POWER SUPPLY APPARATUS OF STEEL PLATE COIL LIFTER FOR CRANE

摘要

The present invention is a power supply device for a steel sheet coil lifter for cranes, more specifically, a lifter used to move and stack steel sheet coils to a motor for generating a driving force to operate the forceps provided in the lifter. The present invention relates to a power supply device for a steel plate coil lifter for cranes, which is capable of smoothly supplying power, and the present invention is connected to a swiveling shaft rotatably to a supporting member having a ring, and geared motor at a proper position of the swiveling shaft. In the conventional steel plate coil lifter is mounted to the rotating swiveling gear is coupled to the lower end of the swiveling shaft, the drive force of the motor is transmitted through a plurality of links to clamp the coil clamping the coil, the support It is installed on one side of the member and extends from the crane to power the coil lifter. A control box to which a cable lead wire is connected to supply a terminal box, a terminal box having a plurality of supply terminals installed on a bottom surface of the control box and protruding downward from the cable lead wire in order to draw out the power supply; It is formed in a circumferential shape with respect to the center of rotation so as to maintain the state of energization even when it is rotated. It is surrounded by insulating material so that it can be energized only by artificial contact. And a terminal box having a grounding ring provided therein, and an inlet terminal installed on a bottom surface of the grounding ring and connected to an induction groove so as to be energized in correspondence with an upper supply terminal to supply power to a motor driving a tong leg. It is provided in the terminal box to increase the adhesion between the supply terminal and the lead A doengeot hayeoseo an elastic spring installed elasticity to the charge action.
