Description

Technical Field

[0001] The utility model relates to the technical field of single-beam balance wheels, and particularly relates to a single-beam balance wheel. Background Technique

[0002] The hoisting mechanism is an essential basic component of any crane to enable the lifting and lowering movement of goods. The quality of the hoisting mechanism will directly affect the working performance of the entire crane. The hoisting mechanism mainly includes a driving device, a drum, a lifting appliance, a balance pulley, and a braking device. The steel wire rope is wound around the drum, passes through the lifting appliance and the balance pulley, and then winds back to the drum along the original path. During operation, the driving device drives the drum to rotate in different directions, driving the lifting appliance to rise or fall, thereby driving the materials on the lifting appliance to move up and down.

[0003] Currently, the single-beam balance wheel in the prior art usually has a balance pulley arranged in a movable pulley block. Two steel wire ropes are respectively wound around the movable pulley block and the fixed pulley block and then are hinged to both ends of the base through a connecting sleeve. This structure can ensure that after one steel wire rope breaks, the other can also better support the load under the hook. During use, since the balance pulley in the prior art is directly fixed on the trolley frame and the angle of the pulley cannot be adjusted, during the process of lifting materials, the tension of the steel wire rope changes at all times with the different positions of the materials, resulting in a large friction force between the steel wire rope and the groove of the balance pulley. After long-term friction, the service life of the steel wire rope is relatively short, and there is a problem of a large friction force between the steel wire rope and the groove of the balance pulley. And during lubrication, which is one of the important daily maintenance tasks, the quality of the lubrication of the pulley not only directly affects the normal operation and service life of the pulley, but the existing lubrication method is mainly manual smearing, resulting in a large labor intensity and low efficiency of workers, and there is a problem of inconvenient lubrication of the pulley.
