Description
Technical Field
[0001] The invention relates to the technical field of engineering machinery tunneling machines, and in particular to a slope-adaptable foldable TBM cutter beam. Background Art
[0002] TBM, the full name of which is Tunnel Boring Machine, is a tunnel boring machine. TBM integrates rock breaking, slag discharge, slag removal, support and other functions in one, and each process can work together. It is currently the most technologically advanced tunnel excavation equipment in the world. As one of the key processes, the smoothness of TBM cutter changing and cutting directly affects the construction efficiency of TBM. With the expansion of TBM application areas, facing the increasingly complex tunnel lines, it is necessary to excavate in horizontal, large longitudinal slope uphill and large longitudinal slope downhill postures during construction. The traditional TBM cutter system design makes it difficult for the cutter to cope with different slope excavation postures from the main beam to the inside of the cutterhead, and the manhole on the main beam takes into account the functions of personnel passage and cutter transportation hole. The traditional cutter transportation beam is not conducive to the passage of personnel, which has a great impact on the efficiency of cutter transportation, the safety of personnel passage and the convenience of cutter transportation.
[0003] In the prior art, patent CN214062959U "A cutterhead, cutter transport tooling and tunneling machine for inclined shaft excavation" discloses a cutter transport structure for inclined shaft tunneling machines. A rack guide rail with a traveling mechanism is arranged on the top of the main beam, and the traveling mechanism is connected to an electric crane. The movement of the electric crane along the guide rail realizes the transportation of the cutter of the inclined shaft tunneling machine from the main beam to the cutterhead body. An anti-slip brake is arranged on the traveling mechanism to improve transportation safety. This patent can realize the transportation of the cutter through the meshing transmission of the gear rack, but it is not convenient for people to pass through, and the structure is complex and occupies a large space. It is not suitable for the situation where the cutter is transported from the front end of the main beam to the inside of the cutterhead.
[0004] In summary, when existing tunnel boring machines face complex tunnels and need to excavate in a horizontal, uphill or downhill posture, after the conventional TBM cutter is transported to the manhole position of the main beam, the cutter is transferred to the inside of the cutter head through the integrated trolley crane on the cutter beam. The cutter beam mechanism is rigid and cannot be adjusted. In uphill or downhill situations, the integrated trolley crane on the cutter beam is prone to sudden slide down, and there is a risk of collision between personnel from the main beam manhole to the inside of the cutter head. Therefore, the development of a foldable TBM cutter beam mechanism that can achieve slope adaptability adjustment has become a problem that needs to be solved urgently. Summary of the invention

The hoisting mechanism is slidably connected to the cutter beam mechanism, used for hoisting the cutter, and can drive the cutter to slide on the first cutter beam or the second cutter beam.
[0009] A further technical solution is that the movable connection between the second blade beam and the first blade beam is a foldable connection, and the second blade beam can be foldably stored in or extended from the first blade beam.

[0011] A further technical solution is that the first blade beam is an I-beam, the slide groove is located on the web of the I-beam, the second blade beam includes two C-beams with openings facing each other, and the web is sandwiched in the gap between the two C-beams. At one end close to the I-beam, the two C-beams are connected by the slide shaft, and at one end away from the I-beam, the two C-beams are connected by a connecting plate.
[0012] A further technical solution is that a ball and a ball cover plate are provided between the top of the C-beam and the I-beam.

[0016] A further technical solution is that a driving device is fixedly connected to the mounting seat, and the driving device can drive the second knife beam to slide back and forth along the sliding groove.

DETAILED DESCRIPTION
[0033] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0034] This embodiment provides a slope-adaptable foldable TBM tool carrier beam, referring to Figure 1-Figure 3As shown, it includes a cutter beam mechanism 1, an adjustment mechanism 2 and a hoisting mechanism 3 arranged inside a tunnel boring machine body 4. The cutter beam mechanism 1 includes a first cutter beam 11, and a second cutter beam 12 movably connected to the first cutter beam 11, and the second cutter beam 12 can perform telescopic movement along the extension direction of the first cutter beam 11. The first cutter beam 11 and the second cutter beam 12 are connected to the tunnel boring machine body 4 through the adjustment mechanism 2, and the adjustment mechanism 2 can adjust the inclination angle of the first cutter beam 11 and the second cutter beam 12 according to the posture of the tunnel boring machine to maintain the first cutter beam 11 and the second cutter beam 12 in a horizontal state. The hoisting mechanism 3 is slidably connected to the cutter beam mechanism 1, and is used to hoist the cutter, and can drive the cutter to slide on the first cutter beam 11 or the second cutter beam 12.
