Wire saw for cutting pipelines

Abstract

The invention discloses a wire saw for cutting pipelines. The wire saw comprises a support frame, a tension self-adaptation adjusting mechanism, a cutting mechanism and a clamping mechanism, wherein the cutting mechanism and the clamping mechanism are respectively disposed on two sides of the support frame; the clamping mechanism comprises a front clamp plate, a rear clamp plate, a left clamping jaw, a right clamping jaw, a left air cylinder and a right air cylinder, and the left air cylinder and the right air cylinder are mounted between the front clamp plate and the rear clamp plate; the cutting mechanism comprises a frame body, a drive wheel, a tension wheel and two driven wheels, the drive wheel, the tension wheel and the two driven wheels are respectively located at four corners of the frame body, an adjusting telescopic support rod is disposed between the other end corner of a main support and the frame body, and the tension self-adaptation adjusting mechanism is disposed between the other end corner of a driven support and the frame body; the tension self-adaptation adjusting mechanism further comprises a connecting shaft sleeve, a movable pin, a connecting plate, a slide plate, a hydraulic cylinder and loop bar, and a spring sleeves the loop bar. The wire saw has the advantages that the wire saw is high in reliability, stability, safety and universality and simple to operate, work stability is increased, the requirements of various pipelines can be met, the universality and operability of the wire saw are increased.

Description

Technical field [0001] The invention relates to a wire saw machine for cutting pipelines, and relates to a wire saw machine for pipeline installation in the chemical, natural gas, nuclear power, petroleum and other industries. Background technique [0002] At present, the cutting operations of large-diameter or multi-material-filled pipelines in offshore petroleum engineering and nuclear power industry use cold cutting, hot cutting or explosive cutting. The cold cutting method is technically difficult, so it is rarely used, while the hot cutting method is not. It is suitable for underwater operations, and the explosive cutting method is not environmentally friendly. In recent years, the diamond wire saw cutting technology has been developed abroad for use in underwater large-diameter or multi-material-filled pipelines such as offshore oil platform jackets or pile foundations, and large-diameter or multi-material-filled pipelines on land such as nuclear power industry. The cuttin...
