Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction technical field, especially relate to a structure combination of can realize drilling arch digs. BACKGROUND

[0002] The tunneling machine and the arch anchor trolley are used to complete the tunneling, arch erecting and anchor rod construction separately. The tunneling machine mainly comprises a traveling mechanism, a working mechanism, a loading mechanism and a transfer mechanism. The cutting head or the breaking hammer in the working mechanism breaks the rock continuously as the traveling mechanism advances, and the broken slag and broken stone are transferred out through the corresponding transfer device. The arch erecting and anchor rod construction mainly rely on the independent movement of the arms of the arch anchor trolley, and the arms are cooperated to complete the installation of the arch. After the installation of the arch is completed, the anchor rod construction is performed by the rock drilling device beside the arms.

[0003] Because the tunneling machine and the arch anchor trolley have large volumes and wide working radii, the conventional tunneling, arch erecting and anchor rod construction are basically performed separately to meet the requirements of the working site. This step-by-step construction method wastes a lot of time due to the transfer of vehicles in the connection process of the tunneling, arch erecting and anchor rod construction. Moreover, this step-by-step construction method is inefficient, and the time required is the sum of the time of the two construction methods. SUMMARY

[0007] A first translation mechanism and a second translation mechanism are arranged between the tunneling mechanism and the rack, and the tunneling mechanism is hinged to the second translation mechanism. The first translation mechanism comprises a sliding beam slidably arranged in the rack. A propelling mechanism is arranged in the rack to drive the sliding beam to slide. The second translation mechanism is arranged on the sliding beam and is used to drive the tunneling mechanism to move left and right.

[0008] Based on the above-mentioned structural combination that enables drilling and arch excavation, a first swing mechanism is provided between the second translation mechanism and the tunneling mechanism. The first swing mechanism is used to drive the tunneling mechanism to swing up and down.

[0009] Based on the above-mentioned structural combination that enables drilling and arch excavation, the tunneling mechanism includes a second swing mechanism hinged to the second translation mechanism.

The rock drilling mechanism is mounted on the first rotating seat through a mounting mechanism. The first rotary reducer can drive the first rotating seat to rotate around the telescopic arm. The first rotating seat has a cavity through which the movable arm passes.

The second rotary reducer is connected between the first rotary seat and the second rotary seat, and the third rotary reducer is connected between the second rotary seat and the rock drilling mechanism.

[0014] The second rotary reducer is used to drive the second rotary seat and the rock drilling mechanism to rotate around the first rotary seat, and the third rotary reducer is used to drive the rock drilling mechanism to rotate around the second rotary seat; the rotation axes of the first rotary reducer, the second rotary reducer and the third rotary reducer are perpendicular to each other.

[0015] Based on the above-mentioned structural combination that enables drilling and arch excavation, a slag discharge mechanism is provided in the slag discharge channel. The slag discharge mechanism includes an auxiliary excavator arm and a material conveying system located at the front end of the platform. The transport vehicle moves to the end of the material conveying system, and the auxiliary excavator arm pushes the slag generated during excavation to the front end of the material conveying system. The material conveying system automatically transports the slag to the transport vehicle, which then moves it out of the tunnel.

[0016] Based on the above-mentioned structural combination that enables drilling and arch excavation, the material conveying system discharges slag from the bottom of the platform; or discharges slag from at least one side of the platform; or first discharges slag from the bottom of the platform, and then discharges slag through the platform from at least one side of the platform.

[0017] This solution also discloses another structural combination that can realize arch drilling, including a platform, an arch drilling arm mechanism and a tunneling mechanism; the arch drilling arm mechanism is slidably mounted on at least one side of the platform, the tunneling mechanism is located at the front end of the platform, and the arch drilling arm mechanism is provided with an arch section for arch erection and a drilling section for drilling.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0024] 1. The technical problem this solution aims to solve is that the tunneling, arch erection, and anchor bolting equipment cannot operate simultaneously due to interference, resulting in construction delays and low efficiency. The interference occurs because the anchor bolting trolley typically needs to be parked in front of the tunnel face, while the tunneling machine needs to move within a certain range in front of the tunnel face. During the tunneling machine's movement, interference occurs between the machine and the stationary anchor bolting trolley. This solution integrates the tunneling machine's boom and the anchor bolting trolley's drilling boom into a single device. Through the combined operation of the tunneling boom, which can slide forward, backward, left, and right at the front of the trolley, and the anchor bolting mechanism, which can slide and extend on both sides of the trolley, the solution achieves the functional effect of parallel tunneling, arch erection, and anchor bolting operations.

