[0037] Such as Figures 1 to 7As shown, the present application provides a cutter head assembly for a raise borer, which includes a rotary cylinder 100 and multiple support plates 200. The rotary cylinder 100 is provided with a through hole along the axial direction. A plurality of hob grooves 110 and a plurality of first clamping grooves 120 are formed on the outer periphery of the rotary cylinder 100. The plurality of first clamping grooves 120 are respectively communicated with the plurality of hob grooves 110 and are arranged in one-to-one correspondence with the plurality of hob grooves 110. The multiple support plates 200 are detachably mounted on the outer periphery of the rotary cylinder 100, are arranged in one-to-one correspondence with the plurality of hob grooves 110, and are located at one end of the hob groove 110 away from the first clamping groove 120. The multiple support plates 200 are all provided with second clamping grooves 210.

[0038] It should be noted here that in this embodiment, the number of hob grooves 110 is set to two as an example for illustration. Of course, in other embodiments, according to actual application requirements, the number of hob grooves 110 can also be set to three, four, five... other numbers, which are not uniquely limited here. Since the plurality of first clamping grooves 120 are arranged in one-to-one correspondence with the plurality of hob grooves 110, the number of first clamping grooves 120 always remains the same as the number of hob grooves 110. Since the multiple support plates 200 are arranged in one-to-one correspondence with the plurality of hob grooves 110, the number of support plates 200 always remains the same as the number of hob grooves 110.

[0039] It should also be noted here that the axial directions above and below refer to the two-way directions of the central axis defined by the structure of the cylinder body 130 itself, specifically as Figure 1 shown by the X-axis in

[0040] In this embodiment, after the two support plates 200 are installed on the outer periphery of the rotary cylinder 100 through external bolts, the two hob structures 500 (the number of hob structures 500 always remains the same as the number of hob grooves 110) can be aligned with the two hob grooves 110. When installing the hob structure 500, the small-diameter end of the hob structure 500 is clamped into the first clamping groove 120, and the large-diameter end of the hob structure 500 is clamped into the second clamping groove 210. After the hob structure 500 is clamped into the first clamping groove 120 and the second clamping groove 210, the small-diameter end of the hob structure 500 is fixed to the rotary cylinder 100 through external bolts, and the large-diameter end of the hob structure is fixed to the support plate 200 through external bolts.

[0041] For the cutter head assembly for a raise borer provided by the present application, when disassembling and installing the hob structure 500, compared with the related art, through the first clamping groove 120 and the second clamping groove 210, the hob structure 500 can be directly replaced without disassembling the support plate 200, which is convenient for maintenance, helps to improve the maintenance efficiency, and thus helps to improve the operation efficiency.

[0042] In an embodiment of the present application, please refer to Figures 1 to 7, the rotary drum 100 includes a drum body 130, a first boss 140, a second boss 150, and a third boss 160. The first boss 140, the second boss 150, and the third boss 160 are all connected to the groove wall of the hob groove 110. The second boss 150 is connected to one end of the first boss 140, and the third boss 160 is connected to the end of the second boss 150 away from the first boss 140. The first boss 140, the second boss 150, and the third boss 160 enclose to form a first clamping groove 120. The first boss 140 is provided with a first mounting hole 170.

[0043] Specifically, in the related art, after the hob structure 500 is clamped into the first clamping groove 120, an external bolt is first passed through the small-diameter end of the hob structure 500, and then the external bolt is screwed into the first mounting hole 170 to fix the small-diameter end of the hob structure 500. However, in the actual application process, under the action of the circumferential force on the hob structure 500 under the action of the rotary assembly, the tensile stress between the drum body 130 and the hob structure 500 is concentrated on the external bolt. Therefore, the external bolt is easily disengaged from the first mounting hole 170, which easily causes the hob structure 500 to fall off from the drum body 130.

