Abstract

The invention relates to the field of marine ship crane debugging, in particular to a crane wave compensation function verification device. Testing is performed through laser, gratings and a laser sensor, the grating and the laser sensor are arranged in the same device, and the device is provided with a bayonet with two movable ends and a fastening bolt. The front surface of the device is provided with the rectangular gratings which are arranged in parallel at intervals, the laser sensor is arranged on the surface opposite to the gratings, and the laser sensor is fixed on a heavy object hung on a crane through the movable bayonet and the fastening bolt. The test is carried out twice, a wave compensation function is closed during the first test, a laser light source is started, and the laser sensor collects an image at the moment; the wave compensation function is opened in a second test, the laser light source is started, and the laser sensor collects an image at the moment; and the wave compensation function of the crane is verified by analyzing the number of peak values in the two images. A test method is simple and efficient, and the test efficiency can be improved.

Description

technical field [0001] The invention relates to the field of offshore ship crane debugging, and specifically proposes a method for verifying the wave compensation function of the crane based on a laser device. Background technique [0002] Due to the rich sea resources and the rapid development of the sea economy, when the ship is operating at sea, it will have six degrees of freedom under the action of waves, which seriously affects the safety of the ship's sea operations, and the ship has high requirements for stability. As a result, the operation content is affected, so that the lifting equipment such as the crane on the ship is not very stable to place the items in the predetermined position, so the crane is equipped with a wave compensation system, and the functional effectiveness of the system needs to be tested. [0003] The Chinese patent "a crane wave compensation function verification method" with the publication number CN107651566A discloses a crane wave compensat...
