[0019] 1. A dual-mode TBM cutter head tool placement device described in the present invention connects the connecting shafts at the upper and lower ends of the micro-cutters with the corresponding two strip members through the cooperation of the connecting grooves and the strip members, and multiple micro-cutters are installed on the side of the placement disk in the same way. Under electric drive, the placement disk drives multiple micro-cutters to move toward the position of the micro-cutter head until the strip members contact the corresponding mounting strips. Under electric drive, multiple pushing components drive the micro-cutters to move toward the mounting groove direction until the connecting shafts break away from the strip members and slide onto the mounting strips. After the micro-cutters move to the extreme position, multiple micro-cutters will be initially placed on the micro-cutter head.

[0020] 2. The dual-mode TBM cutter head tool placement device described in the present invention enables the locking piece to be threadedly connected inside the cylindrical groove through the movement and rotation of the locking piece, and the end of the tapered column moves inside the cylindrical groove to push out multiple limiting members, so that the limiting members are inserted into the corresponding limiting grooves, thereby further fixing the micro-tools and detecting whether the installation position of the micro-tools deviates. Multiple micro-tools are fixed and position-detected for a second time inside the micro-cutter head through a one-time placement process, which can ensure that there will be no position errors in the subsequent installation of the micro-tools and complete simple steps at one time to avoid wasting manpower.

[0021] 3. A dual-mode TBM cutter head tool placement device described in the present invention has an inclination angle of the inclined surface that is consistent with the inclination angle of the conical column. When the conical column moves, the column body can be pushed out, and the pushed out column will be embedded in the corresponding limit groove. The setting of the conical limit column can avoid the position of the column body and the limit groove from being offset. After multiple columns are pushed out, the locking member can be rotated through the rotation and telescopic structure inside the strip component, that is, the threaded column is threadedly connected to the end of the cylindrical groove, so as to further fix the micro tool and the mounting strip. After the threaded connection is completed, the through groove is in a horizontal state and is at the same horizontal height as the threaded through groove, which is convenient for the subsequent connection of bolts.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1-6 As shown, a dual-mode TBM cutter head tool placement device according to an embodiment of the present invention comprises a track bar 4, a placement disc 3 is movably mounted above the track bar 4, a micro cutter head 1 is placed at the end of the track bar 4, a plurality of micro cutters 2 are movably mounted inside the micro cutter head 1, a connecting shaft 21 is fixedly mounted above and below the micro cutters 2, and a connecting groove 22 is provided inside the connecting shaft 21;

[0036] A plurality of pushing components 5 are movably installed inside the laying disk 3, and a strip component 6 is installed on the upper and lower parts of one pushing component 5, and a plurality of strip components 6 are installed on the side of the laying disk 3. A plurality of mounting grooves 11 are opened through the inside of the micro-knife disk 1, and the plurality of mounting grooves 11 are at the same horizontal position as the plurality of corresponding pushing components 5. Welding blocks 13 are fixedly installed on the inner top and inner bottom of the mounting groove 11, and a motor shaft 14 is movably installed on the inner top and inner bottom of the mounting groove 11, and a mounting strip 15 is fixedly installed below the motor shaft 14.

[0037] Specifically, when the micro-cutter disc 1 needs to be installed with the micro-cutter 2, the micro-cutter disc 1 can be placed on the track bar 4 first, so that the micro-cutter disc 1 and the layout disc 3 are in the same axial position, and the micro-cutter 2 is taken and installed on the side of the micro-cutter 2. The specific installation method is to cooperate with the connecting groove 22 and the strip component 6 so that the connecting shaft 21 at the upper and lower ends of the micro-cutter 2 is connected to the corresponding two strip components 6. In the same way, multiple micro-cutters 2 are installed on the side of the layout disc 3. Under the power drive, the layout disc 3 drives the multiple micro-cutters 2 to move to the position of the micro-cutter disc 1 until the strip component 6 is connected. Component 6 is in contact with the corresponding mounting strip 15, and multiple pushing components 5 driven by electricity drive the micro-tool 2 to move toward the mounting groove 11 until the connecting shaft 21 separates from the strip-shaped component 6 and slides onto the mounting strip 15. When the micro-tool 2 moves to the extreme position, multiple micro-tools 2 will be initially arranged on the micro-tool disc 1. After subsequent tightening, the motor shaft 14 can be driven by electricity to drive the mounting strip 15 and the micro-tool 2 to rotate, thereby playing a role in excavation. Through the arranged structure, multiple micro-tools 2 can complete the initial installation steps at one time to avoid waste of manpower.

[0038] like Figure 1-2 As shown in 4, a movable track block 41 is slidably installed above the track bar 4, and the movable track block 41 is fixedly connected to the layout disk 3. A fixed arc block 42 is fixedly installed at the end of the track bar 4. An arc groove 421 is provided inside the fixed arc block 42, and a plurality of fixed bars 422 are fixedly installed inside the arc groove 421. A plurality of matching bar grooves 12 are provided on the outer side of the micro cutter disc 1, and the plurality of matching bar grooves 12 match the corresponding fixed bars 422. A matching groove 16 is provided on the side of the micro cutter disc 1 close to the layout disk 3, and the matching groove 16 matches the installation groove 11.

