Description

Technical Field

[0001] The invention relates to the technical field of shield cutters, in particular to a shield cutter capable of impacting and breaking rocks. Background Art

[0002] Shield machines are crucial equipment in tunnel construction, widely used in projects such as subways, railways, and highway tunnels. The cutterhead, a crucial tool for tunneling and rock breaking, is installed on the machine's cutterhead. As the machine advances, the cutterhead rotates, driving the cutterhead to roll across the rock surface. The cutterhead applies force to the rock through various methods, including rolling, crushing, tensioning, impacting, and shearing, destroying its structure, breaking it and causing it to flake off, thereby completing tunneling and rock breaking. However, when tunneling in some extremely hard rock formations, the high hardness of the rock makes it difficult to break it through squeezing, resulting in the cutterhead "turning but not advancing." This causes severe wear on the cutterhead, low shield machine tunneling efficiency, and a serious impact on construction progress.

[0037] The present invention provides a shield cutter capable of impacting and breaking rocks, such as Figure 1As shown, the shield cutter capable of impacting and breaking rock includes a tool 1, a drive device 3 and an impact rod 2; a plurality of mounting holes 100 are provided on the tool 1; the mounting holes 100 are arranged along the radial extension of the tool 1; the drive device 3 is provided in the mounting holes 100; the impact rod 2 is located in the mounting hole 100 and is connected to the drive device 3; the impact rod 2 is used to extend out of and retract into the mounting hole 100 under the drive of the drive device 3.

[0038] Specifically, there are multiple impact rods 2, and each of the impact rods 2 corresponds to the mounting holes 100 one by one, that is, each mounting hole 100 is correspondingly provided with one impact rod 2 and one drive device 3; the drive device 3 is connected to the impact rod 2 and is used to control the extension and retraction of the impact rod 2 within the mounting hole 100. The mounting hole 100 extends to the outer surface of the cutter 1. When the drive device 3 drives the impact rod 2 to extend, the head of the impact rod 2 can extend out of the mounting hole 100 and beyond the outer surface of the cutter 1, thereby generating a certain impact force on the rock; when the impact rod 2 is no longer needed to assist in rock breaking, the drive device 3 can drive the impact rod 2 to retract into the mounting hole 100, and the rock is punched only through the outer surface of the cutter 1.

[0039] It can be seen that in this application, while breaking the rock by the tool 1, the impact rod 2 is also added to the tool 1, so that when the hardness is high and the tool 1 itself is difficult to complete the excavation, the driving device 3 can be turned on, and the impact rod 2 is driven by the driving device 3 to extend out of the mounting hole 100 and impact the rock, thereby improving the rock breaking ability of the shield cutter that can impact and break rock.

[0040] Furthermore, since the driving device 3 can drive the extension and retraction of the impact rod 2, the extension rate of the impact rod 2 can be adjusted by adjusting the driving force of the driving device 3, thereby adjusting the impact force of the impact rod 2 when breaking the rock.

[0041] In one embodiment of the present application, the plurality of mounting holes 100 are evenly arranged radially around the central axis of the tool 1 .

[0042] Specifically, the plurality of mounting holes 100 are radially distributed, centered about the central axis of the tool 1. All mounting holes 100 are located in the same plane and are evenly distributed. Consequently, the plurality of impact rods 2 are evenly distributed along the circumference of the tool 1, with the impact paths of the impact rods 2 extending radially along the tool 1. The impact paths of the plurality of impact rods 2 are radially arranged.

[0043] In this embodiment, the radial arrangement of the multiple mounting holes 100 and the multiple impact rods 2 can make the impact force more evenly distributed to the rock surface around the tool 1; this can avoid local wear of the tool 1 caused by concentrated impact, improve the overall rock breaking efficiency of the tool 1, and reduce additional vibration and wear caused by imbalance, thereby enhancing the stability of the overall structure of the shield cutter capable of impacting and breaking rocks, and extending its service life.

[0044] It can be understood that each of the impact rods 2 is driven by a corresponding driving device 3, so that each of the impact rods 2 can be independently controlled and driven.

[0045] In one embodiment of this application, Figure 1 and Figure 3 As shown, the shield cutter capable of impact rock breaking also includes an electromagnetic energy storage device 6; a center hole is provided on the cutter 1, and the center hole is arranged along the axial direction of the cutter 1; the electromagnetic energy storage device 6 is arranged in the center hole and is electrically connected to the driving device 3.

