Description

Technical Field

[0001] This application belongs to the field of fixing device technology, and more specifically, relates to a low-stress anchor rod resin anchoring agent anti-detachment device. Background Technology

[0002] Low-stress anchors refer to anchors that are not subjected to significant prestress during construction or service, or that only bear small tensile forces. Their function mainly relies on the bonding or friction between the anchor body and the soil and rock, rather than actively applied prestress.

[0003] When installing bonded low-stress anchors, drilling is required first. The diameter of the drilled hole should be slightly larger than the diameter of the anchor. Then, high-pressure air or water is used to remove rock powder and water from the hole to ensure the hole wall is clean and to avoid affecting the bonding strength. Then, a cylindrical resin anchoring agent is pushed into the drilled hole. Finally, the anchor is inserted into the drilled hole and the anchoring agent package is punctured, so that the anchoring agent fills the space between the anchor and the hole wall for bonding.

[0004] Generally speaking, the borehole opening is often downward or inclined downward. In order to prevent the resin anchoring agent pack from slipping out of the borehole, an anti-drop device is often needed to fix the resin anchoring agent pack.

[0005] However, in existing anti-detachment devices, the resin anchoring agent packet is inserted into an internal socket, and the two are fixed together by the friction between the packet and the inner wall of the anti-detachment device. When the angle between the drilled hole and the ground is close to 90 degrees, part of the resin anchoring agent packet will detach from the anti-detachment device under the influence of gravity, causing the anti-detachment device to fail. Utility Model Content

[0006] The purpose of this application is to provide a low-stress anchor bolt resin anchoring agent anti-detachment device to prevent the anti-detachment device from failing and to effectively fix the resin anchoring agent package in the borehole.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: a low-stress anchor bolt resin anchoring agent anti-detachment device is provided, comprising a filling body, an mounting body, and a tail wing. The filling body is cylindrical, and the anchoring agent package is inserted into the inner cavity of the filling body. Multiple protrusions are provided on the inner wall of the filling body, and the protrusions are squeezed and embedded in the anchoring agent package. The mounting body is hemispherical and is fastened to one end of the filling body. The tail wing includes multiple tail wings evenly arranged along the circumference of the filling body in the middle of the outer side of the mounting body. The length of the tail wings is greater than the radius of the filling body. When the tail wings are inserted into the anchor hole, they can deform under the action of external force, and the top of the tail wings abuts against the side wall of the anchor hole.

[0008] In one possible implementation, the filling body has multiple perforations evenly distributed on it.

[0010] In one possible implementation, the filling body includes a left half-cylinder and a right half-cylinder, and a plurality of locking mechanisms are provided between the left half-cylinder and the right half-cylinder. The locking mechanisms are evenly arranged along the axial direction of the filling body, and when the locking mechanisms are locked, the left half-cylinder and the right half-cylinder are relatively fixed.

[0011] In one possible implementation, the locking mechanism includes a first connecting plate and a first locking hole. The first connecting plate is disposed on the mating surface of either the left half-cylinder or the right half-cylinder, and a locking block extending along the thickness direction of the first connecting plate is provided at the top end of the first connecting plate. The first locking hole is disposed on the mating surface of the other half-cylinder, and a locking plate is disposed in the first locking hole. The top end of the locking plate is fixed at a position near the opening of the first locking hole. The locking plate is arranged at an angle, and the bottom end of the locking plate blocks the sliding path of the locking block. The locking plate can deform under the action of external force and avoid the locking block. When the first connecting plate is inserted into the first locking hole, the side wall of the first connecting plate abuts against the side wall of the first locking hole, and the bottom end of the locking plate abuts against the end of the locking block.

[0012] In one possible implementation, the locking mechanism includes a second connecting plate and a second locking hole. The second connecting plate is disposed on the mating surface of either the left half-cylinder or the right half-cylinder, and the top of the second connecting plate is provided with a piercing tip. The second locking hole is disposed on the mating surface of the other half-cylinder, and a fixing bladder is provided at the bottom of the second locking hole. The fixing bladder is made of a soft material and contains quick-drying adhesive. When the second connecting plate is inserted into the second locking hole, the piercing tip pierces and inserts into the fixing bladder, so that the quick-drying adhesive fills the space between the second connecting plate and the hole wall of the second locking hole.

