Description

Technical Field

[0001] This utility model belongs to the field of tunnel boring machine technology and relates to a cleaning device for installing tunnel boring machine cutters. Background Technology

[0002] Auxiliary devices for tunnel boring machine (TBM) cutterhead installation typically refer to equipment used to accurately position and secure the cutters during installation or replacement. These devices generally consist of a support frame, a locator, and a fixing device, ensuring stable and reliable cutterhead installation and preventing uneven wear or reduced efficiency due to installation errors. Cleaning the cutterhead mounting slots of soil is crucial during TBM cutterhead installation, as the construction process generates a large amount of soil and gravel, which can easily accumulate in the mounting slots. Failure to clean these materials promptly may affect the accurate installation of the cutters.

[0003] Chinese invention application CN118933826A discloses an auxiliary device for a tunnel boring machine (TBM), including a front shield, a middle shield, and a propulsion machine. Several transmission rods are connected to one end of the front shield, and a cutterhead is connected to one end of each transmission rod. Several first mounting slots are formed on the surface of the cutterhead, with cutting tools connected to the inner walls of the first mounting slots. Several second mounting slots are formed on the side of the cutterhead. Before changing the drilling angle, the cutting tools use a rotating helical blade to create space, isolating the geological forces from causing turning resistance. By connecting the transmission rods and the cutterhead at one end of the front shield, connecting the cutting tools to the inner walls of the first mounting slots on the cutterhead surface, and installing development components in the second mounting slots on the side of the cutterhead, the pre-turning space for the cutting tools is expanded, reducing the turning resistance caused by the geological forces, extending the service life of the cutting tools, reducing the later maintenance costs of the TBM, and improving the working efficiency of the TBM. However, in actual use, after a period of operation, the cutting tool mounting slots on the cutterhead of the aforementioned patent document accumulate gravel and mud, making cleaning difficult and reducing the accuracy and efficiency of subsequent cutting tool installation.

[0004] Currently, the tool mounting slot is usually cleaned manually, which is inefficient, and there are no suitable automated cleaning tools available in the current technology. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figure 1 , Figure 6 As shown, the cleaning device for shield tunneling machine cutterhead installation provided by this utility model includes a base 1, a support plate 2, a support rod 3, a drive assembly 4, and a cleaning assembly 5. The support rod 3 is fixed to the center of the top surface of the base 1. Two support plates 2 are fixed to the rear edge of the upper center of the base 1 and the front edge of the upper center, respectively. The ends of the two support plates 2 that are close to each other are connected to the support rod 3. The drive assembly 4 is installed at the top of the support rod 3. Two cleaning assemblies 5 are installed on both sides of the drive assembly 4. The drive shaft of the drive assembly 4 is connected to the two cleaning assemblies, thereby simultaneously driving the cleaning assemblies 5 to rotate. In this example, the two cleaning assemblies 5 are connected to cleaning mechanisms with different functions. Figure 1 In the middle, a cleaning roller 6 is fixedly connected to the left end of the connecting plate 55 located at the rear, and a stirring roller 7 is fixedly connected to the right end of the connecting plate 55 located at the front.

[0029] By setting cleaning components 5 on both sides of the drive component 4 and cooperating with different cleaning mechanisms, the dirt remaining inside the tool mounting slot can be broken and cleaned, and it can also be supported inside the tool mounting slot.

[0030] For details, please refer to Figure 1 , Figure 2 ,and Figure 3The drive assembly 4 includes a housing 41, a heat sink 42, and a motor 43. The housing 41 is fixed to the upper end of the support rod 3, and the heat sink 42 is fixed to the middle of the upper end of the housing to dissipate heat from the motor 43. The output end of the motor 43 passes through the upper end of the housing 41 and extends into the interior of the housing 41. A bevel gear 44 is rotatably connected to the middle of the bottom wall of the housing 41. A connecting rod 45 is fixedly connected to the output end of the motor 43 via a coupling. The connecting rod 45 is fixedly connected to the bevel gear 44. A bevel gear 46 is rotatably connected to the middle of the rear side wall and the middle of the front side wall of the inner surface of the housing 41. Both bevel gears 46 mesh with bevel gear 44. The ends of the two bevel gears 46 that are far apart from each other are fixedly connected to transmission rods 47. The ends of the two transmission rods 47 that are far apart from each other pass through the left and right ends of the housing 41 and extend to the outside.

