Embodiment Construction

[0016] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 to Figure 3 , graded pipe cutters, including a pipe cutter main frame and more than two groups of pipe cutting mechanisms arranged at intervals along the first direction on the pipe cutter main frame;

[0018] The pipe cutting direction of the pipe cutting mechanism is perpendicular to the first direction, and the pipe cutting gaps of more than two groups of the pipe cutting mechanisms arranged along the first direction gradually decrease.

[0019] It can be seen from the above description that the beneficial effect of the present invention is to provide a graded pipe cutter, in which two or more groups of pipe cutting mechanisms are arranged at intervals along the first direction on the main frame of the pipe cutter. The direct...

Abstract

The invention relates to the field of pipeline maintenance equipment, and particularly relates to a graded pipe cutter. The graded pipe cutter comprises a pipe cutter main frame and two or more sets of pipe cutting mechanisms arranged on the pipe cutter main frame in the first direction at intervals; and the pipe cutting direction of the pipe cutting mechanisms is perpendicular to the first direction, and the pipe cutting gaps of the two or more sets of pipe cutting mechanisms arranged in the first direction are gradually reduced. The graded pipe cutter is good in pipeline clamping and plugging effect and high in clamping stability, the risk of secondary leakage can be reduced through the multi-stage cutoff structure, safety is good, and the problem of cutoff failure caused by pipeline cracking easily caused by a cutoff mode of one-time cutoff can be avoided.

Description

technical field [0001] The invention relates to the field of pipeline maintenance equipment, in particular to a graded pipe cutter. Background technique [0002] In pipeline emergency repair operations, it is generally necessary to close the upstream and downstream valves of the pipeline first, and then perform emergency repairs after emptying the residue in the pipeline, or clamp the pipeline through a pipeline cutting device, and stop the residue in the pipeline before performing emergency repairs. Although the traditional pipe cutting device has a simple structure and low cost, the pipe clamping and sealing effect is poor, and the clamping stability is poor, and secondary leakage is prone to occur, which has certain hidden dangers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a graded pipe cutter with good clamping and sealing effect and strong stability. [0004] In order to solve the above-mentioned tech...
