Referring to the attached drawings 1-11, the variable-diameter grouting anchoring device provided by the invention comprises a fixed shaft 2, a movable sleeve 5 and an expanding assembly. The movable sleeve 5 is sleeved on the periphery of the fixed shaft 2, and a moving pair is formed between the movable sleeve 5 and the fixed shaft 2. The expanding assembly comprises a first movable connecting piece 17, an expanding rod 12 and a third movable connecting piece 19, wherein one end of the first movable connecting piece 17 is hinged to the movable sleeve 5, and the other end of the first movable connecting piece 17 is hinged to the expanding rod 12. One end of the third movable connecting piece 19 is hinged on the fixed shaft 2, and the other end of the third movable connecting piece 19 is hinged on the diameter enlarging rod 12. The expanding assembly comprises a plurality of groups, and the expanding assembly is arranged on the periphery of the movable sleeve along the circumferential direction of the movable sleeve 5.
When the borderline grouting anchoring device provided by the invention is applied to grouting operation, as the movable sleeve 5 moves downwards relative to the fixed shaft 2, one end of the first movable connecting piece 17 is hinged to the movable sleeve 5, so that the hinged point of the first movable connecting piece 17 and the movable sleeve 5 also moves downwards relative to the fixed shaft 2 along with the movable sleeve 5, at the moment, under the hinged limiting action between the third movable connecting piece 19 and the fixed shaft 2, the first movable connecting piece 17 rotates anticlockwise by taking the hinged point between the first movable connecting piece 17 and the movable sleeve 5 as a rotation center, the third movable connecting piece 19 rotates clockwise by taking the hinged point between the third movable connecting piece 19 and the fixed shaft 2 as a rotation center, and as a result, the expanding rod 12 is propped by the first movable connecting piece 17 and the third movable connecting piece 19 to realize expanding diameter, therefore, the borderline grouting anchoring device provided by the invention can realize expanding in the construction process, the diameter of the anchoring device is expanded as required. In this embodiment, in order to ensure the hinge effect between the third movable connecting element 19 and the fixed shaft 2, a first fixed connecting element 10 may be further disposed on the fixed shaft 2, wherein the first fixed connecting element 10 is fixedly connected to the fixed shaft 2, so that there is no relative movement between the first fixed connecting element 10 and the fixed shaft 2, and a hinge point between the third movable connecting element 19 and the fixed shaft 2 is disposed on the first fixed connecting element 10.
The diameter expanding assembly further comprises a second movable connecting piece 18, one end of the second movable connecting piece 18 is hinged to the movable sleeve 5, the other end of the second movable connecting piece 18 is hinged to the diameter expanding rod 12, and a hinge point between the second movable connecting piece 18 and the diameter expanding rod 12 and a hinge point between the third movable connecting piece 19 and the diameter expanding rod 12 are the same hinge point. In this case, when the movable sleeve 5 moves downward relative to the fixed shaft 2, the spreading force applied to the diameter-expanding rod 12 by the second movable connecting piece 18 and the third movable connecting piece 19 is more stable, and the diameter-expanding operation by the diameter-expanding rod 12 is more stable. In practice, the expanding assembly may also comprise a plurality of intermediate mobile connectors (not shown), one end of which is hinged to the mobile sleeve 5 and the other end of which is hinged to the expanding rod 12, in which case the stress points of the expanding rod 12 can be increased, thus further improving its stability to opening.

