Description

Technical Field

[0001] The utility model relates to the technical field of TBM tool changing equipment, in particular to a TBM tool changing device for an inclined well. Background Art

[0002] With the rapid growth in the scale and pace of domestic pumped-storage power station construction, problems and shortcomings in traditional construction methods have gradually become apparent during the construction process. This is particularly true in the construction of long, multi-stage, and extremely steeply inclined sections of water transfer tunnels, where existing safety and progress issues have become a major challenge. In the construction of pumped-storage power stations, the use of inclined shaft TBMs (tunnel boring machines) can significantly improve construction efficiency, achieving "mechanized replacement of personnel, automated efficiency improvement, and intelligent construction." During TBM excavation, cutting tools frequently need to be replaced to ensure efficient excavation. In a TBM, the cutterhead is equipped with multiple cutter boxes, each containing a cutting tool. To replace a tool, the damaged cutter must be removed from the box and replaced with a new one. Existing techniques often use a hoisting mechanism to raise the cutter to the same height as the box, supplemented by manual insertion of the cutter into the box. For example, Chinese patent publication CN219546501U discloses a shield cutter hoisting structure. While this structure can adjust the distance between the fixed and movable clamping plates according to the cutter size, and uses clamping and limiting to prevent the cutter from falling off during suspended installation due to loose fixation, in inclined shafts, due to the inclined arrangement of the cutterhead, workers need to push the cutter upward along the inclination of the cutterhead to complete the installation process. This is labor-intensive and poses significant safety risks. Utility Model Content

[0029] Example 1

[0030] Figures 1 to 7An embodiment of the inclined shaft TBM tool changing device of the utility model is shown. The inclined shaft TBM tool changing device of this embodiment includes a first lifting mechanism 1, a second lifting mechanism 2, a guide assembly 3 and a lifting mechanism 4. The guide assembly 3 is installed at the bottom of the tool box 51 and is used to tilt and guide the tool 6 along the tilting direction of the tool box 51. The first lifting mechanism 1 is detachably installed on the tool box 51 and is used to lift the tool 6 along the tilting direction of the tool box 51. The second lifting mechanism 2 is installed on the cutter disc 5 and is used to lift the tool 6 in the vertical direction to cooperate with the first lifting mechanism 1 to lift the tool 6 into or out of the guide assembly 3. The lifting mechanism 4 is detachably installed on the guide assembly 3 and is used to lift the tool 6 into the tool box 51.

[0031] The inclined shaft TBM tool changing device of this embodiment has a guide assembly 3 installed at the bottom of the tool box 51. When installing the tool 6, the first lifting mechanism 1 and the second lifting mechanism 2 can lift the tool 6 together. During the lifting process, the tool 6 can move obliquely, which facilitates the lifting of the tool 6 into the guide assembly 3. After the tool 6 is lifted into the guide assembly 3, the second lifting mechanism 2 no longer participates in the lifting. The first lifting mechanism 1 continues to lift the tool 6 for a distance along the inclined direction of the tool box 51 to facilitate the installation of the lifting mechanism 4 on the guide assembly 3. After the lifting mechanism 4 is installed, the first lifting mechanism 1 is removed, and the lifting mechanism 4 lifts the tool 6, causing the tool 6 to move upward along the guide direction of the guide assembly 3 until the tool 6 is installed in the tool box 51. During the installation of the tool 6, there is no need for workers to push the tool 6 upward, which reduces the labor intensity and safety risks of workers and improves the safety of the tool 6 installation process. In addition, the first lifting mechanism 1 is detachably connected to the tool box 51 , and the jacking mechanism 4 is detachably connected to the guide assembly 3 , which improves the utilization efficiency of the first lifting mechanism 1 and the jacking mechanism 4 and saves layout costs.

[0032] See Figure 2 Furthermore, in this embodiment, the guide assembly 3 includes a guide frame 31 and a guide channel 32 provided within the guide frame 31. The top end of the guide frame 31 is detachably connected to the bottom end of the tool box 51, and the lifting mechanism 4 is detachably mounted on the bottom of the guide channel 32. This improves the utilization efficiency of the guide frame 31 and saves installation costs.