[0025] 2. Because the drilling arm mechanism is slidably mounted on the side of the platform, it facilitates arch erection and anchor bolt construction, overcoming the problem of interference between the working areas of tunneling, arch erection, and anchor bolting. This allows for parallel operations, saving equipment relocation time and improving work efficiency. Previously, the time required to complete the two processes was the sum of the two; now it becomes the longer of the two processes, significantly accelerating the construction process.

[0026] 3. This solution integrates multiple functions such as excavation, frame erection, and anchor bolting into a single trolley. It can be used in conjunction with a muck loader or dump truck to remove slag, completing all construction processes at the tunnel face. This enables parallel or seamless connection of processes, changing the traditional methods of independent and non-parallel operations and multi-machine cooperation, significantly improving construction progress and creating more value for customers.

[0027] 4. The platform in this solution integrates functions such as tunneling and excavation, arch frame installation, and anchor bolt construction. By using different components for different construction operations, it replaces frequently changed equipment, thereby saving time on equipment movement in and out of the tunnel. Furthermore, by performing multiple parallel operations such as muck removal during excavation and arch frame loading during anchor bolt construction, it further shortens the cycle time of each operation, improving construction efficiency and reducing safety hazards.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a predetermined orientation, or be constructed and operated in a predetermined orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0046] Example 1

[0047] like Figures 1-9 As shown, this utility model provides a technical solution:

[0048] A structural assembly capable of drilling and arch excavation includes, but is not limited to, a platform 100, a drilling and arch arm mechanism 101, and a tunneling mechanism 200; the drilling and arch arm mechanism 101 is slidably mounted on at least one side of the platform 100, the tunneling mechanism 200 is located below the platform 100, and the drilling and arch arm mechanism 101 is provided with a cooperating part for transporting the arch frame and a drilling part for drilling operations.

[0049] Based on the above structure, in this scheme, the platform 100 serves as the main support for the entire structure. Its design facilitates the setting of the lower muck discharge channel, ensuring that muck discharge vehicles or equipment can pass smoothly. The drilling arch arm mechanism 101 and the tunneling mechanism 200 are respectively set on the side and below the platform 100, which is a structural combination that can realize drilling, arching, and tunneling. This can avoid mutual interference between the two during the sliding process. At the same time, the tunneling mechanism 200 and the arch anchor component are integrated on one platform 100, which can carry out parallel construction. When the drilling arch arm mechanism 101 is performing arch erection or anchor bolt operation, the tunneling mechanism 200 can simultaneously carry out the next cycle of excavation operation without the need for the transfer time of independent devices. This can greatly improve work efficiency and save construction time.

[0050] Under normal circumstances, drilling operations include drilling for system anchor bolts, drilling for locking foot anchor bolts, and drilling for advance anchor bolts. However, when encountering hard rock, the high-frequency breaker in the tunneling section cannot break it. In this case, it is necessary to use the drilling arch and / or rock drilling section to drill blast holes. Since the drilling operation of the drilling arch and rock drilling section is rotary and its drilling components are relatively small, it can drill for hard rock, which facilitates subsequent micro-blasting operations. After the rock is blasted, tunneling operations can then be carried out.

[0051] As an example, a drive assembly is provided on the platform 100, which is used to drive the tunneling mechanism 200 to perform working movements; wherein, the working movements include up-and-down swinging and left-and-right movement.

[0052] In this embodiment, by directly integrating the tunneling mechanism 200 onto the platform 100, and using the drive component to drive the tunneling mechanism 200 to perform up-and-down swinging and left-and-right movement, the tunneling mechanism 200 has multi-degree-of-freedom movement function. While the platform 100 remains stationary, the range of movement of the tunneling mechanism 200 for excavation operations can be guaranteed. Therefore, it can replace the tunneling machine for operation, reducing the cost of the entire unit and improving construction efficiency.

