Полезная модель направлена на расширение диапазона диаметров разрезаемых труб с обеспечением совпадения начала и конца реза. Указанный технический результат достигается тем, что устройство, содержащее тележку, выполненную в виде несущей рамы с опорными колесами, охватывающие трубу приводные цепи и установленный на тележке режущий инструмент с приводом его врезания, редуктором, механизмом резания и механизмом подачи инструмента, выполнено с возможностью изменения межосевого расстояния колес и снабжено двумя независимыми механизмами натяжения цепи, узлом подачи смазочно-охлаждающей жидкости на инструмент и смонтированной на трубе цилиндрической направляющей с жестко закрепленным на ее боковой поверхности рельсом, при этом опорные колеса выполнены с канавками, ответными последнему. Несущая рама выполнена в виде пространственной конструкции из двух опорных щек, механически связанных стяжками и осями. Привод режущего инструмента выполнен в виде закрепленного на опорной щеке несущей рамы электродвигателя, оснащенного системой защиты от перегрузок, и редуктора, связанного с последним посредством зубчатой ременной передачи. Привод врезания инструмента содержит электродвигатель, оснащенный системой защиты от перегрузок, установленный на редукторе, выходной вал которого связан с винтовой парой шарнирно соединенной с редуктором привода режущего инструмента, и имеет возможность качания в опорах и поворота редуктора привода режущего инструмента, установленного в цапфах рамы, относительно оси параллельной оси трубопровода. 1 з.п. ф-лы, 9 ил.

An electric saw device having two saw blades being arranged for allowing the two saw blades to be driven to rotate in opposite directions. The two saw blades are respectively formed with circular grooves on their inner surfaces at positions corresponding to each other while enabling the centers of the two circular grooves to aligned with the rotation axes of corresponding saw blades. The electric saw device has a plurality of steel balls, each being sandwiched between the two saw blades while insetting into the circular grooves simultaneously, by that the saw blades are separated from each other by a specific interval. Accordingly, when the two saw blades are rotating in opposite direction, each of the steel balls is acting as a roller bearing for maintaining the two saw blades to be properly separated from each other, and thus preventing the two saw blades from overheating and softened by friction.

Front feet are provided at a lower part of a cutting-machine main body via a foot holder. Furthermore, a slider positioned on a front side relative to the front feet is provided at the lower part. When a workpiece to be cut is to be cut by a blade, the cutting-machine main body is tilted so as to let the blade go down. When the cutting-machine main body is tilted, a state where the front feet are in contact with the workpiece is switched to a state where the slider is in contact with the workpiece. Then, by moving the cutting-machine main body forward while sliding the slider on the workpiece, the workpiece is cut by the blade. In the cutting operation, the front feet can get away from the workpiece. Therefore, damage of the front feet can be prevented, and the running cost can be suppressed.

A cutting indicator includes an adjusting base pivotally mounted to a saw arm of a circular saw, a lens mounted in the saw arm, and a laser generator mounted on the adjusting base. When a laser beam generated by the laser generator passes through the lens, the laser beam is converted to a laser plane that forms a laser indicating line on the workpiece to be cut by the circular saw. Adjusting the adjusting base causes the plane beam to be quickly switched between a predetermined first plane position and a predetermined second plane position that are aligned substantially parallel to two opposing lateral planes of the circular saw blade. Thus, quick adjustment of the laser indicating line can be easily achieved. 1. A cutting indicator used in a circular saw comprising a worktable , a saw arm pivotally mounted at said worktable and a circular saw blade pivotally mounted to said saw arm and defining two opposing lateral planes , the cutting indicator comprising:an adjusting base pivotally connected to said saw arm;a lens mounted in said saw arm corresponding to said adjusting base; anda laser generator arranged in said adjusting base corresponding to said lens and adapted to generate a laser beam through said lens to form a plane beam on said worktable, said plane beam switchable between a predetermined first plane position and a predetermined second plane position subject to pivoting of said adjusting base relative to said saw arm, said predetermined first and second plane positions aligned substantially parallel to said two lateral planes of said circular saw blade.2.
