Description

Technical Field

[0001] This utility model belongs to the field of anchor bolt support technology, specifically relating to a combined anchor bolt and anchor cable support device. Background Technology

[0002] In the construction and maintenance of underground engineering projects (such as tunnel excavation, mining, and slope reinforcement), support devices play a crucial role in ensuring the safety and stability of the project. Current support methods primarily rely on anchor bolts or anchor cables. Anchor bolts, typically made of steel bars, penetrate deep into the surrounding rock, providing anchoring through adhesion to the rock. They are effective at reinforcing shallow rock formations but struggle to provide effective restraint for deep rock. Anchor cables, on the other hand, utilize high-strength steel strands inserted into deep, stable rock strata, suspending and anchoring the surrounding rock through prestressing. While they provide significant support force, their effectiveness in locally reinforcing shallow rock is less than ideal. Therefore, some patent documents combine anchor bolts and anchor cables.

[0003] For example, patent application CN202222730303.1 discloses an anchor bolt and anchor cable assembly capable of applying high prestress. This patent achieves the effect of simultaneously applying prestress to both the anchor bolt and the anchor cable by inserting the anchor cable into the anchor bolt. However, because the two ends of the anchor cable are rigidly fixed by a rotating rod and an anchor in this patent, the anchor cable can only rotate passively and cannot adjust the elongation, making it difficult to adapt to varying tensioning requirements in use. Utility Model Content

[0004] In order to solve the technical problem in the prior art that the existing anchor bolt and anchor cable are combined and the two ends of the anchor cable are rigidly fixed by the rotating rod and the anchor, which causes the anchor cable to only be able to rotate passively and cannot adjust the elongation, making it difficult to adapt to the changing tension requirements during use, this utility model provides a combined anchor bolt and anchor cable support device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined anchor bolt and cable support device includes: an anchor bolt body, an anchor cable, and a telescopic adjustment assembly;

[0007] The anchor bolt body has a cavity, and the anchor bolt body has a first port and a second port that are opposite to each other, and the first port and the second port are both connected to the cavity.

[0008] The telescopic adjustment component is disposed on the first port, and part of the telescopic adjustment component extends into the cavity and part of it is outside the first port;

[0009] One end of the anchor cable is disposed in the cavity and fixedly connected to the telescopic adjustment assembly, and the other end extends out of the second port;

[0010] The telescopic adjustment assembly is used to telescopically adjust the length of the anchor cable outside the second port.

[0011] Optionally, the telescopic adjustment assembly includes:

[0015] Optionally, a guide block is provided in the cavity, and the guide block abuts against the threaded sleeve.

[0016] Optionally, the seal includes a grout stop plug and an anchor plate;

[0017] The grout stopper is disposed on the first port;

[0018] The anchor plate is fixedly installed on the side of the grout stop plug away from the first port;

[0019] The adjusting screw extends through the grout stop plug and the anchor plate into the cavity.

[0020] Optionally, a plurality of anchor plate structures are provided on the outer wall of the anchor bolt body, and the plurality of anchor plate structures are disposed near the second port.

[0021] Optionally, the anchor plate structure includes a receiving groove and a plate body;

[0022] The receiving groove is disposed on the outer wall of the anchor bolt body and is located near the second port;

[0023] One end of the plate near the second port is movably connected within the receiving groove;

[0024] When the plate is attached to the receiving groove, the plate is completely contained within the receiving groove.

[0025] Optionally, the plate is provided with an adsorption member, which is located near the end of the plate away from the second port and on the side of the plate closer to the receiving groove.

[0026] When the plate is fully contained within the receiving groove, the adsorption element adsorbs the inner wall of the receiving groove.

[0027] Optionally, the adsorption element is a magnetic adsorption element or a vacuum adsorption element.

[0028] Optionally, a lever is provided on one end of the plate away from the second port.

[0029] Optionally, the plate body and the receiving groove are connected by a damping structure.

