Description

Technical Field

[0001] This utility model relates to the field of molten iron ladle cleaning technology, and in particular to a molten iron ladle pouring car that facilitates the cleaning of residues inside the molten iron ladle. Background Technology

[0002] A ladle is a specialized container used in the iron and steel metallurgy and casting industries to hold, transfer, and pour molten iron (or steel) at high temperatures. It is a key transfer tool connecting the ironmaking, steelmaking, and casting processes. Its basic structure typically includes a ladle body with high-temperature and corrosion resistance, a support frame or rotating shaft structure to support the ladle body and facilitate pouring, and a movable walking mechanism. In the production process, the ladle is used to collect molten iron from the blast furnace tapping area and transfer it to the steelmaking furnace for steelmaking operations, or directly to the foundry workshop where the molten iron is poured into casting molds to complete the casting process.

[0003] In the actual operation cycle of molten iron ladles, after each filling and pouring of high-temperature molten iron, solidified iron residue is easily left on the bottom and inner wall. This residue is formed by the solidification of molten iron that has not been completely poured out. Currently, common molten iron ladle pouring cars only have basic functions of molten iron transfer and pouring, and lack a targeted residue cleaning mechanism. As a result, the residue cannot be removed in a timely and effective manner. When the residual residue is filled again, the solidified iron breaks off and mixes with the molten iron, causing uneven composition. This leads to defects such as porosity and slag inclusions in the castings, and can also cause precision castings to be scrapped.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a ladle pouring car that facilitates the cleaning of residue inside the ladle, thereby solving the aforementioned technical defects.

[0006] The following technical solution achieves the following: a molten iron ladle pouring car for easy cleaning of residue inside the ladle, comprising a mobile car body, a fixed frame fixedly installed on one side of the mobile car body, and a U-shaped frame movably installed on the fixed frame, a ladle being arranged inside the U-shaped frame, and clamping plates symmetrically arranged on both sides of the ladle, with clamping sleeves rotatably connected to opposite sides of the clamping plates, and deflection shafts fixedly connected to both sides of the ladle, and a slag removal assembly for cleaning the inner wall of the ladle being installed on the fixed frame.

[0007] Preferably, the fixed frame is slidably connected to the U-shaped frame via a fixedly installed vertical rod, the fixed frame is rotatably connected to a lead screw threadedly connected to the U-shaped frame, and a geared motor for driving the lead screw to rotate is installed on the fixed frame via bolts.

[0008] Preferably, a guide rod is fixedly connected to the clamping plate and slidably connected to the U-shaped frame, and a hydraulic cylinder is installed on the U-shaped frame to drive the corresponding clamping plate to move. A second geared motor for driving the corresponding clamping sleeve to rotate is installed on one set of the clamping plates by bolts.

[0009] Preferably, the inside of the clamping sleeve has a frustum-shaped structure, and the inside of the clamping sleeve is provided with a plurality of L-shaped clamping blocks arranged in a ring array. A convex block is fixedly connected to the L-shaped clamping block, and a convex groove is opened on the conical inner wall of the clamping sleeve to slide and connect with the corresponding convex block.

[0010] Preferably, a reset plate is fixedly connected inside the clamping sleeve by a spring, and one side of the reset plate abuts against multiple L-shaped clamping blocks under the elastic force of the spring.

[0011] Preferably, the slag removal assembly includes a horizontal plate fixedly connected to a fixed frame, a rotating motor is bolted to the horizontal plate, a rotating rod is mounted on the output shaft of the rotating motor, a mounting frame is fixedly connected to the rotating rod, and scrapers are mounted on both sides and the bottom of the mounting frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes the relative movement of two sets of clamping plates, combined with the conical structure inside the clamping sleeve, L-shaped clamping blocks, and a reset plate, along with the lifting movement of the U-shaped frame. This allows for adaptive movement of ladle deflection shafts of different sizes, ensuring stable clamping of the ladle while facilitating quick ladle replacement. Furthermore, the lifting movement of the ladle causes multiple scrapers in different directions to extend into the ladle, achieving comprehensive scraping of residue from the inner annular wall and bottom of the ladle.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-5 As shown, the existing molten iron ladle pouring cars only have basic functions of molten iron transfer and dumping, and lack a targeted residue cleaning mechanism, resulting in the inability to remove residue in a timely and effective manner. The following solutions can be used to address this problem.

