Large hollow pipe drilling machine

Abstract

The invention discloses a large hollow pipe drilling machine. The large hollow pipe drilling machine comprises a base; an upright column is fixedly arranged on the base; a cross bar penetrates throughthe upright column; the cross bar is perpendicular to the upright column; the end part, close to the upright column, of the cross bar is fixedly connected with a rotating shaft of a driving motor; adrilling mechanism is fixedly arranged at one end, far away from the upright column, of the cross bar; the drilling mechanism comprises a connecting plate fixedly arranged on the cross bar, four sliding chutes I formed in the connecting plate in a cross shape, drilling machines slidably arranged on the sliding chutes I, and driving devices connected with the drilling machines through connecting rods; drill bits of the drilling machines face the outside of the connecting plate; and the driving devices are fixedly mounted on the connecting plate. The large hollow pipe drilling machine is novel in structure, can drill holes in four positions of a large hollow pipe at the same time, and is convenient to operate, so that the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of drilling machinery and equipment, in particular to a large-scale hollow pipe drilling machine. Background technique [0002] Drilling machine is a general term for machinery and equipment that leaves cylindrical holes or holes on the target by means of rotary cutting or rotary extrusion with a tool that is harder and sharper than the target, also known as drilling rig, punching machine, Drilling machine, through hole machine, etc. [0003] Large hollow pipes are used in a wide range of applications, but many industries need to drill holes on the surrounding walls of pipes before using large hollow pipes. At present, most drilling machines can only drill holes in one position of large pipes at the same time. Therefore, When it is necessary to drill holes in other positions, it is necessary to move the drilling machine or the pipe, which is very inconvenient to operate and takes a lot of time, which greatly affects ...

[0003] Large hollow pipes are used in a wide range of applications, but many industries need to drill holes on the surrounding walls of pipes before using large hollow pipes. At present, most drilling machines can only drill holes in one position of large pipes at the same time. Therefore, When it is necessary to drill holes in other positions, it is necessary to move the drilling machine or the pipe, which is very inconvenient to operate and takes a lot of time, which greatly affects the work efficiency
