Description

Technical Field

[0001] This utility model belongs to the technical field of underground pipeline construction equipment, specifically, it relates to an intelligent guiding and correction device for slurry-water balance pipe jacking in complex strata. Background Technology

[0002] Slurry-balanced pipe jacking is a mechanical, automated pipe jacking construction method. It involves cutting the soil across its entire cross-section and using slurry pressure to balance soil and groundwater pressure. Slurry is used as the medium for transporting excavated soil. The advantages of this method include a wide range of applicable geological conditions, effective maintenance of the excavation face stability, minimal disturbance to the surrounding soil, and minimal ground settlement. Furthermore, the working environment within the working pit is relatively good, and operations are safer because it uses slurry to transport excavated soil, eliminating the need for dangerous tasks such as moving and hoisting earth.

[0003] The attitude sensors (such as gyroscopes) and torque sensors used in the correction and adjustment process are installed on the head of the pipe jacking machine. However, the installation and disassembly process of the attitude sensors is complicated. They are usually installed and disassembled by bolts, which requires special tools. The maintenance or replacement in the later stage is time-consuming and seriously affects the construction progress.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem of installing attitude sensors (such as gyroscopes) and torque sensors on the pipe jacking machine head during correction and alignment, which involves complex installation and removal processes and typically rely on bolts, requiring specialized tools and resulting in time-consuming maintenance or replacement, thus significantly impacting construction progress, this utility model adopts the following basic concept:

[0006] A smart guiding and correction device for jacking pipe in complex formations with slurry balance includes a jacking machine and a cutterhead disposed at one end of the jacking machine. The cutterhead is equipped with a disassembly and assembly mechanism and a protective mechanism.

[0007] The disassembly and assembly mechanism includes a mounting slot formed on the cutter head, a mounting post provided on the inner wall of the mounting slot, a positioning rod provided on the mounting post, and an attitude sensor provided on the mounting post. The positioning rod is used to quickly disassemble and assemble the mounting post and the attitude sensor.

[0008] The protective mechanism includes a protective cover mounted on a mounting post, which is used to protect the attitude sensor.

[0009] In a preferred embodiment of this utility model, the disassembly and assembly mechanism includes a limiting slide groove formed on the inner wall of the mounting groove, a positioning hole formed on the inner wall of the limiting slide groove, a limiting slide bar connected to the outer wall of the mounting column, a sliding hole formed on the outer wall of the limiting slide bar, a spring connected to the inner wall of the sliding hole, the end of the spring away from the inner wall of the sliding hole being connected to one end of the positioning rod, and a lever connected to the outer wall of the positioning rod.

[0010] In a preferred embodiment of the present invention, the disassembly and assembly mechanism includes a rotating shaft rotatably mounted on a mounting column, the outer wall of the rotating shaft being connected to one side of the outer wall of the protective cover, and a magnetic block being connected to one end of the outer wall of the mounting column located on one side of the rotating shaft.

[0011] In a preferred embodiment of this utility model, there are two limiting slide bars, which are distributed on both sides of the outer wall of the mounting column in a left-right symmetrical structure.

[0012] In a preferred embodiment of this utility model, the outer wall of the positioning rod is fitted to the inner wall of the positioning hole, and the outer wall of the limiting slide is fitted to the inner wall of the limiting slide groove.

[0013] In a preferred embodiment of this utility model, the size of the protective cover is equal to the outer wall of one end of the mounting post.

[0014] In a preferred embodiment of this utility model, the protective cover is made of a magnetically connectable metal material.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention utilizes a lever to retract a positioning rod, which is then inserted into the inner walls of the mounting groove and the limiting slot, respectively, to initially limit the mounting column. Releasing the lever allows the spring to return the positioning rod to its original position, thus locking it into the inner wall of the positioning hole and completing the installation of the attitude sensor. This allows for quick assembly and disassembly of the mounting column, improving efficiency and minimizing disruption to subsequent construction work.

[0017] This invention uses a protective cover to cover and protect the mounting column and attitude sensor, preventing mud from accumulating on the sensor's detection surface and avoiding direct contact between mud and sand, which can easily cause wear on the sensor components. Both of these factors can lead to attitude data drift and ultimately affect the accuracy of correction.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 4 As shown, a smart guide and correction device for slurry balance pipe jacking in complex formations includes a pipe jacking machine 1 and a cutterhead 2 disposed at one end of the pipe jacking machine 1. The cutterhead 2 is equipped with a disassembly and assembly mechanism 31 and a protective mechanism 32. The disassembly and assembly mechanism 31 includes an installation groove 311 opened on the cutterhead 2. An installation column 313 is provided on the inner wall of the installation groove 311. A positioning rod 317 is provided on the installation column 313. An attitude sensor 319 is provided on the installation column 313. The positioning rod 317 is used for quick disassembly and assembly of the installation column 313 and the attitude sensor 319. The protective mechanism 32 includes a protective cover 322 disposed on the installation column 313. The protective cover 322 is used to protect the attitude sensor 319.

