Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to an anchoring structure for slope protection nets. Background Technology

[0002] Slope protection netting is typically made of high-strength steel wire ropes, forming a mesh structure with a certain degree of flexibility and strength. It is connected to the slope via anchoring devices. When soil loosening or landslides occur on the slope, the netting can distribute the load, restrain the soil, and intercept falling rocks.

[0003] However, the anchoring device used to fix the slope protection net has low connection strength with the slope. When the slope becomes loose or landslides, the slope protection net will transfer the force to the anchoring device after being impacted by the soil or falling rocks. This can easily cause the anchoring device to loosen or even come out of the slope, resulting in the slope protection net losing its protective function for the slope. Summary of the Invention

[0004] This invention addresses the problem of low connection strength between anchoring devices used to connect slope protection nets and slopes; it provides an anchoring structure for slope protection nets that improves the protective effect of the nets on slopes.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] An anchoring structure for slope protection netting includes a cylindrical body. A fixing plate is fitted on the upper part of the outer wall of the cylindrical body, and a cone is connected to the lower end. The structure also includes a top plate and a screw. Top plates are arranged in a ring around the outer wall of the cylindrical body between the pressure plate and the cone. A connecting plate is connected to the inner side of each top plate. The inner end of each connecting plate movably penetrates the circumferential wall of the cylindrical body. Each connecting plate has an inclined hole with its upper end inclined towards the central axis of the cylindrical body. A screw is rotatably provided inside the cylindrical body between the inner ends of multiple connecting plates. The screw is threadedly connected to a drive plate inside the cylindrical body. The drive plate has a U-shaped groove that is movably locked outside the inner end of each connecting plate. A drive rod is installed in the inclined hole of each connecting plate. The two ends of each drive rod extend out of the inclined hole and connect to the U-shaped groove outside the connecting plate.

[0007] Furthermore, the top plate is an arc-shaped plate that protrudes away from the cylinder, and the cone is a cone with its tip pointing downwards and coaxial with the cylinder.

[0008] Furthermore, each of the top plates has a limiting rod spaced from top to bottom on its outer side surface. The limiting rod is an arc-shaped rod formed by bending a right-angled triangular prism. The top surface of the limiting rod is a plane, and the bottom surface is an inclined surface with its upper end away from the corresponding top plate.

[0009] Furthermore, when the inner surfaces of the multiple top plates all contact the outer wall of the cylinder, the multiple top plates are on the same ring and concentric with the cylinder, and the diameter of the circle containing the outer edge of the top surface of the limiting rod is equal to the diameter of the upper end of the cone.

[0010] Furthermore, the width of the U-shaped groove corresponds to the thickness of the connecting plate; the two ends of the drive rod in the left oblique hole are respectively fixedly connected to the front and rear sides of the left U-shaped groove of the drive plate.

[0011] Furthermore, the cylinder is provided with a through hole through which the inner end of each connecting plate moves; the lower end of the screw is rotatably connected to the closed end of the bottom of the cylinder, and the upper end moves through the closed end of the top of the cylinder, with the upper end of the screw connected to a rotating plate.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] Multiple parts of the lower part of the slope protection net pass through the mesh holes of the slope protection net. The cylinder and top plate of the lower part of the pressure plate of the slope protection net extend into the slope body. The slope protection net is limited on the slope by the pressure plate of the slope protection net. The multiple top plates of the slope protection net move away from the cylinder under the rotation of the screw. The multiple top plates can press against the receiving hole on the slope where the cylinder is located, thereby improving the connection strength between the slope protection net and the slope through the slope protection net.

[0014] The limiting rod on the top plate of this utility model can extend into the slope body, thereby improving the tensile strength of this utility model and further enhancing the connection strength between the slope protection net and the slope through this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-5As shown, an anchoring structure for slope protection netting includes a cylindrical body 1, which is a cylinder with both ends sealed by sealing plates. A fixing plate 2 is fitted onto the upper part of the outer wall of the cylindrical body 1, and a cone 3 is connected to the lower end. It also includes a top plate 4 and a screw 5. Top plates 4 are arranged in a ring around the outer side of the cylindrical body 1 between the pressure plate 2 and the cone. A connecting plate 6 is connected to the inner side of each top plate 4, with the inner side of the top plate 4 facing the cylindrical body 1. The connecting plate 6 is a rectangular plate with its inner end away from the top plate 4. The inner end of each connecting plate 6 movably penetrates the circumference of the cylindrical body 1 and is located inside the cylindrical body 1. Each connecting plate 6 has a top end facing the central axis of the cylindrical body 1. An inclined hole 7 is an elongated hole. The lower end of the inclined hole 7 passes through the lower end of the connecting plate 6. The lower end opening of the inclined hole 7 is blocked by a sealing block 11. A screw 5 is rotatably provided inside the cylinder 1, located between the inner ends of multiple connecting plates 6. The screw 5 is threadedly connected to a drive plate 9 inside the cylinder 1. The drive plate 9 is provided with a U-shaped groove 10 that is movable and locked outside the inner end of each connecting plate 6. A drive rod 12 is installed in the inclined hole 7 of each connecting plate 6. The drive rod 12 is a round rod with a diameter matching the width of the inclined hole 7. Both ends of each drive rod 12 extend out of the inclined hole 7 and connect to the U-shaped groove 10 outside the connecting plate 6.

