Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction equipment, in particular to tunnel anchoring construction equipment. Background Art

[0002] Cables, power lines, signal lines, etc. are laid inside the tunnel. These lines are generally positioned and laid through wire conduits. The wire conduits are fixed to the inside of the tunnel with screws or wire conduit clamps, so various fixing positions are formed on the inner wall of the tunnel. Often, holes are drilled in the fixing positions to install internal threaded rivets and then positioned and fixed with screws.

[0003] Since steel bars are arranged in the tunnel support structure, it is necessary to avoid the steel bars when drilling and anchoring the internal threaded rivet columns. Otherwise, the drilling equipment will be damaged and even the performance of the tunnel support structure will be affected, or the drilling holes will have poor fixing performance.

[0004] In the existing technology, when fixing screws to the inner wall of a tunnel, the method of first detecting, then drilling, and finally grouting anchors is adopted. However, these three steps require the entire equipment to be continuously moved in a small range. If there is a deviation in the displacement, the point position will be inaccurate and it is easy to hit the steel bars. In addition, if different points in the same layer have steel bars and some do not, the machine needs to be constantly changed in position, which is not only cumbersome to operate but also increases the chance of deviation.

[0005] Therefore, there is an urgent need for a tunnel anchoring construction equipment to solve the problems existing in the above-mentioned prior art. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0028] Referring to Figures 1-6 As shown, this embodiment provides a tunnel grouting and anchoring construction device, including two end seats 1. A hollow long shaft 5 is rotatably connected between the two end seats 1. A sleeve 4 is slidably connected to the hollow long shaft 5. A cylinder 6 is fixedly connected to the sleeve 4. The output end of the cylinder 6 is fixedly connected to a box body 7. A driving assembly is installed in the box body 7. The driving assembly is drivingly connected to a cylinder 9. The cylinder 9 is located outside the box body 7. Three protective boxes 10 are circumferentially fixedly connected to the outside of the cylinder 9. A through hole 11 is opened on one side of the protective box 10 away from the cylinder 9. A metal detector, a drill, and a grouting and anchoring machine are respectively installed in the three protective boxes 10. The metal detector, the drill, and the grouting and anchoring machine are respectively installed on hydraulic rods. The hydraulic rods are fixedly installed on the inner bottom surface of the protective box 10. The metal detector, the drill, and the grouting and anchoring machine are respectively adapted to the through hole 11 and extend out of the through hole 11 to contact the inner wall of the tunnel during operation. A traction device is connected to any one of the end seats 1, and a control mechanism is fixedly connected to the other end seat 1. The control mechanism is used to control the rotation of the hollow long shaft 5 and the sliding of the sleeve 4.

[0029] During use, one of the end seats 1 moves in the tunnel through a traction device. After reaching the target position, the cylinder 6 is activated to drive the box body 7 to move upward. Then, the metal detector is driven by a hydraulic rod to extend out of the through hole 11 to detect whether there are steel bars in the tunnel. When no steel bars are detected, the driving component is activated to drive the cylinder 9 to rotate, aligning another box body 7 with the just-detected position. The drill is driven by a hydraulic rod to extend out of the through hole 11 to drill the tunnel. Then, the driving component is driven again to drive the cylinder 9 to rotate, aligning the last box body 7 with the drilling position. The hydraulic rod drives the grouting anchor machine to extend out of the through hole 11, driving the screw into the drill hole to complete the grouting and anchoring work at one point; at this time, the control mechanism drives the hollow long shaft 5 to rotate, thereby driving the sleeve 4 to rotate. After rotating to the next point, the above operations are repeated. If steel bars are detected, the control mechanism makes the sleeve 4 slide along the hollow long shaft 5 for re-detection until a position without steel bars is found, without the need for the whole to move back and forth, avoiding deviation of the points. The operation of the present invention is simple and convenient. The circumferential grouting and anchoring work in the tunnel can be completed without the need for the whole to move, and it has high accuracy, high speed, saves time, and speeds up the project progress.

[0030] In a further optimized solution, the control mechanism includes a telescopic component fixedly connected to the inner wall of the end seat 1. The telescopic component is drivingly connected to a rotating component. The telescopic component is detachably connected to a connecting component. The rotating component is fixedly connected to the hollow long shaft 5, and the connecting component is drivingly connected to the sleeve 4. The telescopic component is used to control the rotating component and the connecting component respectively, saving costs and reducing energy consumption.

[0031] In a further optimized solution, the telescopic component includes a first electric telescopic rod 17 fixedly connected to the inner wall of the end seat 1. The output end of the first electric telescopic rod 17 is fixedly connected to a second motor 32. The output end of the second motor 32 is fixedly connected to a second straight gear 16. The second straight gear 16 is drivingly connected to the rotating component, and the second straight gear 16 is detachably connected to the connecting component. The first electric telescopic rod 17 drives the second motor 32 to extend, thereby driving the second straight gear 16 to move upward. The second motor 32 drives the second straight gear 16 to rotate, thereby transmitting power to the connecting component; when the first electric telescopic rod 17 is in the original position, it contacts the rotating component and thereby transmits power to the rotating component.