[0035] Specifically, the present invention optimizes the tool transport structure between the main beam 10 and the cutter head body, and on the basis of the original single steel beam structure, keeps the cutter head, main drive, main beam 10 and belt conveyor structures unchanged, so that the cutter head, main drive, main beam 10 and belt conveyor are provided with an angle adjustment function, so as to solve the problem of the hoisting mechanism 3 slipping during inclined excavation and the head collision of personnel when passing. The specific form of the hoisting mechanism 3 here is an integrated trolley crane. The first cutter beam 11 and the second cutter beam 12 are connected to the main body 4 of the tunnel boring machine through the adjustment mechanism 2, and are specifically connected to the side plates on both sides of the belt conveyor. This enables the cutter transport beam to adjust its inclination angle according to the posture of the tunnel boring machine, ensuring that the first cutter beam 11 and the second cutter beam 12 can maintain a horizontal state at any slope. The tunnel boring machine's excavation ability under complex geological conditions is enhanced, especially in tunnel construction with large slope changes, and a stable excavation efficiency can be maintained. At the same time, the installation and replacement of the cutter also has better positioning accuracy. According to the external posture data of the tunnel boring machine, the adjusting mechanism 2 is precisely controlled to ensure that the first blade beam 11 and the second blade beam 12 are always in a horizontal state, thereby avoiding the forward or backward sliding of the lifting mechanism 3 due to the inclination angle of the blade beam, and indirectly controlling the possibility of the machine causing harm to personnel.
[0036] In this embodiment, the movable connection between the second cutter beam 12 and the first cutter beam 11 is a foldable connection, and the second cutter beam 12 can be folded and stored in or extended from the first cutter beam 11. The space utilization rate is improved. When excavation or tool transportation is not required, the second cutter beam 12 can be folded and stored inside the first cutter beam 11, which greatly saves space, making the structure of the entire TBM (full-section hard rock tunnel boring machine) more compact, providing more space for the main beam and manhole, and facilitating personnel to enter the cutter head through the manhole to perform maintenance or replace tools and other tasks. The foldable second cutter beam 12 is more convenient and quicker to maintain and replace.
[0037] Specific, combined Figure 4-Figure 5As shown, in this embodiment, the first blade beam 11 and the second blade beam 12 are relatively slidably arranged, and along the extension direction of the first blade beam 11, the first blade beam 11 is provided with a slide groove 111, and one end of the second blade beam 12 is provided with a slide shaft 121 slidably connected to the slide groove 111. The sliding connection between the slide groove 111 and the slide shaft 121 can ensure the stability of the second blade beam 12 during the sliding process, and it is preferred that the slide shaft 121 is provided in multiple groups, and in this embodiment, there are 4 groups.
[0038] Specifically, the first blade beam 11 is an I-beam, which is made of steel and has excellent strength and pressure resistance. It can withstand large loads and pressures and is not easily deformed, thereby ensuring the stability and safety of the first blade beam 11 structure.
[0039] The slide groove 111 is located on the web of the I-beam, and the second blade beam 12 includes two C-beams with openings facing each other, and the web is sandwiched in the gap between the two C-beams. At one end close to the I-beam, the two C-beams are connected by a sliding shaft 121, and at one end away from the I-beam, the two C-beams are connected by a connecting plate 122.
[0040] Combination Figure 7-10 As shown, it should be noted that the C-beam is preferably a channel steel, and the two channel steels can just fit into the axial notch of the I-beam and clamp the web of the I-beam. This forms a stable connection between the second knife beam 12 and the I-beam, effectively preventing the knife beam from shaking or shifting during use, thereby enhancing the stability of the entire structure. The structural design of the two C-beams itself has a high load-bearing capacity, and connecting them through the sliding shaft 121 and the connecting plate 122 further enhances this load-bearing capacity. This design enables the second knife beam 12 to withstand a greater load and meet the high strength requirements in excavation or cutting operations. The sliding connection design of the slide 111 and the sliding shaft 121 allows the second knife beam 12 to be easily installed on the I-beam or removed from the I-beam. The installation and disassembly process is simplified, maintenance costs are reduced, and work efficiency is improved.
[0041] Specifically, in this embodiment, a ball 5 and a ball cover plate 6 are provided between the top of the C-beam and the I-beam, a ball groove 113 is provided on the I-beam corresponding to the ball 5 ; and a roller sleeve 124 is sleeved on the sliding shaft 121 .