[0046] Specifically, the electromagnetic energy storage device 6 is arranged at the center of the tool 1 and is electrically connected to the drive device 3. When the shield cutter that can impact and break rock breaks rock and the tool 1 rotates, the electromagnetic energy storage device 6, based on the principle of electromagnetic induction, utilizes the rotational motion of the tool 1 to cut the magnetic induction coil through the rotating magnet, induces an electromotive force in the magnetic induction coil, generates current, and stores it through a battery to realize the conversion of mechanical energy into electrical energy, and then generates electricity and stores it, thereby supplying energy to the drive device 3. The energy stored during rock breaking can be used for the impact rock breaking of the impact rod 2.

[0047] In this embodiment, the electromagnetic energy storage device 6 generates electrical energy through the rotational motion of the tool 1, thereby converting the mechanical energy generated by the rotational motion of the tool 1 into stored electrical energy. This ensures that the energy generated by the tool 1 during rotation is not wasted and can be used by the drive device 3 to drive the impact of the impact rod 2 when needed to assist in rock breaking, effectively improving energy utilization, reducing energy waste, and recycling the rotational energy of the tool 1. The electromagnetic energy storage device 6 is prior art, and the structure of the electromagnetic energy storage device 6 will not be described in detail here.

[0048] The drive device 3 can also be connected to an external power source. In this embodiment, the addition of the electromagnetic energy storage device 6 allows the cutter 1 to generate electricity independently as it rotates, eliminating the need for an additional external power supply. For shield machines operating in complex environments such as tunnel boring, reducing reliance on external power or hydraulic systems can reduce system complexity and enhance the ability of the impact-breaking shield cutter to operate independently. This avoids operational interruptions caused by the complex working environment of the shield machine and unstable external power supply, effectively minimizing the risk of power outages.

[0049] At the same time, the electromagnetic energy storage device 6 supplies energy to the drive device 3 to drive the impact rod 2 to extend and generate impact force. The drive device 3 can be driven hydraulically, pneumatically, or electromagnetically. In one embodiment of the present application, the drive device 3 is driven electromagnetically. Compared with hydraulic and pneumatic drives, the electromagnetic drive method requires less space, is more convenient to integrate, and is easier to control.

[0050] The shield cutter capable of impacting and breaking rock also includes a shock-absorbing structure; a mounting groove is provided on the inner wall of the cutter 1, the mounting groove is connected to the center hole and corresponds to the mounting hole 100; the shock-absorbing structure is located in the mounting groove.

[0051] Specifically, the shock-absorbing structure is located between the driving device 3 and the electromagnetic energy storage device 6, and the shock-absorbing structure is accommodated and positioned by the mounting groove, thereby absorbing and reducing the impact force generated on the driving device 3 when the impact rod 2 is retracted into the mounting hole 100, so as to ensure the stability of the overall structure of the shield cutter that can impact and break rocks.

[0052] In one embodiment of this application, Figure 1 As shown, the shock-absorbing structure includes a shock-absorbing ring 4; the mounting groove is arranged in a closed loop structure along the circumferential direction of the center hole, and the shock-absorbing ring 4 is sleeved on the outside of the electromagnetic energy storage device 6; each of the mounting holes 100 corresponds to the shock-absorbing ring 4.

[0053] Specifically, the damping ring 4 is a closed-loop structure. The damping ring 4 is sleeved outside the electromagnetic energy storage device 6 and located within the mounting slot. Thus, through the positioning of the mounting slot, the damping ring 4 is positioned between the drive device 3 and the electromagnetic energy storage device 6. Since the damping ring 4 is a closed-loop structure, all mounting holes 100 correspond to the damping ring 4, that is, all drive devices 3 correspond to the damping ring 4. This simplifies the design and manufacturing process, reduces the number of components, and reduces complexity. The assembly and maintenance of the damping ring 4 are more convenient, saving time and cost.

[0054] At the same time, the shock-absorbing ring 4 simultaneously absorbs and disperses the vibration and impact force generated by multiple impact rods 2, providing a more uniform shock absorption effect. Compared to installing shock-absorbing rings 4 individually, the integrated design can more effectively resist impact forces and improve overall performance. Compared to installing separate shock-absorbing devices at each mounting hole 100, the integrated design of the shock-absorbing ring 4 in this embodiment can more effectively resist impact forces, improve overall performance, and avoid the localized stress concentration that may be generated by multiple discrete shock-absorbing devices when subjected to impact, thereby reducing the risk of failure due to localized wear.

[0055] like Figure 1 As shown, the shield cutter capable of impact rock breaking also includes a cutter shaft seat 10 and two second shock-absorbing structures 5; the cutter shaft seat 10 has two clamping arms; the cutter 1 is located between the two clamping arms, and the two clamping arms are distributed along the axial direction of the cutter 1; the two second shock-absorbing structures 5 are distributed on both sides of the axial direction of the cutter 1; the second shock-absorbing structure 5 is arranged between the cutter 1 and the clamping arms.

