DETAILED DESCRIPTION

[0030] With the development of the national economy and the acceleration of tunnel construction, the shield method has become widely used due to its cost-effectiveness. The shield method is a fully mechanized construction method. It involves pushing a shield machine underground, using the shield casing and segments to support the surrounding rock to prevent collapse into the tunnel. Simultaneously, a cutting device excavates soil in front of the excavation face. The soil is then transported out of the tunnel by excavation machinery, where it is pressurized and pushed forward by jacks at the rear. Precast concrete segments are then assembled to form the tunnel structure.

[0031] A shield machine is a specialized engineering machine used for tunneling, capable of excavating and cutting soil, transporting soil debris, assembling tunnel linings, and performing measurement, guidance, and deviation correction. Using a shield machine for tunnel construction offers advantages such as high automation, labor savings, and rapid construction. Shield machines are particularly economical and reasonable for long tunnels with deep burial depths.

[0032] During tunnel construction, complex strata may be encountered, such as fractured zones, karst caves, and water gushing. Advance drilling rigs can be used to survey the geological conditions ahead of the shield machine. For example, they can perform advance grouting reinforcement and improvement treatments ahead to avoid problems such as shield tunneling overruns. However, due to their large size and weight, advance drilling rigs typically require limited installation space within the shield machine and can easily interfere with other mechanical structures. This often requires frequent disassembly and assembly, impacting construction progress and increasing construction costs.

[0033] Based on the above technical problems, the embodiment of the present application provides an advance drilling rig equipment and a shield machine, wherein the advance drilling rig equipment includes a support assembly, a drive assembly, a slewing assembly and an advance drilling rig. In this way, the support assembly is beneficial to supporting the advance drilling rig equipment, thereby helping to ensure the normal operation of the above components; the drive assembly can adjust the movement direction and height of the advance drilling rig during operation, making the advance drilling rig more flexible and achieving multi-degree-of-freedom high-precision hole alignment and positioning adjustment of the advance drilling rig; the slewing assembly can achieve the folding of the advance drilling rig, which is convenient for the storage of the advance drilling rig and avoids structural interference, thereby improving the installation flexibility and eliminating the need for frequent disassembly during use, thereby improving the adaptability of the advance drilling rig in the shield tunnel, ensuring construction progress, and reducing construction costs.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] 1 and 2 , an embodiment of the present application provides a shield machine 200 for use in a tunnel to construct tunnel strata. The shield machine 200 includes at least a cutterhead 210 and a shield body 220 . "At least including" means that, in addition to the cutterhead 210 and shield body 220 , the shield machine 200 may also include other structures such as a slag discharge device, a screw conveyor, and a rear trailer, which are not elaborated upon in this embodiment of the present application.

[0036] The shield body 220 comprises a front shield, a middle shield, and a tail shield, with the middle shield connected between the front and tail shields. Specifically, the front shield is located on the side of the shield machine 200 closer to the tunneling end, while the tail shield is located on the side farther from the tunneling end (also known as the excavation end), located at the very front of the shield machine 200. The cutterhead 210 is connected to the front shield and is located at the tunneling end of the shield machine 200. It is used to excavate the tunnel strata.

[0037] As shown in Figure 1, the shield body 220 is provided with a connecting bridge 230, a segment assembly machine 240, and an advance drilling rig 100. The advance drilling rig 100 is connected between the connecting bridge 230 and the segment assembly machine 240. The connecting bridge 230 is an important component that connects the shield body 220 and the tail section. On the one hand, the connecting bridge 230 assumes the function of force transmission between the shield body 220 and the tail section. The propulsion force and torque on the shield body 220 can be transmitted to the tail section, driving the rotation and advancement of the cutterhead 210. On the other hand, the connecting bridge 230 plays a supporting and stabilizing role during the operation of the shield machine 200. By connecting to the support structure on the ground, the shield machine 200 maintains balance and stability during the excavation process, preventing tilting and deviation from the track.

[0038] For example, the advance drilling rig equipment 100 and the connecting bridge 230 can be fixed by a flange, and the front end of the advance drilling rig equipment 100 and the support beam of the segment assembly machine 240 can be connected by a pin shaft, which is not limited in this embodiment.

