Abstract
The utility model discloses a pressure driller, which comprises a drill pipe and a drill bit provided on the end section of the drill pipe. The pressure driller is characterized in that a plug is sheathed on the drill pipe in such a manner that the plug can move back and forth on the drill pipe, and a sealing material is arranged on the combination section of the plug and the drill pipe. The driller can be used for drilling holes on pipes with water pressure and oil pressure. The driller solves the problems in drilling holes on water supply pipes without cutting off water and gas under normal heat-supply state.
Description
Technical field
The utility model relates to power tool, specifically a kind of hole making drill that is applicable to perforate on band pressure pipe body.
Background technology
At present, perforate on steel pipe uses electric drill to carry out operation usually.This method generally only is suitable for perforate on blank pipe.And in the practice of construction operation, usually need perforate on the pipeline that has hydraulic pressure or oil pressure, as at the new heating equipment of tipping on operating caliduct just.Thereby, when operation in the past, must stop the operation of whole or local warm-air feed earlier, bleed off ducted ponding again after, but just perforate operation.
The utility model content
The purpose of this utility model just provides a kind of hole making drill that is suitable for perforate on band pressure pipe body, to be convenient for people to the operation in pipeline with pressure.
The purpose of this utility model is achieved in that
The pressure-bearing hole making drill that the utility model is designed includes drilling rod, and the end of drilling rod is provided with opening bit, and the main points of its design are to be socketed with plug wire on drilling rod, and this plug wire is movable before and after can be on drilling rod, is provided with envelope in the joint portion of plug wire and drilling rod and expects.
The pressure-bearing hole making drill of design like this can perforate on the pipeline that has hydraulic pressure, oil pressure.It has solved similar under normal heating state, does not cut off the water, stops the supple of gas or steam, just the problem that can't punch on water supply line.
The utility model is simple in structure, and is easy to use, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model user mode.
The specific embodiment
The utility model as shown in Figure 1, its drilling rod 3 is basic identical with common drilling rod, in the end of drilling rod 3 opening bit 1 is arranged, and is socketed with plug wire 4 on the body of rod of drilling rod 3, is provided with rubber seal envelope material 6 in the joint portion of plug wire 4 and drilling rod 3.In order further to improve the sealing effectiveness of plug wire 4, on envelope material 6, preferably be provided with housing pin 5 again.Plug wire 4, rubber seal envelope material 6 and housing pin 5 be common to constitute a plug that moves before and after can be on drilling rod 3.When actual job, can be as shown in Figure 2, prepare one section silk of position welding 8 of punching earlier at pipeline 7 with pressure, on silk 8, a valve 9 is installed, again the plug wire on the drilling rod 34 is screwed on the valve 9, the afterbody of drilling rod 3 is fastened in the electric drill clamp 10.When punching, with valve open, open electric drill, opening bit 1 passes through valve port and promptly pipeline 7 is carried out perforate.Perforate finishes, and opening bit 1 retreats to plug wire 4, behind the valve-off, unloads plug wire 4 again, has finished the perforate operation of pipeline with pressure thus.
Claims (2)
1, a kind of pressure-bearing hole making drill, the end that includes drilling rod (3), drilling rod (3) is provided with opening bit (1), it is characterized in that being socketed with on the drilling rod (3) plug wire (4), and plug wire (4) is provided with envelope material (6) with the joint portion of drilling rod (3).
2, pressure-bearing hole making drill according to claim 1 is characterized in that said envelope material (6) is provided with housing pin (5).
