Abstract

The invention discloses a judging device and a judging method for a revolution overlapping area of a pile-surrounding-type revolution crane, belonging to the field of cranes. The judging device comprises a detection module and a logic module; the detection module is used for detecting different working states of a revolving platform and emitting signals; and the logic module is used for judging the working states of the revolving platform according to the signals detected by the detection module. According to the judging device and the judging method, by detecting the working states of the revolving platform, the working states of the revolving platform are accurately acquired; the condition that the revolving platform exceeds a revolving range during a revolving process is avoided, and thus damage to cable drag chains is prevented; and normal work of the pile-surrounding-type revolution crane is ensured.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a judging device and judging method for the slewing overlapping area of ​​a pile-wrapping slewing crane. Background technique [0002] Pile-encircling slewing cranes are usually installed on the legs of offshore platforms, and are widely used because of their small platform space, compact structure, large lifting capacity, and long lifting radius. The pile-wound slewing crane mainly includes a base column, a slewing platform and a lifting mechanism. The slewing platform is rotatably set on the base column, and the lifting mechanism is set on the slewing platform. There is enough space in the middle of the base column and the middle of the slewing platform. Allow the legs to pass through. [0003] For general full-slewing cranes, a slip ring box is usually installed in the middle of the crane to ensure its full 360-degree rotation. For the slewing crane around the pile, because ...
