Technical Field

[0001] This utility model relates to the field of anchor bolt support technology, and in particular to an anchor bolt support device for municipal tunnel engineering. Background Technology

[0002] In municipal tunnel engineering, bolt support is a crucial element in ensuring the stability and safety of the tunnel structure. However, traditional bolt support methods have some significant limitations and challenges:

[0003] Traditional anchor bolt support typically relies on simple mechanical connections or welding to fix the support sleeve to the anchor bolt. This method is prone to insecure fixation, especially in complex or variable geological conditions, where the anchor bolt may shift or loosen. Secondly, traditional support systems usually only provide support in one direction and lack the ability to provide all-round protection for the anchor bolt, especially when multi-directional support is required.

[0004] To overcome the aforementioned problems and meet the needs of municipal tunnel engineering for efficiency, safety, and convenience, an anchor bolt support device for municipal tunnel engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anchor bolt support device for municipal tunnel engineering, which can avoid the traditional anchor bolt support that usually relies on simple mechanical connection or welding to fix the support sleeve to the anchor bolt. This method is prone to insecure fixation, especially in the case of complex or variable geological conditions, where the anchor bolt may shift or loosen. Secondly, traditional support systems usually only provide support in one direction and lack the ability to protect the anchor bolt in all directions.

[0006] This utility model provides an anchor bolt support device for municipal tunnel engineering, including a support sleeve, which is sleeved on the outside of the anchor bolt, and a fixing sleeve is provided inside the support sleeve. The fixing sleeve is fixed to the anchor bolt by bolts. Multiple sets of sliding grooves are opened on the outside of the support sleeve, and a positioning mechanism is slidably installed in the sliding grooves. At the same time, a support component is inserted into one side of the support sleeve, and the support component supports the end of the anchor bolt.

[0007] Preferably, the positioning mechanism includes a movable block that slides in a groove, a hollow cylinder is fixedly disposed on the lower side of the movable block, and a fixed rod is slidably disposed inside the hollow cylinder.

[0008] Preferably, a second lead screw is rotatably installed inside the hollow cylinder, and the second lead screw is threadedly connected to the fixed rod.

[0009] Preferably, a through groove is provided on one side of the slide, one side of the moving block slides in the through groove, and a lead screw is rotatably provided on one side of the through groove, the lead screw being threadedly connected to the moving block.

[0011] Preferably, a sliding sleeve is slidably provided on the insertion rod, and a side rod is hinged to one side of the sliding sleeve.

[0012] This utility model provides an anchor bolt support device for municipal tunnel engineering, which, compared with the prior art:

[0013] 1. This utility model uses a fixing sleeve to fix the support sleeve to the anchor rod, and then slides the fixing rod out from the hollow cylinder and inserts it into the object around the anchor rod. The fixing rod is used to support the anchor rod and prevent it from shifting or loosening. The insertion position of the fixing rod can be precisely adjusted by the screw rod to ensure that the fixing rod can be accurately inserted into the optimal support point, reducing the risk of displacement caused by geological changes.

[0014] 2. This utility model uses insert blocks to firmly fix the support sleeve to the anchor rod, ensuring a tight connection between the support sleeve and the anchor rod, and improving the stability of the support sleeve on the anchor rod. The insert rod is vertically inserted into the soil, forming vertical support for the anchor rod. The insertion rod penetrates deep into the ground, increasing the overall stability of the anchor rod and allowing it to maintain good fixation even under complex geological conditions. Combined with the insertion of side rods, the support effect of the anchor rod is further reinforced from the side. The design of the side rods can effectively distribute pressure from different directions, improving the deformation resistance of the entire support system. Through the combined use of insert rods and side rods, a multi-point support structure is formed, allowing the anchor rod to obtain stable support in all directions and avoiding damage caused by local stress concentration.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please refer to Figures 1-5 This utility model provides an anchor bolt support device for municipal tunnel engineering, including a support sleeve 1, which is sleeved on the outside of the anchor bolt 17, and a fixing sleeve 2 is provided inside the support sleeve 1. The fixing sleeve 2 is fixed to the anchor bolt 17 by bolts, ensuring that the support sleeve 1 can be stably attached to the anchor bolt 17, providing a solid foundation for subsequent support work.

