[0004] The above-mentioned existing technical solutions have the following defects: when the guardrail needs to be installed on a slope, since the base design may only consider the situation of the flat ground, and no special stability design is made for the slope, the guardrail may be installed unsteadily on the slope, and it may be easy to slide or tilt. When subjected to external forces, such as wind and rain, human touch, etc., there are great safety hazards. Especially in situations where the terrain is complex or special protection is required, the angle of the guardrail may need to be adjusted to meet different needs.

[0005] Therefore, we propose a reusable guardrail for engineering construction to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a reusable guardrail for engineering construction, so as to solve the problems in the above-mentioned background technology that the angle of the guardrail cannot be adjusted and the guardrail is unstable when installed on a slope.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reusable guardrail for engineering construction, comprising a support column and a guardrail, wherein a rotating connection mechanism is arranged on the outer side of the support column, and a fixing mechanism is arranged on the bottom of the guardrail;

[0010] Preferably, the guardrail is fixedly connected with a clamping block around its periphery, the clamping block is provided with a second placement groove inside, and a second connection hole is provided on the surface of the clamping block. The design of the clamping block helps to enhance the overall structural stability of the guardrail, ensuring that it is not easily deformed or damaged when subjected to external forces. At the same time, the second placement groove and the second connection hole inside the clamping block provide a fixed position for the connector, making the connection between the guardrail and the support column more stable.

[0011] Preferably, there are four rotating connection mechanisms, which are respectively arranged at the upper and lower positions on both sides of the support column, which can ensure that the guardrail has better stability and uniform force when connected.

[0012] Preferably, the connection hole 1 and the connection hole 2 have the same diameter, and the connector and the block are connected by a fastener.

The fixing plate 1 and the fixing plate 2 are fixedly connected to the two sides of the support column, and the telescopic rod is movably connected to the side of the fixing plate 1 and the fixing plate 2 that are close to each other through the connecting bar. The auxiliary support structure provides additional support force for the support column through the telescopic rod and the connecting bar, thereby enhancing the bearing capacity and stability of the support column. When subjected to external force or wind force, the auxiliary support structure can effectively prevent the support column from tilting or collapsing, thereby ensuring the safety of the entire guardrail system.

[0015] Preferably, a plurality of equally spaced protective strips are fixedly connected to the top of the guardrail, and the design of the protective strips can increase the protective performance of the guardrail and prevent people or objects from climbing over or falling from the top of the guardrail.

The placement groove 502 and the connection hole 501 inside the clamping block 5 provide an installation position for the fastener 8, so as to ensure a firm connection between the guardrail 3 and the support column 1. A rotating connection mechanism is provided on the outer side of the support column 1, and a plurality of equidistant protection strips 9 are fixedly connected to the top of the guardrail 3, and a fixing mechanism is provided at the bottom of the guardrail 3;

[0027] The rotating connection mechanism includes a placement slot 101, a transfer bar 102, a connector 2 and a connection hole 201. The placement slot 101 is opened on the outside of the support column 1. The connector 2 is rotatably connected to the inside of the placement slot 101 through the transfer bar. The connection hole 101 is opened in the middle of the connector 2. The diameters of the connection hole 101 and the connection hole 201 are the same, and the connector 2 and the block 5 are connected by a fastener 8. There are four rotating connection mechanisms, which are respectively arranged at the upper and lower positions on both sides of the support column 1, allowing the guardrail 3 to rotate at a certain angle on the support column 1, so as to adapt to different usage scenarios and needs. At the same time, the connector 2 and the block 5 are connected together by the fastener 8, which enhances the stability and safety of the connection.

[0028] The fixing mechanism includes a ground nail 4, a cylinder 601, a connecting plate 602 and a slide 603. The slide 603 is opened on both sides of the lower interior of the guardrail 3. Slide blocks are fixedly connected to both sides of the connecting plate 602. The slide blocks are slidably connected to the slide 603.

There are multiple cylinders 601 and ground nails 4, respectively, and they are fixedly connected to the upper and lower sides of the connecting plate 602 at equal distances. This mechanism enables the guardrail 3 to be firmly fixed on the ground to prevent movement or tipping due to wind or other external forces. The design of the cylinder 601 makes the insertion and removal process of the ground nail 4 more convenient and efficient, improving work efficiency.

[0029] Auxiliary support structures are provided on the front and rear sides of the support column 1, and the auxiliary support structures include a fixing plate 1 701, a fixing plate 2 703, a connecting bar 702102 and a telescopic rod 704.

[0030] Working principle: First, the guardrail 3 is connected to the support column 1 through the clamping block 5, and the fastener 8 is passed through the connection hole 1 201 and the connection hole 2 502 to fix the connector 2 and the clamping block 5 together. When the guardrail angle needs to be adjusted, the guardrail 3 can be rotated inside the placement slot 1 101 by operating the adapter bar 102 and the connector 2 to adapt to different usage scenarios and needs.

[0031] Ensure that the guardrail 3 is in a suitable position and angle, start the cylinder 601, and drive the ground spike 4 to penetrate the ground to fix the guardrail 3. According to the terrain conditions and stability requirements, the extension degree of the cylinder 601 can be adjusted to ensure that the ground spike 4 is inserted to an appropriate depth. After the guardrail 3 is installed, it can be used. During use, regularly check the stability and integrity of the guardrail to ensure that there are no loose or damaged parts.

[0032] When the guardrail needs to be disassembled or moved, the air cylinder 601 is first operated to pull the ground spike 4 out of the ground. Then, the connection of the fastener 8 is released to remove the guardrail 3 from the support column 1. The above steps can be repeated for assembly and use as needed.
