Abstract
The utility model relates to a manual hole opener for a pipe with pressure, which is applied to manually opening a hole of the pipe with the pressure. An outer thread is arranged at the lower end of an outer pipe, an inner-thread cover plate is welded at the upper end of the outer pipe, a pushing drum is connected with the interior of a central screw hole of the inner-thread cover plate, and the outer wall of the pushing drum is provided with a thread; a drilling rod is arranged in the pushing drum, a cylindrical stage is arranged at the lower end of the drilling rod, and a drilling head is fixedly at the lower end of the cylindrical stage; a central line of a drill bit and a central line of the drilling rod are arranged on a same straight line; and a rectangular fixing block is fixed at the upper end of the drilling rod and a flow guiding pipe is welded on an outer pipe wall. The manual hole opener for the pipe with pressure, disclosed by the utility model, has the effects that medium in a pipe is not leaked to cause pollution on environment when a hole is pored on the pipe with the pressure.
Description
Technical field
The utility model relates to petroleum pipeline, and the tailored version instrument that carries out the manual press and open holes of low-pressure line in each link is failed, stores, processed to particularly a kind of manual press and open holes device at fluid media (medium) production, collection
Background technology
, need transform pipe network, when pipeline de-plugging or production flow line are planted the first-class operation of emptying, must stop well, stopping production sometimes because the process pipelines layout is unreasonable in the oil field, carry out emptying, pipeline purging could be operated.Certainly will influence rate when driving a well like this, the normal operation that influence is produced, and then influence output.The petroleum pipeline that has is loosening because of corroding build-up of pressure table and pipeline junction.Then need stop well, pipeline purging as if pressure tapping is welded on the pipeline again comprehensively, have a strong impact on rate when driving a well, cause very big economic loss, and surrounding enviroment are polluted.Similar need be on production flow line the operation of press and open holes, in actual production, run into a lot.
Chinese patent publication number: CN3146864 provides a kind of " hole making drill ", mainly is made up of external support coupling part and inner bit part two parts.Through rotary drilling-head top keyway end, make the drill bit precession carry out perforate.Its major defect is: can only be used for holing on the plane, can't accomplish on curved surface and hole.Because of there not being sealing device, must make the internal flow dielectric leakage after the perforate simultaneously.The use limitation is big.
Chinese patent publication number: CN201848563U provides a kind of " pipe pressurized boring device ", and hole making drill is passed thin mouthful of leading screw, and the hole making drill handle is fixed in thin mouthful of leading screw tail end; On thin button leading screw, left side flange, gate valve, right side flange and airtight and watertight padding differential are installed successively.Under air-tight state, on in-service pipeline, process circular port with the machine cut mode.When the labour pipeline need install arm additional, under the situation of the normal conveying that does not influence pipeline, safety, efficient, the old pipeline modification work of environmental protection ground completion.
The utility model content
The purpose of the utility model is: provide a kind of band pressure pipeline manual hole making drill, can on pipeline with pressure, carry out perforate, overcome the production flow line perforate before, must the emptying pressure release cause the deficiency of environmental pollution and economic loss.
The technical scheme that the utility model adopts is: the manual hole making drill of band pressure pipeline; Mainly be made up of drill bit, outer tube, internal thread cover plate, propelling tube, drilling rod, fixed block and mozzle, it is characterized in that: there is external screw thread the lower end of outer tube, and the upper end of outer tube is welded with an internal thread cover plate; The internal thread cover plate has center screw; In the center screw of internal thread cover plate, be connected with one and advance tube, advance the outer wall of tube that screw thread is arranged, in advancing tube, a drilling rod is arranged; There is cylindrical step the lower end of drilling rod, is fixed with drill bit in the lower end of cylindrical step; The center line of drill bit and the center line of drilling rod are on same straight line; Be fixed with rectangular fixed block in the upper end of drilling rod, spanner can be fixed on the fixed block, and rotary spanner can make drilling rod drive the drill bit rotation, and tube wall is holed; On outer tube wall, be welded with a mozzle.
For the ease of setting upright, on the outer wall that advances tube, be welded with handle.
Fig. 1 is consulted in the use of the manual hole making drill of summary band pressure pipeline.When on pipeline with pressure, being welded with nipple joint, when carrying out perforate, outer tube 2 lower end screw threads are fixed on the nipple joint.Rotation advances tube 4, makes drill bit 1 compress pipeline external wall with pressure.Rotary drilling-head rotates on one side and advances tube 4 on one side, and drill bit 1 drills through pipeline walls.After pipeline walls was drilled through, the liquid in the pipeline flowed out, and flowed away through the flexible pipe that connects on the mozzle 8.
The beneficial effect of the utility model: the manual hole making drill of the utility model band pressure pipeline, can on pipeline with pressure, carry out perforate, medium can not leak in the pipe, therefore can not pollute environment.Before overcoming the production flow line perforate, must the emptying pressure release cause the deficiency of environmental pollution and economic loss.Need not the pipeline purging that stops production like this, just can carry out the tap operation of production flow line, in whole perforate operation process, do not have the dielectric leakage phenomenon.Greatly reduce personnel labor and shortened the working time, improved operating efficiency.