[0044] With such a setting, during the tunneling process, through the third boss 160, the small-diameter end of the hob structure 500 can be limited, preventing the hob structure 500 from gradually moving away from the first boss 140 on the surface of the second boss 150. Compared with the related art, it can avoid the tensile stress being concentrated on the external bolt, which helps to improve the tensile performance of the drum body 130 on the hob structure 500, and thus helps to improve the structural stability between the drum body 130 and the hob structure 500. And during the tunneling process, through the first mounting hole 170, it can be used to install the external bolt, and can also limit the small-diameter end of the hob structure 500, preventing the hob structure 500 from gradually moving away from the second boss 150 on the surface of the first boss 140, which helps to further improve the structural stability between the drum body 130 and the hob structure 500. To sum up, while ensuring the installation convenience of the hob structure 500, through the third boss 160, the hob structure 500 is not easily detached from the drum body 130, greatly reducing the number of repairs and helping to improve the operation efficiency.

[0045] In an embodiment of the present application, please refer to Figures 1 to 7, the support plate 200 includes a mounting plate 220, a first plate body 230, a second plate body 240, and a third plate body 250. The mounting plate 220 is detachably mounted at one end of the hob groove 110 away from the first card slot 120. Both the first plate body 230 and the second plate body 240 are connected to the mounting plate 220. The second plate body 240 is connected to one end of the first plate body 230. The third plate body 250 is connected to the end of the second plate body 240 away from the first plate body 230. The first plate body 230, the second plate body 240, and the third plate body 250 enclose to form a second card slot 210. The first plate body 230 is provided with a second mounting hole 260.

[0046] Specifically, in the related art, after the hob structure 500 is clamped into the second card slot 210, first, an external bolt is passed through the large-diameter end of the hob structure 500, and then the external bolt is screwed into the second mounting hole 260 to fix the large-diameter end of the hob structure 500. However, in the actual application process, under the action of the rotating assembly, under the action of the circumferential force, the tensile stress between the cylinder body 130 and the hob structure 500 is concentrated on the external bolt. Therefore, the external bolt is easily disengaged from the second mounting hole 260, and thus the hob structure 500 is easily detached from the support plate 200.

[0047] With such a setting, during tunneling, through the third plate body 250, the large-diameter end of the hob structure 500 can be limited, preventing the hob structure 500 from gradually moving away from the first plate body 230 on the surface of the second plate body 240. Compared with the related art, it can avoid the tensile stress concentrating on the external bolt, which helps to improve the tensile performance of the support plate 200 for the hob structure 500, and thus helps to improve the structural stability between the support plate 200 and the hob structure 500. And, during tunneling, through the second mounting hole 260, it can be used to install the external bolt, and can also limit the large-diameter end of the hob structure 500, preventing the hob structure 500 from gradually moving away from the second plate body 240 on the surface of the first plate body 230, which helps to further improve the structural stability between the support plate 200 and the hob structure 500. To sum up, while ensuring the installation convenience of the hob structure 500, through the third plate body 250, the hob structure 500 is not easily detached from the support plate 200, greatly reducing the number of repairs and helping to improve the operation efficiency.

[0048] In an embodiment of the present application, refer to Figures 1 to 7 , the cutter head assembly for raise boring machine further includes a plurality of balancing members 300, and the plurality of balancing members 300 are all detachably mounted on the outer periphery of the rotary cylinder 100.

[0049] It should be noted here that in this embodiment, the number of the balance members 300 is taken as two as an example for illustration. Of course, in other embodiments, the number of the balance members 300 can also be set to three, four, five... other numbers, which is not uniquely limited herein.

[0050] With such a setting, during the tunneling process, through the balance members 300, it is helpful to improve the rotation accuracy of the rotary drum 100 and the rotary sleeve 400, and avoid large deviations between the rotation axes of the rotary drum 100 and the rotary sleeve 400 and the rotation axis of the rotary assembly, which may cause damage to the raise boring machine. Similarly, it can reduce the number of repairs and help improve the operation efficiency. Moreover, during the tunneling process, through the balance members 300, it is helpful to improve the operation quality of the raise boring machine.