[0053] As an optional implementation, the drive assembly includes a second translation mechanism 400, the tunneling mechanism 200 is hinged to the second translation mechanism 400, and a first swing mechanism 500 is provided between the second translation mechanism 400 and the tunneling mechanism 200. The first swing mechanism 500 is used to drive the tunneling mechanism 200 to swing up and down, and the second translation mechanism 400 is used to drive the tunneling mechanism 200 to move left and right.

[0054] In this embodiment, when excavating in the tunnel, the first swing mechanism 500 can drive the tunneling mechanism 200 to swing up and down, thereby achieving excavation in the vertical direction. The second translation mechanism 400 can drive the tunneling mechanism 200 to move left and right, thereby achieving excavation in the horizontal direction. Through the coordinated operation of the second translation mechanism 400 and the first swing mechanism 500, the tunneling mechanism 200 can perform various working movements individually or simultaneously, thus meeting the excavation requirements of complex movements.

[0055] As an optional implementation, the drive assembly also includes a first translation mechanism 300 disposed within the platform 100. The first translation mechanism 300 is used to drive the second translation mechanism 400 and the tunneling mechanism 200 to move back and forth as a whole. The first translation mechanism 300 includes a sliding beam 310 slidably disposed within the platform 100. A propulsion mechanism 320 is disposed within the platform 100 to drive the sliding beam 310 to slide. The second translation mechanism 400 is disposed on the sliding beam 310.

[0056] In this embodiment, the first translation mechanism 300 can drive the second translation mechanism 400 and the tunneling mechanism 200 to move back and forth as a whole, thereby realizing the feeding and excavation of the tunnel. When excavation is not required, the tunneling mechanism 200 can be retracted into the platform 100 to make room for other mechanical parts to work. When the tunneling mechanism 200 needs to move forward or backward, the propulsion mechanism 320 drives the sliding beam 310 to move forward or backward within the platform 100, which in turn drives the second translation mechanism 400 on the sliding beam 310 to move forward or backward synchronously with the tunneling mechanism 200, realizing the automatic operation of feeding or retracting the tunneling mechanism 200. Therefore, through the coordinated cooperation of the first translation mechanism 300, the second translation mechanism 400, and the first swing mechanism 500, the excavation needs of more complex actions can be met, further improving the adaptability.

[0057] It should be noted that the propulsion mechanism 320 can adopt a telescopic hydraulic cylinder, sprocket drive, or gear drive structure, as long as it can drive the sliding beam 310 to move linearly; there should be no restriction here. The aforementioned forward and backward movement is parallel to the tunnel excavation direction, while the left and right movement is perpendicular to the forward and backward movement in the horizontal direction.

[0058] As an optional implementation, the two inner side walls of the platform 100 are provided with slide rails 330, and the sliding beam 310 is slidably disposed between the two slide rails 330. The slide rails 330 guide the sliding beam 310 to slide, resulting in low wear and stable operation.

[0059] As an optional implementation, the second translation mechanism 400 includes a transverse seat 410 slidably disposed on the sliding beam 310, the tunneling mechanism 200 is hinged to the transverse seat 410, and a transverse mechanism 420 is disposed on the side end of the sliding beam 310. The transverse mechanism 420 is used to drive the transverse seat 410 to slide along the sliding beam 310.

[0060] In this embodiment, when it is necessary to move the tunneling mechanism 200 left or right to adjust the excavation width position, the transverse mechanism 420 drives the transverse seat 410 to slide left or right on the sliding beam 310, thereby causing the tunneling mechanism 200 on the transverse seat 410 to move synchronously and realize automatic left and right movement operation.

[0061] It should be noted that the transverse sliding seat 410 can be slidably connected to the side end of the sliding beam 310 via a sliding assembly, or the transverse sliding seat 410 can be a frame structure, thus slidingly fitted onto the sliding beam 310, making it difficult to detach and ensuring structural stability and reliability. Similarly, the transverse sliding mechanism 420 can adopt a telescopic hydraulic cylinder, sprocket drive, or gear drive structure.

[0062] As an optional implementation, the tunneling mechanism 200 includes a second swing mechanism 210 hinged to the second translation mechanism 400. The second swing mechanism 210 is hinged to the tunneling arm 220 and is used to drive the tunneling arm 220 to swing left and right.

