Description

Technical Field

[0001] This utility model belongs to the field of tunnel grouting drilling technology, and more specifically, it relates to an automatic correction and positioning device for tunnel grouting drilling. Background Technology

[0002] Tunnel grouting boreholes are holes drilled during tunnel construction to carry out grouting operations. They provide a delivery channel for grouting materials (such as cement grout, chemical grout, etc.), allowing the grout to be injected into the surrounding rock or lining gaps of the tunnel. Through grout solidification and bonding of the surrounding rock, filling voids, and sealing seepage, the stability of the surrounding rock is enhanced, its permeability is reduced, and the safety of tunnel construction and operation is ensured. However, traditional tunnel drilling can result in deviations, and the inability to correct these deviations in time can lead to the grouting material not being accurately injected into the target area. This results in incomplete filling of voids in the surrounding rock and failure of seepage sealing, which in turn increases the safety hazards of the project. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an automatic correction and positioning device for tunnel grouting boreholes. This device solves the technical problem in the prior art where traditional tunnel grouting boreholes cannot be corrected in a timely manner, leading to incomplete filling, affecting the filling effect, and increasing the risk of engineering safety hazards.

[0004] The purpose and effectiveness of this utility model's automatic deviation correction and positioning device for tunnel grouting boreholes are achieved through the following specific technical means: An automatic deviation correction and positioning device for tunnel grouting boreholes includes a ring frame. Multiple sets of positioning assembly slots are evenly distributed at the top of the ring frame, and the same set of positioning frames passes through these slots. A positioning borehole is drilled through the center of the ring frame. Multiple assembly parts are provided on the positioning frames corresponding to the positioning borehole. Clamping components are replaced on opposite sides of each set of assembly parts. Multiple sets of mounting platforms are also provided at the bottom of the ring frame. Adjacent platforms of the mounting platforms are inclined, and hydraulic cylinders are mounted on the inclined platforms. Correction components are provided at the shaft ends of the hydraulic cylinders. Multiple sets of connecting parts are flipped at the bottom of the ring frame, and hydraulic sleeves are connected to the ring frame through these connecting parts. Anchoring legs pass through the hydraulic sleeves. Two sets of auxiliary positioning components are also provided at the bottom of the ring frame between the multiple sets of connecting parts.

[0005] The above technical solution further includes that the assembly is disassembled and passed through the positioning frame, and is fixedly connected to the positioning frame by screws; the assembly is provided with an assembly groove on the side away from the positioning frame, and the clamping member is spherical on one side and passes through the assembly groove.

[0006] The above technical solution further includes that the clamping member and the correction member are both arc-shaped on the same side away from the positioning frame. When multiple sets of the assembly are installed on the positioning frame, and when the ends of multiple sets of hydraulic cylinders are clamped synchronously, the multiple sets of clamping members and the multiple sets of correction members respectively form a ring shape on the positioning frame.

[0007] The above technical solution further includes that the connector has a V-shaped structure, and mounting posts are provided on both sides of the connector. The bottom end of the ring frame is provided with multiple sets of mounting grooves. The connector is rotatably installed in the mounting grooves through the mounting posts. When the hydraulic sleeve is in a vertical state, one side of the connector contacts the mounting groove.

[0008] The above technical solution further includes that the anchoring leg is provided with a piston block and a ground cone at both ends, the hydraulic sleeve is provided with an end cap at the bottom end, the piston block of the anchoring leg passes through the end cap and is installed inside the hydraulic sleeve, the ground cone is also provided with multiple sets of assembly holes, and each of the multiple sets of assembly holes is provided with an expansion anchor bolt; the bottom end of the end cap is also provided with a multi-tooth anchor grabbing structure.

[0009] The above technical solution further includes that both sets of auxiliary positioning components are fan-shaped structures with mounting components at the top, and the bottom of the ring frame is provided with a ring groove. Both sets of auxiliary positioning components are installed in the ring groove through the mounting components. The bottom of the auxiliary positioning component is also provided with multiple sets of auxiliary positioning anchor rods.