[0030] The beneficial effects of this utility model are:

[0031] This invention provides a combined anchor bolt and cable support device. Utilizing the hollow structure inside the anchor bolt body and the through-type design of the first and second ports, the telescopic adjustment component can directly control the extension length of the anchor cable outside the second port. This design overcomes the shortcomings of existing technologies where the anchor cable is rigidly fixed at both ends, resulting in an unadjustable length. When the surrounding rock deforms, the application scenario changes, or secondary tensioning is required, operators can adjust the length of the working section of the anchor cable in real time through the telescopic adjustment component, significantly improving the adaptability of the support system to complex geological conditions. The linkage mechanism between the telescopic adjustment component and the anchor cable ensures a stable and reliable adjustment process, avoiding the risk of steel strand torsion deformation caused by traditional rotational tensioning methods, while also reducing secondary damage to the surrounding rock caused by repeated drilling. This invention can significantly simplify the construction process, achieving single-hole anchoring in confined spaces such as narrow tunnels, shortening support operation time and reducing labor costs, and solving the technical problem that existing technologies cannot dynamically expand and contract the anchor cable according to project requirements.

[0048] See Figure 1The diagram shows a schematic of a combined anchor bolt and cable support device provided in the utility model. The combined anchor bolt and cable support device includes: an anchor bolt body 1, an anchor cable 2, and a telescopic adjustment component 3; the anchor bolt body 1 has a cavity 11, and the anchor bolt body 1 has a first port 12 and a second port 13 that are opposite to each other, both of which are connected to the cavity 11; the telescopic adjustment component 3 is disposed on the first port 12, with part of the telescopic adjustment component 3 extending into the cavity 11 and part of it outside the first port 12; one end of the anchor cable 2 is disposed in the cavity 11 and is fixedly connected to the telescopic adjustment component 3, and the other end extends out of the second port 13; the telescopic adjustment component 3 is used to telescopically drive the anchor cable 2 to adjust its length outside the second port 13.

[0049] In this embodiment, by utilizing the cavity 11 structure inside the anchor body 1 and the through design of the first port 12 and the second port 13, the telescopic adjustment component 3 can directly control the extension length of the anchor cable 2 outside the second port 13. This design overcomes the defect in the prior art where the anchor cable 2 is rigidly fixed at both ends, resulting in the anchor cable 2's length being unadjustable. When the surrounding rock deforms, the usage scenario changes, or secondary tensioning is required, the operator can adjust the working section length of the anchor cable 2 in real time through the telescopic adjustment component 3, significantly improving the support system's adaptability to complex geological conditions. The linkage mechanism between the telescopic adjustment component 3 and the anchor cable 2 ensures a stable and reliable adjustment process, avoiding the risk of steel strand torsion deformation caused by traditional rotational tensioning methods, while also reducing secondary damage to the surrounding rock caused by repeated drilling. This utility model can greatly simplify the construction process, achieving single-hole anchoring in confined spaces such as narrow tunnels, shortening support operation time and reducing labor costs, and solving the technical problem in the prior art where the anchor cable 2 cannot dynamically expand and contract according to project needs.

[0050] Optionally, refer to Figure 2 and Figure 3 The telescopic adjustment assembly 3 of this utility model includes: a sealing element 31, which is fixedly disposed on the first port 12; an adjusting screw 32, which is partially disposed outside the sealing element 31 and extends through the sealing element 31 into the cavity 11, and is movably connected to the sealing element 31; and a threaded sleeve 33, which is movably disposed in the cavity 11, with one end sleeved on the adjusting screw and the other end fixedly connected to the anchor cable 2.

[0051] In this embodiment, the sealing element 31 effectively isolates external rock debris and groundwater from entering, ensuring the long-term reliability of the internal mechanical structure; the exposed part of the adjusting screw 32 is easy for operators to operate, and its rotational force is converted into axial displacement through the threaded sleeve 33, driving the anchor cable 2 to extend and retract linearly. This can not only adjust the length of the anchor cable 2 extending to the second port 13, but also eliminate the stress concentration phenomenon caused by the rotational tensioning of the traditional anchor cable 2; the threaded sleeve 33, as a force transmission hub, disperses the point contact torque into surface contact thrust, reducing the risk of local wear and extending the life of the device.

