Description

Technical Field

[0001] The utility model relates to the field of warning guardrails, in particular to a warning guardrail for water conservancy and hydropower construction. Background Art

[0002] As an important safety facility, the background of warning guardrails is closely related to people's needs for safety and protection. With the continuous development of society, people's attention to the safety of life and property is also increasing. Therefore, various safety protection measures have emerged. The main function of the warning guardrails for water conservancy and hydropower construction is to remind and guide personnel and vehicles on the construction site to pay attention to the dangers in the construction area to avoid safety accidents. Its design fully considers the complexity and variability of the construction environment. It is made of sturdy and durable materials that can withstand certain impacts and extrusions. At the same time, the color and logo of the warning guardrails are also carefully selected to improve its visibility and warning effect. The warning guardrails have a wide range of applications, including the boundaries of the construction area, temporary roads, dangerous areas, etc. They can effectively isolate and block dangerous areas, prevent non-construction personnel from entering by mistake, and reduce safety risks. At the same time, the warning guardrails can also play a role in guiding construction vehicles and personnel to ensure the order of the construction site.

[0003] However, the existing warning guardrails are generally fixed guardrails, so that the height of the guardrail cannot be adjusted according to the height of the warning terrain during use, so that people cannot see the warning guardrails in areas with low terrain, and when storing the guardrails, they are large in size, making storage more troublesome. For this reason, we propose a water conservancy and hydropower construction warning guardrail. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a water conservancy and hydropower construction warning guardrail, which has the following beneficial effects:

[0018] 1. The water conservancy and hydropower construction warning guardrail moves the vertical end of the handle upward inside the sleeve through the folding handle transverse end, so that the top of the folding handle squeezes the spring while the bottom of the folding handle drives the fixing rod to leave the circular groove of the fixing plate, and then pulls the guardrail top plate backward, so that the guardrail top plate drives the second guardrail support rod to rotate around the movable plate, so that the second guardrail support rod drives the first guardrail support rod to fold on the guardrail bottom plate, thereby reducing the space occupied by the guardrail and making it easy to store the guardrail in a narrow place.

[0027] A control device for quickly folding the guardrail is provided at the bottom of the guardrail top plate 3;

[0028] A telescopic device for adjusting the height of the first guardrail support rod 5 is disposed inside each of the four second guardrail support rods 6 .

[0029] Furthermore, the four first guardrail support rods 5 and the second guardrail support rods 6 are both hollow, and limiting holes 10 are provided on the inner walls on both sides of the four first guardrail support rods 5, and the tops of the four second guardrail support rods 6 are movably connected to the inside of the four first guardrail support rods 5.

[0030] Furthermore, the control device includes a folding handle 11, a fixed rod 12, a fixed plate 14, a fixed block 15, a sleeve 16 and a connecting plate 17. The top of the guardrail top plate 3 is fixedly connected to two connecting plates 17, the bottom of the two connecting plates 17 is fixedly connected to the sleeve 16, the inside of the sleeve 16 is movably connected to the folding handle 11, the bottom end of the folding handle 11 is fixedly connected to the fixed rod 12, the bottom end of the fixed rod 12 is movably connected to the fixed plate 14, and one end of the fixed plate 14 is fixedly connected to the fixed block 15.

[0031] Furthermore, the folding handle 11 is L-shaped, and a spring 13 is fixedly connected between the vertical end of the folding handle 11 and the guardrail top plate 3 corresponding to the middle of the two connecting plates 17, and the lateral end of the folding handle 11 is movably connected to the inside of the sleeve 16.

[0032] Furthermore, one end of the fixing plate 14 is in an inclined shape, and a penetrating circular groove is formed at the top of the fixing plate 14 , and the bottom of the fixing rod 12 is movably connected to the inside of the circular groove of the fixing plate 14 .

[0033] Furthermore, the four telescopic devices all include a limiting rod 7, a spring piece 8 and a limiting column 9. The second guardrail support rod 6 is internally fixedly connected to the limiting rod 7. The top of the limiting rod 7 corresponds to the second guardrail support rod 6 and is fixedly connected to the inside of the second guardrail support rod 6. Both ends of the spring piece 8 are fixedly connected to two limiting columns 9, and the two limiting columns 9 are movably connected to the inside of the limiting hole 10.

[0034] Furthermore, the spring piece 8 is V-shaped, and one end of the two limiting columns 9 respectively passes through one side of the second guardrail support rod 6 and is fixedly connected to the two ends of the spring piece 8, and the movable ends of the two second guardrail support rods 6 are semicircular.

[0035] Working principle: When the guardrail needs to be used for construction warning, first lift the guardrail top plate 3 upward, so that the guardrail top plate 3 drives the four first guardrail support rods 5 and the four second guardrail support rods 6 to perform circular motion around the movable plate 18 through the four connecting blocks 4 fixedly connected at the bottom thereof, so that the four first guardrail support rods 5 and the four second guardrail support rods 6 are perpendicular to the guardrail bottom plate 1 and the guardrail top plate 3 to form a guardrail, thereby providing warning protection for construction danger areas and preventing workers from entering the construction danger areas and causing injuries due to the lack of obstacles. When the guardrail top plate 3 drives the four first guardrail support rods 5 and the four second guardrail support rods 6 to be perpendicular to the guardrail bottom plate 1, the bottom of the fixed rod 12 passes through the inclined end of the fixed plate 14 and The elasticity of the spring 13 allows the fixing rod 12 to be snapped into the circular groove of the fixing plate 14, so that the guardrail is in a fixed state. When the guardrail needs to be folded, the folding handle 11 is first pressed, and then the vertical end of the folding handle 11 is moved upward inside the sleeve 16 through the lateral end, so that the top of the folding handle 11 squeezes the spring 13 while its bottom drives the fixing rod 12 to leave the circular groove of the fixing plate 14, and then pulls the guardrail top plate 3 backward, so that the guardrail top plate 3 drives the second guardrail support rod 6 to rotate around the movable plate 18, so that the second guardrail support rod 6 drives the first guardrail support rod 5 to fold on the guardrail bottom plate 1, thereby reducing the space occupied by the guardrail and making it easy to store the guardrail in a narrow place.

[0036] When the height of the guardrail needs to be adjusted, the first guardrail support rod 5 is first pulled up so that the two limit columns 9 pass through the arc of their movable ends, so that the two limit columns 9 slide out of the limit holes 10 while squeezing the spring pieces 8. Then, when the two limit columns 9 slide to the limit holes 10 at the lower end along the inner wall of the first guardrail support rod 5, the elasticity of the spring pieces 8 is utilized to make the two limit columns 9 enter the interior of the lower limit holes 10, thereby realizing the increase in the height of the guardrail. Conversely, the first guardrail support rod 5 is pulled down to reduce the height of the guardrail, thereby realizing the adjustment of the height of the guardrail.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
