Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please see attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides an automatic pipe jacking machine for pipe jacking construction, comprising: The main frame 1 is made of high-strength steel and can withstand the thrust applied by the pipe jacking machine during operation; Propulsion module 2, including multiple push rods with a maximum thrust of 80 tons; The guide module 3 is arranged on both sides of the main frame 1 and is composed of a guide frame 31 and a base 32, so that the pipe jacking machine can maintain linear motion during the construction process; The tunneling head 4 is installed in front of the propulsion module 2, and includes a cutting tool 42 and a screw conveyor 43.

[0024] Automatic dynamic adjustment: The PLC controller in the control module can analyze the soil data such as hardness and moisture provided by the sensor in real time, and dynamically adjust the thrust of the propulsion module 2, the cutting speed of the tunneling head 4 and the power output of the power module 5 to ensure that the pipe jacking machine can operate stably under different geological conditions.

[0025] The guide module 3 ensures linear propulsion: The guide module 3 ensures that the pipe jacking machine can maintain linear propulsion under high resistance conditions through precise coordination between the guide frame 31 and the sliding bracket, thereby avoiding equipment deviation problems caused by uneven soil.

[0026] Significant improvement in reliability: High-strength main frame 1: The main frame 1 is made of high-strength steel and has extremely strong rigidity and durability.

[0027] Multi-push rod propulsion system: Propulsion module 2 adopts a distributed propulsion design with multiple push rods, with a thrust of up to 80 tons, which can evenly distribute the propulsion force and avoid equipment damage caused by excessive force at a single point.

[0028] Intelligent monitoring and early warning system: The equipment operating status is monitored in real time through pressure sensors, angle sensors and soil detection sensors. Once an abnormality occurs (such as excessive thrust, soil abnormality, etc.), the control module will immediately trigger an alarm and automatically adjust parameters to protect the equipment from damage.

The push rod part provides thrust through a hydraulic cylinder, and the pressure and stroke of the cylinder can be adjusted in real time through the control module to meet the needs of different soil types. The reasonable distribution of multiple push rods ensures that the pipe jacking machine is pushed more evenly and stably, avoiding the construction instability problem that may be caused by uneven local thrust.

[0031] The multiple push rod design of the propulsion module 2 provides an efficient and stable thrust source, which can adjust the thrust in different construction environments, ensure the smooth propulsion process of the pipe jacking machine, reduce thrust fluctuations during construction, and improve the accuracy and safety of construction.

[0034] The guide module 3 ensures that the pipe jacking machine always maintains a straight line during the construction process through precise guide design, reducing the risk of directional deviation and improving the accuracy and efficiency of construction. This design enables the pipe jacking machine to adapt to more complex construction environments, especially in underground pipeline construction, and has significant advantages in directional control under complex geological conditions.

[0048] Please see attached Figure 8 , an operation method of an automatic pipe jacking machine for pipe jacking construction, comprising the following steps: S1. Preparation: Transport the pipe jacking machine 1 to the construction site and inspect and clean the equipment; determine the starting and ending positions of the pipe jacking machine 1 and mark the construction path; install the guide rail 3 straight and firmly; S2. Equipment installation: Install the main frame 1, propulsion module 2, guide module 3, tunneling head 4 and power module 5 in sequence, so that each module is firmly connected and the equipment can operate normally; S3, control module connection: Install the control module 6, ensure that the PLC controller 61, the sensor 62 and the display 63 are correctly connected, and collect soil hardness, thrust and angle parameters through the sensor 62 to monitor the operation status of the equipment; S4. Equipment debugging: Start the power module 5 and check whether it works normally; start the control module 6 and check whether the sensor 62 and the display 63 feedback accurate equipment operation data; adjust the thrust and extension speed of multiple push rods in the propulsion module 2 according to the preset program, and debug the coordination of the propulsion module 2, the guide module 3, the tunneling head 4 and the power module 5; S5. Start jacking operation: Start the propulsion module 2, automatically adjust the thrust and extension speed of multiple push rods through the PLC controller 61, and start the jacking operation; monitor the data on the display 63 in real time; detect the soil hardness and moisture data in real time through the sensor 62, and adjust the cutting speed and thrust of the tunneling head 4; S6. Monitoring and adjustment: The operator can view the working status of the equipment in real time through the display 63 and make adjustments as needed; S7, end the operation: When the pipe jacking machine 1 is pushed to a predetermined position, the pushing operation is stopped and the power module 5 is turned off; the control module is turned off and the equipment operation data is saved.

[0049] In step S5, when push rod 1 21 is pushed, it pushes sliding bracket 1 22 to slide on the outer wall of guide frame 31, and when push rod 23 is pushed, it pushes sliding bracket 2 24 and tunneling head 4 to slide on the outer wall of guide frame 31 and the upper surface of base 32.

