Description

Technical Field

[0001] This utility model relates to the field of molten iron ladle transfer technology, specifically a molten iron ladle transfer tractor with a residue cleaning structure. Background Technology

[0002] In the molten iron transfer process in the metallurgical and casting industries, molten iron ladles are usually moved and dumped by gantry cranes. However, the range of motion of such cranes is limited by tracks or fixed positions, making it impossible to flexibly unload at fixed points or remove slag en route. In addition, although traditional tractors have a certain degree of mobility, their simple structure lacks the functions of automatic tilting of molten iron ladles and slag removal. As a result, slag removal, dumping, and table cleaning cannot be completed simultaneously during the transfer process, requiring manual intervention or secondary lifting, which is inefficient and poses safety hazards.

[0003] Meanwhile, most transfer equipment only focuses on "movement stability" and has not solved the core problem of "separation of transfer, dumping and cleaning functions". For example, the "Tractor for Molten Iron Ladle" with publication number CN208408530U effectively reduces equipment investment costs and improves straight-line running stability by using an agricultural tractor body as a power source, combined with track guidance and reinforced front axle design, and avoids damage to molten iron ladles caused by debris bumps. However, its function is limited to the carrying and moving of molten iron ladles. Molten iron dumping still needs to rely on external hoisting equipment or dumping mechanisms at fixed workstations, and cannot realize flexible unloading at multiple workstations in the workshop.

[0004] Therefore, we propose a ladle transfer tractor with a slag removal structure. Utility Model Content

[0005] The purpose of this invention is to provide a ladle transfer tractor with a residue cleaning structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ladle transfer tractor with a slag cleaning structure, including a traction platform, a tilting platform installed on the top of the traction platform, and the tilting platform being rotatably connected to the traction platform, an arc plate being rolledly connected to the top of the tilting platform, and support positioning frames symmetrically arranged on the top of the traction platform and on both sides of the arc plate, with half-tooth sleeves movably connected to the opposite surfaces of the support positioning frames on both sides, and the half-tooth sleeves engaging with gear columns arranged on both sides of the ladle;

[0007] One side of the semi-tooth sleeve is a concave arc-shaped block with teeth, and the other side passes through the support positioning frame and is fitted with a gear. A transmission component is installed on one side of the support positioning frame, and a locking component is installed on the other support positioning frame. The transmission component includes a drive motor, a reducer and a gear. By meshing with the gear on the side of the semi-tooth sleeve, it drives the molten iron ladle placed on the top of the arc plate to rotate and pour the material.

[0008] Furthermore, the locking assembly includes an electric push rod and a toothed block corresponding to the gear teeth. The toothed block is welded to the end of the electric push rod to engage with the gear on one side of the half-tooth sleeve, thereby completing the rotation limit of the molten iron ladle placed on the top of the arc plate.

[0009] Furthermore, hydraulic drive components are evenly and symmetrically installed on both sides of the traction platform. The hydraulic drive components include a hydraulic pump, a hydraulic cylinder, and related connecting pipelines. A sliding plate is slidably connected inside the traction platform, and the hydraulic cylinder is correspondingly connected to the sliding plate.

[0010] Furthermore, a deflection block is installed at the bottom of the tilting platform and inside the traction platform, and the deflection block has a slot to engage with the sliding plate.

[0011] Furthermore, the top two sides of the tilting table are symmetrically connected to discharge side support plates, and side stops are correspondingly installed on the external traction platform of the discharge side support plates. Holes and locking bolts are provided on the rotation axis of the discharge side support plates, and the locking bolts pass through the holes on the tilting table and the holes on the discharge side support plates to complete the locking.

[0012] Furthermore, the inner wall of the discharge side support plate is provided with a protrusion, and the side of the tilting table is provided with a push shovel, the bottom groove of the push shovel abutting against the protrusion on the discharge side support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the traction platform conveyor, with the entire tilting platform as the carrier, can simultaneously carry out slag removal operations during the transfer of molten iron ladles, and can achieve fixed-point, automatic, and efficient slag unloading, while increasing the entire molten iron ladle tilting range. The hydraulic drive component set at the bottom of the traction platform drives the sliding plate to move, controlling the entire tilting platform to tilt at a fixed angle, while preventing abnormal rotation of the tilting platform. The traction platform is equipped with side guards for stability, and works in conjunction with the transmission component and locking component on the support positioning frame to complete the automatic tilting of the molten iron ladle on the tilting platform, realizing the expansion of the traction vehicle's operating functions and improving the overall operational flexibility;

[0014] The rotating support plate on the discharge side of the tilting platform enables the dumping of slag. During the resetting process, the pushing shovel can also impact and scrape the residue left on the dumping side of the molten iron ladle, and the repeated opening and closing completes the cleaning of the entire top surface of the tilting platform.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A tractor-trailer for transferring molten iron ladles with a slag removal mechanism, such as... Figure 1 and Figure 2 As shown, it includes a traction platform 1, which serves as the overall load-bearing foundation. A tilting platform 3 is installed on its top via a rotating shaft structure, allowing the tilting platform 3 to rotate relative to the traction platform 1.