[0025] This embodiment of a molten iron ladle pouring car for easy cleaning of residue inside the ladle includes a movable car body 1 for driving the movement of the clamped and fixed ladle, thereby completing the transfer and casting of molten iron. A fixed frame 11 is fixedly installed on one side of the movable car body 1, and a U-shaped frame 12 is movably installed on the fixed frame 11. The ladle is arranged inside the U-shaped frame 12, and clamping plates 13 are symmetrically arranged on both sides of the ladle. Clamping sleeves 14 are rotatably connected to the opposite sides of the clamping plates 13. Deflection shafts are fixedly connected to both sides of the ladle. By using the relative movement of the two sets of clamping plates 13, combined with the insertion and contact of the clamping sleeves 14 and the corresponding deflection shafts, and in conjunction with the lifting and lowering movement of the U-shaped frame 12, the ladle can be quickly and easily replaced. A slag removal component for cleaning the inner wall of the ladle is installed on the fixed frame 11.

[0026] The fixed frame 11 is slidably connected to the U-shaped frame 12 by a fixedly installed vertical rod. The vertical rod is set to increase the stability of the lifting and lowering movement of the U-shaped frame 12. The fixed frame 11 is rotatably connected to the lead screw 15, which is threadedly connected to the U-shaped frame 12. The fixed frame 11 is bolted to a geared motor 16 that drives the lead screw 15 to rotate. The geared motor 16 drives the lead screw 15 to rotate. Combined with the threaded connection between the lead screw 15 and the U-shaped frame 12, the U-shaped frame 12 carries the clamped ladle and moves up and down.

[0027] A guide rod is fixedly connected to the clamping plate 13 and slidably connected to the U-shaped frame 12 to increase the sliding stability between the clamping plate 13 and the U-shaped frame 12. A hydraulic cylinder 17 is installed on the U-shaped frame 12 to drive the corresponding clamping plate 13 to move. Two sets of hydraulic cylinders 17 push the corresponding clamping plate 13 to move, so that the two sets of clamping plates 13 move synchronously closer to or away from the ladle, realizing the centering clamping of ladles of different sizes and avoiding interference with the operation of the slag removal components. A second geared motor 18 is installed on one set of clamping plates 13 by bolts to drive the corresponding clamping sleeve 14 to rotate. The second geared motor 18 drives the corresponding clamping sleeve 14 to deflect, which drives the ladle to deflect, so as to collect molten iron and pour it into the mold to complete the casting.

[0028] The clamping sleeve 14 has a frustum-shaped internal structure. Multiple L-shaped clamping blocks 19 arranged in a circular array are provided inside the clamping sleeve 14. A convex block is fixedly connected to the L-shaped clamping block 19. A convex groove is opened on the conical inner wall of the clamping sleeve 14 to slide and connect with the corresponding convex block. The cooperation between the convex block and the convex groove is used to realize the inclined sliding installation of the L-shaped clamping block 19. The L-shaped clamping block 19 is divided into an abutting section and a clamping section. The convex block is installed in the clamping section area.

[0029] When the deflection shafts on both sides of the ladle are inserted into the corresponding clamping sleeves 14, the ends of the deflection shafts abut against the contact sections of the L-shaped clamping blocks 19, thereby pushing multiple L-shaped clamping blocks 19 to move synchronously within the clamping sleeves 14. Combined with the sliding installation of the clamping sections of the L-shaped clamping blocks 19 on the conical inner wall of the clamping sleeves 14, multiple L-shaped clamping blocks 19 are simultaneously moved relative to each other to clamp the deflection shafts, thereby achieving the clamping and fixing of deflection shafts of different sizes in the ladle.

