Abstract
The utility model provides a connecting structure for steel reinforced spirally wound polyethylene pipes used in underground coal mines. The connecting structure comprises two pipes, the cross sections of the two pipes aligned with each other; soft polyethylene seal blocks are packed in grooves formed by adjacent reinforcing ribs on the outer sides of the adjacent pipes; the height of the seal blocks is the same as the height of the reinforcing ribs of the pipes; a rubber sleeve is sleeved on the periphery of the seal blocks; a foaming rubber plate is disposed on the outside of the rubber sleeve; the foaming rubber plate is wrapped up by a stainless steel plate; and two ends of the stainless steel plate are in snap fit with each other through locking fasteners. The connecting structure improves pressure-resisting capacity of the pipes greatly, is easy to manufacture and is especially suitable for the manufacture of pipelines with large diameters. The connecting structure enables a great amount of PE to be saved in the manufacture of the pipes, enables the cost of the pipes to be reduced, enables the overall weights of the pipes to be reduced greatly, and facilitates construction and transportation. The connecting structure realizes the connection of the pipes with the rubber sleeve, the foaming rubber plate and the stainless steel plate, realizes easy and rapid construction, and reduces labor intensity and the pipe cost greatly.
Description
Technical field
The utility model relates to a kind of linkage structure of novel underground mine use plastic steel composite pipe material, especially the linkage structure of underground mine use ventilation plastic-steel spirally-wound pipe material.
Background technique
The main feature of polyvinyl plastics tubing is (its unit weight be merely steel pipe 1/8) in light weight, easy construction; Tube wall is highly polished, and fluid resistance is little, and is less scaling; Corrosion-resistant, characteristics such as long service life are national in recent years a kind of products of wideling popularize application.Polyethylene pipes for underground mine use mainly is in the tubing course of working, to add the corrosion resistance that flame-retardant master batch and antistatic master batch reach the usage requirement, particularly polyvinyl piping materials of flame-retardant and anti-static, is more suitable for various humidities and corrosive environment under the coal mine.
But because the characteristics of polyvinyl piping materials self; Be that the tubing rigidity is lower, reach the ring stiffness that usage requirement must increase tubing through the method that increases wall thickness, the big increase of materials of Here it is tubing; Especially in larger caliber (on the tubing of DN ≧ 200mm); And the connection between the polyvinyl piping materials is through two PE flanged joints of hot melt butt joint, on two flange heads, puts a corrosion-resistant steel flange sheet more respectively, connects through bolt; Not only connect trouble, and on cost, will increase a lot.The weight of tubing itself adds the Placement between tubing and the tubing, makes the cost of whole pipe quite high.
Summary of the invention
The purpose of the utility model is to provide the underground mine use plastic-steel spirally-wound pipe material that a kind of bearing strength is high, easy to connect, overall cost is low linkage structure.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of underground mine use polyethylene plastic-steel spirally-wound pipe material; Be general polyethylene plastic-steel spirally-wound pipe material; The outer surface of said tubing is provided with the stiffening rib of helical, in said stiffening rib, is provided with the steel band skeleton.
Described steel band is " 1 " shape.
One underground mine use polyethylene plastic-steel spirally-wound pipe material linkage structure; Be characterised in that: the tubing that comprises two section alignment; Soft polyethylene sealing block is packed in respectively in the groove of being made up of adjacent stiffening rib in the adjacent tubing outside; The height of said sealing block is concordant with the tubing stiffening rib, is nested with rubber sleeve in said sealing block periphery; Outside rubber sleeve, be nested with the bipeltate plate; Bipeltate plate outsourcing coating stainless steel plate, the opening of corrosion resistant plate is fastened and connected through tight locking button.
The beneficial effect of the utility model is:
1, owing to the straight rib structure of pipe material by adopting spiral, the characteristics of this structure are the big raisings of resistance to compression grade of tubing, and convenient the manufacturing especially is fit to make large diameter pipeline.
2, PE part materials significantly reduce in the tubing, and the tubing cost is reduced, and the also greatly reduction of the overall weight of tubing, and construction and transportation are greatly convenient.
3, being connected of tubing and tubing adopts stainless steel to add the glue gum cover to connect, and easy construction is quick, has reduced labor intensity and pipe fitting cost widely.
Description of drawings
Fig. 1 is the stereogram of tubing;
0012]Fig. 2 is the plan view of tubing;
0013]Fig. 3 is the A--A sectional view of Fig. 2;
0014]Fig. 4 is the B place partial enlarged drawing among Fig. 3;
0015]Fig. 5 is the scheme of installation of the utility model;
0016]Among the figure: 1 polyethylene hybrid resin layer, 2 steel bands, 11 stiffening ribs, 3 weld seams, 4 sealing blocks, 5 rubber sleeves, 6 bipeltate plates, 7 corrosion resistant plates, 8 tight locking buttons.
Embodiment
Like Fig. 1～shown in Figure 5,
0018]A kind of underground mine use polyethylene plastic-steel spirally-wound pipe material; Be general polyethylene plastic-steel spirally-wound pipe material, tubing adds and flame-proof antistatic master material is added in the polyethylene resin heat fused man-hour; Extrude and simultaneously steel band is coated through specialized mould; Form a kind of compound strip band of being made up of polyethylene hybrid resin layer 1 and steel band 2 skeletons, the steel band skeleton is located in the stiffening rib 11, and the shape of steel band wherein comprises the form among Fig. 4 at least.When outer field polyethylene hybrid resin layer plays the flame-retardant and anti-static effect, simultaneously steel band also had antisepsis.Through mould the band of producing is curled into tubing through tube-forming machine again, and is welded, form the weld seam 3 shown in figure, be the structural representation of the utility model.
This tubing has light weight and high-intensity advantage.Concrete method for using in the engineering is:
At first the plane is processed at the tubing two ends, with two tubing alignment, soft polyethylene sealing block 4 is packed in the groove in the tubing outside then, the height of said sealing block 4 is concordant with tubing stiffening rib 11, is convenient to fill satisfactory.Be nested with rubber sleeve 5 in sealing block 4 peripheries, rubber sleeve is nested with bipeltate plate 6 outward, bipeltate plate outsourcing coating stainless steel plate 7, and the opening of corrosion resistant plate is fastened and connected through tight locking button 8, and two tubing become one, and connect to accomplish.
In the utility model, because the straight rib structure of pipe material by adopting spiral composite steel band, the characteristics of this structure are the big raisings of resistance to compression grade of tubing; PE part materials significantly reduce in the tubing, the tubing cost is reduced, and the overall weight of tubing also greatly reduce; Construction and transportation are greatly convenient, and the employing stainless steel that is connected of tubing and tubing adds the glue gum cover and connects easy construction; Fast, labor intensity and pipe fitting cost have been reduced widely.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
