Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, specifically to an integrated platform for measuring the emission of harmful gases during advanced drilling. Background Technology

[0002] With the continuous construction of tunnels in mountainous areas, the proportion of tunnels threatened by hazardous gases is constantly increasing, making this engineering geological issue of hazardous gases a necessity during tunnel construction. During tunnel construction, to accurately determine the gas level within the tunnel and ensure safe and efficient excavation, pre-drilling is typically used to assess the hazardous gas hazard before formal excavation at the tunnel face. However, due to limitations in borehole diameter and the complex environment within the borehole, it is difficult to place hazardous gas sensors inside. Traditional methods for pre-detection of hazardous gases typically include: 1. After reaching the designed depth, sealing the borehole for 24 hours before measuring the concentration of hazardous gases; 2. Placing contact-type hazardous gas sensors at the borehole opening to measure the concentration of hazardous gases.

[0003] The first method has the following drawbacks: Firstly, the sealing operation is time-consuming, which significantly impacts the overall project schedule and hinders progress. Secondly, during the long drilling process, a large amount of harmful gas gradually dissipates from the borehole, making it difficult to accurately measure the actual concentration of harmful gases later. Furthermore, soluble harmful gases are discharged with the water flow within the borehole, further increasing the difficulty of accurate measurement and making it hard to obtain reliable concentration data. The second method has the following drawbacks: Because advanced drilling is generally quite deep, with the deepest holes reaching hundreds of meters, the concentration of harmful gases emerging from newly revealed formations differs significantly between the borehole opening and the bottom, leading to a large error when using contact-type harmful gas sensors to detect gas concentration at the borehole opening.

[0004] To accurately detect the concentration of harmful gases within pre-drilled boreholes, the applicant has filed an invention patent application (application number 202510100207.4) entitled "A Harmful Gas Detection Device and Method for Pre-drilled Tunnels." The detection device includes a casing with a laser monitoring module mounted on it. This module emits a laser along the axial direction of the casing and performs distance measurement and monitoring of harmful gas concentration. The casing also includes a blocking module for periodically blocking the laser emitted by the monitoring module and a gas flow velocity monitoring module for monitoring the flow velocity of harmful gases within the casing. This detection device can accurately detect the concentration of harmful gases at the bottom of pre-drilled boreholes, providing a basis for assessing the hazardous gas hazard in tunnels. However, since the detection equipment is separate from the drilling rig, the two need to be temporarily connected before drilling. The connection process requires multiple steps such as leveling, centering, and tightening, which significantly increases the drilling preparation time. In addition, the centering accuracy of the detection equipment and the drilling rig is highly dependent on human experience. Slight carelessness can lead to poor coaxial accuracy between the two, resulting in an angle between the laser beam path and the drilling axis, which introduces systematic measurement errors and affects the accuracy of the final detection results. Utility Model Content

[0005] The purpose of this application is to provide an integrated drilling and measurement platform for the emission of harmful gases in advanced boreholes, which solves the problems of increased borehole preparation time and easy introduction of systematic measurement errors due to the separation of the detection equipment from the drilling rig.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] An integrated drilling and measurement platform for the emission of harmful gases during advanced drilling includes a detection device, a drilling rig, and a drill rod mounted on the drilling rig. The detection device includes a casing and a laser monitoring module, a shielding module, and a gas flow rate monitoring module mounted on the casing. It also includes a walking system, a lifting and angle adjustment system mounted on the walking system, a drilling platform mounted on the lifting and angle adjustment system, and a drilling machine mounted on the drilling platform. The drilling rig and the casing are coaxially arranged and respectively fixed on the drilling machine. The drill rod passes through the inner cavity of the casing.

[0008] Furthermore, the drilling machine is provided with a support seat located between the drilling rig and the casing and away from the drilling rig. The support seat is movably connected to the drill rod and is used to radially limit the drill rod. The drill rod can rotate and move axially relative to the support seat.