[0023] The top plate 4 is an arc-shaped plate that protrudes away from the cylinder 1, and the cone 3 is a cone with its tip pointing downwards and coaxial with the cylinder 1.

[0024] Each of the top plates 4 has a limiting rod 13 spaced from top to bottom on its outer side surface. The limiting rod 13 is an arc-shaped rod formed by bending a right-angled triangular prism. The top surface of the limiting rod 13 is a plane, and the bottom surface is an inclined surface with its upper end away from the corresponding top plate 4.

[0025] When the inner surfaces of the multiple top plates 4 are in contact with the outer wall of the cylinder 1, the multiple top plates 4 are on the same ring and concentric with the cylinder 1, and the diameter of the circle containing the outer edge of the top surface of the limiting rod 13 is equal to the diameter of the upper end of the cone.

[0026] The drive plate 9 is a circular plate whose circumferential surface slides in contact with the inner wall of the cylinder 1, and the drive plate 9 has a threaded hole in the middle that corresponds to the screw 5.

[0027] The width of the U-shaped groove 10 corresponds to the thickness of the connecting plate 6; the two ends of the drive rod 12 in the left oblique hole 7 are respectively fixedly connected to the front and rear sides of the left U-shaped groove 10 of the drive plate 9.

[0028] The cylinder 1 is provided with a through hole 14 for the inner end of each connecting plate 6 to move through; the lower end of the screw 5 is rotatably connected to the bottom closed end of the cylinder 1, and the upper end moves through the top closed end of the cylinder 1; the upper end of the screw 5 is connected to a rotating plate 15.

[0029] In the initial state, when the screw 5 of this utility model is rotated, the U-shaped groove 10 on the drive plate 9 is limited by the corresponding top plate 4, so the drive plate 9 cannot rotate. When the screw 5 rotates, it drives the drive plate 9 to move downward. Multiple drive rods 12 move downward with the drive plate 9. Each drive rod 12 presses against the inclined hole 7, and the connecting plate 6 where the inclined hole 7 is located moves towards the central axis of the cylinder 1 until the inner side of multiple top plates 4 contacts the outer wall of the cylinder 1.

[0030] In use, the slope protection net 16 is laid on the slope surface. The mesh near the edge of the slope protection net 16 is threaded through. The cone 3, the cylinder 1 under the pressure plate 2, and multiple top plates 4 extend into the slope. During the process of the cylinder 1 extending into the slope, the cone 3 facilitates the cylinder 1's penetration into the slope, forming receiving holes on the slope to accommodate the cylinder, cone 3, and multiple top plates 4. Furthermore, since the multiple top plates 4 are in contact with the inner wall of the cylinder 1 at this time, the limiting rod 13 on the top plate 4 does not affect the penetration of the cylinder 1 and the top plate 4 into the slope, until the slope protection net under the pressure plate 2 is fully inserted. 16. Pressed against the slope by the pressure plate 2, the slope protection net 16 is limited; then the screw 5 on each cylinder 1 is rotated in the opposite direction, so that the screw 5 drives the connected drive plate to move upward. The multiple drive rods 12 on the drive plate move upward to press against the corresponding inclined hole 7, and drive the connecting plate 6 where the inclined hole 7 is located to move away from the central axis of the cylinder 1, so that the top plate 4 on the outer periphery of each cylinder 1 presses against the side wall of the receiving hole where the cylinder 1 is located. The multiple limiting rods 13 on the top plate 4 extend into the slope body outside the receiving hole, enhancing the connection between the top plate 4 and the slope body, thereby enhancing the connection strength between the slope protection net and the slope body through this utility model.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
