[0002] With the accelerated pace of urbanization and the development of multi-dimensional transportation networks, the depth and breadth of underground space development are constantly expanding. Tunnel engineering, as a crucial component of underground space development, is widely used in railways, highways, and urban subways. During tunnel excavation, especially when traversing soft strata, fractured zones, or water-rich areas, advanced small-diameter pipe grouting technology, with its flexible operation and strong adaptability, has become one of the core technologies for ensuring construction safety in order to prevent face collapse and control surface subsidence. However, traditional advanced small-diameter pipe grouting devices still have some shortcomings.

[0032] Example:

[0033] As attached Figure 1 To be continued Figure 5 As shown:

[0034] This utility model provides an advanced small-diameter directional grouting guide device, which includes a base 11, two sets of columns 12, and a crossbeam 13;

[0035] Specifically, an assembly plate 14 is provided above the base 11, and two sets of columns 12 are symmetrically welded to the top of the assembly plate 14. The same set of crossbeams 13 are welded to one side of the two sets of columns 12, and a guide ring 15 is provided between the two sets of columns 12.

[0036] In this embodiment, the base 11 serves as the basic support structure for the entire device. An assembly plate 14 is horizontally mounted above it. Two sets of columns 12 are symmetrically welded to the top of the assembly plate 14 along its central axis. The columns 12 are made of high-strength alloy steel, possessing excellent compressive and torsional resistance, and capable of withstanding various stresses generated during device operation. A set of crossbeams 13 is fixedly installed on the same side of the two sets of columns 12 via welding. The top of the crossbeams 13 serves a load-bearing function, while also enhancing the lateral stability of the columns 12. Together with the columns 12, they form a stable frame structure, effectively improving the overall rigidity of the device.

[0037] Both sets of columns 12 are equipped with sliders 16. One side of each set of sliders 16 is connected to a first transmission mechanism. The bottom of each set of sliders 16 is welded with mounting plates 17. One side of each set of mounting plates 17 is connected to a guide ring 15 through two sets of second transmission mechanisms. A third transmission mechanism is provided between the base 11 and the mounting plate 14.

[0038] Specifically, both sets of columns 12 are provided with lifting grooves 32. Both sets of columns 12 are finely polished to ensure smooth operation of the sliding parts. Both sets of sliders 16 are locked in the two sets of lifting grooves 32. Four sets of limiting grooves 33 are respectively provided on both sides of the inner wall of the two sets of columns 12. Four sets of limiting blocks 34 are welded to the lower ends of both sides of the two sets of sliders 16. The four sets of limiting blocks 34 are connected to the four sets of limiting grooves 33.

[0039] Furthermore, the first transmission mechanism includes a transmission rack 19, a first transmission gear 21, and a first motor 22; two sets of first motors 22 are symmetrically arranged on the top of the crossbeam 13, and two sets of transmission racks 19 are respectively arranged in the two sets of columns 12. Two sets of first transmission gears 21 are respectively connected to the main shafts of the two sets of first motors 22, and the two sets of first transmission gears 21 mesh with the two sets of transmission racks 19 respectively.

[0040] In this embodiment, the second transmission mechanism includes a bearing platform 23, a second motor 24, a second transmission gear 25, a third transmission gear 26, a side bearing 27, and a steering rod 28; two sets of bearing platforms 23 are welded to one side of the two sets of mounting plates 17 respectively, and two sets of second motors 24 are respectively installed on the top of the two sets of bearing platforms 23. The two sets of bearing platforms 23 have slots 37 on adjacent sides, and two sets of side bearings 27 are installed in the two sets of slots 37 respectively. The main shafts of the two sets of second motors 24 are respectively sleeved in the two sets of second transmission gears 25.

[0041] In this embodiment, two sets of steering rods 28 are symmetrically welded to the outer wall of the guide ring 15. One end of each set of steering rods 28 is connected to two sets of side bearings 27. A third transmission gear 26 is provided between each set of bearing platforms 23 and the guide ring 15. The two sets of steering rods 28 are respectively inserted into the two sets of third transmission gears 26. The two sets of third transmission gears 26 are respectively engaged with the two sets of second transmission gears 25.

[0042] Furthermore, the third transmission mechanism includes a third motor 29 and a rotating mechanism 31; the top of the base 11 is provided with the rotating mechanism 31 and the third motor 29, the main shaft of the third motor 29 is connected to the rotating mechanism 31, and the top of the rotating mechanism 31 is connected to the mounting plate 14.