[0031] As can be seen from the above, when the motor 43 is started, the output end of the motor 43 will drive the connecting rod 45 fixedly connected to it to rotate. When the connecting rod 45 rotates, it can drive the bevel gear 44 fixedly connected to it to rotate on the bottom wall of the outer casing 41. Since the two bevel gears 46 are meshed with the bevel gear 44, when the bevel gear 44 rotates, it can simultaneously drive the two bevel gears 46 meshing with it to rotate. When the two bevel gears 46 rotate, they can drive the transmission rod 47 on the same side to rotate, thereby achieving the effect of driving the two cleaning components 5 to rotate. This realizes the use of the same power source to drive multiple structures for transmission, thereby improving the utilization rate of the power source.

[0032] The cleaning components 5 on both sides have the same structure; please refer to the documentation for details. Figure 4 and Figure 5 The following detailed explanation is provided using the cleaning component 5 on one side as an example. The cleaning component 5 includes a hollow column 51, a hollow plate 52, an auxiliary transmission component 53, an expansion component 54, and a connecting plate 55. The hollow column 51 is rotatably connected to the front side of the outer surface of the transmission rod 47, and its right end is fixedly connected to the left end of the outer shell 41. The hollow plate 52 is rotatably connected to the rear side of the outer surface of the transmission rod 47, and its right end is fixedly connected to the left end of the hollow column 51. The auxiliary transmission component 53 is fixedly installed on the left end of the transmission rod 47, and the expansion component 54 is slidably installed on its inner surface. The connecting plate 55 is fixedly connected to the auxiliary transmission component 53. Specifically, the auxiliary transmission component 53 includes a cover plate 531 fixedly connected to the left end of the transmission rod 47. The outer surface of the cover plate 531 has a plurality of guide grooves 532 arranged in a circular array, and the outer side of the left end of the cover plate 531 has a plurality of arc-shaped holes 533 arranged in a circular array. The left end of the cover plate 531 is fixedly connected to the connecting plate 55.

[0033] Furthermore, the expansion assembly 54 is provided with several guide rods 541, each guide rod 541 being slidably connected to the inner surface of several guide grooves 532 in a radial pattern. An arc-shaped plate 542 is fixedly connected to the outer end of each guide rod 541, and a guide block 543 is fixedly connected to the side of each guide rod 541 that is close to each other on the left side. Arc-shaped holes 533 correspond one-to-one with guide rods 541, and each guide block 543 is located inside the arc-shaped hole 533 and can slide within the arc-shaped hole 533.

[0034] As can be seen from the above, the hollow column 51 on the same side is rotatably connected to the outer surface of the transmission rod 47 on the same side, and the hollow column 51 is fixedly connected to the outer shell 41. At the same time, a hollow plate 52 is rotatably connected to the rear side of the outer surface of the transmission rod 47, and the hollow plate 52 on the same side is fixedly connected to the hollow column 51 on the same side. Therefore, when the transmission rod 47 on the same side rotates, the cover plate 531 fixedly connected to the transmission rod 47 rotates. When the cover plate 531 rotates, since several guide blocks 543 are located in the inner cavity of several arc-shaped holes 533, when the cover plate 531 rotates, several guide blocks 543 slide from their initial positions in the corresponding arc-shaped holes 533 to the other side. At the same time as several guide blocks 543 slide, they can drive the corresponding guide rod 541 to slide outward from the guide groove 532, and then make the arc-shaped plate 542 fit against the inner wall of the tool mounting groove. During the fitting process, the connecting plate 55 will follow the rotation of the cover plate 531 and drive the stirring roller 7 to rotate. During the cleaning process, the stirring roller 7 crushes the soil inside the tool mounting groove. When it is necessary to clean the debris inside the tool mounting groove after crushing, simply turn the end with the cleaning roller 6 towards the inside of the tool mounting hole, and then repeat the above operation steps to make the cleaning roller 6 continuously clean the inside of the tool mounting groove.

[0035] In this example, both the cleaning roller 6 and the stirring roller 7 are conventional designs in the prior art. The cleaning roller 6 in this design only needs to clean the inside of the tool mounting groove; its specific shape and installation method can be adjusted according to actual production needs. The stirring roller 7 only needs to break up the soil inside the tool mounting groove; its specific shape and installation method can also be adjusted according to actual production needs. These will not be described in detail here. The specific installation method of the motor 43, the circuit connection method, and the control method used in this invention are all conventional designs and will not be described in detail here.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