[0050] Specifically, S1. Preparation: Equipment cleaning and inspection: After transporting the pipe jacking machine 1 to the construction site, first clean the equipment thoroughly, especially the hydraulic system, electrical connectors, oil cylinder, sensors and other parts to prevent dust or debris accumulated during transportation from affecting the normal operation of the equipment. At the same time, check whether the hydraulic oil, fuel, batteries and other consumables are sufficient to ensure that the equipment is in the best working condition.

[0051] Through thorough cleaning and inspection, performance degradation caused by foreign matter or hydraulic failure during the initial operation of the equipment is avoided, the startup stability and working efficiency of the equipment are improved, and the probability of failure is reduced.

[0052] S2. Equipment installation: Module docking accuracy: During the installation process, the docking of each module needs to be adjusted with high-precision tools to ensure that the connection interface position is accurate and correct to avoid operation deviation caused by unstable connection. Especially when installing between the main frame 1 and the propulsion module 2 and the guide module 3, attention should be paid to the accuracy and stability of the docking to avoid deviation or looseness during the construction process.

[0053] Precise docking ensures the stability of the equipment after installation, enables the equipment to maintain a stable operating direction during construction, avoids performance fluctuations caused by installation errors, and enhances the adaptability and reliability of the pipe jacking machine under complex geological conditions.

[0054] S3, control module connection: Signal transmission and data synchronization: The control module 6 transmits data synchronously with each sensor 62 and the PLC controller 61 through a high-precision cable or wireless system. During signal transmission, anti-interference technology is used to avoid the influence of external electromagnetic interference on data collection and transmission, ensuring that the equipment can stably obtain various parameters such as soil hardness, thrust, angle, etc.

[0055] Anti-interference technology ensures the accuracy of data collection and transmission, and ensures that the equipment can maintain real-time monitoring and dynamic adjustment capabilities during high-load operations, thereby improving the stability of the automatic control system and the operating accuracy of the equipment.

[0056] S4. Equipment debugging: Load test in debugging: During the equipment debugging process, in addition to adjusting the thrust and extension speed of multiple push rods in the propulsion module 2, a load test is also required to simulate different geological conditions that may be encountered during the actual construction process to ensure that the equipment can still operate normally under the thrust limit. During the test, the PLC controller 61 automatically adjusts the propulsion speed and thrust to ensure that the equipment will not fail due to excessive load.

[0057] Beneficial effects: Load testing ensures that the equipment can still operate stably under high load conditions. It can simulate the changes brought about by different soil types during the construction process, identify potential problems in advance, improve the comprehensiveness and reliability of equipment debugging, and provide sufficient guarantee for subsequent construction.

[0058] S5. Start jacking operation: Automatic thrust adjustment: After the propulsion module 2 is started, the PLC controller 61 will automatically adjust the thrust and extension speed of the push rod according to the real-time feedback data of the soil. For example, when pushing in hard soil, the PLC controller will increase the thrust; in soft soil, the system will reduce the thrust and increase the propulsion speed, ensuring that the pipe jacking machine can maintain efficient operation under various soil conditions.

[0059] Automated thrust adjustment can optimize the propulsion strategy in real time according to soil conditions, avoiding damage to equipment or pipelines caused by excessive or insufficient thrust, and improving the adaptability and operating efficiency of the pipe jacking machine in complex geological environments.

[0060] S6. Monitoring and adjustment: Data feedback and real-time adjustment: Through the sensor 62, key parameters such as soil hardness, moisture, thrust, etc. are fed back to the control module 6 in real time. The operator can view these data in real time through the display 63 and can make fine adjustments through the control module when necessary. For example, if the sensor detects that the soil moisture is too high, which may cause increased equipment resistance, the operator can immediately adjust the cutting speed or thrust of the tunneling head 4 to reduce the burden on the equipment.

[0061] The real-time monitoring and feedback mechanism enables the operator to respond quickly to any changes during the construction process, adjust the operating parameters in time, and avoid the equipment operating under unsuitable soil conditions, thus ensuring the safety, efficiency of the operation and the long life of the equipment.

[0062] S7, end the operation: Run data storage and subsequent analysis: After the pipe jacking operation is completed, the control module 6 will store the equipment's operating data, including thrust, propulsion speed, soil parameters, working time, etc. These data will play an important role in subsequent equipment maintenance, performance analysis and optimization.

[0063] By storing and analyzing operating data, valuable information can be provided for the later maintenance and optimization of equipment, and possible equipment failures can be predicted in advance, thereby extending the service life of the equipment, reducing the failure rate, and improving construction efficiency.

[0064] Push rod operation in step S5: Coordination of the putter: In step S5, the coordinated work of push rod 1 21 and push rod 2 23 not only relies on the high efficiency of the hydraulic drive system, but also relies on the precise mechanical structure design. The push rod 1 21 and push rod 2 23 achieve stable relative motion through the sliding bracket 1 22 and the sliding bracket 2 24, ensuring that the push rod is evenly stressed during the advancement process, avoiding system instability caused by deflection.

[0065] The precise coordination of the push rods makes the advancement process smoother, avoids tilting or jamming caused by uneven thrust, ensures efficient advancement of the pipe jacking machine, and significantly improves the stability and accuracy during the construction process.