[0042] The rolling of the ball 5 arranged between the C-beam and the I-beam in the ball groove 113 greatly reduces the friction between the C-beam and the I-beam. This rolling friction has a smaller friction coefficient than sliding friction, so it can significantly reduce wear and extend the service life of the C-beam and the I-beam. The cooperation of the ball 5 and the ball groove 113 makes the movement of the C-beam relative to the I-beam more flexible and the movement accuracy higher. The design of the ball 5 and the ball cover plate 6 not only reduces the friction, but also can effectively disperse and absorb the impact and vibration during the movement, thereby enhancing the stability and reliability of the structure. The roller sleeve 124 also plays a role in reducing friction and wear. It converts the movement of the sliding shaft 121 in the slide groove 111 from sliding to rolling, making it smoother, reducing energy loss and improving the overall efficiency of the system.
[0043] like Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the adjustment mechanism 2 includes multiple groups of adjustment devices 21, the first blade beam 11 is connected to the tunnel boring machine body 4 through at least two groups of adjustment devices 21, and the second blade beam 12 is connected to the tunnel boring machine body 4 through at least one group of adjustment devices 21. The connection method of multiple groups of adjustment devices 21 helps to disperse the force and vibration generated during the tunneling process, thereby enhancing the overall stability of the tunnel boring machine and reducing the shaking and deviation of the tunnel boring machine during operation.
[0044] Specifically, in this embodiment, the adjustment device 21 includes a driving member 211 and a connecting seat 212. One end of the connecting seat 212 is fixed to the tunnel boring machine body 4, and the other end is hinged to the driving member 211. The output end of the driving member 211 is provided with a retractable connecting rod 213, and the end of the connecting rod 213 is hinged to the first blade beam 11 or the second blade beam 12. The driving member 211 here can be selected from any one of the linear drive devices 8 such as hydraulic cylinders, motors or cylinders. In this embodiment, a hydraulic cylinder is selected. The purpose of the hinge is to achieve adaptive adjustment of the first blade beam 11 and the second blade beam 12 to ensure the horizontal adjustment accuracy. The specific hinge is installed by plugging the pin shaft 9 into the pin hole.
[0045] Combination Figure 4 and Figure 5 Specifically, in this embodiment, the tops of both ends of the first blade beam 11 are provided with connecting ears 112, and the connecting rod 213 is hinged to the connecting ears 112; the connecting ears 112 are mainly used to enhance the strength of the hinge and ensure the stability of the connection of the first blade beam 11. Figure 7 A mounting seat 7 is provided on the top of the second blade beam 12, and the connecting rod 213 is hinged to the mounting seat 7. The mounting seat 7 is mainly used to enhance the strength of the hinge and ensure the stability of the connection of the second blade beam 12.
[0046] In this embodiment, the mounting seat 7 is fixedly connected with a driving device 8, and the driving device 8 can drive the second blade beam 12 to slide back and forth along the slide groove 111. Figure 8 As shown, the drive device 8 is a motor, and in practice, the angle adjustment can also be achieved by using hydraulic structures, motors, etc. The motor here can be selected as a servo or a stepper, preferably a servo, which has better adjustment accuracy. Specifically, in this embodiment, along the extension direction of the second knife beam 12, a spur rack 123 is provided on the second knife beam 12, and the drive device 8 includes a drive motor 81, which is connected to the spur rack 123 in a transmission connection. Specifically, the output end of the motor is connected to a cylindrical gear, and the cylindrical gear is connected to the spur rack 123 in a transmission connection. Compared with other complex transmission mechanisms, the coordination between the gear and the rack is simpler, which reduces the failure points and the difficulty of maintenance.
[0047] This embodiment provides an automated method to achieve telescopic folding of the knife beam. In actual use, the telescopic folding of the knife beam can be achieved by manual control. The cylindrical gear on the drive motor 81 is disengaged from the spur rack 123 on the second knife beam 12. When the on-site personnel pass by, the second knife beam 12 can be manually telescopically folded by hand.
[0048] In summary, the actual construction process of the tunnel boring machine equipped with the slope-adaptive foldable TBM cutter beam provided in this embodiment is as follows:
[0049] When the tunnel boring machine excavates to the slope route, the control room senses the excavation posture.
[0050] According to the stroke feedback of the hydraulic cylinders on the horizontal adjustment mechanism 2 connected to the two ends of the first cutter beam 11, the extension amount of the two hydraulic cylinders is adjusted to the appropriate position to keep the first cutter beam 11 horizontal, prevent the integrated trolley crane from suddenly sliding during slope excavation and affect the safety of the workers, and improve the efficiency of cutter operation during slope excavation.
[0051] When a person needs to pass through the manhole on the main beam 10, the second blade beam 12 is retracted into the first blade beam 11 through the gear meshing transmission by controlling the driving motor 81 to prevent the person from hitting his head when passing through.
[0052] It should be noted that all directional indications in this embodiment (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
