Especially the emergence of the pipe jacking construction technology, relying on the research and development of pipe jacking machine technology, has greatly improved the working efficiency and quality of tunnel excavation. The pipe jacking method of construction is to generate thrust in the working pit with the help of the thrust generated by the jacking equipment, overcome the friction between the pipeline and the surrounding soil, jack the pipeline into the soil according to the designed slope, and transport the soil away. In the existing pipe jacking construction technology, in order to ensure the pipe jacking construction direction, a deviation rectifying oil cylinder is required in the pipe jacking machine to adjust its construction direction. The existing deviation rectifying oil cylinder still adopts the traditional hydraulic oil cylinder design. Although this method can meet the usage requirements, its adjustment through the cylinder not only requires an external braking device to lock the tunneling part, but also has a low adjustment accuracy, and its practicability and economy need to be further improved.

Specific implementation mode
[0018] As Figures 1 to 4 shown, the deviation correction oil cylinder for the pipe jacking machine includes a cylinder body 2 and a locking frame 4. One end of the cylinder body 2 is sleeved with a sealing end sleeve 3. A sealing design is adopted between the sealing end sleeve 3 and the cylinder body 2. The other end of the sealing end sleeve 3 is fixedly connected with a locking frame 4. A brake 9 is arranged on the locking frame 4. A push-pull rod 12 is embedded in the cylinder body 2. A sealing design is adopted between the push-pull rod 12 and the sealing end sleeve 3. One end of the push-pull rod 12 is provided with a sensor frame 8. A displacement sensor 14 is embedded in the sensor frame 8. The displacement sensor 14 selects a laser ranging design. The sealing end sleeve 3 plays a role in sealing and limiting. The locking frame 4 plays a role in stable support. The brake 9 is convenient for braking the push-pull rod 12. The sensor frame 8 plays a role in stable support. The displacement sensor 14 is convenient for detecting the moving distance of the push-pull rod 12.
[0019] Among them, a first joint 10 and a second joint 11 are embedded in the cylinder body 2. One end of the cylinder body 2 far from the sealing end sleeve 3 is fixedly connected with a support frame 1. The first joint 10 and the second joint 11 are convenient for connecting the oil pipes. The support frame 1 plays a role in rotary support.
[0020] One side of the locking frame 4 is fixedly connected with a control box 5. The control box 5 is connected with the displacement sensor 14 through a wire. Through the above design, automatic control is convenient.
[0021] Once two process grooves 13 are opened at one end of the push-pull rod 12 close to the sensor frame 8. A connecting sleeve 6 is sleeved at the end of the push-pull rod 12 where the process grooves 13 are opened. The outer side of the connecting sleeve 6 adopts a regular hexagonal prism design. Through the above design, it is convenient to lock the connecting sleeve 6.
[0022] The other end of the connecting sleeve 6 is fixedly connected with a push-pull frame 7. A piston sleeve 16 is sleeved at the end of the push-pull rod 12 far from the connecting sleeve 6. The piston sleeve 16 and the push-pull rod 12 play a role in power transmission.
[0023] The brake 9 consists of a magnetic attraction frame 15, a brake frame 18 and a brake lining 17. The brake lining 17 is fixedly connected to the brake frame 18. A brake spring 23 is arranged between the brake frame 18 and the magnetic attraction frame 15. The brake lining 17 is made of a soft and wear-resistant material, and the brake spring 23 provides braking force for the device.
[0024] The brake 9 is connected to the locking frame 4 through a fixing screw 20. The brake frame 18 is connected to the magnetic attraction frame 15 through a guiding screw sleeve 19. The magnetic attraction frame 15 is provided with a mounting hole 24, a spring hole 25 and a coil groove 26. An electromagnetic coil 22 and a sealing layer 21 are embedded in the coil groove 26. A clearance fit is adopted between the brake frame 18 and the guiding screw sleeve 19. The guiding screw sleeve 19 is connected to the magnetic attraction frame 15 through a threaded connection. The sealing layer 21 is made of an insulating soft material.
[0025] Before use, the device is installed in a suitable position through the push-pull frame 7 and the support frame 1. The oil supply pipeline is connected through the first joint 10 and the second joint 11, and then it can be used. When in use, when pipe jacking deviation correction is required, the main machine sends a signal to the control box 5. The control box 5 supplies power to the electromagnetic coil 22. The magnetic attraction force generated by the electromagnetic coil 22 adsorbs the brake frame 18, compressing the brake spring 23, and then separating the brake lining 17 from the push-pull rod 12. In addition, the main machine controls the oil pump to increase the oil pressure on one side of the piston sleeve 16 in the oil cylinder body 2, pushing the piston sleeve 16 to move, and then pushing the push-pull rod 12 to move. During the movement of the push-pull rod 12, the displacement sensor 14 works, transmitting the detected moving distance of the push-pull rod 12 to the control box 5. The control box 5 judges the data. When the set distance is reached, the control box 5 cuts off the power supply to the electromagnetic coil 22, and the magnetic attraction force disappears. The brake spring 23 pushes the brake lining 17 to tightly press the push-pull rod 12 to lock and brake it. In addition, the control box 5 sends a signal to the main machine, and the main machine stops oil supply. The design of this new structure is reasonable, and it is convenient to install and use. Through the design of the brake 9, a braking function is added to the deviation correction oil cylinder, and the deviation correction position can be locked without an external braking device, with good practicability and economy. Through the design of the displacement sensor 14, the telescopic distance of the push-pull rod 12 can be accurately detected, and then the deviation correction angle can be accurately determined, greatly improving the pipe jacking accuracy of the device and further improving the practicability of the device.
