[0025] To describe the protective device within this utility model in detail, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Figures 1 to 4 The schematic structures of the protective device and its internal components according to embodiments of the present invention are shown from different angles.

[0027] like Figures 1 to 4 As shown in the figure, the protective device of this utility model embodiment includes at least two protective railing assemblies that are movably connected. Each protective railing assembly includes a left post 1, a right post, and a reinforcing rod disposed between the left post 1 and the right post. The reinforcing rod is used to connect the left post 1 and the right post to form a guardrail structure. A connecting rod 4 is respectively provided on the left post 1 and the right post. During the use of the protective device, multiple protective railing assemblies can be assembled according to the protection requirements of the construction site. The connecting rod 4 between two adjacent protective railing assemblies is movably connected by a fastener. After determining the position and angle of the protective railing assembly, the position of the protective railing assembly can be locked by the fastener, and the bottom of the left post 1 and the right post can be fixed to the ground of the area to be protected, forming a protective device that meets the requirements of the construction site.

[0028] The reinforcing bar between the left post 1 and the right post includes at least two horizontal bars 2 arranged parallel to each other between the left post 1 and the right post, and several vertical bars 3 arranged between each horizontal bar 2; wherein the vertical bars 3 and the horizontal bars 2 are arranged perpendicular to each other; in addition, in order to improve the overall structural strength of the guardrail assembly, an inclined bar can also be set between the left post 1 and the right post. The inclined bar can be set between the horizontal bars 2 and the vertical bars 3 to form a guardrail structure similar to a rhombus or other shapes.

[0029] In addition, to improve the fixing strength between the left post 1 and the right post and the ground, and to ensure that they can effectively play a protective role, a slightly larger polygonal base 5 can be set at the bottom of the left post 1 and the right post. The entire guardrail assembly can be placed on the ground without tilting under the action of the base 5. At the same time, multiple fixing holes 6 are set on the base 5 and the first bolt passes through each fixing hole 6. The base 5 is fixed to the ground by the first bolt, thereby realizing the installation of the guardrail assembly.

[0030] Specifically, multiple fixing holes 6 can be provided on a base 5. The multiple fixing holes 6 are evenly or symmetrically distributed on the base 5 with respect to the uprights (including the left upright 1 and the right upright). The base 5 below the left upright 1 and the right upright is fixed to the ground by the first bolt, thus completing the fixing of a guardrail assembly. The fixing method of other guardrail assemblies is the same.

[0031] To connect multiple guardrails, at least two connecting rods 4 are installed on the left post 1 and the right post respectively. The connecting rods 4 can be fixed to the left post 1 and the right post by bolts or welding, and each connecting rod 4 has a connecting hole. The connecting holes on the connecting rods 4 of two adjacent guardrail components are either vertically or horizontally aligned. In other words, when connecting two guardrail components, the positions of the connecting rods on the right post of one guardrail component and the left post of another guardrail component can be vertically aligned, as shown in the attached diagram. Figure 1 As shown, they can also be horizontally aligned (i.e., left and right aligned), so that the connecting holes on the two connecting rods are in opposite positions, and then the connecting rods are fixedly connected by a fastener.

[0032] It is understood that the structure of each guardrail component can be exactly the same. During the assembly process, the connecting rods of two guardrail components can be horizontally staggered; or the guardrail components can only have differences in the height of the connecting rods, so that the connecting rods of two guardrail components can be connected vertically. This utility model does not specifically limit them.

[0033] The fastener may include a second bolt 7 and a second nut adapted to the second bolt 7. The second nut passes through a connecting hole on the connecting rod between two adjacent guardrail assemblies and is then locked. When it is necessary to adjust the relative angle between the two guardrail assemblies, the second nut can be loosened for adjustment.

[0034] It should be noted that the protective device of this utility model embodiment can be applied to construction sites near wellheads, openings, or foundation pits. In order to better protect such sites, the lengths of the above-mentioned guardrail components can be set to be the same or different. By assembling guardrail components of different lengths, various shapes of protective devices can be formed, thereby improving the flexibility and ease of use of the protective device.

[0035] In the use of the protective device provided by this utility model, firstly, connecting rods with bolt holes are installed on the left and right uprights, and a base part is made below the left and right uprights with pre-drilled fixing holes. Then, the left upright and the upper crossbar are welded together, and the uprights are welded below the crossbar in sequence. After all the uprights are welded, the lower crossbar is welded together, and finally, it is welded to the right upright.

[0036] Then, the second bolt is passed through the bolt holes on the connecting rods on the adjacent sides of the two guardrail assemblies, and then secured with the second nut. Then, the bases of the left and right posts are fixed to the ground with the first bolt, and so on, until the installation of all guardrail assemblies is completed.

[0037] As an example, if the protected area is a road manhole, the orientation of two guardrail components can be adjusted to an acute angle of 60°, and then the connecting rod can be fixed with bolts and nuts. A third guardrail component can then be connected to it. After fixing the bolts and nuts at the other two locations, the first bolt can be placed into the base and secured, thus providing safety protection for the manhole. If the protected area is a bridge edge, a sufficient number of guardrail components need to be arranged sequentially on both sides of the bridge, then bolts and nuts can be fixed. Finally, the base bolts can be secured to provide bridge edge protection.

[0038] According to the above-mentioned protective device of this utility model, multiple protective railing components are set, and the multiple protective railing components can be connected by connecting rods and fasteners. The number of protective railing components used can be flexibly set according to the needs of the construction site, and the angle between each protective railing component can be adjusted arbitrarily. The protective device has a simple structure, is easy to install and disassemble, and can be reused. It can meet the protection needs of construction near edges, well openings, openings or foundation pits.

[0039] The protective device according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the protective device proposed by the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
