Description
Technical field
The utility model belongs to mining construction technical field, specifically, and particularly a kind of underground coal mine pipe connecting structure.
Background technique
At present, construction underground coal mine Pipe installing engineering, because underground coal mine does not allow pipeline welding to connect, therefore can only ground processing and fabricating, down-hole installation.Placement between underground coal mine pipeline, is updated to present mining fast connector by traditional Flange joint and connects.Fast connector is generally made up of symmetrically arranged short tube shape linkage section and anchor ear, adopts the deficiency existing for fast connector connecting tube to be:
1) structure is comparatively complicated, and cost is higher;
2) need to beat groove on pipeline before assembling, can operation be increased, reduce efficiency of construction;
3) quality requirement linkage section being welded in pipe head is high, and welded seam is many, correspondingly high to the technical requirements of construction worker, thereby increases difficulty of construction, also can affect the progress of construction.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of underground coal mine pipe connecting structure that effectively can reduce difficulty of construction, accelerating construction progress.
Technical solutions of the utility model are as follows: a kind of underground coal mine pipe connecting structure, comprise the first pipeline (1) and the second pipe (2) of coaxial line layout, described first pipeline (1) connects with the opposite end of second pipe (2), anchor ear (3) is set with at the first pipeline (1) and the outside of second pipe (2) joint, setting-in first steel ring (4) in the annular groove of this anchor ear (3) one end inwall, first steel ring (4) ring set is on the first pipeline (1), and fixed by welding and the first pipeline (1), setting-in second steel ring (5) in the annular groove of anchor ear (3) the other end inwall, second steel ring (5) ring set is on second pipe (2), and the second steel ring (5) is fixed by welding and second pipe (2).
Adopt above technological scheme, the steel ring made in advance is set with and is welded in pipeline near port, when underground coal mine pipeline construction, only need by two pipeline docking, then hold tightly with the butt end of anchor ear by two pipelines, two pipelines can be fixed together.The two ends of anchor ear embed spacing by the steel ring on pipeline, can effectively prevent anchor ear from moving axially, thus ensure that the soundness that pipeline connects and reliability.Compared with background technique, the utility model has saved the Master Cost buying rapid pipe joint linkage section, and does not need to beat groove welding on pipeline, has not only saved cost of labour and material cost, and has simplified operation, effectively improve efficiency of construction.The utility model can reduce welding operation quality, low to the technical requirements of construction worker, just can construct, reduce construction cost with simple instrument, and energy accelerating construction progress, can apply at various underground coal mine.
Conveniently draw materials, reduce costs, facilitate processing and fabricating, and guarantee structural strength, described first steel ring (4) and the second steel ring (5) form by the Round Steel Bar coiling that diameter is 6.5mm.
In order to prevent corrosion, increasing the service life, being coated with rust proof paint on the surface of described first steel ring (4) and the second steel ring (5).
In order to ensure sealing, prevent pipeline junction from leaking, between described anchor ear (3) and the first pipeline (1) and between anchor ear (3) and second pipe (2), be provided with seal ring, described seal ring is positioned between the first steel ring (4) and the second steel ring (5).
Beneficial effect: the utility model structure is simple, and assembly manipulation is convenient, ensureing that pipeline is connected firmly, conduit running is reliable while, effectively can save construction cost, accelerates the construction period.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model is made up of the first pipeline 1, second pipe 2, anchor ear 3, first steel ring 4, second steel ring 5 and seal ring.Wherein, first pipeline 1 on the left side is arranged with second pipe 2 coaxial line on the right, and the right-hand member of the first pipeline 1 and the left end of second pipe 2 connect, be set with anchor ear 3 at the first pipeline 1 with the outside of second pipe 2 joint, by anchor ear 3, first pipeline 1 and second pipe 2 be fixed together.
As shown in Figure 1, the Round Steel Bar coiling that in the annular groove of anchor ear 3 left end inwall, setting-in first steel ring 4, first steel ring 4 is preferably 6.5mm by diameter forms, and ring set is on the first pipeline 1, and the first steel ring 4 is fixed by welding and the first pipeline 1.Rust proof paint is coated with, to prevent corrosion on the surface of the first steel ring 4.The Round Steel Bar coiling that in the annular groove of anchor ear 3 right-hand member inwall, setting-in second steel ring 5, second steel ring 5 is preferably 6.5mm by diameter forms, and ring set is on second pipe 2, and the second steel ring 5 is fixed by welding and second pipe 2.Rust proof paint is coated with, to prevent corrosion on the surface of the second steel ring 5.Between anchor ear 3 and the first pipeline 1 and be provided with seal ring between anchor ear 3 and second pipe 2, described seal ring, between the first steel ring 4 and the second steel ring 5, leaks to prevent the joint of two pipelines.
The each steel ring of above structure is weldingly fixed on corresponding pipeline in advance, assembling anchor ear and seal ring when pipeline connects.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
