Described through hole can be bar shaped, the diameter of described nut is greater than the width of described through hole and the diameter of described screw rod is no more than the width of described through hole, described screw rod can move or rotate in described through hole, so the lower surface driving claw to play flap seat in annular near or play the direction horizontal slip in the flap seat center of circle away from annular or be that axle horizontally rotates with screw rod.
During lifting bearing, bearing inner ring or outer ring are placed in annular and play flap seat inside, annular is made to play flap seat around bearing inner ring or outer ring, each claw is by playing the direction horizontal slip in the flap seat center of circle or being axle horizontal rotary with screw rod then stretching into annular to play flap seat inside and the bottom being supported on bearing inner ring or outer ring to close annular, bearing inner ring or outer ring can be played flap seat with annular and be sling; During unloading bearing, each claw is by playing the direction horizontal slip in the flap seat center of circle away from annular or taking screw rod as axle horizontal rotary then disengaging bearing.
Described through hole also can be circular, the diameter of described nut is greater than the diameter of described through hole and the diameter of described screw rod is no more than the diameter of described through hole, described screw rod can rotate in described through hole, and then the lower surface driving claw to play flap seat in annular is that axle horizontally rotates with screw rod.
During lifting bearing, bearing inner ring or outer ring are placed in annular and play flap seat inside, annular is made to play flap seat around bearing inner ring or outer ring, each claw plays flap seat inside and the bottom being supported on bearing inner ring or outer ring by being axle horizontal rotary with screw rod then stretching into annular, and bearing inner ring or outer ring can be played flap seat with annular and be sling; During unloading bearing, each claw is by taking screw rod as axle horizontal rotary then departing from bearing.
Described annular plays flap seat can make different sizes according to by the diameter of lifting bearing inner ring or outer ring, and under normal circumstances, the diameter that annular plays flap seat should be not less than 1m.The material that described annular plays flap seat and claw should have certain hardness and intensity, to meet normal lifting and the unloading of bearing.Usually, described annular plays flap seat and claw is steel material, such as, adopt Q195, Q235,20, No. 45 carbon steel or Q345 alloy steel etc.
During lifting bearing, be connected with hanger by each described lifting eye, hanger connects adjustable chain sling.When the bottom of bearing inner ring or outer ring to be supported by described claw and in company with annular flap seat sling together time, bearing inner ring or outer ring are adjusted to level by the degree of depth that length or hanger by adjusting adjustable chain sling screw in lifting eye, again bearing inner ring or outer ring are winched to directly over installation site, fall annular play flap seat and make claw depart from bearing, thus bearing inner ring or outer ring are placed into correct installation site.
The large size bearing lifting tool that the utility model provides plays flap seat and claw cooperation by annular, and handling and the installation that can complete large size bearing safely, are easily placed, and avoids difficulty and the dangerous problem of free-hand carrying existence; In addition, at installation shaft brought forward, first under state sling by bearing, by the degree of depth of hanger screw-in on the described lifting eye of adjustment or the length of adjustable chain sling, bearing inner ring or outer ring can be adjusted to level, winch to again directly over installation site and place, ensure that the installation in tram of bearing inner ring or outer ring thus.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model large size bearing lifting tool;
Fig. 2 is the local structure enlarged drawing of the lifting tool of large size bearing shown in Fig. 1;
