[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Example 1: Reference Figure 1-4A quick replacement device for a ladle shroud comprises a rod body 1, a pull head 2 is mounted on the rod body 1, a pull sleeve 3 is threadedly sleeved on the outer wall of the rod body 1, a bracket 4 is arranged at one end of the rod body 1, a moving seat 5 is slidably mounted on the bracket 4, a sleeve 6 is mounted on the moving seat 5, an adjusting rod 7 is sleeved in the sleeve 6, a fixing sleeve 8 is mounted on the adjusting rod 7, a first fixing ring 9 and a second fixing ring 10 are movably mounted in the fixing sleeve 8, a first fixing screw 11 and a second fixing screw 12 are threadedly mounted on the fixing sleeve 8, and the second fixing ring 10 and the first fixing ring 9 are respectively sleeved on the first fixing screw 11 and the second fixing screw 12. The outer wall of the fixed screw 11 and the second fixed screw 12, the outer wall of the sleeve 6 is installed with a connecting plate 24, the bracket 4 is installed with a hydraulic cylinder 14, and the other end of the hydraulic cylinder 14 is installed on the connecting plate 24. When in use, first open the slide plate of the ladle, open the sliding water outlet of the ladle, and move the replacement device to the side of the ladle. First, slide the adjusting rod 7 in the sleeve 6 to adjust the height of the fixed sleeve 8, and align the fixed sleeve 8 with the sliding water outlet of the ladle. After adjusting the height of the fixed sleeve 8, the fixing bolt 17 can be screwed into the sleeve 6, and the fixing bolt 17 will abut against the outer wall of the adjusting rod 7 The adjusting rod 7 is fixed and the height of the fixing sleeve 8 is locked. Then the rod body 1 is passed through the fixing sleeve 8 and inserted into the sliding nozzle of the ladle, and the old long nozzle of the ladle is hooked through the pull head 2. The knob 13 is turned. The rotation of the knob 13 will drive the first fixing screw 11 and the second fixing screw 12 to rotate. The rotation of the first fixing screw 11 and the second fixing screw 12 will drive the first fixing ring 9 and the second fixing ring 10 to clamp and fix the rod body 1, and make one end of the first fixing ring 9 and the second fixing ring 10 against the pull sleeve 3. At this time, the first fixing ring 9 and the second fixing ring 10 are One end of the fixing ring 10 is against the pulling sleeve 3. When the rod body 1 is pulled outward, the pulling sleeve 3 can become a force point to prevent the first fixing ring 9 and the second fixing ring 10 from sliding on the outer wall of the rod body 1 during pulling. The sleeve 6 can be pulled toward the outside of the ladle sliding nozzle by the hydraulic cylinder 14, thereby driving the first fixing ring 9 and the second fixing ring 10 to pull the rod body 1 toward the outside of the ladle sliding nozzle. At this time, the old ladle long nozzle can be pulled out of the ladle sliding nozzle through the rod body 1, and then the new ladle long nozzle can be replaced. The operation is relatively convenient and the ladle long nozzle can be quickly replaced.
[0022] Example 2: Reference Figure 3 , Figure 4A knob 13 is installed at one end of the first fixing screw 11 outside the fixing sleeve 8, and a plurality of ring-shaped shifting blocks are installed on the knob 13. The inner walls of the first fixing ring 9 and the second fixing ring 10 are both installed with contact pads 16. A support rod 15 is installed in the fixing sleeve 8. The first fixing ring 9 and the second fixing ring 10 are both slidably installed on the support rod 15. A threaded groove 18 is provided on the sleeve 6. A fixing bolt 17 is rotatably installed in the threaded groove 18. The knob 13 can be driven to rotate by shifting the shifting block. The rotation of the knob 13 drives the first fixing screw 11 to rotate. The rotation of the first fixing screw 11 drives the second fixing screw 12 to rotate. Through the limiting effect of the support rod 15, the rotation of the first fixing screw 11 and the second fixing screw 12 will drive the second fixing screw 12 to rotate. The fixed ring 10 and the first fixed ring 9 are respectively close to each other on the outer walls of the first fixed screw 11 and the second fixed screw 12 and clamp the outer wall of the rod body 1. At this time, one end of the first fixed ring 9 and the second fixed ring 10 are against the pulling sleeve 3. When the rod body 1 is pulled outward, the pulling sleeve 3 can become a force point to prevent the first fixed ring 9 and the second fixed ring 10 from sliding on the outer wall of the rod body 1 during pulling. By setting the contact pad 16, the deformation of the rod body 1 caused by clamping can be reduced. After adjusting the height of the fixing sleeve 8, the fixing bolt 17 can be screwed into the sleeve 6. The fixing bolt 17 will be against the outer wall of the adjusting rod 7, thereby fixing the adjusting rod 7 and locking the height of the fixing sleeve 8, which is convenient for inserting the rod body 1 into the sliding water outlet of the ladle.