[0063] In this embodiment, the tunneling mechanism 200 performs rock drilling operations via the tunneling arm 220, and also has a built-in second swing mechanism 210 that can drive the tunneling arm 220 to swing left and right, thereby adapting to a certain width of excavation range. There is no need to frequently operate the second translation mechanism 400 to drive the tunneling arm 220 to move left and right. Therefore, the tunneling arm 220 can be moved significantly in the tunnel width direction by the second translation mechanism 400, while the tunneling arm 220 can be moved slightly in the tunnel width direction by the second swing mechanism 210. This reasonable and effective coordination can improve construction efficiency.

[0064] As an optional implementation, the second swing mechanism 210 includes a connecting frame 211 hinged to the second translation mechanism 400, a tunneling arm 220 disposed on the connecting frame 211, and swing cylinders 212 hinged to both sides of the connecting frame 211, with the other end of the swing cylinders 212 hinged to the second translation mechanism 400.

[0065] In this embodiment, when the tunneling arm 220 needs to swing left and right, one swing cylinder 212 extends and the other swing cylinder 212 shortens accordingly, thereby driving the connecting frame 211 and the tunneling arm 220 to rotate to one side. When it is necessary to rotate to the other side, the two swing cylinders 212 can be extended and retracted in opposite directions, thereby realizing the swing control of the tunneling arm 220 to switch the rock drilling position.

[0066] It should be noted that the connecting bracket 211 should be hinged to the side of the transverse sliding seat 410, and the corresponding hinge structure should only support horizontal rotation.

[0067] As an optional implementation, the tunneling arm 220 includes a first frame 221 hinged to a connecting frame 211, a second frame 222 hinged to the first frame 221, and a hydraulic breaker 223 hinged to the second frame 222. A first swing mechanism 500 is used to drive the first frame 221, the second frame 222, and the hydraulic breaker 223 to swing up and down. The hydraulic breaker 223 can be either a conventional piston-impact hydraulic breaker 223 or a high-frequency hydraulic breaker 223. Generally, unless the rock strata are too hard, the excavation efficiency of a high-frequency hydraulic breaker 223 is higher than that of a conventional piston-impact hydraulic breaker 223.

[0068] In this embodiment, the tunneling arm 220 can move in multiple joints through the first frame 221 and the second frame 222. With the driving action of the first swing mechanism 500, the breaker hammer 223 can accurately perform rock drilling operations at the excavation location.

[0069] As an optional implementation, the first swing mechanism 500 includes a first cylinder 510 hinged between the connecting frame 211 and the first frame 221, a second cylinder 520 hinged between the first frame 221 and the second frame 222, and a third cylinder 530 hinged between the second frame 222 and the breaker hammer 223.

[0070] In this embodiment, the first hydraulic cylinder 510 can control the first frame 221 to swing up and down, the second hydraulic cylinder 520 can control the second frame 222 to swing up and down, and the third hydraulic cylinder 530 can control the breaker hammer 223 to swing up and down, thereby making graded and gradual adjustments to achieve flexible movement of the entire tunneling arm 220.

[0071] As an optional implementation, the platform 100 includes a platform 110, with two support frames 120 disposed at the bottom of the platform 110, and a drive assembly disposed between the two support frames 120. A working space is formed between the platform 110 and the two support frames 120, which can be used for other construction operations, thereby facilitating the simultaneous execution of multiple tasks and improving work efficiency.

[0072] As an example, the drilling arm mechanism 101 includes a guide rail 1, a sliding trolley 2, a telescopic arm 3, a swing arm 4, a gripper mounting part 5, a gripper assembly 6, and a rock drilling mechanism 7. In this embodiment, the gripper assembly 6 is used to grip the side arch frame.

[0073] The sliding trolley 2 is slidably mounted on the guide rail 1. A hydraulic motor 21 is installed on the sliding trolley 2, and rollers are located at its bottom. The rollers roll in contact with the guide rail 1. The hydraulic motor 21 drives the rollers to rotate via a chain, thereby driving the sliding trolley 2 to move on the guide rail 1. A hydraulic station 22 is also installed on the sliding trolley 2 to provide hydraulic power to the entire drilling arm mechanism 101.

[0074] Optionally, a rotary table 23 is rotatably mounted on the sliding trolley 2, and a telescopic arm 3 is hinged to the rotary table 23, allowing the telescopic arm 3 to deflect up and down. A deflection cylinder 24 is provided between the sliding trolley 2 and the rotary table 23. The piston rod of the deflection cylinder 24 is hinged to the side wall of the rotary table 23. The extension and retraction of the piston rod of the deflection cylinder 24 can drive the rotary table 23 to rotate in the horizontal plane, thereby causing the entire telescopic arm 3 to deflect left and right.

