Abstract

The invention discloses a control method of hydraulic cutting equipment, and belongs to the technical field of hydraulic cutting. The control method of the hydraulic cutting equipment comprises the steps that external equipment to be cut is located between a first guide part and a second guide part through at least one operation of moving a walking device and rotating a cantilever around a first axis; the walking device is moved so that the walking device can continuously get close to the external to-be-cut equipment, and the external to-be-cut equipment can stretch into the position between the first guide part and the second guide part till the external to-be-cut equipment makes contact with the first guide part and the second guide part; and the cutting device is controlled to cut the to-be-cut position of the external to-be-cut equipment. By means of the technical scheme, even if hydraulic cutting equipment needs tool retracting buffering in the cutting process, through the steps, the cutting device can move to the position before tool retracting again, the tool feeding position is the same, the positioning precision is high, the cutting efficiency is not affected, and the difficulty of visual inspection is reduced.

Description

technical field [0001] The application belongs to the technical field of hydraulic cutting, and in particular relates to a control method of hydraulic cutting equipment. Background technique [0002] After a blowout occurs at the wellhead, the temperature at the center of the blowout will reach above 1200 degrees Celsius. The site needs to use fire monitors to spray water, and use high-pressure hydraulic cutting equipment to cut the wellhead device. [0003] Generally, the cutting speed of hydraulic cutting equipment is slow under high temperature conditions and is easily affected by high temperature. Therefore, after cutting for a period of time, it is necessary to withdraw the hydraulic cutting equipment from the high temperature area, and let the hydraulic cutting equipment buffer for a period of time before continuing to cut. Therefore, it is necessary to ensure that the feeding position is the same for each feeding and cutting. In the related art, when performing cuttin...
