[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a steel strand anchoring device includes: a U-shaped frame 1, characterized in that: a pad 2 is fixed on the top of the U-shaped frame 1, a drill rod 3 is rotatably connected to the inside of the U-shaped frame 1, the bottom of the drill rod 3 is a drill cutter, and the drill cutter is made of an alloy material with high hardness. The top of the drill rod 3 passes through the pad 2, and a turntable 4 is fixed on the top of the drill rod 3. The outer surface of the U-shaped frame 1 is provided with a thread 5, and the outside of the drill rod 3 is slidably provided with a support seat 6.

[0023] In this embodiment, the turntable 4 is rotated and the rod 3 is lowered. When the rod 3 is lowered, it penetrates into the interior of the soil layer, which is beneficial to fix the anchoring device.

[0024] See also Figures 1 to 4 The outside of the U-shaped frame 1 is rotatably connected to a nut 7 through a thread 5, a wire groove 8 is provided on the top of the support seat 6, and a limiting slot 9 is provided on the top of the U-shaped frame 1. The bottom of the pad 2 is fixed with a vertical plate 11, and a round hole 12 is provided at the bottom of the vertical plate 11. A cylinder 13 is fixedly installed on the top of the pad 2, and the pad 2 is slidably connected to the vertical block 14 in the vertical direction. The back of the pad 2 is rotatably connected to a connecting rod 15, and the back of the pad 2 is slidably connected to a clamping rod 16 in the horizontal direction. One end of the connecting rod 15 is rotatably connected to the vertical block 14, and the other end of the connecting rod 15 is rotatably connected to the clamping rod 16. There are four connecting rods 15 in total, and two clamping rods 16 in total. Two connecting rods 15 correspond to one clamping rod 16. The bottom of the clamping rod 16 is arc-shaped, and an anti-slip pad is provided at the arc of the clamping rod 16.

[0025] In this embodiment: the end of the steel strand that needs to be anchored is passed through the wire groove 8 on the top of the support seat 6, and simultaneously passed through the circular hole 12. At this time, one end of the steel strand is located between the wire groove 8 and the limit groove 9, and is located inside the circular hole 12. Then the nut 7 is turned by a wrench. Under the action of the thread 5, the nut 7 is raised on the outside of the U-shaped frame 1. When the U-shaped frame 1 is raised, the support seat 6 is raised with it. When the support seat 6 is raised, the distance between the wire groove 8 and the limit groove 9 becomes smaller and smaller. Then the wire groove 8 and the limit groove 9 firmly clamp the steel strand, which is conducive to the first anchoring of the steel strand. After that, the output end of the cylinder 13 retracts and raises the vertical block 14 on the back of the vertical plate 11. When the vertical block 14 is raised, the two clamping rods 16 are driven by the connecting rod 15 to rotate in the opposite direction to achieve the second anchoring of the steel strand.

[0026] Working principle: This anchoring device can be inserted into hard soil for anchoring. Turn the turntable 4 and then the rod 3 will drop. When the rod 3 drops, it will penetrate into the soil layer, which is conducive to fixing the anchoring device.

[0027] The end of the steel strand that needs to be anchored passes through the wire groove 8 on the top of the support seat 6, and passes through the circular hole 12 at the same time. At this time, one end of the steel strand is located between the wire groove 8 and the limiting groove 9, and is located inside the circular hole 12. Then, the nut 7 is turned by a wrench. Under the action of the thread 5, the nut 7 rises on the outside of the U-shaped frame 1. When the U-shaped frame 1 rises, the support seat 6 rises with it. When the support seat 6 rises, the distance between the wire groove 8 and the limiting groove 9 becomes smaller and smaller. Then the wire groove 8 and the limiting groove 9 firmly clamp the steel strand, which is conducive to the first anchoring of the steel strand.

[0028] Afterwards, the output end of the cylinder 13 retracts and raises the vertical block 14 on the back of the vertical plate 11. When the vertical block 14 rises, the connecting rod 15 drives the two clamping rods 16 to rotate in the opposite direction to achieve a second anchoring of the steel strand. The above two anchorings are beneficial to improving the clamping effect of the steel strand.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