[0013] In one possible implementation, the mounting body includes a left half and a right half, the left half being integrally formed at one end of the left half cylinder, and the right half being integrally formed at one end of the right half cylinder. When the left half cylinder and the right half cylinder are fastened together to form the filling body, the left half cylinder and the right half cylinder fasten together to form the mounting body.

[0014] In one possible implementation, a connecting mechanism is provided between the mounting body and the tail fin.

[0015] In one possible implementation, the connecting mechanism includes a left connecting cylinder, a right connecting cylinder, and a connecting rod. The left connecting cylinder is formed on the top of the left half, and has a left large-diameter semi-groove and a left small-diameter semi-groove, which communicate with each other. The left large-diameter semi-groove is located at the end of the left small-diameter semi-groove closer to the filling body. The right connecting cylinder is formed on the top of the right half, and has a right large-diameter semi-groove and a right small-diameter semi-groove, which communicate with each other. The right large-diameter semi-groove is located at the end of the right small-diameter semi-groove near the filling body; when the left half and the right half are fastened together to form the mounting body, the left connecting cylinder and the right connecting cylinder are fastened together to form a connecting cylinder, the left large-diameter semi-groove and the right large-diameter semi-groove are fastened together to form a large-diameter hole, and the left small-diameter semi-groove and the right small-diameter semi-groove are fastened together to form a small-diameter hole; the connecting rod includes a large-diameter section and a small-diameter section that are connected to each other, the top end of the small-diameter section is connected to the tail fin, the large-diameter section is inserted into the large-diameter hole, and the small-diameter section is inserted into the small-diameter hole.

[0016] In one possible implementation, the tail fin has a pointed structure at its tip, and the tip of the pointed structure is arranged outward.

[0017] The beneficial effects of the low-stress anchor resin anchoring agent anti-detachment device provided in this application are as follows: Compared with the prior art, this application enhances the mechanical interlocking force of the filling body on the resin anchoring agent pack by embedding the protrusions on the inner wall of the filling body into the anchoring agent pack, thereby preventing the resin anchoring agent from slipping in extreme environments and thus achieving the purpose of preventing the anti-detachment device from failing. In addition, the hemispherical mounting body can fit more closely with the top of the anchoring agent pack, so that when the protrusion squeezes the side wall of the resin anchoring agent pack, the resin anchoring agent will not cause the pack to deform due to flow and enter the gap between the pack and the mounting body, which is more conducive to the protrusion embedding into the pack. The elastic deformation design of the tail fin allows it to adapt to different hole diameters and provides radial support by pressing the top against the hole wall, further preventing the device from falling off, especially suitable for vertical or large-angle drilling.

[0037] The low-stress anchor rod resin anchoring agent anti-detachment device provided in this application will now be described.

[0038] Please refer to the following: Figures 1 to 8 The low-stress anchor bolt resin anchoring agent anti-detachment device includes a filling body 1, an mounting body 2, and a tail wing 3. The filling body 1 is cylindrical, with the anchoring agent package inserted into its inner cavity. Multiple protrusions 101 are provided on the inner wall of the filling body 1, pressing and embedding the protrusions 101 into the anchoring agent package. The mounting body 2 is hemispherical and is fastened to one end of the filling body 1. The tail wing 3 includes multiple tail wings 301 evenly arranged along the circumference of the filling body 1 on the middle of the outer side of the mounting body 2. The length of the tail wings 301 is greater than the radius of the filling body 1. When the tail wings 301 are inserted into the anchor hole, they can deform under external force, and the top of the tail wings 301 abuts against the side wall of the anchor hole.