[0039] Specifically, by matching the strip groove 12 with the fixing strip 422, the micro-cutting disc 1 can be placed inside the arc groove 421 and fixed. The placed micro-cutting disc 1 is now on the same axis as the layout disc 3. Under electric drive, the movable track block 41 can drive the layout disc 3 to move until the layout disc 3 slides into the matching groove 16, that is, at this time, part of the micro-cutting tool 2 installed on the layout disc 3 is inside the installation groove 11.

[0040] like Figure 6 As shown, the pushing assembly 5 includes a pushing block 51 slidably installed inside the routing disk 3, a tool groove 52 is opened inside the pushing block 51, a telescopic column 53 is fixedly installed on the side of the pushing block 51, and the end of the telescopic column 53 is fixedly connected to the inside of the groove of the routing disk 3.

[0041] Specifically, the tool groove 52 perfectly matches the side of the micro-tool 2, so after the strip member 6 slides into the connecting groove 22, the micro-tool 2 can be in close contact with the tool groove 52 to stabilize the placement of the micro-tool 2. When the micro-tool 2 needs to be installed inside the micro-tool disc 1, the electric drive of the telescopic column 53 drives the push block 51 and the micro-tool 2 to move into the micro-tool disc 1.

[0042] like Figure 7 As shown, a locking member 7 is movably installed inside the strip member 6, and the locking member 7 includes a movable column 71 located inside the strip member 6 and a threaded column 72 fixedly installed at one end of the movable column 71, and a conical column 73 is installed at the other end of the movable column 71. A through groove 74 is opened inside the movable column 71, and the through groove 74 matches the threaded through groove 151. One end of the threaded column 72 is detachably connected to the rotating telescopic member inside the strip member 6.

[0043] like Figure 7-8 As shown, a through thread groove 24 and a plurality of limit grooves 23 are provided inside the connecting shaft 21, and the through thread groove 24 and the limit grooves 23 are connected with the connecting groove 22. A threaded through groove 151 and a plurality of component grooves 152 are provided inside the mounting strip 15, and a limiting component 153 is slidably installed inside the plurality of component grooves 152, and the plurality of component grooves 152 match the plurality of limit grooves 23, and the threaded through groove 151 matches the through thread groove 24. A cylindrical groove 154 is also provided inside the mounting strip 15.

[0044] Specifically, when the strip member 6 contacts the corresponding mounting strip 15, the micro-tool 2 can move toward the mounting strip 15 together with the tool slot 52 through the extension and retraction of the telescopic column 53 until the micro-tool 2 is pushed to the limit position inside the mounting slot 11. At this time, the mounting strip 15 slides inside the connecting slot 22, and the locking member 7 can be installed inside the strip member 6. The locking member 7 is installed inside the strip member 6 by a detachable installation method and is connected to the rotating and retractable structure inside the strip member 6. Specifically, the end of the threaded column 72 has a groove that can be engaged with the rotating and retractable structure inside the strip member 6, and then the rotating and retractable structure drives the locking member 7 to move and rotate. When the micro-tool 2 is inside the mounting slot 11, the locking member 7 is threadedly connected inside the cylindrical slot 154 through the movement and rotation of the locking member 7, and the end of the conical column 73 moves inside the cylindrical slot 154 to push out multiple limiting members 153. The limiting member 153 is inserted into the corresponding limiting groove 23, which further fixes the micro tool 2 and can detect whether the installation position of the micro tool 2 is deviated. Multiple micro tools 2 are fixed and position detected twice inside the micro tool disk 1 through a layout process, which can ensure that the subsequent installation of the micro tool 2 will not have position errors, and the simple steps are completed at one time to avoid wasting manpower. After the simple steps are completed, it is necessary to take the bolt and make it threadedly connected to the through-thread groove 24 and the threaded through groove 151, and at this time pass through the through groove 74. The end of the bolt can be hidden in one end of the through-thread groove 24, and the other end of the bolt is locked by a nut, which can be hidden at the other end of the through-thread groove 24. Subsequent precision operations are completed by manpower. Through this layout and installation method of the micro tool 2, the installation efficiency of the micro tool 2 is effectively improved.

[0045] Embodiment 2

[0046] like Figure 8-9 As shown, compared with Example 1, another embodiment of the present invention is: the component groove 152 includes a large diameter groove 1521 opened on the inner wall of the cylindrical groove 154 and a small diameter groove 1522 opened in the mounting strip 15, the large diameter groove 1521 and the small diameter groove 1522 are connected, the diameter of the cylindrical groove 154 matches the diameter of the movable column 71, the limiting component 153 includes a column 1531 slidably installed in the component groove 152, a movable ring 1534 is fixedly installed on the outer side of the column 1531, the movable ring 1534 slides in the large diameter groove 1521, and a plurality of connecting springs 1535 are fixedly installed on the side of the movable ring 1534, and one end of the connecting spring 1535 is fixedly connected to the inside of the mounting strip 15.

