Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, in particular to a tool wear monitoring device for a composite stratum shield machine. Background Art

[0002] Shield tunnel boring machines (TBMs) are large-scale equipment used in tunnel and subway construction. The cutterhead drives the cutting tools, with diameters ranging from 6.2 to 6.4 meters for subway construction. Cutting tools are key components in tunneling and are also the most susceptible to wear and failure. Tool wear primarily refers to wear on the blade and cutter body. This wear not only prevents tunneling but also endangers personnel. Real-time monitoring of tool wear during construction has become a core technology that international tunneling equipment manufacturers are competing to develop.

[0003] There are currently two methods for inspecting cutters: one is for construction workers to enter the cutterhead through a pressure chamber when the machine is stopped to inspect and perform operations; the other is for construction workers to enter the cutterhead by digging a vertical shaft or side shaft in front of the cutterhead tool to perform the same operations. The latter method is extremely costly, and the former inspection method, while intuitive, is also risky. The main manifestations are: (1) shutdown may cause major accidents due to instability of the surrounding soil; (2) during the inspection or cutter replacement process, only specially trained personnel can withstand the 2-5 times atmospheric pressure in the pressure chamber. This problem is particularly prominent when construction is in special areas such as rivers and important buildings, as it is impossible to timely judge the wear status of the cutterhead.

[0004] However, the existing composite stratum shield machine tool wear monitoring device has the following shortcomings:

[0005] 1) Traditional tool wear monitoring relies heavily on regular manual inspections, which have problems such as long monitoring cycles and data lags. This makes it difficult to reflect tool status in real time, and failure to replace worn tools in a timely manner can easily lead to decreased construction efficiency or equipment failure. Debris cleaning usually relies on manual labor or simple mechanical structures, which can lead to incomplete cleaning and residual debris that interferes with subsequent monitoring. The equipment structure is mostly fixed and requires complete disassembly for maintenance, which is cumbersome and time-consuming, impacting project progress.

[0006] 2) Traditional monitoring devices mostly use an integrated rigid cover structure, lacking layered sealing and sliding connection design, which makes it easy for external impurities to penetrate into key component areas, corroding or clogging sensors, and reducing monitoring accuracy; the cover and internal components are mostly fixedly connected, and the entire cover needs to be disassembled for maintenance, which is time-consuming and labor-intensive and can easily damage the sealing structure.

[0007] 3) Traditional collection mechanisms mostly rely on unguided direct pulling methods. The collection box is prone to getting stuck due to track deviation or excessive friction, resulting in low cleaning efficiency and time-consuming and labor-intensive. The lack of a positioning device makes the collection box's reset accuracy insufficient. Long-term use can easily lead to problems such as loose sealing and debris residue. The operating interface is not equipped with a dedicated pull handle and buffer protection structure, resulting in inconvenient operation and risks of easy damage to components during maintenance.

[0008] Therefore, we proposed a composite stratum shield machine tool wear monitoring device to solve the above problems. Summary of the Invention

[0041] The effects achieved by the entire embodiment 1 are: significantly improved operational convenience and detection efficiency; the shell mechanism 1 cleverly adopts a symmetrical bracket 102 and an advanced hydraulic support system, which enhances the stability of the overall structure and ensures the stability of the equipment during operation; the dual rotation structure of the rotating ring 201 and the rotating table 202, combined with the precise gear 207 tooth block transmission system, achieves precise positioning and efficient power transmission of the equipment, ensuring the accuracy of each action; the cutter head mechanism 3 integrates a detachable rotary cutter 306, a high-sensitivity sensor 307 and a multi-function detector 308, combined with the quick-release design of the support plate 303 with a slot and the cover plate 309, which effectively guarantees the cutting accuracy , and greatly facilitates the maintenance and replacement of the equipment, and improves work efficiency.

[0042] Example 2, according to Figure 1 、 Figure 8 、 Figure 9 As shown, a fixing groove 317 is provided inside the cover 309, a clamping pad 318 is provided inside the fixing groove 317, a connecting plate 319 is fixedly installed on the side of the clamping pad 318, a protective cover 320 is fixedly installed on the surface of the connecting plate 319, a groove B321 is provided on the surface of the protective cover 320, a fixing rod 322 is fixedly installed in the middle of the groove B321, the connecting plates 319 are evenly distributed on the back of the protective cover 320, the connecting plates 319 and the cover 309 are slidingly connected, the clamping pad 318 and the cover 309 are slidingly connected, the fixing rod 322 is fixed to the center of the protective cover 320 through the groove B321, and the protective cover 320 and the cover 309 are slidingly connected.

[0043] The effect achieved by the entire embodiment 2 is as follows: in terms of deeply optimizing the maintenance convenience and overall structural stability of the equipment, we have specially designed a sliding connection method between the protective cover 320 and the cover plate 309, and cleverly used the groove B321 for precise positioning, combined with the evenly distributed connecting plates 319 and the fixing rod 322 located in the center, thereby ensuring accurate alignment and firm fixing effect during the installation process, effectively preventing the displacement problem that may occur in the use of the protective cover 320, and greatly improving the safety and stability of the equipment. The linkage sliding structure adopted between the card pad 318 and the connecting plate 319 greatly simplifies the disassembly and assembly process. When performing maintenance or replacement, the operation can be completed easily and quickly without the aid of any tools, reducing the difficulty of maintenance, and significantly reducing the wear of components caused by frequent operations, thereby effectively extending the service life of the components and significantly improving operational efficiency.