[0043] Understandably, the core working principle of the rotating mechanism 31 lies in achieving precise angular positioning of the bearing platform 23 by driving the slewing bearing structure through a power source. Specifically, the operating mechanism in this embodiment is as follows: the main shaft of the third motor 29 is connected to the input shaft of the rotating mechanism 31 through a coupling or reducer. The rotating mechanism 31 is essentially a high-rigidity crossed roller bearing or slewing bearing. When the third motor 29 is powered on, its main shaft torque drives the inner ring of the rotating mechanism 31 to rotate relative to the outer ring, thereby driving the assembly plate 14 and the entire frame structure welded above it to perform continuous 0-360 degree rotation around the vertical axis.

[0044] In this embodiment, the first motor 22, the second motor 24, and the third motor 29 can all be electrically connected to the same external control module (not shown in the figure). The rotation of the motors is controlled by the signals sent by the external control module, so that the transmission mechanism can be driven to achieve the purpose of adjusting the guidance of the advanced small guide tube.

[0045] In this embodiment, an angle sensor 18 is provided on the top of the guide ring 15.

[0046] Specifically, the top of the guide ring 15 is provided with a mounting base 35, the top of the mounting base 35 has two sets of connecting holes, the top of the mounting base 35 is provided with an angle sensor 18, and the mounting base 35 and the angle sensor 18 are connected by two sets of bolts. The angle sensor 18 can make the tilt angle of the advanced small guide tube more accurate.

[0047] Furthermore, the tilt sensor 18 can be electrically connected to an external control module, so that the electrical signal generated by the tilt sensor 18 can be transmitted to the external control module. In actual use, the user can also electrically connect an external display screen (not shown in the figure) to the external control module. When the external control module receives the electrical signal sent by the tilt sensor 18, it sends the electrical signal to the receiving end of the external display screen. After the external display screen receives the signal, it can display the angle measured by the tilt sensor 18. The user can view the relevant data through the external display screen. The tilt sensor 18 can be a DX1000 model.

[0048] Understandably, when the tilt sensor 18 tilts, the mass block inside the tilt sensor 18 undergoes a slight displacement under the influence of gravity. This displacement is converted into a slight change in electrical signal. The internal circuit detects this signal change and converts it into a corresponding angle value. Two-dimensional tilt angles are typically calculated using mutually orthogonal (X, Y) axis accelerometers.

[0049] In this embodiment, the base 11 has two sets of slots 36 at its bottom, and the mounting plate 14 has six sets of connecting holes at its top, arranged in a circular pattern. The mounting plate 14 is connected to the rotating mechanism 31 by six sets of bolts. When a track is laid on the ground, the two sets of slots 36 can be mounted on the track, enabling movement on the track. This greatly improves construction efficiency while reducing the number of devices and lowering costs.

[0050] When the device in this embodiment is in use, the overall horizontal angle adjustment is first achieved through the third transmission mechanism. The third motor 29 at the top of the base 11 is started, and its main shaft drives the rotating mechanism 31 to rotate, thereby driving the assembly plate 14 and the upper column 12, beam 13 and other structures to rotate horizontally synchronously, so that the guide ring 15 is aligned with the designed grouting position. The rotating mechanism 31 can precisely control the horizontal rotation angle to meet the position adjustment requirements under different working conditions. When the height of the guide ring 15 needs to be adjusted, the two sets of first motors 22 symmetrically arranged on the top of the crossbeam 13 are started. The main shaft of the first motor 22 drives the first transmission gear 21 to rotate. Since the first transmission gear 21 meshes with the transmission rack 19 in the column 12, the rotation of the gear will drive the transmission rack 19 to move in the vertical direction, thereby driving the slider 16, which is locked in the lifting groove 32, to slide up and down. The mounting plate 17 at the bottom of the slider 16 will rise and fall accordingly, thereby adjusting the vertical height of the guide ring 15. During this process, the limiting blocks 34 on both sides of the slider 16 slide in the limiting groove 33 on the inner wall of the column 12, which can prevent the slider 16 from shifting laterally and ensure the stability of the guide ring 15 when it rises and falls. If the tilt angle of the guide ring 15 needs to be adjusted, the second motor 24 on the top of the bearing platform 23 on one side of the mounting plate 17 can be started. The second transmission gear 25 sleeved on the main shaft of the second motor 24 will rotate accordingly. Since the second transmission gear 25 meshes with the third transmission gear 26, the third transmission gear 26 will drive the steering rod 28 passing through it to rotate in the side bearing 27. The steering rod 28 is welded and fixed to the outer wall of the guide ring 15, thereby realizing the angle deflection of the guide ring 15. The entire device realizes multi-dimensional adjustment of the guide ring 15 through the horizontal rotation of the third transmission mechanism, the vertical lifting of the first transmission mechanism, and the angle deflection of the second transmission mechanism, thereby ensuring the accurate orientation of the advanced small guide tube. With the limiting structure of the limiting groove 33 and the limiting block 34, the accuracy of grouting construction can be effectively improved, and it can also cope with different construction scenarios.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
