Description

Technical Field

[0001] The utility model relates to the field of supporting components, in particular to a high-efficiency enhanced anchor rod. Background Art

[0002] In construction tunnels such as culverts, mines, and subways, anchor support is widely used to prevent the surrounding rock from falling off and protect the lives of on-site construction workers. The seam pipe anchor is the main component for support. The seam pipe anchor is favored by many users because of its convenience, light weight, and mechanized construction. The traditional seam pipe anchor has a structure including a rod body, which is a hollow tubular structure with an opening on the side, and a retaining ring fixed on the outer surface of the tail end of the rod body.

[0003] The anchor rod of the above structure can play the role of anchoring and supporting. However, since the seam tube only generates elastic tension by the side opening and is in a straight state as a whole, the tension is limited, so that the anchoring force of the anchor rod is low, so that it is constrained during use. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a high-efficiency enhanced anchor rod, which can solve the problem that the existing seam pipe anchor rod only generates elastic tension through the side opening and is in a straight state as a whole with limited tension, resulting in low anchoring force of the anchor rod and causing it to be constrained during use.

[0005] To achieve the above object, the utility model provides the following technical solutions: an efficient enhanced anchor rod, comprising a rod body, the rod body is a hollow structure as a whole, a continuous groove is axially provided on one side of the rod body, and the vertical section of the groove is a V-shaped structure with a side opening;

[0006] The front end of the rod body is provided with an anchor rod head, which is a conical structure with a small front and a large rear;

[0007] The rear end of the rod body is provided with an anchor rod tail, and the anchor rod tail is a tapered structure with a small front and a large rear;

[0008] A retaining ring is fixedly provided on the outer surface of the anchor rod tail, and a tray is sleeved on the front side of the retaining ring.

[0009] As a preferred technical solution, the rod body is formed by rolling a seamless steel pipe.

[0010] As a preferred technical solution, the inner cavity of the rod body is an annular sealing structure.

[0011] As a preferred technical solution, the front end portion of the anchor rod head is inclined toward one side of the groove.

[0012] As a preferred technical solution, the rear end of the anchor rod is inclined toward one side of the groove.

[0013] As a preferred technical solution, the depth of the groove gradually decreases from the front end to the rear end of the rod body.

[0014] Compared with the prior art, the utility model provides a highly efficient enhanced anchor rod, which has the following beneficial effects:

[0015] 1. The utility model is provided with a continuous groove axially on one side of the rod body, and the vertical section of the groove is a V-shaped structure with a side opening. When in use, the V-shaped groove structure allows the rod body to shrink and deform on the inner wall of the drill hole, ensuring that the rod body is tightly combined with the drill hole. Compared with the side opening of the seam pipe, a stronger friction force is generated, which plays a role in enhancing the strong anchoring, and no anchoring agent is required, and the installation is quick and efficient.

[0016] 2. The utility model is provided with an anchor head at the front end of the rod body, and the anchor head is a tapered structure that is small at the front and large at the rear; an anchor tail is provided at the rear end of the rod body, and the anchor tail is a tapered structure that is small at the front and large at the rear; a retaining ring is fixedly provided on the anchor tail, and a tray is also sleeved on the front side of the retaining ring. When in use, the tapered anchor head and anchor tail can gradually increase the tension of the rod body from front to back during installation, so that the rod body as a whole has better anchoring force, and the retaining ring and the tray can play a supporting role at the rear end.

[0017] 3. The utility model has a rod body that is rolled from a seamless steel tube, and the tensile strength per unit cross-sectional area is much higher than that of an ordinary anchor rod; the inner cavity of the rod body is an annular sealing structure, and when in use, the inner cavity of the rod body can be grouted after the anchor rod is installed, which can both increase the strength of the rod body and protect the rod body from corrosion.

[0018] 4. The utility model tilts the front end of the anchor rod head toward one side of the groove, and the rear end of the anchor rod tail toward one side of the groove. When in use, the rod body needs to overcome the tilting state of the anchor rod head and the anchor rod tail to be straightened during installation, thereby enhancing the friction between the rod body and the inner wall of the borehole, and further increasing the anchoring force between the rod body and the borehole.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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. Example 1

[0027] like Figures 1 to 5 As shown, a high-efficiency enhanced anchor rod comprises a rod body 2, the rod body 2 is a hollow structure as a whole, a continuous groove 21 is axially provided on one side of the rod body 2, and the vertical section of the groove 21 is a V-shaped structure with a side opening. An anchor rod head 1 is provided at the front end of the rod body 2, and the anchor rod head 1 is a conical structure with a small front and a large rear. An anchor rod tail 4 is provided at the rear end of the rod body 2, and the anchor rod tail 4 is a conical structure with a small front and a large rear. A retaining ring 3 is also fixedly provided on the outer surface of the anchor rod tail 4, and a matching tray (not shown in the figure) is also sleeved on the front side of the retaining ring 3.

[0028] The rod body 2 is formed by rolling a seamless steel pipe, and the inner cavity of the rod body 2 is an annular sealing structure.

[0029] The front end of the anchor head 1 is inclined toward the groove 21. The rear end of the anchor tail 4 is inclined toward the groove 21.

[0030] The depth of the groove 21 gradually decreases from the front end to the rear end of the rod body 2 .

[0031] When in use, the V-shaped groove 21 structure allows the rod body 2 to shrink and deform on the inner wall of the borehole, ensuring that the rod body 2 is tightly combined with the borehole, generating stronger friction than the side opening of the seam pipe, enhancing the anchoring effect, and no anchoring agent is required, so the installation is quick and efficient. The conical anchor head 1 and anchor tail 4 allow the rod body 2 to gradually increase the tension of the rod body 2 from front to back during installation, so that the rod body 2 as a whole has better anchoring force, and the retaining ring 3 and the tray can play a supporting role at the tail end. When installing the rod body 2, it is necessary to overcome the tilted state of the anchor head 1 and the anchor tail 4 to straighten it, enhance the friction between the rod body 2 and the inner wall of the borehole, and further increase the anchoring force between the rod body 2 and the borehole. After the anchor is installed, the inner cavity of the rod body 2 can be grouted, which can both increase the strength of the rod body 2 and protect the rod body 2 from corrosion.
