Description
Technical field
The utility model 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 a technological means of utilizing rock and soil drilling, lays, changes and repair various underground utilities under the condition of do not ditch on the face of land (groove).Compare with traditional construction method, the non-excavating construction method have do not destroy environment, do not influence traffic, advantage such as short construction period, integrated cost are low, obvious social benefit.Be particluarly suitable for the area that some can't implement to excavate operation; as business district, urban road, speedway, railway, building, river, crops and vegetation protection district etc., can be widely used in 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 and lays distance underground pipelines more longways 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 lead drilling technology construction depth depends on the guiding degree of depth of guide instrument.
Guiding drilling construction technology mainly comprises pilot hole, reaming and trombone slide three parts, and it the most important thing is the design and the construction of pilot hole.The design of pilot hole and construction are subjected to the restriction of many factors, wherein most importantly the ground of job site and underground condition.Ground condition comprises landform, landforms and surrounding buildings thing, 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 that guiding is crept into no-dig laying pipelines technique.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 the pipeline laid drawing in the boring promptly and accurately should be guaranteed not collapse the hole and as few as possible well cuttings is entered sleeve pipe.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of anti-device that draws of the drilling technology that is applied to lead, and 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 portion is provided with 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 is provided with through hole, described through hole is provided with 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.
The utility model has the advantages that: simple in structure, the reliability height, cost is low.

The specific embodiment
Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises composite member rig catcher 1, anti-device connector 2, the anti-device PVC hot melt part 3 that draws of drawing;
Shown in Fig. 2-1,2-2, 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;
Shown in Fig. 3-1,3-2, the described anti-device connector 2 that draws is for "T"-shaped, and bar portion 202 is provided with screw thread and matches with the screw 103 of composite member rig catcher 1;
Shown in Fig. 4-1,4-2, the described anti-device PVC hot melt part 3 that draws is for cylindrical, and the centre is provided with through hole 301, and described through hole 301 is provided with projection 302;
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 utility model is that drilling rod is connected with rig, and the other end of drilling rod is connected with the utility model, pipeline is connected with the utility model again.Whenever draw in a pipeline, weld a pipeline more in the back, until all drawing 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, during except that welded pipe line, interruption midway.
