ANCHOR CASTING AND WEIGHING DEVICE

摘要

This anchor casting and weighing device (1) includes: a chain wheel (21), around which an anchor chain (3) is wound; a brake mechanism (30) which brakes the rotation of the chain wheel; a rotational speed measurement means (22) which measures the actual rotational speed of the chain wheel; a setting means (100) which sets the target anchor casting speed of the chain wheel; a braking force adjustment mechanism (30) which includes a hydraulic actuator for driving the brake mechanism and adjusting the braking force of the brake mechanism according to the pressure of pressurized oil supplied to the hydraulic actuator; and a control means (100) which, in order that the actual rotational speed of the chain wheel measured by the rotational speed measurement means follows the target anchor casting speed set by the setting means, outputs a command voltage to the braking force adjustment mechanism so as to control the pressure of the pressurized oil supplied to the hydraulic actuator.