[0039] The beneficial effects of the low-stress anchor resin anchoring agent anti-detachment device provided in this embodiment are as follows: Compared with the prior art, the low-stress anchor resin anchoring agent anti-detachment device provided in this embodiment uses the protrusion 101 on the inner wall of the filling body 1 to embed the anchoring agent bag, which enhances the mechanical biting force of the filling body 1 on the resin anchoring agent bag, and avoids the resin anchoring agent from slipping in extreme environments, thereby achieving the purpose of preventing the anti-detachment device from failing. In addition, the hemispherical mounting body 2 can fit more closely with the top of the anchoring agent bag, so that when the protrusion 101 squeezes the side wall of the resin anchoring agent bag, the resin anchoring agent will not deform the bag due to flow and enter the gap between the bag and the mounting body 2, which is more conducive to the protrusion 101 embedding into the bag. The elastic deformation design of the tail fin 3 allows it to adapt to different hole diameters and provides radial support by pressing the top against the hole wall, further preventing the device from falling off, especially suitable for vertical or large-angle drilling.

[0040] Combination Figure 1 and Figure 2 As shown, the filling body 1 has multiple perforated holes 102 evenly distributed on it. The perforated holes 102 are designed to reduce the weight of the device, while allowing the resin anchoring agent to overflow and directly contact the hole wall, thereby improving the bonding strength. The perforated holes 102 facilitate observation of the installation status of the anchoring agent during construction. In actual use, the later-inserted anchor rod often requires puncturing the vertical anchoring agent packet and breaking up the anti-detachment device. The perforated holes 102 facilitate the anchor rod breaking up the filling body 1.

[0041] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the protrusion 101 is set as a smooth arc surface. The smooth arc surface at the top of the protrusion 101 can evenly distribute the pressure of the protrusion 101 on the vertical anchoring agent pack, ensuring that the protrusion 101 can be embedded inside the pack while effectively preventing the protrusion 101 from puncturing the resin anchoring agent pack, thereby preventing the anchoring agent from leaking.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, the filling body 1 includes a left half cylinder 103 and a right half cylinder 104. Multiple locking mechanisms are provided between the left half cylinder 103 and the right half cylinder 104. The locking mechanisms are evenly arranged along the axial direction of the filling body 1. When the locking mechanisms are locked, the left half cylinder 103 and the right half cylinder 104 are relatively fixed.

[0043] The protrusion 101 increases the friction between the filling body 1 and the anchoring agent pack, but it also increases the difficulty of inserting the resin anchoring agent pack into the filling body 1. The split filling body 1 facilitates quick installation of the pack, and the locking mechanism ensures that the two parts are tightly fixed. It is particularly suitable for narrow or deep hole construction scenarios and improves the ease of operation.

[0044] Specifically, the locking mechanism includes a first connecting plate 105 and a first locking hole 106, such as Figure 5 As shown, the first connecting plate 105 is disposed on the splicing surface of either the left half cylinder 103 or the right half cylinder 104, and the top of the first connecting plate 105 is provided with a locking block 107 extending along the thickness direction of the first connecting plate 105. The first locking hole 106 is provided on the mating surface of the other half of the left half cylinder 103 and the right half cylinder 104. A locking plate 108 is provided in the first locking hole 106. The top end of the locking plate 108 is fixedly located near the opening of the first locking hole 106. The locking plate 108 is arranged at an angle, and the bottom end of the locking plate 108 blocks the sliding path of the locking block 107. The locking plate 108 can deform under the action of external force and avoid the locking block 107. When the first connecting plate 105 is inserted into the first locking hole 106, the side wall of the first connecting plate 105 abuts against the side wall of the first locking hole 106, and the bottom end of the locking plate 108 abuts against the end of the locking block 107.

[0045] The cooperation between the inclined locking plate 108 and the locking block 107 achieves one-way locking, automatically locking during installation to prevent reverse loosening. It not only has a simple structure but also requires no additional tools, thus improving construction efficiency.

