Description

Technical Field

[0001] The present invention relates to the technical field of mechanical shock absorption, and in particular to a shock absorption base for a tunnel boring machine and a shock absorption control method thereof. Background Art

[0002] The cutting stability of the tunnel boring machine is very critical. Adding a shock-absorbing base to the chassis of the tunnel boring machine can ensure the smooth progress of the tunnel boring operation. In the complex and changeable underground environment, it effectively absorbs and disperses the vibration and impact generated during the tunnel boring process through its unique design and materials. The excellent performance of the shock-absorbing base not only significantly improves the stability and service life of the tunnel boring machine, but also greatly reduces the noise level during the operation of the equipment, providing a more comfortable working environment for operators. In addition, by reducing the impact of vibration on precision parts, it also indirectly improves the machining accuracy and efficiency of the tunnel boring machine, which plays an irreplaceable role in ensuring the smooth progress of tunnel boring operations and improving overall operating efficiency.

[0003] In the prior art, the operating stability of the tunnel boring machine under complex geological conditions is often challenged, especially when operating in hard rock or unstable strata. The vibration of the machine body not only affects the tunneling efficiency, but may also pose a threat to the safety of equipment and personnel. For the tunnel boring machine shock-absorbing base and its shock-absorbing control method, the corresponding lifting and lowering actions are performed according to the tunnel boring machine working conditions and the support force given by the ground during operation. Due to the rigidity of the shock-absorbing technology program and the lack of perception of the surrounding conditions, once an emergency occurs, the task cannot be continued, resulting in poor shock absorption effect. When the tunnel boring machine is used to cut the coal wall, it is equipped with a base to fix it. The tunnel boring machine will inevitably shake during the operation, and at the same time, the bottom support of the tunnel boring machine will be affected, causing the whole machine to lack stability during operation.

[0004] Therefore, it is necessary to develop a vibration-absorbing base for a tunnel boring machine and a vibration-absorbing control method thereof to solve the above-mentioned problems. Summary of the invention

[0014] The tunnel boring machine vibration-absorbing base also includes a control system, which includes a controller and a sensing module, and the sensing module is used to collect working face information of the tunnel boring working face and obtain ground rail trajectory information; The perception module includes a camera unit, an inertial navigation unit and a ranging radar unit; The connecting ends of the first hydraulic cylinder and the second hydraulic cylinder are both provided with a hydraulic drive mechanism for providing kinetic energy; the input end and the output end of the controller are electrically connected to an A / D converter and a D / A converter respectively; the distance measuring sensor, the pressure sensor and the sensing module are all electrically connected to the A / D converter; and the alarm, the drive motor and the hydraulic drive mechanism are all electrically connected to the D / A converter.

[0015] A vibration reduction control method for a vibration reduction base of a tunnel boring machine comprises the following steps: S1. Before the cantilevered roadheader stops moving for cutting, a command to lower the roadheader's shock-absorbing base is issued; S2. The controller controls the synchronous extension of multiple second hydraulic cylinders through the hydraulic drive mechanism, so that the bottom end of the shock-absorbing base of the tunnel boring machine contacts the ground. With the cooperation of the pressure sensor, after the feedback pressure information reaches the appropriate range, the guide mechanism is installed in combination with the ground rail to guide the movement; S3, the cantilever tunneling machine starts drilling or swaying operation. During the process, the pressure sensor continuously senses and feeds back pressure information. The controller controls the synchronous extension and retraction of multiple first hydraulic cylinders through the hydraulic drive mechanism according to the pressure fluctuation value sensed by the pressure sensor, and further cooperates with the distance measuring sensor and the hydraulic shock absorber for secondary lifting and lowering operation for adjustment; S4. If the pressure sensed by the pressure sensor again appears in an abnormal range, the controller controls the alarm to send out an alarm signal, and communicates with the control host of the cantilever tunneling machine, cuts off the corresponding shock absorbing base operation system and gradually shuts down the cantilever tunneling machine; S5. Check the cause of the fault and perform troubleshooting and maintenance. After maintenance, return to S1 and continue to start operation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The tunnel boring machine shock-absorbing base is installed at the bottom of the cantilever tunnel boring machine. When working, its bottom end is lowered to the ground. The shaking generated during operation is absorbed by the sliding of the shock-absorbing mechanism, and the height can be adjusted in real time according to the actual working conditions. It cooperates with the guide mechanism and the ground rail for guidance. When the buffer spring is compressed, the force generated is partially offset, so that the shaking amplitude generated during the operation of the tunnel boring machine is reduced, thereby increasing the stability of the tunnel boring machine on the base. When the supporting force at the bottom of the shock-absorbing base is insufficient, it is raised and lowered to ensure the shock-absorbing effect of the shock-absorbing base, and the stability and safety are significantly improved.
