Problems solved by technology

The traditional way of dealing with it is that when holes need to be drilled at a specific location, the welder cuts the original pipe, and then welds the connecting sleeve. After use, it needs to be cut off for repair welding. It is extremely inconvenient for the electric welding operation of the distribution box

Embodiment Construction

[0034] See figure 1 , The pipe drilling equipment 100 of this embodiment includes a collar 1, a drill bit 2, and a jacking casing 3. The ferrule 1 is fixedly sleeved on the outside of the pipeline 4, the quick-connect buckle 12 fixedly connects the jacking casing 3 with the ferrule 1, and the drill bit 2 is rotatably assembled in the jacking casing 3.

[0035] See figure 2 versus Figure 5 , The hoop 1 includes a first part 10, a second part 11, a quick interface 13, a quick coupling 12 and an opening 14. The shape of the ferrule 1 is the same as that of the pipe, both of which are round. In this embodiment, the hoop 1 is divided into a first part 10 and a second part 11 along the diameter. The first end 101 of the first part 10 and the first end 111 of the second part 11 are movably connected to each other for rotation, and the second end 102 of the first part and the second end 112 of the second part can be fixed by The bolts 17 are fixedly connected to each other to fix the...

Abstract

The invention provides a pipeline hole opening device and a pipeline hole opening method. The pipeline hole opening device comprises a hoop, a drill bit and a jacking sleeve; the hoop comprises a fast connection buckle and a fast connector; the end portion of the jacking sleeve and the fast connector are fixedly assembled in the fast connection buckle; and the drill bit is movably assembled in the jacking sleeve. The method comprises that the pipeline hole opening device is provided. The pipeline hole opening device comprises the hoop, the drill bit and the jacking sleeve; the hoop comprises an opening, the fast connection buckle and the fast connector; the end portion of the jacking sleeve and the fast connector are fixedly assembled in the fast connection buckle; and the drill bit is movably assembled in the jacking sleeve and comprises a hole drilling part which is arranged opposite to the opening. The method includes the steps that the hoop is fixedly connected to the outer side of a pipeline needing hole opening in a sleeving manner; and the drill bit in the jacking sleeve is rotated and propelled towards the opening so that hole opening of the pipeline can be completed. By means of the pipeline hole opening device and the pipeline hole opening method, the hole opening operation can be fast completed, air supply and water supply are performed through air holes, and operation is stable and easy.

Description

Technical field [0001] The present invention relates to the technical field of pipeline drilling equipment, in particular to a pipeline drilling equipment including a drill bit, and also provides a pipeline drilling method using the pipeline drilling equipment. Background technique [0002] At present, most of the tunnel construction in our country uses air compressors and high-pressure wind to provide power and energy, mainly for drilling and blasting hand pneumatic drills, and shotcreting machines for spraying concrete. At the same time, high-pressure water is also needed in tunnel construction. Feng Shui pipe follows the tunneling of the face. [0003] In tunnel construction, it is often necessary to open the wind water pipe at a specific location and connect the corresponding construction equipment. Therefore, how to quickly open the wind water pipe has been a common problem in construction. The traditional way is to cut holes in the original wind water pipe when a hole is nee...
