Description

Technical Field

[0002] The shield machine is an important equipment in tunnel construction and is widely used in subway, railway, highway tunnel and other projects. The roller cutter is installed on the cutterhead of the shield machine as an important tool for tunneling and breaking rocks. When the shield machine moves forward, the cutterhead rotates and drives the roller cutter to roll on the rock surface. The roller cutter exerts force on the rock through rolling cutting, crushing, tensioning, impact and shearing, destroying the structure of the rock, breaking and peeling it off, thereby completing the tunneling and breaking of the rock. However, when tunneling in some extremely hard rock formations, due to the high hardness of the rock, the rock is difficult to break through squeezing, and the roller cutter will "only turn but not move forward", resulting in serious wear of the roller cutter and low tunneling efficiency of the shield machine, which seriously affects the construction progress.

[0037] The present invention provides a shield cutter capable of impact breaking rocks, such as Figure 1As shown, the shield cutter capable of impact breaking rock comprises a tool 1, a driving device 3 and an impact rod 2; a plurality of mounting holes 100 are arranged on the tool 1; the mounting holes 100 are arranged along the radial extension of the tool 1; the driving device 3 is arranged in the mounting holes 100; the impact rod 2 is located in the mounting hole 100 and is connected to the driving device 3; the impact rod 2 is used to extend out and retract into the mounting hole 100 under the drive of the driving 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 driving device 3; the driving device 3 is connected to the impact rod 2, and is used to control the extension and retraction of the impact rod 2 in the mounting hole 100. The mounting hole 100 extends to the outer surface of the tool 1, so when the driving 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 exceed the outer surface of the tool 1, thereby generating a certain impact force on the rock; when the impact rod 2 is not needed to assist in breaking the rock, the driving device 3 can drive the impact rod 2 to retract into the mounting hole 100, and only punch the rock through the outer surface of the tool 1.

[0039] It can be seen that in the present application, while breaking rocks 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 rocks.

[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 rocks.

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

[0042] Specifically, the plurality of mounting holes 100 are radially distributed, and are radially distributed in a manner centered on the central axis of the tool 1; all the mounting holes 100 are located in the same plane and are evenly distributed. Then, the plurality of impact rods 2 are evenly distributed along the circumferential direction of the tool 1, and the impact paths of the impact rods 2 are arranged along the radial extension of 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 can also reduce additional vibration and wear caused by imbalance, enhance the stability of the overall structure of the shield cutter that can impact and break rocks, and extend 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 the present application, Figure 1 and Figure 3 As shown, the shield cutter capable of impact breaking rocks 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 a 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 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 electrical energy for storage, so that the energy generated by the tool 1 during the rotation process will not be 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 forming the recycling of the rotational energy of the tool 1. The electromagnetic energy storage device 6 is a 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; and in this embodiment, the addition of the electromagnetic energy storage device 6 can generate electricity by itself when the cutter 1 rotates, without the need for an additional external power supply. For shield machines in complex environments such as tunnel excavation, reducing dependence on external power or hydraulic systems can reduce system complexity and enhance the ability of the shield cutter that can impact and break rock to operate independently, thereby avoiding operation interruptions caused by the complex working environment of the shield machine and unstable external power supply, and effectively avoiding the risk of power supply interruptions.

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

[0050] The shield cutter capable of impact breaking rocks 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 is accommodated and positioned by the mounting groove, thereby absorbing and mitigating 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 the present application, Figure 1 As shown, the shock absorbing structure includes a shock absorbing ring 4; the mounting grooves are arranged around the circumferential direction of the center hole to form a closed loop structure, and the shock absorbing ring 4 is sleeved outside the electromagnetic energy storage device 6; each of the mounting holes 100 corresponds to the shock absorbing ring 4.

[0053] Specifically, the shock absorbing ring 4 is a closed-loop structure, and the shock absorbing ring 4 is sleeved outside the electromagnetic energy storage device 6 and is located in the mounting groove, so that it is positioned between the driving device 3 and the electromagnetic energy storage device 6 through the limit of the mounting groove. Since the shock absorbing ring 4 is a closed-loop structure, all mounting holes 100 correspond to the shock absorbing ring 4, that is, the driving device 3 corresponds to the shock absorbing ring 4, which can simplify the design and manufacturing process, reduce the number of components, reduce complexity, and make the assembly and maintenance of the shock absorbing ring 4 more convenient, saving time and cost.

[0054] At the same time, the shock absorbing ring 4 can simultaneously absorb and disperse the vibration and impact force generated by multiple impact rods 2, providing a more uniform shock absorbing effect. Compared with installing the shock absorbing ring 4 separately, the overall design can more effectively resist the impact force and improve the overall performance. Compared with installing a shock absorbing device separately at each of the mounting holes 100, the overall design of the shock absorbing ring 4 in this embodiment can more effectively resist the impact force, improve the overall performance, and avoid the local stress concentration that may be generated by multiple dispersed shock absorbing devices when they are impacted, thereby reducing the risk of failure caused by local wear.

