Description

Movable gear-type ladle adding and removing device

technical field

The utility model relates to a ladle adding and removing cover device.

Background technique

At present, domestic steelworks, steelmaking foundries or other smelting enterprises mostly use open ladles without lids to carry molten steel or other smelting molten metals at high temperatures. Obviously, it takes a lot of energy to convert steel or other smelted and cast metals into liquid at high temperature. In addition, the distance between each process in the smelting area is relatively large, and the waiting time between each process is long. The high-temperature metal solution cools down rapidly during the production process. Only by relying on electricity or other media for continuous heating in each smelting process can it To meet the production needs of the overall smelting. The mouth of the ladle is open during the long-term transportation, and the molten steel is in direct contact with the air. Due to the temperature difference between the molten steel and the air, heat convection occurs continuously between the two, and the molten steel loses a lot of heat; at the same time, the molten steel ladle emits a large amount of smoke and dust, which pollutes the environment and reduces the service life of the equipment.

Contents of the invention

The purpose of this utility model is to provide a kind of structure is reasonable, realizes safe, reliable, smooth and quick ladle cover adding and removing device of the moveable pinch-type ladle.

The technical solution of the utility model is:

A movable pinion type steel ladle adding and removing device is characterized in that it includes a steel structure support located on the ladle moving channel, a movable frame is arranged on the upper part of the steel structure support, and the left and right ends of the mobile frame are respectively connected to the upper part of the steel structure support. The left and right rails of the three pins are fixed on the mobile frame, and the three pins are respectively matched with the three jacks on the ladle cover. The upper surfaces of the three pins are slope surfaces, and the middle one A horizontal plane is arranged behind the slope surface of the teeth; a lid hook is arranged on the ladle cover, and the lid hook cooperates with the hinge on the steel ladle.

The mobile frame is connected with power components (hydraulic cylinder, electro-hydraulic push rod, winch, electric cylinder, etc.). The length direction of the movable frame is perpendicular to the length direction of the left and right rails.

The utility model has a reasonable structure and can meet the requirement of a short track distance in the workshop. The cover adding device is vertically installed with the track, and the ladle cover can be added safely, reliably, smoothly and quickly through the movement of the gear-shaping mechanism. The movable gear-type ladle adding and removing device is mainly used to keep the ladle in the covered state during the entire steelmaking-continuous casting process except for converter tapping and refining, and does not increase the workload and labor of driving. The ton of steel can be Saving 20-30 yuan in production costs, greatly reducing steelmaking production costs, and significantly improving the environmental quality of steelmaking areas is a project that must be introduced in domestic steel mills for energy conservation and environmental protection, and has broad market needs and development prospects.

The utility model also has the advantages of reducing energy consumption, reducing heat dissipation, and saving costs. Cancel the online baking ladle and cancel the covering agent. Make the temperature of molten steel in the ladle more uniform, and increase the service life of the refractory material of the ladle. There is no need to occupy the production vehicle in the workshop during the capping and capping operations. The operation is stable, safe and reliable. Compared with similar products, it can be installed and operated in workshops with short track distances. It is suitable for the working condition where the ladle car track of the converter station is perpendicular to the ladle car track of the LF furnace.

detailed description

A movable pinion-type ladle adding and removing device, including a steel structure support 1 located on the ladle moving channel, a movable frame 2 is arranged on the upper part of the steel structure support, and the left and right ends of the movable frame are respectively connected to the left and right sides of the upper part of the steel structure support. , right track 3, 4 cooperate, three pins 5 are fixedly mounted on the movable frame, and three pins respectively cooperate with three sockets on the ladle cover 6, and the upper surfaces of the three pins are slope surfaces, A horizontal plane is set behind the slope surface of a slotting tooth in the middle; a lid hook 7 is set on the ladle cover, and the lid hook cooperates with the hinge 8 on the steel ladle.

The mobile frame is connected with power components (hydraulic cylinder, electro-hydraulic push rod, winch, electric cylinder, etc.) 9 . The length direction of the movable frame is perpendicular to the length direction of the left and right rails. Also have ladle 9 among the figure.

The process of adding and removing the cap is mainly through the telescopic movement of the shaping gear with the help of power components (hydraulic cylinder, electro-hydraulic push rod, hoist, electric cylinder, etc.) to complete the action of adding and removing the cap. quasi-position.

1. Prepare to remove the cover

The empty ladle with cover is hoisted to the ladle car, advances to the designated position and then stops. After the ladle stops at the correct position, the gears are driven to the end of the ladle through the contraction of the power element, and the cover is ready to be removed.

2. Remove the cover

When the three gears on the gear shaping mechanism are in contact with the three pins forming the jacks on the ladle cover, the power components act, the gears continue to move forward, and the ladle cover also moves upwards along with the slope of the gears. Until it stops on the middle pinion plane, the action of removing the cover is completed.

3. Remove the cover and complete

After the pinion takes off the ladle cover, the pinion takes the ladle cover and continues to drive forward for a certain distance and then stops. The ladle moves along the track to the converter or refining furnace station to receive molten steel.

4. Stamped

After receiving the molten steel, the ladle returns to the limited position. The gear is extended by the power element and moves backward. When the cover hook collides with the upper hinge of the ladle, as the gear continues to extend, the ladle cover slowly slides down along the slope of the gear and covers the ladle, which is automatically completed Capping action.

5. Lifting

After the capping is completed, the steel ladle continues to drive to the lifting station, and the covered steel ladle is hoisted by the workshop to enter the next process.
