Control machine capable of carrying operation carrier to perform axial and circumferential motions relative to operation matrix

Abstract

The invention relates to a control machine capable of carrying an operation carrier to perform axial and circumferential motions relative to an operation matrix, which comprises an outer frame and an inner frame, wherein the outer frame is connected with an external bearing matrix and comprises a left box and a right box; a left box bolted box cover is provided with a convex keyslot and a guide rail opening; a right box bolted box cover is provided with a convex keyslot and a guide rail opening; one side wall of the left box and one side wall of the right box are respectively provided with a hydraulic cylinder; the inner frame comprises a left rotator, a right rotator and a guide rail connected between the left and right rotators; the left and right rotators are respectively provided with a convex key; the convex key of the left rotator is clamped in the left box and the convex keyslot of the left box cover; the convex key of the right rotator is clamped in the right box and the convex keyslot of the right box cover; the left rotator is connected with a hydraulic cylinder piston rod arranged on the side wall of the left box; and the right rotator is connected with a hydraulic cylinder piston rod arranged on the side wall of the right box. The control machine of the invention realizes the axial and circumferential motions of the operation carrier relative to the operation matrix, has the advantages of high bearing capacity, and convenient and quick assembly and disassembly, and provides a simple-control and reliable pipeline local operation platform for subwater pipeline unmanned connection.

Description

technical field [0001] The invention relates to automatic mechanical equipment, in particular to a control tool for carrying a working carrier to move axially and circumferentially relative to a working base. Background technique [0002] Modern oil, gas, nuclear energy, chemical and water industries require a large number of closed pipelines. These online and in-service pipelines require daily maintenance and inspection, and operators or robots are required to carry them during maintenance and inspection. Maintenance tools and testing instruments perform local operations on the pipeline, such as carrying ultrasonic transducers for weld inspection, carrying welding equipment for pipeline welding, etc.; in addition, there will be many super-long pipelines that need to be cut and processed into suitable lengths during pipeline processing. Pipeline: In pipeline laying, maintenance and monitoring, etc., the work carrier needs to be able to move axially and circumferentially rela...

Problems solved by technology

Although there are many kinds of implements that enable the work carrier to move in the circumferential direction and the axial direction relative to the work base, these machines only have a single movement function, that is, carry the work carrier alone to realize the circumferential movement relative to the work base, or carry the work The single carrier realizes the axial movement relative to the working base, which results in the need to use two kinds of tools to complete the purpose of the working carrier moving relative to the working base in the circumferential and axial directions. The operation is complicated and the construction efficiency is low.

Furthermore, the existing commonly used machines for carrying the work carrier to achieve circumferential movement relative to the working pipeline have soft-toothed belt-type and planetary gear-type control tools, and the known disadvantage of the soft-toothed belt-type control tools is the carrying capacity. and low motion precision, poor motion stability, etc.; in the patent (03129275.5) of the invention titled Pipeline Circumferential Rotation Control Mechanism, the proposed planetary gear type pipeline Circumferential Rotation Control Mechanism has limited working environment and installation requirements Advanced features; the existing common axial movement control mechanisms relative to the work base include telescopic type and guide rail type, which can only achieve the purpose of axial movement of the work carrier relative to the work base
