Description

Technical Field

[0001] This utility model belongs to the field of converter blowing track cleaning technology, and in particular relates to a track sweeper suitable for converter ladle cars. Background Technology

[0002] Steelmaking involves removing impurities from pig iron and scrap steel through oxygen blowing in a converter, and adding appropriate alloying elements according to the steel grade to create steel with high strength, high toughness, and special properties. During the converter blowing process, impurities in the steel are sprayed by the airflow and adhere to the surface of the flue heating pipes and furnace skirts. The adhered slag falls off due to thermal expansion and contraction, and some slag chunks fall onto the ladle car tracks that transport high-temperature molten steel and slag under the furnace, obstructing the normal passage of the ladle cars. Slag chunks exceeding 200 kg are cleaned by a forklift coordinated according to production conditions, while smaller slag chunks are cleaned using the track sweepers equipped on the ladle cars themselves. Currently, the track sweepers equipped on the ladle cars are welded steel plate structures, which can only clean slag chunks but cannot clean slag particles on the track surface. The accumulation of slag particles on the track surface causes frequent deformation of the ladle car track sweepers, and even weld breakage and detachment. Utility Model Content

[0003] The purpose of this invention is to provide a rail sweeper suitable for converter ladle cars, solving the problem that existing ladle car rail sweepers cannot clean steel slag particles from the track surface.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rail sweeper suitable for converter ladle cars includes stiffener plate one and stiffener plate two. Stiffener plate one is a rectangular plate with bolt holes at both ends of the bottom. Stiffener plate two is an irregular L-shaped plate, composed of a rectangular plate and a right-angled triangular plate. The right-angled side of the bottom of the rectangular plate connects to the right-angled side of the right-angled triangular plate, and the bottom of the rectangular plate is flush with the bottom of the right-angled triangular plate. Stiffener plate two is vertically fixed to both ends and the middle of one side of stiffener plate one. Stiffener plate four is welded between the top rectangular plates of adjacent stiffener plate two. A top plate is vertically welded to the hypotenuse of the triangular plate at the bottom of stiffener plate two. Stiffener plate three is vertically welded to both ends of the other side of stiffener plate one. Stiffener plate one, stiffener plate two, and stiffener plate three are all the same length. The top and bottom of stiffener plate one, stiffener plate two, and stiffener plate three are flush. Stiffener plate one is located between stiffener plate three and is connected to a pressure plate in parallel by bolts. A steel wire rope is pressed between stiffener plate one and the pressure plate. The bottom of stiffener plate one and the pressure plate are flush, and the bottom of the steel wire rope is lower than the height of the pressure plate.

[0005] Preferably, the top of the fourth stiffener is flush with the top of the rectangular plate of the second stiffener, and the bottom of the fourth stiffener is flush with the top of the bottom triangular plate of the second stiffener.

[0006] Preferably, the top of the top plate is flush with the top of the bottom triangular plate of the second stiffener, and the bottom of the top plate is flush with the bottom of the bottom triangular plate of the second stiffener.

[0007] The beneficial effects achieved by this utility model are as follows: (1) The steel slag blocks are separated to both sides of the track by the top plate, and the steel wire rope cleans the small steel slag particles on the track surface. The steel slag particles on the track surface are cleaned in time to avoid the accumulation of steel slag particles and prevent the track sweeper from deforming and falling off frequently. (2) The steel wire rope is tightened by bolted connection of pressure plate, which facilitates adjustment of the steel wire rope height and ensures effective cleaning of steel slag particles.

[0010] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1-8As shown, a rail sweeper suitable for converter ladle cars includes stiffener plate 1 and stiffener plate 2. Stiffener plate 1 is a rectangular plate with bolt holes at both ends of the bottom. Stiffener plate 2 is an irregular L-shaped plate, composed of a rectangular plate and a right-angled triangular plate. The right-angled side of the bottom of the rectangular plate connects to the right-angled side of the right-angled triangular plate, and the bottom of the rectangular plate is flush with the bottom of the right-angled triangular plate. Stiffener plate 2 is vertically fixed to both ends and the middle of one side of stiffener plate 1. Stiffener plate 4 is welded between the top rectangular plates of adjacent stiffener plates 2. The top of stiffener plate 4 is flush with the top of the rectangular plate of stiffener plate 2, and the bottom of stiffener plate 4 is flush with the top of the bottom triangular plate of stiffener plate 2. A top plate 5 is vertically welded to the hypotenuse of the bottom triangular plate of stiffener plate 2. The top of the top plate 5 is connected to the stiffener plate 2. The top of the bottom triangular plate of stiffener 2 is flush with the bottom of the top plate 5, and the bottom of the top plate 5 is flush with the bottom of the bottom triangular plate of stiffener 2. Stiffener 3 is welded vertically to both ends of the other side of stiffener 1. The lengths of stiffener 1, stiffener 2, and stiffener 3 are all the same. The tops and bottoms of stiffener 1, stiffener 2, and stiffener 3 are flush with each other. Stiffener 1 is located between stiffener 3 and pressure plate 6 is connected in parallel by bolts. Steel wire rope 7 is pressed between stiffener 1 and pressure plate 6. The bottom of stiffener 1 and pressure plate 6 are flush with each other. The bottom of steel wire rope 7 is lower than the height of pressure plate 6. The use of multi-stiffener welding improves the stability of the device. The top plate separates the steel slag blocks to both sides of the track, ensuring the track is clean and preventing the ladle car from overturning. The steel wire rope sweeps away small steel slag particles to prevent their accumulation.

[0012] Working principle: such as Figure 2 , 9 As shown, the top of the rail sweeper is welded to the four corners of the lower end face of the main beam of the ladle car. When the ladle car is running, the top plate 5 of the rail sweeper separates the steel slag blocks to both sides of the track. The wire rope 7 sweeps the small steel slag particles on the track surface. The stiffening plate 4 prevents the steel slag blocks from falling into the rail sweeper. When the bottom of the wire rope 7 is worn and affects the sweeping, the pressure plate 6 is removed, the wire rope 7 is moved to a suitable height, and the pressure plate 6 is pressed again to ensure that the height of the wire rope is appropriate, so as to achieve effective and timely sweeping of steel slag particles.