[0027] Furthermore, the disassembly and assembly mechanism 31 includes a limiting slide groove 312 formed on the inner wall of the mounting groove 311. The inner wall of the limiting slide groove 312 is provided with a positioning hole 315. The outer wall of the mounting column 313 is connected to a limiting slide bar 314. The outer wall of the limiting slide bar 314 is provided with a sliding hole. The inner wall of the sliding hole is connected to a spring 316. The end of the spring 316 away from the inner wall of the sliding hole is connected to one end of the positioning rod 317. The outer wall of the positioning rod 317 is connected to a lever plate 318.

[0028] Furthermore, there are two limiting slide bars 314, which are distributed symmetrically on both sides of the outer wall of the mounting post 313. The limiting slide bars 314 on the left and right sides can provide uniform support for the mounting post 313, thereby further improving the installation stability of the attitude sensor 319.

[0029] Furthermore, the outer wall of the positioning rod 317 is properly fitted to the inner wall of the positioning hole 315, and the outer wall of the limiting slide 314 is properly fitted to the inner wall of the limiting slide groove 312. This improves the installation stability of the mounting post 313 and the attitude sensor 319, thereby improving the accuracy of subsequent detection.

[0030] The protective mechanism 32 includes a rotating shaft 321 rotatably mounted on a mounting post 313. The outer wall of the rotating shaft 321 is connected to one side of the outer wall of the protective cover 322. A magnetic block 323 is connected to one side of the outer wall of the mounting post 313 located on the rotating shaft 321.

[0031] Furthermore, the size of the protective cover 322 is equal to the outer wall of one end of the mounting post 313, so that the attitude sensor 319 can be completely covered and protected, thereby reducing damage to the attitude sensor 319 and reducing the impact on data detection.

[0032] Furthermore, the protective cover 322 is made of a magnetically connectable metal material, which allows the protective cover 322 to be magnetically connected to the magnetic block 323, thereby ensuring stability during the protection process.

[0033] The implementation principle of the intelligent guidance and correction device for jacking pipe in complex formations according to this embodiment is as follows: When the attitude sensor 319 needs to be installed, firstly, the two side plates 318 are moved, causing the side plates 318 to move the two side positioning rods 317 towards the center position of the mounting column 313. At this time, the outer wall of the positioning rod 317 will retract into the interior of the limiting slide bar 314. At the same time, the spring 316 will be squeezed and compressed during the movement of the positioning rod 317. Then, the limiting slide bars 314 on both sides of the mounting column 313 are aligned with the limiting slide grooves 312 opened in the inner wall of the mounting groove 311. Then, the mounting column 313 is inserted. On the inner wall of the mounting groove 311, the limiting slide bar 314 is inserted into the inner wall of the limiting slide groove 312. The limiting slide groove 312 and the limiting slide bar 314 can perform preliminary limiting installation of the mounting post 313. After the mounting post 313 is inserted into the inner wall of the mounting groove 311, the lever 318 can be released. At this time, the spring 316 will rebound and reset, thereby pushing the positioning rod 317 to reset and move. At this time, the outer wall of the positioning rod 317 will be inserted into the positioning hole 315 opened inside the limiting slide groove 312. This can limit the installation of the mounting post 313, thereby ensuring the stability of the installation of the mounting post 313.

[0034] During disassembly, simply move the levers 318 on both sides to disengage the outer wall of the positioning rod 317 from the inner wall of the positioning hole 315 to release the installation limit on the mounting post 313. Then, remove the mounting post 313 from the inner wall of the mounting slot 311 to complete the disassembly. With the disassembly and assembly of the mounting post 313, the attitude sensor 319 can be disassembled and assembled. The positioning rods 317 on both sides can be used to complete the quick disassembly and assembly, so that no external tools are needed to assist in disassembly and assembly, thereby improving the efficiency of disassembly, assembly and maintenance and avoiding the impact on subsequent construction.

[0035] Before disassembly and assembly, the protective cover 322 needs to be pushed outward to disengage it from the magnetic connection between the protective cover 322 and the magnetic block 323. This allows the protective cover 322 to be opened for disassembly and assembly. The protective cover 322 prevents mud from accumulating on the detection surface of the attitude sensor 319 and avoids direct contact between mud and sand and the attitude sensor 319, which can easily cause wear on the components. Both of these factors can lead to attitude data drift and ultimately affect the accuracy of correction.
