[0030] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0031] Reference Figure 1 and Figure 3 This disclosure provides an exemplary embodiment of a coal bunker bottom reinforcement device, which includes:

[0032] The frame 1 has multiple layers that are stacked and fixed in the vertical direction. The bottom frame 1 is fixed to the locking beam 6. The frame 1 includes an outer support frame 11 and an inner support frame 12. The outer support frame 11 is flush with the inner support frame 12. The outer support frame 11 frames the inner support frame 12. A first connector 5 for detachably connecting the inner support frame 12 is fixed on the outer support frame 11.

[0033] The filling layer 4 covers the outside of the frame 1 and covers the lock beam 6 and the outer wall of the frame 1;

[0034] The reinforcement 3 is fixed to the frame 1 and extends outside the frame 1. The reinforcement 3 is inserted and fixed inside the filling layer 4 outside the frame 1.

[0035] For example, refer to Figure 4 and Figure 6 The inner support frame 12 includes a first inner I-beam 121 and a second inner I-beam 122. The end of the second inner I-beam 122 is integrally formed with a connecting part 123 for extending into the interior of the first inner I-beam 121. The end of the second inner I-beam 122 with the connecting part 123 extends into the interior of the first inner I-beam 121. The end of the wing plate of the second inner I-beam 122 abuts against the side wall of the wing plate of the first inner I-beam 121. The top surface of the connecting part 123 abuts against the inner top surface of the first inner I-beam 121, and the bottom surface of the connecting part 123 abuts against the inner bottom surface of the first inner I-beam 121, forming a vertically engaging posture with the first inner I-beam 121.

[0036] ReferenceFigure 2 and Figure 5 The end of the second inner I-beam 122 is fixed with a third connector 2 for detachably connecting the first inner I-beam 121. The third connector 2 is attached to and fixed to the connecting part 123. The top surface of the third connector 2 is flush with the top surface of the connecting part 123, and the bottom surface of the third connector 2 is flush with the bottom surface of the connecting part 123, so that the third connector 2 covers the outer side wall of the connecting part 123. The third connector 2 has a horizontal L-shaped structure. The bending position of the third connector 2 is flush with the end of the connecting part 123 away from the second inner I-beam 122. The third connector 2 extends towards the end of the second inner I-beam 122 along the length direction of the second inner I-beam 122. The third connector 2 extends out of the flange of the first inner I-beam 121 and extends along the length direction of the second inner I-beam 122. The third connector 2 covers part of the outer side wall of the waist plate of the second inner I-beam 122.

[0037] A third connector 2 is welded to each of the two opposite sidewalls of the connecting part 123. The two third connectors 2 located on the same connecting part 123 are symmetrically distributed. After the third connector 2 is bent away from the solid structure of the second inner I-beam 122, it abuts against the sidewall of the waist plate of the first inner I-beam 121. The third connector 2 has a fixing bolt 7 on the solid structure away from the second inner I-beam 122 after being bent. After the fixing bolt 7 passes through the third connector 2 and the waist plate of the first inner I-beam 121, the third connector 2 is bolted to the waist plate of the first inner I-beam 121.

[0038] The outer support frame 11 includes a first outer I-beam 111 and a second outer I-beam 112. The end of the second outer I-beam 112 is also integrally formed with a connecting portion 123 for extending into the first outer I-beam 111. After extending into the first outer I-beam 111, the connecting portion 123 is vertically engaged with the first outer I-beam 111. Similarly, a third connecting member 2 is fixed at the same position on the connecting portion 123 of the second outer I-beam 112. The second outer I-beam 112 is fixed to the first outer I-beam 111 through the third connecting member 2. Therefore, the structure of the outer support frame 11 is consistent with that of the inner support frame 12, and will not be described further. The top surface of the outer support frame 11 is flush with the top surface of the inner support frame 12, and the bottom wall of the outer support frame 11 is flush with the bottom wall of the inner support frame 12.

[0039] The first inner I-beam 121 abuts against the first outer I-beam 111, and the flange sidewall of the first inner I-beam 121 abuts against the flange sidewall of the first outer I-beam 111. The second inner I-beam 122 and the second outer I-beam 112 are spaced apart. The first connecting piece 5 is a horizontally placed bolt. The first connecting piece 5 passes through the waist plate of the second outer I-beam 112 and the waist plate of the second inner I-beam 122 and fixes them. Similarly, the other first connecting pieces 5 pass through the waist plates of the first outer I-beam 111 and the first inner I-beam 121 and fix them. There are two first connecting pieces 5 on each second outer I-beam 112 and the second inner I-beam 122.

[0040] Reference Figure 4 and Figure 7 A second connecting member 8 is detachably fixed between two adjacent frames 1 in the vertical direction. The second connecting member 8 is a vertically installed bolt. The second connecting member 8 passes through the lower flange of the second outer I-beam 112 in the vertical direction and passes through the upper flange of another second outer I-beam 112 below the aforementioned second outer I-beam 112, thereby connecting and fixing the two second outer I-beams 112 belonging to two different outer support frames 11. Similarly, the second connecting member 8 is fixed on the first outer I-beam 111, the second inner I-beam 122, and the first inner I-beam 121, and is fixed in the aforementioned manner, thereby achieving the fixation between two adjacent layers of frames 1 in the vertical direction. It should be understood that the lowest horizontal frame 1 is fixed to the locking beam 6, which can be achieved by bolt connection or by welding.

[0041] Reference Figure 3 and Figure 7 The filling layer 4 comprises a solid structure formed after the concrete has hardened. Part of the edge of the filling layer 4 is flush with the top surface of the frame 1. The filling layer 4 covers the outer wall of the inner support frame 12 and the inner side of the outer support frame 11. The filling layer 4 fills the space between the coal bunker wall 9 and the frame 1, and also fills the area between the locking beam 6 and the coal bunker wall 9. The area between the inner support frame 12 and the outer support frame 11 has been filled by the filling layer 4. The top of the filling layer 4 extends to the top of the coal bunker wall 9 and slopes towards the top surface of the highest horizontally positioned frame 1. The bottom edge of the slope formed by the filling layer 4 above the frame 1 is located on the top surface of the highest horizontally positioned inner support frame 12.

[0042] Reference Figure 3 and Figure 7 The reinforcement 3 includes a connecting end 31 bolted to the frame 1 and a fixing end 32 for extending into the filling layer 4 and bending. The connecting end 31 passes through the waist plate of the outer support frame 11 laterally and is bolted to the corresponding waist plate. The fixing end 32 extends into the filling layer 4 outside the frame 1 and extends vertically downward.

[0043] In this embodiment, the frame 1 fixed to the locking beam 6 reduces the direct impact of the coal flow on the bottom of the coal bunker 9 and can provide support for the filling layer 4, reducing the possibility of the filling layer 4 breaking due to the impact of the coal flow. Even if the filling layer 4 breaks under long-term impact, it can still provide a buffering effect on the coal flow. Furthermore, the frame 1 can block the broken filling layer 4 between the locking beam 6 and the wall of the coal bunker 9, extending its service life.
