Description

Technical Field

[0001] This utility model relates to the field of TBM construction technology, specifically to a slag removal device for TBM construction. Background Technology

[0002] TBM tunnel construction refers to a mechanized construction method that uses a full-face tunnel boring machine (TBM) for tunnel excavation, support, and muck removal. Generally, a matching trolley is connected to the rear of the TBM main unit, and a TBM conveyor belt is installed on it. Currently, during construction, muck often falls directly onto the conveyor belt. Due to the height, after long-term use, the service life of the conveyor belt is shortened, making maintenance inconvenient.

[0003] To address the aforementioned technical issues, Chinese patent CN220011142U, a slag removal device for TBM construction, describes a method that uses a buffer box installed on the belt conveyor and two inclined buffer plates inside to buffer the falling slag. After passing through the two buffer plates, the impact force of the slag is significantly reduced, and the buffered slag falls directly into the middle of the belt conveyor through the slag outlet of the buffer box. This effectively prevents the slag from directly impacting the belt conveyor and causing belt misalignment, thus ensuring the belt's service life. While the aforementioned patent does overcome the technical problems through buffer plates, corresponding issues arise. Prolonged slag falling will inevitably cause wear on the buffer plates. Furthermore, the buffer plates in this patent are fixedly installed, so over time, they may become damaged and unable to continue buffering.

[0004] Therefore, in order to overcome the aforementioned technical problems and improve the service life of the guide plate through a more effective buffer structure, a slag removal device for TBM construction is proposed, thereby overcoming the aforementioned technical problems. Utility Model Content

[0007] Further, the stop structure includes a mounting block, a connecting shaft one, a sealed bearing one, a guide plate one, a mounting plate, a connecting block one, a sealed bearing two, a connecting shaft two, and a connecting block two. The mounting blocks are installed on the inner side of the outer shell and are symmetrically distributed along the vertical longitudinal section of the outer shell. A connecting shaft one connects the two sets of mounting blocks. A sealed bearing one is installed on the surface of the connecting shaft one. A guide plate one is connected to the outer ring of the sealed bearing one. A mounting plate is installed on the lower end face of the guide plate one, and connecting blocks one are symmetrically installed on its outer surface. A connecting shaft two connects the two sets of connecting blocks one. A connecting block two is installed on the surface of the connecting shaft two through the sealed bearing two. The lower end face of the connecting block two is connected to the upper end face of the guide post.

[0008] Furthermore, a protective shell is also installed on the inner side of the outer casing, which encloses the mounting block.

[0009] As a preferred technical solution, two sets of connecting plates are installed on the upper end face of the mounting block, wherein the upper end face of the connecting plate is provided with an arc surface and is connected to the lower end face of the protective shell.

[0010] Furthermore, a guide plate with an inclined surface is also installed on the inner side of the outer casing.

[0011] As a preferred technical solution, the outer shell structure includes an outer shell and a funnel; the outer shell is installed on the surface of the belt conveyor structure, and both the upper and lower ends of the outer shell are provided with openings, and the funnel is installed on the upper end of the outer shell.

[0014] This device, consisting of a mounting plate, connecting block one, sealed bearing two, connecting shaft two, guide column, buffer tube, telescopic spring one, and connecting block two, allows slag to enter the outer casing through the feed hopper and contact the guide plate one. Through the aforementioned structural arrangement, the telescopic springs one and two buffer the slag. Furthermore, the guide plate one is movable, thus effectively achieving buffering through the cooperation of the telescopic springs. This prevents the risk of wear and damage to the guide plate one over time, significantly extending its service life. It solves the problem of existing slag cleaning devices where the buffer plate is fixed and will eventually damage, hindering subsequent buffering operations. It also more effectively prevents conveyor belt damage caused by the weight of the slag. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-8 This utility model provides the following technical solution: a slag removal device for TBM construction, including a belt conveyor structure, on which a slag removal buffer device is installed. The slag removal buffer device includes an outer shell structure, which is installed on the belt conveyor structure. A buffer structure is installed inside the outer shell structure. The buffer structure is divided into two groups and installed on the inner side of the outer shell structure respectively. The buffer structure includes a baffle structure and a buffer assembly. The buffer assembly is connected to the baffle structure, and the buffer assembly includes a mounting plate 13, a connecting block 14, a sealed bearing 15, a connecting shaft 16, a guide post 17, a buffer tube 18, a telescopic spring 19, and a connecting block 23. The mounting plate 13 is installed inside the outer shell structure. On the side, and symmetrically mounted on the surface of the mounting plate 13, there are connecting blocks 14. A connecting shaft 16 is connected between the two sets of connecting blocks 14. A sealed bearing 15 is mounted on the surface of the connecting shaft 16. A connecting block 23 is mounted on the outer ring of the sealed bearing 15. A buffer tube 18 is connected to one end of the connecting block 23. A set of telescopic springs 21 is placed on the inner side of the buffer tube 18. A set of guide posts 17 is inserted into the inner side of the buffer tube 18. A top plate 20 is installed at the end that contacts the telescopic springs 21. The other end of the guide post 17 is connected to the baffle structure. A set of telescopic springs 19 is also sleeved between the upper end of the buffer tube 18 and the baffle structure.