[0075] The telescopic arm 3 is capable of extending or retracting. The telescopic arm 3 includes a fixed arm 31 and a movable arm 32. One end of the fixed arm 31 is hinged to the rotary table 23, and the movable arm 32 is slidably disposed within the fixed arm 31 along its length. A second drive source 33 for driving the movable arm 32 to slide is provided on the fixed arm 31. The second drive source 33 is a second hydraulic cylinder 520 mounted on the fixed arm 31, and the piston rod of the second hydraulic cylinder 520 is hinged to the movable arm 32. To ensure smooth movement of the movable arm 32, two second hydraulic cylinders 520 are provided.

[0076] A pitch cylinder 231 is provided between the rotary table 23 and the telescopic arm 3. Specifically, the piston rod of the pitch cylinder 231 is hinged to the bottom wall of the fixed arm 31. The pitch cylinder 231 can drive the fixed arm 31 to pitch up or down.

[0077] The movable end of the telescopic arm 3 is connected to a pitch adjustment seat 321. Specifically, the pitch adjustment seat 321 is located at the end of the movable arm 32 away from the fixed arm 31. The pitch adjustment seat 321 is a rod-shaped structure and is coaxial with the telescopic rod. A swing arm 4 is hinged to the end of the pitch adjustment seat 321 away from the telescopic rod.

[0078] Optionally, the drilling arm mechanism 101 further includes a first drive assembly connected to the swing arm 4 for driving the swing arm 4 to rotate within a first base plane. In this embodiment, the first base plane is a horizontal plane. The first drive assembly includes a first drive source 81, a first hinge shaft 82, a first connecting rod 83, and a second connecting rod 84. One end of the first connecting rod 83 is hinged to the swing arm 4, and the other end is hinged to the second connecting rod 84 via the first hinge shaft 82. The first hinge shaft 82 is vertically arranged and perpendicular to the telescopic rod. The end of the second connecting rod 84 away from the first connecting rod 83 is hinged to the swing arm 4. The first drive source 81 is used to drive the first hinge shaft 82 to deflect. In this embodiment, the first drive source 81 is a first hydraulic cylinder 510, and the piston rod of the first hydraulic cylinder 510 is hinged to the first hinge shaft 82. In other embodiments, the first drive source 81 may also be a first air cylinder. The first drive source 81 drives the first hinge shaft 82 to move, and the first hinge shaft 82 drives the first connecting rod 83 and the second connecting rod 84 to deflect, thereby achieving the purpose of driving the swing arm 4 to rotate.

[0079] A gripper mounting part 5 is hinged to one end of the swing arm 4 away from the telescopic rod. A second driving member 41 is provided on the swing arm 4 to drive the gripper mounting part 5 to rotate within a second base plane.

The second driving member 41 is a second hydraulic cylinder hinged to the swing arm 4, and the piston rod of the second hydraulic cylinder is hinged to the gripper mounting part 5.

[0080] Optionally, a gripper assembly 6 is disposed on the gripper mounting portion 5 for clamping the arch frame. The gripper assembly 6 includes a receiving plate 61 and a gripper. One end of the receiving plate 61 is hinged to the gripper mounting portion 5, and the gripper is disposed on the receiving plate 61 for clamping the arch frame.

[0082] Optionally, the drilling arm mechanism 101 also includes a suspended platform 9, which is mounted on the swing arm 4. The suspended platform 9 is detachably mounted on the side of the swing arm 4 away from the gripper assembly 6 via a pin 92. Specifically, two fixing blocks 42 are fixedly mounted on the side wall of the swing arm 4 at intervals, and ear plates 91 are fixedly mounted on the side wall of the suspended platform 9.

The ear plates 91 are inserted into the slots, and the pin 92 is inserted into the holes, passing through the fixing blocks 42 and ear plates 91 to achieve the installation and fixation of the suspended platform 9. By positioning the suspended platform 9 on the side of the swing arm 4 away from the gripper assembly 6, interference from the gripper assembly 6 is prevented during the installation or maintenance of the suspended platform 9, and installation, removal, and maintenance are convenient.

