Description
Technical field
The present invention relates to the engineering equipment field, is a kind of anti-device that draws of the drilling technology that is applied to lead specifically.
Background technology
Non-excavating construction is the technological means of utilizing rock and soil drilling, lays, changes and repair various underground utilities under the condition of do not ditch on the earth's surface (groove).Compare the advantage such as the non-excavating construction method has not welding, do not affect traffic, short construction period, integrated cost is low, social benefit is remarkable with traditional construction method.Be particluarly suitable for the area that some can't implement to excavate operation; such as business district, urban road, speedway, railway, building, river, crops and vegetation protection district etc., can be widely used in the pipelines such as municipal administration, water supply, combustion gas, electric power, telecommunications, heating power.The guiding drilling technology is a kind of non-excavating construction method with fastest developing speed, and it is mainly used in laying more longways underground pipelines of distance in broken ground.Its advantage is that surface drying is disturbed less over the ground, and speed of application is fast, can control construction direction, and precision is higher.But difficulty of construction should be utilized the mud off pore-forming more greatly when constructing in sand gravel layer, and wire drilling technology construction depth depends on the guiding degree of depth of guide instrument.
Guiding is crept into construction technology and is mainly comprised pilot hole, reaming and trombone slide three parts, and it the most important thing is design and the construction of pilot hole.Multifactorial restriction is permitted in the design of pilot hole and construction, wherein most importantly the ground of job site and underground condition.Ground condition comprises landform, landforms and Adjacent Buildings, road, river etc.; Underground condition comprises original underground utilities, underground water and formation condition etc.Therefore, must labor field investigation data before pilot hole design and construction.
Trombone slide is last procedure of Trenchless Pipeline Installation Technique Using Guided Boring.The success or failure of trombone slide process depend primarily on instead draws whether success of device design, because anti-function of drawing device at first should have reaming, secondly should with the pipeline laid drawing in the boring promptly and accurately, guarantee not collapse the hole and as few as possible well cuttings is entered sleeve pipe.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of anti-device that draws of the drilling technology that is applied to lead, concrete scheme is:
A kind of anti-device that draws of the drilling technology that is applied to lead, comprise drilling rod, composite member rig catcher, anti-device connector, the anti-device PVC hot melt part that draws of drawing, described composite member rig catcher is shaped as and cylindrically combines with truncated cone-shaped, the centre is provided with screw, the described anti-device connector that draws is "T"-shaped, bar section arranges screw thread and matches with the screw of composite member rig catcher, the described anti-device PVC hot melt part that draws is cylindrical, the centre arranges through hole, described through hole arranges projection, and the diameter in the described hole that convexes to form is less than the anti-diameter that draws device connector end; The described anti-diameter that draws device PVC hot melt part diameter to be less than or equal to composite member rig catcher column part; Composite member rig catcher is connected with drilling rod, and the anti-device connector that draws is threaded with composite member rig catcher; The anti-end of device connector of drawing embeds the anti-annulus that convexes to form that draws device PVC hot melt part; The anti-device PVC hot melt part that draws is connected with pipe hot melting.
For preventing in use, anti-when drawing device and drilling rod to be out of line, the anti-device connector that draws is not that face contacts and the stress that causes is concentrated with counter drawing between device PVC hot melt part, thereby to anti-infringement of drawing device PVC hot melt part, so that anti-device connector and the anti-device PVC hot melt part that draws of drawing disconnects, described anti-device connector one end that draws is for spherical, and the described anti-device PVC hot melt part appropriate section of drawing is also for spherical, and the described anti-device PVC hot melt part that draws arranges the inclined-plane with the described anti-corresponding part of bar section of device connector of drawing.
Advantage of the present invention is: simple in structure, reliability is high, and cost is low.

The specific embodiment
Specify the present invention below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes composite member rig catcher 1, anti-device connector 2, the anti-device PVC hot melt part 3 that draws of drawing; As shown in Figure 2, described composite member rig catcher 1 is shaped as cylindrical 102 and combines with truncated cone-shaped 101, and the centre is provided with screw 103; As shown in Figure 4, the described anti-device PVC hot melt part 3 that draws is for cylindrical, and the centre arranges through hole 301, and described through hole 301 arranges projection 302;
For preventing in use, anti-when drawing device and drilling rod to be out of line, the anti-device connector that draws is not that face contacts and the stress that causes is concentrated with counter drawing between device PVC hot melt part, thereby to anti-infringement of drawing device PVC hot melt part, so that anti-device connector and the anti-device PVC hot melt part that draws of drawing disconnects, as shown in Figure 3, Figure 4, described anti-device connector 2 one ends that draw are spherical 21, described anti-device PVC hot melt part 3 appropriate sections of drawing are also for spherical, and the described anti-device PVC hot melt part 3 that draws arranges inclined-plane 31 with the described anti-corresponding part of bar section of device connector 2 of drawing.
Such as Fig. 1, shown in Figure 5, the diameter in described protruding 302 holes that form is less than the anti-diameter that draws device connector end 201; Described anti-device PVC hot melt part 3 diameters that draw are less than or equal to the diameter that the composite member rig is taken over 1 cylindrical part 102; Composite member rig catcher 1 is connected with drilling rod 4, and the anti-device connector 2 that draws is threaded with composite member rig catcher 1; The anti-end 201 of device connector 2 of drawing embeds the anti-annulus that draws projection 302 formation of device PVC hot melt part 3; The anti-device PVC hot melt part 3 that draws is connected with pipe hot melting.
As shown in Figure 5, using method of the present invention is that drilling rod is connected with rig, and the other end of drilling rod is connected with the present invention, pipeline is connected with the present invention again.Whenever draw in a pipeline, weld in the back again a pipeline, until all draw in.Axiality between the two must be guaranteed when welding between the pipeline, otherwise the trombone slide resistance will be increased.During trombone slide, combine with truncated cone-shaped 101 because described composite member rig catcher 1 is shaped as cylindrical 102, thus composite member rig catcher while turn round trombone slide, the trombone slide process will once be finished, when removing welded pipe line, interruption midway.
