Abstract

A high-altitude portable pipeline cutting machine relates to a pipeline cutting machine, which aims at the problems of the portable pipeline cutting machines, such as fussy mounting operation, heavy weight, low precision, high cost, large radius of gyration, and unsuitable use in working aloft. A hinged annular shelf is fixedly connected with a knife rest; a running mechanism seat is fixedly connected with the hinged annular shelf; a running mechanism cavity is arranged in the running mechanism seat; a chamber of the running mechanism cavity is arranged on the knife rest; two running mechanisms are respectively arranged in the running mechanism cavity and the chamber of the running mechanism cavity; a large-diameter crown arc groove and a small-diameter crown arc groove which are mutuallycommunicated are arranged on the knife rest and are used as running cavities of a knife body frame; a knife body frame assembly is arranged in the running cavity of the knife body frame; the upper end of the knife body frame assembly is limited by a rotating cover arranged on the upper end surface of the knife rest; a locating staff gauge is fixedly arranged in a staff gauge mounting hole on the knife rest. The invention has light weight and small radius of gyration, good compatibility and low cost; moreover, the specification span of the pipeline which can be cut by the machine is large. Besides, the high-altitude portable pipeline cutting machine is suitable to be used for working aloft.

Description

Technical field [0001] The invention involves a pipeline cutting machine. Background technique [0002] In the pipeline construction, pipelines need to lead the branch pipelines or add valve and other pipes in turning, branches, and working points.If you do n’t go up at high altitude, you ca n’t go up, so you can only measure the size in the air, and then return to the ground to get the feeding. The work is cumbersome.At present, the pipeline cutting machines on the market are mostly used on the ground. The equipment is complex and large. Although the accuracy is high, the installation operation is inconvenient and it is not suitable for high -altitude operations.There are also portable pipeline cutting machines. One is to use flame cutting methods. The installation is more complicated, the construction accuracy is low, and the weight is large (generally about 15-20 kg); the other is to use cold cutting methods., High cost, poor stability, affecting construction accuracy, large r...