[0083] The rock drilling mechanism 7 is rotatably mounted at the end of the movable arm 32 away from the fixed arm 31. The rock drilling mechanism 7 enables rock drilling operations and, in conjunction with the gripper assembly 6, allows the arch drilling arm mechanism 101 to perform both rock drilling and arch erection operations, improving tunnel construction efficiency. The specific structure of the rock drilling mechanism 7 is existing technology and will not be described in detail here.

[0084] Optionally, a first rotating seat 101 is provided at the end of the movable arm 32 away from the fixed arm 31. The first rotating seat 101 has a cavity through which the movable arm 32 passes, and the size of the cavity is larger than the size of the movable arm 32 to prevent the movable arm 32 from interfering with the rotation of the first rotating seat 101. A first rotary reducer 102 is connected between the first rotating seat 101 and the movable arm 32. The rock drilling mechanism 7 is mounted on the first rotating seat 101 through a mounting mechanism. The first rotary reducer 102 can drive the first rotating seat 101 to rotate around the telescopic arm 3.

[0085] The mounting mechanism includes a second rotary seat 103, a second rotary reducer 104, and a third rotary reducer 105.

[0087] The first rotary reducer 102 drives the first rotating seat 101 to rotate, thereby driving the rock drilling mechanism 7 to rotate around the telescopic arm 3.

[0088] Of course, in some embodiments of the present invention, the drill arch can also be as shown in CN216894470U. Figure 2 and CN115434729A Figure 2 The structural form, CN216894470U and CN115434729A are both prior patent applications of the applicant. The drilling arch can use the previous structural components as an implementation of the multifunctional integrated unit of the present invention.

[0089] In this scheme, a slag discharge mechanism is set in the slag discharge channel. The slag discharge mechanism includes an auxiliary excavator arm 5000 set at the front end of the platform and a material conveying system 6000. When the transport vehicle moves to the end of the material conveying system, the auxiliary excavator arm pushes the slag generated during excavation to the front end of the material conveying system. The material conveying system automatically transports the slag to the transport vehicle 7000, which then moves it out of the tunnel.

[0090] The material conveying system discharges slag from the bottom of the platform; or from at least one side of the platform; or first discharges slag from the bottom of the platform, and then discharges slag through the platform from at least one side of the platform.

[0091] During muck removal operations, the tunneling operation uses a tunneling mechanism located at the front end of the platform to excavate the left and right sides of the tunnel face. At this time, the muck removal mechanism consists of an auxiliary excavator arm and a material conveying system located at the front end of the platform. The transport vehicle moves to the end of the material conveying system, and the auxiliary excavator arm pushes the muck produced during tunneling to the front end of the material conveying system. The material conveying system automatically transports the muck into the transport vehicle, which then moves it out of the tunnel. The material conveying system can be a conveyor belt structure driven by a power mechanism.

[0092] In this design, the material conveying system can perform slag removal from the bottom of the platform; or from at least one side of the platform; or first remove slag from the bottom of the platform, and then remove slag from at least one side of the platform. Since slag tends to accumulate at the bottom of the working face, the material conveying system can quickly collect slag at the bottom of the platform. Furthermore, to avoid interference with the rear components of the platform, the material conveying system is configured in a "Z" shape, removing slag from the platform first, then passing through the side of the platform, and finally removing slag from the side of the platform. This allows for more efficient slag removal.

[0093] This solution enables automatic slag removal from both sides of the trolley via a slag removal mechanism, allowing it to adapt to different construction environments. Since no access channel is required at the bottom of the trolley, the trolley can be made smaller.

[0094] This solution improves muck removal efficiency: In existing technologies, the coordination between the muck loader and the transport vehicle is often limited by the large size of the integrated unit, resulting in low muck removal efficiency. This solution aims to optimize system design to achieve simultaneous and efficient tunneling and muck removal operations, reducing waiting time and operational interference.