[0052] Furthermore, a grip cap is provided on the end of the adjusting screw 32 away from the cavity 11 to facilitate the rotation adjustment of the adjusting screw 32.

[0053] Optionally, refer to Figure 3 and Figure 4 In this utility model, a guide block 14 is provided in the cavity 11, and the guide block 14 abuts against the threaded sleeve 33.

[0054] In this embodiment, the abutment design between the guide block 14 and the threaded sleeve 33 forms an axial displacement constraint, eliminating the risk of radial displacement of the threaded sleeve 33 during the stress process. The guide block 14, as a fixed guiding element in the cavity 11, forms a sliding pair with the threaded sleeve 33, ensuring that the threaded sleeve 33 only translates along the predetermined axis when the adjusting screw 32 rotates, avoiding thread engagement failure or bending deformation of the anchor cable 2 due to skew. The guide block 14 maintains transmission stability under high-pressure grouting or surrounding rock extrusion conditions, ensuring the straightness of the anchor cable 2's extension and contraction trajectory, thereby improving the accuracy of prestress application. At the same time, the guide block 14 disperses the frictional load between the threaded sleeve 33 and the inner wall of the cavity 11, reducing metal fatigue damage. It is particularly suitable for the long-term support needs of deep high-stress roadways, significantly reducing maintenance frequency and cost.

[0055] Optionally, refer to Figure 3 The sealing element 31 in this utility model includes a grout stop plug 311 and an anchor plate 312; the grout stop plug 311 is disposed on the first port 12; the anchor plate 312 is fixedly disposed on the side of the grout stop plug 311 away from the first port 12; the adjusting screw 32 extends into the cavity 11 through the grout stop plug 311 and the anchor plate 312.

[0056] In this embodiment, the grout stop plug 311 directly adheres to the first port 12 to form the first sealing barrier, preventing grout overflow and groundwater infiltration. The anchor plate 312 covers the outside of the grout stop plug 311, uniformly transmitting the pressure of the surrounding rock surface to the grout stop plug 311, avoiding local compression deformation that could lead to sealing failure. The design of the adjusting screw 32, which passes through both, maintains rotational freedom, while the rigid support of the anchor plate 312 counteracts the axial reaction force, ensuring that the grout stop plug 311 remains under pressure and maintains a sealed state. This structure can effectively prevent grout leakage during high-pressure grouting construction, improve the density of the anchoring agent filling, and reduce micro-gap seepage caused by the vibration of the adjusting screw 32, providing a dry and stable internal environment for the support system.

[0057] Furthermore, in this embodiment, the grout stopper 311 is made of natural rubber, and the anchor plate 312 adheres to the surface of the surrounding rock during use.

[0058] Furthermore, refer to Figure 5 The anchor cable 2 in this utility model includes a main steel strand 21 and a secondary steel strand 22. The main steel strand 21 is located at the center of the anchor cable 2, and the secondary steel strand 22 is spirally wound around the outside of the main steel strand 21. The main steel strand 21 is centrally located, and the secondary steel strand 22 is tightly attached to it in a spiral winding manner to form a "rope strand" reinforcement structure, so that the main steel strand 21 and the secondary steel strand 22 deform together under stress, and significantly improve the overall torsional resistance through mutual support.

[0059] Furthermore, both the main steel strand 21 and the auxiliary steel strand 22 are provided with a galvanized layer on their outer side. The galvanized layer is formed by hot-dip galvanizing process to form a dense zinc layer, which builds an electrochemical protective barrier on the surface of the steel strand. The outer side of the anchor cable 2 is provided with a sleeve 23. The sleeve 23 is made of high-density polyethylene material, which has excellent waterproofness and chemical stability, and prevents the sleeve 23 from deforming under pressure.

[0060] Furthermore, the space between the sleeve 23 and the main steel strand 21 and the auxiliary steel strand 22 is uniformly filled with anti-corrosion grease 24, thereby maintaining good lubrication and sealing, forming a physical isolation layer to isolate groundwater and acid and alkali media from corrosion.