[0039] The structure of the advance drilling equipment according to the embodiment of the present application will be described below with reference to FIG3 to FIG10 .

[0040] This embodiment provides an advance drilling rig device 100 , which may include a support assembly 110 , at least one drive assembly 120 , at least one slewing assembly 130 , and at least one advance drilling rig 140 .

[0041] In some embodiments, the number of the driving assemblies 120 may include one, two, or more, the number of the slewing assemblies 130 may include one, two, or more, and the number of the advanced drilling rigs 140 may include one, two, or more. This embodiment does not limit this.

[0042] The drive assembly 120 is connected to the support assembly 110 , the slewing assembly 130 is connected to the free end of the drive assembly 120 , and the advance drill rig 140 is connected to the free end of the slewing assembly 130 . The drive assembly 120 , the slewing assembly 130 and the advance drill rig 140 are located on the same side of the support assembly 110 .

[0043] Among them, the support assembly 110 serves as a basic bearing component, which can support the advance drilling rig equipment 100, thereby helping to ensure the normal operation of the above components. In addition, the drive assembly 120, the rotary assembly 130 and the advance drilling rig 140 are located on the same side of the support assembly 110, which makes it easier to drive the advance drilling rig 140.

[0044] The drive assembly 120 is used to drive the advance drill 140 in a preset direction. For example, the preset direction may be: the drive assembly 120 drives the advance drill 140 in a vertical direction to adjust the vertical height between the advance drill 140 and the drill hole in the shield wall; or the drive assembly 120 drives the advance drill 140 in a horizontal direction to adjust the horizontal distance between the advance drill 140 and the drill hole. This provides the advance drill 140 with greater freedom of movement, thereby helping to ensure high-precision hole alignment and positioning adjustment of the advance drill 140. It should be noted that the preset direction is not limited and the advance drill 140 can be adjusted according to actual needs.

[0045] Among them, there is no limitation on the driving mode of the driving component 120. For example, the advance drilling rig equipment 100 can be installed with a radio remote control. In this way, the advance drilling rig 140 is driven to move by wireless remote control, which has higher operation convenience and higher control accuracy, further ensuring the high-precision hole alignment and positioning adjustment of the advance drilling rig 140, which helps to ensure the construction progress and shorten the construction time.

[0046] In some embodiments, there is no limitation on the connection method between the drive assembly 120 and the support assembly 110. For example, the drive assembly 120 and the support assembly 110 can be connected by a snap connection, a threaded connection, etc., or the drive assembly 120 and the support assembly 110 can be slidably connected, which is not limited in this embodiment.

[0047] In some embodiments, the rotary assembly 130 is connected to the free end of the drive assembly 120, wherein the free end of the drive assembly 120 is the end of the drive assembly 120 that is not connected to the support assembly 110. For example, the drive assembly 120 and the support assembly 110 can be connected by a snap connection, a threaded connection, etc., or the drive assembly 120 and the support assembly 110 can be connected by welding, which is not limited in this embodiment.

[0048] In some embodiments, the advance drill 140 is connected to the free end of the slewing assembly 130, where the free end of the slewing assembly 130 is the end of the slewing assembly 130 that is not connected to the drive assembly 120. For example, the advance drill 140 and the slewing assembly 130 may be connected by a snap connection, a threaded connection, or may be connected by welding, which is not limited in this embodiment.

[0049] The slewing assembly 130 is used to drive the advance drilling rig 140 to deflect in a first direction when the advance drilling rig equipment 100 is in a first state, thereby forming a working state of the advance drilling rig 140. For example, the first state of the advance drilling rig equipment 100 may be: when encountering various complex strata, such as fracture zones, karst caves, water gushing, and other unfavorable geological conditions, the advance drilling rig equipment 100 detects the geological conditions ahead of the shield machine. At this time, the slewing assembly 130 drives the advance drilling rig 140 to deflect in the first direction, wherein the deflection direction of the first direction can be shown by the direction of arrow A1 in FIG. 4 . The working state of the advance drilling rig 140 after deflection can be shown in the positions in FIG. 3 to FIG. 6 , so that the advance drilling rig 140 performs advance grouting in the front for reinforcement and improvement.