[0026] In this implementation plan, the specific working principle is as follows: The core of this device is the use of telescopic springs 1-19 and 2-21. When the slag enters the outer shell 5 and contacts the guide plate 1, gravity is transmitted through the guide column 17. Firstly, the initial buffering is achieved through telescopic spring 1-19. As the guide column 17 moves into the buffer tube 18, a second buffering occurs through the contact between the top plate 20 and telescopic spring 2-21. Therefore, based on these two buffering processes, damage to the guide plate 1 from the slag is effectively reduced. Secondly, refer to... Figure 4 As can be seen, the buffer structure is equipped with two sets of buffers located as follows: Figure 4 At the location shown, a double-layer buffer is achieved, thereby effectively preventing damage to conveyor belt 4.

Figure 6 and Figure 7 As can be seen, the mounting blocks 7 are installed on the inner side of the outer shell 5 and are symmetrically distributed along the vertical longitudinal section of the outer shell 5. A connecting shaft 8 is connected between the two sets of mounting blocks 7 to provide an installation position for the sealing bearing 9. The sealing bearing 9 is installed on the surface of the connecting shaft 8 to facilitate the adjustment of the guide plate 1. The sealing bearing 9 also has the function of preventing dust from entering and causing the guide plate 1 to be difficult to adjust. The outer ring of the sealing bearing 9 is connected to the guide plate 1. In addition, a set of rubber pads can be installed on the upper end face of the guide plate 1, which can also improve the service life of the guide plate 1. Furthermore, the size of the rubber pads is consistent with the installation area on the upper end face of the guide plate 1. The mounting plate 13 is installed on the lower end face of the guide plate 1, and the connecting blocks 14 are symmetrically installed on the outer surface. A connecting shaft 26 is connected between the two sets of connecting blocks 14. A connecting block 23 is installed on the surface of the connecting shaft 26 through the sealing bearing 25. The lower end face of the connecting block 23 is connected to the upper end face of the guide post 17.

[0028] Based on the above, to prevent slag from falling into the gap between the connecting shaft 8 and the inner side of the outer casing 5, which could cause the guide plate 1 to jam, please refer to the figure for details. Figure 6 and Figure 7 As can be seen, a protective shell 12 is also installed on the inner side of the outer shell 5, and the protective shell 12 encloses the mounting block 7.

[0029] Based on the above, in order to increase the strength of the protective shell 12, please refer to the following: Figure 7 As can be seen, two sets of connecting plates 11 are installed on the upper end face of the mounting block 7, wherein the upper end face of the connecting plate 11 is provided with an arc surface and is connected to the lower end face of the protective shell 12.

[0030] To ensure that the slag accurately falls onto the conveyor belt 4 through the opening at the lower end of the outer casing 5, and to provide further cushioning, see [reference needed]. Figure 5 As can be seen, a guide plate 22 with an inclined surface is also installed on the inner side of the outer shell 5.

[0031] See Figure 3-5 As can be seen, the outer shell structure includes an outer shell 5 and a funnel 6; the outer shell 5 is installed on the surface of the belt conveyor structure, and both the upper and lower ends of the outer shell 5 are provided with openings, and the funnel 6 is installed on the upper end of the outer shell 5.

[0032] See Figure 1 and Figure 2 As can be seen, the belt conveyor structure includes a conveyor frame 1, a V-shaped roller 2, a servo motor 3, and a conveyor belt 4; the V-shaped roller 2 is equidistantly installed on the upper surface of the conveyor frame 1, the servo motor 3 is installed on one side of the conveyor frame 1, and the conveyor belt 4 is installed on its output end; a housing 5 is installed on the surface of the conveyor frame 1, and the opening at the lower end of the housing 5 corresponds to the upper surface of the conveyor belt 4.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
