TECHNICAL FIELD

[0001] The utility model relates to the technical field of the dismounting and mounting of a conical roller of a ring roller, in particular to a dismounting and mounting tool for the conical roller of a ring roller. BACKGROUND

[0002] The conical roller of a large ring roller is of an irregular shape, has a total length of 3877mm, a maximum diameter of Φ1280mm, and weighs 15 tons, and is installed on the ring roller at an angle of 32°. The conical roller is difficult to dismount and mount, and if the angle is not adjusted properly during the dismounting and mounting process, the inner wall of the machine body is easily damaged or the conical roller cannot be dismounted, which is not only extremely low in efficiency, but also has serious safety hazards during the dismounting process, and the entire dismounting and mounting process takes about 10 hours.

[0003] The conventional dismounting method is to loosen the locking bolts of the conical roller and the machine body, and gradually push the conical roller out of the position of 120-150mm using a jack. A 20T round sling is hung on the jacks at the position of 120-150mm, and the sling is in a tight state to prevent the conical roller from sliding down due to the 32° angle and the self-weight. After the conical roller is gradually pushed out of the position of 320-350mm, the sling is moved to the groove part of the conical roller outer sleeve, and the hoisting sling is tightened in a tight state. The conical roller is dismounted from the parent body by moving the conical roller frame, and the conical roller is hoisted out of the parent body for storage by using a crane.

[0004] The conventional mounting method is to move the sling to the groove part of the conical roller outer sleeve by using a crane, to find the correct radial balance angle and adjust the axial angle to 32° by using a 5T hand-operated hoist. The crane is moved to center, the conical roller is installed into the position of 30-50mm by moving the crane, and then a mandrel is used to push against the conical roller to slowly and cooperatively install it, and the gap between the conical roller and the parent body is kept during the installation process to avoid damaging the machine body. When the conical roller is installed into the position of 150-200mm, the mandrel is used to push against the conical roller to prevent it from sliding down, the sling is loosened and moved to the root of the conical roller, the conical roller is slowly hoisted again for reinstallation, and the conical roller is finally installed and locked by using the fixing bolts.