[0009] Furthermore, the casing is provided with a flange support assembly at one end facing the drilling rig. The flange support assembly is movably connected to the drill rod and is used to radially limit the drill rod. The drill rod can rotate and move axially relative to the flange support assembly. The bottom of the casing is provided with a slag discharge and water outlet pipe communicating with its inner cavity.

[0010] Furthermore, the walking system is also equipped with a water tank, and the slag discharge pipe is connected to the water tank through a first flexible pipe. The water tank is equipped with a sampling pipe, and the sampling pipe is equipped with a sampling valve and a flow meter.

[0011] Furthermore, the walking system is equipped with a water pump, the inlet of which is connected to the water tank, and the outlet of which is connected to the water inlet of the drilling rig through a second flexible pipe.

[0012] Furthermore, the water tank is provided with multiple sedimentation chambers in sequence, and adjacent sedimentation chambers are connected by an overflow channel. The height of the bottom of the overflow channel gradually decreases along the direction from the first sedimentation chamber to the last sedimentation chamber; the first flexible pipe is connected to the first sedimentation chamber.

[0013] Furthermore, the number of sampling tubes corresponds to the number of sedimentation chambers and is one-to-one with each other; each sampling tube is connected to the corresponding sedimentation chamber; each sedimentation chamber is connected to the inlet of the water pump through a water pumping branch pipe, and the water pumping branch pipe is equipped with a water pumping valve.

[0014] Furthermore, the walking system includes a tracked chassis, a platform slewing mechanism mounted on the tracked chassis, and a carrying platform mounted on the platform slewing mechanism, with the lifting and angle adjustment system mounted on the carrying platform.

[0015] Furthermore, the lifting and angle adjustment system includes a robotic arm, a lifting cylinder, and a swing cylinder. The lower end of the robotic arm is hinged to the walking system, and the upper end of the robotic arm is hinged to the bottom of the drilling platform. The lifting cylinder is hinged between the robotic arm and the walking system and is used to drive the robotic arm to rotate up and down in the vertical plane. The swing cylinder is hinged between the robotic arm and the drilling platform and is used to drive the drilling platform to swing up and down in the vertical plane.

[0016] Furthermore, the walking system is equipped with a drill rod storage basket.

[0017] The beneficial effects of this application are:

[0018] The integrated drilling and measurement platform for detecting harmful gas emissions during pre-drilling provided in this application eliminates the need for secondary installation, leveling, alignment, and tightening by coaxially mounting the casing of the drilling rig and detection equipment on the drilling machine. This reduces pre-drilling preparation time and ensures high alignment accuracy between the detection equipment and the drilling rig, preventing angles between the laser path and the borehole axis caused by manual alignment errors. This prevents the introduction of systematic measurement errors and improves the accuracy of the final detection results. The platform's mobility system allows it to move automatically to the drilling location without the need for cranes or manual handling, reducing worker workload. Furthermore, the lifting and angle adjustment system allows for free adjustment of the drill rod's position and angle according to the location and angle of the borehole, enhancing the platform's versatility.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] See Figure 1 , Figure 2 , Figure 3 This application provides an integrated platform for measuring the emission of harmful gases during pre-drilling, including a detection device 10, a drilling rig 11, and a drill rod 12 mounted on the drilling rig 11. The detection device 10 includes a casing 101 and a laser monitoring module 102, a shielding module 103, and a gas flow rate monitoring module 104 mounted on the casing 101. It also includes a walking system 13, a lifting and angle adjustment system 14 mounted on the walking system 13, a drilling platform 15 mounted on the lifting and angle adjustment system 14, and a drilling machine 16 mounted on the drilling platform 15. The drilling rig 11 and the casing 101 are coaxially arranged and respectively fixed on the drilling machine 16. The drill rod 12 passes through the inner cavity of the casing 101.