[0044] Example 3, according to Figure 1-Figure 4 As shown, a guide rail 5 is fixedly installed on the top of the base plate 103, a fixed block 6 is fixedly installed on the bottom end of the collecting box 407, a rotating rod 7 is fixedly installed on the right side of the fixed block 6, a positioning plate 8 is fixedly installed on the surface of the rotating rod 7, a rotating wheel 9 is fixedly installed on the right side of the positioning plate 8, a pull handle 10 is fixedly installed on the back of the collecting box 407, a protective pad 11 is fixedly installed on the surface of the collecting box 407, the guide rails 5 are symmetrically distributed at the left and right ends of the top of the base plate 103, the fixed blocks 6 are evenly distributed at the four corners of the bottom end of the collecting box 407, the positioning plate 8 and the guide rail 5 are rotatably connected, and the rotating wheel 9 and the guide rail 5 are rotatably connected.

[0045] The effect achieved by the entire embodiment 3 is as follows: on the basis of in-depth optimization of mobile stability and operational convenience, a symmetrically distributed guide rail 5 system and four-corner fixing blocks 6 are carefully designed. The two cooperate with each other to form a dual positioning mechanism to ensure the stability and accuracy of the equipment. By cleverly combining the linkage mechanism of the rotating rod 7, the positioning plate 8 and the rotating wheel 9, the collection box 407 is successfully slid smoothly on the guide rail 5, and supports flexible steering during the sliding process, which not only improves the flexibility of operation, but also significantly reduces the risk of jamming, making the entire operation process smoother. The design of the handle 10 and the protective pad 11 fully considers the dual needs of ergonomics and durability. The design of the handle 10 has been carefully optimized, which greatly improves the pulling efficiency and makes the operation more labor-saving and convenient. The addition of the protective pad 11 effectively prevents possible collisions and wear during movement, thereby extending the service life of the equipment. The overall structure adopts a modular rotating connection design to ensure that the collection box 407 can be accurately positioned in each use, simplifying the maintenance and replacement process.

[0046] The working principle of the entire equipment is as follows: when in use, the shell mechanism 1 is first installed at the place where construction is required. The hydraulic cylinder 105 on the back of the side plate 104 first acts to apply dynamic supporting force to the shell body 101 through the support pad 106 to adapt to different geological conditions and enable the shell body 101 to move forward. Then the motor 206 at the top of the bracket 102 is started and drives the gear 207 to rotate, so that the gear block B208 engages with the gear block A204 to transmit torque to the convex ring 203, and drives the rotating table 202 to rotate together, and then drives the rotating ring 201 and the fixed plate 301 evenly distributed on the surface to rotate synchronously, thereby completing the use of the rotating mechanism 2. During use, the motor 206 is fixed to the top of the bracket 102 by the base 205 , it can achieve a better fixing effect. When the rotating mechanism 2 rotates, the cutter head mechanism 3 also rotates. During the operation, the rotary cutter 306 rotates inside the fixed plate 301 through the groove A302, and rotates on the surface of the cover plate 309 through the rotating groove 313, and rotates in the middle of the support plate 303 through the rotating rod 305. At this time, the rotating rod 305 rotates inside the support plate 303 through the card slot A304, and rotates inside the support block 311 through the card slot B312, thereby completing the effect of the rotary cutter 306 cutting rock and soil. During use, the sensor 307 continuously collects tool wear data through the detector 308 and performs real-time analysis. The debris generated by cutting enters through the baffle A401 and baffle B402. The collecting mechanism 4 is guided to the guide plate 405 inside the discharge hole 404 and slides into the collecting box 407 along the inclined plate 406. When the collection is completed, the handle 10 can be held and pulled backward to make the positioning plate 8 and the rotating wheel 9 rotate the knife 306 on the side of the fixed block 6 through the rotating rod 7 and slide out of the top of the bottom plate 103 to complete the effect of cleaning the debris. During use, the collecting box 407 is accurately reset by the rotating wheel 9 and the positioning plate 8 on the guide rail 5. During the resetting process, the protective pad 11 can protect the collecting box 407. When maintenance is required, the operator can also pull the collecting box 407 out of the guide rail 5 by the handle 10. At the same time, when removing the cover 309, first lift it toward the protective cover 320 through the fixing rod 322 inside the groove B321. When the cover 320 slides out of the interior of the cover plate 309 through the storage slot 314, it drives the connecting plate 319 and the clamping pad 318 to slide upward. When the clamping pad 318 slides out of the interior of the fixing slot 317 and the connecting plate 319 slides out of the interior of the protrusion 315, the cover 320 can be removed. At this time, the bolt 323 is rotated through the tool slot 324 to make the threaded rod 325 rotate upward inside the fixing plate 301 through the threaded slot 327. When the threaded rod 325 is completely rotated out of the interior of the fixing plate 301 through the threaded slot 327 and rotated out of the interior of the protrusion 315 through the installation slot 316, the cover plate 309 is pulled upward to make the protrusion 315 slide out of the interior of the fixing plate 301 through the positioning slot 326, thereby completing the removal of the cover plate 309 and the clamping plate 310.The inspection channel can be quickly opened by sliding the protrusion 315 in the positioning groove 326. After the rotary cutter 306 is replaced or the sensor 307 is calibrated, the operation can be resumed by reassembling. When the interior of the collecting mechanism 4 needs to be cleaned, it can be cleaned through the maintenance port 403.
