Description

Technical Field

[0001] The present invention relates to the field of workshop conveyors, and in particular to a multifunctional rotary rail trolley and a method for using the same. Background Art

[0002] The rotating rail trolley used to rotate liquid metal ladles is an important transfer tool in the smelting field and plays an important role in the smelting process. In particular, with the high-quality, high-efficiency and high-profit development of the steel industry, it is necessary to optimize, upgrade and make breakthroughs in the process equipment and layout of the current smelting field. The "multi-functional rotating rail trolley" is an important transfer and process carrying tool that can realize multiple walking directions (rotation angles) and efficient integration of multiple smelting stations for vehicles such as steel ladles and iron ladles. Its key role in the current smelting process is particularly prominent.

[0003] However, the current rotating rail trolley only has the simple function of rotating the ladle vehicle, which cannot meet the high-quality development requirements of the metallurgical industry for "extreme efficiency, low carbon and green" process innovation and equipment upgrading; and because the smelting function of the liquid metal ladle as an important refining and processing container is also constantly improving, liquid metal leakage accidents may occur due to reasons such as lining resistant material corrosion, bottom blowing air bricks, and sliding water nozzles. When a high-temperature liquid metal leakage accident occurs in the liquid metal ladle rotated by the rotating rail trolley, if the accident liquid metal cannot be promptly, effectively and continuously diverted to a safe position, the high-temperature liquid metal will quickly burn the relevant workstations and transportation equipment; and it will cause fires and explosions, and in severe cases may lead to major accidents such as production stoppages or casualties. Summary of the Invention

[0004] In order to overcome the defects of the prior art and provide a smelting and conveying equipment with strong adaptability, safety and reliability, the present invention discloses a multifunctional rotary rail trolley and a method for using the same.

The multifunctional rotating rail trolley is characterized in that it further comprises a ring rail, an entry channel, a transition rail, a rotating rail trolley, a wheel set, a positioning locking pin, a guide outlet, a guide drum, a container bag car, a container bag seat, a reel and a container bag. The circular track is located at the intersection of the first set of straight tracks and the inclined track. An access channel is provided at the center of the circular track for laying various cables, argon pipes, nitrogen pipes and other pipelines. The rotating rail trolley is movably arranged on the ring rail through the wheel set at the bottom so that it can move in a circle along the ring rail around the center of the ring rail. The rotating rail trolley is provided with a positioning locking pin for positioning the rotating rail trolley at different rotation angles. A guide port is provided on one side of the rotating rail trolley. The cable, argon pipe and nitrogen pipe connected to the rotating rail trolley are passed through the guide port. The guide port is used for conveying and controlling various media required for smelting the liquid metal bag on the liquid metal bag car at the smelting station, so that the liquid metal bag car can realize multiple directions of forward or backward operation and smelting operations in different directions before and after the rotation angle of the rotating rail trolley. The top surface of the rotating rail trolley is provided with a transition rail; A container bag car is movably provided on the first set of straight rails and the second set of straight rails. A container bag seat is provided on the container bag car. A reel is provided on one side of the container bag seat for passing various cables, bottom blowing argon pipes, nitrogen pipes and other pipelines connected to the container bag seat. The container bag is placed in the container bag seat.

The guide cylinder receives the accident liquid metal flowing out from the side flow channel of the container package car and drains it to a safe position. The guide cylinder is used to solve the problem of liquid metal leakage in the liquid metal package carried by the liquid metal package car after it is driven onto the rotating rail trolley. The liquid metal can be smoothly drained out, thereby ensuring that the accident liquid metal leaked from the liquid metal package car when it is parked on the rotating rail trolley and during the entire rotation process can be reliably drained to a safe position.

[0007] The method for using the multifunctional rotating rail trolley is characterized by being implemented in the following steps in sequence: S1. Set up machine positions: Set up an area on the first set of straight tracks as a rotating standby area, an area on the second set of straight tracks as a straight standby area, and a smelting standby area at the intersection of the inclined tracks and the second set of straight tracks. The container car on the first set of straight tracks is designated as container car 1, and the container car on the second set of straight tracks is designated as container car 2. S2. Fixed parking space: 1# container package car carrying a container package containing liquid metal stops at the rotating standby position, and the cables, argon pipes and nitrogen pipes for the container package are all passed through the entrance channel below the circular rail, and then sequentially pass through the guide port of the rotating rail trolley and the reel of the container package seat and are respectively connected to the cable interface, argon interface and nitrogen interface on the container package seat; the cables and hydraulic pipes for the rotating rail trolley (2) are sequentially passed through the central channel below the circular rail (14) and are respectively connected to the drive motor interface of the rotating wheel group and the hydraulic interface of the positioning locking pin. 2# container package car also carries a container package containing liquid metal and stops at the straight standby position; S3.

Release the positioning locking pins, then rotate the rotating rail trolley along the circular track until the transition rail and the inclined rail are aligned, then secure with the positioning locking pins. Drive the No. 1 container car along the transition rails onto the inclined rails and advance to the smelting standby station. S4. Smelting: The liquid metal in the container bag of the first chartered car is smelted at the smelting standby position. After smelting of the first chartered car is completed, the second chartered car is moved from the straight standby position along the second set of straight tracks to the smelting standby position to smelt the liquid metal in the container bag of the second chartered car. After smelting of the second chartered car is completed, the second chartered car is returned along the second set of straight tracks to the straight standby position and the container bag is hoisted and transported to another process point. S5. Return: Container car #1 is driven along the inclined track onto the transition rail on the rotating rail trolley. The positioning locking pin is then released, and the rotating rail trolley is rotated along the circular track until the transition rail and the first set of straight rails are aligned. The positioning locking pin is then used to secure the trolley. Container car #1 is returned along the first set of straight rails to the rotation standby position and the container package is hoisted to another process point. Container car #1 receives the container package containing liquid metal again, and then returns to step S2 and repeats the process.
