Description

Technical Field

[0001] This utility model belongs to the field of landslide control technology, specifically relating to a geological disaster control anchoring device. Background Technology

[0002] Landslides are a natural phenomenon in which soil or rock masses on a slope slide down a weak surface, either as a whole or in smaller pieces, under the influence of gravity. They are primarily triggered by external factors, and their occurrence is usually related to a combination of factors, including natural and human factors. Natural factors such as earthquakes, rainfall, snowmelt, and the scouring and soaking of the slope toe by rivers are common triggers. For example, rainwater seeping into soil or rock fissures can reduce material strength, potentially triggering a landslide. Human factors include unreasonable engineering activities, such as excessive excavation of the slope toe, excessive loading on the slope, and water storage and drainage systems. These activities can undermine slope stability and thus potentially induce landslides.

[0003] In the prior art, Chinese patent with publication number CN222206326U discloses an anchoring device for preventing landslide geological disasters. This prior art uses a triangular block structure to hook the soil, which is relatively complex to adjust and requires pressing down to install the anchor body, making installation laborious. Utility Model Content

[0004] To address the shortcomings of the existing technology, the present invention aims to provide a geological disaster control anchoring device. This device uses spiral blades with opposite thread directions to fix the first and second anchor bodies, resulting in a simpler structure and easier use.

[0005] The technical solution adopted by this geological disaster control anchoring device to solve its technical problems is as follows:

[0006] A geological disaster control anchoring device is provided, including a first anchor body, a drill bit fixedly installed at the lower end of the first anchor body, a first helical blade fixedly installed on the outer periphery of the first anchor body, a second anchor body arranged above the first anchor body, a second helical blade fixedly installed on the outer periphery of the first anchor body, the thread directions of the first helical blade and the second helical blade being opposite, and a connecting structure provided between the first anchor body and the second anchor body, the connecting structure preventing the first anchor body and the second anchor body from rotating relative to each other.

[0007] Furthermore, the connection structure includes a coupling shaft, which is fixedly installed on the top surface of the first anchor body. A square through hole is provided on the second anchor body, through which the coupling shaft passes. A square block that slides and engages with the square through hole is provided inside the square through hole, and the coupling shaft passes through the square block and is provided with a limit structure.

[0008] Furthermore, the limiting structure is a spline groove, the connecting shaft is a spline shaft, the spline groove is opened on the square block, and the connecting shaft passes through the spline groove and cooperates with it.

[0009] Furthermore, a screw is fixedly connected to the top surface of the connecting shaft, and a screw cap is provided on the top of the screw.

[0010] Furthermore, a rotating handle is fixedly installed on the top of the second anchor body.

The user screws the first anchor into the ground by rotation, and then screws the second anchor into the ground in the opposite direction. The first and second anchors are connected by a connecting structure, which prevents the first and second anchors from rotating relative to each other. Because the first and second spiral blades have opposite spiral directions, the first and second anchors cannot be removed from the ground. Compared with the prior art, this utility model uses spiral blades with opposite thread directions to fix the first and second anchors, which is simpler in structure and easier to use.

[0015] 2. A geological disaster control anchoring device according to this utility model can connect the first anchor body and the second anchor body through a connecting shaft and a square block, thereby preventing the first anchor body and the second anchor body from rotating relative to each other.

[0016] 3. The geological disaster control anchoring device of this utility model, compared with other limiting structures, has less restriction on angle by spline shaft and spline groove, which facilitates the installation of square blocks.

[0017] 4. In this utility model example, a geological disaster control anchoring device is provided by screwing the screw cap onto the screw rod, which can protect the top of the second anchor body and prevent the second anchor body from separating from the first anchor body.

[0018] 5. In this utility model example, a geological disaster control anchoring device has a handle that provides a point of leverage for the user, making it easy for the user to rotate the second anchor body.

[0019] 6. In this utility model example, a geological disaster control anchoring device has anti-slip textures that increase the friction between the user and the handle, thereby preventing the hand from slipping.

[0020] 7. In a geological disaster control anchoring device according to this utility model, the gasket can avoid hard contact between the first anchor body and the second anchor body, thereby reducing wear. Attached Figure Description

[0026] like Figure 1 As shown, a geological disaster control anchoring device includes a first anchor body 1, a drill bit 2 fixedly installed at the lower end of the first anchor body 1, a first helical blade 3 fixedly installed on the outer periphery of the first anchor body 1, a second anchor body 5 disposed above the first anchor body 1, and a second helical blade 6 fixedly installed on the outer periphery of the first anchor body 1. The threads of the first helical blade 3 and the second helical blade 6 are opposite in direction. A connecting structure is provided between the first anchor body 1 and the second anchor body 5, preventing the first anchor body 1 and the second anchor body 5 from rotating relative to each other. The user screws the first anchor body 1 into the ground by rotating it, and then screws the second anchor body 5 into the ground in the opposite direction. The connecting structure connects the first anchor body 1 and the second anchor body 5, preventing them from rotating relative to each other. Because the helical directions of the first helical blade 3 and the second helical blade 6 are opposite, the first anchor body 1 and the second anchor body 6 cannot be removed from the ground. Compared with the prior art, this utility model uses helical blades with opposite thread directions to fix the first anchor body 1 and the second anchor body 5, resulting in a simpler structure and easier use.

[0027] like Figure 1As shown, in a further preferred embodiment, the connecting structure includes a connecting shaft 4, which is fixedly installed on the top surface of the first anchor body 1. A square through hole is provided on the second anchor body 5, through which the connecting shaft 4 passes. A square block 8, which slides within the square through hole, is provided. The connecting shaft 4 passes through the square block 8 and is provided with a limiting structure. The first anchor body 1 and the second anchor body 5 can be connected through the connecting shaft 4 and the square block 8, thereby preventing the first anchor body 1 and the second anchor body 5 from rotating relative to each other.

[0028] like Figure 1 As shown, in a further preferred embodiment, the limiting structure is a spline groove, and the connecting shaft 4 is a spline shaft. The spline groove is formed on the square block 8, and the connecting shaft 4 passes through the spline groove and engages with it. Compared with other limiting structures, the spline shaft and spline groove have less restriction on angle, which facilitates the installation of the square block 8.

[0029] like Figure 1 As shown, in a further preferred embodiment, a screw 7 is fixedly connected to the top surface of the connecting shaft 4. The screw 7 is a short screw, and a screw cap 9 is provided on the top of the screw 7. Tightening the screw cap 9 onto the screw 7 can protect the top of the second anchor body 5 and prevent the second anchor body 5 from separating from the first anchor body 1.

[0030] like Figure 1 As shown, in a further preferred embodiment, a handle 10 is fixedly mounted on the top of the second anchor body 5. The handle 10 provides a point of leverage for the user, making it easy for the user to rotate the second anchor body 5.

[0031] like Figure 1 As shown, in a further preferred embodiment, the outer periphery of the handle 10 is provided with anti-slip texture. The anti-slip texture can increase the friction between the user and the handle 10, thereby preventing the hand from slipping.

[0032] like Figure 1 As shown, in a further preferred embodiment, a gasket is provided between the first anchor body 1 and the second anchor body 5. The gasket can prevent hard contact between the first anchor body 1 and the second anchor body 5, thereby reducing wear.
