Jib type crane container spreader stabilizer

Abstract

The invention discloses a container hoister stabilizer for a jib type crane. A balance weight slides up and down in a balance weight supporting frame and is connected with a container hoister through a left pulling steel wire rope and a right pulling steel wire rope. One end of the left pulling steel wire rope and one end of the right pulling steel wire rope are connected to the two corners of the long edges of the container hoister correspondingly, and the other end of the left pulling steel wire rope and the other end of the right pulling steel wire rope are wound on a middle jib pulley, a balance weight supporting frame pulley set and a balance weight pulley set and fixed to the balance weight supporting frame correspondingly. A motor is connected with a winding drum through an electromagnetic clutch. The winding drum is fixed to a crane rotation platform. A driving steel wire rope with an input end and an output end is wound on the winding drum, that is, when the winding drum rotates, one end of the driving steel wire rope is wound into the winding drum, and the other end of the driving steel wire rope is wound out of the winding drum. The two ends of the driving steel wire rope are wound on an upper guide pulley and a lower guide pulley and connected to the upper portion and the lower portion of the balance weight correspondingly. Rotation and swing of containers can be reduced, the containers can be stabilized, the operation efficiency of the crane is improved, and the safety is good.

Description

technical field [0001] The invention relates to a jib type crane spreader, in particular to a jib type crane container spreader stabilizer. Background technique [0002] General jib cranes, such as portal cranes, tire cranes, etc., often use simple container spreaders to lift containers, and the spreaders are suspended on the hooks through four wire ropes. During operation, manually align the twist locks of the spreader with the four corner fitting holes on the top of the container. Due to single-point lifting, during the container hoisting process, the container will rotate and swing due to the slewing and luffing motion of the crane boom. If only the self-damping of the simple container spreader wire rope system is used to consume the rotation and swing energy of the container, it will take a long time and directly affect the operating efficiency of the crane; if the container is manually righted, there will be hidden dangers to the personal safety of the workers. The ef...