[0043] The walking system 13 is used to move the entire drilling and surveying integrated platform on the ground to the vicinity of the pre-drilling point. Exemplarily, the walking system 13 may include a tracked walking system and a wheeled walking system. A lifting and adjusting system 14 is installed on the walking system 13, and the drilling platform 15 is installed on the lifting and adjusting system 14. The lifting and adjusting system 14 allows adjustment of the height of the drilling platform 15 and its angle with the horizontal plane, providing an operating platform for workers performing high-altitude drilling. The drilling platform 15 can adopt a frame structure or a flat plate structure from the prior art, without specific limitations. A fence 151 is installed around the drilling platform 15, forming a physical barrier at the edge of the drilling platform 15 to prevent workers from falling from the edge of the drilling platform 15, thus improving construction safety.

[0044] Drilling machine 16 is mounted on drilling platform 15 for mounting and supporting detection equipment 10 and drilling rig 11. Drilling machine 16 has a long, straight, elongated structure and can be welded from structural steel. Drilling rig 11 is mounted on top of one end of drilling machine 16 using bolts or other fasteners, with the axis of drilling rig 11 parallel to the length of drilling machine 16. Drill rod 12 is mounted on drilling rig 11, and is parallel to the length of drilling machine 16; a drill bit 121 is mounted at one end of drill rod 12.

[0045] The detection device 10 refers to the detection device disclosed in application number 202510100207.4, entitled "A Detection Device and Method for Harmful Gases in Tunnel Advanced Drilling", which mainly includes a casing 101, a laser monitoring module 102, a shielding module 103, and a gas flow rate monitoring module 104.

[0046] The casing 101 has an open-end structure. It is coaxially mounted with the drilling rig 11 and installed above the other end of the drill press 16 using bolts or other fasteners. This allows the drill rod 12 to pass through the casing 101, ensuring that the drill rod 12 is parallel to the casing 101 and forming an annular channel between them. The portion of this annular channel below the drill rod 12 serves as a slag removal channel, while the portion above the drill rod 12 serves as a detection channel for harmful gases. In this embodiment, the inner diameter of the casing 101 is larger than the outer diameter of the drill rod 12 and matches the diameter of the borehole.

[0047] The laser monitoring module 102, the shielding module 103, and the gas flow rate monitoring module 104 are all installed on the casing 101. The laser monitoring module 102 is used to emit a laser along the axial direction of the casing 101 towards the drill bit 121 within the casing 101, and to measure distance and monitor the concentration of harmful gases. The shielding module 103 is used to periodically shield the laser emitted by the laser monitoring module. The gas flow rate monitoring module 104 is used to monitor the flow rate of harmful gases within the casing 101. The laser monitoring module 102, the shielding module 103, and the gas flow rate monitoring module 104 are all structures disclosed in application number 202510100207.4, entitled "A Harmful Gas Detection Device and Method for Tunnel Pre-drilling".

[0048] See Figure 1 This application provides an integrated platform for measuring the emission of hazardous gases in pre-drilled boreholes. This platform is used for pre-drilling before the formal excavation of the tunnel face and can accurately detect the concentration of hazardous gases at the bottom of the pre-drilled borehole in real time, providing accurate data for assessing the hazardous gas hazard in tunnels. The specific working principle is as follows:

[0049] The control walking system 13 moves the entire drilling and surveying integrated platform to the vicinity of the pre-drilling point. The control lifting and angle adjustment system 14 adjusts the height and angle of the drilling platform 15 to meet the drilling requirements, and the front end of the casing 101 is pressed tightly against the drilling rock wall. The gap between the casing 101 and the drilling rock wall is sealed using sealant or other filling materials. The drilling rig 11 is started, and the drilling rig 11 drives the drill rod 12 to drive the drill bit 121 to drill a hole in the drilling rock wall. The drill cuttings generated during the drilling process are discharged from the rear end of the casing 101. After drilling is completed, the laser monitoring module 102, the shielding module 103, and the gas flow rate monitoring module 104 are activated to detect the concentration of harmful gases at the bottom of the pre-drilled hole using the cooperation of the three. The specific detection method for the concentration of harmful gases at the bottom of the hole can refer to the detection method disclosed in application number 202510100207.4, entitled "A Harmful Gas Detection Device and Method for Pre-drilling in Tunnels", and will not be repeated here.