[0033] See Figure 4 、 Figure 6 and Figure 7 Furthermore, in this embodiment, slots 33 are provided on both sides of the guide channel 32, and the two sides of the lifting mechanism 4 are respectively inserted into the slots 33 on both sides of the guide channel 32. Specifically, the extending direction of the slots 33 is perpendicular to the central axis of the guide channel 32. The slots 33 have a simple structure, and installation and disassembly can be completed by simply inserting the two sides of the lifting mechanism 4 into the slots 33, making assembly and disassembly quick and convenient.

[0034] See Figure 2 、 Figure 4 、 Figure 6 and Figure 7 Furthermore, in this embodiment, the guide frame 31 includes a plurality of guide rods 311 and a mounting plate 312 disposed at the top of the guide rods 311. The mounting plate 312 is connected to the bottom end of the tool box 51 via bolts. The plurality of guide rods 311 are symmetrically mounted on both sides of the bottom end of the tool box 51, forming a guide channel 32 between the plurality of guide rods 311. The slots 33 are disposed on the guide rods 311. Specifically, two guide rods 311 are connected to each side of the bottom end of the tool box 51, which helps ensure the stability of the movement of the tool 6 within the guide channel 32. Of course, in other embodiments, the guide rods 311 may be arranged in other numbers depending on the weight of the tool 6.

[0035] See Figures 2 to 6 Furthermore, in this embodiment, the bottom end of each guide rod 311 is hinged with an extension rod 34, and a mounting bracket 313 is fixed to the outside of the guide rod 311. A telescopic rod 35 is connected between the mounting bracket 313 and the extension rod 34 located on the same guide rod 311, and the two ends of the telescopic rod 35 are hinged to the mounting bracket 313 and the extension rod 34 respectively. A guide corridor is formed between each extension rod 34, and the guide corridor is connected to the guide channel 32. After the second lifting mechanism 2 lifts the tool 6 into the guide corridor, it no longer participates in the lifting of the tool 6. The first lifting mechanism 1 continues to lift the tool 6 and drives the tool 6 to move into the guide channel 32, reducing the lifting height when the first lifting mechanism 1 and the second lifting mechanism 2 jointly lift the tool 6, thereby improving the safety of the tool 6 during lifting; the extension rod 34 is hinged to the guide rod 311, and the telescopic rod 35 can be telescopically controlled to rotate outward around the hinge point with the guide rod 311. When the first lifting mechanism 1 and the second lifting mechanism 2 jointly lift the tool 6, each extension rod 34 can be rotated outward to leave enough space to facilitate the lifting of the tool 6. During the resetting process of the extension rod 34, the position of the tool 6 can be adjusted at any time to ensure that the tool 6 can be smoothly guided into the tool box 51 after the extension rod 34 is reset.

[0036] See Figure 2 、 Figure 4 and Figure 6Furthermore, in this embodiment, the telescopic rod 35 includes a first connecting rod 351 and a second connecting rod 352 that are movably connected. The first connecting rod 351 is hinged to the mounting bracket 313, and the second connecting rod 352 is hinged to the extension rod 34. A locking member 353 is provided between the first connecting rod 351 and the second connecting rod 352 for locking the two. The first connecting rod 351 and the second connecting rod 352 have a simple structure and are reliable in use. After the telescopic rod 35 is reset, the locking member 353 locks the first connecting rod 351 and the second connecting rod 352, which helps ensure the stability of the tool 6 as it rises along the extension rod 34. Specifically, the first connecting rod 351 is provided with a first locking hole, and the second connecting rod 352 is provided with multiple second locking holes along its length. The locking member 353 is a bolt that is inserted into the first and second locking holes to lock the first and second connecting rods 351 and 352.

[0037] Furthermore, the extension rod 34 is detachably connected to the guide rod 311, and both ends of the telescopic rod 35 are detachably connected to the mounting bracket 313 and the extension rod 34. During the transportation of the guide assembly 3 and the extension rod 34, the guide assembly 3 and the extension rod 34 can be transported and then installed separately, which takes up less space and is convenient for transportation.