[0055] like Figure 1 As shown, the shield cutter capable of impact breaking rocks 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 clamp the tool 1 along the axial direction of the tool 1 respectively, thereby achieving installation and positioning of the tool 1 on the tool shaft seat 10 .

[0057] The second shock absorbing structure 5 is located between the tool 1 and the clamping arm, and can effectively absorb the vibration generated by the tool 1 during operation, reduce the transmission of vibration to the tool shaft seat 10 and other structures, prevent vibration from damaging other components, and improve the stability of the entire system. The setting of the second shock absorbing structure 5 can also reduce the noise and vibration generated by the tool 1 during operation, improve the comfort of operation, reduce fatigue damage caused by vibration, reduce the wear of the tool 1 and the tool shaft seat 10, and thus extend 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 surface 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 detaching 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 the present 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 impact breaking rocks also 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, so as to wirelessly control the start and stop of the drive device 3. Then, there is no need to use wires to connect the control system 11 and the drive device 3, thereby avoiding the 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 rocks further comprises a sensor assembly, which is disposed in the cutter 1 and is wirelessly connected to the wireless communication system 12 .

[0067] Specifically, the sensor assembly is arranged in the cutter 1, and the sensor assembly is wirelessly connected to the wireless communication system 12, so that the sensor assembly and the control system 11 can wirelessly communicate through the wireless communication system 12. The sensor assembly is used to monitor the working state of the shield cutter capable of impacting and breaking rocks in real time, and the control system 11 can adjust the output of the driving device 3 according to the 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 the present 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 both are 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 in the rotation cycle; when the tool 1 is at a suitable angle, the control system 11 can control the drive device 3 to start at the best time according to the data transmitted by the position sensor 7, so that the impact rod 2 can apply impact force at the best time, so that the impact rod 2 can act on the rock at the appropriate position and angle, which can ensure that the impact rod 2 can accurately act on the rock breaking point of the tool 1 in each cycle, improve the rock breaking efficiency, thereby improving the impact efficiency and reducing energy waste. This real-time feedback can avoid impact dislocation or empty strikes, thereby improving the rock breaking effect of the shield cutter that can impact and break rocks.

[0070] At the same time, the position sensor 7 can also be used to monitor the displacement limit of the cutter 1 to prevent operations beyond the safety range. For example, when the cutter 1 deviates from the preset position or moves excessively, the control system 11 can automatically adjust or shut down according to the feedback of the position sensor 7 to protect the cutter 1 from damage and extend 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 to which the tool 1 is subjected during the rock breaking process, especially the acceleration changes to the tool 1 when the driving device 3 applies an impact force. By measuring the magnitude and frequency of the acceleration, the control system 11 can determine 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 tool 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 too large or uneven, it may mean that the tool 1 is faulty, the rock hardness changes, or the system is unbalanced, and the magnitude and frequency of the driving force output by the drive device 3 need to be adjusted. At the same time, if the tool 1 is unevenly stressed or the impact force between it and the rock fluctuates abnormally, the sensor will sense these irregular acceleration changes. By monitoring the acceleration changes through the acceleration sensor 8, balance and adjustment can be performed in real time to avoid unstable vibrations from causing adverse effects on the tool 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 working 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 mean that the equipment is overloaded or malfunctioning; then, the control system 11 can adjust the operating parameters based on these feedbacks to avoid damaging the equipment. At the same time, the current sensor 9 can feedback the current changes of the drive device 3. Through the relationship between the current and the 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, ensuring that appropriate impact strength is applied to rocks of different hardness, improving rock breaking efficiency, and reducing wear of the tool 1.

[0075] In one embodiment of the present 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 an end of the rod body 21 away from the driving device 3 .

[0076] Specifically, the axial direction of the rod body 21 is arranged along the radial direction of the tool 1, one end of the rod body 21 is connected to the driving device 3, and the other end is connected to the impact head 22, so that the impact head 22 is driven to reciprocate under the drive of the driving device 3 to generate continuous impact force. The impact head 22 is made of 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 the stress more evenly, thereby avoiding excessive local stress and reducing damage to the impact head 22 or the knife 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 can make the impact force more evenly transmitted to the rock surface, reducing the lateral deviation of the impact rod 2 during the impact process; the spherical design of the impact head 22 is conducive to concentrating the axial impact force to the center of the impact head 22, thereby more efficiently transmitting kinetic energy to the rock, thereby further improving the rock breaking efficiency. In addition, compared with the sharp or angular design, the spherical impact head can evenly distribute the pressure when in contact with the rock, and is not easy to cause local 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 breaking rock, comprising: a cutter; a plurality of mounting holes provided on the cutter; the mounting holes are arranged along the radial extension of the cutter; a driving device, which is provided in the mounting hole; an impact rod, which is located in the mounting hole and connected to the driving device; the impact rod is used to extend out of and retract into the mounting hole under the drive of the driving device. In the present application, while breaking rock by the cutter, 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 driving device can be turned on, and the impact rod is driven by the driving 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 breaking rock.
