AI Technical Summary
The existing anchor rod has a simple structure and a single function. It cannot cope with holes of different depths and cannot reinforce the concrete injected into the drilled hole, resulting in the concrete being easily broken when soil is extruded.
An anchor construction device is designed, including drill rods, connecting sleeves, drill bits, sleeves and reinforcement components. The reinforcement component is composed of multiple sets of struts, annular rods, movable grooves and springs. Through the action of rebound elastic force, the annular rod expands and fits the inner wall of the borehole, providing reinforcement support for the concrete.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-6 , the utility model provides an embodiment: an anchor construction device, including a drill rod 1;
[0022] The left end of the drill rod 1 is provided with a connecting sleeve 2 through a thread, a drill bit 3 is provided at the left end of the connecting sleeve 2, four groups of protrusions 4 are provided in an annular manner at the left end of the connecting sleeve 2, and the four groups of protrusions 4 are inserted into the right end of the drill bit 3. A sleeve 5 is inserted into the drill rod 1, and a reinforcement component is provided in an annular manner on the sleeve 5. The reinforcement component fits in the drill rod 1. The device inserts the reinforcement component into the drill rod 1, and inserts the reinforcement component into the borehole through the drill rod 1, the connecting sleeve 2 and the drill bit 3, and reinforces the concrete injected into the borehole through the reinforcement component;
[0023] Furthermore, the reinforcement assembly includes multiple groups of support rods 6, which are annularly installed on the outer wall of the sleeve 5. First movable grooves 7 are opened in the multiple groups of support rods 6, springs 8 are installed in the multiple groups of first movable grooves 7, movable rods 9 are movably inserted in the multiple groups of first movable grooves 7, and annular rods 10 are installed on the multiple groups of movable rods 9. When this structure pulls the drill rod 1 and the connecting sleeve 2 out of the sleeve 5, the multiple groups of annular rods 10 and the multiple groups of movable rods 9 pop out and fit against the inner wall of the borehole under the action of the restoring elastic force of the multiple groups of springs 8, and the reinforcement support in the concrete can be shaped by the sleeve 5 and the multiple groups of annular rods 10.
[0024] Furthermore, multiple groups of annular rods 10 are each provided with a second movable groove 11, and multiple groups of second movable grooves 11 are each installed with a first connecting rod 12. The first connecting rods 12 in multiple groups of second movable grooves 11 are interconnected. This structure connects multiple groups of annular rods 10 in an annular manner through multiple groups of first connecting rods 12, so that when multiple groups of annular rods 10 are expanded, they are connected together through multiple groups of first connecting rods 12 to jointly support concrete.
[0025] Furthermore, the multiple groups of annular rods 10 are provided with plug rods 14 on the side opposite to the inner wall of the drill rod 1. The ends of the multiple groups of plug rods 14 that are in contact with the inner wall of the drill rod 1 are tapered. When the multiple groups of annular rods 10 are expanded to fit the inner wall of the borehole, the multiple groups of plug rods 14 are inserted into the soil, thereby improving the anti-pull-out effect of concrete in the borehole.
[0026] Furthermore, a second connecting rod 13 is fixedly installed between the multiple groups of annular rods 10. This structure connects the multiple groups of annular rods 10 on the left and right ends of the sleeve 5 in series through the second connecting rod 13, thereby improving the connection of the multiple groups of annular rods 10 from left to right on the multiple groups of sleeves 5.

When the drill rod 1 and the connecting sleeve 2 are separated from the sleeve 5, as shown in the figure, the anchor rod 1 and the connecting sleeve 2 are removed from the sleeve 5. Figure 3 and Figure 5 As shown, multiple groups of annular rods 10 and multiple groups of movable rods 9 pop out and expand from multiple groups of first movable grooves 7 under the action of the restoring elastic force of multiple groups of springs 8, and when the multiple groups of annular rods 10 are expanded and opened, they drive multiple groups of first connecting rods 12 to slide from multiple groups of second movable grooves 11, so that after the multiple groups of annular rods 10 are expanded and unfolded, they are connected through multiple groups of first connecting rods 12, and when the multiple groups of annular rods 10 are expanded and unfolded, they drive multiple groups of insertion rods 14 to be inserted into the soil, and concrete is injected into the borehole from the drill rod 1, and the sleeve 5 and the multiple groups of annular rods 10 are wrapped therein, so that the anchor rods can be fixed. The above is the entire working principle of the utility model.