[0023] Reference Figure 3 In order to increase the stability during pulling, a slider 19 is installed at the bottom of the sleeve 6, and a slide groove 20 is opened on the bracket 4. The slider 19 is slidably installed in the slide groove 20. When the hydraulic cylinder 14 pulls the connecting plate 24, the slider 19 will be driven to slide in the slide groove 20. Through the setting of the threaded groove 18 and the slider 19, on the one hand, the sleeve 6 and the mechanism on the sleeve 6 can be supported to increase the stability during sliding.
[0024] Reference Figure 2 , 3 In order not to affect the movement of the rod body 1 and to facilitate the movement of the device, a plurality of moving wheels 21 are installed at the bottom of the rod body 1, and a through opening 22 is opened on the bracket 4. When the rod body 1 is pulled outward, the rod body 1 will pass through the through opening 22, and the bracket 4 will not hinder the movement of the rod body 1. The user can push the push handle 23 and drive the device to move through the plurality of moving wheels 21.
[0025] Reference Figure 2 In order to improve the comfort of the operator in pushing the push handle 23, the push handle 23 is installed on the bracket 4, and a soft pad is installed in the push handle 23. When the user pushes the push handle 23, the user can hold the soft pad with his hand to improve the comfort of contact.
[0026] The working principle of the utility model is as follows: when in use, first open the slide plate of the ladle, open the sliding nozzle of the ladle, and move the replacement device to the side of the ladle. First, slide the adjusting rod 7 in the sleeve 6 to adjust the height of the fixing sleeve 8 and align the fixing sleeve 8 with the sliding nozzle of the ladle. After adjusting the height of the fixing sleeve 8, screw the fixing bolt 17 into the sleeve 6, and the fixing bolt 17 will abut against the outer wall of the adjusting rod 7, thereby fixing the adjusting rod 7 and locking the height of the fixing sleeve 8. Then pass the rod body 1 through the fixing sleeve 8 and insert it into the sliding nozzle of the ladle, and hook the old long nozzle of the ladle through the pull head 2, and turn the knob 13. The rotation of the knob 13 will drive the first fixing screw 11 and the second fixing screw 12 to rotate. The first fixing screw 11 and the second fixing screw 12 The rotation will drive the first fixing ring 9 and the second fixing ring 10 to clamp and fix the rod body 1, and make one end of the first fixing ring 9 and the second fixing ring 10 rest on the pulling sleeve 3. At this time, one end of the first fixing ring 9 and the second fixing ring 10 is against the pulling sleeve 3. When the rod body 1 is pulled outward, the pulling sleeve 3 can become a force point to prevent the first fixing ring 9 and the second fixing ring 10 from sliding on the outer wall of the rod body 1 during pulling. The sleeve 6 can be pulled toward the outside of the ladle sliding nozzle by the hydraulic cylinder 14, thereby driving the first fixing ring 9 and the second fixing ring 10 to pull the rod body 1 toward the outside of the ladle sliding nozzle. At this time, the old ladle long nozzle can be pulled out of the ladle sliding nozzle through the rod body 1, and then the new ladle long nozzle can be replaced. The operation is relatively convenient and the ladle long nozzle can be quickly replaced.
