Description

Manual drill capable of drilling under pressure

Technical Field

The utility model relates to a drilling utensil is pressed in area, especially a can press hand drill of driling in area.

Background

Originally, people need to add branch pipelines on pipelines operated under pressure, and need to close the pipelines first to completely discharge gas and liquid in the pipelines so as to be capable of drilling; in this way, production is affected. If the construction under pressure is extremely dangerous or cannot be realized.

Disclosure of Invention

The utility model aims at providing a hand drill which can drill under pressure and has simple structure and convenient operation, solving the difficult problem of the prior pipeline drilling construction under pressure, and the utility model aims at realizing the purpose and comprises a drill bit, a drill rod, a valve, a sleeve, a pipe joint, a movable screw pressing pipe, a press rod sealing seat, a sealing cover, a handle and a screw rod, wherein the drill bit is arranged at the top end of the drill rod, and the bottom end of the drill rod is connected with the handle; a movable screw pressing pipe is sleeved outside the drill rod, and a sleeve pipe and a pipe joint are sleeved outside the movable screw pressing pipe; one end of the sleeve is connected with a valve, and the other end of the sleeve is connected with a pipe joint.

The pressure bar sealing seat is connected with one end of the movable silk pressing pipe through threads, the other end of the pressure bar sealing seat is connected with the sealing cover through threads, and the outer side of the sealing cover is provided with a handle.

The pressure rod sealing seat is provided with a screw hole, and a pressure screw rod is connected in the screw hole through threads.

The inner diameter of one end of the pipe joint is larger than that of the other end of the pipe joint, the length of the inner diameter of the pipe joint is one half of that of the pipe joint, and internal threads are arranged in the pipe joint; the end of the pipe joint with small inner diameter is connected with the movable silk pressing pipe by screw threads, and the end of the pipe joint with large inner diameter is connected with the sleeve by screw threads.

The two ends of the sleeve are provided with external threads, and the external threads at the two ends of the sleeve are the same in length.

The movable silk pressing pipe is provided with an external thread.

The utility model discloses an application method: when the automatic drilling machine is used, the screw rod is rotated by hand, the screw rod drives the pressure rod sealing seat, the pressure rod sealing seat pushes the movable screw pressing pipe, the movable screw pressing pipe pushes the drill rod and the drill bit to be attached to a pipeline, the handle is rotated by hand, the drill rod is driven by the handle, the drill rod drives the drill bit to drill, after the drilling is completed, the pressure rod sealing seat is reversed, the movable screw pressing pipe is driven, the drill rod and the drill bit are returned, after the drill bit returns to a screw hole of the valve, the valve is immediately closed, and then other pipelines are connected to the valve.

The utility model discloses a meaning: firstly, drilling under pressure is carried out, so that the operation is safe; no leakage exists; secondly, the structure is simple, and the operation is convenient; thirdly, because the pressure is operated, the gas and the liquid in the pipeline do not need to be discharged completely, and the working efficiency is improved.