[0025] like Figure 6 As shown, the top of the tilting table 3 is connected to an arc plate 4 by a ball or pulley mechanism. The arc plate 4 is used to place the molten iron ladle and the rolling connection reduces friction, making it easy for the molten iron ladle to rotate smoothly when tilting.

[0026] like Figure 3 As shown, support positioning frames 5 are symmetrically fixed on the top of the traction table 1 and on both sides of the arc plate 4. The opposite surfaces of the support positioning frames 5 on both sides are movably connected to the semi-tooth sleeves 6 through bearings. The semi-tooth sleeves 6 are designed as concave arc blocks on one side and have teeth on the inner wall, which are used to mesh and engage with the gear columns set on both sides of the molten iron ladle to achieve stable fixation and transmission of the molten iron ladle.

[0027] The other side of the half-tooth sleeve 6 passes through the support positioning frame 5 and is fitted with a gear. A transmission component 7 is installed on one side of the support positioning frame 5. The transmission component 7 includes a drive motor, a reducer and a transmission gear. The drive motor adjusts the output speed and torque through the reducer. The transmission gear meshes with the gear on the side of the half-tooth sleeve 6, thereby driving the half-tooth sleeve 6 to rotate, which in turn drives the molten iron ladle placed on the top of the arc plate 4 to rotate and pour the material.

[0028] On the other side, a locking assembly 8 is installed on the positioning frame 5. The locking assembly 8 includes an electric push rod and a tooth block corresponding to the gear teeth. The tooth block is welded to the end of the electric push rod. Through the extension and retraction of the electric push rod, the tooth block is engaged or disengaged from the gear on the half-tooth sleeve 6, thereby limiting and fixing the molten iron ladle when it rotates, and preventing accidental rotation.

[0029] Hydraulic drive components 11 are evenly and symmetrically installed on both sides of the traction platform 1. Each hydraulic drive component 11 includes a hydraulic pump, a hydraulic cylinder, and related connecting pipes. A sliding plate 12 is slidably connected inside the traction platform 1, and the output end of the hydraulic cylinder is correspondingly connected to the sliding plate 12. Figure 4 and Figure 5 As shown, the reciprocating motion of the slide plate 12 is controlled by hydraulic drive. A deflector block 13 is installed at the bottom of the tilting table 3 and inside the traction table 1. The deflector block 13 has a slot and is engaged with the end of the slide plate 12. When the hydraulic drive assembly 11 is working, it pushes the slide plate 12 to move. The deflector block 13 drives the tilting table 3 to tilt at a certain angle, realizing the lateral tilting of the molten iron ladle. At the same time, the self-locking function of the hydraulic system can prevent the tilting table 3 from rotating abnormally.

[0030] The top two sides of the tilting table 3 are symmetrically connected to the discharge side support plate 9. The discharge side support plate 9 is connected to the tilting table 3 through the central axis and can rotate around the central axis. The traction table 1 outside the discharge side support plate 9 is equipped with a side stop 2 to limit the rotation range of the discharge side support plate 9 and enhance the overall stability. The rotation central axis of the discharge side support plate 9 is provided with a hole, and a locking bolt 10 is used in conjunction. The locking bolt 10 passes through the hole on the tilting table 3 and the hole on the discharge side support plate 9 to lock the discharge side support plate 9 and prevent it from being accidentally unfolded during the transfer process.

[0031] The inner wall of the discharge side support plate 9 is provided with a protruding structure. The side of the tilting table 3 is fixed with a push shovel 14. The bottom of the push shovel 14 is designed with a groove that abuts against the protrusion on the discharge side support plate 9. When the discharge side support plate 9 is rotated and unfolded, the push shovel 14 moves accordingly. During the reset process, the interaction between the protrusion and the groove impacts and scrapes the residue left on the side of the molten iron ladle, thus achieving automatic cleaning. By repeatedly opening and closing the discharge side support plate 9, the cleaning work of the entire top surface of the tilting table 3 can be completed.

[0032] The working principle of this utility model is as follows: During the transfer of molten iron ladle, the traction platform 1 is moved by vehicle traction, the molten iron ladle is placed on the arc plate 4, and is fixed by the meshing of the molten iron ladle gear column with the half-tooth sleeve 6. When it is necessary to pour material or unload slag, the transmission component 7 is started, driving the half-tooth sleeve 6 to rotate, causing the molten iron ladle to tilt and pour material.

[0033] During rotation, the locking component 8 must be used to disengage the locking half of the toothed sleeve 6 to ensure operational safety. At the same time, the discharge side support plate 9 unfolds in the early stage of dumping to assist the slag to roll down. The hydraulic drive component 11 controls the overall tilting of the tilting table 3 to expand the dumping range, realize fixed-point and automatic slag unloading, and automatically clean the residual slag by pushing the shovel 14 when the discharge side support plate 9 is reset, thereby improving the overall efficiency and cleanliness.