[0032] In a further optimized solution, the rotating component includes a first straight gear 15 meshing with the second straight gear 16. The first straight gear 15 is fixedly connected to a worm 14. Both ends of the worm 14 are respectively rotatably connected to a bracket 13. The bracket 13 is fixedly connected to the inner wall of the end seat 1. The worm 14 meshes with a worm gear 12. The worm gear 12 is fixedly connected to the outside of the hollow long shaft 5. The second motor 32 drives the second straight gear 16 to rotate. The second straight gear 16 drives the first straight gear 15 to rotate. The first straight gear 15 drives the worm 14 to rotate. The worm 14 drives the worm gear 12 to rotate. The worm gear 12 drives the hollow long shaft 5 to rotate, thereby driving the sleeve 4 to rotate and thus moving to the next point.

[0033] For a further optimized solution, the connecting component includes a third spur gear 19 detachably connected to the second spur gear 16. A vertical shaft 18 is fixedly connected to the center of the third spur gear 19. A first bevel gear 20 is fixedly connected to the top of the vertical shaft 18. The first bevel gear 20 meshes with a second bevel gear 22. A lead screw 21 is fixedly connected to the center of the second bevel gear 22. The lead screw 21 extends into the hollow long shaft 5 and is rotatably connected to the hollow long shaft 5. After the first electric telescopic rod 17 extends, the second spur gear 16 meshes with the third spur gear 19. The second motor 32 is started. The third spur gear 19 drives the vertical shaft 18 to rotate. The vertical shaft 18 drives the first bevel gear 20 to rotate. The first bevel gear 20 drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the lead screw 21 to rotate, thereby causing the sleeve 4 to slide, facilitating the adjustment of the position.

[0034] For a further optimized solution, a limiting groove 23 is provided on the hollow long shaft 5. A slider 24 is slidably connected in the limiting groove 23. The slider 24 is fixedly connected to the sleeve 4. The lead screw 21 passes through the slider 24 and is threadedly connected to the slider 24. When the lead screw 21 rotates, the slider 24 slides in the limiting groove 23. The slider 24 drives the sleeve 4 to move, thereby completing the adjustment of the position.

[0035] For a further optimized solution, the driving component includes a first motor 28 fixedly connected to the inner wall of the box body 7. A connecting shaft 29 is fixedly connected to the output shaft of the first motor 28. The connecting shaft 29 extends outside the box body 7 and is fixedly connected to the cylinder 9. The first motor 28 drives the connecting shaft 29 to rotate. The connecting shaft 29 drives the cylinder 9 to rotate, thereby completing the work of detection, drilling, and grouting and anchoring.

[0036] For a further optimized solution, three connecting plates 27 are circumferentially and fixedly connected to the outer side of the connecting shaft 29. A first induction sheet 30 is fixedly connected to the connecting plate 27. A second electric telescopic rod 25 is fixedly connected to the inner wall of the box body 7. A square plate 26 is fixedly connected to the output end of the second electric telescopic rod 25. A second induction sheet 31 is fixedly connected to the square plate 26. The first induction sheet 30 is in intermittent contact with the second induction sheet 31. When the first induction sheet 30 contacts the second induction sheet 31, the metal detector extends for detection work. After determining that there is no steel bar, the second electric telescopic rod 25 contracts. The first motor 28 rotates. When the connecting plate 27 rotates past the square plate 26, the second electric telescopic rod 25 extends again. Until the next connecting plate 27 contacts the square plate 26, the first motor 28 stops rotating. The drill extends through the through hole 11 for drilling work, and then the above steps are repeated until the grouting and anchoring work is completed. The setting of the three connecting plates 27 can ensure that the rotation angle is the same each time, thereby ensuring that the through holes 11 of each box body 7 are aligned with the points, ensuring the accuracy of grouting and anchoring, and improving work efficiency.

[0037] For a further optimized solution, a distance measuring instrument 8 is fixedly connected to the top surface of the box body 7. The setting of the distance measuring instrument 8 facilitates keeping track of the distance between the box body 7 and the tunnel inner wall at any time and facilitates adjustment.

[0038] For a further optimized solution, a number of support rods 2 are circumferentially and fixedly connected to the outer side wall of the end seat 1. One end of the support rod 2 far from the end seat 1 is rotatably connected to a pulley 3, and the pulley 3 is in contact with the inner wall of the tunnel. The arrangement of the support rods 2 and the pulleys 3 improves the moving performance of the equipment in the tunnel.