[0056] Specifically, the tool shaft seat 10 is used to assemble and position the tool 1 ; the two clamping arms respectively clamp the tool 1 along the axial direction of the tool 1 , thereby achieving the installation and positioning of the tool 1 on the tool shaft seat 10 .

[0057] The second damping structure 5, located between the cutter 1 and the clamping arm, effectively absorbs vibrations generated by the cutter 1 during operation, reducing the transmission of vibrations to the cutter shaft seat 10 and other structures, preventing damage to other components, and improving the stability of the entire system. The provision of the second damping structure 5 also reduces noise and vibration generated during operation by the cutter 1, improving operator comfort, reducing fatigue damage caused by vibration, and reducing wear on the cutter 1 and the cutter shaft seat 10, thereby extending the overall service life of the shield cutter capable of impact rock breaking.

[0058] At the same time, the second shock-absorbing structure 5 also helps to improve the dynamic stability of the tool 1, reduce the jumping and imbalance caused by vibration, and improve the stability and precision of the tool 1 during the cutting process.

[0059] In the present application, the shock-absorbing structure and the second shock-absorbing structure 5 are both made of wear-resistant and highly elastic rubber material.

[0060] like Figure 1 and Figure 2 As shown, the tool 1 includes a tool body 101 and a cutting ring 102 , wherein the cutting ring 102 is sleeved on the tool body 101 ; the mounting hole 100 penetrates the cutting ring 102 from the outer surface of the cutting ring 102 and extends into the tool body 101 .

[0061] Specifically, the cutting ring 102 is coaxially arranged with the tool body 101, and an assembly groove is provided on the outer side of the tool body 101, and a portion of the cutting ring 102 is located in the assembly groove; through the cooperation between the cutting ring 102 and the assembly groove, the contact area between the cutting ring 102 and the tool body 101 can be increased, thereby preventing the cutting ring 102 from separating from the tool body 101 during high-speed rotation of the tool 1.

[0062] The cutter ring 102 is made of high-strength alloy material; in this application, under the premise of ensuring the overall structural strength of the cutter ring 102, different numbers of the impact rods 2 can be arranged according to the strength of the excavated stratum, and the mounting holes 100 can be arranged at different intervals accordingly to achieve the best rock breaking effect.

[0063] like Figure 1 and Figure 3 As shown, the shield cutter capable of impacting and breaking rock further includes a control system 11 and a wireless communication system 12. The control system 11 is electrically connected to the drive device 3, and the wireless communication system 12 is wirelessly connected to the control system 11 and the drive device 3 respectively.

[0064] Specifically, the wireless communication system 12 is used to realize wireless communication between the control system 11 and the drive device 3, thereby wirelessly controlling the start and stop of the drive device 3. There is no need to use wires to connect the control system 11 and the drive device 3, thereby avoiding adverse interference of the wires on the rotation of the tool 1 when using wires.

[0065] At the same time, when the shield machine penetrates deep into the stratum, the staff can wirelessly control the driving device 3 through the control system 11 on the ground, which improves the convenience of operation.

[0066] The shield cutter capable of impacting and breaking rock further includes a sensor component, which is disposed in the cutter 1 and is wirelessly connected to the wireless communication system 12 .

[0067] Specifically, the sensor assembly is disposed within the cutter 1 and wirelessly connected to the wireless communication system 12. Wireless communication can then be established between the sensor assembly and the control system 11 via the wireless communication system 12. The sensor assembly is used to monitor the working status of the rock-breaking shield cutter in real time. The control system 11 can adjust the output of the drive device 3 based on data fed back by the sensor assembly, thereby adjusting the magnitude and frequency of the impact force generated by the impact rod 2.

[0068] In one embodiment of this application, Figure 1and Figure 3 As shown, the sensor assembly includes an acceleration sensor 8 and a position sensor 7 ; the acceleration sensor 8 and the position sensor 7 are both located in the tool body 101 and are both capable of wireless communication with the wireless communication system 12 .

[0069] Specifically, the position sensor 7 can determine the real-time specific position of the tool 1 during the rotation cycle; when the tool 1 is at the appropriate angle, the control system 11 can control the drive device 3 to start at the optimal time based on the data transmitted by the position sensor 7, so that the impact rod 2 can apply the impact force at the optimal time, so that the impact rod 2 can act on the rock at the appropriate position and angle, thereby ensuring that the impact rod 2 can accurately act on the rock-breaking point of the tool 1 in each cycle, improving rock-breaking efficiency, thereby improving impact efficiency and reducing energy waste. This real-time feedback can avoid impact misalignment or empty strikes, thereby improving the rock-breaking effect of the shield cutter capable of impact rock-breaking.

