Description

Technical Field

[0001] This invention relates to the technical field of slurry balance pipe jacking equipment, specifically a large-diameter, long-distance slurry balance pipe jacking machine. Background Technology

[0002] When laying municipal pipelines, to avoid traffic disruptions and increased construction costs caused by road excavation, it is often necessary to use a slurry-balanced pipe jacking machine to excavate underground pipeline channels. Patent application number CN201310351651.0 discloses a slurry-balanced pipe jacking machine. In unstable strata, when the excavation face is obstructed, slurry pressurization can be used to keep the excavation face stable, with less disturbance to the soil around the pipe being jacked and less ground settlement. Each spoke of the cutting disc has several pairs of cutting blades symmetrically arranged in a figure-eight shape on both sides, and some pairs of cutting blades are equipped with leading blades, so that the cutting disc can cut soil whether it rotates forward or backward. Meanwhile, the present invention also provides a central cutter at the center of the cutterhead panel, which protrudes significantly above the cutterhead surface. This allows the central cutter to drill ahead during construction, forming a pilot borehole to release the ground pressure at the center of the working face and prevent clay from adhering to the cutterhead panel. According to the disclosed technical solution, existing slurry balance pipe jacking equipment, when in use, is prone to sealing problems due to equipment movement during excavation, leading to slurry overflow and requiring replenishment. This is not conducive to maintaining slurry balance and increases energy consumption. On the other hand, when excavating soil, a large amount of slurry is often carried away, requiring extensive replenishment to maintain pressure at the excavation site, thus increasing the energy consumption for pumping slurry. Furthermore, during tunnel excavation, the breaking-ground operation of the pipe jacking machine can cause the connected pipes to be subjected to torque, which can easily cause pipe twisting or even damage, thus compromising pipeline safety.

[0009] Furthermore, a slot is provided on the outer side of the support sleeve, a sleeve is fitted inside the slot, one end of the sleeve is mounted on the inner side of the slot via a pivot, a guide rod is fitted inside the sleeve, one end of the guide rod extends to the outer side of the sleeve, and a support plate is welded to one end of the guide rod.

[0010] Furthermore, an insert plate is inserted into the inner side of the support plate, and a second motor is bolted to one side of the support plate. A lead screw is welded to the output shaft of the second motor, and one end of the lead screw passes through the support plate through a bearing and is threaded onto the inner side of the insert plate.

[0011] Furthermore, a second hydraulic pump is bolted to the inner side of the support sleeve. A connecting pipe is welded to the second hydraulic pump. One side of the second hydraulic pump is connected to the oil tank, and the other side of the second hydraulic pump is connected to the ferrule via the connecting pipe.

[0012] Furthermore, a jack is bolted to the inner side of the support sleeve, one end of which passes through the inner wall of the support sleeve and extends to the inner side of the slot, and the inner side of the slot sleeve is engaged with one end of the jack.

[0013] Furthermore, the interface is welded to one side of the support sleeve, the plug is opened on the inside of the interface, and a stop block is integrally formed on the inside of the interface. The stop blocks are evenly distributed on the inside of the interface, and pressure switches are installed on both sides of the stop block by bolts. The pressure switches are connected to the jack, hydraulic pump two and motor two by wires.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When using this large-diameter, long-distance slurry balance pipe jacking machine, the machine is used to excavate the tunnel and connect the pipes one by one to the interface. A hydraulic pump delivers hydraulic oil from the tank to the inside of a rubber ring. The rubber ring expands on the outside of the support sleeve and clamps onto the inner wall of the underground tunnel, using the pressure of the rubber ring for sealing. Simultaneously, during excavation, the inner cylinder moves inside the outer cylinder until it reaches the right end of the outer cylinder. Then, external equipment pushes the pipe to the inside of the tunnel, while simultaneously pushing the support sleeve and outer cylinder to the outside of the inner cylinder. The support sleeve and outer cylinder do not move during excavation, and the sealing rings ensure a seal, preventing slurry from leaking out through the gaps between the support sleeve and the tunnel. This effectively ensures slurry balance during pipe jacking operation, reduces the amount of slurry replenishment, and decreases energy consumption.