[0095] Meanwhile, this solution enhances the parallel operation capability of the slag loading machine and the integrated unit: Under the complex working conditions of integrated unit construction, the slag loading machine is difficult to operate in parallel with the integrated unit, limiting the improvement of slag removal efficiency. This solution aims to enhance the collaborative operation capability between the slag loading machine and the integrated unit by optimizing the layout and movement method of the slag loading machine, thereby achieving efficient and continuous slag removal operations;

[0096] Meanwhile, this solution improves the system's adaptability to complex working conditions: the existing method of using a muck loader in conjunction with a transport vehicle for muck removal is poorly adapted to tunnels constructed by integrated units, making it difficult to meet the demands of efficient tunneling. This solution aims to improve the system's adaptability to different tunnel cross-sections, tunneling speeds, and geological conditions through innovative design, ensuring high efficiency and stability in construction.

[0097] Example 2

[0098] This embodiment is similar to Embodiment 1, except that the tunneling mechanism 200 is different, such as... Figures 10-12As shown, this utility model provides a technical solution:

[0099] The tunneling mechanism 200 may include two horizontal swing mechanisms 8200 on the mounting platform 100. Each horizontal swing mechanism 8200 is connected to a vertical swing mechanism 8300, and each vertical swing mechanism 8300 is connected to the tunneling mechanism 200. The vertical swing mechanism 8300 is used to drive the tunneling mechanism 200 to swing up and down, and the horizontal swing mechanism 8200 is used to drive the vertical swing mechanism 8300 and the tunneling mechanism 200 to swing left and right as a whole.

[0100] In this embodiment, the traditional single tunneling arm 220 is improved to two or more tunneling mechanisms 200. However, setting multiple tunneling mechanisms 200 requires consideration of mutual interference, necessitating a redesign of the connection structure between the tunneling mechanism 200 and the platform 100. Since the space does not support the sliding movement of the tunneling arm 220 after installing two or more tunneling mechanisms 200, the forward and backward, left and right sliding structure of the single tunneling arm 220 is eliminated. Instead, the horizontal swing mechanism 8200 and the vertical swing mechanism 8300 drive the tunneling mechanism 200 to swing left and right and up and down. The movement of the tunneling mechanisms 200 allows for excavation operations within a certain range, avoiding interference while ensuring that the working range of multiple tunneling mechanisms 200 covers the construction area. Furthermore, multiple tunneling mechanisms 200 can operate simultaneously. Compared to single-arm tunneling machines or traditional tunneling methods, this allows for the breaking of more rock or soil per unit time. In tunnel excavation with larger cross-sections, different locations can be broken simultaneously, accelerating construction progress. The space between the tunneling mechanisms 200 allows the muck loader bucket to pass through and haul away muck during excavation, effectively improving construction efficiency. When facing complex geological conditions, such as uneven rock hardness or the presence of multiple geological structures, the working positions and angles of different tunneling mechanisms 200 can be adjusted to enhance adaptability and flexibility. One tunneling mechanism 200 can handle harder sections while another handles softer sections, ensuring continuous progress. Therefore, the operation of multiple tunneling mechanisms 200 during excavation allows for a more balanced stress distribution on the machine. Reducing machine tilting caused by excessive force on one side helps improve the accuracy and stability of tunneling, resulting in better tunnel forming quality and increased emergency response capabilities. If one tunneling mechanism 200 malfunctions, the other tunneling mechanisms 200 can still continue to work, reducing the impact of equipment failure on the overall project progress.

[0101] It should be noted that the platform 100 here has a frame structure, with a certain space and operating platform inside. The horizontal swing mechanism 8200 should be set on the side of the operating platform inside the platform 100 that is closer to the construction direction.

[0102] As an optional implementation, a rotary mechanism is also included, which is connected between the horizontal swing mechanism 8200 and the vertical swing mechanism 8300. The rotary mechanism is used to drive the vertical swing mechanism 8300 and the tunneling mechanism 200 to rotate around the axis of the rotary mechanism by a corresponding angle.

[0103] In this embodiment, by setting a slewing mechanism, the tunneling mechanism 200 can also rotate at a certain angle in the vertical plane, thereby enabling tunneling at different angles and further improving the flexibility of the excavation operation.

[0104] As an optional implementation, the rotary mechanism includes a vertical rotary table 8500 connected to the vertical swing mechanism 8300, and the vertical rotary table 8500 is connected to a rotary motor (not shown in the figure), which is mounted on the horizontal swing mechanism 8200.

[0105] In this embodiment, when a rotation operation is required, the vertical rotary table 8500 is driven to rotate a certain angle by the rotary motor, thereby causing the vertical swing mechanism 8300 and the tunneling mechanism 200 to automatically rotate a certain angle in the vertical plane. Here, the rotary motor can be a servo motor, which can precisely control the speed and direction to meet the usage requirements.