[0025] Multiple sets of sliding grooves 3 are opened on the outer side of the support sleeve 1. A positioning mechanism is slidably installed in the sliding groove 3. The positioning mechanism includes a movable block 6 that slides in the sliding groove 3. A hollow cylinder 7 is fixedly installed on the lower side of the movable block 6. A fixed rod 8 is slidably installed inside the hollow cylinder 7. After the fixed rod 8 slides out of the hollow cylinder 7, it can be directly inserted into the objects around the anchor rod 17, such as rock strata or soil, so as to effectively support the anchor rod 17 and prevent it from shifting or loosening.

[0026] Inside the hollow cylinder 7, there is a second lead screw 9, which is connected to the fixed rod 8 by a thread. By rotating the second lead screw 9, the fixed rod 8 can be made to slide stably, ensuring that it will not accidentally slide back into the hollow cylinder 7 during the insertion process. This design significantly improves the stability of the fixed rod 8 and prevents the fixed rod 8 from sliding into the hollow cylinder 7 during insertion due to improper operation or external interference, thereby ensuring the reliability and accuracy of the support effect.

[0027] Furthermore, a through groove 4 is provided on one side of the chute 3, and one side of the moving block 6 slides in the through groove 4. A screw rod 5 is rotatably provided on one side of the through groove 4. The screw rod 5 is threadedly connected to the moving block 6. Depending on the support conditions, the screw rod 5 can be rotated to adjust the position of the moving block 6, so that the moving block 6 moves with the hollow cylinder 7, changing the support position of the fixed rod 8. This is suitable for support needs under different geological conditions.

[0028] Meanwhile, a support component is inserted into one side of the support sleeve 1, and the support component supports the end of the anchor rod 17.

[0029] Specifically, the support component includes a plug 13, which is inserted into a hole 16 on one side of the support sleeve 1. A support head 10 is fixedly provided on one side of the plug 13. A support groove 11 is provided on the upper side of the support head 10, and a plug rod 12 is provided on the lower side of the support head 10. The design of the plug 13 ensures a tight connection between the support sleeve 1 and the anchor rod 17, improving the stability of the support sleeve 1 on the anchor rod 17. The support sleeve 1 not only plays a fixing role, but also provides additional structural support, enhancing the stability of the entire system and preventing the support sleeve 1 from sliding or loosening during use. The plug rod 12 is vertically inserted into the soil to form vertical support for the anchor rod 17. This vertical support method can effectively distribute the pressure borne by the anchor rod 17 and reduce the risk of displacement caused by geological changes.

[0030] The insertion rod 12 extends deep into the ground, increasing the overall stability of the anchor rod 17 and enabling it to maintain a good fixed state even under complex geological conditions. A sliding sleeve 14 is slidably installed on the insertion rod 12, and a side rod 15 is hinged to one side of the sliding sleeve 14. Combined with the insertion of the side rod 15, the support effect of the anchor rod 17 is further reinforced from the side. The design of the side rod 15 can effectively distribute the pressure from different directions and improve the deformation resistance of the entire support system.

[0031] The combination of insert rod 12 and side rod 15 forms a multi-point support structure, which enables anchor rod 17 to obtain stable support in all directions and avoid damage caused by local stress concentration.

[0032] In summary, the working principle of the anchor bolt support device for municipal tunnel engineering according to this utility model embodiment is as follows: First, the support sleeve 1 is fitted onto the outside of the anchor bolt 17, and the fixing sleeve 2 is fixed to the anchor bolt 17 by bolts to ensure that the support sleeve 1 can be stably attached to the anchor bolt 17. According to the support situation, the screw rod 5 can be rotated to adjust the position of the moving block 6, so that the moving block 6 moves with the hollow cylinder 7, changing the support position of the fixing rod 8, which is suitable for support needs under different geological conditions. Then, the screw rod 9 can be rotated to achieve stable sliding of the fixing rod 8, so that the fixing rod 8 can be stably inserted into the objects around the anchor bolt 17. Through the combination of the insert block 13, the support head 10 and the insert rod 12, additional vertical support is provided. Combined with the design of the side rod 15, the support effect of the anchor bolt 17 in various directions is further enhanced, forming a multi-point support structure and improving the reliability and safety of the overall support system.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