[0010] The above technical solution further includes that the bottom end of the ring frame between the two sets of auxiliary positioning components is provided with two sets of positioning grooves, and the two sets of positioning grooves are respectively provided with tilt sensors and laser sensors, and protective covers are provided on the tilt sensors and the laser sensors.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The clamping components connected to the positioning frame work in conjunction with the correction components driven by the hydraulic cylinder at the bottom of the ring frame to form a circular structure that limits the drilling components. Inclination sensors and laser sensors monitor the drilling status in real time. After data feedback, the hydraulic cylinder drives the correction components to adjust, achieving automatic correction and positioning during the drilling process, ensuring the borehole reaches the target area. Grouting material is injected into the tunnel surrounding rock or lining gaps through the borehole. After solidification, the grout fully cements the surrounding rock, fills voids, seals seepage, enhances the stability of the surrounding rock, and reduces its permeability.

[0012] 2. The hydraulic sleeve is connected via connectors. The ground cone of the anchor leg inside the sleeve is fixed with expansion bolts. The multi-toothed anchoring structure on the end cap enhances the fixing effect. The auxiliary positioning component is installed in the ring groove of the ring frame via mounting components. The bottom auxiliary positioning anchor rod further reinforces the device, achieving overall stable fixing. The assembly is fixed to the positioning frame with screws. The clamping component is spherical and inserted into the assembly groove, adaptable to different specifications of drilling components. The tilt sensor and laser sensor are protected by protective covers. The auxiliary positioning component can be adjusted along the ring groove, improving the device's adaptability and durability, ensuring long-term stable operation. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0022] like Figures 1 to 7As shown, this utility model provides an automatic correction and positioning device for tunnel grouting boreholes, including a ring frame 1. Multiple sets of positioning assembly slots are evenly distributed at the top of the ring frame 1, and the same set of positioning frames 101 are inserted into these slots. A positioning borehole is drilled through the center of the ring frame 1. Multiple assembly parts 102 are provided on the positioning frames 101 corresponding to the positioning borehole. Clamping parts 103 are replaced on the opposite side of each assembly part 102. Multiple sets of mounting platforms are also provided at the bottom of the ring frame 1. The adjacent surfaces of the mounting platforms are inclined, and hydraulic cylinders 2 are provided on the inclined surfaces of each mounting platform. Correction parts 104 are provided at the shaft ends of each hydraulic cylinder 2. Multiple sets of connecting parts are flipped at the bottom of the ring frame 1. Hydraulic sleeves 3 are connected to the ring frame 1 through the connecting parts, and anchoring legs 105 are inserted into the hydraulic sleeves 3. Two sets of auxiliary positioning parts 4 are also provided at the bottom of the ring frame 1 between the multiple sets of connecting parts. The top positioning assembly slot of the ring frame 1 provides an installation base for the positioning frame 101. Multiple sets of positioning assembly slots ensure that the positioning frame 101 remains horizontal and stable after installation, preventing it from shifting under stress. The positioning frame 101 is equipped with multiple assembly parts 102 corresponding to the positioning drill holes. Clamping parts 103 are inserted on opposite sides of the assembly parts 102. The multiple assembly parts 102 cooperate with the clamping parts 103 to encircle and limit the drilled component passing through the positioning drill hole, restricting its radial displacement and ensuring that the initial position of the drilled component coincides with the axis of the positioning drill hole. The clamping parts 103 are replaceable and can adapt to drilled components of different diameters, expanding the applicability of the lifting device.

[0023] The bottom mounting platform of the ring frame 1 is inclined, and the hydraulic cylinder 2 is mounted on the inclined platform, so that the axis of the hydraulic cylinder 2 forms a certain angle with the axis of the positioning drill hole. The shaft end of the hydraulic cylinder 2 is connected to the correction component 104. During the drilling process, if the drilling component deviates, the extension and retraction of the hydraulic cylinder 2 at the corresponding position can be adjusted to drive the correction component 104 to push the drilling component back to the preset axis position, thus achieving drilling correction. Multiple sets of hydraulic cylinders 2 and correction components 104 cooperate to apply force to the drilling component from different angles, ensuring a smooth correction process, avoiding damage or secondary displacement of the drilling component due to single-point force, and ensuring the continuity of the drilling process.