[0106] As an optional implementation, the horizontal swing mechanism 8200 includes a fourth hydraulic cylinder 8210 hinged to the frame 100, the fourth hydraulic cylinder 8210 is hinged to a horizontal rotating platform 8220, the horizontal rotating platform 8220 is rotatably connected to the frame 100, and a rotary mechanism is connected to the side of the horizontal rotating platform 8220 away from the fourth hydraulic cylinder 8210.

[0107] In this embodiment, when the tunneling mechanism 200 needs to swing left and right on the horizontal plane, the extension and retraction of the fourth hydraulic cylinder 8210 can drive the horizontal rotating table 8220 to swing on the platform 100 to a certain extent, thereby driving the rotary mechanism, the vertical swing mechanism 8300 and the tunneling mechanism 200 to swing synchronously as a whole, so as to achieve horizontal swing to the corresponding position to meet the needs of excavation operation.

[0108] As an optional implementation, a mounting bracket 8230 is fixedly installed on the platform 100, and the horizontal rotating table 8220 is rotatably connected within the mounting bracket 8230, thereby providing a certain degree of protection for moving parts such as the horizontal rotating table 8220. It should be noted that the horizontal rotating table 8220 can be a hollow structure, which can accommodate a rotary motor, resulting in a compact structure and space saving.

[0109] As an optional implementation, the vertical swing mechanism 8300 includes a boom 8310 hinged to one side of the slewing mechanism, the other end of the boom 8310 hinged to the tunneling mechanism 200, a fifth hydraulic cylinder 8320 hinged to both sides of the boom 8310, the other end of the fifth hydraulic cylinder 8320 hinged to the slewing mechanism, a sixth hydraulic cylinder 8330 hinged to the top of the boom 8310, a connecting rod assembly 8340 hinged to the sixth hydraulic cylinder 8330, and the other end of the connecting rod assembly 8340 hinged to the tunneling mechanism 200.

[0110] In this embodiment, when the tunneling mechanism 200 needs to swing up and down, the extension and retraction of the fifth hydraulic cylinder 8320 can drive the boom 8310 to rotate around the hinge pin of the slewing mechanism by a certain angle, thereby causing the boom 8310 to drive the tunneling mechanism 200 to swing up and down significantly. At this time, the sixth hydraulic cylinder 8330 extends and retracts synchronously. When fine adjustment is needed, the extension and retraction of the sixth hydraulic cylinder 8330 and the transmission action of the connecting rod assembly 8340 can drive the tunneling mechanism 200 to rotate around the hinge pin of the boom 8310 by a certain angle, thereby causing the tunneling mechanism 200 to swing up and down slightly, achieving flexible up and down swing to meet more excavation needs.

[0111] As an optional implementation, the linkage assembly 8340 includes a second hinge shaft 8341 hinged to the sixth hydraulic cylinder 8330. Two third links 8342 and a fourth link 8343 are simultaneously hinged to the second hinge shaft 8341. The other ends of the two third links 8342 are respectively hinged to both sides of the boom 8310, and the other end of the fourth link 8343 is hinged to the tunneling mechanism 200.

[0112] In this embodiment, when the sixth hydraulic cylinder 8330 extends or retracts to pull or push the second hinge shaft 8341, the third connecting rod 8342 and the fourth connecting rod 8343 move synchronously. The third connecting rod 8342 plays a certain supporting role, thereby driving the tunneling mechanism 200 to swing accordingly.

[0113] As an optional implementation, the tunneling mechanism 200 includes a breaker 223 connected to a vertical swing mechanism 8300, with a chisel 8420 connected to the other end of the breaker 223, which is suitable for rock drilling operations.

[0114] As an optional implementation, two tunneling mechanisms 200 are provided, and the two tunneling mechanisms 200 are arranged left and right on one side of the platform 100. The number of tunneling mechanisms 200 should not be too many, otherwise it will increase the equipment cost and control difficulty. According to the current excavation operation and working space, setting two tunneling mechanisms 200 can meet the basic requirements. With the two tunneling mechanisms 200 arranged left and right, they can each be responsible for the excavation operation of their respective half of the working face, resulting in high construction efficiency.

[0115] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
