Technical Field
[0001] This utility model relates to the field of anchor cable and anchorage technology, specifically to an anti-slip anchor cable and anchorage. Background Technology
[0002] In geotechnical engineering and underground space development, anchor cables are widely used as an important reinforcement method for slope stabilization, foundation pit support, and tunnel lining. However, in practical applications, factors such as complex and variable underground conditions leading to anchor rust and the entry of mortar into the anchors due to underground shotcreting construction processes can cause the locking resistance of the clamping plates to increase and then slide down, resulting in anchor failure, structural instability, or even collapse accidents, posing a great threat to engineering safety.
[0003] To overcome the above problems, researchers at home and abroad have proposed a variety of improved anchor design schemes in recent years, such as self-locking and expansion anchors. Although these schemes have improved the safety and reliability of anchors to a certain extent, they generally have problems such as complex structure, high cost and limited application scope, making it difficult to meet the growing market demand.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.
[0026] In practical applications, factors such as complex and variable underground conditions leading to anchor rust and the grouting process in underground wells causing mortar to enter the anchor can increase the resistance of the wedge locking and cause it to slide down, resulting in anchor failure, structural instability, or even collapse, posing a great threat to engineering safety.
[0027] To overcome the above problems, researchers at home and abroad have proposed a variety of improved anchor design schemes in recent years, such as self-locking and expansion anchors. Although these schemes have improved the safety and reliability of anchors to a certain extent, they generally have problems such as complex structure, high cost and limited application scope, making it difficult to meet the growing market demand.
[0028] Therefore, there is an urgent need for a simple, practical, and high-performance anti-slip anchor to address the shortcomings of existing technologies.
[0029] The design concept of this application is to design a simple and practical anti-slip anchor cable. This solution adds an anti-slip structure and a protective structure. The anti-slip structure increases the friction coefficient of the anchor ring and the wedge, while the protective structure effectively improves the sealing performance of the anchor, slows down the rusting process of the anchor, and prevents mortar from entering.
[0030] Example 1
[0031] like Figure 1 As shown, this application provides an anti-slip anchor cable anchor, including an anchor cable 1 and an anchor body. The anchor body includes an anchor ring 2, a clamping plate 3, and a steel wire ring 4. The outer wall of the clamping plate 3 is provided with internal teeth 5, which abut against the inner wall of the conical hole of the anchor ring 2. The anchor ring 2 is connected to a protective cover 6, and a butterfly spring 7 is provided on the inner side of the protective cover 6. The butterfly spring 7 abuts against the clamping plate 3.
[0032] The anchor body is mainly composed of an anchor ring 2, three (anchor) clamps 3, and a steel wire ring 4. The anchor ring 2 and the three (anchor) clamps 3 are all made of alloy steel. The inner conical hole of the anchor ring 2 is matched with the outer conical of the clamp 3 with internal teeth 5. The friction coefficient is increased by the internal teeth 5 of the positive pressure clamp 3, so that the steel strand (anchor cable 1) is anchored and cannot retract.
[0033] The anchor ring 2 has an external thread 31 on its outer side wall, and the external thread 31 is threadedly connected to the protective cover 6.
[0034] The protective cover 6 has a convex shape, and the inner wall of the large end of the protective cover 6 is provided with an internal thread that mates with the external thread 31. The small end of the protective cover 6 is connected to the anchor cable 1.
[0035] When in use, simply thread the protective cover 6 onto the anchor ring 2; in addition to threaded installation, the protective cover 6 and the anchor ring 2 can also be connected by welding. The user can decide which connection method to use based on their own situation.
[0036] The cavity between the protective cover 6 and the anchor ring 2 is filled with anti-rust grease; the anti-rust grease can not only prevent the anchor from rusting inside, but also further block the intrusion of mortar during shotcreting.
[0037] Example 2
[0038] The biggest difference between this embodiment and the above embodiments lies in the structure of the small end of the protective cover 6, such as... Figure 2As shown, the small end of the protective cover 6 is provided with a concave arc shell 8, and a ball notch 9 is slidably disposed inside the concave arc shell 8. The anchor cable 1 passes through the ball notch 9, the concave arc shell 8, the butterfly spring 7 and the clamping plate 3 in sequence from the outside to the inside.
[0039] The ball notch 9 is connected to a spring 10, which is connected to the protective cover 6. At least four springs 10 are evenly arranged circumferentially, which is more conducive to the uniformity of the movement of the ball notch 9.
[0040] When in use, the ball notch 9 can swing with the anchor cable 1, which can better reduce the wear of the anchor cable 1 and the protective cover 6.
[0041] First, install the product using the conventional method. Then, insert the disc spring 7, tighten it with a Newton's wrench to compress the disc spring, and finally install the protective cover 6.
[0042] The protective cover 6 can effectively improve the sealing performance of the anchor and block the mortar during spraying. Furthermore, the inside of the anchor is coated with anti-rust grease to prevent the anchor ring 2 and the wedge 3 from failing to anchor. The butterfly spring 7 inside the protective cover 6 can change the wedge 3 from passive following to active following, thus improving the self-locking performance of the anchor product.
[0043] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
