A directional detachment device for butt joint flanges

Abstract

The invention discloses a directional detachment device for butt joint flanges, and relates to the technical field of mechanical detachment devices. The invention comprises a clamping guide frame which is clamped and installed on the flange of the pipeline; one end of the clamping guide frame is installed with a first flange positioning component for clamping the flange of one side of the pipeline; the other end of the clamping guide frame is slidably fitted for The second flange positioning component snaps on the pipe flange on the other side; the snap-fit ​​guide frame is slidably fitted with an opening assembly for expanding two adjacent flanges, and the opening assembly is located between the first flange positioning assembly and the second flange positioning assembly. Between the flange positioning components; the second flange positioning component is threadedly connected with four spreading screw rods, and one end of the spreading screw rods abuts against the clamping guide frame. In the present invention, the first flange positioning component and the second flange positioning component clamp the flange of one side of the pipeline respectively, and the screw rod is stretched to support and increase the distance between the flanges of the two pipelines, and the overall cooperation is used for docking The directional detachment device of the flange is quick and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of mechanical dismantling devices, in particular to a directional dismantling device for butt joint flanges. Background technique [0002] Pipeline transportation is often used in gas transmission, water transportation, and industrial raw material transportation. Pipeline transportation has the characteristics of long-term and stable transportation. However, the length of the pipeline is long, and maintenance and repair are difficult. In the process of partial maintenance, it is necessary to intercept and evacuate the local pipeline connection section after treatment. The existing evacuation methods are mostly truncation or opening treatment. The existing problem is re-welding Afterwards, hidden safety hazards are left, and the inside of the pipeline is polluted during the welding process, which is not conducive to pipeline drainage and maintenance operations. When installing gauges and other devices in the...
