Abstract

The invention discloses a pipe orifice correction device capable of achieving rapid alignment. The pipe orifice correction device comprises a correction hydraulic mechanism, a rotary clamping mechanism, a lifting mechanism, a walking mechanism, a hydraulic pump station and a control cabinet. The correction hydraulic mechanism is connected to an installation plate of the lifting mechanism through the rotary clamping mechanism. The lifting mechanism is installed in the walking mechanism. According to the pipe orifice correction device, the flexible rotary clamping mechanism and a PLC automatic control system are adopted, a device body is provided with a plurality of gravity center lifting points, and it is effectively guaranteed that a correction jack rapidly and accurately finds a correction point; a flexible connector has a certain compensation effect on relative position deviation caused by the correction jack connected with the flexible connector in the correction process, the correction jack can be allowed to achieve automatic alignment to a certain degree, and it is guaranteed that the correction pushing direction is perpendicular to the pipe wall all the time; and a rotation mechanism can drive the correction jack to rotate at an angle of 360 degrees around the axis of a pipeline in a pipe orifice, the correction point can be conveniently, rapidly and accurately found, thecorrection working condition is effectively improved, the working efficiency is improved, the correction precision is guaranteed, and the correction quality is improved.

Description

technical field

[0001] The invention relates to a correction device, in particular to a fast alignment correction device and a correction method thereof. Background technique

[0002] For large-diameter steel pipes, it is inevitable that the mouth of the pipe will be congenitally out of round during manufacturing and processing. During the storage, transfer and use of the steel pipe, the mouth of the pipe will also be deformed and out of round due to extrusion and collision. The out-of-roundness of the nozzle seriously affects the installation and docking, and it must be corrected and returned to the circle first. There are many methods for nozzle calibration. The current mainstream method is to use a hydraulic jack to radially prop up the tube wall inside the nozzle for calibration. The calibration accuracy is guaranteed by controlling the stroke of the jack. This method is effective. Compared with general mechanical The formula calibration method saves much time and effor...
