A control tool that carries the operating carrier to move axially and circumferentially relative to the operating base

Abstract

A control tool that carries a working carrier to move circumferentially and axially relative to a working base, including an outer frame and an inner frame; the outer frame is connected to the outer receiving base, including left and right boxes, and the left box is screwed to the box cover to set a convex The keyway and guide rail opening, the right box is screwed to the box cover with convex keyway and guide rail opening, the side walls of the left and right boxes are separately equipped with hydraulic cylinders; the inner frame includes the left and right rotating bodies and the guide rails connected between the left and right rotating bodies. The convex key, the convex key of the left rotating body is buckled in the convex key groove of the left box and the left box cover, the convex key of the right rotating body is buckled in the convex key groove of the right box and the right box cover, and the left rotating body and the The piston rod of the hydraulic cylinder on the side wall of the left box is connected, and the right rotating body is connected to the piston rod of the hydraulic cylinder on the side wall of the right box; the axial and circumferential movement of the working carrier relative to the working base is realized, the bearing capacity is large, and installation and disassembly are easy. It is convenient and fast, and provides a simple and reliable pipeline local operation platform for unmanned connection of underwater pipelines.

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