[0070] The position sensor 7 can also monitor the displacement limit of the cutter 1 to prevent operation beyond a safe range. For example, if the cutter 1 deviates from a preset position or moves excessively, the control system 11 can automatically adjust or shut down the system based on feedback from the position sensor 7, protecting the cutter 1 from damage and extending the service life of the shield cutter capable of impact rock breaking.

[0071] The acceleration sensor 8 can monitor in real time the acceleration changes of the tool 1 during the rock breaking process, especially the acceleration changes of the tool 1 when the driving device 3 applies the impact force. By measuring the magnitude and frequency of the acceleration, the control system 11 can judge the intensity and effect of each impact and make dynamic adjustments to ensure that the impact force is sufficient and effective in breaking the rock.

[0072] By recording the vibration feedback of the cutter 1 on the rock surface after impact, the acceleration sensor 8 can provide key information about rock-breaking efficiency. If the vibration detected by the acceleration sensor 8 is excessive or uneven, it may indicate a malfunction of the cutter 1, a change in rock hardness, or system imbalance, and the magnitude and frequency of the driving force output by the drive device 3 need to be adjusted. Furthermore, if the force applied to the cutter 1 is uneven or the impact force between the cutter 1 and the rock fluctuates abnormally, the sensor will sense these irregular acceleration changes. By monitoring these acceleration changes with the acceleration sensor 8, real-time balancing and adjustments can be made to prevent unstable vibrations from adversely affecting the cutter 1 and the overall structure of the shield machine.

[0073] The sensor assembly further includes a current sensor 9 , which is connected in series between the electromagnetic energy storage device 6 and the drive device 3 and is used to monitor the operating current of the drive device 3 or the electromagnetic energy storage device 6 in real time.

[0074] Specifically, by detecting the magnitude of the operating current, the control system 11 can determine whether the drive device 3 is operating normally. If the current is too large or too small, it may indicate that the equipment is overloaded or malfunctioning; the control system 11 can then adjust operating parameters based on this feedback to avoid damage to the equipment. At the same time, the current sensor 9 can provide feedback on current changes in the drive device 3. Based on the relationship between current and impact force, the control system 11 can determine the magnitude of the current impact force and control the output of the drive device 3, thereby automatically adjusting the impact force of the impact rod 2 to ensure that the appropriate impact strength is applied to rocks of different hardnesses, thereby improving rock breaking efficiency and reducing wear on the tool 1.

[0075] In one embodiment of this application, Figure 1 and Figure 2 As shown, the impact rod 2 includes a rod body 21 and an impact head 22 ; one end of the rod body 21 is connected to the driving device 3 ; the impact head 22 is arranged at the end of the rod body 21 away from the driving device 3 .

[0076] Specifically, the rod 21 is axially arranged along the radial direction of the cutter 1. One end of the rod 21 is connected to the drive device 3, and the other end is connected to the impact head 22. Driven by the drive device 3, the impact head 22 is driven to reciprocate, generating a continuous impact force. The impact head 22 is made of a high-hardness and wear-resistant material, which can effectively transmit the impact force and ensure efficient rock breaking.

[0077] In one implementation of the present embodiment, the impact head 22 is a spherical impact head; the spherical impact head can increase the contact area with the rock. Compared with a pointed head or a flat head, the spherical structure can disperse stress more evenly, thereby avoiding excessive local stress and reducing damage to the impact head 22 or the cutter ring 102. At the same time, it can also more effectively apply impact force to the rock surface to achieve the purpose of breaking the rock.

[0078] At the same time, the spherical impact head allows the impact force to be more evenly transmitted to the rock surface, reducing lateral deviation of the impact rod 2 during the impact process. The spherical design of the impact head 22 helps to concentrate the axial impact force at the center of the impact head 22, thereby more efficiently transferring kinetic energy to the rock, further improving rock breaking efficiency. Moreover, compared to sharp or angular designs, the spherical impact head can evenly distribute pressure when in contact with the rock, which is less likely to cause localized wear and damage, thereby extending the service life of the impact rod 2.

[0079] In summary, the present invention provides a shield cutter capable of impact rock breaking, comprising: a cutter; a plurality of mounting holes provided on the cutter; the mounting holes being arranged along the radial extension of the cutter; a drive device provided in the mounting hole; an impact rod located in the mounting hole and connected to the drive device; the impact rod being used to extend and retract into the mounting hole under the drive of the drive device. In this application, while the cutter is used to break rock, the impact rod is also added to the cutter, so that when faced with a high hardness and the cutter itself is difficult to complete excavation, the drive device can be turned on, and the impact rod can be driven by the drive device to extend out of the mounting hole and impact the rock, thereby improving the rock breaking ability of the shield cutter capable of impact rock breaking.
