Description

Technical Field

[0001] This utility model relates to the field of industrial building structure technology, specifically a reinforced concrete double-sided self-weight coal unloading trough. Background Technology

[0002] Currently, coal-fired power plants remain the primary source of electricity and steam for industrial use in China. Off-site coal transportation to power plants utilizes land and water transport. Coal can be transferred between plants by vehicle or via fully enclosed belt conveyors. In the latter case, coal is conveyed via belt conveyor and trestle to the dry coal shed unloading platform, and then unloaded into the dry coal shed for storage via unloading troughs. However, the existing unloading troughs have an unreasonable structural design and poor stability. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a reinforced concrete double-sided self-weight coal unloading trough, which can realize reliable and stable coal unloading operation.

[0004] The technical solution is as follows: a double-sided self-weight coal unloading trough structure, which includes a coal unloading trough, characterized in that two coal unloading troughs are provided and are made of reinforced concrete, the tops of the two coal unloading troughs are suspended from the bottom of the coal unloading platform, the bottoms of the two coal unloading troughs are respectively supported by bottom support beams on both sides, the bottom support beams are the top beams of the coal yard retaining wall, a tie beam is provided between the two coal yard retaining walls, and the bottom plate of the coal unloading trough has an angle of not less than 60° with the horizontal plane.

[0005] A further feature is that a top support beam is provided at the bottom of the coal unloading platform, and the side walls of the coal unloading trough are suspended from the top support beam by hanging rods; The bottom plate of the coal unloading trough and the bottom of the coal unloading platform, as well as the side walls of the coal unloading trough and the top support beam, are all integrally cast. The inner sides of the bottom plate and the inner sides of the side walls of the coal unloading trough are both lined with wear-resistant steel plates.

[0006] With the adoption of this utility model, the top of the coal unloading trough of the reinforced concrete structure is suspended and the bottom is supported. The tie beam between the bottom support beams ensures the stability of the coal unloading troughs on both sides. The coal is unloaded into the lower coal unloading trough by the unloader. The coal can slide into the coal storage yards on both sides stably by its own weight without shaking. Attached Figure Description

[0007] Figure 1 This is a top view of the present invention; Figure 2 This is a bottom view of the present invention; Figure 3 for Figure 1 Sectional view along the AA direction; Figure 4 for Figure 3 Enlarged view of the cross section along the BB direction. Detailed Implementation

[0008] See Figures 1 to 4 As shown, a double-sided self-weight coal unloading trough structure includes two coal unloading troughs 1, which are made of reinforced concrete. The tops of the two coal unloading troughs 1 are suspended from the bottom of the coal unloading platform 2. The bottoms of the two coal unloading troughs 1 are respectively supported by bottom support beams 3 on both sides. The bottom support beams 3 are the top beams of the coal yard retaining walls 4. Tie beams 5 are set between the coal yard retaining walls 4 on both sides. The bottom plate of the coal unloading trough 1 has an angle of not less than 60° with the horizontal plane. The coal can slide naturally to the coal yards on both sides by gravity.

[0009] The bottom of the coal unloading platform 2 is provided with a top support beam 6. The side wall of the coal unloading trough 1 is suspended from the top support beam 6 by a hanger 7. Two plow holes 11 corresponding to the coal unloading trough 1 are opened on the coal unloading platform 2. The bottom plate 8 of the coal unloading trough 1 and the bottom of the coal unloading platform 2, and the side wall 9 of the coal unloading trough 1 and the top support beam 6 are all integrally cast. The side wall of the coal unloading trough 1 should be able to prevent coal from falling outside the coal storage area.

[0010] The inner sides of the bottom plate 8 and the inner sides of the side wall 9 of the coal unloading trough 1 are both lined with wear-resistant steel plates 10 to prevent long-term friction of the flowing coal from damaging the coal unloading trough 1.

[0011] In specific implementation: determine the position of the side wall and top of the bottom plate of the unloading chute based on the opening size of the plow's discharge port provided by the coal conveying specialist; arrange the top support beam and bottom tie beam of the unloading chute based on the position of the side wall; determine the bottom position and top inflection point position of the bottom plate of the unloading chute based on the elevation of the unloading platform and the elevation of the retaining wall, ensuring that the angle between the bottom plate and the horizontal plane is not less than 60 degrees; determine the height of the wear-resistant inner lining of the side wall of the unloading chute based on the height of the transported material; determine the thickness of the wear-resistant steel plate lining based on the intensity of material transport; determine the thickness of the bottom plate of the unloading chute based on the weight of the transported material and the width of the coal chute; determine the cross-sectional area of ​​the side wall suspension bars based on the dead load and live load of the unloading chute (without considering the effect of the bottom support point of the unloading chute).
