Articulated petroleum pipeline cutting device

Abstract

The invention discloses an articulated petroleum pipeline cutting device. An arc strip is arranged between supporting strips in a connected manner, a lower cutting plate is arranged between the supporting strips and is connected to the same, sliding rails are adhered to the supporting strips and contact with the arc strip and the lower cutting plate, an upper cutting plate is arranged between the supporting strips and contacts with the sliding rails, the sliding rails are fitted into the upper cutting plate, the lower cutting plate is provided with a shaft, and the shaft penetrates the lower cutting plate; one supporting strip is provided with a rotary shaft penetrating the supporting strip, the outer wall of the supporting strip is provided with a clamping sleeve, two ends of the rotary shaft penetrate the clamping sleeve, the clamping sleeve is capable of rotating around the rotary shaft, one ends of the side wall of the supporting strip and lower cutting plate are both arranged in the clamping sleeve, one end of the clamping sleeve adjacent to the supporting strip is recessed to form a clamping groove, and two ends of the shaft are both arranged in the clamping groove and contact with the wall of the clamping groove. The device is convenient to carry and is capable of being disassembled and penetrating a pipeline radially conveniently.

Description

technical field [0001] The invention relates to a device, in particular to a petroleum pipeline hinged cutting device, which belongs to the field of petroleum machinery. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. It is composed of a mixture of different hydrocarbons, and its main component is alkanes. In addition, petroleum also contains elements such as sulfur, oxygen, nitrogen, phosphorus, and vanadium. Petroleum is mainly used as fuel oil and gasoline, which constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. Oil is mostly hydrocarbons. It is composed of a mixture of different hydrocarbons. The chemical elements that make up petroleum are mainly carbon (83% ~ 87%), hydrogen (11% ~ 14%), and the r...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the above existing equipment is inconvenient to carry when cutting oil pipelines in the field, and cannot be inserted into the pipeline. A hinged cutting device for oil pipelines is designed. The equipment is easy to carry and is set as a movable structure , can be disassembled, and can be directly inserted into the pipeline from the radial direction, which solves the problem that the existing equipment is inconvenient to carry when cutting the oil pipeline in the field, and cannot be inserted into the pipeline