[0016] 2. When this large-diameter, long-distance slurry-water balance pipe jacking machine is in use, as the excavated soil enters the inner cylinder, the motor drives the rotating rod to rotate inside the inner cylinder via the screw plate, mixing the soil and slurry. With the push of the screw plate, the mixed soil and water are pushed to the inner side of the filter cylinder. Under the compression of the screw plate, the water is filtered through the filter cylinder and returns to the inner side of the inner cylinder. The soil is pushed to the inner side of the sleeve by the screw plate, and then the excavated soil is squeezed out through the outlet pipe with the thrust of the screw plate. Only a small amount of slurry-water needs to be added through the inlet pipe to achieve slurry-water balance, reducing the energy consumption required for adding slurry-water.

[0017] 3. When this large-diameter, long-distance slurry balance pipe jacking machine is in operation, the torque generated by the machine is transmitted from the inner cylinder to the outer cylinder. The outer cylinder, through the support sleeve, drives the interface to generate torque on the pipeline. The stop block inside the interface squeezes the pipeline through the pressure switch, thereby opening the pressure switch. The jack pushes the clamp to the outside of the support sleeve. Motor 2 pushes the insert plate out from the inside of the sleeve plate and inserts it into the inner wall of the channel through the lead screw. Hydraulic pump 2 pumps hydraulic oil to the inside of the clamp, and the hydraulic oil pushes the guide rod from the inside of the clamp outward. This causes the guide rod to push the inner wall of the channel through the sleeve plate and the insert plate, causing the support sleeve to generate reverse torque. When the torque generated by the pipe jacking machine is balanced with the torque generated by the guide rod pushing the sleeve plate and the insert plate, the pressure switch closes, thus ensuring the torque balance during the operation of the pipe jacking machine and preventing the torque from being transmitted to the pipeline. This effectively avoids the pipeline from twisting or even being damaged, ensuring the safe laying of the pipeline. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5This invention provides a technical solution: a large-diameter, long-distance slurry-balanced pipe jacking machine, comprising a pipe jacking machine 1 and a support sleeve 2. A pipe assembly is installed on one side of the support sleeve 2, the pipe assembly including an interface 4 and a socket 5. A slurry-balanced assembly is installed on the inner side of the support sleeve 2, the slurry-balanced assembly including an inlet pipe 6 and an outlet pipe 7. A sliding assembly is installed on the other side of the support sleeve 2, the sliding assembly including an outer cylinder 8 and an inner cylinder 9. A slurry-water delivery assembly is installed inside the inner cylinder 9, the slurry-water delivery assembly including a sleeve 10 and a pipe 11. A separation assembly is installed at one end of the sleeve 10. The assembly includes a filter cartridge 12 and a screw plate 14. An agitator is mounted on the screw plate 14, comprising a motor 13 and a rotating rod 15. A sealing assembly is mounted on the support sleeve 2, comprising a rubber ring 17 and a hydraulic pump 18. An outer cylinder 8 is integrally formed on the other side of the support sleeve 2. An inner cylinder 9 is welded to one side of the pipe jacking machine 1, and the pipe jacking machine 1 is connected to the inner cylinder 9. The outer side of the inner cylinder 9 is sealed to the inner side of the outer cylinder 8. One end of the outer cylinder 8 is integrally formed with a conical surface 16. An annular groove is formed on the outer side of the support sleeve 2, and the rubber ring 17 is engaged within the annular groove. An oil tank 20 is bolted to the inner side of the support sleeve 2. A hydraulic pump 18 is also bolted to the inner side of the support sleeve 2. One side of the hydraulic pump 18 is connected to the oil tank, and the other side is connected to a rubber ring 17 via a conduit. The rubber ring 17 is connected to the oil tank 20 via a solenoid valve 19. During operation, the pipe jacking machine 1 is used to excavate the tunnel, and the pipes are connected one by one to the rear of the interface 4. The hydraulic pump 18 pumps hydraulic oil from the oil tank 20 to the inner side of the rubber ring 17. The rubber ring 17 expands on the outer side of the support sleeve 2 and clamps the inner wall of the underground tunnel. The sealing operation is achieved by using the pressure of the rubber ring 17. At the same time, when the pipe jacking machine 1 is excavating, the inner cylinder 9 moves inside the outer cylinder 8 until the inner cylinder 9 moves to the right end of the outer cylinder 8. Then, the pipe is pushed to the inside of the channel by external equipment, and the support sleeve 2 and the outer cylinder 8 are pushed to the outside of the inner cylinder 9. The support sleeve 2 and the outer cylinder 8 do not move during the excavation operation. At the same time, the sealing ring 17 is used to seal the pipe, preventing mud and water from overflowing through the gap between the support sleeve 2 and the channel. This can effectively ensure the mud and water balance when the pipe jacking machine 1 is working, and reduce the amount of mud and water replenishment, thus reducing the energy consumption of the operation.

