[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figure 1 and Figure 3As shown, a tunneling machine is equipped with an anchor arm device, including a mounting bracket 1, a horizontal rotation mechanism 2 is provided at the upper end of the mounting bracket 1, a horizontal telescopic mechanism 3 is provided at the front end of the horizontal rotation mechanism 2, an operating platform 4 is provided at the upper end of the horizontal telescopic mechanism 3, a rotation mechanism 5 is provided at the front end of the operating platform 4, and an anchor bolt installation mechanism 6 is provided at the front end of the rotation mechanism 5.

[0028] The anchor bolt installation mechanism 6 includes a fixed cylinder 601. A first hydraulic cylinder 602 is fixedly installed at the bottom inner side of the fixed cylinder 601. A lifting plate 603 is fixedly connected to the output end of the first hydraulic cylinder 602. The lifting plate 603 is slidably connected inside the fixed cylinder 601. Guide rods 604 are fixedly connected to the four corners of the upper end of the lifting plate 603. A support plate 605 is fixedly connected to the upper end of the guide rods 604. An installation groove 606 is formed through the center of the upper end of the support plate 605. A second hydraulic cylinder 607 is fixedly installed at the center of the upper end of the lifting plate 603. The output end of 7 is fixedly connected to a lifting seat 608, which is slidably connected to the outer surface of the guide rod 604. The lifting seat 608 is provided with a third driving cavity 609. The upper end of the third driving cavity 609 is provided with a storage cavity 6010. The bottom inner side of the third driving cavity 609 is fixedly installed with a third hydraulic cylinder 6011. The output end of the third hydraulic cylinder 6011 is fixedly connected to a push block 6012. The anchor rod body 6013 is inserted into the storage cavity 6010. The diameter of the anchor rod body 6013 is the same as the diameter of the mounting groove 606 and the storage cavity 6010.

[0029] Furthermore, the anchor bolt body 6013 is installed in the storage cavity 6010 by insertion. The bottom end of the anchor bolt body 6013 abuts against the upper end of the push block 6012. When excavating tunnels with soft soil, the anchor bolt body 6013 needs to be driven into the inner wall of the tunnel after the tunnel boring machine advances a certain distance. The anchor bolt body 6013 driven into the inner wall of the tunnel can connect the tunnel excavation face with the deep, hard rock and soil layer, providing additional support, preventing soil instability, and ensuring tunnel stability. When it is necessary to drive the anchor bolt body 6013 in, the lifting plate 603 is moved upward by the first hydraulic cylinder 602. Pushing the support plate 605 outwards, the support plate 605 abuts against the inner wall of the excavated tunnel to provide temporary support. At this time, the second hydraulic cylinder 607 pushes the lifting seat 608 upwards, which can drive the anchor bolt body 6013 through the installation groove 606 and insert it into the wall. Since the support plate 605 and the lifting seat 608 have a certain thickness, it is difficult to insert the anchor bolt body 6013 completely by the second hydraulic cylinder 607 alone. At this time, the third hydraulic cylinder 6011 pushes the pushing block 6012 upwards, which can push out the remaining anchor bolt body 6013, thereby ensuring that the anchor bolt body 6013 is fully inserted.

[0030] Furthermore, the upper end of the support plate 605 is arc-shaped, which allows it to fit better against the rock wall, increasing the contact area with the rock wall and thus providing better support.

[0031] Furthermore, the left and right inner walls of the fixed cylinder 601 are provided with symmetrically distributed guide grooves 6014, and guide blocks 6015 are slidably connected inside the guide grooves 6014. The two guide blocks 6015 are respectively fixedly connected to the left and right sides of the lifting plate 603.

[0032] Furthermore, mounting bracket 1 has pre-drilled mounting screw holes, through which the device can be installed on the tunneling machine using mounting screw holes and fastening bolts.

[0033] Furthermore, the operating platform 4 provides a standing platform for staff to facilitate auxiliary operations.

[0034] Reference Figure 1 and Figure 5 As shown, the rotating mechanism 5 includes a second support base 501, a second drive cavity 502 is provided inside the second support base 501, a third gear 503 is rotatably connected inside the second drive cavity 502, a second drive shaft 504 is fixedly connected to the front end of the third gear 503, the end of the second drive shaft 504 away from the third gear 503 passes through the front end of the second drive cavity 502 and is fixedly connected to a rotating seat 505, a second motor 506 is fixedly installed at the rear end of the second support base 501, the output end of the second motor 506 passes through the rear end of the second support base 501 and is fixedly connected to a fourth gear 507, the fourth gear 507 is rotatably connected inside the second drive cavity 502, the fourth gear 507 meshes with the third gear 503, a fixed cylinder 601 is fixedly connected to the inner side of the rotating seat 505, and the second support base 501 is fixedly connected to the front end of the operating platform 4.

