At the same time, the anchor rod installation cannot ensure uniform distribution of the anchor rods, which may increase the risk of deformation or damage of the tunnel structure due to uneven stress. In addition, the tunnel generally has an arc-shaped top surface, but there are few anchor rod installation devices on the market that can adapt to the arc-shaped top surface. Utility Model Content

The rotating wheel is driven to rotate by the rotation of the rotating shaft, so that the insert is inserted into the annular slot evenly arranged under the elastic force of the spring. Then the telescopic end of the second telescopic mechanism is inserted into the corresponding socket to limit the rotating wheel to prevent installation misalignment. The same angle can be rotated each time, so that the anchor is evenly installed, and the load is evenly distributed, which effectively enhances the structural stability and resistance of the tunnel, reduces local stress concentration, and reduces the risk of deformation or damage of the tunnel structure due to uneven stress.

The positioning assembly 6 and the telescopic mechanism 7 can be driven to rotate along the arc top surface of the tunnel, so that the drilling angle of the anchor installation is as perpendicular to the arc top surface as possible.

[0024] Further explanation, the angle adjustment component 4 includes a rotating wheel 41 coaxially connected to the rotating shaft 36; a plurality of slots 42 are evenly opened in an annular shape on the rotating wheel 41, and a second fixing plate 43 connected to the machine base 1 is provided on one side; a sleeve 44 is connected to the side of the second fixing plate 43 facing the rotating wheel 41; a plug 45 is slidably connected in the sleeve 44; the end of the plug 45 facing the rotating wheel 41 is engaged with the slot 42, and the upper and lower ends are respectively provided with adjustment inclined surfaces, and a spring 46 is also connected between the plug 45 and the second fixing plate 43. When the positioning component 6 and the telescopic mechanism 7 rotate with the rotating component 3, they rotate at the same angle each time, so that the anchor rods are evenly installed, and then the load is evenly distributed, which effectively enhances the structural stability and resistance of the tunnel, reduces local stress concentration, and reduces the risk of deformation or damage of the tunnel structure due to uneven stress. At the same time, it reduces the maintenance and repair costs and improves the economic benefits of the project.

[0025] Further explanation, a plurality of sockets 48 corresponding to the slots 42 are evenly arranged in a ring on the rotating wheel 41; a telescopic mechanism 2 47 is provided on the side of the fixed plate 1 37 facing the rotating wheel 41, and the telescopic mechanism 2 47 is an electric telescopic rod; the telescopic end of the telescopic mechanism 2 47 is engaged with the socket 48.

[0026] Embodiment 2

[0027] like Figure 4 As shown, the tunnel anchor bolt installation device proposed by the present invention, compared with the first embodiment, this embodiment further includes: the positioning assembly 6 is symmetrically arranged about the telescopic mechanism 7. It can provide more stable positioning for the anchor bolt installation and prevent the anchor bolt installation from being misplaced.

[0028] Further explanation, the positioning assembly 6 includes a fixed cylinder 61 arranged at the upper end of the base 5; a slide groove 62 is provided at the upper end of the fixed cylinder 61; a sliding cylinder 63 is slidably connected to the slide groove 62; a suction cup 66 is connected to the upper end of the sliding cylinder 63; a threaded rod 64 is also rotatably connected in the fixed cylinder 61; the lower end of the sliding cylinder 63 is threadedly connected to the threaded rod 64; a driving mechanism 65 is provided at the lower end of the threaded rod 64, and the driving mechanism 65 is a motor. The threaded rod 64 rotates to drive the sliding cylinder 63 to extend and retract, and the suction cup 66 is adsorbed on the tunnel surface, so as to position the anchor bolt installation, and prevent the movement of equipment during the anchor bolt installation from causing the anchor bolt installation to be misplaced, thereby affecting the construction progress or engineering quality.

[0029] Further explanation, a connecting rod 67 is commonly connected between the sliding cylinders 63 on both sides; a placement cylinder 68 for placing the anchor rod is provided in the middle of the connecting rod 67. The anchor rod plays a role of positioning and limiting, and the anchor rod can be inserted from the placement cylinder 68, and one end of the anchor rod is abutted against the telescopic end of the telescopic mechanism 7, so that the telescopic end of the telescopic mechanism 7 is extended to push the anchor rod into the inner wall of the tunnel to complete the installation.

[0030] The working principle of the utility model is as follows: when working, first insert the anchor rod from the placement tube 68, and make one end of the anchor rod abut against the telescopic end of the telescopic mechanism 7. Then start the driving mechanism 1 33 to drive the threaded rod 1 32 to rotate, thereby driving the rack 34 to move, and then drive the gear 35, the rotating shaft 36, the base 5, the positioning assembly 6 and the telescopic mechanism 7 to rotate, and make the positioning assembly 6 and the telescopic mechanism 7 rotate to the position where the anchor rod needs to be installed. Then start the driving mechanism 2 65 to drive the threaded rod 2 64 to rotate, thereby driving the sliding tube 63 to extend, and finally make the suction cup 66 adsorbed on the inner wall of the tunnel to position the anchor rod installation. Then start the telescopic mechanism 7, so that the telescopic end of the telescopic mechanism 7 extends to insert the anchor rod into the tunnel, and complete the installation of an anchor rod. Then, the driving mechanism 1 33 is started again, and the rotation of the rotating shaft 36 drives the rotating wheel 41 to rotate, so that the adjustment inclined surface on the inserting strip 45 abuts against the groove wall of the slot 42 and retracts into the sleeve 44. Then, as the rotating wheel 41 rotates, the inserting strip 45 is inserted into the next slot 42 under the elastic force of the spring 46. Then, the telescopic mechanism 2 47 is started, and the telescopic end of the telescopic mechanism 2 47 is inserted into the corresponding insertion hole 48, and the rotating wheel 41 is limited, so as to prevent the positioning assembly 6 and the telescopic mechanism 7 from rotating during installation and causing installation misalignment. Then, the next anchor rod is installed again, and the above process is repeated.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