In this case, the variable-diameter grouting anchoring device provided by the invention can be externally connected through the mandrel 1 with threads.
Wherein, but reducing slip casting anchor still includes slip casting pipe 3 and slip casting container 7. The position between the grouting pipe 3 and the fixed shaft 2 is relatively fixed, the position between the grouting container 7 and the movable sleeve 5 is relatively fixed, and the grouting pipe 3 is communicated with the grouting container 7 through a central through hole thereof; a moving pair is formed between the grouting pipe 3 and the grouting container 7, and when the slurry is poured from the grouting pipe 3, the slurry enters the grouting container 7 from the grouting pipe 3. In this embodiment, the grouting pipe 3 is fixedly connected to the fixed shaft 2 through a second fixed connecting member 4. In this case, when the slurry is injected through the injection pipe 3, the injection container 7 moves downward relative to the injection pipe 3 as the injection volume of the slurry in the injection container 7 increases, and at this time, since the position between the injection container 7 and the movable sleeve 5 is relatively fixed, the movable sleeve 5 moves downward relative to the fixed shaft 2 as the injection volume of the slurry in the injection container 7 increases, that is, the injection operation can provide an acting force for the diameter expanding action by the diameter expanding rod 12, and in this case, the diameter expanding action by the diameter expanding rod 12 can be achieved without applying a downward acting force relative to the fixed shaft 2 to the movable sleeve 5 by other external forces, and not only the working efficiency is improved, but also the manpower resources can be saved.
The bottom of the side wall of the grouting pipe 3 is provided with a grout overflow hole 20, wherein the grout overflow hole 20 is completely positioned below the upper edge of the grouting container 7 before the diameter-expanding rod 12 is expanded to be ready; when the expanding rods 12 are spread out ready, the grout outlet 20 is at least partially above the upper edge of the grouting container 7.

The transverse flexible reinforcing ribs 13 are wound on the periphery of the diameter-expanding rod 12 along the circumferential direction. When the expanding action of the diameter expanding rod 12 is realized only by the action of the first movable connecting piece 17, the second movable connecting piece 18 and the third movable connecting piece 19, the diameter expanding effect between the connecting points is poor easily because the connecting points between the diameter expanding rod 12 and the first connecting piece 17, the second connecting piece 18 and the third connecting piece 19 are few, and after the transverse flexible reinforcing ribs 13 are introduced, the diameter expanding action points of the diameter expanding rod 12 can be encrypted, so that the diameter expanding effect of the diameter expanding rod 12 is better and more reliable.
The variable-diameter grouting anchoring device further comprises a bearing plate 8, the bearing plate 8 is fixedly connected to the movable sleeve 5, and the grouting container 7 is borne above the bearing plate 8. In this case, the tray 8 is used to transmit the downward movement of the grouting container 7 relative to the grouting pipe 3, and at this time, as the grouting container 7 moves downward relative to the grouting pipe 3, the tray 8 is pushed to move downward relative to the grouting pipe 3, and the movable sleeve 3 also moves downward relative to the fixed shaft 2, so that the first movable connecting member 17 and the third movable connecting member 19 can smoothly apply the expanding force to the diameter expanding rod 12. In this embodiment, slip casting container 7 is through its bottom fixed connection in the upper surface that bears dish 8, for example, can be for the welding, or slip casting container 7 bottom sets up has the internal screw thread blind hole, and the upper surface that bears dish 8 is equipped with the spliced pole, be equipped with on this spliced pole can with the external screw thread of this internal thread looks adaptation, under this condition, through this have the internal screw thread blind hole and with the external screw thread of this internal thread looks adaptation, can make slip casting container 7 can fix to the upper surface that bears dish 8.

In this case, the connection between the first movable connecting element 17 and the movable sleeve 5 is realized by the hinge plate 6, and the connection between the second movable connecting element 18 and the movable sleeve 5 is realized by the bearing plate 8, so that the connections between the first movable connecting element 17, the second movable connecting element 18 and the movable sleeve 5 are more reliable. Wherein, the variable diameter grouting anchoring device also comprises an outer cover 14, an upper connecting piece 15 and a lower connecting piece 16. The outer cover 14 covers the outside of the diameter expanding rod 12; the upper part of the outer cover 14 is fixedly connected to the mandrel 1 through an upper connecting piece 15; the lower part of the housing 14 is fixedly connected to the stationary shaft 2 by means of a lower connecting piece 16.
