Description

Technical Field

[0001] This invention relates to the technical field of building structures, and in particular to a blast furnace tapping platform. Background Technology

[0002] The tapping platform is a crucial area for separating and collecting molten iron from slag in modern blast furnace smelting. It includes structures such as the main channel, iron channel, slag channel, and swing chute, all designed for this separation and collection. However, existing tapping platform structures suffer from several technical shortcomings. The current system uses deep beams as sidewalls for the channels, with slabs laid between them, forming a unified structure. The channels, subjected to the force of flowing molten iron and its high temperature, are prone to deformation, leading to platform cracking and concrete loosening. Due to production requirements, regular cleaning and replacement of the channels using heavy machinery is necessary, causing damage to structural components and significantly impacting the overall lifespan of the platform. This poses a potential hazard to blast furnace operations. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a blast furnace tapping platform to reduce the damage caused by the ditch system itself to the overall tapping platform, and to facilitate the replacement of the damaged ditch system.

[0004] The present invention provides a blast furnace tapping platform using the following technical solution:

[0005] A blast furnace tapping platform includes a platform body for supporting a trench system. The platform body includes platform frame columns and a trench system lower beam disposed on the platform frame columns. Supports are provided on both the frame body and the trench system lower beam. The supports are used to support the trench system. Platform plates are provided on the platform frame columns. The platform plates are used to restrict the lateral displacement of the trench system. The supports and platform plates provide three-sided support for the trench system.

[0006] Optionally, the beams below the trench system include transverse beams of the platform trench bottom frame, longitudinal beams of the platform trench bottom frame, and secondary beams of the platform trench bottom. The platform frame columns, transverse beams of the platform trench bottom frame, and longitudinal beams of the platform trench bottom frame form a frame with a rectangular cross-section.

[0007] Optionally, the secondary beam at the bottom of the platform trench is set on the longitudinal beam of the platform trench bottom frame or on the transverse beam of the platform trench bottom frame along the length of the trench system.

[0008] Optionally, it also includes a beam-on-column and a platform beam. The platform beam is mirror-image disposed on two platform frame columns along the width direction of the trench system. The beam-on-column is disposed on the transverse beam of the platform trench bottom frame. The two platform plates are correspondingly disposed on the beam-on-column and limit the transverse direction of the trench system.

[0009] Optionally, two secondary beams are provided at intervals along the width of the trench system and are located below the two side walls of the trench system in the transverse direction.

[0010] Optionally, the cross-section of the groove system is an H-shaped groove or a U-shaped groove.

[0011] Optionally, an oil paper is provided between the platform body and the trench system.

[0012] Optionally, the platform body is a concrete structure or a steel structure.

[0013] Optionally, the trench structure is a heat-resistant concrete structure or a steel structure.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects: by adopting a platform structure nested within the iron tapping area after the trench system is self-supporting, the problem of excessive difference between the horizontal load generated by the molten iron borne by the trench system and the platform displacement of the iron tapping area is solved. It also solves the problem of excessive difference between the expansion of the molten iron generated by the trench system during the production process and the expansion of the iron tapping area structure itself. Furthermore, it ensures that the damage to the trench system structure caused by the use of large mechanical equipment during the periodic replacement of materials inside the trench system due to process requirements does not affect the overall stability and durability of the iron tapping area platform structure itself.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0021] This invention discloses a blast furnace tapping platform.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A blast furnace tapping platform includes a platform body supporting a trough system 6. The platform body includes a frame body and secondary beams 4 at the bottom of the trough, both mounted on the frame body. Supports 7 are provided on both the frame body and the secondary beams 4, supporting the trough system 6. Platform plates 8 are provided on the frame body, limiting the lateral displacement of the trough system 6. The supports 7 and platform plates 8 provide three-sided support for the trough system 6. By employing a platform structure where the trough system 6 is self-supporting and nested within the tapping area, the problem of excessive difference between the horizontal load generated by the molten iron and the platform displacement of the tapping area is solved. It also solves the problem of excessive difference between the expansion of the molten iron during production and the expansion of the tapping area structure itself. Furthermore, it ensures that the damage to the trough system 6 caused by the periodic replacement of internal materials during process requirements does not affect the overall stability and durability of the tapping area platform structure.

[0023] The trench system 6 is constructed of heat-resistant concrete or steel. The cross-section of the trench system 6 is either an H-shaped or U-shaped trench. In this embodiment, the cross-section of the trench system 6 is an H-shaped trench.

[0024] The platform itself is a concrete or steel structure. The frame body includes platform frame columns 1, platform trench bottom frame transverse beams 2, and platform trench bottom frame longitudinal beams 3, which together form a rectangular frame.

[0025] The secondary beam 4 at the bottom of the platform trench is set on the longitudinal beam 3 of the platform trench bottom frame.

[0026] It also includes a beam-on-column 5 and a platform beam 9. The platform beam 9 is mirrored along the width direction of the trench system 6 and is set on the two platform frame columns 1. The beam-on-column 5 is set on the transverse beam 2 of the platform trench bottom frame. The two platform plates 8 are correspondingly set on the beam-on-column 5 and limit the transverse direction of the trench system 6.

[0027] In this embodiment, the transverse beam 2 of the platform trench bottom frame, the longitudinal beam 3 of the platform trench bottom frame, and the secondary beam 4 of the platform trench bottom form the lower beam of the trench system 6.

[0028] Setting up piers 7 on the beam below the ditch system 6 can reduce the span of the bottom plate of the ditch system 6.

[0029] Reference Figure 2 and 4 The secondary beam 4 at the bottom of the platform trench is set along the length of the trench system 6 on the transverse beam 2 of the platform trench bottom frame.

[0030] Two secondary beams 4 are provided at intervals along the width direction of the trench system 6, and are located below the two side walls of the trench system 6 in the transverse direction.

[0031] To prevent the trench system 6 from shifting under load and causing the platform body to move, oil paper is installed between the platform body and the trench system 6.

[0032] When the trench system 6 is a precast component or a steel structure component, the frame body and the beams below the trench system 6 are constructed on-site first, while the trench system 6 is fabricated simultaneously. Then, the columns 5, platform slabs 8, and platform beams 9 near the trench system 6 are constructed. Finally, the trench system 6 is installed. This allows on-site construction and the fabrication of the precast trench system 6 to proceed simultaneously, reducing the amount of wet work, greatly shortening the construction cycle, and reducing construction auxiliary costs and project investment costs. When the trench system 6 is a cast-in-place component, the frame body and the beams below the trench system 6 are constructed on-site first, followed by the columns 5, platform slabs 8, platform beams 9, and the trench system 6 near the trench system 6.

[0033] The groove system 6 and the platform body are separate force-bearing systems, which facilitates the separation of the groove system 6 from the platform body.

[0034] By adopting a double-beam system consisting of the platform trench bottom frame transverse beam 2 and the platform plate 8 to support the trench system 6 of the blast furnace tapping area, the degree of mutual influence between the two under stress is improved, and the trench system 6 can be easily replaced after damage during the production process without causing collateral damage to the overall platform.

[0035] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