[0035] Furthermore, the second motor 506 drives the fourth gear 507 to rotate, which in turn drives the third gear 503 to rotate. Under the transmission action of the second drive shaft 504, the rotating seat 505 will drive the anchor bolt installation mechanism 6 to rotate synchronously, thereby adjusting the angle of the anchor bolt installation mechanism 6. This allows the anchor bolt installation mechanism 6 to perform anchor bolt body 6013 installation operations in different directions on the same plane, which can improve the flexibility of the anchor bolt body 6013 arrangement and thus enhance the support effect of the anchor bolt body 6013.

[0036] Reference Figure 1 and Figure 2 As shown, the horizontal telescopic mechanism 3 includes a first connecting block 301, a hydraulic rod 302 is fixedly installed at the front end of the first connecting block 301, a second connecting block 303 is fixedly connected to the output end of the hydraulic rod 302, a fixed seat 304 is fixedly connected to the outer surface of the second connecting block 303, and the upper end of the fixed seat 304 is fixedly connected to the lower end of the operating platform 4.

[0037] Furthermore, when the installation of the anchor bolt body 6013 is not required, the hydraulic rod 302 is in a retracted state. At this time, the operating platform 4 and the anchor bolt installation mechanism 6 are also in a retracted state, reducing the space occupied by the tunneling machine and facilitating excavation operations. When the anchor bolt installation mechanism 6 needs to be used, the operating platform 4 and the anchor bolt installation mechanism 6 can be pushed out by the hydraulic rod 302 to move the second connecting block 303 in the horizontal direction, thereby enabling the installation operation of the anchor bolt body 6013. The retractable design helps to improve the flexibility of the tunneling machine in confined working environments.

[0038] Reference Figure 1 and Figure 4 As shown, the horizontal rotation mechanism 2 includes a first support base 201 fixedly connected to the upper end of the mounting bracket 1. The first support base 201 has a first drive cavity 203 inside. A first motor 204 is fixedly installed inside the first drive cavity 203. The output end of the first motor 204 passes through the bottom end of the first drive cavity 203 and is fixedly connected to a first gear 205. Two symmetrically distributed support plates 202 are fixedly connected to the front end of the first support base 201. A first drive shaft 206 is rotatably connected between the two support plates 202. Two limiting sleeves 207 are fixedly connected to the surface of the first drive shaft 206. One end of the first drive shaft 206 passes through the upper end of the lower support plate 202 and is fixedly connected to a second gear 208. The second gear 208 meshes with the first gear 205. A first connecting block 301 is fixedly connected to the outer surface of the first drive shaft 206 and is located between the two first drive shafts 206.

[0039] Furthermore, the first motor 204 drives the first gear 205 to rotate, which in turn drives the second gear 208 to rotate. This, in turn, drives the anchor bolt installation mechanism 6 to rotate horizontally through the transmission action of the first drive shaft 206. In conjunction with the use of the rotating mechanism 5, the anchor bolt body 6013 can be installed at multiple angles.

[0040] Working principle: Before use, the two sets of devices are symmetrically installed on both sides of the tunneling machine through the pre-drilled mounting screw holes and fastening bolts on the mounting bracket 1. When it is necessary to install the anchor bolt body 6013, the anchor bolt installation mechanism 6 is pushed out by the horizontal telescopic mechanism 3. The angle of the anchor bolt installation mechanism 6 is adjusted by the rotating mechanism 5 and the horizontal rotating mechanism 2 as needed. After adjusting to the target position, the lifting plate 603 is raised by the first hydraulic cylinder 602, so that the support plate 605 is pushed outward to contact the inner wall of the tunnel and provide temporary support. Then, the lifting seat 608 is raised by the second hydraulic cylinder 607, pushing the anchor bolt body 6013 through the installation groove 606 and inserting it into the inner wall of the tunnel. Then, the pushing block 6012 is pushed by the third hydraulic cylinder 6011 to push out all the remaining anchor bolt bodies 6013, ensuring that the anchor bolt is completely inserted into the tunnel. By installing the anchor bolt body 6013, the support force of the inner wall of the tunnel can be enhanced, the surrounding rock instability can be prevented, and the safety of the tunnel structure can be ensured.