[0024] The bottom connector of the ring frame 1 is flip-up, allowing the hydraulic sleeve 3 to be adjusted in installation angle to adapt to tunnel construction faces with different slopes. Anchor legs 105 are inserted inside the hydraulic sleeve 3. The anchor legs 105 can move along the axis of the hydraulic sleeve 3, adjusting their extension length to meet different depth fixing requirements. By inserting the anchor legs 105 into the tunnel surrounding rock or ground, the ring frame 1 can be fixedly connected to the construction face, limiting the overall displacement of the ring frame 1 and preventing positioning deviations caused by the shaking of the ring frame 1 during drilling. The flip-up connector structure allows the hydraulic sleeve 3 to be folded and stored when not in use, reducing the space occupied by the device and facilitating transportation and storage.

[0025] Two sets of auxiliary positioning components 4 are installed between multiple sets of connecting parts. The auxiliary positioning components 4 cooperate with the hydraulic sleeve 3 and the anchoring leg 105 to form a multi-point fixing structure, improving the installation stability of the ring frame 1. Multi-point fixing can disperse the drilling reaction force borne by the ring frame 1, avoiding excessive force on a single point of fixing that could lead to loosening, and ensuring that the ring frame 1 remains stable throughout the drilling process. The auxiliary positioning components 4 are connected to the ring frame 1, further restricting the displacement of the ring frame 1 in the horizontal and vertical directions. Together with the radial limiting of the positioning frame 101 and the clamping component 103, the correction effect of the hydraulic cylinder 2 and the correction component 104, and the fixing effect of the hydraulic sleeve 3 and the anchoring leg 105, they work synergistically to comprehensively ensure drilling accuracy and construction safety.

[0026] The hydraulic sleeve 3 is connected to the hydraulic cylinder 2 via an external hydraulic mechanism, which provides stable and adjustable hydraulic power. The external hydraulic mechanism can output different pressures and flow rates as needed, enabling the hydraulic cylinder 2 to drive the correction component 104 to extend and retract, ensuring that the correction force and speed are controllable; at the same time, it provides sufficient power for the movement of the anchor leg 105 inside the hydraulic sleeve 3, ensuring that the anchor leg 105 extends and is fixed quickly and stably.

[0027] The entire device is connected to an external control module, enabling centralized control. After receiving relevant monitoring data, the control module can synchronously regulate the extension and retraction of multiple sets of hydraulic cylinders 2 to ensure coordinated correction processes; it can also control the extension, retraction, and fixation of the anchoring legs 105, achieving linkage between the overall positioning of the device and drilling correction, thus improving operational convenience and work efficiency.

[0028] like Figure 2 , Figure 5 and Figure 7 As shown, the assembly 102 is detachably mounted on the positioning frame 101 and fixedly connected to the positioning frame 101 with screws. An assembly groove is provided on the side of the assembly 102 away from the positioning frame 101, and the clamping member 103 is spherical on one side and passes through the assembly groove. The assembly 102 is detached from the positioning frame 101 and fixed with screws, allowing the assembly 102 to be removed from the positioning frame 101. When the assembly 102 is damaged, it can be replaced individually without replacing the entire positioning frame 101, reducing maintenance costs. Different specifications of the assembly 102 can be installed alternately to adapt to different scenario requirements, improving the versatility of the device.

[0029] The assembly 102 has an assembly groove on the side away from the positioning frame 101, and the clamping member 103 has a spherical shape that passes through the assembly groove on one side. The spherical structure allows the clamping member 103 to rotate within the assembly groove. When the clamping member 103 contacts the drilling component, it can adapt to the surface curvature of the drilling component, increasing the contact area. The clamping member 103 fits more tightly with the drilling component, providing a more stable limiting effect and preventing the drilling component from shifting. The assembly 102 is fixed with screws, and the fixing force of the assembly 102 on the positioning frame 101 can be adjusted to ensure that the assembly 102 is connected to the positioning frame 101 and prevent the assembly 102 from loosening under force.

