Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel cleaning technology, specifically to a rapid cleaning device for TBM tunnels. Background Technology
[0002] After TBM (Tunnel Boring Machine) construction is completed, a large amount of mud, gravel, and other debris will remain at the bottom of the tunnel, requiring cleaning before the TBM can be withdrawn. In TBM tunnel projects, because the tunnel cross-section is circular, it is inconvenient for loaders to operate, and tunnel cleaning is mostly done manually, which is less safe and cannot meet the project schedule requirements. Utility Model Content
[0003] The problem this invention aims to solve is to provide a rapid slag removal device for TBM tunnels, which improves existing loaders so that they can perform slag removal operations inside circular TBM tunnels, reducing manual labor input, saving construction costs, and ensuring construction efficiency.
[0004] To solve the above-mentioned technical problems, this utility model provides a rapid slag removal device for TBM tunnels, including a loader, a leading edge shovel, a connecting plate, and two side baffles; the bottom plate of the loader's bucket is connected to the leading edge shovel through the connecting plate, thereby extending the bottom plate of the bucket; the leading edge shovel is an arc-shaped plate, and the outer diameter of the arc-shaped plate is the same as the inner diameter of the TBM tunnel, and the axis of the arc-shaped plate is arranged along the forward direction of the loader; the two side baffles are respectively fixed on both sides of the leading edge shovel and respectively fixedly connected to the side plates on the corresponding sides of the bucket.
[0005] In the aforementioned rapid slag removal equipment inside TBM tunnels, the leading edge shovel is an arc-shaped plate, and the outer diameter of the arc-shaped plate is the same as the inner diameter of the TBM tunnel. This allows the leading edge shovel, the connecting plate, and the two side baffles to form a groove-shaped inlet structure with an arc-shaped bottom surface at the bottom front end of the loader's bucket. This enables slag removal operations inside the circular TBM tunnel, reducing manual labor input, saving construction costs, and ensuring construction efficiency.
[0006] Furthermore, the width of the leading edge shovel is 0-100mm wider than the front edge width of the bucket bottom plate, reserving space for fixing the side baffles. Width refers to the dimension measured from the left-right direction of the loader, i.e., the horizontal direction.
[0007] Preferably, the side of the leading edge shovel plate away from the bucket is provided with a bevel to facilitate the insertion of slag.
[0008] Furthermore, the side baffle is a flat plate in the shape of a right trapezoid, with the bottom edge of the right trapezoidal plate fixedly connected to the side edge of the front edge shovel plate, and the right angle waist fixedly connected to the side plate on the corresponding side of the bucket.
[0009] Preferably, the length of the right-angled leg of the right-angled trapezoidal plate of the side baffle is 1 / 5 to 1 / 2 of the bucket height, ensuring connection strength and good side leakage prevention. The bucket height usually refers to the distance from the bottom of the bucket to its highest point.
[0010] Furthermore, the connecting plate is a bow-shaped flat plate, with the chord edge of the bow-shaped plate fixedly connected to the front edge of the bucket bottom plate and the bow-shaped edge fixedly connected to the edge of the front edge shovel plate near the bucket.
[0011] Preferably, the chord edge of the connecting plate has the same width as the front edge of the bucket bottom plate.
[0012] Preferably, the connecting plate extends obliquely from the outer side of the bottom plate of the bucket to the leading edge of the bottom plate. The inner side of the connecting plate forms an oblique transition slope, connecting the leading edge shovel and the bottom plate of the bucket. When shoveling excavated soil, the excavated soil first enters the lower leading edge shovel and then enters the bucket along the connecting plate.
[0013] Furthermore, the leading edge shovel plate, the connecting plate, and the two side baffles are all made of Q235 steel plate. Preferably, the steel plate thickness is 10mm, and each plate is fixedly connected to other components by welding.
