Abstract
Description
Technical Field
[0001] This utility model belongs to the field of converter blowing track cleaning technology, and in particular relates to a ladle car track sweeper that is easy to disassemble and assemble. Background Technology
[0002] During the converter's blowing process, impurities in the steel are sprayed and adhere to the surface of the flue heating pipes and furnace skirts. The adhering slag detaches due to thermal expansion and contraction, and some slag chunks fall onto the ladle car tracks that transport high-temperature molten steel and slag below the furnace, obstructing the normal passage of the ladle cars. Slag chunks exceeding 200 kg are cleaned by a loader in coordination with production conditions, while smaller slag chunks are cleaned using the ladle car's own rail sweeper. Currently, the ladle car's rail sweeper is a welded steel plate structure; if the bottom of the sweeper is damaged, replacement is inconvenient, and replacing the entire sweeper is both time-consuming and wasteful of steel plates, resulting in high maintenance costs. Utility Model Content
[0003] The purpose of this utility model is to provide a ladle car rail sweeper that is easy to disassemble and assemble, solving the problem that existing ladle car rail sweepers are inconvenient to replace when damaged.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A steel ladle car rail sweeper that is easy to assemble and disassemble includes an upper section and a lower section. The upper section includes a first stiffener plate and a second stiffener plate. The two ends and the middle of the second stiffener plate are vertically welded to the first stiffener plate, forming a grid pattern when viewed from the top. The bottom of the first stiffener plate and the second stiffener plate are fixed to the same inclined plate. The bottom end of the inclined plate is flat, and the top surface is inclined. A pin hole is opened on one side of the inclined plate. Through holes are opened on both sides of the bottom of the second stiffener plate. The lower section includes a top plate. A pin hole is opened on one side of the top plate. A support frame is welded to the middle of the bottom surface of the top plate. The support frame is truncated... The surface is cross-shaped. The bottom of the left and right sides of the top plate are vertically welded with stiffening plates three. The bottom of the front and rear sides of the top plate are vertically welded with stiffening plates four. The two ends of stiffening plates four are welded to the upper half of stiffening plates three on both sides. The bottom of the outer side of stiffening plates three on both sides is connected to pressure plates by bolts. The width of stiffening plates three and pressure plates is the same. The outer side of pressure plates is fixedly connected to plow-type shovel plates. A steel wire rope is pressed between the left stiffening plate three and the pressure plate. The bottom height of the steel wire rope is lower than the bottom height of the pressure plate. The inclined plate and the top plate are connected by wedge plates and fixed by pins.
[0005] Preferably, the wedge plate assembly includes a first wedge plate and a second wedge plate, with one end of the first wedge plate and the second wedge plate fixedly connected. Pin holes are provided at corresponding positions on the top and bottom of the first wedge plate and the second wedge plate. The top surface of the first wedge plate is flat and the bottom surface is inclined. The first wedge plate passes through the through hole at the bottom of the second rib plate and fits with the inclined plate. The second wedge plate is a flat plate and is fixedly connected to the top plate by a pin.
[0006] Preferably, the plow-type shovel is a right-angled triangular pyramid.
[0007] Preferably, the bolt holes of the two side stiffeners are oblong holes, which facilitates the adjustment of the height of the pressure plate. The height of the pressure plate directly affects the height of the plow blade, and the oblong holes are beneficial for adjusting the distance between the plow blade and the rail surface.
[0008] Preferably, a fifth stiffening plate is welded between the bottom of the two side stiffening plates.
[0009] Working principle: The upper section of the rail sweeper is welded to the four corners of the lower end face of the main beam of the ladle car. During the operation of the ladle car, the distance between the plow-type shovel and the rail surface is adjusted to about 20mm. The plow-type shovel separates the steel slag blocks to both sides of the rail. At the same time, the wire rope sweeps the small steel slag particles on the rail surface. When the bottom of the wire rope is worn and affects the sweeping, the pressure plate is removed and the height of the wire rope is adjusted to ensure that the height of the wire rope is appropriate. During the sweeping process, if the height of the plow-type shovel is not suitable, the height of the plow-type shovel is adjusted through the long oval bolt holes of the stiffener plate three.
[0010] The beneficial effects achieved by this utility model are: (1) The rail sweeper is divided into upper and lower sections, which are convenient for installation and disassembly. It is connected by wedge plates. The lower section can be quickly replaced after damage, which shortens maintenance time, reduces maintenance costs, and improves work efficiency. (2) The steel slag blocks are separated to both sides of the track by the plow-type shovel plate, and the steel wire rope cleans the small steel slag particles on the track surface. The steel slag on the track surface is cleaned in time, which extends the service life of the track and wheel set, and at the same time avoids the steel ladle car from crushing the steel slag blocks and causing derailment.