[0050] The integrated drilling and measurement platform for detecting harmful gas emission during pre-drilling provided in this application embodiment, by coaxially arranging the drilling rig 11 and the casing 101 of the detection device 10 and fixing them respectively on the drilling machine 16, eliminates the need for secondary installation, leveling, alignment, and fastening, reducing preparation time before drilling. Furthermore, it ensures high alignment accuracy between the detection device 10 and the drilling rig 11, avoiding the angle between the laser beam path and the borehole axis caused by manual alignment errors, preventing the introduction of systematic measurement errors, and improving the accuracy of the final detection results. The walking system 13 allows the integrated drilling and measurement platform to be moved to the drilling location automatically, without the need for cranes or manual handling, reducing the labor intensity of workers. The lifting and angle adjustment system 14 allows the position and angle of the drill rod 12 to be freely adjusted according to the position and angle of the borehole, improving the applicability of the integrated drilling and measurement platform.

[0051] In some embodiments, see Figure 2 , Figure 3 The drill press 16 is provided with a support seat 17 located between the drill rig 11 and the casing 101 and away from the drill rig 11. The support seat 17 is movably connected to the drill rod 12 and is used to radially limit the drill rod 12. The drill rod 12 can rotate and move axially relative to the support seat 17.

[0052] Specifically, the support base 17 can be a vertically arranged support plate. The lower end of the support plate is fixedly connected to the drill press 16. The support plate is provided with a support hole. The drill rod 12 passes through the support hole and can rotate and move axially within the support hole. Thus, the support hole is used to support and radially limit the drill rod 12.

[0053] Accordingly, by setting up a support base 17, an additional fulcrum is formed between the drilling rig 11 and the casing 101, and adjacent to the casing 101, reducing the overhang length of the drill rod 12, lowering the bending moment, suppressing the lateral sway and buckling of the drill rod 12, and improving the coaxiality between the drill rod 12 and the casing 101. The support base 17 only provides radial constraint and does not restrict the rotation and axial feed of the drill rod 12, thus ensuring normal drilling operations.

[0054] In some embodiments, see Figure 2 , Figure 3 The casing 101 is provided with a flange support assembly 105 at one end facing the drilling rig 11. The flange support assembly 105 is movably connected to the drill rod 12 and is used to radially limit the drill rod 12. The drill rod 12 can rotate and move axially relative to the flange support assembly 105. The bottom of the casing 101 is provided with a slag discharge and water outlet pipe 106 communicating with its inner cavity.

[0055] Specifically, the flange support assembly 105 may include a flange welded to the rear end of the sleeve 101, a flange cover that is sealed to the flange and connected to it by fasteners such as bolts, the flange cover having a central hole through which the drill rod 12 passes and can rotate and move axially within the central hole, thereby using the central hole to support and radially limit the drill rod 12.

[0056] Correspondingly, by setting the flange support assembly 105, a second fulcrum is formed at the rear end of the casing 101, which cooperates with the support seat 17 to further reduce the overhang length of the drill rod 12 to suppress the lateral swing and bending of the drill rod 12, ensure the coaxiality between the drill rod 12 and the casing 101, and improve the straightness of the borehole; the flange support assembly 105 can also seal the rear end of the casing 101 and allow the drill cuttings and water generated during the drilling process to be discharged through the slag discharge and water outlet pipe 106.

[0057] In some embodiments, see Figure 4 , Figure 5 The walking system 13 is also equipped with a water tank 18. The slag discharge pipe 106 is connected to the water tank 18 through a first flexible pipe 19. The water tank 18 is equipped with a sampling pipe 20, and the sampling pipe 20 is equipped with a sampling valve 21 and a flow meter 22. The sampling valve 21 is used to control the opening and closing of the sampling pipe 20. The first flexible pipe 19 can be a corrugated pipe.