[0050] The slewing assembly 130 is further configured to drive the lead drilling rig 140 to slew in a second direction when the lead drilling rig 100 is in the second state, thereby forming a folded storage state for the lead drilling rig 140. For example, the second state of the lead drilling rig 100 may be: when no complex strata, such as fractured zones, karst caves, or other unfavorable geological conditions, are encountered, the lead drilling rig 100 is in a standby state, and at this time, the slewing assembly 130 drives the lead drilling rig 140 to slew in the second direction. The second direction of rotation can be shown by the arrow A2 in FIG. 4 . The folded storage state of the lead drilling rig 140 after rotation can be shown in the positions in FIG. 7 and FIG. 8 .

[0051] It should be noted that the first direction and the second direction are different directions.

[0052] Therefore, the advance drilling rig equipment 100 provided in the present application includes a slewing assembly 130 and an advance drilling rig 140. The slewing assembly 130 can control the rotation direction and speed of the advance drilling rig 140. The slewing assembly 130 can realize the folding of the advance drilling rig 140, which is convenient for the storage of the advance drilling rig 140 and avoids structural interference, thereby improving the installation flexibility and eliminating the need for frequent disassembly during use, thereby improving the adaptability of the advance drilling rig 140 in the shield tunnel, ensuring construction progress, and reducing construction costs.

[0053] In a possible implementation, the slewing assembly 130 may include a slewing motor, a reducer, and a slewing bearing. The reducer is connected to the slewing motor and the slewing bearing, respectively. The advance drilling rig 140 is connected to the slewing bearing.

[0054] The rotation principle of the slewing assembly 130 of the present application is as follows: the working principle of the slewing assembly 130 is realized through a hydraulic system. First, the hydraulic pump draws the hydraulic oil from the tank and transmits it to the slewing motor through the hydraulic pipeline to generate a rotational force. The slewing motor converts the kinetic energy of the hydraulic oil into mechanical energy, and converts the input hydraulic energy into a rotational torque through the internal gear device and transmits it to the reducer. The reducer is used to receive the rotational torque and realize speed reduction through the relative rotation of the gears. The reducer is also used to output the decelerated rotational torque to the slewing bearing. The slewing bearing is a key component supporting the slewing assembly 130. It can bear the weight of the fuselage and external loads, and drive the advance drill rig 140 to move in the first direction or the second direction by rolling or sliding, thereby realizing the rotation of the advance drill rig 140.

[0055] It should be noted that during the entire rotation process, the hydraulic pump, the rotation motor and the hydraulic pipeline jointly process the liquid system of the rotation component 130. By controlling the flow speed and direction of the hydraulic oil in the hydraulic system, the rotation component 130 can be controlled and adjusted.

[0056] In one possible implementation, as shown in Figures 3 to 8 , there may be two drive assemblies 120, each of which is connected to the support assembly 110. There may also be two swivel assemblies 130, each of which is connected to the free ends of the two drive assemblies 120 in a one-to-one correspondence.

[0057] The number of lead drills 140 can include two, and the two lead drills 140 are connected to the free ends of the two rotary assemblies 130 in a one-to-one correspondence. When the lead drill apparatus 100 is in the second state, the two rotary assemblies 130 correspondingly drive the two lead drills 140 to rotate in the second direction, and the rotation directions of the two lead drills 140 are opposite to each other.

[0058] For example, as shown in FIG4 , when the lead drilling rig 100 is in the second state, one swivel assembly 130 drives the lead drilling rig 140 to rotate in the direction of one arrow A2 in FIG4 , while the other swivel assembly 130 drives the lead drilling rig 140 to rotate in the direction of the other arrow A2 in FIG4 . The two lead drilling rigs 140 rotate in opposite directions. This arrangement ensures that the two lead drilling rigs 140 can be folded and stored without interfering with each other, and can automatically avoid each other.