[0030] Both the clamping member 103 and the correction member 104 are arc-shaped on the same side away from the positioning frame 101. When multiple assembly parts 102 are installed on the positioning frame 101, and when the ends of multiple sets of hydraulic cylinders 2 are clamped synchronously, the multiple sets of clamping members 103 and multiple sets of correction members 104 form rings on the positioning frame 101. The clamping member 103 and the correction member 104 are arc-shaped on the side away from the positioning frame 101. After the multiple assembly parts 102 are installed on the positioning frame 101, the multiple sets of clamping members 103 form a ring. The ring structure matches the outer circle of the drilling component, increasing the contact area between the clamping member 103 and the drilling component, ensuring uniform force on the drilling component, and preventing deformation of the drilling component due to localized force. The ring formed by the clamping member 103 radially limits the drilling component, restricting radial displacement of the drilling component during drilling and ensuring the initial drilling position.

[0031] When multiple sets of hydraulic cylinders 2 clamp synchronously at their ends, multiple sets of correction components 104 form a ring. This ring structure ensures uniform contact between the correction components 104 and the drilling component. When the hydraulic cylinders 2 drive the correction components 104, they can apply force to the drilling component from multiple directions, ensuring that the correction force is evenly transmitted to the drilling component. When there is a deviation in a single direction, the corresponding hydraulic cylinder 2 actuates, and the correction component 104 pushes the drilling component back to its axis. When there is a deviation in multiple directions, multiple sets of hydraulic cylinders 2 act collaboratively to prevent secondary deviation of the drilling component during the correction process.

[0032] The clamping component 103 and the correction component 104 each form a ring, creating a double-limiting structure. The ring formed by the clamping component 103 is responsible for initial positioning and limiting, while the ring formed by the correction component 104 is responsible for dynamic correction and adjustment. Together, they achieve position control throughout the drilling process. The ring structure is adaptable to drilling components of different diameters. As long as the diameter of the drilling component is within the inner diameter range of the ring, it can be clamped and fixed by the clamping component 103 and the correction component 104, improving the device's adaptability to drilling components of different specifications and reducing the frequency of component replacement.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, the connector has a V-shaped structure, with mounting posts on both sides. The bottom of the ring frame 1 has multiple mounting slots, and the connector is rotatably installed within these slots via the mounting posts. When the hydraulic sleeve 3 is in a vertical position, one side of the connector contacts the mounting slot. The connector's V-shaped structure and mounting posts on both sides, along with the mounting slots at the bottom of the ring frame 1, allow the connector to rotate around the mounting posts. This rotation of the connector causes the hydraulic sleeve 3 to adjust its angle, adapting to different slopes in the tunnel. This eliminates the need to replace the connector, meeting diverse installation requirements and improving the device's adaptability.

[0034] When the hydraulic sleeve 3 is vertical, one side of the connector contacts the mounting groove. The mounting groove limits the connector, restricting its rotation and ensuring that the hydraulic sleeve 3 remains stable and vertical. This provides a guarantee for the vertical insertion of the anchor leg 105 into the surrounding rock or ground, improving the fixing effect of the anchor leg 105. The V-shaped structure makes the force on the connector more even. The anchoring force transmitted by the hydraulic sleeve 3 is distributed to the ring frame 1 through the connector, avoiding localized force concentration on the ring frame 1 and causing damage. The rotational installation method simplifies the connector assembly and disassembly process. When the connector is damaged, it can be disassembled and replaced individually, reducing maintenance difficulty and cost, and ensuring the overall service life of the device.

[0035] The anchoring leg 105 has a piston block and a ground cone at each end. The bottom of the hydraulic sleeve 3 has an end cap. The piston block of the anchoring leg 105 passes through the end cap and is installed inside the hydraulic sleeve 3. The ground cone also has multiple sets of assembly holes, each containing an expansion anchor bolt 501. The bottom of the end cap also has a multi-tooth gripping anchor structure. The piston block, installed inside the hydraulic sleeve 3, is hydraulically driven to move, causing the ground cone to extend or retract. The ground cone inserts into the surrounding rock or ground surface, providing basic anchoring force for the ring frame 1, limiting the displacement of the ring frame 1, and ensuring stability during the drilling process. The hydraulic drive makes the extension and retraction of the ground cone controllable, adapting to different anchoring depth requirements.

