Description

Technical Field

[0001] This application relates to the field of steelmaking auxiliary equipment technology, and more specifically, to a tilting mechanism for a long trunnion boom type ladle. Background Technology

[0002] The ladle is a key piece of equipment in the steelmaking process. After continuous casting is completed, the molten slag and residual steel in the ladle are first emptied by a metallurgical crane, and then the ladle is lifted by the crane to the hot repair station for hot repair work, such as cleaning the residual steel in the ladle sliding nozzle orifice and on the bottom blown aeration bricks, and replacing the ladle sliding nozzle slide plate. Because the above process steps either occupy the crane continuously or involve repeated lifting, the operation cycle is extended, which directly affects the production rhythm of steelmaking. Summary of the Invention

[0003] The purpose of this application is to provide a tilting mechanism for a long trunnion boom type ladle, reducing reliance on cranes and shortening the hot repair operation cycle.

A pin is provided on the support frame, the hanger is mounted on the pin, and the toggle mechanism includes a drive assembly and a lever, the drive assembly driving the lever to rotate.

[0006] Preferably, the drive assembly includes a motor, a rotating shaft, a drive gear, and a driven gear. The motor is mounted on the support frame and drives the rotating shaft to rotate.

[0028] Example

[0029] like Figure 1-3 As shown in the embodiment of this application, the tilting mechanism for a long trunnion boom type ladle includes a fixed frame 1, a hanger 2, a support frame 3, and a toggle mechanism 4. A pin 5 is provided on the support frame 3, and the hanger 2 is mounted on the pin 5. The toggle mechanism 4 includes a drive assembly 6 and a lever 7. The drive assembly 6 drives the lever 7 to rotate. Since the hanger 2 is in a suspended state, it will not be disturbed by the hanger 2 when the drive assembly 6 drives the lever 7 to rotate.

[0030] After continuous casting is completed, the ladle 21 is transferred by a crane. The fixed frame 1 and the hanger 2 jointly support the ladle 21. Under the action of the drive component 6, the lever 7 moves the ladle 21 to rotate. After the ladle 21 rotates to the set angle, it is easy to pour out the slag in the ladle 21 and perform hot repair on the ladle 21, thereby reducing the dependence on the crane and shortening the hot repair operation cycle.

[0031] In this embodiment, the drive assembly 6 includes a motor 8, a rotating shaft 9, a drive gear 10, and a driven gear 11. The motor 8 is mounted on the support frame 3 and drives the rotating shaft 9 to rotate. The drive gear 10 is mounted on the rotating shaft 9. The driven gear 11 is rotatably mounted on the pin 5 and is located between the hanger 2 and the support frame 3. The hanger 2 and the support frame 3 respectively limit the driven gear 11. The driven gear 11 meshes with the drive gear 10. The lever 7 is mounted on the driven gear 11.

[0032] In use, the motor 8 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the driving gear 10 to rotate, causing the driven gear 11 to rotate on the pin 5, the driven gear 11 drives the lever 7 to rotate, and the lever 7 causes the steel ladle 21 to rotate.

[0033] In this embodiment, a locking mechanism 12 is provided on the support frame 3. The locking mechanism 12 is used to lock the driven gear 11. The setting of the locking mechanism 12 can improve the overall stability.

[0034] In this embodiment, the driven gear 11 is provided with at least one positioning hole 13. The locking mechanism 12 includes a hydraulic cylinder 14 and a plug 15. The hydraulic cylinder 14 is provided on the support frame 3. The hydraulic cylinder 14 drives the plug 15 to enter or leave the positioning hole 13. After the ladle 21 is rotated to a set angle, the hydraulic cylinder 14 drives the plug 15 to enter the positioning hole 13, and the driven gear 11 is locked to rotate. After the hydraulic cylinder 14 drives the plug 15 to leave the positioning hole 13, the drive assembly 6 can drive the lever 7 to rotate.

[0035] In this embodiment, the locking mechanism 12 further includes a guide seat 16, which is disposed on the support frame 3. The plug 15 is movably inserted through the guide seat 16, and the guide seat 16 plays a limiting and guiding role for the plug 15 to ensure the stability of the plug 15 in use.

[0036] In this embodiment, in order to improve the stability of the rotating shaft 9, the rotating shaft 9 is mounted on the support frame 3.

[0037] In this embodiment, in order to reduce the resistance encountered when the rotating shaft 9 rotates, a first bearing 17 is provided between the rotating shaft 9 and the support frame 3.

[0038] In this embodiment, in order to reduce the output speed of the motor 8 and at the same time amplify the output torque according to the reduction ratio, a planetary reducer 18 is provided between the motor 8 and the rotating shaft 9.

[0039] In this embodiment, in order to facilitate quick stopping of movement and improve the positioning accuracy of the ladle 21, a brake 19 is provided between the motor 8 and the rotating shaft 9.

[0040] In this embodiment, in order to reduce the resistance encountered when the driven gear 11 rotates, a second bearing 20 is provided between the driven gear 11 and the pin 5.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
