Abstract
The invention discloses a pipeline tapping and shunting device which is high in installation efficiency and reliable in quality. A drill body comprises a pipe body and a drill bit, a fixing body comprises an upper fixing ring and a lower fixing ring, a guide sleeve is arranged between the pipe body and the drill bit, the upper portion of the guide sleeve is matched with the pipe body in a spiral mode, the rod part of the drill bit is located in the guide sleeve and matched with the guide sleeve in a rotating mode, a radial hole is formed in the upper portion of the guide sleeve, a hexagon counter bore is formed in the top of the drill bit, and the lower end of the pipe body and the upper fixing ring of the fixing body are connected into a whole in a screwed mode. The guide sleeve is rotated when drilling is conducted, and meanwhile the top of the drill bit is rotated; due to the fact that the guide sleeve is converted to move downwards through rotation operation, labor is saved, force application is even, and the quality of drilling is high; when the rotary force is not applied, the guide sleeve is not prone to rebound, operation is convenient, and the work efficiency is high.
Description
Technical field
The present invention relates to a kind of device of pipeline flow dividing.
Background technology
When needing interim installation lateral on pressure of supply water pipeline under certain conditions, generally main pipe system need be closed, then the position of installing lateral is being needed, boring increases threeway, reach and lateral object is installed, this mode can bring inconvenience, and impact life or industrial water, can cause stop work and production time serious.There has been the device that boring of not cutting off the water with pressure connects subtube, primarily of wellbore part and fixed part composition, fixed part is arranged on the position of pipeline being wanted perforate, and wellbore part is spirally connected with fixed part and is integrated.Wellbore part is primarily of shell and drill bit composition, rotary drilling head rod portion, one side during operation, make drill bit rotary-cut pipeline, also need ceaselessly to press down drill bit simultaneously, make drill bit apply the pressure of cutting to deferent, but the mode of this applying power affects larger by human factor, time one long easy tired consumptive disease, the power of applying is also uneven, not easily controls two actions during operation simultaneously, cause the second-rate of rotary-cut pipeline, time serious, cause road waste.
Summary of the invention
The object of this invention is to provide the device of a kind of installation effectiveness higher and pipeline perforate of reliable in quality shunting.
Technical scheme of the present invention is: comprise drill body and fixed body, described drill body comprises body and drill bit, described fixed body comprises retainer plate and lower retainer plate, be provided with fairlead between body and drill bit, described fairlead top caliber is less than bottom caliber, fairlead top and body threaded engagement, the bar portion of drill bit be positioned at fairlead and with fairlead rotatable engagement, fairlead top is provided with radial hole, and drill bit top is provided with hexagon counterbore, and the upper retainer plate on body lower end and fixed body is spirally connected and is integrated.
Dust cap spiral cover is at body top.
Snap ring is provided with above the bar portion of described drill bit.
Fixed collar top inner wall is embedded with seal washer.
The structure being provided with fairlead between body and drill bit is adopted in the present invention.Fairlead top external diameter is less than lower outer diameter, fairlead top and body threaded engagement, the bar portion of drill bit be positioned at fairlead and with fairlead rotatable engagement, fairlead top is provided with radial hole, and drill bit top is provided with hexagon counterbore.Therefore, during boring, the front end of the instrument of rotary guide sleeve is inserted very long rotation in the radial hole set by fairlead top and apply pressure, meanwhile, insert with hexagon in the hexagon counterbore at drill bit top and rotate, and only need to rotate.Move downward because fairlead is converted into by rotation process, not only laborsaving, and uniform force application, the quality of boring is also high, and the fairlead also not easily resilience when not applying revolving force, convenient operation, operating efficiency is higher.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail, but does not form any limitation of the invention.Shown in Fig. 1 and Fig. 2, the present invention includes drill body and fixed body.Shown in Fig. 3 to Fig. 5, described drill body comprises body 1 and drill bit 3.Shown in Fig. 6 to Fig. 8, described fixed body comprises retainer plate 5 and lower retainer plate 6.Shown in Fig. 4, fairlead 2 is provided with between body 1 and drill bit 3, described fairlead 2 top caliber is less than bottom caliber, fairlead 2 top and body 1 threaded engagement, the bar portion of drill bit 3 be positioned at fairlead 2 and with fairlead 2 rotatable engagement, fairlead 2 top is provided with radial hole, and drill bit 3 top is provided with hexagon counterbore.Shown in Fig. 1 and Fig. 2, the upper retainer plate 5 on body 1 lower end and fixed body is spirally connected and is integrated.For preventing dust and colliding with, shown in Fig. 1 to Fig. 5, dust cap 4 spiral cover is at body 1 top.For reducing the idle stroke of fairlead 2, needing to make drill bit 3 be reduced to minimum with the axial gap of fairlead 2, and remaining unchanged, shown in Fig. 2 and Fig. 4, the bar portion of drill bit 3 is provided with snap ring 9, and this snap ring 9 is just in time stuck in fairlead 2 top, and drill bit 3 can not be glided in fairlead 2.After preventing perforate, the water in pipeline is emerged, and is provided with sealing ring 10, as shown in Figure 2 and Figure 4 between the bar portion and fairlead 2 of drill bit 3.For preventing the water in pipeline from emerging from fixed body, upper fixed card ring top inner wall is embedded with seal washer 7.As shown in Fig. 2, Fig. 7 and Fig. 8.
During installation, the upper retainer plate 5 of fixed body and lower retainer plate 6 are fixed by bolts on pipeline, then by screwing in below body 1 on upper retainer plate 5, are fastened as a whole with upper retainer plate 5.Screw off lid, insert in the hole above fairlead 2 with instrument, and rotary guide sleeve 2, there is relative rotary motion in fairlead 2 and body 1, and body 1 is fixed on retainer plate 5 motionless, fairlead 2 can only drive drill bit 3 to be forced to together move downward, when drill bit 3 touches pipeline, along with constantly moving downward of fairlead 2, resistance is increasing, when resistance large to a certain extent time to stop the rotation fairlead 2, use hexagon rotary drilling-head 3 again, drill bit 3 is moved in a circle, pipeline cuts out the circular groove of certain depth, now, the resistance that drill bit 3 is subject to reduces gradually, continue rotary guide sleeve 2, drill bit 3 is moved down.Operate and so forth, till cut regular circular hole on pipeline.The pipeline section scaled off will be arrived in the cavity of drill bit 3, because drill bit 3 cavity diameter is greater than drill bit 3 cutting circle diameter, so just can ensure that cutting tip is stuck in inside drill bit 3 inner chamber by top under hydraulic pressure effect in pipeline.Finally, rotary guide sleeve 2 round about, drill bit 3 is moved upward, until drill bit 3 rises to above the flow-guiding mouth 8 on body 1, now, the water in pipeline flows in body 1 by the hole got out, and finally flows out from flow-guiding mouth 8, only from flow-guiding mouth 8 connecting line, just need can reach the object of branch line.After all operations terminates, then dust cap 4 is spun on body 1.
