Description
Technical field
The utility model relates to production facilities field, is specially a kind of self-balance sling.
Background technology
While changing roller on manufacturing line, the cranes that adopt are sling roller more, but often roller top has other equipment to exist, therefore there is the problem that crane cannot be close, now can only adopt manually just roller to sling, so exist certain potential safety hazard and operating efficiency low.
Summary of the invention
The purpose of this utility model is, a kind of suspender is provided, and it can sling roller in the situation that operation is height-limited, and can avoid, because of lifting roller, the unbalance situation of center of gravity occurs.
In order to achieve the above object, the utility model is achieved in that
A kind of self-balance sling, it comprises lifting appliance, the suspension hook being connected with lifting appliance, the lifting rope being connected with suspension hook, it is characterized in that: also comprise arm, extension arm, suspension clamp, motor, screw mandrel, inner screw sheath and master cock; Arm and lifting rope hang and connect, and the two ends of arm are respectively equipped with suspension hook and inner screw sheath, and extension arm top is provided with screw mandrel, and screw mandrel is threaded with inner screw sheath, thereby extension arm is positioned at arm below; Motor is located at extension arm end, and the rotating shaft of motor is connected with screw mandrel, and the rotation of motor drives screw mandrel turn and drive extension arm to realize expanding-contracting action; Master cock is electrically connected with motor, and controls the action of motor.
Described self-balance sling, described suspension clamp comprises two annular arms and a hanger, and two annular arms lay respectively at hanger both sides and surround an annular, between three, connect by a bolt, and the inner side of annular arm is provided with cushion block.
Described self-balance sling, also comprises clump weight, and described clump weight is located on extension arm.
The utility model adopts above-mentioned design, and it is in when lifting, and extension rod stretches out by calculated length in advance, utilizes arm of force principle of moments to reach the balance of suspender, so, can height-limited in the situation that, use lifting appliance that roller is sling, and facilitates the upkeep operation of roller.