[0030] A reset plate 111 is fixedly connected inside the clamping sleeve 14 by a spring 110. One side of the reset plate 111 abuts against multiple L-shaped clamping blocks 19 under the elastic force of the spring 110. When the two sets of clamping plates 13 move away from each other, when the deflection shafts on both sides of the ladle move out of the corresponding clamping sleeve 14, the elastic force of the spring 110 pushes the reset plate 111 that abuts against multiple L-shaped clamping blocks 19 to move, so that multiple L-shaped clamping blocks 19 achieve the reset effect of moving away from each other. Thus, when fixing the ladle, the docking and clamping fixing of the deflection shafts on both sides of the ladle with the corresponding clamping sleeve 14 is completed quickly.

[0031] The slag removal assembly includes a horizontal plate 2 fixedly connected to a fixed frame 11. A rotating motor 21 is bolted to the horizontal plate 2, and a rotating rod 22 is mounted on the output shaft of the rotating motor 21. A mounting frame 23 is fixedly connected to the rotating rod 22, and scrapers 24 are mounted on both sides and the bottom of the mounting frame 23. The ladle is raised by rotating the lead screw 15, and the mounting frame 23 is inserted into the ladle. The rotating motor 21 drives the rotating rod 22 to rotate the mounting frame 23. The scrapers 24 on both sides of the mounting frame 23 scrape off the residue on the inner wall of the ladle, and the scraper 24 at the bottom of the mounting frame 23 scrapes off the residue at the bottom of the ladle. After all the residue on the inner wall of the ladle is scraped off, the ladle descends and separates from the scrapers 24 on the mounting frame 23. Then, the ladle is deflected again by the reduction motor 18, and the residue is poured out, completing the complete cleaning of the residue.

[0032] The working process and principle of this utility model are as follows:

[0033] The present invention uses two sets of hydraulic cylinders 17 to push the corresponding clamping plates 13 to move, so that the two sets of clamping plates 13 move closer to the ladle at the same time, causing the deflection shafts on both sides of the ladle to be inserted into the corresponding clamping sleeves 14. The ends of the deflection shafts abut against the contact sections of the L-shaped clamping blocks 19, thereby pushing multiple L-shaped clamping blocks 19 to move within the clamping sleeves 14. Combined with the sliding installation of the L-shaped clamping blocks 19 on the conical inner wall of the clamping sleeves 14, multiple L-shaped clamping blocks 19 are simultaneously moved relative to each other to clamp the deflection shafts, thereby achieving the clamping and fixing of deflection shafts of different sizes in the ladle.

[0034] The first geared motor 16 drives the lead screw 15 to rotate. Combined with the threaded connection between the lead screw 15 and the U-shaped frame 12, the U-shaped frame 12 carries the ladle and moves upward. Then the moving car body 1 carries the ladle to the collection area to collect and transfer the molten iron for pouring. The second geared motor 18 drives the corresponding clamping sleeve 14 to deflect, which in turn causes the ladle to deflect and pour the collected molten iron into the mold for casting.

[0035] The screw 15 rotates, causing the clamped ladle to rise continuously, resulting in the mounting frame 23 being inserted into the ladle. The rotating motor 21 drives the rotating rod 22 to rotate the mounting frame 23. The scrapers 24 on both sides of the mounting frame 23 scrape off the residue on the inner wall of the ladle, and the scraper 24 at the bottom of the mounting frame 23 scrapes off the residue at the bottom of the ladle. After all the residue on the inner wall of the ladle is scraped off, the ladle descends and separates from the scrapers 24 on the mounting frame 23. The reduction motor 18 then drives the ladle to deflect, pouring out the residue and completing the complete cleaning of the residue.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