[0058] Correspondingly, by setting a water tank 18 on the walking system 13 and connecting the slag discharge pipe 106 to the water tank 18 through the first flexible pipe 19, on the one hand, the drilling slag and water generated during the drilling process can be introduced into the water tank 18 to avoid on-site overflow; on the other hand, the first flexible pipe 19 can adapt to drilling at different heights to ensure smooth water flow.

[0059] In some embodiments, see Figure 4The walking system 13 is equipped with a water pump 23. The inlet of the water pump 23 is connected to the water tank 18, and the outlet of the water pump 23 is connected to the water inlet of the drilling rig 11 through the second flexible pipe 24.

[0060] Correspondingly, the water tank 18 has a large volume, providing a still water zone. Drill cuttings fall into the water tank 18 and settle quickly. The water pump 23 can directly draw the settled water from the tank and transport it to the drilling rig 11 for recycling through the second flexible pipe 24, reducing the consumption of fresh water. The second flexible pipe 24 can be a corrugated pipe. The expansion and bending performance of the corrugated pipe can adapt to the raising and lowering of the drilling rig, ensuring a continuous supply of return water without disassembling the pipeline. At the same time, the corrugated pipe is highly flexible and fatigue-resistant, reducing the risk of joint leakage.

[0061] When there are fissures in the stratum, the circulating water in the water tank 18 may be insufficient. In order to replenish the circulating water in the water tank 18, the water tank 18 is provided with a water supply pipe 28 that communicates with its inner cavity, and the water supply pipe 28 is provided with a water supply valve 29 that controls its opening and closing.

[0062] In some embodiments, see Figure 6 The water tank 18 is equipped with multiple sedimentation chambers 181 arranged sequentially. Adjacent sedimentation chambers 181 are connected by an overflow channel 182. The bottom of the overflow channel 182 gradually decreases in height from the first sedimentation chamber 181 to the last sedimentation chamber 181. The first flexible pipe 19 is connected to the first sedimentation chamber 181. The last sedimentation chamber 181 can be connected to the inlet of the water pump 23.

[0063] For details, see Figure 6 The water tank 18 has several partitions 183 arranged from right to left. The lower end of the partition 183 is connected to the bottom wall of the water tank 18 and divides the inner cavity of the water tank 18 into several sedimentation chambers 181. There is a gap between the upper end of the partition 183 and the top wall of the water tank 18, forming an overflow channel 182. The height of the top of the partitions 183 gradually decreases from right to left, thereby making the height of the bottom of the overflow channel 182 gradually decrease from right to left, so as to form a multi-stage sedimentation chamber 181 in the inner cavity of the water tank 18.

[0064] Correspondingly, the multi-stage sedimentation chambers 181 are arranged in series. After the drill cuttings water enters the first-stage sedimentation chamber 181 through the first flexible pipe 19, the drill cuttings settle sequentially along the gradually decreasing overflow channels 182, and the clear water finally enters the final-stage sedimentation chamber 181, achieving solid-liquid separation. The water pump 23 can directly draw in the final-stage clear water, reducing the probability of drill cuttings being sucked into the water pump 23 and improving the service life of the water pump 23.

[0065] In some embodiments, see Figure 5The number of sampling tubes 20 corresponds to the number of sedimentation chambers 181, and each sampling tube 20 is connected to its corresponding sedimentation chamber 181. Each sedimentation chamber 181 is connected to the inlet of the water pump 23 via a water pumping branch pipe 25, and a water pumping valve 26 is provided on the water pumping branch pipe 25. The water pumping valve 26 is used to control the opening and closing of the water pumping branch pipe 25.

[0066] Correspondingly, each settling chamber 181 is independently equipped with a sampling tube 20, allowing for sampling from each settling chamber 181 as needed. Each settling chamber 181 is connected in parallel to the water pump 23 via a water pumping branch pipe 25. The water pumping valve 26 on each water pumping branch pipe 25 can be opened and closed independently. By controlling each water pumping valve 26, water intake can be switched as needed, improving the applicability of drilling in different formations. For example, when a large amount of drill cuttings is discharged during drilling, more settling chambers 181 can be used to settle the drill cuttings, minimizing the probability of the drill cuttings being sucked into the water pump 23; when a small amount of drill cuttings is discharged during drilling, the probability of the drill cuttings being sucked into the water pump 23 is low, so fewer settling chambers 181 can be used to settle the drill cuttings, reducing the water circulation path and improving circulation efficiency.