[0059] It should be noted that there is no limit on the number of the above-mentioned structural parts. For example, the number of drive assemblies 120 may include multiple, and the multiple drive assemblies 120 are respectively connected to the support assembly 110. The number of rotary assemblies 130 may include multiple, and the multiple rotary assemblies 130 are connected to the free ends of the multiple drive assemblies 120 in a one-to-one correspondence. The number of advance drilling rigs 140 may include multiple, and the multiple advance drilling rigs 140 are connected to the free ends of the multiple rotary assemblies 130 in a one-to-one correspondence. In this way, by using multiple advance drilling rigs 140, when performing advance grouting reinforcement and improvement treatment on the front, it is beneficial to improve the grouting effect and further avoid the occurrence of problems such as shield tunneling over-discharge.

[0060] In one possible implementation, as shown in Figure 4, the driving assembly 120 may include a crawling trolley mechanism 121 and a lifting mechanism 122, the crawling trolley mechanism 121 is connected to the support assembly 110, the lifting mechanism 122 is connected to the side of the crawling trolley mechanism 121 close to the rotating assembly 130, and the rotating assembly 130 is connected to the lifting mechanism 122.

[0061] In some embodiments, the crawler mechanism 121 crawls on the support assembly 110. For example, the crawler mechanism 121 can crawl 360° on the support assembly 110. This facilitates driving the lead drill 140 to rotate 360°, enabling azimuth adjustment of the lead drill 140. In some embodiments, the lifting mechanism 122 can be a lifting cylinder. The extension and retraction of the lifting cylinder allows the lifting mechanism 122 to be adjusted in height, thereby adjusting the height of the lead drill 140.

[0062] For example, as shown in FIG9 , the telescopic length of the lifting cylinder is different, and the lifting height of the lifting mechanism 122 is also different. The lifting height of the lifting mechanism 122 can be shown as the distance h in FIG9 .

[0063] In one possible implementation, as shown in FIG9 , the crawling trolley mechanism 121 may include a trolley body 1211 and a drive motor 1212. The drive motor 1212 is connected to the trolley body 1211 and is configured to drive the trolley body 1211 to rotate along the circumferential direction of the support assembly 110. Specifically, the drive motor 1212 drives the trolley body 1211 to crawl 360° on the support assembly 110.

[0064] It should be noted that the drive motor 1212 is a device that converts electrical energy into mechanical motion energy. The working principle of the drive motor 1212 is based on the principle of magnetodynamics. The drive motor 1212 converts electrical energy into mechanical energy by generating a rotational torque through the interaction between the electric field and the magnetic field, thereby driving the trolley body 1211 to move.

[0065] In a possible implementation, as shown in FIG9 , the crawling trolley mechanism 121 may further include a self-aligning roller 1213 connected to the trolley body 1211. The self-aligning roller 1213 is used to adjust the gap between the trolley body 1211 and the support assembly 110. This arrangement allows for an appropriate gap to be maintained between the trolley body 1211 and the support assembly 110. On the one hand, this helps avoid the problem of the trolley body 1211 not being stable when the gap between the trolley body 1211 and the support assembly 110 is too large. On the other hand, this helps avoid the problem of the trolley body 1211 being easily stuck and difficult to crawl when the gap between the trolley body 1211 and the support assembly 110 is too small. In addition, it helps avoid the trolley body 1211 being stuck on the support assembly 110.

[0066] In some embodiments, there is no limitation on the connection method between the aligning rollers 1213 and the trolley body 1211. For example, the aligning rollers 1213 and the trolley body 1211 can be connected by means of a snap connection, a threaded connection, or welding. In some embodiments, there is no limitation on the number of aligning rollers 1213 provided, and they can be arranged according to actual needs.

[0067] 9 , the crawling trolley mechanism 121 may further include side guard wheels 1214 connected to the outer periphery of the trolley body 1211. The side guard wheels 1214 are used to prevent the trolley body 1211 from sliding off the support assembly 110. This arrangement helps prevent the trolley body 1211 from falling off the support assembly 110 during the crawling process, further improves the installation stability of the trolley body 1211, and thus ensures smooth movement of the lead drill rig 140.

