Rotary adjusting mechanism for mounting planetary carrier of planetary reducer

The utility model relates to the technical field of coal mine machinery, in particular to a rotary adjusting mechanism for mounting a planetary carrier of a planetary reducer. The rotary adjusting mechanism comprises a circular connecting plate, wherein a first lifting eye is fixed in the center of the upper surface of the connecting plate; three first lifting hooks are uniformly arranged on the circumference of the lower surface of the connecting plate by taking the first lifting eye as the circle center; a second lifting eye is suspended on each first lifting hook; the lower ends of the second lifting eyes are connected onto connecting nuts; the lower ends of the connecting nuts are in threaded connection with second lifting hooks. The rotary adjusting mechanism is simple in structure, ingenious in design, and good in replaceability, and can be used for mounting planetary carriers of various planetary reducers; in addition, the height at which a planetary carrier is hoisted can be effectively adjusted; the planetary carrier can be quickly mounted in a housing conveniently through a hoisting mechanism.
