Detailed Description

As shown in fig. 1, a drill rod 20 is arranged in a tubular cavity of a tubular body 10 of the manual tapping device, a drilling tool 21 is arranged at the end part of the drill rod 20 exposed at the lower end of the tubular body 10, a hand wheel wrench 40 is arranged at the end part of the drill rod 20 exposed at the upper end of the tubular body 10, a guide sleeve 11 is arranged in the tubular body 10, a sealing ring 111 is arranged between the guide sleeve 11 and the drill rod 20, an external thread 12 is arranged on the outer pipe wall of the upper section of the tubular body 10, the external thread 12 is matched and connected with an internal thread section of a drill sleeve 30, the hand wheel 31 is connected with the periphery of the drill sleeve 30, the upper sleeve top of the drill sleeve 30 pushes the drill rod 20 to move downwards when the drill sleeve moves downwards in a spiral mode, a pipe clamp or a half joint B is connected to the pipeline A to be tapped, a ball valve C is connected to the threaded joint on the pipe clamp or the half joint B in a sealing mode, and the ball valve C is connected to the lower end threads of the tubular body 10 in a sealing mode.

In the scheme, the pipe clamp or the half joint B is connected to the pipeline A to be perforated, the pipe clamp or the half joint B can be used for realizing reliable sealing connection with the pipeline A to be perforated, the ball valve C is connected through the pipe joint on the pipe clamp or the half joint B, the tubular body 10 is connected with the ball valve C, and sealing between pipe threads can be formed by winding raw rubber belts. The hand wheel wrench 40 rotates to drive the drilling tool 21 to rotate, meanwhile, the hand wheel 31 is rotated, the tubular body 10 is in threaded connection with the drill bushing 30, and the tubular body 10 is fixedly connected with the ball valve C, the pipe clamp B and the pipeline A to be drilled and then keeps static, so that the upper cylinder bottom of the drill bushing 30 is pressed against the drill rod 20 to move downwards when the drill bushing 30 moves downwards in a spiral mode, and the drilling tool 21 has the rotation and downward movement processes to complete drilling operation. The ball valve C may be replaced with other types of gate valves.

In order to adapt the tubular body 10 to the ball valve C, considering the various specifications of the ball valve C, including the dimensions and the form of the internal and external threads, a transition is made by providing a coupling 50, i.e. the lower end of the coupling 50 has a threaded section for connecting the ball valve C, in which the diameter of the through hole of the valve core is greater than the diameter of the drilling tool 21. The scheme is that the connection with the machine is ensured through changing the pipe joints 50 with different specifications, and the machine can be in adaptive connection with various ball valves C.

Preferably, a gate valve 60 is connected to the pipe body 10 above a portion of the pipe joint 50 connected to the lower end of the pipe body 10.

Under the condition that the pipeline A to be drilled in the pipeline is a combustible medium, the drilling operation is dangerous, so that arc extinguishing agent, cooling agent and the like can be filled into a turning part by additionally arranging the gate valve 60, and the safety of the drilling operation is ensured; in addition, the ball valve C is closed after the hole is opened, the gate valve 60 is opened, and toxic and harmful media are safely collected through the gate valve 60 or slurry is recycled and the like.