[0068] In some embodiments, there is no limit on the number of side wheels 1214. For example, the number of side wheels 1214 can be set to one, and one side wheel 1214 is set on the periphery of the trolley main body 1211; the number of side wheels 1214 can be set to two, and two side wheels 1214 are set at intervals on the periphery of the trolley main body 1211; the number of side wheels 1214 can be set to multiple, and multiple side wheels 1214 are set at intervals along the periphery of the trolley main body 1211, so as to maximize the limiting effect on the trolley main body 1211.

[0069] In one possible implementation, as shown in Figures 3 and 4 , the support assembly 110 may include a support platform 111 and an annular support member 112. The annular support member 112 is slidably connected to the support platform 111 and reciprocates along the axial direction of the support platform 111. The crawler mechanism 121 is connected to the annular support member 112 and rotates along the circumferential direction of the annular support member 112. For example, the support platform 111 in this embodiment may be an independent track, and the annular support member 112 may be an annular beam.

[0070] In some embodiments, the annular beam has a large gear ring, the crawling trolley mechanism 121 has gears, and the trolley body 1211 crawls on the large gear ring through the gears and the drive motor 1212, thereby realizing the crawling of the crawling trolley mechanism 121 on the annular beam.

[0071] In some embodiments, the annular support member 112 is slidably connected to the support platform 111, and the annular support member 112 slides back and forth along the axial direction of the support platform 111. This helps to drive the advance drill rig 140 to reciprocate along the axial direction, thereby achieving azimuth adjustment of the advance drill rig 140.

[0072] There is no limitation on the sliding connection method between the annular support member 112 and the support platform 111. For example, a slide rail may be provided on one of the annular support member 112 and the support platform 111, and a slider may be provided on the other of the annular support member 112 and the support platform 111. The slide rail slides in the slide rail to achieve sliding connection between the annular support member 112 and the support platform 111.

[0073] In one possible implementation, a translation cylinder may be connected between the support platform 111 and the annular support member 112, which can drive the annular support member 112 to slide back and forth on the support platform 111. In some embodiments, as shown in FIG3 , a running mechanism 1121 may be provided at the bottom of the annular support member 112, and the annular support member 112 slides on the support platform 111 via the running mechanism 1121. For example, the running mechanism 1121 may be a running wheel.

[0074] In one possible implementation, as shown in FIG4 , a pitch cylinder 150 may be connected between the advance drilling rig 140 and the slewing assembly 130. The pitch cylinder 150 is used to control and adjust the pitch angle of the advance drilling rig 140. Specifically, the pitch angle of the advance drilling rig 140 is adjusted by the pitch cylinder 150, which helps meet the requirements of the advance drilling rig 140 for advanced drilling and grouting in both inclined and horizontal directions.

[0075] In some embodiments, as shown in FIG3 and FIG10 , a work platform 160 may be provided on the advance drilling rig 100. An operator may stand on the work platform 160 when performing work such as disassembling or repairing the advance drilling rig 100. For example, the work platform 160 may be connected to the support platform 111, but this embodiment is not limited thereto.

[0076] The embodiment of the present application provides an advance drilling rig device 100 and a shield machine 200. The advance drilling rig device 100 includes a support assembly 110, a drive assembly 120, a slewing assembly 130, and an advance drilling rig 140. Thus, the support assembly 110 is beneficial for supporting the advance drilling rig device 100, thereby helping to ensure the normal operation of the above components; the drive assembly 120 can adjust the movement direction and height of the advance drilling rig 140 during operation, making the advance drilling rig 140 more flexible and enabling multi-degree-of-freedom, high-precision hole alignment and positioning adjustment of the advance drilling rig 140; the slewing assembly 130 can fold the advance drilling rig 140, facilitating storage of the advance drilling rig 140 and avoiding structural interference, thereby improving installation flexibility and eliminating the need for frequent disassembly during use. This improves the adaptability of the advance drilling rig 140 in shield tunnels, ensures construction progress, and reduces construction costs.