[0046] Of course, in addition to the above structure, the locking mechanism may also include a second connecting plate 109 and a second locking hole 111, such as... Figure 7 and Figure 6 As shown, the second connecting plate 109 is disposed on the mating surface of either the left half-cylinder 103 or the right half-cylinder 104, and the top of the second connecting plate 109 is provided with a piercing tip 110. The second locking hole 111 is disposed on the mating surface of the other half-cylinder 103 or the right half-cylinder 104, and a fixing bladder 112 is provided at the bottom of the second locking hole 111. The fixing bladder 112 is made of soft material and contains quick-drying adhesive 113. When the second connecting plate 109 is inserted into the second locking hole 111, the piercing tip 110 pierces and inserts into the fixing bladder 112, so that the quick-drying adhesive 113 fills the space between the walls of the second connecting plate 109 and the second locking hole 111.

[0047] The piercing tip 110, combined with the quick-drying adhesive 113 and the fixing bladder 112, forms a chemical bond after the piercing tip 110 pierces the fixing bladder 112, enhancing the connection strength of the separate structures. This is particularly suitable for vibration environments, preventing the locking mechanism from loosening due to external forces. Simultaneously, this structure also achieves automatic locking during installation, similar to the structures described above. It is not only simple in structure but also requires no additional tools, improving construction efficiency.

[0048] In this embodiment, the mounting body 2 includes a left half 201 and a right half 202. The left half 201 is integrally formed at one end of the left half cylinder 103, and the right half 202 is integrally formed at one end of the right half cylinder 104. When the left half cylinder 103 and the right half cylinder 104 are fastened together to form the filling body 1, the left half 201 and the right half 202 are fastened together to form the mounting body 2. The mounting body 2 and the filling body 1 adopt an integrated split design to ensure the consistency of the overall structure. After the left and right halves 202 are fastened together, a complete hemisphere is formed, reducing assembly errors.

[0049] To facilitate the fixing of the mounting body 2 and the tail fin 3, a connecting mechanism is provided between the mounting body 2 and the tail fin 3.

[0050] Specifically, the connecting mechanism includes a left connecting cylinder 302, a right connecting cylinder 305, and a connecting rod 308, combined with... Figure 3 , Figure 4 and Figure 8 As shown, the left connecting cylinder 302 is formed on the top of the left half 201. The left connecting cylinder 302 is provided with a left large-diameter semi-groove 303 and a left small-diameter semi-groove 304. The left large-diameter semi-groove 303 and the left small-diameter semi-groove 304 are interconnected, and the left large-diameter semi-groove 303 is located at the end of the left small-diameter semi-groove 304 near the filling body 1. The right connecting cylinder 305 is formed on the top of the right half 202. The right connecting cylinder 305 is provided with a right large-diameter semi-groove 306 and a right small-diameter semi-groove 307. The right large-diameter semi-groove 306 and the right small-diameter semi-groove 307 are interconnected, and the right large-diameter semi-groove 306 is located at the end of the right small-diameter semi-groove 307 near the filling body 1. When the left half 201 and the right half 202 are fastened together to form the mounting body 2, the left connecting cylinder 302 and the right connecting cylinder 305 are fastened together to form the connecting cylinder, the left large-diameter half-groove 303 and the right large-diameter half-groove 306 are fastened together to form the large-diameter hole, and the left small-diameter half-groove 304 and the right small-diameter half-groove 307 are fastened together to form the small-diameter hole. The connecting rod 308 includes a large-diameter section 309 and a small-diameter section 310 that are connected to each other. The top end of the small-diameter section 310 is connected to the tail fin 3, the large-diameter section 309 is inserted into the large-diameter hole, and the small-diameter section 310 is inserted into the small-diameter hole.

[0051] The segmented design of the large-diameter and small-diameter holes limits the displacement of the connecting rod 308, preventing the tail fin 3 from swaying or falling off. The snap-fit ​​connecting sleeve simplifies the assembly process and ensures connection stability.

[0052] Finally, the tail fin 301 has a pointed structure at its tip, with the pointed tip facing outwards. The pointed structure with its tip facing outwards can be embedded in the hole wall to enhance the anchoring effect and further prevent the device from sliding under vibration or gravity.

[0053] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
