Abstract
The utility model relates to an anti-collapse sleeve and a component. The anti-collapse sleeve is provided with a sleeve (1) and a sleeve head (2), wherein the sleeve (1) is a cylindrical hollow pipe. The anti-collapse sleeve and the component are characterized in that the sleeve head (2) is also a cylindrical hollow pipe; and the diameter of nozzles at two ends is slightly larger than that of the pipe wall at the middle part. The anti-collapse sleeve and the component have the advantages that the defect that the external thread is easy to damage during the conveying process is overcome; a novel sleeve joint is made of seamless steel pipes so as not easily cracked by pressure during the using process; furthermore, as the diameter of the sleeve joint is equal to that of the sleeve, the friction force of the sleeve joint and the boring wall is reduced when the sleeve joint is dropped into the sleeve, and the sleeve is easier to be dropped into the bore deeply, so that the anti-collapse sleeve is more convenient and quicker during the using process.
Description
One, affiliated field
The utility model relates to a kind of sleeve pipe and assembly, prevents assembly between the sleeve pipe of borehole collapse and the splicing sleeve especially for ature of coal than soft seam.
Two, background technology
Along with the exploitation in colliery puts more effort, gas and fire safety problem are outstanding gradually.In order effectively to administer similar problem, in the coal seam, construct usually, promptly dig firedamp taking-out discharging drilling and fire prevention inlet well.When ature of coal is softer, often need in boring, put into anti-collapse sleeve pipe.At present the most frequently used is exactly to put into multistage and the seamless steel pipe that boring adapts, and adopts corresponding box cupling to connect between each steel pipe.But the seamless steel pipe of being put into need be made outer silk, in the transportation of down-hole, can cause screw thread to be broken unavoidably, makes sleeve pipe normally to connect.Simultaneously, box cupling is than the big 2-3mm of outer diameter of steel pipes, when steel pipe down, increased the friction of box cupling with rib around the boring, and steel pipe is difficult to down to foot of hole.Generally speaking, box cupling is that the pig iron is made, and in following steel pipe process, being subjected to external force effect box cupling breaks easily, causes the guard aperture failure.
Three, utility model technology contents
The purpose of this utility model is to overcome existing anti-anti-collapse sleeve pipe and the existing defective of box cupling, and a kind of novel anti-collapse formula sleeve pipe and assembly are provided.
In order to realize described purpose, the utility model is according to following technical scheme.Anti-collapse formula sleeve pipe and assembly have sleeve pipe and pullover, and sleeve pipe is a columniform hollow tube, it is characterized in that described pullover also be a columniform hollow tube, the slightly larger in diameter of its two ends mouth of pipe is in the diameter of middle part tube wall.
The diameter of the diameter of described pullover 2 middle part tube walls and sleeve pipe 1 is corresponding.
Superior part of the present utility model is to have overcome the easy ruined shortcoming of outer silk at transportation middle sleeve mouth; The new casing joint adopts seamless steel pipe made, makes in use to be difficult for by pressure break; Because the casing joint diameter is corresponding with casing diameter, reduced when being lowered to sleeve pipe again, the frictional force of casing joint and boring perisporium, sleeve pipe is easier down to the boring deep, and is feasible in use convenient, quick.
Four, description of drawings
Fig. 1 is the signal of the utility model thimble assembly package assembly.
Fig. 2 is the utility model sleeve structure schematic diagram.
Five, the specific embodiment
Anti-collapse formula sleeve pipe and assembly have sleeve pipe 1 and pullover 2, and described sleeve pipe 1 is a columniform hollow tube, and described pullover 2 also is a columniform hollow tube, and the slightly larger in diameter of its two ends mouth of pipe is in the diameter of middle part tube wall.
The diameter of described pullover 2 middle part tube walls and the diameter of sleeve pipe 1 should be a kind of situation of the best mutually.
During normal the use, at first first sleeve pipe 1 is lowered in the boring, then first pullover 2 is inserted in first sleeve pipe 1, slowly an end of second sleeve pipe 1 is enclosed within first other end of pullover 2 subsequently again and finishes once and peg graft; So continue, all sleeve pipes are arrived the boring deep down always.
Claims (2)
1. anti-collapse formula sleeve pipe and assembly have sleeve pipe (1) and pullover (2), and sleeve pipe (1) is a columniform hollow tube, it is characterized in that described pullover (2) also are a columniform hollow tube, and the slightly larger in diameter of its two ends mouth of pipe is in the diameter of middle part tube wall.
2. anti-collapse according to claim 1 formula sleeve pipe and assembly is characterized in that the diameter of pullover (2) the middle part diameter of tube wall and sleeve pipe (1) tube wall is corresponding.
