Embodiment Construction

[0034] See figure 1 , 2 , 3, 4, 5. In the electric pipeline internal counterpart of the present invention, its counterpart working part, driving part and braking part are all connected with the motor;

[0035] The counterpart working part is three sets of the same coaxial counterpart tensioning mechanism, and the front counterpart tensioning mechanism 5 and the middle counterpart tensioning mechanism 7 are bonded together;

[0036] The front counterpart tensioning mechanism 5 and the arc-shaped guide cage front body 1 constitute the front support part;

[0037] The middle counterpart tensioning mechanism 7 and the rear counterpart tensioning mechanism 13 located at both ends of the rear body 15 form a rear support part with the rear body 15;

[0038] The middle of the front counterpart tensioning mechanism 5 and the middle counterpart tensioning mechanism 7 is fixedly connected with a disc-type two-way guide column 6, and the rear counterpart tensioning mechanism 13 at the ...

Abstract

The invention discloses an electric internal clamp for a pipeline. The electric internal clamp for the pipeline comprises a rack, a motor, a driving device and butt working portions, wherein the butt working portions and the driving portion are respectively connected with the motor; a braking portion connected with the motor is also arranged. The internal clamp disclosed by the invention is divided into a front portion and a rear portion; mainly by means of three sets of identical coaxial line butt tensioning mechanisms driven by the motor, the center line of the internal clamp is superposed with that of the pipeline; the electric internal clamp for the pipeline is simple and reasonable in structure, low in duty ratio, convenient to adjust, small in inertia, reliable in braking, good in control system robustness and high in butt precision, and is capable of directly utilizing electric energy; compared with hydraulic and pneumatic internal clamps, the electric internal clamp for the pipeline has the advantages that the construction cost can be reduced, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to pipeline construction technologies for oil and gas, coal, water conservancy, etc., in particular to a counterpart device for pipeline counterpart welding, especially an electric internal counterpart for pipelines. Background technique [0002] In pipeline construction, the butt welding of pipes is to weld the laid pipes one by one through the pipe-pipe ring weld combination. Before welding, the nozzles of the two pipes to be welded must be aligned so that the butt nozzles can meet the roundness, misalignment and alignment gap required by the relevant specifications. This part of the work occupies an important position in pipeline construction. The pipe matching device is a professional equipment that realizes real-time, fast and accurate nozzle grouping in pipeline construction and provides technical guarantee for pipeline welding; in the construction of long-distance transmission pipelines at home and abroad, internal matchin...