[0026] In this embodiment, a sealing plate 3 is welded to the inner wall of the inner cylinder 9. The inlet pipe 6 and outlet pipe 7 are both welded to one side of the sealing plate 3 and are connected to the inner cylinder 9. The sleeve 10 is bolted to the inner side of the inner cylinder 9 and is connected to the outlet pipe 7 via a connecting pipe 11. The motor 13 is bolted to the inner side of the inner cylinder 9. The filter cartridge 12 is welded to one end of the sleeve 10. One end of the screw plate 14 is clamped to the inner wall of the sleeve 10, and the other end of the screw plate 14 passes through the filter cartridge 12 and is keyed to the output shaft of the motor 13. The rotating rod 15 is welded to the outer side of the other end of the screw plate 14 and is located outside the filter cartridge 12. A slot is provided on the outer side of the support sleeve 2, and a retaining sleeve 23 is clamped inside the slot. One end of the retaining sleeve 23 is connected to the rotating shaft. Installed on the inner side of the slot, the inner side of the sleeve 23 is fitted with a guide rod 24, one end of the guide rod 24 extends to the outer side of the sleeve 23, and a support plate 25 is welded to one end of the guide rod 24. In use, when the soil excavated by the pipe jacking machine 1 enters the inner side of the inner cylinder 9, the motor 13 drives the rotating rod 15 to rotate inside the inner cylinder 9 through the screw plate 14, stirring the soil and mud water. With the push of the screw plate 14, the mixed soil and water are pushed to the inner side of the filter cylinder 12. Under the extrusion of the screw plate 14, the water is filtered through the filter cylinder 12 and returns to the inner side of the inner cylinder 9. The soil is pushed to the inner side of the sleeve 10 by the screw plate 14, and then the excavated soil is squeezed out through the outlet pipe 7 with the thrust of the screw plate 14. Only a small amount of mud water needs to be added through the inlet pipe 6 to achieve mud water balance, reducing the energy consumption required to add mud water.

[0027] In this embodiment, an insert plate 26 is secured to the inner side of the support plate 25. A second motor 27 is bolted to one side of the support plate 25. A lead screw 28 is welded to the output shaft of the second motor 27. One end of the lead screw 28 passes through the support plate 25 via a bearing and is threaded onto the inner side of the insert plate 26. A second hydraulic pump 21 is bolted to the inner side of the support sleeve 2. A connecting pipe 22 is welded to the second hydraulic pump 21. One side of the second hydraulic pump 21 is connected to the oil tank 20, and the other side of the second hydraulic pump 21 is connected to the insert plate 26 via the connecting pipe 22. The sleeve 23 is connected to the support sleeve 2. A jack 29 is bolted to the inner side of the support sleeve 2. One end of the jack 29 passes through the inner wall of the support sleeve 2 and extends to the inner side of the slot. The inner side of the sleeve 23 is engaged with one end of the jack 29. The interface 4 is welded to one side of the support sleeve 2. The insertion port 5 is opened on the inner side of the interface 4. A stop block 30 is integrally formed on the inner side of the interface 4. The stop blocks 30 are evenly distributed on the inner side of the interface 4. A pressure switch 31 is bolted to both sides of the stop block 30. The pressure switch 31 is electrically connected to the support sleeve 2. The line is connected to jack 29, hydraulic pump 21, and motor 27. During operation, the torque generated by the pipe jacking machine 1 is transmitted to the outer cylinder 8 through the inner cylinder 9. The outer cylinder 8 drives the interface 4 through the support sleeve 2 to generate torque on the pipe. The stop block 30 inside the interface 4 squeezes the pipe through the pressure switch 31, thereby opening the pressure switch 31. Jack 29 pushes the clamp 23 to the outside of the support sleeve 2. Motor 27 pushes the insert plate 26 out from the inside of the sleeve plate 25 and inserts it into the inner wall of the channel through the lead screw 28. Hydraulic pump 21 pumps hydraulic oil to... Hydraulic oil pushes the guide rod 24 outward from the inside of the ferrule 23, causing the guide rod 24 to push the inner wall of the channel through the sleeve plate 25 and the insert plate 26, thus generating a reverse torque in the support sleeve 2. When the torque generated by the pipe jacking machine 1 is balanced with the torque generated by the guide rod 24 pushing the sleeve plate 25 and the insert plate 26, the pressure switch 31 closes, thereby ensuring the torque balance when the pipe jacking machine 1 is working and preventing the torque from being transmitted to the pipeline. This effectively avoids the pipeline from twisting or even being damaged, ensuring the safe laying of the pipeline.

