DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A bladder-type expansion anti-floating anchor comprises an anchor body 1, on which a plurality of fixing rings 2 are fixedly mounted, on which a plurality of support rods 3 are rotatably mounted, and the plurality of fixing rings 2 are arranged on the anchor body 1 every two meters.

[0021] A plurality of fixed plates 4 are fixedly mounted on the fixed ring 2, an arc spring rod 5 is fixedly mounted on the fixed plate 4, the other end of the arc spring rod 5 is fixedly connected to the support rod 3, a positioning block 6 is fixedly mounted on the support rod 3, a positioning hole is provided on the surface of the positioning block 6, a moving ring 7 is vertically slidably mounted on the fixed ring 2 through an elastic component, a plurality of L-shaped locking blocks 8 are fixedly mounted on the moving ring 7, one end of the locking block 8 is inserted in the positioning hole, a moving component for driving the plurality of moving rings 7 to move is provided on the anchor rod body 1, the moving component includes a plurality of mounting blocks 12 respectively fixedly mounted on the plurality of fixed rings 2, a plurality of sliding rods 13 and a plurality of connecting blocks 14, sliding holes are provided on the surfaces of the plurality of mounting blocks 12, each sliding rod 13 is respectively vertically slidably mounted in a plurality of sliding holes on the same vertical line, a plurality of connecting blocks 14 are respectively fixedly mounted on the plurality of sliding rods 13, and the connecting block 14 is fixedly connected to the moving ring 7.

[0022] The center of the arc spring rod 5 coincides with the connection point where the support rod 3 is rotatably mounted on the fixing ring 2. When one end of the locking block 8 is inserted into the positioning hole, the arc spring rod 5 is in a stretched state, and the support rod 3 tends to rotate downward.

[0023] After the anchor rod is inserted into the borehole, multiple sliding rods 13 are driven vertically to move vertically downward, and then the moving ring 7 is driven vertically downward through the connecting block 14. During the movement of the moving ring 7, multiple locking blocks 8 are driven to move vertically downward until one end of the locking block 8 moves out of the positioning hole opened on the surface of the positioning block 6, and then under the action of the elastic force of the arc spring rod 5, multiple support rods 3 are rotated downward until one end of the support rod 3 contacts the inner wall of the borehole, thereby positioning the anchor rod in the middle of the borehole, ensuring that during the grouting process, the anchor rod position does not shift and is always in the middle position, effectively improving the anchor rod fixing force.

[0024] The elastic component includes a plurality of vertical rods 9 vertically fixedly mounted on the fixed ring 2, a plurality of stoppers 10 respectively fixedly mounted on one end of the plurality of vertical rods 9, and a plurality of telescopic springs 11 respectively sleeved on the plurality of vertical rods 9. A plurality of moving holes are opened on the moving ring 7, and the plurality of vertical rods 9 are respectively slidably inserted into the plurality of moving holes. The two ends of the telescopic spring 11 are respectively fixedly connected to the fixed ring 2 and the moving ring 7.

[0025] Under the action of the elastic force of the telescopic spring 11 , the movable ring 7 has a tendency to move vertically upward, thereby driving the plurality of locking blocks 8 to be tightly inserted into the positioning holes.

[0026] A plurality of arc-shaped rods 15 are fixedly installed between the plurality of slide rods 13 . The plurality of slide rods 13 are arranged in a circle with the anchor rod body 1 as the center. The plurality of arc-shaped rods 15 connect the plurality of slide rods 13 together, thereby ensuring that the plurality of slide rods 13 move together.

[0027] A rotation groove is formed at one end of the support rod 3, in which a blocking plate 16 is rotatably mounted. A plurality of barbs 17 are fixedly mounted on the surface of the blocking plate 16, and a counterweight 18 is fixedly mounted on the lower end of the blocking plate 16. The weight of the counterweight 18 is greater than that of the blocking plate 16.

[0028] Under the action of gravity of the counterweight 18, the obstruction plate 16 is ensured to be in a vertical state, so that the obstruction plate 16 is parallel to the inner wall of the borehole. When one end of the support rod 3 contacts the inner wall of the borehole, it will drive the obstruction plate 16 to contact the inner wall of the borehole, and insert multiple barbs 17 into the inner wall of the borehole, thereby increasing the resistance between the support rod 3 and the inner wall of the borehole, making the anchor rod positioning more stable.

[0029] In the utility model, after the anchor rod is inserted into the drill hole, the movable ring 7 is driven by the movable assembly to move vertically downward. During the movement of the movable ring 7, multiple locking blocks 8 are driven to move vertically downward until one end of the locking block 8 is moved out of the positioning hole opened on the surface of the positioning block 6. Then, under the action of the elastic force of the arc spring rod 5, multiple support rods 3 are rotated downward until one end of the support rod 3 contacts the inner wall of the drill hole, thereby positioning the anchor rod in the middle of the drill hole, ensuring that during the grouting process, the anchor rod position does not shift and is always in the middle position, effectively improving the anchor rod fixing force.

[0030] In general, in view of the technical problem: in order to facilitate the insertion of the anchor rod into the drill hole, the diameter of the existing positioner is usually smaller than the diameter of the drill hole, and then during grouting, the anchor rod may still be tilted and misaligned, resulting in a decrease in the anchor rod fixing force; a technical solution is adopted: through the mutual cooperation of the moving assembly, the moving ring 7, the locking block 8, the positioning block 6, the support rod 3, and the arc spring rod 5, the anchor rod can be stably fixed in the drill hole; because the implementation process of the technical solution is: after the anchor rod is inserted into the drill hole, the moving assembly drives the moving ring 7 to move vertically When the movable ring 7 moves downward, the movable ring 7 will drive the multiple locking blocks 8 to move vertically downward until one end of the locking block 8 moves out of the positioning hole opened on the surface of the positioning block 6, and then under the action of the elastic force of the arc spring rod 5, the multiple support rods 3 are rotated downward until one end of the support rod 3 contacts the inner wall of the borehole, thereby positioning the anchor rod in the middle of the borehole; therefore, the technical problem can be solved inevitably, and the technical effect achieved is: ensuring that during the grouting process, the anchor rod position does not shift and is always in the middle position, effectively improving the anchor rod fixing force.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
