Abstract
The invention relates to an enhanced mine-used wind extracting-exhausting pipe of a spiral type, which is characterized in that a spirally winding enhanced structure layer with an externally convex hollow section is jointed outside a core layer of a pipe wall formed by spirally winding strips mutually lapped and melted in sequence; an outer wall layer formed by the spirally winding strips is melted and covered outside the pipe wall; wherein, at least one gas channel structure used for leading a pipe cavity inside the core layer of the pipe wall to be communicated with an externally convex hollow space in the enhanced structure layer is arranged on the position corresponding to the externally convex hollow space of the enhanced structure layer on the core layer of the pipe wall. The wind extracting-exhausting pipe is particularly applicable to being used in mines in complex and severe environment; the weight is greatly reduced and when the wind is extracted or exhausted, space surrounding pressure of hollow peak in the enhanced structure can be consistent with the pressure in the pipe cavity, thus eliminating unfavorable impact on a pipe structureand ensuring normal using of the pipe; besides, the outer wall layer of the further thickened externally convex part of the pipe wall also improves the performance of the scraping resistance of the pipe .
Description
Technical field
The utility model relates to and a kind ofly is provided with the helical bellows that metal strengthens structure in the welding mode in tube wall, and it is a kind ofly can be suitable for mining spiral enhancement mode pump drainage airduct that the spy adds.
Background technology
Be to guarantee and improve the requirement of downhole safeties productions such as coals mining, mining, the pump drainage standard and the requirement of the danger such as gas under the mine, pernicious gas improved constantly, and the Device in Gas that goes out of pump drainage puts together the comprehensive utilization that also can be used for generating electricity etc. and turn waste into wealth.The tubing of using as down-hole pump drainage wind, if with the pipe of real wall type, its weight is too big and cost is high; If that adopts conventionally form is provided with the helical double-wall corrugated tube that steel plate etc. strengthens structure in the welding mode in tube wall, owing to what isolated mutually by the sandwich layer of tube wall between spiral surrounding space in the evagination hollow crest that is evagination hollow form cross section in its steel plate enhancing structure and the tube chamber, therefore in pump drainage wind process, be negative pressure state in the tube chamber, then still remain conventional barotropic state in the ambient in this hollow crest of enhancing structure, this pressure differential can make the sandwich layer in the tube wall push in tube chamber, comes off thereby easily cause this sandwich layer to separate from tube wall.In addition, the situation complexity in the mine, environment is more abominable, and the outer wall layer at the enhancing structure evagination crest place of conventional enhancing helical bellows is thinner usually, has also influenced the anti-scratch performance of tubing.
The utility model content
At above-mentioned situation, the utility model will provide a kind of spiral that is fit to the improvement structure of mining pump drainage wind to strengthen bellows.
The basic structure of the utility model spiral enhancement mode is mining pump drainage airduct, be still in the outside of the tube wall sandwich layer that is formed by the spiral winding band that overlaps fusion successively mutually, it is evagination hollow and the Ω shape metal that has both sides abduction extending pin enhancing deck that joint has the cross section that spiral twines; Be coated with the outer wall layer that the band that twined by spiral forms in the welding of the outside of tube wall.Wherein, being provided with at least one with corresponding position, evagination hollow part that metal strengthens deck on the tube wall sandwich layer is used for making metal to strengthen the pathway structure that this evagination hollow space of deck is communicated with tube chamber in the tube wall sandwich layer.Said this pathway structure, can be the simplest through-hole structure form, better can also be adopted as and to have the valve arrangement that opens and closes function, particularly for example also dispose the one way valve of suitable black box simultaneously, can effectively avoid ducted water enter metal strengthen this evagination hollow space in the deck and cause unfavorable.
On the said structure basis, for further improving aforementioned tubes anti-scratch performance in use, the pipe outer wall layer that said metal strengthens the evagination hollow part of deck can be adopted as the two spirals winding band that twines successively by front and back overlaps formation mutually with the edge double-deck form thickening outer wall layer.
Strengthen the reliability that is bonded with each other between deck and inside/outside layer plastics winding band for said metal in assurance and the raising tube wall; the surface that strengthens deck at metal can also be coated with single or multiple lift protective material layer; add coating as zinc coat, or epoxy resin layer adds the sandwich construction of forms such as coating.
In said structure, for ease of the connection between two tubing in the construction, having the jointing structure that can cooperatively interact respectively at the two ends of above-mentioned pump drainage airduct is the measure of using always.For guaranteeing tube chamber and extraneous sealing, and tube chamber is communicated with the effective of this evagination hollow space that metal strengthens in the deck, be filled with plugging structure strengthening in the evagination hollow part of deck, and be provided with at least one above-mentioned pathway structure equally in the pipeline section between two plugging structures of this correspondence with each jointing structure adjacent metal.The jointing structure of said pipe end, according to using needs, pipe end plane that connects usefulness and the ring male structure that can match with jointing clip simultaneously can be to have, also holding/outlet structure of can doing respectively that spigot-and-socket cooperates can be, or other suitable form of structure.
Further, guaranteeing to satisfying and guaranteeing to use under the situation of needs, alleviate the weight and the cost of production of tubing for decrement, can also make ratio 〉=24 that metal strengthens Laminate construction thickness in said lumen diameter and the tube wall, promptly suitably reduce the evagination height that metal strengthens structure, though reduced the ring stiffness of tubing relatively, the making of tubing will be easier, and cost is lower.
In addition, the ratio of height and the overhanging width of its abduction extending pin that said metal in the said structure is strengthened the evagination hollow section of deck is reduced to≤and 4, the metal that promptly suitably extends strengthens the overhanging width of deck abduction extending pin, thereby it is more close to make adjacent metal strengthen deck abduction extending pin, thereby also can reach the ability that metal external force resistance such as strengthen that opposing ore in deck trough place is pounded, presses, stings, cut destroys that improves.
The pump drainage airduct of the utility model said structure form, when in the mine of situation complexity and adverse circumstances, using, not only in light weight, and in pump drainage wind process, can make tube chamber remain consistent with the ambient pressure of the hollow crest that strengthens structure, eliminated adverse effect to structural pipe wall, guaranteed the normal use of tubing, further the tube wall male part of thickening divides outer wall layer also to improve the anti-scratch performance of tubing, has prolonged application life.
Below in conjunction with the specific embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