[0028] This large-diameter, long-distance slurry-balanced pipe jacking machine provides power to all electrical equipment via an external power supply. During operation, the pipe jacking machine 1 excavates the tunnel and connects the pipes one by one to the rear of the interface 4. Hydraulic pump 18 pumps hydraulic oil from the oil tank 20 to the inside of the rubber ring 17. The rubber ring 17 expands on the outside of the support sleeve 2 and clamps tightly against the inner wall of the underground tunnel, using the pressure of the rubber ring 17 for sealing. Simultaneously, while the pipe jacking machine 1 is excavating, the inner cylinder 9 moves inside the outer cylinder 8 until it reaches the right end of the outer cylinder 8. Then, external equipment pushes the pipe to the inside of the tunnel, and the support sleeve 2 is then installed. The sleeve 2 and outer cylinder 8 are pushed to the outside of the inner cylinder 9. The sleeve 2 and outer cylinder 8 do not move during excavation. At the same time, the sealing ring 17 is used to seal the surface, preventing mud and water from overflowing through the gap between the sleeve 2 and the channel. This effectively ensures the mud and water balance during the operation of the pipe jacking machine 1, reduces the amount of mud and water replenishment, and reduces working energy consumption. When the soil excavated by the pipe jacking machine 1 enters the inner side of the inner cylinder 9, the motor 13 drives the rotating rod 15 to rotate inside the inner cylinder 9 through the screw plate 14, mixing the soil and mud and water. With the push of the screw plate 14, the mixed soil and water are pushed to the inside of the filter cylinder 12. Under the pressure of the screw plate 14, the water is forced through. After filtration by the filter cylinder 12, the soil returns to the inner side of the inner cylinder 9. The soil is pushed to the inner side of the sleeve 10 by the screw plate 14, and then the excavated soil is squeezed out through the outlet pipe 7 by the thrust of the screw plate 14. Only a small amount of mud and water needs to be added through the inlet pipe 6 to achieve mud and water balance, reducing the energy consumption required for adding mud and water. During operation, the torque generated by the pipe jacking machine 1 is transmitted to the outer cylinder 8 through the inner cylinder 9. The outer cylinder 8 drives the interface 4 through the support sleeve 2 to generate torque on the pipe. The stop block 30 in the interface 4 squeezes the pipe through the pressure switch 31, thereby opening the pressure switch 31. The jack 29 pushes the clamp 23 to the outside of the support sleeve 2. The motor 27 drives the screw 28 to... Insert plate 26 is pushed out from the inside of sleeve plate 25 and inserted into the inner wall of the channel. Hydraulic pump 21 pumps hydraulic oil to the inside of clamp 23. The hydraulic oil pushes guide rod 24 outward from the inside of clamp 23, thereby causing guide rod 24 to push the inner wall of the channel through sleeve plate 25 and insert plate 26, causing support sleeve 2 to generate reverse torque. When the torque generated by the pipe jacking machine 1 is balanced with the torque generated by guide rod 24 pushing sleeve plate 25 and insert plate 26, pressure switch 31 is closed, thereby ensuring the torque balance when the pipe jacking machine 1 is working and preventing the torque from being transmitted to the pipeline, thus effectively avoiding the pipeline from twisting or even being damaged, and ensuring the safe laying of the pipeline.