[0067] In some embodiments, see Figure 1 The walking system 13 includes a tracked chassis 131, a platform slewing mechanism 132 mounted on the tracked chassis 131, a carrying platform 133 mounted on the platform slewing mechanism 132, and a lifting and angle adjustment system 14 mounted on the carrying platform 133.

[0068] Correspondingly, the tracked chassis 131 can move on the ground via tracks, providing all-terrain mobility; the platform slewing mechanism 132 is mounted on the tracked chassis 131, and the carrying platform 133 is mounted on the platform slewing mechanism 132. The platform slewing mechanism 132 allows the carrying platform 133 to rotate 360°, adjusting the orientation of the lifting and angle adjustment system 14. A control room is located on the carrying platform 133, and the control room contains a control system that can be used to control the operation of the tracked chassis 131, the platform slewing mechanism 132, the lifting and angle adjustment system 14, the detection equipment 10, and the drilling rig 11.

[0069] For example, the four corners of the carrying platform 133 are also provided with liftable hydraulic outriggers 134. When the walking system 13 moves to the vicinity of the pre-drilling point, the hydraulic outriggers 134 are controlled to extend so that the lower end of the hydraulic outriggers 134 is supported on the ground, transferring the load of the entire machine from the tracked chassis 131 to the hydraulic outriggers 134. This avoids long-term load on the tracked chassis 131 during drilling, which could cause track deformation and improve the service life of the tracks.

[0070] In some embodiments, see Figure 1The lifting and angle adjustment system 14 includes a robotic arm 141, a lifting cylinder 142, and a swing cylinder 143. The lower end of the robotic arm 141 is hinged to the support platform 133 of the walking system 13, and the upper end of the robotic arm 141 is hinged to the bottom of the drilling platform 15. The lifting cylinder 142 is hinged between the robotic arm 141 and the support platform 133 of the walking system 13 and is used to drive the robotic arm 141 to rotate up and down in the vertical plane. The swing cylinder 143 is hinged between the robotic arm 141 and the drilling platform 15 and is used to drive the drilling platform 15 to swing up and down in the vertical plane. Both the lifting cylinder 142 and the swing cylinder 143 are pneumatic or hydraulic cylinders.

[0071] In use, the lifting cylinder 142 drives the robotic arm 141 to pitch as a whole, achieving a large-scale lifting and lowering of the drilling platform 15; the swing cylinder 143 then performs a secondary pitch fine-tuning of the drilling platform 15, achieving fine-tuning of the angle between the drilling platform 15 and the horizontal plane; the two complement each other to form a two-stage angle adjustment of coarse adjustment + fine adjustment, so that the height and angle of the drilling platform 15 meet the drilling requirements. For example, the robotic arm 141 can also be a telescopic arm with two or more stages. After extension, the telescopic arm can cover a larger elevation difference hole position, improving the applicability of the entire drilling and surveying integrated platform.

[0072] In some embodiments, see Figure 1 , Figure 4 The walking system 13 is equipped with a drill pipe storage basket 27. Specifically, the drill pipe storage basket 27 is a rectangular steel frame with an open top. The drill pipe storage basket 27 is placed on the support platform 133 and fixed by bolts and other fasteners. The drill pipe storage basket 27 contains several drill pipes.

[0073] Correspondingly, by setting up the drill rod storage basket 27, the drill rod 12 can be placed in the drill rod storage basket 27 so that the drill rod 12 can be moved with the walking system 13, saving manual handling; when the entire drilling and surveying integrated platform moves to the vicinity of the pre-drilling point, the drill rod 12 can be taken out for operation, reducing waiting time.

[0074] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