[0047] like Fig. 9As shown, an end of the column 1531 facing the inside of the cylindrical groove 154 is provided with an inclined surface 1533 , the inclined surface 1533 matches the conical column 73 , and a conical limiting column 1532 is fixedly installed at the other end of the column 1531 .

[0048] Specifically, through the rotation and telescopic structure inside the strip member 6, the locking member 7 can first move into the cylindrical groove 154 until the moving column 71 and the tapered column 73 can slide into the cylindrical groove 154. At this time, the through groove 74 is arranged in an upper and lower position. The movement of the moving column 71 and the tapered column 73 can push the column 1531 to move toward the outside of the mounting strip 15. At this time, the moving ring 1534 moves inside the large diameter groove 1521, and the connecting spring 1535 is compressed. The inclination angle of the inclined surface 1533 is consistent with the inclination angle of the tapered column 73, ensuring that the tapered column 73 can push the column 1531 out when it moves, and the pushed-out column 1531 will be embedded in the corresponding limiting groove 23. The setting of 1532 can avoid the position offset of the column 1531 and the limit groove 23. After multiple columns 1531 are pushed out, the locking member 7 can be rotated through the rotation and telescopic structure inside the strip component 6, that is, the threaded column 72 is threadedly connected with the end of the cylindrical groove 154, so as to further fix the micro tool 2 and the mounting strip 15. After the threaded connection is completed, the through groove 74 is in a horizontal state and is at the same horizontal height as the threaded through groove 151, which is convenient for the subsequent bolt connection. An installation groove 11 is provided on the outer side of the micro tool disc 1. When the micro tool 2 needs to be installed, it can be preliminarily installed in the above manner, that is, the pushing component 5, the strip component 6, the locking member 7 and the mounting strip 15 are also set.

[0049] Working principle: when the micro-cutter disc 1 needs to be installed with the micro-cutter 2, the micro-cutter disc 1 can be placed on the track bar 4 first, so that the micro-cutter disc 1 and the layout disc 3 are in the same axial position, and the micro-cutter 2 is taken and installed on the side of the micro-cutter 2. The specific installation method is to cooperate with the connecting groove 22 and the strip member 6 so that the connecting shaft 21 at the upper and lower ends of the micro-cutter 2 is connected to the corresponding two strip members 6, and multiple micro-cutting tools 2 are installed on the side of the layout disc 3 in the same way. Under electric drive, the layout disc 3 drives the multiple micro-cutting tools 2 to move toward the position of the micro-cutter disc 1 until the strip member 6 contacts the corresponding installation strip 15. Under electric drive, the multiple pushing components 5 drive the micro-cutter 2 to move in the direction of the installation groove 11 until it contacts the corresponding installation strip 15. Until the connecting shaft 21 is separated from the strip component 6 and slides onto the mounting strip 15, when the micro-tool 2 moves to the extreme position, multiple micro-tools 2 will be initially arranged on the micro-tool disc 1. After subsequent tightening, the electric drive motor shaft 14 can be used to drive the mounting strip 15 and the micro-tool 2 to rotate, thereby playing a role in excavation. Through the arranged structure, multiple micro-tools 2 can complete the initial installation steps at one time, avoiding waste of manpower. When the strip component 6 contacts the corresponding mounting strip 15, the micro-tool 2 can be moved toward the mounting strip 15 together with the tool slot 52 through the extension and contraction of the telescopic column 53, until the micro-tool 2 is pushed to the extreme position inside the mounting slot 11, and the mounting strip 15 slides in the connecting slot 22. The locking member 7 can be installed inside the strip member 6. The locking member 7 is installed inside the strip member 6 by a detachable installation method and is connected to the rotating and retractable structure inside the strip member 6. Specifically, the end of the threaded column 72 has a groove that can be engaged with the rotating and retractable structure inside the strip member 6, and then the rotating and retractable structure drives the locking member 7 to move and rotate. When the micro-tool 2 is in the installation groove 11, the locking member 7 is threadedly connected inside the cylindrical groove 154 through the movement and rotation of the locking member 7. The end of the conical column 73 moves inside the cylindrical groove 154 to push out multiple limiting members 153, so that the limiting members 153 are inserted into the corresponding limiting grooves 23, thereby further fixing the micro-tool 2 and being able to be fixed. In order to detect whether the installation position of the micro-tool 2 is deviated, multiple micro-tools 2 are fixed and positionally detected twice inside the micro-tool disc 1 through a layout process, which can ensure that the subsequent installation of the micro-tool 2 will not have position errors, and the simple steps can be completed at one time to avoid wasting manpower. After the simple steps are completed, it is necessary to take the bolt and make it threadedly connected inside the through-thread groove 24 and the threaded through groove 151, and at this time, it passes through the through groove 74. The end of the bolt can be hidden at one end inside the through-thread groove 24, and the other end of the bolt is locked by a nut, which can be hidden at the other end of the through-thread groove 24. Subsequent precision operations are completed by manpower. Through this layout and installation method for the micro-tool 2,The installation efficiency of the micro tool 2 is effectively improved.
