Pipe opening device and method of use thereof

Abstract

The invention discloses a pipe opening device and a method for using the pipe opening device. The pipe opening device includes a pipe opening drill body and a pipe opening drill. The pipe opening drill includes a first drill bit, and a first end of the first drill bit is provided with a first cutting head. The second end of the first drill bit is provided with a first connection head, and the first drill bit is provided with a raised locking thread on the circumference between the first cutting head and the first connection head, so The major diameter of the locking thread is larger than the outer diameter of the first cutting head. Through the setting of the clamping thread, the first drill bit can enter and exit the drilling hole of the pipeline while clamping the drilling hole. The open drill body includes a rotary power mechanism, a propulsion power mechanism and a drill rod, and the rotary power mechanism drives the drill The rod rotates and the propulsion drive mechanism moves the drill rod.

Description

technical field [0001] The invention relates to the field of pipe openings, in particular to a pipe opening device and an application method thereof. Background technique [0002] The use of pipes is very common, such as water pipes, sewage pipes, etc. Due to the requirements of use, it is often necessary to open various branch ports on the pipes and install valves, etc. , When maintenance is required and when branch outlets are opened, water cut-off operations are required. [0003] So people have invented a kind of open-ended drill, which has realized non-stop water operation, but the open-ended drill is divided into two parts, the first part is the drill bit with traction effect, and the drill bit is provided with an undercut mechanism behind the drill bit. After passing through the inside of the pipe along the drill bit, it will open due to gravity or other elastic mechanisms, so at this time the traction drill bit is stuck and cannot be pulled out. Continue to use the ...

[0002] The use of pipes is very common, such as water pipes, sewage pipes, etc. Due to the requirements of use, it is often necessary to open various branch ports on the pipes and install valves, etc. , when maintenance is required and when a tributary outlet is opened, it is necessary to stop the water operation

[0003] So people have invented a kind of open-ended drill, which has realized non-stop water operation, but the open-ended drill is divided into two parts. After passing through the inside of the pipe along the drill bit, it will open due to the action of gravity or other elastic mechanisms, so the drill bit for traction is stuck and cannot be pulled out at this time. Continue to use the large drill bit for cutting the pipe to open the pipe, and then use the traction The active drill bit takes out the fragments, but there is a problem with this structure. After the traction drill bit passes through, an undercut is formed and cannot be taken out. If there is a problem with the large drill bit used for cutting pipes and needs to be taken out, it cannot be taken out due to the undercut of the traction drill bit. Finally, more cumbersome steps are required to remove the undercut drill bit, which increases the construction cost and difficulty
