[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0020] Reference Figure 1 and 2As shown, this embodiment discloses a quick reinforcement device for a converter flue transverse vehicle beam, wherein a traveling beam 1 is arranged on the transverse vehicle beam 2, and a column 5 to be removed is arranged below the transverse vehicle beam 2; specifically, the quick reinforcement device includes a plurality of groups of C-shaped hangers; and a group of C-shaped hangers is arranged above each column 5 to be removed; each group of C-shaped hangers includes two C-shaped hangers arranged oppositely, and the two C-shaped hangers are respectively arranged on both sides of the transverse vehicle beam 2; each C-shaped hanger includes a pad structure 3 and two C-shaped pallets 4; the C-shaped pallet 4 includes a top plate, The bottom plate and the connecting plate connecting the top plate and the bottom plate, the lower sides of the top plates of the two C-shaped pallets 4 are fixedly connected to the upper surface of the pad structure 3 (the opening direction of the C-shaped pallet 4 is toward the webs of the traveling beam 1 and the transverse vehicle beam 2), the pad structure 3 is arranged on the upper surface of the lower flange of the traveling beam 1 (the pad structure 3 can be directly placed on the upper surface of the lower flange of the traveling beam 1 without welding), the bottom plates of the two C-shaped pallets 4 are arranged below the upper flange of the transverse vehicle beam 2, and the vertical openings of the bottom plates of the two C-shaped pallets 4 are fixedly connected together with the webs of the transverse vehicle beam 2.

[0021] Specifically, through statistical calculations, the force on the front beam of the transverse car furnace is about 36 tons, and it is necessary to add more sets of C-type hangers on the travel track beam above the transverse car beam 2. After the columns under the transverse car beam 2 are removed, the average force on the C-type pallets of each C-type hanger is calculated to be 5 tons. Through calculations, the C-type pallets made of 50mm thick steel plates can meet the force requirements, which can greatly shorten the time for replacing the furnace body.

[0022] In the embodiment of the utility model, the pad structure 3 comprises a plurality of steel plates stacked up and down; the length of the pad structure 3 is 1 to 2 m, and the thickness of the C-type pallet 4 is 50 to 60 mm (e.g., 50 mm, 55 mm, 56 mm, or 60 mm, etc.); the lower sides of the top plates of the two C-type pallets 4 are respectively welded and fixed to the two sides of the upper surface of the pad structure 3; the vertical openings of the bottom plates of the two C-type pallets 4 (i.e., the side of the bottom plate of the C-type pallet 4 adjacent to the web of the transverse vehicle beam 2) are respectively welded and fixed to the web of the transverse vehicle beam 2. Specifically, the length of the pad structure 3 and the thickness of the C-type pallet 4 are generally set according to the model of the reinforced transverse vehicle beam and the weight of the flue facilities, which is equivalent to being set according to the weight of the matching transverse vehicle and flue ancillary equipment of the converter (100t, 120t, 150t).

[0023] Specifically, 8 C-shaped pallets 4 and 4 pad structures 3 are made of 50mm thick steel plates, and the tools are prepared in place; then, a 50mm (width) * 1500mm (length) steel plate is used as the steel plate of the pad structure 3 and is placed on the lower flange plate of the crane beam 1 corresponding to the column 5 to be removed (the pad structure 3 and the lower flange plate of the crane beam 1 do not need to be welded), and then the C-shaped pallets 4 are welded and installed on the pad structure 3 at the lower end of the crane beam, and the lower part of the C-shaped pallet 4 hooks the upper flange plate of the transverse vehicle beam 2, and the web of the transverse vehicle beam 2 and the vertical connection part of the C-shaped pallet 4 are firmly and reliably welded by electric welding, and the pad structure 3 and the C-shaped pallet 4 added to the crane beam 1 are firmly welded.

[0024] In addition, considering the weight of the equipment and facilities on the transverse trolley beam, in order to be safer and more reliable, a 10T winch (30T pulley block) can be installed on each of the 5F platform beams (at both ends directly above the transverse trolley furnace front beam). The two winches are hung on the side beams of the transverse trolley (close to the furnace front part), so that the weight of the equipment on the transverse trolley is mainly borne by the winch.