[0061] Optionally, refer to Figure 6 In this utility model, the outer wall of the anchor rod body 1 is provided with multiple anchor plate structures 4, which are located near the second port 13.

[0062] In this embodiment, multiple anchor plate structures 4 are provided on the outer wall of the anchor bolt body 1 to increase the mechanical engagement area between the device and the inner wall of the hole. The anchor plate structures 4 are arranged near the second port 13 to form a multi-point anchoring network around the extension of the anchor cable 2, which enhances the local constraint force of the shallow surrounding rock. Compared with traditional smooth anchor bolts, this design improves the pull-out bearing capacity by disturbing the stress field of the soil and rock through discretely distributed anchor plate structures 4. In soft rock or fractured zones, the anchor plate structures 4 can also be embedded in the rock mass to suppress radial deformation and reduce the risk of support failure.

[0063] Optionally, refer to Figure 7 and Figure 8 The anchor plate structure 4 in this utility model includes a receiving groove 41 and a plate body 42; the receiving groove 41 is disposed on the outer wall of the anchor rod body 1 and is located near the second port 13; one end of the plate body 42 near the second port 13 is movably connected to the receiving groove 41; when the plate body 42 is in contact with the receiving groove 41, the plate body 42 is completely contained in the receiving groove 41.

[0064] In this embodiment, the retractable nature of the anchor plate structure is achieved through the movable connection design between the receiving groove 41 and the plate 42. When the plate 42 is retracted, it is completely embedded in the receiving groove 41, significantly reducing the external outline dimensions of the anchor body 1 and lowering the difficulty of transportation and installation over obstacles. When unfolded, the plate 42 detaches from the receiving groove 41 to form a cantilever support, providing immediate anchoring resistance and improving construction convenience. The receiving groove's enclosure and protection of the plate 42 prevents damage from transportation collisions, making it suitable for long-distance mine transportation scenarios and ensuring the integrity of the support device.

[0065] Optionally, refer to Figure 7 and Figure 8 In this utility model, the plate 42 is provided with an adsorption member 421. The adsorption member 421 is close to the end of the plate 42 away from the second port 13 and is located on the side of the plate 42 close to the receiving groove 41. When the plate 42 is completely contained in the receiving groove 41, the adsorption member 421 adsorbs the inner wall of the receiving groove 41.

[0066] In this embodiment, the adsorption and fixing design of the adsorption member 421 and the inner wall of the receiving groove 41 provides a reliable holding force for the plate 42 in its stored state. The adsorption member 421 maintains the plate 42 in a stable stored state under vibration and tilting conditions, eliminating the safety hazards caused by accidental unfolding during underground transportation.

[0067] Optionally, the adsorption element 421 in this utility model is a magnetic adsorption element or a vacuum adsorption element.

[0068] In this embodiment, the magnetic adsorption component uses a permanent magnet or electromagnetic field to generate adsorption force, which is suitable for ferrous surrounding rock environments; the vacuum adsorption component uses negative pressure adsorption and is suitable for non-magnetic rock strata. Both provide a tool-free fixation / release experience.

[0069] Optionally, refer to Figure 8 In this utility model, a lever 422 is provided on the end of the plate 42 that is away from the second port 13.

[0070] In this embodiment, the lever 422 serves as a manual operating gripper for the plate 42, providing safe and efficient unfolding control. During use, the operator applies leverage force through the lever 422 to pry the plate 42, overcoming the adsorption force and damping torque of the adsorption component 421, thereby achieving precise and controllable unfolding action and improving usage efficiency.

[0071] Optionally, the plate 42 and the receiving groove 41 in this utility model have a damping structure at the movable connection.

[0072] In this embodiment, damping structures such as damping shafts provide motion resistance for the unfolding process of the plate 421, eliminate inertial impact, and prevent personnel injury, rock wall scratches, or structural deformation caused by the instantaneous popping of the plate 42; during storage, it helps the plate 42 to return to its original position smoothly, reducing the intensity of manual operation.
