Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to a locking foot anchor rod guide device. Background Art

[0002] In the complex environment of tunnel construction, especially when employing the arch-first, wall-later excavation method, locking anchors play a crucial role as a key structure for ensuring construction safety. Driven vertically into the rock face at the arch foot, they prevent the arch crown from shrinking and collapsing, effectively supporting the entire primary support system for the upper steps. This technology is particularly common in tunnel construction with rock mass above Grade 4, where steel arch anchor shotcrete is often used as the primary support material.

[0003] In practice, after the steel arch is installed, construction workers must quickly install locking anchors to stabilize the structure. However, this process presents a significant problem: due to complex and variable geological conditions and varying levels of skill among construction workers, the precise angle of the locking anchors is often difficult to control, resulting in inconsistent anchoring quality. This not only affects the overall stability of the tunnel but also poses potential safety risks.

[0004] Prior art often uses locking anchor guides to assist with positioning. However, these guides are often temporary and lack the necessary adjustment capabilities. Specifically, their angles and heights are often fixed, making them difficult to adjust based on project conditions, increasing construction costs. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0021] The embodiment of the present application provides a locking foot anchor rod guide device, such as Figures 1 to 2 As shown. The locking foot anchor rod guide device includes a platform 1, multiple lifting columns 2, multiple support assemblies 3, multiple rotating parts 4, multiple locking parts 5 and multiple guide cylinders 6. Multiple lifting columns 2 are arranged circumferentially on the bottom of the platform 1, and the multiple lifting columns 2 are configured to adjust the height of the platform 1. Multiple support assemblies 3 are arranged at intervals along the length direction of the platform 1, and are each provided with a first connecting hole 321 and a rotating groove 322 along the height direction. Multiple rotating parts 4 are connected to the corresponding first connecting holes 321 through corresponding rotating shafts, and are provided with second connecting holes corresponding to the corresponding rotating grooves 322. Multiple guide cylinders 6 are detachably connected to one end of the rotating part 4 away from the corresponding support assembly 3. One end of the multiple locking parts 5 passes through the corresponding second connecting hole and the rotating groove 322, and is configured to lock the corresponding rotating part 4 and the support assembly 3 after the rotating part 4 is adjusted to a preset angle.

[0022] Specifically, in the locking foot anchor guide device of the present application, four lifting struts 2 can be provided to ensure the stability and adjustable flexibility of the platform 1. Furthermore, to accommodate the simultaneous construction of multiple locking foot anchors, two each of the rotating member 4, guide cylinder 6, and support assembly 3 can be provided, effectively improving construction efficiency. The rotation slot 322 of the present embodiment aligns with the motion trajectory of the rotating member 4.

[0023] It should be noted that in the locking foot anchor guide device of the present embodiment, the lifting strut 2 can flexibly adjust the height of the platform 1 to accommodate varying working environments and ground conditions. Multiple support assemblies 3 are spaced apart along the length of the platform 1, each equipped with a first connection hole 321 and a rotation slot 322. The rotating member 4 is connected to the first connection hole 321 via a rotating shaft and has a second connection hole corresponding to the rotation slot 322. To adjust the angle of the guide cylinder 6, simply rotate the rotating member 4 within the rotation slot 322 to a predetermined angle. This ensures the stability of the guide cylinder 6 after adjustment, avoids construction errors, and improves construction accuracy. After the rotating member 4 is adjusted to the desired angle, the locking member 5 is inserted through the second connection hole and the rotation slot 322 to securely lock the rotating member 4 to the support assembly 3, ensuring that the guide cylinder 6 is not affected by external forces during operation. Furthermore, the guide cylinder 6 and the rotating member 4 are detachably connected, facilitating replacement of guide cylinders 6 of different specifications or wear, enhancing the device's flexibility and durability. By adjusting the height of the platform 1 and rotating the angle of the guide cylinder 6, the locking foot anchor guide device provided by this application can quickly adapt to various working environments and anchor construction requirements, improving work efficiency. At the same time, its stable structure and simple operation reduce the complexity and danger of manual operation and enhance safety during the construction process.

[0024] In this embodiment of the present application, the locking foot anchor rod guide device further includes a plurality of clamping members 8. The plurality of clamping members 8 are respectively disposed at one end of the corresponding rotating member 4 away from the corresponding support assembly 3. The plurality of guide cylinders 6 are each disposed within the corresponding clamping members 8, and the clamping members 8 are configured to clamp the corresponding guide cylinders 6.

[0025] It should be noted that the present application uses the clamping member 8 to ensure that the guide cylinder 6 will not easily become loose or displaced due to external factors after the angle is adjusted, thereby ensuring the accuracy and safety of the construction. At the same time, the present application can install guide cylinders 6 of different specifications to adapt to different locking anchor rods, saving costs.

[0026] Specifically, the clamping member 8 is a clamp.

[0027] In this embodiment of the present application, the support assembly 3 includes a support platform 31 and a connector 32. The support platform 31 is disposed on the side of the platform 1 away from the lifting support 2. The connector 32 is disposed on the side of the support platform 31 away from the platform 1 and has a first connecting hole 321 and a rotation slot 322 disposed along its height.

[0028] It should be noted that support platform 31, serving as a transitional structure between connector 32 and platform 1, effectively distributes and bears the loads from rotating member 4 and guide cylinder 6, significantly enhancing the structural stability of the entire device. Connector 32 is typically carefully crafted from high-strength materials to ensure it maintains its shape and integrity under heavy loads, preventing deformation or breakage.

[0029] In the embodiment of the present application, the support platform 31 and the connecting member 32 form an L-shaped structure.

[0030] In the embodiment of the present application, the locking foot anchor rod guide device further comprises a plurality of elastic layers, which are respectively arranged on the inner walls of the corresponding guide cylinders 6 .

[0031] It should be noted that the elastic layer can not only reduce the construction errors caused by the unevenness or wear of the inner wall of the guide tube 6, thereby improving the construction accuracy and ensuring that the insertion angle and depth of the locking foot anchor rod meet the design requirements; it can also reduce friction and impact force, making the locking foot anchor rod easier to insert into the guide tube 6, thereby improving construction efficiency and shortening construction period.

[0032] In the embodiment of the present application, the locking foot anchor rod guide device further includes a plurality of bases 7. The plurality of bases 7 are respectively arranged at the end of the corresponding lifting pillar 2 away from the platform 1.

[0033] Specifically, the base 7 is firmly connected to the foundation by bolts. This connection method enables the locking foot anchor rod guide device to better resist interference from external factors such as lateral wind force and vibration, and effectively avoid overturning or instability.

[0034] In this embodiment of the present application, the lifting support 2 assembly includes a first column 21, a second column 22, and an electric cylinder 23. The first column 21 is sleeved onto the outer wall of the second column 22, with its end distal to the second column 22 connected to the platform 1. The electric cylinder 23 is disposed within both the second column 22 and the first column 21. The first column 21 is connected to the output shaft of the electric cylinder 23. The electric cylinder 23 is configured to move the first column 21 upward and downward, thereby moving the platform 1 upward and downward.

[0035] It should be noted that the electric cylinder 23 , as a power source, can accurately control the lifting movement of the first column 21 .

[0036] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0037] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
