Description

Technical Field

[0001] This utility model belongs to the technical field of ladle capping mechanism, specifically relating to a ladle capping device that can be quickly disassembled and assembled. Background Technology

[0002] In the steelmaking industry, the temperature and quality stability of molten steel are core elements for ensuring production efficiency and product quality. During transfer and processing, if the ladle is open, the temperature will drop sharply due to significant heat loss. Simultaneously, it is prone to oxidation with oxygen in the air, causing changes in the steel's composition and severely impacting the stability of subsequent smelting processes and the final steel quality. To address this issue, a ladle capping mechanism has been developed. This mechanism effectively prevents direct contact between the molten steel and the external environment by covering the ladle opening. This not only significantly reduces heat loss to maintain the steel temperature but also prevents oxidation, thus ensuring stable steel quality. Typically, a ladle capping mechanism consists of a cap, a drive mechanism, and a sealing structure. The cap provides physical isolation, the drive mechanism opens and closes the cap, and the sealing structure further enhances heat insulation and anti-oxidation effects.

[0003] While existing fixed ladle covering mechanisms can reduce heat loss to some extent, they often rely on welded or bolted connections. This design necessitates the use of cranes to lift the entire covering mechanism or disassemble numerous individual connectors during maintenance. This not only makes maintenance time-consuming and significantly extends equipment downtime but also drastically increases labor intensity due to the complexity of the operation, severely impacting the continuity of steel production. More importantly, under the frequent thermal shock conditions of steel production, the bolts used for fastening are prone to seizing due to drastic temperature changes, further increasing the difficulty of disassembly and assembly. This not only exacerbates the workload of maintenance personnel but also risks damaging components due to forced disassembly, increasing equipment maintenance costs. Therefore, there is an urgent need for a ladle covering device that allows for rapid disassembly and assembly. Utility Model Content

The hydraulic cylinders 42 are housed inside the heat insulation covers 41 and control the position of two moving wheels 43. One end of each hydraulic cylinder 42 passes through the mounting bracket 3 and is fixedly connected to a moving wheel 43. The moving wheels 43 abut against both sides of the guide rail 1 and can cooperate with the guide rail 1 to control the movement of the capping machine trolley 2. The second fixing component 5 includes a fixing platform 51 fixed to the end face of the mounting bracket 3. A motor 53 is connected to the top of the fixed platform 51 via a limiting mechanism 52. The limiting mechanism 52 can control the movement position of the motor 53. A screw 54 is fixedly connected between the output ends of the two motors 53 on opposite sides. An installation mechanism 55 is provided on the top of the guide rail 1. The limiting mechanism 52 includes a slide rod 521. Both ends of the slide rod 521 are fixedly connected to the fixed platform 51. A sliding sleeve 522 is slidably connected to the outer periphery of the slide rod 521. The sliding sleeve 522 is fixedly connected to the outer periphery of the motor 53. 1 and the sliding sleeve 522 can limit the sliding of the motor 53, so that it can move back and forth smoothly and prevent it from shaking and deviating during the movement; the mounting mechanism 55 includes a limiting block 551 that matches the limiting groove 552. The limiting block 551 is slidably connected in the limiting groove 552. The top of the limiting block 551 is fixedly connected to a fixing sleeve 553. The inner wall of the fixing sleeve 553 is provided with an internal thread that matches the screw 54. The screw 54 is threadedly connected in the fixing sleeve 553.

[0028] In one specific embodiment, in the quick-release ladle capping device of this utility model, both ends of the slide rod 521 are fixedly connected to fixing blocks. The bottom of the fixing blocks is fixedly connected to the top of the fixing platform 51. The fixing blocks can increase the stability of the slide rod 521 during installation and fixation, and prevent the slide rod 521 from shaking during use.

[0029] In one specific embodiment, in the quick-release ladle cover device of this utility model, the top of the mounting frame 3 is fixedly connected with multiple lifting lugs. This arrangement facilitates the lifting equipment to lift the mounting frame 3 and the cover-adding machine trolley 2, making it convenient to install or disassemble them.

[0030] In one specific embodiment, in the quick-release ladle cover device of this utility model, the fixed platform 51 has an L-shaped structure, and a triangular reinforcing rib plate is fixedly connected to its bottom. The triangular reinforcing rib plate can improve the stability of the fixed platform 51.

[0031] As one specific implementation, in the quick-release ladle cover device of this utility model, the top of the fixed platform 51 is provided with a slide rail, and a slider is slidably connected in the slide rail.

The positioning groove and the positioning block can prevent the limiting block 551 from dislodging from the inner cavity of the limiting groove 552.

[0033] The working principle of this invention's quick-release ladle cover device is as follows:

[0034] When the capping machine trolley 2 needs to be installed on the guide rail 1, the entire mechanism is first hoisted to a suitable position below the guide rail 1 using the lifting lugs. The hydraulic cylinder 42 is then extended, pushing the moving wheel 43 inward so that it contacts and locks onto both sides of the guide rail 1, initially positioning the capping machine trolley 2. Then, the motor 53 is started, and under the guidance and limit of the sliding rod 521 and the sliding sleeve 522, the motor 53 moves smoothly inward, driving the screw 54 through its output end to screw into the fixing sleeve 553 at the top of the guide rail 1. The screw 54 and the inner wall of the fixing sleeve 553 are screwed together to lock the mechanism. When the capping machine trolley 2 needs to be disassembled for maintenance, the motor 53 is operated in reverse to unscrew the screw 54 out of the fixing sleeve 553 to release the lock. Then, the hydraulic cylinder 42 is retracted, causing the moving wheel 43 to disengage from the guide rail 1. Finally, the entire capping machine trolley 2 can be lifted off the guide rail 1 using the lifting lugs to complete the disassembly.

[0035] In summary, compared with the prior art, the quick-release ladle capping device of this utility model has the following advantages and beneficial effects:

[0036] (1) This device has a simple structure and is easy to disassemble and assemble.

By setting the heat insulation cover 41, the hydraulic cylinder 42 is effectively protected from high temperature, ensuring its reliable operation.

[0037] (2) By setting the second fixing component 5, the device uses the motor 53 to drive the screw 54 to screw into or out of the internal thread of the fixing sleeve 553, so as to achieve a firm lock or quick release between the cover-adding machine trolley 2 and the guide rail 1. By setting the sliding rod 521 and the sliding sleeve 522, the motor 53 can be moved smoothly and the screw 54 can be prevented from being misaligned. The device as a whole can ensure stability under high temperature environment and can also achieve one-click quick disassembly and assembly, thus improving the maintenance efficiency of the equipment.