[0038] See Figures 3 to 7 Furthermore, in this embodiment, the lifting mechanism 4 includes an inserting plate 41 and a jack 42 provided on the inserting plate 41. The two sides of the inserting plate 41 are respectively inserted into the slots 33 on both sides of the guide channel 32. The jack 42 is used to lift the tool 6 into the tool box 51. The two sides of the inserting plate 41 are respectively provided with a limiter 411 for preventing the inserting plate 41 from falling out of the slot 33. Specifically, the limiter 411 is a limit block. The limit block has a simple structure and is easy to use. It does not hinder the installation of the inserting plate 41. Through reasonable arrangement, the limit block can abut against the guide rod 311 to prevent the inserting plate 41 from falling out of the guide assembly 3. At the same time, it can also limit the depth of the inserting plate 41 inserted into the guide channel 32, ensuring that the jack 42 can abut the middle part of the tool 6. When the tool 6 is lifted, the movement is more stable and safer.

[0039] See Figures 1 to 5 Furthermore, in this embodiment, the first lifting mechanism 1 includes a first mounting base 11, a first lifting hoist 12, and a first lifting rope 13. The first mounting base 11 is detachably mounted on the tool box 51, the first lifting hoist 12 is disposed on the first mounting base 11, and the first lifting rope 13 is disposed on the first lifting hoist 12 for connecting to the tool 6. Specifically, the first mounting base 11 is detachably connected to the tool box 51 via bolts.

[0040] See Figure 1 、 Figure 3 and Figure 5Furthermore, in this embodiment, the second lifting mechanism 2 includes a second mounting base 21, a second lifting hoist 22, and a second lifting rope 23. The second mounting base 21 is detachably mounted on the cutterhead 5, the second lifting hoist 22 is mounted on the second mounting base 21, and the second lifting rope 23 is mounted on the second lifting hoist 22 for connecting to the cutterhead 6. Specifically, the second mounting base 21 is detachably connected to the cutterhead 5 via bolts, thereby improving the utilization efficiency of the second lifting mechanism 2 and reducing the installation cost.

[0041] The operating principle of the inclined shaft TBM tool changing device of this embodiment is as follows:

[0042] After the cutterhead 5 stops rotating and retracts a distance to separate from the tunnel face, the tool box 51 where the damaged tool 6 is located is found, and the cutterhead 5 rotates a certain angle to move the tool box 51 to a suitable position; then the guide assembly 3 is installed on the tool box 51, the extension rod 34 is installed on the guide rod 311, the telescopic rod 35 is installed on the extension rod 34, and the second lifting mechanism 2 is installed at a suitable position on the cutterhead 5; then, the jacking mechanism 4 is installed on the guide assembly 3, and the jack 42 is raised to resist the bottom of the damaged tool 6; then the damaged tool 6 is lifted. The damaged tool 6 is removed from the tool box 51, and the jack 42 retracts to drive the damaged tool 6 to move into the guide channel 32 in the guide assembly 3; then the first lifting mechanism 1 is installed on the tool box 51, and the first lifting mechanism 1 is connected to the damaged tool 6; thereafter, the jack 42 continues to retract a distance to separate from the damaged tool 6, and after separation, the jacking mechanism 4 is removed; the first lifting mechanism 1 drives the damaged tool 6 to move downward along the guide channel 32 to the bottom end of the guide corridor; then the second lifting mechanism 2 is connected to the damaged tool 6, and together with the first lifting mechanism 1, the damaged tool 6 is lifted to the ground; after the damaged tool 6 is removed from the first lifting mechanism 1 and the second lifting mechanism 2, the first lifting mechanism 1 and the second lifting mechanism 2 are connected to the new tool 6; then the telescopic rod 35 retracts to drive the extension rod 34 to rotate outward; then the first lifting mechanism 1 and the second lifting mechanism 2 lift the new tool 6 to the appropriate position, and the telescopic rod 35 extends to drive the extension rod 34 to reset. During this process, the position of the new tool 6 relative to the extension rod 34 is adjusted; then the second lifting mechanism 2 is connected to the damaged tool 6 Mechanism 2 is separated from the new cutter 6, and the first hoisting mechanism 1 continues to lift the new cutter 6 until it is properly positioned in the guide channel 32. Next, the lifting mechanism 4 is installed on the guide assembly 3, and the jack 42 is raised so that it rests against the bottom of the new cutter 6. The first hoisting mechanism 1 is then removed, and the jack 42 lifts the new cutter 6 into the cutter box 51, completing the installation of the new cutter 6. Finally, the various components of the inclined shaft TBM tool changing device are removed from the cutterhead 5 and cutter box 51, and the next cutter 6 to be replaced is located. These steps are repeated until all damaged cutters 6 on the cutterhead 5 have been replaced.
