Abstract
The utility model provides a compound trombone slide cover is moulded to steel, this compound trombone slide cover is moulded to steel include that the trombone slide overlaps and moulds the coupling, and the trombone slide overlaps one end and moulds the coupling and is connected, and lug and otic placode are installed to the other end, still include the endotheca of connecting the trombone slide and overlapping and mould the coupling, endotheca one end fixed connection is in the inner circle of trombone slide cover, and the other end is through external screw thread and the interior screw thread fit connection that moulds the coupling to be equipped with at trombone slide cover and the cooperation position outer lane cover of moulding the coupling and press the cover, not firm, the easy problem that lost efficacy etc. That this compound trombone slide cover is moulded to steel can solve in the construction dilatory plastic tubing.
Description
technical field:
The utility model relates to a kind of steel plastic compount Connecting tube hose, is widely used in the underground pipeline project constructions such as rock gas, coal gas, heating power, electric power, communication, plumbing and cable television.
background technique:
No-dig technique horizontal directional drilling machine is used in not digging mode and carries out underground stringing, and the Construction Principle of horizontal orientation boring is directionally controlled in one, and under the condition of not excavating earth surface, carries out underground pipeline layout, replacing or reparation.
Under normal circumstances, after the boring of no-dig technique horizontal directional drilling machine terminates, connect steel Connecting tube hose in outlet port by drilling rod and be connected by the plastic tube dragged with on ground, more whole plastic tube is oppositely retracted inlet.Present steel Connecting tube hose is generally formed by connecting by being connected accessory by many group screw thread latches with binding steel wire etc. between Connecting tube hose and plastic pipe union.Its working principle is: steel Connecting tube hose one is connected to the head of drilling rod, and other end is connected by the plastic tube dragged by steel sleeve pipe, is then dragged into by the plastic pipe of whole on building site in the cavity of having excavated and goes, carry out underground stringing.
But this steel Connecting tube hose structure comes with some shortcomings, more mainly due to the accessory between steel Connecting tube hose and joint for plastic tube, field fabrication is cumbersome, connect operation more loaded down with trivial details, and use screw thread latch join strength uncertain, be unfavorable for no-dig technique pick job execution.
summary of the invention:
The utility model, for above-mentioned prior art Problems existing, provides a kind of steel plastic compount Connecting tube hose.
Concrete technological scheme of the present utility model is as follows:
A kind of steel plastic compount Connecting tube hose, comprise Connecting tube hose and plastic pipe union, Connecting tube hose one end is connected with plastic pipe union, the other end is provided with lug and otic placode, also comprise the inner sleeve connecting Connecting tube hose and plastic pipe union, described inner sleeve one end is fixedly connected on the inner ring of Connecting tube hose, and the other end is connected with the screw-internal thread fit of plastic pipe union by outside thread, and at the cooperation position outer ring sleeve of Connecting tube hose and plastic pipe union, gland is housed.
Further design of the present utility model is:
Described inner sleeve one end and Connecting tube hose inner ring adopt welding manner to be connected.
The screwing position of inner sleeve and plastic pipe union is also coated with tackiness agent.
Described Connecting tube hose, inner sleeve, gland and overcoat all adopt steel material.
The utility model tool has the following advantages:
1, steel plastic compount Connecting tube hose of the present utility model directly with hot-melting machine by by the plastic pipe union hot melt dragged on plastic tube and Connecting tube hose, simple to operate, joint connection in site pipeline operating rate is fast, and working efficiency is high.
2, after this steel plastic compount Connecting tube hose hot melt, trombone slide joint and dragged plastic pipe join strength to improve, firm and reliable connection, not easy-rupturing, can ensure construction quality.
3, the original position after engineering terminates of the plastic pipe union on Connecting tube hose is cut off, and the plastic pipe union stayed on steel plastic compount Connecting tube hose can also be reused.
4, to eliminate accessory in existing structure many for this steel plastic compount Connecting tube hose, eliminate the tedious work such as the trouble of on-the-spot processing many groups screw thread latch and binding steel wire.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1-gland; 2-inner sleeve; 3-Connecting tube hose; 4-lug; 5-otic placode; 6-plastic pipe union.
embodiment:
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1, the structure of steel plastic compount Connecting tube hose of the present utility model is as figure below: it is made up of elements such as gland 1, inner sleeve 2, Connecting tube hose 3, lug 4, otic placode 5 and plastic pipe unions 6, can solve the problem of not firm, the easy inefficacy of tracking plastic pipe in construction etc.
In Fig. 1, Connecting tube hose 3 one end is connected with plastic pipe union 6, and the other end is provided with lug 4 and otic placode 5, and lug 4 and otic placode 5 are for the head of jointed rod.Connecting tube hose 3 is connected by inner sleeve 2 with plastic pipe union 6, and inner sleeve 2 one end is fixedly connected on the internal diameter of Connecting tube hose 3, and inner sleeve 2 the other end is provided with outside thread, and adaptive with the internal thread of plastic pipe union 6, and internal and external threads is connected.A gland 1 is tightly set with at the outer ring place of the cooperation position of Connecting tube hose 3 and plastic pipe union 6.Gland 1, Connecting tube hose 3 and inner sleeve 2 can adopt steel material.Inner sleeve 2 one end adopts welding manner to be connected with Connecting tube hose 3 endoporus, and the other end is connected with the internal thread of plastic pipe union, is also coated with tackiness agent, to strengthen the intensity of connection further in threaded connection place simultaneously.
Steel plastic compount Connecting tube hose of the present utility model designs for dragging plastic pipe, and it becomes series product.Steel plastic compount Connecting tube hose in figure is one in series product, and its diameter is about 110, is suitable for the plastic pipe such as rock gas, coal gas, electric power, communication dragging similar diameter.
working procedure of the present utility model is as follows:
In figure, 1-gland; 2-inner sleeve; 3-Connecting tube hose; 4-lug; 5-otic placode; 6-plastic pipe union.
The making method of steel plastic compount Connecting tube hose is very simple, it is first by good for the internal thread car of a bit of plastic pipe union 6, again by good for the outside thread car of inner sleeve 2 and be welded into entirety with Connecting tube hose 3, lug 4 and otic placode 5, then the plastic pipe union 6 of good for car screw thread is screwed in inner sleeve 2, last again gland 1 to be locked on the external diameter of plastic pipe union 6 and Connecting tube hose 3, to bind round jail tightly.
The working procedure of steel plastic compount Connecting tube hose is first connected with the head of drilling rod by the otic placode 5 of one head, other end is connected through hot melt with by the plastic tube head of same diameter dragged by a bit of plastic pipe union 6 on steel plastic compount Connecting tube hose, is dragged into by the plastic pipe of whole on building site like a cork in the cavity of having excavated goes finally by the drilling rod of rig.