[0036] An expansion anchor 501 is installed inside the ground cone assembly hole. After the ground cone is inserted, the expansion anchor 501 expands and is fixed in the stratum, increasing the contact area between the ground cone and the stratum, improving the overall anchoring strength of the anchor leg 105, and preventing the anchor leg 105 from loosening under stress. The multi-toothed gripping anchor structure of the end cap contacts the ground, further enhancing the fixing effect of the hydraulic sleeve 3, and forming a double anchoring with the ground cone to disperse the anchoring force.

[0037] The end cap seals the bottom of the hydraulic sleeve 3 to prevent impurities from entering the interior of the hydraulic sleeve 3 and to avoid obstruction of the piston block's movement. The expansion anchor bolt 501 is removable and replaceable; it can be replaced individually when damaged, reducing maintenance costs. The multi-toothed anchoring structure, in conjunction with the expansion anchor bolt 501, ensures that the anchoring leg 105 can be stably fixed under different geological conditions, improving the device's environmental adaptability.

[0038] like Figures 3 to 4 As shown, both sets of auxiliary positioning components 4 are fan-shaped structures with mounting parts at the top. The bottom of the ring frame 1 has an annular groove, and both sets of auxiliary positioning components 4 are installed within the annular groove via the mounting parts. Multiple sets of auxiliary positioning anchor rods 601 are also provided at the bottom of the auxiliary positioning components 4. The fan-shaped structure of the two sets of auxiliary positioning components 4, with the top mounting parts engaging with the annular groove at the bottom of the ring frame 1, allows the auxiliary positioning components 4 to slide along the annular groove, adjusting their circumferential position. In different construction scenarios, the spacing between the two sets of auxiliary positioning components 4 can be adjusted according to anchoring requirements, adapting to different fixing point requirements and improving the installation flexibility of the device.

[0039] Multiple sets of auxiliary positioning anchors 601 are installed at the bottom of the auxiliary positioning component 4. These anchors 601 are inserted into the surrounding rock or ground to provide additional anchoring points for the ring frame 1. Together with the anchoring legs 105, they form a multi-point anchoring system, dispersing the borehole reaction force borne by the ring frame 1, preventing excessive stress on a single anchor point that could lead to loosening, and enhancing the overall stability of the device. The fan-shaped structure allows the auxiliary positioning component 4 to fit snugly against the bottom of the ring frame 1, reducing installation gaps and improving positioning accuracy. The mating structure between the mounting component and the ring groove simplifies the assembly and disassembly process of the auxiliary positioning component 4; damaged components can be individually disassembled and replaced, reducing maintenance costs. Multiple sets of auxiliary positioning anchors 601 expand the anchoring coverage area, adapting to different geological conditions and ensuring anchoring effectiveness.

[0040] Two sets of positioning grooves are also provided at the bottom of the ring frame 1 between the two sets of auxiliary positioning components 4. An inclination sensor 5 and a laser sensor 6 are respectively installed in the two sets of positioning grooves, and both the inclination sensor 5 and the laser sensor 6 are covered with protective covers. The inclination sensor 5 monitors the tilt state of the ring frame 1, and the laser sensor 6 monitors the axial deviation of the drilling components. The data from the two sets of sensors are combined to provide a basis for drilling correction. After receiving the data, the controller adjusts the hydraulic cylinder 2 to achieve automatic correction, improve drilling accuracy, and avoid deviation problems caused by the lag of manual monitoring. The protective covers on the sensors isolate dust and slurry generated during construction, preventing surface contamination of the sensors from affecting monitoring accuracy. The protective covers block external impacts, preventing sensor damage and extending service life. The protective covers are removable, not affecting sensor maintenance, calibration, or replacement, reducing maintenance difficulty and ensuring continuous and stable sensor operation. The inclination sensor 5 can be a BWH516 model sensor; the laser sensor 6 can be an FTM-50S model sensor.

[0041] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