[0014] In summary, the adoption of the aforementioned TBM-based rapid muck removal equipment in tunnels has improved the level of mechanization, increased muck removal efficiency, and further ensured the timely completion of the project. It has also reduced labor input, saved construction costs, and consequently ensured personnel safety, reducing the likelihood of accidents. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of the embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation on this utility model.
[0020] Example 1
[0021] Figure 1 and Figure 2This invention illustrates a rapid slag removal device for TBM tunnels. For example... Figure 1 and Figure 2 As shown, the rapid slag removal equipment inside the TBM tunnel includes a loader, a leading edge shovel 2, a connecting plate 3, and two side baffles 4. The bottom plate of the loader's bucket 1 is connected to the leading edge shovel 2 through the connecting plate 3, thereby extending the bottom plate of the bucket 1. The leading edge shovel 2 is an arc-shaped plate, and the outer diameter of the arc-shaped plate is the same as the inner diameter of the TBM tunnel. The axis of the arc-shaped plate is arranged along the forward direction of the loader. The two side baffles 4 are fixed on both sides of the leading edge shovel 2 and are fixedly connected to the side plates of the corresponding sides of the bucket 1.
[0022] Optionally, the width of the front edge shovel 2 is 0-100mm wider than the front edge width of the bottom plate of the bucket 1, to reserve space for fixing the side baffle 4. The width refers to the dimension measured from the left and right direction of the loader, that is, the horizontal direction. In addition, the central angle of the front edge shovel 2 is less than 108°, and the side of the front edge shovel 2 away from the bucket 1 is provided with a bevel to facilitate the insertion of slag.
[0023] Optionally, the side baffle 4 is a flat plate in the shape of a right trapezoid, with the bottom edge of the right trapezoidal plate being fixedly connected to the side edge of the front edge shovel 2, and the right angle waist being fixedly connected to the side plate on the corresponding side of the bucket 1.
[0024] Optionally, the length of the right-angled waist of the right-angled trapezoidal plate of the side baffle 4 is 1 / 5 to 1 / 2 of the height of the bucket 1 to ensure connection strength and good side leakage prevention. The bucket height usually refers to the distance from the bottom of the bucket to the highest point of the top.
[0025] Optionally, the connecting plate 3 is a flat plate in the shape of an arc, with the chord edge of the arc-shaped plate fixedly connected to the front edge of the bottom plate of the bucket 1, and the arc-shaped edge fixedly connected to the edge of the front edge shovel plate 2 near the bucket 1.
[0026] Optionally, the chord edge of the connecting plate 3 is the same width as the front edge of the bottom plate of the bucket 1, ensuring that the extension structure of the bottom plate of the bucket 1 is properly connected to the bucket.
[0027] Optionally, the surface of the connecting plate 3 extends obliquely from the outside of the bottom plate of the bucket 1 to the leading edge of the bottom plate. The inner surface of the connecting plate 3 forms an oblique transition slope, connecting the front edge shovel 2 and the bottom plate of the bucket 1. When shoveling excavated soil, the excavated soil first enters the lower front edge shovel 2, and then enters the bucket 1 along the connecting plate 3.
[0028] Optionally, the leading edge shovel plate 2, the connecting plate 3, and the two side baffles 4 are all made of Q235 steel plate, which is simple to manufacture and low in cost. Preferably, the steel plate thickness is 10mm, and each plate is fixedly connected to other components by welding.
[0029] In use, it is first assembled from four 10mm thick Q235 steel plates welded together, and each plate is processed into a front edge shovel 2, a connecting plate 3, and two side baffles 4. Then, it is welded to the loader bucket 1. The connecting plate 3 connects the front edge shovel 2 to the bottom plate of the bucket 1, filling the gap between them; the front edge shovel 2 fits against the bottom arc of the tunnel to clear the slag; the two side baffles 4 connect the front edge shovel 2 to the bucket 1, reinforcing the overall structure and increasing the bucket capacity, making the slag removal operation more efficient.