[0051] In an embodiment of the present application, please refer to Figures 1 to 7 , the balance member 300 includes a mounting base 310, a balance weight 320 and a plurality of wear-resistant teeth 330.

[0052] With such a setting, by using the mounting base 310, it is convenient to install the balance weight 320. During the tunneling process, through the balance weight 320, it is prevented that the mounting base 310 directly contacts the tunneling surface, which helps to extend the service life of the mounting base 310. During the tunneling process, through the plurality of wear-resistant teeth 330, it is helpful to improve the surface roughness of the balance weight 320. Therefore, under the action of the rotary assembly, the tunneling surface can be further polished, which helps to improve the operation quality. Moreover, the plurality of wear-resistant teeth 330 can also prevent the balance weight 320 from directly contacting the tunneling surface, which helps to extend the service life of the balance weight 320. In addition, the mounting base 310 is detachably mounted on the rotary drum 100, and the balance weight 320 is detachably mounted on the mounting base 310. The disassembly and installation are convenient, which is convenient for maintenance and helps to improve the convenience of use.

[0053] Optionally, the side of the balance weight 320 facing away from the mounting base 310 is set as an arc surface.

[0054] With such a setting, through the arc surface, the balance weight 320 can better fit the tunneling surface, which is convenient for the rotary assembly to drive the balance weight 320 to rotate.

[0055] Optionally, the wear-resistant teeth 330 are set as alloy teeth.

[0056] With such a setting, it is helpful to improve the wear resistance of the wear-resistant teeth 330.

[0057] In an embodiment of the present application, please refer to together Figures 1 to 7, the balance weight 320 includes a seat body 311, a wedge block 312 and two stop blocks 313. The wedge block 312 is connected to one side of the seat body 311 facing away from the rotary cylinder 100. The two stop blocks 313 are both connected to the seat body 311 and are respectively arranged at both ends of the wedge block 312. The balance weight 320 includes a block body 321 and a dovetail groove 322. The dovetail groove 322 is formed in the block body 321, and the wedge block 312 is clamped in the dovetail groove 322.

[0058] With such a setting, during the tunneling process, through the wedge block 312 and the dovetail groove 322, the seat body 311 and the block body 321 are clamped and connected, avoiding the relative movement of the block body 321 relative to the seat body 311 under the influence of the circumferential force, which helps to improve the structural stability between the seat body 311 and the block body 321. Moreover, during the tunneling process, through the two stop blocks 313, the block body 321 can be axially limited, avoiding the relative movement of the block body 321 relative to the seat body 311 under the influence of the axial force, which helps to further improve the structural stability between the seat body 311 and the block body 321. In summary, during the tunneling process, through the wedge block 312, the two stop blocks 313 and the dovetail groove 322, the balance weight 320 is not easily detached from the mounting seat 310, greatly reducing the number of repairs and helping to improve the operation efficiency.

Of course, in other embodiments, according to actual application requirements, the number of the limiting grooves 180 can also be set to three, four, five... other numbers, which is not uniquely limited here. The number of the limiting grooves 180 and the number of the balancing members 300 are always kept consistent.

[0061] With such a setting, during the tunneling process, through the plurality of limiting grooves 180, the cylinder body 130 and the seat body 311 are clamped and connected, avoiding the relative movement of the seat body 311 relative to the cylinder body 130 under the influence of the circumferential force, which helps to improve the structural stability between the seat body 311 and the cylinder body 130, making the seat body 311 not easily detached from the cylinder body 130, greatly reducing the number of repairs and helping to improve the operation efficiency.

[0062] In an embodiment of the present application, please refer to Figures 1 to 7 , the cutter head assembly for raise boring machine further includes a rotary sleeve 400.
