the spring 3 is fixedly connected to the upper end of the sleeve 4.

[0029] A column 6 is welded to the left side of the guardrail 5, and a slot 9 is provided on the surface of the column 6.

[0030] It should be noted that spring 3 is in a stretched state in the initial state.

[0031] When it is necessary to assemble the guardrail;

[0032] First, an external force drives the guardrail 5 to move. The movement of the guardrail 5 drives the sleeve 7 to move. The movement of the sleeve 7 drives the limiting post 10 to move. The movement of the limiting post 10 drives the magnet 11 to move to the lower end of the corresponding magnet 8 of the other guardrail 5. The magnet 8 and the magnet 11 attract each other. Then, the disc 1 is released, the spring 3 resets and drives the disc 1 to move downward. The downward movement of the disc 1 drives the connecting post 2 to move downward. The downward movement of the connecting post 2 drives the magnet 8 to move downward. The downward movement of the magnet 8 drives the magnet 11 to move downward. The downward movement of the magnet 11 drives the limiting post 10 to move downward into the slot 9.

[0033] Secondly, the knob 16 is moved by an external force, and the movement of the knob 16 causes the threaded column 15 to move, loosening the positional relationship between the annular part 14 and the base plate 13. Then, the annular part 14 is moved downward by an external force until it contacts the ground. Then, the knob 16 is moved by an external force, and the movement of the knob 16 tightens the positional relationship between the annular part 14 and the base plate 13.

[0034] By incorporating a ring-shaped component 14 in the support assembly, the ring-shaped component 14 can replace the two rollers 12 to support the guardrail, thereby increasing the contact area between the guardrail and the ground and improving the guardrail's stability against impact.

[0035] By setting the limiting post 10, it can be locked inside the slot 9 to achieve the assembly effect, so that the appropriate number of guardrails can be selected according to the protection area and assembled, thereby expanding the practicality of the guardrail.

[0036] Working principle:

[0037] When it is necessary to assemble the guardrail;

[0038] First, an external force drives the guardrail 5 to move. The movement of the guardrail 5 drives the sleeve 7 to move. The movement of the sleeve 7 drives the limiting post 10 to move. The movement of the limiting post 10 drives the magnet 11 to move to the lower end of the corresponding magnet 8 of the other guardrail 5. The magnet 8 and the magnet 11 attract each other. Then, the disc 1 is released, the spring 3 resets and drives the disc 1 to move downward. The downward movement of the disc 1 drives the connecting post 2 to move downward. The downward movement of the connecting post 2 drives the magnet 8 to move downward. The downward movement of the magnet 8 drives the magnet 11 to move downward. The downward movement of the magnet 11 drives the limiting post 10 to move downward into the slot 9.

[0039] Secondly, the knob 16 is moved by an external force, and the movement of the knob 16 causes the threaded column 15 to move, loosening the positional relationship between the annular part 14 and the base plate 13. Then, the annular part 14 is moved downward by an external force until it contacts the ground. Then, the knob 16 is moved by an external force, and the movement of the knob 16 tightens the positional relationship between the annular part 14 and the base plate 13.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
